Objective  To explore the effect of cardiac rehabilitation strategy on myocardial enzymes and ventricular remodeling in patients with coronary heart disease.

  Methods  A total of 146 patients with coronary heart disease who were treated in our hospital were enrolled. According to the random number table method, the patients were randomly divided into control group(n=68) and rehabilitation group(n=78). The control group implemented routine nursing measures and the rehabilitation group implemented cardiac rehabilitation strategy. Lactate dehydrogenase (LDH), creatine kinase (CK), α-hydroxybutyrate dehydrogenase (HBDH), creatine kinase isoenzymes (CK-MB), glutamic-oxalacetic transamin (AST) levels, cardiac index (CI), cardiac output (CO), and left ventricular ejection fraction (LVEF) and ventricular remodeling were compared and analyzed.

  Results  After nursing, the levels of LDH, CK, HBDH, CK-MB and AST in the rehabilitation group were significantly lower than those in the control group (P < 0.05); before treatment, there were no significant differences in CI, CO and LVEF between the two groups(P>0.05); after nursing, the CI, CO and LVEF of the rehabilitation group were significantly higher than the control group(P < 0.05); after nursing, the incidence of angina pectoris, arrhythmia and ST segment changes, and expansion of infarct size in the rehabilitation group were significantly lower than that of the control group(P < 0.05).

  Conclusion  Cardiac rehabilitation strategy for patients with coronary heart disease can reduce myocardial enzyme levels and control the development of ventricular remodeling.
