The Claim
Among patients with structural heart disease undergoing epicardial ventricular tachycardia ablation, higher body mass index is associated with a 2.92-fold increased risk of ventricular tachycardia recurrence during a median 17-month follow-up period.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Patients with structural heart disease who have a higher body mass index are more likely to experience a return of ventricular tachycardia after epicardial ablation, based on a median follow-up of 17 months.
See the scientific wording
Among patients with structural heart disease undergoing epicardial ventricular tachycardia ablation, higher body mass index (BMI) was associated with a 2.92-fold increased risk of ventricular tachycardia recurrence during a median 17-month follow-up, suggesting adiposity may influence arrhythmia substrate stability or ablation efficacy.
Excess fat around the heart releases chemicals that cause scar tissue to form in the heart muscle, making it harder for the ablation procedure to permanently stop abnormal heart rhythms.
What the research says
1 studyThis study found that people with higher body weight were more likely to have dangerous heart rhythms come back after heart surgery to fix them. So, being heavier might make the surgery less effective at stopping the bad heart rhythms.
