Clinical Effect of Coronary Internal Grinding in the Treatment of Stable Angina Pectoris with Anterior Descending Branch Calcification
Objective:To investigate the clinical effect of coronary internal grinding in the treatment of stable angina pectoris with anterior descending branch calcification.Method:A total of 90 patients with anterior descending branch calcification of stable angina pectoris treated in the First Hospital of Longyan from January 2021 to February 2023 were retrospectively selected,and divided into two groups according to different treatment plans.45 patients were included in the control group by balloon dilation plus stent implantation,and 45 patients were included in the observation group by coronary internal grinding based on the treatment of the control group.The operative effect,cardiac function changes and recurrent angina pectoris were compared between the two groups.Result:Compared with the control group,the observation group had a larger minimum lumen diameter and a lower rate of heaviest stenosis,the differences were statistically significant(P<0.05).At 6 months after operation,compared with control group,left ventricular ejection fraction was higher and left ventricular end-diastolic diameter was lower in observation group,the differences were statistically significant(P<0.05).The recurrence rate of angina pectoris in the observation group was lower than that in the control group with in one year after operation,and the difference was statistically significant(P<0.05).Conclusion:The application of coronary internal grinding in patients with stable anterior descending branch calcification of angina pectoris can significantly improve the cardiac function of patients,improve the operative effect,reduce the recurrence rate of angina.
