RESUMEN

Patients who undergo percutaneous coronary intervention (PCI) procedure frequently suffer post-PCI chest pain (PPCP). This study aims to identify the changes in PPCP level and investigate the predictors of PPCP among patients with coronary heart disease at three measurement times: on admission (T1), 24 hours post-PCI (T2), and 30 days post-PCI (T3). A repeated-measure design was used. Significant differences were observed in PPCP levels between T1 and T2; between T2 and T3; and between T1 and T3. The predictors of PPCP are (1) high-intensity physical activities duration per week, (2) cardiac enzyme level upon admission, (3) increased ejection fraction, and (4) increased heart rate. The results highlight that identifying predictors of PPCP helps in determining high-risk patients, whereby evidence-based interventions can decrease readmission rates and reduce patient exposure to unnecessary investigations and procedures. More research is needed to explain the changes in PPCP level and to confirm these results.
