Vascular Ehlers-Danlos syndrome patients had a 64% lower ventricular tachycardia risk than Marfan's syndrome patients (0.9% vs. 2.6%, RR 0.357, p=0.003).
Does the risk of ventricular tachycardia differ between patients with Vascular Ehlers-Danlos syndrome and Marfan's syndrome?
Patients with Vascular Ehlers-Danlos syndrome have a significantly lower risk of ventricular tachycardia and higher overall survival compared to propensity-matched patients with Marfan's syndrome.

Abstract Background Vascular Ehlers-Danlos syndrome (VEDS) and Marfan’s syndrome are associated with cardiovascular complications, including arrhythmias. However, ventricular tachycardia (VT) risk in these populations has not been frequently reported. Purpose This study aims to assess the VT risk in VEDS and Marfan's syndrome patients through an international database. Methods The TriNetX database was used to pull patients with a diagnosis of VEDS and Marfan's Syndrome. Baseline characteristics (e.g., demographics, cardiovascular comorbidities, etc.) were collected, and propensity score matching was performed to balance the cohorts. Risk analysis and Kaplan-Meier survival were used to assess outcomes. Results A total of 1,114 and 23,172 patients had VEDS and Marfan’s syndrome, respectively. After propensity score matching, each cohort included 1,091 balanced patients regarding demographics and clinical characteristics. The cohorts were balanced with a mean age of 37.7 ± 16.0 years in both groups. 68.7% and 68.8% were females in the VEDS and Marfan cohorts, the majority being White (82.2% in VEDS, 82.9% in Marfan’s). VT Incidence was lower in VEDS (0.9%) compared to Marfan’s syndrome (2.6%), with a risk difference of -0.016 (p = 0.003). Kaplan-Meier survival showed higher survival in VEDS (99.44%) vs. Marfan’s (94.04%, log-rank p = 0.002). The risk ratio for VT in VEDS was 0.357 (95% CI: 0.174, 0.732). Conclusion VEDS patients have a significantly lower VT risk compared to those with Marfan’s syndrome. These findings suggest significant differences in the arrhythmic burden between these connective tissue disorders, which can direct future risk stratification and management strategies.
