Abstract：Objective： To investigate the effect of 24-hour ambulatory blood pressure loading value on cardiac contraction and relaxation function of essential hypertensive patient.Methods： Select 80 essential hypertensive patients. Use 24-hour ambulatory blood pressure monitoring and echocardiogram monitor cardiac function, and the dynamics index:left ventricular ejection fraction(LVEF), left ventricular peak filling rate(PFR), left ventricular peak ejection rate (PER), and the ratios (EV/AV) of mitral blood flow relaxation early velocity (EV) to left atrium contraction flow velocity (AV). According to the blood pressure loading value ＜30% and ＞30%，the patients are divided into 4 teams:A,B,C, and D, compare their cardiac function's deference.Results： To compare A with B,PFR is obviously different; To compare A with C,D separately, LVEF and EV/AV are greatly different(P＜0.05)；and PFR differ sharply (P＜0.01);To compare C with D, LVEF, PER, PFR, and EV/AV has no obvious difference. Conclusion： The rising blood pressure loading value both systolic and diastolic can make greatly effect on ventricular diastolic function， and the second one is more obviously. At the same time, diastolic pressure loading value correlated obviously with ventricular contraction function, so it can be used as sensitive index to prognosticate the cardiac function change of the patient who has this disease.
