Automatic resting blood pressure determinations were made in a darkened sound proof room at 6- to 8-week intervals for approximately 1 year in 50 patients with ischemic heart disease and 40 controls of comparable ages. Analysis was made of systolic and diastolic blood pressure means and ranges over all visits with respect to clinical group, and age and sex. In the controls, average systolic pressures and ranges increased with age. In the patients, systolic pressure means and ranges also increased with age, but for the middleaged and elderly groups, they were on the average at definitely higher levels than the corresponding controls. Diastolic pressure means were essentially the same for the controls at all ages, but at a higher average level at all three age periods for the patients. Diastolic pressure ranges were higher for the patients at all age levels. For both controls and patients, the systolic and diastolic pressures were lower for females in the young group, but higher for females over 50 years of age. Female controls and patients had wider systolic and diastolic mean ranges than did male controls and male patients. It is concluded that the resting behavior of the vascular system, as reflected in the level and variability of blood pressure, is different for the majority of the patients with coronary artery disease in this study, compared to their controls.

    Endothelin-B receptors (ETBR), located mainly on endothelial cells, produce vasodilator effects by releasing either nitric oxide (NO) and/or prostacyclin (PGI2). Several reports have suggested impaired endothelial NO production in Dahl salt-sensitive (DS) rats. This impaired NO production...
