LEFT-VENTRICULAR PERFORMANCE IN PATIENTS WITH NORMAL CORONARY-ARTERIES - HEMODYNAMIC CHARACTERISTICS AND CLINICAL FOLLOW-UP

Of 111 patients with normal coronary angiograms, 68 patients had eleva ted left-ventricular end diastolic pressure and 'low-normal' ejection fraction (Group I) while the other 43 patients had normal left ventric ular end diastolic pressure and 'high normal' ejection fractions (Grou p II). Although the number of patients was too small for meaningful st atistical analysis, systematically a higher percentage of patients wit h diabetes mellitus, hypertension, hypercholesterolemia and smoking hi story was found in Group I. In contrast to the patients in Group II, p atients in Group I tended to have more angina and ischemic events.
