RESUMO
The relationship between lung cancer surgery and venous thromboembolism (VTE) in Japan has not been elucidated. This was a post hoc analysis of the Cancer-VTE Registry. The 1057 patients who underwent surgery for lung cancer were divided into the surgery alone (SA) group (n = 598) and the surgery plus chemotherapy (SC) group (n = 459), and the 1-year incidences of VTE and cerebral ischemia were analyzed. In the SA and SC groups, composite VTE was observed in one (0.2%) and 15 (3.3%) patients, respectively, and cerebral ischemia was observed in eight (1.3%) and four (0.9%) patients, respectively. Lymph node metastasis was more common in patients with D-dimer >1.2 µg/ml (odds ratio: 1.781, P = .004). SA had a low risk of VTE but a high risk of cerebral ischemia. Chemotherapy increases the risk of VTE. The D-dimer level was related to VTE and advanced cancer.
RESUMO
BACKGROUND: The D-dimer test is a simple test frequently used in routine clinical screening for venous thromboembolism (VTE). The Cancer-VTE Registry was a large-scale, multicenter, prospective, observational study in Japanese patients with cancer. This study aimed to clarify the relationship between D-dimer level at cancer diagnosis (baseline) and the incidence of events during cancer treatment (1-year follow-up period). METHODS: This was a post hoc sub-analysis of patients from the Cancer-VTE Registry whose D-dimer levels were measured at baseline. The incidence of events during the 1-year follow-up period was evaluated stratified by baseline D-dimer level. Adjusted hazard ratios for D-dimer level and events during the follow-up period were evaluated. RESULTS: Among the total enrolled patients, baseline D-dimer level was measured in 9020 patients. The mean ± standard deviation baseline D-dimer level was 1.57 ± 3.94 µg/mL. During the follow-up period, the incidence of VTE, cerebral infarction/transient ischemic attack (TIA)/systemic embolic events (SEE), bleeding, and all-cause death increased with increasing baseline D-dimer level. The incidence of all-cause death increased with increasing D-dimer level regardless of cancer stage. The adjusted hazard ratio of all-cause death was 1.03 (95% confidence interval: 1.02-1.03) per 1.0-µg/mL increase in baseline D-dimer level. CONCLUSIONS: Increases in D-dimer levels were associated with a higher risk of thrombotic events, such as VTE and cerebral infarction/TIA/SEE, during cancer treatment. Furthermore, higher D-dimer levels at cancer diagnosis were associated with a higher mortality rate, regardless of cancer stage.

Background: The relationships between frailty and clinical outcomes in elderly Japanese patients with non-valvular atrial fibrillation (NVAF) after catheter ablation (CA) have not been established. We evaluated the frailty rate of patients undergoing CA for NVAF, examined whether CA for NVAF improves frailty, and analyzed the CA outcomes of patients with and without frailty. Methods: Elderly Japanese patients (≥65 years; mean age: 72.8 years) who participated in the real-world ablation therapy with anti-coagulants in management of atrial fibrillation registry and who responded to the frailty screening index survey were included (n = 213). Frailty and AF recurrence were assessed preoperatively and at 3 and 6 months after CA. Results: Twenty-six patients (12.8%) were frail, 109 (53.7%) were pre-frail, and 68 (33.5%) were robust. Cardiovascular (frailty: 0.5%/person-year; pre-frailty: 0.1%/person-year; robust: 0.1%/person-year) and cardiac (frailty: 0.5%/person-year; pre-frailty: 0.1%/person-year; robust: 0.1%/person-year) events, as well as major bleeding (frailty: 0.3%/person-year; pre-frailty: 0.1%/person-year; robust: 0.1%/person-year), were numerically more frequent in the frailty group. No deaths from cardiovascular or stroke/systemic thromboembolic events occurred. A large proportion of patients did not experience 3-month (frailty: 96.2%; pre-frailty: 96.3%; robust: 88.2%) or 6-month (frailty: 88.5%; pre-frailty: 91.7%; robust: 86.8%) AF recurrence after CA. Weight loss, walking speed, and fatigue improved in the frailty and pre-frailty groups after CA. Conclusion: Japanese patients aged ≥65 years with frailty or pre-frailty had improved frailty screening index components, such as weight loss, walking speed and fatigue, after CA. Therefore, elderly patients with frailty or pre-frailty may benefit from CA for NVAF.
RESUMO
Real-world data on coronary events (CE) in elderly patients with atrial fibrillation (AF) are lacking in the direct oral anticoagulant era. This prespecified sub-analysis of the ANAFIE Registry, a prospective observational study in > 30,000 Japanese patients aged ≥ 75 years with non-valvular AF (NVAF), investigated CE incidence and risk factors. The incidence and risk factors for new-onset CE (a composite of myocardial infarction [MI] and cardiac intervention for coronary heart diseases other than MI), MI, and cardiac intervention for coronary heart diseases other than MI during the 2-year follow-up were assessed. Bleeding events in CE patients were also examined. Among 32,275 patients, the incidence rate per 100 patient-years was 0.48 (95% confidence interval (CI): 0.42-0.53) for CE during the 2-year follow-up, 0.20 (0.16-0.23) for MI, and 0.29 (0.25-0.33) for cardiac intervention for coronary heart diseases other than MI; that of stroke/systemic embolism was 1.62 (1.52-1.73). Patients with CE (n = 287) likely had lower creatinine clearance (CrCL) and higher CHADS2 and HAS-BLED scores than patients without CE (n = 31,988). Significant risk factors associated with new-onset CE were male sex, systolic blood pressure of ≥ 130 mmHg, diabetes mellitus (glycated hemoglobin ≥ 6.0%), CE history, antiplatelet agent use, and CrCL < 50 mL/min. Major bleeding incidence was significantly higher in patients with new-onset CE vs without CE (odds ratio [95% CI], 3.35 [2.06-5.43]). In elderly patients with NVAF, CE incidence was lower than stroke/systemic embolism incidence. New-onset CE (vs no CE) was associated with a higher incidence of major bleeding.Trial registration: UMIN000024006.

Background: The All Nippon Atrial Fibrillation In the Elderly Registry provides real-world insights into non-valvular atrial fibrillation (NVAF) in >30,000 elderly Japanese patients (aged ≥75 years), including >2,000 nonagenarians. We aimed to investigate outcomes in these patients by age and oral anticoagulant (OAC) type. Methods and Results: This prospective, multicenter, observational, cohort, 2-year follow-up study included elderly patients with NVAF who were able to attend hospital visits. The incidences of stroke/systemic embolic events (SEE), major bleeding, intracranial hemorrhage (ICH), cardiovascular death, all-cause death, and major adverse cardiovascular or neurological events (MACNE) were evaluated by age. Incidence rates increased significantly with age. Stroke/SEE, major bleeding, and ICH incidences plateaued in patients aged ≥90 years. Direct OACs (DOACs) yielded a numerically lower event incidence vs. warfarin in all age groups and endpoints, except for major bleeding in patients aged ≥90 years. DOACs (vs. warfarin) were significantly associated with a lower risk of stroke/SEE, major bleeding, and ICH in the ≥80-<85 years group, and reduced cardiovascular and all-cause death in the ≥75-<80 years group. In the ≥90 years subgroup, major bleeding history was a risk factor for all-cause death. Conclusions: Although DOAC vs. warfarin offers potential benefits for stroke prevention, limitations occurred in reducing major bleeding among those aged ≥90 years, indicating a potential benefit of very-low-dose DOAC for this demographic.
RESUMO
AIMS: Atrial fibrillation (AF) and heart failure (HF) often coexist. Older age is strongly associated with stroke, HF, and mortality. The association between coexistence of HF and a risk of clinical outcomes and the effectiveness of anticoagulation therapy including direct oral anticoagulants (DOACs) in elderly patients with AF and HF have not been investigated. We aimed to evaluate 2 years of outcomes and to elucidate the efficacy of DOACs or warfarin in elderly AF patients in the All Nippon AF In the Elderly (ANAFIE) Registry with and without a history of HF. METHODS AND RESULTS: The ANAFIE Registry is a multicentre, prospective observational study following elderly non-valvular AF patients aged ≥75 years for 2 years. Hazard ratios (HRs) were calculated based on the presence or absence of an HF diagnosis and DOAC or warfarin use at enrolment. Among 32 275 eligible patients, 12 116 (37.5%) had been diagnosed with HF. Patients with HF had significantly higher rates of HF hospitalization or cardiovascular death (HR 1.94, P < 0.001), cardiovascular events (HR 1.59, P < 0.001), cardiovascular death (HR 1.49, P < 0.001), all-cause death (HR 1.32, P < 0.001), and net clinical outcome including stroke/systemic embolism, major bleeding, and all-cause death (HR 1.23, P < 0.001), compared with those without HF; however, HRs for stroke/systemic embolism (HR 0.96, P = 0.56) and major bleeding (HR 1.14, P = 0.13) were similar. DOAC use was associated with a low risk of stroke/systemic embolism (HR 0.86, P = 0.19 in HF; HR 0.79, P = 0.016 in non-HF; P for interaction = 0.56), major bleeding (HR 0.71, P = 0.008 in HF; HR 0.75, P = 0.016 in non-HF; P for interaction = 0.74), HF hospitalization or cardiovascular death (HR 0.81, P < 0.001 in HF; HR 0.78, P < 0.001 in non-HF; P for interaction = 0.26), cardiovascular events (HR 0.83, P < 0.001 in HF; HR 0.82, P = 0.001 in non-HF; P for interaction = 0.65), cardiovascular death (HR 0.84, P = 0.12 in HF; HR 0.75, P = 0.035 in non-HF; P for interaction = 0.18), all-cause death (HR 0.89, P = 0.082 in HF; HR 0.80, P = 0.001 in non-HF; P for interaction = 0.091), and net clinical outcome (HR 0.88, P = 0.019 in HF; HR 0.81, P < 0.001 in non-HF; P for interaction = 0.21) compared with warfarin, irrespective of the presence or absence of HF. Analysis using the propensity score matching method showed similar associations. CONCLUSIONS: Non-valvular AF patients aged ≥75 years with a history of HF had higher risks of cardiovascular events and mortality. DOACs were favourable to warfarin regardless of the coexistence of HF. These results might encourage the use of DOACs in elderly patients with non-valvular AF with or without HF.

Gastrointestinal (GI) bleeding control is critical in elderly patients with atrial fibrillation (AF) receiving oral anticoagulants (OAC). This subgroup analysis aimed to clarify the actual state and significance of GI bleeding in elderly non-valvular AF (NVAF) patients. We evaluated the incidence and risk factors of GI bleeding during the 2-year follow-up and examined the GI bleeding impact on mortality. Of the 32,275 patients in the ANAFIE Registry, 1139 patients (3.5%) experienced GI bleeding (incidence rate, 1.92 events per 100 person-years; mean follow-up, 1.88 years); 339 upper and 760 lower GI bleeding events occurred. GI bleeding risk factors included age ≥ 85 years, body mass index ≥ 25.0 kg/m2, prior major bleeding, hyperuricaemia, heart failure, P-glycoprotein inhibitor use, GI disease, and polypharmacy (≥ 5 drugs). No significant differences in GI bleeding risk were found between direct OAC (DOAC) vs warfarin users (adjusted hazard ratios [95% confidence interval], 1.01 [0.88-1.15]). The 1-year post-GI bleeding mortality rate was numerically higher in patients with upper (19.6%) than lower GI bleeding (8.9%). In elderly Japanese NVAF patients, this large-scale study found no significant difference in GI bleeding risk between DOAC vs. warfarin users or 1-year mortality after upper or lower GI bleeding.
