Taiwan Society of Cardiology Heart Failure Registry 2020: Rationale and Design.

Background: Heart failure (HF) is a significant public health problem worldwide. Death and rehospitalization rates are similar across different HF phenotypes. However, the existing Taiwanese HF registries mainly enrolled inpatients with HF and reduced ejection fraction (HFrEF) before 2019, so their results may not apply to outpatients or patients with HF with mildly reduced ejection fraction (HFmrEF) and HF with preserved ejection fraction (HFpEF) phenotypes.

Methods: The Taiwan Society of Cardiology Heart Failure Registry 2020 is a prospective, multicenter, observational registry that will enroll patients with HF from 27 hospitals in Taiwan between 2020 and 2022 and will be followed for two years. Patients eligible for enrollment include those admitted due to acute decompensated heart failure or outpatients with a history of hospitalization for heart failure within the past six months. The registry will collect patient demographics, medical history, HF diagnosis, medication use, examination results, and comorbidities. The registry plans to enroll 3,370 patients, with the distribution of HFrEF/HFmrEF/HFpEF as 59%/13%/28%. Follow-up intervals will occur every six months for up to two years to monitor clinical outcomes and major cardiac interventions. The registry will conclude in December 2024.

Conclusions: The Taiwan Society of Cardiology Heart Failure Registry 2020 is a comprehensive and meticulous effort to demonstrate the epidemiology, adherence to guidelines, clinical outcomes, and disease progression of Taiwanese patients with HF in contemporary clinical practice.
