Abstract/OtherAbstract:
In the elderly, left ventricular hypertrophy (LVH) is a powerful risk factor for cardiovascular events and cardiovascular death. The purpose of the present study is to investigate the effect of long-term effective blood pressure control with the angiotensin-converting enzyme (ACE) inhibitor temocapril on left ventricular (LV) mass and function indices and the circulating concentration of the cardiac hormone brain natriuretic peptide (BNP) in elderly hypertensives with LVH. Temocapril treatment was administered for 1 year to 11 elderly hypertensives (mean age, 72 years) with LVH. Cardiac dimensions and circulating concentrations of BNP were monitored before initiation of treatment and after 1 year of treatment. At entry, BNP levels were positively correlated with the LV mass index, but were not correlated with the mean blood pressure, LV ejection fraction, or E/A ratio (the ratio of peak transmitral flow velocity in early diastole, peak E, to that in late diastole, peak A). After 1 year, temocapril treatment resulted in effective control of blood pressure. The treatment did not affect the LV ejection fraction, but modestly increased the E/A ratio. Temocapril significantly reduced septal and posterior wall thickness and the LV mass index. BNP significantly declined after 1 year. Changes in BNP were significantly related to changes in the LV mass index, but were not related to changes in the mean blood pressure, LV ejection fraction, or E/A ratio. The results suggest that long-term ACE inhibitor treatment with temocapril can induce the regression of LV mass and reduce elevated plasma BNP in elderly hypertensive patients with LVH. In this study, changes in BNP reflected the magnitude of regression of LVH.
