The Effect of Percutaneous Coronary Intervention in Elderly Patients with Coronary Heart Disease and Its Impact on Cardiac Function Indicators

Abstract

Objective: To analyze the role of percutaneous coronary intervention and its value in elderly patients with coronary heart disease. Methods: A total of 88 elderly patients diagnosed with coronary heart disease between June 2022 and June 2023 were recruited and divided into two groups using the random number table method, with 44 cases in each group. The control group received conventional drug therapy, while the observation group received percutaneous arterial interventional treatment in addition to conventional drug therapy. Clinical efficacy, adverse cardiovascular events, cardiac function indicators, and quality of life were observed in both groups. Results: The observation group demonstrated a significantly higher total effective rate and significantly lower adverse cardiovascular events (P < 0.05). Furthermore, after treatment, the observation group showed a higher left ventricular ejection fraction, as well as lower left ventricular end-systolic diameter, left ventricular end-systolic volume, left ventricular end-diastolic diameter, and left ventricular end-diastolic volume (P < 0.05). Additionally, the observation group had higher scores in all eight dimensions of the SF-36 scale (P < 0.05). Conclusion: For elderly patients diagnosed with coronary heart disease, percutaneous coronary intervention can achieve superior clinical efficacy and high safety and can help improve cardiac function indicators and quality of life.
