[Effectiveness of the physical training of post-myocardial infarction patients with differing exertion tolerances]. / Ob effektivnosti fizicheskikh trenirovok perenesshikh infarkt miokarda bol'nykh s razlichnoi tolerantnost'iu k nagruzke.

A total of 159 men after myocardial infarction were examined. Of them 73 were engaged in physical training for 11 mos. Its efficacy was analysed after the results of bicycle ergometry taking account of initial exercise tolerance. A positive effect of physical training was noted both in the patients with high and low exercise tolerance. Raised physical working capacity was observed in parallel with the improved indices of the left ventricular contractility in accordance with the results of two-dimensional echocardiography. The authors also observed a favorable effect of physical training on lipoprotein metabolism, in particular a decrease in the value of the apo B/apo AI ratio was noted that might suggest a decrease in the inflow of cholesterol to the vascular wall and an enhanced outflow from it.

[Serum apolipoproteins A-1 and B in young males with a history of myocardial infarction]. / Apoproteiny A1 i B plazmy krovi u molodykh muzhchin, perenesshikh infarkt miokarda.

The content of the protein-lipid components of lipoproteins of individual classes was studied in 87 coronary heart disease patients surviving myocardial infarction under 40 years of age. All the patients lived in Sverdlovsk. The control group was made up of 49 age-matched males without any symptoms of CHD. CHD patients aged 30-39 years showed a number of differences as compared to healthy men; these included elevated plasma levels of cholesterol, triglycerides and low-density lipoprotein cholesterol as well as an increase in the apoprotein B levels and the apo-B/apo-A1 ratio. In a group of CHD patients aged 20-29 years enhanced plasma concentrations of apo-B and an increase in the apo-B/apo-A1 ratio, the latter approaching 1 were the only change in the lipoprotein system as against control.
