Acute myocardial infarction causes depression of left ventricular function, but the capacity of the ventricle to recover from such an injury remains unknown. This problem was explored by measuring left ventricular function in eight intact conscious dogs before, 1 hr after, and again 6-8 days after myocardial infarction. Acute myocardial infarction was produced using a technique which entails gr...

"Echoventriculography", an echocardiographic method specially developed to scan the regional function of the left ventricle, is introduced for studying left ventricular wall motion alteration in patients with acute myocardial infarction. Purposeful probe directions, a 2:1 magnification, and careful adjustment of the gain and reject levels allowed a direct echocardiographic scanning of practical...

OBJECTIVE To investigate whether coronary stenting limits myocardial injury and preserves left ventricular function. DESIGN AND SETTING Prospective multicentre case-control study of primary percutaneous transluminal coronary angioplasty (PTCA) with and without stenting, performed in seven cardiovascular centres. SUBJECTS AND METHODS 45 consecutive patients with acute myocardial infarction w...

background: more than half of myocardial infracted (mi) patients have no conventional risk factors. regarding the belief that opium addiction has a protective effect on heart diseases, addiction prevalence has unfortunately increased in recent years. this study was conducted to investigate the effect of opium addiction on patients with acute myocardial infarction. methods: this case-control stu...

Although ST-segment abnormalities during acute myocardial infarction are clinically important, the total thoracic distribution of these repolarization potentials has not been reported. To provide this information, 24 patients with acute myocardial infarction were studied. Isopotential body surface maps were constructed from potentials sensed by 150 anterior and posterior electrodes. Patterns fr...

INTRODUCTION A rare electrocardiographic finding of hyperkalemia is ST segment elevation or the so called 'pseudoinfarction' pattern. It has been suggested that hyperkalemia causes the 'pseudoinfarction' pattern not only through its direct myocardial effects, but also through other mechanisms, such as anoxia, acidosis, and coronary artery spasm. CASE PRESENTATION A 33-year-old Caucasian woman...

Myocardial ischemia (MI) resulting in infarction is an important cause of mortality and morbidity worldwide. Acute ischaemia rapidly impairs myocardial contractile function. Myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. Hibernation is now thought to be...

Objective—To investigate whether coronary stenting limits myocardial injury and preserves left ventricular function. Design and setting—Prospective multicentre case–control study of primary percutaneous transluminal coronary angioplasty (PTCA) with and without stenting, performed in seven cardiovascular centres. Subjects and methods—45 consecutive patients with acute myocardial infarction who w...

Myocardial imaging with technetium-99m stannous polyphosphate was performed on 46 patients. Eleven patients had no cardiac disease, 22 had acute myocardial infarction, and 13 had stable arteriosclerotic heart disease. Distinct patterns of myocardial activity were noted: (1) the patients with no obvious cardiac disease showed no cardiac activity; (2) stable arteriosclerotic heart disease showed ...

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 elev...
