Heart failure & cardiomyopathies
Long-term cardiovascular outcomes among immigrants and non-immigrants in cardiac resynchronization therapy: a nationwide study
Authors' conclusion
No overall differences in efficacy of CRT in improving outcomes between immigrants and non-immigrants were identified.
Study context
- Population
- Patients with heart failure (HF) undergoing first-time cardiac resynchronization therapy (CRT) implantation in Denmark, 2000–2017
