RESUMO
There is limited evidence demonstrating whether cannabis, cocaine, amphetamine, or other stimulants use contributes to heart failure (HF) readmissions. We used the National Readmissions Database years 2016-2018 to identify patients with HF with and without substance use disorder (SUD) (defined as a composite of cannabis, cocaine, or other stimulant use disorders). The main outcome was to assess the risk of 30-day readmissions in HF patients with and without SUD. Of 978,217 HF hospitalizations that met the inclusion criteria, 34,717 (3.5%) had concomitant SUD. HF patients with SUD had significantly higher hazard for 30-day all-cause readmissions (adjusted hazard ratio [aHR] 1.16 [1.12-1.21]; P < 0.01) compared to HF patients without SUD. In conclusion, HF patients with SUD have an elevated risk of 30-day all-cause readmissions, mainly driven by cocaine and other stimulant disorders. Screening for substance use in hospitalized HF patients as well as timely referral for treatment are important to prevent HF readmissions.

The prevalence of diabetes mellitus (DM) in hospitalized heart failure (HF) patients is increasing over time. However, the effect of DM on short-term readmissions for HF is not well established. We investigated the effects of DM on readmissions of HF patients. All adult hospitalizations with a primary diagnosis of HF were identified in the National Readmission Database (NRD) for 2018 and were categorized into those with and without a secondary diagnosis of DM. The primary outcome was to assess risk difference in 30 and 90-day all-cause readmissions. Multivariate Cox survival analysis and multivariate Cox regression were performed to estimate the readmission risk difference in HF patients with and without DM. Of 925,637 HF hospitalizations that met the inclusion criteria, 441,295 (47.6%) had concomitant DM. Diabetics hospitalized for HF had higher prevalence of obesity (37.3% vs 19.5%), kidney disease (58.4% vs 29.2%) and coronary disease (61.1% vs 51.0%), compared to HF hospitalizations without DM. In adjusted analyses, DM was associated with higher hazards for all-cause [hazards ratio (HR), 30 days: 1.04 (1.02-1.06); 90 days: 1.07 (1.05-1.09)], HF [HR, 30 days: 1.05 (1.02-1.07); 90 days: 1.08 (1.05-1.10)] and myocardial infarction (MI) [HR, 30 days: 1.26 (1.12-1.41); 90 days: 1.38 (1.25-1.52)] readmissions. In conclusion, in patients with HF-related hospitalizations, the presence of DM was associated with a higher risk of 30 and 90-day all-cause, HF and MI readmissions.
