Objective To discuss the feasibility and safety of left bundle branch area pacing(LBBaP)in aged patients.Methods The patients with bradyarrhythmia(n=174)undergone LBBaP were retrospectively analyzed in Central Hospital of Ma`anshan City.All patients were divided,according to their age,into aged group(age>80)and younger group(60<age<80).The clinical baseline materials,indexes related to surgery,pacemaker parameters during surgery and after follow-up for 1 y,echocardiographic parameters and complications were compared between 2 groups.The feasibility and safety of LBBaP were observed in aged patients.Results Among 185 patients,there were 174 had successful LBBaP and success rate was 94.1%.The success rate in aged group was similar to that in younger group(93%vs.94%,P=0.805),and pacemaker parameters during surgery had no statistical difference between 2 groups(P>0.05).The average age and percentages of complications including diabetes,coronary heart disease,abnormal renal function and heart failure were higher in aged group than those in younger group(P>0.05).After followed up for 1 y,the threshold and perception increased(P<0.05)and impedance decreased(P=0.034)in aged group during surgery,and perception increased(P=0.001)and impedance decreased(P<0.001)in younger group during surgery.The left ventricular ejection fraction(LVEF)increased in 2 groups than before surgery(P<0.05),which was more significant in aged group(P=0.008).The level of N-terminal pro-brain natriuretic peptide(NT-proBNP)decreased significantly in 2 group than before surgery(P<0.001).The pacing parameters remained stable,tricuspid regurgitation had no development in 2 groups,and complication had no statistical difference between 2 groups.Conclusion LBBaP is a safe and effective physiological pacing method for aged patients.
