Obesity (BMI >30 kg/m2) was associated with significantly higher odds of 30-day readmission (OR 1.775) compared to non-obese patients hospitalized with heart failure.

Does obesity increase 30-day readmissions, in-hospital mortality, and the use of NIPPV in hospitalized heart failure patients?
In hospitalized heart failure patients, obesity (BMI >30 kg/m²) is an independent risk factor for 30-day readmissions and increased requirement for noninvasive positive pressure ventilation.
Effect estimate: OR 1.775 (95% CI 1.33-2.37)
Absolute Event Rate: 44% vs 30.7%
p-value: p=0.0001
The prevalence of heart failure (HF) is on the rise; currently, it affects around five million people in the United States (US) and the prevalence is expected to rise from 2.42% in 2012 to 2.97% in 2030. HF is a leading cause of hospitalizations and readmissions, accounting for a major economic burden to the US healthcare system. Obesity is a widely accepted risk factor of HF; however, data regarding its independent association with HF mortality and morbidity is heterogeneous. Globally, more than two-thirds of deaths attributable to high body mass index (BMI) are due to cardiovascular diseases (CVD). This study aimed to investigate the potential role of obesity (BMI >30 Kg/m 2 ) in HF patients in terms of 30-day readmissions, in-hospital mortality, and the use of noninvasive positive pressure ventilation (NIPPV).
Mughal et al. (2021) conducted an observational in Heart Failure (n=800). Obesity (BMI >30 kg/m2) vs. Non-obese (BMI <30 kg/m2) was evaluated on 30-day readmission (OR 1.775, 95% CI 1.33-2.37, p=0.0001). Obesity (BMI >30 kg/m2) was associated with significantly higher odds of 30-day readmission (OR 1.775) compared to non-obese patients hospitalized with heart failure.
