Predictive value of pressure ulcer risk for obstructive coronary artery disease.

Patients with more severe CAD had higher pressure ulcers risk. The percentage of high-pressure ulcers risk was highest in left main or three-vessel disease group, compared with control group and single- or two-vessel disease group. After adjusting for age, body mass index, diabetes, chronic kidney disease and other confounding factors, Braden score was an independent predictor of left main or three-vessel disease. Moreover, higher Braden score had a moderate area under the curve for excluding more severe CAD. In conclusion, among patients planning for coronary angiography, pressure ulcers risk assessment is conducive to predict the severity of obstructive CAD.
