Abstract:

Objective This study investigated outcomes related to new onset different type of heart failure in patients with atrial fibrillation (AF). Methods This study was a retrospective observational study. The subjects were recruited from the People's Hospital of Xuancheng City from July 2017 to July 2020. All Patients with heart failure with reduced ejection fraction (HFrEF) or heart failure with mid-range ejection fraction (HFmrEF) were initially diagnosed. According to the result of AF, the patients were divided into four groups, HFrEF with AF (n=41),HFrEF with non- AF (n=59), HFmrEF with AF (n=58), HFmrEF with non- AF (n=35). The clinical characteristics and clinical adverse events of the 4 groups were compared.Multivariate Cox regression was used to analyze the effect of HFmrEF and HFrEF patients with AF on clinical adverse events. Results A total of 193 patients were selected. The mean follow-up time was (28.87±11.13) months. Among the four groups, the difference was statistically significant in the gender, age, uric acid, N-terminal pro-B-type natriuretic peptide (NT-proBNP), Left ventricular end diastolic diameter (LVEDD), left atrial diameter (LAD), left ventricular shortening score, CHA2DS2 - VASc score, New York heart association (NYHA), the utilization rate of β-blockers and diuretics, and the incidence of major adverse cardiovascular and cerebrovascular events (All P<0.05). Multiple Cox regression analysis shows that NYHA(HR=1.814,95%CI=1.051-3.131),NT-proBNP(HR=1.076,95%CI=1.033-1.120),CHA2DS2-VASc score(HR=1.375,95%CI=1.022-1.851),HFrEF with AF(HR=5.822,95%CI=1.699-19.955),HFmrEF with AF(HR=5.023,95%CI=1.565-16.118) were the influencing factors of main adverse cardiovascular and cerebrovascular events(All P<0.05). Kaplan-Meier analysis showed that the difference was a statistically significant in the incidence of long-term major adverse cardiovascular and cerebrovascular events among the four groups (χ2=12.432, P=0.006). Conclusion The initial patients with (HFrEF) or heart failure with mid-range ejection fraction (HFmrEF) combined AF were associated with increased risk of main adverse cardiovascular and cerebrovascular events.
