The impact of perceived stress on the prognosis in patients undergoing percutaneous coronary intervention.

Objective: To assess the impact of perceived stress levels in patients undergoing percutaneous coronary intervention (PCI) on the occurrence of major adverse cardiovascular events (MACEs) within a 6-month follow-up period postprocedure.

Methods: A cohort of 339 hospitalized patients with coronary heart disease undergoing initial PCI was prospectively enrolled in the Department of Cardiology at two branches of Zhongda Hospital Affiliated to Southeast University between January 2022 and July 2022. Baseline data including demographic and clinical characteristics, along with the Chinese Perceived Stress Scale (CPSS), were collected. The occurrence of MACE was evaluated at 3 and 6 months post-PCI. Kaplan-Meier survival analysis and Cox regression models were engaged to analyze the relationship between perceived stress and MACE within 6 months after PCI.

Results: MACE occurred in 16.22% (55/339) of patients during the 6 following months. High CPSS at baseline was significantly associated with an increasing risk of short-term MACE occurrence (HR: 6.48, 95% confidence interval: 2.98-14.11, P < 0.05).

Conclusion: High perceived stress during the baseline period after PCI was significantly correlated with increased incidence of MACE within 6 months postprocedure. The perceived stress level could help to identify patients undergoing PCI at heightened risk of short-term MACE.
