Impact of COVID-19 on Heart Failure Hospitalization and Outcome in India – A Cardiological Society of India Study (CSI-HF in COVID 19 Times Study – “The COVID C-HF Studyâ€)

Part 1. Individual patient based acute HF retrospective registry 2020 Vs 2019:

In this multicentric, retrospective, cross-sectional registry, we retrospectively include consecutive patients presenting with acute HF at various participating hospitals across the country during a 6-months period in 2020 (1st of July to 31st December 2020). All cases of acute HF admitted during the corresponding period in the year 2019 will serve as historical controls. Patients with a first acute myocardial infarction in the 2 weeks preceding clinical presentation will be excluded. Patients with alternative diagnoses clearly causative of symptoms will also be excluded. The 2016 European Society of Cardiology (ESC) criteria (12) will be used to define cases of heart failure.

The parameters to be studied include type of HF, new-onset or worsening of pre-existing heart failure, clinical characteristics on index admission, risk factors, etiology for heart failure, history previous myocardial infarction, history of previous hospital admissions, treatment received during hospital admission, diagnostic coronary angiography, percutaneous coronary interventions, and coronary artery bypass graft surgery rates.

Part 2. Hospital statistics on HF-related procedures

We wish to find the differences in the number of various advanced HF procedures. In a predesigned proforma we will collect the total numbers of ICD, CRT, mechanical assist devices including IABP for HF, percutaneous devices, LVAD and heart transplantations performed in the study period in 2020 as compared to corresponding volumes in 2019.
