Systolic and Non-Systolic Heart Failure Equal Threats

The patients were Olmstead County residents with incident or prevalent heart failure (inpatients or outpatients) prospectively recruited from 2003 to 2005. Approximately 80% of the patients had diastolic dysfunction. However, patients with a reduced ejection fraction had more moderate or severe diastolic dysfunction than patients with preserved ejection fraction (odds ratio, 1.67; 95% confidence interval, 1.11-2.51; P=.01), the researchers reported.
