Does one-month Global Longitudinal Strain (GLS) predict the development of pacing-induced left ventricular dysfunction (PIVD) or cardiomyopathy (PICMP) in patients following pacemaker implantation?
Global longitudinal strain measured one month post-pacemaker implantation can accurately predict the future development of pacing-induced left ventricular dysfunction before measurable changes in LVEF occur.
GLS is a novel predictor of decline in LV systolic function following pacemaker implantation, with the potential to identify patients at risk of PIVD before measurable changes in LVEF are apparent. GLS measured one month after implantation has high predictive accuracy for identifying patients who later develop PIVD or PICMP.
