Coronary Vasodilator Capacity and Hypertension-Induced Increase in Left Ventricular Mass

64 untreated middle-aged hypertensive patients without significant coronary artery stenosis and 14 normotensive volunteers comparable for age and gender (Total n=78).

Normotensive volunteers (n=14) and hypertensive patients with appropriate left ventricular mass (n=33).

Coronary vasodilator capacity (minimum coronary resistance), left ventricular wall mechanics (midwall shortening), and diastolic filling pattern (ratio of peak early and peak late velocities of transmitral flow).surrogate
