Prediction of Post Percutaneous Coronary Intervention Myocardial Ischaemia

Area of Science:

• Cardiology
• Interventional Cardiology

Background:

• Revascularization improves quality of life for most patients.
• A significant subset experiences persistent or recurrent myocardial ischemia post-procedure.

Purpose of the Study:

• To explore the determinants of persistent myocardial ischemia after revascularization.
• To identify strategies for predicting and preventing post-percutaneous coronary intervention (PCI) angina.

Main Methods:

• Review of technological advances in imaging and physiological evaluation of epicardial plaques.
• Analysis of recent clinical studies on post-PCI myocardial ischemia.
• Evaluation of patient selection and invasive assessment strategies.

Main Results:

• Inaccurate stenosis evaluation, incomplete revascularization, stent failure, and disease progression are common explanations for symptom recurrence.
• Abnormal coronary vasomotion and increased myocardial resistance are identified as frequent causes of post-PCI ischemia.
• Current imaging and physiological evaluations have not fully resolved the issue of recurrent ischemia.

Conclusions:

• Abnormal coronary vasomotion and increased myocardial resistance are critical factors in post-PCI myocardial ischemia.
• Enhanced patient selection, clinical prediction models, and invasive angiography are crucial for predicting and managing post-PCI angina.
