88 Chapter 6 AF has hemodynamic consequences which resulted in lower ejection fractions and higher NT pro BNP levels. Additionally, AF patients performed worse on the 6-minutes walking test (64.6 vs. 74.7% of predicted, p=0.10). The most common cause of AF in the general population is hypertension and atrial dilatation (LAVI). In this study, a borderline significant association was found between LAVI and AF (p=0.10). However, when combining this factor with a radiation dose parameter in the multivariate regression analyses, both parameters became statistically significant (p=0.02) with a high AUC (0.93).
