However, in this population the relationship between other baseline echocardiographic parameters and the development of post\u2010pacing cardiomyopathy (PPCMP) remains poorly defined.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n To identify preimplant echocardiographic parameters associated with the development of PPCMP in patients with normal LVEF undergoing DCPM implantation for AV block.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Among 140 consecutive patients who underwent DCPM implant for AV block between January 1st 2016 and December 31st, 2019, data from 111 patients with available follow\u2010up through December 31, 2024, was retrospectively analyzed. PPCMP was defined as a 10% reduction in LVEF and\/or absolute LVEF\u2009<\u200950% with an average ventricular pacing burden of \u2265\u200920%.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Of 140 patients, 111 with complete data were included (mean age: 76\u2009\u00b1\u200910 years; 55% male and 88% white). Preimplant LVEF was 61\u2009\u00b1\u20094% with echocardiogram performed 2(0\u201326) days before DCPM implant. Over a mean follow\u2010up of 4\u2009\u00b1\u20092.3 years, 46 patients (41%) developed PPCMP (LVEF%: 45[35\u201350] vs 62[58\u201364];\n p<\/jats:italic>\n \u2009<\u20090.001). Preimplant left atrial (LA) dimension (cm; 4.3[3.8\u20134.5] vs 3.8[3.5\u20134.3];\n p<\/jats:italic>\n \u2009=\u20090.03) and LA dimension index (mL\/m\n 2<\/jats:sup>\n ; 38\u2009\u00b1\u200912 vs 32\u2009\u00b1\u200911;\n p<\/jats:italic>\n \u2009=\u20090.008) were larger in patients who developed PPCMP. Among PPCMP patients, LVEF reduction correlated inversely with mitral annular septal and lateral E\/e\u2032 ratios (\n r<\/jats:italic>\n \u2009=\u2009\u22120.33,\n p<\/jats:italic>\n \u2009=\u20090.03 and\n r<\/jats:italic>\n \u2009=\u2009\u22120.34,\n p<\/jats:italic>\n \u2009=\u20090.04, respectively), early diastolic mitral inflow velocity (\n r<\/jats:italic>\n \u2009=\u2009\u22120.34,\n p<\/jats:italic>\n \u2009=\u20090.02) and LA size (\n r<\/jats:italic>\n \u2009=\u2009\u22120.35,\n p<\/jats:italic>\n \u2009=\u20090.01). Larger LA size also correlated with higher E\/e\u2032 ratios (\n r<\/jats:italic>\n \u2009=\u20090.4,\n p<\/jats:italic>\n \u2009<\u20090.02) but not with history of AF, HTN, obesity and mitral valve disease. In multivariable regression analyses, each 1\u2010cm increase in LA size was associated with a 5.54\u2010fold higher hazard of first heart failure (HF) admission (Cox,\n p<\/jats:italic>\n \u2009=\u20090.0008) and a\u2009~125% increase in total HF admissions (Poisson,\n p<\/jats:italic>\n \u2009=\u20090.006) during the study period.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Among patients with normal LV systolic function undergoing DCPM for AV block, pre\u2010existing LV diastolic dysfunction, reflected by larger LA size, elevated E\/e\u2032 ratios, and higher early diastolic mitral inflow velocity, is strongly associated with development of PPCMP. Preimplant recognition of these parameters may help identify patients who would benefit from upfront biventricular or conduction system pacing to mitigate the risk of PPCMP.<\/jats:p>\n
