Results

3,237 patients from 63 institutions in the Tokyo area being treated with any of 4 DOACs (n=1,676) or warfarin (n=1,561) were followed-up (median of 39.3 months). There were no significant differences in rates of stroke, major bleeding, and all-cause mortality for DOAC vs. warfarin users. Under propensity score matching, the incidence of stroke and all-cause death remained equivalent, but the incidence of major bleeding was significantly lower among DOAC than warfarin users.

Baseline Characteristics

We conducted our first analysis of the registry data, and although we found equivalent mean age between the DOAC and warfarin users (71.8+/-9.5 vs.72.3+/-9.4 years, p=0.2117), we found a slightly lower risk of stroke (CHADS2 score of 0 or 1 [46.9% vs. 39.4%, p<0.0001]) and significantly better creatinine clearance in DOAC users (70.4+/-27 vs. 65.6+/-25.7 mL/min, p<0.0001). Importantly, we documented under-dosing in 32% of warfarin users and inappropriate-low-dosing in 19.7-27.6% of DOAC users.

Participant flow

The SAKURA AF registry enrolled 3267 AF patients treated by warfarin or NOACs from 63 institutions. The patient's registration was finished on December 31, 2015.
the follow-up was ended in December 31, 2018.

Adverse events

Stroke/TIA: DOAC 1.2 vs. warfarin 1.8%/year

Major bleeding: DOAC 0.5 vs. warfarin 1.2%/year

Death: DOAC 2.1 vs. warfarin 1.7%/year

Outcome measures

Primary effectiveness endpoint: stroke/TIA
Primary safety endpoint: Major bleeding,
Secondary endpoint: death, CV events
