MORIEL, Gisele et al. Quality of life in patients with severe and stable coronary atherosclerotic disease. Arq. Bras. Cardiol. [online]. 2010, vol.95, n.6, pp.691-697.  Epub Nov 19, 2010. ISSN 0066-782X.

BACKGROUND: There are few data on the factors decreasing quality of life (QoL) in patients with coronary artery disease (CAD) before a percutaneous coronary intervention (PCI). OBJECTIVE: To associate clinical variables with QoL scores in patients with stable CAD before the PCI and with unfavorable outcomes, 12 months after the procedure. METHODS: The present is a longitudinal study of 78 patients (43 men and 35 women), before an elective PCI. The associations between the QoL scores (SF-36 questionnaire) and age, sex, weight, body mass index, diabetes mellitus (DM), arterial hypertension, dyslipidemia, current smoking, previous cardiovascular event or PCI, glycemia control and blood pressure (BP) were analyzed by multivariate logistic regression. We also analyzed the associations between the clinical features and the unfavorable outcomes (death due to any cause, heart failure or nonfatal infarction). The level of significance was set at p < 0.05. RESULTS: The medians of the QoL scores were < 70 percentage in all domains. Female sex, age < 60 years, previous cardiovascular event or PCI, BMI > 25 kg/m², DM and high BP were associated with a higher degree of impairment of at least one QoL score. Female sex (OR: 7.19; 95%CI: 1.55 - 33.36; p = 0.012), previous cardiovascular event (OR: 3.97; 95%CI: 1.01 - 15.66; p = 0.049) and PCI failure (OR: 10.60; 95%CI: 1.83 - 61.46; p = 0.008) were associated with increased risk of combined outcome. CONCLUSION: In the presence of CAD, women and patients with comorbidities present a higher degree of QoL impairment. The unfavorable outcomes 12 months after the PCI are associated with the female sex, previous event or procedure failure.
