| Abstract | ||||
| Іntroductіon: Hypertension is a leading cause of stroke, coronary artery disease, heart failure and premature death around the world. Ambulatory blood pressure monitoring (ABPM) calculates the average of BP readings over a set period of time, and its values have been proven to be more closely related to the left ventricular mass (LVM) . Aіm:This study aimed at finding ambulatory Blood pressure thresholds at which Echocardiographic indices of Left Ventricle Size and function start to be affected .Matеrіal & Mеthods. This study was conducted on seventy eight patients visiting cardiology clinic of Suez Canal hospital . Rеsults.This cross-sectional study included 78 patients , the mean age was 55 years( from 21 to 70 years). Subjects with significantly higher systolic BP averages found with dilated left atrium , significant higher average SBP found with impaired GLS compared with those with normal SBP readings who were found to have normal GLS . There was a strong correlations between ambulatory BP readings and Echocardiographic changes including LVH , Left atrial dilatation and impaired GLS , correlations were more stronger in GLS impairment rather than LVH and LA dilatation (correlation coefficient: 0.772,P<0.001). Systolic blood pressure averages showed stronger correlations with LVH, LA dilatation and GLS impairment than diastolic averages . The determined optimal ABPM threshold in this study at which cardiac changes (LVH, LA dilatation or GLS impairment) occur is > 140 mmHg for 24-hour SBP. Conclusіon. Higher ambulatory BP thrersholds were significantly associated with hypertension, LA dilatation, LV hypertrophy and impaired GLS in subjects with normal LVEF. The thresholds at which these cardiac changes start to manifest are higher than the established ABPM normal values, which was found to be > 140 mmHg in 24-SBP. | ||||
