    OBJECTIVE: After MI pathological LV remodeling is one of the major causes of death. We previously showed the NO mediated beneficial effects of nebivolol in rat MI model, in this study we aimed to evaluate the NOS related mechanisms in this phenomenon

    THE SHORT-TERM EFFECTS OF CILAZAPRIL ON LEFT-VENTRICULAR DIASTOLIC FUNCTION

    To investigate the short-term effects of cilazapril on left ventricular diastolic functions in patients with essential hypertension, 20 patients with mild-to-moderate essential hypertension were evaluated. Following 2 weeks of placebo washout, all patients underwent blood pressure determination and echo-Doppler ultrasonography recordings. Cilazapril, 2.5 mg, was given to all patients, and blood pressure was determined. Echo Doppler ultrasonography recordings were repeated 3 h after drug therapy. The investigated diastolic function parameters were peak and mean velocities of mitral E and A waves, ratio of peak E to peak A, and acceleration and deceleration rates of E and A waves. Both systolic and diastolic blood pressure changes were insignificant. The E wave peak and mean velocities were significantly increased (p = 0.006 and 0.02, respectively), and the A wave peak and mean velocities were significantly reduced (p = 0.006 and 0.02, respectively) after cilazapril therapy. The ratio of peak E to peak A velocity was also found to be increased following cilazapril therapy (p = 0.006). It is to be concluded that the immediate improvement of left ventricular diastolic functions after cilazapril therapy despite the lack of blood pressure decrease is probably a result of the inhibition of tissue angiotensin-converting enzyme and/or other local humoral factors, but this needs to be further investigated
