This systematic review and cumulative meta-analysis evaluated survival trends in Duchenne muscular dystrophy (DMD) across eras, analyzing over 13,000 patients. The study found that median survival for patients receiving home mechanical ventilation (HMV) was 29 years, compared to 19 years for non-ventilated patients. Survival has improved significantly over time, particularly with advancements in multidisciplinary care.
Key findings
- Median survival for ventilated patients was 29 years, compared to 19 years for non-ventilated patients.
- Survival improved progressively over time in both ventilated and non-ventilated groups.
- Heart failure medications were associated with longer survival (p=0.002 for renin-angiotensin inhibitors, p=0.02 for β-blockers).
- The cause of death has shifted from respiratory to cardiac issues.
Why it matters
Understanding survival trends in DMD is crucial for clinicians to provide appropriate care and interventions. The shift in mortality causes emphasizes the need for ongoing cardiac management and multidisciplinary approaches to improve patient outcomes.
