Home Blood Pressure Can Predict the Risk for Stroke/Bleeding Events in Elderly Patients With Nonvalvular Atrial Fibrillation From the ANAFIE Registry.

ABSTRACT:

Background

Blood pressure (BP) fluctuates significantly in patients with atrial fibrillation (AF); office BP measurements seem insufficient to assess AF patient risk accurately. We hypothesized that home BP could better predict the risk of stroke/systemic embolic events (SEE) and major bleeding in patients with AF than office BP.

Methods

In this prespecified subcohort study of the ANAFIE (All Nippon AF in the Elderly) Registry, we evaluated the impact of home BP on the risk of stroke/SEE, major bleeding, intracranial hemorrhage, all-cause death, and net cardiovascular outcome (a composite of stroke/SEE and major bleeding). At enrollment, home BP was measured twice in the morning and evening for 7 days.

Results

In total, 4933 elderly patients (aged ≥75 years) with nonvalvular AF participated. Incidences of net cardiovascular outcome, stroke/SEE, major bleeding, and intracranial hemorrhage increased significantly with increasing home systolic BP (H-SBP). Compared with H-SBP <125 mm Hg, ≥145 mm Hg was associated with increased risk of these events. The association between H-SBP and the events was observed only in patients with ≥20 H-SBP measurements.

Conclusions

In elderly patients with nonvalvular AF, high H-SBP (≥145 mm Hg) was a significant predictor of stroke/SEE, major bleeding, and intracranial hemorrhage risk. Strict BP control guided by the increasing number of home BP measurements may provide an accurate clinical outcome risk assessment.

Project description:BackgroundWe determined the long-term event incidence among elderly patients with nonvalvular atrial fibrillation in terms of history of stroke/transient ischemic attack (TIA) and oral anticoagulation.MethodsPatients aged ≥75 years with documented nonvalvular atrial fibrillation enrolled in the prospective, multicenter, observational All Nippon Atrial Fibrillation in the Elderly Registry between October 2016 and January 2018 were divided into 2 groups according to history of stroke/TIA. The primary end point was the occurrence of stroke/systemic embolism within 2 years, and secondary end points were major bleeding and all-cause death within 2 years. Cox models were used to determine whether there was a difference in the hazard of each end point in patients with/without history of stroke/TIA, and in ischemic stroke/TIA survivors taking direct oral anticoagulants versus those taking warfarin.ResultsOf 32 275 evaluable patients (13 793 women [42.7%]; median age, 81.0 years), 7304 (22.6%) had a history of stroke/TIA. The patients with previous stroke/TIA were more likely to be male and older and had higher hazard rates of stroke/systemic embolism (adjusted hazard ratio, 2.25 [95% CI, 1.97-2.58]), major bleeding (1.25, 1.05-1.49), and all-cause death (1.13, 1.02-1.24) than the other groups. Of 6446 patients with prior ischemic stroke/TIA, 4393 (68.2%) were taking direct oral anticoagulants and 1668 (25.9%) were taking warfarin at enrollment. The risk of stroke/systemic embolism was comparable between these 2 groups (adjusted hazard ratio, 0.90 [95% CI, 0.71-1.14]), while the risk of major bleeding (0.67, 0.48-0.94), intracranial hemorrhage (0.57, 0.39-0.85), and cardiovascular death (0.71, 0.51-0.99) was lower among those taking direct oral anticoagulants.ConclusionsPatients aged ≥75 years with nonvalvular atrial fibrillation and previous stroke/TIA more commonly had subsequent ischemic and hemorrhagic events than those without previous stroke/TIA. Among patients with previous ischemic stroke/TIA, the risk of hemorrhagic events was lower in patients taking direct oral anticoagulants compared with warfarin.RegistrationURL: https://www.Clinicaltrialsgov; Unique Identifier: UMIN000024006.

Project description:BackgroundAdvancing age, decreasing renal function, and atrial fibrillation are strongly associated. Real-world evidence of direct oral anticoagulant (DOAC) use among elderly patients ≥75 years of age with nonvalvular atrial fibrillation and renal dysfunction is limited.ObjectivesThis study sought to assess 2-year outcomes and anticoagulant treatment, stratified by renal function.MethodsEnrolled patients were divided into 4 subgroups by creatinine clearance (CrCl) to determine the impact of renal dysfunction on clinical outcomes.ResultsOf 32,275 patients, 26,202 with CrCl data were analyzed (median follow-up 2.00 [IQR: 1.92-2.00] years); 1.3% of patients had CrCl <15 mL/min, 10.7% had CrCl 15 to <30 mL/min, 33.4% had CrCl 30 to <50 mL/min, 35.8% had CrCl ≥50 mL/min, and 18.9% had unknown CrCl. Cumulative incidences of stroke/systemic embolic events, major bleeding, major plus clinically relevant nonmajor bleeding, cardiovascular death, all-cause death, and net clinical outcomes increased with decreasing CrCl. In multivariable Cox regression analysis, lower CrCl emerged as an independent risk factor for these clinical outcomes, except for major bleeding, compared with CrCl ≥50 mL/min. The effectiveness and safety of DOACs over warfarin were similar or better across 3 CrCl subgroups with CrCl 15 mL/min or more. DOAC use was associated with a lower risk of stroke/systemic embolic events, major bleeding, cardiovascular death, all-cause death, and net clinical outcome compared with warfarin in patients with CrCl 30 to <50 mL/min.ConclusionsIncidences of major clinical outcomes increased with decreasing renal function in elderly nonvalvular atrial fibrillation patients. DOACs were effective and safe even in patients with renal dysfunction (CrCl 15-<50 mL/min).

Project description:Background and aimsElderly patients with nonvalvular atrial fibrillation (NVAF) might have a higher risk of intracerebral hemorrhage. To investigate this, we compared the incidence of intracranial hemorrhage (ICH) and its subtypes, as well as ischemic stroke, in patients taking direct oral anticoagulants (DOACs) compared with warfarin in a real-world setting. We also determined the baseline characteristics associated with both ICH and ischemic stroke.MethodsPatients aged ⩾ 75 years with documented NVAF enrolled in the prospective, multicenter, observational All Nippon Atrial Fibrillation in the Elderly Registry between October 2016 and January 2018 were evaluated. The co-primary endpoints were the incidence of ischemic stroke and ICH. Secondary endpoints included subtypes of ICH.ResultsOf 32,275 patients (13,793 women; median age, 81.0 years) analyzed, 21,585 (66.9%) were taking DOACs and 8233 (25.5%) were taking warfarin. During the median 1.88-year follow-up, 743 patients (1.24/100 person-years) developed ischemic stroke and 453 (0.75/100 person-years) developed ICH (intracerebral hemorrhage, 189; subarachnoid hemorrhage, 72; subdural/epidural hemorrhage, 190; unknown subtype, 2). The incidence of ischemic stroke (adjusted hazard ratio (aHR) 0.82, 95% confidence interval (CI) 0.70-0.97), ICH (aHR 0.68, 95% CI 0.55-0.83), and subdural/epidural hemorrhage (aHR 0.53, 95% CI 0.39-0.72) was lower in DOAC users versus warfarin users. The incidence of fatal ICH and fatal subarachnoid hemorrhage was also lower in DOAC users versus warfarin users. Several baseline characteristics other than anticoagulants were also associated with the incidence of the endpoints. Of these, history of cerebrovascular disease (aHR 2.39, 95% CI 2.05-2.78), persistent NVAF, (aHR 1.90, 95% CI 1.53-2.36), and long-standing persistent/permanent NVAF (aHR 1.92, 95% CI 1.60-2.30) was strongly associated with ischemic stroke; severe hepatic disease (aHR 2.67, 95% CI 1.46-4.88) was strongly associated with overall ICH; and history of fall within 1 year was strongly associated with both overall ICH (aHR 2.29, 95% CI 1.76-2.97) and subdural/epidural hemorrhage (aHR 2.90, 95% CI 1.99-4.23).ConclusionPatients aged ⩾ 75 years with NVAF taking DOACs had lower risks of ischemic stroke, ICH, and subdural/epidural hemorrhage than those taking warfarin. Fall was strongly associated with the risks of intracranial and subdural/epidural hemorrhage.Data access statementThe individual de-identified participant data and study protocol will be shared for up to 36 months after the publication of the article.

Project description:The real-world status of proton pump inhibitor (PPI) use in patients with atrial fibrillation (AF) receiving antithrombotic treatment is largely unknown. The All Nippon AF In the Elderly (ANAFIE) Registry, a prospective, multicenter, observational study, aimed to determine treatment patterns, risk factors, and outcomes among elderly (aged ≥75 years) Japanese non-valvular AF (NVAF) patients in the real-world clinical setting. The present subanalysis of the ANAFIE Registry determined the PPI prescription status of 32,490 elderly Japanese NVAF patients. Patients were stratified by PPI use (PPI+) or no PPI use (PPI-). Risk scores for stroke (CHADS2, CHA2DS2-VASc) and bleeding (HAS-BLED), anticoagulant use, time in therapeutic range (TTR) for warfarin, and anticoagulant/antiplatelet combination use were evaluated. PPIs were used in 11,981 (36.9%) patients. Compared with the PPI- group, the PPI+ group included a greater proportion of female patients (45.2% vs 41.3%; P <0.0001) and had significantly higher CHADS2, CHA2DS2-VASc, and HAS-BLED scores (P <0.0001 for each) as well as higher prevalences of several comorbidities. In the PPI+ group, 54.6% of patients did not have gastrointestinal (GI) disorders and were likely prescribed a PPI to prevent GI bleeding events. Most of the patients with a GI disorder in the PPI+ group had reflux esophagitis. Compared with patients not receiving anticoagulants, a significantly higher proportion of patients receiving anticoagulants received PPIs. For patients receiving anticoagulants, antiplatelet drugs, and both drugs, rates of PPI use were 34.1%, 44.1%, and 53.5%, respectively (P <0.01). Although the rate of PPI use was the highest for NVAF patients receiving both antiplatelet and anticoagulants, no clear differences were observed in the anticoagulants used. These data suggest that PPIs were actively prescribed in high-risk cases and may have been used to prevent GI bleeding among elderly NVAF patients receiving antithrombotic drugs.
