Abstract [en]

OBJECTIVE: To study the cross-sectional relationship between circulating angiotensin converting enzyme (ACE) activity and echocardiographically determined left ventricular geometry in a study of 380 70-year-old men participating in a health-survey reexamination and 50 patients with hypertension.

METHODS: Two-dimensional guided M-mode and Doppler echocardiography. Fluorometric assay of serum ACE activity.

RESULTS: The serum ACE activity was higher in the elderly men with left ventricular concentric hypertrophy than it was in men with normal geometry and left ventricular eccentric hypertrophy (32, 27, and 26 U/l, respectively, P < 0.01 for both comparisons before and after adjustment for the 24 h mean arterial pressure, body mass index, and use of antihypertensive medication). The serum ACE activity correlated with the thickness of the left ventricular interventricular septum (r = 0.12, P = 0.0095), the left ventricular relative wall thickness (r = 0.13, P = 0.0053 ), and the total peripheral resistance (r = 0.16, P = 0.0034), but not with the left ventricular mass (r = -0.039, P = 0.45) of these elderly men. The serum ACE activity in the hypertensive patients also correlated with the left ventricular interventricular septum thickness (r = 0.34, P = 0.020) independently of the 24 h mean arterial blood pressure, age, sex, body mass index, and insulin sensitivity.

CONCLUSION: Levels of serum ACE activity are associated with left ventricular geometry.
