Analysis Of Clinical Related Factors Of Arrhythmia In Elderly Patients With Acute And Chronic Myocardial Ischemia

Objective:The relationship between the two types of arrhythmia and the number of vascular lesions,serum BNP,serum potassium concentration,left ventricular end diastolic diameter and left ventricular ejection fraction were analyzed in elderly patients with acute and chronic myocardial ischemia.Methods:634 cases of elderly patients with coronary heart disease diagnosed by clinical symptoms and coronary angiography were older than 60 years old,,according to the clinical manifestations and auxiliary examination results,acute coronary syndrome(ACS)and chronic ischemic syndrome(CIS)were divided into two groups,Record the 24-hour ambulatory electrocardiogram changes(Holter)clear 24 hours occurred in the type of arrhythmia.The relationship between the type of supraventricular and ventricular arrhythmia and the number of vascular lesions,serum potassium concentration,serum BNP value,left ventricular ejection fraction and left ventricular end diastolic diameter were analyzed.Results:1.Elderly ACS group and elderly CIS arrhythmia types: ACS group and CIS arrhythmia types: a total of 476 patients with ACS group,among them,the atrial premature beats(APB)were 114 cases,atrial tachycardia(AT)were 38 cases,and 110 cases were atrial fibrillation(AF).Ventricular premature beats(VPB)were 138 cases,ventricular tachycardia(VT)were 34 cases,ventricular fibrillation(VF)were 12 cases.158 CIS patients,APB were18 cases,AT were 8cases,46 cases were AF,VBP were 62 cases,VT were 22 cases,VF were 2cases.2.Elderly ACS group arrhythmia types and influence factors: the type of arrhythmia associated with potassium levels,hypokalemia,the high incidence of ventricular arrhythmia(67.80%,P < 0.05).As lesion count increases,the incidence of arrhythmia.BNP increased,decreased LVEF and LVDD bigger,Atrial arrhyttmia incidence of arrhythmia was obviously higher than that of ventricular arrhythmias,but the differences were not statistically significant(P > 0.05).3.Old CIS group arrhythmia types and influence factors: arrhythmia types and elevated serum BNP levels,increased left ventricular ejection fraction and left ventricular end-diastolic diameter increased,and the difference was statistically significant(P < 0.05);But can be found when single lesion vessels,higher the incidence of arrhythmia;And when potassium lower atrial arrhythmia significantly higher incidence of ventricular arrhythmias.Conclusion:1.In elderly patients with ACS,hypokalemia easy occurrence of ventricular arrhythmia,cardiac arrhythmia occurred types and elevated serum BNP levels,increased left ventricular ejection fraction and left ventricular end-diastolic diameter increases.2.In elderly patients with CIS,when the serum BNP levels,increased left ventricular ejection fraction and left ventricular end-diastolic diameter increase easy occurrence of ventricular arrhythmia,cardiac arrhythmia occurred type has nothing to do with coronary lesion count and potassium level.3.In elderly patients with ACS,along with the lesion blood vessel counts increase,the incidence of arrhythmia increases,then the hypokalemia easy occurrence of ventricular arrhythmia,decreasing and elevated BNP,LVEF and LVDD increases prone to the atrial arrhythmia.4.In elderly patients with CIS,single vascular lesions,the high incidence of arrhythmia,hypokalemia,which is easy to occur atrial arrhythmia,and elevated BNP,decreased LVEF and LVDD increases when the easy occurrence of ventricular arrhythmia...
