Body mass index, regional adipose deposition, and clinical outcomes in non-ischaemic dilated cardiomyopathy: a prospective cohort study
To assess the relationship between body mass index (BMI), regional fat distribution, and clinical outcomes, specifically all-cause mortality and heart transplantation, in patients with non-ischaemic dilated cardiomyopathy (DCM).
Key Findings:
Lower BMI and reduced regional adipose tissue are associated with worse clinical outcomes in DCM patients, with specific hazard ratios indicating the strength of these associations.
Epicardial adipose tissue (EAT) volume is a strong independent predictor of heart failure death/heart transplantation, with a C-index of 0.70.
Body mass index is the best predictor of arrhythmia endpoints, with a C-index of 0.64.
Interpretation:
Patients with lower BMI and thinner regional fat around the heart exhibited worse cardiac function and higher rates of adverse clinical outcomes, including mortality and heart transplantation, highlighting the need for targeted interventions.
Limitations:
The study is limited to non-ischaemic DCM patients, which may not generalize to other heart failure populations, and the exclusion of patients with significant coronary artery disease may affect the applicability of findings.
Potential biases or confounding factors in the study design could influence the results.
Conclusion:
The findings highlight the importance of BMI and regional fat distribution in predicting clinical outcomes in DCM, suggesting that targeted interventions may be beneficial for patients with lower BMI and reduced adipose tissue, and future research should explore these interventions.
