The MUSIC Database: Sudden Cardiac Death in Heart Failure Patients

The MUSIC study is a prospective, multicenter study designed with the aim of developing prognostic models for sudden cardiac and total mortality in mild-to-moderate chronic heart failure (CHF).The database, now made available at Physionet, includes a total of 992 consecutive patients with symptomatic CHF corresponding to New York Heart Association (NYHA) classes II and III.All patients had a 24-hour, 3-lead Holter ECG recorded at enrollment, plus available demographic and relevant clinical data.Primary outcomes were cardiac death, either sudden cardiac death (SCD) or pump failure death (PFD) at the end of the 4-year follow-up.
