BackgroundAtrial fibrillation is associated with higher mortality. Identification of causes of death and contemporary risk factors for all‐cause mortality may guide interventions.Methods and ResultsIn the Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation (ROCKET AF) study, patients with nonvalvular atrial fibrillation were randomized to rivaroxaban or dose‐adjusted warfarin. Cox proportional hazards regression with backward elimination identified factors at randomization that were independently associated with all‐cause mortality in the 14 171 participants in the intention‐to‐treat population. The median age was 73 years, and the mean CHADS 2 score was 3.5. Over 1.9 years of median follow‐up, 1214 (8.6%) patients died. Kaplan–Meier mortality rates were 4.2% at 1 year and 8.9% at 2 years. The majority of classified deaths (1081) were cardiovascular (72%), whereas only 6% were nonhemorrhagic stroke or systemic embolism. No significant difference in all‐cause mortality was observed between the rivaroxaban and warfarin arms (P=0.15). Heart failure (hazard ratio 1.51, 95% CI 1.33–1.70, P<0.0001) and age ≥75 years (hazard ratio 1.69, 95% CI 1.51–1.90, P<0.0001) were associated with higher all‐cause mortality. Multiple additional characteristics were independently associated with higher mortality, with decreasing creatinine clearance, chronic obstructive pulmonary disease, male sex, peripheral vascular disease, and diabetes being among the most strongly associated (model C‐index 0.677).ConclusionsIn a large population of patients anticoagulated for nonvalvular atrial fibrillation, ≈7 in 10 deaths were cardiovascular, whereas <1 in 10 deaths were caused by nonhemorrhagic stroke or systemic embolism. Optimal prevention and treatment of heart failure, renal impairment, chronic obstructive pulmonary disease, and diabetes may improve survival.Clinical Trial Registration URL: https://www.clinicaltrials.gov/.

The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

We observed a higher incidence of early conduction disorders and need for PPM implantation after PAVR than generally reported after surgery. Whether this observation is clinically important requires larger prospective studies and follow up.

Aims:The aims of this study were to determine the appropriateness of permanent pacemaker implantation (PPI) after TAVI through an analysis of PM dependency at follow-up, and to assess long-term outcomes of patients undergoing PPI after TAVI.Methods and results: From June 2007 to February 2018, 1,116 consecutive patients without prior PM underwent TAVI in our institution. We assessed the incidence and predictors of PM dependency of patients who underwent PPI within 30 days, and also the six-year outcomes among patients who did not undergo PPI at 30 days. At 30 days, PPI was reported in 145 patients (13.0%). Rates of PM dependency were 35.7%, 35.8% and 33.3% at 1, 6 and 12 months, respectively. Analysing PPI timing, implantation on day 1 was found to be a predictor of PM dependency at six months (OR 20.7 [95% CI: 3.4-126.7]; p=0.001) and 12 months (OR 7.5 [95% CI: 1.4-40.2]; p=0.019). An interaction between PM dependency and the presence of baseline right bundle branch block (RBBB) at six months (p interaction =0.024) and 12 months (p interaction =0.028) was reported when PPI was performed on the same day as TAVI. At six years, patients who received a PM at 30 days showed a higher all-cause death rate (KM estimate 41.7% vs 57%; p log-rank =0.034).Conclusions: Among patients receiving PPI after TAVI, PM dependency rates were about 33-36% at one year. Patients with a baseline RBBB undergoing PPI at day 0 or at day 1 when severe CDs persisted for 24 hours after TAVI, irrespective of baseline CDs, had a higher chance of being PM-dependent at followups. Finally, PPI after TAVI was associated with increased six-year mortality.
