434-P: Type 2 Diabetes Rather than the Presence of Significant Coronary Stenoses Is Associated with Quality of Life in Angiographied Coronary Patients

Chronic medical conditions such as type 2 diabetes (T2DM) or coronary artery disease (CAD) and their treatment have a crucial impact on patients’ daily life. The EQ-5D-5L questionnaire is a validated and widely used tool to measure the health-related quality of life (HRQL). We investigated and compared the HRQL in patients with or without T2DM and CAD. We included 481 consecutive patients undergoing coronary angiography for the evaluation of established or suspected stable CAD in a tertiary care setting in Central Europe. Patients’ HRQL was measured using the EQ-5D-5L, comprising the EQ index calculated from the domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. A response rate of 88.1% was achieved. From our patients, 166 (34.5%) had T2DM according to ADA criteria, and 254 (52.8%) had significant CAD with stenoses ≥50% at angiography. Patients with T2DM showed significantly lower EQ index values than patients without T2DM (0.891 [IQR=0.783-0.970]) vs. 0.943, [IQR=0.861-1.0], p=0.002)). Regarding the different dimensions of the questionnaire, patients with T2DM reported to have significantly more problems with anxiety and depression (p=0.002) and mobility (p
