Predictive value of pressure ulcer risk for obstructive coronary artery disease

Abstract Aim To investigate the relationship between pressure ulcers risk and severity of obstructive coronary artery disease (CAD) by invasive coronary angiography. Design Cross‐sectional study. Methods A total of 193 consecutive patients with underlying pressure ulcers risk who underwent invasive coronary angiography were enrolled. Subjects were divided into three groups according to severity of coronary artery stenosis. Pressure ulcers risk score, fall risk score, self‐care ability score and cardiovascular risk factors were compared among the three groups. Multivariate regression analysis and receiver operating curve analysis were performed to explore the diagnostic value of Braden score for left main or three‐vessel disease. Results 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.
