| Popis: | One hundred seventy-six unmedicated mildly hypertensive subjects (113 men, 63 women) underwent M-mode echocardiography to determine left ventricular mass (LVM) and relative wall thickness (RWT), 24-h ambulatory blood pressure monitoring, and completed standardized questionnaires measuring marital and job stress. Subjects were aged 46 ± 9 years old; 45.4% had daytime diastolic blood pressure < 90 mm Hg; 96.1% of LVM results were in the normal range. We found that neither marital distress nor job strain was a determinant of LVM. However, a segmental regression approach revealed inflection points of 131 mm Hg systolic daytime blood pressure and 83 and 87 mm Hg nighttime diastolic blood pressure in the relation between LVM and RWT, respectively, and ambulatory BP. In addition, we found that the variability of LVM was best explained by indexing LVM by height, rather than body surface area. |
