Insights
Nebivolol significantly reduced left ventricular mass index (LVMI) more than ramipril in hypertensive patients. Both drugs effectively lowered blood pressure, but nebivolol demonstrated superior efficacy in reducing LVMI.
Area of Science:
- Cardiology
- Pharmacology
- Hypertension Management
Background:
- Left ventricular hypertrophy (LVH) is a significant risk factor for cardiovascular events in hypertensive patients.
- Nebivolol and ramipril are commonly prescribed antihypertensive medications with different mechanisms of action.
- Comparing their effects on LVH is crucial for optimizing treatment strategies.
Purpose of the Study:
- To compare the efficacy of nebivolol versus ramipril in reducing left ventricular mass index (LVMI) in patients with hypertension and LVH.
- To assess the impact of both drugs on blood pressure control.
Main Methods:
- A randomized, blinded endpoint (PROBE) study involving 106 patients with mild-to-moderate hypertension and LVH.
- Patients received either ramipril (2.5 mg/day) or nebivolol (5 mg/day) for 39 weeks.
- Left ventricular mass index (LVMI) was measured using echocardiography; blood pressure was monitored regularly.
Main Results:
- Both nebivolol and ramipril significantly reduced LVMI (p < 0.001).
- Nebivolol demonstrated a statistically significant greater reduction in LVMI compared to ramipril (p < 0.001).
- Both treatments achieved similar blood pressure reduction after 39 weeks.
Conclusions:
- Nebivolol and ramipril effectively decrease LVMI in hypertensive patients.
- Nebivolol (5 mg/day) is more effective than ramipril (2.5 mg/day) in reducing LVMI.
- Both drugs provide comparable blood pressure control.
Aims:
To compare the effects of nebivolol and ramipril on left ventricular hypertrophy in hypertensive patients.
Materials And Methods:
The study was conducted with a pre-randomised blinded endpoint (PROBE) design in which 106 patients with mild-to-moderate hypertension and left ventricular hypertrophy were randomised to ramipril (n = 52) or to nebivolol (n = 54) and treated for 39 weeks. The doses of ramipril and nebivolol were 2.5 and 5 mg/day, respectively. After 4-8 weeks, in patients with not normalised diastolic blood pressure, a thiazide diuretic was added (indapamide 2.5 mg or hydrochlorothiazide 12.5 mg/day). In the ramipril group, thiazide diuretic was added in 97% of subjects and in nebivolol group in 92%. The effect of treatment on left ventricular mass was assessed by two-dimensional guided M-mode transthoracic echocardiography, at baseline and at the end of the treatment. Left ventricular mass index (LVMI) was calculated and indexed to body surface area (g/m2) and height2.7 (g/height2.7). Blood pressure (BP) was measured at baseline, after 4, 8, 12, 24 and 39 weeks with a standard mercury sphygmomanometer.
Results:
Both left ventricular mass (LVM) and mass index (LVMI) decreased significantly after treatment with ramipril (LVMI -14.8 g/m2, -7.3 g/height2.7; p < 0.001), and after treatment with nebivolol (LVMI -31.9 g/m2, -15.6 g/height2.7; p < 0.001). The difference between ramipril and nebivolol (-17.1 g/m2, -8.3 g/height2.7) with regards to reduction of LVMI was statistically significant (p < 0.001). No differences were observed between the two groups in terms of normalization of LVMI. Both drugs decreased BP similarly after 39 weeks of treatment
Conclusions:
The present study shows that both nebivolol and ramipril decrease LVMI. Nebivolol 5 mg/daily treatment reduced LVMI significantly more than ramipril 2.5 mg/daily. Both drugs similarly decreased BP during the treatment.
