Flow chart of the study. A total of 190 patients with hypertension were enrolled and their blood pressure, cardiac function, brain DWI and blood biochemical indicators were determined. The CI group (92 cases) and non-CI group (98 cases) were divided according to their brain DWI results. The left ventricular diastolic function of 190 patients was measured. There were 4 cases with normal left ventricular diastolic function and 88 cases with abnormal left ventricular diastolic function in the CI group. In the non-CI group, there were 14 cases with normal left ventricular diastolic function and 84 cases with abnormal left ventricular diastolic function. The data were collected, statistical analysis was performed and final conclusions were drawn. DWI, diffusion-weighted imaging; CI, cerebral infarction; IVRT, isovolumic relaxation time; Ea/Aa, peak flow velocity of the left atrioventricular annulus at the early stage of filling/peak flow velocity of the left atrioventricular annulus at the late stage of filling; A'value, atrial tissue velocity of the left atrioventricular valve annulus.
