Abstract
Fifty-seven patients with grade 1 essential hypertension concurrent with chronic obstructive bronchitis or bronchial asthma were examined. They were found to have characteristics of the daily blood pressure profile, such as a high load due to pressure and its inadequate nocturnal lowering. The concentric type of left ventricular hypertrophy (LVH) is typical of the vast majority of persons of this category. The patients with a high LVH concentricity have more significant imbalance of autonomic cardiac rhythm regulation with the preponderance of myocardial sympathetic impact while those with low LVH concentricity showed higher aldosterone secretion.
