Abstract

Purpose. To study the effect of polyvascular disease (PolyVD) on quality of life (QoL) of coronary artery disease (CAD) patients. Materials and methods. We examined 807 CAD patients (59,0 ± 8,0 years old; 648 men and 159 women), who were examined before planned coronary artery bypass surgery (CABG). The patients were additionally examined for subclinical stenosis of non-coronary arteries to identify the signs of PolyVD (artery stenosis 30% and more were included). The following groups were formed: PolyVD group (n = 336) and non-PolyVD group (n = 473). The groups were compared in terms of quality of life and depression. QoL was analyzed with the help of SF36 questionnaire, depression level – with the help of “Depression scale” questionnaire. Results. In PolyVD group integral indicators of QoL were lower compared to non-PolyVD group both as for physical component (69 (51,5;72,3) and 71,3 (61,3;75,8) points; р = 0,004), and for psychological component (62.8 (48.5, 72.0) and 63.5 (57.0, 72.8) points, p = 0.045) of QoL. In multiple regression analysis the independent effect on physical component of QoL was provided by PolyVD (OR = 0,679; 95%CI 0,477–0,966; р = 0,031) and functional class of CHF (OR = 0,514; 95%CI 0,378–0,698; р < 0,001), on psychological component – functional class of CHF (OR = 0,577; 95%CI 0,425–0,784; р<0,001). Conclusion. CAD patients with PolyVD as compared to patients with discrete lesion of coronary arteries have a higher level of depression and reduce of quality of life both as for certain scales of SF-36 questionnaire and integral indicators of physical and psychological components of QoL. In multivariate analysis the independent factors associated with a reduction in overall physical health were PolyVD presence and CHF severity, associated with a reduction in overall psychological health – only CHF severity.
