title: Prevention of left ventricular hypertrophy by ACE-inhibitor, ramipril in comparison with calcium-channel antagonist, felodipine.
abstract: This perspective study was performed to demonstrate the prevention of left ventricular hypertrophy by ACE-inhibitor, ramipril, in hypertensives of recent onset. Thirty-four hypertensive patients, treated with ramipril (group I), and 32 controls who received another frequently employed drug (the calcium channel-antagonist, felodipine (group II), were evaluated. Neither of two groups received any anti-hypertensive drug and did not suffer from left ventricular hypertrophy. All selected patients underwent M-mode echocardiography for measuring the following parameters: diastolic diameter of left ventricle, (DDLV); systolic diameter of left ventricle (SDLV); inter-ventricular septum (IVS); thickness of the posterior wall (PW); and left ventricular mass index (LVMI). Two anti-hypertensive drugs reduce systemic hypertension the same way. But, in hypertensives receiving ramipril (group I), the echocardiographic parameters of the left ventricle increased non-significantly. On the other hand, in those treated with felodipine (II group), these parameters significantly changed. The mechanisms of non-increase in cardiac and non-cardiac proteins, due to the ACE-inhibitors, are illustrated.
