[Structural and functional status of arteries in young and middle-aged men with ischemic heart disease].

Aim of the study was to determine whether structural and functional status of arteries differ between young and middle-aged men with ischemic heart disease (IHD). A total of 78 men aged 28 to 50 years were recruited in this study: 49 with angiographically proven obstructive atherosclerosis of coronary arteries, 29 without clinical manifestations of IHD (control group). Those with arterial hypertension, diabetes mellitus or marked hypercholesterolemia (LDL cholesterol more or equal 4.

[Increased erythrocyte membrane permeability to sodium--a risk factor for hypertension].

Monitoring the sodium-lithium counter transport, the authors examined the membrane permeability of red cells for sodium in 70 females and 127 males aged 20 to 70 years. In subjects with normal arterial pressure, the membrane permeability of the red cells showed no age-specific changes or differences in males and females at the age of 20 to 31 years and those over 40 years. Arterial hypertension (AH) according to the WHO criteria was diagnosed in 31% of those studied.
