The aim of this study was to investigate the association between severe OSA and multivessel CAD.
We examined the apnea hypopnea index (AHI) using polygraphy (PG) in 60 consecutive patients with ACS who underwent coronary angiography. OSA was defined by AHI≥5 events per hour and was considered severe if the AHI≥30 events per hour. The Friesinger score was calculated for each patient from the coronary angiography to evaluate the severity of CAD.
The average age of patients was 59.73 years±10.1 years. The sex ratio was 1, 5.
61, 7% of patients had an AHI≥5 and 21,7% had severe OSA with AHI≥30. The Friesinger score was significantly greater in the group with multivessel CAD (11, 28±4, 17 versus 5, 35±3, 96, p=0,0001). There were no differences between patients having multivessel CAD and those with single-vessel CAD regarding clinical characteristics.
Table summarizes these results.
