经皮冠脉介入对冠心病合并左心衰竭患者治疗效果分析

Abstract: Objective To analyze the effect of percutaneous coronary intervention (PCI) on cardiac function and hemodynamics in patients with coronary artery disease complicated with left heart failure, and its safety. Methods From February 2023 to February 2024, 60 patients with coronary heart disease complicated with left heart failure were selected as the study subjects. The short-term efficacy was analyzed. Cardiac function and hemodynamic indicators were compared before and after treatment. The incidence of adverse cardiovascular events was calculated. Results After treatment, 22 cases showed significant improvement, 31 cases were effectively treated, and 7 cases experienced treatment failure, with a total effective rate of 88.33%. After treatment, left ventricular ejection fraction (LVEF), cardiac index (CI) and cardiac output (CO) were increased. Left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), mean pulmonary arterial pressure (mPAP) and systemic vascular resistance index (SVRI) were decreased (P＜0.05). Follow-up found 2 cases of angina pectoris, 1 case of myocardial infarction, 1 case of arrhythmia, and 2 cases of heart failure, totaling 6 cases. The total incidence was 10.00%. Conclusion PCI is effective to treat patients with coronary heart disease complicated with left heart failure achieving a satisfactory totol effective rate. It can significantly improve cardiac function and hemodynamics. Moreover, the incidence of adverse cardiovascular events is relatively low. It has important guiding significance for clinical practice.
