Patients with Atrial Fibrillation in Clinical Practice: Comorbidity, Drug Treatment and Outcomes (Data from RECVASA Registries)

Abstract

Aim. To study comorbidity, drug therapy and outcomes in patients with atrial fibrillation (AF) included in the outpatient and hospital RECVASA registries. Material and methods. Patients with AF (n=3169; age 70.9±10.7 years; 43.1% of men) in whom comorbidity, drug therapy, short-term and longterm outcomes (follow-up period from 2 to 6 years) were included in hospital registers RECVASA AF (Moscow, Kursk, Tula), as well as outpatient registers RECVASA (Ryazan) and RECVASA AF-Yaroslavl. Results. Outpatient registries (n=934), as compared to hospital registries (n=2235), had a higher average age of patients (73.4±10.9 vs 69.9±10.5; p2DS₂-VASc 4.65±1.58 vs 4.15±1.71; pConclusion. The majority of patients with AF registries in 5 regions of Russia had a combination of three or more cardiovascular diseases (73.9%), as well as chronic non-cardiac diseases (68.8%). The frequency of proper cardiovascular pharmacotherapy was insufficient (68.6%), especially at the outpatient stage (55.6%). Over the observation period (2-6 years), the average mortality per year was 10.3%, but at the same time it differed significantly in the regions (from 3.7% in Moscow to 9.7-12.5% in Yaroslavl, Ryazan and Kursk). Cardiovascular causes of deaths occurred in 62%. A higher risk of death (1.5-2.7 times) was associated with a history of stroke and MI, diabetes mellitus, COPD, heart rate>80 bpm, systolic blood pressure <110 mm Hg, decreased hemoglobin level. However, the risk of death decreased by 1.2-2.4 times in cases of prescription of anticoagulants, ACE inhibitors / ARBs, beta-blockers and statins. The risk of ACVA and MI was the highest in the presence of the history of this event (2.7 and 2.6 times, respectively). Anticoagulant prescription was significantly associated with a reduced risk of stroke in women.
