Perceived stress in Chinese patients with coronary heart disease: a cross-sectional study

Abstract

ObjectiveStudies have shown that chronic stress is closely linked to the occurrence and development of cardiovascular disease. To date, few studies have focused on perceived stress in coronary heart diseases (CHD) patients and the possible factors influencing the stress. This study aims to investigate the perceived stress of patients with CHD and determine the individual attributes closely associated with it.DesignA cross-sectional study.ParticipatesA total of 2215 patients with CHD were enrolled and perceived stress was assessed with the Chinese version Perceived Stress Scale (CPSS). Participants were divided into two groups due to CPSS score and binary logistic regression was applied to analyse the factors that affected perceived stress level.ResultsThe mean CPSS score of Chinese patients with CHD was 27.16±6.35 Compared with participants who received senior middle school education or below, those with a university degree had a higher probability of high perceived stress (OR 1.453, 95% CI 1.206 to 1.750); this difference was more evident in participants with a master or doctoral degree (OR 1.928, 95% CI 1.290 to 2.882). Also engaging in mental labour (OR 1.389, 95% CI 1.144 to 1.686), having children (OR 2.226, 95% CI 1.098 to 4.515) and having a habit of risky alcohol consumption (OR 1.492, 95% CI 1.146 to 1.944) were associated with perceived stress.ConclusionPatients who had higher educational attainment, engaged in mental labour, had children, and had a habit of risky alcohol consumption were much easier to perceive the stress.
