Abstract
This case-control study was aimed at evaluating the distribution of some echocardiographic signs of cardiac organ damages in elderly patients with white coat hypertension (WCH), as compared with a normotensive group of elderly. Correlations between the signs of cardiac organ damages and the clinical and ambulatory blood pressure parameters (obtained by means of a 24-h monitoring) have also been evaluated. The first screening covered 258 elderly subjects of both sexes, aged from 65 to 82 years, with clinical diagnosis of hypertension (systolic and diastolic blood pressures being higher than 160 and 95 mmHg, respectively). Of this group, 116 subjects remained in the final pool, and their echocardiographic parameters were compared with 33 normotensive (N) subjects. Out of the 116 clinically hypertensive patients, 29 (25%) displayed WCH, according to the established criteria. Variance analyses on the ranks followed by Dunn's test revealed no statistically significant differences between the N and WCH groups, while the hypertensive group (H) proved to be significantly different from both the N and the WCH groups. In addition to the descriptive statistics, an analysis of correlations between the pressure variables and the echocardiog...Continue Reading
