Why the study?
Increased body weight and obesity may be linked to higher arrhythmic risk, prompting evaluation of obesity's impact on arrhythmias, hospitalization, and death in patients with an ICD for primary or secondary prevention.
Does obesity affect the risk of arrhythmic events and survival in patients with an implantable cardioverter defibrillator?
Does obesity affect the risk of arrhythmic events and survival in patients with an implantable cardioverter defibrillator?
In patients with an ICD, obesity was paradoxically associated with a lower risk of ventricular tachycardia and a trend toward lower all-cause and cardiac mortality compared to non-obese patients.
No takes yet. Share an insight, caveat, or question.
Obesity associated with fewer VTs but similar shocks and trends toward lower mortality in ICD patients; leaves open BMI effects on arrhythmic risk and survival.
Polat et al. (2022) studied this question.
