Abstract:
To evaluate the effects of diltiazem hydrochloride (D) and verapamil (V) on hypertensive left ventricular (LV) diastolic function, the measurement of pulsed Doppler transmittal inflow was performed in 44 patients (22 cases in each group) before, and at 3 h and 7 h after single large dose. Sixteen patients of D group and 11 of V group received routine dose for one month. The Doppler diastolic function indexes included EDC EV/AV, EA/TA AA/TA and 1/3 FFd. The result showed that blood pressure was reduced to the same level in two groups, but improvement of LV diastolic function was more significant in D group. It is concluded that two calcium antagonists can improvement of LV diastolic function after single large dose, but improvement of LV diastolic function is not completely related to reduction of Hood pressure. After one month, since D can reduce Wood pressure and improve mycardial ischemia more markedly than V, and the negative inotropic effect is lower than V, D is superior to V in improving LV diastolie function
