Sample records for acute myocardial infarction

  1. Acute myocardial infarct imaging

    A brief review is presented of radiopharmaceuticals used for imaging acute myocardial infarction and instrumentation using the rectilinear scanner and the scintillation camera. Clinical experience indicates that myocardial imaging with /sup 99 m/Tc pyrophosphate is a useful adjunct to the electrocardiogram and serum enzyme activity in managing patients with myocardial infarction. The technique allows rapid diagnosis, accurate localization, and an estimate of the size of acute infarcts. It can also be used to document infarct extension and in association with myocardial perfusion imaging can help differentiate fresh from old myocardial infarction

    Heart disease is the leading cause of hospitalization and death in the United States among persons age 65 and older. Acute myocardial infarction (AMI), more commonly known as heart attack, accounted for more than 321,000 hospitalizations among Medicare beneficiaries in 2001. This report presents trends in AMI hospitalization, readmission, and mortality rates from 1992 through 2001 among Medicare fee-for-service beneficiaries across various demographic groups.

  3. Acute myocardial infarction.

    Rischpler, Christoph

    2016-09-01

    Inflammatory processes after myocardial infarction have gained major interest in recent cardiovascular research. It is believed that not only the degree of cell recruitment to the heart plays a pivotal role in the quality of wound healing after myocardial infarction, but also the balance between different types or even subtypes of cells. It is also this balance which is thought to control key processes in tissue repair, such as apoptosis and neoangiogenesis. In this paper, we aim to review imaging strategies (with a special focus on nuclear molecular imaging strategies) that target cells and processes involved in postischemic inflammation and that have a high potential to be translated into clinic or that are already being used and evaluated in humans.

  6. [Fibrinolysis in acute myocardial infarct].

    Bleifeld, W

    1987-10-24

    Fibrinolysis has opened up a new avenue in the treatment of acute myocardial infarction (AMI). In principle, the rate of reperfusion depends on the type of compound used, the mode of administration and the time between onset of symptoms and the beginning of treatment. With intracoronary streptokinase the reperfusion rate is of the order of 85%. Intravenous urokinase administered as a bolus results in a reopening rate of 50-60%; a similar rate of reperfusion is achieved with rt-PA as infusion, while i.v. streptokinase produces about 50% reopened coronary vessels. The final infarct size is decreased in 70% of patients if fibrinolysis is initiated within 2.5 hours after the onset of symptoms and followed by reopening of the occluded vessel. This results in a lowering of in-hospital mortality, which in various studies is of the order of 45-60%.- Bearing in mind the contraindications, fibrinolysis should be initiated within 3 hours. Hemodynamic improvement by a decrease of infarct size may also be achieved beyond 3 hours in large anterior myocardial infarctions and in posterior infarctions with cardiogenic shock. Early initiation of thrombolysis is of major importance in improving left ventricular function and lowering mortality following acute myocardial infarction. Therefore, prehospital thrombolytic therapy should be considered. - In the postinfarction phase coronary angiography is indicated in patients with angina at rest, stable angina of ECG signs of ischemia. In this situation transfer to a specialized cardiology division for possible percutaneous transluminal angioplasty is indicated. - Reocclusion after successful thrombolysis occurs in 20-30%, and it is therefore important to avoid reinfarction to improve the long term prognosis after AMI.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3321420

    2008-01-01

    Patients with abrupt onset of chest pain, ischemic ECG abnormalities and elevated levels of cardiac markers could be given a diagnosis of acute myocardial infarction. However, some other diseases should be taken into consideration in this clinical setting when coronary arteries are proven to be normal. Here we report a case of acute myopericarditis with clinical presentation of myocardial infarction and normal coronary anatomy. The Herpes Simplex Virus Ⅱ was considered as the organism causing myopericarditis and the patient was recovered by the treatment with valacicloavir. A precise diagnosis is a prerequisite of successful treatment and favorable prognosis.

  15. Perfusion scintigraphy in acute myocardial infarction

    The Tc-99m sestamibi perfusion SPECT scintigraphy in acute myocardial infarction is a feasible method to assess the size of area at risk and the residual blood flow to this area as the most important determinants of final infarct size without any delay in treatment. In combination with a follow-up study final infarct size as well as myocardial salvage can be quantified. Clinical indications for the use of Tc-99m sestamibi scintigraphy are the noninvasive identification of arterial occlusion in patients suspected to acute myocardial infarction without electrocardiographic ST-elevation and the assessment of reperfusion success. In clinical trials Tc-99m sestamibi scintigraphy has proven to be a useful method to assess the impact of varying reperfusion therapies. The present review article discusses the indication, the study protocol, the interpretation of results and the clinical and scientifically importance of this method. (orig.)

  20. Thrombolytic therapy in acute myocardial infarction.

    Woo, K S; White, H D

    1994-07-01

    Thrombolytic therapy has revolutionized the treatment of acute myocardial infarction by reducing mortality and preserving left ventricular function. It is relatively safe and cost-effective. However, it is currently underused in most countries. Patients in whom thrombolysis is indicated include those with ST elevation on the electrocardiogram or bundle branch block pattern who present within 12 hours of myocardial infarction; the indications should be widened to include the elderly, patients who have undergone nontraumatic cardiopulmonary resuscitation, and women during menstruation. The risk-benefit ratio should be assessed for the individual patient. Prehospital thrombolytic treatment has been shown to be feasible with the support of well-trained staff and resuscitation equipment, and may be cost-effective in communities with time delays before hospitalization greater than 1 hour. The most important strategy is to shorten the "door to needle" time in hospital. The importance of full infarct-related artery flow (Thrombolysis in Myocardial Infarction [TIMI] grade 3 flow) for preservation of ventricular function and survival has been documented in the second Thrombolysis Trial of Eminase in Acute Myocardial Infarction (TEAM 2) and the Global Utilization of Streptokinase and t-PA for Occluded Coronary Arteries (GUSTO) studies. Aspirin and heparin are beneficial adjunctive regimens to thrombolytic therapy but optimal epicardial reperfusion is achieved in only about half of patients. Improved thrombolytic, adjunctive antiplatelet, and antithrombotic regimens are required to achieve early full reperfusion, which is crucial to improve survival and quality of life. PMID:7919592

  1. [Prehospital thrombolytic therapy in acute myocardial infarction].

    Carlsson, J; Schuster, H P; Tebbe, U

    1997-10-01

    The extent of myocardial damage occurring during acute myocardial infarction is time dependent, and there is abundant evidence from most clinical trials that mortality reduction is greatest in patients treated early with thrombolytic agents, although beneficial effects have been shown with treatment initiated up to 12 h after onset of symptoms. All studies on prehospital thrombolysis have conclusively shown the practicability and safety of patient selection and administration of the thrombolytic agent. The accuracy of diagnosis in the prehospital setting was comparable to trials of in-hospital thrombolysis, e.g., in the Myocardial Infarction Triage and Intervention Project (MITI) 98% of the patients enrolled had subsequent evidence of acute myocardial infarction. With regard to time savings, all randomized studies showed positive results. The smallest time gain was observed in the MITI trial: prehospital-treated patients received thrombolytic therapy an average of 33 min earlier than those treated in hospital. In the European Myocardial Infarction Project (EMIP) the difference in time between prehospital and hospital treatment was a median of 55 min. However, none of these trials was able to show a significant short-term mortality difference between the two groups. Only a meta analysis of five randomized studies with a combined median time gain of about 60 min showed a significant 17% reduction in short-term mortality for patients who received thrombolytic therapy in the prehospital phase. In the Grampian Region Early Anistreplase Trial (GREAT), a study performed in a more rural area than other studies, the time gain by prehospital initiation of thrombolysis was a median of 130 min. GREAT was the only study to date reporting a significant mortality benefit for prehospital-treated patients after 3 months and 1 year. In conclusion, prehospital thrombolysis is feasible and safe. Patients with acute myocardial infarction can be correctly identified and treated with

    2013-09-01

    This study aimed to describe the family experiences post-infarction. Qualitative, descriptive and exploratory research, carried out with six families of post-infarction patients. Data collection was conducted in families' homes, in the period of February to May of 2012, through observation and interviews with the family. The software Atlas Ti 6.2 was used to code the interviews and the data were explored with thematic analysis. Two categories emerged "Difficult times": immediate consequence of acute myocardial infarction for the families; and "We reeducate ourselves--we can adapt ourselves": current experience of families. The immediate post-infarction experience is permeated by several feelings, with the need for families to adapt to fit into the needs. The current experience shows changes in families due to the disease. The family is the main responsible for the care giving, although Nursing should exchange and share knowledge. PMID:24344600

    2016-01-01

    An individual experiencing dyspnoea or syncope at high altitude is commonly diagnosed to have high-altitude pulmonary edema or cerebral edema. Acute myocardial infarction (AMI) is generally not considered in the differential diagnosis. There have been very rare cases of AMI reported only from Mount Everest. We report a case of painless ST segment elevation myocardial infarction (STEMI) that occurred while climbing Mount Kilimanjaro. A 51-year-old man suffered dyspnoea and loss of consciousness near the mountain peak, at about 5600 m. At a nearby hospital, he was treated as a case of high-altitude pulmonary edema. ECG was not obtained. Two days after the incident, he presented to our institution with continued symptoms of dyspnoea, light-headedness and weakness, but no pain. He was found to have inferior wall and right ventricular STEMI complicated by complete heart block. He was successfully managed with coronary angioplasty, with good recovery. PMID:26989121

  12. Systemic inflammatory response following acute myocardial infarction

    Lu FANG; Xiao-Lei Moore; Anthony M Dart; Le-Min WANG

    2015-01-01

    Acute cardiomyocyte necrosis in the infarcted heart generates damage-associated molecular patterns, activating complement and toll-like receptor/interleukin-1 signaling, and triggering an intense inflammatory response. Inflammasomes also recognize danger signals and mediate sterile inflammatory response following acute myocardial infarction (AMI). Inflammatory response serves to repair the heart, but excessive inflammation leads to adverse left ventricular remodeling and heart failure. In addition to local inflammation, profound systemic inflammation response has been documented in patients with AMI, which includes elevation of circulating inflammatory cytokines, chemokines and cell adhesion molecules, and activation of peripheral leukocytes and platelets. The excessive inflammatory response could be caused by a deregulated immune system. AMI is also associated with bone marrow activation and spleen monocytopoiesis, which sustains a continuous supply of monocytes at the site of inflammation. Accumulating evidence has shown that systemic inflammation aggravates atherosclerosis and markers for systemic inflammation are predictors of adverse clinical outcomes (such as death, recurrent myocardial in-farction, and heart failure) in patients with AMI.

  15. MR imaging of acute myocardial infarction

    This paper reports on superparamagnetic iron oxide particles (AMI-25) evaluated in comparison with paramagnetic Gd-DOTA for the MR evaluation of acute myocardial infarct size. Twelve openchest dogs underwent 2 hours of LAD occlusion followed by 6 hours of reperfusion. AMI-25 and Gd-DOTA were intravenously injected 1 hour and 10 minutes before euthanasia, respectively, in two groups of six dogs. Gradient-echo and T1- and T2-weighted spin-echo images were obtained in six AMI-25-injected excised hearts, and T1- and T2-weighted images in six Gd-DOTA injected excised hearts. Infarct size was evaluated by planimetry of each 8-mm-thick transverse slice after ex vivo double staining and correlated with the planimetry of each 8-mm-thick transverse MR section

  16. Computational modeling of acute myocardial infarction.

    Sáez, P; Kuhl, E

    2016-01-01

    Myocardial infarction, commonly known as heart attack, is caused by reduced blood supply and damages the heart muscle because of a lack of oxygen. Myocardial infarction initiates a cascade of biochemical and mechanical events. In the early stages, cardiomyocytes death, wall thinning, collagen degradation, and ventricular dilation are the immediate consequences of myocardial infarction. In the later stages, collagenous scar formation in the infarcted zone and hypertrophy of the non-infarcted zone are auto-regulatory mechanisms to partly correct for these events. Here we propose a computational model for the short-term adaptation after myocardial infarction using the continuum theory of multiplicative growth. Our model captures the effects of cell death initiating wall thinning, and collagen degradation initiating ventricular dilation. Our simulations agree well with clinical observations in early myocardial infarction. They represent a first step toward simulating the progression of myocardial infarction with the ultimate goal to predict the propensity toward heart failure as a function of infarct intensity, location, and size.

  18. Thrombolysis for acute myocardial infarction: drug review.

    Cundiff, David K

    2002-01-01

    The proof of efficacy of thrombolysis for acute myocardial infarction (AMI) depends on 9 randomized placebo-controlled trials totaling 58,511 patients. The meta-analysis of these trials showed an overall survival advantage of about 2% (11.5% vs 9.6%) in favor of thrombolysis. Iatrogenic deaths from thrombolysis complications occur in about 1% of AMI patients. Timely opening of the infarct-related artery (IRA) allowing myocardial reperfusion has been proposed to explain any survival advantage seen with thrombolysis ("open-artery hypothesis"). Angiographic data does not support the open-artery hypothesis as the mechanism of any benefit of thrombolysis. The "early hazard" (ie, increased mortality in the first 12 hours after thrombolysis) also suggests that the supposed survival benefit is due to something other than early reperfusion. The variable use of aspirin in the meta-analysis trials may have confounded the results and conclusions. In the 4 studies of the meta-analysis in which aspirin was used routinely (n = 21,144), the survival benefit was not statistically significant (P =.14). Lack of blinding in some studies and other methodologic problems may also call the conclusions of the meta-analysis into question. AMI registry reports comparing patients with and without thrombolysis have not borne out a significant survival advantage with thrombolysis. The National Registry of Myocardial Infarction (NRMI) registry data suggest that a significant number of AMI patients may be inappropriately receiving thrombolytics. An independent analysis of the NRMI mortality data adjusted for age and other risk factors would help determine whether thrombolysis for AMI improves survival. PMID:11965203

  2. Cancer risk of patients discharged with acute myocardial infarct

    Dreyer, L; Olsen, J H

    1998-01-01

    We studied whether common shared environmental or behavioral risk factors, other than tobacco smoking, underlie both atherosclerotic diseases and cancer. We identified a group of 96,891 one-year survivors of acute myocardial infarct through the Danish Hospital Discharge Register between 1977 and...... acute myocardial infarct patients were similar to those of the general population, as were the rates for hormone-related cancers, including endometrial and postmenopausal breast cancers. We found a moderate increase in the risk for tobacco-related cancers, which was strongest for patients with early...... onset of acute myocardial infarct and for female patients. Overall, there do not seem to be major shared environmental or behavioral risk factors for acute myocardial infarct and cancers, except for smoking, and there seems to be no common inherited susceptibility to the development of these diseases....

    Hsi, W L; Lai, J S

    1996-01-01

    Although maximal oxygen consumption (VO2max) and oxygen consumption at anaerobic threshold (VO2AT) were used to measure cardiac function, the clinical significance in acute myocardial infarction (MI) has not been reported. The purpose of this study was to compare VO2max and VO2AT between post-MI patients and healthy men and to correlate the parameters to other clinical measures. Forty-three active healthy men, 44 sedentary healthy men, and 43 post-MI patients were studied using incremental cycle exercise test. Their work rates, oxygen consumption, heart rates, oxygen pulses, ventilation, and other parameters at VO2max and VO2AT were determined with spirometer, gas concentration analyzer, and electrocardiograph. Anaerobic threshold was determined by analyzing the ventilatory parameters. Most of the exercise test parameters at VO2max were greatest in the active men, intermediate in the sedentary men, and least in the post-MI patients (P pressure products of the active men and sedentary men were not significantly different from each other and were greater than those of the post-MI patients (P < 0.01). In the post-MI patients, VO2max was inversely correlated to the peak serum level of creatine phosphokinase MB isoenzyme (P < 0.01) and associated with extensive infarction (P < 0.05). Most of the parameters at VO2AT were greater in the active men than in the sedentary men (P < 0.01) but not significantly different between the sedentary men and post-MI patients. In the post-MI patients, VO2AT was significantly correlated to left ventricular ejection fraction (P < 0.01) and associated with heart failure (P < 0.05). The results revealed that VO2max and VO2AT had different clinical significance in post-MI patients; VO2max was related to the infarct size, and VO2AT was related to the pumping function of heart.

  7. The importance of early patency after acute myocardial infarction.

    Grover, A; Rihal, C S

    1995-07-01

    The importance of achieving rapid patency of the infarct-related artery during acute myocardial infarction has become well recognized. Early, sustained patency of the infarct-related vessel correlates with improved left ventricular function, better in-hospital outcomes, and lower mortality. Various strategies designed to improve early patency, including "prehospital" thrombolysis, use of an accelerated recombinant tissue plasminogen activator regimen, and immediate angioplasty have been studied. This paper reviews the importance of achieving early patency, the various strategies employed, and the evidence for their efficacy. Future directions in treatment of acute myocardial infarction are touched upon briefly. PMID:7549077

  8. Acute myocardial infarction in a young patient

    Myocardial infarction (MI) is considered to be the disease of the fifth and sixth decade as seen in the West but an earlier age incidence is not infrequently encountered in the South Asian population. However, occurrence of MI in the teen-age still remains a rare happening. We are reporting a case of a teenager, who suffered a myocardial infarction with cardiogenic shock and pulmonary edema on two separate occasions with ECG and biochemical evidence of myocardial infarction. An exercise stress test done in between the two episodes was negative at a workload of 13.5 METs. A coronary angiogram done after the second event revealed normal coronary arteries and a preserved left ventricular systolic and segmental function. Except for low HDL (high density lipoprotein) and mildly raised homocysteine levels, the patient did not have other conventional or novel risk factors for coronary artery disease. (author)

  10. Copeptin Testing in Acute Myocardial Infarction: Ready for Routine Use?

    Sebastian Johannes Reinstadler

    2015-01-01

    Full Text Available Suspected acute myocardial infarction is one of the leading causes of admission to emergency departments. In the last decade, biomarkers revolutionized the management of patients with suspected acute coronary syndromes. Besides their pivotal assistance in timely diagnosis, biomarkers provide additional information for risk stratification. Cardiac troponins I and T are the most sensitive and specific markers of acute myocardial injury. Nonetheless, in order to overcome the remaining limitations of these markers, novel candidate biomarkers sensitive to early stage of disease are being extensively investigated. Among them, copeptin, a stable peptide derived from the precursor of vasopressin, emerged as a promising biomarker for the evaluation of suspected acute myocardial infarction. In this review, we summarize the currently available evidence for the usefulness of copeptin in the diagnosis and risk stratification of patients with suspected acute myocardial infarction in comparison with routine biomarkers.

    A 24-year-old healthy man consulted to our center because of typical on-and-off chest-pain and an electrocardiogram showing ST-segment elevation in inferior leads. An urgent coronary angiography showed angiographically normal coronary arteries. Cardiovascular magnetic resonance imaging confirmed acute myocarditis. Although acute myocarditis triggering coronary spasm is an uncommon association, it is important to recognize it, particularly for the management for those patients presenting with ST-segment elevation and suspect myocardial infarction and angiographically normal coronary arteries. The present report highlights the role of cardiovascular magnetic resonance imaging to identify acute myocarditis as the underlying cause.

    The aim of this investigation was to determine whether H. pylori infection is an independent risk factor for acute myocardial infarction (AMI), determine is there a link between H. pylori infection and severity of disease. In this prospective, single centre study, were enrolled 100 patients with AMI and control group was consisted 93 healthy individuals. The results of this study showed no difference between H. pylori seropositivity distribution in the investigate and control group (29 vs. 26 %) and there was no significant difference on the severity of the disease. There was significant association in the patients with three and more risk factors, where the patients with lower blood pressure (124.4/77.4 vs. 145.9/87.7 mmHg) and better controlled diabetes (HbA1c 6.1% vs. 6.9%) had greater risk for AMI if they are H. pylori seropositive. The large multicentric trials would be needed to define a precise role of H. pylori infection on the developement of AMI. PMID:22053556

    Full Text Available A retrospective study were performed in patients with acute myocardial infarction (AMI that hospitalized in ICCU Cipto Mangunkusumo hospital, Jakarta during the period of January 1994 until Decmber 1999. There were 513 patients hospitalized with MCI, 227 patients (44.2% were classified as elderly, and 35.2% of them were female. Most of the elderly AMI patients reported typical chest pain just like their younger counterparts. Elderly AMI patients tend to come later to the hospital, and more Q-wave myocardial infarction were identified compared to non- Q-wave myocardial infarction. Risk factors of diabetes mellitus and hypertension were more common among the elderly. The prevalence of atrial fibrillation and the mortality rate were higher among elderly AMI patients.

  15. The tole of ischemic preconditioning in acute myocardial infarction

    Ristić Anđelka

    2005-01-01

    Full Text Available Introduction Ischemic preconditioning is a phenomenon in which brief episodes of ischemia and reperfusion increase myocardial tolerance and substantially reduce the infarction size. Case report Two patients with acute left anterior descending artery occlusion received fibrinolytic therapy within 6 hours of symptom onset, but nevertheless developed myocardial infarctions of different size. The first patient, without a history of preinfarction angina, developed a large anterior infarction, because there was no time for ischemic preconditioning or development of coronary collateral vessels. The second patient, with a 4-day history of preinfarction angina, had a more favorable outcome-he developed apical necrosis, with greater myocardial viability in the infarct-related area. Conclusion The beneficial effects of angina occurring 24-48h before infarction are resulting from ischemic preconditioning, which reduces cardiac mortality, infarct size and occurrence of life-threatening ventricular arrhythmias. .

  1. Myocardial bridging as a cause of acute myocardial infarction: a case report

    Emiroglu Yunus

    2002-09-01

    Full Text Available Abstract Background Systolic compression of a coronary artery by overlying myocardial tissue is termed myocardial bridging. Myocardial bridging usually has a benign prognosis, but some cases resulting in myocardial ischemia, infarction and sudden cardiac death have been reported. We are reporting a case of myocardial bridging which was complicated with acute myocardial infarction associated with inappropriate blood donation. Case presentation A 33 year-old-man was admitted to our emergency with acute anteroseptal myocardial infarction after a blood donation. The electrocardiography showed sinus rhythm and was consistent with an acute anteroseptal myocardial infarction. We decided to perform primary percutanous intervention (PCI. Myocardial bridging was observed in the mid segment of the left anterior descending coronary artery on coronary angiogram. PCI was canceled and medical follow up was decided. Blood transfusion was made because he had a deep anemia. A normal hemaglobin level and clinical reperfusion was achieved after ten hours by blood transfusion. At the one year follow up visit, our patient was healthy and had no cardiac complaints. Conclusions Myocardial bridging may cause acute myocardial infarction in various clinical conditions. Although the condition in this case caused profound anemia related acute myocardial infarction, its treatment and management was unusual.

    Topaz, On; Luxenberg, Michael; Schumacher, Audrey

    1994-07-01

    Patients who sustain complicated acute myocardial infarction in whom thrombolytic agents either fail or are contraindicated often need mechanical revascularization other than PTCA. In 24 patients with acute infarction complicated by continuous chest pain and ischemia who either received lytics or with contraindication to lytics, a holmium:YAG laser (Eclipse Surgical Technologies, Palo Alto, CA) was utilized for thrombolysis and plaque ablation. Clinical success was achieved in 23/24 patients, with 23 patients (94%) surviving the acute infarction. Holmium:YAG laser is very effective and safe in thrombolysis and revascularization in this complicated clinical setting.

  5. Thrombus aspiration in acute myocardial infarction.

    Mahmoud, Karim D; Zijlstra, Felix

    2016-07-01

    The success of primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is often hampered by incomplete microvascular myocardial reperfusion owing to distal embolization of thrombus resulting in microvascular obstruction. To address this problem, thrombus aspiration devices have been developed that can be used to evacuate coronary thrombus either manually or mechanically. Thrombus aspiration has the potential to reduce the local thrombus load, minimize the need for balloon predilatation, facilitate direct stenting, prevent distal embolization, and ultimately improve myocardial reperfusion. Furthermore, thrombus aspiration has enabled us to study coronary thrombus in vivo, and has facilitated recognition of distinct mechanisms of coronary thrombosis. Clinical trials focusing on manual thrombus aspiration in primary PCI have generally shown improved myocardial reperfusion. However, in two large trials powered for clinical end points, no reduction in 1-year mortality or other adverse clinical events was observed with the use of this strategy. Moreover, one of these trials showed a marginally increased risk of stroke. Consequently, current guidelines do not recommend routine use of thrombus aspiration. Future studies should focus on the identification of subgroups of patients with STEMI who might derive benefit from manual thrombus aspiration, and establish the effect of operator performance on the efficacy and safety of the procedure.

    The mechanism mediating the development of ventricular arrhythmia (VA) after acute myocardial infarction (AMI) is still uncertain. Thrombin receptor (TR) activation has been proven to be arrhythmogenic in many other situations, and we hypothesize that it may participate in the genesis of post-AMI VA. Using a left coronary artery ligation rat model of AMI, we found that a local injection of hirudin into the left ventricle (LV) significantly reduced the ratio of VA durations to infarction sizin...

    Full Text Available INTRODUCTION: Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. OBJECTIVE Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. METHODS A descriptive study was conducted of persons aged >25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room and location (jurisdiction of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. RESULTS A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008. In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged >75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de Ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively. CONCLUSIONS Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies

  15. Thromboxane B2 formation in patients with acute myocardial infarction

    Thromboxane A2 is a stable metabolite of thromboxane B2 which production and release were reported with many of the risk factors related to coronary-artery disease. In 18 patients with acute transmural myocardial infarction serial determinations of thromboxane B2 were performed in the blood having clotted at 370C for 30 min. Significantly less (p < 0.05) of thromboxane B2 was formed in the first week after infarction compared to the control group. Thromboxane B 2 formed in the blood of these patients increased slightly in the recovery period but was still lower than in healthy population. Since thromboxane A2 exerts deleterious effects upon myocardial performance an adaptive protective effect of the decreased thromboxane synthesis in patients with myocardial infarction was suggested.

    Mannino, Joseph A.; Washburn, Richard A.

    1989-03-01

    Mortality from acute myocardial infarction (MI) over the 5 year period 1982 1987 in Brown County, Wisconsin, was analyzed to assess the relationship with environmental temperature. Deaths occurrring on the day of and the day following a significant snowfall as well as deaths occuring in health care facilities were eliminated from consideration because the focus was upon temperature, not snowfall or events within a hospital. These criteria resulted in the inclusion of 1,802 days and 926 cases of acute MI. The mean temperature on the day of death was obtained from climatological data and were grouped into six categories covering a range of temperatures frommyocardial infarction.

    A myocardial infarction is a rare complication which can occur after an exercise stress test. We report a 48-year-old male who was referred to the Mildura Cardiology Practice, Victoria, Australia, in August 2014 with left-sided chest pain. He underwent an exercise stress test which was negative for myocardial ischaemia. However, the patient presented to the Emergency Department of the Mildura Base Hospital 30 minutes after the test with severe retrosternal chest pain. An acute anteroseptal ST segment elevation myocardial infarction was observed on electrocardiography. After thrombolysis, he was transferred to a tertiary hospital where coronary angiography subsequently revealed significant left anterior descending coronary artery stenosis. Thrombus aspiration and a balloon angioplasty were performed. The patient was discharged three days after the surgical procedure in good health.

  3. Acute myocardial infarction. Clinical application of technetium 99m stannous pyrophosphates infarct scintigraphy

    Acute myocardial infarction is being recognized as a spectrum of clinical subsets. This appreciation has been brought about to a large degree by the development of several new tools that can be applied clinically to aid in evaluation of patients with acute infarction, and in some cases to provide short- and long-term prognostic information. In the realm of noninvasive methods, several tests utilizing radiopharmaceuticals and scintillation cameras have emerged and are rapidly becoming reliable diagnostic parameters in patients with coronary disease and infarction. Technetium-99m (stannous) pyrophosphate (TcPYP) scintigraphy, one of the first of these techniques to find clinical use, has been shown to be an accurate indicator of acute transmural myocardial infarction and provides added sensitivity and specificity to the diagnosis. Increased diagnostic accuracy, the dimension of visible localization, and the potential for infarct sizing promise physicians better understanding of a patient's clinical presentation and a more rational approach to management

  4. Justification for intravenous magnesium therapy in acute myocardial infarction

    Rasmussen, H S

    1988-01-01

    Recent studies have shown that patients with acute myocardial infarction (AMI) are magnesium-deficient and develop an additional transient decrease in serum magnesium concentrations (S-Mg c) during the acute phase of the infarct. Animal experiments, as well as studies on humans, have indicated...... that the acute decrease in S-Mg c as well as a more chronic magnesium (Mg) deficiency state are harmful to the myocardium in the setting of acute ischaemia. This knowledge has led during the last couple of years to the performance of four double-blind placebo controlled studies in which the effect of i.......v. magnesium therapy on mortality and incidence of arrhythmias in patients with AMI has been evaluated. Magnesium treatment more than halved the acute mortality and incidence of arrhythmias requiring treatment in three of the four intervention studies. The mechanisms behind the beneficial effect of magnesium...

  5. Reperfusion therapy for acute myocardial infarction: observations from the National Registry of Myocardial Infarction 2.

    Barron, H V; Rundle, A; Gurwitz, J; Tiefenbrunn, A

    1999-01-01

    The National Registry of Myocardial Infarction 2 (NRMI-2) provides a unique opportunity to evaluate the practice patterns among participating cardiology and emergency medicine departments involved in the care of patients with acute myocardial infarction. The data from NRMI-2 suggest that almost 1/3 of all non-transfer-in and non-transfer-out patients are eligible for reperfusion therapy. Furthermore, of those patients who are clearly eligible for reperfusion therapy, 24% are not given this proven therapy. Specifically, women, the elderly, patients without chest pain on presentation, and those patients at highest risk for in-hospital mortality were least likely to be treated with reperfusion therapy. The reason for underuse of reperfusion therapy may in part reflect a concern for adverse bleeding events associated with the use of thrombolytic therapy. The data from NRMI-2 also suggest that patients with contraindications to thrombolysis may be very appropriate for primary angioplasty. Realizing the full potential benefits of reperfusion therapy in terms of reduced cardiovascular morbidity and mortality will require that clinical practice patterns be aligned more closely with the recommended national guidelines, which are based on extensive clinical trial data that show the benefit of reperfusion therapy in a wide range of patients with acute myocardial infarction. By using observational databases, such as the NRMI-2, which describe how clinical care is administered in nonclinical trial settings, we can continually monitor our progress and initiate changes to ensure that patients are given access to the many therapies that have been shown to improve their quality of life and survival.

  7. [Reperfusion therapy for acute myocardial infarction in elderly patients].

    Takata, Jun; Nishinaga, Masanori; Doi, Yoshinori

    2006-11-01

    Although there has been great progress in reperfusion therapy, the role of coronary reperfusion for elderly patients with acute myocardial infarction has not been fully investigated. In general, mean age of the subjects in major trials was about 60 years old and approximately only 10 to 15% of patients were over age 75. On the other hand, large-scale registries such as the US national registry of myocardial infarction (NRMI) showed a higher prevalence of elderly (especially women) in the clinical setting. This discrepancy may be due to the fact that elderly patients with myocardial infarction have some difficulties in the treatment such as severe multi-vessel coronary lesions, non-cardiac complications and relatively high prevalence of adverse reactions to reperfusion therapy. Here we focus on the situation of elderly patients (especially those 75 years or older) with myocardial infarction in the "real world" clinical setting, showing the clinical changes and outcome of our registry in rural Japan: the Kochi AMI (KAMI) registry.

  8. Role of cardiac MRI in acute myocardial infarction

    Erwin Mulia

    2013-02-01

    Full Text Available Mortality in patients with acute myocardial infarction (AMI has decreased significantly and appears to be the result of current reperfusion therapeutic strategies. Reperfusion itself may develop into reperfusion injury. Therefore, management of these patients poses several challenges, such as diagnosing and managing heart failure, identifying persistent or inducible ischaemia, estimating the need for anticoagulation, and assessing overall cardiovascular risk. This case presentation will demonstrate the impact of cardiac magnetic resonance imaging (MRI in the assessment of the pathophysiology of AMI in the current reperfusion era. Cardiac MRI can provide a wide range of clinically useful information which will help clinicians to manage and choose specific therapeutic strategies for AMI patients.

  9. The inflammatory response in myocarditis and acute myocardial infarction

    Emmens, R.W.

    2016-01-01

    This thesis is about myocarditis and acute myocardial infarction (AMI). These are two cardiac diseases in which inflammation of the cardiac muscle occurs. In myocarditis, inflammation results in the elimination of a viral infection of the heart. During AMI, one of the coronary arteries is occluded, causing ischemia and damaged cardiac muscle cells. Here, inflammation removes these damaged cells, so that scar formation can occur. However, for both diseases, inflammation also results in additio...

    Wael Abuzeid; Hatim Al-Lawati; Neil Fam

    2015-01-01

    Dabigatran etexilate is a recently approved direct thrombin inhibitor (DTI), which is superior to warfarin in the prevention of stroke and systemic embolism in patients with atrial fibrillation (AF). However, dabigatran use is associated with an increased risk of myocardial infarction (MI) compared to warfarin. The mechanisms for this association effect remain speculative. We present a case of an acute MI and cardiac arrest in a patient with chronic AF who had been recently switched from warf...

    2013-01-01

    Acute Myocardial Infarction (AMI) is the combined result of environmental factors and personal predispositions. Many factors play a role in AMI including anti-Phospholipid (aPL) antibodies, that may act in the induction of immunological response leading to the development of AMI. Anti-Phosphatidylserine (PS) antibody is detected in various diseases like rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody syndrome. The study of anti-PS antibody in AMI might shed l...

    The electrocardiogram (ECG) remains a crucial tool in the identification and management of acute myocardial infarction (MI). A detailed analysis of patterns of ST-segment elevation may influence decisions regarding the use of reperfusion therapy. The early and accurate identification of the infarct-related artery on the ECG can help predict the amount of myocardium at risk and guide decisions regarding the urgency of revascularization. The specificity of the ECG in acute MI is lim...

    Objectives Evaluate the quality of care provided patients with acute myocardial infarction and compare with similar national and regional data. Design Case series. Setting The Strong Heart Study has extensive population-based data related to cardiovascular events among American Indians living in three rural regions of the United States. Participants Acute myocardial infarction cases (72) occurring between 1/1/2001 and 12/31/2006 were identified from a cohort of 4549 participants. Outcome measures The proportion of cases that were provided standard quality of care therapy, as defined by the Healthcare Financing Administration and other national organizations. Results The provision of quality services, such as administration of aspirin on admission and at discharge, reperfusion therapy within 24 hours, prescription of beta blocker medication at discharge, and smoking cessation counseling were found to be 94%, 91%, 92%, 86% and 71%, respectively. The unadjusted, 30 day mortality rate was 17%. Conclusion Despite considerable challenges posed by geographic isolation and small facilities, process measures of the quality of acute myocardial infarction care for participants in this American Indian cohort were comparable to that reported for Medicare beneficiaries nationally and within the resident states of this cohort.

  3. [Trials with ACE-inhibitors in acute myocardial infarction].

    Dalla Volta, S

    1994-12-01

    In acute myocardial infarction, the results of the trials with ACE-inhibitors have not been always good, in contrast with what has been observed in chronic heart failure. The comparison of these compounds with the placebo has demonstrated lack of reduction of mortality in the study CONSENSUS II, favorable results on the survival as first endpoint and on the secondary endpoints, as reinfarction, heart failure and stroke in the studies SOLVD, AIRE, GISSI 3, ISIS 4, and uncertain (interim report) results in the Chinese study. Nevertheless, the analysis of the recruitment of the patients with acute infarction and the way these patients have been treated seem to be the most important cause of the conflicting results. ACE-inhibitors have proved no efficacy in acute myocardial infarction without signs of left ventricular failure (CONSENSUS II), have worsened the clinical picture and the mortality in patients in shock or with severe heart failure in the acute phase. On the reverse, in presence of mild to moderate left ventricular dysfunction and failure, the use of ACE-inhibitors has been followed by reduction of mortality in the early (AIRE, GISSI 3, ISIS 4), medium term (GISSI 3) and long-term follow-up (up to 4 years in the AIRE study). In parallel with the reduction of the primary endpoint, also secondary endpoints have been favorably influenced by the different ACE-inhibitors. No differences have been observed among the different class of compounds. ACE-inhibitors seem, therefore, to have a clear indication in acute myocardial infarction with mild or moderate signs and symptoms of heart failure. PMID:7634258

  4. Weather fronts and acute myocardial infarction

    Kveton, Vit

    1991-03-01

    Some methodological aspects are discussed of the investigation of acute infarct myocarditis (AIM) in relation to weather fronts. Results of a new method of analysis are given. Data were analysed from about the hour of the onset of symptoms, and led to the diagnosis of AIM either immediately or within a few hours or days (3019 cases observed over 4.5 years during 1982 1986 in Plzen, Czechoslovakia). Weather classification was based on three factors (the type of the foregoing front, the type of the subsequent front, the time section of the time interval demarcated by the passage of the surfaces of the fronts). AIM occurrence increased in particular types of weather fronts: (i) by 30% during 7 12 h after a warm front, if the time span between fronts exceeded 24 h; (ii) by 10% in time at least 36 h distant from the foregoing cold or occlusion front and from the succeeding warm or occlusion front; (iii) by 20% during 0 2 h before the passage of the front, provided the foregoing front was not warm and the interval between fronts exceeded 5 h. AIM occurrence decreased by 15% 20% for time span between fronts > 24 h at times 6 11, 6 23 and 6 35 h before a coming warm or occlusion front (for interfrontal intervals 25 48, 49 72 and possibly > 72 h), and also at 12 23 and possibly 12 35 h before a cold front (for intervals 49 72 and possibly > 72 h), if the foregoing front was cold or an occlusion front.

    Full Text Available BACKGROUND : Although acute myocardial infarction was believed to be an uncommon entity in the young, of late there has been a rising incidence in this group of population. The analysis of its clinical profile, including the etiologic and the risk factors gains much importance, for the preventive purpose. AIMS AND OBJECTIVES: To study the clinical profile of acute MI, including the evaluation of the cardiac enzyme markers, the risk factors, the management and the complications and outcome of this g roup of patients aged 40 years or younger. RESULTS: Majority of patients belonged to the age group of 36 - 40years. 31 patients were overweight and 16 patients were obese. 46 patients (67.64% had anterior wall myocardial infarction, 22 patients had inferior wall myocardial infarction (32.35% and ST - elevation myocardial infarction was found in 69.2% of patients. Smoking/tobacco use was the most common risk factor (64.70% followed by dyslipidemia (60.29%, metabolic syndrome (52.94% diabetes mellitus (52.94 %, hyperhomocysteinemia (52.94%, alcohol consumption (48.52%, hypertension (34%, family history (26.47%, obesity (23.52%. Other than these, two patients had chronic kidney disease stage 3, two female patients were irregular oral contraceptive pill us ers, one was diagnosed as systemic lupus erythematosus and another patient had antiphospholipid antibody syndrome. Conclusions: Apart from early diagnosis and adequate treatment of acute MI in young patients, it is also essential to identify and prevent or control the risk factors at primary and secondary level.

  9. Cardiotrophin-1 in Patients with Acute Myocardial Infarction

    Abdolreza S. Jahromi

    2010-01-01

    Full Text Available Problem statement: Myocardial infarction is the combined result of environmental and personal factors. Prothrombotic factors might play an important role in this phenomenon. Inflammation plays a pivotal role in atherosclerosis and coronary heart disease. Cardiotrophin-1 (CT-1, a member of the IL-6 family of cytokines, was identified as a growth factor for cardiac myocytes that induces cardiomyocyte hypertrophy and stimulates cardiac fibroblasts, protects myocytes from cell death. This study was designed to investigate whether plasma concentration of Cardiotrophin-1 (CT-1, in patients who had the first acute myocardial infarction and to analyze their relationship with traditional cardiovascular risk factors. Approach: This study was carried out on 45 patients with Acute Myocardial Infarction (AMI in their first 24 h of admission as case group and 36 healthy matched individuals were studied as the control. Plasma level of cardiotrophin-1 was determined by enzyme-linked immunosorbent assay and the results were compared. Results: Plasma CT-1 levels in the patients with AMI on admission 615.279±5.109 pmol L-1 were significantly higher than those in the control group 534.767±6.750 pmol L-1 (p = 0.001. Plasma CT-1 level was not correlated with diabetes mellitus, hyperlipidemia, sex, age and smoking. Conclusion: Our findings suggested that high plasma CT-1 level in patients with AMI is indicative of hypercoagulable state that is not related to the traditional cardiovascular risk factors.

    2010-01-01

    Full Text Available Problem statement: Myocardial infarction is the combined result of environmental and personal factors. Data concerning the relation between anti-Phospholipid (aPL antibodies and myocardial infarction in subjects without evidence of overt autoimmune disease are conflicting. Anticardiolipin antibody is detected in various diseases like rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody syndrome. The study of Anticardiolipin antibody in Acute Myocardial Infarction (AMI might shed light on etiologic mechanisms in the pathogenesis of acute coronary syndromes. The purpose of the present study was to determine association of plasma aPL antibodies, namely, anti-Cardiolipin (aCL antibodies, with AMI. Approach: This study recruited 45 patients with the diagnosis of AMI according to WHO criteria in their first 24 h of admission. Thirty six matched individuals were studied as the control group with normal coronary artery angiography. Samples were tested for IgG-class antibodies to cardiolipin by an ELISA and the results were compared. Results: There were not significant differences between plasma level of aCLAs IgG in the patients with AMI on admission ant the control group. Also aCLAs IgG was not correlated with hypertension, diabetes mellitus, hyperlipidemia, sex, age and smoking. Conclusion: Our findings suggest that aCLAs IgG are not indicative of hypercoagulable state in patients with AMI.

  11. Radioimmunoassay of human cardiac tropomyosin in acute myocardial infarction

    Tropomyosin was prepared from fresh human myocardium and antisera raised in rabbits. A sensitive radioimmunoassay was developed for the detection of human cardiac 125I-labelled tropomyosin in human sera down to levels of 1 ng/ml. Values for human cardiac tropomyosin in normal patients ranged from less than 1 to 3 ng/ml. In 18 patients with acute myocardial infarction all had elevated tropomyosin levels ranging from 41 to above 200 ng/ml with a mean peak level of 101 ng/ml. In this study there were no false positive or false negative results. In the initial stages of infarction the time course of appearance and peak levels of cardiac tropomyosin, total creatine kinase and creatine kinase MB isoenzyme were similar. Although total creatine kinase and creatine kinase MB isoenzyme levels were normal after 72 h in patients with single, uncomplicated infarction, cardiac tropomyosin levels were still significantly elevated above normal after this time, being 30-60% of peak values. Radioimmunoassay of human cardiac tropomyosin may prove useful in the diagnosis and in the management of patients with acute myocardial infarction, particularly in the long-term postinfarction period.

    Full Text Available Psychological reactions, risk health behavior and cardiac parameters can influence rehospitalization after acute myocardial infarction.The aim of the paper was to determine the presence of psychological reactions and risk health behavior in patients with acute myocardial infarction on admission as well as the differences after six months.The research included thirty-trhee patients of both sexes, who were consecutively hospitalized due to acute myocardial infarction. A prospective clinical investigation involved the following: semi-structured interview, Mini International Neuropsychiatric Interview (M.I.N.I for pcychiatric disorders, Beck Anxiety Inventory (BAI for measuring the severity of anxiety, Beck Depression Inventory (BDI for measuring the severity of depression, KON-6 sigma test for aggression, Holms-Rahe Scale (H-R for exposure to stressful events, and Health Behavior Questionnaire: alcohol consumption, cigarette smoking, lack of physical activity. Measurement of the same parameters was done on admission and after six months. The differences were assessed using the t-test and chi-square test for p<0.05.On admission, anxiety (BAI=8.15±4.37 and depression (BDI=8.67±3.94 were mild without significant difference after six months in the group of examinees. Aggression was elevated and significantly lowered after six monts (KON-6 sigma =53,26±9, 58:41,42±7.67, t=2,13 for p<0.05. Exposure to stressful events in this period decreased (H-R=113.19±67.37:91,65±63,81, t=3,14 for p<0.05; distribution of physical activity was significantly higher compared to admission values (54.83%: 84.84%. χ2=5.07 for p<0.01.In the group of examinees with acute myocardial infarction in the period of six months, anxiety and depression remained mildly icreased, while the levels of aggression and exposure to stressful events were lowered. Risk health behavior was maintained, except for the improvement in physical activity. In the integrative therapy and

  13. The immune system in atherosclerosis and in acute myocardial infarction

    Antonio Barsotti

    2009-08-01

    Full Text Available Acute myocardial infarction (AMI occurs when the atheromatous process prevents total blood flow through the coronary artery. It was previously thought that progressive luminal narrowing from the continued growth of smooth muscle cells (SMCs in the plaque was the main cause of infarction, however, angiographic studies, have identified culprit lesions that do not cause marked stenosis. Is now evident that plaque activation, rather than stenosis, precipitates ischemia and infarction. Coronary spasm could be involved to some extent, but most cases of AMI are due to the formation of an occluding thrombus on the surface of the plaque; the two major causes of coronary thrombosis are plaque rupture and endothelial erosion. Plaque rupture is detectable in 60- 70% of cases and preferentially occurs when the fibrous cap is thin and partly destroyed. One of the major challenges in modern cardiology is the knowledge of the factors that induce a silent atherosclerotic plaque shifting from a stable to a vulnerable form.

    Topaz, On

    1993-06-01

    We report our clinical experience with a group of 14 patients who presented with acute myocardial infarction. A holmium:YAG laser was applied to the infarct-related artery. This laser emits 250 - 600 mJ per pulse, with a pulse length of 250 microseconds and repetition rate of 5 Hz. Potential benefits of acute thrombolysis by lasers include the absence of systemic lytic state; a shortened thrombus clearing time relative to using thrombolytics; safe removal of the intracoronary thrombus and facilitation of adjunct balloon angioplasty. Potential clinical difficulties include targeting the obstructive clot and plaque, creation of debris and distal emboli and laser-tissue damage. It is conceivable that holmium:YAG laser can be a successful thrombolytic device as its wave length (2.1 microns) coincides with strong water absorption peaks. Since it is common to find an atherosclerotic plaque located under or distal to the thrombotic occlusion, this laser can also be applied for plaque ablation, and the patient presenting with acute myocardial infarction can clearly benefit from the combined function of this laser system.

  19. The effects of different remedies on acute myocardial infarction

    Objective: To investigate the different treatment effects of intravenous thrombolysis vs primary coronary angioplasty and interhospital transfer for primary coronary angioplasty in acute myocardial infarction within 12 hours after onset. Methods: During January 2004 to December 2005, 63 consecutive patients with acute myocardial infarction admitted directly for primary PCI and 25 patients transferred from other hospitals for primary. PCI were compared with 32 patients treated with intravenous thrombolysis. Each patients arrived at hospital within 12 h from chest pain onset. T-test and Chi-square test were used to analyze the rate of mortality, re-infarction, heart failure in-hospital and 1-year latter. Results: Among the 3 groups, for group of intravenous thrombolysis, time interval from arriving to having reflow was the shortest (1.1 ± 0.2 h vs 2.3 ± 1.0 h vs 2.1 ± 1.1 h, P < 0.01), the mortalities in hospital (6.3% vs 3.2% vs 4.0%) and 1-year follow up (12.5% vs 4.8% vs 8.0%)were highest in spite of no statistic difference. After 1 year, the rate of reinfarction in intravenous thrombolysis group is higher than that in PCI group (18.8% vs 4.5%, P < 0.05). Conclusions: The key point of AMI remedy is to open the criminal vessel as fast as possible. Interhospital transfer for PCI is feasible and safe. (authors)

  20. "DETERMINANTS OF PREHOSPITAL DELAY IN PATIENTS WITH ACUTE MYOCARDIAL INFARCTION"

    M. Alidoosti

    2004-05-01

    Full Text Available Determination of pre-hospital delay time of patients with acute myocardial infarction and seeking ways of speeding up the time for reperfusion is an important factor to lower mortality in these patients. This is a cross-sectional study to determine pre-hospital delay time, its components, and related causes and conditions, obtained in 375 patients with prolonged chest pain referred to four hospitals of Tehran University of Medical Sciences. Means of transport to hospital, reasons of ambulance disuse, decision time by the patient and finally the entire time of pre-hospital delay were specified. Suspected factors related to delays of more than 2 and 6 h were scrutinized with chi-square test. Rate of ambulance utility (18.9% directly correlated with age of patients (P<0.05. Principal motives to disuse ambulance insuccession were unrememberance (33.7%, access to private vehicle (32.8% and supposition of sufficient speed of personal reference (18.9%. Pre-hospital delay time was 8.1 ± 9.1 h (mean ± SD in whole patients and 7.6 ± 9.1 h in those with acute myocardial infarction. Delays of more than 2 and 6 hoccurred in 67.5% and 33.6% of patients, respectively. Decision time constitute three fourth of whole pre-hospital delay and was correlated with female gender, older age, history of diabetes, lower level of literacy and nocturnal onset of symptoms. In conclusion, a significant number of patients with acute myocardial infarction have pre-hospital delay of more than 2 and even 6 h, when golden time for thrombolytic therapy has already been elapsed.

  1. [Therapy of acute myocardial infarction in the prehospital setting].

    Arntz, H R

    2008-09-01

    The time period from symptom onset to hospital admission is of outstanding importance for the prognosis of a patient with an acute myocardial infarction. He is threatened by sudden cardiac death triggered by ventricular fibrillation on the one hand and on the other hand this period offers the chance for a timely decision on the optimal reperfusion strategy. A broad spectrum of therapeutic opportunities regarding thrombolysis, antiplatelets and anticoagulation has been proven to be effective in large randomised trials and registries. These results should influence the individual decision on reperfusion treatment as well as the patient's conditions, time lines, logistics and local resources. PMID:18629465

  2. Risk of stroke after acute myocardial infarction among Chinese

    2001-01-01

    @@Following an acute myocardial infarction (AMI), patients have an increased risk of stroke. Estimates of risk are mainly derived from AMI treatment trials or secondary prevention studies. The reported incidence of stroke in Caucasians in the early phase after AMI ranged from 0.5% to 2.5%.1-3 Similar assessment of risk in the Chinese population is lacking. As thrombolytic therapy becomes standard treatment for AMI, there is concern that there may be an increase in haemorrhagic stroke complicating AMI treatment, especially since haemorrhagic stroke is more common in Asian populations.

    2003-01-01

    Full Text Available BACKGROUND and AIMS: Mental stress is considered to be a precipitating factor in acute coronary events. We aimed to assess the association of subjective or 'perceived' mental stress with the occurrence of acute coronary events. SETTINGS AND DESIGN: Prospective case-control survey was carried out in a referral teaching hospital. subjects & METHODS: Consecutive patients with acute myocardial infarction and ST elevation on electrocardiogram who were admitted to the Coronary Care Unit of a referral teaching hospital were enrolled in the study as cases. Controls were unmatched and were enrolled from amongst patients with coronary artery disease who did not have recent acute coronary events. Subjective Stress Functional Classification (SS-FC for the preceding 2-4 weeks was assessed and assigned four grades from I to IV as follows: I - baseline, II - more than usual but not affecting daily routine, III - significantly high stress affecting daily routine and IV - worst stress in life. STATISTICAL ANALYSIS: Proportions of different characteristics were compared using chi-square test with Yates continuity correction. Student's unpaired t test was applied for mean age. 'p' value of < 0.05 was considered statistically significant. RESULTS: SS-FC could be reliably (99% and easily assessed. Eighty (53% of the total 150 patients with acute MI reported 'high' levels of stress (stress class III and IV. This is in contrast to only 30 (20% of 150 healthy controls reporting high stress for the same period (p value < 0.001. CONCLUSION: Patients with acute myocardial infarction report a higher subjective mental stress during 2 to 4 weeks preceding the acute coronary event.

  8. Electrocardiographic localization of infarct related coronary artery in acute ST elevation myocardial infarction

    C.S. Thejanandan Reddy

    2013-07-01

    Full Text Available The electrocardiogram (ECG remains a crucial tool in the identification and management of acute myocardial infarction (MI. A detailed analysis of patterns of ST-segment elevation may influence decisions regarding the use of reperfusion therapy. The early and accurate identification of the infarct-related artery on the ECG can help predict the amount of myocardium at risk and guide decisions regarding the urgency of revascularization. The specificity of the ECG in acute MI is limited by individual variations in coronary anatomy as well as by the presence of preexisting coronary artery disease, particularly in patients with a previous MI, collateral circulation, or previous coronary-artery bypass surgery. The ECG is also limited by its inadequate representation of the posterior, lateral, and apical walls of the left ventricle. Despite these limitations, the electrocardiogram can help in identifying proximal occlusion of the coronary arteries, which results in the most extensive and most severe myocardial infarctions.

  12. Relationship Between Periodontal Disease and Acute Myocardial Infarction

    M Zamirian

    2008-07-01

    Full Text Available Background: Conventional risk factors for coronary artery disease and myocardial infarction do not explain all of the clinical and epidemiological features of the disease. Periodontal disease is a common bacterial and destructive disorder of oral tissues. Many studies demonstrate close association between chronic periodontitis and development of generalized inflammation, vascular endothelial injury, and atherosclesis. Periodontal disease has been convincingly emerging as an important independent risk factor for ischemic heart disease. A case - control study was carried out to assess the prevalence of periodontitis in patients with Acute myocardial Infarction (AMI and evaluate the possible relationship between AMI and chronic periodontitis. Patients and Methods: A number of 160 patients, aged 35 to 70 years old, enrolled in the study. Eighty patients (43 men, 37 women were examined four days after hospitalization due to AMI. Control group consisted of 80 persons (38 men, 42 women with normal coronary angiography. The following periodontal parameters were examined: Plaque index (PI, gingiral index (GI, bleeding on probing (BOP, probing depth (PD, clinical attachment loss (CAL and number of sites with CAL.Results: The case, compared to control showed significantly worse results for some periodontal variables studied: The mean of PD and PD > 3 mm, CAL, and number of sites with CAL, had worse results compared to control despite similar oral hygiene and frequency of brushing. The confounding factors for the present study were found to be hypertension and diabetes. Conclusion: The association between periodontitis and acute myocardial infarction was significant after adjusting for conventional risk factors for AMI.

  13. SIGNIFICANCE OF LIPID PROFILE ESTIMATION IN PATIENT WITH ACUTE MYOCARDIAL INFARCTION

    2013-06-01

    Full Text Available Acute myocardial infarction is one of the important reasons of death and unhealthiness in the world. The present study was undertaken to investigate the changes in serum lipids and lipoproteins in patients with acute myocardial infarction. The levels of lipid profile were significantly changed in the acute myocardial infarction patients. Acute myocardial infarction patients had significantly higher levels of total cholesterol, LDL-cholesterol, TG, Lipoprotein and lower level of HDL-cholesterol, as compared to the control subjects. We found a significant association of lipid profiles with acute myocardial infarction. Reduced serum HDL-cholesterol and increased Serum LDL, Serum TG, Lipoprotein (a, in our study subjects may be the effective reasonable lipid disorders in AMI patients.

    2014-01-01

    It has been found that in 15% of acute myocardial infarction patients' platelets generate reactive oxygen species that can be detected with luminol-enhanced chemiluminescence of platelet-rich plasma within 8-10 days after acute myocardial infarction. This increase in generate reactive oxygen species production coincides with the emergence of CD45(+) platelets. The ability of platelets to carry surface leukocyte antigen implies their participation in exchange of specific proteins in the course of acute myocardial infarction. Future studies of CD45(+) platelets in peripheral blood of acute myocardial infarction patients in association with generate reactive oxygen species production may provide a new insight into the complex mechanisms of cell-cell interactions associated with acute myocardial infarction.

  15. Glycemic Control for Patients With Acute Myocardial Infarction

    Hai-peng XIAO; Juan CHEN

    2009-01-01

    @@ The risk of myocardial infarction increases in patients with diabetes mellitus. The incidence of myocardial in-farction is similar in patients with type 2 diabetes without history of myocardial infarction and in non-diabetic pa-tients with history of myocardial infarction. Diabetes mellitus was considered as a coronary disease equivalent by the National Cholesterol Education Program. Strict glycemic control can improve the long-term outcome of both type 1 and type 2 diabetes mellitus. Whatever with diabetic or non-diabetic, strict glycemic control with in-tensive insulin therapy can reduce the mortality of criti-cally ill patients in hospital. After myocardial infarction, there would be a worse outcome for patients with poor glycemic control, whatever in diabetic or non-diabetic patients with stress hyperglycemia.

  6. Acute Myocardial Infarction: The First Manifestation of Ischemic Heart Disease and Relation to Risk Factors

    Manfroi Waldomiro Carlos

    2002-01-01

    Full Text Available OBJECTIVE: To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. METHODS: We carried out a cross-sectional study of 104 patients with previous acute myocardial infarction, who were divided into 2 groups according to the presence or absence of angina prior to acute myocardial infarction. We assessed the presence of angina preceding acute myocardial infarction and risk factors, such as age >55 years, male sex, smoking, systemic arterial hypertension, lipid profile, diabetes mellitus, obesity, sedentary lifestyle, and familial history of ischemic heart disease. On coronary angiography, the severity of coronary heart disease and presence of left ventricular hypertrophy were assessed. RESULTS: Of the 104 patients studied, 72.1% were males, 90.4% were white, 73.1% were older than 55 years, and 53.8% were hypertensive. Acute myocardial infarction was the first manifestation of ischemic heart disease in 49% of the patients. The associated risk factors were systemic arterial hypertension (RR=0.19; 95% CI=0.06-0.59; P=0.04 and left ventricular hypertrophy (RR=0.27; 95% CI=0,.8-0.88; P=0.03. The remaining risk factors were not statistically significant. CONCLUSION: Prevalence of acute myocardial infarction as the first manifestation of ischemic heart disease is high, approximately 50%. Hypertensive individuals more frequently have symptoms preceding acute myocardial infarction, probably due to ventricular hypertrophy associated with high blood pressure levels.

  12. Outcome of cardiogenic shock complicating acute myocardial infarction

    Objective: To analyze the characteristics and in-hospital outcome of patients with cardiogenic shock (CS) complicating acute myocardial infarction (AMI) and to evaluate the influence of urgent coronary revascularization on in-hospital mortality. Materials and Methods: All consecutive patients with AMI and CS, admitted at The Aga Khan University Hospital, Karachi Pakistan, during the year 2001 were reviewed. A pre-designed questionnaire was used for data collection. Analysis was done using the SPSS statistical package. Results: Out of 615 patients with AMI, 53 (8.6%) had CS. Mean age was 60.9 plus minus 10.7 years. 62.3% were men, 52.8% were hypertensive and 43.4% were diabetic. Most infarcts were anterior in location (56.6%). Thrombolytic therapy (Streptokinase) was administered to 43.5% of patients with ST segment elevation myocardial infarction. 64.2% required ventilator support while swan ganz was used in 37.7%. Intra-aortic balloon pump was inserted in 39.6%. Ventricular tachycardia was the most common complication (39.6%). Overall in-hospital mortality was 54.7%. CS associated with mechanical complications had 80% in-hospital mortality. In patients without mechanical complications (n=48), in-hospital mortality was significantly lower in the revascularization group (31.6% vs. 65.5%, p-value = 0.021). However, there were significant differences in the baseline characteristics in the two groups because of the selection bias. Conclusion: CS occurring in patients with AMI has an extremely poor prognosis. Patients selected for revascularization strategy has favorable in-hospital outcome. (author)

  15. Recurrent Acute Myocardial Infarction in Patients with Immune Thrombocytopenic Purpura

    Fengyi Shen

    2014-01-01

    Full Text Available Immune thrombocytopenic purpura (ITP, also known as idiopathic thrombocytopenic purpura, is an acquired immune-mediated disease of adults and children characterized by a transient or persistent decrease of platelets and, depending upon the degree of thrombocytopenia, an increased risk of bleeding. The use of standard treatments for acute myocardial infarction (AMI, such as antiplatelet agents and anticoagulants, pose serious problems in patients with ITP due to the potential higher risk of bleeding complications. There are no current guidelines available for management of ITP patients with AMI. In this brief review of the limited available literature, we discuss the proposed pathophysiological link between ITP and arterial thrombosis and the challenging medical and interventional treatment of these patients.

    2014-09-01

    Raman spectroscopy is a rapidly non-invasive technique with great potential for biomedical research. The aim of this study was to evaluate the feasibility of using Raman spectroscopy of human saliva for acute myocardial infarction (AMI) detection. Raman spectroscopy measurements were performed on two groups of saliva samples: one group from patients (n=30) with confirmed AMI and the other group from healthy controls (n=31). The diagnostic performance for differentiating AMI saliva from normal saliva was evaluated by multivariate statistical analysis. The combination of principal component analysis (PCA) and linear discriminate analysis (LDA) of the measured Raman spectra separated the spectral features of the two groups into two distinct clusters with little overlaps, rendering the sensitivity of 80.0% and specificity of 80.6%. The results from this exploratory study demonstrated that Raman spectroscopy of human saliva can serve as a potentially clinical tool for rapid AMI detection and screening.

    Objective To investigate the influencing factors for prehospital delay in patients with acute myocardial infarction (AMI).Methods A total of 807 consecutive patients with AMI who presented to the emergency department of Beijing Anzhen Hospital were analyzed. The influence of several potential risk factors on the prehospital delay time (PDT) was evaluated by comparing patients admitted more than 2 hours after onset of chese pain with those admitted within 2 hours after onset. Results Among 807 patients, 402 came to the hospital within 2 hours while the others arrived at the hospital after 2 hours. The median PDT was 130 min. Among the potential variables, advanced age, history of diabetes mellitus, occurrence of symptom at night and use of emergency medical service significantly affected PDT by multivariate analysis. Conclusion Interventions aimed at reducing the prehospital delay in AMI should primarily focus on the awareness of the risk and help-seeking behavior of patients.

  20. Diagnosing and treating acute myocardial infarction in pregnancy.

    Merrigan, Orla

    2012-02-01

    Acute myocardial infarction (AMI) in pregnancy is a very rare occurrence. However, statistics indicate high mortality rates, with a maternal death rate at 20-37%. Nursing and medical care of AMI in pregnancy is a very complex issue. Risk factors such as stress, smoking, obesity, high cholesterol and family history of heart disease may increase the risk of AMI in pregnancy. There are a variety of challenges for the nurse caring for this patient, as the presenting signs and symptoms of AMI in pregnancy can mimic regular pregnancy symptoms and therefore may be misdiagnosed. There is limited nursing literature on this topic to guide and educate nurses. Recommendations need to be implemented across multiple nursing settings. There is a need for both national and international guidelines on care of this type of patient. There is also a need for policies to be in place and links within the hospital setting and the community.

  1. Percutaneous coronary intervention for acute myocardial infarction with mitral regurgitation.

    Tu, Yan; Zeng, Qing-Chun; Huang, Ying; Li, Jian-Yong

    2016-09-01

    Ischemic mitral regurgitation (IMR) is a common complication of acute myocardial infarction (AMI). Current evidences suggest that revascularization of the culprit vessels with percutaneous coronary artery intervention (PCI) or coronary artery bypass grafting can be beneficial for relieving IMR. A 2.5-year follow-up data of a 61-year-old male patient with ST-segment elevation AMI complicated with IMR showed that mitral regurgitation area increased five days after PCI, and decreased to lower steady level three months after PCI. This finding suggest that three months after PCI might be a suitable time point for evaluating the possibility of IMR recovery and the necessity of surgical intervention of the mitral valve for AMI patient.

  2. Clinical Features of Acute Myocardial Infarction in Elderly Patients

    Shiraki,Teruo

    2011-12-01

    Full Text Available The aim of this study was to clarify the prevalence of coronary risk factors in order to characterize the prognostic factors in elderly patients and to also identify any factors beneficial for the prevention of further cardiac events and death. We studied 888 patients with ST-elevation acute myocardial infarction who were admitted within 48h of symptom onset. The patients were divided into 3 groups according to age for comparison of variables:a younger group (n=99 aged<50, a middle-aged group (n=435>51 years but<70 years and an elderly group (n=354 aged>71 years. The elderly group had higher rates of female gender, pulmonary congestion, in-hospital mortality, and atrial fibrillation and a higher plasma concentration of high-sensitivity CRP (hs-CRP (p<0.05. Hypertension, diabetes mellitus, and dyslipidemia were more common in the middle-aged group (p<0.05. The prevalence of smokers and the plasma level of total cholesterol, LDL-cholesterol and triglycerides were lower in the elderly group (p<0.05. The grade of collateral circulation was highest in the elderly group, but the success rate of reperfusion therapy was lowest. Multiple regression analysis showed that age, pulmonary congestion, CKD and hs-CRP were predictors of in-hospital mortality.This investigation indicated that elderly patients with acute myocardial infarction have different clinical characteristics than younger patients. A specific algorithm might be needed in elderly patients, and could use hs-CRP, eGFR and atrial fibrillation as factors.

  3. Frequency of dyslipidaemia in young patients with acute myocardial infarction

    Objective: To study the frequency of dyslipidaemia in young patients aged between 20-40 years, with Acute Myocardial Infarction in our population. Study design: Descriptive study Place and duration of Study: Coronary Care Unit (CCU) of Armed Forces Institute of Cardiology (AFIC) National Institute of Heart Diseases (NIHD), Rawalpindi from December 2008 to May 2009. Subjects and Methods: One hundred patients of acute myocardial infarction (AMI) fulfilling the World Health Organization (WHO) diagnostic criteria of AMI, having ages between 20-40 years, were included in the study after full informed consent using non-probability consecutive sampling. Blood samples for serum lipid profile were taken after 12 hours fasting (within 24 hours of presentation), and analyzed in laboratory of AFIC. Individual patients' results were compiled with respect to age, gender, serum total cholesterol, serum triglycerides, serum low density lipoprotein (LDL) cholesterol, serum very low density lipoprotein (VLDL) cholesterol and serum high density lipoprotein (HDL) cholesterol. The data was entered in SPSS (version 11.0) and analyzed. Results: Of the 100 patients with AMI, 47 were found to have dyslipidaernia. Hypertriglyceridaernia was the most common lipid abnormality as it was found in 32 (68.1 %) patients; followed by raised serum VLDL, hypercholesterolemia, raised serum LDL and low serum HDL found in 25 (53.2%), 16 (34.0%), 4 (8.5%) and 2 (4.3%) patients respectively. Out of 47 patients with dyslipidaemia, 28 (59.6%) had more than one lipid abnormality. Conclusion: Frequency of dyslipidaemia in young patients with AMI in our population is high. (author)

  5. X-ray characteristics of heart failure in patients with acute myocardial infarction

    Results of chest biomedical radiography in 250 men aged 22-69 years who had acute myocardial infarction were evaluated. Data were compared with the results of ECG, echocardiography, Judkins coronarography, and left ventriculography. X-ray signs of pulmonary venous hypertension in acute myocardial infarction, even not followed by cardiomegalia suggest lower left ventricular myocardial contractility. In this connection, the significance of follow-up X-ray monitoring becomes higher. In 25% of the young patients (aged 22-40 years) with prior acute myocardial infarction, the dimensions of the heart may be in the normal ranges even in the presence of X-ray signs of venous congestion. If there are no signs of mitral regurgitation in patients with ischremic heart disease, the enlarged left atrium may be regarded as an indirect X-ray sign of reduced left ventricular contractility.

    2012-01-01

    Full Text Available Background/Aim. The heart has traditionally been considered as a static organ without capacity of regeneration after trauma. Currently, the more and more often asked question is whether the heart has any intrinsic capacities to regenerate myocytes after myocardial infarction. The aim of this study was to present the existence of the preserved muscle fibers in the myocardial scar following myocardial infarction as well as the presence of numerous cells of various size and form that differently reacted to the used immunohistochemical antibodies. Methods. Histological, histochemical and immunohistochemical analyses of myocardial sections taken from 177 patients who had died of acute myocardial infarction and had the myocardial scar following myocardial infarction, were carried out. More sections taken both from the site of acute infarction and scar were examined by the following methods: hematoxylin-eosin (HE, periodic acid schiff (PAS, PAS-diastasis, Masson trichrom, Malory, van Gieson, vimentin, desmin, myosin, myoglobin, alpha actin, smoth muscle actin (SMA, p53, leukocyte common antigen (LCA, proliferating cell nuclear antigen (PCNA, Ki-67, actin HHF35, CD34, CD31, CD45, CD45Ro, CD8, CD20. Results. In all sections taken from the scar region, larger or smaller islets of the preserved muscle fibers with the signs of hypertrophy were found. In the scar, a large number of cells of various size and form: spindle, oval, elongated with abundant cytoplasm, small with one nucleus and cells with scanty cytoplasm, were found. The present cells differently reacted to histochemical and immunohistochemical methods. Large oval cells showed negative reaction to lymphocytic and leukocytic markers, and positive to alpha actin, actin HHF35, Ki-67, myosin, myoglobin and desmin. Elongated cells were also positive to those markers. Small mononuclear cells showed positive reaction to lymphocytic markers. Endothelial and smooth muscle cells in the blood vessel walls

  8. Acute myocardial infarction and infarct size: do circadian variations play a role?

    Ibáñez B

    2012-08-01

    Full Text Available Aída Suárez-Barrientos,1 Borja Ibáñez1,21Cardiovascular Institute, Hospital Clínico San Carlos, 2Centro Nacional de Investigaciones Cardiovasculares, Madrid, SpainAbstract: The circadian rhythm influences cardiovascular system physiology, inducing diurnal variations in blood pressure, heart rate, cardiac output, endothelial functions, platelet aggregation, and coronary arterial flow, among other physiological parameters. Indeed, an internal circadian network modulates cardiovascular physiology by regulating heart rate, metabolism, and even myocyte growth and repair ability. Consequently, cardiovascular pathology is also controlled by circadian oscillations, with increased morning incidence of cardiovascular events. The potential circadian influence on the human tolerance to ischemia/reperfusion has not been systematically scrutinized until recently. It has since been proven, in both animals and humans, that infarct size varies during the day depending on the symptom onset time, while circadian fluctuations in spontaneous cardioprotection in humans with ST-segment elevation myocardial infarction (STEMI have also been demonstrated. Furthermore, several studies have proposed that the time of day at which revascularization occurs in patients with STEMI may also influence infarct size and reperfusion outcomes. The potential association of the circadian clock with infarct size advocates the acknowledgment of time of day as a new prognostic factor in patients suffering acute myocardial infarction, which would open up a new field for chronotherapeutic targets and lead to the inclusion of time of day as a variable in clinical trials that test novel cardioprotective strategies.Keywords: cardioprotection, circadian rhythm, reperfusion injury, ST-segment elevation myocardial infarction

  9. MOEMS-based cardiac enzymes detector for acute myocardial infarction

    Amritsar, Jeetender; Stiharu, Ion G.; Packirisamy, Muthukumaran; Balagopal, Ganesharam; Li, Xing

    2004-10-01

    Biomedical applications of MOEMS are limited only by the mankind imagination. Precision measurements on minute amounts of biological material could be performed by optical means with a remarkable accuracy. Although available in medical laboratories for general purposes, such analyzers are making their way directly to the users in the form of dedicated equipment. Such an example is a test kit to detect the existence of cardiac enzymes in the blood stream. Apart from the direct users, the medical personnel will make use of such tools given the practicality of the kit. In a large proportion of patients admitted to the hospital suspected of Acute Myocardial Infarction (AMI), the symptoms and electrocardiographic changes are inconclusive. This necessitates the use of biochemical markers of myocardial damage for correct exclusion or conformation of AMI. In this study the concept of MOEMS is applied for the detection of enzyme reaction, in which glass spectrums are scanned optically when enzyme molecules adsorb on their surface. This paper presents the optical behavior of glass spectrums under Horseradish Peroxide (HRP) enzyme reaction. The reported experimental results provide valuable information that will be useful in the development of biosensors for enzymatic detection. This paper also reports the dynamic behavior of different glass spectrums.

Randomized controlled trials of acute myocardial infarction which have used CMR parameters as a primary endpoint are presented.

  13. [Reperfusion therapy in acute myocardial infarction: primary percutaneous transluminal coronary angioplasty or thrombolysis?].

    Bilkis, Valdas; Kibarskis, Aleksandras; Abraitis, Vytautas

    2004-01-01

    Randomized controlled trials that compared primary percutaneous transluminal coronary angioplasty with thrombolysis have shown that primary angioplasty is more effective than intravenous thrombolysis in reducing mortality and morbidity in patients with acute myocardial infarction. Three large myocardial infarction registries - MITI, NRMI-2 and French registry - failed to show an advantage of primary angioplasty compared with thrombolysis. One of the latest trials mentioned in this paper restored the place of primary angioplasty as superior to thrombolysis in acute myocardial infarction. Data of patients treated with primary percutaneous transluminal coronary angioplasty in Clinic of Cardiology of Vilnius University are presented. PMID:15079110

    Aim: To assess the prognostic value of 64-section multidetector computed tomography (MDCT) to predict follow-up myocardial dysfunction and functional recovery after reperfusion therapy in patients with acute myocardial infarction (MI) as defined by echocardiography. Materials and methods: After reperfusion therapy for acute MI, 71 patients underwent two-phase contrast-enhanced MDCT and follow-up echocardiography. MDCT findings were compared with echocardiographic findings using kappa statistics. The areas under the receiver operating characteristic curves (AUCs) and the odds ratios (ORs) of early perfusion defects (EPD), delayed enhancement (DE), and residual perfusion defects (RPD) for predicting follow-up myocardial dysfunction and functional recovery were calculated on a segmental basis. Results: The presence of transmural EPD (EPD{sub TM}) or RPD showed good agreement (k = 0.611 and 0.658, respectively) with follow-up myocardial dysfunction, while subendocardial EPD (EPD{sub sub}) or subendocardial DE (DE{sub sub}) showed fair agreement with follow-up myocardial dysfunction (k = 0.235 and 0.234, respectively). The AUC of RPD (0.796) was superior (p < 0.001 and 0.031, respectively) to those of EPD{sub TM} (0.761) and DE{sub TM} (0.771). The presence of EPD{sub TM}, DE{sub TM}, and RPD were significant, independent positive predictors of follow-up myocardial dysfunction (OR = 6.4, 1.9, and 9.8, respectively). EPD{sub TM} was a significant, independent negative predictor of myocardial functional recovery (OR = 0.13). Conclusion: Abnormal myocardial attenuation on two-phase MDCT after reperfusion therapy may provide promising information regarding myocardial viability in patients with acute MI.

  5. Takotsubo cardiomyopathy vs acute myocardial infarction: diagnostic utility of subtle ECG differences

    Syed, Asma Saba; Khalid, Umair

    2011-01-01

    The clinical findings of Takatsubo Cardiomyopathy and acute myocardial infarction can be very similar. While Takatsubo cardiomyopathy rarely leads to severe complications, acute myocardial infarction can be life threatening. Treatment of both these conditions is different and so it is imperative for clinicians to have a high index of suspicion for either. Several EKG differences between the two entities have been proposed. This article summarizes the EKG changes most likely seen in Takatsubo ...

  12. Trends in acute myocardial infarction management: use of the National Registry ofMyocardial Infarction in quality improvement.

    French, W J

    2000-03-01

    Cardiovascular disease, including acute myocardial infarction (AMI), is the leading cause of death in the United States and was the primary disease category among hospital discharges in 1996. Efforts to improve hospital care of patients with AMI should be measured and assessed routinely for appropriateness of care and improvement of medical staff performance. The National Registry of Myocardial Infarction (NRMI), an observational Phase IV study, has enrolled > 1 million AMI patients since 1990, and is now in its third phase. NRMI 3 collects patient data and facilitates the measurement of improvement in care and outcomes, while allowing participating institutions to benchmark their performance against national, state, and like-hospital data. Three measures from NRMI 3 are accepted for the Joint Commission on Accreditation of Healthcare Organizations' ORYX initiative: (1) aspirin use within 24 hours of AMI diagnosis; (2) door-to-drug time for fibrinolysis; and (3) no initial reperfusion strategy given to eligible patients.

    The present-day optimal treatment of patients with acute myocardial infarction (AMI) is reviewed. The prehospital phase should be as brief as possible. Emergency observation and treatment in hospital should be initiated without delay. Schematic stages for mobilization have been discarded and free mobilization is recommended. Routine acute intervention with thrombolysis is recommended for patients in whom symptoms have been present for 6-12 hours and treatment with Aspirin is recommended. Beta-blocking agents are recommended for patients with increased risk after discharge. Treatment of ventricular and supraventricular arrhythmias, block and cardiac failure are reviewed in detail. Patients without complications should be monitored for three to five days and may be discharged after seven to ten days. Exercise ECG should be carried out at discharge to assess the working capacity, ischaemia and subjective reaction. The importance of good patient information is emphasized. Cessation of smoking, control of lipids and blood pressure are important as secondary interventions. As far as possible, outpatient control should be offered after discharge. The criteria for referral to specialized cardiological departments are established both for emergency and elective referral. Patients under the age of 70 years with high risk for repeated AMI or death after discharge (with residual ischaemia) should possibly be referred for coronary arteriography. PMID:2567543

    2014-01-01

    Background While sleep apnea (SA) might be a modifiable cardiovascular risk factor, recent data suggest that SA is severely underdiagnosed in patients after acute myocardial infarction (MI). There is limited evidence about day-night variation of onset of MI on dependence of having SA. We therefore investigated the prevalence of SA and examined the day-night variation of onset of MI in acute MI patients. Methods We prospectively studied 782 consecutive patients admitted to the hospital with the diagnosis of acute MI. All subjects underwent sleep evaluations using a portable device after at least 48 hours post-admission. Using the apnea-hypopnea index (AHI), groups were defined as patients without SA (<5 events/hour), mild SA (5–15 events/hour), moderate SA (15–30 events/hour), and severe SA (≥30 events/hour). Results Almost all patients (98%) underwent urgent coronary angiography and 91% of patients underwent primary PCI. Using a threshold of AHI ≥ 5 events/hour, SA was present in 65.7% of patients after acute MI. Mild SA was present in 32.6%, moderate in 20.4% and severe in 12.7%. The day-night variation in the onset of MI in all groups of SA patients was similar to that observed in non-SA patients. From 6AM–12PM, the frequency of MI was higher in both SA and non-SA patients, as compared to the interval from 12AM–6AM (all p<0.05). Conclusion There is a high prevalence of SA in patients presenting with acute MI. Peak time of MI onset in SA patients was between 6AM–noon, similar to that in the general population. Whether diagnosis and treatment of SA after MI will significantly improve outcomes in these patients remains to be determined. PMID:25064202

  1. Proinsulin and insulin profile in acute myocardial infarction

    Proinsulin and insulin in 104 and glucagon in 10 cases were estimated by radioimmunoassay (RIA) technique in uncomplicated cases of acute myocardial infarction (A.M.I.), matched against 44 and 5 controls respectively. Patients were divided into group A and B based on oral glucose tolerance test (G.T.T.) done on the following morning after admission. Group A comprised of 65 and group B comprised of 49 patients with normal and abnormal G.T.T. respectively. The tests were repeated prior to discharge from the hospital at the end of 6th week. The initial values of insulin and glucagon were found to be significantly raised in both the groups but came down to normal in group A whereas they remained unchanged in group B in the follow up study. Proinsulin values in group A were not significantly changed both in initial and follow up study. In group B proinsulin values were found to be significantly low both initially and in the follow up study. G.T.T. in group B remained abnormal even at the end of the 6th week. (author)

  3. Understanding prehospital delay behavior in acute myocardial infarction in women.

    Waller, Cynthia G

    2006-12-01

    Studies demonstrate that acute myocardial infarction (AMI) mortality can be reduced if reperfusion therapy is initiated within 1 hour of AMI symptom onset. However, a considerable number of men and women arrive at the emergency department outside of the time frame for thrombolytic and angioplasty effectiveness. This is especially true for women who have been shown to delay longer than men due to their prehospital decision-making process utilized. With a mean total delay time greater than 4 hours, the time interval from symptom onset to transport activation to the hospital consumes the majority of the prehospital phase of emergency cardiac care. The health belief model, self-regulation model, theory of reasoned action, and theory of planned behavior have all been used to describe the prehospital decision-making process of both men and women with an AMI and the variables that impact that process. These models have identified the importance of symptom attribution to cardiac-related causes as a target variable for research and interventions related to care-seeking behavior. PMID:18340239

  4. Clinical Application of Heart Rate Variability after Acute Myocardial Infarction

    HeikkiVeliHuikuri

    2012-02-01

    Heart rate (HR variability has been extensively studied in patients surviving an acute myocardial infarction (AMI. The majority of studies have shown that patients with reduced or abnormal HR variability/turbulence have an increased risk of mortality within few years after an AMI. Various measures of HR dynamics, such as time-domain, spectral, and non-linear measures of HR variability, as well as HR turbulence, have been used in risk stratification of post-AMI patients. The prognostic power of various measures, except of those reflecting rapid R-R interval oscillations, has been almost identical, albeit some non-linear HR variability measures, such as short-term fractal scaling exponent, and HR turbulence, have provided somewhat better prognostic information than the others. Abnormal HR variability predicts both sudden and non-sudden cardiac death after AMI. Because of remodeling of the arrhythmia substrate after AMI, early measurement of HR variability to identify those at high risk should likely be repeated later in order to assess the risk of fatal arrhythmia events. Future randomized trials using HR variability/turbulence as one of the pre-defined inclusion criteria will show whether routine measurement of HR variability/turbulence will become a routine clinical tool for risk stratification of post-AMI patients.

    Full Text Available BACKGROUND: Although experimental studies have demonstrated that reduced glutathione (GSH is involved in cellular protection from deleterious effects of oxygen free radicals in ischaemia and reperfusion, there are controversial data on the correlation between levels of GSH and the ischaemic process. AIM: The present study was planned to evaluate erythrocyte GSH levels in patients with acute myocardial infarction (AMI. SETTING & DESIGN: Erythrocyte GSH levels were determined in 22 patients with AMI and 15 age matched healthy volunteers served as control. MATERIAL & METHODS: Erythrocyte GSH levels were measured by using Bentler in AMI and control patients. Also lipid profile was analyzed enzymatically in these subject. STATISTICS: The values were expressed as means +/- standard deviation (SD and data from patients and controls was compared using student′s ′t′-test. Results and CONCLUSION: GSH levels were significantly decreased in AMI as compared to control (p<0.001. Also, total cholesterol and triglycerides were higher is AMI subjects (p<0.05. These finding suggest that depressed GSH levels may be associated with enhanced protective mechanism to oxidative stress in AMI.

  6. Solar Activity, Different Geomagnetic Activity Levels and Acute Myocardial Infarction

    Dimitrova, Svetla; Jordanova, Malina; Stoilova, Irina; Taseva, Tatiana; Maslarov, Dimitar

    Results on revealing a possible relationship between solar activity (SA) and geomagnetic activity (GMA) and acute myocardial infarction (AMI) morbidity are presented. Studies were based on medical data covering the period from 1.12.1995 to 31.12.2004 and concerned daily distribution of patients with AMI diagnose (in total 1192 cases) from Sofia region on the day of admission at the hospital. Analysis of variance (ANOVA) was applied to check the significance of GMA intensity effect and the type of geomagnetic storms, those caused by Magnetic Clouds (MC) and by High Speed Solar Wind Streams (HSSWS), on AMI morbidity. Relevant correlation coefficients were calculated. Results revealed statistically significant positive correlation between considered GMA indices and AMI. ANOVA revealed that AMI number was signifi- cantly increased from the day before (-1st) till the day after (+1st) geomagnetic storms with different intensities. Geomagnetic storms caused by MC were related to significant increase of AMI number in comparison with the storms caused by HSSWS. There was a trend for such different effects even on -1st and +1st day.

  7. IS OPIUM ADDICTION A RISK FACTOR FOR ACUTE MYOCARDIAL INFARCTION?

    "S. M. Sadr Bafghi

    2005-06-01

    Full Text Available There is a misconception among our people that opioids may prevent or have ameliorating effects in the occurrence of cardiovascular diseases. In this study we evaluated 556 consecutive male patients hospitalized due to acute myocardial infarction (MI in city of Yazd, from May 2000 to October 2001 and compared the characteristics of opium addicts to non opium users. Prevalence of opium addiction in MI patients was 19% in comparison with 2-2.8% in general population. There were not any differences in prevalence of traditional risk factors between opium users and non-users. Overall, in-hospital mortality was 18.6 percent among opium users and 6.2 percent among non-opium users (unadjusted odd ratio, 1.3; 95% confidence interval, 0.7 to 2.7, P = 0.2. After adjustment for the differences in the baseline features (age and other risk factors, odds ratio increased to 2.2 (95 percent confidence interval, 0.9 to 5.1. It seems that opium addiction may work as a risk factor in cardiovascular disease.

    Metanephric adenoma (MA) is a rare neoplasm that acounts for 0.2% of adult renal neoplasms. MAs are typically discover incidentally during detailed examinations for nonspecific symptoms such as abdominal or flank pain, hematuria, fever and palpable abdominal mass. Additionally, polycythemia has occasionally been reported as well. Herein we describe a case of metanephric adenoma which was an incidental finding in the course of a clinical autopsy in a patient with complete AV block and polycythemia. Histologically, the tumor was composed of small and uniform tubular structures reminiscent of renal tubuli, without signs of cellular atypia and pleomorphism. Such tumor histomorphology was consistent with the diagnosis of metanephric adenoma. Thrombosis is a common complication of polycythemia that often causes death. Polycythemia with an increasing number of blood cells causes hyperviscosity and, in 20-40% of cases, lethal thrombosis or hemorrhage. Hyperviscosity and coronary artery disease in our patient caused acute myocardial infarction with the subsequent rupture of posterior left ventricle wall and hemopericardium. PMID:27471365

  9. Financial stress and outcomes after acute myocardial infarction.

    Full Text Available BACKGROUND: Little is known about the association between financial stress and health care outcomes. Our objective was to examine the association between self-reported financial stress during initial hospitalization and long-term outcomes after acute myocardial infarction (AMI. MATERIALS AND METHODS: We used prospective registry evaluating myocardial infarction: Event and Recovery (PREMIER data, an observational, multicenter US study of AMI patients discharged between January 2003 and June 2004. Primary outcomes were disease-specific and generic health status outcomes at 1 year (symptoms, function, and quality of life (QoL, assessed by the Seattle Angina Questionnaire [SAQ] and Short Form [SF]-12. Secondary outcomes included 1-year rehospitalization and 4-year mortality. Hierarchical regression models accounted for patient socio-demographic, clinical, and quality of care characteristics, and access and barriers to care. RESULTS: Among 2344 AMI patients, 1241 (52.9% reported no financial stress, 735 (31.4% reported low financial stress, and 368 (15.7% reported high financial stress. When comparing individuals reporting low financial stress to no financial stress, there were no significant differences in post-AMI outcomes. In contrast, individuals reporting high financial stress were more likely to have worse physical health (SF-12 PCS mean difference -3.24, 95% Confidence Interval [CI]: -4.82, -1.66, mental health (SF-12 MCS mean difference: -2.44, 95% CI: -3.83, -1.05, disease-specific QoL (SAQ QoL mean difference: -6.99, 95% CI: -9.59, -4.40, and be experiencing angina (SAQ Angina Relative Risk = 1.66, 95%CI: 1.19, 2.32 at 1 year post-AMI. While 1-year readmission rates were increased (Hazard Ratio = 1.50; 95%CI: 1.20, 1.86, 4-year mortality was no different. CONCLUSIONS: High financial stress is common and an important risk factor for worse long-term outcomes post-AMI, independent of access and barriers to care.

  11. C-Reactive protein predicts acute myocardial infarction during high-risk noncardiac and vascular surgery

    Oscar M. Martins

    2011-01-01

    Full Text Available BACKGROUND: High-sensitivity C-reactive protein predicts cardiovascular events in a wide range of clinical contexts. However, the role of high-sensitivity C-reactive protein as a predictive marker for perioperative acute myocardial infarction during noncardiac surgery is not yet clear. The present study investigated high-sensitivity C-reactive protein levels as predictors of acute myocardial infarction risk in patients undergoing high-risk noncardiac surgery. METHODS: This concurrent cohort study included patients aged >50 years referred for high-risk noncardiac surgery according to American Heart Association/ACC 2002 criteria. Patients with infections were excluded. Electrocardiograms were performed, and biomarkers (Troponin I or T and/or total creatine phosphokinase and the MB fraction (CPK-T/MB were evaluated on the first and fourth days after surgery. Patients were followed until discharge. Baseline high-sensitivity C-reactive protein levels were compared between patients with and without acute myocardial infarction. RESULTS: A total of 101 patients undergoing noncardiac surgery, including 33 vascular procedures (17 aortic and 16 peripheral artery revascularizations, were studied. Sixty of the patients were men, and their mean age was 66 years. Baseline levels of high-sensitivity C-reactive protein were higher in the group with perioperative acute myocardial infarction than in the group with non-acute myocardial infarction patients (mean 48.02 vs. 4.50, p = 0.005. All five acute myocardial infarction cases occurred in vascular surgery patients with high CRP levels. CONCLUSIONS: Patients undergoing high-risk noncardiac surgery, especially vascular surgery, and presenting elevated baseline high-sensitivity C-reactive protein levels are at increased risk for perioperative acute myocardial infarction.

  12. Frequency of adverse outcomes of acute myocardial infarction in patients with stress hyperglycem)a

    Objective: To determine the frequency of in-hospital adverse outcomes of acute myocardial infarction in patients with stress hyperglycemia. Methodology: This was a descriptive cross sectional study conducted from August 2010 to January 2011 in Cardiology department, Lady Reading Hospital, Peshawar. Patients of age 25-70 years, of either gender, non-diabetic with acute myocardial infarction with stress hyperglycemia were included. Random blood sugar >144 mg/dl was taken as stress hyperglycemia for patients at presentation of acute myocardial infarction. Patients were monitored for electrical complications such as atrial fibrillation, ventricular tachycardia, ventricular fibrillation and complete heart block and mechanical complications such as cardiac pulmonary edema and cardiogenic shock during hospital stay. The statistical analysis was performed using the statistical package for social sciences (SPSS Ver. 15.0). Results: A total of 341 patients having acute myocardial infarction with stress hyperglycemia were studied. The mean age was 56.35 +- 9.748 (95% CI 57.39 - 55.31). Male were 58.1% (n=198). The frequency of various major in-hospital electrical adverse outcomes of acute myocardial infarction with stress hyperglycemia were atrial fibrillation (AF) 15.8%, ventricular tachycardia (VT) 11.7%, ventricular fibrillation (VF) 10.9% and complete heart block (CHB) 6.7%, while mechanical adverse outcomes were cardiac pulmonary edema (CPE) 7.9% and cardiogenic shock (CS) 11.7%. Conclusion: Stress hyperglycemia has adverse impact on outcomes of patients presenting with acute myocardial infarction. Among electrical and mechanical complications of acute myocardial infarction in patients with stress hyperglycemia, the two most frequent in-hospital adverse outcomes were atrial fibrillation and cardiogenic shock, respectively.

    2014-01-01

    In conclusion, circulating levels of IL-6 and CRP, but not the soluble forms of the receptor (sIL-6R or the receptor signalling subunit (sgp130 were associated with the extent of myocardial necrosis. The biological importance of the IL-6/gp130-mediated signalling pathways in patients with acute myocardial infarction and dysglycemia should be further elucidated.

    2012-01-01

    Thrombolysis with intravenous tissue plasminogen activator (t-PA) is currently an approved therapy for patients with acute ischemic stroke.Acute myocardial infarction (AMI) immediately following t-PA treatment for stroke is a rare but serious complication.A case of acute myocardial infarction (MI) following IV t-PA infusion for acute stroke was observed.This is a 52-year-old male with a known history of hypertension and chest pain,who subsequently developed MI four hours after IV t-PA was administered for acute ischemic stroke.The disruption of intra-cardiac thrombus and subsequent embolization to the coronary arteries may be an important mechanism.In addition.spontaneous recanalization of infarct-related arteries may be associated with 9reater myocardial salvage and better prognosis.

  5. Risk factors in young patients of acute myocardial infarction

    Background: Ischemic heart disease is a leading cause of death throughout the world. CAD has been recognized among younger age group more frequently in recent years. Very limited data is available regarding the prevalence of various risk factors in our younger patients that is why this study was planed. Objectives of the study were to look for the risk factors most prevalent in our young patient of first Acute Myocardial Infarction. And to also look for the number of Risk Factors present in each patient. Methods: We studied 100 consecutive patients from 16-45 years of age presenting with first acute MI. Twelve risk factors were studied namely, gender, family history of premature CAD, smoking hypertension, diabetes, dyslipidemia, obesity, mental stress (type A personality), alcohol, oral contraceptive pills (OCPs), physical activity, and diet. We divided the patients into two groups. Group A with patients 35 years of age or less and group B with patients 36-45 years of age. All risk factors were compared in both the groups. Results: Smoking, diabetes mellitus, dyslipidemia and hypertension were statistically different between the two groups. Frequency wise risk factors were lined up as male sex (91%) Diet (66%), Dyslipidemia (62%), smoking (46%), Type A personality(46%), family history (32%), diabetes mellitus (28%), sedentary lifestyle (26%), hypertension (22%), obesity (17%), alcohol (3%), and OCPs (0%) Most of the patients that is 94% had 3 or more risk factors. Conclusion: Smoking, hypertension, diabetes and dyslipidemia are the major modifiable risk factors in our young adults. If a young male who is smoker or a young female who is diabetic, presents in emergency room with chest pain, always suspect coronary artery disease. Other conventional risk factors are also prevalent but alcohol and OCPs are not a major health problem for us. (author)

  6. [Time costs cardiac muscle tissue--prehospital therapy of acute myocardial infarct--a case report].

    Eschenburg, G; Pappert, D; Ohlmeier, H

    2003-01-01

    Symptoms of an acute myocardial infarction are a common reason for calling the emergency physician. Pre-hospital mortality caused by cardiac infarction is constantly high. The main potential for decreasing infarction mortality lies in the pre-hospital period. The problems and prospects of treatment in the early period are described in the case of a 73-year-old patient with an acute anterior infarction. The diagnostic and therapeutic approach is shown and discussed in this concrete case, taking into consideration the guidelines for diagnostics and therapy of acute myocardial infarction in the pre-hospital period of the German Society for Cardiology. A particular focus is the management of pre-hospital thrombolysis, the preconditions, realization and risks of which are described. In this context, the experience and competence of the emergency physician is prerequisite for the exact diagnosis and therapy. Furthermore, the importance of a smooth transition from pre-hospital therapy to intensive care is emphasized. PMID:12666508

  7. Differentiation of acute myocardial infarction from chronic myocardial scar with MRI

    The coherent steady-state free precession (SSFP) pulse sequence is increasingly being used in cine imaging for evaluating the cardiac function. Compared to the spoiled gradient echo MRI, which has usually been performed for cardiac cine imaging, the SSFP imaging sequence provides a higher signal-to- noise ratio (SNR) by recycling the residual transverse magnetization, and there is less of an inflow effect by using a very short repetition time. A few studies have recently reported that contrast-enhanced (CE) cine-SSFP imaging could be used for estimating the viability of infarcted myocardium with or without the simultaneous evaluation of the ventricular function. Since the contrast of the SSFP sequence imaging is based on the ratio of T2 to T1, T1-shortening contrast-enhancement is shown as hyperenhancement, which is similar to that in the delayed-enhanced T1-imaging. In this issue of the Korean Journal of Radiology, Kim et al. have reported that the CE-cine-SSFP sequence could be used for differentiating the acutely infarcted myocardium from chronic myocardial scar with a sensitivity of 95.8%. This was a new approach for evaluating the age of myocardial infarction (MI) by using MRI

    2014-09-01

    The aim of the current study was to confirm the effect and elucidate the mechanism of bone marrow mesenchymal stem cells (BMSCs) in acute myocardial infarction (AMI). AMI was induced in mini‑swine by ligating the left anterior descending coronary artery, and BMSCs (1x107) were injected via a sterile microinjection into the ischemic area. Six months postoperatively, electrocardiograph‑gated single photon emission computed tomography revealed that the myocardial filling defect was reduced and the left ventricular ejection fraction was improved in the BMSC group compared with the control group (P<0.05). Histopathological examination indicated that, in the BMSC treatment group, the percentage of survived myocardial tissue and the vessel density were increased, and the percentage of apoptosis was decreased compared with controls (P<0.05). Reverse transcription‑polymerase chain reaction results indicated that the expression levels of multiple inflammatory factors were significantly upregulated in the BMSC group compared with levels in the control group (P<0.05). In conclusion, the present study demonstrated that BMSC injection significantly improved cardiac function and reduced infarct size in six months, indicating that this method may be valuable for future study in clinical trials.

    2016-07-01

    While progress has been made in improving survival following myocardial infarction, this injury remains a major source of mortality and morbidity despite modern reperfusion therapy. While one approach has been to develop therapies to reduce lethal myocardial cell reperfusion injury, this concept has not translated to the clinics, and several recent negative clinical trials raise the question of whether reperfusion injury is important in humans undergoing reperfusion for acute ST segment elevation myocardial infarction. Therapy aimed at reducing myocardial cell death while the myocytes are still ischemic is more likely to further reduce myocardial infarct size. Developing new therapies to further reduce left ventricular remodeling after the acute event is another approach to preserving structure and function of the heart after infarction. Such therapy may include chronic administration of pharmacologic agents and/or therapies developed from the field of regenerative cardiology, including cellular or non-cellular materials such as extracellular matrix. The optimal therapy will be to administer agents that both reduce myocardial infarct size in the acute phase of infarction as well as reduce adverse left ventricular remodeling during the chronic or healing phase of myocardial infarction. Such a dual approach will help optimize the preservation of both cardiac structure and function. PMID:26612091

  11. Depressive symptoms are associated with mental stress-induced myocardial ischemia after acute myocardial infarction.

    Jingkai Wei

    Full Text Available Depression is an adverse prognostic factor after an acute myocardial infarction (MI, and an increased propensity toward emotionally-driven myocardial ischemia may play a role. We aimed to examine the association between depressive symptoms and mental stress-induced myocardial ischemia in young survivors of an MI.We studied 98 patients (49 women and 49 men age 38-60 years who were hospitalized for acute MI in the previous 6 months. Patients underwent myocardial perfusion imaging at rest, after mental stress (speech task, and after exercise or pharmacological stress. A summed difference score (SDS, obtained with observer-independent software, was used to quantify myocardial ischemia under both stress conditions. The Beck Depression Inventory-II (BDI-II was used to measure depressive symptoms, which were analyzed as overall score, and as separate somatic and cognitive depressive symptom scores.There was a significant positive association between depressive symptoms and SDS with mental stress, denoting more ischemia. After adjustment for demographic and lifestyle factors, disease severity and medications, each incremental depressive symptom was associated with 0.14 points higher SDS. When somatic and cognitive depressive symptoms were examined separately, both somatic [β = 0.17, 95% CI: (0.04, 0.30, p = 0.01] and cognitive symptoms [β = 0.31, 95% CI: (0.07, 0.56, p = 0.01] were significantly associated with mental stress-induced ischemia. Depressive symptoms were not associated with ischemia induced by exercise or pharmacological stress.Among young post-MI patients, higher levels of both cognitive and somatic depressive symptoms are associated with a higher propensity to develop myocardial ischemia with mental stress, but not with physical (exercise or pharmacological stress.

    Results of collaborative studies on revealing a possible relationship between solar activity (SA) and geomagnetic activity (GMA) and pre-hospital acute myocardial infarction (AMI) morbidity are presented. Studies were based on medical data from Bulgaria and Azerbaijan. Bulgarian data, covering the period from 01.12.1995 to 31.12.2004, concerned daily distribution of number of patients with AMI diagnose (in total 1192 cases) from Sofia Region on the day of admission at the hospital. Azerbaijani data contained 4479 pre-hospital AMI incidence cases for the period 01.01.2003-31.12.2005 and were collected from 21 emergency and first medical aid stations in Grand Baku Area (including Absheron Economical Region with several millions of inhabitants). Data were "cleaned" as much as possible from social and other factors and were subjected to medical and mathematical/statistical analysis. Medical analysis showed reliability of the used data. Method of ANalysis Of VAriance (ANOVA) was applied to check the significance of GMA intensity effect and the type of geomagnetic storms - those caused by magnetic clouds (MC) and by high speed solar wind streams (HSSWS) - on AMI incidences. Relevant correlation coefficients were calculated. Results were outlined for both considered data. Results obtained for the Sofia data showed statistically significant positive correlation between considered GMA indices and AMI occurrence. ANOVA revealed that AMI incidence number was significantly increased from the day before till the day after geomagnetic storms with different intensities. Geomagnetic storms caused by MC were related to significant increase of AMI number in comparison with the storms caused by HSSWS. There was a trend for such different effects even on -1st and +1st day for the period 1995-2004. Results obtained for the Baku data revealed trends similar to those obtained for Sofia data. AMI morbidity increment was observed on the days with higher GMA intensity and after these days

    Advances in the management of myocardial infarction have resulted in substantial reductions in morbidity and mortality. However, after acute treatment a number of diagnostic and prognostic questions often remain to be answered, whereby cardiac imaging plays an essential role. For example, some patients will sustain early mechanical complications after infarction, while others may develop significant ventricular dysfunction. Furthermore, many individuals harbour a significant burden of residual coronary disease for which clarification of functional ischaemic status and/or viability of the suspected myocardial territory is required. Cardiac magnetic resonance (CMR) imaging is well positioned to fulfil these requirements given its unparalleled capability in evaluating cardiac function, stress ischaemia testing and myocardial tissue characterisation. This review will focus on the utility of CMR in resolving diagnostic uncertainty, evaluating early complications following myocardial infarction, assessing inducible ischaemia, myocardial viability, ventricular remodelling and the emerging role of CMR-derived measures as endpoints in clinical trials.

  18. Detection of experimental acute myocardial infarction in dogs with electron beam CT

    Objective: The value and limitation of discovering the site, shape, density and size of acute myocardial infarction with enhanced volume scans of electron beam computed tomography (EBCT) in experimental dogs were assessed. Methods: The anterior descending and circumflex branches of the left coronary artery were ligated and infarction in the wall of left ventricle was created in six dogs. Enhancement volume scan was made with a EBCT scanner at 1.5, 6, 12, and 20 hour after the ligation and CT sectional images of dog heart were obtained. After finishing the scanning, the dogs were then scarified, and the samples were sent for electron and optic microscopes for pathologic examination. The morphologic findings of myocardial ischemia and infarction in CT images were carefully analysed. The CT numbers and the ratios of left ventricular myocardial and luminal CT number (M/L) in the myocardial ischemic and infarcted areas and normal areas were calculated. Results: The typical myocardial infarction in areas ligated were confirmed by ECG and pathology 20 hours after ligation. The site and shape of acute myocardial infarction were clearly shown on the EBCT images. The density of the ischemia and infarction area was significantly lower than that of the normal myocardium (P < 0.001). M/Ls of the low density areas and normal areas were 13.2% and 32.9%, respectively. The difference was significant (P < 0.001). Conclusions: With adequate scanning technique, the site shape, density and size of acute myocardial ischemia and infarction can be accurately assessed by EBCT

  19. C-Reactive Protein and Complement Are Important Mediators of Tissue Damage in Acute Myocardial Infarction

    Griselli, M; Herbert, J.; Hutchinson, W. L.; Taylor, K. M.; Sohail, M; Krausz, T.; Pepys, M. B.

    1999-01-01

    Myocardial infarction in humans provokes an acute phase response, and C-reactive protein (CRP), the classical acute phase plasma protein, is deposited together with complement within the infarct. The peak plasma CRP value is strongly associated with postinfarct morbidity and mortality. Human CRP binds to damaged cells and activates complement, but rat CRP does not activate complement. Here we show that injection of human CRP into rats after ligation of the coronary artery reproducibly enhance...

  20. Altered gene expression pattern in peripheral blood mononuclear cells in patients with acute myocardial infarction.

    Marek Kiliszek

    Full Text Available BACKGROUND: Despite a substantial progress in diagnosis and therapy, acute myocardial infarction (MI is a major cause of mortality in the general population. A novel insight into the pathophysiology of myocardial infarction obtained by studying gene expression should help to discover novel biomarkers of MI and to suggest novel strategies of therapy. The aim of our study was to establish gene expression patterns in leukocytes from acute myocardial infarction patients. METHODS AND RESULTS: Twenty-eight patients with ST-segment elevation myocardial infarction (STEMI were included. The blood was collected on the 1(st day of myocardial infarction, after 4-6 days, and after 6 months. Control group comprised 14 patients with stable coronary artery disease, without history of myocardial infarction. Gene expression analysis was performed with Affymetrix Human Gene 1.0 ST microarrays and GCS3000 TG system. Lists of genes showing altered expression levels (fold change >1.5, p<0.05 were submitted to Ingenuity Pathway Analysis. Gene lists from each group were examined for canonical pathways and molecular and cellular functions. Comparing acute phase of MI with the same patients after 6 months (stable phase and with control group we found 24 genes with changed expression. In canonical analysis three pathways were highlighted: signaling of PPAR (peroxisome proliferator-activated receptor, IL-10 and IL-6 (interleukin 10 and 6. CONCLUSIONS: In the acute phase of STEMI, dozens of genes from several pathways linked with lipid/glucose metabolism, platelet function and atherosclerotic plaque stability show altered expression. Up-regulation of SOCS3 and FAM20 genes in the first days of myocardial infarction is observed in the vast majority of patients.

    BACKGROUND: Arterial hypertension is a major risk factor for cardiovascular events. The prognosis for hypertensive patients after acute myocardial infarction (MI) is uncertain because of the sparse and somewhat contradictionary data. HYPOTHESIS: Our study aimed to investigate the importance of...... hypertension to prognosis after an MI in patients receiving contemporary medical therapy. METHODS: We performed a retrospective study using a large register from the Bucindolol Evaluation in Acute myocardial infarction Trial (BEAT). The register comprised 3,326 patients admitted between June 1998 and August.......9-1.2, p = 0.6). Adjustment for further covariates did not change the result. CONCLUSION: Our study showed that after an acute MI the survival rate of patients with and without a history of hypertension was identical when they received contemporary medical therapy....

    A 41-year-old male bodybuilder was admitted with acute inferior myocardial infarction. The patient had been using oxymetholone and methenolone to increase his performance for 15 years and quitted smoking three years before. He underwent successful primary percutaneous coronary intervention (PCI) and bare metal stenting for total occlusion of the proximal right coronary artery. Angiography also showed a critical lesion in the left anterior descending (LAD) coronary artery. Five hours after primary PCI, the patient had severe right flank pain. Abdominal computed tomography showed a large renal infarction in the right kidney. Subcutaneous enoxaparin was added to dual antiplatelet treatment. Doppler renal ultrasound performed on the eighth day showed findings of reperfusion in the right kidney and normal-size kidneys. Transthoracic echocardiography demonstrated disappearance of previously detected thrombus remnant in the left ventricle and only mild hypokinesia around the apical and middle segments of the inferior and inferoseptal walls. The patient was discharged on the 10th day. Renal arteriography during elective LAD intervention 18 days after discharge showed complete revascularization, stent patency, and improved blood flow. This is the first case of renal infarction that developed in the early hours of primary PCI, despite effective anticoagulant and antiplatelet treatment. Intensive coronary artery and left ventricular thrombi may be explained by the use of anabolic steroids. PMID:20935436

  8. MR study of acute myocardial infarction with injection of Gd-DOTA (Fifteen patients)

    We studied 15 patients 4 to 8 days after myocardial infarction by using ECG gated MR before and after administration of 0.2 mmol/kg Gd-DOTA. The diagnosis in each patient was confirmed by electrocardiographic criteria, elevated levels of fractionated creatine kinase (CK) isoenzyme, thallium scintigraphy, ventriculography and coronarography. T1-weighted, spin-echo images, were obtained before and immediately after injection of Gd-DOTA and were repeated 15 min later. The site of infarction was visualized in 10 patients as an area of high signal intensity after the injection of Gd-DOTA. Contrast between normal and infarcted myocardium was greatest 15 min after injection. Three patients were excluded because of failure to acquire adequate MR studies. In 2 other patients the infarct was not detected. Before injection of Gd-DOTA, only 2 infarcts were detected. These results suggest that Gd-DOTA can improve MR visualization and detection of acute myocardial infarction

    The accurate measurement of myocardial salvage is critical to the ongoing refinement of reperfusion strategies in acute myocardial infarction (AMI). Cardiac magnetic resonance imaging (CMR) can define the area at risk in AMI by the presence of myocardial oedema, identified by high signal intensity on T{sub 2}-weighted imaging with a short inversion time inversion-recovery (STIR) sequence. In addition, myocardial necrosis can be identified with CMR delayed contrast enhanced imaging. In this prospective study we examined the relationship of acute oedema and necrosis with impaired microvascular reperfusion. We also evaluated acute oedema as a marker of the area at risk in AMI, for the purposes of documenting myocardial salvage. CMR was performed on 15 patients with (AMI), within 24 h of successful percutaneous coronary intervention (PCI). Left ventricular (LV) systolic dysfunction was defined by a systolic thickening <40% (severe <20%). Microvascular reperfusion was evaluated during the acute phase of contrast wash-in. CMR was repeated 3 months post-PCI to evaluate recovery of LV function and final infarct size. Myocardial salvage was defined as the percentage of the area at risk that was not infarcted on follow up CMR. There was a significant correlation between impaired microvascular reperfusion and the extent of segmental oedema (R = 0.363, P < 0.01), but not myocardial necrosis (R = 0.110, P > 0.5). The extent of myocardial salvage correlated with recovery of systolic function (R = 0.241, P < 0.05), which was strongest in LV segments with severely reduced systolic function (R = 0.422, P < 0.01). Conclusions: In acutely reperfused AMI, oedema can be used to identify the area at risk for the purpose of calculating myocardial salvage. The correlation between myocardial oedema and reperfusion status suggests a pathological role of acute oedema in the impairment of microvascular reperfusion.
