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...

background: myocardial infarction is a fatal symbol of cardiovascular diseases, which usually occurs in people over 45 years. however, the incidence of factors such as obesity, high blood pressure, diabetes and metabolic syndrome has increased the risk of developing early cardiovascular diseases in the middle-aged people. this study was conducted to compare the clinical manifestation of myocard...

ST segment depression in leads remote from those showing ST elevation during acute myocardial infarction has been attributed to benign electrical phenomena, distant myocardial ischaemia, or extensive myocardial damage. Eighty four consecutive survivors under 55 years of age with a first transmural myocardial infarction were studied. All patients had exercise tests six weeks after infarction and...

acute myocardial infarction (mi) during pregnancy is rare and mi due to prinzmetal's angina is much rarer. we present a 35-year-old, obese, multigravida, and pre-eclamptic woman, who developed acute anterior wall mi at the 30th week of gestation. on coronary angiography, the second obtuse marginal branch was totally occluded and the right coronary artery (rca) was normal. three days later, she ...

Background: Ethylene glycol is a toxic alcohol which is used in brake fluid, antifreeze, coolants, preservatives and chemical solvents. Ethylene glycol poisoning usually results in depression of the central nervous system, renal insufficiency and cardiopulmonary compromise, while laboratory findings include metabolic acidosis, increased anion gap, increased osmolar gap and calcium oxalate cryst...
