Overall 210 patients aged 60-74 years suffering from coronary heart disease associated with chronic circulatory failure, stages I, IIA and IIB, 53 patients aged 45-59 years and 20 healthy persons aged 45-74 years were examined for the renin-angiotensin-aldosterone system and antidiuretic hormone. Renin activity, the concentration of aldosterone and vasopressin in blood plasma were investigated by radioimmunoassay. In the initial stage of heart failure, the elderly persons showed up more marked renin activation in blood plasma, followed by its lowering as decompensation progressed as well as an increase in the concentration of aldosterone and vasopressin, which resulted in the progress of circulatory failure.
