The hemodynamic effects of coffee in cardiac disease have not been fully evaluated. Ten patients with cardiac disease and five normals underwent cardiac catheterization. Hemodynamic measurements were obtained prior to and 20 minutes after the oral ingestion of coffee containing 158 mg of caffeine, with coffee, all of the normal patients demonstrated a rise in the cardiac index and stroke index. Coffee produced in the patients with cardiac disease only minimal changes in these measurements. The cardiac rate, systemic blood pressure, pulmonary artery pressure and left ventricular end diastolic pressure were essentially unchanged in both groups, Small amounts of coffee can be safely taken by patients with cardiac disease.
