conclusions a significant proportion of coronary atherosclerotic plaques in cadavers with confirmed acute myocardial infarction were detected to be infected with cytomegaloviruses while no infections of c. pneumoniae and h. pylori were detected. patients and methods sixty cadavers in two equal groups were analyzed. acute myocardial infarction group included cadavers with acute myocardial infarc...

conclusions the door-to-needle (dtn) time, in a standard setting, is recommended to be less than 30 minutes. according to the results of this study, the dtn time is comparatively two times longer in females and afternoon and night shifts. different variables including emergency staff, physicians, patients’ characteristics, and environmental/physical factors induced this difference. results in t...

Introduction: Regarding the association between climate, seasons and myocardial infarction, a cross-sectional study was carried out in Shiraz and Bandar Abbas in Iran. Methods: All patients with diagnosis of acute myocardial infarction living in Shiraz and Bandar Abbas were included in the study during 2011-2013. Demographic data were extracted from the patients’ hospital records. Data w...

background: standard methods for the measurement of myocardial perfusion are invasive and require cardiac catheterization or the use of radioisotope dyes. the coronary sinus blood flow (csbf) is an appropriate criterion for the efficacy of myocardial perfusion. this study sought to measure csbf via transthoracic echocardiography (tte) in patients with acute myocardial infarction (ami) and to as...

results mean age of patients was 59.47 (sd = 12.48) years, of which 75 (75.8%) were male and 24 (24.2%) were female. based on univariable analysis, white blood cell (wbc) count, pain duration, lv function, maximal st-change, thrombus grade and eccentricity were identified as predictors of the no-reflow phenomenon. after multivariable logistic regression: wbc count and thrombus grade remained th...

acute chest pain is an important and frequently occurring symptom in patients. chest pain is often a sign of ischemic heart disease. chest pain due to suspected acute coronary syndrome (acs) is responsible for a large and increasing number of hospital attendances and admissions. current practice for suspected acs involves troponin testing 10–12 hours after symptom onset to diagnose myocardial i...

background : kernel smoothing method is a non-parametric or graphical method for statistical estimation. in the present study was used a kernel smoothing method for finding the death hazard rates of patients with acute myocardial infarction. methods : by employing non-parametric regression methods, the curve estimation, may have some complexity.  in this article, four indices of epanechnikov, b...
