The incidence of perioperative myocardial infarction with transurethral resection of the prostate.

We performed a prospective study of 250 men undergoing transurethral resection of the prostate to determine the incidence of perioperative myocardial infarction. The prevalence of coronary artery disease in the study group was 27%. Patients had measurement of total creatine kinase and its MB isoenzyme and electrocardiography preoperatively and on the first three postoperative days. Only one myocardial infarction was diagnosed, an incidence rate of 0.4%. The overall rate of serious post-operative complications was 3.6%. No deaths occurred during the operative hospitalization. We conclude that with transurethral resection perioperative myocardial infarction is a rare event despite the high prevalence of coronary artery disease in this surgical population. Routine postoperative surveillance with electrocardiograms and creatine kinase determinations in asymptomatic patients is not warranted.
