  3. Metabolic syndrome in acute coronary syndrome

    Objective: To determine the frequency of metabolic syndrome in male patients presenting with acute coronary syndrome Study design: A Descriptive study Place and duration of study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008 Patients and Methods: Male patients with acute coronary syndrome (ACS) were included. Patients having angioplasty (PCI), coronary artery bypass surgery in the past and other co-morbid diseases were excluded. All patients were assessed for the presence of five components of metabolic syndrome including hypertension, HDL-Cholesterol and triglycerides, glucose intolerance and abdominal obesity. Systolic, diastolic blood pressures, waist circumference (WC) and body mass index (BMI) were measured. ECG, cardiac enzymes, fasting glucose and lipid profile were also done. Results: A total of 135 male patients of ACS were studied with a mean age of 54.26 +- 11 years. Metabolic syndrome (MS) was present in 55 (40.7%) patients. MS with all five components was documented in 4 (7.27%) while MS with four and three components was seen in 23 (41.81%) and 28 (50.90%) patients respectively. Only 24 (43.63%) patients with MS had diabetes mellitus, remaining 31(56.36%) were non diabetic. Frequencies of diabetes, hypertension and family history of CAD were significantly higher (p<0.05) in patients with metabolic syndrome as compared to patients with normal metabolic status. Conclusion: Metabolic syndrome is fairly common and important risk factor in patients of IHD. Other risk factors like smoking, dyslipidemia, hypertension and diabetes were also frequently found. Public awareness to control the risk factors can reduce the prevalence of CAD in our country. (author)

  4. [Clinical pathway "Acute Coronary Syndrome"].

    Grimm, W; Maisch, B

    2006-07-01

    The clinical pathway "acute coronary syndrome" of the university hospital Marburg describes the guideline-conform and consented management of patients with ST-segment elevation infarct (STEMI), non-ST-segment elevation infarct (NSTEMI) and Troponin negative unstable angina. A 12-lead ECG recording is made and read in all patients within 10 minutes. All patients with STEMI undergo immediate revascularisation using primary percutanuous catheter intervention (PCI) after administration of basic medical therapy. Primary PCI is also used in all patients with NSTEMI, persistent chest pain, rhythm or hemodynamic instability. Patients with unstable angina, who became free of symptoms after application of basic medication, but who have additional risk factors undergo cardiac catheterisation within 48 hours. Acute myocardial infarction can be ruled out in patients with twofold negative cardiac troponin levels during 6-12 hours. In the absence of further symptoms, these patiens undergo differential diagnostic evaluation of cardiac and extracardiac causes of chest pain. The introduction of this clinical pathway 2 years ago, which was consented before by the hospital board and the clinical directors, has lead to a remarkable improvement in the clinical decision-making at the emergency room of the hospital and reduced the door to intervention time considerably.

  5. Inflammation: a trigger for acute coronary syndrome.

    Sager, Hendrik B; Nahrendorf, Matthias

    2016-09-01

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis' most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

  6. Acute Coronary Syndrome and ST Segment Monitoring.

    Carey, Mary G

    2016-09-01

    Acute coronary syndrome (ACS) is caused by a critical obstruction of a coronary artery because of atherosclerotic coronary artery disease. Three specific conditions are included: ST elevation myocardial infarction, non-ST elevation myocardial infarction, and unstable angina. The ST segment on the electrocardiogram is a sensitive and specific marker of myocardial ischemia and infarction; however, ST segment deviation is regional not global, thus the ECG lead must be placed over the affected region of the myocardium. This article describes ACS and infarction and the use of ST segment monitoring to detect these conditions. PMID:27484662

    2009-01-01

    Ostial left main coronary artery (LMCA) occlusion is rarely seen in patients with acute coronary syndrome. Acute coronary syndrome resulting from an LMCA occlusion is associated with a significant morbidity and mortality rate, if it is managed with fibrinolysis. Electrocardiography can predict LMCA occlusion in patients with acute coronary syndrome. We report a 52-year-old male who presented with acute coronary syndrome and ostial LMCA occlusion.

    2005-01-01

    This review focuses on the modern management of the non-ST elevation acute coronary syndromes (unstable angina and non-ST elevation myocardial infarction). Patients with these syndromes are at varying degrees of risk of (re)infarction and death. This risk can be reliably predicted by clinical, electrocardiographic, and biochemical markers. Aspirin, clopidogrel, heparin (unfractionated or low molecular weight), and anti-ischaemic drugs should be offered to all patients, irrespective of the predicted level of risk. Patients at high risk should also receive a glycoprotein IIb/IIIa receptor inhibitor and should undergo early coronary arteriography with a view to percutaneous or surgical revascularisation. Lower risk patients should undergo non-invasive testing. When inducible myocardial ischaemia is exhibited coronary arteriography should follow. When non-invasive testing is negative, a conservative management strategy is safe. PMID:15811883

  11. Acute Coronary Syndrome- Conservative vs Invasive Treatment

    LIM; Yean Teng

    2001-01-01

    @@atients with Acute Coronary Syndrome (ACS)are a clinical continuum-with patients presenting with unstable angina on one end, with patients with ST elevation myocardial infarction (STEMI) at the other end of the spectrum. In between are those with non- ST elevation myocardial infarction (NSTEMI) The pathophysiology is similar in these patients, namely isruption and fissuring of an atheromatous plaque,leading to enhanced platelet activation and local vasohyperactivity, with reduced flow and thrombus formation. While medical experts have reached consensus in the management of STEMI patients (thrombolysis nd / or percutaneous coronary intervention), optimalmanagement of patients with UA/NSTEMI remainsunclear.

  14. Acute coronary syndrome in pregnant women.

    El-Deeb, Mohammed; El-Menyar, Ayman; Gehani, Abdulrazzak; Sulaiman, Kadhim

    2011-04-01

    The purpose of this article is to review the available information on the pathophysiology, diagnosis, treatment and prognosis of acute coronary syndromes (ST-elevation myocardial infarction [STEMI] and non-ST-elevation myocardial infarction [NSTEMI]) during all stages of pregnancy. We searched the English-language literature indexed in MEDLINE, Scopus and EBSCO host research databases from 1980 through to August 2010 using the indexing terms 'pregnancy', 'ante-,peri-, and postpartum', 'acute coronary syndrome', 'myocardial infarction', 'STEMI' and 'NSTEMI'. Symptomatic coronary artery disease is still infrequent in women of childbearing age, but the recent increase in its prevalence in pregnancy has been attributed to the modern trend of childbearing in older years because many young working women are postponing having children. Although rare, acute pregnancy-related MI is a devastating event that may claim the life of a mother and her fetus. The incidence of MI is estimated at 0.6-1 per 10,000 pregnancies. The case fatality rate has been reported to be 5-37%. Owing to the rarity of the event, information related to MI in pregnancy is derived from case reports and, therefore, is subject to considerable reporting bias. Treatment needs to be prompt and urgent because of the very high mortality rate. Current guidelines for the diagnosis and treatment of MI should be expanded to include pregnancy-related MI. Screening and management of cardiovascular risk factors should be achieved before pregnancy. PMID:21517733

  15. Acute organophosphorus poisoning complicated by acute coronary syndrome.

    Pankaj, Madhu; Krishna, Kavita

    2014-07-01

    We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

  16. Dual pathway therapy in acute coronary syndrome.

    Stachon, Peter; Ahrens, Ingo; Bode, Christoph; Zirlik, Andreas

    2016-08-01

    In 10 % of patients, who suffer an acute coronary syndrome (ACS), a major cardiovascular event occurs despite optimal therapy. The occlusion of the vessel is driven by atherothrombosis, which arises from platelet activation and activation of the coagulation cascade. In the last decade the secondary prevention continuously improved by development of dual anti-platelet therapy with new P2Y12-inhibitors such as clopidogrel, prasugrel, and ticagrelor. Until recently, the coagulation cascade was not targeted in secondary prevention. The coagulation factor Xa plays a crucial role in thrombosis and is elevated in patients after acute coronary syndrome, therefore representing an attractive target for novel therapies in ACS. Former studies with vitamin K antagonists showed reduction of cardiovascular events but increased major bleedings. Two phase-3 trials investigated the role of novel oral anticoagulant agents on top of aspirin and clopidogrel in patients with ACS. The APPRAISE-2 study, which tested the oral factor Xa inhibitor apixaban was prematurely terminated because of an increase of major bleedings in the absence of an effect on cardiovascular events. In contrast, the ATLAS ACS2 TIMI-51 trial interrogating the oral factor Xa inhibitor rivaroxaban in a low dose regimen showed significant reduction of cardiovascular events as well as total mortality. Thus, add-on treatment with low dose rivaroxaban emerged as a new option for patients with ACS. This review illustrates recent advances in the development of antithrombotic therapy in acute coronary syndromes, provides guidance on which patients should receive which therapy for secondary prevention of events, and points out potentially fruitful new strategies for the future of antithrombotic treatment in ACS.

    2004-01-01

    Objective To summarize current understanding of the roles of anti-inflammatory and proinflammatory mechanisms in the development of atherosclerosis and acute coronary syndrome and to postulate the novel concept of inflammation stress as the most important factor triggering acute coronary syndrome. Moreover, markers of inflammation stress and ways to block involved pathways are elucidated.Data sources A literature search (MEDLINE 1997 to 2002) was performed using the key words "inflammation and cardiovascular disease". Relevant book chapters were also reviewed.Study selection Well-controlled, prospective landmark studies and review articles on inflammation and acute coronary syndrome were selected.Data extraction Data and conclusions from the selected articles providing solid evidence to elucidate the mechanisms of inflammation and acute coronary syndrome were extracted and interpreted in the light of our own clinical and basic research.Data synthesis Inflammation is closely linked to atherosclerosis and acute coronary syndrome. Chronic and long-lasting inflammation stress, present both systemically or in the vascular walls, can trigger acute coronary syndrome.Conclusions Inflammation stress plays an important role in the process of acute coronary syndrome. Drugs which can modulate the balance of pro- and anti-inflammatory processes and attenuate inflammation stress, such as angiotensin-converting enzyme (ACE) inhibitors/angiotensin Ⅱ receptor blockers, statins, and cytokine antagonists may play active roles in the prevention and treatment of acute coronary syndrome when used in addition to conventional therapies (glycoprotein Ⅱb/Ⅲa receptor antagonists, mechanical intervention strategies, etc).

  18. Ecstasy-induced acute coronary syndrome: something to rave about.

    Hoggett, Kerry; McCoubrie, David; Fatovich, Daniel M

    2012-06-01

    Ecstasy or 3,4-methylenedioxymethamphetamine is a commonly used illicit recreational drug, enjoying popularity for its stimulant effects. Although acute coronary syndrome is recognized after cocaine and methamphetamine use, association with Ecstasy use has rarely been reported. We report three cases of significantly delayed acute coronary syndrome and ST elevation myocardial infarction related to ingestion of Ecstasy. PMID:22672176

  19. Nuclear Cardiology in Acute Coronary Syndrome

    Paeng, Jin Chul; Lee, Dong Soo [Seoul National University College of Medicine, Seoul (Korea, Republic of)

    2009-06-15

    Nuclear myocardial perfusion imaging is very effective in the evaluation of patients with suspicious acute coronary syndrome (ACS), for adequate diagnosis and treatment. There have been many clinical evidences to support the efficacy and cost-effectiveness. In addition, many authoritative guidelines support the utility of myocardial perfusion imaging in ACS with an appropriate diagnostic protocol. However, with the development of other cardiac imaging modalities, the choice of modality for the diagnosis of suspicious ACS now depends on the availability of each modality in each institute. Newly developed imaging technologies, especially including molecular imaging, are expected to have great potential not only for diagnosis but also for primary, secondary, and tertiary prevention of ACS.

    2013-05-01

    Acute coronary syndrome (ACS) is a major cause of morbidity and mortality worldwide. New serological biomarkers, such as troponins, have improved the diagnosis of ACS; however, the diagnosis of ACS can still be difficult as there is marked heterogeneity in its presentation and significant overlap with other disorders presenting with chest pain. Evidence is accumulating that cardiac MRI provides information that can aid the detection and differential diagnosis of ACS, guide clinical decision-making and improve risk-stratification after an event. In this review, we present the relevant cardiac MRI techniques that can be used to detect ACS accurately, provide differential diagnosis, identify the sequelae of ACS, and determine prognostication after ACS.

  2. The clinics of acute coronary syndrome.

    Cervellin, Gianfranco; Rastelli, Gianni

    2016-05-01

    Risk stratification and management of patients with chest pain continues to be challenging despite considerable efforts made in the last decades by many clinicians and researchers. The throutful evaluation necessitates that the physicians have a high index of suspicion for acute coronary syndrome (ACS) and always keep in mind the myriad of often subtle and atypical presentations of ischemic heart disease, especially in certain patient populations such as the elderly ones. In this article we aim to review and discuss the available evidence on the value of clinical presentation in patients with a suspected ACS, with special emphasis on history, characteristics of chest pain, associated symptoms, atypical presentations, precipitating and relieving factors, drugs, clinical rules and significance of clinical Gestalt. PMID:27294087

  4. Cardiac computed tomography in patients with acute coronary syndrome

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

  7. Nuclear cardiology in acute coronary syndromes

    Acute coronary syndromes are a frequent manifestation of a coronary artery disease, usually being associated with chest pain and presenting as a medical emergency. Since a considerable number of patients with chest pain, however, have a non cardiac etiology of trier pain, properly triaging these patients represents a diagnostic challenge for physicians in the emergency department. As the available diagnostic procedures have limited accuracy, many different diagnostic strategies have been evaluated. Among these, radionuclide myocardial perfusion imaging (MPI) at rest or in combination with stress procedures has been investigated in many trails. MPI has been proven to be useful, especially in a patient population with a low to intermediate probability of an ischemic event. Perfusion scintigraphy has a high sensitivity in the detection of myocardial infarction and reveals an excellent negative predictive value, allowing a safe discharge strategy of patients with a negative scan result. Moreover, it enables risk stratification and provides incremental and independent prognostic information regarding short to long term future cardiac adverse events. Several cost effectiveness studies have shown that perfusion imaging leads to lower overall direct costs, mainly by a reduction of unnecessary hospital admissions and diagnostic angiograms, without worsening of the clinical outcome of these patients. As a possible study endpoint, myocardial perfusion imaging in the acute setting enables the quantification of salvaged myocardium and therefore the evaluation of treatment efficacy. Besides perfusion agents, several infarcts avid radiopharmaceuticals have been developed, which in part show promising results. However, larger randomized trials evaluating these tracers in clinical settings are needed to warrant routine clinical application

  9. Acute coronary syndromes: an old age problem

    Alexander D Simms; Philip D Batin; John Kurian; Nigel Durham; Christopher P Gale

    2012-01-01

    The increasing population in older age will lead to greater numbers of them presenting with acute coronary syndromes (ACS). This has implications on global healthcare resources and necessitates better management and selection for evidenced-based therapies. The elderly are a high risk group with more significant treatment benefits than younger ACS. Nevertheless, age related inequalities in ACS care are recognised and persist. This discrepancy in care, to some extent, is explained by the higher frequency of atypical and delayed presentations in the elderly, and less diagnostic electrocardiograms at presentation, potentiating a delay in ACS diagnosis. Under estimation of mortality risk in the elderly due to limited consideration for physiological frailty, co-morbidity, cognitive/psychological impairment and physical disability, less input by cardiology specialists and lack of randomised, controlled trials data to guide management in the elderly may further confound the inequality of care. While these inequalities exist, there remains a substantial opportunity to improve age related ACS outcomes. The selection of elderly patients for specific therapies and medication regimens are unanswered. There is a growing need for randomised, controlled trial data to be more representative of the population and enroll those of advanced age with co-morbidity. A lack of reporting of adverse events, such as renal impairment post coronary angiography, in the elderly further limit risk benefit decisions. Substantial improvements in care of elderly ACS patients are required and should be advocated. Ultimately, these improvements are likely to lead to better outcomes post ACS. However, the improvement in outcome is not infinite and will be limited by non-modifiable factors of age-related risk.

  10. Acute Coronary Syndrome: Posthospital Outpatient Management.

    Veauthier, Brian; Sievers, Karlynn; Hornecker, Jaime

    2015-10-01

    When providing care for patients who are discharged from the hospital after experiencing acute coronary syndrome (ACS), several issues should be addressed. Drug regimens should be reviewed to ensure that patients are taking appropriate drugs, including antiplatelet agents, angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers, aldosterone antagonists, beta blockers/calcium channel blockers, cholesterol-lowering drugs, and nitroglycerin. The review also should confirm that patients understand when and how to take their drugs, and that there are no obstacles (eg, cost) that might result in nonadherence to drug regimens. Lifestyle modifications, including improvements in diet and exercise regimens, along with participation in a cardiac rehabilitation program, should be encouraged. Risk factor reduction measures include smoking cessation for smokers, weight management for patients who are overweight, and optimal control of blood pressure and blood glucose levels. Appropriate vaccinations should be administered; influenza and pneumococcal vaccines are indicated for all patients with ACS in the absence of contraindications. Patients requiring pain control should avoid use of nonsteroidal anti-inflammatory drugs because they increase the risk of cardiovascular events; acetaminophen or other drugs should be used. Finally, depression is common among patients with ACS. Screening for and management of depression are significant components of care. PMID:26439396

  13. Acute Coronary Syndrome Due to Spontaneous Coronary Artery Dissection in a Middle-Aged Man

    Davran Cicek

    2014-08-01

    Full Text Available True spontaneous coronary artery dissection (SCAD is an extremely rare but important cause of acute coronary syndrome, with only about 200 cases reported in the literature. Diagnosis is often made at autopsy. Risk factors include oral contraceptive use, atherosclerotic disease and the peripartum period. SCAD should be considered when a healthy young patient presents with the onset of acute myocardial ischemic syndrome. A timely diagnosis and intervention are mandatory as SCAD can cause sudden death. We present a case of SCAD with an uncommon clinical presentation of acute coronary syndrome and without identifiable risk factors, and successfully treated with non-invasive (medical therapy.

    JIA Yu-he; YANG Yue-jin; WEI Yi-zhen; YAO Min; HU Sheng-shou

    2005-01-01

    @@ Coronary artery bypass grafting (CABG) is considered as a more complete means of revascularization than percutaneous coronary intervention (PCI). However, acute coronary syndrome (ACS) can still occur after CABG. The culprit vessel can be the graft vessel or the native vessel. Many questions remain unanswered in the Chinese literature regarding this topic: what are the short- and long-term pathological changes that induce ACS? Is there any difference between arterial and venous grafts with respect to the frequency of restenosis? Are there any patterns of ACS-related vessels in different periods after CABG? We aim to answer these fundamental questions by analyzing coronary angiographies of patients with recurrent ACS following CABG and provide evidence for reducing post-CABG restenosis.

    Full Text Available The incidence of bradyarrhythmias in patients with acute coronary syndrome (ACS is 0.3% to 18%. It is caused by sinus node dysfunction (SND, high-degree atrioventricular (AV block, or bundle branch blocks. SND presents as sinus bradycardia or sinus arrest. First-degree AV block occurs in 4% to 13% of patients with ACS and is caused by rhythm disturbances in the atrium, AV node, bundle of His, or the Tawara system. First- or second-degree AV block is seen very frequently within 24 h of the beginning of ACS; these arrhythmias are frequently transient and usually disappear after 72 h. Third-degree AV blocks are also frequently transient in patients with infero-posterior myocardial infarction (MI and permanent in anterior MI patients. Left anterior fascicular block occurs in 5% of ACS; left posterior fascicular block is observed less frequently (incidence < 0.5%. Complete bundle branch block is present in 10% to 15% of ACS patients; right bundle branch block is more common (2/3 than left bundle branch block (1/3. In patients with bradyarrhythmia, intravenous (IV atropine (1-3 mg is helpful in 70% to 80% of ACS patients and will lead to an increased heart rate. The need for pacemaker stimulation (PS is different in patients with inferior MI (IMI and anterior MI (AMI. Whereas bradyarrhythmias are frequently transient in patients with IMI and therefore do not need permanent PS, there is usually a need for permanent PS in patients with AMI. In these patients bradyarrhythmias are mainly caused by septal necrosis. In patients with ACS and ventricular arrhythmias (VTA amiodarone is the drug of choice; this drug is highly effective even in patients with defibrillation-resistant out-of-hospital cardiac arrest. There is general agreement that defibrillation and advanced life support is essential and is the treatment of choice for patients with ventricular flutter/fibrillation. If defibrillation is not available in patients with cardiac arrest due to VTA

  18. Imaging Techniques in Acute Coronary Syndromes: A Review

    2011-01-01

    Coronary heart disease (CHD) remains the leading cause of death in the United States. National review of Emergency Department (ED) visits from 2007 to 2008 reveals that 9% are for chest pain. Of these patients, 13% had acute coronary syndromes (ACSs) (Antman et al., 2004). Plaque rupture with thrombus formation is the most frequent cause of ACS, and identifying patients prior to this event remains important for any clinician caring for these patients. There has been an increasing amount of re...

  19. Treatment-Resistant Depression and Mortality after Acute Coronary Syndrome

    Carney, Robert M.; Freedland, Kenneth E

    2009-01-01

    Depression is a risk factor for morbidity and mortality in patients with coronary heart disease (CHD), especially following acute coronary syndrome (ACS). Evidence from recent clinical trials suggests that treatment-resistant depression may be associated with a particularly high risk of mortality or cardiac morbidity in post-ACS patients. This manuscript reviews this evidence, and considers possible explanations for this relationship. Directions for future research are also considered, with p...

    2003-01-01

    Objective: To explore the relationship of Traditional Chinese Medicine (TCM) Syndrome type and coronary arteriography (CAG) with respect to the number and degree of stenosed branches of coronary artery (CA) and ACC/AHA stage of acute coronary syndrome (ACS), to provide an objective evidence for TCM Syndrome typing on ACS.Methods: Ninety patients of ACS with their TCM Syndrome typing and CAG successfully conducted were enrolled in this study. They were classified into 3 Syndrome types, the blood stasis type (typeⅠ), the phlegm stagnant with blood stasis type (typeⅡ), and the endogenous collateral Wind type (typeⅢ). The scores of the number and severity of the stenosis branch of CA and ACC/AHA lesion stage in different Syndrome types were calculated respectively and analysed statistically by Ridit analysis.Results: The number of stenosed branches increased gradually with the Syndrome type changing from Ⅰ→Ⅱ→Ⅲ, compared the type Ⅲ with the other two types(P<0.01). The severity of stenosis in typeⅠ and Ⅱ were similar, but that of Type Ⅲ, much aggravated was significantly different from that in the former two (P<0.01). The ACC/AHA stage of coronary lesion tended to be more complex as the Syndrome type changed, patients of TCM typeⅠ and Ⅱ had mostly lesion of stage A or B1 , while lesion in majority of patients of type Ⅲ belonged to stage B2 or C, comparison between the three types showed significant difference (P<0.01). Conclusion: Most ACS patients of TCM Syndrome type Ⅲ with tri-branch, severe stenosed coronary arteries, belong to the complex ACC/AHA stage of B2 and C.

    Full Text Available Spontaneous coronary artery dissection (SCAD is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50 and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement.

    For patients with a non-ST-segment elevation acute coronary syndrome (NSTE-ACS), guideline recommendations and treatment pathways focus on revascularization for definitive treatment if the patient is an appropriate candidate. Despite the widespread use of revascularization for NSTE-ACS, most patients undergo a percutaneous coronary intervention, whereas a minority of patients undergo coronary artery bypass grafting. Focusing specifically on the USA, the contemporary utilization, preoperative and perioperative considerations, and outcomes of NSTE-ACS patients undergoing coronary artery bypass grafting have not been comprehensively reviewed.

  10. Apical hypertrophic cardiomyopathy presenting as acute coronary syndrome.

    Abdin, Amr; Eitel, Ingo; de Waha, Suzanne; Thiele, Holger

    2016-06-01

    Apical hypertrophic cardiomyopathy is a rare variant of hypertrophic cardiomyopathy. It is characterized by a local hypertrophy of the apical segments and displays typical electrocardiographic and imaging patterns. The clinical manifestations are variable and range from an asymptomatic course to sudden cardiac death. The most frequent symptom is chest pain and thus apical hypertrophic cardiomyopathy can mimic the symptoms and repolarization disturbances indicative of acute coronary syndrome. PMID:26628684

  11. Isolated single coronary artery presenting as acute coronary syndrome: case report and review.

    Mahapatro, Anil K; Patro, A Sarat K; Sujatha, Vipperala; Sinha, Sudhir C

    2014-06-01

    Congenital single coronary artery is commonly associated with complex congenital heart diseases and manifests in infancy or childhood. But isolated single coronary artery is a rare congenital anomaly which can present as acute coronary syndrome in adults. The aim of the work is to discuss on isolated single coronary artery in two adults presenting as acute coronary syndrome. The first case underwent coronary angiography (CAG) through right radial route, but switched over to femoral for confirmation of diagnosis and due to radial spasm. An aortic root angiogram was done to rule out presence of any other coronary ostia. It revealed a single coronary artery originating from right sinus of valsalva. After giving rise to posterior descending artery branch at crux, it continued in the atrioventricular groove to the anterior basal surface of the heart and traversed as anterior descending artery. There was no atheromatous occlusive stenosis. This is R-I type single coronary artery as per Lipton classification. In the second case, angiography was completed through right radial route. It revealed a single coronary artery arising from right aortic sinus. Anterior descending and circumflex branch were originating from proximal common trunk of the single coronary artery and supplying the left side of the heart. The right coronary artery has diffuse atheromatous disease without significant stenosis in any major branch. This is R-III C type as per Lipton classification. A coronary anomaly of both origin and course is very rare. It may be encountered in adults evaluated for atherosclerotic coronary heart disease. Knowledge and understanding of anatomical types of this congenital anomaly will reduce time, anxiety, complications during CAG and cardiac surgery. PMID:25075168

  12. Relationship between coronary artery ectasia, cocaine abuse and acute coronary syndromes

    Dendramis, Gregory; Paleologo, Claudia; Piraino, Davide; Assennato, Pasquale

    2016-01-01

    Coronary artery ectasia (CAE) often represents a coronary angiography finding casually detected or following the occurrence of an acute coronary syndrome. The pathogenetic role of cocaine abuse in the genesis of CAE is still little known and very few data are available in literature. We describe a case of a 31-year-old male cocaine user admitted to our department for typical acute chest pain. Coronary angiography showed diffuse coronary ectasia with slow flows and without hemodynamically significant stenosis. An increasing of matrix metalloproteinases values and a reduction of their tissue inhibitors was showed both during hospitalization and at one month after discharge. This case report emphasizes the close relationship between cocaine abuse, CAE and acute coronary syndromes in patients without hemodynamically significant coronary stenosis. As reported by Satran et al, cocaine abuse should be considered an important risk factor for CAE and these patients appear to be at increased risk of angina and acute myocardial infarct. Further studies that can strengthen this hypothesis would be useful to deepen and better analyze this interesting association. PMID:27231522

    Diffuse coronary arteries ectasia combined with calcification is seldom reported. Acute coronary syndrome, a potentially life-threatening disease, accompanied with coronary ectasia and diffuse calcification, made percutaneous coronary intervention difficult and risky owing to increasing complications rate. Dual-source computed tomography and three-dimensional volume rendering images help cardiovascular surgeon easier to localize the ideal site and facilitate the procedure.

  14. Using machine learning techniques to differentiate acute coronary syndrome

    Sougand Setareh

    2015-02-01

    Full Text Available Backgroud: Acute coronary syndrome (ACS is an unstable and dynamic process that includes unstable angina, ST elevation myocardial infarction, and non-ST elevation myocardial infarction. Despite recent technological advances in early diognosis of ACS, differentiating between different types of coronary diseases in the early hours of admission is controversial. The present study was aimed to accurately differentiate between various coronary events, using machine learning techniques. Such methods, as a subset of artificial intelligence, include algorithms that allow computers to learn and play a major role in treatment decisions. Methods: 1902 patients diagnosed with ACS and admitted to hospital were selected according to Euro Heart Survey on ACS. Patients were classified based on decision tree J48. Bagging aggregation algorithms was implemented to increase the efficiency of algorithm. Results: The performance of classifiers was estimated and compared based on their accuracy computed from confusion matrix. The accuracy rates of decision tree and bagging algorithm were calculated to be 91.74% and 92.53%, respectively. Conclusion: The proposed methods used in this study proved to have the ability to identify various ACS. In addition, using matrix of confusion, an acceptable number of subjects with acute coronary syndrome were identified in each class.

  15. Applications of radionuclide myocardial perfusion imaging in acute coronary syndrome

    In recent years, acute coronary syndrome(ACS) has been getting more and more attentions. Radionuclide myocardial perfusion imaging (MPI) can make a quick accurate diagnosis for patients with acute chest pain who cann't be diagnosed by conventional methods. The sensitivity and negative predictive value of MPI are relatively high. Besides, MPI can be applicated in the detection of ischemic and infarct size and degree, the risk stratification and the assessment of prognosis of the patients with ACS, and the appraisal of the effect of strategies.

  17. Significance of lead aVR in acute coronary syndrome

    Akira; Tamura

    2014-01-01

    The 12-lead electrocardiogram(ECG)is a crucial tool in the diagnosis and risk stratification of acute coronary syndrome(ACS).Unlike other 11 leads,lead aVR has been long neglected until recent years.However,recent investigations have shown that an analysis of ST-segment shift in lead aVR provides useful information on the coronary angiographic anatomy and risk stratification in ACS.ST-segment elevation in lead aVR can be caused by(1)transmural ischemia in the basal part of the interventricular septum caused by impaired coronary blood flow of the first major branch originating from the left anterior descending coronary artery;(2)transmural ischemia in the right ventricular outflow tract caused by impaired coronary blood flow of the large conal branch originating from the right coronary artery;and(3)reciprocal changes opposite to ischemic or non-ischemic ST-segment depression in the lateral limb and precordial leads.On the other hand,ST-segment depression in lead aVR can be caused by transmural ischemia in the inferolateral and apical regions.It has been recently shown that an analysis of T wave in lead aVR also provides useful prognostic information in the general population and patients with prior myocardial infarction.Cardiologists should pay more attention to the tracing of lead aVR when interpreting the12-lead ECG in clinical practice.

  18. Noninvasive Coronary Angiography with 64-Channel Multidetector Computed Tomography in Patients with Acute Coronary Syndrome

    2008-12-15

    Background: Advances in computer tomography (CT) imaging technology in recent years have facilitated the possibility of noninvasive coronary angiography. Purpose: To compare the diagnostic accuracy of 64-channel multidetector computed tomography (MDCT) with conventional invasive coronary angiography (ICA) for the detection of significant coronary stenosis in patients with acute coronary syndrome (ACS). Material and Methods: MDCT was performed in 60 patients classified with non-ST-elevation infarction (NSTEMI) or unstable angina and scheduled for ICA within 3 days. The diagnostic accuracy of MDCT was evaluated using quantitative coronary angiography (QCA) as the gold standard. Results: 48 out of 60 patients had interpretable scans by both MDCT and ICA. On a segment-based analysis, 488 out of 665 segments with a diameter of =1.5 mm, as defined by QCA, were interpretable by MDCT. Sensitivity was 78%, specificity 87%, positive predictive value 47%, and negative predictive value 97% in detecting and excluding significant coronary stenosis, as defined with MDCT. On a per patient-based analysis, sensitivity was 89%, specificity 50%, positive predictive value 84%, and negative predictive value 60%. Conclusion: Limited diagnostic accuracy restricts the usefulness of coronary MDCT in patient groups with a high pretest probability of disease, such as in acute coronary syndrome.

  1. Fractional flow reserve in acute coronary syndromes: A review

    Nikunj R. Shah

    2014-12-01

    Full Text Available Fractional flow reserve (FFR assessment provides anatomical and physiological information that is often used to tailor treatment strategies in coronary artery disease. Whilst robust data validates FFR use in stable ischaemic heart disease, its use in acute coronary syndromes (ACS is less well investigated. We critically review the current data surrounding FFR use across the spectrum of ACS including culprit and non-culprit artery analysis. With adenosine being conventionally used to induce maximal hyperaemia during FFR assessment, co-existent clinical conditions may preclude its use during acute myocardial infarction. Therefore, we include a current review of instantaneous wave free ratio as a novel vasodilator independent method of assessing lesion severity as an alternative strategy to guide revascularisation in ACS.

    Objective: To study the prognostic risk factors of male patients with coronary heart disease in stent placement era. Methods: One hundred and four patients were enrolled in this study (aged 64.9 ± 9.6 years) including 61 diagnosed as acute myocardial infarction, and 43 as unstable angina with followed up 11.9 ± 8.7 months. All factors including demographic factors, non-interventional work-up, associated clinical complications and results of coronary artery angiography reached a model of Logistic regression analysis. Results: Based on MACE (major adverse cardiac events), as quantitative factors, diseased proximal middle left anterior descending artery was a significant independent variable (P<0.05), and its coefficient was 22.00. Conclusions: Diseased proximal middle left anterior descending coronary artery is the prognostic factor of MACE in male patients with acute coronary syndrome. (authors)

    2014-01-01

    A 43-year-old woman having significant risk factors for ischaemic heart disease was admitted with an acute coronary syndrome (ACS). Coronary angiography revealed a non-flow limiting lesion in her right coronary artery with the rest of her arteries unremarkable. Risk stratification of the culprit lesion in the right coronary artery through intravascular ultrasound virtual histology demonstrated that the rupture plaque had less than 5% necrotic core with low vulnerability indices. This important finding suggested that the re-rupture risk was low so aggressive pharmacological treatment that can influence the plaque characteristics was instigated in preference to mechanical plaque sealing with a coronary stent. At a year of follow-up the patient was well and had no further events. PMID:24477714

  7. Multiple Chronic Conditions in Older Adults with Acute Coronary Syndromes.

    Alfredsson, Joakim; Alexander, Karen P

    2016-05-01

    Older adults presenting with acute coronary syndromes (ACSs) often have multiple chronic conditions (MCCs). In addition to traditional cardiovascular (CV) risk factors (ie, hypertension, hyperlipidemia, and diabetes), common CV comorbidities include heart failure, stroke, and atrial fibrillation, whereas prevalent non-CV comorbidities include chronic kidney disease, anemia, depression, and chronic obstructive pulmonary disease. The presence of MCCs affects the presentation (eg, increased frequency of type 2 myocardial infarctions [MIs]), clinical course, and prognosis of ACS in older adults. In general, higher comorbidity burden increases mortality following MI, reduces utilization of ACS treatments, and increases the importance of developing individualized treatment plans.

    The medical management of acute coronary syndrome (ACS) follows the recommendations of international medical societies. The call to the emergency services by the patient triggers a race against the clock in pre-hospital care. It is essential to reduce the duration of the inadequate perfusion of the heart in order to limit its consequences. An effective reperfusion strategy must be planned in advance taking into account the logistical constraints. It is crucial that the general public is educated to recognise the signs of ACS and to call the emergency services immediately (such as 15, 112 or 991). PMID:26040140

    Background Acute coronary syndromes (ACS) have been associated with lower health utilities (HUs) compared with the general population. Given the prognostic improvements after ACS with the implementation of coronary angiography (eg, percutaneous coronary intervention (PCI)), contemporary HU values derived from patient-reported outcomes are needed. Methods We analysed data of 1882 patients with ACS 1 year after coronary angiography in a Swiss prospective cohort. We used the EuroQol five-dimensional questionnaire (EQ-5D) and visual analogue scale (VAS) to derive HU indexes. We estimated the effects of clinical factors on HU using a linear regression model and compared the observed HU with the average values of individuals of the same sex and age in the general population. Results Mean EQ-5D HU 1-year after coronary angiography for ACS was 0.82 (±0.16) and mean VAS was 0.77 (±0.18); 40.9% of participants exhibited the highest utility values. Compared with population controls, the mean EQ-5D HU was similar (expected mean 0.82, p=0.58) in patients with ACS, but the mean VAS was slightly lower (expected mean 0.79, p<0.001). Patients with ACS who are younger than 60 years had lower HU than the general population (<0.001). In patients with ACS, significant differences were found according to the gender, education and employment status, diabetes, obesity, heart failure, recurrent ischaemic or incident bleeding event and participation in cardiac rehabilitation (p<0.01). Conclusions At 1 year, patients with ACS with coronary angiography had HU indexes similar to a control population. Subgroup analyses based on patients' characteristics and further disease-specific instruments could provide better sensitivity for detecting smaller variations in health-related quality of life.

    Full Text Available Background: Abdominal obesity is an important cardiovascular risk factor. Therefore, identifying the best method for measuring waist circumference (WC is a priority. Objective: To evaluate the eight methods of measuring WC in patients with acute coronary syndrome (ACS as a predictor of cardiovascular complications during hospitalization. Methods: Prospective study of patients with ACS. The measurement of WC was performed by eight known methods: midpoint between the last rib and the iliac crest (1, point of minimum circumference (2; immediately above the iliac crest (3, umbilicus (4, one inch above the umbilicus (5, one centimeter above the umbilicus (6, smallest rib and (7 the point of greatest circumference around the waist (8. Complications included: angina, arrhythmia, heart failure, cardiogenic shock, hypotension, pericarditis and death. Logistic regression tests were used for predictive factors. Results: A total of 55 patients were evaluated. During the hospitalization period, which corresponded on average to seven days, 37 (67% patients had complications, with the exception of death, which was not observed in any of the cases. Of these complications, the only one that was associated with WC was angina, and with every cm of WC increase, the risk for angina increased from 7.5 to 9.9%, depending on the measurement site. It is noteworthy the fact that there was no difference between the different methods of measuring WC as a predictor of angina. Conclusion: The eight methods of measuring WC are also predictors of recurrent angina after acute coronary syndromes.

  16. Update: acute coronary syndromes (VI): treatment of acute coronary syndromes in the elderly and in patients with comorbidities.

    Savonitto, Stefano; Morici, Nuccia; De Servi, Stefano

    2014-07-01

    Acute coronary syndromes have a wide spectrum of clinical presentations and risk of adverse outcomes. A distinction should be made between treatable (extent of ischemia, severity of coronary disease and acute hemodynamic deterioration) and untreatable risk (advanced age, prior myocardial damage, chronic kidney dysfunction, other comorbidities). Most of the patients with "untreatable" risk have been excluded from the "guideline-generating" clinical trials. In recent years, despite the paucity of specific randomized trials, major advances have been completed in the management of elderly patients and patients with comorbidities: from therapeutic nihilism to careful titration of antithrombotic agents, a shift toward the radial approach to percutaneous coronary interventions, and also to less-invasive cardiac surgery. Further advances should be expected from the development of drug regimens suitable for use in the elderly and in patients with renal dysfunction, from a systematic multidisciplinary approach to the management of patents with diabetes mellitus and anemia, and from the courage to undertake randomized trials involving these high-risk populations.

  17. Ticagrelor: A new antiplatelet drug for acute coronary syndromes

    Tirtha V Patel

    2013-01-01

    Full Text Available Coronary heart disease and acute coronary syndrome (ACS are a significant cause of morbidity and mortality all over the world. Antiplatelet agents play an essential role in the treatment of acute coronary syndrome (ACS, usually with aspirin and a thienopyridine. Currently, clopidogrel, a second generation thienopyridine, is the main drug of choice, and the combination of aspirin and clopidogrel is administered orally for the treatment of ACS. Clopidogrel, the most commonly used thienopyridine, is limited by a high degree of interpatient variability and inconsistent inhibition of platelets. Ticagrelor, a new, oral, direct-acting P2Y12 receptor antagonist, produces a more profound and consistent antiplatelet effect than clopidogrel. The U.S. Food and Drug Administration approved Ticagrelor on July 20, 2011. Furthermore, ticagrelor has at least one active metabolite, which has pharmacokinetics that are very similar to the parent compound. Therefore, ticagrelor has a more rapid onset and more pronounced platelet inhibition than other antiplatelet agents. The safety and efficacy of ticagrelor compared with clopidogrel, in an ACS patient, has been recently evaluated by the PLATelet inhibition and patient Outcomes (PLATO trial. Clinical studies of patients with both ST-elevation and non-ST-elevation ACS have shown that ticagrelor, when compared with clopidogrel, reduces the rates of vascular death and myocardial infarction. The clinical data currently available indicate that ticagrelor is a promising option for the treatment of patients with ACS and may be of particular use in those at high risk for ischemic events or in those unresponsive to clopidogrel.

    Drug-induced type I hypersensitivity reactions are frequent. Sometimes, acute coronary syndrome (ACS) can be registered in such patients, which may have a serious impact on the course and management of the allergic reaction. Because of potentially atypical ACS clinical presentations, the ECG is an obligatory diagnostic tool in any allergic reaction. Coronary artery spasm is the pathophysiological basis of ACS, triggered by the action of potent vasoactive mediators (histamine, neutral protease...

    Full Text Available Metabolic Syndrome (MS or insulin resistance syndrome is commonly defined as a group of risk factors or abnormalities associated with insulin resistance that markedly increased risk for both coronary heart disease and diabetes. Cardiovascular disease and all-cause mortality, even in the absence of baseline CVD and diabetes. Early identification, treatment and prevention of the metabolic syndrome present a major challenge for health care professionals facing an epidemic of overweight and sedentary lifestyle. AIMS AND OBJECTIVES To study the prevalence of metabolic syndrome in pts. with Acute Coronary Syndrome (ACS and its effect on hospital outcomes. MATERIALS AND METHODS Observational study in 55 cases (28 cases and 27 controls was conducted in Dr. BRAMH, Raipur and each patient was assessed with detailed clinical history and was also assessed for parameters of MS. The cases and controls were also followed up during their hospital stay for the presence of or development of heart failure, arrhythmias, shock and death. Chi square and ‘t’ test were used to analyse obtained data. RESULTS AND CONCLUSIONS In the present study sex ratio amongst the cases was (M:F 1.15:1 and 2.6:1 in controls. Maximum patients were between the ages of 50-60. Non-ST elevation MI was more common in patients with metabolic syndrome and they presented late to the hospital for treatment. Hypertension and fasting hyperglycemia are the most prevalent components of metabolic syndrome in patients of acute coronary syndrome. Our Study also suggests that hypertriglyceridemia is the most common lipid abnormality in patients of acute coronary syndrome. An increase in the incidence of heart failure was observed in patients with metabolic syndrome Cardiogenic shock is seen with increased frequency in patients with metabolic syndrome. Case fatalities were seen with equal frequency in both the groups, hence metabolic syndrome is not associated with increased case fatality while

    Increasing evidence supports a link between serological evidence of prior exposure to infectious pathogens, pathogen burden, and the risk for future myocardial infarction and death in patients with coronary artery disease. Based on this concept, we evaluated the intimal presence of four pathogens in human coronary atheroma, clinically associated with acute coronary syndromes (ACS) and stable angina (SA), and the effect of pathogen burden on the expression of human heatshock protein 60 (hHSP60), a key protein in (auto-)immune pathogenesis of atherosclerosis. Coronary atherectomy specimens retrieved from 53 primary target lesions of patients with ACS (n=33) or SA (n=20) were assessed immunohistochemically for the presence of Chlamydia pneumoniae (C. pn.), Helicobacter pylori (H.p.), Cytomegalovirus (CMV) and Epstein-Barr Virus (EBV), and for the expression of hHSP60. Chlamydia pneumoniae was present in 74%, Helicobacter pylori in 32%, CMV in 13% and EBV in 42%. Exclusively C.pn. revealed a prevalence in ACS (91%) vs SA (45%; p<0.001). Immunohistochemical analysis revealed 6 lesions without, 21 lesions with 1, 17 lesions with 2, 6 lesions with 3 and 3 lesions with 4 infectious agents. As an important finding, the mean value in ACS lesions was significantly increased compared to those in SA (1.9 vs 1.1; p<0.01). ACS-subgroup analysis revealed the highest mean value in patients with pain at rest within the last two days (Braunwald class III). In addition, expression of hHSP60 was significantly higher in ACS (8.7%) compared to SA (1.3%; p<0.001). Pathogen burden correlated highly significant (p<0.01) with the expression of hHSP60 (r=0.44).Our data demonstrate the impact of intimal pathogen burden in plaque instability, and suggest the presence of (auto-)immunoreactions against upregulated hHSP60 as an important pathomechanism that may contribute to acute coronary syndromes.

    2013-01-01

    Full Text Available Trastuzumab is a monoclonal antibody highly effective in the treatment of several cancers, but its use is associated with cardiac toxicity which usually responds to cessation of the drug and/or medical therapy. We present an unusual case of acute cardiac toxicity temporally related to administration of trastuzumab in which the clinical presentation suggested an acute coronary syndrome. Coronary angiography, however, demonstrated minimal epicardial disease, but new wall motion abnormalities. Furthermore, the patient did not respond to withdrawal of the drug or medical therapy for heart failure.

  4. Comparison of prasugrel and clopidogrel in patients with acute coronary syndrome undergoing percutaneous coronary intervention

    Full Text Available Nicholas B Norgard,1 Mazen Abu-Fadel21University at Buffalo, School of Pharmacy and Pharmaceutical Sciences, Buffalo, NY, USA; 2University of Oklahoma Health Sciences Center, Cardiovascular Section, Oklahoma City, OK, USAAbstract: Antiplatelet agents are the cornerstone of treatment for patients with acute coronary syndrome (ACS undergoing percutaneous coronary intervention (PCI. Clopidogrel, when added to aspirin, has demonstrated considerable success at reducing thrombotic complications of ACS and/or PCI compared to aspirin alone and is standard of care for the management of patients with ACS and in patients undergoing PCI. Prasugrel is a novel thienopyridine antiplatelet agent recently approved for the treatment of patients with ACS undergoing PCI. Prasugrel provides greater and more consistent platelet inhibition than clopidogrel due to earlier and more extensive formation of its active metabolite. The enhanced platelet inhibition with prasugrel led to a reduction in major adverse cardiovascular events in patients with moderate to high risk ACS scheduled for PCI in the phase 3 TRITON-TIMI 38 trial. This benefit was seen more in patients suffering a STEMI and those with diabetes. However, this reduction in events was met with a significant increase in the risk of bleeding which overcame prasugrel’s benefit in certain groups. Future studies with prasugrel are needed to determine its optimal utilization to minimize bleeding risks and evaluate its outcomes in ACS and safety profile in special patient populations.Keywords: clopidogrel, prasugrel, percutaneous coronary intervention, acute coronary syndrome

    We decided to assess the prognostic value of NLRP3 inflammasome level in acute coronary syndrome (ACS) patients and whether it was related to coronary atherosclerotic severity. Study population included one-hundred and twenty-three (123) subjects. Peripheral blood monocyte NLRP3 protein level was correlated with clinical presentation, angiographic characteristics and its scoring systems as well as GRACE and TIMI risk scores. Follow-up for major adverse cardiac events (MACE) was carried out at 180 days. Peripheral blood monocyte NLRP3 was found to be elevated in ACS patients (P operating characteristic curves for NLRP3 showed good predictive value for MACE. There is a positive correlation of NLRP3 level with severity of coronary atherosclerosis. NLRP3 level is a promising prognostic utility and is efficient in event prediction for MACE. PMID:26290166

  7. Acute Coronary Syndromes: From The Laboratory Markers To The Coronary Vessels

    Palazzuoli Alberto

    2006-01-01

    Full Text Available A number of "interesting" risk markers have been proposed as providing prognostic information in acute coronary syndromes (ACS. Elevation in plasma inflammatory and necrosis biomarkers have been related to future cardiovascular events in individuals with or without prior myocardial infarction. Recently BNP and pro-BNP are entered in clinical practice to recognize patients at major risk, providing incremental information respect to the traditional markers. Together with these laboratory indexes, a few of promising laboratory markers once easily available, could become useful in identification of patients at high risk. Several studies evaluated many markers of platelet aggregation, endothelial dysfunction and vascular thrombosis, but it is not yet clear whether each of the proposed markers may provide incremental predictive information. We describe, following the most studies reported in literature, the laboratory markers with potential clinical and prognostic power that could early help physicians in the identifi cation of patients with impaired coronary disease and more narrowed coronary arteries.

    New biomarkers of cardiovascular disease are needed to augment the information obtained from traditional indicators and to illuminate disease mechanisms. One of the approaches used in metabolomics/metabonomics for that purpose is metabolic fingerprinting aiming to profile large numbers of chemically diverse metabolites in an essentially nonselective way. In this study, gas chromatography-mass spectrometry was employed to evaluate the major metabolic changes in low molecular weight plasma metabolites of patients with acute coronary syndrome (n = 9) and with stable atherosclerosis (n = 10) vs healthy subjects without significant differences in age and sex (n = 10). Reproducible differences between cases and controls were obtained with pattern recognition techniques, and metabolites accounting for higher weight in the classification have been identified through their mass spectra. On this basis, it seems inherently plausible that even a simple metabolite profile might be able to offer improved clinical diagnosis and prognosis, but in addition, specific markers are being identified.

    2011-01-01

    Full Text Available Arterial chronic hypertension (HTN is a well-known cardiovascular risk factor for development of atherosclerosis. In order to explain the relation between HTN and acute coronary syndromes the following factors should be considered: (1 risk factors are shared by the diseases, such as genetic risk, insulin resistance, sympathetic hyperactivity, and vasoactive substances (i.e., angiotensin II; (2 hypertension is associated with the development of atherosclerosis (which in turn contributes to progression of myocardial infarction. From all the registries and the data available up to now, hypertensive patients with ACS are more likely to be older, female, of nonwhite ethnicity, and having a higher prevalence of comorbidities. Data on the prognostic role of a preexisting hypertensive state in ACS patients are so far contrasting. The aim of the present paper is to focus on hypertensive patients with ACS, in order to better elucidate whether these patients are at higher risk and deserve a tailored approach for management and followup.

  11. Agranulocytosis and acute coronary syndrom in apathetic hyperthyreoidism

    Ivović Miomira

    2003-01-01

    disorder in hyperthyroidism but paroxysmal tachycardia and atrial fibrillation are not rare. This can be explained by increased heart rate, cardiac output, blood volume, coronary artery flow and peripheral oxygen consumption in thyreotoxicosis [9]. Patients with coronary arteriosclerosis can develop angina pectoris during thyreotoxic stage, which can be explained by imbalance between cardiac demand and supply. Myocardial damage is often in thyrotoxic patients with chronic hart failure, together with myocardial infarction in patients without coronary disease [2,6]. Congestive heart failure and atrial fibrillation are relatively resistant to digitalis treatment because of high metabolic turn over of medication and excessive myocardial irritability in hyperthyro-idism [6]. Cardiovascular and myopathic manifestations predominate in older hyperthyroid patients (over 60 years and some of them can have only few symptoms of hyperthyroidism [1-3]. Thyrotoxic state characterized by fatigue, apathy, extreme weakness, low-grade fever and sometimes congestive heart failure are designated as apathetic hyperthyroidism. Such patients have small goiters, mild tachycardia and often cool and dry skin with few eye signs [6]. Patients with subclinical hyperthyroidism are at increased risk for atrial fibrillation [9]. Unstable angina and non-Q myocardial infarction (non ST elevation are acute manifestation of coronary artery disease. The acute coronary syndrome of unstable angina, non-Q myocardial infarction and Q-wave myocardial infarction have atherosclerotic lesions of the coronary arteries as a common pathogenic substrate. Errosions or ruptures of unstable atherosclerotic plaque triggered pathophysiologic processes, resulted in thrombus formation at the site of arterial injury. This leads to abrupt reduction or cessation through the affected vessel. Clinical manifestations of unstable angina and non-Q myocardial infarction are similar and diagnosis of non-Q myocardial infarction is made on

    Full Text Available Coronary Artery Disease (CAD is becoming a major cause of morbidity & mortality burden in the developing world. Indians have been associated with a more severe form of CAD that has its onset at a younger age group with a male predominance. A prospective study was carried out to identify the risk factors and to know the emerging clinical profile in acute coronary syndrome (ACS including S T elevation & Non S T elevation myocardial infarction. We enrolled 200 consecutive patients with typical ECG changes & clinical history, admitted in emergency department from January 2009 to December 2009. A predefined Performa was completed in every patient with a detailed clinical history, physical examinations, and investigation studies. The clinical history revealed information about age, gender, risk factors, and modes of presentation and duration of symptoms. The details of physical examination including anthropometric data, vital signs and complete systemic evaluation were recorded. The regions of infarction and rhythm disturbances were also documented. Our study showed a significant male predominance with mean age being 56 years. Tobacco was identified as major risk factors (65% & obesity (BMI more than 25 is least common risk factor (13%.Patients had typical chest pain (94% and ECG showed anterior wall changes in54%. Forty percent patients developed complications, majority being arrhythmias (60% and least common is mechanical complication (2.5% Thus we conclude that ACS is more common in adult male with tobacco being major risk factors in our population.

  13. Imaging Techniques in Acute Coronary Syndromes: A Review

    Zimmerman, Stanley K.; Vacek, James L.

    2011-01-01

    Coronary heart disease (CHD) remains the leading cause of death in the United States. National review of Emergency Department (ED) visits from 2007 to 2008 reveals that 9% are for chest pain. Of these patients, 13% had acute coronary syndromes (ACSs) (Antman et al., 2004). Plaque rupture with thrombus formation is the most frequent cause of ACS, and identifying patients prior to this event remains important for any clinician caring for these patients. There has been an increasing amount of research and technological advancement in improving the diagnosis of patients presenting with ACS. Low-to-intermediate risk patients are the subgroup that has a delay in definitive treatment for ACS, and a push for methods to more easily and accurately identify the patients within this group that would benefit from an early invasive strategy has arisen. Multiple imaging modalities have been studied regarding the ability to detect ischemia or wall motion abnormalities (WMAs), and an understanding of some of the currently available noninvasive and invasive imaging techniques is important for any clinician caring for ACS patients.

    Currently, cardiac computed tomography (CT) is increasingly being implemented into clinical algorithms, primarily due to substantial technical advances over the last decade. Its use in the setting of suspected acute coronary syndrome is of particular relevance, given the high degree of accumulating scientific evidence of improving patient outcomes. Performing cardiac CT requires specific knowledge on the available scan acquisitions and patient preparation. Also, expertise is required in order to interpret the coronary and extra-coronary findings adequately. The present article provides an overview of the different aspects on the use of cardiac CT in the setting of acute coronary syndrome.

  17. Determinants to optimize response to clopidogrel in acute coronary syndrome

    2010-04-01

    Full Text Available Betti Giusti, Anna Maria Gori, Rossella Marcucci, Claudia Saracini, Anna Vestrini, Rosanna AbbateDepartment of Medical and Surgical Critical Care, University of Florence, SOD Atherothrombotic Diseases, AOU Careggi, Florence, ItalyAbstract: The inhibition of platelet function by antiplatelet therapy determines the improvement of the survival of patients with clinically evident cardiovascular disease. Clopidogrel in combination with aspirin is the recommended standard of care for reducing the occurrence of cardiovascular events in patients with acute coronary syndromes undergoing percutaneous coronary intervention. However, major adverse cardiovascular events including stent thrombosis occur in patients taking clopidogrel and aspirin. A growing body of evidence demonstrates that high post-treatment platelet reactivity on antiplatelet treatment is associated with increased risk of adverse clinical events. Clopidogrel requires conversion to active metabolite by cytochrome P450 isoenzymes. The active metabolite inhibits ADP-stimulated platelet activation by irreversibly binding to P2Y12 receptors. Recently, the loss-of-function CYP2C19*2 allele has been associated with decreased metabolization of clopidogrel, poor antiaggregant effect, and increased cardiovascular events. In high risk vascular patients, the CYP2C19*2 polymorphism is a strong predictor of adverse cardiovascular events and particularly of stent thrombosis. Prospective studies evaluating if an antiplatelet treatment tailored on individual characteristics of patients, CYP2C19*2 genotypes, platelet phenotype, drug–drug interaction, as well as traditional and procedural risk factors, are now urgently needed for the identification of therapeutic strategies providing the best benefit for the single subject.Keywords: antiplatelet therapy, clopidogrel, cytochrome P450 2C19 loss-of-function polymorphism, major adverse cardiovascular events, percutaneous coronary interventions

    Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P 0.05). Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

  20. Contribution of inhibitory receptor glycoprotein iib / iiia in coronary angioplasty and acute coronary syndrome, about 152 patients

    The aim of our study was to evaluate the immediate results and long-term intake of anti-GP IIb / IIIa inhibitors for patients with acute coronary syndrome treated with coronary angioplasty. The use of anti-GP IIb / IIIa is a valid therapeutic option in patients with acute coronary syndrome with signs of severity and for patients undergoing complex angioplasty. Adverse effects of anti-GP IIb / IIIa can be seen to encourage vigilance and careful monitoring during the administration of these molecules and perfect knowledge of their pharmacological properties for appropriate use.

    Full Text Available Aim. To compare effect of percutaneous balloon angioplasty (PCA and a systemic thrombolysis (STL on the central and intracardiac hemodynamics in patients with acute coronary syndrome (ACS with ST segment elevation.Material and methods. 80 patients with ACS with ST segment elevation were included in the study. Patients were split into 2 groups depending on reperfusion strategy. PCA was performed in 55 patients (first group. 25 patients of the second group had STL with Streptokinase, i/v, 1 500 000 units per hour. Echocardiography was performed in all patients at admission and after 3 and 7 days of treatment to evaluate intracardiac hemodynamics.Results. Both reperfusion methods significantly increase of ejection fraction (EF and maximal output speed of left ventricle (LV. Increase of LV EF in patients after PCA was higher than this in patients after STL. PCA improved LV diastolic function; STL did not change this characteristic. After PCA working diagnosis of ACS was transformed to the following final diagnosis: acute myocardial infarction (AMI with Q, AMI without Q and unstable angina in 37,5, 30,4 and 32,1% of patients, respectively. After STL diagnosis of AMI with Q was defined in all patients.Conclusion. PCA in patients with ACS with ST segment elevation results in fast improvement of global systolic and diastolic LV function. Besides, PCA prevents AMI with Q in a half of these patients.

Objective: Compare ACS-related length of stay (LOS, total admission cost, and total admission cost by day of discharge/death for patients who died during an inpatient admission with a matched cohort discharged alive following an ACS-related inpatient stay. Methods: Medical and pharmacy claims (2009–2012 were used to identify admissions with a primary diagnosis of ACS from patients with at least 6 months of continuous enrollment prior to an ACS admission. Patients who died during their ACS admission (deceased cohort were matched (one-to-one to those who survived (survived cohort on age, sex, year of admission, Chronic Condition Index score, and prior revascularization. Mean LOS, total admission cost, and total admission cost by the day of discharge/death for the deceased cohort were compared with the survived cohort. A generalized linear model with log transformation was used to estimate the differences in the total expected incremental cost of an ACS admission and by the day of discharge/death between cohorts. A negative binomial model was used to estimate differences in the LOS between the two cohorts. Costs were inflated to 2013 dollars. Results: A total of 1,320 ACS claims from patients who died (n=1,320 were identified and matched to 1,319 claims from the survived patients (n=1,319.

  6. Variation in Admission Rates of Acute Coronary Syndrome Patients in Coronary Care Unit According to Different Seasons

    Objective:Environmental stresses, especially extreme cold and hot weathers, have tendency to have more admissions for acute coronary syndromes. Due to scarcity of local data, we studied the variation in patient admission rates with acute coronary syndrome according to different seasons. Study Design: Descriptive study. Place and Duration of Study: Coronary Care Unit, Civil Hospital and Pakistan Steel Hospital, Karachi, from January 2011 to December 2011. Methodology: The study group comprised consecutive patients with acute coronary syndrome (unstable angina, Non ST-Elevation Myocardial Infarction (NSTEMI), ST-Elevation Myocardial Infarction (STEMI) admitted to the coronary care unit. Patients with stable angina and valvular heart disease were excluded. Data was analyzed for admission according to different seasons, (winter, spring, summer and autumn). Results: The mean age of the 428 cases was 48.5 ± 10.4 years (range 27 to 73 years). Among the study group, 261 (61%) and 167 (39%) cases were male and female respectively. ST-elevation myocardial infarction, non ST-elevation myocardial infarction and unstable angina were present in 206 (48%), 128 (30%) and 94 (22%) respectively. Among the 428 patients, 184 (43%) cases had hypertension, 133 (31%) cases were smokers, 103 (24%) cases had dyslipidemia and diabetes mellitus and 08 (2%) cases had history of premature coronary artery disease. The number of patients admissions with acute coronary syndrome tended to change with sudden change in season. It increased in Winter 158 (36.9%) and Summer 130 (30.3%) in comparison to Spring 80 (18.69%) and Autumn 60 (14.02%) season. Conclusion: It was found variation in admission rates of acute coronary syndrome patients according to different seasons. The number of admissions not only increased in the cold season (winter) but also in hot season (summer) with sudden changes in temperature. (author)

    2016-04-01

    Acute coronary syndrome (ACS) is a serious condition arising from an imbalance of supply and demand to meet myocardium's metabolic needs. Patients typically present with retrosternal chest pain radiating to neck and left arm. Electrocardiography (ECG) and laboratory tests are used indiagnosis. However in emergency departments, there are some difficulties for physicians to decide whether hospitalizing, following up or discharging the patient. The aim of the study is to diagnose ACS and helping the physician with his decisionto discharge or to hospitalizevia machine learning techniques such as support vector machine (SVM) by using patient data including age, sex, risk factors, and cardiac enzymes (CK-MB, Troponin I) of patients presenting to emergency department with chest pain. Clinical, laboratory, and imaging data of 228 patients presenting to emergency department with chest pain were reviewedand the performance of support vector machine. Four different methods (Support vector machine (SVM), Artificial neural network (ANN), Naïve Bayes and Logistic Regression) were tested and the results of SVM which has the highest accuracy is reported. Among 228 patients aged 19 to 91 years who were included in the study, 99 (43.4 %) were qualified as ACS, while 129 (56.5 %) had no ACS. The classification model using SVM attained a 99.13 % classification success. The present study showed a 99.13 % classification success for ACS diagnosis attained by Support Vector Machine. This study showed that machine learning techniques may help emergency department staff make decisions by rapidly producing relevant data. PMID:26815338

    We report 2 patients in whom transient marked QT prolongation occurred after successful emergent percutaneous coronary intervention (PCI) for acute coronary syndrome. One patient developed torsades de pointes. In both cases, the QT interval became markedly prolonged within 24 hours after PCI, and this prolongation persisted for 4 days. The T waves had a giant and bizarre negative shape with a prolonged T-wave peak to T-wave end interval. No new-onset ischemia or congenital long QT syndrome was related to the episodes. The patients had not taken any drugs that could have prolonged the QT interval, and their serum potassium levels were within normal limits. Torsades de pointes following successful PCI for acute coronary syndrome is uncommon, but acquired long QT syndrome should be considered and treated in patients in whom giant and bizarre negative T waves and QT prolongation develop after PCI.

  12. Impact of coronary dominance on in-hospital outcomes after percutaneous coronary intervention in patients with acute coronary syndrome.

    Toshiki Kuno

    Full Text Available OBJECTIVE: This study evaluated the manner in which coronary dominance affects in-hospital outcomes of acute coronary syndrome (ACS patients undergoing percutaneous coronary intervention (PCI. BACKGROUND: Previous studies have shown that left dominant coronary anatomies are associated with worse prognoses in patients with coronary artery disease. METHODS: Data were analyzed from 4873 ACS patients undergoing PCI between September 2008 and April 2013 at 14 hospitals participating in the Japanese Cardiovascular Database Registry. The patients were grouped based on diagnostic coronary angiograms performed prior to PCI; those with right- or co-dominant anatomy (RD group and those with left-dominant anatomy (LD group. RESULTS: The average patient age was 67.6±11.8 years and both patient groups had similar ages, coronary risk factors, comorbidities, and prior histories. The numbers of patients presenting with symptoms of heart failure, cardiogenic shock, or cardiopulmonary arrest were significantly higher in the LD group than in the RD group (heart failure: 650 RD patients [14.7%] vs. 87 LD patients [18.8%], P = 0.025; cardiogenic shock: 322 RD patients [7.3%] vs. 48 LD patients [10.3%], P = 0.021; and cardiopulmonary arrest: 197 RD patients [4.5%] vs. 36 LD patients [7.8%], P = 0.003. In-hospital mortality was significantly higher among LD patients than among RD patients (182 RD patients [4.1%] vs. 36 LD patients [7.8%], P = 0.001. Multivariate logistic regression analysis revealed that LD anatomy was an independent predictor for in-hospital mortality (odds ratio, 1.75; 95% confidence interval, 1.06-2.89; P = 0.030. CONCLUSION: Among ACS patients who underwent PCI, LD patients had significantly worse in-hospital outcomes compared with RD patients, and LD anatomy was an independent predictor of in-hospital mortality.

    Full Text Available AbstractObjectives: Regardless of diabetes status, hyperglycemia on arrival for patients presenting with acute coronary syndrome, has been associated with adverse outcomes including death. The aim of this study is to look at the frequency and prognostic significance of acute phase hyperglycemia among patients attending the coronary care unit with acute coronary syndrome over the in-hospital admission days.Methods: The study included 287 consecutive patients in the Al- Faiha Hospital in Basrah (Southern Iraq during a one year period from December 2007 to November 2008. Patients were divided into two groups with respect to admission plasma glucose level regardless of their diabetes status (those with admission plasma glucose of <140 mg/dl (7.8 mmol/L and those equal to or more than that. Acute phase hyperglycemia was defined as a non-fasting glucose level equal to or above 140 mg/dl (7.8 mmol/L regardless of past history of diabetes.Results: Sixty one point seven percent (177 of patients were admitted with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences were found between both groups regarding the mean age, qualification, and smoking status, but males were predominant in both groups. A family history of diabetes, and hypertension, were more frequent in patients with plasma glucose of ≥140 mg/dl (7.8 mmol/L. There were no differences between the two groups regarding past history of ischemic heart disease, stroke, lipid profile, troponin-I levels or type of acute coronary syndrome. Again heart failure was more common in the admission acute phase hyperglycemia group, but there was no difference regarding arrhythmia, stroke, or death. Using logistic regression with heart failure as the dependent variable we found that only the admission acute phase hyperglycemia (OR=2.1344, 95�0CI=1.0282-4.4307; p=0.0419 was independently associated with heart failure. While male gender, family history of diabetes mellitus, hypertension and

    Full Text Available OBJECTIVE: to identify the relationship between different presentations of acute coronary syndrome and cardiovascular risk factors among hospitalized individuals.METHOD: cross-sectional study performed in a teaching hospital in São Paulo, in the State of São Paulo (SP. Socio-demographic, clinical and anthropometric data of 150 individuals hospitalized due to acute coronary syndrome were collected through interviews and review of clinical charts. Association between these data and the presentation of the syndrome were investigated.RESULTS: there was a predominance of ST segment elevation acute myocardial infarction. There was significant association of systemic hypertension with unstable angina and high values of low density lipoprotein with infarction, without influence from socio-demographic characteristics.CONCLUSION: arterial hypertension and high levels of low-density lipoprotein were associated with different presentations of coronary syndrome. The results can provide support for health professionals for secondary prevention programs aimed at behavioural changing.

  15. Frequency of conventional risk factors in patients with acute coronary syndrome in males and females

    Background: The frequency of conventional risk factors for acute coronary syndrome differs in women compared to men, both in the general population and in patients with acute coronary syndrome. Objective: To find out the frequency of conventional risk factors in patients with acute coronary syndrome in males and females that exists in Pakistani patient population. Design: Cross-sectional survey. Material and Methods: A total of one hundred patients with acute coronary syndrome who presented in the Cardiology Department, Mayo Hospital Lahore were interviewed between May, 2008 and March 2009. Patients were enquired about the presence of hypertension and diabetes mellitus. Information was also obtained regarding smoking and history of ischemic heart disease in their first degree relatives. Lipid profile was recorded from the investigation chart of every patient. Results: 91% of subjects had at least one risk factor out of four conventional factors. When comparing men and women, more women were hypertensive and diabetic (p = 0.003 and 0.009 respectively). None of the females had ever smoked as compared to 34% of males (P = <0.001). Conclusion: Women with acute coronary syndrome, when compared to men, have more prevalence of diabetes and hyper-tension, and less prevalence of smoking. Further research is needed to better understand the gender differences in various aspects of ischemic heart disease that exist in our population. (author)

  16. Role of myocardial perfusion imaging in acute coronary syndrome

    Full text: In the cardiac emergency department, a number of patients present with acute chest pain. In case of non diagnostic ECG and enzymes, accurately categorizing the patient in high and low probability is difficult. Aim of study was to evaluate the role of resting myocardial perfusion imaging (MPI) in patients with acute coronary syndrome (ACS) and then to compare the results with subsequent stress imaging. Material and Methods. A total of 34 patients were selected for the study, which were divided into three groups on the basis of respective probabilities of having ACS. This probability was decided on the basis of nature of chest pain, ECG findings, enzymes levels, and age and sex. Arbitrary score was given to patient's condition. This score ranged from 1 to 14. Patients with score between 1-6 were assigned low probability, from 7-10 were assigned intermediate probability and patients having score greater than 11 were placed in high probability groups. Patients in the low and intermediate probability groups were injected with Tc99m- MIBI within 6 hours of onset of chest pain and were undergone resting myocardial perfusion imaging (MPI) 3 to five hours after injection.. Imaging in high probability group was performed at discharge. Four weeks after the acute event all the patients underwent stress myocardial perfusion imaging. Results: All patients (100%) with low probability of ACS (n=10) showed negative resting scans. On stress MPI two patients (20%) showed new defects. Patient with high probability of ACS (n=12), all were positive 100% on resting MPI. On stress MPI, three showed (25%) no change from rest MPI, while nine patients (75%) showed augmentation of defects and four out of these nine patients (33%) also showed new perfusion defects. Patients with intermediate probability of ACS (n=12), three showed positive rest MPI (25%). On stress MPI out of these three cases, one showed (8%) no change from rest MPI and two showed (17%) augmentation of defect shown

    It is challenging to undo early percutaneous intervention (PCI) in the elderly with acute coronary syndrome (ACS). Fifteen patients older than 65 years with ACS within 24 hours of the event were admitted from April 4, 2004 to December 12, 2005. All the patients had early percutaneous coronary intervention and were followed up for 6-12 months by telephone or in the out-patient department. Nine of the 15 patients exhibited acute myocardial infarction (AMI). Six exhib-ited unstable angina (UA). All the patients had early PCI. The average door-to-balloon time was 78 minutes (40-110 minutes). The average PCI time was 99 minutes (68-120 minutes). Nineteen of 36 lesions in the fifteen angioplasty patients were treated and 20 stents were implanted in total. All the procedures were considered successful. Neither deaths nor recurrent angina occurred in the 6-12 months of follow-up. It was shown that early PCI might be an effective and safe method to treat eld-erly patients with ACS.

    2016-04-01

    The effect of obstructive sleep apnea (OSA) on clinical outcomes after acute coronary syndrome (ACS) is incompletely defined. We sought to determine the prevalence of OSA in patients with ACS and evaluate prognostic impact of OSA and continuous positive airway pressure (CPAP) therapy in these patients. This was a prospective longitudinal cohort study of 73 patients admitted on cardiac intensive care unit for ACS. Cardiorespiratory sleep study and/or polysomnography were performed in all patients. CPAP was recommended if Apnea-Hypopnea Index ≥5. The main study outcome was a composite of death for any cause, myocardial infarction, and myocardial revascularization. OSA was diagnosed in 46 patients (63%). Age and cardiovascular risk factors were not significantly different between groups. OSA was classified as mild (m-OSA) in 14 patients (30%) and as moderate-to-severe (s-OSA) in 32 patients (70%). After a median follow-up of 75 months (interquartile range 71 to 79), patients with s-OSA had lower event-free survival rate. After adjustment for gender, patients with s-OSA showed a significantly higher incidence of the composite end point (hazard ratio 3.58, 95% CI 1.09 to 17.73, p = 0.035). Adherence to CPAP occurred in 19 patients (41%), but compliance to CPAP therapy did not reduce the risk of composite end point (hazard ratio 0.87, 95% CI 0.31 to 2.46, p = 0.798). In conclusion, OSA is an underdiagnosed disease with high prevalence in patients with ACS. It is urgent to establish screening protocols because those have high diagnostic yield and allow identifying a group of patients with manifestly unfavorable prognosis. PMID:26857162

    Full Text Available OBJECTIVES: Atherosclerosis is a chronic inflammatory disease. Research has focused on identifying specific serum biomarkers to detect vulnerable plaques. These markers serve as diagnostic tools for acute coronary syndrome and assist in identifying high-risk patients. However, the existing data are limited and conflicting. This study tested the hypothesis that CD137 levels identify patients with acute coronary syndrome who are at a heightened risk for recurrent cardiac events. METHODS: The levels of soluble CD137 (sCD137 were measured using ELISA in 180 patients with acute coronary syndrome and 120 patients with acute chest pain. Platelet activation was assessed by flow cytometry. Receiver operating characteristic curve analysis was performed to evaluate the prognostic characteristics of sCD137. RESULTS: The levels of sCD137 were elevated in 75 patients with acute coronary syndromes and 20 patients with acute chest pain (>35.0 ng/ml. In patients with acute coronary syndrome, elevated sCD137 levels (>35.0 ng/ml indicated an increased risk for major adverse cardiovascular events (OR =1.93, 95% CI: 1.39-2.54. Elevated serum levels of sCD137 and cTnT were correlated with a significantly increased risk of major adverse cardiovascular events in both groups after 30 days, six months and nine months of follow-up. The increased sCD137 levels were significantly correlated with the levels of troponin I (r = 0.4799, p<0.001. Importantly, 26 patients with normal cTnI levels had acute coronary syndrome. However, elevated sCD137 levels identified these patients as a being high-risk subgroup (OR = 2.14, 95% CI: 1.25-4.13. CONCLUSIONS: Elevated sCD137 levels indicate an increased risk of cardiovascular events in patients with acute coronary syndrome. Soluble CD137 may be a useful prognostic marker or indicator for adverse events in patients with acute coronary syndrome.

  1. Multislice CT characteristics of coronary atherosclerotic plaques in acute coronary syndrome

    Objective: To compare the plaque characteristics of acute coronary, syndrome (ACS) and stable angina (SA) by multislice CT(MSCT). Methods: MSCT images of 27 patients with ACS and SA were compared. Results: The frequency of positive vascular remodeling was significantly different in ACS (19/31) and SA (6/41, χ2=16.95, P2=8.00, P2=3.62, P<0.05). The mean CT value of non- calcified plaques in ACS [(35.0±15.1) HU] was lower than in SA [(67.5±26.5) HU(t=4.82,P< 0.01)].

    Pheochromocytoma is a tumor arising from neuroectodermal chromaffin tissues in the adrenal gland or extra-adrenal paraganglia (paragangliomas). The prevalence of the tumor is 0.1%-0.6% in the hypertensive population, of which 10%-20% are malignant. Pheochromocytoma produces, stores, and secretes catecholamines, as well as leads to hypertensive crisis, arrhythmia, angina, and acute myocardial infarction without coronary artery diseases. We report a case of acute coronary syndrome (ACS) with a ...

    2012-07-01

    Full Text Available Abstract Background While prior research has provided important information about readmission rates following percutaneous coronary intervention, reports regarding charges and length of stay for readmission beyond 30 days post-discharge for patients in a large cohort are limited. The objective of this study was to characterize the rehospitalization of patients with acute coronary syndrome receiving percutaneous coronary intervention in a U.S. health benefit plan. Methods This study retrospectively analyzed administrative claims data from a large US managed care plan at index hospitalization, 30-days, and 31-days to 15-months rehospitalization. A valid Diagnosis Related Group code (version 24 associated with a PCI claim (codes 00.66, 36.0X, 929.73, 929.75, 929.78–929.82, 929.84, 929.95/6, and G0290/1 was required to be included in the study. Patients were also required to have an ACS diagnosis on the day of admission or within 30 days prior to the index PCI. ACS diagnoses were classified by the International Statistical Classification of Disease 9 (ICD-9-CM codes 410.xx or 411.11. Patients with a history of transient ischemic attack or stroke were excluded from the study because of the focus only on ACS-PCI patients. A clopidogrel prescription claim was required within 60 days after hospitalization. Results Of the 6,687 ACS-PCI patients included in the study, 5,174 (77.4% were male, 5,587 (83.6% were Conclusions For ACS patients who underwent PCI, revascularization procedures represented a large portion of rehospitalizations. Revascularization procedures appear to be the most frequent, most costly, and earliest cause for rehospitalization after ACS-PCI.

  6. Prevalence of Burnout Syndrome in Patients Admitted with Acute Coronary Syndrome

    Ana Cláudia Giaxa Prosdócimo

    2015-03-01

    Full Text Available Background: Burnout Syndrome is the extreme emotional response to chronic occupational stress, manifesting as physical and mental exhaustion. Although associated with higher prevalence of cardiovascular risk factors, no study so far has evaluated whether the Burnout Syndrome could be a prevalent factor in non-elderly individuals active in the labor market, admitted for acute coronary syndrome (ACS. Objective: To evaluate the prevalence of the Burnout Syndrome in non-elderly, economically active patients, hospitalized with ACS. Methods: Cross-sectional study conducted in a tertiary and private cardiology center, with economically active patients aged <65 years, hospitalized with diagnosis of ACS. The Burnout Syndrome was evaluated with the Burnout Syndrome Inventory (BSI, which assesses workplace conditions and four dimensions that characterize the syndrome: emotional exhaustion (EE, emotional distancing (EmD, dehumanization (De and professional fulfillment (PF. The Lipp’s Stress Symptoms Inventory for Adults (LSSI was applied to evaluate global stress. Results: Of 830 patients evaluated with suspected ACS, 170 met the study criteria, 90% of which were men, overall average age was 52 years, and 40.5% had an average income above 11 minimum wages. The prevalence of the Burnout Syndrome was 4.1%. When we evaluated each dimension individually, we found high EE in 34.7%, high De in 52.4%, high EDi in 30.6%, and low PF in 5.9%. The overall prevalence of stress was 87.5%. Conclusion: We found a low prevalence of Burnout Syndrome in an economically active, non-elderly population among patients admitted for ACS in a tertiary and private hospital.

    2005-01-01

    Objective: To determine to what extent evidence based guidelines are followed in the management of acute coronary syndromes (ACS) in the UK, elsewhere in Europe, and multinationally, and what the outcomes are. Design: Multinational, prospective, observational registry (GRACE, global registry of acute coronary events) with six months’ follow up. Setting: Patients presenting to a cluster of hospitals. The study was designed to collect data representative of the full spectrum of ACS in specific geographic populations. Patients: Patients admitted with a working diagnosis of unstable angina or suspected myocardial infarction (MI). Main outcome measures: Death during hospitalisation and at six months’ follow up (adjusted for baseline risks). Results: In ST elevation MI, reperfusion was applied more often in the UK (71%) than in Europe (65%) and multinationally (59%) (p < 0.01). However, this was almost entirely by lytic treatment, in contrast with elsewhere (primary percutaneous coronary intervention 1%, 29%, 16%, respectively). Statins were applied more frequently in the UK for all classes of patients with ACS (p < 0.0001). In contrast there was lower use of revascularisation procedures in non-ST MI (20% v 37% v 28%, respectively) and glycoprotein IIb/IIIa antagonists (6% v 25% v 26%, respectively). In-hospital death rates, adjusted for baseline risk, were not significantly different but six month death rates were higher in the UK for ST elevation MI (7.2% UK, 4.3% Europe, 5.3% multinationally; p < 0.0001) and non-ST elevation MI (7.5%, 6.2%, and 6.7%, respectively; p  =  0.012, UK v Europe). Conclusions: Current management of ACS in the UK more closely follows the recommendations of the National Service Framework than British or European guidelines. Differences in practice may account for the observed higher event rates in the UK after hospital discharge. PMID:15710703

    Greater antithrombotic potency new antiplatelet agents have been added such as prasugrel (PR) and ticagrelor to the traditional use of clopidogrel (CL) in the treatment of acute coronary syndrome (ACS). This study was aimed at comparing the incidence of long term ischemic and hemorrhagic events in patients treated with CL or PR during hospitalization. Retrospective ACS data base analysis performed by our cardiology service was completed prospectively. There were consecutively included all patients with percutaneous coronary intervention (PCI) during hospitalization due to ACS from December 2011 thru December 2012. A total of 398 ACS patients who underwent PCI with stent implantation were recruited. No differences in cardiovascular related deaths were observed in both groups (PR 2.9% vs. CL 2.5%, p=0.48). PR group showed less re-infraction (1.9% vs. 6.8%, p=0.01) with more total bleedings (18.5% vs. 8.5%, p=0.001) and minor bleedings (12.4% vs. 3.4%, p<0.001) with no differences in major and life threatening bleedings (p=ns). Multivariate analysis showed that independent predictors of cardiovascular mortality were age (OR 1.08, CI 95% 1.02-1.16) and renal failure (OR 6.98, CI 95% 1.23-39.71). Independent predictors for total bleeding were age (OR 1.06, CI 95% 1.02-1.09),ST segment elevation myocardial infarction (OR 1.99, CI 95% 1.05-3.79), renal failure (OR 3.32, CI 95% 1.62-6.78) and prasugrel use (OR 3.97, CI 95% 1.87-8.41). Use of prasugrel, in the ACS that requires PCI with stent, is associated with a lower myocardial infarction a year after follow-up, and it also leads to an increase of milder hemorrhage. No significant differences were observed in the cardiovascular mortality of both groups. PMID:26339874

    2016-04-01

    Acute coronary syndrome includes unstable angina and myocardial infarction with or without ST-segment elevation, is life-threatening disorders that remain a source of high morbidity and mortality despite advances in treatment. The aim of the study was to evaluate the prognostic role of serum cTnI, CK-MB, hsCRP, MPO and BNP in newly diagnosed acute coronary syndrome patients. This cohort study was carried out in the Department of Biochemistry, Bangabandhu Sheikh Mujib Medical University in cooperation with the Department of Cardiology, BSMMU and NICVD during the period of March 2013 to February 2014. A total 100 newly diagnosed acute coronary syndrome patients were purposively enrolled in this study within 24 hours of attacked, among them 30 were NSTEMI, 65 were STEMI and 5 were unstable angina. Serum cTnI, CK-MB, hsCRP, MPO and BNP concentrations were measured at enrollment and grouping of the study subjects were done on the basis of their empirical cut off values into two groups. In cTnI: Group I (n=20) having cTnI ratio analysis showed significantly worse outcome in Group II acute coronary syndrome patients in comparison to Group I. In case of cTnI RR - 1.85 at 95% CI 1.19-2.88, in case of CK-MB RR- 1.88 at 95% CI 1.21-2.92, in case of hsCRP RR- 2.05 at 95% CI 1.30-3.25, in case of MPO RR- 2.59, at 95% CI 1.49-4.49, and in case of BNP RR- 3.47 at 95% CI 2.5-5.36. It was concluded from this study that base line serum cTnI, CK-MB, hsCRP, MPO, and BNP can be used clinically as prognostic biomarkers of acute coronary syndrome. PMID:27277367

  14. Emerging antiplatelet therapy for coronary artery disease and acute coronary syndrome.

    Packard, Kathleen A; Campbell, Jennifer A; Knezevich, Jon T; Davis, Estella M

    2012-03-01

    Antiplatelet therapy is used widely with proven benefit for the prevention of further ischemic cardiac complications in patients with known coronary artery disease (CAD) and a history of acute coronary syndrome (ACS). The limitations of conventional antiplatelet therapy with aspirin, clopidogrel, or prasugrel, as well as the fact that rates of recurrent ischemic events still remain high with use of these agents, underscore the need to investigate alternate agents that may further reduce event rates while limiting bleeding risk. The selection of antiplatelet therapy is further influenced by the following: ticagrelor was approved in July 2011 by the United States Food and Drug Administration (FDA), and clopidogrel is slated to become available as a generic productin 2012. We provide an overview of emerging agents for the treatment of CAD and ACS, including the reversible P2Y(12) antagonists ticagrelor, cangrelor, and elinogrel, and a new class of oral protease-activated receptor-1 (PAR-1) inhibitors, vorapaxar and atopaxar.The recently approved P2Y(12) antagonists prasugrel and ticagrelor demonstrate enhanced ability to prevent adverse cardiac outcomes. However, this comes at a cost of a potential increased risk of bleeding. New adverse effects have also emerged, including dyspnea for all of the reversible P2Y(12) antagonists (ticagrelor, cangrelor, and elinogrel) and ventricular pauses for ticagrelor. In addition, the newer P2Y(12) antagonists have a faster onset and offset. Two of these agents, cangrelor and elinogrel, are available as intravenous formulations, which may provide additional benefits in patients who undergo coronary artery bypass graft (CABG) surgery. Trials with the PAR-1 inhibitors have also shown trends toward reductions in cardiac events, but not without the possibility of increased bleeding. More than ever, as the arsenal of antiplatelet therapy expands, health care providers need to understand the pharmacologic and pharmacodynamic differences

    2009-01-01

    Abstract Although an association between elevated white blood cells (WBC) count and mortality in patients with acute coronary syndromes (ACS) has been established, the independence of this association from coronary risk factors and C-reactive protein has been inadequately studied. This prospective registry included 4329 patients with ACS treated with percutaneous coronary intervention (PCI): 1059 patients with ST-segment elevation acute myocardial infarction, 1753 patients with non...

    Pheochromocytoma is a tumor arising from neuroectodermal chromaffin tissues in the adrenal gland or extra-adrenal paraganglia (paragangliomas). The prevalence of the tumor is 0.1%-0.6% in the hypertensive population, of which 10%-20% are malignant. Pheochromocytoma produces, stores, and secretes catecholamines, as well as leads to hypertensive crisis, arrhythmia, angina, and acute myocardial infarction without coronary artery diseases. We report a case of acute coronary syndrome (ACS) with a final diagnosis of multiple endocrine neoplasia with pheochromocytoma and medullary thyroid carcinoma (MTC). PMID:26487970

  20. Revascularization Strategies in Patients with Diabetes Mellitus and Acute Coronary Syndrome.

    Buntaine, Adam J; Shah, Binita; Lorin, Jeffrey D; Sedlis, Steven P

    2016-08-01

    Patients with diabetes mellitus (DM) have more severe CAD and higher mortality in acute coronary syndrome (ACS) than patients without DM. The optimal mode of revascularization-coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI)-remains controversial in this setting. For patients with DM and ST-segment elevation myocardial infarction, prompt revascularization of the culprit artery via PCI is generally preferable. In non-ST-elevation ACS, the decision on mode of revascularization is more challenging. Trials comparing CABG with percutaneous transluminal coronary angioplasty, bare metal stents, and first-generation drug-eluting stents in DM patients with multivessel have demonstrated decreased mortality in those receiving CABG. On the other hand, trials and retrospective analyses comparing CABG to PCI with second-generation drug-eluting stents have not shown a statistically significant mortality benefit favoring CABG. This potentially narrowed that gap between CABG and PCI requires further investigation. PMID:27339854

  1. Relationship between serum TNF-α, IL-8 levels and acute coronary syndrome in aged patients

    Objective: To study the relationship between serum levels of TNF-α, IL-8 and the severity of coronary heart disease in aged patients and to assess the usefulness of these two cytokines as markers of atheromatous plaque stability. Methods: Serum TNF-α, IL-8 levels were determined with RIA in 85 aged patients with coronary heart disease, in which 42 were of the acute coronary syndrome type (ACS) and 43 were of the stable coronary heart disease type (SCHD) as well as in 30 controls. Results: Serum levels of TNF-α, IL-8 in both the patients with ACS and SCHD were significantly higher than those in controls ( P 0.05). Conclusion: The cytokines TNF-α and IL-8 were regarded as important markers for stability of the atheromatous plaque. However, data from this article did not give much support to that hypothesis (no significant difference data). (authors)

    2015-01-01

    Full Text Available Introduction. Risk stratification is nowadays crucial when estimating the patient’s prognosis in terms of treatment outcome and it also helps in clinical decision making. Several risk assessment models have been developed to predict short-term outcomes in patients with acute coronary syndrome. This study was aimed at developing an outcome prediction model for patients with acute coronary syndrome submitted to percutaneus coronary intervention using data mining approach. Material and Methods. A total of 2030 patients hospitalized for acute coronary syndrome and treated with percutaneous coronary intervention from December 2008 to December 2011 were assigned to a derivation cohort. Demographic and anamnestic data, clinical characteristics on admission, biochemical analysis of blood parameters on admission, and left ventricular ejection fraction formed the basis of the study. A number of machine learning algorithms available within Waikato Environment for Knowledge Discovery had been evaluated and the most successful was chosen. The predictive model was subsequently validated in a different population of 931 patients (validation cohort, hospitalized during 2012. Results. The best prediction results were achieved using Alternating Decision Tree classifier, which was able to predict in-hospital mortality with 89% accuracy, and preserved good performance on validation cohort with 87% accuracy. Alternating Decision Tree classifier identified a subset of 6 attributes most relevant to mortality prediction: systolic and diastolic blood pressure, heart rate, left ventricular ejection fraction, age, and troponin value. Conclusion. Data mining approach enabled the authors to develop a model capable of predicting the in-hospital outcome following percutaneous coronary intervention. The model showed excellent sensitivity and specificity during internal validation.

  3. Evaluation of coronary artery remodeling in patients with acute coronary syndrome and stable angina by multislice computed tomography

    Multislice computed tomography (MSCT) was used to evaluate coronary artery remodeling in patients with acute coronary syndrome (ACS) and stable angina (SA). MSCT was performed in 31 patients with ACS and 26 patients with SA and intravascular ultrasound (IVUS) was performed in 28 of these 57 patients. In both the MSCT and IVUS analyses, coronary artery remodeling was assessed by the remodeling index (RI): RI>1.10 was defined as positive coronary artery remodeling (PCAR) and RI<0.95 was defined as negative coronary artery remodeling (NCAR). The RI assessed by MSCT closely correlated with that of IVUS (r=0.86, n=28). The vessel area at the region of maximum luminal narrowing was also comparable between the MSCT and IVUS measurements (r=0.92). PCAR was present in 19 patients (61.3%) with ACS, but in none of the patients with SA (p<0.0001). However, NCAR was present in only 1 patient with ACS (3.2%), but was present in 18 patients (62.9%) with SA. The RI was significantly larger in patients with ACS (1.19±0.18) than in those with SA (0.89±0.10, p<0.0001). MSCT accurately assesses coronary artery remodeling. (author)

  4. The Role of Infection in the Development of Acute Coronary Syndrome

    Full Text Available AIM: A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, and Cytomegalovirus can initiate or maintain the atherosclerotic process. Aim of this study is to evaluate the probable relationship between serum titers of some various infectious agents and the development of acute coronary syndrome and to investigate the relationship between these infectious agents and other risk factors of acute coronary syndrome (smoking, hypertension, dyslipidemia, diabetes, and family history of CVD. METHOD: This is a hospital based case- control study was conducted on two groups: patients group included 86 patients, cases were collected from patients admitted to Cardiac Care Unit (CCU of Cleopatra hospital, and Ain Shams University hospital with acute myocardial infarction between January 2010 and June 2010 and control group included 86 apparently healthy individuals. A questionnaire was designed to determine conventional coronary artery risk factors. The sero-prevalence of Chlamydia pneumoniae (C. pneumoniae, Cytomegalovirus and Helicobacter pylori (H. pylori IgG antibodies were evaluated using quantitative enzyme-linked immunosorbent assay (ELISA. RESULTS: The results showed that there was an increased level of serum IgG antibodies of C. pneumoniae, Cytomegalovirus and Helicobacter pylori among patients with acute coronary syndrome compared to control subjects CONCLUSION: C. pneumoniae, Cytomegalovirus and Helicobacter pylori were expected to be predictors for the development of coronary artery disease, as there was significant elevation of the serum level of IgG antibodies against them.

    AIM: Escitalopram may prevent depression following acute coronary syndrome. We sought to estimate the effects of escitalopram on self-reported health and to identify subgroups with higher efficacy. METHODS: This is a secondary analysis of a 12-month double-blind clinical trial randomizing non......-depressed acute coronary syndrome patients to escitalopram (n = 120) or matching placebo (n = 120). The main outcomes were mean scores on Short Form 36 Health Survey (SF-36) domains, and diagnosis of depression was adjusted for baseline SF-36 scores. RESULTS: Escitalopram did not yield different SF-36...... trajectories on any scale compared with placebo (P > 0.28). Efficacy of escitalopram may have been better among those scoring at least the normative score on general health perceptions (hazard ratio (HR) for depression 0.17 (95% confidence interval 0.02-1.42) ) or social functioning (HR = 0.12 (0...

  7. High-Risk Acute Coronary Syndrome in a Patient with Coronary Subclavian Steal Syndrome Secondary to Critical Subclavian Artery Stenosis

    Zaher Fanari

    2014-01-01

    Full Text Available Patients with multivessel coronary artery disease are more likely to have extensive atherosclerosis that involves other major arteries. Critical subclavian artery (SCA stenosis can result in coronary subclavian steal syndrome that may present as recurrent ischemia and even myocardial infarction in patients with coronary artery bypass graft (CABG. In patients with concomitant severe native coronary disease, occluded saphenous venous grafts (SVG to other arteries, percutaneous intervention on critical subclavian artery (SCA stenosis that will compromise the blood flow to left internal mammary graft (LIMA and left anterior descending (LAD artery will be a high-risk procedure and may be associated with cardiogenic shock, especially in patients with preexisting ischemic cardiomyopathy. The use of percutaneous left ventricular (LV assist device like Impella will offer better hemodynamic support and coronary perfusion and therefore results in decreased myocardial damage, maximized residual cardiac function, and lower incidence of cardiogenic shock.

    Greater ex vivo platelet aggregation to agonists may identify individuals at risk of acute coronary syndromes (ACS). However, increased aggregation to a specific agonist may be masked by inherent variability in other activation pathways. In this study, we inhibited the cyclooxygenase-1 (COX1) pathway with 2-week aspirin therapy and measured residual aggregation to collagen and ADP to determine whether increased aggregation in a non-COX1 pathway is associated with incident ACS. We assessed ex ...

    2012-04-01

    Atherosclerotic cardiovascular disease is an epidemic in today's world. It is one of the most common causes of hospitalization and death. Therefore, remedies to control or heal the disease are continuously sought. In addition to scientifically researched therapies, patients frequently utilize alternative medicine. However, effective and toxic doses, metabolisms, and drug interactions of the herbs and herbal nutrition supplements are largely unknown. Herein, we present two cases with acute coronary syndrome. The first case was admitted with a diagnosis of acute inferior myocardial infaction (MI) and a stent was implanted to the occluded right coronary artery (RCA). There was a 50% stenosis in his left anterior descending artery (LAD). He was admitted with a diagnosis of non-ST elevation MI (NSTEMI) 6 months later. In the coronary angiogram, there was stent restenosis in RCA, the lesion in LAD had become thrombotic and progressed to a stenosis of 90%. He was referred to surgical revascularization. The second case was admitted for acute inferior MI and a stent was implanted to the occluded circumflex artery. Two months later, he was hospitalized for NSTEMI. Progression of coronary plaques to stenosis and stent restenosis was detected and he was referred to surgical revascularization. Both patients used the product sold as Clavis Panax, which contains panax ginseng, tribulus terrestris, and oat, after their first coronary intervention. Intake of a mixture of plant extracts may have serious consequences in humans as drug interactions and side effects are unknown. PMID:22864326

  19. Soluble Receptor for Advanced Glycation End Product: A Biomarker for Acute Coronary Syndrome

    Louise J. N. Jensen

    2015-01-01

    Full Text Available The receptor of advanced glycation end products (RAGE and its ligands are linked to the pathogenesis of coronary artery disease (CAD, and circulating soluble receptor of advanced glycation end products (sRAGE, reflecting the RAGE activity, is suggested as a potential biomarker. Elevated sRAGE levels are reported in relation to acute ischemia and this review focuses on the role of sRAGE as a biomarker for the acute coronary syndrome (ACS. The current studies demonstrated that sRAGE levels are elevated in relation to ACS, however during a very narrow time period, indicating that the time of sampling needs attention. Interestingly, activation of RAGE may influence the pathogenesis and reflection in sRAGE levels in acute and stable CAD differently.

    Background Many patients with acute coronary syndrome (ACS) develop recurrent angina (RA) during hospitalization. The aim of this non-randomized, prospective study was to investigate the predictive factors of RA in unselected patients with ACS enrolled in the global registry acute coronary events (GRACE) during hospitalization in China. Methods Between March 2001 and October 2004, enrolled were 1433 patients with ACS, including ST segment elevation myocardial infarction (662, 46.2%), non-ST segment elevation myocardial infarction (239, 16.7%) and unstable angina (532, 37.1%). The demographic distribution, medical history and clinical data were collected to investigate the predictive factors of RA by Logistic regression.Results During hospitalization 275 (19.2%) patients were documented with RA including unstable angina (53.2%), non-ST segment elevation myocardial infarction (27.5%), ST segment elevation myocardial infarction (19.3%). A comorbidity of dyslipidemia, prior angina, percutaneous coronary Intervention (PCI) within 6 months was more common in patients with RA, P<0.05. In the patients with RA, a significantly higher proportion of patients with acute pulmonary edema was observed, 23 (8.4%) versus 43 (3.7%), P=0.001. Acute renal failure was present in 8 (2.9%) of patients with RA versus 19 (1.6%) of patients without RA,P=0.165. Hemorrhagic events were present in 6 (2.2%) of patients with RA versus 8 (0.7%) of patients without RA, ventricular tachycardia/ ventricular fibrillation events in 12 patients (4.3%) versus 22 patients (1.9%), congestive heart failure in 69 patients (25.0%) versus 94 patients (8.1%), myocardial re-infarction in 28 patients (10.1%) versus 15 patients (1.3%), P<0.05, respectively. A lower proportion of patients with RA underwent in-hospital PCI, 687 (59.3%) versus 114 (41.5%), P=0.000. A higher proportion of patients with RA received heparin, 260 (94.5%) versus 1035 (89.4%), P=0.006; and beta-blockers 176(64.0%) versus 864 (74

    2015-01-01

    ABSTRACT OBJECTIVE : To analyze if the demographic and socioeconomic variables, as well as percutaneous coronary intervention are associated with the use of medicines for secondary prevention of acute coronary syndrome. METHODS : In this cohort study, we included 138 patients with acute coronary syndrome, aged 30 years or more and of both sexes. The data were collected at the time of hospital discharge, and after six and twelve months. The outcome of the study was the simultaneous use of medicines recommended for secondary prevention of acute coronary syndrome: platelet antiaggregant, beta-blockers, statins and angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker. The independent variables were: sex, age, education in years of attending, monthly income in tertiles and percutaneous coronary intervention. We described the prevalence of use of each group of medicines with their 95% confidence intervals, as well as the simultaneous use of the four medicines, in all analyzed periods. In the crude analysis, we verified the outcome with the independent variables for each period through the Chi-square test. The adjusted analysis was carried out using Poisson Regression. RESULTS : More than a third of patients (36.2%; 95%CI 28.2;44.3) had the four medicines prescribed at the same time, at the moment of discharge. We did not observe any differences in the prevalence of use in comparison with the two follow-up periods. The most prescribed class of medicines during discharge was platelet antiaggregant (91.3%). In the crude analysis, the demographic and socioeconomic variables were not associated to the outcome in any of the three periods. CONCLUSIONS : The prevalence of simultaneous use of medicines at discharge and in the follow-ups pointed to the under-utilization of this therapy in clinical practice. Intervention strategies are needed to improve the quality of care given to patients that extend beyond the hospital discharge, a critical point of transition

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%, dyslipidemia (47.5%, and diabetes (37.7%. In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that

    Background Despite outstanding antiplatelet properties of aspirin and clopidogrel,some patients taking these drugs continue to suffer complications.Antiplatelet resistance appears to be a new prognostic factor in acute coronary syndrome patients for clinical events associated with stent thrombosis (ST).However,there is no optimal method to identify it and assess its correlation to clinical outcomes.This study sought to evaluate the predictive value of antiplatelet resistance assessed by whole blood impedance aggregometry for the risk of early ST in patients with acute coronary syndrome who underwent coronary stenting.Methods Platelet responses to aspirin and clopidogrel in 86 patients with acute coronary syndrome were measured by whole blood impedance aggregometry.Spontaneous platelet aggregation was defined as antiplatelet resistance identified by the increased electrical impedance.The clinical endpoint was early stent thrombosis during 30-day follow-up after coronary stenting.Results The prevalence of aspirin resistance,clopidogrel resistance and dual resistance of combined clopidogrel and aspirin resistance were 19.8%,12.8% and 5.8% respectively.Diabetes,female and higher platelet counts were more frequently detected in clopidogrel-resistant and dual-resistant patients.During 30-day follow-up,the patients with clopidogrel resistance and dual resistance had higher incidence of early stent thrombosis (18.2% vs.1.3%,40.0% vs.1.2%,P <0.05).Binary Logistic Regression analysis indicated that dual resistance remained an independent predicator for early stent thrombosis (odds ratio 34.064,95% CI 1.919-604.656,P=-0.016).Conclusions Antiplatelet resistance assessed by whole blood impedance aggregometry is paralleled to clinical events,and dual antiplatelet resistance is an independent predicator for early stent thrombosis in patients with acute coronary syndrome.As a physiological assessment of platelet reactivity,whole blood impedance aggregometry is a

    Introduction In the last decade a range of recommendations to increase awareness of depression in acute coronary syndrome patients have been published. To test the impact of those recommendations we examine and compare recent time trends in depression among acute coronary syndrome patients and a reference population. Methods 87 218 patients registered with acute coronary syndrome from 2001-2009 in Denmark and a match reference population were followed through hospital registries and medication prescriptions for early (≤30 days), intermediate (31 days to 6 months) and later (6 months to 2 years) depression in the acute coronary syndrome population and overall depression in the reference population. Cox regression models were used to compare hazard ratios (HRs) for depression over calendar years. Results During the study period, 11.0% and 6.2% were diagnosed with depression in the acute coronary syndrome population and in the reference population, respectively. For the acute coronary syndrome population, the adjusted HRs increased for early (HR (95% CI) 1.04 (1.01-1.06)) and intermediate depression (HR (95% CI) 1.01 (1.00-1.03)), whereas the adjusted HRs did not change for later depression (HR (95% CI) 0.99 (0.98-1.00)). For the reference population the adjusted HRs for depression increased through the study period (HR (95% CI) 1.01 (1.01-1.03)). Conclusion Increase in diagnoses of depressions within 6 months of acute coronary syndrome may be explained by increased focus on depression in this patient group in combination with increased awareness of depression in the general population.

    The aim of the present study was to evaluate the plaque components and the predictors of thin-cap fibroatheroma (TCFA) in anemic patients with acute coronary syndrome using virtual histology-intravascular ultrasound (VH-IVUS). Anemia was defined according to criteria of the World Health Organization, (i.e. , hemoglobin levels < 13 g/dL in men and < 12 g/dL in women) and we compared VH-IVUS findings between anemia group (171 patients, 260 lesions) and non-anemia group (569 patients, 881 lesion...

  8. Efficacy of multislice computed tomography for the detection of acute coronary syndrome in the emergency department

    The diagnosis of acute coronary syndrome (ACS), especially non-ST-elevation myocardial infarction and unstable angina in the emergency department (ED) still remains a challenge. Multislice computed tomography (MSCT) allows assessment of not only coronary artery stenoses and occlusions, but also assessment of coronary artery plaques and myocardial perfusion status. MSCT was performed in 31 patients who were admitted to the ED because of chest pain persisting at least 30 min and non-diagnostic electrocardiogram (ECG) changes and normal serum enzyme concentrations. Using MSCT, ACS was defined by coronary artery stenosis ≥75% accompanied by computed tomography (CT)-low-density plaques, and/or by the presence of myocardial perfusion defects. ACS was confirmed by coronary stenosis ≥75% by coronary angiography and/or subsequent elevation of troponin I concentration. In total, 22 patients were diagnosed as having ACS. MSCT detected stenoses with CT-low-density plaques in 21 and non-transmural myocardial perfusion defect in 3 patients. There was 1 false-positive and 1 false-negative result. The sensitivity and specificity of MSCT to identify ACS was 95.5% and 88.9%, respectively. MSCT provides diagnostic operating characteristics suitable for triage of patients with ACS in the ED.

People who were not-married and depressed at the time of an acute cardiac episode were at higher risk of fatal events than people who were married, irrespective of depression status and other characteristics.Keywords: marital status, acute coronary syndromes, risk

  10. A patient with non-ST-segment elevation acute coronary syndrome: Is it possible to predict the culprit coronary artery?

    Lindow, Thomas; Pahlm, Olle; Nikus, Kjell

    2016-01-01

    In acute coronary syndromes without ST-segment elevation (NSTE-ACS), identification of the culprit artery is, most often, not possible. In this case report, we elaborate on the likelihood of different culprit arteries in a patient with NSTE-ACS. While her symptoms were progressing, typical ECG findings of ischemia in the left coronary territories were diminishing. Instead, dynamic T-wave changes in the inferior leads were present and were most likely postischemic and "reischemic." Although the culprit artery could not be identified with certainty by means of these subtle changes, they correlated well with the findings on angiography and the ECG recorded afterward. This case report demonstrates the importance of analyzing ECG and its temporal changes in conjunction with evolving symptoms. PMID:27212142

    Background Several risk scores were developed for acute coronary syndrome (ACS) patients, but their use is limited by their complexity. Purpose The purpose of this study was to identify predictors at admission for in-hospital mortality in ACS patients in western Romania, using a simple risk-assessment tool – the new Canada acute coronary syndrome (C-ACS) risk score. Patients and methods The baseline risk of patients admitted with ACS was retrospectively assessed using the C-ACS risk score. The score ranged from 0 to 4; 1 point was assigned for the presence of each of the following parameters: age ≥75 years, Killip class >1, systolic blood pressure 100 bpm. Results A total of 960 patients with ACS were included, 409 (43%) with ST-segment elevation myocardial infarction (STEMI) and 551 (57%) with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). The C-ACS score predicted in-hospital mortality in all ACS patients with a C-statistic of 0.95 (95% CI: 0.93–0.96), in STEMI patients with a C-statistic of 0.92 (95% confidence interval [CI]: 0.89–0.94), and in NSTE-ACS patients with a C-statistic of 0.97 (95% CI: 0.95–0.98). Of the 960 patients, 218 (22.7%) were aged ≥75 years. The proportion of patients aged ≥75 years was 21.7% in the STEMI subgroup and 23.4% in the NSTE-ACS subgroup (P>0.05). Age ≥75 years was significantly associated with in-hospital mortality in ACS patients (odds ratio [OR]: 3.25, 95% CI: 1.24–8.25) and in the STEMI subgroup (OR >3.99, 95% CI: 1.28–12.44). Female sex was strongly associated with mortality in the NSTE-ACS subgroup (OR: 27.72, 95% CI: 1.83–39.99). Conclusion We conclude that C-ACS score was the strongest predictor of in-hospital mortality in all ACS patients while age ≥75 years predicted the mortality well in the STEMI subgroup.

  12. Nonantithrombotic medical options in acute coronary syndromes: old agents and new lines on the horizon.

    Soukoulis, Victor; Boden, William E; Smith, Sidney C; O'Gara, Patrick T

    2014-06-01

    Acute coronary syndromes (ACS) constitute a spectrum of clinical presentations ranging from unstable angina and non-ST-segment elevation myocardial infarction to ST-segment myocardial infarction. Myocardial ischemia in this context occurs as a result of an abrupt decrease in coronary blood flow and resultant imbalance in the myocardial oxygen supply-demand relationship. Coronary blood flow is further compromised by other mechanisms that increase coronary vascular resistance or reduce coronary driving pressure. The goals of treatment are to decrease myocardial oxygen demand, increase coronary blood flow and oxygen supply, and limit myocardial injury. Treatments are generally divided into disease-modifying agents or interventions that improve hard clinical outcomes and other strategies that can reduce ischemia. In addition to traditional drugs such as β-blockers and inhibitors of the renin-angiotensin-aldosterone system, newer agents have expanded the number of molecular pathways targeted for treatment of ACS. Ranolazine, trimetazidine, nicorandil, and ivabradine are medications that have been shown to reduce myocardial ischemia through diverse mechanisms and have been tested in limited fashion in patients with ACS. Attenuating the no-reflow phenomenon and reducing the injury compounded by acute reperfusion after a period of coronary occlusion are active areas of research. Additionally, interventions aimed at ischemic pre- and postconditioning may be useful means by which to limit myocardial infarct size. Trials are also underway to examine altered metabolic and oxygen-related pathways in ACS. This review will discuss traditional and newer anti-ischemic therapies for patients with ACS, exclusive of revascularization, antithrombotic agents, and the use of high-intensity statins.

  14. C-reactive protein in patients with acute coronary syndrome: association with coronary markers, lipid profile and markers of coagulation

    To determine levels of C-reactive protein (CRP) and its association with coronary markers, lipid profile and markers of coagulation in patients of acute coronary syndrome (ACS). The study was conducted at Shifa college of Medicine and Shifa international hospital for a period of one year (November 2005-December 2006). Patients and Methods: Sixty nine age matched controls and 133 consecutive patients of ACS were included in the study. CRP were measured by immunoturbidometric method, MB fraction of creatine kinase (CK-MB) and Troponin-1 by micro-particle enzyme immunoassay, lipid levels by Colorimetric Enzymatic methods, platelets by celldyn and coagulation markers were measured by CA-50 Sysmax. At admission mean CRP levels, cardiac biomarkers, lipid profile and coagulation markers were significantly increased in patients of ACS versus controls. Within the patients of ACS the mean levels of CRP, CK-MB, Trop I, prothrombin time (PT) and activated partial thromboplastin time (Am) were significantly raised in patients with ST - elevation myocardial infarction (STEMI) and non STEMI (NSTEMI) versus patients of unstable angina (VA). Association between CRP levels and coronary markers, coagulation markers and lipid profile was found to be non significant. The CRP levels were increased in patients with ACS as compared to controls. The CRP levels were insignificantly correlated with coronary markers (CK-MB, Trop I), coagulation markers (platelet count, PT, Am), and lipid profile (cholesterol, triglyceride, HDL and LDL cholesterol) in patients with ACS.

    2016-07-01

    Full Text Available Identification of patients at increased risk of death due to acute coronary syndrome (ACS can add to risk stratification and guide the next step in the management of those patients. Altered HRV has been associated with adverse outcomes in heart disease, but this has not been established in patients with acute chest pain.This study aimed to create a non-invasive, economical and risk-free method in the clinical evaluation and diagnosis of significant CAD among patients with unstable angina.Twenty-four-hour Holter recordings of 100 patients with ACS were initiated within 24 hours of admission at the emergency department; stress ECG was done for all patients while coronary angiography was done only for patients with abnormal stress test. Time domain, frequency domain, and nonlinear HRV were examined.The mean SDNN was statistically significantly lower in patients with abnormal stress test, many time and frequency domain HRV parameters was statistically lower in patients with significant coronary arteries obstruction. HRV measured close to the ACS onset may assist in risk stratification. HRV parameters may provide additional, incremental prognostic information to established assessment guidelines and possible early intervention in those patients.

    Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and/or when urinary output is insufficient after diuretics. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension. PMID:27232927

    2014-12-01

    Full Text Available Background: Cardiovascular disease is the leading cause of mortality in the western world and its treatment should be optimized to decrease severe adverse events. Objective: To determine the effect of previous use of angiotensin-converting enzyme inhibitors on cardiac troponin I measurement in patients with acute coronary syndrome without ST-segment elevation and evaluate clinical outcomes at 180 days. Methods: Prospective, observational study, carried out in a tertiary center, in patients with acute coronary syndrome without ST-segment elevation. Clinical, electrocardiographic and laboratory variables were analyzed, with emphasis on previous use of angiotensin-converting enzyme inhibitors and cardiac troponin I. The Pearson chi-square tests (Pereira or Fisher's exact test (Armitage were used, as well as the non-parametric Mann-Whitney's test. Variables with significance levels of 0.5 ng / mL were high blood glucose at admission (p = 0.0034 and ST-segment depression ≥ 0.5 mm in one or more leads (p = 0.0016. The use of angiotensin-converting inhibitors prior to hospitalization was associated with troponin ≤ 0.5 ng / mL (p = 0.0482. The C-statistics for this model was 0.77. Conclusion: This study showed a correlation between prior use of angiotensin-converting enzyme inhibitors and reduction in the myocardial necrosis marker troponin I in patients admitted for acute coronary syndrome without ST-segment elevation. However, there are no data available yet to state that this reduction could lead to fewer severe clinical events such as death and re-infarction at 180 days.

  1. Effects of continuous administration of clopidogrel before off-pump coronary artery bypass grafting in patients with acute coronary syndrome. A propensity score analysis

    Clopidogrel has become standard treatment after urgent percutaneous coronary revascularization. Due to its enhanced and irreversible platelet inhibition, patients undergoing urgent surgical revascularization have a higher risk of bleeding complications and transfusions. Therefore, the effect of preoperative continuous administration of clopidogrel on the incidence of hemorrhagic complications in patients undergoing off-pump coronary artery bypass surgery with acute coronary syndrome was evaluated. From March 2004 to September 2006, 172 patients with acute coronary syndrome underwent isolated off-pump coronary artery bypass surgery; 70 (40.7%) and 102 (59.3%) of these patients did or did not take clopidogrel before surgery respectively. Seventy patients in each group were matched using propensity scores and associations between preoperative continuous administration of clopidogrel and postoperative bleeding, hemostatic reoperation, blood products received, the need for multiple transfusions and early graft patency by coronary computed tomography were assessed. Univariate analysis showed the continuous clopidogrel group had similar levels of postoperative bleeding for 24 h (601.4±312.6 ml vs 637.2±452.4 ml, p=0.616) and rates of reexploration (1.4% vs 1.4%), perioperative blood transfusion (33.3% vs 34.3%, p>0.05) and platelet transfusion (2.9% vs 7.1%, p=0.44) compared with the non-continuous group. Preoperative continuous administration of clopidogrel did not increase the risk of hemorrhagic complications in patients with acute coronary syndrome undergoing isolated off-pump coronary artery bypass surgery. These findings indicate that surgery after clopidogrel treatment in patients with acute coronary syndrome should not be delayed until platelet function returns to normal because they may have a higher risk of recurrent myocardial ischemic events.

  2. Highly sensitive C-reactive protein and male gender are independently related to the severity of coronary disease in patients with metabolic syndrome and an acute coronary event

    C.M.C. Monteiro

    2010-03-01

    Full Text Available Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP, are related to coronary atherosclerosis, in addition to traditional coronary risk factors. Subjects of both genders aged 30 to 75 years (N = 116 were prospectively included if they had suffered a recent acute coronary syndrome (acute myocardial infarction or unstable angina pectoris requiring hospitalization and if they had metabolic syndrome diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III. Patients were submitted to a coronary angiography and the burden of atherosclerosis was estimated by the Gensini score. The severity of coronary disease was correlated (Spearman’s or Pearson’s coefficient with gender (r = 0.291, P = 0.008, age (r = 0.218, P = 0.048, hsCRP (r = 0.256, P = 0.020, ApoB/ApoA ratio (r = 0.233, P = 0.041, and carotid intima-media thickness (r = 0.236, P = 0.041. After multiple linear regression, only male gender (P = 0.046 and hsCRP (P = 0.012 remained independently associated with the Gensini score. In this high-risk population, male gender and high levels of hsCRP, two variables that can be easily obtained, were associated with more extensive coronary disease, identifying patients with the highest potential of developing new coronary events.

    2006-01-01

    Infliximab is a potent anti-TNF antibody, which is used with great success in Crohn's disease patients. Since its release in clinical practice, several adverse reactions have been observed. The interest in possible consequences of its administration is still high because of the recent introduction of the drug for the long-term maintenance therapy of refractory luminal and fistulizing Crohn's disease. We present a case of acute coronary syndrome (non-STEMI) in a patient with corticoid resistant Crohn's disease after his first dose of infliximab. By reviewing the scant articles that exist in the literature on this topic we made an effort to delineate the possible mechanisms of this phenomenon.

  6. Latest Advancement of Non ST-segment Elevation Acute Coronary Syndrome

    2008-01-01

    Further understanding of the pathphophisyology, advance of the diagnosis instrument and renovation of the risk delamination standard can offer better therapy evidence for the non-ST-segment elevation acute coronary syndrome(NSTE-ACS). Drugs, such as trigeminy antiplatelet drug, prasugrel, fondaparinux and bivalirudin, have brought great clinical effect to the high risk patients. Since the result of the ICTUS test announced and the drug eluting balloon developed, we have reached the newest recognition of how to select a chance for intervention and how to prevent and cure the restenosis of in-stent.

    Full Text Available Background: Some studies have indicated alcohol abuse as one of the contributors to the development of cardiovascular disease, particularly coronary heart disease. However, this relationship is controversial. Objective: To investigate the relationship between post-acute coronary syndrome (ACS alcohol abuse in the Acute Coronary Syndrome Registry Strategy (ERICO Study. Methods: 146 participants from the ERICO Study answered structured questionnaires and underwent laboratory evaluations at baseline, 30 days and 180 days after ACS. The Alcohol Use Disorders Identification Test (AUDIT was applied to assess harmful alcohol consumption in the 12 months preceding ACS (30 day-interview and six months after that. Results: The frequencies of alcohol abuse were 24.7% and 21.1% in the 12 months preceding ACS and six months after that, respectively. The most significant cardiovascular risk factors associated with high-risk for alcohol abuse 30 days after the acute event were: male sex (88.9%, current smoking (52.8% and hypertension (58.3%. Six months after the acute event, the most significant results were replicated in our logistic regression, for the association between alcohol abuse among younger individuals [35-44 year-old multivariate OR: 38.30 (95% CI: 1.44-1012.56 and 45-54 year-old multivariate OR: 10.10 (95% CI: 1.06-96.46] and for smokers [current smokers multivariate OR: 51.09 (95% CI: 3.49-748.01 and past smokers multivariate OR: 40.29 (95% CI: 2.37-685.93]. Conclusion: Individuals younger than 54 years and smokers showed a significant relation with harmful alcohol consumption, regardless of the ACS subtype.

    The prognostic value of gamma-glutamyl transferase (GGT) in patients with acute coronary syndromes (ACS) has been incompletely investigated. We investigated this clinically relevant question in 2,534 consecutive patients with ACS who underwent percutaneous coronary intervention (PCI). GGT activity was measured before PCI procedure in all patients. Statin therapy at hospital discharge was prescribed in 94% of the patients. The primary outcome was 3-year mortality. Patients were divided into 3 groups: the group with GGT in the first tertile (GGT estimates were calculated per SD increase in the logarithmic scale of GGT activity). In conclusion, in contemporary patients with ACS treated with PCI and on statin therapy, elevated GGT activity was associated with the increased risk of all-cause and noncardiac mortality but not with the risk of cardiac mortality.

  10. Curcumin as a novel plaque stabilizing agent in prevention of acute coronary syndrome

    2009-05-01

    Full Text Available "nCurcumin (diferuloylmethane is an active component of the spice turmeric and has been linked with anti-inflammatory and chemopreventive activities. The present hypothesis explained the involvement of anti-inflammatory effects of crcumin in prevention of acute coronary syndromes (ACS (i.e. unstable angina and myocardial infarction. ACS is the leading cause of death in both developed and developing countries. Coronary events often result from thrombi that form because of physical disruption of the atherosclerotic plaque. However, despite lipid lowing therapy with statins, significant numbers of cardiovascular events continue to occur indicating the need for additional agents for atherosclerosis management. We proposed that curcumin therapy can stabilize vulnerable 'rupture-prone' plaques by normalizing plaque properties. Thus, co-administration of curcumin along with other present options may prove to be a useful and potent natural plaque stabilizing approach in the prevention of ACS.

    Full Text Available Background: Ischemic heart disease is defined as inadequate blood flow resulting in decreased oxygenation to the myocardium due to severe narrowing and/or complete blockage of coronary arteries. Although a number of risk factors have been identified over the past several decades, the precise aetiology and mechanisms leading to the development of CAD are not fully understood. These includes abnormal levels of circulating cholesterols with elevated level of LDL-cholesterol and reduced level of HDL-cholesterol, hypertension, cigarette smoking, diabetes mellitus, male gender, post-menopausal state, advanced age, sedentary life style, obesity and a positive family history of premature cardiovascular disease female population. Methods: Our study was aimed to interrogate and to assess the patients presenting with acute coronary syndrome, for the presence of conventional risk factors with special eye on diabetes and to stratify patients with acute coronary syndrome according to their diabetic status (Diabetic vs. non diabetic and also to study pattern of involvement of coronary arteries in diabetic and non-diabetic patients and to stratify patient according to treatment they received PTCA vs. CABG. Results: It was observed that out of 100 patients with diabetes mellitus, 71% patients were having diabetes mellitus. Among the diabetics in this study, STEMI (73.13% was the commonest presentation of ACS. On the other hand amongst diabetics, 58.33% had STEMI. Conclusion: Patients with diabetes mellitus had more dyslipidemia, hypertension and smokers. This group of patients required maximum intervention in the form PTCA and CABG.

  12. Frequency of risk factors in male patients with acute coronary syndrome

    To determine the frequency of risk factors in male patients presenting with acute coronary syndrome. Study Design: Observational study. Place and Duration of Study: Armed Forces Institute of Cardiology and National Institute of Heart Diseases, Rawalpindi, from October 2007 to September 2008. Methodology: Male patients with acute coronary syndrome were included in this study. Patients having angioplasty (PCI), coronary artery bypass surgery, chronic liver and kidney diseases were excluded. Presence of diabetes, smoking, hypertension, dyslipidemia, physical activity, stress, a family history of coronary artery disease (CAD) and medication was documented. Blood pressure, ECG, cardiac enzymes, fasting blood glucose, lipid profile and echocardiography were done within 24 hours of admission. Body mass index and waist circumference were measured. Data was analysed using SPSS-15. Results: A total of 135 male patients of ACS were studied having mean age of 54.26+-11.60 years. Maximum number of patients aged between 51 to 60 years, (n = 41, 31.9%). STEMI (ST-elevation myocardial infarction) was diagnosed in 96 (71.1%) patients, non-STEMI in 12 (8.9%) while 27 (20%) patients were having unstable angina. Smoking was documented in 60 (44%) patients, hypertension in 50 (37%), diabetes in 34 (25.2%) and a family history of premature CAD was recorded in 24 (17.8%) patients. Fifty one (37.8%) patients were overweight (BMI = 25-29.9) while 22 (16.3%) were obese (BMI greater or equal to 30). Waist circumference > 90 cm was found in 86 (63.6%) subjects. Sixty four (47.4%) patients were active physically. Psychosocial stress was documented in 33 (23.75). Hypertension, diabetes and dyslipidemia were the most frequent combinations, observed in 24 (17.9%) subjects. Conclusion: Dyslipidemia, smoking, hypertension and diabetes were most frequent risk factors. Public awareness to control risk factors can reduce the prevalence of CAD. (author)

    2010-07-01

    Full Text Available The management of antithrombotic therapy in atrial fibrillation patients presenting with acute coronary syndrome and/or undergoing percutaneous coronary inter vention/stenting cannot be done according to a regimented common protocol, and stroke and bleeding risk stratification schema should be employed to individualize treatment options. A delicate balance is needed between the prevention of thromboembolism, against recurrent cardiac ischemia or stent thrombosis, and bleeding risk. New guidance from a consensus document of the European Society of Cardiology Working Group on Thrombosis, endorsed by the European Heart Rhythm Association and the European Association ofPercutaneous Cardiovascular Interventions on the management of Antithrombotic Therapy in Atrial Fibrillation Patients Presenting with Acute Coronary Syndrome and/or Undergoing Percutaneous Coronary Intervention/Stenting has sought to clarify some of the major issues and problems surrounding this practice, and will allow clinicians to make much more informed decisions when faced with treating such patients.

  15. Evaluation by multislice computed tomography of atherosclerotic coronary artery plaques in non-culprit, remote coronary arteries of patients with acute coronary syndrome

    Patients with acute coronary syndrome (ACS) frequently have vulnerable plaques in the remote coronary arteries, suggesting that ACS is part of the pan-coronary process. In the present study the computed tomography (CT) plaque density in non-culprit atherosclerotic coronary artery lesions was evaluated by multi-slice computed tomography (MSCT) in patients with ACS and non-ACS. MSCT was performed in 21 patients with ACS and 53 patients with non-ACS: 16 of the 21 ACS patients (76%) and 30 of the non-ACS 53 patients (57%) had non-calcified plaques in the non-culprit coronary arteries (p=0.18). CT-low-density plaques (CT density <68 Hounsfield units (HU)) were more frequent in the ACS group (13/16 patients, 81%) than in the non-ACS group (13/30 patients, 43%, p=0.03). In addition, the CT density of the non-culprit lesion was significantly lower in patients with ACS than in those with non-ACS (44.1±22.9 and 77.3±33.7 HU, respectively). Patients with ACS more frequently had CT-low-density plaques in the non-culprit, remote arteries than those with non-ACS, which suggests that ACS treatment should focus not only on stabilizing the culprit lesion but also on systemic stabilization of non-culprit lesions.

    2012-04-01

    In a prospective cohort study, we evaluated the effect of Helicobacter pylori seropositivity on the risk of future adverse cardiovascular outcomes among patients with acute coronary syndrome (ACS). In 433 patients, IgA and IgG antibodies to H pylori, along with classic risk factors, including hypertension, diabetes, hyperlipidaemia, smoking and family history of coronary artery disease (CAD) were determined. Short and long-term follow-up information on adverse outcomes, defined as recurrence of unstable angina, myocardial infarction, coronary angioplasty, coronary artery bypass graft surgery, and sudden cardiac death was obtained. None of the classic CAD risk factors correlated with incidence of either short- or long-term outcomes. Seropositivity for H pylori was significantly associated with risk of short-term adverse outcomes, and independently predicted their incidence in multivariate regression (R = 3.05, p < 0.001). Results failed to show such an association between H pylori seropositivity and long-term adverse outcomes. H pylori infection may affect short-term prognosis in patients with ACS. Randomised trials are needed to evaluate the role of H pylori eradication in these patients. PMID:22555636

    2016-04-01

    Pheochromocytomas are neuroendocrine tumors, and its cardiac involvement may include transient myocardial dysfunction, acute coronary syndrome (ACS), and even ventricular arrhythmias.A patient was referred for evaluation of stuttering chest pain, and his electrocardiogram showed T-wave inversion over leads V1 to V4. Coronary angiography showed 90% stenosis in the mid-left anterior descending coronary artery (LAD), which was stented. Five days later, the patient had ventricular tachycardia, and severe hypertension, remarkable blood pressure fluctuation between 224/76 and 70/50 mm Hg. The patient felt abdominal pain and his abdominal ultrasound showed suspicious right adrenal gland tumor. Enhanced computed tomography of adrenal gland conformed that there was a tumor in right adrenal gland accompanied by an upset level of aldosterone.The tumor was removed by laparoscope, and the pathological examination showed pheochromocytoma. After the surgery, the blood pressure turned normal gradually. There was no T-wave inversion in lead V1-V4. Our case illustrates a rare pheochromocytoma presentation with a VT and resembling ACS. In our case, the serious stenosis in the mid of LAD could be explained by worsen the clinical course of myocardial ischemia or severe coronary vasospasm by the excessive amounts of catecholamines released from the tumor. Coronary vasospasm was possible because he had no classic coronary risk factors (e.g. family history and smoking habit, essential hypertension, hyperglycemia and abnormal serum lipoprotein, high body mass index). Thus, pheochromocytoma was missed until he revealed the association of his symptoms with abdominalgia.As phaeochromocytomas that present with cardiovascular complications can be fatal, it is necessary to screen for the disease when patients present with symptoms indicating catecholamine excess.

  19. Clinical manifestation as acute coronary syndrome without electrocardiographically ischemia:a clue for aortic dissection

    Hung Yi Chen

    2015-01-01

    Aortic dissection is a critical condition requiring immediate assessment and management. Clinical presentation is commonly associated with severe chest pain and high blood pressure. However, misdiagnosis is frequent because of various features. We presented a case of 51-year-old woman who complained of dyspnea for 3 d after she experienced back pain for one week. She was presented with severe respiration distress with impending respiration failure on arrival to our hospital. Her chest X-ray showed cardiomegaly with acute pulmonary edema. The laboratory data revealed elevated cardiac enzyme and electrocardiography demonstrated sinus tachycardia. She was hospitalized under the initial diagnosis of acute coronary syndrome. The patient remained hemodynamically stable, and experienced one episode of chest discomfort. After electrocardiography, she was found with bigeminy ventricular premature beats without ST-T change. Follow-up cardiac enzyme demonstrated progressive declined. Cardiac catheterization was performed on the third day of admission, and coronary angiography revealed large intimal flap on aortic root with bilateral coronary artery involvement. Surgical management was arranged after immediate chest computed tomography study.

  1. Thinking styles and doctors' knowledge and behaviours relating to acute coronary syndromes guidelines

    Sladek, Ruth M; Bond, Malcolm J; Huynh, Luan T; Chew, Derek PB; Phillips, Paddy A

    2008-01-01

    Background How humans think and make decisions is important in understanding behaviour. Hence an understanding of cognitive processes among physicians may inform our understanding of behaviour in relation to evidence implementation strategies. A personality theory, Cognitive-Experiential Self Theory (CEST) proposes a relationship between different ways of thinking and behaviour, and articulates pathways for behaviour change. However prior to the empirical testing of interventions based on CEST, it is first necessary to demonstrate its suitability among a sample of healthcare workers. Objectives To investigate the relationship between thinking styles and the knowledge and clinical practices of doctors directly involved in the management of acute coronary syndromes. Methods Self-reported doctors' thinking styles (N = 74) were correlated with results from a survey investigating knowledge, attitudes, and clinical practice, and evaluated against recently published acute coronary syndrome clinical guidelines. Results Guideline-discordant practice was associated with an experiential style of thinking. Conversely, guideline-concordant practice was associated with a higher preference for a rational style of reasoning. Conclusion Findings support that while guidelines might be necessary to communicate evidence, other strategies may be necessary to target discordant behaviours. Further research designed to examine the relationships found in the current study is required. PMID:18439250

    2014-01-01

    Full Text Available Acute coronary syndrome is one of the leading causes of morbidity and mortality worldwide , hyperlipidemias being a major predisposing factor. Cardiac Troponin T (cTnT is one of the most sensitive and specific biomarkers of myocardial injury. The aim of the study was to evaluate the relationship among TnT levels and lipid profiles of different age groups of patients with ACS , and to determine if any the association of age with lipid profile and TnT levels. The lipid profiles and TnT levels were de termined in 464 patients with acute coronary syndrome. Depending upon age , the patients were divided into groups 1 , 2 and 3 (49 ≤ , 50 - 69 and ≤ 70 years respectively. Increasing age was found to be associated with fall in mean levels of total cholesterol , LD L , triglycerides and TnT. Our study suggested that among patients with ACS , there exists a relation between age , lipid components and TnT levels. TnT is known to be an independent predictor of the outcome of myocardial ischemia. Further studies are therefo re required to ascertain the validity of TnT as a prognostic cardiac biomarker among the elderly

  3. Acute coronary syndromes in low- and middle-income countries: Moving forward.

    Seligman, Benjamin; Vedanthan, Rajesh; Fuster, Valentin

    2016-08-01

    Cardiovascular disease remains the leading cause of death worldwide, particularly in low- and middle-income countries (LMICs), with substantial mortality from acute coronary syndromes. These deaths, when compared against high-income countries, occur at younger ages, and, beyond the lives lost, often result in economic privation for families deprived of a breadwinner and indebted by the oftentimes catastrophic cost of inpatient medical care. This burden will likely grow in scale in the years ahead as more countries pass through the epidemiologic transition. Billions around the world are beginning to experience the comforts that even modestly increased incomes can provide, including diets high in fats and sugars, more sedentary lifestyles, and tobacco and alcohol use and abuse. Health care systems in many of these countries are ill-equipped to prevent the harms caused by these lifestyles, as well as treat the acute coronary syndromes that result from them-including insufficient access to appropriate facilities and medications, difficulties with transport, and low awareness of the symptoms and need for emergent evaluation.

    Early risk stratification in patients with non-ST elevation acute coronary syndromes (NSTE-ACS) is important since the benefit from more aggressive and costly treatment strategies is proportional to the risk of adverse clinical events. In the present study we assessed whether hybrid single photon emission computed tomography (SPECT)/coronary computed tomography angiography (CCTA) technology could be an appropriate tool in stratifying patients with NSTE-ACS. SPECT/CCTA was performed in 90 consecutive patients with NSTE-ACS. The Thrombolysis in Myocardial Infarction risk score (TIMI-RS) was used to classify patients as low- or high-risk. Imaging was performed using SPECT/CCTA to identify haemodynamically significant lesions defined as >50% stenosis on CCTA with a reversible perfusion defect on SPECT in the corresponding territory. CCTA demonstrated at least one lesion with >50% stenosis in 35 of 40 high-risk patients (87%) as compared to 14 of 50 low-risk patients (35%; TIMI-RS <3; p <0.0001). Of the 40 high-risk and 50 (16%) low-risk TIMI-RS patients, 16 (40%) and 8 (16%), respectively, had haemodynamically significant lesions (p = 0.01). Patients defined as high-risk by a high TIMI-RS, a positive CCTA scan or both (n = 45) resulted in a sensitivity of 95%, specificity of 49%, PPV of 35% and NPV of 97% for having haemodynamically significant coronary lesions. Those with normal perfusion were spared revascularization procedures, regardless of their TIMI-RS. Noninvasive assessment of coronary artery disease by SPECT/CCTA may play an important role in risk stratification of patients with NSTE-ACS by better identifying the subgroup requiring intervention.

    Coronary artery disease is one of the most rampant non-communicable diseases in the world. It begins indolently as a fatty streak in the lining of the artery that soon progresses to narrow the coronary arteries and impair myocardial perfusion. Often the atherosclerotic plaque ruptures and causes sudden thrombotic occlusion and acute ST-elevation myocardial infarction (STEMI), non-ST-elevation MI (NSTEMI) or unstable angina (UA). This phenomenon is called acute coronary syndrome (ACS) and is the leading cause of death not only in Malaysia but also globally. In order for us to tackle this threat to the health of our nation we must arm ourselves with reliable and accurate information to assess current burden of disease resources available and success of current strategies. The acute coronary syndrome (ACS) registry is the flagship of the National Cardiovascular Disease Database (NCVD) and is the result of the dedicated and untiring efforts of doctors and nurses in both public and private medical institutions and hospitals around the country, ably guided and supported by the National Heart Association, the National Heart Foundation, the Clinical Research Centre and the Ministry of Health of Malaysia. Analyses of data collected throughout 2006 from 3422 patients with ACS admitted to the 12 tertiary cardiac centres and general hospitals spanning nine states in Malaysia in this first report has already revealed surprising results. Mean age of patients was 59 years while the most consistent risk factor for STEMI was active smoking. Utilization of medications was high generally. Thirty-day mortality for STEMI was 11%, for NSTEMI 8% and UA 4%. Thrombolysis (for STEMI only) reduced in-hospital and 30-day mortality by nearly 50%. Percutaneous coronary intervention or PCI also reduced 30-day mortality for patients with non-ST elevation MI and unstable angina. The strongest determinants of mortality appears to be Killip Class and age of the patient. Fewer women received

  11. Treatment disparities in acute coronary syndromes, heart failure, and kidney disease.

    McCullough, Peter A; Maynard, Robert C

    2011-01-01

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time. PMID:21625092

  14. An Unusual Aneurysm of the Main Pulmonary Artery Presenting as Acute Coronary Syndrome

    A 70-year old man presented with retrosternal chest pain. His electrocardiogram showed nonspecific T wave changes. Cardiac-specific troponin I (cTnI) was elevated. His condition was managed as acute coronary syndrome, following which he had two minor episodes of hemoptysis. A CT pulmonary angiogram showed no evidence of pulmonary embolism, but a large mass lesion was seen in the mediastinum. Echocardiography and cardiac MRI demonstrated a large solid mass, arising from the right ventricular outflow tract and causing compression of the main pulmonary artery (MPA). The differential diagnosis included pericardial and myocardial tumors and clotted aneurysm of the MPA. At surgery, a clotted aneurysmal sac was identified originating from the MPA and the defect was healed. Aneurysms of the MPA are rare. They most commonly present with dyspnea and chest pain. Compression of surrounding structures produces protean manifestations. A high index of suspicion coupled with imaging modalities establishes the diagnosis. Blunt trauma to the chest, at the time of an accident 4 years previously, may explain this aneurysm. The patient's presentation with chest pain was probably due to compression and/or stretching of surrounding structures. Coronary artery compression simulating acute coronary syndrome has been documented in the literature. The rise in cTnI may have been due to right ventricular strain, as a result of right ventricular outflow obstruction by the aneurysm. This has not been reported previously in the literature. The saccular morphology and narrow neck of the aneurysm predisposed to stagnation leading to clotting of the lumen and healing of the tear, which caused the diagnostic difficulty

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

  20. Cardiac CT diagnosis in acute coronary syndrome. Significance of delayed enhancement effect in myocardium

    Authors have found that the effect in the title (DEE) exists in cardiac CT images due to the contrasting agent used for percutaneous coronary intervention (PCI) done shortly after the onset of acute coronary syndrome (ACS). To confirm the finding, they compared images of the cardiac CT and blood flow single photon emission computed tomography (SPECT) obtained several days after ACS. The cardiac CT images of 17 patients (M 15, F 2; average age 63.6 y) with ACS were obtained 20-30 min after the successfully attained emergent enhanced PCI, with the 4-row multi detector low CT (MDCT) machine Aquilion (Toshiba) in synchronization to R-R interval for processing to multiplanar reconstructed (MPR) images. Thereafter (5.5 days in average), myocardial SPECT was conducted with 99mTc-tetrofosmin (740 MBq), of which images were also processed to MPR ones. The CT and SPECT images were compared in coronary arterial territories assigned to 17 segments in the left ventricle and to 20 areas in the Bull's-eye Map. Findings due to DEE in the former CT images were confirmed well correspondent with the lesion found in the latter SPECT, indicating that DEE is a useful tool for evaluation of ACS severity. (R.T.)

    2005-03-01

    Full Text Available Abstract Background The present study GREECS was conducted in order to evaluate the annual incidence of acute coronary syndromes (ACS and to delineate the role of clinical, biochemical, lifestyle and behavioral characteristics on the severity of disease. In this work we present the design, methodology of the study and various baseline characteristics of people with ACS. Methods/Design A sample of 6 hospitals located in Greek urban and rural regions was selected. In these hospitals we recorded almost all admissions due to ACS, from October 2003 to September 2004. Socio-demographic, clinical, dietary, psychological and other lifestyle characteristics were recorded. 2172 patients were included in the study (76% were men and 24% women. The crude annual incidence rate was 22.6 per 10,000 people and the highest frequency of events was observed in winter. The in-hospital mortality rate was 4.3%. The most common discharged diagnosis for men was Q-wave MI, while for women it was unstable angina. Discussion This study aims to demonstrate current information about the epidemiology of patients who suffer from ACS, in Greece.

  2. Polyvascular Disease in Patients Presenting with Acute Coronary Syndrome: Its Predictors and Outcomes

    Hassan Al Thani

    2012-01-01

    Full Text Available We evaluated prevalence and clinical outcome of polyvascular disease (PolyVD in patients presenting with acute coronary syndrome (ACS. Data for 7689 consecutive ACS patients were collected from the 2nd Gulf Registry of Acute Coronary Events between October 2008 and June 2009. Patients were divided into 2 groups (ACS with versus without PolyVD. All-cause mortality was assessed at 1 and 12 months. Patients with PolyVD were older and more likely to have cardiovascular risk factors. On presentation, those patients were more likely to have atypical angina, high resting heart rate, high Killip class, and GRACE risk scoring. They were less likely to receive evidence-based therapies. Diabetes mellitus, renal failure, and hypertension were independent predictors for presence of PolyVD. PolyVD was associated with worse in-hospital outcomes (except for major bleedings and all-cause mortality even after adjusting for baseline covariates. Great efforts should be directed toward primary and secondary preventive measures.

  3. Antithrombotic strategies in non-ST elevation acute coronary syndromes: focus on bivalirudin.

    Nikolsky, Eugenia; Stone, Gregg W

    2007-07-01

    Acute coronary syndromes (ACS) are a common presentation of coronary artery disease, accounting for more than one million hospital admissions in the US annually. Owing to high rates of mortality and reinfarction, ACS represent a major public health concern. The following review discusses the pathogenesis of ACS and optimal approaches for the management of patients with ACS, with special focus on new antithrombotic strategies, including the direct thrombin inhibitor bivalirudin. Bivalirudin has several notable mechanistic advantages compared with unfractionated heparin, including activity against clot-bound thrombin, inhibition of thrombin-induced platelet activation, short plasma half-life in patients with normal or mildly impaired renal function (25 minutes), and linear pharmacokinetics less affected by plasma proteins and renal insufficiency. These properties provide a more predictable inhibition of coagulant activity than unfractionated heparin, with less degree of inter-patient variability in anticoagulation response. The findings from the several clinical trials assessing safety and efficacy of bivalirudin are analyzed in detail, including the recent randomized controlled Acute Catheterization and Urgent Intervention Triage Strategy (ACUITY) trial. Based on the results of the ACUITY trial, a newer streamlined strategy for the invasive treatment of moderate- and high-risk patients with ACS is discussed. PMID:19804226

  4. Analysis of clinical application on determining serum inflammatory cytokines levels in patients with acute coronary syndrome

    Objective: To evaluate analysis of clinical application on determining serum inflammatory cytokines levels in patients with acute coronary syndrome (ACS). Methods: The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), high-sensitive C-reaction protein (hs-CRP) (with high-sensitive enzyme immunoassay) and tumor necrosis factor-α (TNF-α) (with radioimmunoassay) in serum were determined in 112 patients with ACS, 32 patients with stable angina pectoris (SAP) and 42 normal controls as well as did compared analysis. Results: The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels in 112 patients with ACS were obviously higher than those in 42 controls (P all0.05), serum hs-CRP level was increased only (P<0.05). The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels in 46 patients with acute myocardial infraction (AMI) were prominently higher than those in 66 patients with unstable angina pectoris (UAP) and in 32 patients with SAP. The serum IL-1β, IL-6, IL-8, TNF-α and hs-CRP levels with advanced degree SAP, UAP and AMI were increased. Conclusion: In the severity of the patients with SAP, UAP, AMI, the determination of serum inflammatory cytokines level were a good and important index, so that it was referential for heart coronary events happened.

  5. Evaluation of Some Inflammatory and Biochemical Markers in Acute Coronary Syndrome

    The term acute coronary syndrome (ACS) encompasses a range of thrombotic coronary artery diseases, including unstable angina (UA) and both ST-segment elevation (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Bio markers play an important role in the diagnosis of non-ST-elevation ACS (NSTE-ACS) including unstable angina and non-STEMI. Among these, cardiac troponin and creatine phosphokinase myocardial band appeared to be the most sensitive and specific markers of myocardial injury. The important role of inflammatory processes in the development and progression of atherosclerosis has been clearly established. Different circulating inflammatory bio markers indicating the instability of atherosclerotic plaque have been identified and serve as diagnostic tools for the identification of patients with unstable angina or acute myocardial infarction and to identify risk patients. The present study was carried out on twenty patients with (NSTE-ACS). The level of serum troponin I (cTnI), creatine phosphokinase-total (CPK-T), myocardial band of creatine phosphokinase (CPK-MB), pregnancy associated plasma protein-A (PAPP-A) and highly sensitive C-reactive protein (hsCRP) were determined. The results showed increase in the level of cardiac bio markers (cTnI, CPK-MB, CPK-T) and inflammatory markers (PAPP-A, hsCRP). It could be concluded that the increase in inflammatory markers correlate especially PAPP-A in NSTE-ACS with the increase of cardiac bio markers

    2012-01-01

    Over the years there has been considerable improvement in the clinical outcomes of patients treated for acute coronary syndrome (ACS). Despite a significant reduction in acute mortality, a large percentage of patients post ACS continue to experience adverse cardiovascular (CV) events, with high long-term mortality rates and overall suboptimal medical management. Long-term risk prediction tools rely on traditional CV risk factors and are developed and validated in specific populations. Establi...

    Pheochromocytoma is a tumor arising from neuroectodermal chromaffin tissues in the adrenal gland or extra-adrenal paraganglia (paragangliomas). hTe prevalence of the tumor is 0.1%-0.6% in the hypertensive population, of which 10%-20%are malignant. Pheochromocytoma produces, stores, and secretes catecholamines, as well as leads to hypertensive crisis, arrhythmia, angina, and acute myocardial infarction without coronary artery diseases. We report a case of acute coronary syndrome (ACS) with a ifnal diagnosis of multiple endocrine neoplasia with pheochromocytoma and medullary thyroid carcinoma (MTC).

    2013-10-01

    Full Text Available Aim: In this study we aimed to compare depression and anxiety levels of patients admitted for acute coronary syndrome (ACS with patients followed for stable coronary artery disease in outpatient clinics and control group without coronary artery disease. Material and Method: Study population was composed of 300 patients. Firstly all patients underwent standardized mini mental test and patients whose test scores were under 23 were excluded and patients whose scores were 23 or higher were included in the study. After the demograhic characteristics of patients had been recorded all patients were administered the following scales: Geriatric Depression Scale( GDS, Beck Depression Inventory(BDI, Beck Anxiety Inventory(BAI, State and Trait Anxiety Inventory(STAI 1 and STAI 2. The scores obtained from these scales were compared between all three groups. Results: All test scores were significantly higher in ACS group (p<0.001.In ACS group GDS, BDI and BAI scores were higher in male patients compared to females (p<0.05. When ACS group was divided as ST elevation myocardial infarction (STEMI, Non ST elevation myocardial infarction and unstable angina pectoris the test scores were higher in STEMI subgroup but the relation was not statistically significant. The hospitalisation period length was found to be significantly related to all test scores in patients with ACS (p<0,001. Discussion: Depression and and levels of patients with ACS syndrome must be surely evaluated. This will help us both to improve life quality of these patients and decrease mortality and morbidity of these patients by diagnosing depression and anxiety disorders and treating them on time.

    Context Depression is a consistent predictor of recurrent events and mortality in ACS patients, but it has 2 core diagnostic criteria with distinct biological correlates—depressed mood and anhedonia. Objective To determine if depressed mood and/or anhedonia (loss of pleasure or interest) predict 1-year medical outcomes for patients with Acute Coronary Syndrome (ACS). Design Observational cohort study of post-ACS patients hospitalized between May 2003 and June 2005. Within one week of admission, patients underwent a structured psychiatric interview to assess clinically impairing depressed mood, anhedonia, and major depressive episode (MDE); also assessed were the Global Registry of Acute Coronary Events risk score, Charlson comorbidity index, left ventricular ejection fraction, antidepressant use, and depressive symptom severity. Setting Coronary care and cardiac care step-down units of 3 university hospitals in New York and Connecticut. Participants Consecutive sample of 453 ACS patients (aged 25–93 years; 42% women). Main Outcomes Measures All-cause mortality (ACM) and documented major adverse cardiac events (MACE; myocardial infarction, hospitalization for unstable angina, or urgent revascularization) were actively surveyed for 1 year after admission. Results There were 67 events (16 deaths and 51 MACE; 14.8%). 108 (24%) and 77 (17%) patients with anhedonia and depressed mood, respectively. After controlling for sex, age, and medical covariates, anhedonia (adjusted hazard ratio, 1.58; 95% confidence interval, 1.16–2.14; P<.01) and MDE (adjusted hazard ratio, 1.48; 95% confidence interval, 1.07–2.04; P=.02) were significant predictors of combined MACE/ACM, but depressed mood was not. Anhedonia continued to significantly predict outcomes controlling for MDE diagnosis and depressive symptom severity, each of which were no longer significant. Conclusions Anhedonia identifies risk for MACE/ACM beyond that of established medical prognostic indicators

    Full Text Available The final most common pathway for the majority of coronary artery disease is occlusion of a coronary vessel. Under normal conditions, antithrombin III (AT III, protein C, and protein S as an active protein C cofactor, are natural anticoagulants (hemostatic control that balances procoagulant activity (thrombin antithrombin complex balance to prevent thrombosis. If the condition becomes unbalanced, natural anticoagulants and the procoagulants can lead to thrombosis. Thirty subjects with acute coronary syndrome (ACS were studied for the incidence of antithrombin III (AT III, protein C, and protein S deficiencies, and the result were compare to the control group. Among patients with ACS, the frequency of distribution of AT-III with activity < 75% were 23,3% (7 of 30, and only 6,7% ( 2 of 30 in control subject. No one of the 30 control subject have protein C activity deficient, in ACS with activity < 70% were 13,3% (4 of 30. Fifteen out of the 30 (50% control subjects had protein S activity deficiency, while protein S deficiency activity < 70% was found 73.3.% (22 out of 30. On linear regression, the deterministic coefficient of AT-III activity deficiency to the development ACS was 13,25 %, and the deterministic coefficient of protein C activity deficient to the development of ACS was 9,06 %. The cut-off point for AT-III without protein S deficiency expected to contribute to the development of vessel disease was 45%. On discriminant analysis, protein C activity deficiency posed a risk for ACS of 4,5 greater than non deficient subjects, and AT-III activity deficiency posed a risk for ACS of 3,5 times greater than non deficient subjects. On binary logistic regression, protein S activity acted only as a reinforcing factor of AT-III activity deficiency in the development of ACS. Protein C and AT III deficiency can trigger ACS, with determinant coefficients of 9,06% and 13,25% respectively. Low levels of protein C posed a greater risk of

    2013-01-01

    We assessed the prevalence of unrecognized diabetes mellitus (DM) in patients with acute coronary syndrome (ACS) as determined by elevated glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and random plasma glucose (RPG) levels. This prospective study recruited 583 patients admitted with ACS without previous diagnosis of DM during 1-year period. Glycosylated hemoglobin was checked for most patients especially those with high values of FPG and or RPG. Patients were classified according to their glycemic state into 123 (21.1%) with DM, 82 (14.1%) with prediabetes, and 57(9.8%) with stress hyperglycemia, while 321 (55%) were classified as nondiabetics. Glycosylated hemoglobin estimation in the setting of ACS was helpful in the diagnosis of DM to eliminate the effect of stress-induced hyperglycemia that might accompany this condition. PMID:22550348

    Ravshanbek Kurbanov

    2011-03-01

    Full Text Available The paper describes features history, risk factors and hospital management of acute coronary syndrome (ACS in women of the Central Asia (829 ACS patients are included, and also comparison of hospital outcomes of ACS in groups of men and women.ACS in women in the Central Asia comprises features as more non Q-wave myocardial infarction frequency, smaller adherence to treatment of dyslipidemia, more obesity degrees. Women arrive to hospital average in 4 hours after men; have more percent of the atypical form. In-hospital outcomes in men and women significantly did not differ because of general tendency to late arriving to the hospital and small quantity of revascularization procedures. The reasons of differences between men and women in the region are mostly connected to social sphere (late arriving, non-treated dyslipidemia than to physiological peculiarities.

  13. Historical perspective and contemporary management of acute coronary syndromes: from MONA to THROMBINS2.

    Kline, Kristopher P; Conti, C Richard; Winchester, David E

    2015-01-01

    Acute coronary syndrome (ACS) remains a major burden on morbidity and mortality in the United States. Medical professionals and students often use the mnemonic 'MONA' (morphine, oxygen, nitroglycerin and aspirin) to recall treatments for ACS; however, this list of therapies is outdated. We provide a historical perspective on 'MONA,' attempt to uncover its origin in the medical literature, and demonstrate the myriad changes that have occurred over the last 50 years of ACS management. We have developed a novel mnemonic, 'THROMBINS2' (thienopyridines, heparin/enoxaparin, renin-angiotensin system blockers, oxygen, morphine, beta blocker, intervention, nitroglycerin, statin/salicylate) to help bedside clinicians recall all the elements of contemporary ACS management. We demonstrate the mortality benefit for each component of contemporary ACS management, correlating the continued improvement with historical data on mortality after myocardial infarction. We encourage providers to utilize this mnemonic to explore options and guide treatments in ACS patients. PMID:26457728

    2016-05-01

    Full Text Available Review is devoted to the value of the use of highly sensitive troponin (hs-cTn tests in the diagnosis of acute coronary syndrome. The classification of the Tn-tests depending on their sensitivity is presented. The possible reasons of troponins appearance in blood of healthy people are shown. Authors consider a 3-hour algorithm for myocardial infarction (MI diagnostic, recommended by the expert group in 2012. Study results of 2011-2015 years are presented as the basis for the development of a one-hour MI diagnostic algorithm, recommended by the European Society of Cardiology in 2015. Authors discuss the results of studies showing that modern HS-cTnt tests (together with ECG assessment are capable to diagnose MI in the early stages. They significantly increase the number of identified MI, especially MI without ST segment elevation, as well as identify the group of patients with subsequent favorable prognosis.

  16. Characterization of the asynergic myocardium in acute coronary syndrome using simultaneous dual radionuclide emission computed tomography

    Phantom and clinical studies were undertaken to determine the value of dual SPECT with Tl-201 and Tc-99m pyrophosphate using a simultaneous collection method in evaluating tissue characterization of ischemic myocardium. Phantom experiments revealed that the residual myocardium was detected from the severity of Tl-201 defect images; the influence of cross talk between two radionuclides was negligible; when the Tc-99m layer was located within 50% inside the phantom wall and the other space was filled with Tl-201 solution, the Tc-99m layer was visualized inwardly more clearly than the Tl-201 layer; and transmural infarction 2 to 2.5 cm in diameter was visualized as the total defect of Tl-201. Taking these results into account, scintigraphic characteristics in 84 patients with acute coronary syndrome were evaluated. Seventeen patients in whom asynergy had nearly resolved in the chronic phase were defined as the group of reversible ischemic myocardial damage. Tl-201 uptake in ischemic lesions was improved in the chronic phase when reinfarction was not seen. Both reduced uptake of Tl-201 and Tc-99m uptake in the subendocardial segment were seen in 43% for nontransmural infarction. Total defect of Tl-201 along with transmural uptake of Tc-99m was the most common for transmural infarction. For unstabler angina pectoris, there was no evidence of Tc-99m PYP uptake. Reduced or normal uptake of Tl-201 combined with negative Tc-99m uptake were dominant for reversible ischemic myocardial damage. Patients having relatively good recovery had a significantly higher prevalence of reduced Tl-201 uptake and subendocardial uptake of Tc-99m and a significantly lower prevalence of the total defect of Tl-201 and transmural uptake of Tc-99m. In conclusion, dual SPECT is useful for predicting reversibility in the early stage of acute coronary syndrome. (N.K.)

  17. Fondaparinux and acute coronary syndromes: update on the OASIS 5–6 studies

    François Schiele

    2010-03-01

    Full Text Available François SchieleDepartment of Cardiology, University Hospital Jean-Minjoz, Besançon, FranceAbstract: Anticoagulant therapy is a major component in the management of acute coronary syndromes (ACS. Four anticoagulant agents are currently commercially available for ACS, namely unfractionated heparin (UFH, enoxaparin, bivalirudin and fondaparinux. We describe the advantages of fondaparinux and the reasons that have hampered its uptake into routine management of ACS. Fondaparinux was shown to be efficacious in the prevention of deep vein thrombosis vs low-molecular-weight heparins, while in the setting of venous thrombo-embolic disease, it was shown to be noninferior to enoxaparin and UFH. Two pivotal studies have demonstrated the efficacy of fondaparinux as an anticoagulant in the setting of ACS, namely OASIS-5 in non-ST elevation ACS, and OASIS-6 in ST elevation myocardial infarction (MI. In OASIS-5, fondaparinux was shown to be noninferior to enoxaparin in terms of death, MI or refractory ischemia at 9 days. Furthermore, a 50% reduction in bleeding complications was obtained with fondaparinux vs enoxaparin, leading to a risk reduction for death. In OASIS-6, fondaparinux was shown to be superior to the comparator (UFH or placebo. European and North American guidelines give fondaparinux a Grade 1A and 1B recommendation respectively, but uptake of fondaparinux in routine practice has been slow. We explore reasons for this, such as prevailing doubts about the efficacy of fondaparinux in the setting of angioplasty, the problem of catheter thrombosis, and the lack of antidote in case of bleeding complications. With the exception of primary angioplasty, fondaparinux is as effective as enoxaparin or UFH, but is also associated with a considerable reduction in bleeding complications, and thus, an undeniable net clinical benefit.Keywords: fondaparinux, OASIS, acute coronary syndromes

    Objective To study the impact of national economic and human development status on patient profiles and outcomes in the setting of acute coronary syndrome (ACS). Methods We conducted a retrospective analysis of the Targeted Platelet Inhibition to Clarify the Optimal Strategy to Medically Manage Acute Coronary Syndromes trial (TRILOGY ACS) population (51 countries; 9301 patients). Outcome measures compared baseline characteristics and clinical outcomes through 30 months by 2010 country-level United Nations Human Development Indices (HDIs) and per-capita gross national income. Results TRILOGY ACS enrolled 3659 patients from 27 very-high HDI countries, 3744 from 18 high-HDI countries and 1898 from 6 medium-HDI countries. Baseline characteristics of groups varied significantly, with the medium-HDI group having a lower mean age (63.0 years, vs 65.0 and 68.0 years for high-HDI and very-high HDI, respectively; pGlobal Registry of Acute Coronary Events risk score and lower rate of non-ST-segment elevation myocardial infarction (58.0%, vs 62.2% and 83.9% among high-HDI and very-high HDI, respectively). Medium-HDI and high-HDI patients had lower unadjusted 30-month rates for the composite of cardiovascular death/myocardial infarction/stroke (17.6%, 16.9% and 23.1% for medium-HDI, high-HDI and very-high HDI, respectively); this difference disappeared after adjusting for baseline characteristics. Adjusted HRs for the composite endpoint were lower in lower-income/middle-income countries vs upper-income/middle-income (0.791(95% CI 0.632 to 0.990)) and high-income countries (0.756 (95% CI 0.616 to 0.928)), with differences largely attributable to myocardial infarction rates. Conclusions Clinical patient profiles differed substantially by country HDI groupings. Lower unadjusted event rates in medium-HDI countries may be explained by younger age and lower comorbidity burden among these countries’ patients. This heterogeneity in patient recruitment across country HDI

  19. Asymptomatic acute ischemic stroke after primary percutaneous coronary intervention in patients with acute coronary syndrome might be caused mainly by manipulating catheters or devices in the ascending aorta, regardless of the approach to the coronary artery

    Asymptomatic acute ischemic stroke (aAIS) following primary percutaneous coronary intervention (p-PCI) in patients with acute coronary syndrome (ACS) has not been studied in detail. Of 75 patients who underwent p-PCI, 26 (34.7%) developed aAIS as determined by diffusion-weighted magnetic resonance imaging (MRI). Including the approach to the coronary artery (via lower limb or right upper limb), 23 factors were compared between patients with (n=26) and without (n=49) aAIS. Age, hypertension, smoking, plasma glucose levels, Killip grade, right coronary artery (RCA) as culprit vessel, percutaneous coronary intervention (PCI) time, and the frequency of device insertion into the coronary artery differed in a statistically significant manner. However, multivariate analysis showed that the RCA (odds ratio 3.477) and the frequency of device insertion (1.375) were independent factors linked to the incidence of aAIS. Moreover, anterior or posterior location and left or right cerebral circulation of aAIS were equivalent in both approaches. Cranial MRI images following emergency PCI revealed that 34.7% of the patients with ACS had aAIS that might be caused by manipulating the catheter or devices in the ascending aorta, micro-air bubble embolism during injection, or micro-thrombus embolism derived from the ACS lesions during the PCI procedure.

    The aim of this study was to develop a method for the identification of global weather parameters and patient characteristics associated with a type of heart attack in which there is a sudden partial blockage of a coronary artery. This type of heart attack does not demonstrate an elevation of the ST segment on an electrocardiogram and is defined as a non-ST elevation acute coronary syndrome (NSTE-ACS). Data from the Global Summary of the Day database was linked with the enrollment and baseline data for a phase III international clinical trial in NSTE-ACS in four 48-h time periods covering the week prior to the clinical event that prompted enrollment in the study. Meteorological events were determined by standardizing the weather data from enrollment dates against an empirical distribution from the month prior. These meteorological events were then linked to the patients' geographic region, demographics and comorbidities to identify potential susceptible populations. After standardization, changes in temperature and humidity demonstrated an association with the enrollment event. Additionally there appeared to be an association with gender, region and a history of stroke. This methodology may provide a useful global insight into assessing the biometeorologic component of diseases from international data.

  2. The measurement of serum fibrinogen levels in patients with acute coronary syndrome

    Serum fibrinogen level (SF) is thought to be one of the risk factors for coronary artery disease (CAD). The purpose of this study was to measure the SFL in patients with acute coronary syndrome (ACS). This study was performed in patients with ACS, admitted in Shahid Beheshti Hospital, Babol, Iran, from February 2005 to June 2006. Two hundred patients with ACS were divided into 4 groups: Group I - ST elevated myocardial infarction (STEMI); Group II - non-ST elevated myocardial infarction (NSTEMI), Group III - unstable angina (U/A) with ST-T change and Group IV: U/A without ST-T change. Each group includes 50 patients. Twenty-four hours after admission, the SFL was measured using chromatography methods. The data were collected and analyzed. The mean SFL per mg/dl in each group are Group I - 377.8+-28, Group II - 417.2+-26.8, Group III - 335.4+-19.8 and Group IV - 305.1+-13.8. The SFL in Group II was significantly higher in the other group (p=0.002). The SFL in Group II was higher than in Group III (p=0.02) and much higher than in Group IV (p=0.000). The SFL in Group III was more than in Group IV (p=0.018). The results show that SFL is an important marker in patients with ACS, with ST-T change. (author)

  3. Evaluation the role of myocardial perfusion of MRI and MR cine in acute coronary syndrome

    Objective: To evaluate the role of comprehensive cardiac MRI (CMRI) in diagnosis of patients with coronary artery disease (CAD). Methods; 55 patients with acute coronary syndrome underwent MR imaging 3-6 months after the reperfusion therapy. Short-axis images acquired by cine FIESTA sequence were used to analyze the motion of the different anatomy regions. Used the FGRE ET sequence to detect the patterns of the first-pass perfusion after injection of 0.2 mmol·kg-1 Gd-DTPA at a flow of 3 ml·s-1. 7-12 min later, MDE pulse sequence used to recognize the high signal in the myocardium. Results: At study entry, 38 subjects had the defect in the first-pass perfusion. The signal in the defect was significantly lower than that in the normal regions, which always in the sub-endocardium. 51 subjects had delayed enhancement regions in the myocardium at different degree and different range. The mean intensity of hyper-enhanced regions was 4.36 times higher compared with that of the regions without hyper-enhancement. the difference between the 2 regions had statistical significance. The extent of hyper-enhancement was significantly related to the abnormality of wall motion. The range of delayed enhancement was bigger than that of the first-perfusion defect. Conclusion: Comprehensive evidence of delayed hyper-enhancement, dysfunction of myocardium, and the defect of first-pass perfusion can be used to predict myocardial infarction

    Full Text Available Objective. We evaluated inflammatory cytokines and chemokine in peripheral blood mononuclear cells (PBMCs in patients with either acute coronary syndrome (ACS or stable coronary artery disease (CAD. Methods. We enrolled 20 ACS patients and 50 stable CAD patients without previous history of ACS who underwent cardiac catheterization. Patients with an estimated glomerular filtration rate of ≤30 mL/min/1.73 m2 and C-reactive protein of ≥1.0 mg/dL were excluded. Blood samples were collected from the patients just before catheterization, and PBMCs were isolated from the whole blood. The levels of inflammatory cytokines and chemokine were measured by using real-time quantitative polymerase chain reaction and immunoassays. Results. The expression of tumor necrosis factor alpha (TNF-α, interleukin- (IL- 6, IL-10, IL-23A, IL-27, and IL-37 was significantly higher in the ACS group than in the CAD group (P<0.05. In contrast, the expression of IL-33 was significantly lower in the ACS group than in the CAD group (P<0.05. The ACS patients had higher plasma levels of TNF-α, IL-6, and IL-10 in the ACS group than in the CAD group. Conclusion. Circulating levels of pro-/anti-inflammatory cytokines, including IL-23A, IL-27, IL-33, and IL-37, may be associated with the pathogenesis of atherosclerosis in ACS patients.

    We investigated the relation between overall atheroma burden and clinical events in the Providing Regional Observations to Study Predictors of Events in the Coronary Tree (PROSPECT) study. In PROSPECT, 660 patients (3,229 nonculprit lesions with a plaque burden ≥ 40% and complete intravascular ultrasound data) were divided into tertiles according to baseline percent atheroma volume (PAV: total plaque/vessel volume). Patients were followed for 3.4 years (median); major adverse cardiac events (MACE: death from cardiac causes, cardiac arrest, myocardial infarction, or rehospitalization because of unstable or progressive angina) were adjudicated to either culprit or nonculprit lesions. Compared with patients in low or intermediate PAV tertiles, patients in the high PAV tertile had the greatest prevalence of plaque rupture and radiofrequency thin-cap fibroatheroma (VH-TCFA) and the highest percentage of necrotic core volume; they were also more likely to have high-risk lesion characteristics: ≥ 1 lesion with minimal luminal area ≤ 4 mm(2), plaque burden >70%, and/or VH-TCFA. Three-year cumulative nonculprit lesion-related MACE was greater in the intermediate and high tertiles than in the low tertile (6.3% vs 14.7% vs 15.1%, low vs intermediate vs high tertiles, p = 0.009). On Cox multivariable analysis, insulin-dependent diabetes (hazard ratio [HR] 3.98, p = 0.002), PAV (HR 1.06, p = 0.03), and the presence of ≥1 VH-TCFA (HR 1.80, p = 0.02) were independent predictors of nonculprit MACE. In conclusion, increasing baseline overall atheroma burden was associated with more advanced, complex, and vulnerable intravascular ultrasound lesion morphology and independently predicted nonculprit lesion-related MACE in patients with acute coronary syndromes after successful culprit lesion intervention.

  6. Clinical Significance of Determination of the Serum Levels of NT-proBNP and hs-CRP in Patients with Acute Coronary Syndrome

    To explore the clinical significance the serum levels of N-Terminal proB-Type natriuretic peptide (NT-proBNP) and high-sensitivity C-reactive protein (hs-CRP) in patients with acute coronary syndrome,the serum levels of NT-proBNP and hs-CRP in patients and normal controls were determined by ECi Immunity Analyzer and radioimmunoassay respectively. The results showed that the serum levels of NT-proBNP and hs-CRP in patients with acute coronary syndrome were significantly higher than that of controls (P<0.05). The diagnostic specificity for acute coronary syndrome was 100% by combined detection of NT-proBNP and hs-CRP. The results suggest that the combined detection of serum NT-proBNP and hs-CRP levels are very important to evaluate heart function in patients with acute coronary syndrome. (authors)

The objective of this study was to assess the cost-effectiveness of ticagrelor compared with clopidogrel in ACS patients from the perspective of the Canadian publicly funded health care system.Methods: A two-part model was developed consisting of a 1-year decision tree and a lifetime Markov model. Within the decision tree, patients remained event-free, experienced a nonfatal myocardial infarction, a nonfatal stroke, or death due to vascular or nonvascular related causes based on data from the PLATO trial. The lifetime Markov model followed these patients and allowed for subsequent myocardial infarction, stroke, and death. Patient utility and resource use were derived from the PLATO trial. Transition probabilities and specific Canadian unit costs were derived from published sources. Univariate and probabilistic sensitivity analyses were conducted.Results: In the base case lifetime analysis, treatment with ticagrelor resulted in more years of life per person (0.097, more quality-adjusted life years per person (QALYs, 0.084, and an incremental cost per QALY gained of $9,745 (Canadian$, assuming a generic cost for clopidogrel.

    Full Text Available Abstract Background Shorter time to treatment is associated with lower mortality in acute coronary syndromes (ACS. A previous (1994 survey showed substantial delays for acute myocardial infarction (AMI in Ireland. The present study compared current practice with 1994 and surveyed acute coronary syndromes as a more complete contemporary evaluation of critical cardiac care than assessing AMI alone. Methods Following ethics committee approval, all centres (N = 39 admitting acute cardiac patients to intensive/coronary care unit provided information on 1365 episodes. A cross-sectional survey design was employed. Results Since 1994, median hospital arrival to thrombolysis time was reduced by 41% (76 to 45 minutes. Thrombolysis was delivered more often in the emergency department in 2003 (48% vs 2%. Thrombolysis when delivered in the emergency department was achieved faster than thrombolysis delivered in intensive/coronary care (35 mins v 60 mins; z = 5.62, p Conclusions Substantial improvements in time to thrombolysis have occurred since 1994, probably relating to treatment provision in emergency departments. Patient delay pre-hospital is still the principal impediment to effective treatment of ACS. A recent change of definition of AMI may have precluded an exact comparison between 1994 and 2003 data.

    Conclusions: Acute coronary syndrome is more age dependent in females. The predominance of dyslipidemia, hypertension and obesity as risk factors gives a message for primary care physicians to create awareness for the prevention of Acute Coronary Syndrome. The atypical symptoms should be recognised early which should further prevent the delay in presentation. [Int J Res Med Sci 2014; 2(4.000: 1558-1562

  12. Multidetector computed tomography-guided treatment strategy in patients with non-ST elevation acute coronary syndromes: a pilot study

    Patients with non-ST elevation acute coronary syndrome (ACS) and evidence of myocardial ischaemia are scheduled for coronary angiography (CAG). In most patients CAG remains a single diagnostic procedure only. A prospective study was performed to evaluate whether 16-slice multidetector CT (MDCT) could predict treatment of the patients and to determine how many CAGs could have been prevented by MDCT scanning prior to CAG. Twenty-two patients with ACS were scanned prior to CAG. Based on MDCT data, a fictive treatment was proposed and compared to CAG-based treatment. Excellent accuracy was observed to detect significant stenoses using MDCT (sensitivity 94%, specificity 96%). In 45%, no PCI was performed during CAG, because of the absence of significant coronary artery disease (27%) or severe coronary artery disease, demanding CABG (18%). MDCT predicted correct treatment in 86%. By using MDCT data, 32% of the CAGs could have been prevented. (orig.)

    In the past 3 decades, a better understanding of the pathophysiology of cardiovascular disease has resulted in innovations in the treatment and prevention of its clinical manifestations such as death, myocardial infarction, or stroke. After an acute coronary syndrome there are short- and long-term risks of subsequent cardiovascular events. This leads to opportunities to initiate strategies to reduce complications resulting from myocardial injury (cardiac protection) and to prevent recurrent acute coronary events (vascular protection). The results from clinical trials inform best practice and guidelines for patient management. Despite clear and consistent guidelines, an important number of patients are not receiving these treatments. Moreover, many others do not receive treatment that follows the strategy proven in the clinical trial and this is associated with a significant loss of opportunities to improve outcomes. The Canadian Heart Research Centre has therefore assembled a panel of experts to provide a review of available data and distill it to specific evidence-based recommendations that can be used by specialists and primary care physicians as a platform for secondary prevention. The therapeutic recommendations are conveniently divided into vascular protection (dual antiplatelet therapy, lipid-lowering, and renin angiotensin system inhibition) which should be considered in all patients; cardiac protection (addition of β-blocker therapy) in patients with left ventricular dysfunction including consideration for management of heart failure; and continuing management of risk factors and comorbid conditions on the basis of the specific patient profile. These recommendations are intended as a decision support tool and a quick reference for Canadian physicians. PMID:27342696

  14. Comparison of the TIMI and the GRACE risk scores with the extent of coronary artery disease in patients with non-ST-elevation acute coronary syndrome

    Objective: To compare the accuracy of the Global Registry of Acute Coronary Events risk score and the Thrombolysis In Myocardial Infarction risk score in predicting the extent of coronary artery disease in patients with non-ST segment elevation acute coronary syndrome. Methods: The cross-sectional study comprising 406 consecutive patients was conducted at the National Institute of Cardiovascular Diseases, Karachi, from August 2010 to March 2011. For all patients, the GRACE and TIMI RS's relevant scores on the two indices were calculated on admission using specified variables. The patients underwent coronary angiography to determine the extent of the disease. A significant level was defined as >70% stenosis in any major epicardial artery or >50% stenosis in the left main coronary artery. SPSS 19 was used for statistical analysis. Results: Both the indices showed good predictive value in identifying the extent of the disease. A Thrombolysis In Myocardial Infarction score >4 and Global Registry of Acute Coronary Events score >133 was significantly associated with 3vessel disease and left main disease, while for the former score <4 and latter score <133 was associated with normal or non-obstructive coronary disease (p<0.01). On comparison of the two risk scores, the discriminatory accuracy of the latter was significantly superior to the former in predicting 2vessel, 3vessel and left main diseases (p<0.05). Conclusion: Although both the indices were helpful in predicting the extent of the disease, the Global Registry showed better performance and was more strongly associated with multi-vessel and left main coronary artery disease.

  16. Coagulation factors and recurrence of ischemic and bleeding adverse events in patients with acute coronary syndromes.

    Campo, Gianluca; Pavasini, Rita; Pollina, Alberto; Tebaldi, Matteo; Ferrari, Roberto

    2013-08-01

    In the last years, management and prognosis of patients with acute coronary syndromes (ACS) are significantly improved. Nowadays antithrombotic (antiplatelet plus anticoagulant drugs) therapy represents the main treatment of ACS patients. Anticoagulant drugs are particularly helpful in the acute phase of ACS, whereas in the chronic phase are maintained only in selected cases. Many studies demonstrate that exists a significant variability in the coagulation factor levels between patients affected by ACS. This variation on coagulation factors levels is due to environmental (smoking, inflammation, sex, oral contraceptive, triglycerides, diabetes mellitus) and genetic determinants. Particularly several gene polymorphisms have been selected and clearly associated with significant variations in the coagulation factors values. The heightened levels of tissue factor, factor VII and fibrinogen are related with a "hypercoagulable status" and with a higher occurrence of ischemic complications after ACS and/or PCI. On the contrary, less data are available regarding the relationship between coagulation factors levels (or their gene polymorphisms) and bleeding complications. Recently, new anticoagulant drugs have been developed. They show less side effects and a better tolerability and, probably, their selected use in patients with a "hypercoagulable status" may improve the clinical outcome after ACS. In this review we analyze the current available data and we discuss how this finding may be useful for planning future studies to optimize the treatment of ACS patients. PMID:23827698

    Extracellular vesicles (EVs) are released from various cell types and play an important role in intercellular interactions. In our study, we investigated abundance of individual EVs in patients with acute forms of ischemic heart disease. Previously, we developed an approach for individual analysis of EVs conjugated with magnetic nanoparticles (MNPs), which was applied in the current study for analyzing phenotypic composition of EVs (by staining for markers CD31, CD41a, and CD63). EVs were isolated using fluorescently labeled MNPs containing anti-CD31, CD41a, or CD63 antibodies and analyzed by combining fluorescently labeled anti-CD41a and CD63, CD31 and CD63, or CD41a and CD31 antibodies, respectively. EVs were analyzed in 30 individuals: 17 healthy volunteers and 13 patients with acute coronary syndrome (ACS). Six and seven ACS patients were with acute myocardial infarction and unstable angina, respectively. It was found that patients with ACS and healthy volunteers contained a dominant subset of EVs expressing surface CD41a antigen, suggesting that they originated from platelets. In addition, the total number of EVs isolated using either of the surface markers examined in our study was higher in patients with ACS compared to healthy volunteers. The subgroup of patients with acute myocardial infarction was found to contain significantly higher number of blood EVs compared to the control group. Moreover, increased number of EVs in patients with ACS is mainly due to the increased number of EVs in the subset of EVs bearing CD41a. By analyzing individual EVs, we found that plasma of patients with ACS, particularly upon developing of myocardial infarction, contained dominant platelet-derived EVs fraction, which may reflect activation of platelets in such patients.

    Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

    Introduction It is known that thyroid homeostasis is altered during the acute phase of cardiac arrest. However, it is not clear under what conditions, how and for how long these alterations occur. In the present study we examined thyroid function tests (TFTs) in the acute phase of cardiac arrest caused by acute coronary syndrome (ACS) and at the end of the first 2 months after the event. Method Fifty patients with cardiac arrest induced by ACS and 31 patients with acute myocardial infarction (AMI) who did not require cardioversion or cardiopulmonary resuscitation were enrolled in the study, as were 40 healthy volunteers. The patients were divided into three groups based on duration of cardiac arrest (10 min). Blood samples were collected for thyroid-stimulating hormone (TSH), tri-iodothyronine (T3), free T3, thyroxine (T4), free T4, troponin-I and creatine kinase-MB measurements. The blood samples for TFTs were taken at 72 hours and at 2 months after the acute event in the cardiac arrest and AMI groups, but only once in the control group. Results The T3 and free T3 levels at 72 hours in the cardiac arrest group were significantly lower than in both the AMI and control groups (P 0.05). At the 2-month evaluation, a dramatic improvement was observed in T3 and free T3 levels in the cardiac arrest group (P < 0.0001). In those patients whose cardiac arrest duration was in excess of 10 min, levels of T3, free T3, T4 and TSH were significantly lower than those in patients whose cardiac arrest duration was under 5 min (P < 0.001, P < 0.001, P < 0.005 and P < 0.05, respectively). Conclusion TFTs are significantly altered in cardiac arrest induced by ACS. Changes in TFTs are even more pronounced in patients with longer periods of resuscitation. The changes in the surviving patients were characterized by euthyroid sick syndrome, and this improved by 2 months in those patients who did not progress into a vegetative state. PMID:16137355

  1. Macrophage Myeloperoxidase Regulation by Granulocyte Macrophage Colony-Stimulating Factor in Human Atherosclerosis and Implications in Acute Coronary Syndromes

    2001-01-01

    Inflammation and oxidative stress contribute to the pathogenesis of many human diseases including atherosclerosis. Advanced human atheroma contains high levels of the enzyme myeloperoxidase that produces the pro-oxidant species, hypochlorous acid (HOCl). This study documents increased numbers of myeloperoxidase-expressing macrophages in eroded or ruptured plaques causing acute coronary syndromes. In contrast, macrophages in human fatty streaks contain little or no myeloperoxidase. Granulocyte...

    2014-01-01

    Background. Insulin resistance has been associated with dyslipidemia and cardiovascular disease. Even though homeostasis model assessment of insulin resistance (HOMA-IR) is a well-known insulin resistance predictor, estimation of serum lipoprotein ratios has been recently suggested as a surrogate marker for insulin resistance. Here, we evaluated the relationship between lipoprotein ratios and insulin resistance in normoglycemic nondiabetic south Indians with acute coronary syndrome. Methods. ...

    2015-04-01

    Full Text Available Background: Inflammation has been proposed as a contributor to different stages in the pathogenesis of Coronary Heart Disease (CHD. High sensitive C-Reactive Protein (hs-CRP, an acute-phase plasma protein synthesized by the liver, is the most extensively studied systemic marker of inflammation. Elevated hsCRP concentrations early in Acute Coronary Syndrome (ACS, prior to the tissue necrosis, may be a surrogate marker for cardiovascular co-morbidities. The cardiac marker enzymes Creatine Kinase myocardial bound (CK-MB, Aspartate Aminotransferase (AST and lactate dehydrogenase (LDH have been known to be increased in coronary artery diseases. Objective: The aim of the study was to measure hs-CRP levels and other cardiac marker enzymes in ACS patients and to compare the levels of hs-CRP with other cardiac marker enzymes between ST Elevation Myocardial Infarction (STEMI and Non-ST Elevation Myocardial Infarction (NSTEMI patients. Material and Methods: The study group consisted of 207 consecutive patients admitted to Sri Siddhartha Medical College Hospital within the first 6 hours from the onset of chest pain. Patients were diagnosed as Unstable Angina (UA, (n=84; STEMI (n=63 and NSTEMI (n=60. ACS patients were compared with 211 healthy age and sex matched controls. Hs-CRP, CK-MB, AST and LDH levels were measured by standard methods in both groups at baseline and forcases at 36-48 hours i.e. Peak levels. Results: ACS patients had significantly (p<0.05 higher levels of hs-CRP, CKMB, AST and LDH in comparison to controls at baseline. Hs-CRP, CK-MB, AST and LDH levels were significantly higher in STEMI patients compared to NSTEMI patients (p<0.05 at baseline. There was a significant difference regarding peak hs-CRP levels between the two groups, as STEMI patients had significantly higher peak hs-CRP levels compared to NSTEMI patients (p<0.05. Conclusion: STEMI patients have significantly higher peak hsCRP levels compared to NSTEMI patients. These data

    2006-01-01

    Objective To determine the validity of the GRACE (Global Registry of Acute Coronary Events) prediction model for death six months after discharge in all forms of acute coronary syndrome in an independent dataset of a community based cohort of patients with acute myocardial infarction (AMI). Design Independent validation study based on clinical data collected retrospectively for a clinical trial in a community based population and record linkage to administrative databases. Setting Study conducted among patients from the EFFECT (enhanced feedback for effective cardiac treatment) study from Ontario, Canada. Patients Randomly selected men and women hospitalised for AMI between 1999 and 2001. Main outcome measure Discriminatory capacity and calibration of the GRACE prediction model for death within six months of hospital discharge in the contemporaneous EFFECT AMI study population. Results Post‐discharge crude mortality at six months for the EFFECT study patients with AMI was 7.0%. The discriminatory capacity of the GRACE model was good overall (C statistic 0.80) and for patients with ST segment elevation AMI (STEMI) (0.81) and non‐STEMI (0.78). Observed and predicted deaths corresponded well in each stratum of risk at six months, although the risk was underestimated by up to 30% in the higher range of scores among patients with non‐STEMI. Conclusions In an independent validation the GRACE risk model had good discriminatory capacity for predicting post‐discharge death at six months and was generally well calibrated, suggesting that it is suitable for clinical use in general populations.

Methods: A retrospective analysis was conducted using the Medical Expenditure Panel Survey from 1998 to 2009. Four mutually exclusive cohorts were evaluated: ACS only, ACS with atrial fibrillation (AF, ACS with heart failure (HF, and ACS with both conditions. Direct costs were calculated for all-cause and cardiovascular-related health care resource utilization. Indirect costs were determined from productivity losses from missed days of work. Regression analysis was developed for each outcome controlling for age, US census region, insurance coverage, sex, race, ethnicity, education attainment, family income, and comorbidity burden. A negative binomial regression model was used for health care utilization variables. A Tobit model was utilized for health care costs and productivity loss variables. Results: Total health care costs were greatest for those with ACS and both AF and HF ($38,484±5,191 followed by ACS with HF ($32,871±2,853, ACS with AF ($25,192±2,253, and ACS only ($17,954±563. Compared with the ACS only cohort, the mean all-cause adjusted health care costs associated with ACS with AF, ACS with HF, and ACS with AF and HF were $5,073 (95% confidence interval [CI] 719–9,427, $11,297 (95% CI 5,610–16,985, and $15,761 (95% CI 4,784–26,738 higher, respectively. Average wage losses associated with ACS with and without AF and/or HF amounted to $5,266 (95% CI -7,765, -2,767, when compared with patients

    Background and Objectives We assessed plaque erosion of culprit lesions in patients with acute coronary syndrome in real world practice. Subjects and Methods Culprit lesion plaque rupture or plaque erosion was diagnosed with optical coherence tomography (OCT). Intravascular ultrasound (IVUS) was used to determine arterial remodeling. Positive remodeling was defined as a remodeling index (lesion/reference EEM [external elastic membrane area) >1.05. Results A total of 90 patients who had plaque rupture showing fibrous-cap discontinuity and ruptured cavity were enrolled. 36 patients showed definite OCT-plaque erosion, while 7 patients had probable OCT-plaque erosion. Overall, 26% (11/43) of definite/probable plaque erosion had non-ST elevation myocardial infarction (NSTEMI) while 35% (15/43) had ST elevation myocardial infarction (STEMI). Conversely, 14.5% (13/90) of plaque rupture had NSTEMI while 71% (64/90) had STEMI (p<0.0001). Among plaque erosion, white thrombus was seen in 55.8% (24/43) of patients and red thrombus in 27.9% (12/43) of patients. Compared to plaque erosion, plaque rupture more often showed positive remodeling (p=0.003) with a larger necrotic core area examined by virtual histology (VH)-IVUS, while negative remodeling was prominent in plaque erosion. Overall, 65% 28/43 of plaque erosions were located in the proximal 30 mm of a culprit vessel-similar to plaque ruptures (72%, 65/90, p=0.29). Conclusion Although most of plaque erosions show nearly normal coronary angiogram, modest plaque burden with negative remodeling and an uncommon fibroatheroma might be the nature of plaque erosion. Multimodality intravascular imaging with OCT and VH-IVUS showed fundamentally different pathoanatomic substrates underlying plaque rupture and erosion. PMID:27482258

    2012-01-01

    Background Pulmonary embolism (PE) is often mistaken as acute coronary syndromes (ACS) because of the considerable overlap in their clinical features.We evaluated the factors causing misdiagnosis of PE as ACS and factors that differentiate PE from ACS to improve the diagnosis efficacy of PE.Methods The medical records of 22 consecutive PE patients,between 2001 and 2010,who were initially suspected of ACS were retrieved.ACS was ruled out by coronary artery angiography before a definite diagnosis of PE was given.Twenty-two contemporary cases of ACS matched by age and sex were recruited as controls.Clinical manifestations,electrocardiograms (ECG),and biomarkers of these patients were reviewed retrospectively.The factors causing misdiagnosis of PE as ACS and factors differentiating PE from ACS were evaluated.Results We found two leading causes of misdiagnosis of PE as ACS.One is that PE can resemble ACS in several clinical aspects (symptoms and signs,ECG findings,plasma cardiac troponin I,and D-dimer).The other is the insufficient recognition of PE by clinicians.Risk factors for venous thromboembolism (VTE),especially deep venous thrombosis (DVT),together with signs of PE,such as unexplained dyspnea or hypoxemia,and right ventricular pressure overload on ECGs are valuable in differentiating the two diseases.Conclusions Differentiation between PE and ACS is sometimes challenging.Adequate awareness of the risk factors for VTE and the signs of PE are crucial in the diagnosis of PE.

  10. Influence of Daily Individual Meteorological Parameters on the Incidence of Acute Coronary Syndrome

    2014-11-01

    Full Text Available Background: A nationwide study was conducted to explore the short term association between daily individual meteorological parameters and the incidence of acute coronary syndrome (ACS treated with coronary emergency catheter interventions in the Republic of Slovenia, a south-central European country. Method: We linked meteorological data with daily ACS incidence for the entire population of Slovenia, for the population over 65 years of age and for the population under 65 years of age. Data were collected daily for a period of 4 years from 1 January 2008 to 31 December 2011. In line with existing studies, we used a main effect generalized linear model with a log-link-function and a Poisson distribution of ACS. Results and Conclusions: Three of the studied meteorological factors (daily average temperature, atmospheric pressure and relative humidity all have relevant and significant influences on ACS incidences for the entire population. However, the ACS incidence for the population over 65 is only affected by daily average temperature, while the ACS incidence for the population under 65 is affected by daily average pressure and humidity. In terms of ambient temperature, the overall findings of our study are in line with the findings of the majority of contemporary European studies, which also note a negative correlation. The results regarding atmospheric pressure and humidity are less in line, due to considerable variations in results. Additionally, the number of available European studies on atmospheric pressure and humidity is relatively low. The fourth studied variable—season—does not influence ACS incidence in a statistically significant way.

  11. A variant at chromosome 9p21 is associated with recurrent myocardial infarction and cardiac death after acute coronary syndrome:the GRACE Genetics Study

    2010-01-01

    Background Inverted T waves in precordial leads are often seen in patients with acute pulmonary embolism (APE) and acute coronary syndrome (ACS). The purpose of this study was to analyze the electrocardiogram (ECG) difference between APE and ACS related inverted T waves in precordial leads. Methods The ECG difference among 62 patients with APE and 125 patients with ACS related inverted T waves in precordial leads were compared. Results Compared with ACS, Patients with APE were more frequently associated with incomplete or complete RBBB or slurred S wave in lead V1, the sum of the depth of inverted T waves in leads V1 and V2 not less than in lead V3 and V4 (inverted TV1 + V2 ≥ inverted TV3 + V4), and inverted T waves in leads V1 and Ⅲ. Conclusions Complete or incomplete RBBB or slurred S wave in lead V1, inverted T waves in leads V1 and III, and inverted TV1 + V2 ≥ inverted TV3 + V4 are useful criteria for predicting APE.

    2014-01-01

    Objective Acute coronary syndrome (ACS) is a challenging issue in cardiovascular medicine. Given platelet role in atherothrombosis, we sought to determine whether platelet indices can be used as diagnostic tests for patients who suffered from an acute chest discomfort. Methods We prospectively enrolled 862 patients with an acute chest pain and 184 healthy matched controls. They were divided into four groups: 184 controls, 249 of non-ACS, 421 of unstable angina (UA), and 192 of myocardial infarction (MI) cases. Blood samples were collected at admission to the emergency department for routine hematologic tests. Results The mean platelet volume (MPV), platelet distribution width (PDW), and platelet large cell ratio (P-LCR) were significantly greater in patients with MI compared with those of non-ACS or control subjects. Negative and significant correlations existed between MPV, PDW, and P-LCR values and platelet count (P < 0.001). Receiver operating characteristic (ROC) curves showed that the MPV, PDW, and P-LCR with cut-off values of 9.15 fL, 11.35 fL, and 20.25% and with area under the curves of 0.563, 0.557, and 0.560, respectively, detected MI patients among those who had chest discomfort. The sensitivities and specificities were found to be 72% and 40%, 73% and 37%, and 68% and 44% for MPV, PDW, and P-LCR, respectively. Conclusion An elevated admission MPV, PDW, and P-LCR may be of benefit to detect chest pain resulting in MI from that of non-cardiac one, and also for risk stratification of patients who suffered from an acute chest discomfort.

    2012-01-01

    In the United States alone, more than 400,000 Americans die annually from coronary artery disease and more than 1,000,000 suffer acute coronary events, i.e., myocardial infarction and sudden cardiac death.1 Considering the aging of our population and increasing incidence of diabetes and obesity, the morbidity from coronary artery disease, and its associated costs, will place an increasing, substantial burden on our society.2 Between 2010 and 2030, total direct medical costs spent in the US for cardiovascular diseases are projected to triple from 273 to 818 billion dollars.2 Although effective treatments are available and considerable efforts are ongoing to identify new strategies for the prevention of coronary events, predicting such events in an individual has been challenging.3 In hopes of improving our ability to determine the risk of coronary events, it is prudent to review our knowledge of factors that lead to acute coronary events.

  15. Identification of high-risk acute coronary syndromes by spectral analysis of ear photoplethysmographic waveform variability

    There is a need for robust techniques for early and accurate diagnosis of acute coronary syndromes (ACSs), to avoid inappropriate discharge of patients. This study examined the use of frequency spectrum analysis of heart rate variability (HRV) and photoplethysmogram (PPG) waveform variability for the identification of high-risk ACS patients defined by an elevated cardiac troponin level. The study cohort comprised a convenience sample of adult patients presenting to the emergency department of the Prince of Wales Hospital over a 4 month period complaining of non-traumatic chest pain. Valid electrocardiogram (ECG) and earlobe PPG waveforms together with troponin I test results were obtained from 52 patients at presentation, 4 of which were troponin I positive (Trop 0+). Frequency spectrum analysis was performed on the beat-to-beat HRV and PPG waveform variability (PPGV). The Trop 0+ were found to have significantly higher normalized mid-frequency power (MFnu) in HRV (P = 0.017), PPG amplitude variability (P = 0.009) and the cross-spectrum of HRV and PPGV (P = 0.001), which were attributed to reflex sympathetic response to myocardial ischemia. MFnu of PPG amplitude had the best overall performance in detecting Trop 0+, with ROC area under the curve of 0.93. The results demonstrate the potential use of ear PPG waveform to identify high-risk heart disease patients, and further highlight the utility of frequency spectrum analysis of PPGV in critical care

  16. Association between monocyte Fcγ subclass expression and acute coronary syndrome

    Buchanan Thomas A

    2004-11-01

    Full Text Available Abstract Background Atherosclerosis lesions contain abundant immunoglobulins complexed with oxidized LDL (OxLDL that are endocytosed by macrophages to form foam cells. While recent evidence supports a role for the macrophage scavenger receptor pathway in 75–90% of OxLDL uptake, in vitro evidence suggests another potential uptake pathway could involve autoantibody binding to IgG subclass-specific Fc receptors. Objective and Methods To address this mechanism from an in vivo standpoint, the objective of this study was to utilize flow cytometry to prospectively determine monocyte Fcγ (FcR I, II, and III receptor expression levels in patients with acute coronary syndrome (ACS, n = 48, diabetes mellitus (DM, n = 59, or neither (C, n = 88. Results Increased FcR I expression was found in the ACS versus DM groups [geometric mean, (95% CI = 2.26 (2.07, 2.47 versus 1.83 (1.69, 1.98 (p Conclusions This in vivo data supports a possible second OxLDL-autoantibody macrophage uptake mechanism through an Fc receptor-mediated pathway and a potential relationship between atherosclerotic plaque macrophage FcR levels and ACS.

    2010-01-01

    Background: The use of specific COX-2 inhibitors in cancer prevention has been associated with higher risk of acute coronary syndrome (ACS) and myocardial infarction. The aim of this study was to investigate if the polymorphisms COX2 T8473C (rs5275), and COX2 A-1195G (rs689466), which modify the...... enzyme levels of COX-2, were associated with risk of ACS and if alcohol intake, smoking, and use of NSAID would modify the associations. We also wanted to investigate associations with blood lipid levels. Methods: A case–cohort study including 1031 ACS cases and a sub-cohort of 1703 persons was nested...... within the population-based prospective study Diet, Cancer and Health of 57,053 individuals aged 55-64 at recruitment 1993-1997. Results: Male variant allele carriers of COX-2 T8473C were at lower risk of ACS (IRR=0.75, CI=0.61-0.93, p=0.008) than homozygous wildtype carriers. There were no statistically...

  18. Prediction of adverse outcomes of acute coronary syndrome using intelligent fusion of triage information with HUMINT

    McCullough, Claire L.; Novobilski, Andrew J.; Fesmire, Francis M.

    2006-04-01

    Faculty from the University of Tennessee at Chattanooga and the University of Tennessee College of Medicine, Chattanooga Unit, have used data mining techniques and neural networks to examine a set of fourteen features, data items, and HUMINT assessments for 2,148 emergency room patients with symptoms possibly indicative of Acute Coronary Syndrome. Specifically, the authors have generated Bayesian networks describing linkages and causality in the data, and have compared them with neural networks. The data includes objective information routinely collected during triage and the physician's initial case assessment, a HUMINT appraisal. Both the neural network and the Bayesian network were used to fuse the disparate types of information with the goal of forecasting thirty-day adverse patient outcome. This paper presents details of the methods of data fusion including both the data mining techniques and the neural network. Results are compared using Receiver Operating Characteristic curves describing the outcomes of both methods, both using only objective features and including the subjective physician's assessment. While preliminary, the results of this continuing study are significant both from the perspective of potential use of the intelligent fusion of biomedical informatics to aid the physician in prescribing treatment necessary to prevent serious adverse outcome from ACS and as a model of fusion of objective data with subjective HUMINT assessment. Possible future work includes extension of successfully demonstrated intelligent fusion methods to other medical applications, and use of decision level fusion to combine results from data mining and neural net approaches for even more accurate outcome prediction.

  19. Electroconvulsive therapy for depression following acute coronary syndromes: a concern for the anesthesiologist.

    Pourafkari, Nosratollah; Pourafkari, Leili; Nader, Nader D

    2016-06-01

    The prevalence of depression in patients with cardiovascular disease is higher than general population and especially following an acute coronary syndrome (ACS), a significant number of patients report a wide spectrum of behavioral and mood changes attributable to clinical depression. Treatment of depression following ACS event is particularly challenging since most of the therapeutic modalities are associated with increasing the systemic sympathetic tone from neurogenic or pharmacologic sources. Increased activity of the adrenergic and catecholamine activity may further deter the myocardial oxygen supply and demand therefore treating depression should be carefully evaluated for its risk benefit ratio. Electroconvulsive therapy (ECT) is recommended for patients with severe depression, in whom behavioral and pharmacologic treatments have failed. Patients who refuse to take medications or present with any psychological emergency such as harming self or others, are also candidates for ECT. ECT is also associated with sudden surges of catecholamines and may cause recurrent myocardial ischemia and fatal dysrhythmias in patients convalescing from an ACS event. Herein, we provide an overview and practical guidelines for management of patients presented for ECT following ACS. PMID:27185716

  20. Global perspective on acute coronary syndrome: a burden on the young and poor.

    Vedanthan, Rajesh; Seligman, Benjamin; Fuster, Valentin

    2014-06-01

    Ischemic heart disease (IHD) is the greatest single cause of mortality and loss of disability-adjusted life years worldwide, and a substantial portion of this burden falls on low- and middle-income countries (LMICs). Deaths from IHD and acute coronary syndrome (ACS) occur, on average, at younger ages in LMICs than in high-income countries, often at economically productive ages, and likewise frequently affect the poor within LMICs. Although data about ACS in LMICs are limited, there is a growing literature in this area and the research gaps are being steadily filled. In high-income countries, decades of investigation into the risk factors for ACS and development of behavioral programs, medications, interventional procedures, and guidelines have provided us with the tools to prevent and treat events. Although similar tools can be, and in fact have been, implemented in many LMICs, challenges remain in the development and implementation of cardiovascular health promotion activities across the entire life course, as well as in access to treatment for ACS and IHD. Intersectoral policy initiatives and global coordination are critical elements of ACS and IHD control strategies. Addressing the hurdles and scaling successful health promotion, clinical and policy efforts in LMICs are necessary to adequately address the global burden of ACS and IHD. PMID:24902978

    2016-01-01

    This study aims at investigating medication literacy of discharged patients with acute coronary syndrome (ACS) in China, and the important determinants of medication literacy among them. For this purpose, we conducted a prospective cohort study. Patient's demographic and clinical data were retrieved from hospital charts and medication literacy was measured by instructed interview using the Chinese version of Medication Literacy Questionnaire on Discharged Patient between 7 and 30 days after the patient was discharged from the hospital. The results show that medication literacy for the surveyed patients was insufficient: >20% did not have adequate knowledge on the types of drugs and the frequency that they need to take the drugs, >30% did not know the name of and the dosage of the drugs they are taking, and >70% did not have adequate knowledge on the effects and side effects of the drugs they are taking. Our research indicated that medication literacy scores decreased with age but increased with education. The number of medicines the discharged patient took with them and days between discharge and interview were not associated with medication literacy levels. PMID:27428990

  2. Targeting thrombin long-term after an acute coronary syndrome: Opportunities and challenges.

    De Caterina, Raffaele; Goto, Shinya

    2016-06-01

    Patients after an acute coronary syndrome (ACS) are at increased risk of recurrent thrombotic events, justifying the search for additional antithrombotic treatments. The pathophysiology of ACS involves arterial thrombus formation, in turn occurring because of a combination of platelet activation and fibrin formation, with thrombin playing a key role in both. Antiplatelet therapy, targeting the thromboxane pathway and the ADP P2Y12 receptor has been widely accepted for secondary prevention after an ACS. Now, data from recent clinical trials in such patients also encourage the pursuit of inhibiting thrombin formation or thrombin-mediated platelet activation in addition to antiplatelet therapy. This "triple pathway inhibition", including inhibition of thrombin activity or thrombin receptor(s), is currently an option in pure ACS, but already a must in the setting of ACS accompanied by atrial fibrillation (AF), where anticoagulants have been shown to be much more effective than antiplatelet agents in preventing stroke. We here discuss the challenges of managing combined thrombin activity or receptor inhibition and antiplatelet therapy in all such patients. Translating this into practice still requires further studies and patient tailoring to fully exploit its potential. PMID:26994821

    Previously conducted studies revealed that smoking enhanced the efficacy of clopidogrel by increasing formation of the active metabolite (AM) from the prodrug through induction of the cytochrome CYP1A2. The expression of cytochrome enzymes depends on genotype and no data exists in literature conducted in Turkish patients comparing the clopidogrel responsiveness between active smokers and non-active smokers treated with clopidogrel. In this study, our aim was to investigate the clopidogrel responsiveness in clopidogrel-treated Turkish acute coronary syndrome (ACS) patients according to their smoking status. We retrospectively enrolled 258 patients who were hospitalized due to ACS. Clinical variables of the patients, especially smoking status were recorded. Clopidogrel resistance was evaluated by using adenosine diphosphate (ADP) induced platelet aggregometry. Clopidogrel resistance was detected as a change in maximal aggregation ≤20% from baseline. A total of 139 patients were active smokers while 12 were former smokers. 107 patients did not have a history of smoking. Ten of the smokers were hyporesponsive to clopidogrel, whereas 36 of non-smokers were hyporesponsive to clopidogrel (p 612.5 predicted the clopidogrel resistance with a sensitivity of 60% (OR: 100.65, %95 CI = 19.996-506.615 p aspirin than in non-smokers receiving the same drug regimen. This finding indicates that smoking was related to an enhanced clopidogrel responsiveness in Turkish patients hospitalized due to ACS, suggesting that "smoker's paradox" probably exists in Turkish ACS patients.

    2009-04-01

    Full Text Available Abstract Background The prevalence of depression in patients with acute coronary syndrome, i.e. myocardial infarction and unstable angina, is higher than in the general population. The prevalence of anxiety is higher as well. Both depression and anxiety are associated with poor cardiac outcomes and higher mortality. Comorbid depression in patients with acute coronary syndrome often goes undiagnosed, and it is therefore a challenging task to prevent this risk factor. The study of DEpression in Coronary ARtery Disease (DECARD is designed to examine if it is possible to prevent depression in patients with acute coronary syndrome. Methods Two hundred forty non-depressed patients with acute coronary syndrome are randomized to treatment with either escitalopram or placebo for 1 year. Psychiatric and cardiac assessment of patients is performed to evaluate the possibility of preventing depression. Diagnosis of depression and Hamilton Depression Scale are the primary outcome measures. Discussion This is the first study of prevention of depression in patients after acute coronary syndrome with a selective serotonin reuptake inhibitor.

    Objectives To determine the validity and applicability of the global registry of acute coronary events (GRACE) pre-diction model for in-hospital mortality in all forms of acute coronary syndrome (ACS) in a sub population of Chongqing. Methods Data of 669 ACS patients were collected retrospectively from Jan 2005 to Apr 2008 and were re-corded on a standardized case report form. For each patient the GRACE risk score (GRACE RS) was calculated (using the GRACE calculator available from the grace website) using specific variables collected at admission. Patients with missing data and those transferred from other hospitals were excluded. Receiver operating characteristic (ROC) curves were plotted for the GRACE risk score. Results Among 576 ACS patients, 98 (17.01%), 36 (6. 25 %), and 442 (76. 74 %) presented with ST-elevation myocardial infarction (MI), non-ST elevation MI and unstable angina, re-spectively. The GRACE risk score could not be determined in 91 (9. 3 %) patients due to missing data or for patients who were transferred from other hospitals and were excluded from the analysis. The median GRACE risk score was 133 (interquartile range: 92 - 174) and, the in-hospital rates of death and death/(re-) MI were 6. 1% and 7.6 %, respec-tively. The GRACE risk score demonstrated excellent discrimination (c-statistic = 0. 86, 95 % CI 0. 79 - 0. 91, P < 0. 001) for in-hospital death/ (re) -MI. Conclusions The GRACE RS study had a good predictive accuracy for death or MI across the wide range of ACS in this population. It may be a useful risk stratification tool that helps identify high-risk patients who will benefit most from myocardial revascularization and low risk patients who may be spared from un-dergoing more aggressive interventional treatment.

  7. The value and distribution of high-density lipoprotein subclass in patients with acute coronary syndrome.

    Li Tian

    Full Text Available BACKGROUND: High-density lipoprotein (HDL enhances cholesterol efflux from the arterial wall and exhibits potent anti-inflammatory and anti-atherosclerosis (AS properties. Whether raised HDL levels will clinically benefit patients with acute coronary syndrome (ACS and the value at which these effects will be apparent, however, is debatable. This study examined the HDL subclass distribution profile in patients with ACS. METHODS: Plasma HDL subclasses were measured in 158 patients with established ACS and quantified by two-dimensional gel electrophoresis and immunoblotting. ACS diagnosis was based on symptoms of cardiac ischemia, electrocardiogram (ECG abnormalities, speciality cardiac enzyme change along with presence of coronary heart disease (CHD on coronary angiography. RESULTS: The small-sized preβ1-HDL, HDL3b, and HDL3a levels were significantly higher, and the large-sized HDL2a and HDL2b levels were significantly lower in patients with ACS than in those with stable angina pectoris (SAP and in normal control subjects. Meanwhile, with an elevation in the low-density lipoprotein cholesterol (LDL-C, fasting plasma glucose (FPG, body mass index (BMI, and blood pressure (BP, and the reduction in the high density lipoprotein cholesterol (HDL-C levels, the HDL2b contents significantly decreased and the preβ1-HDL contents significantly increased in patients with ACS. The correlation analysis revealed that the apolipoprotein (apoA-I levels were positively and significantly with all HDL subclasses contents; plasma total cholesterol (TC and fasting plasma glucose (FPG levels were inversely associated with HDL2a, and HDL2b. Moreover, the FPG levels were positively related to HDL3c, HDL3b, and HDL3a in ACS patients. CONCLUSION: The HDL subclass distribution profile remodeling was noted in the patients with ACS. Plasma lipoprotein and FPG levels, BP, and BMI play an important role in the HDL subclass metabolism disorder for patients with ACS. The HDL

  8. Cross-reacting antibacterial auto-antibodies are produced within coronary atherosclerotic plaques of acute coronary syndrome patients.

    Filippo Canducci

    Full Text Available Coronary atherosclerosis, the main condition predisposing to acute myocardial infarction, has an inflammatory component caused by stimuli that are yet unknown. We molecularly investigated the nature of the immune response within human coronary lesion in four coronary plaques obtained by endoluminal atherectomy from four patients. We constructed phage-display libraries containing the IgG1/kappa antibody fragments produced by B-lymphocytes present in each plaque. By immunoaffinity, we selected from these libraries a monoclonal antibody, arbitrarily named Fab7816, able to react both with coronary and carotid atherosclerotic tissue samples. We also demonstrated by confocal microscopy that this monoclonal antibody recognized human transgelin type 1, a cytoskeleton protein involved in atherogenesis, and that it co-localized with fibrocyte-like cells transgelin+, CD68+, CD45+ in human sections of coronary and carotid plaques. In vitro fibrocytes obtained by differentiating CD14+ cells isolated from peripheral blood mononuclear cells also interacted with Fab7816, thus supporting the hypothesis of a specific recognition of fibrocytes into the atherosclerotic lesions. Interestingly, the same antibody, cross-reacted with the outer membrane proteins of Proteus mirabilis and Klebsiella pneumoniae (and possibly with homologous proteins of other enterobacteriaceae present in the microbiota. From all the other three libraries, we were able to clone, by immunoaffinity selection, human monoclonal antibodies cross-reacting with bacterial outer membrane proteins and with transgelin. These findings demonstrated that in human atherosclerotic plaques a local cross-reactive immune response takes place.

    2016-01-01

    Background Frail elderly people are at risk of developing adverse health outcomes such as disability, hospitalization, and mortality. In recent years, the literature has drawn attention to the role of frailty syndrome (FS) in acute coronary syndrome (ACS). There are few studies regarding the relationship between two multidimensional variables such as FS and quality of life (QoL). Objective The aim of the study was to investigate the relationship between FS and early QoL of elderly patients with ACS (≥65 years old). Methods The study was conducted among 91 patients aged 65 years and over with ACS. The MacNew questionnaire was used to evaluate QoL and the Tilburg frailty indicator to evaluate frailty. Results FS was present in 82.4% of patients. The average Tilburg frailty indicator score was 7.43±2.57. A negative correlation between the global values of FS and QoL was shown (r=−0.549, P<0.05). The vulnerability factors that negatively affected early QoL were: FS, marital status, conservative therapy, and hypertension. In multivariate analysis, FS was found to be the independent predictor of worse QoL (β ± standard error −0.277±0.122, P=0.026). Conclusion The presence of FS has a negative impact on early QoL in patients with ACS. The study suggests that in elderly patients with ACS, there is a need to identify frailty in order to implement additional therapeutic and nursing strategies in ACS. PMID:27217737

    2016-01-01

    The All New Zealand Acute Coronary Syndrome Quality Improvement programme (ANZACS-QI) uses a web-based system to create a clinical registry of patients with acute coronary syndrome (ACS) and other cardiac problems admitted to hospitals across New Zealand. This detailed clinical registry is complemented by parallel analyses of, and individual linkage to, New Zealand's multiple routine health information datasets. The programme is primarily designed to support secondary care clinicians to implement evidence based guidelines and to meet national performance targets for New Zealand cardiac patients. ANZACS-QI simultaneously generates a large-scale research database and provides an electronic data infrastructure for clinical registry studies. ANZACS-QI has been successfully implemented in all the 41 public hospitals across New Zealand where acute cardiac patients are admitted. By June 2015 25,273 patients with suspected ACS and 30,696 referred for coronary angiography were registered in ANZACS-QI. In this report we describe the development and national implementation of ANZACS-QI, its governance, the data collection processes and the current ANZACS-QI cohorts and available outputs.

    2013-01-01

    Background: Acute Coronary Syndrome (ACS) is increasing in Yemen in recent years and there are no data available on its short and long-term outcome. We evaluated the clinical pictures, management, in-hospital, and long-term outcomes of the ACS patients in Yemen. Design and Setting: A 9-month prospective, multi-center study conducted in 26 hospitals from 9 governorates. The study included 30-day and 1-year mortality follow-up. Patients and Methods: One thousand seven hundred and sixty one patients with ACS were collected prospectively during the 9-month period. Patients with ST-elevation myocardial infarction (STEMI) and non-ST-elevation acute coronary syndrome (NSTEACS), including non-ST-elevation myocardial infarction and unstable angina were included. Conclusions: ACS patients in Yemen present at a relatively young age with high prevalence of Smoking, khat chewing and hypertension. STEMI patients present late, and their acute management is poor. In-hospital evidence-based medication rates are high, but coronary revascularization procedures were very low. In-hospital mortality was high and long-term mortality rates increased two folds compared with the in-hospital mortality. PMID:24695681

  13. Serum Adiponectin and Cardiometabolic Risk in Patients with Acute Coronary Syndromes

    The adipose tissue is considered not only a storable energy source, but mainly an endocrine organ that secretes several cytokines. Adiponectin, a novel protein similar to collagen, has been found to be an adipocyte-specific cytokine and a promising cardiovascular risk marker. To evaluate the association between serum adiponectin levels and the risk for cardiovascular events in patients with acute coronary syndromes (ACS), as well as the correlations between adiponectin and metabolic, inflammatory, and myocardial biomarkers. We recruited 114 patients with ACS and a mean 1.13-year follow-up to measure clinical outcomes. Clinical characteristics and biomarkers were compared according to adiponectin quartiles. Cox proportional hazard regression models with Firth's penalization were applied to assess the independent association between adiponectin and the subsequent risk for both primary (composite of cardiovascular death/non-fatal acute myocardial infarction (AMI)/non-fatal stroke) and co-primary outcomes (composite of cardiovascular death/non-fatal AMI/non-fatal stroke/ rehospitalization requiring revascularization). There were significant direct correlations between adiponectin and age, HDL-cholesterol, and B-type natriuretic peptide (BNP), and significant inverse correlations between adiponectin and waist circumference, body weight, body mass index, Homeostasis Model Assessment (HOMA) index, triglycerides, and insulin. Adiponectin was associated with higher risk for primary and co-primary outcomes (adjusted HR 1.08 and 1.07/increment of 1000; p = 0.01 and p = 0.02, respectively). In ACS patients, serum adiponectin was an independent predictor of cardiovascular events. In addition to the anthropometric and metabolic correlations, there was a significant direct correlation between adiponectin and BNP

    Full Text Available Background: According to some international studies, patients with acute coronary syndrome (ACS and increased left atrial volume index (LAVI have worse long-term prognosis. However, national Brazilian studies confirming this prediction are still lacking. Objective: To evaluate LAVI as a predictor of major cardiovascular events (MCE in patients with ACS during a 365-day follow-up. Methods: Prospective cohort of 171 patients diagnosed with ACS whose LAVI was calculated within 48 hours after hospital admission. According to LAVI, two groups were categorized: normal LAVI (≤ 32 mL/m2 and increased LAVI (> 32 mL/m2. Both groups were compared regarding clinical and echocardiographic characteristics, in- and out-of-hospital outcomes, and occurrence of ECM in up to 365 days. Results: Increased LAVI was observed in 78 patients (45%, and was associated with older age, higher body mass index, hypertension, history of myocardial infarction and previous angioplasty, and lower creatinine clearance and ejection fraction. During hospitalization, acute pulmonary edema was more frequent in patients with increased LAVI (14.1% vs. 4.3%, p = 0.024. After discharge, the occurrence of combined outcome for MCE was higher (p = 0.001 in the group with increased LAVI (26% as compared to the normal LAVI group (7% [RR (95% CI = 3.46 (1.54-7.73 vs. 0.80 (0.69-0.92]. After Cox regression, increased LAVI increased the probability of MCE (HR = 3.08, 95% CI = 1.28-7.40, p = 0.012. Conclusion: Increased LAVI is an important predictor of MCE in a one-year follow-up.

    The protocol of our study includes men with acute myocardial infarction, stable angina pectoris of II and III functional classes and unstable angina pectoris. Patients with arterial hypertension, disorders in carbohydrate metabolism were excluded from the study. Blood samples taken under standardized conditions, were stabilized with citrate sodium 3,8% (1:9). Erythrocytes and platelets aggregation activity under glucose influence (in vitro) was studied by means of computer aided microphotometer -- a visual analyzer. Erythrocyte and platelets were united in special subsystem of whole blood. Temporal and functional characteristics of their aggregation were analyzed by creation of phase patterns fragments. The received data testify to interrelation of erythrocytes and platelets processes of aggregation under conditions of increasing of glucose concentration of the incubatory environment, which temporal and functional characteristics may be used for diagnostics and the prognosis of destabilization coronary blood flow at an acute coronary syndrome.

    Background Long-term use of antiplatelet agents,statins,beta-blockers and angiotensin-converting enzyme inhibitors are proven therapies for secondary prevention in acute coronary syndrome.However,little is known of physicians' opinion about their use in China.Methods In 2010,standard questionnaires were posted to chief cardiologists in 1397 geographically diverse and representative sample of tertiary and secondary hospitals in China,collecting information about their opinions on the recommended treatments for acute coronary syndrome.Results A total of 1009 (72%) cardiologists responded with a valid questionnaire.Of them,77% reported routine use of all the four main secondary preventive treatments,with little difference between secondary and tertiary hospitals (75% vs.79%,P=0.16).Of the cardiologists reporting routine or selective use of aspirin,beta-blockers,statins and angiotensin-converting enzyme inhibitors,94%,85%,73% and 86% would recommend indefinite use respectively.For all the 4 treatments combined,only 63.5% reported indefinite use at the same time,with no significant difference between secondary and tertiary hospitals (62% vs.65%,P=0.17),nor between hospitals with or without fast track for primary percutaneous coronary intervention (66% vs.61%,P=0.50).Conclusions Although Chinese cardiologists seem well informed about the value of main secondary preventive treatments for acute coronary syndrome,there is still gap in their understanding of the need for combined and prolonged use of these treatments.

  1. Non-obstructive low attenuation coronary plaque predicts three-year acute coronary syndrome events in patients with hypertension. Multidetector computed tomographic study

    Arterial hypertension is an established risk factor for acute coronary syndrome (ACS). Multidetector computed tomography (MDCT) is an accurate and less invasive technique for assessment of the degree of coronary artery luminal narrowing and characterization of coronary atherosclerosis. We therefore aimed to investigate the predictive power of MDCT for future ACS events and compared with traditional parameters in patients with hypertension. One hundred and thirty-four patients (93 men, mean age 70±11 years) with hypertension underwent MDCT for evaluation of coronary artery disease. MDCT analysis focused on the presence of plaques, the degree of stenosis, and the plaque characteristics. Traditional parameters included Framingham risk score, carotid intima-media thickness, and left ventricular mass index. During a mean follow-up of 39±10 months, ACS events occurred in 10 patients, including myocardial infarction (n=3) and unstable angina (n=7). Multivariate analysis identified total number of low attenuation plaques as an independent predictor of ACS events (p<0.001). We demonstrated that non-obstructive low attenuation coronary plaques on MDCT predicted more accurately future ACS events in patients with hypertension than traditional parameters. (author)

    Objectives Percutaneous coronary intervention (PCI) for acute coronary syndromes frequently fails to restore myocardial perfusion despite establishing epicardial vessel patency. Endothelin-1 (ET-1) is a potent vasoconstrictor, and its expression is increased in atherosclerosis and after PCI. In this study, we aim to define the role of endothelin in regulating coronary microvascular blood flow and myocardial perfusion following PCI in patients with non-ST elevation acute coronary syndromes (NSTACS), by assessing whether adjunctive therapy with a selective endothelin A (ETA) receptor antagonist acutely improves postprocedural coronary microvascular blood flow. Methods In a randomised, double-blinded, placebo-controlled trial, 23 NSTACS patients were enrolled to receive an intracoronary infusion of placebo (n=11) or BQ-123 (n=12) immediately before PCI. Post-PCI coronary microvascular blood flow and myocardial perfusion were assessed by measuring Doppler-derived average peak velocity (APV), and cardiac biomarker levels were quantified. Results Compared with the placebo group, APV was significantly higher in the drug group immediately after PCI (30 (20, 37) vs 19 (9, 26) cm/s; p=0.03). Hyperaemic APV, measured post-adenosine administration, was higher in the BQ-123 group, but the difference did not achieve statistical significance (56 (48, 72) vs 46 (34, 64) cm/s; p=0.090). Maximum coronary flow reserve postprocedure was not different between the two groups (2.1 (1.6, 2.3) vs 2.5 (1.8, 3.0)). Per cent change in creatine kinase isoenzyme MB from the time of PCI to 8 and 16 hours post-PCI was significantly lower in the drug group compared with the placebo group (−17 (−26, −10) vs 26 (−15, 134); p=0.02 and −17 (−38, 14) vs 107 (2, 446); p=0.007, respectively). Conclusions Endothelin is a mediator of microvascular dysfunction during PCI in NSTACS, and adjunctive selective ETA antagonist may augment myocardial perfusion during PCI. Trial registration number

  3. Rest/stress myocardial perfusion imaging: A means to prevent missed acute ischemic coronary syndrome diagnoses

    Aim: The sensitivity and specificity of rest/stress (R/S) myocardial perfusion imaging (MPI) in detecting an acute ischemic coronary syndrome (AICS) was determined in 100 consecutive patients (pts) admitted to the Chest Pain Clinic-Observation Unit (CPC-OU) with chest pain (CP) of suspected cardiac etiology and a negative (neg) or non diagnostic (dx) EKG. There were 57 females and 43 males, 30-83 years of age. 50 studies were performed from 1/15/98 to 4/2/98; 50 from 11/19/99 to 1/10/00. Material and Methods: An AICS was deemed present if a reversible perfusion defect was demonstrated scintigraphically; a ?50% luminal narrow angiographically. No AICS if the pt had a normal R/S MPI, a fixed defect with normal wall motion and thickening, a neg cardiac catheterization, or was free of cardiac symptoms and had no history of a vascular event for 2-3 years post CPC-OU admission. 13 pts with a positive MPI had a cardiac catheterization, none with a neg MPI. SPECT rest MPI's were performed 30-90 minutes (mins) post 10.0 mCi of technetium 99m Sestamibi. SPECT stress MPI's were performed following a 6-8 hour acute myocardial infarction enzyme (CP-MB/Troponin 1) rule out and 30-90 mins post 30.0 mCi of technetium 99m Sestamibi. Results: 29 pts were lost to follow-up. There were 12 true positive, 5 false positive, 54 true negative and 0 false negative studies. The sensitivity, specificity, positive and negative predictive value of a R/S MPI in detecting an AICS is 100%, 91%, 70% and 100%, respectively. An AICS was detected in 12% of pts admitted to the CPC-OU; a finding that correlates with its reported incidence of 2-12%. 6 were managed medically, 3 required emergent bypass surgery, 3 were stented. Conclusion: R/S MPI should be included in the CPC-OU dx work-up of pts with CP of suspected cardiac etiology to prevent missed AICS diagnoses. Patient care will be optimized and health care and medical malpractice awards for failure to diagnosis an acute myocardial infarction

    Acute kidney injury (AKI) is associated with adverse short-and long-term outcomes. The aim of this study was to evaluate the incidence of AKI and the short-term mortality in patients admitted with acute coronary syndrome (ACS) to a single coronary care unit (CCU) in Tripoli, Libya. We retrospectively studied the medical records of ACS patients admitted to the CCU of a referral cardiology center, during the period from January 1, 2014, to December 31, 2014. AKI was defined according to the AKI network criteria. The incidence of AKI and short-term CCU mortality was compared between different types of ACS. Data of patients with and without AKI were compared using Student's t-test and Chi-squared statistic considering P <0.05 statistically significant. Eighty-four patients with ACS were included in the study; their mean age was 57.6 ± 14.4 years [standard deviation (SD)], 75% were males and their mean stay in the CCU was 4.3 ± 3 days (SD). Of them, 71.4% had ST-elevated myocardial infarction (STEMI), 22.6% had non-STEMI, and 6% had unstable angina. About 41.7% had AKI (19% had AKI Stage 1, 17.9% had AKI Stage 2, and 4.8% had AKI Stage 3). The total CCU mortality was 15.5%; mortality among AKI patients in the CCU was 25.7% compared with 6.12% in the non-AKI patients (P = 0.014). The mortality worsened with increasing severity of AKI. Patients with AKI were older (61.6 ± 15 years) than the non-AKI group (54.7 ± 13 years, P = 0.031), their mean blood pressure at admission was lower, their CCU stay was longer, and they more frequently had coexisting acute decompensated heart failure. In this study of ACS patients, the incidence of AKI was high, the CCU mortality among the AKI patients was 25.7% compared with 6.12% in the non-AKI patients, and the mortality worsened with increasing severity of AKI.

  5. Evaluation of plaque texture by means of multislice computed tomography in patients with acute coronary syndrome and stable angina

    In the present study, multislice spiral computed tomography (MSCT), which allows non-invasive assessment of coronary artery plaque, was used to compare the CT density of plaque between patients with acute coronary syndrome (ACS) and those with stable angina (SA). MSCT was performed in 20 patients with ACS (17 with acute myocardial infarction, 3 with unstable angina) and 22 patients with SA. The presence of the plaque was defined on the basis of multi-planar reformation and axial images. At least 4 regions of interest were then placed within the plaque and the minimum CT density was measured and expressed as Hounsfield units (HU). The number of plaques did not differ between the 2 groups, but the minimum CT density was significantly lower in patients with ACS (25±15 HU) than in those with SA (71±16 HU, range 46-101 HU, p<0.001). Similarly, the minimum plaque density was significantly lower in the culprit coronary segment (26±16 HU) than in the non-culprit segment (48±17 HU) in 15 ACS patients with multiple plaques. MSCT can potentially differentiate vulnerable from stable plaque in patients with coronary artery disease, although long-term, prospective analysis is needed to establish the conclusion. (author)

    Full Text Available Abstract Background Heart failure (HF is a serious complication of acute coronary syndromes (ACS, and is associated with high in-hospital mortality and poor long-term survival. The aims of this study were to describe the clinical characteristics, management and in-hospital outcomes of coronary syndrome (ACS patients with HF in the United Arab Emirates. Findings The study was selected from the Gulf Registry of Acute Coronary Events (Gulf RACE, a prospective multi-national, multicenter registry of patients hospitalized with ACS in six Middle East countries. The present analysis was focused on participants admitted to various hospitals in the UAE with a diagnosis of ACS in 2007 and were analyzed in terms of HF (Killip class II/III and IV on admission. Of 1691 patients (mean age: 52.6 ± 11.7 years; 210 Females, 1481 Males with ACS, 356 (21% had an admission diagnosis of HF (Killip class II/III and IV. HF patients were less frequently males (19.2% vs. 34.3%; P  0.001. HF was more frequently associated with hypertension (64.3% vs. 43.9%; P  Conclusions HF is observed in about 1 in 5 patients with ACS in the UAE and is associated with a significant increase in in-hospital mortality and other adverse outcomes.

  7. Drug-eluting stents for acute coronary syndrome: a meta-analysis of randomized controlled trials.

    Lishan Wang

    Full Text Available Drug-eluting stents (DES are increasingly used for treatment of acute coronary syndrome (ACS. However, clinical efficacy and safety of various types of DES is not well established in these subjects. We therefore evaluated clinical utility of second-generation and first-generation DES in patients with ACS by conducting a meta-analysis.A search of Medline, Embase, the Cochrane databases, and Web of Science was made. Randomized controlled trials (RCTs which compared second-generation DES (everolimus-eluting stents [EES] or zotarolimus-eluting stents [ZES] versus first-generation DES (sirolimus-eluting stents [SES] or paclitaxe-eluting stents [PES] in patients with ACS and provided data on clinical efficacy or safety endpoints were included. Pooled estimates were calculated using random-effects model.A total of 2,757 participants with ACS in 6 RCTs were included. Compared with first-generation one, second-generation DES trended to be associated with the decreased incidence of definite or probable stent thrombosis in ACS patients (risk ratio [RR]  = 0.60, 95% confidence intervals [CI] 0.33 to 1.07, p = 0.09. However, the rate of target lesion revascularization (TLR significantly increased in second-generation DES (RR = 2.08, 95%CI 1.25 to 3.47, p = 0.005. There were no significant differences in the incidence of major adverse cardiac events (MACEs, all-cause death, cardiac death, and recurrent myocardial infarction between the two arms (all p>0.10. The second-generation EES showed a tendency towards lower risk of MACEs (p = 0.06 and a beneficial effect on reducing stent thrombosis episodes (p = 0.009, while the second-generation ZES presented an increased occurrence of MACEs (p = 0.02 and TLR (p = 0.003.Second-generation DES, especially EES, appeared to present a lower risk of stent thrombosis, whereas second-generation ZES might increase the need for repeat revascularization in ACS patients.

  8. Prognostic Usefulness of Low Ischemic Risk SPECT in non-ST Segment Elevation Acute Coronary Syndromes

    Background: Myocardial perfusion imaging tests are used for the clinical assessment of patients hospitalized with non-ST segment elevation acute coronary syndromes (NSTACS) who have favorable in-hospital outcomes with medical therapy. However, the prognostic relevance of a .low ischemic risk. (LR) single photon emission computed tomography (SPECT) in patients with NSTACS managed with a conservative approach is uncertain, as most of the information derives from patients with chronic coronary artery disease. Objectives: 1) To analyze the outcomes of patients with NSTACS and LR SPECT at discharge, 2) to compare the results of a normal SPECT with transient perfusion defects (TPDs), permanent perfusion defects (PPDs) or combined defects (CDs), and 3) to determine the additional value of SPECT to classic risk variables. Material and Methods: Patients admitted to the CCU with a NSTACS were included. Follow-up was continued during 12 months. Definitions: Clinical risk based on TIMI risk score. LR SPECT (under exercise or pharmacological stress): TPDs ≤ 3/17 segments, PPDs ≤ 3/17 segments, CPDs: TPDs + PPDs and normal: absence of defects. Clinical events (CEs): death/infarction or rehospitalization due to angina. Results: A total of 137 patients were included (median age 59 years, 60% were men). A low TIMI risk score was present in 54% of patients and 46% presented a moderate risk. CE: 5.8%. The incidence of clinical events related to perfusion defects was as follows: normal: 2.1%, TPD: 4.5%, PPD: 5.9% and CPD: 25% (p<0.02). At multivariate analysis, which included age, previous myocardial infarction, TIMI risk score and TPD, only CPD was identified as an independent variable for CEs: OR 7.8 (95% CI 1.2-49); p=0.02. Positive predictive value, negative predicted value, positive likelihood ratio and negative likelihood ratio were 25%, 96%, 5.3 and 0.7, respectively. Conclusions: A LR SPECT is useful for the prognostic assessment of patients with low or moderate risk

    We hypothesized that matrix metalloproteinase (MMP)-2, -9, and tissue inhibitor metalloproteinase-1, -2 (TIMP-1, -2) would be abnormal in diabetes and in acute coronary syndromes (ACS). We measured MMP-2, -9, and TIMP-1, -2 plasma levels in healthy subjects (controls), in type 2 diabetic patients, in nondiabetic patients with ACS (ACS) and in diabetic patients with ACS (DACS). We enrolled 165 controls, 181 diabetic patients, 78 ACS, and 46 DACS. We measured also BMI (body mass index), HbA(1c) (glycated hemoglobin) FPG (fasting plasma glucosa), FPI (fasting plasma insulin), HOMA index (homeostasis model assessment index), SBP (systolic blood pressure), DBP (diastolic blood pressure), TC (total cholesterol), LDL-C (low density lipoprotein cholesterol), HDL-C (high-density lipoprotein cholesterol), Tg (triglycerides), Lp(a) (lipoprotein(a)) PAI-1 (plasminogen activator inhibitor-1), Hct (homocysteine), Fg (fibrinogen), and hs-CRP (high-sensitivity C-reactive protein). A significant increase of BMI was observed in the diabetic group, in ACS and DACS patients compared to controls. A significant increase of SBP and DBP resulted in the diabetic and DACS groups, while only SBP improvement was present in ACS patients with respect to controls. A decrease in SBP and DBP was observed in the ACS group, while SBP variation was present in DACS patients compared to diabetics, and DBP increase was obtained in the DACS group with respect to ACS patients. TC, LDL-C, Tg, and Lp(a) increase was present in diabetics, while TC, Tg, and Lp(a) improvement was present in ACS and DACS patients with a significant decrease of HDL-C levels in diabetic, ACS, and DACS groups compared to controls. A decrease in LDL-C was obtained in ACS and DACS groups, while HDL-C increase was observed in these patients with respect to diabetics. Tg levels were higher in the DACS group compared to diabetics and ACS patients, respectively. Increases in PAI-1, Hct, Fg, and hs-CRP were present in diabetic and DACS

    The aim of this study was to evaluate the relationship between weather conditions and daily emergency ambulance calls for acute coronary syndromes (ACS). The study included data on 3631 patients who called the ambulance for chest pain and were admitted to the department of cardiology as patients with ACS. We investigated the effect of daily air temperature (T), barometric pressure (BP), relative humidity, and wind speed (WS) to detect the risk areas for low and high daily volume (DV) of emergency calls. We used the classification and regression tree method as well as cluster analysis. The clusters were created by applying the k-means cluster algorithm using the standardized daily weather variables. The analysis was performed separately during cold (October-April) and warm (May-September) seasons. During the cold period, the greatest DV was observed on days of low T during the 3-day sequence, on cold and windy days, and on days of low BP and high WS during the 3-day sequence; low DV was associated with high BP and decreased WS on the previous day. During June-September, a lower DV was associated with low BP, windless days, and high BP and low WS during the 3-day sequence. During the warm period, the greatest DV was associated with increased BP and changing WS during the 3-day sequence. These results suggest that daily T, BP, and WS on the day of the ambulance call and on the two previous days may be prognostic variables for the risk of ACS. PMID:25344902

    Objective To determine if multi-detector CT (MDCT) characterization of plaque is correlated with the classification of acute coronary syndrome (ACS). Methods Altogether 1900 patients were examined by MDCT from December 2007 to May 2009,of whom 95 patients fulfilled the criteria of ACS. Those patients were divided into the discrete plaque group (n=61) and diffuse plaque group (n=34) based on the findings in MDCT. The clinical diagnosis of ACS and CT results were analyzed, including segment stenosis score, segment involvement score, 3-vessel plaque score, left main score, calcification score, and remodeling index. The incidences of major adverse cardiac events in follow-up period were also recorded.Results The patients of the diffuse plaque group were older than those of the discrete plaque group (P<0.0001). The diffuse plaque group presented more cases of hypertension, peripheral artery disease, diabetes, and heart failure than discrete plaque group (all P<0.05). All the 5 patients with ST-segment elevation myocardial infarction were found in discrete plaque group. The segment stenosis score of the discrete plaque group was lower than that of the diffuse plaque group (5.15+3.55 vs. 14.91+5.37, P<0.001). The other four scores demonstrated significant inter-group difference as well (all P<0.05). The remodeling index of the discrete plaque group was higher (1.12+0.16 vs. 0.97+0.20, P<0.05). Follow-up data showed that major adverse cardiac events occurred more frequently in diffuse plaque group than in discrete group (29.41% vs.11.48%, P=0.0288).Conclusions Characteristics of discrete and diffuse plaques may be significandy different among different classes of ACS. The diffuse plaque may present higher risk, correlated to higher mortality. The diagnosis of discrete and diffuse plaques by MDCT would provide a new insight into the prognosis and treatment of ACS.

    Full Text Available Heparin has an unpredictable pharmacokinetics and the responses of individuals may vary distinctly. Therefore, different dosing nomograms have been proposed. The aim of this study was to compare two prevalent nomograms to adjust heparin doses in hospitalized patients with acute coronary syndrome. One hundred and forty patients received heparin infusions based on one of two nomograms. Group 1 received a bolus of 80 U/Kg/h and an initial infusion rate of 17 U/Kg/h. In the second group, a bolus of 60 U/Kg (maximum of 4000 U and an initial infusion rate of 12 U/Kg/h (maximum of 900U/h was given. Activated partial thromboplastin time (aPTT was measured at the beginning and every 6 h for 48 hours. The rate of heparin was changed according to each nomogram in order to maintain aPTT in the therapeutic level of 46-70 s. The time to pass threshold was on average 7.63±3.95 h for nomogram 1 and 11.05±4.41 h for the second nomogram (P<0.001. At 48 hours, the proportion of patients in the therapeutic range in group 1 was higher (72.86% vs 45.71%. The time patients stayed at the desired levels was significantly higher in nomogram 1 and they also required fewer heparin rate adjustments (3.41±1.55 vs 4.53±1.63. This study indicated that using nomogram 1 facilitated a more rapid achievement of the therapeutic threshold, higher proportion of patients in the therapeutic range for a longer time, and fewer changes of in the heparin rate.

  14. Comparison of ACUITY and CRUSADE Scores in Predicting Major Bleeding during Acute Coronary Syndrome

    2015-07-01

    Full Text Available Background:The ACUITY and CRUSADE scores are validated models for prediction of major bleeding events in acute coronary syndrome (ACS. However, the comparative performances of these scores are not known.Objective:To compare the accuracy of ACUITY and CRUSADE in predicting major bleeding events during ACS.Methods:This study included 519 patients consecutively admitted for unstable angina, non-ST-elevation or ST-elevation myocardial infarction. The scores were calculated based on admission data. We considered major bleeding events during hospitalization and not related to cardiac surgery, according to the Bleeding Academic Research Consortium (BARC criteria (type 3 or 5: hemodynamic instability, need for transfusion, drop in hemoglobin ≥ 3 g, and intracranial, intraocular or fatal bleeding.Results:Major bleeding was observed in 31 patients (23 caused by femoral puncture, 5 digestive, 3 in other sites, an incidence of 6%. While both scores were associated with bleeding, ACUITY demonstrated better C-statistics (0.73, 95% CI = 0.63 - 0.82 as compared with CRUSADE (0.62, 95% CI = 0.53 - 0.71; p = 0.04. The best performance of ACUITY was also reflected by a net reclassification improvement of + 0.19 (p = 0.02 over CRUSADE’s definition of low or high risk. Exploratory analysis suggested that the presence of the variables ‘age’ and ‘type of ACS’ in ACUITY was the main reason for its superiority.Conclusion:The ACUITY Score is a better predictor of major bleeding when compared with the CRUSADE Score in patients hospitalized for ACS.

    2008-01-01

    Acute coronary syndrome (ACS) is an important public health problem around the world. Since there is a considerable seasonal fluctuation in the incidence of ACS, climatic temperature may have an impact on the onset of this disease. The objective of this study was to assess the relationship between the average daily temperature, diurnal temperature range and emergency room (ER) admissions for ACS in an ER in Taichung City, Taiwan. A longitudinal study was conducted which assessed the correlation of the average daily temperature and the diurnal temperature range to ACS admissions to the ER of the city’s largest hospital. Daily ER admissions for ACS and ambient temperature were collected from 1 January 2000 to 31 March 2003. The Poisson regression model was used in the analysis after adjusting for the effects of holiday, season, and air pollutant concentrations. The results showed that there was a negative significant association between the average daily temperature and ER admissions for ACS. ACS admissions to the ER increased 30% to 70% when the average daily temperature was lower than 26.2°C. A positive association between the diurnal temperature range and ACS admissions was also noted. ACS admissions increased 15% when the diurnal temperature range was over 8.3°C. The data indicate that patients suffering from cardiovascular disease must be made aware of the increased risk posed by lower temperatures and larger changes in temperature. Hospitals and ERs should take into account the increased demand of specific facilities during colder weather and wider temperature variations.

    The incremental prognostic value of plasma levels of C-reactive protein (CRP) in relation to GRACE score has not been established in patients with acute coronary syndrome (ACS) with non-ST segment elevation. To test the hypothesis that CRP measurements at admission increases the prognostic value of GRACE score in patients with ACS. A total of 290 subjects, consecutively admitted for ACS, with plasma material obtained upon admission CRP measurement using a high-sensitivity method (nephelometry) were studied. Cardiovascular outcomes during hospitalization were defined by the combination of death, nonfatal myocardial infarction or nonfatal refractory angina. The incidence of cardiovascular events during hospitalization was 15% (18 deaths, 11 myocardial infarctions, 13 angina episodes) with CRP showing C-statistics of 0.60 (95% CI = 0.51-0.70, p = 0.034) in predicting these outcomes. After adjustment for the GRACE score, elevated CRP (defined as the best cutoff point) tended to be associated with hospital events (OR = 1.89, 95% CI = 0.92 to 3.88, p = 0.08). However, the addition of the variable elevated CRP in the GRACE model did not result in significant increase in C-statistics, which ranged from 0.705 to 0.718 (p = 0.46). Similarly, there was no significant reclassification of risk with the addition of CRP in the predictor model (net reclassification = 5.7 %, p = 0.15). Although CRP is associated with hospital outcomes, this inflammatory marker does not increase the prognostic value of the GRACE score.

    2015-05-01

    Full Text Available Background: Uric acid is an independent risk factor for cardiovascular disease. Hospital admission for ischemic heart disease (IHD is increasing rapidly in our country. Although studies were conducted abroad regarding association of serum uric acid with in-hospital outcomes in patients with acute coronary syndrome (ACS, no data is yet available to show the association in our country. Objective: The objective of this study was to assess the association of serum uric acid level on admission with in-hospital outcomes of the patients with ACS. Materials and Methods: This cross sectional comparative study was done in the Department of Cardiology, Dhaka Medical College Hospital (DMCH from January to December 2012. After proper ethical consideration total 93 ACS patients were enrolled in the study by nonrandom sampling. Serum uric acid of all subjects was measured within 24 hours of admission. Then in-hospital outcomes were observed in all subjects. Results: The frequency of hyperuricemia among ACS patients was 24.7% (22.54% in male and 31.82% in female. Hyperuricemic patients significantly developed heart failure (30.4% vs 11.4%, p=0.032 and conduction defect (13.0% vs 1.4%, p=0.017 than normouricemic subjects. The mean ejection fraction was significantly lower in hyperuricemic patients than patients with normal uric acid level (50.87 ± 10.27% vs 55.94 ± 6.66%. The mean ± SD duration of hospital stay of hyperuricemic group was significantly longer in patients with ACS (8.26 ± 1.18 vs 7.51±1.18 days, p=0.010. Conclusion: The measurement of serum uric acid level, an easily available and inexpensive biochemical tool, might turn out as a valuable risk marker for prediction of in-hospital outcomes in patients with ACS.

    2015-01-01

    Full Text Available Background. An inverse relationship between cardiovascular risk and levels of vitamin D and omega-3 index may exist. Objectives. To evaluate the prognostic utility of serum 25-hydroxyvitamin D [25(OHD] in 871 patients with suspected acute coronary syndrome (ACS and to assess the seasonal correlation between 25(OHD and the omega-3 index in 456 ACS patients from southwestern Norway. Results. In the univariate analysis the hazard ratio (HR at 2-year follow-up for all-cause mortality in the highest as compared to the lowest quartile of 25(OHD in the total population was 0.61 (95% confidence interval (CI, 0.37–1.00, P=0.050. At 7-year follow-up, the corresponding HR for all-cause mortality was 0.66 (95% CI, 0.49–0.90, P=0.008, and for females alone 0.51 (95% CI, 0.32–0.83, P=0.006. Quartile survival did not differ in the multivariable analysis, whereas 25(OHD < 40 nM (<16 ng/mL was found to be independently related to mortality. Seasonal differences in 25(OHD, but not for the omega-3 index, were noted, and the two biomarkers were positively correlated, especially during winter-spring; Pearson’s correlation coefficient was 0.358, P<0.001. Conclusion. Vitamin D levels are related to survival, especially in females, and correlate with the omega-3 index.

  20. Newer non-vitamin K-antagonist direct oral anticoagulants in acute coronary syndromes

    Andrea Rubboli

    2013-12-01

    Full Text Available standard dual antiplatelet therapy (DAPT of aspirin and clopidogrel is associated with a substantial absolute incidence of adverse events, including death, myocardial infarction and stroke after an acute coronary syndrome (ACs. Combination therapy of an oral anticoagulant and DAPT has been previously proposed in order to improve efficacy, but has not gained popularity owing to the cumbersome management of vitamin K-antagonists (VKA. The recent introduction of newer, non-VKA, direct oral anticoagulants (NOAC, including dabigatran, apixaban, and rivaroxaban, has renewed the interest in combination therapy, owing to the more favorable pharmacokinetic and pharmacodynamic profiles of these drugs. Whereas phase II studies with dabigatran, apixaban, and rivaroxaban have consistently shown an increased bleeding risk with combination therapy, a potential increased efficacy has emerged for apixaban and rivaroxaban, thereby prompting phase III studies, namely APPRAIsE-2 with apixaban and ATLAs ACs 2-TIMI 51 with rivaroxaban. Both APPRAIsE-2 and ATLAs ACs 2-TIMI 51 studies confirmed a dose-dependent increase in major, including intracranial, bleeding with apixaban and rivaroxaban when combined with DAPT. Low-dose rivaroxaban on the other hand, was associated with significantly higher efficacy on the occurrence of combined cardiovascular death, myocardial infarction, or stroke, as well as of cardiovascular death, myocardial infarction and stent thrombosis. Owing to the persistent uncertainty regarding the net clinical benefit of combined therapy of NOAC, namely low-dose rivaroxaban, and DAPT, further studies are warranted to identify the ACs patient who will benefit most from such treatment, also in comparison to current standard DAPT of aspirin and prasugrel or ticagrelor.

  1. Role of novel and emerging oral anticoagulants for secondary prevention of acute coronary syndromes.

    2014-06-01

    Dual antiplatelet therapy has become a mainstay of long-term management of patients after an acute coronary syndrome (ACS). Mortality for these patients remains high despite current evidence-based treatment strategies. The coagulation cascade plays a role in the pathophysiology of ACS, and trials with warfarin in combination with dual antiplatelet therapy have found decreased rates of ischemic events at the expense of increased bleeding risk. Novel oral anticoagulants (NOACs) in the direct factor Xa (FXa) inhibitor and direct thrombin inhibitor (DTI) categories have been evaluated in combination with standard post-ACS therapy. Rivaroxaban, a FXa inhibitor, reduced the rates of ischemic events but increased major bleeding rates. Apixaban did not decrease the rates of ischemic events and also increased major bleeding rates. Other FXa inhibitors have not been studied in the long-term management of ACS (e.g., otamixaban), are not currently being studied in ongoing phase III trials (e.g., TAK-442), or have been discontinued by the manufacturer (e.g., darexaban). The DTI dabigatran had a 2- to 4-fold increased risk of major bleeding with unclear benefit for reducing ischemic events. The factor IXa inhibitor pegnivacogin is an RNA-based aptamer that has been studied in patients undergoing cardiac catheterization but has not been studied for long-term post-ACS management. The European Society of Cardiology Working Group on Thrombosis recommends the use of newer antiplatelet agents over addition of NOACs. Additional guidelines are available to guide management in patients requiring triple antithrombotic therapy but do not provide definitive recommendations on NOACs. Many questions remain about the place of NOACs for long-term post-ACS management. Recent trials have evaluated double versus triple antithrombotic therapy to balance efficacy and bleeding risk, but they did not include NOACs. It also remains unclear if NOACs hold a place in post-ACS therapy in the era of more

    Full Text Available A 27-year old male presented with acute inferior wall myocardial infarction. Coronary angiogram revealed normal left coronary arteries and a giant coronary aneurysm in Right coronary artery (RCA. Primary angioplasty of RCA was performed. Large thrombus burden was retrieved with aspiration device and coronary flow restored. However, despite best efforts some thrombus remained and decision to stent was deferred to a later date. Dimensions of aneurysm on quantitative coronary angiogram were 16 mm in width and 43 mm in length. Two weeks later coronary angiogram revealed normal flow in RCA without any angiographically visible thrombus. PCI was performed with two 3.0 and times; 28 mm covered stents, graft master (JoStent deployed across the aneurysm, overlapping each other. This completely sealed the aneurysm and intravascular ultrasound confirmed no leakage through the covered stents. Patient remains asymptomatic 2 months post procedure on triple antiplatelet therapy.

  3. Nephrotic syndrome: a rare cause of acute coronary syndrome in a child

    Patients with nephrotic syndrome are at risk of developing thrombosis in both veins and arteries. Various manifestations in different organs have been reported. Thrombi in heart seen, associated with multi organ thrombosis have been reported on autopsy earlier, but only once in a living patient with nephrotic syndrome. Here, we report a 13 years old boy with steroid-resistant nephrotic syndrome, who developed an asymptomatic but potentially hazardous large intracardiac thrombus. The child developed nephrotic syndrome at the age of 9 years and had multiple recurrences. At the age of 13 years, he developed myocardial infarction (MI) due to embolism from a large intracardiac thrombus. Later on, he was treated with heparin and warfarin anticoagulation. (author)

  4. Acute thrombosis during left main stenting using tap technique in a patient presenting with non-ST-segment elevation acute coronary syndrome

    This case reports the sudden development of large burden of thrombi in the left anterior descending coronary artery immediately following distal left main stenting using TAP technique in a middle aged man who presented with non ST-segment elevation acute coronary syndrome despite having been administered 7,500 units of unfractionated heparin and being given 325 mg of aspirin and 60 mg of prasugrel prior to the procedure. The thrombi were managed effectively by giving an intra-coronary high bolus dose of tirofiban (25 mcg/kg) without the need for catheter thrombus extraction. Tirofiban intra-venous infusion was maintained for 18 hours, and the patient was discharged in stable condition on the third day. Importantly there is no controlled study on upstream administration of glycoprotein IIb/IIIa inhibitors in addition to the newer more potent anti-platelet agents in patients with unprotected distal left main disease presenting with non ST-segment elevation acute coronary syndrome, nor is there any data on safety and efficacy of mandatory usage of injectable anti-platelet agents at the start of a procedure in a catheterization laboratory in such a setting

    Thrombosis is the most important pathological mechanism of acute coronary syndromes (ACS). In addition to standard antithrombotic treatment with aspirin and heparin, clopidogrel, glycoprotein IIb/IIIa inhibitors, and low-molecular-weight have a therapeutic benefit in ACS patients. Updated American College of Cardiology/American Heart Association guidelines for the management of ACS patients were published in mid-2002, and this article summarizes the rationale for the recommendations outlined in these guidelines for the use of antithrombotic and antiplatelet therapies.

    The increasing life expectancy in older adults and the better survival of patients with multiple pathologies require the capability to treat complex clinical conditions with an increased risk of iatrogenic complications. Nevertheless, recent improvements in the pharmacological and interventional treatment of acute coronary syndrome (ACS) have promoted a shift from therapeutic nihilism to a more active management of complex ACS cases. Despite the paucity of specific randomized clinical trials, observational studies seem to show benefit of an early invasive treatment in these patients. This approach requires close cooperation of clinical intensivists, interventional cardiologists and cardiovascular surgeons either in a specialized heart center or in a network of hospitals.

    2006-09-01

    In the case of non-ST-segment elevation acute coronary syndromes (NSTE-ACSs), the acute use of certain antiplatelet agents is complicated by concerns about perioperative bleeding risks in patients requiring coronary artery bypass grafting (CABG) during the index hospitalization. As a result, clinicians often withhold potentially useful agents, such as clopidogrel, before determining patients' coronary anatomy. An accurate predictive model could allow for a better balance of this safety concern with the demonstrated benefits of agents such as clopidogrel. To create an accurate decision-making tool that would assess, at hospital presentation, the need for CABG in patients with NSTE-ACSs, we studied 61,974 high-risk patients with NSTE-ACS admitted to 311 CABG-capable hospitals participating in Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) from 2001 to 2003. A total of 8,395 patients (14%) underwent CABG during their initial hospital stay. A multivariate model was developed and identified 13 presenting clinical characteristics significantly associated with the likelihood of CABG (previous CABG, male gender, previous heart failure, diabetes, hyperlipidemia, renal insufficiency, ST depression and transient ST elevation, age > or = 75 years, previous percutaneous coronary intervention, family history of coronary artery disease, hypertension, trends in CABG rates, and previous stroke). This model had only modest predictive accuracy and calibration (c-index = 0.67). In conclusion, although certain presenting clinical features are associated with an increased likelihood of CABG in patients with NSTE-ACSs during the index hospitalization, it remains difficult to reliably identify, before diagnostic angiography, those who will subsequently undergo surgical revascularization.

    Coronary heart disease (CHD) is an important cause of death in the world.Among them,acute coronary syndrome (ACS) is a type of CHD that has a high mortality rate.Microparticles (MPs) are tiny particles formed in the process of cell activation and apoptosis,carrying specific markers of their mother cells.There is more and more evidence that MPs derived from endothelial cells,platelets,white blood cells and other cells are closely related to the formation of ACS.Through a variety of pathways,they take part in endotheial cell damage,vascular dysfunction,plaque erosion and rupture,and thrombosis.The findings of MPs enrich our knowledge about ACS,and may provide a new approach to the treatment of ACS.

  16. Direct oral anticoagulant use and stent thrombosis following an acute coronary syndrome: A potential new pharmacological option?

    Welsh, Robert C; Zeymer, Uwe; Tarrantini, Giuseppe

    2016-05-01

    With the evolution of techniques and pharmacological strategies in percutaneous coronary intervention, significant advances have been made towards reducing the risk of in-stent restenosis and improving patient outcomes. However, in spite of these advances, stent thrombosis remains a deadly complication of stent implantation. The fundamental challenge in implementing a combined anticoagulant and antiplatelet strategy is balancing the risk of bleeding with the enhanced efficacy of therapy on both pathways. Results from the ATLAS ACS 2-TIMI 51 trial suggest that the addition of rivaroxaban 2.5mg twice daily to standard antiplatelet therapy may achieve this desired balance alongside careful patient selection. This review considers the clinical burden and pathology of stent thrombosis, oral antithrombotic strategies to reduce stent thrombosis, and what findings from recent trials could mean for the long-term management of patients with an acute coronary syndrome.

    2011-01-01

    Full Text Available Background. Recent intravascular ultrasound (IVUS studies have demonstrated that hypoechoic plaque with deep ultrasound attenuation despite absence of bright calcium is common in acute coronary syndrome. Such “attenuated plaque” may be an IVUS characteristic of unstable lesion. Methods. We used optical coherence tomography (OCT in 104 patients with unstable angina to compare lesion characteristics between IVUS-detected attenuated plaque and nonattenuated plaque. Results. IVUS-detected attenuated plaque was observed in 41 (39% patients. OCT-detected lipidic plaque (88% versus 49%, <0.001, thin-cap fibroatheroma (48% versus 16%, <0.001, plaque rupture (44% versus 11%, <0.001, and intracoronary thrombus (54% versus 17%, <0.001 were more often seen in IVUS-detected attenuated plaques compared with nonattenuated plaques. Conclusions. IVUS-detected attenuated plaque has many characteristics of unstable coronary lesion. The presence of attended plaque might be an important marker of lesion instability.

  19. Reliability of Predicting Early Hospital Readmission After Discharge for an Acute Coronary Syndrome Using Claims-Based Data.

    McManus, David D; Saczynski, Jane S; Lessard, Darleen; Waring, Molly E; Allison, Jeroan; Parish, David C; Goldberg, Robert J; Ash, Arlene; Kiefe, Catarina I

    Early rehospitalization after discharge for an acute coronary syndrome, including acute myocardial infarction (AMI), is generally considered undesirable. The Centers for Medicare and Medicaid Services (CMS) base hospital financial incentives on risk-adjusted readmission rates after AMI, using claims data in its adjustment models. Little is known about the contribution to readmission risk of factors not captured by claims. For 804 consecutive patients >65 years discharged in 2011 to 2013 from 6 hospitals in Massachusetts and Georgia after an acute coronary syndrome, we compared a CMS-like readmission prediction model with an enhanced model incorporating additional clinical, psychosocial, and sociodemographic characteristics, after principal components analysis. Mean age was 73 years, 38% were women, 25% college educated, and 32% had a previous AMI; all-cause rehospitalization occurred within 30 days for 13%. In the enhanced model, previous coronary intervention (odds ratio [OR] = 2.05, 95% confidence interval [CI] 1.34 to 3.16; chronic kidney disease OR 1.89, 95% CI 1.15 to 3.10; low health literacy OR 1.75, 95% CI 1.14 to 2.69), lower serum sodium levels, and current nonsmoker status were positively associated with readmission. The discriminative ability of the enhanced versus the claims-based model was higher without evidence of overfitting. For example, for patients in the highest deciles of readmission likelihood, observed readmissions occurred in 24% for the claims-based model and 33% for the enhanced model. In conclusion, readmission may be influenced by measurable factors not in CMS' claims-based models and not controllable by hospitals. Incorporating additional factors into risk-adjusted readmission models may improve their accuracy and validity for use as indicators of hospital quality. PMID:26718235

  20. Improving the management of non-ST elevation acute coronary syndromes: systematic evaluation of a quality improvement programme European QUality Improvement Programme for Acute Coronary Syndrome: The EQUIP-ACS project protocol and design

    Bardaji Alfredo

    2010-01-01

    Full Text Available Abstract Background Acute coronary syndromes, including myocardial infarction and unstable angina, are important causes of premature mortality, morbidity and hospital admissions. Acute coronary syndromes consume large amounts of health care resources, and have a major negative economic and social impact through days lost at work, support for disability, and coping with the psychological consequences of illness. Several registries have shown that evidence based treatments are under-utilised in this patient population, particularly in high-risk patients. There is evidence that systematic educational programmes can lead to improvement in the management of these patients. Since application of the results of important clinical trials and expert clinical guidelines into clinical practice leads to improved patient care and outcomes, we propose to test a quality improvement programme in a general group of hospitals in Europe. Methods/Design This will be a multi-centre cluster-randomised study in 5 European countries: France, Spain, Poland, Italy and the UK. Thirty eight hospitals will be randomised to receive a quality improvement programme or no quality improvement programme. Centres will enter data for all eligible non-ST segment elevation acute coronary syndrome patients admitted to their hospital for a period of approximately 10 months onto the study database and the sample size is estimated at 2,000-4,000 patients. The primary outcome is a composite of eight measures to assess aggregate potential for improvement in the management and treatment of this patient population (risk stratification, early coronary angiography, anticoagulation, beta-blockers, statins, ACE-inhibitors, clopidogrel as a loading dose and at discharge. After the quality improvement programme, each of the eight measures will be compared between the two groups, correcting for cluster effect. Discussion If we can demonstrate important improvements in the quality of patient care as

    There is turnover of type I collagen during tissue repair. The degradation of type I collagen by matrix metalloproteinases (MMPs) is reflected by serum ICTP and that by cathepsins by CTX-I. There is evidence for increases in ICTP after acute coronary syndromes (ACS) and in CTX-I during fracture repair. The involvement of the MMP pathway in fracture repair and cathepsins after myocardial infarction is unclear. We studied 74 men; 22 were admitted to the hospital on the day of their ACS (ST or non-ST elevation myocardial infarction) (mean age 56 years, range 39 to 82) and 9 attended hospital on the day of their tibial shaft fracture (mean age 33 years, range 21 to 79); we had 43 age-matched controls (mean age 54 years, range 20 to 82). Subjects with ACS and tibial shaft fracture were followed up for up to one year; control subjects were used to establish a reference interval. We measured serum ICTP by ELISA (reference interval 1.1 to 17.6 ng/mL) and CTX-I by chemiluminescence (reference interval 0.094 to 0.991 ng/mL). After ACS, the mean ICTP increased from 5.41 to 6.60 ng/mL within one day of admission (p<0.05); the mean CTX-I increased from 0.263 to 0.414 ng/mL (p<0.05). In two cases, the CTX increased to above the reference interval. After tibial shaft fracture, the mean ICTP increased from 5.51 to maximum of 8.71 ng/mL within 28 days of admission (p<0.01); the mean CTX increased from 0.200 to 0.374 ng/mL (p<0.001). In four cases, the CTX increased to above the reference interval. We conclude that the MMP and cathepsin pathways are both implicated in tissue repair in the bone and heart. This may have clinical implications; drugs that block either pathway (TIMPs, cathepsin K inhibitors) may affect the repair of both tissues. PMID:25193029

  2. Balancing Potency of Platelet Inhibition with Bleeding Risk in the Early Treatment of Acute Coronary Syndrome

    Slattery, David E

    2009-08-01

    Full Text Available Objective: To review available evidence and examine issues surrounding the use of advanced antiplatelet therapy in an effort to provide a practical guide for emergency physicians caring for patients with acute coronary syndromes (ACS.Data Sources: American College of Cardiology/American Heart Association (ACC/AHA 2007 guidelines for the management of patients with unstable angina (UA and non-ST-segment elevation myocardial infarction (NSTEMI, AHA/ACC 2007 focused update for the management of patients with STEMI, selected clinical articles identified through the PubMed database (1965-February 2008, and manual searches for relevant articles identified from those retrieved.Study Selection: English-language controlled studies and randomized clinical trials that assessed the efficacy and safety of antiplatelet therapy in treating patients with all ACS manifestations.Data Extraction and Synthesis: Clinical data, including treatment regimens and patient demographics and outcomes, were extracted and critically analyzed from the selected studies and clinical trials. Pertinent data from relevant patient registries were also evaluated to assess current clinical practice.Conclusions: As platelet activation and aggregation are central to ACS pathology, antiplatelet agents are critical to early treatment. A widely accepted first-line treatment is aspirin, which acts to decrease platelet activation via inhibition of thromboxane A2 synthesis. Thienopyridines, which inhibit ADP-induced platelet activation, and glycoprotein (GP receptor antagonists, which bind to platelet GP IIb/IIIa receptors and hinder their role in platelet aggregation and thrombus formation, provide complementary mechanisms of platelet inhibition and are often employed in combination with aspirin. While the higher levels of platelet inhibition that accompany combination therapy improve protection against ischemic and peri-procedural events, the risk of bleeding is also increased. Thus, the

    Full Text Available Siti-Zainora Mohd-Zulkefli, Marhanis-Salihah Omar, Adyani Md-Redzuan Faculty of Pharmacy, Universiti Kebangsaan Malaysia, Kuala Lumpur, Malaysia Background: The incidence of acute coronary syndrome (ACS, one of the most common cardiovascular diseases, is high. Lipid goal attainment is one of the important factors to reduce the risk of recurrent heart attack. Identification of factors influencing lipid goal attainment such as age, female, race, underlying comorbidities, intensity of lipid-lowering therapy, patients’ knowledge, and patients’ belief about medicine would be beneficial in achieving the lipid goal. This study is aimed to determine lipid profile attainment and prescribing pattern of lipid-lowering therapy as well as to identify factors influencing lipid profile attainment among ACS patients.Patients and methods: This researcher-assisted cross-sectional survey was carried out at a cardiology clinic in a tertiary hospital from March to May 2015.Results: A total of 101 ACS patients were involved in this study. The mean values for low-density lipoprotein cholesterol (LDL-C and high-density lipoprotein cholesterol levels were 2.75 (0.82 mmol/L and 1.14 (0.27 mmol/L, respectively, while the median value for triglyceride level was 2.75 (0.82 mmol/L. Only 15.8% of our participants achieved the targeted LDL-C. Simvastatin 20 mg was the most common regimen prescribed. Predictors for better LDL-C attainment were younger age (β=-0.228; P=0.032 and higher knowledge score (β=-0.255; P=0.049, while predictors for high-density lipoprotein cholesterol attainment were male (β=0.268; P=0.006, smoking (β=-0.192; P=0.045, and higher knowledge score (β=-0.195; P=0.039. Smoking (β=-0.361; P<0.0001 was the only predictor for higher triglyceride level.Conclusion: Younger age, female, lower knowledge score, and smoking status are good predictors for lipid attainment among ACS patients.

Methods: Plasma ADM, ET-1 and GMP-140 levels were measured with RIA in (1) 31 cases of ACS with unstable angina pectoris (UAP) or non-ST segment elevation myocardial infarction (NSTEMI), (2) 32 cases of ACS with ST segment elevation myocardial infarction (STEMI), (3) 31 patients with stable angina pectoris (SAP) and, (4) 33 controls. Results: The plasma ADM, ET-1 and GMP-140 levels in both patient groups with UAP/NSTEMI and STEMI were significantly higher than those in controls (P0.05). However, the plasma levels of ADM, ET-1 and GMP-140 in the three groups of patients (2 groups of ACS and 1 group of SAP) were significantly different from each other (P< 0.01). Plasma levels of ADM, ET-1 and GMP-140 were mutually positively correlated. Conclusion: Changes of plasma levels of ADM, ET-1 and GMP-140 might reflect the severity of acute coronary syndrome and might serve as a marker for instability of the atheromatous plaques. (authors)

    For many years, ergotamine has been used for the acute treatment of migraine. Ergotamine may produce coronary vasospasm, which is often associated with ischemic electrocardiography changes and angina pectoris. A 62-year-old woman who was admitted to the emergency department because of chest pain is described. She had a history of severe migraine attacks and started to use ergotamine tartrate 0.75 mg daily the day before. Electrocardiography revealed sinus tachycardia with left anterior hemiblock and T wave inversion in the precordial leads. Cardiac biomarker levels were elevated. After discontinuation of the drug and initiation of vasodilator treatment, her chest pain resolved. Patients with migraine may have an underlying vasospastic disorder predisposing them to coronary artery spasm. Physicians should be alerted to potential cardiac vasospastic effects of low-dose ergotamine in the treatment of migraine. PMID:23204901

    2015-01-01

    Full Text Available Acute Respiratory Distress Syndrome (ARDS is a potential complication of cardiac surgery, given that patients undergoing CABG frequently have hypoxemia and pulmonary dysfunction during initial hours after surgery. Thus, ARDS criteria in these patients are more likely to be positive while these criteria may not match the patient`s clinical picture. We aimed to investigate frequency of rapid onset hypoxemia in Pressure of Arterial Oxygen to Fractional Inspired Oxygen Concentration (PaO2/FiO2 less than 200 and diffuse pulmonary infiltrates as two diagnostic criteria forwards and compared these criteria with the clinical picture of the patients after Coronary Artery Bypass Graft (CABG in this study. The study was prospective case series which carried out in about six months. All patients admitted to intensive care unit of Tehran Heart Center, who had undergone CABG on cardiopulmonary pump (CPB recruited in the study. After considering inclusion criteria, age, sex, duration of intubation, arterial blood gas and chest radiography, on 24 hours and 48 hours after admission to the ICU were recorded. Then, patients with rapid onset of hypoxemia (PaO2/FiO2≤200mmHg and diffuse pulmonary infiltrates and without sign or symptoms of obvious heart failure (probable positive ARDS cases criteria were recorded and comparison between these probable positive cases with clinician`s clinical diagnosis (blinded to the study was performed. In this study, a total of 300 patients after on-pump coronary artery bypass surgery were included. Postoperatively, 2 (0.66 % in the 24 hours and 4 (1.33% patients in 48 hours after surgery were positive for the two ARDS criteria according to the checklists, but; nobody had saved persistently ARDS criteria persistently during 48 hours after surgery. At the same time, clinician did not report any case of ARDS among 300 patients. In this study patients with ARDS criteria had no significant differences in age (P.value=0.937 and sex (P

  8. Critical appraisal of ticagrelor in the management of acute coronary syndrome

    Nawarskas JJ

    Full Text Available James J Nawarskas, Stanley S SnowdenUniversity of New Mexico College of Pharmacy, Albuquerque, NM, USAAbstract: Ticagrelor is a novel P2Y12 receptor antagonist which, like clopidogrel and prasugrel, functions by blocking adenosine diphosphate-mediated platelet aggregation. However, unlike the aforementioned agents, the binding of ticagrelor to this receptor is reversible. Ticagrelor is also believed to mediate some of its beneficial effects by augmenting the effects of adenosine, which is another unique pharmacologic property of this drug. In terms of antiplatelet effect, ticagrelor is more potent than clopidogrel and produces a faster and stronger inhibition of platelet aggregation. This may also be an advantage of ticagrelor over prasugrel, but this has not been adequately studied. Due to the reversible nature of the binding of ticagrelor to the platelet receptor, ticagrelor has a relatively fast offset of effect, with platelet aggregation approaching pretreatment levels about 3 days after discontinuation of therapy. This has advantages in patients requiring invasive procedures, but also makes medication adherence very important in order to be able to maintain an effective antiplatelet effect. Ticagrelor has been shown to be clinically superior to clopidogrel when given to patients with an acute coronary syndrome, resulting in significantly lower rates of myocardial infarction and vascular death. However, ticagrelor is indicated to be administered with aspirin, and the clinical benefits of ticagrelor may be less when daily dosages of aspirin exceed 100 mg. As expected, bleeding is the most common adverse effect with ticagrelor, although it occurs at rates comparable with those seen for clopidogrel with the exception of noncoronary artery bypass graft-related major bleeding and fatal intracranial bleeds, the latter of which occurs only rarely. Dyspnea is another common adverse effect with ticagrelor, although this is usually not severe and

  14. Studies on the relationship between plasma CRP and TNF-α, IL-1β levels in aged patients with acute coronary syndrome

    Objective: To investigate the relationship between plasma TNF-α, IL-1β and CRP levels in aged patients with coronary heart disease and to define the inflammation marker which might recognize and predict acute coronary syndrome. Methods: Radioimmunoassay was used to detect plasma levels of TNF-α, IL-1β and CRP. Results: Plasma levels of TNF-α and IL-β in patients with acute coronary syndrome (ACS) were significantly higher than those in controls (p<0.05; p<0.01) and stable coronary heart disease (SCHD) (p<0.05; p<0.01). Plasma CRP levels in patients with ACS (7.99 +- 11.9 ml/L) were also significantly higher than those in controls (0.99 +- 1.5 mg/L; p<0.01) and patients with SCHD (2.71 +- 5.45 mg/L; p<0.05). There was positive correlation between CRP level and TNF-α (r=0.0545; p<0.01) as well as IL-β (r=0.31, p<0.05). Conclusion: The abnormal expression of cytokines in aged patients with coronary heart disease was correlative to inflammation marker CRP, which suggested that the abnormal expression to the occurrence of acute coronary syndrome and might serve as a marker of unstable atherosclerosis plaque

    Global Registry of Acute Coronary Events (GRACE) risk score and red blood cell distribution width (RDW) content can both independently predict major adverse cardiac events (MACEs) in patients with acute coronary syndrome (ACS). We investigated the combined predictive value of RDW and GRACE risk score for cardiovascular events in patients with ACS undergoing percutaneous coronary intervention (PCI) for the first time. We enrolled 480 ACS patients. During a median follow-up time of 37.2 months, 70 (14.58%) patients experienced MACEs. Patients were divided into tertiles according to the baseline RDW content (11.30–12.90, 13.00–13.50, 13.60–16.40). GRACE score was positively correlated with RDW content. Multivariate Cox analysis showed that both GRACE score and RDW content were independent predictors of MACEs (hazard ratio 1.039; 95% confidence interval [CI] 1.024–1.055; p < 0.001; 1.699; 1.294–2.232; p < 0.001; respectively). Furthermore, Kaplan–Meier analysis demonstrated that the risk of MACEs increased with increasing RDW content (p < 0.001). For GRACE score alone, the area under the receiver operating characteristic (ROC) curve for MACEs was 0.749 (95% CI: 0.707–0.787). The area under the ROC curve for MACEs increased to 0.805 (0.766–0.839, p = 0.034) after adding RDW content. The incremental predictive value of combining RDW content and GRACE risk score was significantly improved, also shown by the net reclassification improvement (NRI = 0.352, p < 0.001) and integrated discrimination improvement (IDI = 0.023, p = 0.002). Combining the predictive value of RDW and GRACE risk score yielded a more accurate predictive value for long-term cardiovascular events in ACS patients who underwent PCI as compared to each measure alone.

  18. Early characterization of atherosclerotic coronary plaques with multidetector computed tomography in patients with acute coronary syndrome. A comparative study with intravascular ultrasound

    We compared 16-slice computed tomography (CT) with intravascular ultrasound (IVUS) in their ability to identify the culprit lesion, and to assess plaque characterization and vascular remodelling in acute coronary syndrome (ACS). Twenty patients were prospectively studied. Coronary plaque identification and characterization were compared using 16-slice CT and 40-MHz catheter-based IVUS. Minimum lumen area (MLA), cross-sectional vessel area (CVA) and vessel remodelling were determined for each comparable lesion. One hundred and sixty-nine segments were compared and 84 plaques analysed. Sixteen-slice CT detected 95% of culprit lesions (19/20). No feature suggestive of plaque rupture was detected by 16-slice CT. Attenuation measurements within all lesions revealed different values for hypoechoic (38 ± 33 HU), hyperechoic (94 ± 44 HU), and calcified plaques (561 ± 216 HU), (P < 0.001). Agreement between 16-slice CT and IVUS on measuring MLA and CVA was evaluated using Bland-Altman analysis. Pearson and intra-class coefficient (ICC) were 0.81 and 0.70 for MLA, and 0.81 and 0.36 for CVA, for 16-slice CT and IVUS, respectively. Agreement between both techniques for vessel positive remodelling was moderate (kappa 0.54, P < 0.001). Sixteen-slice CT has shown moderate accuracy in quantifying and characterizing coronary plaques compared with IVUS. Spatial resolution of 16-slice CT remains a major limitation, however, to accurately assess the complex lesions involved in ACS. (orig.)

    Some evidence indicates the deterioration of the cardiovascular system during space storms. It is plausible that the space weather conditions during and after hospital admission may affect the risk of coronary events in patients with acute coronary syndromes (ACS). We analyzed the data of 1400 ACS patients who were admitted to the Hospital Lithuanian University of Health Sciences, and who survived for more than 4 days. We evaluated the associations between geomagnetic storms (GS), solar proton events (SPE), and solar flares (SF) that occurred 0-3 days before and after hospital admission and the risk of cardiovascular death (CAD), non-fatal ACS, and coronary artery bypass grafting (CABG) during a period of 1 year; the evaluation was based on the multivariate logistic model, controlling for clinical data. After adjustment for clinical variables, GS occurring in conjunction with SF 1 day before admission increased the risk of CAD by over 2.5 times. GS 2 days after SPE occurred 1 day after admission increased the risk of CAD and CABG by over 2.8 times. The risk of CABG increased by over 2 times in patients admitted during the day of GS and 1 day after SPE. The risk of ACS was by over 1.63 times higher for patients admitted 1 day before or after solar flares.

  1. Contemporary Management of Coronary Artery Disease and Acute Coronary Syndrome in Patients with Chronic Kidney Disease and End-Stage Renal Disease

    Huang, Chin-Chou; Chen, Jaw-Wen

    2013-01-01

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

  9. Detection of vulnerable plaques rather than the culprit lesions in patients with acute coronary syndrome using virtual histology intravascular ultrasound imaging

    QIAN Ju-ying

    2009-01-01

    @@ Pathology and postmortem studies have reported that the most important mechanism of acute coronary syndrome (ACS) is the rupture of a vulnerable plaque and subsequent thrombus formation. Such events commonly arise from the non-flow limiting atherosclerotic lesions which are prone to rupture. Thin-cap fibroatheromas (TCFA) are the most common type of vulnerable plaque. As the widely used technique for the detection of coronary arterial diseases, coronary angiography has intrinsic limitations since it only portrays the contrast agent-filled contour of the lumen and provides little information on the vessel wall and even less the characteristics of the plaques.

    Objective: To evaluate the economic impact of integrating coronary CT angiography (cCTA) or whole chest “triple-rule-out” CTA (TRO-CTA) in the work-up of patients with acute chest pain. Materials and methods: 100 consecutive emergency department patients with acute chest pain and an intermediate cardiac risk for ACS underwent cCTA or TRO-CTA (cCTA group). Diagnostic performance, rate and length of hospitalization, hospital costs, hospital reimbursement and hospital profit were analyzed. All findings were compared to those of 100 different patients with acute chest pain that were evaluated with a standard of care (SOC) diagnostic algorithm (SOC group) that did not include cCTA. Diagnostic performance (“safety”) of both algorithms was defined as the absence of major adverse cardiac events (MACE) over a 90-day follow-up period. Results: In the cCTA group 60/100 patients were safely discharged at the same day. 19/100 patients were hospitalized due to significant coronary stenosis on cCTA, which was confirmed by invasive coronary catheterization (ICC) in 17/19 patients. Relevant non-coronary disease that led to hospitalization were found in 21 patients of the cCTA group. In the SOC group all patients were hospitalized. 87 of these hospitalized patients underwent ICC for exclusion of coronary artery stenosis. A significant coronary artery stenosis was found in only 25 of these patients. Within the cCTA group no patient suffered from MACE over the 90-day follow-up period. In the SOC group 2 patients were rehospitalized during the 90-day follow-up period due to recurrent chest pain and 1 patient because of a pseudoaneurym of the left femoral artery after ICC. The median hospital costs per patient were significantly lower in the cCTA group than in the SOC group (428.9€ vs. 1575.0€, p < 0.001). The median reimbursement of the cCTA group was less compared to the SOC group (589.8€ vs. 2412.1€, p < 0.001) and patients in the cCTA group gained less profit than

Casi siempre ha sido la propia enfermedad y no tanto el padecimiento del paciente la auténtica protagonista de nuestros escritos. Con nuestro presente trabajo pretendemos adentrarnos en aquellas dimensiones más subjetivas de la enfermedad, es decir, en el padecimiento y en el "sickness". Metodología: Se trata de un estudio cualitativo de tipo descriptivo en el que presentamos algunos de los datos más significativos de los relatos de nuestros pacientes con Síndrome Coronario Agudo. Resultados: los hemos agrupado en siete categorías temáticas: dolor, miedo, impacto en la familia, impacto en la actividad laboral, impacto en las actividades recreativas, impacto en el rol de cuidador y posibles causas.  Discusión: Se comparan los resultados con los de otros trabajos que han estudiado también el Síndrome Coronario Agudo desde diversas perspectivas: la sexualidad, los descriptores verbales, el dolor, y los testimonios de mujeres mexicanas que han pasado por esta misma situación.Introduction.

  14. When is the Best Time for the Second Antiplatelet Agent in Non-St Elevation Acute Coronary Syndrome?

    Pedro Gabriel Melo de Barros e Silva

    2016-03-01

    Full Text Available Abstract Dual antiplatelet therapy is a well-established treatment in patients with non-ST elevation acute coronary syndrome (NSTE-ACS, with class I of recommendation (level of evidence A in current national and international guidelines. Nonetheless, these guidelines are not precise or consensual regarding the best time to start the second antiplatelet agent. The evidences are conflicting, and after more than a decade using clopidogrel in this scenario, benefits from the routine pretreatment, i.e. without knowing the coronary anatomy, with dual antiplatelet therapy remain uncertain. The recommendation for the upfront treatment with clopidogrel in NSTE-ACS is based on the reduction of non-fatal events in studies that used the conservative strategy with eventual invasive stratification, after many days of the acute event. This approach is different from the current management of these patients, considering the established benefits from the early invasive strategy, especially in moderate to high-risk patients. The only randomized study to date that specifically tested the pretreatment in NSTE-ACS in the context of early invasive strategy, used prasugrel, and it did not show any benefit in reducing ischemic events with pretreatment. On the contrary, its administration increased the risk of bleeding events. This study has brought the pretreatment again into discussion, and led to changes in recent guidelines of the American and European cardiology societies. In this paper, the authors review the main evidence of the pretreatment with dual antiplatelet therapy in NSTE-ACS.

Ticagrelor has shown benefits in clinical trials. Its rapid onset of platelet inhibition and short half-life make it an attractive alternative to thienopyridines, especially when rapid inhibition of platelet aggregation or its quick reversal are required.Keywords: platelet, acute coronary syndromes, antiplatelet, coronary artery disease, percutaneous coronary intervention, stent

    Full Text Available Background: Prasugrel is recommended over clopidogrel in poor/intermediate CYP2C19 metabolizers with acute coronary syndrome (ACS and planned percutaneous coronary intervention (PCI, reducing the risk of ischemic events. CYP2C19 genetic testing can guide antiplatelet therapy in ACS patients. Objective: The purpose of this study was to evaluate the cost-utility of genotype-guided treatment, compared with prasugrel or generic clopidogrel treatment without genotyping, from the US healthcare provider’s perspective. Methods: A decision model was developed to project lifetime economic and humanistic burden associated with clinical outcomes (myocardial infarction [MI], stroke and major bleeding for the three strategies in patients with ACS. Probabilities, costs and age-adjusted quality of life were identified through systematic literature review. Incremental cost-utility ratios (ICURs were calculated for the treatment strategies, with quality-adjusted life years (QALYs as the primary effectiveness outcome. Relative risk of developing myocardial infarction and stroke between patients with and without variant CYP2C19 when receiving clopidogrel were estimated to be 1.34 and 3.66, respectively. One-way and probabilistic sensitivity analyses were performed. Results: Clopidogrel cost USD19,147 and provided 10.03 QALYs versus prasugrel (USD21,425, 10.04 QALYs and genotype-guided therapy (USD19,231, 10.05 QALYs. The ICUR of genotype-guided therapy compared with clopidogrel was USD4,200. Genotype-guided therapy provided more QALYs at lower costs compared with prasugrel. Results were sensitive to the cost of clopidogrel and relative risk of myocardial infarction and stroke between CYP2C19 variant vs. non-variant. Net monetary benefit curves showed that genotype-guided therapy had at least 70% likelihood of being the most cost-effective alternative at a willingness-to-pay of USD100,000/QALY. In comparison with clopidogrel, prasugrel therapy was more cost

    Background There are sparse data on the performance of different types of drug-eluting stents (DES) in acute and real-life setting. Objective The aim of the study was to compare the safety and efficacy of first- versus second-generation DES in patients with acute coronary syndromes (ACS). Methods This all-comer registry enrolled consecutive patients diagnosed with ACS and treated with percutaneous coronary intervention with the implantation of first- or second-generation DES in one-year follow-up. The primary efficacy endpoint was defined as major adverse cardiac and cerebrovascular event (MACCE), a composite of all-cause death, nonfatal myocardial infarction, target-vessel revascularization and stroke. The primary safety outcome was definite stent thrombosis (ST) at one year. Results From the total of 1916 patients enrolled into the registry, 1328 patients were diagnosed with ACS. Of them, 426 were treated with first- and 902 with second-generation DES. There was no significant difference in the incidence of MACCE between two types of DES at one year. The rate of acute and subacute ST was higher in first- vs. second-generation DES (1.6% vs. 0.1%, p < 0.001, and 1.2% vs. 0.2%, p = 0.025, respectively), but there was no difference regarding late ST (0.7% vs. 0.2%, respectively, p = 0.18) and gastrointestinal bleeding (2.1% vs. 1.1%, p = 0.21). In Cox regression, first-generation DES was an independent predictor for cumulative ST (HR 3.29 [1.30-8.31], p = 0.01). Conclusions In an all-comer registry of ACS, the one-year rate of MACCE was comparable in groups treated with first- and second-generation DES. The use of first-generation DES was associated with higher rates of acute and subacute ST and was an independent predictor of cumulative ST. PMID:27058257

  19. Risk stratification in non-ST elevation acute coronary syndromes: Risk scores, biomarkers and clinical judgment

    David Corcoran

    2015-09-01

    Clinical guidelines recommend an early invasive strategy in higher risk NSTE-ACS. The Global Registry of Acute Coronary Events (GRACE risk score is a validated risk stratification tool which has incremental prognostic value for risk stratification compared with clinical assessment or troponin testing alone. In emergency medicine, there has been a limited adoption of the GRACE score in some countries (e.g. United Kingdom, in part related to a delay in obtaining timely blood biochemistry results. Age makes an exponential contribution to the GRACE score, and on an individual patient basis, the risk of younger patients with a flow-limiting culprit coronary artery lesion may be underestimated. The future incorporation of novel cardiac biomarkers into this diagnostic pathway may allow for earlier treatment stratification. The cost-effectiveness of the new diagnostic pathways based on high-sensitivity troponin and copeptin must also be established. Finally, diagnostic tests and risk scores may optimize patient care but they cannot replace patient-focused good clinical judgment.

  20. Clinical criteria replenish high-sensitive troponin and inflammatory markers in the stratification of patients with suspected acute coronary syndrome.

    Barbara Elisabeth Stähli

    Full Text Available OBJECTIVES: In patients with suspected acute coronary syndrome (ACS, rapid triage is essential. The aim of this study was to establish a tool for risk prediction of 30-day cardiac events (CE on admission. 30-day cardiac events (CE were defined as early coronary revascularization, subsequent myocardial infarction, or cardiovascular death within 30 days. METHODS AND RESULTS: This single-centre, prospective cohort study included 377 consecutive patients presenting to the emergency department with suspected ACS and for whom troponin T measurements were requested on clinical grounds. Fifteen biomarkers were analyzed in the admission sample, and clinical parameters were assessed by the TIMI risk score for unstable angina/Non-ST myocardial infarction and the GRACE risk score. Sixty-nine (18% patients presented with and 308 (82% without ST-elevations, respectively. Coronary angiography was performed in 165 (44% patients with subsequent percutaneous coronary intervention--accounting for the majority of CE--in 123 (33% patients, respectively. Eleven out of 15 biomarkers were elevated in patients with CE compared to those without. High-sensitive troponin T (hs-cTnT was the best univariate biomarker to predict CE in Non-ST-elevation patients (AUC 0.80, but did not yield incremental information above clinical TIMI risk score (AUC 0.80 vs 0.82, p = 0.69. Equivalence testing of AUCs of risk models and non-inferiority testing demonstrated that the clinical TIMI risk score alone was non-inferior to its combination with hs-cTnT in predicting CE. CONCLUSIONS: In patients presenting without ST-elevations, identification of those prone to CE is best based on clinical assessment based on TIMI risk score criteria and hs-cTnT.

  1. [Role of anti-inflammatory drugs in the treatment of acute coronary syndromes. From athero-inflammation to athero-thrombosis].

    Altman, Raúl; Scazziota, Alejandra

    2003-01-01

    Coronary thrombosis is the most important cause of morbidity and mortality and the most severe manifestation of atherosclerosis. Knowledge of the pathophysiology of atheroma formation and the causes of atheroma accidents have allowed the development of new therapeutic measures for reducing thrombotic events after a coronary episode. Treating the thrombosis after plaque rupture is useful, but a late measure once coronary flow is disturbed. Therefore, treatment at an earlier stage, which we call athero-inflammation, a central event in atheroma progression leading to atherothrombosis, seems wise. There is evidence of an inflammatory component in the pathogenesis of atheroma rupture in acute coronary events. Earlier studies of anti-inflammatory medication have not demonstrated a reduction in thrombotic complications after an acute coronary episode. However, there are pathophysiological arguments and clinical findings that suggest that it would be advisable to include anti-inflammatory medications, especially those that inhibit preferentially COX-2, in the therapeutic arsenal for this pathology. We postulated that blocking athero-inflammation could prevent thrombosis. A pilot study was carried out in 120 patients with acute coronary syndrome without ST-segment elevation in which 60 patients were treated with meloxicam, a preferential COX-2 inhibitor. All patients received heparin and aspirin. During the stay in the coronary care unit, as well as after 90 days, meloxicam lowered composite outcomes (myocardial infarction, death and revascularization procedures) compared with the control group. These results and available pathophysiological and clinical evidence support the hypothesis of potential benefits of non-steroidal anti-inflammatory drugs with preferential inhibitory activity on COX-2 in patients with acute coronary syndromes. More trials are needed to confirm their preventive effect. PMID:12549993

    Patient registries that document real-world clinical experience play an important role in cardiology as they complement the data from randomized controlled trials, provide valuable information on drug use and clinical outcomes, and evaluate to what extent guidelines are followed in practice. The Platelet Inhibition Registry in ACS EvalUation Study (PIRAEUS) project is an initiative of registry holders who are managing national or international registries observing patients with acute coronary syndromes (ACS). The aim of PIRAEUS is to systematically compare and combine available information/insights from various European ACS registries with a focus on P2Y12 inhibitors. The present publication introduces the 17 participating registries in a narrative and tabular form, and describes which ACS groups and which dual antiplatelet therapies were investigated. It sets the basis for upcoming publications that will focus on effectiveness and safety of the antiplatelets used. PMID:27532447

    2016-05-01

    Acute coronary syndrome (ACS), especially myocardial infarction, commonly known as a heart attack, is a serious life-threatening cardiovascular disease. Despite dramatic therapeutic advances, there have still been more than 20% patients with ACS suffering recurrent adverse cardiovascular events 3 years after disease onset. Therefore, the aim to prevent cardiac death caused by the heart attack remains challenging. Plasma biomarkers, originally developed to complement clinical assessment and electrocardiographic examination for the diagnosis of ACS, have been reported to play important prognostic roles in predicting adverse outcomes. These biomarkers mirror different pathophysiological mechanisms in association with ACS. In this review, we focus on advances of prognostic biomarkers in the past decade for short- and long-term risk assessment and management of patients with ACS. PMID:27089223

  5. New Approaches to the Role of Thrombin in Acute Coronary Syndromes: Quo Vadis Bivalirudin, a Direct Thrombin Inhibitor?

    María Asunción Esteve-Pastor

    2016-02-01

    Full Text Available The pathophysiology of acute coronary syndrome (ACS involves platelet activation and thrombus formation after the rupture of atherosclerotic plaques. Thrombin is generated at the blood-plaque interface in association with cellular membranes on cells and platelets. Thrombin also amplifies the response to the tissue injury, coagulation and platelet response, so the treatment of ACS is based on the combined use of both antiplatelet (such as aspirin, clopidogrel, prasugrel and ticagrelor and antithrombotic drugs (unfractionated heparin, enoxaparin, fondaparinux and bivalirudin. Bivalirudin competitively inhibits thrombin with high affinity, a predictable response from its linear pharmacokinetics and short action. However, a present remarkable controversy exists between the latest main Guidelines in Clinical Practice and the key trials evaluating the use of bivalirudin in ACS. The aim of this review is to update the development of bivalirudin, including pharmacological properties, obtained information from clinical trials evaluating efficacy and safety of bivalirudin in ACS; as well as the recommendations of clinical Guidelines.

  7. Assessment of Takotsubo (ampulla) cardiomyopathy using 99mTc-tetrofosmin myocardial SPECT. Comparison with acute coronary syndrome

    We assessed Takotsubo (ampulla) cardiomyopathy compared with acute coronary syndrome (ACS) using two-dimensional echocardiography and 99mTc-tetrofosmin myocardial SPECT. We examined 10 patients with Takotsubo cardiomyopathy and 16 with ACS at the time of emergency admission (acute phase), at three to nine days after the attack (subacute phase) and at one month after the attack (chronic phase). The left ventricle was divided into nine regions on echocardiograms and SPECT images, and the degree of abnormalities in each region was scored in five grades from normal (0) to severely abnormal (4). Coronary angiography revealed total or subtotal occlusion in patients with ACS but no stenotic legions in those with Takotsubo cardiomyopathy. The amount of ST segment elevation (mm) was 7.9±3.4 in patients with Takotsubo cardiomyopathy and 7.3±3.7 in those with ACS (N.S.). Abnormal wall motion scores on echocardiograms were 13.8±4.4, 4.4±3.8 and 1.8±2.3 during the acute, subacute and chronic phases in patients with Takotsubo cardiomyopathy, and 13.9±4.0, 11.7±3.7, 7.6±4.2, respectively in patients with ACS. The value of MB fraction of creatine phosphokinase (IU/l) was 34±23 in patients with Takotsubo cardiomyopathy and 326±98 in those with ACS (p99mTc-tetrofosmin myocardial SPECT were 11.4±3.2, 3.2±3.3 and 0.7±1.1 during the acute, subacute and chronic phases respectively, in patients with Takotsubo cardiomyopathy, and 15.8±4.1, 13.5±4.4, 8.2±4.4, respectively, in those with ACS. The numbers of myocardial segments that did not uptake 99mTc-tetrofosmin during the acute phase were 0.5±0.8 and 3.6±2.8 in patients with Takotsubo cardiomyopathy and ACS, respectively. Impaired coronary microcirculation might be a causative mechanism of Takotsubo cardiomyopathy. (author)

Methods: Data from the Medicare Current Beneficiary Survey were analyzed. Patients with incident hospitalization for ACS without similar events during the 6 months prior were included. Outcomes evaluated included inpatient mortality, 30-day mortality and readmission, subsequent hospitalization events, and total direct health care costs. Sample population weights were applied, accounting for multistage sampling design to obtain nationally representative estimates for the US Medicare population. Results: Between March 1, 2002 and December 31, 2006, we identified 795 incident ACS patients (mean age 76 years; 49% male representing 2,542,211 Medicare beneficiaries. The inpatient mortality rate was 9.71% and the 30-day mortality ranged from 10.96% to 13.93%. The 30-day readmission rate for surviving patients was 18.56% for all causes and 17.90% for cardiovascular disease (CVD-related diagnoses. The incidence of death since admission was 309 cases per 1000 person–years. Among patients discharged alive, the incidence was 197 for death, 847 for CVD-related admission, and 906 for all-cause admission. During the year when the ACS event occurred, mean annual total direct health care costs per person were US$50,458, with more than half attributable to inpatient hospitalization ($27,609. Conclusion: In this national representative Medicare population, we found a substantial clinical and economic burden for ACS. These findings suggest a continuing unmet medical need for more effective management of patients with ACS. The continuous burden underscores the importance of development of new interventions and/or strategies to

In this context, the main risk factor in elderly patients, ie, frailty syndrome, gains special importance. The availability of tools to identify frail people is relevant for both research and clinical purposes. The purpose of this study was to investigate the correlation of a scale for assessing frailty – the Tilburg Frailty Indicator (TFI and its domains (mental and physical – with other research tools commonly used for comprehensive geriatric assessment in patients with ACS.Patients and methods: The study covered 135 people and was carried out in the cardiology ward at T Marciniak Lower Silesian Specialist Hospital in Wroclaw, Poland. The patients were admitted with ACS. ST segment elevation myocardial infarction and non-ST segment elevation myocardial infarction were defined by the presence of certain conditions in reference to the literature. The Polish adaptation of the TFI was used for the frailty syndrome assessment, which was compared to other single measures used in geriatric assessment: the Mini-Mental State Examination (MMSE, the Hospital Anxiety and Depression Scale (HADS, and Katz Index of Independence in Activities of Daily Living (ADLs.Results: The mean TFI value in the studied group amounted to 7.13±2.81 (median: 7, interquartile range: 5–9, range [0, 14]. Significant correlations were demonstrated between the values of the TFI and other scales: positive for HADS (r=0.602, P<0.001 and the reverse for MMSE (r=-0.603, P<0.001 and IADL (r=-0.462, P<0.001. Patients with a TFI score ≥5 revealed considerably higher values on HADS (P<0.001 and considerably lower values on the MMSE

    Although Helicobacter pylori (Hp) primarily colonizes gastric mucosa, it can occasionally inhabit in atherosclerotic plaques. Both forms of Hp infection may be involved in the pathogenesis of atherosclerosis via activation of a systemic or local inflammatory host reaction and induction of plaque progression and/or instability, possibly leading to coronary syndromes. The association between Hp infection and cardiovascular endpoint prevalence remains uncertain; however, it has been reported in many epidemiological investigations and may be reasonably explained by pathophysiological mechanisms. Besides the inflammatory pathway, Hp infection may trigger acute coronary syndromes by enhanced platelet reactivity and increased risk of gastrointestinal bleeding (type 2 myocardial infarction). The former seems to be predominantly related to the stimulatory effect of Hp infection on von Willebrand factor-binding and P-selectin activation, and the latter results from cytotoxic bacteria properties and aggravation of digestive tract injury related to aspirin or dual antiplatelet therapy. Despite these premises, the role of Hp infection in cardiovascular syndromes should still be recognized as controversial and requiring randomized, controlled trials to evaluate the outcome of Hp eradication in both cardiac and gastroenterological endpoints. Such need is also justified by potential bias of previous studies resulting from (1) using different diagnostic methods for identification of Hp infection, since only a small number of studies required confirmation of active Hp infection; and from (2) common lack of adjustment for important confounders such as socioeconomic status, smoking and effectiveness of eradication therapy, as well as the genetic characteristics of both the host and the bacterium.

    Full Text Available Eitan Abergel, Eugenia NikolskyHeart Institute, Rambam Health Care Campus and Technion-Israel Institute of Technology, Haifa, IsraelAbstract: Acute coronary syndromes (ACS are the leading cause of mortality and one of the main reasons for hospital admissions in the developed nations. Due to high rates of mortality and reinfarction, ACS represent a major public health concern. Platelets play a central role in atherothrombosis, the main pathologic substrate in ACS. Sufficient inhibition of platelet aggregation is therefore one of the key targets in the treatment of ACS. Blockade of the P2Y12 subtype of adenosine diphosphate (ADP receptor on platelet cell membranes has been established as a key mechanism of platelet inhibition. Clopidogrel, an ADP receptor antagonist and a second-generation thienopyridine, has been demonstrated to be of clinical benefit in patients with ACS when added to aspirin. A delayed onset of action due to two-step conversion to the active metabolite, irreversible binding to P2Y12 receptors, and broad interindividual variability in levels of platelet response are the main limitations of clopidogrel. Prasugrel, a novel third-generation thienopyridine, provides faster and stronger inhibition of platelet aggregation than clopigodrel. However, like the active metabolite of clopidogrel, prasugrel binds irreversibly to the P2Y12 ADP receptor site, causing inhibition of platelet aggregation for the life of the platelet. Although in a randomized, double-blind trial prasugrel demonstrated superiority for multiple cardiovascular endpoints compared with standard-dose clopidogrel, it was also associated with an increased bleeding risk, including fatal bleeding. This review discusses the optimal antiplatelet regimens for management of patients with ACS, with special focus on ticagrelor, the first oral agent in a new chemical class of nonthienopyridine antiplatelet agents termed cyclopentyl-triazolo-pyrimidines.

    Contrast-induced nephropathy (CIN) is one of the major causes of hospital-acquired acute renal failure. The pathophysiological mechanism of CIN remains unknown. There has been little evidence regarding the effects of Traditional Chinese Medicine (TCM) on CIN. Cordyceps sinensis (CS), a traditional Chinese herb, has been widely used clinically for the prevention of the progression of renal failure. We performed a prospective, randomized controlled trial to investigate the role of CS in the prevention of CIN in patients with acute coronary syndrome (ACS) undergoing elective percutaneous coronary intervention (PCI). The 150 ACS patients were randomly assigned to three groups, basic treatment group (n=51), standard CS therapy group (n=49, corbrin capsule 2 g, 3 times/d were used 3 days before and after angiography), and intensive CS therapy group (n=50, corbrin capsule 3 g, 3 times/d were used 3 days before and after angiography). Renal function was assessed at the time of hospital admission and on days 1, 2, and 3 after PCI. CIN occurred in 13 of 150 patients (8.67%). The incidence of CIN was lower in the CS treatment groups than in the basic treatment group (P<0.05), and a significant decrease in the incidence of CIN in the intensive CS therapy group was shown (P<0.01). In conclusion, prophylactic treatment with CS during the peri-procedural stage in ACS patients undergoing elective PCI has a preventive role against CIN, and intensive CS therapy could be more effective.

    Full Text Available Abstract Background Genome-wide association studies (GWAS have identified new candidate genes for the occurrence of acute coronary syndrome (ACS, but possible effects of such genes on survival following ACS have yet to be investigated. Methods We examined 95 polymorphisms in 69 distinct gene regions identified in a GWAS for premature myocardial infarction for their association with post-ACS mortality among 811 whites recruited from university-affiliated hospitals in Kansas City, Missouri. We then sought replication of a positive genetic association in a large, racially diverse cohort of myocardial infarction patients (N = 2284 using Kaplan-Meier survival analyses and Cox regression to adjust for relevant covariates. Finally, we investigated the apparent association further in 6086 additional coronary artery disease patients. Results After Cox adjustment for other ACS risk factors, of 95 SNPs tested in 811 whites only the association with the rs6922269 in MTHFD1L was statistically significant, with a 2.6-fold mortality hazard (P = 0.007. The recessive A/A genotype was of borderline significance in an age- and race-adjusted analysis of the entire combined cohort (N = 3095; P = 0.052, but this finding was not confirmed in independent cohorts (N = 6086. Conclusions We found no support for the hypothesis that the GWAS-identified variants in this study substantially alter the probability of post-ACS survival. Large-scale, collaborative, genome-wide studies may be required in order to detect genetic variants that are robustly associated with survival in patients with coronary artery disease.

    Full Text Available Introduction. Rupture of vulnerable atherosclerotic plaques is the cause of most acute coronary syndromes (ACS. Postmortem studies which compared stable coronary lesions and atherosclerotic plaques in patients who have died because of ACS indicated high lipid-core content as one of the major determinants of plaque vulnerability. Objective. Our primary goal was to assess the potential relations of plaque composition determined by IVUS-VH (Intravascular Ultrasound - Virtual Histology in patients with stable angina and subjects in acute phase of ACS without ST segment elevation. Methods. The study comprised of 40 patients who underwent preintervention IVUS examination. Tissue maps were reconstructed from radio frequency data using IVUS-VH software. Results. We analyzed 53 lesions in 40 patients. Stable angina was diagnosed in 24 patients (29 lesions, while acute phase of ACS without ST elevation was diagnosed in 16 patients (24 lesions. In the patients in acute phase of ACS without ST segment elevation IVUS-VH examination showed a significantly larger area of the necrotic core at the site of minimal lumen area and a larger mean of the necrotic core volume in the entire lesion comparing to stable angina subjects (1.84±0.90 mm2 vs. 0.96±0.69 mm2; p<0.001 and 20.94±15.79 mm3 vs. 11.54±14.15 mm3; p<0.05 respectively. Conclusion. IVUS-VH detected that the necrotic core was significantly larger in atherosclerotic lesions in patients in acute phase of ACS without ST elevation comparing to the stable angina subjects and that it could be considered as a marker of plaque vulnerability.

  17. Combination of Fibrinogen and High-sensitivity C-reactive Protein Measurements is Potential in Identification of Acute Coronary Syndrome

    Djanggan Sargowo

    2015-04-01

    Full Text Available BACKGROUND: Acute myocardial infarction (AMI is one of cardiovascular diseases with high morbidity and mortality rates. Novel biomarkers that can detect accurately acute coronary syndrome (ACS at early stage, are necessary to improve current strategies and/or to identify subjects who are at risk. Fibrinogen and high-sensitivity C-reactive protein (hs-CRP roles in inflammation process could be potential for ACS early detection. This study was conducted to evaluate measurements of fibrinogen and hs-CRP on ACS. METHODS: An analytic observational study with cross sectional approach was conducted on patients with Troponin I positive. After signing informed consent, anamnesis and complete blood count were conducted. Besides that, liver function, renal function, and blood glucose tests were conducted as well. Samples of selected subjects were quantified with enzyme-linked immunosorbent assay (ELISA for Troponin I, fibrinogen and hs-CRP. Then statistical analyses were performed. RESULTS: There were 76 subjects in each ACS and non-ACS groups. ACS group showed significant higher levels of both fibrinogen and hs-CRP compared to Non-ACS group (p=0.000. Among evaluated risk factors, diabetes mellitus (DM (p=0.003 and hypertension (p=0.000 were significantly higher in ACS group than in non-ACS group. Among evaluated clinical factors, blood glucose (p=0.001 and age (p=0.000 were significantly higher in ACS group than in non-ACS group. Combination of fibrinogen and hs-CRP measurements showed the highest sensitivity (75.00%, specificity (80.26%, accuracy (77.63%, positive predictive value (79.19% and negative predictive value (76.25%. CONCLUSIONS: Since fibrinogen and hs-CRP were increased in ACS group and combination of fibrinogen and hs-CRP measurements showed the highest sensitivity, specificity, accuracy, positive predictive value and negative predictive value, we suggest that combination of fibrinogen and hs-CRP measurements could give added value to

    Full Text Available Objective: to identify the most prognostically significant scale risk assessment of patients with acute coronary syndrome without ST-segment elevation in combination with diabetes mellitus type 2, chronic renal failure, multifo-cal coronarocardiosclerosis, dyscirculatory encephalopathy. Material and methods. 260 patients with acute coronary syndrome without ST-segment elevation were divided into 4 groups according to the presence of severe concomitant diseases: patients with diabetes mellitus type 2 (71 people, chronic renal failure (49, multifocal lesions of the coronary arteries (76 and patients with dyscirculatory encephalopathy of grade 2-3, including ischemic stroke (64. All patients were stratified by major scales risk: TIMI, GRACE, PURSUIT. The development of negative coronary events was assessed in hospital and during the year after discharge. On the basis of the results, all scales were studied using the criterion of Mann-Whitney and identified the most predictably significant groups of patients with specific comorbid conditions. Results. It is revealed that the significance of the scales TIMI and GRACE in the study of distant forecast (up to 6 months is the most reliable with acute coronary syndrome without ST-segment elevation in combination with diabetes mellitus type 2. For the patients with combination with chronic renal insufficiency the best prognostic significance was obtained by the GRACE scale in the study of hospital risk and forecast up to 6 months. TIMI and GRACE scales in the study of hospital risk and forecast up to 6 months had the greatest prognostic significance for the patients with acute coronary syndrome without ST-segment elevation on the background of multifocal lesions of the coronary arteries. For the patients with dyscirculatory encephalopathy of the 2nd and 3rd grades, the greatest prognostic significance was obtained by stratification of risk on PURSUIT and GRACE scales in the study of hospital risk and

  19. An evaluation of short and long-term outcomes of TAXUS stent in patient with acute coronary syndrome

    Objective: To investigate the effect and security of TAXUS stent (paclitaxel-eluting stent) in patients with acute coronary syndrome (ACS). Methods: From November 2002 to December 2004, 94 patients with ACS had 120 TAXUS stents placed. Twenty -seven out of 95 had ST- segment elevation myocardial infarction; 8 had non- ST-segment elevation myocardial infarction and 59 had unstable angina. As for lesion characteristics, diffuse disease was found in 19 case, bifurcation lesions in 21 cases, chronic severe occlusion lesions in 19 cases, in-stent restenosis in 5 cases and ostial lesions in 6 case. The immediate angiographic outcome, six mouth follow-up results with major cardiac evrdiac event (MACE) and follow-up angiography in 6-7th mouth had been assessed. Results: Successful stent- placing procedure was achieved in 99% patients with ACS. Sub- acute stent thrombosis occurred in 1 patient, late stent thrombosis leading to AMI occurred in 1 patient. There was no death during the procedure and 6 -month follow -up. The MACE rate during hospitalization was 0.0% and was 7.4% during 6 month follow -up. Follow -up study performed in 6-7th month showed that restenosis rate (ISR) was 13.0% (in-stent restenosis rate was 2.7%). And the target vessel revascularization (TLR) rate was 2.7%. Conclusion: TAXUS stent implantation in the treatment of ACS is safe and effective, providing a significantly lower ISR rate than the convetional metal stents. (authors)

  20. Study on plasma C-reactive protein and IL-6 levels in patients with acute coronary syndrome

    Objective: To explore the difference between the plasma C-reactive protein (CRP) and serum interleukin 6(IL-6) levels of patients with acute coronary syndrome (ACS) and patients with stable angina pectoris (SAP). Methods: Plasma CRP (with immunoturbidometry) and serum IL-6 (with RIA) levels were determined in the following subjects: 1) 57 patients with ACS including 21 with acute myocardial infarction (AMI) and 36 with unstable angina pectoris (UAP; Braunwald grade I 11, grade II 10, grade III 15), 2) 48 patients with stable angina pectoris (SAP) as controls. Results: Plasma levels of CRP and serum level IL-6 in patients with AMI and patients with UAP were significantly higher than those in the controls (P0.05). Plasma CRP levels were correlated positively to IL-6 in all these three groups (rAMI=0.569, rUAP=0.413, rSAP=0.475, P<0.01, P<0.05). Conclusion: Plasma levels of CRP and IL-6 were higher in patients with ACS, indicating the important role played by inflammation in the pathogenesis. (authors)

  15. Laser blood irradiation effect on electrophysiological characteristics of acute coronary syndrome patients

    Khotiaintsev, Sergei N.; Doger-Guerrero, E.; Glebova, L.; Svirid, V.; Sirenko, Yuri

    1996-11-01

    This paper treats electro-physiological effects of the low- level laser irradiation of blood (LBI). The data presented here are based on the observation of almost 200 patients suffering from the acute disruption of coronary blood circulation, unstable angina pectoris and myocardial infarction. Statistically significant changes of the electro-physiological characteristics were observed in the group of 65 patients, treated by the LBI. In particular, the significant 6 percent extension of the effective refractory period was observed. The electrical situation threshold has increased by 20.6 percent. The significant changes of some other important electro-physiological characteristics were within the range of 5-15 percent. In this paper, the data obtained on the LBI effectiveness are compared also with the results obtained on 94 patients who in addition to the standard anti-angina therapy were treated by the autohaemo- transfusion performed simultaneously with the UV-light irradiation of the transfused blood. The results obtained demonstrate the significant positive effect of the low energy LBI. The electrophysiological data obtained have good correlation with observed anti-arrhythmic effect of the LBI. This is proved by the data obtained on the electro- physiological characteristics of the cardiovascular system and by other clinical data on the experimental and control group of patients. In the course of this research the exact effect of the low level LBI was established. LBI led to the pronounced positive changes in electro-physiological characteristics of the cardiovascular system of the patients, it also led to the pronounced anti-arrhythmic effect.

    Zheng-Feng Zhu

    Full Text Available OBJECTIVE: CD4(+ latency-associated peptide (LAP(+ regulatory T cells (Tregs are a newly discovered T cell subset in humans and the role of these cells in patients with acute coronary syndrome (ACS has not been explored. We designed to investigate whether circulating frequency and function of CD4(+LAP(+ Tregs are defective in ACS. METHODS: One hundred eleven ACS patients (acute myocardial infarction and unstable angina and 117 control patients were enrolled in the study. The control patients consisted of chronic stable angina (CSA and chest pain syndrome (CPS. The frequencies of circulating CD4(+LAP(+ Tregs and the expression of the transmembrane protein glycoprotein-A repetitions predominant (GARP on CD4(+ T cells were determined by flow cytometry. The function of CD4(+LAP(+ Tregs was detected using thymidine uptake. Serum interleukin-10 (IL-10 and transforming growth factor-β protein (TGF-β levels were detected using ELISA and expression of GARP mRNA in peripheral blood mononuclear cells (PBMCs was measured by real time-polymerase chain reaction. RESULTS: We found ACS patients had a significantly lower frequency of circulating CD4(+LAP(+ Tregs, and the function of these cells was reduced compared to controls. The expression of GARP in CD4(+ T cells and the serum levels of TGF-β in ACS patients were lower than those of control patients. The serum levels of IL-10 were similar between the two cohorts. CONCLUSIONS: A novel regulatory T cell subset, defined as CD4(+LAP(+ T cells is defective in ACS patients.

    Background The aims of this study were to analyze the dynamics of quality of life (QoL) changes after 36 months from the percutaneous coronary intervention (PCI) depending on sex and identify baseline predictors of the follow-up QoL of patients hospitalized for acute coronary syndrome (ACS) and subjected to PCI. Methods and results The study included 137 patients, females (n=67) and males (n=70), with ACS who underwent PCI. The QoL was assessed using the MacNew Heart Disease Health-Related Quality of Life questionnaire. The group of females scored lower in all the domains of the MacNew Heart Disease Health-Related Quality of Life questionnaire in the initial measurement (B1), in the measurement after 6 months (B2), and in the long-term follow-up measurement (36 months – B3). Despite the fact that both groups achieved improved QoL, its values were higher in the males. The average growth rate of the QoL score in the period from the sixth month to 36th month was higher in females than in males. In the univariate and multivariate analyses, significant independent predictors with a negative influence on the long-term QoL score included female sex (ρ=−0.190, β=−0.21), age >60 years (ρ=−0.255, β=−0.186), and diabetes (ρ=−0.216, β=−0.216). Conclusion In a 36-month follow-up of ACS patients treated with PCI, there were no statistically significant differences in QoL between sexes. In the entire cohort, there was improvement in QoL, which was higher in the case of the females studied. For the entire group, significant independent determinants of lower QoL 3 years after ACS included female sex, age >60 years, and diabetes. PMID:27499616

    2016-01-01

    Background and Objectives There is controversy surrounding whether or not high dose statin administration before percutaneous coronary intervention (PCI) decreases peri-procedural microvascular injury. We performed a prospective randomized study to investigate the mechanisms and effects of pre-treatment high dose atorvastatin on myocardial damage in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) undergoing PCI. Subjects and Methods Seventy seven patients with NSTE-ACS were randomly assigned to either the high dose group (atorvastatin 80 mg loading 12 to 24 h before PCI with a further 40 mg loading 2 h before PCI, n=39) or low dose group (atorvastatin 10 mg administration 12 to 24 h before PCI, n=38). Index of microcirculatory resistance (IMR) was measured after stent implantation. Creatine kinase-myocardial band (CK-MB) and high sensitivity C-reactive protein (CRP) levels were measured before and after PCI. Results The baseline characteristics were not different between the two patient groups. Compared to the low dose group, the high dose group had lower post PCI IMR (14.1±5.0 vs. 19.2±9.3 U, p=0.003). Post PCI CK-MB was also lower in the high dose group (median: 1.40 ng/mL (interquartile range [IQR: 0.75 to 3.45] vs. 4.00 [IQR: 1.70 to 7.37], p=0.002) as was the post-PCI CRP level (0.09 mg/dL [IQR: 0.04 to 0.16] vs. 0.22 [IQR: 0.08 to 0.60], p=0.001). Conclusion Pre-treatment with high dose atorvastatin reduces peri-PCI microvascular dysfunction verified by post-PCI IMR and exerts an immediate anti-inflammatory effect in patients with NSTE-ACS.

  20. Psychological stress and 30-day all-cause hospital readmission in acute coronary syndrome patients: an observational cohort study.

    Donald Edmondson

    Full Text Available BACKGROUND: Many acute coronary syndrome (ACS; myocardial infarction and unstable angina patients are rehospitalized within 30 days of discharge, and recent US health policy initiatives have tied hospital Medicare reimbursement to 30-day readmission rates. Patient-perceived psychological stress is thought to impact prognosis after ACS. A recently offered "posthospital syndrome" model of 30-day readmissions posits that the stress level at the time of the index hospitalization itself may increase 30-day risk for readmission in ACS patients. We tested whether self-reported stress in the days surrounding the ACS hospitalization was associated with increased risk for readmission within 30 days. METHODS: A mean of 8.5 days after discharge, 342 consecutively hospitalized ACS patients reported on how often they felt stress during the past two weeks. Readmission within 30 days of hospital discharge for any cause was determined by follow-up telephone calls to patients and confirmed by hospital records. RESULTS: Overall, 40 (11.7% participants were readmitted within 30 days, and 22 (6.4% reported high stress. Readmission within 30 days was more common in patients with high stress (5 admissions, 23% than in patients with low stress (35 admissions, 11%. After adjustment for demographic and clinical factors, as well as depression, high stress was associated with a 3-fold increased risk of 30-day readmission (HR = 3.21, 95% CI = 1.13, 9.10. CONCLUSIONS: Previous research has shown that stress in the days surrounding a hospitalization can mark long-term cardiovascular risk, but this is the first study to test a hypothesis of the posthospital syndrome model of early readmission. Further research is needed to confirm the association between stress and readmission risk, and to identify the processes of hospitalization that could be modified to both reduce the stress experienced and that would also be effective for reducing readmissions.

  1. Relationship of High Sensitivity C-Reactive Protein with Cardiac Biomarkers in Patients Presenting with Acute Coronary Syndrome

    Objective: To determine high sensitivity C-reactive protein (hsCRP) levels in patients with acute myocardial infarction (AMI) and its correlation with classical enzyme markers of myocardial damage. Study Design: Observational study. Place and Duration of Study: Department of Emergency Medicine at King Khalid University Hospital, King Saud University, Riyadh and Department of Physiology, from August 2010 to December 2011. Methodology: Consecutive eligible patients with either ST elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI) who were admitted to the Emergency Department of King Khalid University Hospital were recruited. A total of 71 subjects were finally selected for the study. The hsCRP, Troponin I (Trop I), creatine kinase myocardial bound (CK-MB), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) concentrations of all patients with an acute myocardial infarction (AMI) were measured. Results: Among all patients 34 (47.9%) patients had diabetes mellitus, 21 (29.6%) were hypertensive, and 16 (22.5%) had no associated illness. Patients with STEMI had significantly higher levels of CKMB (p=0.0348), LDH (p=0.0471) and hsCRP (p=0.0231) compared to NSTEMI patients. While the differences were non-significant for Trop I (p=0.7022), AST (p=0.9729) and Lp(a) (p=0.5985). Spearman's correlations revealed that CRP correlated significantly with Trop I, CK-MB and LDH. There was a significant predictive relationship of hsCRP with Trop I, LDH and CK-MB while with AST it was nonsignificant. Conclusion: High sensitivity CRP levels is a significant predictor of standard markers for myocardial damage and it may be a useful prognostic marker in acute coronary syndromes. (author)

Background: Patients with ACS are at risk for both cardiac autonomic dysfunction and clinical depression. Both conditions can negatively impact the ability to recover from an acute physiological insult, such as unstable angina or myocardial infarction, increasing the risk for adverse cardiovascular outcomes. HRV is recognized as a reflection of autonomic function. Methods: A narrative review was undertaken to evaluate state-of-the-art clinical research, using the PubMed database, January 2013. The search terms “heart rate variability” and “depression” were used in conjunction with “acute coronary syndrome”, “unstable angina”, or “myocardial infarction” to find clinical studies published within the past 10 years related to HRV and clinical depression, in patients with an ACS episode. Studies were included if HRV measurement and depression screening were undertaken during an ACS hospitalization or within 2 months of hospital discharge. Results: Nine clinical studies met the inclusion criteria. The

    Polymorphisms of CYP2C19 are associated with platelet response to clopidogrel. This study was conducted to evaluate the contribution of the previously identified polymorphisms to the response of clopidogrel in a cohort of Chinese Han patients. Atotal of 222 acute coronary syndrome patients undergoing percutaneous coronary intervention treated with clopidogrel were enrolled from September 2012 to June 2013. Residual platelet aggregations for all patients were measured by the Verify Now P2Y12 system. Sixteen single-nucleotide polymorphisms among nine genes were genotyped including CYP2C19, ABCB1 and PON1. In this study, CYP2C19*2 and CYP2C19*17 were strongly associated with higher platelet aggregation and lower platelet aggregation to clopidogrel treatment, respectively (P ≯0.001). Patients with CYP2C19*2 allele had a higher risk of high on-treatment platelet reactivity than non carriers (adjusted OR, 5.434; 95% CI, 1.918–15.399, P=0.01). The coexistenceof CYP2B6*9 (rs8192719) and P2Y12 (rs2046934) and the coexistence of CYP2B6*1B (rs7254579) and P2Y12 (rs2046934) were also associated with poor response to clopidogrel. No significant relation of CYP2C19*3 and other polymorphisms to the platelet aggregation was found. In conclusion, CYP2C19*2, CYP2C19*17 coexistence of CYP2B6*9 (rs8192719) and P2Y12 (rs2046934) and coexistence of CYP2B6*1B (rs7254579) and P2Y12 (rs2046934) were identified to be associated with response to clopidogrel treatment in Chinese Han patients.

    Full Text Available Background: Cardiovascular disease is the leading cause of mortality. The previous findings which suggest the reduction in C-reactive protein (CRP levels by statin encouraged us to conduct the present study in which we tested the effects of atorvastatin, on levels of hs-CRP in a prospective randomised clinical trial study on patients with acute coronary syndrome. Materials and Methods: Present prospective randomised clinical trial study conducted on 180 patients who had developed coronary artery disease and presented in emergency departments of Educational-Medical centers of Tabriz University of Medical Sciences. The patients were divided randomly into two groups and then two therapeutic protocols were given to them. One group medicated by high-dose atorvastatin (40 mg and the other group received low-dose atorvastatin (20 mg. All variables were collected by questionnaires and were analyzed. Results: There were 180 patients consisted of 34 females and 56 males in low-dose atorvastatin group (L-DA group, and 30 females and 60 males in high-dose atorvastatin group (H-DA group (P = 0.533. In this study atorvastatin in high doses decreased hs-CRP levels about 40% and in low doses it only caused decrease of 13.3%, and significant correlation was observed between two groups (Paired Sample T-test (P = 0.001. Also atorvastatin in high doses decreased LDL levels about 23% and in low doses it only decreased 10%, and significant correlation was observed between two groups (Paired Sample T-test( (P = 0.001. Atorvastatin in high doses decreased HDL levels about 9% and in low doses it only decreased 6%, and again significant correlation was observed between two groups (P = 0.009. Conclusion: The present study confirms the novel observation that atorvastatin therapy results in a significant reduction in hs-CRP levels.

  7. Platelet inhibitors in non-ST-segment elevation acute coronary syndromes and percutaneous coronary intervention: glycoprotein IIb/IIIa inhibitors, clopidogrel, or both?

    Silva, Matthew A; Donovan, Jennifer L; Gandhi, Pritesh J; Volturo, Gregory A

    2006-01-01

    The role of glycoprotein (Gp) IIb/IIIa receptor antagonists remains controversial and these agents are infrequently utilized during non-ST-segment elevation acute coronary syndromes (NSTE-ACS) despite American Heart Association/American College of Cardiology guidelines. Despite recommendations, the NRMI-4 (National Registry of Myocardial Infarction 4) and CRUSADE (Can rapid risk stratification of unstable angina patients suppress adverse outcomes with early implementation of the ACC/AHA guidelines?) registries observed that only 25%-32% of eligible patients received early Gp IIb/IIIa therapy, despite a 6.3% absolute mortality reduction in NRMI-4 and a 2% absolute mortality reduction in CRUSADE. A pooled analysis of Gp IIb/IIIa data from these registries suggest a major reduction in mortality (Odds Ratio = 0.43, 95% Confidence Index 0.25-0.74, p = 0.002) with early Gp IIb/IIIa therapy, yet clinicians fail to utilize this option in NSTE-ACS. The evidence-based approach to NSTE-ACS involves aspirin, clopidogrel, low-molecular weight heparins, or unfractionated heparin in concert with Gp IIb/Ila receptor antagonists, however, newer percutaneous coronary intervention (PCI)-based trials challenge current recommendations. Novel strategies emerging in NSTE-ACS include omitting Gp IIb/Ila inhibitors altogether or using Gp IIb/IIIa inhibitors with higher doses of clopidogrel in selected patients. The ISAR-REACT (Intracoronary stenting and antithrombotic regimen-Rapid early action for coronary treatment) and ISAR-SWEET (ISAR-Is abciximab a superior way to eliminate elevated thrombotic risk in diabetics) trials question the value of abciximab when 600 mg of clopidogrel concurrently administered during PCI. The CLEAR-PLATELETS (Clopidogrel loading with eptifibatide to arrest the reactivity of platelets) and PEACE (Platelet activity extinction in non-Q-wave MI with ASA, clopidogrel, and eptifibatide) trials suggest more durable platelet inhibition when Gp IIb/IIIa inhibitors are

    Full Text Available OBJECTIVE: To assess safety and efficacy of coronary angioplasty with stent implantation in unstable coronary syndromes. METHODS: Retrospective analysis of in-hospital and late evolution of 74 patients with unstable coronary syndromes (unstable angina or infarction without elevation of the ST segment undergoing coronary angioplasty with stent placement. These 74 patients were compared with 31 patients with stable coronary syndromes (stable angina or stable silent ischemia undergoing the same procedure. RESULTS: No death and no need for revascularization of the culprit artery occurred in the in-hospital phase. The incidences of acute non-Q-wave myocardial infarction were 1.4% and 3.2% (p=0.6 in the unstable and stable coronary syndrome groups, respectively. In the late follow-up (11.2±7.5 months, the incidences of these events combined were 5.7% in the unstable coronary syndrome group and 6.9% (p=0.8 in the stable coronary syndrome group. In the multivariate analysis, the only variable with a tendency to significance as an event predictor was diabetes mellitus (p=0.07; OR=5.2; 95% CI=0.9-29.9. CONCLUSION: The in-hospital and late evolutions of patients with unstable coronary syndrome undergoing angioplasty with intracoronary stent implantation are similar to those of the stable coronary syndrome group, suggesting that this procedure is safe and efficacious when performed in unstable coronary syndrome patients.

    Background Although the severity of inducible ischemia provides incremental prognostic information in persons with known or suspected coronary artery disease (CAD), its significance for predicting long-term CAD outcomes in apparently healthy populations is unknown. This study was designed to evaluate the presence and degree of myocardial ischemia in asymptomatic siblings of persons with premature CAD <60 years of age and to determine its significance for predicting incident acute coronary syndromes (ACS) during follow-up of 5 to 25 years. Methods Siblings (n = 1,287, age 30-59 years, 55% female) were screened for traditional risk factors, underwent exercise treadmill testing with nuclear perfusion imaging, and were followed for the development of ACS (mean follow-up 11.6 ± 5.1 years). The severity of ischemia was assessed by semiquantitative methods using the standard 17-segment model and then categorized by the percent maximal summed stress score as none (0%), minimal (1% to <5%), mild (5% to 10%), moderate (10% to 15%), or severe (≥15%). Results ACS occurred in 132 subjects (10.3%) and included sudden cardiac death (n = 13), acute MI (n = 62), and unstable angina with revascularization (n = 57). The presence of no (88%), minimal (6%), mild (5%), and moderate/severe (1%) ischemia was associated with an ACS incidence of 8.3%, 19.7%, 25.0%, and 38.9%, respectively (P < .0001 for trend). Kaplan-Meier event-free survival analyses by myocardial ischemia severity categories showed that even minimal and mild myocardial ischemia were associated with greater ACS incidence detectable as early as 2 years after baseline. A Cox proportional hazard model, adjusted for risk factors and follow-up time, showed that each 5% increment in the severity of ischemia resulted in a 77% increase in the hazard of incident ACS (P < .001). Conclusion Inducible myocardial ischemia is prevalent in asymptomatic siblings of persons with early onset CAD. Most ischemia is minimal or mild in

    Full Text Available Objective. To investigate the effect of acarbose therapy on the long-term prognosis of patients with acute coronary syndromes (ACS complicating newly diagnosed impaired glucose tolerance (IGT. Methodology. 135 patients hospitalized for ACS who had been newly diagnosed with IGT were randomly assigned to acarbose group (150 mg/day, n=67 or control group (no acarbose, n=68. All cases in each group were given the same elementary treatment. Mean follow-up was 2.3 years. The incidence of major adverse cardiovascular event (MACE and carotid intima-middle thickness (CIMT were statistically analyzed. Results. During the mean follow-up of 2.3 years, the risk of recurrent MACE in acarbose group was decreased significantly compared with that in control group (26.67% versus 46.88%, P<0.05; at the same time, thickening of the CIMT was significantly slower than the control group ((1.28 ± 0.42 mm versus (1.51 ± 0.64 mm, P<0.05. Conclusions. Acarbose can effectively reduce the risk of MACE in ACS patients with newly diagnosed IGT, simultaneously retarding the progression of carotid intima-media thickness.

    Background Several studies investigating the prognostic utility of interleukin-10 (IL-10) in patients with acute coronary syndrome (ACS) have provided conflicting findings.The aim of the study was to assess the existing evidence regarding association between serum IL-10 levels and adverse events.Methods Literature search was performed in PubMed,EMBASE,and Cochrane Trials Register databases from their inception to September 30,2012.In addition,reference lists of the included articles and their related citations in PubMed were also reviewed for additional pertinent studies.Results A total of 12 eligible studies comprising a total of 5882 patients were identified.The pooled relative risks for both studies reporting the risk estimates by IL-10 categories and studies reporting the risk estimates by unit IL-10 indicated an association between high IL-10 levels and adverse events.Sensitivity and subgroup analysis indicated that the results obtained in IL-10 categories were not stable.Conclusions Data from our meta-analysis supported the existence of a relationship between high serum IL-10 levels and adverse events in patients with ACS.Large study with longer follow-up is needed to confirm the findings.

  13. Comparison of enoxaparin and dalteparin with unfractionated heparin in the treatment of non-st elevated acute coronary syndrome

    The term non-ST elevated Acute Coronary Syndrome (ACS) encompasses unstable Angina (USA) and non-ST segment elevated Myocardial Infarction (NSTEMI), both of which may end up in death or a fatal/non-fatal Myocardial Infarction (MI). Unfractionated heparin (UFH) has been shown to reduce death and MI in patients with USA and NSTEMI. Of late, there has been a great interest in the role of low molecular weight heparins (LMWHs) in the two conditions and they have been found to be at least as effective as or even more effective than UFH. Methods: A total of 90 patients who presented to CCU of Khyber Teaching Hospital, Peshawar with USA or NSTEMI, from June 2008 to June 2009, were enrolled into the study. An equal number of patients were randomly assigned to one of the three arms for 5 days each: Group A received enoxaparin, group B received dalteparin and group C received UFH. The primary end points of the study were all cause mortality, STEMI, refractory USA, recurrent USA or a major bleed. The secondary end point was minor bleeding. Results: At the end of the study, there were 2 deaths each in the dalteparin and UFH group, whereas no such event was recorded in the enoxaparin group. Two patients had STEMI in the UFH group but none in the other two groups. (author)

    Full Text Available Abstract Background Previous studies suggested that genetic polymorphisms in the epidermal growth factor receptor (EGFR gene had been implicated in the susceptibility to some tumors and inflammatory diseases. EGFR has been recently implicated in vascular pathophysiological processes associated with excessive remodeling and atherosclerosis. Acute coronary syndrome (ACS is a clinical manifestation of preceding atherosclerosis. Our purpose was to investigate the association of the EGFR polymorphism with the risk of ACS. In this context, we analyzed the HER-1 R497K and EGFR intron 1 (CAn repeat polymorphisms in 191 patients with ACS and 210 age- and sex-matched controls in a Chinese population, using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP strategy and direct sequencing. Results There were significant differences in the genotype and allele distribution of R497K polymorphism of the EGFR gene between cases and controls. The Lys allele had a significantly increased risk of ACS compared with the Arg allele (adjusted OR = 1.49, 95% CI: 1.12–1.98, adjusted P = 0.006. However, no significant relationship between the number of (CAn repeats of EGFR intron 1 (both alleles P = 0.911. Considering these two polymorphisms together, there was no statistically significant difference between the two groups. Conclusion R497K polymorphism of the EGFR gene is significantly associated with the risk of ACS. Our data suggests that R497K polymorphism may be used as a genetic susceptibility marker of the ACS.

  15. Effect of fluvastatin on serum CRP, SLCAM-1 and SVCAM-1 contents in patients with acute coronary syndrome

    Objective: To study the effect of fluvastatin on changes of serum C-reactive protein (CRP) and soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1) contents in patients with acute coronary syndrome(ACS). Methods: 109 patients with ACS were randomly divided into fluvastatin-treated group(55 eases) and conventional therapy group (54 eases). The contents of serum CRP (with immunoturbidity method), sICAM-1, sVCAM-1 (with ELISA) were measured both before and after treatment for 8 weeks with fluvastatin in these cardiac patients as well as in 50 controls. Results: (1) Before treatment, the levels of serum CRP, sICAM-1, sVCAM-1 were significantly higher in the patients with ACS than controls (P<0.01). (2)After treatment,the levels of serum CRP, sICAM-1, sVCAM-1 in patients with fluvastatin decreased significantly(P <0.01), but the levels were not much changed in the conventional therapy group. Conclusion: Fluvastatin can decrease inflammation and cell adhesion in patients with ACS. (authors)

    Adherence to secondary prevention medications following acute coronary syndrome (ACS) is disappointingly low, standing around 40-75% by various estimates. This is an inefficient use of the resources devoted to their development and implementation, and also puts patients at higher risk of poor outcomes post-ACS. Numerous factors contribute to low adherence including poor motivation, forgetfulness, lack of education about medications, complicated polypharmacy of ACS regimens, (fear of) adverse side effects and limited practical support. Using technology to improve adherence in ACS is an emerging strategy and has the potential to address many of the above factors-computer-based education and mobile phone reminders are among the interventions trialled and appear to improve adherence in patients with ACS. As we move into an increasingly technological future, there is potential to use devices such as smartphones and tablets to encourage patient responsibility for medications. These handheld technologies have great scope for allowing patients to view online medical records, education modules and reminder systems, and although research specific to ACS is limited, they have shown initial promise in terms of uptake and improved adherence among similar patient populations. Given the overwhelming enthusiasm for handheld technologies, it would seem timely to further investigate their role in improving ACS medication adherence. PMID:25713726

    Background. Insulin resistance has been associated with dyslipidemia and cardiovascular disease. Even though homeostasis model assessment of insulin resistance (HOMA-IR) is a well-known insulin resistance predictor, estimation of serum lipoprotein ratios has been recently suggested as a surrogate marker for insulin resistance. Here, we evaluated the relationship between lipoprotein ratios and insulin resistance in normoglycemic nondiabetic south Indians with acute coronary syndrome. Methods. 100 normoglycemic nondiabetic ACS patients and 140 controls were enrolled in the study. Levels of fasting glucose, fasting insulin, and lipid profile [total cholesterol (TC), triglycerides (TG), and high density lipoprotein cholesterol (HDL-C)], lipoprotein(a) [Lp(a)] levels were measured and lipoprotein ratios were computed. HOMA-IR was used to calculate the insulin resistance. Receiver operating characteristic curves (ROC) analysis was used to compare the power of these lipoprotein ratios to predict insulin resistance. Results. Lipoprotein ratios were significantly higher in normoglycemic nondiabetic ACS patients, as compared to healthy controls, and were significantly correlated with HOMA-IR by Spearman's rank correlation analysis. ROC curve showed that Lp(a)/HDL-C and TG/HDL-C ratios were the best surrogate predictors of insulin resistance in normoglycemic nondiabetic ACS. Conclusion. This study demonstrates that serum lipoprotein ratios significantly correlate with insulin resistance in normoglycemic nondiabetic ACS. Lp(a)/HDL-C and TG/HDL-C ratios could be used as surrogate markers of insulin resistance in atherosclerosis-prone south Indians with normoglycemic nondiabetic ACS. PMID:24959351

    Objectives: To compare clinical characteristics, treatment, and utilization of evidence-based medicines at discharge from hospital in acute coronary syndrome (ACS) patients with or without diabetes at a tertiary care cardiac center in India. Methods: We performed an observational study in consecutive patients discharged following management of ACS. We obtained demographic details, comorbid conditions, and cardiovascular risk factors, physical and biochemical parameters, and management. Descriptive statistics are reported. Results: We enrolled 100 patients (diabetics = 28) with mean age of 59.0 ± 10.8 years (diabetics 59.3 ± 11.6, nondiabetics 58.9 ± 8.5). Forty-nine patients had ST-elevation myocardial infarction (STEMI) (diabetics = 14, 28.7%) while 51 had nonSTEMI/unstable angina (diabetics = 14, 27.4%) (P = nonsignificant). Among diabetics versus nondiabetics there was greater prevalence (%) of hypertension (78.6% vs. 44.4%), obesity (25.0% vs. 8.3%), abdominal obesity (85.7% vs. 69.4%) and sedentary activity (89.2% vs. 77.8%), and lower prevalence of smoking/tobacco use (10.7% vs. 25.0%) (P < 0.05). In STEMI patients 28 (57.1%) were thrombolysed (diabetes 17.8% vs. 31.9%), percutaneous coronary interventions (PCI) was in 67.8% diabetics versus 84.7% nondiabetics and coronary bypass surgery in 21.4% versus 8.3%. At discharge, in diabetics versus nondiabetics, there was similar use of angiotensin converting enzyme inhibitors (67.9% vs. 69.4%) and statins (100.0% vs. 98.6%) while use of dual antiplatelet therapy (85.7% vs. 95.8%) and beta-blockers (64.3% vs. 73.6%) was lower (P < 0.05). Conclusions: Diabetic patients with ACS have greater prevalence of cardiometabolic risk factors (obesity, abdominal obesity, and hypertension) as compared to nondiabetic patients. Less diabetic patients undergo PCIs and receive lesser dual anti-platelet therapy and beta-blockers.

    Objective To study the clinical role of the variation of serum matrix metalloproteinase-8 (MMP-8)concentration in patients with acute coronary syndrome (ACS). Methods ELISA method was adopted to detect serum MMP-8 concentration and to observe concentration's differences and features among 80 selected ACS cases (43 acute myocardial infarction and 37 unstable angina pectoris), 43 stable angina pectoris (SAP) cases and 37 control cases.And meanwhile the atherosclerosis risk factors of each case, such as age, sex, hypertension, body mass index, smoking,family history, diabetes, and hyperlipidemia were collected and analyzed as a whole. Results First, serum MMP-8 concentration reached the highest point in ACS, and there was significant difference between SAP and control groups (P0.05). Third, Logistic regression analysis revealed that serum MMP-8 concentration might be the indicator of ACS (B=4.493, P=0.000), particularly, that of AMI (B=9.961,P=0.000). Fourth, linear correlation and linear regression analysis found that only neutrophil was likely to influence serum MMP-8 concentration (r=0.274, P=0.001). Fifth, in the diagnosis of ACS, the area under ROC curve of MMP-8 was 0.785, the sensitivity and specificity were 68.6% and 76.5%, respectively. Conclusion ① Serum MMP-8 concentration has close relationship with the occurrence of ACS, particularly with AMI;② Serum MMP-8 concentration may be one of the predicting indicators of ACS and particularly of AMI;③ Neutrophil may be correlated with serum MMP-8 concentration;④ MMP-8 is of somewhat valuable in diagnosing ACS.

    In observational analyses, higher levels of high-density lipoprotein (HDL) cholesterol have been associated with a lower risk of coronary heart disease events. However, whether raising HDL cholesterol levels therapeutically reduces cardiovascular risk remains uncertain. Inhibition of cholesteryl...... ester transfer protein (CETP) raises HDL cholesterol levels and might therefore improve cardiovascular outcomes....

  3. Physical model of the haemodynamic effects around the obstructing plaque in the acute coronary syndromes take account of the stenosis geometry

    Selective coronary angiography with quantitative parameter assessment of the vessel stenosis geometry, which leads to acute coronary syndrome, was performed in 205 patients undergoing acute phase of myocardial infarction or unstable angina pectoris. Data for physicomechanical properties of the arterial vessels, blood and blood flow were used. The range of pressure variations accompanying the most frequently encountered ruptures of the atherosclerotic plaques was analyzed with physical model. It suggests that in 'lock' type plaques the ratio between the pressure on the wall of the normal vessel and that in the section outside the stenosis is considerably increased, especially in cases of enlarged vessel gauge. The results obtained show that the wall pressure closely to the plaque of a stenosed vessel with normal diameter of 3.5 mm exceeds 25 times the pressure within a normal vessel segment. (author)

    AIM:To investigate the contribution of anti-platelet therapy and derangements of pre-operative classical coagulation and thromboelastometry parameters to major bleeding post-coronary artery bypass grafting(CABG).METHODS:Two groups of CABG patients were studied:Group A,treated with aspirin alone(n=50),and Group B treated with aspirin and clopidogrel(n=50).Both had similar preoperative,clinical,biologic characteristics and operative management.Classic coagulation parameters and rotational thromboelastometry(ROTEM)profiles were determined preoperatively for both groups and the same heparin treatment was administered.ROTEM profiles(INTEM and EXTEM assays)were analyzed,both for traditional parameters,and thrombin generation potential,expressed by area-under-curve(AUC).RESULTS:There was no significant difference betweenrates of major bleeding between patients treated with aspirin alone,compared with those treated with aspirin and clopidogrel(12%vs 16%,P=0.77).In the 14 cases of major bleeding,pre-operative classic coagulation and traditional ROTEM parameters were comparable.Conversely we observed that the AUC in the EXTEM test was significantly lower in bleeders(5030±1115 Ohm*min)than non-bleeders(6568±548Ohm*min)(P<0.0001).CONCLUSION:We observed that patients with a low AUC value were at a significantly higher risk of bleeding compared to patients with higher AUC,regardless of antiplatelet treatment.This suggests that thrombin generation potential,irrespective of the degree of platelet inhibition,correlates with surgical bleeding.

    Background For patients with moderate to high-risk acute coronary syndromes(ACS)who undergo early,invasive treatment strategies,current guidelines recommend the usage of glycoprotein(GP)lib/Illa inhibitors as an upstream treatment for a coronary care unit or as an downstream provisional treatment for selected patients who are undergoing percutaneous coronary intervention(PCI).The relative advantage of either strategy is unknown.The purpose of this study was to evaluate the effects of upstream tirofiban versus the effects of downstream tirofiban on myocardial damage and 180-day major adverse cardiovascular events(MACE)after PCI in high-risk non-ST-segment elevation ACS (NSTE-ACS)undergoing PCI.Methods From July 2006 to July 2007,160 high-risk NSTE-ACS undergoing PCI were randomized to receive upstream (within 4-6 hours before coronary angiography)tirofiban or downstream(the guidewire crossing the lesion)tirofiban,to evaluate the extent of myocardial damage after PCI by quantitatively and qualitatively analyzing the value of cardiac troponin I(cTnl)as well as MB isoenzyme of creatine kinase(CK-MB)before and after PCI.The incidences of 24-hour,3-day,7-day,30-day and 180-day MACE after PCI were followed up and the rates of bleeding complications and thrombocytopenia during tirofiban administration were recorded.Results The peak release and cumulative release of cTnl levels within 48 hours after PCI were significantly lower with upstream tirefiban than downstream tirofiban(0.45 vs 0.63 and 0.32 vs 0.43,respectively;P<0.05).Post-procedural cTnl elevation within 48 hours was significantly less frequent among patients who received the upstream tirofiban than those who received the downstream tirefiban(66.3%vs 87.5%,P<0.05).The peak and cumulative release of CK-MB levels as well as post-procedural CK-MB elevation within 48 hours after PCI were not significantly different between the two groups (16 vs 14,5 vs 3 and 26.3%vs 36.3%,respectively;P>0.05).The incidences of

    Background The cardiovascular consequences of obstructive sleep apnoea (OSA) differ by sex. We hypothesized that sex influences the severity of acute coronary syndrome (ACS) in patients with OSA. OSA was defined as an apnoea–hypopnoea index (AHI)>15 events·h-1. We evaluated the severity of ACS according to the ejection fraction, Killip class, number of diseased vessels, number of stents implanted and plasma peak troponin level. Methods We included 663 men (mean±SD, AHI 37±18 events·h-1) and 133 women (AHI 35±18 events·h-1) with OSA. Results The men were younger than the women (59±11 versus 66±11 years, p<0.0001), exhibited a higher neck circumference (p<0.0001), and were more likely to be smokers and alcohol users than women (p<0.0001, p = 0.0005, respectively). Body mass index and percentage of hypertensive patients or diabetics were similar between sexes. We observed a slight tendency for a higher Killip classification in women, although it was not statistically significant (p = 0.055). For men, we observed that the number of diseased vessels and the number of stents implanted were higher (p = 0.02, p = 0.001, respectively), and a decrease in the ejection fraction (p = 0.002). Conclusions This study shows that sex in OSA influences the severity of ACS. Men show a lower ejection fraction and an increased number of diseased vessels and number of stents implanted.

    2016-01-01

    Introduction The ICON1 study (a study to Improve Cardiovascular Outcomes in high-risk older patieNts with acute coronary syndrome) is a prospective observational study of older patients (≥75 years old) with non-ST-elevation acute coronary syndrome managed by contemporary treatment (pharmacological and invasive). The aim of the study was to determine the predictors of poor cardiovascular outcomes in this age group and to generate a risk prediction tool. Methods and analysis Participants are recruited from 2 tertiary hospitals in the UK. Baseline evaluation includes frailty, comorbidity, cognition and quality-of-life measures, inflammatory status assessed by a biomarker panel, including microRNAs, senescence assessed by telomere length and telomerase activity, cardiovascular status assessed by arterial stiffness, endothelial function, carotid intima media thickness and left ventricular systolic and diastolic function, and coronary plaque assessed by virtual histology intravascular ultrasound and optical coherence tomography. The patients are followed-up at 30 days and at 1 year for primary outcome measures of death, myocardial infarction, stroke, unplanned revascularisation, bleeding and rehospitalisation. Ethics and dissemination The study has been approved by the regional ethics committee (REC 12/NE/016). Findings of the study will be presented in scientific sessions and will be published in peer-reviewed journals. Trial registration number NCT01933581: Pre-results. PMID:27554105

Background: Altered HRV has been associated with adverse outcomes in heart disease, but the value of HRV measured during the earliest phases of ACS related to risk of 1-year rehospitalization and death has not been established. Methods: Twenty-four-hour Holter recordings of 279 patients with ACS were initiated within 45 minutes of emergency department arrival; recordings with ≥18 hours of sinus rhythm were selected for HRV analysis (number [N] =193. Time domain, frequency domain, and nonlinear HRV were examined. Survival analysis was performed. Results: During the 1-year follow-up, 94 patients were event-free, 82 were readmitted, and 17 died. HRV was altered in relation to outcomes. Predictors of rehospitalization included increased normalized high frequency power, decreased normalized low frequency power, and decreased low/high frequency ratio. Normalized high frequency >42 ms2 predicted rehospitalization while controlling for clinical variables (hazard ratio [HR] =2.3; 95% confidence interval [CI] =1.4–3.8, P=0.001. Variables significantly associated with death included natural logs of total power and ultra low frequency

    2012-01-01

    Full Text Available Background and Objective: The incidence of coronary artery disease (CAD is increasing in India. Recent data suggesting insulin resistance can predict cardiovascular disease independently of the other risk factors, such as hypertension, visceral obesity, or dyslipidemia, so a focus on the relation between acute coronary syndrome (ACS and insulin resistance is relevant. Several studies addressing serum lipoprotein ratios as surrogates for insulin resistance have found promising results. We analyzed the association of lipoprotein ratios with the homeostatic model assessment of insulin resistance (HOMA-IR. Methods: One hundred non-diabetic patients with impaired fasting glucose admitted with a diagnosis of ACS were included in the study. Admission fasting glucose and insulin concentrations were measured. The HOMA-IR was used to calculate insulin resistance. The fasting serum total cholesterol (TC, triglycerides (TG, and high-density lipoprotein (HDL-C levels are used to calculate following lipid ratios: TC/HDL-C and TG/HDL-C. The areas under the curves (AUC of the receiver operating characteristic curves (ROC were used to compare the power of these serum lipoprotein ratio markers. Results: Lipoprotein ratios were significantly higher in patients with HOMA Index >2 as compared to patients with Index <2. TG/HDL-C ratio and TC/HDL-C ratio were significantly correlated with HOMA-IR (P < 0.05 as obtained by Pearson′s correlation analysis (r = 0.4459, P = 0.0012; r = 0.4815, P = 0.0004; r = 0.3993; P = 0.0041, respectively. The area under the ROC curve of the TG/HDL-C and TC/HDL-C ratios for predicting insulin resistance was 0.80 (95% CI, 0.67-0.93, 0.78 (95% CI, 0.65-0.91, respectively. Conclusion: A plasma TG/HDL-C ratio and TC/HDL-C ratio provide a simple means of identifying insulin resistant and can be used as the markers of insulin resistance and cardiovascular diseases risk in adult non-diabetic patients.

    Although a robust relationship between aberrant serum polyunsaturated fatty acids (PUFAs) profile and coronary artery disease (CAD) has been reported, the details concerning the association between aberrant PUFAs profile and clinical feature of CAD are not fully discovered. Therefore, we investigated the relationship between serum PUFAs and clinical profiles in CAD patients. We classified 595 consecutive CAD patients, who underwent coronary angiography into 3 groups according to the clinical profiles of CAD (group A: early phase ACS, n = 96; group B: stable CAD with previous history of ACS, n = 259; group C: stable CAD without previous history of ACS, n = 240) and measured serum n-3 [eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA)] and n-6 [arachidonic acid (AA)] PUFAs. Serum EPA, DHA, and EPA/AA ratio were significantly low in the order of group A EPA; 48.1 (34.1-60.3) μg/ml, 61.7 (41.2-94.5) μg/ml, and 74.4 (52.7-104.9) μg/ml, DHA; 113.1 (92.8-135.1) μg/ml, 125.8 (100.4-167.2) μg/ml, and 140.1 (114.7-177.0) μg/ml, EPA/AA ratio; 0.31 (0.22-0.45), 0.39 (0.26-0.62), and 0.44 (0.31-0.69), medians with interquartile range, p EPA (p = 0.009) and EPA/AA ratio (p = 0.023), but not DHA and DHA/AA ratio, were negatively associated with clinical profiles of ACS in CAD patients. Significant correlation was not observed between PUFAs profile and severity of coronary stenosis. Low serum EPA and EPA/AA ratio correlates with clinical profiles of ACS in patients with CAD, regardless of the extent and severity of coronary artery stenosis. PMID:26233644

  11. Post-traumatic stress disorder (PTSD symptoms predict delay to hospital in patients with acute coronary syndrome.

    Jonathan D Newman

    Full Text Available BACKGROUND: Increased delay to hospital presentation with acute coronary syndrome (ACS is associated with poor outcomes. While demographic factors associated with this delay have been well described, scarce data are available on the role of modifiable factors, such as psychosocial disorders, on pre-hospital delay. Patients with symptoms of post-traumatic stress disorder (PTSD often avoid stressful situations and may delay presenting for care when they experience cardiac symptoms. It is unknown, however, whether PTSD symptoms negatively impact the time to presentation during an ACS. METHODS: We assessed the relationship between PTSD symptoms and pre-hospital delay in 241 adults with an ACS in the ongoing Prescription Use, Lifestyle, Stress Evaluation (PULSE study. RESULTS: Overall, 66% of patients were male; 40% were Hispanic or Latino. The mean age was 61.9±11.6 years old. PTSD symptoms were present in 17.8% of patients. Pre-hospital delay was longer for patients with PTSD symptoms compared to those without [geometric mean: 25.8 hours (95% CI 13.8-44.8 vs. 10.7 hours (95% CI 8.3-13.8]; P = 0.005. After multivariable adjustment for age, sex, ethnicity, depression, left ventricular ejection fraction and history of myocardial infarction, the mean pre-hospital delay was 173% (95% CI: 36%-450% longer for patients with versus without PTSD symptoms. CONCLUSION: Among patients presenting with an ACS, PTSD symptoms were independently associated with longer pre-hospital delays. Future studies of pre-hospital delay should examine the mechanisms underlying this association.

    The Food and Drug Administration and the European Medicines Agency sent a warning in 2010 discouraging the concomitant use of clopidogrel with omeprazole or esomeprazole. The purpose is to know the gastroprotective approach in patients with acute coronary syndrome (ACS) and the level of follow-up of the alert. In 17 hospitals with catheterization laboratory in Spain, 1 per region, we studied 25 consecutive patients per hospital whose diagnosis of discharge since October 1, 2013, had been any type of ACS. We analyzed their baseline clinical profile, the gatroprotective agents at admission and discharge and the antiplatelet therapy at discharge. The number of patients included was 425: age 67.2 ± 12.5 years, women 29.8%, diabetes 36.5%. The patients presented unstable angina in 21.6%, non-ST-elevation myocardial infarction in 35.3% and ST-elevation myocardial infarction in 43.1%. Conservative approach was chosen in 17.9%, bare-metal stents 32.2%, ≥ 1 drug-eluting stent 48.5%, and surgery 1.4%. Aspirin was indicated in 1.9%, aspirin + clopidogrel 73.6%, aspirin + prasugrel 17.6%, and aspririn + ticagrelor 6.8%. Gastroprotective agents were present in 40.2% patients at admission and this percentage increased to 93.7% at discharge. Of the 313 (73.6%) on clopidogrel in 96 (30.6%) was combined with omeprazole and 3 (0.95%) with esomeprazole, whereas the most commonly used was pantoprazole with 190 patients (44.7%). In conclusion, almost the totality of the patients with an ACS receive gastroprotective agents at the moment of discharge, most of them with proton-pump inhibitors. In one every 3 cases of the patients who are on clopidogrel, the recommendation of the Food and Drug Administration and the European Medicines Agency is not followed. PMID:26708640

    We examined incidence of depression after acute coronary syndrome (ACS) and whether the timing of depression onset influenced survival. All first-time hospitalizations for ACS (n = 97,793) identified in the Danish Patient Registry during 2001-2009 and a reference population were followed for depression and mortality via linkage to patient, prescription, and cause-of-death registries until the end of 2012. Incidence of depression (as defined by hospital discharge or antidepressant medication use) and the relationship between depression and mortality were examined using time-to-event models. In total, 19,520 (20.0%) ACS patients experienced depression within 2 years after the event. The adjusted rate ratio for depression in ACS patients compared with the reference population was 1.28 (95% confidence interval (CI): 1.25, 1.30). During 12 years of follow-up, 39,523 (40.4%) ACS patients and 27,931 (28.6%) of the reference population died. ACS patients with recurrent (hazard ratio (HR) = 1.62, 95% CI: 1.57, 1.67) or new-onset (HR = 1.66, 95% CI: 1.60, 1.72) depression had higher mortality rates than patients with no depression. In the reference population, the corresponding relative estimates for recurrent (HR =1.98, 95% CI: 1.92, 2.05) and new-onset (HR = 2.42, 95% CI: 2.31, 2.54) depression were stronger. Depression is common in ACS patients and is associated with increased mortality independently of time of onset, but here the excess mortality associated with depression seemed to be lower in ACS patients than in the reference population.

    Background Sex and neighborhood socioeconomic status (nSES) may independently affect the care and outcomes of acute coronary syndromes (ACS), partly through barriers in timely access to cardiac catheterization. We sought to determine whether sex modifies the association between nSES, and the receipt of cardiac catheterization and mortality following an ACS in a universal healthcare system. Methods and Results We studied 14,012 ACS patients admitted to cardiology services between April 18, 2004 and December 31, 2011 in Southern Alberta, Canada. We used multivariable logistic regression to compare the odds of cardiac catheterization within 2 and 30 days of admission and the odds of 30-day and 1-year mortality for men and women by quintile of neighborhood median household income. Significant relationships between nSES and the receipt of cardiac catheterization and mortality after ACS were detected for women but not men. When examined by nSES, each incremental decrease in neighborhood income quintile for women was associated with a 6% lower odds of receiving cardiac catheterization within 30 days (p=0.01) and a 14% higher odds of 30-day mortality (p=0.03). For men, each decrease in neighborhood income quintile was associated with a 2% lower odds of receiving catheterization within 30 days (p=0.10), and a 5% higher odds of 30-day mortality (p=0.36). Conclusions Associations between nSES and receipt of cardiac catheterization and 30-day mortality were noted for women but not men in a universal healthcare system. Care protocols designed to improve equity of access to care and outcomes are required, especially for low-income women. PMID:24895450

    2014-08-01

    A number of studies have established the effects of solar-geomagnetic activity on the human cardio-vascular system. It is plausible that the heliophysical conditions existing during and after hospital admission may affect survival in patients with acute coronary syndromes (ACS). We analyzed data from 1,413 ACS patients who were admitted to the Hospital of Kaunas University of Medicine, Lithuania, and who survived for more than 4 days. We evaluated the associations between active-stormy geomagnetic activity (GMA), solar proton events (SPE), and solar flares (SF) that occurred 0-3 days before and after admission, and 2-year survival, based on Cox's proportional-hazards model, controlling for clinical data. After adjustment for clinical variables, active-stormy GMA on the 2nd day after admission was associated with an increased (by 1.58 times) hazard ratio (HR) of cardiovascular death (HR = 1.58, 95 % CI 1.07-2.32). For women, geomagnetic storm (GS) 2 days after SPE occurred 1 day after admission increased the HR by 3.91 times (HR = 3.91, 95 % CI 1.31-11.7); active-stormy GMA during the 2nd-3rd day after admission increased the HR by over 2.5 times (HR = 2.66, 95 % CI 1.40-5.03). In patients aged over 70 years, GS occurring 1 day before or 2 days after admission, increased the HR by 2.5 times, compared to quiet days; GS in conjunction with SF on the previous day, nearly tripled the HR (HR = 3.08, 95 % CI 1.32-7.20). These findings suggest that the heliophysical conditions before or after the admission affect the hazard ratio of lethal outcome; adjusting for clinical variables, these effects were stronger for women and older patients.

    CD147 is an important molecule in the inflammation and proteolysis process. This molecule crucially contributes to the initial and progression of atherosclerotic lesions. A single nucleotide polymorphism in CD147 gene, the rs8259 T/A in the 3'-untranslated region, is responsible for its expression in various cells. This study assessed whether the genetic variation rs8259 is associated with acute coronary syndrome (ACS) and CD147. A total of 943 ACS subjects and 439 stable angina subjects, and 851 controls were genotyped for rs8259 polymorphism by polymerase chain reaction restriction fragment length polymorphism and DNA-sequencing method. Plasma soluble CD147 (sCD147) level was measured by enzyme-linked immunosorbent assay. CD147 mRNA and protein expression in peripheral blood mononuclear cells were tested by real-time quantitative polymerase chain reaction and western blot, respectively. We found that TT genotype and T-allele frequency of CD147 rs8259 in ACS patients were much lower than the other patient groups. Significant difference was not observed between stable angina and controls. CD147 T allele was negatively related to ACS. ACS patients exhibited the highest CD147 expression in peripheral blood mononuclear cells and plasma sCD147 level. The plasma sCD147 levels in the culprit vessel were higher than those in the radial artery. In ACS patients, AA gene carriers had the highest CD147 levels, whereas TT gene carriers had the lowest CD147 levels. Linear regression analysis showed that genotypes and disease conditions contributed 49% to the change of the plasma CD147 level. These results suggested that the single nucleotide polymorphism of CD147 gene rs8259 T/A was associated with ACS susceptibility. Allele T gene may decrease the relative risk of suffering from ACS through downregulation of CD147 expression. PMID:26496256

  17. Cardiovascular events in patients received combined fibrate/statin treatment versus statin monotherapy: Acute Coronary Syndrome Israeli Surveys data.

    Alexander Tenenbaum

    Full Text Available BACKGROUND: The effect of combination of fibrate with statin on major adverse cardiovascular events (MACE following acute coronary syndrome (ACS hospitalization is unclear. The main aim of this study was to investigate the 30-day rate of MACE in patients who participated in the nationwide ACS Israeli Surveys (ACSIS and were treated on discharge with a fibrate (mainly bezafibrate and statin combination vs. statin alone. METHODS: The study population comprised 8,982 patients from the ACSIS 2000, 2002, 2004, 2006, 2008 and 2010 enrollment waves who were alive on discharge and received statin. Of these, 8,545 (95% received statin alone and 437 (5% received fibrate/statin combination. MACE was defined as a composite measure of death, recurrent MI, recurrent ischemia, stent thrombosis, ischemic stroke and urgent revascularization. RESULTS: Patients from the combination group were younger (58.1±11.9 vs. 62.9±12.6 years. However, they had significantly more co-morbidities (hypertension, diabetes, current smokers and unfavorable cardio-metabolic profiles (with respect to glucose, total cholesterol, triglyceride and HDL-cholesterol. Development of MACE was recorded in 513 (6.0% patients from the statin monotherapy group vs. 13 (3.2% from the combination group, p = 0.01. 30-day re-hospitalization rate was significantly lower in the combination group: 68 (15.6% vs. 1691 (19.8% of patients, respectively; p = 0.03. Multivariable analysis identified the fibrate/statin combination as an independent predictor of reduced risk of MACE with odds ratio of 0.54, 95% confidence interval 0.32-0.94. CONCLUSION: A significantly lower risk of 30-day MACE rate was observed in patients receiving combined fibrate/statin treatment following ACS compared with statin monotherapy. However, caution should be exercised in interpreting these findings taking into consideration baseline differences between our observational study groups.

  18. Changes of CD4+CD25+Regulatory T Cells in Patients with Acute Coronary Syndrome and the Effects of Atorvastatin

    2007-01-01

    The function of CD4+CD25+regulatory T lymphocytes (Treg) in patients with acute coronary syndrome (ACS) and the effects of atorvastatin were investigated. Forty-eight patients with ACS were randomly divided into two groups: group C receiving conventional therapy (n=24), and group C+A receiving conventional therapy+atorvastatin (10 mg/day, n=24). T lymphocytes from ACS patients (before and 2 weeks after the treatment) or 18 healthy subjects were separated and the flow cytometry was used to measure the percentage of Treg. The inhibitory ability of Treg on effector T cells was determined by mixed lymphocyte reaction (MLR). ELISA was used to measure the serum levels of cytokines (IL-10, TGF-β1 and IFN-γ) before and after treatment. The results showed that as compared with normal control group, Treg percentage was decreased significantly (P<0.01), the in- hibitory ability of Treg on the T lymphocytes proliferation was reduced (P<0.01), IFN-γ, levels were increased and IL-10 and TGF-β1 levels were lowered in ACS patients. After treatment with atorvas- tatin, Treg percentage and the inhibitory ability of Treg on T lymphocytes proliferation were signifi- cantly increased in ACS patients. Serum IFN-γ, was decreased significantly, while IL-10 and TGF-β1 were elevated significantly as compared with the non-atorvastatin group. The number of Treg was positively correlated with serum TGF-β1, but negatively with serum IFN-γ and CRP. It was concluded that ACS was associated with decreased number and defected function of Treg, which may play an important role in initiating immune-inflammatory response in ACS. The inhibitory ef- fects of atorvastatin on inflammation in ACS may be due to its beneficial effects on Treg and restora- tion of immune homeostasis.

    rate (GFR) was calculated by using the Modification of Diet in Renal Disease formula. RESULTS: The absolute differences in favor of fondaparinux (efficacy and safety) were most marked in patients with a GFR less than 58 mL/min per 1.73 m2; the largest differences occurred in major bleeding events. At 9......BACKGROUND: A recent randomized, controlled trial, the Fifth Organization to Assess Strategies in Acute Ischemic Syndromes (OASIS 5) trial, reported that major bleeding was 2-fold less frequent with fondaparinux than with enoxaparin in acute coronary syndromes (ACS). Renal dysfunction increases the...... risk for major bleeding. OBJECTIVE: To compare the efficacy and safety of fondaparinux and enoxaparin over the spectrum of renal dysfunction observed in the OASIS 5 trial. DESIGN: Subgroup analysis of a randomized, controlled trial. SETTING: Patients presenting to the hospital with non...

    Acute coronary syndrome is a leading cause of emergency medical treatment and hospitalization in Poland. High-speed electrocardiogram (ECG) has shown good accuracy of the initial diagnosis and of the final diagnosis in treated cardiac patients. Initial diagnosis and definitive diagnosis were analyzed statistically (PECG analysis (at the stage of prevention). This article presents the inclusion of ECG in the prevention process and shows that it allows for early detection of cardiovascular diseases. In Poland, ST-segment elevation myocardial infarction patients are identified in the ambulance that reduces time to door-to-balloon. PMID:27540297

    MicroRNAs (miRNAs) are a novel class of small, non-coding RNAs that play a significant role in both inflammatory and cardiovascular diseases. Immune cells, especially T helper (Th) cells, are critical in the development of atherosclerosis and the onset of acute coronary syndrome (ACS). To assess whether inflammation-related miRNAs (such as miR-155, 146a, 21, 125a-5p, 125b, 31) are involved in the imbalance of Th cell subsets in patients with ACS, we measured the expression of related miRNAs i...

    Conclusions: ACS patients in Yemen present at a relatively young age with high prevalence of Smoking, khat chewing and hypertension. STEMI patients present late, and their acute management is poor. In-hospital evidence-based medication rates are high, but coronary revascularization procedures were very low. In-hospital mortality was high and long-term mortality rates increased two folds compared with the in-hospital mortality.

  7. THE ROLE OF CLOPIDOGREL IN PATIENTS WITH ACUTE CORONARY SYNDROME AFTER THE EMERGENCE OF MORE POWERFUL INHIBITORS OF P2Y12 RECEPTOR

    S. R. Gilyarevsky

    2014-07-01

    Full Text Available The role of P2Y12 receptor blocker clopidogrel after the introduction into clinical practice of new, more powerful and stable operating drugs belonging to this class of antiplatelet agents is discussed. The advantages and disadvantages of each of the currently used antiplatelet drugs that block the receptor P2Y12 are reviewed. On the basis of the analysis concludes that, despite the emergence of new antiplatelet agents clopidogrel, appears to be widely used for a long time in the treatment of patients with acute coronary syndrome and / or after coronary stenting. This is primarily due to the presence of large evidence base, and confirmation of safety of long-term therapy clopidogrel.

    Acute kidney injury (AKI) is a common complication after coronary angiography. Early biomarkers of this disease are needed since increase in serum creatinine levels is a late marker. To assess the usefulness of urinary kidney injury molecule-1 (uKIM-1), neutrophil gelatinase-associated lipocalin (uNGAL) and liver-type fatty acid-binding protein (uL-FABP) for early detection of AKI in these patients, comparing their performance with another group of cardiac surgery patients. Biomarkers were measured in 193 patients, 12 h after intervention. In the ROC analysis, AUC for KIM-1, NGAL and L-FABP was 0.713, 0.958 and 0.642, respectively, in the coronary angiography group, and 0.716, 0.916 and 0.743 in the cardiac surgery group. Urinary KIM-1 12 h after intervention is predictive of AKI in adult patients undergoing coronary angiography, but NGAL shows higher sensitivity and specificity. L-FABP provides inferior discrimination for AKI than KIM-1 or NGAL in contrast to its performance after cardiac surgery. This is the first study showing the predictive capacity of KIM-1 for AKI after coronary angiography. Further studies are still needed to answer relevant questions about the clinical utility of biomarkers for AKI in different clinical settings. PMID:24989970

    Full Text Available BACKGROUND: Contemporary data remains limited regarding mortality and major adverse cardiac events (MACE outcomes in patients undergoing PCI for different manifestations of coronary artery disease. OBJECTIVES: We evaluated mortality and MACE outcomes in patients treated with PCI for STEMI (ST-elevation myocardial infarction, NSTEMI (non ST-elevation myocardial infarction and stable angina through analysis of data derived from the Nobori-2 study. METHODS: Clinical endpoints were cardiac mortality and MACE (a composite of cardiac death, myocardial infarction and target vessel revascularization. RESULTS: 1909 patients who underwent PCI were studied; 1332 with stable angina, 248 with STEMI and 329 with NSTEMI. Age-adjusted Charlson co-morbidity index was greatest in the NSTEMI cohort (3.78±1.91 and lowest in the stable angina cohort (3.00±1.69; P<0.0001. Following Cox multivariate analysis cardiac mortality was independently worse in the NSTEMI vs the stable angina cohort (HR 2.31 (1.10-4.87, p = 0.028 but not significantly different for STEMI vs stable angina cohort (HR 0.72 (0.16-3.19, p = 0.67. Similar observations were recorded for MACE (<180 days (NSTEMI vs stable angina: HR 2.34 (1.21-4.55, p = 0.012; STEMI vs stable angina: HR 2.19 (0.97-4.98, p = 0.061. CONCLUSIONS: The longer-term Cardiac mortality and MACE were significantly worse for patients following PCI for NSTEMI even after adjustment of clinical demographics and Charlson co-morbidity index whilst the longer-term prognosis of patients following PCI STEMI was favorable, with similar outcomes as those patients with stable angina following PCI.

    Cardiovascular disease is the leading cause of early death and morbidity in developed countries and is becoming a growing problem in many developing countries. Currently, anti-coagulants play a major role in the management of the acute phase in association or not with reperfusion strategies. The combination of clopidogrel and aspirin, in accordance with the results of large randomized trials, is the treatment of reference. However two new drugs, a thienopyridine (prasugrel), and a cyclo-pentyl-triazolo-pyridine (ticagrelor) have shown their interest in major studies in comparison with clopidogrel. As a result, several effective P2Y12 receptor antagonist anti-platelet agents are now available in the therapeutic arsenal, and the cardiologist have to tailored the best drug scheme according the balance between the risk of hemorrhage and the benefits with regard to the ischemia to determine the optimal prescription for every patient.

    2016-06-01

    Hyperglycemia negatively affects cardiovascular variables that are also adversely affected by increased geomagnetic activity. It is likely that geomagnetic storms (GS) could have a stronger negative impact on these patients. We analyzed data on 1548 randomly selected patients with acute coronary syndrome (ACS) who were admitted inpatient treatment in Kaunas city, during 2000-2003. We evaluated the associations of GS, solar proton events (SPE), and high-speed solar wind (HSSW) (solar wind speed ≥600 km/s) with the risk of ACS in patients with diabetes mellitus (DM) and the metabolic syndrome (MS) by using logistic regression with categorical predictors. During days of HSSW, the risk of ACS in DM patients increased by 1.95 times (OR = 1.95, 95 % CI 1.36-2.79) as compared to days without either of these events or 2 days prior to or after them. In the multivariate model, the risk of ACS in DM patients was associated with days of HSSW and 1-2 days after (OR = 1.40, 95 % CI 1.01-1.93), with days of GS lasting >1 day and occurring on days of HSSW or 1-2 days after (OR = 2.31, 95 % CI 1.28-4.17), and with the onset of SPE (OR = 2.72 (1.09-6.83)). The risk of ACS in MS patients was associated with days of GS and 1-2 days prior or after GS (OR = 1.31 (1.00-1.73)); an additional impact was established if these days coincided with days of HSSW or 1-2 days before (OR = 2.16 (1.39-3.35)). These findings suggest that not only GS but also HSSW and changes in space weather conditions prior to SPE affect the human cardiovascular system.

  12. Rarity of isolated pulmonary embolism and acute aortic syndrome occurring outside of the field of view of dedicated coronary CT angiography

    Background Although triple rule-out CT angiography (TRO) to simultaneously evaluate acute coronary syndrome (ACS), pulmonary embolism (PE), and acute aortic syndrome (AAS) is increasingly used in many institutions, TRO is inevitably associated with increased radiation exposure due to extended z-axis coverage compared with dedicated coronary CT angiography (DCTA). Purpose To determine the frequency of exclusion of findings of AAS, PE, and significant incidental non-cardiac pathology that may be the cause of acute chest pain when using a restricted DCTA field of view (FOV). Material and Methods We retrospectively reviewed CT images and charts of 103 patients with acute PE and 50 patients with AAS. Either non-ECG gated dedicated pulmonary or aortic CT angiography was performed using 16- or 64-slice multidetector CT (MDCT). We analyzed the incidence of isolated PE, AAS, or significant non-cardiac pathology outside of DCTA FOV (i.e. from tracheal carina to the base of heart). Results There were two cases of isolated PE (2/103, 1.9%) excluded from the FOV of DCTA. One case of PE was isolated to the subsegmental pulmonary artery in the posterior segment of the right upper lobe. In the second case, pulmonary embolism in the left main pulmonary artery was located out of the FOV of DCTA because the left main pulmonary artery was retracted upwardly by fibrotic scar in the left upper lobe due to prior tuberculosis. There was no case of AAS and significant non-cardiac pathology excluded from the FOV of DCTA. AAS (n = 50) consisted of penetrating atherosclerotic ulcer (n = 7), intramural hematoma (n = 5) and aortic dissection (n = 38). Conclusion As isolated PE, AAS, and significant non-cardiac pathology outside of the DCTA FOV rarely occur, DCTA may replace TRO in the evaluation of patients with non-specific acute chest pain and a low pre-test probability of PE or aortic dissection

    With potent analgesic properties, perceived hemodynamic benefits and limited alternatives, morphine is the analgesic mainstay for patients with nitrate resistant chest pain due to acute Myocardial Infarction (MI). However, observational data suggest that morphine administration during MI may have negative consequences. While vomiting, hypotension and respiratory depression are established side effects, recent reports have demonstrated attenuated and delayed oral anti-platelet agent absorption, as well as suboptimal reperfusion after MI, all of which may translate into adverse cardiovascular outcomes. These data have resulted in reduced support for morphine in recent European and U.S. clinical practice guidelines for MI; despite the absence of any prospective randomized outcomes trials addressing this question. As such, randomized trials are now necessary to confirm whether or not morphine, which is administered in up to 30% of MI cases, causes adverse clinical outcomes in these patients. However, given that placebo-controlled randomized trial designs evaluating morphine in MI are limited by an ethical requirement for appropriate analgesia, alternative investigational approaches may be necessary. In this article we review the updated evidence for morphine in MI and outline novel strategies that may facilitate future investigation of this clinical dilemma. PMID:27264228

    The objective of this study was to evaluate the performance of the ICD-10 (International Classification of Diseases and Related Health Problems, 10(th) Edition) coding in the French hospitalization database (PMSI) to identify acute coronary syndrome (ACS) occurrence. Eligible hospitalizations were those that occurred at the Bordeaux teaching hospitals between 1 January 2011 and 31 December 2011 and had one of the ICD-10 codes related to ischaemic heart diseases (I20 to I25, excluding I23 and I25.2). Among these, 100 hospitalizations were randomly selected; for each case, the ACS diagnosis was confirmed/excluded after medical file examination by an independent events validation committee and the performance of codes, and combinations of codes, to identify ACS was evaluated by calculating the positive predictive value (PPV). Of the individual codes, I20.0, I21 and I24 had the highest PPV; 100.0% for I24 (95%CI [15.8-100.0]); 90.0% for I21 (95%CI [76.3-97.2]); and 66.7% for I20.0 (95%CI [38.4-88.2]). The combination of I20.0 or I24 codes was able to identify 12 of the 56 validated ACS cases with a PPV of 70.6% (95%CI [44.0-89.7]), the combination of I21 or I24 identified 38 cases with a PPV of 90.5% (95%CI [77.4-97.3]), the combination of I20.0 or I21 identified 46 cases with a PPV of 83.6% (95%CI [71.2-92.2]), and the combination of I20.0, I21 or I24 identified 48 cases with a PPV of 84.2% (95%CI [72.1-92.5]). The combination of I20.0, I21 or I24 codes had the best performance to identify occurrence of ACS in the French hospitalization database. PMID:26301735

    Full Text Available Adherence to guidelines is associated with improved outcomes of patients with acute coronary syndrome (ACS. Clinical registries developed to assess quality of care at discharge often do not collect the reasons for non-prescription for proven efficacious preventive medication in Continental Europe. In a prospective cohort of patients hospitalized for an ACS, we aimed at measuring the rate of recommended treatment at discharge, using pre-specified quality indicators recommended in cardiologic guidelines and including systematic collection of reasons for non-prescription for preventive medications.In a prospective cohort with 1260 patients hospitalized for ACS, we measured the rate of recommended treatment at discharge in 4 academic centers in Switzerland. Performance measures for medication at discharge were pre-specified according to guidelines, systematically collected for all patients and included in a centralized database.Six hundred and eighty eight patients(54.6% were discharged with a main diagnosis of STEMI, 491(39% of NSTEMI and 81(6.4% of unstable angina. Mean age was 64 years and 21.3% were women. 94.6% were prescribed angiotensin converting enzyme inhibitors/angiotensin II receptor blockers at discharge when only considering raw prescription rates, but increased to 99.5% when including reasons non-prescription. For statins, rates increased from 98% to 98.6% when including reasons for non-prescription and for beta-blockers, from 82% to 93%. For aspirin, rates further increased from 99.4% to 100% and from to 99.8% to 100% for P2Y12 inhibitors.We found a very high adherence to ACS guidelines for drug prescriptions at discharge when including reasons for non-prescription to drug therapy. For beta-blockers, prescription rates were suboptimal, even after taking into account reason for non-prescription. In an era of improving quality of care to achieve 100% prescription rates at discharge unless contra-indicated, pre-specification of reasons

    Objectives To characterize the morphological features of plaque erosion and calcified nodule in patients with acute coronary syndrome (ACS) by optical coherence tomography (OCT). Background Plaque erosion and calcified nodule have not been systematically investigated in vivo. Methods One hundred and twenty-six patients with ACS who had undergone pre-intervention OCT imaging were included. The culprit lesions were classified as plaque rupture (PR), erosion (OCT-erosion), calcified nodule (OCT-CN), or others using a new set of diagnostic criteria for OCT. Results The incidences of PR, OCT-erosion, and OCT-CN were 43.7%, 31.0%, and 7.9%, respectively. Patients with OCT-erosion were the youngest compared with those with PR and OCT-CN (53.8±13.1 years vs. 60.6±11.5 years, 65.1±5.0 years, p=0.005). Compared with patients with PR, presentation with non-ST-segment elevation ACS (NSTE-ACS) was more common in patients with OCT-erosion (61.5% vs. 29.1%, p=0.008) and OCT-CN (100% vs. 29.1%, p<0.001). OCT-erosion had a lower frequency of lipid plaque (43.6% vs. 100%, p<0.001), thicker fibrous cap (169.3±99.1 μm vs. 60.4±16.6 μm, p<0.001), and smaller lipid arc (202.8±73.6° vs. 275.8±60.4°, p<0.001) than PR. The diameter stenosis was least severe in OCT-erosion followed by OCT-CN and PR (55.4±14.7% vs. 66.1±13.5% vs. 68.8±12.9%, p<0.001). Conclusions OCT is a promising modality for identifying OCT-erosion and OCT-CN in vivo. OCT-erosion is a frequent finding in patients with ACS, especially in those with NSTE-ACS and younger patients. OCT-CN is the least common etiology for ACS and is more common in older patients. PMID:23810884

    Background. Acute promyelocytic leukemia is characterized by t(15;17). This leads to the formation of PML/RARα which blocks the differentiation of blasts at the stage of promyelocytes. This is reversed by all-trans-retinoic acid (ATRA), a vitamin A derivative. Acute myocardial ischemia is a rare side effect of ATRA. Case Report. We report a case of acute coronary syndrome manifesting as an adverse effect of ATRA in a lady with APL who had no other risk factors for cardiovascular disease. Conclusions. We emphasize the need for high index of suspicion for the diagnosis of this entity. In the light of this case, the rare instances of ATRA associated acute myocardial ischemia recorded in the literature and the options available for treatment of acute promyelocytic leukemia sans ATRA have been reviewed.
