Abstract:
BACKGROUND: Systemic hypertension produces varying degree of LVH which is associated with increased cardiovascular morbidiity. Previous studies have documented regression of LVH with various antihypertensives including calcium channel blockers, except diuretics and vasodilators. Recently echocadiographic assessment of the change of left ventricular mass(LVM) after antihyertensive therapy have been reported to offer prognostic cardiovascular information. The aim of this echocardiographic study is determining the influence of nicardipine, a calcium channel blocker, on the change of LVM in patients with essential hypertenison. METHODS: Left ventricular mass(LVM) and left ventricular mass index(LVMI) were measured by M-mode echocardiography in 15 patients with essential hypertension. Nicardipine, a calcium channel blocker, was administered for 6 months and two echocardiographies were done before and after administering, respectively. RESULTS: In the 15 patients treated for 6 months, systolic and diastolic pressure remained very significantly decreased compared with pressure before before therapy(135+/-15mmHg vs 168+/-26mmHg, and 86+/-7mmHg vs 105+/-16mmHg, both p<0.01). Concomitantly both LVM and LVMI decreased significantly(209+/-49g vs 235+/-71g, and 116+/-6g/m2 vs 131+/-38g/m2,both p<0.05). And no change was noted in left ventricular cavity size, demonstration that LVM reduction was due to regression of hypertrophy. CONCLUSION: This study showed that nicardipine produced a significant decrease in blood pressure, LVM, and LVMI over the 6 months period. And large and longterm controlled studies are needed for the clarification of the association between nicardipine and regression of LVH in hypertensive patients.
