Sleep apnea prevalence in chronic heart failure patients with severe left ventricle systolic dysfunction
Original language description
Background. While sleep apnea (SA) might be a modifiable cardiovascular risk factor, recent data suggest that SA is severely underdiagnosed in chronic heart failure (CHF) patients especially with severe left ventricle systolic dysfunction. We therefore investigated the prevalence of SA in these patients. Methods. We prospectively studied 192 CHF patients with severe left ventricle dysfunction. All subjects were in stable condition and underwent sleep evaluations using Embletta Gold during hospitalization. Using the apnea-hypopnea index (AHI), groups were defined as patients without SA (<5 events/h), mild SA (5-15 events/h), moderate SA (15-30 events/h), and severe SA (GREATER-THAN OR EQUAL TO30 events/h). Results. Using a threshold of AHIGREATER-THAN OR EQUAL TO5 events/h, SA was present in 75% of patients with CHF and severe systolic dysfunction. Moderate to severe SA was present in 48.4% of them. Conclusion. There is a high prevalence of SA in patients with CHF with severe systolic dysfunction. Whether diagnosis and treatment of SA will significantly improve outcomes in these patients remains to be determined.
