[Effect of physical loading on serum enzyme activity in post-myocardial infarct patients].
The study of patterns of serum AST, ALT, CPK, LDH, and glycogen phosphorylase (GP) activity following bicycle ergometry in 26 male patients 1 to 1.5 months after myocardial infarction demonstrated no increase in AST, ALT and CPK activity, whereas total LDH activity was increased, with a tendency to elevated LDH-1 and LDH-2 fractions, as compared to the baseline, in those cases where exercise was discontinued because of ST depression. Patients with favorable response to bicycle ergometry that continued until the submaximum heart rate for a given age was achieved showed a tendency to elevated LDH-5 that may be a physiological response to exercise. The demonstrated increase in total GP activity, both in patients with exercise-induced ST depression and in those with elevated ST from the leads corresponding to the site of myocardial infarction, may reflect stress-induced reversible ischemia.
