    To test associations between heart rate variability (HRV), depressed mood, and positive affect in patients with suspected coronary artery disease (CAD). Depression is associated with impaired HRV post acute cardiac events, but evidence in patients with stable coronary artery disease (CAD) is inconsistent. Seventy-six patients (52 men, 24 women; mean age = 61.1 years) being investigated for suspected CAD on the basis of symptomatology and positive noninvasive tests, completed 24-hour electrocardiograms. The Beck Depression Inventory (BDI) was administered, and positive and depressed affect was measured over the study period with the Day Reconstruction Method (DRM). A total of 46 (60.5%) patients were later found to have definite CAD. HRV was analyzed, using spectral analysis. Typical diurnal profiles of HRV were observed, with greater normalized high frequency (HF) and lower normalized low frequency (LF) power in the night compared with the day. BDI depression scores were not consistently associated with HRV. But positive affect was associated with greater normalized HF power (p = .039) and reduced normalized LF power (p = .007) independently of age, gender, medication with beta blockers, CAD status, body mass index, smoking, and habitual physical activity level. In patients with definite CAD, depressed affect assessed using the DRM was associated with reduced normalized HF power and heightened normalized LF power (p = .007) independently of covariates. Relationships between depression and HRV in patients with CAD may depend on affective experience over the monitoring period. Enhanced parasympathetic cardiac control may be a process through which positive affect protects against cardiovascular disease.

    The emergency department evaluation for suspected acute coronary syndrome (ACS) is common, costly, and challenging. Risk scores may help standardize clinical care and screening for research studies. The Thrombolysis in Myocardial Infarction (TIMI) and HEART are two commonly cited risk scores. We tested the null hypothesis that the TIMI and HEART risk scores have equivalent test characteristics. We analyzed data from the Internet Tracking Registry of Acute Coronary Syndromes (i*trACS) from 9 EDs on patients with suspected ACS, 1999-2001. We excluded patients with an emergency department diagnosis consistent with ACS, or without sufficient data to calculate TIMI and HEART scores. The primary outcome was 30-day major adverse cardiovascular events, including all-cause death, acute myocardial infarction, and urgent revascularization. We describe test characteristics of the TIMI and HEART risk scores. The study cohort included 8255 patients with 508 (6.2%) 30-day major adverse cardiovascular events. Receiver operating curve and reclassification analyses favored HEART [c statistic: 0.753, 95% confidence interval (CI): 0.733-0.773; continuous net reclassification improvement: 0.608, 95% CI: 0.527-0.689] over TIMI (c statistic: 0.678, 95% CI: 0.655-0.702). A HEART score 0-3 [negative predictive value (NPV) 0.982, 95% CI: 0.978-0.986; positive predictive value (PPV) 0.103, 95% CI: 0.094-0.113; likelihood ratio (LR) positive 1.76; LR negative 0.28] demonstrates similar or superior NPV/PPV/LR compared with TIMI = 0 (NPV 0.978, 95% CI: 0.971-0.983; PPV 0.077, 95% CI: 0.071-0.084; LR positive 1.28; LR negative 0.35) and TIMI = 0-1 (NPV 0.963, 95% CI: 0.958-0.968; PPV 0.102, 95% CI: 0.092-0.113; LR positive 1.73; LR negative 0.58). The HEART score has better discrimination than TIMI and outperforms TIMI within previously published "low-risk" categories.

    Recent guidelines for the workup of patients with chest pain and suspected coronary artery disease include coronary computed tomography angiography (CTA). However, its diagnostic value may be limited in patients with severe coronary calcification. We investigated the relationship between the extent of coronary calcium and the ability of coronary CTA to rule out significant stenoses in a series of consecutive patients with suspected coronary artery disease. 2614 consecutive patients with suspected coronary artery disease in whom coronary calcium scoring and coronary CTA had been performed by Dual Source CT were analyzed. The ability of coronary CTA to rule out coronary artery stenoses (fully evaluable coronary arteries and absence of any luminal stenosis >75%) was analyzed relative to the coronary calcium score. The median coronary calcium score was 12, with calcium present in 60.5% of all patients. Coronary CTA ruled out stenoses in 82% of patients, while in 18% of patients at least one stenosis was found or could not be excluded. The threshold above which coronary CTA permitted to rule out stenoses in less than 50% of patients was an "Agatston Score" of 287. This threshold was significantly lower for male patients (213 vs. 330), for patients with a heart rate >65 beats/min (157 vs. 317) and for patients with a body mass index ≥25 kg/m(2) (208 vs. 392). The evaluability of coronary arteries decreased with increasing amounts of calcium and differed significantly between heart rates ≤65 beats/min and >65 beats/min (p coronary CTA permits to rule out coronary artery stenoses in less than 50% of cases.

    In patients with coronary heart disease anxiety is often overlooked. Symptoms of anxiety are often similar to coronary heart disease symptoms. The prevalence of anxiety in general population and coronary heart disease patients is very high. While the underlying pathophysiology of the connection remains unclear, anxiety lowers the quality of life and is a factor for a higher risk of morbidity and mortality due to coronary heart disease.

    This study assessed behavioral activity, dietary and emotional variables among patient cohorts with angina pectoris, atypical chest pain, and no chest pain in whom coronary disease is suspected. Questionnaire responses of 3,899 employed male patients at the time of coronary arteriography were analyzed. Patients with angina pectoris had high levels of coronary-prone and neurotic attitudes, and fatigue variables including feeling unrested on awakening, easy fatiguability, reducing activity at work and arriving home tired. Atypical chest pain patients showed coronary-prone and neurotic attitudes similar to the angina pectoris group but had less coronary occlusion and lower levels of fatigue variables. Compared to the other groups, atypical chest pain patients were more likely to skip breakfast and showed a trend to eat fast. These findings suggest that including assessment of activity levels, fatiguability, eating behavior, neurotic traits and coronary-prone attitudes at time of coronary arteriography can have some limited value for patients with chest pain who may seek cardiac treatment but could benefit from alternative approaches.

    Nitroglycerine-induced vasodilation, an index of endothelium-independent vasodilation, is measured for the assessment of vascular smooth muscle cell function or alterations of vascular structure. Both coronary and brachial artery responses to nitroglycerine have been demonstrated to be independent prognostic markers of cardiovascular events. The purpose of this study was to evaluate the nitroglycerine-induced vasodilation in coronary and brachial arteries in the same patients. We measured nitroglycerine-induced vasodilation in coronary and brachial arteries in 30 subjects with suspected coronary artery disease who underwent coronary angiography (19 men and 11 women; mean age, 69.0±8.8years; age range, 42-85years). The mean values of nitroglycerine-induced vasodilation in the brachial artery, left anterior descending coronary artery, and left circumflex coronary artery were 12.6±5.2%, 11.6±10.3%, and 11.9±11.0%, respectively. Nitroglycerine-induced vasodilation in the brachial artery correlated significantly with that in the left anterior descending coronary artery (r=0.43, P=0.02) and that in the left circumflex coronary artery (r=0.49, P=0.006). There was also a significant correlation between nitroglycerine-induced vasodilation in the left anterior descending coronary artery and that in the left circumflex coronary artery (r=0.72, Parteries and that in coronary arteries are simultaneously present. Nitroglycerine-induced vasodilation in the brachial artery could be used as a surrogate for that in a coronary artery and as a prognostic marker for cardiovascular events.

    Full Text Available AbstractBackground:Guidelines recommend that in suspected stable coronary artery disease (CAD, a clinical (non-invasive evaluation should be performed before coronary angiography.Objective:We assessed the efficacy of patient selection for coronary angiography in suspected stable CAD.Methods:We prospectively selected consecutive patients without known CAD, referred to a high-volume tertiary center. Demographic characteristics, risk factors, symptoms and non-invasive test results were correlated to the presence of obstructive CAD. We estimated the CAD probability based on available clinical data and the incremental diagnostic value of previous non-invasive tests.Results:A total of 830 patients were included; median age was 61 years, 49.3% were males, 81% had hypertension and 35.5% were diabetics. Non-invasive tests were performed in 64.8% of the patients. At coronary angiography, 23.8% of the patients had obstructive CAD. The independent predictors for obstructive CAD were: male gender (odds ratio [OR], 3.95; confidence interval [CI] 95%, 2.70 - 5.77, age (OR for 5 years increment, 1.15; CI 95%, 1.06 - 1.26, diabetes (OR, 2.01; CI 95%, 1.40 - 2.90, dyslipidemia (OR, 2.02; CI 95%, 1.32 - 3.07, typical angina (OR, 2.92; CI 95%, 1.77 - 4.83 and previous non-invasive test (OR 1.54; CI 95% 1.05 - 2.27.Conclusions:In this study, less than a quarter of the patients referred for coronary angiography with suspected CAD had the diagnosis confirmed. A better clinical and non-invasive assessment is necessary, to improve the efficacy of patient selection for coronary angiography.

    The relationships between two behavioral patterns, cardiac risk factors, and coronary heart disease are investigated. Risk factors used in the analysis were family history of coronary disease, smoking, cholesterol, obesity, systotic blood pressure, diastolic blood pressure, blood sugar, uric acid, erythrocyte sedimentation rate, and white blood unit. It was found that conventional, non-behavioral pattern risk factors alone were not significantly related to coronary heart disease.

    Full Text Available Neoangiogenesis in coronary heart disease is a protective reaction aimed to improve ischemic myocardial perfusion, by increasing the number and size of arterial collaterals. Placental growth factor (PlGF is one of the key peptides regulating angiogenic processes in atherosclerosis. In particular, a number of investigators have shown that injection of recombinant PlGF into the system or regional blood flow can stimulate neoangiogenesis. On the other hand, there is evidence confirming the involvement of PlGF in the progression of atherosclerosis and in the development of acute coronary syndrome. In this connection, the problem of investigating the efficiency and safety of possible use of PlGF preparations, as well as its place in the diagnosis of coronary heart disease and acute coronary syndrome remains urgent

    The aim of this review is to summarize the incidence, prevalence, trend in mortality, and general prognosis of coronary heart disease (CHD) and a related condition, acute coronary syndrome (ACS). Although CHD mortality has gradually declined over the last decades in western countries, this condition still causes about one-third of all deaths in people older than 35 years. This evidence, along with the fact that mortality from CHD is expected to continue increasing in developing countries, illustrates the need for implementing effective primary prevention approaches worldwide and identifying risk groups and areas for possible improvement.

    Positron emission tomography (PET) myocardial perfusion imaging has higher spatial resolution than conventional single photon emission computed tomography (SPECT) imaging and allows accurate and reproducible quantification of myocardial blood flow (MBF). In this article, we describe the role of PET myocardial perfusion imaging in clinical decision making in children with suspected coronary abnormalities. We performed a PET myocardial perfusion study using N-13 ammonia in 10 children (median age, 14 years; range, 1-17 years). The indications included exercise-induced chest pain and ST segment changes during exercise testing, coronary artery ectasia, hypertrophic cardiomyopathy with myocardial bridging of the left anterior descending coronary artery, and suspected left coronary stenosis in an infant with William's syndrome. MBF was assessed at baseline and during adenosine hyperemia in all 10 patients and postexercise in 8 patients. Myocardial perfusion was homogeneous at baseline in all 10 patients, during adenosine perfusion in 9 of 10 patients, and postexercise in all 8 patients. Three patients with homogeneous rest and stress perfusion had impaired myocardial flow reserve. The infant with William's syndrome developed a large, reversible perfusion defect in the left coronary territory during adenosine stress and underwent surgical repair. Myocardial flow reserve findings were valuable for clinical decision making in individual patients. We conclude that MBF quantification with N-13 ammonia and PET provides supplemental perfusion information and is helpful in clinical decision making in children with suspected coronary abnormalities.

    Extensive work has been done over recent years to improve the spatial and temporal resolution of electrocardiogram (ECG)-gated cardiac computed tomography (CT). Advances in both hardware and software analysis have enabled the development of non-invasive coronary angiography. However, these high-quality examinations lend themselves to multiple additional applications beyond coronary angiography. In this review, we illustrate and discuss some established and some emerging applications of ECG-gated cardiac CT beyond the assessment of suspected coronary disease, particularly in light of recent recommendations on the appropriate use of this technology.

    We investigated the association between phosphate and the risk of adverse clinical outcomes in patients with manifest cardiovascular disease (CVD). Observational study of patients hospitalized during 2006-2011 in Stockholm, Sweden, because of suspected acute coronary syndrome (ACS). The exposure was serum phosphate during the hospitalization. We modeled the association between phosphate and in-hospital death or in-hospital events (composite of myocardial infarction, cardiogenic shock, resuscitated cardiac arrest, atrial fibrillation, or atrioventricular block) as well as the one-year post-discharge risk of death or cardiovascular event (composite of myocardial re-infarction, heart failure and stroke). Confounders included demographics, comorbidities, kidney function, diagnoses, in-hospital procedures and therapies. Included were 2547 patients (68% men, mean age 67±14years) with median phosphate of 1.10 (range 0.14-4.20) mmol/L. During hospitalization, 198 patients died and 328 suffered an adverse event. Within one year post-discharge, further 381 deaths and 632 CVD events occurred. The associations of phosphate with mortality and CVD were J-shaped, with highest risk magnitudes at higher phosphate levels. For instance, compared to patients in the 50th percentile of phosphate distribution, those above the 75th percentile (1.3mmol/L, normal range) had significantly higher odds for in-hospital death [odds ratio 1.36, 95% confidence interval (CI) (1.08-1.71)] and of CVD post-discharge [sub-hazard ratios 1.17 (1.03-1.33)]. In patients with suspected ACS, both higher and lower phosphate levels associated with increased risk of adverse outcomes during the index hospitalization and within one year post-discharge. The risk association was present already within normal-range serum phosphate values. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Coronary Heart Disease (CHD) is associated with emotions, especially negative ones, namely anxiety and depression. Emotional Intelligence (EI) is a psychological model that consists of a variety of emotional skills. The aim of the present study was to examine the relation between different dimensions of Emotional Intelligence and coronary heart disease. A total of 300 participants were studied during a 3-year period in an attempt to partially replicate and further expand a previous study conducted in Greece among CHD patients, which indicated a strong association between certain dimensions of Emotional Intelligence and the incidence of CHD. All participants completed a self-report questionnaire, assessing several aspects of Emotional Intelligence. The results showed that there is a link between the regulation of emotions and the occurrence of CHD. The evidence reported in the present study makes stronger the claim that EI plays a significant role in the occurrence of CHD.

  13. Coronary computed tomography angiography (CCTA) and cardiac magnetic resonance (CMR) imaging in the assessment of patients presenting with chest pain suspected for acute coronary syndrome.

    De Filippo, Massimo; Capasso, Raffaella

    2016-07-01

    Acute chest pain is an important clinical challenge and a major reason for presentation to the emergency department. Although multiple imaging techniques are available to assess patients with suspected acute coronary syndrome (ACS), considerable interest has been focused on the use of non-invasive imaging options as coronary computed tomography angiography (CCTA) and cardiac magnetic resonance (CMR). According to several recent evidences, CCTA has been shown to represent a useful tool to rapidly and accurately diagnose coronary artery disease (CAD) in patients with low to intermediate cardiovascular risk. CCTA examination has the unique ability to non-invasively depict the coronary anatomy, not only allowing visualization of the lumen of the arteries in order to detect severe stenosis or occlusion responsible of myocardial ischemia, but also allows the assessment of coronary artery wall by demonstrating the presence or absence of CAD. However, routine CCTA is not able to differentiate ischemic from non-ischemic chest pain in patients with known CAD and it does not provide any functional assessment of the heart. Conversely, CMR is considered the gold standard in the evaluation of morphology, function, viability and tissue characterization of the heart. CMR offers a wide range of tools for diagnosing myocardial infarction (MI) at least at the same time of the elevation of cardiac troponin values, differentiating infarct tissue and ischemic myocardium from normal myocardium or mimicking conditions, and distinguishing between new and old ischemic events. In high-risk patients, with acute and chronic manifestations of CAD, CMR may be preferable to CCTA, since it would allow detection, differential diagnosis, prognostic evaluation and management of MI.

  14. Highly sensitive troponin and coronary computed tomography angiography in the evaluation of suspected acute coronary syndrome in the emergency department.

    2016-08-07

    The evaluation of patients presenting to the emergency department with suspected acute coronary syndrome (ACS) remains a clinical challenge. The traditional assessment includes clinical risk assessment based on cardiovascular risk factors with serial electrocardiograms and cardiac troponin measurements, often followed by advanced cardiac testing as inpatient or outpatient (i.e. stress testing, imaging). Despite this costly and lengthy work-up, there is a non-negligible rate of missed ACS with an increased risk of death. There is a clinical need for diagnostic strategies that will lead to rapid and reliable triage of patients with suspected ACS. We provide an overview of the evidence for the role of highly sensitive troponin (hsTn) in the rapid and efficient evaluation of suspected ACS. Results of recent research studies have led to the introduction of hsTn with rapid rule-in and rule-out protocols into the guidelines. Highly sensitive troponin increases the sensitivity for the detection of myocardial infarction and decreases time to diagnosis; however, it may decrease the specificity, especially when used as a dichotomous variable, rather than continuous variable as recommended by guidelines; this may increase clinician uncertainty. We summarize the evidence for the use of coronary computed tomography angiography (CTA) as the rapid diagnostic tool in this population when used with conventional troponin assays. Coronary CTA significantly decreases time to diagnosis and discharge in patients with suspected ACS, while being safe. However, it may lead to increase in invasive procedures and includes radiation exposure. Finally, we outline the opportunities for the combined use of hsTn and coronary CTA that may result in increased efficiency, decreased need for imaging, lower cost, and decreased radiation dose.

    Patients with angina pectoris or myocardial infarction frequently present without evidence of cardiac-specific heart enzymes by laboratory analysis or specific pathologic electro-cardiogram findings. The current study analyzed the efficacy of the erythrocyte sedimentation rate as an additional potential indicator for coronary heart disease, the aim being to enable quicker identification of patients with angina pectoris or myocardial infarction so that they can be more rapidly treated. Patients with angina pectoris or myocardial infarction who had undergone a heart catheter examination were included in the study. The diagnosis of acute coronary heart disease was made by the physician who performed coronary angiography. Patients without coronary heart disease were used as a control group. The erythrocyte sedimentation rate was measured in all patients. Patients with angina pectoris or myocardial infarction and an inflammatory or tumor disease were excluded. The erythrocyte sedimentation rate was prolonged in 79 (58.09%) of 136 patients; 69 (50.74%) patients (95% confidence interval ±8.4%, 42.34%-59.14%) had coronary heart disease and a prolonged erythrocyte sedimentation rate. The erythrocyte sedimentation rate was prolonged in ten (7.35%) patients (95% confidence interval ±4.39%, 2.96%-11.74%) without coronary heart disease by coronary angiography. The specificity of the erythrocyte sedimentation rate for coronary heart disease was 70.59% and the sensitivity was 67.65%. Erythrocyte sedimentation rate may be a useful additional diagnostic criterion for coronary heart disease.

    To determine the relationship between the number,phenotype and functional status of dendritic cells (DCs) and coronary collateral circulation (CCC) in coronary heart disease (CHD). Forty patients with severe coronary stenosis were recruited and divided into a CCC formation group (Group A, n=22) and a non-CCC formation group (Group B, n=18). Density gradient centrifugation was applied to separate the mononuclear cells (MNCs) from coronary artery blood samples, and MNCs were cultured and proliferated in vitro. The morphology of DCs was observed under converted microscope. The number of harvested cells and DCs was counted by hematocytometer. Flow cytometry was applied to investigate the phenotype and the mean fluorescence intensity (MFI). Mixed lymphocyte reaction was used to test the function of DCs to stimulate the proliferation of T lymphocytes. Stimulation index (SI) was calculated and compared. (1) After in vitro proliferation, DCs were cultured successfully from the mononuclear cells from coronary artery blood samples and the morphology of DCs was not different in the 2 groups. (2) The number of mononuclear cells (MNC no) was (3.95+/-1.41)*10(6), in the CCC group and (2.76+/-0.92)*10(6) in the non-CCC group. The MNC number was significantly increased in the CCC group (P=0.003). (3) The number of DCs was (1.54+/-0.96)*10(6) in the CCC group, and (0.99+/-0.46)*10(6) in the non-CCC group (P=0.033). (4)There was no statistical significance in the percent of CD1a+, CD1a+CD80+, CD1a+CD83+, CD1a+CD86+ cells, and MFI in the 2 groups (P>0.05). (5) SI was 4.96+/-2.30 in the CCC group, whereas 2.66+/-1.04 in the non-CCC group. The SI in the CCC group increased significantly(P=0.0003). In CHD patients with severe coronary stenosis, patients with CCC formation have higher number of DCs and stronger potential of T lymphocyte stimulation.

    Full Text Available Unrecognized myocardial infarction (UMI is known to constitute a substantial portion of potentially lethal coronary heart disease. However, the diagnosis of UMI is based on the appearance of incidental Q-waves on 12-lead electrocardiography. Thus, the syndrome of non-Q-wave UMI has not been investigated. Delayed-enhancement cardiovascular magnetic resonance (DE-CMR can identify MI, even when small, subendocardial, or without associated Q-waves. The aim of this study was to investigate the prevalence and prognosis associated with non-Q-wave UMI identified by DE-CMR.We conducted a prospective study of 185 patients with suspected coronary disease and without history of clinical myocardial infarction who were scheduled for invasive coronary angiography. Q-wave UMI was determined by electrocardiography (Minnesota Code. Non-Q-wave UMI was identified by DE-CMR in the absence of electrocardiographic Q-waves. Patients were followed to determine the prognostic significance of non-Q-wave UMI. The primary endpoint was all-cause mortality. The prevalence of non-Q-wave UMI was 27% (50/185, compared with 8% (15/185 for Q-wave UMI. Patients with non-Q-wave UMI were older, were more likely to have diabetes, and had higher Framingham risk than those without MI, but were similar to those with Q-wave UMI. Infarct size in non-Q-wave UMI was modest (8%+/-7% of left ventricular mass, and left ventricular ejection fraction (LVEF by cine-CMR was usually preserved (52%+/-18%. The prevalence of non-Q-wave UMI increased with the extent and severity of coronary disease on angiography (p<0.0001 for both. Over 2.2 y (interquartile range 1.8-2.7, 16 deaths occurred: 13 in non-Q-wave UMI patients (26%, one in Q-wave UMI (7%, and two in patients without MI (2%. Multivariable analysis including New York Heart Association class and LVEF demonstrated that non-Q-wave UMI was an independent predictor of all-cause mortality (hazard ratio [HR] 11.4, 95% confidence interval [CI] 2

    More than 60 prospective cohort studies have shown a consistent association between regular and moderate alcohol consumption and decrease in risk of coronary heart disease, ischemic stroke and heart failure by 20 to 40% as compared to heavy alcohol intake or drinking no alcohol. Lower protective effects were found in young, in women and in men living outside the Mediterranean area. Moreover, some biological characteristics of alcohol, particularly red wine, could interfere with the athero-thrombotic process and contribute to increase the plausibility for the protective effects of alcohol on cardiovascular diseases. However, the results of meta-analyses also demonstrate harmful effects in relation with dose and pattern of alcohol consumption. In regard to the available scientific data, alcohol consumption cannot be include in the recommendations for the prevention of cardiovascular diseases. On the other hand alcohol should not be prohibited when consumption remains mild to moderate.

    2016-01-01

    Full Text Available The case illustrates the possible link between coronary spasms, intraluminal thrombus formation, and widespread organized and layered thrombi in HTx patients. Furthermore, the case underlines the clinical value of OCT as a novel method for high-resolution vessel imaging in heart-transplanted (HTx patients with coronary spasms and suspected coronary artery disease. Coronary spasms and sudden death are frequent complications after HTx. The underlying mechanisms leading to these complications are unknown. The present case displays the clinical course of a 19-year-old HTx patient who was hospitalized due to acute myocardial infarction induced by severe coronary spasms. The patients remained unstable on conservative therapy. Therefore, an optical coherence tomography (OCT was performed and revealed massive, organized thrombi in the left main coronary artery, the circumflex coronary artery, and the left anterior descending coronary artery. The patient was stabilized after percutaneous coronary intervention. As a mural thrombus often goes undetected by coronary angiography, OCT may prove benefit in HTx patients with myocardial infarction or suspected coronary spasms.

    Physicians rely upon chest pain history to make management decisions in patients with suspected acute coronary syndromes, particularly where the diagnosis is not immediately apparent through electrocardiography and troponin testing. The objective of this study was to establish the discriminatory value of "typicality of chest pain" and the effect of clinician experience, for the prediction of acute myocardial infarction and presence of significant coronary artery disease. This prospective single-center observational study was undertaken in a UK General Hospital emergency department. We recruited consecutive adults with chest pain and a nondiagnostic electrocardiogram, for whom the treating physician determined that delayed troponin testing was necessary. Using their own clinical judgment, physicians recorded whether the chest pain described was typical or atypical for acute coronary syndrome. Physicians were defined as "experienced" or "novice" according to postgraduate experience. Acute myocardial infarction was adjudicated using a high-sensitivity troponin (hs-cTn) assay, whereas coronary artery disease was adjudicated angiographically. Overall, 912 patients had typicality of chest pain assessed, of whom 114/912 (12.5%) had an acute myocardial infarction and 157/912 (17.2%) underwent angiography. In patients undergoing angiography, 90/157 (57.3%) had hs-cTn elevation, of whom 60 (66.7%) had significant coronary artery disease. Sixty-seven of 157 (42.7%) patients had angiography without hs-cTn elevation; of these, 31 (46.2%) had significant coronary artery disease. For the diagnosis of acute myocardial infarction, chest pain typicality had an area under the curve (AUC) of 0.54 (95% confidence interval [CI], 0.49-0.60). For the prediction of significant coronary artery disease with hs-cTn elevation AUC: 0.54 (95% CI, 0.40-0.67), and without hs-cTn elevation AUC: 0.45 (95% CI, 0.31-0.59). When assessed by experienced physicians, specificity for the diagnosis of acute

    Full Text Available Background. Acute coronary syndrome (ACS can complicate acute ischemic stroke, causing significant morbidity and mortality. To date, literatures that describe poststroke acute coronary syndrome and its morbidity and mortality burden are lacking. Methods. This is a single center, retrospective study where clinical characteristics, cardiac evaluation, and management of patients with suspected poststroke ACS were compared and analyzed for their association with inpatient mortality and 1-year all-cause mortality. Results. Of the 82 patients, 32% had chest pain and 88% had ischemic ECG changes; mean peak troponin level was 18, and mean ejection fraction was 40%. The medical management group had older individuals (73 versus 67 years, p<0.05, lower mean peak troponin levels (12 versus 49, p<0.05, and lower mean length of stay (12 versus 25 days, p<0.05 compared to those who underwent stent or CABG. Troponin levels were significantly associated with 1-year all-cause mortality. Conclusion. Age and troponin level appear to play a role in the current clinical decision making for patient with suspected poststroke ACS. Troponin level appears to significantly correlate with 1-year all-cause mortality. In the management of poststroke acute coronary syndrome, optimal medical therapy had similar inpatient and all-cause mortality compared to PCI and/or CABG.

    A 69-year-old woman was admitted for further examinations and treatment of chest pain. Emergency cardiac catheterization showed no significant stenosis on coronary angiograms; however, diffuse wall hypokinesis was observed on a left ventriculogram. After treating the patient's heart failure, cardiac catheterization was performed again. A spasm provocation test showed coronary spasms of the right and left coronary arteries. A right ventricular endomyocardial biopsy revealed denaturation and fibrosis of the myocardium under the endocardium, thus suggesting the presence of myocardial ischemia. This case highlights coronary spasms as a cause of heart failure.

    Approximately 20% of patients with coronary heart disease (CHD) have major depression and 20% have minor depression at any given point in the course of their illness. Depression causes significant psychological and social morbidity, and is a risk factor for further cardiac morbidity and mortality. Although there are many possible biological and behavioral mechanisms, the causal pathways through which depression increases the risk for cardiac events and death are not well understood. Despite the morbidity associated with depression, and the devastating impact it has on the quality of life of patients with CHD, it is underdiagnosed and often left untreated. This article describes screening techniques for use in primary care and cardiology settings, and discusses the safety and efficacy of available treatments for depression in patients with CHD.

    Coronary heart disease (CHD) is currently the leading cause of death worldwide and together with diabetes, poses a serious health threat, particularly in the Indian Asian population. Risk factor management has evolved considerably with the continued emergence of new and thought-provoking evidence. The stream of laboratory- and population-based research findings as well as unresolved controversies may pose dilemmas and conflicting impulses in most clinicians, and even in our more well-informed patients. As results of the most recent clinical trials on glycaemic control for macrovascular risk reduction are woven into concrete clinical practice guidelines, this paper seeks to sort through unwieldy evidence, keeping these findings in perspective, to deliver a clearer message for the context of South Asia and cardio-metabolic risk management.

    Increased serum triglyceride and apolipoprotein B (apoB) levels and decreased high-density lipoprotein cholesterol (HDL-C) levels are risk factors for cardiovascular diseases. The major types of dyslipidemia in Chinese population are hypertriglyceridemia and low HDL-C. This study aimed to evaluate the effect of HDL-C, triglyceride, and apoB levels on the risk of coronary heart disease (CHD) in a Chinese population undergoing coronary angiography. This was a cross-sectional study. A total of 1941 consecutive patients who were referred to coronary angiography for the evaluation of suspected CHD were recruited. Lipid parameters were measured after an overnight fast. Patients were diagnosed with CHD and without CHD based on the findings of the coronary angiography. There were 1363 angiography confirmed CHD patients and 578 non-CHD patients. In nonstatin users, the major types of dyslipidemia were hypertriglyceridemia combined with low HDL-C, isolated low HDL-C, and isolated hypertriglyceridemia, accounting for 21.60%, 19.70%, and 14.99%, respectively. In statin users, a low to moderate-intensity statin was effective in lowering low-density lipoprotein cholesterol (LDL-C). The proportion of reaching an LDL-C goal coronary angiography with a relatively low level of LDL-C and a high prevalence of hypertriglyceridemia and low HDL-C.

    In 2003, the National Heart Foundation of Australia published a position statement on psychosocial risk factors and coronary heart disease (CHD). This consensus statement provides an updated review of the literature on psychosocial stressors, including chronic stressors (in particular, work stress), acute individual stressors and acute population stressors, to guide health professionals based on current evidence. It complements a separate updated statement on depression and CHD. Perceived chronic job strain and shift work are associated with a small absolute increased risk of developing CHD, but there is limited evidence regarding their effect on the prognosis of CHD. Evidence regarding a relationship between CHD and job (in)security, job satisfaction, working hours, effort-reward imbalance and job loss is inconclusive. Expert consensus is that workplace programs aimed at weight loss, exercise and other standard cardiovascular risk factors may have positive outcomes for these risk factors, but no evidence is available regarding the effect of such programs on the development of CHD. Social isolation after myocardial infarction (MI) is associated with an adverse prognosis. Expert consensus is that although measures to reduce social isolation are likely to produce positive psychosocial effects, it is unclear whether this would also improve CHD outcomes. Acute emotional stress may trigger MI or takotsubo ("stress") cardiomyopathy, but the absolute increase in transient risk from an individual stressor is low. Psychosocial stressors have an impact on CHD, but clinical significance and prevention require further study. Awareness of the potential for increased cardiovascular risk among populations exposed to natural disasters and other conditions of extreme stress may be useful for emergency services response planning. Wider public access to defibrillators should be available where large populations gather, such as sporting venues and airports, and as part of the response

  17. A genetic future for coronary heart disease?

    Science.gov (United States)

    Weiner, Kate; Martin, Paul

    2008-04-01

    This paper is concerned with changing conceptions of genetic disease. It is based on an analysis of biomedical literature and focuses on the treatment of coronary heart disease (CHD) in four published commentary papers. The aim of this analysis is to explore the ways in which CHD is constructed as genetic and the place of genetic discourses in the wider set of ideas that circulate about the disease. This analysis is then used to consider some of the claims of the geneticisation thesis (Lippman 1991, 1992). The analysis suggests that a genetic vision for understanding and managing CHD has emerged, which has many of the hallmarks of the geneticisation imagined by Lippman. However, a number of alternative and competing models of CHD are also supported within the biomedical discourse. These are related to the different disciplines with a stake in the field of CHD, and their struggles for authority. In conclusion, it is suggested that the geneticisation thesis, as a universal claim, is at odds with the diffuse and distributed nature of biomedical knowledge and practice. Rather than analysing geneticisation in a literal way, it may be more fruitful to see the thesis, itself, as a form of boundary work (Gieryn 1983).

    A high-cholesterol diet has been associated with an increased risk of coronary heart disease, but it is unclear whether all high-cholesterol foods increase the risk of heart disease. The purpose of this study is to determine whether shellfish consumption is associated with an increased risk of coronary heart disease. Analysis was performed on the Atherosclerosis Risk in Communities study, a cohort of middle aged and elderly adults in the United States. The association between reported shellfish consumption to the development of coronary heart disease was examined. The cohort was divided into low, medium, and high shellfish consumers. There were 13,355 participants meeting our inclusion criteria, of which 1,382 suffered a coronary heart disease event. Using low shellfish consumers as the reference group, the medium shellfish consumers had an unadjusted hazard ratio of 0.89 (95% confidence interval [CI] 0.79 to 1.00), and the high shellfish consumers had an unadjusted hazard ratio of 0.91 (95% CI 0.80 to 1.03) of suffering a coronary heart disease event. In a model that was adjusted for age, sex, race, smoking status, body mass index, diabetes, hypertension, low-density lipoprotein cholesterol level, high-density lipoprotein cholesterol level, family history of early heart disease, and exercise status using the low shellfish consumers as the reference group, medium shellfish consumers had a hazard ratio of 0.96 (95% CI 0.80 to 1.16), and the high shellfish consumers had a hazard ratio of 0.98 (95% CI 0.82 to 1.18) of experiencing a coronary heart disease event.

    Objective To examine associations between loneliness and risk of incident coronary heart disease (CHD) over a 19-year follow-up period in a community sample of men and women. Loneliness, the perceived discrepancy between actual and desired social relationships, has been linked to several adverse health outcomes. However, no previous research has prospectively examined the association between loneliness and incident CHD in a community sample of men and women. Methods Hypotheses were examined using data from the First National Health and Nutrition Survey and its follow-up studies (n = 3003). Loneliness, assessed by one item from the Center for Epidemiologic Studies of Depression scale, and covariates were derived from baseline interviews. Incident CHD was derived from hospital records/death certificates over 19 years of follow-up. Hypotheses were evaluated, using Cox proportional hazards models. Results Among women, high loneliness was associated with increased risk of incident CHD (high: hazard ratio = 1.76, 95% Confidence Interval = 1.17â2.63; medium: hazard ratio = 0.98, 95% Confidence Interval = 0.64â1.49; reference: low), controlling for age, race, education, income, marital status, hypertension, diabetes, cholesterol, physical activity, smoking, alcohol use, systolic and diastolic blood pressures, and body mass index. Findings persisted additionally controlling for depressive symptoms. No significant associations were observed among men. Conclusions Loneliness was prospectively associated with increased risk of incident CHD, controlling for multiple confounding factors. Loneliness among women may merit clinical attention, not only due to its impact on quality of life but also its potential implications for cardiovascular health. PMID:19661189

    Identifying patients with obstructive coronary artery disease can be challenging for primary care physicians. Advances in precision medicine may help augment clinical tools and redefine the paradigm for evaluating coronary artery disease in the outpatient setting. A blood-based age/sex/gene expression score (ASGES) incorporating key features of precision medicine has shown clinical validity with a 96% negative predictive value and 89% sensitivity in estimating a symptomatic patient's current likelihood of obstructive coronary artery disease. To better characterize the clinical utility of the ASGES and measure its impact on clinician decision-making, a community-based registry was established. The prospective PRESET Registry (NCT01677156) enrolled stable, nonacute adult patients presenting with typical or atypical symptoms suggestive of obstructive coronary artery disease from 21 US primary care practices from August 2012 to August 2014. Demographics, clinical characteristics, and ASGES results (predefined as low [ASGES ≤15] or elevated [ASGES >15]) were collected, as were referrals to Cardiology or further functional/anatomic cardiac testing after ASGES testing. Patients were followed for 1 year post ASGES testing. Among the 566-patient cohort (median age 56 years), clinicians referred 26/252 (10%) of patients with low scores vs 137/314 (44%) of patients with elevated scores to Cardiology or advanced cardiac testing for further evaluation (unadjusted odds ratio 0.15, P clinical covariates = 0.18, P advanced cardiac testing showed abnormal findings in 0 of 13 (0%) low ASGES and 10 of 71 (14%) elevated ASGES patients. Major adverse cardiovascular events and revascularization were noted in 3/252 (1.2%) patients with low ASGES and 14/314 (4.5%) patients with elevated ASGES score (P clinical utility in the evaluation of patients with suspected obstructive coronary artery disease.

    Increased body mass index (BMI) has been paradoxically inversely associated with the presence of angiographic coronary artery disease (CAD). Central obesity measures, considered to be more appropriate for assessing obesity-related cardiovascular risk, have been little studied in relation to the presence of CAD. The aim was to investigate the association of central obesity with the presence of angiographic CAD as well as the prognostic significance of obesity measures in CAD prediction when added to other cardiovascular risk factors. Patients with suspected stable CAD (n = 403, age 61 ± 10 years, 302 males) referred for diagnostic coronary angiography with documented anthropometric data were enrolled. Significant angiographic CAD was found in 51% of patients. Both BMI (OR = 0.64 per 1 SD increase, P = 0.001) and waist circumference (WC) (OR = 0.54 per 1 SD increase, P cardiovascular risk factors. In subgroup analysis, BMI and WC were significantly inversely associated with the presence of CAD in males, non diabetics, patients >60 years old and patients with Framingham risk score (FRS) >20% (P obesity were independently associated with a reduced prevalence of angiographic CAD, lending further credence to the existence of the 'obesity paradox'. Obesity measures may further improve risk discrimination for the presence of CAD when added in an established risk score such as FRS. Copyright © 2013 The Obesity Society.

    To establish standardized methods and parameters of the isolated heart coronary angiography through the experiment of in vitro porcine heart by MSCT. Based on different perfusion volume (50, 60 and 70 mL) and different perfusion-imaging time (5, 10 and 20 min), the in vitro porcine coronary artery was injected liposoluble and water-soluble contrast agents using remodel angiography equipment and scanned by MSCT. And the 3D image results were compared. The images were recorded and evaluated by 2 radiologists and analyzed by statistical software. Liposoluble contrast agent affected the images by damaging and infiltrating the fats around the coronary artery, while the water-soluble contrast agent didn't affect the images. The groups with 60 mL or 70 mL perfusion and 5 min perfusion-imaging time had the best images. The suitable parameters of the angiography lay the foundation of postmortem coronary angiography.

    The objectives of this study were to develop a coronary heart disease (CHD) risk model among the Korean Heart Study (KHS) population and compare it with the Framingham CHD risk score. A prospective cohort study within a national insurance system. 18 health promotion centres nationwide between 1996 and 2001 in Korea. 268 315 Koreans between the ages of 30 and 74 years without CHD at baseline. Non-fatal or fatal CHD events between 1997 and 2011. During an 11.6-year median follow-up, 2596 CHD events (1903 non-fatal and 693 fatal) occurred in the cohort. The optimal CHD model was created by adding high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol and triglycerides to the basic CHD model, evaluating using the area under the receiver operating characteristic curve (ROC) and continuous net reclassification index (NRI). The optimal CHD models for men and women included HDL-cholesterol (NRI=0.284) and triglycerides (NRI=0.207) from the basic CHD model, respectively. The discrimination using the CHD model in the Korean cohort was high: the areas under ROC were 0.764 (95% CI 0.752 to 0.774) for men and 0.815 (95% CI 0.795 to 0.835) for women. The Framingham risk function predicted 3-6 times as many CHD events than observed. Recalibration of the Framingham function using the mean values of risk factors and mean CHD incidence rates of the KHS cohort substantially improved the performance of the Framingham functions in the KHS cohort. The present study provides the first evidence that the Framingham risk function overestimates the risk of CHD in the Korean population where CHD incidence is low. The Korean CHD risk model is well-calculated alternations which can be used to predict an individual's risk of CHD and provides a useful guide to identify the groups at high risk for CHD among Koreans.

    To evaluate the accuracy of low-dose coronary CTA with iterative reconstruction (IR) in the diagnosis of coronary artery disease (CAD) in patients with suspected CAD. Ninety-six patients with suspected CAD underwent low-dose prospective electrocardiogram-gated coronary CTA, with images reconstructed using IR. Image quality (IQ) of coronary segments were graded on a 4-point scale (4, excellent; 1, non-diagnostic). With invasive coronary angiography (ICA) considered the ''gold standard'', the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of coronary CTA were calculated on segment-, vessel- and patient-based levels. The patient data were divided into two groups (Agatston scores of ≥ 400 and <400). The differences in diagnostic performance between the two groups were tested. Diagnostic image quality was found in 98.1 % (1,232/1,256) of segments. The sensitivity, specificity, PPV, NPV and accuracy were 90.8 %, 95.3 %, 81.8 %, 97.8 % and 94.3 % (segment-based) and 97.2 %, 83.3 %, 94.6 %, 90.9 % and 93.8 % (patient-based). Significant differences between the two groups were seen in specificity, PPV and accuracy (92.1 % vs. 97.9 %, 76.0 % vs. 86.7 %, 91.7 % vs. 96.6 %, P < 0.05; segment-based). The average effective dose was 1.30 ± 0.15 mSv. Low-dose prospective coronary CTA with IR can acquire satisfactory image quality and show high diagnostic accuracy in patients with suspected CAD; however, blooming continues to pose a challenge in severely calcified segments.

    2009-12-01

    To review randomized control clinical trial (RCT) literature and prospective studies for the safety and efficacy of magnesium supplements in patients with coronary heart disease (CHD) or with CHD risk. Databases were searched using the keywords: magnesium, heart disease, endothelium, prevention, treatment, therapy, level, and supplement. There were no reports of adverse effects from magnesium supplementation in any of the studies. Subjects reporting lower dietary magnesium intake had significantly lower serum magnesium concentrations than those reporting higher dietary magnesium intake and, in some cases, had a significantly higher frequency of supraventricular beats. There was a modest relationship between dietary magnesium intake and a reduced risk of CHD in male subjects; however, there was no noted decrease in the development of CHD disease in women who had high magnesium intake. Magnesium is vital for many functions in the body and magnesium supplementation is safe. There is a possible association between a modestly lower risk of CHD in men and increased magnesium intake; therefore, it is reasonable to encourage diets high in magnesium as a potential means to lower the risk of CHD.

    Obesity is key feature of the metabolic syndrome and is associated with high cardiovascular morbidity and mortality. Obesity is associated with macrovascular endothelial dysfunction, a determinant of outcome in patients with coronary artery disease. Here, we compared the influence of obesity on microvascular endothelial function to that of established cardiovascular risk factors such as diabetes mellitus, hypertension, hypercholesterolemia, and smoking in patients with suspected coronary artery disease. Endothelial function was assessed during postocclusive reactive hyperemia of the brachial artery and downstream microvascular beds in 108 patients who were scheduled for coronary angiography. In all patients, microvascular vasodilation was assessed using peripheral arterial tonometry; laser Doppler flowmetry and digital thermal monitoring were performed. Body mass index was significantly associated with decreased endothelium-dependent vasodilatation measured with peripheral arterial tonometry (r=0.23, P=0.02), laser Doppler flowmetry (r=0.30, Pmicrovascular vasodilatation. Especially in diabetic patients, endothelial function was not significantly reduced (control versus diabetes mellitus, mean±SEM or median [interquartile range], peripheral arterial tonometry: 1.90±0.20 versus 1.67±0.20, P=0.19, laser Doppler flowmetry: 728% [interquartile range, 427-1110] versus 589% [interquartile range, 320-1067] P=0.28, and digital thermal monitoring: 6.6±1.0% versus 2.5±1.7%, P=0.08). In multivariate linear regression analysis, body mass index was the only risk factor that significantly attenuated endothelium-dependent vasodilatation using all 3 microvascular function tests. Higher body mass index is associated with reduced endothelial function in patients with suspected coronary artery disease, even after adjustment for treated diabetes mellitus, hypertension, hypercholesterolemia, and smoking. © 2017 The Authors.

    We examined the performance of a familial risk assessment method that stratifies risk for early-onset coronary heart disease by considering the number of relatives with coronary disease, degree of relationship, lineage, and age at diagnosis. By using data from the HealthStyles 2003 survey, we assessed the associations between familial risk and early-onset coronary heart disease, diabetes, hypercholesterolemia, hypertension, and obesity. By using area under the curve statistics, we evaluated the discriminatory ability of various risk assessment models. Of 4,035 respondents, 60% were female and 72% were white, with a mean age of 48.8 years. After adjustment for demographics, strong and moderate risk were significantly associated with approximately a five- and twofold risk of early-onset coronary disease, respectively. After adjustment for demographics and personal history of cardiovascular disease, strong familial risk was also significantly associated with diabetes, hypercholesterolemia, hypertension, and obesity. A risk assessment model that included familial risk, demographics, and personal history of diabetes, hypercholesterolemia, hypertension, and obesity was most optimal with an area under the curve statistic of 87.2% Familial risk assessment can stratify risk for early-onset coronary heart disease. Several conditions associated with increased familial risk can be prevented. These results have important implications for risk assessment and risk-reducing interventions.

    The prevalence of a major depressive disorder in patients after myocardial infarction is 20%. Depression is a risk factor for incident coronary heart disease and poor prognosis after myocardial infarction. Poor lifestyle habits and adherence to cardiac therapy as well as metabolic and pathophysiologic changes may partially explain this link. The threatening experience of an acute coronary event and immune and inflammatory changes may be unique features contributing to incident depression after myocardial infarction. While psychotherapy, antidepressants, and physical exercise may alleviate depressive symptoms in patients with coronary heart disease, cardiac rehabilitation additionally reduces mortality risk. Attempts are being undertaken to identify the cardiotoxic characteristics of depression to develop even more effective therapies in the future.

  8. The clinical role of stress myocardial perfusion imaging in women with suspected coronary artery disease.

    2004-01-01

    Cardiovascular disease remains the number one cause of mortality for women in the United States, with coronary artery disease (CAD) accounting for 54% of all cardiovascular deaths. CAD claims the lives of more than 250,000 women each year and is therefore the single largest killer of American women. For several decades, the under-representation of women in clinical trials led to both a lack of available sex-specific evidence and a generalized misconception that CAD was a "man's disease." In actuality, not only are women vulnerable to CAD, they typically develop it 10 to 15 years later than men. Furthermore, sex differences exist in the mortality rates of women and men with CAD, such that once CAD is present in women, they have worse outcomes than their male counterparts. Consequently, early and accurate diagnosis of CAD is crucial for reducing mortality rates in women. Stress myocardial perfusion imaging (MPI) using contemporary techniques has been shown to have significant value in the diagnosis and prognosis of CAD in women. In the risk assessment of women with an intermediate clinical pretest likelihood of CAD, using MPI with exercise or pharmacologic stress has been shown to add incremental value to clinical variables or exercise electrocardiogram stress testing alone. This review discusses the clinical role of stress MPI in the management of women with suspected CAD.

    To implement a high-resolution first-pass myocardial perfusion imaging protocol (HRPI) at 3 T, and to evaluate the feasibility, image quality and accuracy of this approach prospectively in patients with suspected CAD. We hypothesized that utilizing the gain in SNR at 3 T to increase spatial resolution would reduce partial volume effects and subendocardial dark rim artifacts in comparison to 1.5 T. HRPI studies were performed on 60 patients using a segmented k-space gradient echo sequence (in plane resolution 1.97 x 1.94 mm{sup 2}). Semiquantitative assessment of dark rim artifacts was performed for the stress studies on a slice-by-slice basis. Qualitative visual analysis was compared to quantitative coronary angiography (QCA) results; hemodynamically significant CAD was defined as stenosis {>=}70% at QCA. Dark rim artifacts appeared in 108 of 180 slices (average extent 1.3 {+-} 1.2 mm representing 11.8 {+-} 10.8% of the transmural myocardial thickness). Sensitivity, specifity, and test accuracy for the detection of significant CAD were 89%,79%, and 85%. HRPI studies at 3 T are feasible in a clinical setting, providing good image quality and high accuracy for detection of significant CAD. The presence of dark rim artifacts does not appear to represent a diagnostic problem when using a HRPI approach. (orig.)

    Lipid profile management is even more critical in patients treated for secondary prevention, since patients with established coronary heart disease are at higher risk of developing events. Current guidelines encourage lifestyle modification and patient engagement in disease prevention. However, the American College of Cardiology/American Heart Association guidelines seem to differ considerably from their predecessors, having an impact on clinical practice of lipid management. Area covered: This review article discusses and provides a summary of the current recommendations for lipid profile management in patients with coronary heart disease, with a view to present lifestyle modification and novel treatment strategies, and to indicate areas of dispute among recent guidelines. Expert commentary: Existing controversies between current guidelines concerning treatment goals and therapeutic decisions may have potential implications on the clinical management of patients. In the meantime, we eagerly wait for the results of randomized controlled trials evaluating promising, potent, safe and prolonged drugs that are in progress.

    Multiple coronary artery aneurysms, rarely seen in patients with atherosclerotic heart disease, can be frequently observed in children with Kawasaki disease. However, their long-term clinical courses still remain obscure. A thirty-nine-year-old male came to our clinic because of congestive heart failure. A left ventriculogram revealed highly reduced wall motion. A coronary angiogram showed left main trunk aneurysm with complete occlusion of the left anterior descending artery and ramification of the right coronary artery close to the ostium. Six months after discharge, he died suddenly. On autopsy, aneurysms were observed in the left main trunk and right coronary artery, together with an old anteroseptal myocardial infarction. Although he did not have a clear history of febrile disease in childhood, he was highly suspected to be a long-term survivor of Kawasaki disease because of the unique form and distribution of the coronary artery aneurysms.

    Multislice computed tomographic coronary angiography (CTCA) provides accurate noninvasive assessment of coronary artery disease (CAD). However, data on the prognostic value of CTCA in patients with suspected CAD are only beginning to emerge. The aim of the study was to assess the prognostic value of CTCA in patients with suspected CAD. Patients (males = 259, females = 235; mean age 58.2 ± 9.8 years) with suspected CAD who underwent 16- or 64-slice CTCA were followed for 1,308 ± 318 days for cardiac death, nonfatal myocaridal infarction (MI) and late (>90 days after CTCA) revascularization. Patient outcomes were related to clinical and CTCA data. Cox proportional-hazards model was applied in stepwise forward fashion to identify outcome predictors. Coronary artery plaque was found in 340 patients. Cardiac events occurred in 40 patients including cardiac death (n = 9), nonfatal MI (n = 8) and late revascularization (n = 23). A multivariable analysis identified the following independent predictors for adverse cardiac events: obstructive plaque in a proximal coronary artery segment (hazard ratio (HR) 2.73; 95% confidence interval (CI): 1.35-5.54; P = 0.005), the number of segments with noncalcified plaque(s) (HR 1.53 per segment; 95%CI: 1.21-1.92; P < 0.001), the number of segments with mixed plaque(s) (HR 1.56 per segment; 95%CI: 1.27-1.92; P < 0.001) and the number of segments with calcified plaque(s) (HR 1.21 per segment; 95%CI: 1.07-1.37; P = 0.002). In patients with suspected CAD, both the extent and composition of atherosclerotic plaque as determined by CTCA are prognostic of subsequent cardiac events.

    We determined the efficiency of a screening protocol based on coronary calcium scores (CCS) compared with exercise testing in patients with suspected coronary artery disease (CAD), a normal ECG and troponin levels. Three-hundred-and-four patients were enrolled in a screening protocol including CCS by electron beam computed tomography (Agatston score), and exercise testing. Decision-making was based on CCS. When CCS{>=}400, coronary angiography (CAG) was recommended. When CCS<10, patients were discharged. Exercise tests were graded as positive, negative or nondiagnostic. The combined endpoint was defined as coronary event or obstructive CAD at CAG. During 12{+-}4 months, CCS{>=}400, 10-399 and <10 were found in 42, 103 and 159 patients and the combined endpoint occurred in 24 (57%), 14 (14%) and 0 patients (0%), respectively. In 22 patients (7%), myocardial perfusion scintigraphy was performed instead of exercise testing due to the inability to perform an exercise test. A positive, nondiagnostic and negative exercise test result was found in 37, 76 and 191 patients, and the combined endpoint occurred in 11 (30%), 15 (20%) and 12 patients (6%), respectively. Receiver-operator characteristics analysis showed that the area under the curve of 0.89 (95% CI: 0.85-0.93) for CCS was superior to 0.69 (95% CI: 0.61-0.78) for exercise testing (P<0.0001). In conclusion, measurement of CCS is an appropriate initial screening test in a well-defined low-risk population with suspected CAD. (orig.)

A variety of causes, including donor heart characteristics, recipient risk factors, and immune-mediated influences, are associated with developing CAV. In this review, we will focus on the pathophysiology of developing CAV and various methods to screen for this condition. The pathogenesis of CAV likely involves repeated injuries to the endothelium from a variety of factors such as cellular-mediated rejection, and alloimmune factors, including antibody-mediated injury, ischemia-reperfusion injury at time of transplant, cytomegalovirus infections, immunosuppression medications, systemic inflammation, and traditional atherosclerosis risk factors. Patients with significant CAV are often asymptomatic, and therefore early detection by routine screening prior to graft dysfunction is crucial. There are a variety of invasive, noninvasive, and blood tests that have been studied as screening methods, and we will discuss the role of each of these in this review article. Although some treatment regimens have been established for CAV, this is an area where further studies and research are necessary.Keywords: cardiac allograft vasculopathy, orthotopic heart transplantation, intra-vascular imaging

    Phase-contrast (PC) cine magnetic resonance imaging (MRI) of the coronary sinus is a noninvasive method to quantify coronary flow reserve (CFR). This study sought to compare the prognostic value of CFR by cardiac magnetic resonance (CMR) and stress perfusion CMR to predict major adverse cardiac events (MACE). Participants included 276 patients with known coronary artery disease (CAD) and 400 with suspected CAD. CFR was calculated as myocardial blood flow during adenosine triphosphate infusion divided by myocardial blood flow at rest using PC cine MRI of the coronary sinus. During a median follow-up of 2.3 years, 47 patients (7%) experienced MACE. Impaired CFR (10% ischemia on stress perfusion CMR were significantly associated with MACE in patients with known CAD (hazard ratio [HR]: 5.17 and HR: 5.10, respectively) and suspected CAD (HR: 14.16 and HR: 6.50, respectively). The area under the curve for predicting MACE was 0.773 for CFR and 0.731 for stress perfusion CMR (p = 0.58) for patients with known CAD, and 0.885 for CFR and 0.776 for stress perfusion CMR (p = 0.059) in the group with suspected CAD. In patients with known CAD, sensitivity, specificity, and positive and negative predictive values to predict MACE were 64%, 91%, 38%, and 97%, respectively, for CFR, and 82%, 59%, 15%, and 97%, respectively, for stress perfusion CMR. In the suspected CAD group, these values were 65%, 99%, 80%, and 97%, respectively, for CFR, and 72%, 83%, 22%, and 98%, respectively, for stress perfusion CMR. The predictive values of CFR and stress perfusion CMR for MACE were comparable in patients with known CAD. In patients with suspected CAD, CFR showed higher HRs and areas under the curve than stress perfusion CMR, suggesting that CFR assessment by PC cine MRI might provide better risk stratification for patients with suspected CAD.

    Among patients with acute chest pain, acute coronary syndrome (ACS) is seen only in a minority of the patients, which raises the question, whether it is possible to separate a group with a high risk of ACS for admission to a cardiac care unit (CCU) from those with a low risk who would be treated at an emergency department (ED). The aim of this study was to describe a risk stratification model for a Danish context. This was a historic prospective cohort study of patients with suspicion of ACS. The patient was defined as a low-risk patient and admitted to the ED if: 1) electrocardiogram (ECG) was normal, 2) the patient did not have persisting chest pain and 3) there was no history of ischaemic heart disease, heart failure or cardioverter defibrillator. Otherwise, patients were admitted to the CCU. The primary outcome was whether the ACS diagnosis was confirmed or rejected. We included a total of 488 patients with suspicion of ACS, 50% of whom were low-risk patients. 17% had a verified ACS; 10% of those in the low-risk group and 24% of those in the high-risk group (p = 0.0001). Among the verified ACS cases, 71% went primarily to the CCU. The odds ratio for an ACS if assigned to the high-risk group was 3.0. Allocation to the high-risk group, male gender and age above 60 years was associated with a higher risk of ACS. For patients fulfilling the high-risk definition, sensitivity was 71%, specificity 55%, negative predictive value 90% and positive predictive value 24% for an ACS. The model for stratification separated patients into two equal groups, allocated 71% of all ACS directly to the CCU and could not be improved by any of the additional factors examined. Further development of referral strategies for chest pain patients is required. none. not relevant.

    Full Text Available Abstract Introduction There is a strong clinical need to provide effective stress reduction programs for patients with an acute coronary syndrome. Such programs for men have been implemented and their cardiovascular health benefit documented. For women such programs are scarce. In this report, The feasibility of a cognitive method that was recently demonstrated to prolong lives of women is tested. A setting with gender segregated groups was applied. Method The principles of a behavioural health educational program originally designed to attenuate the stress of patients with coronary prone behaviours were used as a basis for the intervention method. For the groups of female patients this method was tailored according to female stressors and for the groups of men according to male stressors. The same core stress reduction program was used for women and men, but the contents of discussions and responses to the pre planned program varied. These were continuously monitored throughout the fifteen sessions. Implementation group: Thirty consecutive patients, eleven women and nineteen men, hospitalized for an acute coronary syndrome were included in this intervention. All expressed their need to learn how to cope with stress in daily life and were highly motivated. Five groups, three groups of men and two groups of women were formed. Psychological assessments were made immediately before and after completion of the program. Results No gender differences in the pre planned programs were found, but discussion styles varied between the women and men, Women were more open and more personal. Family issues were more frequent than job issues, although all women were employed outside their homes. Men talked about concrete and practical things, mostly about their jobs, and not directly about their feelings. Daily stresses of life decreased significantly for both men and women, but more so for women. Depressive thoughts were low at baseline, and there was no

    The objective of this study is to study the involvement of anxiety/depression in patients with coronary heart disease after percutaneous coronary intervention. Inpatients in the Department of Cardiology of Xuzhou Center Hospital from December 2012 to July 2014 were divided into stent group (100 cases) and the non-stent group (50 cases). Fifty cases in the stent group were treated with psychological methods, called intervention group, and other 50 cases were untreated and called non-intervention group. All patients were assessed for anxiety and depression using self-rating anxiety scale and self-rating depression scale, 1 day after admission, 1 day after coronary angiography, and when they were discharged. No significant differences were observed on biochemical criterion, and anxiety scores or depression scores between the stent and the non-stent groups before percutaneous coronary intervention (P value >0.05 for all). After percutaneous coronary intervention, anxiety/depression scores in the intervention group and non-intervention group were significantly higher than those in the non-stent group (P anxiety/depression scores (P > 0.05). On the day of discharge, the anxiety/depression scores were the lowest in the intervention group (P Coronary artery intervention can increase patients' anxiety/depression, but appropriate psychological intervention can reduce the negative emotions.

    Shift and night work are among the most frequent occupational exposures. Such work schedules involve exposure to light-at-night, which may reduce normal nocturnal melatonin production, create circadian rhythm disruption, sleep deprivation and unhealthy lifestyle. There is strong experimental evidence that light-at-night and circadian disruption may increase the risk of cancer and coronary heart diseases. There is emerging, but limited epidemiologic evidence that night shift work may increase breast cancer and certain cardiovascular diseases.

    Sleep deprivation (SD) has been associated with an increased morbidity and mortality of coronary heart disease (CHD). SD could induce autonomic nervous dysfunction, hypertension, arrhythmia, hormonal dysregulation, oxidative stress, endothelial dysfunction, inflammation and metabolic disorder in CHD patients. This paper reviewed the study results of SD in clinical trials and animal experiments and concluded that SD was associated with cardiovascular risk factors, which aggravated CHD in pathogenesis and outcomes.

    To evaluate the efficiency and safety of emergency department (ED) coronary computed tomography angiography (CTA) during a 3-year clinical experience. Single-center registry of coronary CTA in consecutive ED patients with suspicion of acute coronary syndrome (ACS). The primary outcome was efficiency of coronary CTA defined as the length of hospitalization. Secondary endpoints of safety were defined as the rate of downstream testing, normalcy rates of invasive coronary angiography (ICA), absence of missed ACS, and major adverse cardiac events (MACE) during follow-up, and index radiation exposure. One thousand twenty two consecutive patients were referred for clinical coronary CTA with suspicion of ACS. Overall, median time to discharge home was 10.5 (5.7-24.1) hours. Patient disposition was 42.7 % direct discharge from the ED, 43.2 % discharge from emergency unit, and 14.1 % hospital admission. ACS rate during index hospitalization was 9.1 %. One hundred ninety two patients underwent additional diagnostic imaging and 77 underwent ICA. The positive predictive value of CTA compared to ICA was 78.9 % (95 %-CI 68.1-87.5 %). Median CT radiation exposure was 4.0 (2.5-5.8) mSv. No ACS was missed; MACE at follow-up after negative CTA was 0.2 %. Coronary CTA in an experienced tertiary care setting allows for efficient and safe management of patients with suspicion for ACS. (orig.)

However, the relationship between serum calcium and coronary heart disease is unclear. The purpose of this study was to compare serum calcium levels in patients with coronary heart disease and those in healthy individuals. Methods: This retrospective, case-control study conducted in the People's Republic of China comprised 380 cases and 379 controls. Serum calcium levels, blood lipids, and anthropometric measurements were measured in both groups. The Student's unpaired t-test or Chi-square test was used to compare differences between cases and controls. Pearson's partial correlation coefficient was used to determine the association between serum calcium, blood lipids, and blood pressure in both groups. Results: Our results indicate that the average level of serum calcium in cases was higher than in controls. Serum calcium levels showed no correlation with any parameter except for triglycerides in either group. Conclusion: Overall, these data suggest that serum calcium has no influence on coronary heart disease or triglyceride levels in the general population. Keywords: serum calcium, hypertension, blood lipids

    Aim of the present study was to determine the prevalence of coronary artery anomalies in children with congenital heart disease. Data of 1138 consecutive patients who were referred for cardiac catheterization and angiography for assessment of coronary anomaly between January 2005 and December 2009 were retrospectively analyzed. Total of 515 patients whose coronary arteries could be examined through left ventricle and aortic root injection were included in the study. Of 515 angiograms with visible coronaries, 42 patients (20 males, 22 females; mean age: 5.3±2.0 years) were found to have final diagnosis of coronary anomaly. Prevalence of coronary artery anomalies was 8.16% in this study. It was determined that 38 (90.4%) were anomalies of origination, 2 (4.8%) were anomalies of intrinsic coronary arterial anatomy, and 2 (4.8%) were anomalies of coronary termination. Most common coronary artery abnormality was anomalous origin of the right coronary artery from the left aortic sinus (16 patients; 38.1%), and the most common congenital heart disease was tetralogy of Fallot (18 patients; 42.9%). Recognizing variability of coronary artery anomalies is critical when considering surgical or interventional therapies in children with congenital heart disease.

    Aim: To describe and evaluate anatomical characterizations of incidental left atrial (LA) diverticula in patients with suspected coronary artery disease using 64-channel multidetector computed tomography (MDCT). Materials and methods: From October 2008 to June 2009, 2059 patients with suspected coronary artery disease underwent electrocardiogram-gated 64-channel MDCT. Five hundred and thirty-two LA diverticula were identified in 377 patients (18.3%, male to female ratio: 216:161, mean age 59 {+-} 10.89 years, range from 20 to 91 years). Two radiologists retrospectively analysed the number (single or multiple), size (diameter and length), shape (cystiform or tubiform), surface (smooth or irregular), and location (right or mid or left/upper or lower/lateral or posterior). If the length/diameter was <1.5, the diverticular shape was considered to be cystiform. Results: Among 532 LA diverticula, single (270/532, 51.1%), cystiform (411/532, 77.3%), and smooth (332/532, 62.4%) diverticula were found. The right upper region (255/532, 47.9%) was the most common location, followed by the left lateral area (172/532, 32.3%). The average diameter was 4.7 {+-} 2 mm (range from 1-19 mm), and the average length was 4.7 {+-} 2.1 mm (range 1-13 mm). The average ratio of length to diameter was 1.15 (range 0.25-1.45). The average number of diverticula was 2 {+-} 1.06 (range 1-5). Conclusion: Incidental LA diverticulum is not an uncommon finding in patients with suspected coronary artery disease. MDCT can provide anatomical details of LA diverticula. However, further studies are needed to determine their clinical significance.

    Coronary heart disease and ischemic stroke are frequent coexistent conditions that share risk factors and pose major burdens to global health. Even though a clear relation has been established between extracranial internal carotid artery atherosclerosis and symptomatic or asymptomatic coronary heart disease, there is a gap in knowledge about the association between intracranial atherosclerosis and coronary heart disease. Intracranial atherosclerosis is associated with high risks of stroke recurrence and vascular death. More research and clinical trials are needed to answer whether early diagnosis of asymptomatic coronary heart disease and aggressive treatment can decrease the risk of vascular death in patients with ischemic stroke caused by intracranial atherosclerosis.

    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.

  20. Effects of bileaflet mechanical heart valve orientation on coronary flow

    2015-11-01

    The aortic sinus is approximately tri-radially symmetric, but bileaflet mechanical heart valves (BMHVs), which are commonly used to replace diseased aortic valves, are bilaterally symmetric. This mismatch in symmetry suggests that the orientation in which a BMHV is implanted within the aortic sinus affects the flow characteristics downstream of it. This study examines the effect of BMHV orientation on the flow in the coronary arteries, which originate in the aortic sinus and supply the heart tissue with blood. Planar particle image velocimetry measurements were made past a BMHV mounted at the inlet of an anatomical aorta model under physiological flow conditions. The complex interactions between the valve jets, the sinus vortex and the flow in the right coronary artery were elucidated for three valve orientations. The coronary flow rate was directly affected by the size, orientation, and time evolution of the vortex in the sinus, all of which were sensitive to the valve's orientation. The total flow through the artery was highest when the valve was oriented with its axis of symmetry intersecting the artery's opening. The findings of this research may assist surgeons in choosing the best orientation for BMHV implantation. The bileaflet valve was donated by St. Jude Medical. Financial support was provided by the Natural Sciences and Engineering Research Council of Canada.

    Aims: The aim was to review epidemiologic studies to reassess whether serum levels of triglycerides should be considered independently of high-density lipoprotein-cholesterol (HDL-C) as a predictor of coronary heart disease (CHD). Methods and results: We systematically reviewed population-based cohort studies in which baseline serum levels of triglycerides and HDL-C were included as explanatory variables in multivariate analyses with the development of CHD (coronary events or coronary death) as dependent variable. A total of 32 unique reports describing 38 cohorts were included. The independent association between elevated triglycerides and risk of CHD was statistically significant in 16 of 30 populations without pre-existing CHD. Among populations with diabetes mellitus or pre-existing CHD, or the elderly, triglycerides were not significantly independently associated with CHD in any of 8 cohorts. Triglycerides and HDL-C were mutually exclusive predictors of coronary events in 12 of 20 analyses of patients without pre-existing CHD. Conclusions: Epidemiologic studies provide evidence of an association between triglycerides and the development of primary CHD independently of HDL-C. Evidence of an inverse relationship between triglycerides and HDL-C suggests that both should be considered in CHD risk estimation and as targets for intervention. PMID:19436658

It can induce and promote the atherosclerotic process by means of several mechanisms involving endothelial shear stress and biochemical activities. Furthermore, elevated heart rate can directly increase heart ischemic conditions because of its skill in unbalancing demand/supply of oxygen and decreasing the diastolic period. Thus, many pharmacological treatments have been proposed in order to reduce heart rate and ameliorate the cardiovascular risk profile of individuals, especially those suffering from coronary artery diseases (CAD and chronic heart failure (CHF. Ivabradine is the first pure heart rate reductive drug approved and currently used in humans, created in order to selectively reduce sinus node function and to overcome the many side effects of similar pharmacological tools (ie, β-blockers or calcium channel antagonists. The aim of our review is to evaluate the role and the safety of this molecule on CAD and CHF therapeutic strategies.

    The aim was to investigate the effects of dietary intakes of different types of sugars (extrinsic, intrinsic, and lactose) and the dietary fat to sugar ratio on prevalent coronary heart disease (CHD). This was a baseline cross sectional survey of CHD risk factors. Twenty two Scottish health districts were surveyed between 1984 and 1986. A total of 10,359 men and women aged 40-59 years were screened as part of the Scottish Heart Health Study, and a further 1267 men and women aged 25-39 and 60-64 years were screened as part of the Scottish MONICA (monitoring trends and determinants in cardiovascular disease) Study. The response rates were 74% and 64% respectively. Subjects completed a questionnaire which included sociodemographic, health, and food frequency information. Medical history, response to the Rose chest pain questionnaire, and results of a 12 lead ECG recording were used to categorize subjects into CHD diagnosed, previously CHD undiagnosed, or no CHD groups. The chi 2 statistic was used to determine whether the CHD groups differed in their sugar consumption, and multiple logistic regression analysis, with adjustment for other potential coronary risk factors, was used to calculate odds ratios for prevalent CHD by intake fifths of dietary sugars. Men, but not women, differed in their sugar consumption by CHD group. The odds ratios showed a tendency for a U shaped relationship for extrinsic sugar intake with CHD prevalence, but no significant effect of the fat to sugar ratio (possible marker of obesity) on CHD was seen. The results suggest that neither extrinsic sugar, intrinsic sugar, nor the fat to sugar ratio are significant independent predictors of prevalent CHD in the Scottish population, when the other major risk factors such as cigarette smoking, blood cholesterol concentration, and antioxidant vitamins intake are accounted for. These new data for different sugar types agree with the consensus view that total sugar intake is not a major marker of

    Exercise stress electrocardiography (ExECG) is underutilized as the initial test modality in patients with interpretable electrocardiograms able to exercise. Although, stress myocardial imaging techniques provide valuable diagnostic and prognostic information, variables derived from ExECG can yield substantial data for risk stratification, either supplementary to imaging variables, or without concurrent imaging. In addition to exercise-induced ischemic ST depression, such markers as ST segment elevation in lead AVR, abnormal heart rate recovery post-exercise, failure to achieve target heart rate, and poor exercise capacity improve risk stratification of ExECG. For example, patients achieving ≥10 METS on ExECG have a very low prevalence of inducible ischemia and an excellent prognosis. In contrast, cardiac imaging techniques add diagnostic and prognostic value in higher risk populations (e.g. poor functional capacity, diabetes, chronic kidney disease). Optimal test selection for symptomatic patients with suspected coronary artery disease requires a patient-centered approach factoring in the risk/benefit ratio and cost-effectiveness. PMID:26563861

    Full Text Available Cardiovascular disease is the leading cause of global mortality, with coronary heart disease (CHD its major manifestation. Although inflammation, the body’s response to noxious stimuli, is implicated in several stages of CHD development, the relevance of circulating levels of markers of inflammation to CHD risk remains uncertain. This review summarizes available epidemiological evidence for four emerging inflammatory markers implicated in CHD (fibrinogen, C-reactive protein, lipoprotein-associated phospholipase A2 and interleukin-6; considers their likely utility in cardiovascular risk prediction; and outlines areas of outstanding uncertainty.

    Objective To determine whether educational attainment is a causal risk factor in the development of coronary heart disease.Design Mendelian randomisation study, using genetic data as proxies for education to minimise confounding.Setting The main analysis used genetic data from two large consortia (CARDIoGRAMplusC4D and SSGAC), comprising 112 studies from predominantly high income countries. Findings from mendelian randomisation analyses were then compared against results from traditional observational studies (164 170 participants). Finally, genetic data from six additional consortia were analysed to investigate whether longer education can causally alter the common cardiovascular risk factors.Participants The main analysis was of 543 733 men and women (from CARDIoGRAMplusC4D and SSGAC), predominantly of European origin.Exposure A one standard deviation increase in the genetic predisposition towards higher education (3.6 years of additional schooling), measured by 162 genetic variants that have been previously associated with education.Main outcome measure Combined fatal and non-fatal coronary heart disease (63 746 events in CARDIoGRAMplusC4D).Results Genetic predisposition towards 3.6 years of additional education was associated with a one third lower risk of coronary heart disease (odds ratio 0.67, 95% confidence interval 0.59 to 0.77; P=3×10-8). This was comparable to findings from traditional observational studies (prevalence odds ratio 0.73, 0.68 to 0.78; incidence odds ratio 0.80, 0.76 to 0.83). Sensitivity analyses were consistent with a causal interpretation in which major bias from genetic pleiotropy was unlikely, although this remains an untestable possibility. Genetic predisposition towards longer education was additionally associated with less smoking, lower body mass index, and a favourable blood lipid profile.Conclusions This mendelian randomisation study found support for the hypothesis that low education is a causal risk factor in the

    Atherosclerosis is an important component of coronary heart disease (CHD), which is the leading cause of death worldwide, including in Japan. Because atherosclerotic processes are typified by chronic inflammatory responses, which are similar to those elicited by chronic infection, the role of infection in promoting or accelerating atherosclerosis has received considerable focus. Increasing evidence supports the notion that periodontitis is associated with increased risk of atherosclerosis through dysfunction of endothelial cells induced by either periodontopathic bacteria or their products, or inflammatory mediators derived from infected periodontal tissue. Here we review whether periodontitis represents a risk factor for CHD or atherosclerosis, particularly in a Japanese population.

    Currently, there are many types of classification of coronary circulation. The first type was introduced in 1904 by Banchi. Hettler provides very detailed criteria for the type classification based on the course of the anterior and posterior interventricular branches. Hettler defined the following types: left coronary artery dominance, right coronary artery dominance, and co-dominant. The objective of this study was to analyse coronary circulation types in the studied material and their correlation with heart size and gender. The study was carried out on 102 human hearts (59 male and 43 female). True casts of coronary vessels were obtained using epoxide resins. The prepared specimens were measured for heart dimensions and evaluated for coronary circulation type. The majority of the specimens were classified as the co-dominant type, followed by the right coronary artery dominant type. The left-dominant coronary artery type represented the lowest number of heart specimens. No statistically significant correlation between the type of coronary circulation and heart size or gender was found. The coronary circulation type is not correlated with heart size or with gender. This confirms that it is a hereditary trait.

    Full Text Available OBJECTIVE: To access the incidence of diagnostic errors in the initial evaluation of children with cardiac murmurs. METHODS: We evaluated our 7-years of experience in a public pediatric cardiology outpatient clinic. Of 3692 patients who were sent to the hospital, 2603 presented with a heart murmur and were investigated. Patients for whom a disagreement existed between the initial and final diagnoses were divided into the following 2 groups: G1 (n=17 with an initial diagnosis of an innocent murmur and a final diagnosis of cardiopathy, and G2 (n=161 with an initial diagnosis of cardiopathy and a final diagnosis of a normal heart. RESULTS: In G1, the great majority of patients had cardiac defects with mild hemodynamic repercussions, such as small ventricular septal defect and mild pulmonary stenosis. In G2, the great majority of structural defects were interventricular communication, atrial septal defect and pulmonary valve stenosis. CONCLUSION: A global analysis demonstrated that diagnostic error in the initial evaluation of children with cardiac murmurs is real, reaching approximately 6% of cases. The majority of these misdiagnoses were in patients with an initial diagnosis of cardiopathy, which was not confirmed through later complementary examinations. Clinical cardiovascular examination is an excellent resource in the evaluation of children suspected of having cardiopathy. Immediate outpatient discharge of children with an initial diagnosis of an innocent heart murmur seems to be a suitable approach.

    Serbia's interventional community has been facing the multifaceted challenge of an ageing population with cardiovascular diseases as the primary cause of death nationwide, coronary artery disease (CAD) being the most prevalent subset. The following two fields of activity have marked the trajectory of progress in the field of interventional cardiology in Serbia: first, the expansion of the infrastructure, mainly through the opening of new catheterisation laboratories across all of the country's administrative regions, which has resulted in better accessibility to coronary interventions for the general population; second, the creation of national platforms for continuous education, training and the promotion of clinical research in interventional cardiology, with close programmatic links to European Association of Percutaneous Cardiovascular Interventions (EAPCI)-based educational initiatives, including the curriculum for interventional cardiology. As growth seems to be inherent to the concept of progress, we report here on the expanding numbers of coronary interventions in the period between January 2010 and December 2015, and the early experiences with structural heart interventions in Serbia.

    Full Text Available The ear has a reflexive property; therefore, various physical attributes may appear on the auricle when disorders of the internal organs or other parts of the body exist. Auricular diagnostics is an objective, painless, and noninvasive method that provides rapid access to information. Thus, the association between auricular signals and coronary heart disease (CHD should be further investigated. A case control study was conducted to determine the predictive value of auricular signals on 100 cases of CHD (CHD+ve = 50; CHD−ve = 50 via visual inspection, electrical skin resistance measurement, and tenderness testing. The results showed that the presence of an ear lobe crease (ELC was significantly associated with coronary heart disease. The “heart” zone of the CHD+ve group significantly exhibited higher conductivity on both ears than that of the controls. The CHD+ve group experienced significant tenderness in the “heart” region compared with those in the CHD−ve group in both acute and chronic conditions. Further studies that take into consideration the impact of age, race, and earlobe shape on ELC prevalence in a larger sample should be done.

    2012-02-01

    Patients with obesity and diabetes mellitus are at increased risk for cardiovascular events and have a higher cardiovascular morbidity and mortality. This worse prognosis is partly explained by the late recognition of coronary heart disease in these patients, due to the absence of symptoms. Early identification of coronary heart disease is vital, to initiate preventive medical therapy and improve prognosis. At present, with the use of cardiovascular risk models, the identification of coronary heart disease in these patients remains inadequate. To this end, biomarkers should improve the early identification of patients at increased cardiovascular risk. The first part of this review describes the pathophysiologic pathway from obesity to coronary heart disease. The second part evaluates several mediators from this pathophysiologic pathway for their applicability as biomarkers for the identification of coronary heart disease.

    The Israel Heart Society is a member of the European Society of Cardiology, and the Israeli Working Group of Interventional Cardiology is an active participant in EAPCI. The aim of this manuscript is to provide a snapshot of cardiac interventions performed in the State of Israel during the period 2010-2015. Data for this manuscript were collected via collaboration with the National Diseases Registries Unit of the Israel Center for Disease Control. During the survey period, the Israeli population increased by 7% but only one additional hospital with an active cardiac catheterisation laboratory was opened. The vast majority of the percutaneous procedures are performed in public hospital settings. Total coronary angiography procedures remained stable throughout the survey period, and the percentage of PCI out of total coronary angiography procedures remained approximately 50% throughout the survey period. More than 90% of the PCI procedures were performed using stent deployment, and the use of drug-eluting stents increased significantly during the survey period from 46% in 2010 to 92% in 2015. The number of TAVI procedures increased dramatically, by more than sixfold, from 130 procedures in 2010 to 851 procedures in 2015 (with 130 implants/million population at Q4 of 2015). The vast majority of interventional cardiology procedures are funded by the governmental healthcare providers, and all the citizens of the country have access to the most advanced cardiac interventions. If corrected for the increase in the population, the volumes of coronary interventions are decreasing throughout the country. However, structural heart disease interventions, and specifically valvular interventions, are growing rapidly and this trend is expected to continue in the near future.

    Cold agglutination was suspected in 2 pediatric open heart surgery cases during mild hypothermic cardiopulmonary bypass. The first patient was a 2-year-old boy with secundum atrial septal defect. Fifteen minutes after the initiation of mild hypothermic cardiopulmonary bypass, the inlet pressure of oxygenator suddenly elevated from 250 to over 500 mmHg, whereas outlet pressure was maintained. The blood flow rate decreased from 140 to 85 ml/kg/min. At that time, the arterial blood temperature was less than 32°C. Cold agglutinin was highly suspected, so patient was immediately warmed, and the inlet pressure of oxygenator decreased to 250 mmHg when the arterial blood temperature reached to 36°C. Second patient was a 3-year-old boy with secondary developed subvalvular pulmonary stenosis after the repair of double chambered right ventricle at 10 months of his age. Eighteen minutes after the initiation of mild hypothermic cardiopulmonary bypass, the inflow pressure suddenly elevated to 500 mmHg and transmission flow decreased to 55 ml/kg/min. Twenty-three minutes after warming, the pressure fell to a normal level and transmission flow was recovered. The operation continued with normo-thermic cardiopulmonary bypass and crystalloid cardioplegia. Both cases had no postoperative complications related to cold agglutinin such as myocardial infarction, cerebral infarction, or renal insufficiency.

    The diagnosis of new onset congestive heart failure (CHF) is often difficult as symptoms and signs are non-specific. Proper diagnostic investigations and treatments are underused in primary care. To describe a management programme for patients with suspected CHF in primary care in cooperation with specialists in cardiology. Prospective study of 102 consecutive primary care patients with suspected new onset CHF referred to an easily accessible hospital-based cardiology outpatient clinic management programme. Following clinical examination, ECG, echocardiography, blood chemistry including NT-proBNP, and assessment of NYHA class and quality of life (EQ5D), patients with a confirmed diagnosis of CHF were prescribed medication with advice on titration and target doses. Trained CHF nurses gave Information on CHF and provided follow up. Half (47%) of the referred patients had the diagnosis of CHF confirmed. Low NT-proBNP values (CHF group was 86% ACE-inhibitors/angiotensin receptor blockers, 61% ß-blocking agents, and 81% diuretics (P CHF in primary care, with referral to a hospital-based specialist team, can be applied successfully.

    To describe perceived social support among patients with coronary heart disease following percutaneous coronary intervention. A low level of social support is considered a risk factor for coronary heart disease in healthy individuals and reduces the likelihood that people diagnosed with coronary heart disease will have a good prognosis. A descriptive cross-sectional study. A survey of 416 patients was conducted in 2013. A self-report instrument, Social Support of People with Coronary Heart Disease, was used. The instrument comprises three dimensions of social support: informational, emotional, functional supports and 16 background variables. Data were analysed using descriptive statistics, factor analysis, mean sum variables and multivariate logistic regression. Perceived informational support was primarily high, but respondents' risk factors were not at the target level. The weakest items of informational support were advice on physical activity, continuum of care and rehabilitation. Regarding the items of emotional support, support from other cardiac patients was the weakest. The weakest item of functional support was respondents' sense of the healthcare professionals' care of patients coping with their disease. Background variables associated with perceived social support were gender, marital status, level of formal education, profession, physical activity, duration of coronary heart disease and previous myocardial infarction. Healthcare professionals should pay extra attention to women, single patients, physically inactive patients, those demonstrating a lower level of education, those with a longer duration of CHD, and respondents without previous acute myocardial infarction. Continuum of care and counselling are important to ensure especially among them. This study provides evidence that healthcare professionals should be more aware of the individual needs for social support among patients with coronary heart disease after percutaneous coronary intervention

    A variety of rist factors have been suspected for causing the coronary heart disease. 406 cases of both sex groups with age range of 35 to 55 years were selected from three distinct localities of varanasi city. Individuals who reported single or more risk factors of CHD were isolated from the population of the particular areas. After a detailed preliminary screening of the subjects various physical, physiological, psychological and biochemical measurements were carried out. Other basis of initial findings, the cases who sowed abnormal lipid profile with dominant psychological involvement were given the organic extract of Inula racemosa (Pushkarmool), commiphora mukul (Guggulu), centella asiatica (Mandukaparni) and Hypericum perforatum (Basant in prescribed doses continuously for 6 moths. Correction in the lipid profile including triglycerides, blood pressure and the psychological factors like anxiety and depression to a significant level following least drugs treatment indicated the cardioprotective and therapeutic effects of the present formulation. Hence, by modifying the coronary risk factors, the incidence of CD can be minimized to a great extent as well as the test formulation may also be advocated in the prevention and management of CHD.

    The article assesses the influence of mono- and multivascular lesions of coronary arteries on the course of coronary heart disease at patients with diabetes mellitus type 2. For this purpose, a comprehensive survey of 75 patients with coronary heart disease and diabetes mellitus type 2 was arranged. Depending on the number of vascular lesions of the coronary arteries, according to the data of coronary arteries computer tomography, all patients were divided into two subgroups. The first subgroup included 27 patients with coronary heart disease and diabetes mellitus type 2 with monovascular lesions of coronary arteries. To the second subgroup were included 48 patients with coronary heart disease and diabetes mellitus type 2 with multivascular lesions of coronary arteries. During the analysis of carbohydrate metabolism in cases of coronary heart disease and diabetes mellitus type 2 the HOMA index increase by 25.40% and insulin level increase by 17.05% were revealed at patients with multivascular lesions of coronary arteries in comparison with patients with monovascular lesions of coronary arteries, respectively. The combination of coronary heart disease and diabetes mellitus type 2 with multivascular lesions of coronary arteries was associated with an increase of sortilin level (233,47±47,85 ng/l). A significant increase in triglycerides, lipoprotein cholesterol of very low density influences greatly on the progression of coronary atherosclerosis with lesions of greater number of coronary arteries at patients surveyed. At patients with coronary heart disease and diabetes mellitus type 2 with multivascular lesions of coronary arteries the left ventricle myocardial re-modeling occurred through the increase of left ventricle's size and cavity.

    Exercise testing, a major diagnostic modality in individuals with suspected coronary artery disease (CAD), has in general demonstrated less overall diagnostic accuracy in women compared to men. As part of the WISE, a modified protocol was examined with the intention of improving reliability of exercise testing. Criteria for entry in the WISE study include clinically indicated coronary angiography. Exercise testing was performed using a protocol modified to be more appropriate for women. The study population consisted of 96 women, mean age of 55.8 y (range 34-77), who completed exercise treadmill test (ETT). Most (78%) were postmenopausal; 96% had >or =2 risk factors for CAD. By core laboratory angiography, 29/96 women had stenosis > or =50% in at least one coronary artery. Of these 29 women, 9 had abnormal ETT, yielding overall sensitivity of 31%. The remaining 20 women had normal (12/29, 41%) or nondiagnostic (8/29, 28%) studies. Among the 67 women with minimal or no coronary stenosis, 35 had no ischemic ST-segment changes during ETT, yielding overall specificity of 52%. Analysis with exclusion of women with nondiagnostic studies yielded sensitivity and specificity of 43% and 66%, respectively. The presence of coronary artery stenosis and inability to perform ETT, but not results of testing, predicted the outcomes of myocardial infarction, heart failure, and death. Exercise treadmill test appears to be of limited diagnostic value in women with suspected myocardial ischemia referred for coronary angiography. Sensitivity and specificity remain poor even with modified exercise protocol and core laboratory angiographic analysis. These findings merit consideration in view of current guidelines that recommend exercise testing in women with suspected CAD.

    Many patients with angina and signs of myocardial ischemia on stress testing have no significant obstructive epicardial coronary disease. There are many potential coronary and non-coronary mechanisms for ischemia without obstructive epicardial coronary disease, and prominent among these is coronary microvascular and/or endothelial dysfunction. Patients with coronary microvascular and/or endothelial dysfunction are often at increased risk of adverse cardiovascular events, including ischemic events and heart failure despite preserved ventricular systolic function. In this article, we will review the diagnosis and treatment of coronary microvascular and endothelial dysfunction, discuss their potential contribution to heart failure with preserved ejection fraction, and highlight recent advances in the evaluation of atherosclerotic morphology in these patients, many of whom have non-obstructive epicardial disease.

    2016-06-01

    To evaluate the correlation between the coronary sinus flow and the infusion volume in the coronaries and assess the performance of coronary sinus flow in predicting coronary artery occlusion in an isolated pig heart. The coronary sinus flow was measured in 16 isolated pig hearts by pulsed Doppler ultrasound. The correlation between the coronary sinus flow and the infusion volume in different coronary artery was analyzed, and the performance of coronary sinus flow in predicting different coronary artery occlusion was deducted. There were no statistically significant differences between the coronary sinus flow and the infusion volume in different coronary artery (p>0.05). The correlations between the coronary sinus flow and the infusion volume in left anterior descending coronary artery (LAD), left circumflex coronary artery (LCX), LAD and LCX, and LAD, LCX and right coronary artery (RCA) were all higher than 0.85 (p85% sensitivity and specificity. Excepting RCA mild occlusion (80% sensitivity and specificity. Conclusions The coronary sinus flow measured by pulsed Doppler ultrasound can effectively and exactly reflect the infusion volume in coronaries, which is a powerful indicator of coronary blood supply.

    Our aim is to assess perception of risk of developing coronary heart disease and to examine its associations with individuals' characteristics and health behaviours among Omani people with type 2 diabetes mellitus (T2DM). Evaluating perceptions of being at risk of developing a disease may give insight into health promotion behaviours. People with diabetes are at high risk of coronary heart disease. The management of diabetes mellitus should include prevention and control of coronary heart disease. A cross-sectional correlational study was conducted. A convenience sample of 160 adults with T2DM was invited to participate in this study between November 2014 and March 2015. Descriptive and regression analyses were performed to examine associations between study variables. Perception of risk of developing coronary heart disease was significantly associated with low educational level (β = 0.191, P level of knowledge about diabetes mellitus (β = 0.200, P < .05). People with T2DM who perceived coronary heart disease as having few moderate known outcomes and consequences reported consuming healthy diet more frequently. Teaching people with T2DM about the risk of developing coronary heart disease is essential as it could motivate them to perform health promotion behaviours, which may assist in controlling and reducing coronary heart disease. © 2017 John Wiley & Sons Australia, Ltd.

    2002-05-01

    To study the relativity between Streptococcus sanguis group (SSG) and coronary heart disease (CHD). 41 individuals were diagnosed with CHD and 18 normals served as controls. All of them had undergone coronary angiography. Their social class (including education and wages), smoking, drinking, blood lipids and oral health were also recorded. SSG in saliva and subgingival plaque were cultivated in NAYS-B agar plates and counted. SSG were identified into species with routine biochemical reaction and AP-PCR. In the multiple step regression analysis, the amount of SSG in saliva and subgingival plaque were positively associated with severe coronary atheromatosis after adjusting the classical risk factors of CHD. The average amount of SSG in saliva was (435 +/- 422) x 10(8) CFU/L in CHD group and (358 +/- 540) x 10(8) CFU/L in control group, F = 2.72, P = 0.08; the average amount of SSG in incisor was (331 +/- 484) x 10(7) CFU/L in CHD group and (98 +/- 164) x 10(7) CFU/L in control group, F = 5.54, P = 0.02; the average amount of SSG in molar was (352 +/- 381) x 10(7) CFU/L in CHD group and (185 +/- 232) x 10(7) CFU/L in control group, F = 2.86, P = 0.10. S. sanguis and S. gordonii were more in CHD group than in control group (P 0.05). The increase of SSG in oral floras may play an important role in the occurrence of CHD.

    Despite the availability of high-sensitive troponin (hs-cTnT), there is still room for improvement in the diagnostic assessment of patients suspected of acute coronary syndrome (ACS). Apart from serial biomarker testing, which is time-consuming, novel biomarkers like copeptin have been proposed to expedite the early diagnosis of suspected ACS in addition to hs-cTnT. We determined whether placenta derived growth factor (PlGF), soluble Fms-like tyrosine kinase 1 (sFlt-1), myoglobin, N-terminal prohormone B-type Natriuretic Peptide (NT-proBNP), growth-differentiation factor 15 (GDF-15) and copeptin improved early assessment of chest pain patients. This prospective, single centre diagnostic FAME-ER study included patients presenting to the ED with symptoms suggestive of ACS. Blood was collected to measure biomarkers, notably, hs-cTnT was retrospectively assessed. Added value of markers was judged by increase in AUC using multivariable logistic regression. Of 453 patients enrolled, 149 (33%) received a final diagnosis of ACS. Hs-cTnT had the highest diagnostic value in both univariable and multivariable analysis. PPVs of the biomarkers ranged from 23.5% (PlGF) to 77.9% (hs-cTnT), NPVs from 67.0% (PlGF) to 86.4% (hs-cTnT). Only myoglobin yielded diagnostic value in addition to clinical symptoms and electrocardiography (ECG) (AUC of clinical model 0.80) with AUC of 0.84 (pimproved diagnostic performance. When assessing patients suspected of ACS, only myoglobin had added diagnostic value beyond clinical symptoms and ECG. However, when combined with hs-cTnT, it yields no additional diagnostic value. PlGF, sFlt-1, NT-proBNP, GDF-15 and copeptin had no added value to the clinical model or hs-cTnT.

    Objectives: (1) To establish the prevalence of incidental extra-cardiac findings (ECFs) in coronary multi detector computed tomography (CCT) performed in a large, homogeneous cohort of patients suspected of coronary artery disease (CAD). (2) To examine whether any association can be established between ECFs and pretest risk as determined by conventional risk factors for CAD, the Diamond-Forrester risk model or coronary artery calcium scores. (3) To assess cost related to extra-cardiac examinations. Design: Retrospective study of consecutive patients who had CCT performed. A large field of view was recreated from the non-enhanced CT scan and evaluated by a radiologist for incidental ECFs. Subjects: Patients with chest pain referred to CTA by a cardiologist. Results: In 1383 patients a total of 481 ECFs were indentified, 378 minor (meaning no follow-up was needed) and 103 major ECFs (ECF followed up clinically and/or with additional imaging), in a total of 393 (28%) patients. 85 (6%) patients had one major ECF and 9 (0.7%) patients had two major ECFs. In 19 (4 cases of malignancy) patients the major ECF had therapeutic consequences. Significant positive associations were found between age and smoking, respectively and the presence of ECFs. The cost estimate of saving one life from malignant disease based on ECF examinations is 40,190 Euro . Conclusion: Incidental extra-cardiac findings are common, sometimes revealing serious, even malignant disease. Diagnostic follow-up of major ECFs seems to be cost-effective in a Danish clinical setting. We recommend investigating a large field of view for incidental ECFs following CCT.

    A coronary heart disease index was developed from longitudinal ECG (LCG) tracings to serve as a cardiac health measure in studies of working and, essentially, asymptomatic populations, such as pilots and executives. For a given subject, the index consisted of a composite score based on the presence of LCG aberrations and weighted values previously assigned to them. The index was validated by correlating it with the known presence or absence of CHD as determined by a complete physical examination, including treadmill, resting ECG, and risk factor information. The validating sample consisted of 111 subjects drawn by a stratified-random procedure from 5000 available case histories. The CHD index was found to be significantly more valid as a sole indicator of CHD than the LCG without the use of the index. The index consistently produced higher validity coefficients in identifying CHD than did treadmill testing, resting ECG, or risk factor analysis.

    Full Text Available Introduction & Objective: In modern medicine, researches in behavioural sciences have described link between psychosocial characteristic, specific personality traits, and development of coronary artery disease. The aim of present study was to investigate the relationship between " hostility" and "type A" personality with acute myocardial infarction. Materials & Methods: In this case-control study 102 patients suffering from acute myocardial infarction and 162 no patents individuals after matching by age, gender, education level, marital status and occupation were studied and compared with regard psychological conditions by type A Najarian questionnaire and SCL – 90 – R. Results: Our study found evidence in support of the hypothesis that hostility may predict heart disease more than type A personality.Conclusion: Our study has some practical meaning for prediction and prevention of CHD. This finding suggests that mental health providers should continue to look at the effectiveness of providing psychological intervention for those individuals with high hostility levels.

    As a result of the Seven Countries Study, the Mediterranean diet has been popularized as a healthy diet. Nevertheless, it has not replaced the prudent diet commonly prescribed to coronary patients. Recently, we completed a secondary, randomized, prospective prevention trial in 605 patients recovering from myocardial infarction in which we compared an adaptation of the Cretan Mediterranean diet with the usual prescribed diet. After a mean follow-up period of 27 mo, recurrent myocardial infarction, all cardiovascular events, and cardiac and total death were significantly decreased by > 70% in the group consuming the Mediterranean diet. These protective effects were not related to serum concentrations of total, low-density-lipoprotein (LDL), or high-density-lipoprotein (HDL) cholesterol. In contrast, protective effects were related to changes observed in plasma fatty acids: an increase in n-3 fatty acids and oleic acid and a decrease in linoleic acid that resulted from higher intakes of linolenic and oleic acids, but lower intakes of saturated fatty acids and linoleic acid. In addition, higher plasma concentrations of antioxidant vitamins C and E were observed. We conclude that a Cretan Mediterranean diet adapted to a Western population protected against coronary heart disease much more efficiently than did the prudent diet. Thus, it appears that the favorable life expectancy of the Cretans could be largely due to their diet.

    In the last decades, the role of inflammation in the pathogenesis of atherosclerosis has been the topic of intense research. Several markers of inflammation have shown predictive value for first and recurrent coronary events in patients without and with established coronary heart disease (CHD). Among these markers, lipoprotein-associated phospholipase A2 (Lp-PLA2) has recently received considerable attention. In the present review, the potential role of Lp-PLA2 as a marker of CHD risk and as a therapeutic target is discussed. Elevated Lp-PLA2 mass and activity appears to be associated with increased risk for CHD, both in the general population and in patients with established CHD. However, it is unclear whether the measurement of Lp-PLA2 improves risk discrimination when incorporated in models that include traditional cardiovascular risk factors. Moreover, the lack of effect on CHD events of darapladib, a potent, selective Lp-PLA2 inhibitor, in two large, randomized, placebo-controlled trials and the mostly negative findings of genetic association studies suggest that Lp-PLA2 is unlikely to represent a causal factor in atherogenesis. Therefore, it is doubtful whether Lp-PLA2 will constitute a therapeutic target for the prevention of CHD.

    Full Text Available Abstract Background Few studies have focused on the association between the sociodemographic characteristics of a patient with the change in health-related quality of life (HRQOL following invasive coronary procedures, and the results remain inconclusive. The objective of the present study was to measure the temporal changes in HRQOL of patients with coronary heart disease, and assess how these changes are associated with invasive coronary procedures and sociodemographic characteristics. Methods This was a prospective study of 254 patients with angina pectoris and 90 patients with acute coronary syndrome. HRQOL was assessed with the multi-item scales and summary components of the SF-36, both 6 weeks and 2 years after baseline hospitalization in 1998. Paired t-tests and multiple regression analyses were used to assess temporal changes in HRQOL and to identify the associated factors. Results Physical components of HRQOL had improved most during the 2 years following invasive coronary procedures. Our findings indicated that patients with angina pectoris who were younger, male, and more educated were most likely to increase their HRQOL following invasive coronary procedures. When adjusting for baseline HRQOL scores, invasive coronary procedures and sociodemographic characteristics did not explain temporal changes in patients with acute coronary syndrome, possibly due to higher comorbidity. Conclusion Sociodemographic characteristics should be taken into account when comparing and interpreting changes in HRQOL scores in patients with and without invasive coronary procedures.

    Aims To develop a clinical cardiac risk algorithm for stable patients with suspected CAD based upon angina typicality and CAD risk factors. Methods and Results Between 2004 and 2011, 14,004 adults with suspected CAD referred for cardiac imaging were followed: 1) 9,093 patients for CCTA (CCTA-1) followed for 2.0 years; 2) 2,132 patients for CCTA (CCTA-2) followed for 1·6 years, and 3) 2,779 patients for exercise myocardial perfusion scintigraphy followed for 5.0 years. A best-fit model from CCTA-1 for prediction of death or myocardial infarction (MI) was developed, with integer values proportional to regression coefficients. Discrimination was assessed using C-statistic. The validated model was also tested for estimation of the likelihood of obstructive CAD, defined as ≥50% stenosis, as compared to method of Diamond and Forrester (D-F). Primary outcomes included all-cause mortality and non-fatal MI. Secondary outcomes included prevalence of angiographically obstructive CAD. In CCTA-1, best-fit model discriminated individuals at risk of death or MI (C-statistic 0·76). The integer model ranged from 3-13, and corresponded to 3-year death risk or MI of 0·25% to 53·8%. When applied to the CCTA-2 and MPS, the model demonstrated C-statistics of 0·71 and 0·77. Both best-fit (C=0·76, 95% CI 0·746-0·771) and integer model (C=0·71, 95% CI 0·693-0·719) performed better than D-F (C=0·64; 95% CI, 0·628-0·659) for estimating obstructive CAD. Conclusions For stable symptomatic patients with suspected CAD, we developed a history-based method for prediction of death and obstructive CAD. PMID:25865923

    The major factors determining myocardial perfusion and oxygen delivery have been elucidated over the past several decades, and this knowledge has been incorporated into the management of patients with ischemic heart disease (IHD). The basic understanding of the fluid mechanical behavior of coronary stenoses has also been translated to the cardiac catheterization laboratory where measurements of coronary pressure distal to a stenosis and coronary flow are routinely obtained. However, the role of perturbations in coronary microvascular structure and function, due to myocardial hypertrophy or coronary microvascular dysfunction, in IHD is becoming increasingly recognized. Future studies should therefore be aimed at further improving our understanding of the integrated coronary microvascular mechanisms that control coronary blood flow, and of the underlying causes and mechanisms of coronary microvascular dysfunction. This knowledge will be essential to further improve the treatment of patients with IHD. Copyright © 2014 Elsevier Inc. All rights reserved.

    To estimate parameters of the function relating alcohol consumption with the risk of coronary heart disease and to identify the sources of heterogeneity in the parameter estimates. A search of the epidemiological literature from 1966 to 1998 was performed using several bibliographic databases. Meta-regression models were fitted to evaluate non-linear effects of alcohol intake on the relative risk. The effects of some characteristics of the studies, including an index of their quality, were considered as putative sources of heterogeneity of the estimates. Publication bias was also investigated. Among the 196 initially reviewed articles, 51 were selected. Since qualitative characteristics of the studies were significant sources of heterogeneity, the pooled dose-response functions were based on the 28 cohort studies with higher quality. Risk decreased from 0 to 20 g/day (RR = 0.80; 95% CI: 0.78, 0.83); there was evidence of a protective effect up to 72 g/day (RR = 0.96; 95% CI: 0.92, 1.00) and increased risk above > or = 89 g/day (RR = 1.05; 95% CI: 1.00, 1.11). Lower protective effects and harmful effects were found in women, in men living in countries outside the Mediterranean area and in studies where fatal events were used as the outcome. Evidence of publication bias for moderate intakes and of heterogeneity of the estimates across studies for higher intakes were found. The degree of protection from moderate doses of alcohol should be reconsidered. Further research investigating the effect of drinking patterns on the risk of coronary heart disease should be performed. Caution in making general recommendations is needed.

    The presence and extent of coronary artery calcium (CAC) are associated with increased risk for cardiovascular events. We determined whether information on the distribution of CAC and coronary dominance as detected by cardiac computed tomography were incremental to traditional Agatston score (AS) in predicting incident major coronary heart disease (CHD). We assessed total AS and the presence of CAC per coronary artery, per segment, and coronary dominance by computed tomography in participants from the offspring and third-generation cohorts of the Framingham Heart Study. The primary outcome was major CHD (myocardial infarction or CHD death). We performed multivariable Cox proportional hazards analysis and calculated relative integrated discrimination improvement. In 1268 subjects (mean age, 56.2±10.3 years, 63.2% men) with AS >0 and no history of major CHD, a total of 42 major CHD events occurred during median follow-up of 7.4 years. The number of coronary arteries with CAC (hazard ratio, 1.68 per artery; 95% confidence interval, 1.10-2.57; P =0.02) and the presence of CAC in the proximal dominant coronary artery (hazard ratio, 2.59; 95% confidence interval, 1.15-5.83; P =0.02) were associated with major CHD events after multivariable adjustment for Framingham risk score and categories of AS. In addition, measures of CAC distribution improved discriminatory capacity for major CHD events (relative integrated discrimination improvement, 0.14). Distribution of coronary atherosclerosis, especially CAC in the proximal dominant coronary artery and an increased number of coronary arteries with CAC, predict major CHD events independently of the traditional AS in community-dwelling men and women. © 2017 American Heart Association, Inc.

    Survival of patients with congenital heart defects has improved dramatically. Many will undergo interventional catheter or surgical procedures later in life. Others will develop atherosclerotic or post-surgical coronary heart disease. The coronary artery anatomy in patients with congenital heart disease differs substantially from that seen in the structurally normal heart. This has implications for diagnostic procedures as well as interventions. The unique epicardial course seen in some defects could impair interpretation of coronary angiograms. Interventional procedures, especially at the base of the heart, risk injuring unusually placed coronary arteries so that coronary artery anatomy must be delineated thoroughly prior to the procedure. In this review, we will describe the variants of coronary artery anatomy and their implications for interventional and surgical treatment and for sudden death during late follow-up in several types of congenital heart defects including: tetralogy of Fallot, truncus arteriosus, transposition of the great arteries, double outlet right ventricle, congenitally corrected transposition of the great arteries and defects with functionally one ventricle. We will also discuss the coronary abnormalities seen in Kawasaki disease.

    To determine the cost-effectiveness of natriuretic peptide (NP) testing and specialist outreach in patients with acute heart failure (AHF) residing off the cardiology ward. We used a Markov model to estimate costs and quality-adjusted life-years (QALYs) for patients presenting to hospital with suspected AHF. We examined diagnostic workup with and without the NP test in suspected new cases, and we examined the impact of specialist heart failure outreach in all suspected cases. Inputs for the model were derived from systematic reviews, the UK national heart failure audit, randomized controlled trials, expert consensus from a National Institute for Health and Care Excellence guideline development group, and a national online survey. The main benefit from specialist care (cardiology ward and specialist outreach) was the increased likelihood of discharge on disease-modifying drugs for people with left ventricular systolic dysfunction, which improve mortality and reduce re-admissions due to worsened heart failure (associated with lower utility). Costs included diagnostic investigations, admissions, pharmacological therapy, and follow-up heart failure care. NP testing and specialist outreach are both higher cost, higher QALY, cost-effective strategies (incremental cost-effectiveness ratios of £11,656 and £2,883 per QALY gained, respectively). Combining NP and specialist outreach is the most cost-effective strategy. This result was robust to both univariate deterministic and probabilistic sensitivity analyses. NP testing for the diagnostic workup of new suspected AHF is cost-effective. The use of specialist heart failure outreach for inpatients with AHF residing off the cardiology ward is cost-effective. Both interventions will help improve outcomes for this high-risk group. Copyright © 2017 International Society for Pharmacoeconomics and Outcomes Research (ISPOR). Published by Elsevier Inc.

    Full Text Available Cardiovascular diseases are caused because of abnormalities in the heart and blood vessels. Recent trends reveal that the incidence of coronary heart disease (CHD has gradually decreased in many developed countries, but the situation remains quite challenging in developing nations that account for more than 60% of the global burden. Multiple socio-demographic, personal, physician related and healthcare delivery system related factors have been identified which act in variable combinations to either influence the incidence of CHD or affect the short/long-term outcome of the disease. Of all CHD cases who succumb within 28 days of onset of symptoms, almost 67% fail to reach even a hospital. This clearly signifies the importance of primary prevention and early recognition of the warning signs in averting cause-specific mortality. The main priority is to develop cost-effective equitable health care innovations in CHD prevention and to monitor the trend of CHD so that evidence-based interventions can be formulated. To conclude, inculcating health-promoting behaviors in school children and the general population by means of community-based health screening and education interventions could avert many more deaths attributed to CHDs.

    Full Text Available Introduction: Coronary heart disease is known as the most common disease that causes mortality in the world, one of the examination to identify the risks of coronary heart disease is measuring waist circumference. The purpose of this study was to identify correlation between large waist circumferences and the incident of coroner heart disease. Method: Design used in this study was analytic observational (retrospective with cross sectional approach. There were 63 respondents which sampling by simple random sampling. The independent variable was waist circumferences and the dependent variable was coronary heart disease. Data were collected by direct observation then analyzed by spearman correlation statistic test with significance level α≤0.05. Result: The result showed that waist circumferences more than normal had significant correlation with the incident of coronary heart disease (p=0.02. Analysis: It can be concluded that there was correlation between waist circumferences more than normal and the incident of coronary heart disease to the clients with coroner cardiac disease. Discussion: Earlier screening and detection is needed to prevent coronary heart disease.

    Full Text Available Coronary heart disease (CHD patients who have undergone percutaneous coronary intervention (PCI have higher rates of depression than the general population. However, few researchers have assessed the impact of depression on the secondary prevention of CHD in China.The main purpose of this investigation was to explore the relationship between depression and secondary prevention of CHD in Chinese patients after PCI.This descriptive, cross-sectional one-site study recruited both elective and emergency PCI patients one year after discharge. Data from 1934 patients were collected in the clinic using questionnaires and medical history records between August 2013 and September 2015. Depression was evaluated by the 9-item Patient Health Questionnaire. Secondary prevention of CHD was compared between depression and non-depression groups.We found that depression affected secondary prevention of CHD in the following aspects: lipid levels, blood glucose levels, smoking status, physical activity, BMI, and rates of medication use.Depressive patients with CHD are at increased risk of not achieving the lifestyle and risk factor control goals recommended in the 2006 AHA guidelines. Screening should focus on patients after PCI because treating depression can improve outcomes by improving secondary prevention of CHD.

    The isolated beating pig heart model is an accessible platform to investigate the coronary circulation in its truly morphological and physiological state, whereas its use is beneficial from a time, cost, and ethical perspective. However, whether the coronary autoregulation is still intact is not known. Here, we study the autoregulation of coronary blood flow in the working isolated pig heart in response to brief occlusions of the coronary artery, to step-wise changes in left ventricular loading conditions and contractile states, and to pharmacologic vasodilating stimuli. Six slaughterhouse pig hearts (473 ± 40 g) were isolated, prepared, and connected to an external circulatory system. Through coronary reperfusion and controlled cardiac loading, physiological cardiac performance was achieved. After release of a coronary occlusion, coronary blood flow rose rapidly to an equal (maximum) level as the flow during control beats, independent of the duration of occlusion. Moreover, a linear relation was found between coronary blood flow and coronary driving pressure for a wide variation of preload, afterload, and contractility. In addition, intracoronary administration of papaverine did not yield a transient increase in blood flow indicating the presence of maximum coronary hyperemia. Together, this indicates that the coronary circulation in the isolated beating pig heart is in a permanent state of maximum hyperemia. This makes the model excellently suitable for testing and validating cardiovascular devices (i.e., heart valves, stent grafts, and ventricular assist devices) under well-controlled circumstances, whereas it decreases the necessity of sacrificing large mammalians for performing classical animal experiments. © 2013, Copyright the Authors.

    Perfusion-based whole organ decellularization has recently gained interest in the field of tissue engineering as a means to create site-specific extracellular matrix scaffolds, while largely preserving the native architecture of the scaffold. To date, this approach has been utilized in a variety of organ systems, including the heart, lung, and liver (1-5). Previous decellularization methods for tissues without an easily accessible vascular network have relied upon prolonged exposure of tissue to solutions of detergents, acids, or enzymatic treatments as a means to remove the cellular and nuclear components from the surrounding extracellular environment(6-8). However, the effectiveness of these methods hinged upon the ability of the solutions to permeate the tissue via diffusion. In contrast, perfusion of organs through the natural vascular system effectively reduced the diffusion distance and facilitated transport of decellularization agents into the tissue and cellular components out of the tissue. Herein, we describe a method to fully decellularize an intact porcine heart through coronary retrograde perfusion. The protocol yielded a fully decellularized cardiac extracellular matrix (c-ECM) scaffold with the three-dimensional structure of the heart intact. Our method used a series of enzymes, detergents, and acids coupled with hypertonic and hypotonic rinses to aid in the lysis and removal of cells. The protocol used a Trypsin solution to detach cells from the matrix followed by Triton X-100 and sodium deoxycholate solutions to aid in removal of cellular material. The described protocol also uses perfusion speeds of greater than 2 L/min for extended periods of time. The high flow rate, coupled with solution changes allowed transport of agents to the tissue without contamination of cellular debris and ensured effective rinsing of the tissue. The described method removed all nuclear material from native porcine cardiac tissue, creating a site-specific cardiac ECM

    Delta 9-tetrahydrocannabinol (THC) is the major active component of cannabis. Cardiovascular effects of THC have previously been reported: tachycardia after intake, but also bradycardia at higher doses. The purpose of this study was, firstly, to investigate the frequency and irregularity of heart rate in a group of cannabis users in their natural surroundings. We also compared THC-positive drivers with a regular pulse with THC-positive drivers with an irregular pulse. The division of Forensic Toxicology and Drug Abuse (DFTDA) at the Norwegian Institute of Public Heath analyzes blood samples from all drivers suspected of driving under the influence of drugs. We studied pulse rate and regularity in 502 THC-positive drivers who tested negative for other substances. As a control group, we randomly selected 125 drug-negative cases from the database of the DFTDA; no alcohol, narcotics, or medicinal drugs of abuse were detected. The Delta9-THC-positive drivers had a higher mean pulse rate than the control group [82.8 beats/min (SD 16.3) versus 75.6 beats/min (SD 9.2)] and more cases with tachycardia were detected in the Delta9-THC-positive group (19.4% versus 1.6%). There was only one driver with an irregular heart beat in the control group, while there were nine among the Delta9-THC-positive drivers. The drivers with an irregular pulse were over-represented amongst those with the lowest blood Delta9-THC concentrations. This report represents a large study of subjects in a real-life situation and includes observations on pulse frequency, regularity, and blood Delta9-THC concentration. A substantial fraction of Delta9-THC-positive drivers had tachycardia, but there was no correlation between blood Delta9-THC concentration and pulse rate in the present study. We had no further diagnostic information on the cause of the pulse irregularities, but our results indicate that occasional users of cannabis tend to have irregular heart rates at low THC concentrations and at low

    First to estimate the prevalence of significant coronary artery narrowings in patients suffering from valvular heart diseases requiring surgery and second to assess the parameters able to predict significant coronary stenoses in those patients. Retrospective study of a group consisting of 92 patients (29 female, 63 male, mean age 61 +/- 7.15 years) with coronary angiography carried out before surgical valve correction. Patients having ischemia-related mitral regurgitation were excluded from the study. Significant coronary artery stenosis was defined as a luminal narrowing of an epicardial artery of at least 50%. Anginal pain and cardiovascular risk factors were ascertained therewith. Significant coronary artery stenoses were found in 24% of all patient enrolled in the study, their prevalence in the subgroup with aortic valve disease (alone or associated with mitral valve disease) and in the subgroup with isolated mitral valve disease being similar (31.8% vs. 21.4%, p = 0.2). The anginal chest pain, increased waist circumference and a host of at least 3 conventional cardiovascular risk factors were the elements best correlated with the presence of significant coronary narrowings. Both Romanian patients and patients from industrialized countries afflicted with valvular heart diseases have similar prevalence of coronary heart disease. The prevalence tends to increase in patients with abdominal obesity and in those with many risk factors, diabetes mellitus being the most frequently encountered traditional risk factor. Renal function impairment might represent a predictive marker for coronary heart disease in valvular patients.

    Little is known about whether the childhood family psychosocial environment affects coronary heart disease (CHD). Study objectives were to evaluate associations of childhood family psychosocial environment (termed "risky families"; characterized by cold, unaffectionate interactions, conflict, aggression, neglect, and/or low nurturance) with calculated risk for CHD. Study participants included 3554 participants of the Coronary Artery Risk Development in Young Adults Study, aged 33 to 45 years. Childhood family psychosocial environment was measured using a risky family questionnaire via self-report. Ten-year CHD risk was calculated using the validated Framingham risk algorithm. In a multivariable-adjusted regression analysis adjusted for age, race/ethnicity, and childhood socioeconomic position, a 1-unit (range, 0-21) increase in risky family score was associated with 1.0% (95% confidence interval = 0.4%-1.7%) and 1.0% (95% confidence interval = 0.2%-1.8%) higher CHD risk in women and men, respectively. Multiple mediation analyses suggested significant indirect effects of education, income, depressive symptomatology, and anger-out expression in women and education in men, indicating that these may be mediating mechanisms between childhood psychosocial environment and CHD risk. Of the modifiable Framingham algorithm components, smoking (in women and men) and high-density lipoprotein (in women) were the factors most strongly associated with risky family score. Childhood family psychosocial environment was positively associated with the calculated 10-year CHD risk. Mechanisms may include the potential negative impact of childhood family psychosocial environment on later-life socioeconomic position (e.g., education in men and women) and/or psychosocial functioning (e.g., depression and anger-out expression in women), which may in turn lead to higher CHD risk, particularly through smoking (in men and women) and low level of high-density lipoprotein cholesterol (in women).

    Context Few studies have examined the association between the number of coronary heart disease risk factors and outcomes of acute myocardial infarction in community practice. Objective To determine the association between the number of coronary heart disease risk factors in patients with first myocardial infarction and hospital mortality. Design Observational study from the National Registry of Myocardial Infarction, 1994-2006. Patients We examined the presence and absence of 5 major traditional coronary heart disease risk factors (hypertension, smoking, dyslipidemia, diabetes, and family history of coronary heart disease) and hospital mortality among 542 008 patients with first myocardial infarction and without prior cardiovascular disease. Main Outcome Measure All-cause in-hospital mortality. Results A majority (85.6%) of patients who presented with initial myocardial infarction had at least 1 of the 5 coronary heart disease risk factors, and 14.4% had none of the 5 risk factors. Age varied inversely with the number of coronary heart disease risk factors, from a mean age of 71.5 years with 0 risk factors to 56.7 years with 5 risk factors (P for trend <.001). The total number of in-hospital deaths for all causes was 50 788. Unadjusted in-hospital mortality rates were 14.9%, 10.9%, 7.9%, 5.3%, 4.2%, and 3.6% for patients with 0, 1, 2, 3, 4, and 5 risk factors, respectively. After adjusting for age and other clinical factors, there was an inverse association between the number of coronary heart disease risk factors and hospital mortality adjusted odds ratio (1.54; 95% CI, 1.23-1.94) among individuals with 0 vs 5 risk factors. This association was consistent among several age strata and important patient subgroups. Conclusion Among patients with incident acute myocardial infarction without prior cardiovascular disease, in-hospital mortality was inversely related to the number of coronary heart disease risk factors.

    Increase in heart rate represents a significant contribution in the pathophysiology of coronary artery disease and heart failure, by promoting atherosclerotic process and endothelial dysfunction. Thus, it negatively influences cardiovascular risk in the general population. The aim of this review is to analyze the current, controversial, and future role of ivabradine as an anti-anginal agent in the setting of coronary artery disease without heart failure. Ivabradine represents a selective heart rate-lowering agent that increased diastolic perfusion time and improving energetics in the ischemic myocardium.

    Our objective is to explore the effect of curcumin on permeability of coronary artery and expression of related proteins in rat coronary atherosclerosis heart disease model. 45 healthy male Wistar rats of clean grade were selected and divided into treatment group, model control group and blank control group. The rats in the treatment group and model control group received high-fat diet for 12 weeks and intraperitoneal injection of VD3 to establish rat coronary atherosclerosis heart disease model. After modeling, the rats in the treatment group received gavage of 100 mg/(kg·d) curcimin, and the rats in the model control group and blank control group received gavage of 5 ml/(kg·d) distilled water, the intervention time was 4 weeks. After intervention, the rats were killed, and the hearts were dissected to obtain the samples of coronary artery. After embedding and frozen section, immunofluorescence method was used to detect the change of endarterium permeability in 3 groups, Western blot was used to detect matrix metalloproteinase-9 (MMP-9) and CD40L in coronary artery tissue, and enzyme linked immunosorbent assay (ELISA) was used to detect serum tumor necrosis factor-α (TNF-α) and C reaction protein (CRP). After modeling, compared with the blank control group, total cholesterol (TC), triglyceride (TG) and low density lipoprotein cholesterin (LDL-c) in the treatment group and model control group were significantly higher (Pcoronary artery in treatment group and model control group, indicating that the modeling was successful. Immunofluorescence showed that there was only a little fluorochrome permeability in artery in blank control group, there was some fluorochrome permeability in artery in the treatment group and there was a lot of fluorochrome permeability in artery in the model control group. MMP-9 and CD40L in coronary artery tissue in the model control group were significantly higher than the treatment group (Pcoronary artery tissue in the treatment group

    Coronary heart disease is the leading cause of death worldwide, and its incidence is rapidly accelerating in developing nations. Patients often search for therapies that are alternatives to traditional treatments, such as heart medicines, coronary bypass surgery, or coronary stenting. Ayurveda is an ancient, East Indian, holistic approach to health care, and its use has never been formally evaluated for patients with coronary heart disease. The study intended to examine the feasibility and effectiveness of comprehensive ayurvedic therapy-incorporating diet, meditation, breathing exercises, yoga, and herbs-for patients with established coronary heart disease. The study was a prospective, single-group, pilot study. The study took place at the University of New Mexico Cardiology Clinic and at the Ayurvedic Institute in Albuquerque, NM, USA. The participants were adults with a history of a prior heart attack, coronary bypass surgery, or a coronary intervention (ie, a coronary angioplasty and/or stent). All enrolled patients were evaluated by a single ayurvedic physician with >40 y of experience, and each received therapy consisting of a calorically unrestricted ayurvedic diet; instruction in yoga, meditation, and breathing; and use of ayurvedic herbs. The primary endpoint was arterial pulse wave velocity, a marker of arterial function and vascular health. Secondary endpoints included the following measurements: (1) body mass index (BMI); (2) blood pressure (BP) and amount of reduction in BP medications; and (3) levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides. All parameters were measured at baseline and after 90 d of therapy. Twenty-two patients were enrolled in the study, and 19 patients completed it. The research team observed significant improvements in arterial pulse wave velocity (P = .015), and favorable reductions in BMI (P ayurveda on arterial function and multiple risk

    The myocardium assures the supply of oxygen to the body. The provision of oxygen to the myocardium by the coronary arteries is dependent on two key parameters: the coronary blood flow and the ability to extract oxygen from the arterial blood. Coronary artery disease is almost always the consequence of atherosclerosis and can lead to myocardial infarction.

    Fatigue is a prevalent and disabling symptom associated with many acute and chronic conditions, including acute myocardial infarction and chronic heart failure. Fatigue has not been explored in patients with stable coronary heart disease (CHD). The purpose of this partially mixed sequential dominant status study was to (a) describe fatigue in patients with stable CHD; (b) determine if specific demographic (gender, age, education, income), physiological (hypertension, hyperlipidemia), or psychological (depressive symptoms) variables were correlated with fatigue; and (c) determine if fatigue was associated with health-related quality of life. The theory of unpleasant symptoms was used as a conceptual framework. Patients (N = 102) attending two cardiology clinics completed the Fatigue Symptom Inventory, Patient Health Questionnaire-9, and Medical Outcomes Study Short Form-36 to measure fatigue, depressive symptoms, and health-related quality of life. Thirteen patients whose interference from fatigue was low, moderate, or high participated in qualitative interviews. Forty percent of the sample reported fatigue more than 3 days of the week lasting more than one half of the day. Lower interference from fatigue was reported on standardized measures compared with qualitative interviews. Compared with men, women reported a higher fatigue intensity (p = .003) and more interference from fatigue (p = .007). In regression analyses, depressive symptoms were the sole predictor of fatigue intensity and interference. Patients with stable CHD reported clinically relevant levels of fatigue. Patients with stable CHD may discount fatigue as they adapt to their symptoms. Relying solely on standardized measures may provide an incomplete picture of fatigue burden in patients with stable CHD.

    We sought to compare the prevalence of coronary atherosclerosis in a cohort of middle-age African American (black) and non-Hispanic Caucasian (white) men and women from a population-based probability sample. Blacks have a higher mortality from coronary heart disease (CHD) than whites, particularly among younger individuals, and yet several studies have reported that coronary atherosclerosis is less prevalent in blacks than in whites. Data from population-based samples comparing coronary atherosclerotic burden between blacks and whites are limited. The prevalence of coronary atherosclerosis in middle-aged blacks and whites was determined using coronary calcium measured by electron beam computed tomography in 1,289 men and women from a population-based probability sample from Dallas, Texas. The population estimates of the frequency of a positive scan for coronary artery calcium were not statistically different between black and white men (37% vs. 41%, p = 0.36) or between black and white women (29% vs. 23%, p = 0.21). Although the prevalence of most of the coronary risk factors varied significantly between blacks and whites, mean Framingham coronary risk factor scores were identical in black and white men (10 +/- 4) but significantly higher in black women (13 +/- 4) than in white women (12 +/- 4). Blacks in the general population have a prevalence of coronary atherosclerosis similar to whites. Factors other than coronary atherosclerotic burden, which are not reflected in the Framingham risk score, contribute significantly to the higher CHD mortality rate in blacks.

    A technique utilizing laser induced fluorescence has been developed to obtain direct real-time imaging of the coronary artery network for open heart surgery applications. Both excimer pumped dye and cw argon-ion laser radiation transmitted through a fused silica fiber were used as laser sources to irradiate swine, bovine, and human cadaver hearts whose coronary arteries had been injected with strongly fluorescent dyes. The laser induces fluorescence originating from within the coronary arteries and detected by the surgeon's eye, allows the entire coronary network to be directly viewed. A comparison between laser induced fluorescence and the use of direct visual inspection of arteries following injection of the dye Cardio-Green(R) as well as conventional thermal imaging is presented. The limitations imposed on each technique by layers of fat on top of the coronary arteries are also described. The possibility of using these techniques to detect mechanical or laser beam perforations during laser endarterectomy procedures is discussed.

    In humans, taurine (2-aminoethanesulfonic acid) is mainly obtained from diet. Despite the fact that the health effects of taurine are largely unknown, taurine has become a popular supplement and ingredient in energy drinks in recent years. Evidence from mechanistic and animal studies has shown that the main biological actions of taurine include its ability to conjugate bile acids, regulate blood pressure (BP), and act as a potent antioxidant and anti-inflammatory agent. These actions suggest that high levels of taurine may be protective against coronary heart disease (CHD). However, data from epidemiologic and intervention studies in humans are limited. We review what is known about taurine's metabolism, its transportation in the body, its food sources, and evidence of its effect on cardiovascular health from in vitro, animal, and epidemiologic studies. We also discuss shortcomings of the human studies that need to be addressed in the future. The identification of taurine as a preventive factor for CHD may be of great public health importance.

    Full Text Available Inflammation is widely considered to be an important contributing factor of the pathophysiology of coronary heart disease (CHD, and the inflammatory cascade is particularly important in the atherosclerotic process. In consideration of the important role that inflammatory processes play in CHD, recent work has been focused on whether biomarkers of inflammation may help to improve risk stratification and identify patient groups who might benefit from particular treatment strategies. Of these biomarkers, C-reactive protein (CRP has emerged as one of the most important novel inflammatory markers. CRP an acute phase protein is synthesized by hepatocytes in response to proinflammatory cytokines, in particular interleukin-6. Many large-scale prospective studies demonstrate that CRP strongly and independently predicts adverse cardiovascular events, including myocardial infarction, ischemic stroke, and sudden cardiac death in individuals both with and without overt CHD. CRP is believed to be both a marker and a mediator of atherosclerosis and CHD. CRP plays a pivotal role in many aspects of atherogenesis including, activation of complement pathway, lipids uptake by macrophage, release of proinflammatory cytokines, induces the expression of tissue factor in monocytes, promotes the endothelial dysfunction and inhibits nitric oxide production. The commercial availability of CRP high sensitive assays has made screening for this marker simple, reliable, and reproducible and can be used as a clinical guide to diagnosis, management, and prognosis of CHD.

    Many individuals with coronary heart disease (CHD) experience disease-related anxiety, depressive symptoms, and anger. Spirituality may be helpful to cope with these negative emotions. Research findings on the role of spirituality in dealing with negative emotions are inconsistent. In this study, we examined the associations between 7 dimensions of spirituality (ie, meaningfulness, trust, acceptance, caring for others, connectedness with nature, transcendent experiences, and spiritual activities) and negative emotions among individuals with CHD in Indonesia, controlling for perceived social support as well as demographic and clinical characteristics. In total, 293 individuals with CHD were recruited from the 3 largest hospitals in Bandung, Indonesia. They completed the Spiritual Attitude and Involvement List, the Beck Depression Inventory-II, the Trait Anxiety Scale of the State Trait Anxiety Inventory, the Multidimensional Anger Inventory, and the Multidimensional Scale of Perceived Social Support. Hierarchical linear regression analyses indicated that a higher overall level of spirituality was associated with lower levels of depressive symptoms, less anxiety, and less anger. Specifically, a higher level of trust was significantly associated with both less depressive symptoms and less anxiety. Higher levels of caring for others and spiritual activities were associated with less anxiety, and a higher level of connectedness with nature was associated with less anger. These findings underscore the importance of specific dimensions of spirituality as a potentially independent buffer against negative emotions in individuals with CHD.

    Cardiovascular disease (CVD) is now the leading cause of morbidity and mortality worldwide. Industrialization and economic growth have led to an unprecedented increment in the burden of CVD and their risk factors in less industrialized regions of the world. While there are abundant data on CVD and their risk factors from longitudinal cohort studies done in the West, good-quality data from South Asia are lacking. Several multi-institutional, observational, prospective registries, and epidemiologic cohorts in South Asia have been established to systematically evaluate the burden of CVD and their risk factors. The PINNACLE (Practice Innovation and Clinical Excellence) India Quality Improvement Program (PIQIP), the Kerala Acute Coronary Syndrome (ACS), and Trivandrum Heart Failure registries have focused on secondary prevention of CVD and performance measurement in both outpatient and inpatient settings, respectively. The Prospective Urban and Rural Epidemiology (PURE), Centre for Cardiometabolic Risk Reduction in South Asia (CARRS), and other epidemiologic and genetic studies have focused on primary prevention of CVD and evaluated variables such as environment, smoking, physical activity, health systems, food and nutrition policy, dietary consumption patterns, socioeconomic factors, and healthy neighborhoods. The international cardiovascular community has been responsive to a burgeoning cardiovascular disease burden in South Asia. Several collaborations have formed between the West (North America in particular) and South Asia to catalyze evidence-based and data-driven changes in the federal health policy in this part of the world to promote cardiovascular health and mitigate cardiovascular risk.

    To investigate the association of employment status with coronary heart disease (CHD) and ischemic stroke among middle-aged women. Proportional hazards regression was used to assess the association of employment status, incident CHD, and incident ischemic stroke among 7,058 women, ages 45-64 years at baseline (1987-1989), from the Atherosclerosis Risk in Communities Study. After adjusting for age and race-field center, women employed outside the home had a decreased risk of CHD (hazard ratio [HR], 0.70; 95% confidence interval [95% CI], 0.56-0.86) and ischemic stroke (HR, 0.62; 95% CI, 0.47-0.84) compared with homemakers. Differences in cardiovascular disease risk factors partially accounted for the association of employment status and CHD (HR, 0.79; 95% CI, 0.63-0.99) and stroke (HR, 0.79; 95% CI, 0.58-1.08). Also, modest differences were noted when the results were stratified by education, with employed women having a lower risk of CHD (HR, 0.65; 95% CI, 0.45-0.93) than homemakers among those with less than a high school education. Women employed outside of the home had a lower risk of CHD and stroke compared with homemakers and, for CHD, this association was stronger among women with less than a high school education. These findings suggest additional research into the varied occupational experiences of women, socioeconomic status, and health is warranted.

    Data from epidemiologic studies document the role of clinically manifest diabetes mellitus as a powerful risk determinant for an array of atherosclerotic cardiovascular outcomes including coronary heart disease (CHD), stroke, and peripheral arterial disease, particularly in the elderly. Although dyslipidemias and hypertension are quite prevalent in persons with diabetes mellitus and contribute heavily to the underlying atherosclerotic process, other factors involving alternative pathogenetic mechanisms are necessary to explain for the dramatic acceleration of atherogenesis observed in this condition. Myocardial ischemia may be silent and myocardial infarction (MI) may be either painless or atypical in presentation which further complicates both the diagnostic and therapeutic management of CHD in older diabetic patients. MI, in this context, is confounded by dual prognostic disadvantages of higher risk for MI-related complications attributable to both advanced age and diabetes mellitus. Because available evidence has yet to demonstrate that control of hyperglycemia, either by oral agents or by insulin, effectively forestalls either the development or complications of atherosclerosis, preventive management in older patients with diabetes requires critical attention to correcting coexisting cardiovascular risk factors.

    Nowadays periodontitis--etiologically linked with bacterial flora, mainly anaerobic--is very often pointed out as one of potential risk factors for coronary heart disease (CHD) and myocardial infarction. Only few Polish publications on this subject are available. The aim of this study was to evaluate the frequency and degree of advancement of periodontitis among patients with CHD and after myocardial infarction, hospitalized in I Clinic of Cardiology, Medical University in Gdansk, Poland. Simultaneously an attempt to answer the question, if periodontitis can be a potential risk factor for CHD and myocardial infarction in Poland's population. 104 patients, aged 43-80 (average 60 years) were examined--57 persons after myocardial infarction (group I) and 47 persons with CHD without acute events (group II). Anamnesis and clinical examination using WHO recommended parameters (API, SBI, PD, CAL, CPITN) were performed. In 82.4% patients of group I and 72.2% of group II periodontitis was diagnosed. This percentage was significantly higher in comparison with general population. Advancement of destructive lesions suggests long duration of disease and it's possible negative influence on general health status. The results indicate possible link between periodontal infection's foci and CHD, and also show, that education, prevalence and treatment program for this population should be created.

    Full Text Available Abstract Background Socioeconomic status (SES predicts coronary heart disease independently of the traditional risk factors included in the Framingham risk score. However, it is unknown whether changes in Framingham risk score variables over time explain the association between SES and coronary heart disease. We examined this question given its relevance to risk assessment in clinical decision making. Methods The Atherosclerosis Risk in Communities study data (initiated in 1987 with 10-years follow-up of 15,495 adults aged 45-64 years in four Southern and Mid-Western communities were used. SES was assessed at baseline, dichotomized as low SES (defined as low education and/or low income or not. The time dependent variables - smoking, total and high density lipoprotein cholesterol, systolic blood pressure and use of blood pressure lowering medication - were assessed every three years. Ten-year incidence of coronary heart disease was based on EKG and cardiac enzyme criteria, or adjudicated death certificate data. Cox survival analyses examined the contribution of SES to heart disease risk independent of baseline Framingham risk score, without and with further adjustment for the time dependent variables. Results Adjusting for baseline Framingham risk score, low SES was associated with an increased coronary heart disease risk (hazard ratio [HR] = 1.53; 95% Confidence Interval [CI], 1.27 to1.85. After further adjustment for the time dependent variables, the SES effect remained significant (HR = 1.44; 95% CI, 1.19 to1.74. Conclusion Using Framingham Risk Score alone under estimated the coronary heart disease risk in low SES persons. This bias was not eliminated by subsequent changes in Framingham risk score variables.

    Microcirculation disturbances have been associated to most of the cardiovascular risk factors as well as to multiple inflammatory diseases. However, whether these abnormalities are specifically augmented in patients with coronary heart disease is still unknown. We aimed to evaluate if there is a relationship between the presence of coronary heart disease and the existence of functional and structural capillary abnormalities evaluated in the cutaneous microcirculation by videocapillaroscopy. Two matched samples of 30 participants with and without coronary heart disease but with similar clinical and anthropometric characteristics were evaluated by videocapillaroscopy at the dorsal skin of the third finger of the non-dominant hand. We calculated basal capillary density as well as capillary density after a period of arterial and venous occlusion in order to evaluate functionality and maximum capillary density. We also measured capillary recruitment. Microvascular capillary density at rest was significantly lower in patients suffering from coronary heart disease than in controls. This fact was also found after dynamic tests (arterial and venous occlusion), suggesting functional impairments. Capillary recruitment of the samples was not different in our sample. In our study, patients with coronary heart disease exhibit functional and structural microvascular disturbances. Although this is a very preliminary study, these findings open the door for further studying the microvascular functionality in coronary patients and how it relates to the response to treatment and/or the prognosis of the disease.

    Full Text Available Coronary dominance in swine has been poorly evaluated. The frequencies of each type of dominance have been described, but few details have been given as to the different expressions of each one. The aim of this study was to characterize coronary dominance in commercial breed swine. One hundred and fifty eight pig hearts were evaluated. The coronary arteries (CA were infused with synthetic resin (Palatal 85% and Styrene15% through the ostia after channeling. The coronary artery that gives origin to the posterior interventricular artery (PIA, and the site of termination of both the circumflex arteries (CXA, and left retroventricular branch (LRVB were determined in order to establish the coronary dominance pattern. Right coronary dominance was found in 105 hearts (66.5%, and a balanced circulation in 53 specimens (33.5%. No dominance was observed for the left coronary artery in the hearts studied. The CXA ended on the posterior aspect of the left ventricle in 101 samples (64% and on the crux cordis in 55 specimens (34.8%. In two specimens (1.3% it ended as a left marginal artery. In all cases the PIA was a branch of the RCA, and was long in 105 hearts (66%, 55% of which corresponded to males and 45% to females, but this difference was not statistically significant (p=0.77. The AIA ended on the apex in 126 specimens (80%, 71 of which (56% corresponded to males and 55 (44% to females (p=0.74. Regarding right coronary dominance, subtype I was observed in 98 specimens (93.3%, subtype II in 5 cases (4.8%, whereas subtype III was observed in 2 hearts (1.9%. Knowing coronary dominance patterns and their irrigation territories is useful for training purposes based on the use of experimental and hemodynamic models with this animal species.

    The number one cause of death in the U.S. is coronary heart disease (CHD). It is probably a major cause of death and disability in the lives of employees at Kennedy Space Center (KSC) as well. The KSC Biomedical Office used a multifactorial mathematical formula from the Framingham Heart Study to calculate CHD risk probabilities for individuals in a segment of the KSC population that required medical evaluation for job certification. Those assessed to be high-risk probabilities will be targeted for intervention. Every year, several thousand KSC employees require medical evaluations for job related certifications. Most medical information for these evaluations is gathered on-site at one of the KSC or Cape Canaveral Air Station (CCAS) medical clinics. The formula used in the Framingham Heart Study allows calculation of a person's probability of acquiring CHD within 10 years. The formula contains the following variables: Age, Diabetes, Smoking, Left Ventricular Hypertrophy, Blood Pressure (Systolic or Diastolic), Cholesterol, and HDL cholesterol. The formula is also gender specific. It was used to calculate the 10-year probabilities of CHD in KSC employees who required medical evaluations for job certifications during a one-year time frame. This KSC population was profiled and CHD risk reduction interventions could be targeted to those at high risk. Population risk could also be periodically reevaluated to determine the effectiveness of intervention. A 10-year CHD risk probability can be calculated for an individual quite easily while gathering routine medical information. An employee population's CHD risk probability can be profiled graphically revealing high risk segments of the population which can be targeted for risk reduction intervention. The small audience of NASA/contractor physicians, nurses and exercise/fitness professionals at the breakout session received the lecture very well. Approximately one third indicated by a show of hands that they would be

  18. Whole heart coronary imaging with flexible acquisition window and trigger delay.

    Directory of Open Access Journals (Sweden)

    Keigo Kawaji

    Full Text Available Coronary magnetic resonance imaging (MRI requires a correctly timed trigger delay derived from a scout cine scan to synchronize k-space acquisition with the quiescent period of the cardiac cycle. However, heart rate changes between breath-held cine and free-breathing coronary imaging may result in inaccurate timing errors. Additionally, the determined trigger delay may not reflect the period of minimal motion for both left and right coronary arteries or different segments. In this work, we present a whole-heart coronary imaging approach that allows flexible selection of the trigger delay timings by performing k-space sampling over an enlarged acquisition window. Our approach addresses coronary motion in an interactive manner by allowing the operator to determine the temporal window with minimal cardiac motion for each artery region. An electrocardiogram-gated, k-space segmented 3D radial stack-of-stars sequence that employs a custom rotation angle is developed. An interactive reconstruction and visualization platform is then employed to determine the subset of the enlarged acquisition window for minimal coronary motion. Coronary MRI was acquired on eight healthy subjects (5 male, mean age = 37 ± 18 years, where an enlarged acquisition window of 166-220 ms was set 50 ms prior to the scout-derived trigger delay. Coronary visualization and sharpness scores were compared between the standard 120 ms window set at the trigger delay, and those reconstructed using a manually adjusted window. The proposed method using manual adjustment was able to recover delineation of five mid and distal right coronary artery regions that were otherwise not visible from the standard window, and the sharpness scores improved in all coronary regions using the proposed method. This paper demonstrates the feasibility of a whole-heart coronary imaging approach that allows interactive selection of any subset of the enlarged acquisition window for a tailored reconstruction

    Importance Kidney stone disease is common and may be associated with an increased risk of coronary heart disease (CHD). However, previous studies of the association between kidney stones and CHD have often not controlled for important risk factors, and the results have been inconsistent. Objective We examined the association between a history of kidney stones and the risk of CHD in three large prospective cohorts. Design, setting, and participants Prospective study of 45,748 men and 196,357 women in the United States without a history of CHD at baseline who were participants in the Health Professionals Follow-Up Study (HPFS, 51,529 men aged 40–75 years followed since 1986), Nurses’ Health Study (NHS) I (121,700 women aged 30–55 years followed since 1976) and II (116,430 women aged 25–42 years followed since 1989). The diagnoses of kidney stones and CHD were updated biennially during follow-up. Main outcome measure CHD was defined as fatal or non-fatal myocardial infarction (MI) or coronary revascularization. The outcome was identified by biennial questionnaires and confirmed through review of medical records (fatal and non-fatal MI). Results Out of a total of 242,105 participants, 19,678 reported a history of kidney stones. After up to 24 years of follow-up in men and 18 years in women, 16,838 incident cases of CHD occurred. After adjusting for potential confounders, among women, those with a reported history of kidney stones compared with those without had an increased risk of CHD in NHS I (incidence rate (IR) 754 vs 514/100,000 person-years; multivariate HR 1.18, 95% CI 1.08 to 1.28) and NHS II (IR 144 vs 55/100,000 person-years; multivariate HR 1.48, 95% CI 1.23 to 1.78); there was no significant association in men (IR 1,355 vs 1,022/100,000 person-years; multivariate HR 1.06, 95% CI 0.99 to 1.13). Similar results were found when analyzing the individual end-points (fatal and non-fatal MI, revascularization). Conclusions Among two cohorts of women, a

    1997-01-01

    From this detailed analysis of the main dietary trials conducted over the last 30 years in the secondary prevention of coronary heart disease, it can be said that the older trials were conducted on low risk patients and used high fat diets (about 40% of energy as lipids), comprising low saturated fat and cholesterol intake but very high (15 to 20% of energy) polyunsaturated fat intake, particularly from the omega-6 fatty acid family. These experimental diets were designed to reduce blood cholesterol and failed to improve prognosis. By contrast, recent trials were not primarily designed to reduce cholesterol, were conducted in medium- and high-risk patients and used low fat diets supplemented by omega-3 fatty acids from various sources. In two of these trials, the consumption of natural antioxidants, oligoelements and vegetable proteins was increased. Recurrence rate was reduced in the range of 30 to 70%. One conclusion from these well-conducted recent experiments on more than 3000 patients is that new and more specific dietary recommendations are clearly warranted in secondary prevention of coronary heart disease. They should be more specific and more clearly defined and therefore different from those generally provided in the U.S.A. and Europe at present. In a recent Consensus Panel statement, authors wrote less than one line to describe a cardioprotective diet in patients with coronary heart disease, summarized as fat, fat, fats maintain intake at least minimally, of the essential omega-6 fatty acids augment consumption of oleic acid and moderately increase consumption of omega-3 fatty acids augment intake of natural antioxidants and oligo-elements maintain sufficient intake of vegetable proteins As conceptualized in the 'Mediterranean' and 'Asian-vegetarian' types of diet, it is very important that a healthy diet should be thought of as a whole rather than as a recitation of good and bad components. Although these protective dietary modifications should probably

    Risk factor screening and establishing realistic goals are key steps for the dietitian to follow in planning strategies to prevent coronary heart disease. The major risk factors that are responsive to dietary intervention include: elevated plasma total cholesterol and low-density-lipoprotein cholesterol, elevated blood pressure, glucose intolerance, and obesity. The criteria used in assessing nutrition-related risk in coronary heart disease are presented. The long-term goals of preventive nutrition intervention in heart disease are discussed, with emphasis on a unified and progressive approach to diet planning.

    This study analyzes the U.S. 2006 Behavioral Risk Factor Surveillance System survey data (N = 235,783) to test whether self-reported cardiovascular disease rates are higher in Appalachian coal mining counties compared to other counties after control for other risks. Dependent variables include self-reported measures of ever (1) being diagnosed with cardiovascular disease (CVD) or with a specific form of CVD including (2) stroke, (3) heart attack, or (4) angina or coronary heart disease (CHD). Independent variables included coal mining, smoking, BMI, drinking, physician supply, diabetes co-morbidity, age, race/ethnicity, education, income, and others. SUDAAN Multilog models were estimated, and odds ratios tested for coal mining effects. After control for covariates, people in Appalachian coal mining areas reported significantly higher risk of CVD (OR = 1.22, 95% CI = 1.14-1.30), angina or CHO (OR = 1.29, 95% C1 = 1.19-1.39) and heart attack (OR = 1.19, 95% C1 = 1.10-1.30). Effects were present for both men and women. Cardiovascular diseases have been linked to both air and water contamination in ways consistent with toxicants found in coal and coal processing. Future research is indicated to assess air and water quality in coal mining communities in Appalachia, with corresponding environmental programs and standards established as indicated.

Effects were present for both men and women. Cardiovascular diseases have been linked to both air and water contamination in ways consistent with toxicants found in coal and coal processing. Future research is indicated to assess air and water quality in coal mining communities in Appalachia, with corresponding environmental programs and standards established as indicated.

    Full Text Available BACKGROUND: Coronary heart disease (CHD mortality rates have been decreasing in Iceland since the 1980s, largely reflecting improvements in cardiovascular risk factors. The purpose of this study was to predict future CHD mortality in Iceland based on potential risk factor trends. METHODS AND FINDINGS: The previously validated IMPACT model was used to predict changes in CHD mortality between 2010 and 2040 among the projected population of Iceland aged 25-74. Calculations were based on combining: i data on population numbers and projections (Statistics Iceland, ii population risk factor levels and projections (Refine Reykjavik study, and iii effectiveness of specific risk factor reductions (published meta-analyses. Projections for three contrasting scenarios were compared: (1 If the historical risk factor trends of past 30 years were to continue, the declining death rates of past decades would level off, reflecting population ageing. (2 If recent trends in risk factors (past 5 years continue, this would result in a death rate increasing from 49 to 70 per 100,000. This would reflect a recent plateau in previously falling cholesterol levels and recent rapid increases in obesity and diabetes prevalence. 3 Assuming that in 2040 the entire population enjoys optimal risk factor levels observed in low risk cohorts, this would prevent almost all premature CHD deaths before 2040. CONCLUSIONS: The potential increase in CHD deaths with recent trends in risk factor levels is alarming both for Iceland and probably for comparable Western populations. However, our results show considerable room for reducing CHD mortality. Achieving the best case scenario could eradicate premature CHD deaths by 2040. Public health policy interventions based on these predictions may provide a cost effective means of reducing CHD mortality in the future.

    Coronary heart disease (CHD) will continue to exert a heavy burden for countries all over the world. Scientific collaboration has become the only choice for progress in biomedicine. Unfortunately, there is a scarcity of scientific publications about scientific collaboration in CHD research. This study examines collaboration behaviors across multiple collaboration types in the CHD research. 294,756 records about CHD were retrieved from Web of Science. Methods such as co-authorship, social network analysis, connected component, cliques, and betweenness centrality were used in this study. Collaborations have increased at the author, institution and country/region levels in CHD research over the past three decades. 3000 most collaborative authors, 572 most collaborative institutions and 52 countries/regions are extracted from their corresponding collaboration network. 766 cliques are found in the most collaborative authors. 308 cliques are found in the most collaborative institutions. Western countries/regions represent the core of the world's collaboration. The United States ranks first in terms of number of multi-national publications, while Hungary leads in the ranking measured by their proportion of collaborative output. The rate of economic development in the countries/regions also affects the multi-national collaboration behavior. Collaborations among countries/regions need to be encouraged in the CHD research. The visualization of overlapping cliques in the most collaborative authors and institutions are considered "skeleton" of the collaboration network. Eastern countries/regions should strengthen cooperation with western countries/regions in the CHD research. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    OBJECTIVE--To assess the safety and value of an exercise electrocardiography service for the diagnosis of suspected ischaemic heart disease to which general practitioners have direct access. DESIGN--Direct access to a hospital exercise electrocardiography service was offered on a trial basis to 122 general practitioners in a defined urban area. Maximal exercise tests were performed according to the modified Bruce protocol and the results were dispatched promptly to the referring doctors who were responsible for the subsequent management of their patients. SETTING--All general practices in north and west Belfast (combined list size about 180,000) and the regional medical cardiology centre. PATIENTS--212 request forms were received in a two year period and 192 eligible patients attended for exercise testing. All patients were suspected to have pain due to myocardial ischaemia, were aged electrocardiography for patients with suspected ischaemic heart disease is safe, feasible, and helpful to general practitioners. This service seems to reduce the number of patients referred to cardiology outpatient clinics and to facilitate the management of these patients in the community. PMID:8043332

    This article is devoted to the problems of diagnostics of coronary artery tortuosity phenomenon. Given the lack of literature about the role of phenomenon tortuosity of coronary arteries in the genesis of ischemic myocardial damage, the purpose of study was to determine the clinical relevance as well as necessity for prevention and treatment of this vascular anomaly. Therefore were analyzed medical history, laboratory and clinical database as well as data functional studies of the heart and cardiovascular system in 1404 patients which were divided into four groups on the results of coronary angiography. The results of the study indicate tortuosity of coronary arteries may be independent and additional burdening factor in the development of ischemic heart disease.

    Full Text Available Abstract Background Cardiopulmonary bypass (CPB with aortic cross-clamping and cardioplegic arrest remains the method of choice for patients requiring standard myocardial revascularization. Therefore, very high-risk patients presenting with acute coronary syndrome, unstable angina, onset of cardiac decompensation and requiring emergency multiple myocardial revascularization, can have a poor outcome. The on-pump beating heart technique can reduce the mortality and the morbidity in such a selected group of patients and this report describes our clinical experience. Methods Out of 290 patients operated for CABG from January 2005 to January 2006, 25 (8.6% selected high-risk patients suffering from life threatening coronary syndrome (mean age 69 ± 7 years and requiring emergency multiple myocardial revascularization, underwent on-pump beating heart surgery. The mean pre-operative left ventricle ejection fraction (LVEF was 27 ± 8%. The majority of them (88% suffered of tri-vessel coronary disease and 6 (24% had a left main stump disease. Nine patients (35% were on severe cardiac failure and seven among them (28% received a pre-operative intra-aortic balloon pump. The pre-operative EuroScore rate was equal or above 8 in 18 patients (73%. Results All patients underwent on-pump-beating heart coronary revascularization. The mean number of graft/patient was 2.9 ± 0.6 and the internal mammary artery was used in 23 patients (92%. The mean CPB time was 84 ± 19 minutes. Two patients died during the recovery stay in the intensive care unit, and there were no postoperative myocardial infarctions between the survivors. Eight patients suffered of transitorily renal failure and 1 patient developed a sternal wound infection. The mean hospital stay was 12 ± 7 days. The follow-up was complete for all 23 patients survived at surgery and the mean follow-up time was 14 ± 5 months. One patient died during the follow-up for cardiac arrest and 2 patients required an

    Summary Background Increased circulating plasma urate concentration is associated with an increased risk of coronary heart disease, but the extent of any causative effect of urate on risk of coronary heart disease is still unclear. In this study, we aimed to clarify any causal role of urate on coronary heart disease risk using Mendelian randomisation analysis. Methods We first did a fixed-effects meta-analysis of the observational association of plasma urate and risk of coronary heart disease. We then used a conventional Mendelian randomisation approach to investigate the causal relevance using a genetic instrument based on 31 urate-associated single nucleotide polymorphisms (SNPs). To account for potential pleiotropic associations of certain SNPs with risk factors other than urate, we additionally did both a multivariable Mendelian randomisation analysis, in which the genetic associations of SNPs with systolic and diastolic blood pressure, HDL cholesterol, and triglycerides were included as covariates, and an Egger Mendelian randomisation (MR-Egger) analysis to estimate a causal effect accounting for unmeasured pleiotropy. Findings In the meta-analysis of 17 prospective observational studies (166 486 individuals; 9784 coronary heart disease events) a 1 SD higher urate concentration was associated with an odds ratio (OR) for coronary heart disease of 1·07 (95% CI 1·04–1·10). The corresponding OR estimates from the conventional, multivariable adjusted, and Egger Mendelian randomisation analysis (58 studies; 198 598 individuals; 65 877 events) were 1·18 (95% CI 1·08–1·29), 1·10 (1·00–1·22), and 1·05 (0·92–1·20), respectively, per 1 SD increment in plasma urate. Interpretation Conventional and multivariate Mendelian randomisation analysis implicates a causal role for urate in the development of coronary heart disease, but these estimates might be inflated by hidden pleiotropy. Egger Mendelian randomisation analysis, which accounts for

    Background and Aims Epidemiologic studies have suggested beneficial effects of flavonoids on cardiovascular disease. Cocoa and particularly dark chocolate are rich in flavonoids and recent studies have demonstrated blood pressure lowering effects of dark chocolate. However, limited data are available on the association of chocolate consumption and the risk of coronary heart disease (CHD). We sought to examine the association between chocolate consumption and prevalent CHD. Methods We studied in a cross-sectional design 4,970 participants aged 25 to 93 years who participated in the National Heart, Lung, and Blood Institute (NHLBI) Family Heart Study. Chocolate intake was assessed through a semi-quantitative food frequency questionnaire. We used generalized estimating equations to estimate adjusted odds ratios. Results Compared to subjects who did not report any chocolate intake, odds ratios (95% CI) for CHD were 1.01 (0.76-1.37), 0.74 (0.56-0.98), and 0.43 (0.28-0.67) for subjects consuming 1-3 times/month, 1-4 times/week, and 5+ times/week, respectively (p for trend chocolate candy intake, linolenic acid intake, smoking, alcohol intake, exercise, and fruit and vegetables. Consumption of non-chocolate candy was associated with a 49% higher prevalence of CHD comparing 5+/week vs. 0/week [OR=1.49 (0.96-2.32)]. Conclusions These data suggest that consumption of chocolate is inversely related with prevalent CHD in a general population. PMID:20858571

    Full Text Available The coronary heart disease is one of desease leading to the sudden death. This is the reason why online monitoring system is urgently needed to monitor the patients with coronary heart disease. This paper proposse the system with an algorithm which is developed from signal identification of ST elevation. The medical record in this system is measured by a new wireless ECG development and followed Zigbee standard. If the system detects the possibility of disturbance in cardiac function, then soon, an alarm signal is send to the server at the hospital, in order that an intensive first aid can be given immediately. Based on the testing results, the level of success of an online monitoring system is possible to reach 100% if the patient does not make any moving around. It is expected that the application of this system will reduce the sudden death for patients at hospital with coronary heart disease.

    Full Text Available Coronary arterial fistulas are rare communications between vessels or chambers of the heart. Although cardiac symptoms associated with fistulas are well described, fistulas are seldom considered in the differential diagnosis of acute myocardial ischemia. We describe the case of a 64-year-old man who presented with left shoulder pain, signs of heart failure, and a new left bundle branch block (LBBB. Cardiac catheterization revealed a small left anterior descending (LAD-to-pulmonary artery (PA fistula. Diuresis led to subjective improvement of the patient's symptoms and within several days the LBBB resolved. We hypothesize that the coronary fistula in this patient contributed to transient ischemia of the LAD territory through a coronary steal mechanism. We elected to observe rather than repair the fistula, as his symptoms and ECG changes resolved with treatment of his heart failure.

    Coronary heart disease is a major cause of heart failure. Availability of risk-prediction models that include both clinical parameters and biomarkers is limited. We aimed to develop such a model for prediction of incident heart failure. A multivariable risk-factor model was developed for prediction of first occurrence of heart failure death or hospitalization. A simplified risk score was derived that enabled subjects to be grouped into categories of 5-year risk varying from 20%. Among 7101 patients from the LIPID study (84% male), with median age 61years (interquartile range 55-67years), 558 (8%) died or were hospitalized because of heart failure. Older age, history of claudication or diabetes mellitus, body mass index>30kg/m(2), LDL-cholesterol >2.5mmol/L, heart rate>70 beats/min, white blood cell count, and the nature of the qualifying acute coronary syndrome (myocardial infarction or unstable angina) were associated with an increase in heart failure events. Coronary revascularization was associated with a lower event rate. Incident heart failure increased with higher concentrations of B-type natriuretic peptide >50ng/L, cystatin C>0.93nmol/L, D-dimer >273nmol/L, high-sensitivity C-reactive protein >4.8nmol/L, and sensitive troponin I>0.018μg/L. Addition of biomarkers to the clinical risk model improved the model's C statistic from 0.73 to 0.77. The net reclassification improvement incorporating biomarkers into the clinical model using categories of 5-year risk was 23%. Adding a multibiomarker panel to conventional parameters markedly improved discrimination and risk classification for future heart failure events. Copyright © 2017 Elsevier Ireland Ltd.

    Aim: To evaluate the prevalence of coronary artery disease (CAD) in relation to risk of coronary heart disease (CHD) and assess plaque characteristics from coronary computed tomography (CT) angiography in asymptomatic and symptomatic patients. Materials and methods: Three hundred and ninety consecutive patients [asymptomatic group, n = 138; symptomatic group (atypical or non-anginal chest pain), n = 252] were retrospectively enrolled. They were subsequently classified into three CHD risk categories, based on the National Cholesterol Education Program guidelines, and 10 year risks of coronary events were calculated using Framingham risk score. CT was evaluated for stenosis, plaque composition, and coronary calcium scores. Results: CAD was observed in 42% of the asymptomatic group and 62% of the symptomatic group. In the former, the prevalence of CAD in low-, moderate- and high-risk subgroups was 21.4, 47.4 and 65%, respectively, and was 33.3, 74.4, and 72.4% in the symptomatic group. Framingham 10-year risks of coronary events were significantly higher in patients with CAD than in normal participants, and receiver operating characteristics curves showed that discriminatory power was poor in the asymptomatic group and symptomatic men, and good in symptomatic women. Of the participants in the asymptomatic group, 12% exhibited only non-calcified plaques and of the symptomatic group, 7% exhibited only non-calcified plaques. The coronary calcium score was significantly higher for significant stenosis than for non-significant stenosis in both groups. Conclusions: The prevalence of CAD was not negligible even in subgroups with low-to-moderate CHD risk. Additionally, the Framingham risk score was effective for predicting CAD only in symptomatic women. Coronary calcium scores correlated with significant stenosis; however, a sizeable percentage of both groups had only non-calcified plaques.

    To determine the association between alcohol drinking patterns and risk of coronary heart disease in women and men. Population based cohort study. Denmark, 1993-2002. 28 448 women and 25 052 men aged 50-65 years, who were free of cardiovascular disease at entry to the study. Incidence of coronary heart disease occurring during a median follow-up period of 5.7 years. 749 and 1283 coronary heart disease events occurred among women and men. Women who drank alcohol on at least one day a week had a lower risk of coronary heart disease than women who drank alcohol on less than one day a week. Little difference was found, however, between drinking frequency: one day a week (hazard ratio 0.64, 95% confidence interval 0.51 to 0.81), 2-4 days a week (0.63, 0.52 to 0.77), five or six days a week (0.79, 0.61 to 1.03), and seven days a week (0.65, 0.51 to 0.84). For men an inverse association was found between drinking frequency and risk of coronary heart disease across the entire range of drinking frequencies. The lowest risk was observed among men who drank daily (0.59, 0.48 to 0.71) compared with men who drank alcohol on less than one day a week. Among women alcohol intake may be the primary determinant of the inverse association between drinking alcohol and risk of coronary heart disease whereas among men, drinking frequency, not alcohol intake, seems more important.

    Full Text Available Abstract Background Magnitudes, geographic and racial variation in trends in coronary heart disease (CHD mortality within the US require updating for health services and health disparities research. Therefore the aim of this study is to present data on these trends through 2007. Methods Data for CHD were analyzed using the US mortality files for 1999–2007 obtained from the US Centers for Disease Control and Prevention. Age-adjusted annual death rates were computed for non-Hispanic African Americans (AA and European Americans (EA aged 35–84 years. The direct method was used to standardize rates by age, using the 2000 US standard population. Joinpoint regression models were used to evaluate trends, expressed as annual percent change (APC. Results For both AA men and women the magnitude in CHD mortality is higher compared to EA men and women, respectively. Between 1999 and 2007 the rate declined both in AA and in EA of both sexes in every geographic division; however, relative declines varied. For example, among men, relative average annual declines ranged from 3.2% to 4.7% in AA and from 4.4% to 5.5% in EA among geographic divisions. In women, rates declined more in later years of the decade and in women over 54 years. In 2007, age-adjusted death rate per 100,000 for CHD ranged from 93 in EA women in New England to 345 in AA men in the East North Central division. In EA, areas near the Ohio and lower Mississippi Rivers had above average rates. Disparities in trends by urbanization level were also found. For AA in the East North Central division, the APC was similar in large central metro (−4.2, large fringe metro (−4.3, medium metro urbanization strata (−4.4, and small metro (−3.9. APC was somewhat higher in the micropolitan/non-metro (−5.3, and especially the non-core/non-metro (−6.5. For EA in the East South Central division, the APC was higher in large central metro (−5.3, large fringe metro (−4.3 and medium metro

    To investigate the causal role of high-density lipoprotein cholesterol (HDL-C) and triglycerides in coronary heart disease (CHD) using multiple instrumental variables for Mendelian randomization. We developed weighted allele scores based on single nucleotide polymorphisms (SNPs) with established associations with HDL-C, triglycerides, and low-density lipoprotein cholesterol (LDL-C). For each trait, we constructed two scores. The first was unrestricted, including all independent SNPs associated with the lipid trait identified from a prior meta-analysis (threshold P Mendelian randomization meta-analyses were conducted in 17 studies including 62,199 participants and 12,099 CHD events. Both the unrestricted and restricted allele scores for LDL-C (42 and 19 SNPs, respectively) associated with CHD. For HDL-C, the unrestricted allele score (48 SNPs) was associated with CHD (OR: 0.53; 95% CI: 0.40, 0.70), per 1 mmol/L higher HDL-C, but neither the restricted allele score (19 SNPs; OR: 0.91; 95% CI: 0.42, 1.98) nor the unrestricted HDL-C allele score adjusted for triglycerides, LDL-C, or statin use (OR: 0.81; 95% CI: 0.44, 1.46) showed a robust association. For triglycerides, the unrestricted allele score (67 SNPs) and the restricted allele score (27 SNPs) were both associated with CHD (OR: 1.62; 95% CI: 1.24, 2.11 and 1.61; 95% CI: 1.00, 2.59, respectively) per 1-log unit increment. However, the unrestricted triglyceride score adjusted for HDL-C, LDL-C, and statin use gave an OR for CHD of 1.01 (95% CI: 0.59, 1.75). The genetic findings support a causal effect of triglycerides on CHD risk, but a causal role for HDL-C, though possible, remains less certain. © The Author 2014.

  3. Noninvasive assessment of coronary microvascular function in women at risk for ischaemic heart disease.

    The primary objective of the current review is to describe the assessment of coronary microvascular function by noninvasive imaging techniques in women at risk for and with ischaemic heart disease (IHD). The search criteria were the analyses of the related bibliography published in PUBMED database. Normal or minimal obstructive coronary artery disease (CAD) at angiography is a common finding in women with signs of ischaemia. Up to 50% of them will have coronary microvascular dysfunction, suggesting that the mechanism of ischaemia may be localised at coronary microcirculation level. Noninvasive measurements of coronary microvascular function can be performed by radionuclide techniques. In particular, positron emission tomography (PET) measures myocardial blood flow (MBF) not only relatively but also in absolute units. Thus, PET offers the possibility to uncover microvascular dysfunction even in patients without obstructive CAD. PET-derived estimates of MBF showed an abnormal coronary microvascular function in women with chest pain and non-obstructive CAD and in women with high-risk conditions for CAD. Interestingly, there is a relationship between an abnormal coronary vascular function and adverse cardiovascular outcomes. In particular, this significant relationship was observed with measurements related to endothelial function. Recent evidence suggests that vascular dysfunction plays a central role as an estimator of outcomes in women at risk for or with IHD. Therefore, assessment of coronary vascular function in these women appears to be of clinical relevance. Whether such evaluation may have an impact to reduce cardiac events needs further investigation.

    In the clinical practice, the evaluation of myocardial perfusion by using Computed Tomography (CT) Imaging is usually performed visually or semi-quantitatively. The scarcity of quantitative perfusion data not always allows a proper diagnose of patients which are suspected of suffering from some diseases, such as Ischemic Heart Disease (IHD). In this work, a clinical tool for the automatic quantification of myocardial perfusion in patients with suspected IHD is proposed. Myocardial perfusion is assessed based on a combined diagnosis protocol (CT/CTP protocol) which involves the acquisition of two contrastenhanced CT images, one obtained at rest and another acquired under pharmacological stress. The clinical tool allows the automatic quantification of perfusion in different myocardial segments defined according to the 16-AHA-segmentation model of the left ventricle, by providing the mean of Hounsfield Units in those regions. Based on this analysis, the clinicians can compare the values at baseline and at hyperemia, and they can better determine hypoperfusion defects in patients with IHD. The validation of the clinical tool was performed by comparing automatic and manual perfusion measurements of 10 patients with suspected IHD who were previously assessed with Single Photon Emission Computed Tomography (SPECT) for perfusion analysis. A strong linear correlation was found between the automatic and manual results. Afterwards, perfusion defects obtained from CT/CTP protocol were compared to perfusion defects from SPECT, to assess the applicability of this clinical tool for the diagnosis of IHD. (Author)

    2008-01-01

    Starting out from a brief description of the determinants of coronary blood flow (perfusion, pressure, extravascular compression, autoregulation, metabolic regulation, endothelium-mediated regulation and neurohumoral regulation) the present review highlights the overwhelming importance of metabolic regulation such that coronary blood flow is increased at increased heart rate under physiological circumstances and the overwhelming importance of extravascular compression such that coronary blood flow is decreased at increased heart rate through reduction of diastolic duration in the presence of severe coronary stenoses. The review goes on to characterize the role of heart rate in the redistribution of regional myocardial blood flow between a normal coronary vascular tree with preserved autoregulation and a poststenotic vasculature with exhausted coronary reserve. When flow is normalized by heart rate, there is a consistent close relationship of regional myocardial blood flow and contractile function for each single cardiac cycle no matter whether or not there is a coronary stenosis and what the actual blood flow is. β-Blockade improves both flow and function along this relationship. When the heart rate reduction associated with β-blockade is prevented by pacing, α-adrenergic coronary vasoconstriction is unmasked and both flow and function are deteriorated. Selective heart rate reduction, however, improves both flow and function without any residual negative effect such as unmasked α-adrenergic coronary vasoconstriction or negative inotropic action.

    Full Text Available Inflammation is an important factor in the pathogenesis of atherosclerosis, and several markers of inflammation have been associated with an increased risk of cardiovascular events. Physical activity may lower the risk of coronary heart disease(CHD by mitigating inflammation. The aim of the study was to investigate the effects of aerobic exercise training on systemic inflammatory response in patients with stabile coronary artery disease participating in a cardiovascular rehabilitation exercise program. Male (n=29 and female (n=23 patients with stable coronary heart disease were recruited for this study. All patients were divided into two groups: group with regular aerobic physical training during cardiovascular rehabilitation program phase II along 3 weeks in rehabilitation center and 3 weeks after that in home of patients and sedentary lifestyle group. There were no significant differences in gender distribution among analyzed groups. Student’s t test showed no significant difference in mean age, waist circumference (OS and waist/hip ratio (WHR. Degree of obesity was measured by BMI, and there was a significant improvement in BMI in patients who underwent the six-week physical training compared to control group (p<0.05.Physical training during 6 weeks did not show any effects on leukocyte count and ICAM-1 levels compared to control group. The exercise training induced reduction in plasma CRP levels by 23.72%, p<0.001, and reduction in plasma VCAM-1 levels by Moderate aerobic exercise training resulted in a significant reduction of inflammatory state by decreasing CRP and VCAM-1 levels without significant body mass and visceral obesity reduction. The obtained results indicate that regular physical activity is clinically attractive in primary and secondary prevention of coronary heart diseases.

    To evaluate how a comprehensive evidence-based clinical review by a multidisciplinary revascularization heart team on treatment decisions for revascularization in patients with complex coronary artery disease using SYNTAX scores combined with Society of Thoracic Surgeons-derived clinical variables can be additive to the utilization of Appropriate Use Criteria for coronary revascularization. Decision-making regarding the use of revascularization for coronary artery disease has come under major scrutiny due to inappropriate overuse of revascularization. There is little data in routine clinical practice evaluating how a structured, multidisciplinary heart team approach may be used in combination with the Appropriate Use Criteria for revascularization. From May 1, 2012 to January 1, 2015, multidisciplinary revascularization heart team meetings were convened to discuss evidence-based management of 301 patients with complex coronary artery disease. Heart team recommendations were adjudicated with the Appropriate Use Criteria for coronary revascularization for each clinical scenario using the Society for Cardiovascular Angiography and Interventions' Quality Improvement Toolkit (SCAI-QIT) Appropriate Use Criteria App. Concordance of the Heart Team to Appropriate Use Criteria had a 99.3% appropriate primary indication for coronary revascularization. Among patients who underwent percutaneous revascularization, 34.9% had an inappropriate or uncertain indication as recommended by the Heart Team. Patients with uncertain or inappropriate percutaneous coronary interventions had significantly higher SYNTAX score (27.3 ± 6.6; 28.5 ± 5.5; 19.2 ± 6; P coronary artery disease. A formal, multidisciplinary revascularization heart team can provide proper validation for clinical decisions and should be considered in combination with the Appropriate Use Criteria for coronary revascularization to formulate revascularization strategies for individuals in a patient

    Full Text Available Background. Healthcare is a challenging, yet so demanding sector that developing countries are paying more attention to recently. Statistics show that rural areas are expected to develop a high rate of heart diseases, which is a leading cause of sudden mortality, in the future. Thus, providing solutions that can assist rural people in detecting the cardiac risks early will be vital for uncovering and even preventing the long-term complications of cardiac diseases. Methodology. Mobile technology can be effectively utilized to limit the cardiac diseases’ prevalence in rural Middle East. This paper proposes a smart mobile solution for early risk detection of hard coronary heart diseases that uses the Framingham scoring model. Results. Smart HeartCare+ mobile app estimates accurately coronary heart diseases’ risk over 10 years based on clinical and nonclinical data and classifies the patient risk to low, moderate, or high. HeartCare+ also directs the patients to further treatment recommendations. Conclusion. This work attempts to investigate the effectiveness of the mobile technology in the early risk detection of coronary heart diseases. HeartCare+ app intensifies the communication channel between the lab workers and patients residing in rural areas and cardiologists and specialist residing in urban places.

    We present a case of coronary ectasia and LAD coronary artery aneurysm with angiographic characteristics of Kawasaki disease in a three-yr-old girl two-yr status post-orthotopic heart transplant. Coronary anomalies were noted during initial screening coronary angiography two yr after transplant. Subsequent review of the donor echocardiogram revealed that the LMCA had been mildly dilated prior to transplant. In the absence of any symptoms consistent with Kawasaki disease in the transplant recipient, this appears to be a case of Kawasaki disease in the organ donor manifesting with coronary anomalies in the transplant recipient. The patient has done well clinically, and repeat coronary angiography has revealed partial regression of coronary anomalies. Given multiple reports in the literature of persistent abnormalities of coronary artery morphology and function after Kawasaki disease, close monitoring is warranted, with consideration of potential coronary protective medical therapies. © 2012 John Wiley & Sons A/S.

    This study was done in order to evaluate the effect of serum levels of total cholesterol, triglycerides, low-density lipoprotein-cholesterol and high-density lipoprotein-cholesterol on 10-year coronary heart disease risk distribution change. This study included 110 subjects of both genders (71 female and 39 male), aged 29 to 73, treated at the Outpatient Department of Atherosclerosis Prevention, Centre for Laboratory Medicine, Clinical Centre Vojvodina. The 10-year coronary heart disease risk was estimated on first examination and after one-year treatment by means of Framingham, PROCAM and SCORE coronary risk scores and their modifications (Framingham Adult Treatment Panel III, Framingham Weibul, PROCAM NS and PROCAM Cox Hazards). Age, gender, systolic and diastolic blood pressure, smoking, positive family history and left ventricular hypertrophy are risk factors involved in the estimation of coronary heart disease besides lipid parameters. There were no significant differences in nutritional status, smoking habits, systolic and diastolic pressure, and no development of diabetes mellitus or cardiovascular incidents during one-year follow. However, a significant reduction in cholesterol level (p cholesterol (p cholesterol (p coronary heart disease risk (Framingham- p risk category (Framingham- p risk at the beginning of the study. Our results show that the correction of lipid level after one-year treatment leads to a significant redistribution of 10-year coronary heart disease risk estimated by means of seven different coronary risk scores. This should stimulate patients and doctors to persist in prevention measures.

    Unstable atherosclerotic plaque is a dangerous clinical state, possibly leading to acute coronary deficiency resulting in cardiac infarction. Inflammatory factor's role in creating pathological lesions in the endothelium of coronary vessels is frequently raised. This state may be caused by bacteria able to initiate clot formation in blood vessel and destabilizing atherosclerotic plaque already present. Source of these pathogens are chronic inflammatory processes occurring in organism, among them periodontal disease as one of more frequent. Aim of the work was to evaluate incidence of selected anaerobic bacteria in subgingival plaque and in atherosclerotic plaque in patients treated surgically because of coronary vessels' obliteration. Study was performed on 20 individuals with chronic periodontitis. Subgingival plaque was collected from periodontal pockets deeper than 5 mm DNA test was used for marking eight pathogens responsible for periodontal tissues destruction. In the same patients, as well as in 10 edentulous individuals material from atherosclerotic plaque was collected during by-pass implantation procedure, and identical DNA testing occurred. In 13 of 20 patients pathogens most frequent in severe chronic periodontitis were found in coronary vessels. In 10 cases those bacteria were also present in atherosclerotic plaque. Pathogens linked with periodontal disease were also found in 7 of 10 edentulous individuals. Most frequently marked bacteria were: Porphyromonas gingivalis and Treponema denticola. It seems that advancement of periodontal disease does not have influence on bacteria permeability to coronary vessels. Important is the presence of active inflammatory process expressed by significantly higher bleeding index in patients with marked bacteria in atherosclerotic plaque.

    The development of the understanding of the underlying causes of coronary heart disease has undergone several stages. Ecological studies, such as the Seven Countries' Study, showed a possible relationship between mortality in coronary heart disease and intake of saturated fats. The investigated area with the lowest rates of cardiovascular disease was the island of Crete, Greece. A discussion soon started to evolve around the Mediterranean diet, which at the time consisted of mainly foods of vegetable origin, olive oil and cereals of unrefined nature. Several clinical trials have been undertaken since, including the Lyon Heart Diet Study where it was clearly shown that both mortality and morbidity in coronary heart disease was substantially lowered by Mediterranean food compared to controls. Dean Ornish proved that an extreme regimen actually could reduce already existing sclerotic plaques, while the WHI study showed that a more modest diet change diet not cause the intended reduction in heart disease in middle-aged women. Another prospective study of a similar age group of women showed that a diet with a low glycemic load gave a good reduction in coronary heart disease. Multiple studies of different components of food have shown no positive result, pointing at the whole diet rather than its components of nutrients being of importance. Today, the experts agree on the optimal diet to prevent not only heart disease but also cancer forms and other chronic disease such as type 2 diabetes mellitus. This diet is consisting of a lot of fruit and vegetables, lots of fish, less salt and sugar, more unrefined cereals, beans and nuts. Going from a general notion of Mediterranean food to testing that food in clinical settings and testing nutrients as preventative agents, we can conclude that a generally healthy lifestyle, including a healthy diet, appropriate amounts of physical activity, good sleep and less stress, is the way to a heart healthy life.

    An improved method for detecting coronary heart disease (CHD) could have substantial clinical impact. Building on the idea that systemic effects of CHD risk factors are a conglomeration of genetic and environmental factors, we use machine learning techniques and integrate genetic, epigenetic and phenotype data from the Framingham Heart Study to build and test a Random Forest classification model for symptomatic CHD. Our classifier was trained on n = 1,545 individuals and consisted of four DNA methylation sites, two SNPs, age and gender. The methylation sites and SNPs were selected during the training phase. The final trained model was then tested on n = 142 individuals. The test data comprised of individuals removed based on relatedness to those in the training dataset. This integrated classifier was capable of classifying symptomatic CHD status of those in the test set with an accuracy, sensitivity and specificity of 78%, 0.75 and 0.80, respectively. In contrast, a model using only conventional CHD risk factors as predictors had an accuracy and sensitivity of only 65% and 0.42, respectively, but with a specificity of 0.89 in the test set. Regression analyses of the methylation signatures illustrate our ability to map these signatures to known risk factors in CHD pathogenesis. These results demonstrate the capability of an integrated approach to effectively model symptomatic CHD status. These results also suggest that future studies of biomaterial collected from longitudinally informative cohorts that are specifically characterized for cardiac disease at follow-up could lead to the introduction of sensitive, readily employable integrated genetic-epigenetic algorithms for predicting onset of future symptomatic CHD.

    The aims of the study were to evaluate the prevalence of acute coronary syndrome (ACS) among patients presenting with atypical chest pain who are evaluated for acute aortic syndrome (AAS) or pulmonary embolism (PE) with computed tomoangiography (CTA) and discuss the rationale for the use of triple rule-out (TRO) protocol for triaging these patients. This study is a retrospective analysis of patients presenting with atypical chest pain and evaluated with thoracic (CTA), for suspicion of AAS/PE. Two physicians reviewed patient files for demographic characteristics, initial CT and final clinical diagnosis. Patients were classified according to CTA finding into AAS, PE and other diagnoses and according to final clinical diagnosis into AAS, PE, ACS and other diagnoses. Four hundred and sixty-seven patients were evaluated: 396 (84.8%) patients for clinical suspicion of PE and 71 (15.2%) patients for suspicion of AAS. The prevalence of ACS and AAS was low among the PE patients: 5.5% and 0.5% respectively (P = 0.0001), while the prevalence of ACS and PE was 18.3% and 5.6% among AAS patients (P = 0.14 and P = 0.34 respectively). The prevalence of ACS and AAS among patients suspected clinically of having PE is limited while the prevalence of ACS and PE among patients suspected clinically of having AAS is significant. Accordingly patients suspected for PE could be evaluated with dedicated PE CTA while those suspected for AAS should still be triaged using TRO protocol.

  20. Coronary hemodynamic responses during local hemodilution in canine hearts

    To evaluate the effect of hemodilution per se on coronary hemodynamics, experiments were performed in 36 anesthetized, open-chest dogs whose left anterior descending coronary artery (LAD) was perfused selectively with either normal arterial blood or arterial blood diluted with lactated Ringer solution. LAD blood flow (CBF) was measured with an electromagnetic flowmeter and its transmural distribution assessed with 15-{mu}m radioactive microspheres. With perfusion pressure normal, graded hemodilution caused progressive, transmurally uniform increases in CBF that showed an nonlinear relationship to inflow hematocrit. Increased peak reactive hyperemic flow and decreased dilator reserve ratio indicated that both reduced viscosity and vasodilation contributed to increased CBF during hemodilution. Hypotension alone reduced CBF, with greater effect in the subendocardium. Additional hemodilution returned CBF to normotensive value, but relative subendocardial hypoperfusion persisted. The present study provides fundamental information on effects of hemodilution on coronary hemodynamics without the systemic responses that complicated previous studies utilizing whole body exchange transfusions.

    Cardiac rehabilitation (CR) is a complex multifaceted intervention consisting of three core modalities: education, exercise training and psychological support. Whilst exercise and psychological interventions for patients with coronary heart disease (CHD) have been the subject of Cochrane systematic reviews, the specific impact of the educational component of CR has not previously been investigated. 1. Assess effects of patient education on mortality, morbidity, health-related quality of life (HRQofL) and healthcare costs in patients with CHD.2. Explore study level predictors of the effects of patient education (e.g. individual versus group intervention, timing with respect to index cardiac event). The following databases were searched: The Cochrane Library, (CENTRAL, CDSR, DARE, HTA, NHSEED), MEDLINE (OVID), EMBASE (OVID), PsycINFO (EBSCOhost) and CINAHL (EBSCOhost). Previous systematic reviews and reference lists of included studies were also searched. No language restrictions were applied. 1. Randomised controlled trials (RCTs) where the primary interventional intent was education.2. Studies with a minimum of six-months follow-up and published in 1990 or later.3. Adults with diagnosis of CHD. Two review authors selected studies and extracted data. Attempts were made to contact all study authors to obtain relevant information not available in the published manuscript. For dichotomous variables, risk ratios and 95% confidence intervals (CI) were derived for each outcome. For continuous variables, mean differences and 95% CI were calculated for each outcome. Thirteen RCTs involving 68,556 subjects with CHD and follow-up from six to 60 months were found. Overall, methodological quality of included studies was moderate to good. Educational 'dose' ranged from a total of two clinic visits to a four-week residential stay with 11 months of follow-up sessions. Control groups typically received usual medical care. There was no strong evidence of an effect of education on

  2. Coated stents to prevent restenosis in coronary heart disease

    Directory of Open Access Journals (Sweden)

    2005-11-01

    Full Text Available Background: In-stent-restenosis (ISR is considered to be an essential limiting factor of stenting in coronary heart disease (CHD. The development of coated stents has raised expectations on substantial lowering restenosis after stenting with decreasing the rate of restenosis and a reduction in the rate of clinical events. Objectives: The present analysis addresses the questions on medical effectiveness and cost-effectiveness of the use of various coated stent types in CHD. Methods: The literature was searched in December 2004 in the most relevant medical and economic databases. The medical evaluation was conducted on the basis of published RCT. The data from the studies regarding various angiographic, sonographic and clinical endpoints were checked for methodical quality and summarised in meta-analyses. Within the scope of economic evaluation the primary studies were analysed and modelling was performed, applying clinical effect estimates from the meta-analyses of the medical evaluation and current estimates of German costs. Results: Medical evaluation: Ten different stenttypes were used in the included 26 RCT. The results for heparin, silicon-carbide, carbon and PTFE coated stenttypes could not reveal any significant differences between the medical effectiveness of coated and uncoated stents. The application of sirolimus, paclitaxel, everolimus and 7-hexanoyltaxol eluting stents showed a significant lower restenosis at 6-9 months with decrease in the rate of restenosis for polymer-based sirolimus, paclitaxel and 7-hexanoyltaxol eluting stents. In contrast, the use of gold-coated and actinomycin-D eluting stents was associated with a significantly higher restenosis. The polymer-based sirolimus and paclitaxel eluting stents also showed a significant and considerable reduction in the rate of repeated percutaneous revascularisations at 6-12 months (3.5% vs. 19.7%; p<0.0001, RR=0.19 [95%CI: 0.11; 0.33] and 3.5% vs. 12.2%; p<0.0001, RR=0.30 [95%CI: 0

    Diet is a key modifiable risk factor in the prevention and risk reduction of coronary heart disease (CHD). Results from the Seven Countries Study in the early 1970s spurred an interest in the role of single nutrients such as total fat in CHD risk. With accumulating evidence, we have moved away from a focus on total fat to the importance of considering the quality of fat. Recent meta-analyses of intervention studies confirm the beneficial effects of replacing saturated fat with polyunsaturated fatty acids on CHD risk. Scientific evidence for a detrimental role of trans fat intake from industrial sources on CHD risk has led to important policy changes including listing trans fatty acid content on the "Nutrition Facts" panel and banning the use of trans fatty acids in food service establishments in some cities. The effects of such policy changes on changes in CHD incidence are yet to be evaluated. There has been a surging interest in the protective effects of vitamin D in primary prevention. Yet, its associations with secondary events have been mixed and intervention studies are needed to clarify its role in CHD prevention. Epidemiological and clinical trial evidence surrounding the benefit of B vitamins and antioxidants such as carotenoids, vitamin E, and vitamin C, have been contradictory. While pharmacological supplementation of these vitamins in populations with existing CHD has been ineffective and, in some cases, even detrimental, data repeatedly show that consumption of a healthy dietary pattern has considerable cardioprotective effects for primary prevention. Results from these studies and the general ineffectiveness of nutrient-based interventions have shifted interest to the role of foods in CHD risk reduction. The strongest and most consistent protective associations are seen with fruit and vegetables, fish, and whole grains. Epidemiological and clinical trial data also show risk reduction with moderate alcohol consumption. In the past decade, there has

    Obesity, hypertension, and coronary artery disease are prevalent in the general population and well recognized as contributors to cardiac morbidity and mortality. With surgical and medical advances, there is a growing and aging population with congenital heart disease who are also at risk of developing these comorbidities. In addition, some congenital cardiac lesions predispose patients to conditions such as hypertension or coronary artery disease. The effect of these comorbidities on the structurally abnormal heart is not well understood, but might be very important, especially in those with residual abnormalities. Thus, in addition to surveillance for and treatment of late complications it is important for the congenital cardiologist to consider and aggressively manage acquired comorbidities. In this review we explore the prevalence of hypertension, obesity, and coronary artery disease, discuss congenital lesions that predispose to these conditions and review management strategies for this unique population.

    2017-04-01

    Traditional approaches for risk assessment of ischemic heart disease (IHD) are based on the physiological consequences of an epicardial coronary stenosis. Of note, normal coronary arteries or nonobstructive coronary artery disease (CAD) is a common finding in women with signs and symptoms of ischemia. Therefore, assessment of risk based on a coronary stenosis approach may fail in women. Positron emission tomography (PET) quantifies absolute myocardial blood flow (MBF) which may help to elucidate other mechanisms involved such as endothelial dysfunction and alterations in the smooth muscle cell relaxation responsible for IHD in women. The objective of the present review is to describe the current state of the art of PET imaging in assessing IHD in women with nonobstructive CAD.

    2007-01-01

    BACKGROUND: Studies have shown a positive association between trans fatty acids (TFA) intake and risk of coronary heart disease (CHD), primarily accounted for by industrially produced TFA. Some of these studies indicate an inverse association between ruminant TFA (R-TFA) intake and CHD implying...

    The prognostic significance of prior heart failure in acute coronary syndromes has not been well studied. Accordingly, we evaluated the baseline characteristics, management patterns and clinical outcomes in patients with acute coronary syndromes who had prior heart failure. The study population consisted of acute coronary syndrome patients in the Global Registry of Acute Coronary Events, expanded Global Registry of Acute Coronary Events and Canadian Registry of Acute Coronary Events between 1999 and 2008. Of the 13,937 eligible patients (mean age 66±13 years, 33% female and 28.3% with ST-elevation myocardial infarction), 1498 (10.7%) patients had a history of heart failure. Those with prior heart failure tended to be older, female and had lower systolic blood pressure, higher Killip class and creatinine on presentation. Prior heart failure was also associated with significantly worse left ventricular systolic function and lower rates of cardiac catheterization and coronary revascularization. The group with previous heart failure had significantly higher rates of acute decompensated heart failure, cardiogenic shock, myocardial (re)infarction and mortality in hospital. In multivariable analysis, prior heart failure remained an independent predictor of in-hospital mortality (odds ratio 1.48, 95% confidence interval 1.08-2.03, p=0.015). Prior heart failure was associated with high risk features on presentation and adverse outcomes including higher adjusted in-hospital mortality in acute coronary syndrome patients. However, acute coronary syndrome patients with prior heart failure were less likely to receive evidence-based therapies, suggesting potential opportunities to target more intensive treatment to improve their outcome. © The European Society of Cardiology 2015.

  18. Radiologic evaluation of coronary artery disease in adults with congenital heart disease.

    Valenzuela, David M; Ordovas, Karen G

    2016-01-01

    Improved surgical and medical therapy have prolonged survival in patients with congenital heart disease (CHD) such that general medical conditions like coronary artery disease (CAD) are now the main determinants of mortality. A summary of the association of CAD with CHD, as well as a discussion of the radiologic evaluation of the coronary arteries in adults with CHD is described herein. Cross sectional imaging to evaluate CAD in adults with CHD should follow the same appropriateness criteria as gender and aged matched patients without CHD. Coronary CT imaging may be particularly valuable in evaluating the coronary arteries in this patient population as invasive coronary angiography may prove challenging secondary to complicated or unconventional anatomy of the coronary arteries. Further, typical methods for evaluating CAD such as stress or echocardiography may be impractical in adults with CHD. Finally, delineating the anatomic relationship of the coronary arteries and their relationship with the sternum, chest wall, conduits, grafts, and valves is highly recommended in patients with CHD prior to reintervention to avoid iatrogenic complications.

  19. Impact of Experiencing Acute Coronary Syndrome Prior to Open Heart Surgery on Psychiatric Status

    Full Text Available Abstract Objective: The incidence of depression and anxiety is higher in patients with acute coronary syndrome. The aim of this study is to determine whether experiencing acute coronary syndrome prior to open heart surgery affects patients in terms of depression, hopelessness, anxiety, fear of death and quality of life. Methods: The study included 63 patients who underwent coronary bypass surgery between January 2015 and January 2016. The patients were divided into two groups: those diagnosed after acute coronary syndrome (Group 1 and those diagnosed without acute coronary syndrome (Group 2. Beck depression scale, Beck hopelessness scale, Templer death anxiety scale and death depression scale, State-Trait anxiety inventory and WHOQOL-Bref quality of life scale were applied. Results: There was no significant difference between the two groups in terms of the total score obtained from Beck depression scale, Beck hopelessness scale - future-related emotions, loss of motivation, future-related expectations subgroups, death anxiety scale, the death depression scale, State-Trait Anxiety Inventory - social and environmental subgroups. The mental quality of life sub-scores of group 2 were significantly higher. The patients in both groups were found to be depressed and hopeless about the future. Anxiety levels were found to be significantly higher in all of the patients in both groups. Conclusion: Acute coronary syndrome before coronary artery bypass surgery impairs more the quality of life in mental terms. But unexpectedly there are no differences in terms of depression, hopelessness, anxiety and fear of death.

    Alopecia has been associated with an increased risk of coronary heart disease as well as the following risk factors for cardiovascular disease: hyperinsulinaemia, insulin resistance, metabolic syndrome, dyslipidaemia, and hypertension. We performed a meta-analysis to quantitatively determine the level of risk of coronary heart disease and risk factors in individuals with alopecia. A systematic literature search was conducted using several databases. We calculated pooled odds ratios and 95% confidence intervals using a random effects model. In total, 31 studies comprising 29,254 participants with alopecia were eligible for the meta-analysis and showed that alopecia is associated with an increased risk of coronary heart disease (OR 1.22, 95% CI: 1.07-1.39), hyperinsulinaemia (OR 1.97, 95% CI: 1.20-3.21), insulin resistance (OR 4.88, 95% CI: 2.05-11.64), and metabolic syndrome (OR 4.49, 95% CI: 2.36-8.53). Individuals with alopecia were also shown to be more likely compared to those without alopecia to have higher serum cholesterol levels (OR 1.60, 95% CI: 1.17-2.21), higher serum triglyceride levels (OR 2.07, 95% CI: 1.32-3.25), higher systolic blood pressures (OR 1.73, 95% CI: 1.29-2.33), and higher diastolic blood pressures (OR 1.59, 95% CI: 1.16-2.18). Alopecia is associated with an increased risk of coronary heart disease, and there appears to be a dose-response relationship with degree of baldness whereby the greater the severity of alopecia, the greater the risk of coronary heart disease. Alopecia is also associated with an increased risk of hypertension, hyperinsulinaemia, insulin resistance, metabolic syndrome, and having elevated serum total cholesterol and triglyceride levels.

    To investigate the difference of serum estrogen, serum lipids and inflammatory factors levels in postmenopausal women with coronary heart blood stasis syndrome and non-blood stasis syndrome. Twenty five healthy postmenopausal women were selected as a healthy control group who were compared with 43 postmenopausal women with coronary heart disease (CHD) first visiting a doctor for the CHD. Among the postmenopausal women with CHD, There were 23 patients with blood stasis syndrome (BSS) and 20 patients with non-blood stasis syndrome (NBSS). The levels of plasma triglyceride (TG), total cholesterol (TC) were determined in blood samples taken after patients' admission in Beijing Anzhen Hospital. The serum estradiol(E2) was measured by electrochemiluminescence assay and soluble intercellular adhesion molecule-1(sICAM-1) was measured by enzyme-linked immune sorbent assay (ELISA). Compared with the healthy control group, the levels of TG and TC, sICAM-1 in coronary heart disease group were all significantly increased (P0.05), and there was an increasing trend of serum sICAM-1 levels (P>0.05). There were negative significant correlations between serum E2 levels and TC, sICAM-1 levels in patient with coronary heart disease. The estrogen level of menopausal women with coronary heart disease is lower than healthy menopausal women. With the low estrogen levels, postmenopausal women tend to have high levels of blood lipids and sICAM-1, which elucidates that the estrogen could regulate lipids and attenuate inflammatory response to play a protective role on blood vessels.

    Ruptured sinus of Valsalva aneurysm is an unusual cause for congestive heart failure, and anomalous coronary arteries have rarely been found in association. A 47-year-old man developed sudden onset heart failure due to a ruptured noncoronary sinus of Valsalva fistula to the right atrium. Coronary angiography revealed an anomalous left coronary artery arising from the right coronary sinus, limiting percutaneous options for repair. We review the incidence, complications, and management of sinus of Valsalva aneurysms and anomalous left coronary arteries.

    To evaluate the association between periodontal disease, tooth loss and coronary heart disease (CHD). There is still controversy about the relationship between periodontal disease and tooth loss with vessel obstruction assessed using coronary angiography. This cross-sectional study included 195 patients that underwent coronary angiography and presented with at least six teeth. Patients were classified into three categories of coronary obstruction severity: absence; one or more vessels with ≤ 50% obstruction; and one or more vessels with ≥ 50% obstruction. The extent of coronary obstruction was dichotomized into 0 and ≥ 1 affected vessels. A periodontist blinded to patient CHD status conducted a full mouth examination to determine mean clinical attachment loss, mean periodontal probing depth and tooth loss. Multiple logistic regression models were applied adjusting for age, gender, hypertension, smoking, body mass index, low-density lipoprotein cholesterol and C-reactive protein. Most patients were males (62.1%) older than 60 years (50.8%), and 61% of them had CHD. Mean periodontal probing depth, clinical attachment loss and tooth loss were 2.64 ± 0.72 mm, 4.40 ± 1.31 mm and 12.50 ± 6.98 teeth respectively. In the multivariable models, tooth loss was significantly associated with a higher chance of having at least one obstructed vessel (odds ratio = 1.04; 95% confidence interval 1.01-1.09) and with vessel obstruction ≥ 50% (odds ratio = 1.06; 95% confidence interval 1.01-1.11). No significant associations were found between periodontal variables and vessel obstruction. Tooth loss was found to be a risk indicator for CHD. © 2015 John Wiley & Sons A/S.

    Atherosclerosis is a multifactor disease, in which dysfunction of the endothelium leads to the emergence of its adhesion molecules. to investigate the expression of the endothelial adhesion molecules PECAM (CD31), ICAM, and VCAM, as well as adherent endothelial T cells and monocytes. The material examined was en face pulmonary and coronary artery samples taken during autopsies (10 men), and en face specimens obtained from the coronary artery fragments taken from coronary heart disease patients during endarterectomy (37 men). This investigation used antibodies to the adhesion molecules ICAM-1, VCAM-1, and PECAM and those to CD3, CD4, CD8 T-cells and CD68 monocytes. The endothelial cells in the atherosclerotically intact coronary arteries had an elongated shape and were aligned along the blood flow. Those located above atheromas and fibroatheromas changed their shape from elongated to polygonal. Above the fatty streaks and atheromas, the reaction with antibodies to CD31 antigens became weaker at the edge of endothelial cells and disappeared in places. While the atherosclerotic process progressed, the reaction with the CD31 antigen at the edge of endothelial cells was similar in intensity to that on the surface of the endothelium. Adhesion of T cells and monocytes to the endothelium of coronary arteries increased as the atherosclerotic vascular process progressed. T cells and monocytes more often adhered to the endothelium at the sites where the endothelial cells contacted each other. Heterogeneity was found in the endothelial cells: their shape, the expression of adhesion molecules, and the adhesion of lymphocytes and monocytes to them changed during the progression of the atherosclerotic process.

    Full Text Available Abstract Background The determination of coronary flow reserve (CFR is an essential concept at the moment of decision-making in ischemic heart disease. There are several direct and indirect tests to evaluate this parameter. In this sense, dobutamine stress echocardiography is one of the pharmacological method most commonly used worldwide. It has been previously demonstrated that CFR can be determined by this technique. Despite our wide experience with dobutamine stress echocardiography, we ignored the necessary heart rate to consider sufficient the test for the analysis of CFR. For this reason, our main goal was to determine the velocity of coronary flow in each stage of dobutamine stress echocardiography and the heart rate value necessary to double the baseline values of coronary flow velocity in the territory of the left anterior descending (LAD coronary artery. Methods A total of 33 consecutive patients were analyzed. The patients included had low risk for coronary artery disease. All the participants underwent dobutamine stress echocardiography and coronary artery flow velocity was evaluated in the distal segment of LAD coronary artery using transthoracic color-Doppler echocardiography. Results The feasibility of determining CFR in the territory of the LAD during dobutamine stress echocardiography was high: 31/33 patients (94%. Mean CFR was 2.67 at de end of dobutamine test. There was an excellent concordance between delta HR (difference between baseline HR and maximum HR and the increase in the CFR (correlation coefficient 0.84. In this sense, we found that when HR increased by 50 beats, CFR was ≥ 2 (CI 93-99.2%. In addition, 96.4% of patients reached a CFR ≥ 2 (IC 91.1 - 99% at 75% of their predicted maximum heart rate. Conclusions We found that the feasibility of dobutamine stress echocardiography to determine CFR in the territory of the LAD coronary artery was high. In this study, it was necessary to achieve a difference of 50 bpm

    To assess the characteristics and determinants of heart rate turbulence (HRT) in individuals without any apparent heart disease and in patients with coronary artery disease (CAD). Heart rate turbulence parameters, turbulence onset (TO), and turbulence slope (TS) were calculated on 24 h electrocardiogram recordings in 209 individuals without any heart disease (group 1) and in 157 CAD patients (group 2). In group 1, only age independently predicted abnormal TO (≥0%) [odds ratio (OR), 1.05; PCoronary artery disease group, however, did not predict abnormal HRT parameters in multivariable analyses, both in the whole population and when comparing two subgroups matched for age and gender. Age and (for TS) LVEF, indeed, were the only independent predictors of abnormal HRT. Age is a major HRT determinant both in subjects without any apparent heart disease and in stable CAD patients. Hypertension and LVEF contribute independently to HRT in these two groups, respectively. Coronary artery disease group was not by itself associated with abnormal HRT parameters in multivariable analyses. Published on behalf of the European Society of Cardiology.

    Risk stratification in patients with stable ischemic heart disease is essential to guide treatment decisions. In this regard, whether coronary anatomy, physiology, or plaque morphology is the best determinant of prognosis (and driver an effective therapeutic risk reduction) remains one of the greatest ongoing debates in cardiology. In the present report, we review the evidence for each of these characteristics and explore potential algorithms that may enable a practical diagnostic and therapeutic strategy for the management of patients with stable ischemic heart disease. © 2016 American Heart Association, Inc.

    The role of periodontal disease remains a headline-generating topic. Periodontal disease, caused chiefly by bacteria, is characterized by inflammation, bacteremia, a strong immune response, and loss of connective tissue attachment and bone. It is speculated that a continuous long-term exposure to oral bacteremia and bacterial toxins induces immune responses that could contribute to coronary atherosclerosis and, in conjunction with other risk factors, lead to coronary heart disease and myocardial infarction. Periodontal disease might initiate pathological changes in blood vessel walls and act as a precursor of atherosclerosis in susceptible hosts. Many causal factors can play a role in heart diseases. Periodontal disease caused by pathogen bacteria as a low-grade inflammation could represent one of several possible causal factors of heart disease.

    To assess the diagnostic performance of respiratory self-navigation for whole-heart coronary magnetic resonance (MR) angiography in a patient cohort referred for diagnostic cardiac MR imaging. Written informed consent was obtained from all participants for this institutional review board-approved study. Self-navigated coronary MR angiography was performed after administration of a contrast agent in 78 patients (mean age, 48.5 years ± 20.7 [standard deviation]; 53 male patients) referred for cardiac MR imaging because of coronary artery disease (n = 40), cardiomyopathy (n = 14), congenital anomaly (n = 17), or "other" (n = 7). Examination duration was recorded, and the image quality for each coronary segment was assessed with consensus reading. Vessel sharpness, length, and diameter were measured. Quantitative values in proximal, middle, and distal segments were compared by using analysis of variance and t tests. A double-blinded comparison with the results of x-ray angiography was performed when such results were available. When patients with different indications for cardiac MR imaging were examined with self-navigated postcontrast coronary MR angiography, whole-heart data sets with 1.15-mm isotropic spatial resolution were acquired in an average of 7.38 minutes ± 1.85. The main and proximal coronary segments could be visualized in 92.3% of cases, while the middle and distal segments could be visualized in 84.0% and 55.8% of cases, respectively. Subjective scores and vessel sharpness were significantly higher in the proximal segments than in the middle and distal segments (P < .05). Anomalies of the coronary arteries could be confirmed or excluded in all cases. Per-vessel sensitivity and specificity for stenosis detection were 64.7% and 85.0%, respectively, in the 31 patients for whom reference standard x-ray coronary angiography results were available. The self-navigated coronary MR angiography sequence shows promise for coronary imaging. However, technical

    The National Service Framework for Heart Disease sets national standards and defines service models for coronary heart disease (CHD). Little is known about the impact of this intervention on age inequalities. To determine the changes in the uptake of coronary prevention measures before and after the first year of implementation of the National Service Framework for Coronary Heart Disease, and to compare these changes in uptake of coronary prevention in patients aged 75 years and over with younger patients. Repeated cross-sectional survey using routinely collected data. Seventeen general practices in 17 primary care groups in the Trent Region. All registered patients at baseline and follow-up aged >/=35 years were categorised into three groups: those with either coronary heart disease or a history of stroke; those with diabetes or hypertension who were not in in the first group; and the remaining population. Data from electronic records was collected to show differences in the proportions of patients with coronary risk factors recorded in the previous year. Data was also collected about differences in the proportions of patients with adequate disease control measures. Improvements were demonstrated in the recording of coronary risk factors and of disease control measures. However, compared with patients aged National Service Framework for Coronary Heart Disease. However, there needs to be an effort to strengthen the focus on the care of older patients.

    This study determined the correlations of CXC ligand 16 (CXCL16) and tumor necrosis factor-α (TNF-α) levels with coronary atherosclerotic heart disease (CAHD) and screened for new clinical markers for the prognosis and treatment of the disease. Eighty patients with coronary heart disease and 50 healthy subjects were enrolled into a CAHD or healthy control group, respectively. Computed tomography (CT) coronary angiography and Gensini integral were used to classify plaques and evaluate patients with coronary heart disease. The serum levels of CXCL16 and TNF-α of subjects in each group were detected by enzyme-linked immunosorbent assays (ELISA), and the correlation between levels and clinical markers (such as blood pressure, glucose, lipid and heart rate) and the severity of disease were analyzed. Our results showed the serum levels of CXCL16 and TNF-α were significantly higher in the CAHD group than those in the CK group. The serum CXCL16 levels of the CAHD group patients with plaques were distinctly higher than those of the CADH group patients without plaques, but there were no significant difference in serum TNF-α levels between these two groups of patients. The level of CXCL16 had a significantly positive correlation with the severity of disease, but there was no significant correlation between TNF-α level and the severity of disease. Also, there was no significant correlation between the CXCL16 levels and blood pressure, blood glucose, heart rate, total cholesterol, triglyceride or high-density lipoprotein cholesterol, but there was a clear correlation with the low-density lipoprotein cholesterol. Finally no significant correlations were found between TNF-α levels and each of the clinical markers studied. Based on our findings, the levels of CXCL16 and TNF-α in the patients with coronary heart disease were abnormally increased and the level of CXCL16 correlated closely with the severity of disease. These markers seem to be reliable biological markers for

    In patients with suspected acute coronary syndrome, a new or presumably new left bundle branch block (LBBB) does not always imply ST-segment elevation myocardial infarction (STEMI). We aimed to show the low frequency of STEMI-equivalent in this population and determine the diagnostic value of electrocardiographic and echocardiographic features. From the 387 patients captured by the Louisiana State University code STEMI registry between 2009 and 2012, we examined data on 26 patients with LBBB. These patients were divided into 3 groups according to the final diagnosis: (1) STEMI-equivalent, defined as an acute coronary occlusion on angiography (2 patients), (2) non-ST-segment elevation myocardial infarction (4 patients), and (3) diagnoses other than myocardial infarction (non-MI) (20 patients). Troponin elevation and left ventricular systolic dysfunction were common in all 3 groups (non-significant p-values). Compared with non-MI patients, patients with STEMI-equivalent had a larger degree of ST-segment discordance and T-wave discordance, as assessed by ST/QRS and T/QRS ratios (p<0.001). ST/QRS ratio ≥ 0.2 and T/QRS ratio ≥ 0.5 were sensitive and specific for the diagnosis of STEMI-equivalent in the setting of LBBB. Conversely, absolute values of ST-segment and T-wave discordance were not significantly different between groups. ST-segment concordance was highly specific for the diagnosis of STEMI-equivalent, but had a limited sensitivity. Only a minority of patients with suspected acute coronary syndrome and LBBB have a STEMI-equivalent. Excessive relative discordance of the ST segment or the T wave appears predictive of STEMI-equivalent, but this is only hypothesis-generating considering the small population size.

    Since the introduction of off-pump coronary artery bypass grafting (OPCAB) for coronary multivessel disease there was growing interest to evaluate the impact of OPCAB surgery compared to conventional coronary artery bypass grafting (CCAB) with cardiopulmonary bypass and cardioplegic arrest. However, subsequent prospective randomized studies and meta-analyses comparing OPCAB and CCAB surgery were performed on low-risk patients or mixed-risk populations. They usually failed to demonstrate a significant benefit of OPCAB surgery on early mortality or perioperative major cardiac and cerebrovascular events. In recent years, efforts were made to analyze the meaning of beating-heart concepts for patients with specific cardiac and extracardiac risks like ischemic cardiomyopathy, older age, renal failure, acute coronary syndrome, left main stenosis and others. For these subsets of patients several mono- and multicenter studies are available today. Even if most of them were nonrandomized and thus failed to reach evidence level A according to the AHA/ACC (American Heart Association/American College of Cardiology) definition, they still allow analyzing interim results for each specific perioperative risk factor. Particularly multi-risk patients and patients with severely reduced left ventricular function seem to benefit in terms of perioperative mortality and major morbidity by avoiding cardiopulmonary bypass and cardioplegic arrest. Analyzing early results and long-term follow-up of 364 patients with severely reduced ejection fractioncardiac ischemia and maintaining native coronary blood flow. Follow-up results were comparable for these patients. In conclusion, beating-heart coronary artery bypass grafting seems to be advantageous in various risk populations and should be considered for patients with more than average risks for cardiopulmonary bypass and cardioplegic arrest.

    Full Text Available We determined the association of vitamin D deficiency and the FokI polymorphism of the vitamin D receptor (VDR gene in 760 patients who underwent angiography due to suspected coronary artery disease (CAD. Angiography and the Rentrop scoring system were used to classify the severity of CAD in each patient and to grade the extent of collateral development, respectively. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP was used to determine the FokI VDR gene polymorphism. The prevalence of severe vitamin D deficiency (serum 25(OHD < 10 ng/mL was significantly higher in patients with at least one stenotic coronary artery compared to those without any stenotic coronary arteries. Severe vitamin D deficiency was not independently associated with collateralization, but it was significantly associated with the VDR genotypes. In turn, VDR genotype was independently associated with the degree of collateralization; the Rentrop scores were the highest in FF, intermediate in Ff, and the lowest in the ff genotype. The results show that FokI polymorphism is independently associated with collateralization. Additionally, vitamin D deficiency is more prevalent in patients with CAD that may result from FokI polymorphism. Therefore, maintaining a normal vitamin D status should be a high priority for patients with CAD.

    In a meta-analysis of 37 studies, the effects of psychoeducational (health education and stress management) programs for coronary heart disease patients were examined. The results suggest that these programs yielded a 34% reduction in cardiac mortality; a 29% reduction in recurrence of myocardial infarction (MI); and significant (p psychoeducational programs were found in regard to coronary bypass surgery, anxiety, or depression. The results also suggest that cardiac rehabilitation programs that were successful on proximal targets (systolic blood pressure, smoking behavior, physical exercise, emotional distress) were more effective on distal targets (cardiac mortality and MI recurrences) than programs without success on proximal targets.

    Heart rate (HR) is a risk factor in patients with chronic systolic heart failure (HF) that, when reduced, provides outcome benefits. It is also a target for angina pectoris prevention and a risk marker in chronic coronary artery disease without HF. HR can be reduced by drugs; however, among those used clinically, only ivabradine reduces HR directly in the sinoatrial nodal cells without other known effects on the cardiovascular system. This review provides current information regarding the safety and efficacy of HR reduction with ivabradine in clinical studies involving >36,000 patients with chronic stable coronary artery disease and >6,500 patients with systolic HF. The largest trials, Morbidity-Mortality Evaluation of the I f Inhibitor Ivabradine in Patients With Coronary Disease and Left Ventricular Dysfunction and Study Assessing the Morbidity-Mortality Benefits of the I f Inhibitor Ivabradine in Patients With Coronary Artery Disease, showed no effect on outcomes. The Systolic Heart Failure Treatment With the I f Inhibitor Ivabradine Trial, a randomized controlled trial in >6,500 patients with HF, revealed marked and significant HR-mediated reduction in cardiovascular mortality or HF hospitalizations while improving quality of life and left ventricular mechanical function after treatment with ivabradine. The adverse effects of ivabradine predominantly included bradycardia and atrial fibrillation (both uncommon) and ocular flashing scotomata (phosphenes) but otherwise were similar to placebo. In conclusion, ivabradine improves outcomes in patients with systolic HF; rates of overall adverse events are similar to placebo. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available An association between depression and coronary heart disease is now accepted but there has been little primary care research on this topic. The UPBEAT-UK studies are centred on a cohort of primary patients with coronary heart disease assessed every six months for up to four years. The aim of this research was to determine the prevalence and associations of depression in this cohort at baseline.Participants with coronary heart disease were recruited from general practice registers and assessed for cardiac symptoms, depression, quality of life and social problems.803 people participated. 42% had a documented history of myocardial infarction, 54% a diagnosis of ischaemic heart disease or angina. 44% still experienced chest pain. 7% had an ICD-10 defined depressive disorder. Factors independently associated with this diagnosis were problems living alone (OR 5.49, 95% CI 2.11-13.30, problems carrying out usual activities (OR 3.71, 95% CI 1.93-7.14, experiencing chest pain (OR 3.27, 95% CI 1.58-6.76, other pains or discomfort (OR 3.39, 95% CI 1.42-8.10, younger age (OR 0.95 per year 95% CI 0.92-0.98.Problems living alone, chest pain and disability are important predictors of depression in this population.

    Full Text Available Background: evidence provided by the Framingham Heart Study established the critical role of risk factors in the development of coronary heart disease. Over half a century later, current detection and control are still inadequate. Objective: to identify modifiable risk factors of coronary heart disease in individuals aged 20 to 49 years. Methods: a descriptive, cross-sectional study was conducted in 276 individuals from the doctor’s office No. 1 of the Fabio di Celmo Community Teaching Polyclinic in Cienfuegos. Patients were examined in the clinic visit and/or whole family visit. The studied variables included age, sex, skin color, risk factors (excess weight/obesity, physical inactivity, smoking, hypertension, diabetes, dyslipidemia and psychosocial factors, which were obtained from the medical interview, physical examination, laboratory tests (total cholesterol and triglycerides and review of individual medical records and family history. Results: risk factors most frequently identified were excess weight/obesity (42.4 %, physical inactivity (34.4 % and smoking (20.3 %. Presence of these risk factors increased with age, showing differences in the distribution by sex and was associated with psychosocial factors. Their coexistence and progress with age was significant. Conclusion: prevalence of modifiable risk factors for coronary heart disease in a young population was high, with frequent association, predominating factors related to unhealthy lifestyles.

    To compare two coronary vein imaging techniques using whole-heart balanced steady-state free precession (SSFP) and a targeted double-oblique spoiled gradient-echo (GRE) sequences in combination with magnetization transfer (MT) preparation sequence for tissue contrast improvement. Nine healthy subjects were imaged with the proposed technique. The results are compared with optimized targeted MT prepared GRE acquisitions. Both quantitative and qualitative analyses were performed to evaluate each imaging method. Whole-heart images were successfully acquired with no visible image artifact in the vicinity of the coronary veins. The anatomical features and visual grading of both techniques were comparable. However, the targeted small slab acquisition of the left ventricular lateral wall was superior to whole-heart acquisition for visualization of relevant information for cardiac resynchronization therapy (CRT) lead implantation. We demonstrated the feasibility of whole-heart coronary vein MRI using a 3D MT-SSFP imaging sequence. A targeted acquisition along the lateral left ventricular wall is preferred for visualization of branches commonly used in CRT lead implantation.

    Characterization of myocardial structural changes in heart failure with preserved ejection fraction (HFpEF) has been hindered by the limited availability of human cardiac tissue. Cardiac hypertrophy, coronary artery disease (CAD), coronary microvascular rarefaction, and myocardial fibrosis may contribute to HFpEF pathophysiology. We identified HFpEF patients (n=124) and age-appropriate control subjects (noncardiac death, no heart failure diagnosis; n=104) who underwent autopsy. Heart weight and CAD severity were obtained from the autopsy reports. With the use of whole-field digital microscopy and automated analysis algorithms in full-thickness left ventricular sections, microvascular density (MVD), myocardial fibrosis, and their relationship were quantified. Subjects with HFpEF had heavier hearts (median, 538 g; 169% of age-, sex-, and body size-expected heart weight versus 335 g; 112% in controls), more severe CAD (65% with ≥1 vessel with >50% diameter stenosis in HFpEF versus 13% in controls), more left ventricular fibrosis (median % area fibrosis, 9.6 versus 7.1) and lower MVD (median 961 versus 1316 vessels/mm(2)) than control (Pcoronary microvascular rarefaction, and myocardial fibrosis than controls. Each of these findings may contribute to the left ventricular diastolic dysfunction and cardiac reserve function impairment characteristic of HFpEF. © 2014 American Heart Association, Inc.

    To evaluate the impact the National Service Framework (NSF) for coronary heart disease has had on emergency treatment and outcomes in patients presenting with acute coronary syndromes. Retrospective cohort study. Coronary care units of two district general hospitals. Data from 3371 patients were recorded, 1993 patients in the 27 months before the introduction of the NSF and 1378 patients in the 24 months afterwards. After the introduction of the NSF in-hospital mortality was significantly reduced (95 patients (4.8%) v 43 (3.2%), p = 0.02). This was associated with a reduction in the development of Q wave myocardial infarction (40.6% v 33.3%, p < 0.0001) and in the incidence of left ventricular failure (15.9% v 12.3%, p = 0.003). The proportion of patients receiving thrombolysis increased (69.4% v 84.7%, p < 0.0001) with a decrease in the time taken to receive it (proportion thrombolysed within 20 minutes 12.1% v 26.6%, p < 0.0001). The prescription of beta blockers (51.9% v 65.8%, p < 0.0001), angiotensin converting enzyme inhibitors (37% v 66.4%, p < 0.0001), and statins (55.2% v 72.7%, p < 0.0001) improved and the proportion of patients referred for invasive investigation increased (18.3% v 27.0%, p < 0.0001). Trend analysis showed that improvements in mortality and thrombolysis were directly associated with publication of the NSF, whereas the improvements seen in prescription of beta blockers and statins were the continuation of pre-existing trends. In the two years that followed publication of the NSF the initial treatment and outcome of patients presenting with acute coronary syndromes improved. Some of the improvements can be attributed to the NSF but others are continuations of pre-existing trends.

    Full Text Available Cardiovascular disease (including coronary artery disease and myocardial infarction is one of the leading causes of death in Europe, and is influenced by both environmental and genetic factors. With the recent advances in genomic tools and technologies there is potential to predict and diagnose heart disease using molecular data from analysis of blood cells. We analyzed gene expression data from blood samples taken from normal people (n = 21, non-significant coronary artery disease (n = 93, patients with unstable angina (n = 16, stable coronary artery disease (n = 14 and myocardial infarction (MI; n = 207. We used a feature selection approach to identify a set of gene expression variables which successfully differentiate different cardiovascular diseases. The initial features were discovered by fitting a linear model for each probe set across all arrays of normal individuals and patients with myocardial infarction. Three different feature optimisation algorithms were devised which identified two discriminating sets of genes, one using MI and normal controls (total genes = 6 and another one using MI and unstable angina patients (total genes = 7. In all our classification approaches we used a non-parametric k-nearest neighbour (KNN classification method (k = 3. The results proved the diagnostic robustness of the final feature sets in discriminating patients with myocardial infarction from healthy controls. Interestingly it also showed efficacy in discriminating myocardial infarction patients from patients with clinical symptoms of cardiac ischemia but no myocardial necrosis or stable coronary artery disease, despite the influence of batch effects and different microarray gene chips and platforms.

    Coronary heart disease (CHD) is the single most common cause of death globally. However, with falling CHD mortality rates, an increasing number of people live with CHD and may need support to manage their symptoms and improve prognosis. Cardiac rehabilitation is a complex multifaceted intervention which aims to improve the health outcomes of people with CHD. Cardiac rehabilitation consists of three core modalities: education, exercise training and psychological support. This is an update of a Cochrane systematic review previously published in 2011, which aims to investigate the specific impact of the educational component of cardiac rehabilitation. 1. To assess the effects of patient education delivered as part of cardiac rehabilitation, compared with usual care on mortality, morbidity, health-related quality of life (HRQoL) and healthcare costs in patients with CHD.2. To explore the potential study level predictors of the effects of patient education in patients with CHD (e.g. individual versus group intervention, timing with respect to index cardiac event). We updated searches from the previous Cochrane review, by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library, Issue 6, 2016), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) in June 2016. Three trials registries, previous systematic reviews and reference lists of included studies were also searched. No language restrictions were applied. 1.

    We evaluated the clinical efficacy and cost of a cardiac imaging strategy versus a traditional exercise tolerance test (ETT) strategy for the investigation of suspected stable coronary artery disease (CAD). We retrospectively collected data of consecutive patients seen in rapid access chest pain clinics at 2 UK hospitals for a period of 12 months. Hospital A investigated patients by performing ETT. Hospital B investigated patients using cardiac imaging test; 483 patients from hospital A and 295 from hospital B were included. In hospital A, 209 patients (43.3%) had contraindication to ETT. Of those who had ETT, 151 (55.1%) had negative ETT, 68 (24.8%) had equivocal ETT, and 55 (20.1%) had positive ETT, of which 53 (96.4%) had invasive coronary angiography (ICA), and of these 23 (43.4%) had obstructive CAD. In hospital B, 26 patients (8.8%) with low pretest probability had calcium score and 3 (11.5%) were positive leading to computed tomography coronary angiography; 98 patients (33.2%) with intermediate pretest probability had computed tomography coronary angiography and 5 (5.1%) were positive; 77 patients (26.1%) had stress echocardiogram and 6 (7.8%) were positive; and 57 patients (19.3%) had myocardial perfusion scintigraphy and 11 (19.3%) were positive. Hospital A performed 127 ICA (26.3% of population) and 52 (40.9%) had obstructive CAD. Hospital B performed 63 ICA (21.4% of population) and 32 (50.8%) had obstructive CAD. The average cost per patient in hospital A was £566.6 ± 490.0 ($875 ± 758) and in hospital B was £487.9 ± 469.6 ($750 ± 725) (p <0.001). In conclusion, our results suggest that a cardiac imaging pathway leads to fewer ICA and a higher yield of obstructive CAD at lower cost per patient. Copyright © 2015 Elsevier Inc.

    Most cardiovascular disease (CVD) occurs in patients over the age of 60. However, most evidence-based current cardiovascular guidelines lack evidence in an older population, due to the under-representation of older patients in randomised trials. Blood pressure rises with age due to increasing arterial stiffness, and stricter control results in improved outcomes. Myocardial ischaemia is also more common with increasing age, due to a combination of coronary artery disease and myocardial changes. However, despite higher rates of adverse outcomes, older patients are offered guideline-based therapy less frequently. Frailty is an independent predictor of mortality in adults over the age of 60, yet remains poorly assessed; slow gait speed is a key marker for the development of frailty and for adverse outcomes following intervention. Few trials have assessed frailty independent of age; however, there is evidence that non-frail older patients derive significant benefit from therapy, highlighting the urgent need to include frailty as a measure in clinical trials of treatment in CVD.In this review, the authors appraise the literature in regard to the cardiovascular changes with ageing, specifically in relation to the systemic and coronary circulation and with a particular emphasis on frailty and its implication in the evaluation and treatment of CVD. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Anomalous coronary arteries originating from the opposite sinus of Valsalva (ACAOS) are associated with adverse cardiac events. Discrimination between ACAOS and coronary artery disease (CAD)-related perfusion defects may be difficult. The aim of the present study was to investigate the value of hybrid coronary computed tomography angiography (CCTA)/SPECT-MPI in patients with ACAOS and possible concomitant CAD. We retrospectively identified 46 patients (mean age 56 ± 12 years) with ACAOS revealed by CCTA who underwent additional SPECT-MPI. ACAOS with an interarterial course were classified as malignant, whereas all other variants were considered benign. CCTA/SPECT-MPI hybrid imaging findings (ischemia or scar) were analyzed according to the territory subtended by an anomalous vessel or a stenotic coronary artery. Twenty-six (57%) patients presented with malignant ACAOS. Myocardial ischemia or scar was found only in patients who had concomitant obstructive CAD in the vessel matching the perfusion defect as evidenced by hybrid CCTA/SPECT imaging. Hybrid CCTA/SPECT-MPI represents a valuable non-invasive tool to discriminate the impact of ACAOS from concomitant CAD on myocardial ischemia. Our results suggest that in a middle-aged population myocardial ischemia due to ACAOS per se may be exceedingly rare and is more likely attributable to concomitant CAD.

    Full Text Available Pathological gamblers, because of their high level of stress, depression and alcohol or nicotine consumption may be overexposed to coronary heart disease (CHD. To test this association, we assessed pathological gambling (DSM-IV-TR criteria and SOGS scale among 73 patients hospitalized in cardiology for CHD and 61 in-patients from the same department hospitalized for a non coronary disorder. We found six cases of PG (8.2% and one case of problem gambling in the CHD group versus no case in the non-coronary group (p=0.01. Pathological gambling was not associated to a higher level of alcohol or nicotine consumption neither to a higher level of sensation-seeking.

    Blood plasma can be considered as a special water system with self-organization possibilities. Plasma slides as the results of wedge dehydration reflect its stereochemical interaction and their study can be used in diagnostic processes. 46 patients with coronary heart disease were studied. The main group was formed of men in age ranged from 54 to 72 years old with stable angina pectoris of II and III functional class (by Canadian classification) (n=25). The group of compare was of those who was hospitalized with diagnosis of acute coronary syndrome, men in age range 40-82. Clinical examination, basic biochemical tests and functional plasma morphology characteristics were studied. A number of qualitative and quantitative differences of blood plasma morphology of patients with chronic and acute coronary disease forms was revealed.

    Full Text Available Coronary computed tomographic angiography (CCTA facilitates comprehensive evaluation of coronary artery disease (CAD, including plaque characterization, and can provide additive diagnostic value to single-photon emission computed tomography (SPECT. However, data regarding the incremental prognostic value of CCTA to SPECT remain sparse. We evaluated the independent and incremental prognostic value of CCTA, as compared with clinical risk factors and SPECT.A total of 1,077 patients with suspected CAD who underwent both SPECT and cardiac CT between 2004 and 2012 were enrolled retrospectively. Presence of reversible or fixed perfusion defect (PD and summed stress score were evaluated on SPECT. Presence, extent of coronary atherosclerosis and diameter stenosis (DS were evaluated on CCTA. Plaque composition was categorized as non-calcified, mixed, or calcified according to the volume of calcified component (>130 Hounsfield Units. Patients were followed up for the occurrence of adverse cardiac events including cardiac death, non-fatal myocardial infarction, unstable angina, and late revascularization (>90 days after imaging studies.During follow-up (median 23 months, adverse cardiac events were observed in 71 patients (6.6%. When adjusted for clinical risk factors and SPECT findings, the presence of any coronary plaque, any plaque in ≥3 segments, coronary artery calcium score (CACS ≥400, a plaque ≥50% DS, presence of non-calcified plaque (NCP or mixed plaque (MP, and NCP/MP in ≥2 segments were independent predictors of adverse cardiac events; however, the presence of calcified plaque (CP was not. Conventional CCTA findings, including CACS ≥400 and a plaque ≥50% DS, demonstrated incremental prognostic value over clinical risk factors and SPECT (χ² 54.19 to 101.03; p <0.001.

    The main objective of this study is to investigate the relationship between ascending aorta elasticity and the severity of coronary artery stenosis in essential hypertensive patients with coronary heart disease (CHD) using M-mode and tissue Doppler echocardiography. A total of 184 hypertensive patients with CHD were enrolled. Patients were divided into three groups based on the severity of coronary stenosis measured by coronary arteriography (CAG): slight stenosis (group 1), moderate stenosis (group 2) and serious stenosis (group 3). M-mode and tissue Doppler echocardiography were performed, and elasticity indexes of ascending aorta including stiffness index, distensibility index, and S wave speed of anterior wall were calculated and correlated with the severity of coronary stenosis. Ascending aorta stiffness index was increased, whereas distensibility index and S wave speed of anterior wall were decreased in moderate and severe stenosis groups compared with slight stenosis group (P Elasticity indexes change in a stepwise pattern with the narrowness of coronary artery, and there was a significant correlation between aortic elasticity and severity of coronary artery by Pearson correlation analysis (P Elasticity indexes of ascending aorta correlate well with severity of coronary stenosis. Elasticity indexes of ascending aorta can serve as predictors for coronary arterial lesion in hypertensive patients.

  6. The role of Homocysteine as a predictor for coronary heart disease

    Directory of Open Access Journals (Sweden)

    Schramm, Susanne

    2007-11-01

    Full Text Available Background and objective: There is an ongoing debate on the role of the cytotoxic aminoacid homocysteine as a causal risk factor for the development of coronary heart disease. Results from multiple case control-studies demonstrate, that there is a strong association between high plasma levels of homoysteine and prevalent coronary heart disease, independent of other classic risk factors. Furthermore, results from interventional studies point out that elevated plasma levels of homocysteine may effectively be lowered by the intake of folic acid and B vitamins. In order to use this information for the construction of a new preventive strategy against coronary heart disease, more information is needed: first, whether homocysteine actually is a causal risk factor with relevant predictive properties and, second, whether by lowering elevated homocysteine plasma concentrations cardiac morbidity can be reduced. Currently in Germany the determination of homocysteine plasma levels is reimbursed for by statutory health insurance in patients with manifest coronary heart disease and in patients at high risk for coronary heart disease but not for screening purposes in asymptomatic low risk populations.Against this background the following assessment sets out to answer four questions: 1. Is an elevated homocysteine plasma concentration a strong, consistent and independent (of other classic risk factors predictor for coronary heart disease? 2. Does a therapeutic lowering of elevated homoysteine plasma levels reduce the risk of developing coronary events? 3. What is the cost-effectiveness relationship of homocysteine testing for preventive purposes? 4. Are there morally, socially or legally relevant aspects that should be considered when implementing a preventive strategy as outlined above? Methods: In order to answer the first question, a systematic overview of prospective studies and metaanalyses of prospective studies is undertaken. Studies are included that

    2010-01-01

    Full Text Available Heart disease is the first killer of women in the modern era, regardless of age, race and of ethnicity, although its prevalence rises after menopause. Modern women have professional and housewife responsibilities, consume excess of fat and carbohydrates, smoke, do not exercise regularly and do not have enough time to rest. This situation leads to overweight, dyslipidemia, arterial hypertension, impaired glucose tolerance and diabetes. Women do not often participate in preventive studies and still undergo less intensive and invasive evaluation and treatment for chest pain when compared to men. However, the rate of coronary death is twice higher in women than in men after myocardial infarction and revascularization procedures. The objective of this review is to analyze the main gender differences regarding symptoms, diagnosis, management and prognosis of coronary heart disease and to discuss the influence of hormonal replacement therapy in the prevention of cardiovascular disease in postmenopausal women.

    Generalized anxiety disorder prevalence and comorbidity with depression in coronary heart disease patients remain unquantified. Systematic searching of Medline, Embase, SCOPUS and PsycINFO databases revealed 1025 unique citations. Aggregate generalized anxiety disorder prevalence (12 studies, N = 3485) was 10.94 per cent (95% confidence interval: 7.8-13.99) and 13.52 per cent (95% confidence interval: 8.39-18.66) employing Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria (random effects). Lifetime generalized anxiety disorder prevalence was 25.80 per cent (95% confidence interval: 20.84-30.77). In seven studies, modest correlation was evident between generalized anxiety disorder and depression, Fisher's Z = .30 (95% confidence interval: .19-.42), suggesting that each psychiatric disorder is best conceptualized as contributing unique variance to coronary heart disease prognosis.

    The aim of study was to examine echocardiographic indices of right heart chambers in patients with coronary artery disease in different age groups. On 678 patients aged 38-85 years, who underwent echocardiography, are including with the use of spectral tissue Doppler. Obtained 2 age groups: 1st - patients up to 60 years (n=282) and group 2nd - patients 60 years and older (n=396). In the analysis the obtained results in patients with coronary heart disease in older age groups showed an increase in right ventricular wall thickness, systolic and average pressure in the pulmonary artery. These changes were accompanied by deterioration in left ventricular diastolic function, while the systolic function of the left and right ventricle were independent of age. Thus, the results can be recommended for assessment of right ventricular dysfunction in patients of older age groups.

    Coronary heart disease (CHD) is a disease that causes narrowing of the coronary arteries. Currently, there is a hypothesis regarding periodontal infection that increases risk for heart disease. Alkaline phosphatase (ALP) as a marker of inflammation will increase in atherosclerosis and periodontal disease. The objective of this research is analyzing the relationship between the levels of alkaline phosphatase in saliva with periodontal status in patients with CHD and non CHD. Here, saliva of 104 subjects were taken, each 1 ml, and levels of Alkaline Phosphatase was analyzed using Abbott ci4100 architect. We found that no significant difference of Alkaline Phosphatase levels in saliva between CHD patients and non CHD. Therefore, it can be concluded that Alkaline Phosphatase levels in patients with CHD saliva was higher than non CHD and no association between ALP levels with periodontal status.

    Air pollution exposure increases cardiovascular morbidity and mortality and is a major global public health concern. We investigated the benefits of reducing personal exposure to urban air pollution in patients with coronary heart disease. In an open randomized crossover trial, 98 patients with coronary heart disease walked on a predefined route in central Beijing, China, under different conditions: once while using a highly efficient face mask, and once while not using the mask. Symptoms, exercise, personal air pollution exposure, blood pressure, heart rate, and 12-lead electrocardiography were monitored throughout the 24-hr study period. Ambient air pollutants were dominated by fine and ultrafine particulate matter (PM) that was present at high levels [74 μg/m³ for PM(2.5) (PM with aerodynamic diamater reduced maximal ST segment depression (-142 vs. -156 μV, p = 0.046) over the 24-hr period. When the face mask was used during the prescribed walk, mean arterial pressure was lower (93 ± 10 vs. 96 ± 10 mmHg, p = 0.025) and heart rate variability increased (high-frequency power: 54 vs. 40 msec², p = 0.005; high-frequency normalized power: 23.5 vs. 20.5 msec, p = 0.001; root mean square successive differences: 16.7 vs. 14.8 msec, p = 0.007). However, mask use did not appear to influence heart rate or energy expenditure. Reducing personal exposure to air pollution using a highly efficient face mask appeared to reduce symptoms and improve a range of cardiovascular health measures in patients with coronary heart disease. Such interventions to reduce personal exposure to PM air pollution have the potential to reduce the incidence of cardiovascular events in this highly susceptible population.

    The nucleoside and nucleotide reverse transcriptase inhibitor (N[t]RTI) drug class remains an integral component of effective antiretroviral therapy (ART) for human immunodeficiency virus (HIV) infection. However, these drugs are associated with toxicities, through their off-target effects, that may significantly contribute to a number of long-term comorbidities, including coronary artery disease (CAD) and myocardial infarction (MI), recognized to occur with increased frequency in those with HIV undergoing treatment with ART. The contribution of N(t)RTI to CAD and MI may arise either indirectly through induction of metabolic toxicities such as dyslipidemia and insulin resistance, or directly through impact on pathologic pathways involved in development of MI, such as altered platelet responsiveness or endothelial dysfunction. This review focuses on the available data relating to use of individual N(t)RTI drugs and the drug class as a whole and CAD, with a focus on MI.

  17. Social Support, Unstable Angina, and Stroke as Predictors of Depression in Patients With Coronary Heart Disease.

    Science.gov (United States)

    Su, Shu-Fen; Chang, Mei-Yu; He, Chung-Ping

    Depression is known to adversely affect coronary heart disease patients in western countries; however, no study of social support and depression has been conducted in the Chinese population. The aim of this study was to investigate the predictors of depression in patients with coronary heart disease. Between January and December 2015, a cross-sectional sample of 105 Taiwanese patients from cardiology units completed a demographic and clinical characteristics questionnaire, Enhancing Recovery in Coronary Heart Disease Social Support Inventory, and Patient Health Questionnaire-9. Thirty-nine percent of the participants reported low social support, and 61.0% had depression symptoms. Eight factors predicted depression. Social support was significantly and adversely correlated with depression (r = -.481, P < .01). The other 7 factors were positively correlated with depression: age (r = .212, P < .05), reported monthly income of less than US $600 (F = 4.98, P = .001), lack of exercise (F = 3.75, P = .027), history of stroke (t = -2.45, P = .016) and kidney disease (t = -2.41, P = .018), unstable angina (F = 3.56, P = .031), and groin puncture (F = 3.27, P = .042). A hierarchical regression model explained 43.7% of the variance in depression. Social support, unstable angina, and stroke may be important predictors of depression in patients with coronary heart disease. These findings help clinical staff to understand physical and mental health problems in cardiovascular patients. Thus, we suggest that early depression prediction and sufficient social support can help patients to face their disease and thus improve depression and health care quality.

    2017-01-01

    Abstract Background: We aimed to quantitatively assess the potential relationship between kidney stones and coronary heart disease or stroke. Methods: A meta-analysis was conducted on eligibly studies published before 31 May 2016 in PubMed or Embase. The data were pooled, and the relationship was assessed by the random-effect model with inverse variance-weighted procedure. The results were expressed as relative risk (RR) with 95% confidence intervals (95%CI). Results: Eight studies of 11 cohorts (n = 11) were included in our analysis with 3,658,360 participants and 157,037 cases. We found that a history of kidney stones was associated with increased risk of coronary heart disease (CHD) (RR = 1.24; 95%CI: 1.14–1.36; I2 = 79.0%, n = 11); similar effect on myocardial infarction, a serious condition of CHD, was observed (RR = 1.24; 95%CI: 1.10–1.40; I2 = 80.4%, n = 8). We also found that a history of kidney stones may increase the risk of stroke (RR = 1.21, 95%CI: 1.06–1.38; I2 = 54.7%, n = 4). In subgroup analysis, the risk of coronary heart disease was higher in men (RR = 1.23, 95%CI: 1.02–1.49) while the risk for stroke was higher in women (RR = 1.12; 95%CI: 1.03–1.21). No obvious publications bias was detected (Egger test: P = .47). Conclusion: Kidney stones are associated with increased risk of coronary heart disease and stroke, and the effect may differ by sex.

    There is evidence about a possible relationship existing between periodontal diseases and coronary heart disease. The aim of the present longitudinal study was to investigate the changes in periodontal evolution after etiological periodontal treatment, comparing a healthy control group with another having coronary heart disease. The study included initially 55 patients of which 44 finished it. They were placed into two groups: Healthy Control Group (HCG) n =9, and Coronary Heart Disease Group (CHDG) n=35. The gingival level (GL), probing depth (PD), clinical attachment level (CAL), plaque index (PI) and bleeding on probing (BOP) were measured to compare the periodontal status in both groups. The patients were examined and etiological periodontal treatment was performed and they were then examined at the end of 1 and 10 years. A one way-ANOVA and a MR-ANOVA were established; significance p0.5). However, at the second visit the CHDG presented a significantly higher PD (p<0.05) and PI (p<0.01). CHDG patients gradually increase PD through time and in comparison to the control group (p<0.041). CHDG patients present a significantly higher CAL loss (p<0.0385) and a significant increase in PI (p<0.0041) at the end of one year, while on the third visit no significant differences were detected in any of these indices. Likewise, a similar fact can be observed on evaluating BOP at the end of ten years causal treatment, a smaller decrease in the cardiac group was observed in regards to the initial values (p<0.001). Patients with coronary heart disease showed a worse evolution of periodontal indices than healthy ones, when referring to probing depth, plaque index and bleeding on probing index.

    Full Text Available Cardiac magnetic resonance imaging (CMR has an important emerging role in the evaluation and management of patients who present with symptoms concerning for acute coronary syndrome (ACS. This paper discusses the role of CMR in the emergency department setting, where CMR can aid in the early and accurate diagnosis of non-ST elevation ACS in low and intermediate risk patients. For those with confirmed myocardial infarction (MI, CMR provides comprehensive prognostic information and can readily diagnose structural complications related to MI. Furthermore, the pattern of late gadolinium enhancement (LGE seen on CMR can help determine the etiology of cardiac injury in the subset of patients presenting with ACS who do not have obstructive coronary artery disease by angiography.

    To assess the relationship of parameters of obesity in relationship to coronary angiography findings with correlation of epicardial fat (EF) thickness in uppermentioned context. There were 80 patients examined (43 males, 37 postmenopausal females) undergoing elective coronary angiography. We examined the regular obesity parameters - BMI, waist circumference (WC), neck circumference (NC), total body fat (TBF), and visceral fat (VF) using bioimpedance. We assessed the echocardiographically measured EF thickness. We added examination of lipidogram, glycaemia, HOMA-IR (insulin resistance index) and AIP (aterogenic index of plasma). The set was divided into group with coronarographically proved stenosis or stenoses (withCS), and a group without finding of quantifiable stenosis or stenoses (withoutCS). The average thickness of EF in withCS group was 6.3 vs 5.6 mm in group withoutCS (p obesity parameters in assessment of pre-clinical stages of coronary atherosclerosis and prediction of risk of coronary heart disease. In adipose parameters, EF thickness was correlated the most by WC. Risk stratification of coronary artery disease is supplemented by increased HOMA-IR and AIP.

    Abnormal lipid composition and metabolism of plasma lipoproteins play a crucial role in the pathogenesis of coronary heart disease (CHD). A (1)H NMR-based lipidomic approach was used to investigate the correlation of coronary artery stenosis with the atherogenic (non-HDL) and atheroprotective (HDL) lipid profiles in 99 patients with CHD of various stages of disease and compared with 60 patients with normal coronary arteries (NCA), all documented in coronary angiography. The pattern recognition models created from lipid profiles predicted the presence of CHD with a sensitivity of 87% and a specificity of 88% in the HDL model and with 90% and 89% in the non-HDL model, respectively. Patients with mild, moderate, and severe coronary artery stenosis were progressively differentiated from those with NCA in the non-HDL model with a statistically significant separation of severe stage from both mild and moderate. In the HDL model, the progressive differentiation of the disease stages was statistically significant only between patients with mild and severe coronary artery stenosis. The lipid constituents of lipoproteins that mainly characterized the initial stages and then the progression of the disease were the high levels of saturated fatty acids in lipids in both HDL and non-HDL particles, the low levels of HDL-phosphatidylcholine, HDL-sphingomyelin, and omega-3 fatty acids and linoleic acid in lipids in non-HDL particles. The conventional lipid marker, total cholesterol, found in low levels in HDL and in high levels in non-HDL, also contributed to the onset of the disease but with a much lower coefficient of significance. (1)H NMR-based lipidomic analysis of atherogenic and atheroprotective lipoproteins could contribute to the early evaluation of the onset of coronary artery disease and possibly to the establishment of an appropriate therapeutic option.

    At present, limited in vivo information is available on the prevalence and severity of coronary atherosclerosis in asymptomatic healthy subjects. The aim of this study was to examine the prevalence, extent and severity of coronary atherosclerosis in healthy individuals. We performed an intravascular ultrasound (IVUS) examination on 198 heart transplant recipients 4 weeks after transplantation. The donor population consisted of 147 men and 51 women (31.4±11.0 years). The left anterior descending coronary artery was imaged in all patients, and 3 vessel images were obtained for 99 patients. Angiographic appearance was completely normal in 177 of the 198 subjects (89.4%), while atherosclerotic luminal irregularities were observed in the remaining individuals. IVUS revealed that atherosclerotic lesions (defined as intimal thickness ≥0.5 mm at any site) were present in 96 patients (48.5%). The prevalence of coronary atherosclerosis rapidly increased with age (10-19 years, 5.9%; 20-29 years, 31.1%; 30-39 years, 59.0%; 40-49 years, 78.4%). In the diseased subgroup, atherosclerotic lesions were mostly eccentric (92.7%), with maximal intimal thickness of 0.99±0.42 mm (area stenosis, 32.2±11.7%). All coronary arteries were predominantly located in the proximal third of each vessel. Donor age, male sex, and hypertension were the determinants of coronary atherosclerosis measured by IVUS examination. As more risk factors were present, the risk of atherosclerosis increased. Coronary atherosclerosis is common in asymptomatic young healthy adults, supporting the need for preventive cardiology in the early stages of life.

    Computed tomography coronary angiography patient preparation with heart rate control premedication is employed in departments across Australia. However, the methods of administration vary widely between institutions and do not always follow best practice. This aim of the study was to identify and promote best practice in the administration of heart rate premedication in computed tomography coronary angiography at a regional hospital in Australia. The Joanna Briggs Institute have validated audit and feedback tools to assist with best practice implementation projects. This project used these tools, which involve three phases of activity - a pre-implementation audit, reflecting on results and implementing strategies to address non-compliance, and a post-implementation audit to assess the outcomes. A baseline audit identified non-compliance in the majority of measured audit criteria. Following implementation of an institution-specific guideline and associated worksheet, improved compliance was shown across all audit criteria. Following the development and implementation of institution-specific evidence-based resources relating to heart rate control in computed tomography coronary angiography, a high level of compliance consistent with best practice was achieved.

  12. Quantitative Determination of Fibrinogen of Patients with Coronary Heart Diseases through Piezoelectric Agglutination Sensor

    Full Text Available Fibrinogen can transform fibrin through an agglutination reaction, finally forming fibrin polymer with grid structure. The density and viscosity of the reaction system changes drastically during the course of agglutination. In this research, we apply an independently-developed piezoelectric agglutination sensor to detect the fibrinogen agglutination reaction in patients with coronary heart diseases. The terminal judgment method of determining plasma agglutination reaction through piezoelectric agglutination sensor was established. In addition, the standard curve between plasma agglutination time and fibrinogen concentration was established to determinate fibrinogen content quantitatively. The results indicate the close correlation between the STAGO paramagnetic particle method and the method of piezoelectric agglutination sensor for the detection of Fibrinogen. The correlation coefficient was 0.91 (γ = 0.91. The determination can be completed within 10 minutes. The fibrinogen concentration in the coronary heart disease group was significantly higher than that of the healthy control group (P < 0.05. The results reveal that high fibrinogen concentration is closely correlated to the incurrence, development and prognosis of coronary heart diseases. Compared with other traditional methods, the method of piezoelectric agglutination sensor has some merits such as operation convenience, small size, low cost, quick detecting, good precision and the common reacting agents with paramagnetic particle method.

    Adherence to a healthy dietary pattern, such as the Mediterranean diet, exerts a beneficial role regarding the development of coronary heart disease. In addition, several studies support the protective role of the Mediterranean diet as far as obesity is concerned. This review, examining results from prospective cohort and cross-sectional studies, as well as clinical trials, aims to clarify whether the beneficial effect of the Mediterranean dietary pattern on coronary heart disease is due to the impact of this diet on weight loss and obesity status or an independent effect. 35 original-research studies that were published in English until 2009, selected through a computer-assisted literature search are discussed, from which 3 were prospective, 11 were cross-sectional studies, and 21 were clinical trials. Although not all studies show a protective effect of the Mediterranean diet on body weight and obesity, the evidence suggests a possible beneficial role of this dietary pattern. Thus the Mediterranean diet protects against the development of coronary heart disease not only because of its beneficial role regarding cardiovascular risk factors, but also due to a possible effect on body weight and obesity.

    Rayner, Mike; Scarborough, Peter; Allender, Steven

    2006-04-01

    The National Service Framework (NSF) for Coronary Heart Disease--published by the English Department of Health in 2000--sets out how those within the health service should seek to prevent and treat coronary heart disease and care for people with the disease. Its prescriptions are partly based on what is known about coronary heart disease and partly on its underlying 'values'. This paper seeks to identify those values. An analysis of the discourses within the text of the NSF based on critical discourse analysis. Three different discourses can be identified: the managerial, the clinical and the political. The managerial discourse is dominant. Each discourse has its own values. The main 'aspirational' values within the NSF are efficiency, effectiveness, autonomy (choice), universalism and equity. Some aspirational values--particularly equity--appear to be largely rhetorical and lead to few recommendations or prescriptions. Some values that might have been expected to underlie the framework, such as compassion and democracy, are largely absent. Discourse analysis provides a more systematic and transparent method of describing the values behind health care policy than the methods that have been used previously.

    Cataldo, S; Stuart, A G

    2014-10-01

    There are a wide variety of coronary artery anomalies and disease in adults with congenital heart disease (CHD). In fact, the increasing burden of acquired coronary artery disease (CAD) has to be considered in addition to congenital abnormalities of the coronary arteries, isolated or associated to other congenital diseases. This is largely a consequence of the increasing number of patients reaching older age. Due to complex underlying cardiac anatomy, previous surgery and comorbidities, treatment can be challenging. Individualized and multidisciplinary management involving congenital heart cardiologists, cardiac surgeons, coronary interventionists and imaging specialists is essential. This review gives an overview of coronary artery involvement in adults with CHD, summarizes the current literature and focuses on prevention, diagnosis and treatment. The potential role of cardiovascular risk factors for CAD is also discussed.

    Under the available data gathered from a coronary study questionnaires with 10 792 cases, this article constructs a Bayesian network model based on the tabu search algorithm and calculates the conditional probability of each node, using the Maximum-likelihood. Pros and cons of the Bayesian network model are evaluated to compare against the logistic regression model in the analysis of coronary factors. Applicability of this network model in clinical study is also investigated. Results show that Bayesian network model can reveal the complex correlations among influencing factors on the coronary and the relationship with coronary heart diseases. Bayesian network model seems promising and more practical than the logistic regression model in analyzing the influencing factors of coronary heart disease.

    The prevalence of coronary artery disease (CAD) in valvular patients is similar to that of the general population, with the usual association with traditional risk factors. Nevertheless, the search for obstructive CAD is more aggressive in the preoperative period of patients with valvular heart disease, resulting in the indication of invasive coronary angiography (ICA) to almost all adult patients, because it is believed that coronary artery bypass surgery should be associated with valve replacement. To evaluate the prevalence of obstructive CAD and factors associated with it in adult candidates for primary heart valve surgery between 2001 and 2014 at the National Institute of Cardiology (INC) and, thus, derive and validate a predictive obstructive CAD score. Cross-sectional study evaluating 2898 patients with indication for heart surgery of any etiology. Of those, 712 patients, who had valvular heart disease and underwent ICA in the 12 months prior to surgery, were included. The P value arterial hypertension, diabetes mellitus, dyslipidemia, smoking, and male gender. The model showed excellent correlation and calibration (R² = 0.98), as well as excellent accuracy (ROC of 0.848; 95%CI: 0.817-0.879) and validation (ROC of 0.877; 95%CI: 0.830 - 0.923) in different valve populations. Obstructive CAD can be estimated from clinical data of adult candidates for valve repair surgery, using a simple, accurate and validated score, easy to apply in clinical practice, which may contribute to changes in the preoperative strategy of acquired heart valve surgery in patients with a lower probability of obstructive disease.

    Full Text Available Background. Asymmetric dimethylarginine (ADMA is an endogenous inhibitor of nitric oxide synthase. A previous rat study revealed an ADMA lowering effect following treatment with omega-3 polyunsaturated fatty acids (n-3 PUFAs. We sought to examine if an association between plasma ADMA and risk of acute myocardial infarction (AMI was modified by serum n-3 PUFA status. Methods. The cohort included 1364 patients who underwent coronary angiography for suspected coronary artery disease in 2000-2001. Fatal and nonfatal AMI events were registered until December 31, 2006. Risk associations with AMI were estimated across ADMA quartiles (linear trend and the upper decile. Results. No association between concentration of any n-3 PUFA and ADMA was observed. Only ADMA levels in upper decile were significantly associated with AMI with a multivariate adjusted hazard ratio (HR (95% confidence interval versus the rest of the population of 2.11 (1.34, 3.32. The association was strengthened among patients with below median levels of α-linolenic acid (ALA (HR 3.12 (1.64, 5.93, but was only influenced by longer chain n-3 PUFA after additional adjustments for HbA1c, estimated glomerular filtration rate, and hypercholesterolemia. Conclusions. The association of ADMA with risk of AMI is influenced by serum n-3 PUFA and particularly ALA.

    Traditional prognostic risk assessment in patients undergoing non-invasive imaging is based upon a limited selection of clinical and imaging findings. Machine learning (ML) can consider a greater number and complexity of variables. Therefore, we investigated the feasibility and accuracy of ML to predict 5-year all-cause mortality (ACM) in patients undergoing coronary computed tomographic angiography (CCTA), and compared the performance to existing clinical or CCTA metrics. The analysis included 10 030 patients with suspected coronary artery disease and 5-year follow-up from the COronary CT Angiography EvaluatioN For Clinical Outcomes: An InteRnational Multicenter registry. All patients underwent CCTA as their standard of care. Twenty-five clinical and 44 CCTA parameters were evaluated, including segment stenosis score (SSS), segment involvement score (SIS), modified Duke index (DI), number of segments with non-calcified, mixed or calcified plaques, age, sex, gender, standard cardiovascular risk factors, and Framingham risk score (FRS). Machine learning involved automated feature selection by information gain ranking, model building with a boosted ensemble algorithm, and 10-fold stratified cross-validation. Seven hundred and forty-five patients died during 5-year follow-up. Machine learning exhibited a higher area-under-curve compared with the FRS or CCTA severity scores alone (SSS, SIS, DI) for predicting all-cause mortality (ML: 0.79 vs. FRS: 0.61, SSS: 0.64, SIS: 0.64, DI: 0.62; PMachine learning combining clinical and CCTA data was found to predict 5-year ACM significantly better than existing clinical or CCTA metrics alone.

    Full Text Available Background/Aim. Numerous studies have provided clear and convincing evidence that psychosocial factors contribute to the pathogenesis and expression of coronary heart disease (CHD. These factors have been related to the following psychosocial domains: personality factors and character traits, depression, anxiety, social isolation and chronic life stress. The aim of this study was to estimate the influence of personality traits and psychosocial risk factors for the development of coronary heart disease. Methods. The investigation was conducted as observational cross-sectional (case-control study. Based on medical records all subjects were divided into two groups: the group of patients with CHD (61 participants, and the control group of 41 healthy participants. All participants fulfilled the Eysenck Inventory Questionnaire, Paykel stress scale and Bortner scale of A-B self-estimation. Results. The participants with CHD were shown to have lower education than healthy participants, but were comparable by gender, age and place of residence. According to the Bortner scale, most participants with CHD expressed type A personality, whereas most healthy participants expressed types B and AB. The patients with CHD achieved higher scores on the Paykel stress scale of life events, and they had the higher level of neurotic and psychotic tendencies, as well as the lower level of extroversion compared to the healthy participants. Multivariate logistic regression model identified chronic stress (odds ratio 1.018; 95% confidence interval 1.007−1.028 as an important predictor for the occurrence of coronary heart disease, when adjusted for age, gender, nourishment and blood pressure. On the other side, the lower risk for the occurrence of CHD was observed among the participants who had the higher level of extroversion (odds ratio 0.859; 95% confidence interval 0.636−0.902. Conclusion. Chronic stress and introversion can be considered important risk factors for

    When diagnosing the causes of acute chest pain, both acute coronary syndromes (ACSs) and other serious conditions should be considered. The aim of the study was to assess the usefulness of limited transthoracic echocardiography (TTE) with an A-F mnemonic in patients with suspected non-ST-segement elevation ACS (NSTE-ACS) and the effect of TTE on therapeutic decisions. This retrospective study was conducted at an emergency department for 12 months. The study population consisted of consecutive patients with a preliminary diagnosis of NSTE-ACS. We analyzed demographic data, clinical condition, medical history, electrocardiography, TTE, and the levels of necrotic markers. TTE with the A-F mnemonic was performed within 15 minutes from admission. A total of 916 consecutive patients were enrolled to the study. The diagnosis of ACS was confirmed in 70.19% of the patients. TTE with the A-F mnemonic revealed regional wall motion abnormalities in 74.03% of the ACS group and significant echocardiographic abnormalities in 2.18% of the ACS group and 55.31% of patients without ACS. On the basis of those findings, 4.69% of the patients underwent invasive treatment other than myocardial revascularization. A comparative analysis revealed that patients with ACS were older, more likely to have ST-segment depression, higher levels of necrotic markers, and lower left ventricular ejection fraction, while patients without ACS had more echocardiographic abnormalities in points B-F according to the A-F scheme. Limited TTE with the A-F mnemonic should be performed in all patients with suspected NSTE-ACS. It allows to confirm ischemia and detect other life-threatening conditions. TTE with the A-F mnemonic covers a sufficient spectrum of cardiac abnormalities and has a significant effect on therapeutic decision making in patients with suspected NSTE-ACS.

    Objectives To evaluate potential gaps in preventive medical therapy and healthy lifestyle practices among symptomatic patients with suspected coronary artery disease (CAD) seeing primary care physicians and cardiologists and how gaps vary by sociodemographic characteristics and baseline cardiovascular risk. Design Cross-sectional study assessing potential preventive gaps. Participants 10 003 symptomatic outpatients evaluated by primary care physicians, cardiologists or other specialists for suspected CAD. Setting PROspective Multicenter Imaging Study for Evaluation of Chest Painfrom 2010 to 2014. Measures Primary measures were absence of an antihypertensive, statin or angiotensin-converting enzyme inhibitor/angiotensin receptor blocker for renal protection in patients with hypertension, dyslipidaemia or diabetes, respectively, and being sedentary, smoking or being obese. Results Preventive treatment gaps affected 14% of patients with hypertension, 36% of patients with dyslipidaemia and 32% of patients with diabetes. Overall, 49% of patients were sedentary, 18% currently smoked and 48% were obese. Women were significantly more likely to not take a statin for dyslipidaemia and to be sedentary. Patients with lower socioeconomic status were also significantly more likely to not take a statin. Compared with Whites, Blacks were significantly more likely to be obese, while Asians were less likely to smoke or be obese. High-risk patients sometimes experienced larger preventive care gaps than low-risk patients. For patients with dyslipidaemia, the presence of a treatment gap was associated with a higher risk of an adverse event (HR 1.35, 95% CI 1.02 to 1.82). Conclusions Among contemporary, symptomatic patients with suspected CAD, significant gaps exist in preventive care and lifestyle practices, and high-risk patients sometimes had larger gaps. Differences by sex, age, race/ethnicity, socioeconomic status and geography are modest but contribute to disparities and have

    The association of an exaggerated systolic blood pressure increase with exercise (EBPIE) with cardiovascular events remains controversial. Our aim was to determine the possible association of an EBPIE with survival and risk of serious cardiac events in patients with hypertension and known or suspected coronary artery disease (CAD). This is a retrospective observational study based on a sample of 5226 patients with a history of arterial hypertension and known or suspected CAD referred for exercise echocardiography. The EBPIE was defined as an increase in systolic blood pressure with exercise greater than or equal to the 95th percentile of this population (80mmHg). The end points were all-cause mortality, cardiac death and myocardial infarction (MI). During a mean follow-up of 4.7 years, there were 978 deaths (including 371 cardiac) and 798 MI. Annual rates of all-cause mortality, cardiac mortality and MI were 2.73, 0.83 and 2.63% in patients with EBPIE and 4.4, 1.58 and 3.98% in those without EBPIE (P<.001, P=.012, and P=.014, respectively). After multivariate analysis, an EBPIE remained independently associated with a lower risk of all-cause mortality (HR: 0.70, 95% CI: 0.52-0.95; P=.023) and MI (HR: 0.69, 95% CI: 0.50-0.95; P=.022) but was not significantly associated with cardiac mortality (HR: 0.72, 95% CI: 0.43-1.20; P=.2). EBPIE was associated with an increased likelihood of survival and lower rate of MI in hypertensive patients with known or suspected CAD. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

    Full Text Available Abstract Background Previous studies from the USA have shown that acute nuclear myocardial perfusion imaging (MPI in low risk emergency department (ED patients with suspected acute coronary syndrome (ACS can be of clinical value. The aim of this study was to evaluate the utility and hospital economics of acute MPI in Swedish ED patients with suspected ACS. Methods We included 40 patients (mean age 55 ± 2 years, 50% women who were admitted from the ED at Lund University Hospital for chest pain suspicious of ACS, and who had a normal or non-ischemic ECG and no previous myocardial infarction. All patients underwent MPI from the ED, and the results were analyzed only after patient discharge. The current diagnostic practice of admitting the included patients for observation and further evaluation was compared to a theoretical "MPI strategy", where patients with a normal MPI test would have been discharged home from the ED. Results Twenty-seven patients had normal MPI results, and none of them had ACS. MPI thus had a negative predictive value for ACS of 100%. With the MPI strategy, 2/3 of the patients would thus have been discharged from the ED, resulting in a reduction of total hospital cost by some 270 EUR and of bed occupancy by 0.8 days per investigated patient. Conclusion Our findings in a Swedish ED support the results of larger American trials that acute MPI has the potential to safely reduce the number of admissions and decrease overall costs for low-risk ED patients with suspected ACS.

    Full Text Available Introduction: In spite of its importance as an experimental model, the information on the left coronary artery in pigs is sparse. Objective: To determine the morphologic features of the left coronary artery in pigs. Methods: We evaluated 158 pig hearts. The left coronary artery was perfused with synthetic resin after their ostia had been catheterized. Diameters and courses of the vascular beds were measured with an electronic caliper (Mitutoyo(r. Results: The diameter of left coronary artery was 6.98 ± 1.56 mm and its length was 3.51±0.99 mm. It was found to end up by bifurcating itself into the anterior interventricular artery and the circumflex artery in 79% of the cases, and by trifurcating in 21% of the cases, with the presence of the diagonal artery. The anterior interventricular artery ended up at the apex in 79.7% of the cases, and the circumflex artery at the posterior aspect of the left ventricle in 64% of the case, this artery never reached the posterior interventricular sulcus. An anastomosis between the terminal branches of the anterior interventricular artery and the posterior interventricular artery was found in 7.6% of the specimens. The antero-superior branch of the anterior interventricular artery occurred in 89.9% of the hearts. A left marginal branch was observed in 87.9% of the cases with a diameter of 2.25±0.55 mm. Conclusion: Compared with humans, pigs have shorter left coronary artery trunks and branches; even the circumflex artery never reaches the posterior interventricular sulcus. Our findings are useful for the design of experimental hemodynamic and procedural models.

    Cardiovascular diseases are the leading cause of death in Latin America, with ischemic heart disease as the principal cause in most countries. Risk factors for cardiovascular disease are highly prevalent in the region, but there are international variations in the pattern and level of risk factors. Overweight and obesity are increasing. In the 2012 Mexican National Survey, overweight or obesity was found in 64.9% of men and 73% of women, and they were strongly associated with sedentarism. The most characteristic dyslipidemia abnormality in the region is low high-density lipoprotein cholesterol, followed by elevated low-density lipoprotein cholesterol and increased levels of triglycerides. National diabetes mellitus prevalence ranges from 2.8% to 9.4% and tobacco smoking from 12.8% to 42%. According to the INTERHEART (A Study of Risk Factors for First Myocardial Infarction in 52 Countries and Over 27,000 Subjects) data for Latin America, the highest attributable risks for myocardial infarction were related to abdominal obesity, dyslipidemia, and smoking.

    The association between coronary heart disease (CHD) and dietary fiber intake is not consistent, especially for the subtypes of dietary fiber. The aim of our study was to conduct a meta-analysis of existing cohort published studies assessing the association between dietary fiber intake and risk of CHD, and quantitatively estimating their dose-response relationships. We searched PubMed and EMBASE before May 2013. Random-effect model was used to calculate the pool relative risk (RRs) for the incidence and mortality of CHD. Dose-response, subgroup analyses based on fiber subtypes, heterogeneity and publication bias were also carried out. Eighteen studies involving 672,408 individuals were finally included in the present study. The pooled-adjusted RRs of coronary heart disease for the highest versus lowest category of fiber intake were 0.93 (95% confidence interval (CI), 0.91-0.96, P fiber subtypes (cereal, fruit, and vegetable fiber), indicated that RRs were 0.92 (95% CI, 0.85-0.99, P = 0.032), 0.92 (95% CI, 0.86-0.98, P = 0.01), 0.95 (95% CI, 0.89-1.01, P = 0.098) respectively for all coronary event and 0.81 (95% CI, 0.72-0.92, P = 0.001), 0.68 (95% CI, 0.43-1.07, P = 0.094), 0.91 (95% CI, 0.74-1.12, P = 0.383) for mortality. In addition, a significant dose-response relationship was observed between fiber intake and the incidence and mortality of CHD (P dietary fiber is inversely associated with risk of coronary heart disease, especially for fiber from cereals and fruits. Besides, soluble and insoluble fibers have the similar effect. A significant dose-response relationship is also observed between fiber intake and CHD risk.

Coronary flow reserve (CFR is a physiological index of coronary microcirculation and is noninvasively measured by transthoracic Doppler echocardiography (TTDE. This study aimed to investigate the effects of RIC on CFR in healthy subjects and patients with HF, through the assessment by TTDE. Methods: Ten patients with HF with left ventricular ejection fraction of less than 40%, and ten healthy volunteers were enrolled in this study. RIC treatment was performed twice a day for 1 week. Our custom-made RIC device was programmed to automatically conduct 4 cycles of 5 minutes inflation and 5 minutes deflation of a blood pressure cuff to create intermittent arm ischemia. CFR measurements and laboratory tests were examined before, and after 1 week of RIC treatment. Results: One week of RIC treatment was well tolerated in both groups. RIC treatment increased CFR from 4.0±0.9 to 4.6±1.3 (mean ± standard deviation in healthy subjects (P=0.02, and from 1.9±0.4 to 2.3±0.7 in patients with HF (P=0.03, respectively. Systolic blood pressure in healthy subjects, and heart rate in HF patients decreased after RIC treatment (both P<0.01. Conclusion: This study demonstrated that a 1 week course of RIC treatment improved coronary microcirculation in healthy subjects and patients with HF associated with reduced left ventricular ejection fraction.

    Obesity and diabetes are strongly associated with metabolic and cardiovascular disorders including dyslipidemia, coronary artery disease, hypertension, and heart failure. Adipose tissue is identified as a complex endocrine organ, which by exerting a wide array of regulatory functions at the cellular, tissue and systemic levels can have profound effects on the cardiovascular system. Different terms including "epicardial," "pericardial," and "paracardial" have been used to describe adipose tissue deposits surrounding the heart. Epicardial adipose tissue (EAT) is a unique and multifaceted fat depot with local and systemic effects. The functional and anatomic proximity of EAT to the myocardium enables endocrine, paracrine, and vasocrine effects on the heart. EAT displays a large secretosome, which regulates physiological and pathophysiological processes in the heart. Perivascular adipose tissue (PVAT) secretes adipose-derived relaxing factor, which is a "cocktail" of cytokines, adipokines, microRNAs, and cellular mediators, with a potent effect on paracrine regulation of vascular tone, vascular smooth muscle cell proliferation, migration, atherosclerosis-susceptibility, and restenosis. Although there are various physiological functions of the EAT and PVAT, a phenotypic transformation can lead to a major pathogenic role in various cardiovascular diseases. The equilibrium between the physiological and pathophysiological properties of EAT is very delicate and susceptible to the influences of intrinsic and extrinsic factors. Various adipokines secreted from EAT and PVAT have a profound effect on the myocardium and coronary arteries; targeting these adipokines could be an important therapeutic approach to counteract cardiovascular disease.

    Surgical coronary revascularisation in children with congenital heart disease (CHD) is a rare event for which limited information is available. In this study, we review the indications and outcomes of surgical coronary revascularisation from the Pediatric Cardiac Care Consortium, a large US-based multicentre registry of interventions for CHD. This is a retrospective cohort study of children (coronary revascularisation between 1982 and 2011. In-hospital mortality and graft patency data were obtained from the registry. Long-term transplant-free survival through 2014 was achieved for patients with adequate identifiers via linkage with the US National Death Index and the Organ Procurement and Transplantation Network. Coronary revascularisation was accomplished by bypass grafting (n=72, median age 6.8 years, range 3 days-17.4 years) or other operations (n=65, median age 2.6 years, range 5 days-16.7 years) in 137 patients. Most revascularisations were related to the aortic root (61.3%) or coronary anomalies (27.7%), but 10.9% of them were unrelated to either of them. Twenty in-hospital deaths occurred, 70% of them after urgent 'rescue' revascularisation in association with another operation. Long-term outcomes were available by external linkage for 54 patients surviving to hospital discharge (median follow-up time 15.0 years, max follow-up 29.8 years) with a 15-year transplant-free survival of 91% (95% CI 83% to 99%). Surgical coronary revascularisation can be performed in children with CHD with acceptable immediate and long-term survival. Outcomes are dependent on indication, with the highest mortality in rescue procedures. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Objective. An appropriate psychological intervention to promote the level of mental health of patients with a coronary heart has a great importance. The existing investigation aimed to study the effectiveness of the behavioral-cognitive group therapy on depression, anxiety, and stress of patients with coronary heart disease. Methodology. The current study was quasi-experimental with a pretest-posttest that used a control group. Hence, 30 of the patients with coronary heart disease in Shahid Rajaee heart center in Tehran chose to use the convenience sampling method and were put in an experimental group and a control group. Both groups were pretested by using a demographic questionnaire, and scale of depression, anxiety, and stress DASS-42. Afterwards, the experimental group was trained for eight sessions of cognitive-behavioral club therapy and the control society gained no intervention. Later, both groups were post-tested, and the acquired information were analyzed by using inferential and descriptive statistical methods accompanied by SPSS 21 software. Findings. The results indicated that the cognitive-behavioral group therapy training significantly reduced depression, anxiety, and stress in patients with coronary heart disease. Conclusion. What should be understood from this study is that the cognitive-behavioral group therapy training had a great positive impact on the decrease of depression, anxiety, and tension in patients with coronary heart disease, since it had an economic cost and a great acceptability by the cases, especially when it was performed in a group.

    Analyses using conventional statistical methodologies have yielded conflicting results as to whether low-density lipoprotein cholesterol (LDL-C) or non-high-density lipoprotein cholesterol (non-HDL-C) or apolipoprotein B (apoB) is the best marker of the apoB-associated risk of coronary heart disease. The aim of this study was to determine the additional value of apoB beyond LDL-C or non-HDL-C as a predictor of coronary heart disease. For each patient from the Framingham Offspring Cohort aged 40-75 years (n = 2966), we calculated the extent to which the observed apoB differed from the expected apoB based on their LDL-C or non-HDL-C. We added this difference to a Cox model predicting new onset coronary heart disease over a maximum of 20 years adjusting for standard risk factors plus LDL-C or non-HDL. The difference between observed and expected apoB over LDL-C or non-HDL-C was highly prognostic of future coronary heart disease events: adjusted hazard ratios 1.26 (95% confidence interval: 1.15, 1.37) and 1.20 (1.11, 1.29), respectively, for each standard deviation increase beyond expected apoB levels. When this difference between observed and expected apoB was added to standard coronary heart disease prediction models including LDL-C or non-HDL-C, prediction improved significantly (likelihood ratio test p-values risk assessment of future coronary heart disease events over and beyond LDL-C or non-HDL-C, which is consistent with coronary risk being more closely related to the number of atherogenic apoB particles than to the mass of cholesterol within them. © The European Society of Cardiology 2015.

    Epidemiological studies suggest an association between sleep duration and risk of coronary heart disease, however, the results are controversial. We conducted this systematic review and meta-analysis to summarize the potential dose-response relationship between sleep duration and risk of coronary heart disease. The electronic reference databases (PubMed and Embase) were searched through January 2016 with selection criteria for relevant studies. Both semiparametric and parametric methods were used to calculate the pooled risk estimates. Seventeen articles with 22 independent reports involving 17,841 incident cases of coronary heart disease among 517,440 participants were included in our meta-analysis. A U-shaped relationship was detected between sleep duration and risk of coronary heart disease, with the lowest risk at 7-8h per day. Compared with 7h sleep duration per day, the combined relative risk of coronary heart disease were 1.11 (95% CI=1.05-1.16) for an reduction of 1h and 1.07 (95% CI=1.00-1.15) for an increment of 1h. And the results almost did not change in the subgroup analysis of gender and fatal cases. Exclusion of any single study did not alter the combined relative risk. In addition, visual inspection of funnel plots, Begg's and Egger's tests failed to identify publication bias. Both short and long sleep durations are significantly associated with increased risk of coronary heart disease. Compared with 7h sleep duration per day, the risk of coronary heart disease increases 11% for an hour decrease and increases 7% for an hour increase. Copyright © 2016 Elsevier Ireland Ltd.

    Heart disease remains the leading cause of death in the United States despite decades of advancement in its diagnosis and treatment. Due to the limitations of traditional risk stratification for heart disease, evaluation of the retinal vasculature has been proposed as an easily and safely measured adjunct to commonly used screening methods. In this article we provide a comprehensive review of the literature concerning the relationships between retinal microvascular abnormalities and coronary heart disease. We outline details of the most recent large epidemiological studies and discuss their potential implications for clinical practice. Finally, we propose a change to the current guidelines regarding the screening of “low risk” women, a group that is often failed by traditional evaluation algorithms. PMID:20362758

    The Middle East and North Africa has witnessed a dramatic transformation over the last 30 years caused by rapid urbanization and modernization and significant changes to diet and lifestyle. This review attempts to highlight recent data in regards to ischemic heart disease and its risk factors from the region. Ischemic heart disease is now the leading cause of death in the region. Age at presentation with myocardial infarction and acute coronary syndrome appears to be significantly younger than global averages. Increased rates of all major risk factors including diabetes, hypertension, hyperlipidemia, smoking, obesity, and sedentary lifestyle have been noted. Specifically, significant changes to dietary habits and growing epidemic of use of alternative tobacco products are noted. This review article highlights the growing epidemic of ischemic heart disease in the region led by dramatic increases in incidence of its risk factors. This epidemic will require a multipronged approach to address the varied issues and mitigate the growing prevalence of the disease.

  3. X-ray intravital microscopy for functional imaging in rat hearts using synchrotron radiation coronary microangiography

    2013-03-01

    An X-ray intravital microscopy technique was developed to enable in vivo visualization of the coronary, cerebral, and pulmonary arteries in rats without exposure of organs and with spatial resolution in the micrometer range and temporal resolution in the millisecond range. We have refined the system continually in terms of the spatial resolution and exposure time. X-rays transmitted through an object are detected by an X-ray direct-conversion type detector, which incorporates an X-ray SATICON pickup tube. The spatial resolution has been improved to 6 μm, yielding sharp images of small arteries. The exposure time has been shortened to around 2 ms using a new rotating-disk X-ray shutter, enabling imaging of beating rat hearts. Quantitative evaluations of the X-ray intravital microscopy technique were extracted from measurements of the smallest-detectable vessel size and detection of the vessel function. The smallest-diameter vessel viewed for measurements is determined primarily by the concentration of iodinated contrast material. The iodine concentration depends on the injection technique. We used ex vivo rat hearts under Langendorff perfusion for accurate evaluation. After the contrast agent is injected into the origin of the aorta in an isolated perfused rat heart, the contrast agent is delivered directly into the coronary arteries with minimum dilution. The vascular internal diameter response of coronary arterial circulation is analyzed to evaluate the vessel function. Small blood vessels of more than about 50 μm diameters were visualized clearly at heart rates of around 300 beats/min. Vasodilation compared to the control was observed quantitatively using drug manipulation. Furthermore, the apparent increase in the number of small vessels with diameters of less than about 50 μm was observed after the vasoactive agents increased the diameters of invisible small blood vessels to visible sizes. This technique is expected to offer the potential for direct

    Full Text Available Aims and Objectives: We evaluated the incidence and implications of coronary artery disease (CAD in patients above 40 years presenting for valve surgery. Materials and Methods: Between January 2009 and December 2010, coronary angiography (CAG was performed in all such patients ( n = 140. Results: Coronaries were normal in 119 (Group I, and diseased in 21 (Group II. In Group II, 11 patients were 61 years. In 8 of these, only valve replacement was performed. Coronary artery bypass grafting (CABG and aortic valve replacement was performed in 10, CABG and mitral valve replacement in 2 and CABG with mitral and aortic valve replacement in one. The number of vessels grafted in these 13 patients was 1.54 ± 0.66. Hypertension and diabetes were significant ( P < 0.05 in this group. The mortality was significant in Group II (11 vs. 6, P < 0.05. Six patients died in Group II, 5 had severe aortic stenosis and severe left ventricular hypertrophy; the sixth patient had severe mitral stenosis and was in CHF. The predominant cause of death was congestive heart failure (CHF. Conclusions: Fifteen percentage of these patients had CAD. CAG should be performed routinely in these patients while presenting for valve surgery. Combined CABG and valve replacement carries high mortality (28.5%, especially in patients with aortic stenosis. The study suggests that the cardio-protective measures should be applied more rigorously in this subset of patients.

    To estimate the costs and effect of implementing the National Service Framework for Coronary Heart Disease (CHD) in the UK. Decision trees were built on the results from randomised controlled trials on improving coronary revascularisation. All costs were presented in UK pounds (1997 values). Each year 6600 new patients with CHD are expected to require revascularisation in the UK. The new patients would be equally divided into those undergoing coronary artery bypass grafting (CABG) and those undergoing a percutaneous coronary intervention (PCI) i.e., percutaneous transluminal angioplasty (PCTA). PTCA could be administered with or without abciximab (a glycoprotein IIb/IIIa receptor antagonist), stent, or stent plus abciximab (stent+). CABG/stent alone has an incremental cost of more than 115,489 pounds per additional quality-adjusted life-year (QALY) gained compared with CABG/ PTCA+. This high incremental cost is not attractive because if CABG/ stent would be added to abciximab (CABG/stent+) its incremental cost-effectiveness ratio would be 2529 pounds per extra QALY compared with CABG/stent. Therefore, the debate should not be limited to the issue of stents but it should focus on the need for administering abciximab in addition to stent. The 5-year direct costs of implementing such a strategy in the UK is expected to be 50.6 million pounds (1997 values). Abciximab and probably any glycoprotein IIb/IIIa receptor antagonists should be added to any PCI, especially if stents are used.

    Cell-sheet transplantation induces angiogenesis for chronic myocardial infarction (MI), though insufficient capillary maturation and paucity of arteriogenesis may limit its therapeutic effects. Omentum has been used clinically to promote revascularization and healing of ischemic tissues. We hypothesized that cell-sheet transplantation covered with an omentum-flap would effectively establish mature blood vessels and improve coronary microcirculation physiology, enhancing the therapeutic effects of cell-sheet therapy. Rats were divided into four groups after coronary ligation; skeletal myoblast cell-sheet plus omentum-flap (combined), cell-sheet only, omentum-flap only, and sham operation. At 4 weeks after the treatment, the combined group showed attenuated cardiac hypertrophy and fibrosis, and a greater amount of functionally (CD31(+)/lectin(+)) and structurally (CD31(+)/α-SMA(+)) mature blood vessels, along with myocardial upregulation of relevant genes. Synchrotron-based microangiography revealed that the combined procedure increased vascularization in resistance arterial vessels with better dilatory responses to endothelium-dependent agents. Serial (13)N-ammonia PET showed better global coronary flow reserve in the combined group, mainly attributed to improvement in the basal left ventricle. Consequently, the combined group had sustained improvements in cardiac function parameters and better functional capacity. Cell-sheet transplantation with an omentum-flap better promoted arteriogenesis and improved coronary microcirculation physiology in ischemic myocardium, leading to potent functional recovery in the failing heart.

    The relationship between alcohol consumption and coronary heart disease (CHD) in various epidemiologic study designs is consistent, showing protection at alcohol consumption levels. Studies of potential mediators of the effects of alcohol on CHD show beneficial effects on HDL cholesterol and some coagulation factors, but, at higher levels of consumption, adverse effects on blood pressure, arrhythmias, and the myocardium. Statistical modeling of pathways for alcohol's effect on coronary disease is consistent with a protective pathway via elevated HDL cholesterol and an adverse pathway through elevated blood pressure. Maximum benefit for CHD appears to be reached at only one drink daily. Given that alcohol is an intoxicating and potentially addictive substance with a high abuse potential, and given the high morbidity and mortality associated with heavier drinking, public health recommendations to consume alcohol are contraindicated.

    OBJECTIVE: To explore how patients at risk of coronary heart disease (CHD) portray candidates for CHD. DESIGN: Qualitative interview study. SETTING: Norway. SUBJECTS: A total of 20 men and 20 women diagnosed with heterozygous familial hypercholesterolemia (FH) recruited through a lipid clinic. MAIN...... OUTCOME MEASURES: Participants' beliefs concerning persons who are considered candidates for CHD. RESULTS: Some participants believed that CHD could happen to anyone, while the majority conveyed detailed notions of persons they considered to be likely victims of CHD. Participants often portrayed...... the coronary candidate as someone who was different from themselves. Among those who mentioned gender, all presented the candidate as a man. Some women said that they had to reconcile themselves to being at risk of CHD, since they at first had conceived CHD as a man's disease. While some participants...

    To investigate this association between ABO blood groups and coronary heart disease (CHD) in the Chinese Guangxi Zhuang population. From August 2010 to April 2013, we performed a case-control study in a Chinese Zhuang population, which included 1 024 CHD cases and 1 024 age and gender-matched non-CHD controls. The ABO blood groups and biological variables were measured by standard laboratory procedures. The Gensini score was used to evaluate the severity of coronary artery stenosis. Compared to non-CHD control group, CHD group had higher levels of fasting blood glucose ((6.71 ± 6.72) mmol/L vs. (4.98 ± 1.55) mmol/L, P population. Compared with group O, the group B individuals had a higher risk of CHD (OR = 2.33, 95% CI 1.88-2.90, P population.

    To investigate and quantify the potential dose-response association between egg consumption and risk of coronary heart disease and stroke. Dose-response meta-analysis of prospective cohort studies. PubMed and Embase prior to June 2012 and references of relevant original papers and review articles. Prospective cohort studies with relative risks and 95% confidence intervals of coronary heart disease or stroke for three or more categories of egg consumption. Eight articles with 17 reports (nine for coronary heart disease, eight for stroke) were eligible for inclusion in the meta-analysis (3,081,269 person years and 5847 incident cases for coronary heart disease, and 4,148,095 person years and 7579 incident cases for stroke). No evidence of a curve linear association was seen between egg consumption and risk of coronary heart disease or stroke (P=0.67 and P=0.27 for non-linearity, respectively). The summary relative risk of coronary heart disease for an increase of one egg consumed per day was 0.99 (95% confidence interval 0.85 to 1.15; P=0.88 for linear trend) without heterogeneity among studies (P=0.97, I(2)=0%). For stroke, the combined relative risk for an increase of one egg consumed per day was 0.91 (0.81 to 1.02; P=0.10 for linear trend) without heterogeneity among studies (P=0.46, I(2)=0%). In a subgroup analysis of diabetic populations, the relative risk of coronary heart disease comparing the highest with the lowest egg consumption was 1.54 (1.14 to 2.09; P=0.01). In addition, people with higher egg consumption had a 25% (0.57 to 0.99; P=0.04) lower risk of developing hemorrhagic stroke. Higher consumption of eggs (up to one egg per day) is not associated with increased risk of coronary heart disease or stroke. The increased risk of coronary heart disease among diabetic patients and reduced risk of hemorrhagic stroke associated with higher egg consumption in subgroup analyses warrant further studies.

    Although HDL cholesterol concentrations are strongly and inversely associated with risk of coronary heart disease, interventions that raise HDL cholesterol do not reduce risk of coronary heart disease. HDL cholesterol efflux capacity-a prototypical measure of HDL function-has been associated with coronary heart disease after adjusting for HDL cholesterol, but its effect on incident coronary heart disease risk is uncertain. We measured cholesterol efflux capacity and assessed its relation with vascular risk factors and incident coronary heart disease events in a nested case-control sample from the prospective EPIC-Norfolk study of 25 639 individuals aged 40-79 years, assessed in 1993-97 and followed up to 2009. We quantified cholesterol efflux capacity in 1745 patients with incident coronary heart disease and 1749 control participants free of any cardiovascular disorders by use of a validated ex-vivo radiotracer assay that involved incubation of cholesterol-labelled J774 macrophages with apoB-depleted serum from study participants. Cholesterol efflux capacity was positively correlated with HDL cholesterol concentration (r=0·40; pcholesterol efflux capacity was significantly and inversely associated with incident coronary heart disease events, independent of age, sex, diabetes, hypertension, smoking and alcohol use, waist:hip ratio, BMI, LDL cholesterol concentration, log-triglycerides, and HDL cholesterol or apoA-I concentrations (odds ratio 0·64, 95% CI 0·51-0·80). After a similar multivariable adjustment the risk of incident coronary heart disease was 0·80 (95% CI 0·70-0·90) for a per-SD change in cholesterol efflux capacity. HDL cholesterol efflux capacity might provide an alternative mechanism for therapeutic modulation of the HDL pathway beyond HDL cholesterol concentration to help reduce risk of coronary heart disease.

    To determine if a disease management programme for patients with coronary heart disease and heart failure represents an efficient use of health services resources. We carried out an economic evaluation alongside a cluster randomised control trial of 1163 patients with coronary heart disease and chronic heart failure in 20 primary care practices in the United Kingdom. Practices were randomised to either a control group, where patients received standard general practice care, or an intervention group where patients had access to a specialist nurse-led disease management programme. We estimated costs in both groups for coronary heart disease-related resource use. The main outcome measure used in the economic evaluation was quality adjusted life years (QALY) measured using the EuroQol. The disease management programme was associated with an increase in the QALY measured of 0.03 per year and an increase in the total NHS costs of 425 pounds (540 euros), of this only 83 pounds was directly associated with the provision of the nurse clinics. The clinics generated additional QALY at an incremental cost of 13 pounds 158 per QALY compared to the control group. The use of a nurse-led disease management programme is associated with increased costs in other coronary heart disease-related services as well as for the costs of the clinics. They are also associated with improvements in health. Even in the short term these disease management programmes may represent a cost-effective service, as additional QALY are generated at an acceptable extra cost.

    Objectives: The purpose of our study was to determine the relationship between the predictive factors and systolic reconstruction (SR) as an optimal reconstruction window in patients with low heart rate (LHR; less than 65 bpm). Methods: 391 patients (262 male and 129 female, mean age; 67.1 {+-} 10.1 years of age) underwent coronary CTA without the additional administration of a beta-blocker. Affecting factors for SR were analyzed in age, gender, body weight (BW), diabetes mellitus (DM), coronary arterial disease (CAD), ejection fraction (EF), systolic and diastolic body pressure (BP) and heart rate variability (HRV) during coronary CTA. Results: In 29 (7.4%) of the 391 patients, SR was needed, but there was no apparent characteristic difference between the systolic and diastolic reconstruction groups in terms of gender, age, BW, DM, CAD and EF. In a multivariate analysis, the co-existence of DM [P < 0.05; OR, 0.27; 95% CI, 0.092-0.80], diastolic BP [P < 0.01; OR, 0.95; 95% CI, 0.92-0.98] and HRV [P < 0.01; OR, 0.98; 95% CI, 0.96-0.99] were found to be the factors for SR. In gender-related analysis, HRV was an important factor regardless of sex, but co-existence of DM affected especially for female and BP for male. Conclusion: Especially in the patients with LHR who had a medication of DM, high HRV or high BP, SR, in addition to DR, was needed to obtain high-quality coronary CTA images.

    Patients with chronic stable angina often have a state of sympathetic hyperactivity. It is considered associated with myocardial ischemia and disappears after ischemia elimination. The aim of this study was to investigate the changes in heart rate variability parameters, a noninvasive technique for the evaluation of the autonomic nervous system activity, after successful revascularization in these patients to evaluate this theory. The patients were enrolled among those who underwent successful percutaneous coronary intervention. Short-term heart rate variability analyses of all the patients were obtained, and time-domain indices (standard deviation of normal-to-normal intervals [SDNN], standard deviation of differences of successive R-R intervals [SDSD], root-mean square differences of successive R-R intervals [rMSSD], percentage of R-R intervals differing > 10 ms from the preceding one [PNN10], percentage of R-R intervals differing > 20 ms from the preceding one [PNN20], percentage of R-R intervals differing > 30 ms from the preceding one [PNN30], percentage of R-R intervals differing > 40 ms from the preceding one [PNN40], percentage of R-R intervals differing > 50 ms from the preceding one [PNN50], percentage of R-R intervals differing > 60 ms from the preceding one [PNN60], and percentage of R-R intervals differing > 70 ms from the preceding one [PNN70]) were analyzed. All the measurements were made before and after percutaneous coronary intervention. This study included 64 patients, comprising 27 men and 37 women at a mean age of 56.8 ± 9.1 years. There was a significant difference only between pre- and post-revascularization SDNN (27.5 ± 19.72 vs. 41 ± 41.4; p value = 0.013). The other parameters showed no significant differences after successful coronary intervention. Conclusion : Our data indicate that the increase in SDNN in patients with stable angina pectoris undergoing percutaneous coronary intervention seems to be prominent.

    Coronary heart disease preoperative diagnosis plays an important role in the treatment of vascular interventional surgery. Actually, most doctors are used to diagnosing the position of the vascular stenosis and then empirically estimating vascular stenosis by selective coronary angiography images instead of using mouse, keyboard and computer during preoperative diagnosis. The invasive diagnostic modality is short of intuitive and natural interaction and the results are not accurate enough. Aiming at above problems, the coronary heart disease preoperative gesture interactive diagnostic system based on Augmented Reality is proposed. The system uses Leap Motion Controller to capture hand gesture video sequences and extract the features which that are the position and orientation vector of the gesture motion trajectory and the change of the hand shape. The training planet is determined by K-means algorithm and then the effect of gesture training is improved by multi-features and multi-observation sequences for gesture training. The reusability of gesture is improved by establishing the state transition model. The algorithm efficiency is improved by gesture prejudgment which is used by threshold discriminating before recognition. The integrity of the trajectory is preserved and the gesture motion space is extended by employing space rotation transformation of gesture manipulation plane. Ultimately, the gesture recognition based on SRT-HMM is realized. The diagnosis and measurement of the vascular stenosis are intuitively and naturally realized by operating and measuring the coronary artery model with augmented reality and gesture interaction techniques. All of the gesture recognition experiments show the distinguish ability and generalization ability of the algorithm and gesture interaction experiments prove the availability and reliability of the system.

    Cannulation and clamping of a severely atherosclerotic ascending aorta during coronary artery bypass grafting (CABG) can lead to cerebral embolization of atheromatous debris and should therefore be avoided whenever possible. A variety of surgical techniques including performance of extraanatomical coronary bypass conduits has been described to solve this problem. We report on a preliminary series of four patients in whom the axillary artery was used as an inflow vessel for venous coronary artery bypass grafts which were performed on the beating heart in order to achieve an aortic no touch concept. The axillary artery was exposed between the pectoralis major muscle and the deltoid muscle via an infraclavicular incision. A saphenous vein graft of at least 40 cm in length was sutured to the axillary artery and then brought into the pericardial cavity following an intercostal and transpleural route. The graft was anastomosed to the target vessel using local coronary occlusion. The procedure was carried out via sternotomy in three patients who also received additional internal mammary artery in situ grafts for adequate coronary revascularization. In one high risk patient an isolated axillocoronary bypass was performed in a minimally invasive fashion via anterolateral minithoracotomy. The procedure was completed without major technical difficulties in all four patients. The mean graft length required was 33.2 +/- 1.6 cm, postoperative ultrasonic duplex scans of the axillocoronary grafts revealed a mean flow of 62.5 +/- 23.6 ml/min. No stroke or brachial plexus injury occurred. Three patients are in angina class I (Canadian Cardiovascular Society Classification), one patient is in class II postoperatively. After a mean follow-up of 11.5 +/- 6.6 months postoperatively all grafts remain patent. Axillocoronary bypass grafting can be easily performed for management of the untouchable ascending aorta.

    To assess the effect of systolic data acquisition for electrocardiography (ECG)-triggered high-pitch computed tomography (CT) on motion artefacts of coronary arteries in patients with high heart rates (HRs). Eighty consecutive patients (15 women, age 67 {+-} 14 years) with HR {>=}70 bpm underwent CT angiography of the thoracic aorta (CTA) on 128-slice dual-source CT in ECG-triggered high-pitch acquisition mode (pitch = 3.2) set at 60% (group A, n = 40) or 30% (group B, n = 40) of the RR interval. Two blinded readers graded coronary artery image quality on a three-point scale. Radiation doses were calculated. Inter-observer agreement in grading image quality of the 1,154 coronary segments was good ({kappa} = 0.62). HRs were similar in groups A and B (85 {+-} 13 bpm vs 85 {+-} 14 bpm, p not significant). Significantly fewer coronary segments with non-diagnostic image quality occurred (i.e. score 3) in group B than in group A [2.8% (16/579) vs 8.3% (48/575), p < 0.001]. Seventeen patients (42.5%) of group A and 12 patients (30.0%) of group B had at least one non-diagnostic segment. Effective radiation doses were 2.3 {+-} 0.3 mSv for chest CTA. A systolic acquisition window for high-pitch dual-source CTA in patients with high HRs ({>=}70 bpm) significantly improves coronary artery image quality at a low radiation dose. (orig.)

    We investigated associations of pre-clinical coronary heart disease (CHD), adolescence and adulthood CHD risk factors, and epicardial fat volume (EFV), which is thought to influence CHD pathology. EFV and coronary calcium scores were quantified using computed tomography imaging for 557 subjects from the Cardiovascular Risk in Young Finns Study in 2007. CHD risk marker levels were assessed repeatedly from 1980 to 2007. Carotid intima-media thickness (cIMT), carotid distensibility, and brachial flow-mediated dilatation were measured by vascular ultrasound in 2007. Increased EFV was cross-sectionally associated with male sex, increased waist circumference, body-mass index (BMI), cIMT, metabolic syndrome prevalence, levels of apolipoprotein B, total cholesterol, low-density lipoprotein cholesterol, triglycerides, C-reactive protein, blood pressure, insulin, and fasting glucose, as well as ever smoking, alcoholic intake, and lower high-density lipoprotein cholesterol (HDL-C), carotid distensibility and physical activity in adulthood. In BMI-adjusted analyses, only apolipoprotein B, ever smoking, alcohol intake and metabolic syndrome prevalence were independently associated with EFV. In adolescence, skinfold thickness, BMI, and insulin levels were higher and HDL-C lower with increasing EFV. Subjects in the lowest vs. highest quarter of EFV had consistently lower BMI across the early life-course. Associations of CHD risk markers with EFV were attenuated after multivariable adjustment. We found no evidence of increased EFV being independently associated with pre-clinical atherosclerosis. EFV was most strongly associated with BMI and waist circumference. Subjects with higher EFV had consistently higher BMI from age 12 suggesting that life-long exposure to higher BMI influences the development of EFV.
