Investigation And Analysis Of Sudden Cardiac Death In 96 Patients With Coronary Heart Disease After Percutaneous Coronary Intervention

Objective This study calculated the incidence of sudden cardiac death after percutaneous coronary intervention in patients with coronary atherosclerosis in Gansu Province,and analyzed the risk factors of sudden cardiac death.To provide more theoretical basis for the prevention and long-term treatment of high-risk groups of sudden cardiac death.Methods The patients who had successfully performed percutaneous coronary intervention in Gansu Provincial People’s Hospital from January 1,2012 to December 31,2018 were selected as the subjects and the number of cases of sudden cardiac death were obtained.The sudden death cases were included into the sudden cardiac death group,and the corresponding number was set as the control group after matching the age,gender,residence and other factors.we analyzed The cause of death,type of primary coronary heart disease,season and time period of sudden cardiac death group.Finally,we compared the basic medical history,biochemical parameters,echocardiography,number of coronary artery lesions and routine medication history of the two groups,and determined the incidence and high risk factors of sudden cardiac death after PCI.Results The incidence of sudden cardiac death after percutaneous coronary intervention in Gansu area was 1.7%.Most of the sudden cardiac death occurred in winter(December to February)and time period(06:00-11:59).Fatigue is the most common cause of sudden cardiac death and acute myocardial infarction is the main cause of primary coronary heart disease.By comparing the two groups,smoking history,diabetes history,irregular medication,cholesterol,triglyceride,low density lipoprotein,high density lipoprotein,LVEF < 40% and Ventricular aneurysm in sudden cardiac death group were higher than those in non death group(P < 0.05).Multivariate regression analysis showed that history of diabetes,homocysteine,cholesterol,low density lipoprotein,LVEF < 40% and ventricular aneurysm were risk factors for SCD.Conclusion The incidence of sudden cardiac death in patients with coronary heart disease after percutaneous coronary intervention is high in Gansu area.For the high risk group of sudden cardiac death,medical staff,patients,family members and communities should pay more attention to and prevent them in advance.
