In hospital outcome of percutaneous coronary intervention in patients with symptomatic obstructive coronary artery disease: limited Mansoura University experience in 2021.

Background: Coronary artery disease (CAD) is the leading cause of cardiovascular mortality worldwide. Percutaneous coronary intervention (PCI) is an established revascularization strategy for chronic coronary syndrome (CCS), with outcomes influenced by patient and procedural factors. However, real-world data on in-hospital PCI outcomes from developing countries remain limited. Aim: To evaluate in-hospital outcomes of PCI in patients with CCS and assess the relationship between baseline clinical risk factors and in-hospital major adverse cardiovascular events (MACE). Patients and Methods: This prospective observational cohort study included 150 patients with CCS (mean age 58.9±8.5 years; 106 males and 44 females) who underwent coronary angiography and PCI. Results: Only three patients experienced in-hospital MACE. We found no significant associations between MACE and demographic characteristics, cardiovascular risk factors, ECG or echocardiographic findings, laboratory parameters, previous revascularization, or target vessel. The only statistically significant univariate association with in-hospital MACE was observed for the number of implanted stents. Overall, the cohort demonstrated a low-risk clinical and anatomical profile. Conclusion: PCI in patients with chronic coronary syndrome was associated with a high procedural success rate, low incidence of in-hospital MACE, and favorable short-term outcomes. We could not establish reliable associations with in-hospital MACE because of the very low number of events; however, the number of implanted stents showed a statistically significant univariate association with MACE.
