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.
