Key result
Obesity increases the risk of sudden cardiac death through structural, electrical, and metabolic remodeling, though the specific impact of weight reduction on this risk remains unclear.
Why the study?
Although obesity is closely linked to sudden cardiac death, the underlying mechanisms remain incompletely understood, and it is unknown whether weight loss decreases sudden cardiac death risk.
This review highlights the multifaceted pathophysiological mechanisms linking obesity to sudden cardiac death, emphasizing the need for prospective trials to evaluate weight management interventions.
Weight reduction should not yet change sudden cardiac death prevention practice; leaves open its impact on obesity-driven remodeling.
Obesity and sudden cardiac death (SCD) share common risk factors. Obesity, in and of itself, can result in the development of SCD. Numerous epidemiologic and clinical studies have demonstrated the close relationships between obesity and SCD, however, the underlying mechanisms remain incompletely understood. Various evidences support the significance of excess adiposity in determining the risk of SCD, including anatomical remodeling, electrical remodeling, metabolic dysfunction, autonomic imbalance. Weight reduction has improved obesity related comorbidities, and reversed abnormal cardiac remodeling. Indeed, it is still unknown whether weight loss contributes to decreased risk of SCD. Further high-quality, prospective trials are needed to strengthen our understanding on weight management and SCD.

Yao et al. (2022) conducted a review in Obesity and Sudden Cardiac Death. Obesity vs. Normal weight was evaluated. Obesity increases the risk of sudden cardiac death through structural, electrical, and metabolic remodeling, though the specific impact of weight reduction on this risk remains unclear.
