Background: The aim of this study was to examine the incidence of cardiac complications in patients with hypertrophic cardiomyopathy (HCM) during noncardiac surgery. Methods: A retrospective study was made for surgical patients in the period of 1989-2000 at Kitasato University Hospital. Results: Thirty out of 66000 patients were preoperatively diagnosed as HCM. Sixty percent of the HCM patients had one or more perioperative cardiovascular complications. There were perioperative congestive heart failure in 3 patients (10%), and myocardial ischemia in 4 patients (13%). However, there were no myocardial infarction, no life-threatening dysarrhythmia and no cardiac death. Factors which appeared to be associated with the perioperative cardiovascular complications were the type of HCM (HOCM), major surgery, general anesthesia and preoperative medication with a beta-blocker or a calcium channel blocker. Conclusions: It is suggested that patients with HCM undergoing noncardiac surgery have a high incidence of cardiac complications such as congestive heart failure and myocardial ischemia.
