1/3. Fatal arrhythmia in a juvenile athlete due to myocardial hypertrophy and infarction.This report is a case history of a 16-year-old highly trained athlete who suffered from ventricular fibrillation during exhaustive physical activity. After resuscitation and admission into hospital ECG revealed posterior wall infarction. thrombolytic therapy was advised and ST-segment elevation reversed. Within 48 h cerebral edema evolved due to hypoxic brain damage and the subject deceased after 16 days despite prolonged maximum antiedematous therapy. autopsy confirmed the diagnosis of concentric myocardial hypertrophy (total heart weight 568 g) without signs of coronary artery disease. Systemic inflammatory diseases and drug abuse were ruled out by lab studies, evidence for viral infection was not found. Thus, relative coronary insufficiency in regard to myocardial hypertrophy during excessive athletic activity must be viewed as cause for the fatal arrhythmia.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/3. Acute myocardial infarction in sickle cell anemia.Cardiovascular dysfunction consistent with ischemia has been observed during episodes of painful crisis and following periods of heavy physical exertion in individuals with sickle cell disease. Similar findings have been observed in other individuals while taking the alpha-adrenergic agonist pseudoephedrine. However, acute myocardial infarction is extremely rare. The authors describe a case of sudden death in a child with sickle cell disease due to acute myocardial infarction and suggest that heavy exertional stress and use of pseudoephedrine may have precipitated the event.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/3. Cardiac lipoma with changes of ST segment and T wave on electrocardiogram.We report a case of cardiac lipoma found by chance as a cause of ST-T changes which suggested left ventricular hypertrophy. A 38-year-old man was completely asymptomatic and was incidentally found to have an abnormal electrocardiogram during a regular physical examination. echocardiography revealed an oval mass located in the inferior wall of the left ventricle near the apex, and there was no finding of left ventricular hypertrophy. Computed tomography and magnetic resonance imaging, rather than echocardiography, were useful in determining the characteristics of the lipoma in this case. The tumor was resected by operation and the histology showed lipoma with no evidence of malignancy.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
