Figure 1: Study subjects depicting inclusion and exclusion criteria.

Figure 2: Survival without ventricular arrhythmia (VA) KM curves according to heart failure medications dose (> or ≤ median dose), showing significantly less VA among patients taking > median dose of beta adrenergic blockers, with no significant impact of angiotensin antagonists or mineralocorticoid receptor blockers medication dosages on VA occurrence. P<0.05 is considered significant.

Figure 3: Overall survival KM curves according to heart failure medication treatment (regardless of dose) revealing reduced mortality in patients treated with angiotensin antagonists. P<0.05 is considered significant.

Figure 4: Survival KM curves according to presence or absence of VA, as a time dependent covariate. Occurrence of VA had a significant impact, increasing overall mortality. P<0.05 is considered significant.
