Abstract：Objective To explore the effect of enhanced external counterpulsation(EECP)on ser-um vascular endothelial growth factor(VEGF)level and cardiopulmonary function in patients with stable angina pectoris(SAP).Methods A prospective double-blind controlled trial was con-ducted on 300 SAP patients admitted to Departments of Cardiovascular Medicine and Geriatrics of Jincheng People's Hospital from January 2021 to December 2023.They were randomly divided in-to study group(150 cases)and control group(150 cases).Coronary angiography or coronary CT angiography indicated that there were 101,101 and 98 cases,respectively,of one-,two-and three-vessel diseases.The patients of both groups were given conventional drug therapy(secondary pre-ventive drug for coronary heart disease),and those of the study group received EECP therapy ad-ditionally.The changes in serum VEGF level and related indicators of cardiopulmonary exercise test before and after one course of standardized treatment(36 h)were observed and compared be-tween the two groups.Results The VEGF level was significantly higher in the patients with three-vessel disease than those with two-and one-vessel diseases(P＜0.05).The level was obvi-ously increased in the study group and control group after intervention than before(238.41±82.57 ng/L vs 218.75±82.58 ng/L,224.47±85.08 ng/L vs 218.96±83.04 ng/L,P＜0.01),and the former group obtained better improvement of VEGF than the latter group(P＜0.01).The level in the study group and the control group with one-,two-and three-vessel lesions was notably higher than those before intervention(P＜0.05,P＜0.01).The study group with one-,two-and three-vessel lesions had statistical differences in the VEGF level after intervention when compared with that in the control group(P＜0.01).The levels of Peak VO2/kg and VO2/kg@AT were sig-nificantly increased in both groups after intervention than before(P＜0.01),with those of the study group notably higher than those of the control group[19.87±5.18 ml/(kg·min)vs 17.15±5.18 ml/(kg·min),P＜0.01;14.33±2.24 ml/(kg·min)vs 12.81±1.57 ml/(kg·min),P＜0.01].Conclusion EECP treatment is helpful to increase VEGF level and improve cardiopul-monary function in SAP patients.
