Enzyme assays of major blood lipid parameters detected no differences between peripheral venous blood specimens of normal subjects and functional cardiologic patients, nor between peripheral and central flow specimens of patients with neurocirculatory dystonia. Alpha cholesterol was typically decreased in all types of coronary disease, the decrease being particularly marked in central cardiac flow. Chronic coronary disease is associated with a rise of total cholesterol, its atherogenic fractions, the atherogenic coefficient and blood triglycerides, as compared to the respective parameters of functional cardiac patients. Acute and subacute coronary disease is associated with decreased blood lipid values, as compared to chronic coronary disease. Blood lipid phenotyping and secondary preventive procedures should rather be done in the absence of aggravations.

Correlations between coronary angiographic findings and the results of some noninvasive functional tests (electro- and echocardiography, bicycle ergometry, etc.) were examined in 50 patients. A relationship was established between the quantity of essentially (over 50% of the lumen) stenosed major coronary arteries and stress tolerance or the double product.

In 38 patients after myocardial infarction changes of the main parameters of the central haemodynamics have been found with the aid of tetrapolar transthoracic rheography and phonotachooscillography as compared with a control group (20 practically healthy individuals). A direct interrelationship has been found between the value of the stroke volume of the heart and individual tolerance to exercise as determined by bicycle ergometer. A regression equation was derived with which rough individual tolerance to exercise can be calculated by the value of the stroke volume. By the mathematical method of paired and multiple correlations the direct relationship of the value of the cardiac stroke volume with the degree of coronary and cardiac insufficiency has been found. The sequence of functional methods of examination and control at the sanatorium stage of rehabilitation of patients after myocardial infarction is discussed.
