The National Heart, Lung, and Blood Institute is currently sponsoring a multicenter clinical trial to evaluate the long-term efficacy of partial ileal bypass in the prevention of recurrent myocardial infarction in hypercholesterolemia patients. Thus we felt that a report of our clinical results with this intervention at the Montreal Heart Institute during the last 11 years would be of interest. Twenty patients with type II hyperlipoproteinemia and a mean age of 38 (range 25-54) years underwent partial ileal bypass between March 1971 and April 1978. This intervention was associated with aortocoronary bypass surgery in 11 patients. All patients were followed at regular intervals. The mean survival time was 70.7 (range 1-123) months. Two deaths were observed during follow-up, one from an acute myocardial infarction and the other from ventricular fibrillation, respectively, 1 month and 1 and one-half years after partial ileal bypass. The ileal bypass was undone twice because of gastrointestinal problems including a malabsorption syndrome and repeated episodes of subocclusion. A progressive decrease of the effects of the operation on serum cholesterol was noted, from a 33 per cent reduction at 3 months to 43 per cent at 2 years and 16 per cent at 6 years. Two patients presented an acute myocardial infarction respectively 3 and 4 years after the operation, respectively, and one patient suffered a right-sided hemiplegia at age 30, 12 months after the operation. Of 14 patients with angina pectoris preoperatively (class III in 10), eight remained symptomatic postoperatively (class I and II angina in five).(ABSTRACT TRUNCATED AT 250 WORDS)

A 62-year old patient with a history of chronic anemia associated with malabsorption secondary to short gut syndrome, experienced acute chest pain the second hour after the transfusion of a crossmatch-compatible erythrocyte suspension. His electrocardiogram (ECG) revealed widespread ST-segment depressions and he had an elevated troponin level. Laboratory findings and physical examination did not indicate the presence of immunological or non-immunological blood transfusion reactions. Cardiac catheterization was performed and showed angiographically non-obstructive, atherosclerotic plaques and the absence of vasospasm or thrombus formation. Following antiischemic therapy his symptoms resolved completely. The ECG obtained 24 hours after the emergence of chest pain demonstrated normal sinus rhythm with no ST-T wave changes. We present a rare case of acute myocardial infarction induced following a blood transfusion. To the best of our knowledge, a few cases of acute myocardial infarction associated with blood transfusion have been formally recorded in the medical literature and the clinical experience regarding such cases is indeed quite limited. The present case is reviewed in the context of the relevant literature as a practical resource for clinical practice.
