Abstract

Oxygen consumption was measured in 500 patients (151 F, 349 M, ages 12–84 yr.) undergoing routine cardiac catheterization. Sex, age, and heart rate were found to be the strongest predictors of oxygen consumption index (OCI). Males had higher OCI values than females at any age. Older patients of both sexes had lower OCI values than younger patients. Heart rate correlated directly with OCI. Treatment with pro‐pranolol correlated inversely with OCI. However, after correction for heart rate, there were no significant differences in OCI values between propranolol treated and non‐treated patients. A linear regression equation was developed using combinations of variables to predict OCI, and tables are presented for predicting OCI in those patients in whom this variable cannot be directly measured.
