Effect of aerobic exercise on mobilization and function of endothelial progenitor cells in patients with myocardial infarction
BACKGROUND:Exercise rehabilitation is an important means of non-drug treatment for patients with myocardial infarction.It can improve myocardial perfusion and cardiovascular function.The mechanism may be related to angiogenesis and repair mediated by vascular endothelial cells,while endothelial progenitor cells are the precursors of vascular endothelial cells.OBJECTIVE:To explore the impact of 12-week aerobic exercise on mobilization and function of endothelial progenitor cells in patients with myocardial infarction.METHODS:(1)A total of 66 patients with acute myocardial infarction who received percutaneous coronary intervention in First Affiliated Hospital of Zhengzhou University from January to October 2022 were selected and divided into exercise group(n=33)and control group(n=33)according to random number table method.Patients in the control group received conventional cardiac rehabilitation treatment for 12 weeks.Patients in the exercise group received conventional cardiac rehabilitation+12 weeks of aerobic exercise intervention.Cardiopulmonary fitness,New York Heart Association classification,left ventricular ejection fraction,serum troponin I,brain natriuretic peptide levels,and peripheral blood endothelial progenitor cells were measured before and 72 hours after intervention.(2)Endothelial cells were isolated from peripheral blood of the two groups of patients before intervention and 72 hours after intervention,and the proliferation,adhesion,and migration ability of endothelial cells were detected.RESULTS AND CONCLUSION:(1)At 72 hours after the intervention,New York Heart Association classification,serum troponin I and serum brain natriuretic peptide decreased(P<0.05);peak oxygen uptake,maximum power,completion time of incremental load test,and left ventricular ejection fraction at peak exercise increased(P<0.05);average heart rate and average subjective fatigue sensation score decreased(P<0.05);peripheral blood endothelial cell count increased(P<0.05)in the exercise group compared with those before intervention and the control group.(2)At 72 hours after intervention,the cell proliferation,adhesion,and migration ability of peripheral blood endothelial cells in the exercise group were higher than those before intervention and control group(P<0.05).(3)Regular aerobic exercise can promote mobilization of endothelial progenitor cells and enhance ability of proliferation,adhesion,and migration,thereby improving clinical condition,cardiac function,and cardiopulmonary fitness of patients with myocardial infarction.
