Demographic and Electrocardiographic Predictors
The risk of PPMI after TAVR increased with age (OR 1.15, 95% CI 1.01-1.32; p = 0.04; I2 = 89%), with history of diabetes mellitus (OR 1.08, 95% CI 1.03-1.11; p < 0.01; I2 = 0%) and occurred with greater incidence in males compared to females (OR 1.29, 95% CI 1.23-1.35; p = <0.01; I2 = 0%). History of hypertension, COPD, past aortic valve procedure, or prior PCI and Logistic EuroSCORE were not found to be statistically significant predictors. In terms of ECG, presence of RBBB (OR 5.62, 95% CI 3.9-8.10; p < 0.01; I2 = 82%), baseline AVB (OR 1.75, 95% CI 1.08-2.84; p = 0.02; I2 = 91%) and LAFB (OR 1.88, 95% CI 1.14-3.11; p = 0.01; I2 = 7%) were significantly associated with PPMI. No difference of risk was identified for patients with AF, LBBB, baseline IVCD or change in QRS duration following procedure.
