Abstract

Measurement of casual and near basal systolic and diastolic blood pressures were correlated with the severity of cardiorenal manifestations of hypertension in 471 patients. There was a significant association of each of the four blood pressure measurements with each other (P < 0.001). Systolic blood pressure and manifestations of hypertension increased with age. Blacks had higher blood pressures and more manifestations than whites. All four blood pressure measurements were significantly associated (r ≥ 0.78, P < 0.0005) with grade 3 fundi, proteinuria and casts in the urine, electrocardiographic left ventricular hypertrophy, cardiomegaly by chest X-ray and aortic dilatation and/or elongation by chest X-ray. The level of blood pressure is the important correlate of these manifestations of hypertension. This is equally true whether systolic, diastolic, casual or near basal measurements are used. Near basal blood pressure does not correlate better with the cardiorenal manifestations of hypertension than casual blood pressure, neither does diastolic blood pressure correlate better with these manifestations than systolic blood pressure.
