Prognostic Impact of PMI in Stable CAD Undergoing PCI

The Prognostic Impact of Periprocedural Myocardial Injury in Stable Coronary Artery Disease Patients Undergoing Elective Percutaneous Coronary Intervention

This is a single-center, observational, prospective study. This study aims to observe the effect of periprocedural myocardial injury on cardiovascular events in patients undergoing elective percutaneous coronary intervention, and to detect the levels of serum inflammatory factors before and after intervention to predict the occurrence of periprocedural myocardial injury and its association with cardiovascular events.

Inclusion Criteria:

• underwent elective coronary stenting
• patients permit informed consents

Exclusion Criteria:

• acute STEMI
• NYHA class III-IV heart failure
• moderate-to-severe valvular disease
• missing post-PCI troponin results
• active infection, respiratory failure
• liver dysfunction (liver enzyme >3xURL or bilirubin >2xURL),
• malignancy and systemic connective tissue disease
• unable to get a informed consents
