objective: this study aimed to determine the association of cardiac risk factors and the risk of acute myocardial infarction (ami) in emergency department (ed) patients with non-diagnostic ecg changes. methods: this cross-sectional study was conducted in the ed of imam hossein hospital during a period of one year. in this study, patients with symptoms suggestive of ami including chest pain, dys...

BACKGROUND Quantitative measures of myocardial perfusion defect severity from acute (99m)Tc-sestamibi tomographic images (nadir) have correlated closely with collateral and residual antegrade blood flow during acute myocardial infarction. The purpose of this study was to determine whether a viability threshold could be identified from this measure in patients with acute myocardial infarction tr...

Frank lead vectorcardiograms (VCG) from four carefully selected patient subgroups (226 patients) were analyzed to develop optimal criteria for the diagnosis of anterior myocardial infarction. Specificity was evaluated using 100 healthy volunteers under age 30 and 80 patients with normal left ventriculogram and normal coronary arteriograms. Sensitivity was determined using 25 patients with evolu...

T HE AVAILABILITY of continuous electrocardiographic monitoring techniques has resulted in recognition that conduction disturbances occur more frequently in patients with acute myocardial infarction than was previously thought to be the case. Complete atrioventricular (A-V) block has been reported in up to 9% of patients who have had acute infarcts,1 and bundle-branch block has been recorded in...

Serum IgE and beta 2 microglobulin levels were determined in 31 patients suffering from acute myocardial infarction and 30 patients with other forms of ischemic heart disease. The levels of these parameters were studied on the first, third and seventh day after the onset of disease. The immunological method used for the determinations was ELISA Patients with myocardial infarction showed an...

Background: The left ventricular problem is a prominent acute myocardial infarction (AMI) complication. It has been demonstrated that rapid reperfusion reduces mortality and improves (LV) function. There dearth of information on thrombus (LVT) in the current era primary percutaneous coronary intervention (PPCI). Aim: To estimate frequency patients who have experienced an anterior wall at Karach...

INTRODUCTION AND OBJECTIVES The goal of this study was to analyze the value of electrocardiography in predicting the site of the lesion in the left anterior descending coronary artery, in relation to the first septal and the first diagonal branches, in patients with acute anterior myocardial infarction. METHOD Ninety consecutive patients who were admitted to the coronary unit with acute anter...

We report a case of a 44-year-old male with variant angina who developed acute anterior myocardial infarction 2 weeks following demonstration of normal left coronary artery. This experience provides inferential evidence that myocardial ischemia resulting from coronary spasm may progress into myocardial infarction.

T HE AVAILABILITY of continuous electrocardiographic monitoring techniques has resulted in recognition that conduction disturbances occur more frequently in patients with acute myocardial infarction than was previously thought to be the case.
