Psychosocial stress and well-being in patients presenting with acute myocardial infarction in a tertiary care center

Background: Psychosocial factors such as stress have been previously implicated as a risk factor for cardiovascular diseases (CVDs). There is little evidence regarding the prevalence of stress among patients with acute myocardial infarction (AMI). Methods: A total of 903 patients with AMI enrolled in the North Indian ST-Segment Elevation Myocardial Infarction (NORIN-STEMI) registry were included in this study. Perceived stress in these subjects was evaluated using the Perceived Stress Scale-10 questionnaire while the World health Organization (WHO-5) Well-being Index was used to evaluate psychological well-being. All these patients were followed up for one month and major adverse cardiac events (MACE) were determined. Results: A majority of patients with AMI had either severe (478 [52.9%]) or moderate stress (347 [38.4%]) while low stress levels were observed in 78 [8.6%] patients. Additionally, most of the patients with AMI (478 [53%]) had WHO-5 well-being index <50%. Subjects with severe stress were younger (50.86 ± 13.31; P < 0.0001), more likely to be males (403 [84.30%]; P = 0.027), were less likely to have optimal level of physical activity (P < 0.0001) and had lower WHO-5 well-being score (45.54 ± 1.94%; P < 0.0001) as compared to those with low and moderate stress levels. On 30-days follow-up, subjects with moderate/severe stress had higher MACE however, the difference was non-significant (2.1% vs 1.04%; P = 0.42). Conclusion: A high prevalence of perceived stress and low well-being index was observed in patients presenting with AMI in India.
