Recent key RWD publications in HF, ACS, and AF

Data source	Participants	Findings	Reference
Gulf CARE	5,005 patients hospitalized with acute HF	ACS was the most common precipitating factor for new-onset HF (39.2%) and non-compliance with medications the most common precipitating factor for decompensated chronic HF (27.8%)	[30]
