Central Sleep Apnoea Is Related to the Severity and Short-Term Prognosis of Acute Coronary Syndrome.

ABSTRACT:

Objective

To evaluate the relation of central sleep apnoea (CSA) to the severity and short-term prognosis of patients who experience acute coronary syndrome (ACS).

Methods

Observational study with cross-sectional and longitudinal analyses. Patients acutely admitted to participating hospitals because of ACS underwent respiratory polygraphy during the first 24 to 72 h. CSA was defined as an apnoea-hypopnoea index (AHI) >15 events•h-1 (>50% of central apnoeas). ACS severity (Killip class, ejection fraction, number of diseased vessels and peak plasma troponin) was evaluated at baseline, and short-term prognosis (length of hospitalization, complications and mortality) was evaluated at discharge.

Results

A total of 68 CSA patients (AHI 31±18 events•h-1, 64±12 years, 87% mal
