A review of the electrocardiograms (ECG) of 108 patients with sickle cell anemia found only 3 with patterns consistent with myocardial infarction. Two of the 3 patients with ECG infarct patterns had postmortem examination confirmation of the infarction. These two patients had no significant coronary atherosclerosis nor did the other six autopsied patients in the present series. Literature reports of postmortem examinations on patients with sickle cell anemia confirm the scarcity of coronary atherosclerosis and myocardial infarction in these patients. Forty of the 108 ECGs showed signs of left ventricular hypertrophy and 20 others had nondiagnostic ST and T wave abnormalities. Nine showed first degree AV block and four right bundle branch block.
