Background & Aim: The effect of food and drink consumption and their variation on acute myocardial infarction incidence has been investigated in several studies. The objective of the present study was to investigate correlation between nutritional risk factors and acute myocardial infarction. Patients & Methods: This case-control study involved 250 patients with acute myocardial infarction ...
BACKGROUND Myocardial infarction causes irreversible loss of cardiomyocytes and may lead to loss of ventricular function, morbidity and mortality. Infarct size is a major prognostic factor and reduction of infarct size has therefore been an important objective of strategies to improve outcomes. In experimental studies, glucagon-like peptide 1 and exenatide, a long acting glucagon-like peptide 1...
A new method of visualizing acute myocardial infarction in humans following intravenous injection of 15 mCi-5 mg of 99mTc stannous pyrophosphate in 23 patients is reported. Fifteen patients had histories suggestive of acute myocardial infarction and subsequently developed electrocardiogram and enzyme changes that confirmed the clinical diagnosis. Eleven of the 15 patients were scanned 3-5 days ...
OBJECTIVE We recently demonstrated that transfusion of anemic animals up to 100 g/L hemoglobin with fresh blood protects the heart from ischemic injuries following myocardial infarction. Erythropoietin has cardioprotective effects independent of its erythropoietic activity. The objective of this study was to compare the cardioprotective effects of erythropoietin treatment to fresh-blood transfu...
AIMS The aim of this study was to evaluate seven methods for quantifying myocardial oedema [2 standard deviation (SD), 3 SD, 5 SD, full width at half maximum (FWHM), Otsu method, manual thresholding, and manual contouring] from T2-weighted short tau inversion recovery (T2w STIR) and also to reassess these same seven methods for quantifying acute infarct size following ST-segment myocardial infa...
INTRODUCTION MRL is a strain of mice with the unusual ability to recover from injuries without forming scar tissue. It was recently reported that the MRL mice can recover with little or no scar formation following a cryogenically induced myocardial infarction of the right ventricle. These findings suggest that scarless recovery from myocardial injury is possible in mammalian ventricles. If appl...
A survey was made to determine the knowledge of nurses working in coronary care units regarding assessing paint and rendering nursing care to clients with acute myocardial infarction in hospitals affiliated with the ministry of health services and medical education (Tehran, 1995). A total of 120 nurses working in coronary care units were selected randomly to participate in this study. The t...
Background and Objective: Myocardial infarction is a prevalent cardiovascular disorder in Iran. Considering the complications of myocardial infarction that affect every aspect of the patients' life, the quality of life of these patients is of utmost importance. The present study aimed to evaluate the effect of an intervention based on the BASNEF model on the quality of life of patients with myo...
OBJECTIVES This study evaluates the association between microvascular obstruction and myocardial salvage, determined by cardiac magnetic resonance performed both in the acute stage of myocardial infarction and after 4 months. METHODS In patients with acute ST-elevation myocardial infarction treated by primary percutaneous coronary intervention, myocardial salvage, infarct size, left ventricul...
The distance from the midline to the left heart border measured in a standardized manner on calibrated chest roentgenograms was determined serially in 125 patients after acute myocardial infarction. This external left heart dimension (LHD) was compared to the normal value, and its prognostic value was assessed during early and late follow-up periods (average 10, range 2-31 months). Within 96 ho...
