Table 4.

Primary and secondary outcomes by history of AF in those assigned to CRT (n=2642).

Outcome	Total events	Events / history of AF	Events / No AF	HR (history of AF/No AF)	95% Credible interval	Posterior probability
Time to all-cause mortality or HFH	689	164	525	1.43	1.15 – 1.78	0.007
Time to all-cause mortality	353	93	260	1.45	1.09 – 1.99	0.013

The hazard rate for each outcome in patients with history of AF compared to no history of AF in those assigned to CRT (n=2642). All models are adjusted for age, sex, NYHA class, ejection fraction, QRS width, presence of LBBB, diabetes, hypertension, ischemic etiology, use of antiarrhythmic drugs, use of beta-blockers, use of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker, and the presence of an ICD. AF: atrial fibrillation, CRT: cardiac resynchronization therapy, HFH: heart failure hospitalization, HR: hazard ratio.
