Observing Adults with Arrhythmia-Induced Cardiomyopathy to Understand Diagnosis and Outcomes

What this Trial Is About

Researchers are studying arrhythmia-induced cardiomyopathy AiCM, a heart condition linked to irregular heart rhythms that may cause reduced heart function. This observational study aims to better understand how common AiCM is, improve early diagnosis, and evaluate the current treatments and outcomes for patients suspected of having AiCM. The study includes a retrospective review of past patient data and a prospective follow-up of patients over time. The study involves two parts a retrospective cohort examining 1200 patients who had reduced heart function and arrhythmias between 2010 and 2021, and a prospective cohort enrolling 1500 patients with suspected AiCM. Diagnosis is confirmed by two cardiologists reviewing clinical data, heart tests, and other assessments. Data collected includes medical history, hospitalizations, heart tests, and patient questionnaires on major heart events and quality of life, with follow-ups up to five years. Participants will provide data through medical record review and questionnaires assessing major cardiovascular events and quality of life at multiple timepoints, including 6 months, 1 year, 2 years, and 5 years. The study tracks incidence of AiCM, adverse heart events, rehospitalizations, and quality of life changes. Monitoring includes ECGs, lab tests, echocardiography, and other cardiac diagnostics. This long-term observation aims to improve understanding of AiCM and its management.
