Why the study?
Many CAD patients develop recurrent angina pectoris after successful PCI despite having no need for secondary revascularization on repeat angiography, but predictors remain unclear.
What are the predictors of recurrent angina pectoris in patients who have undergone successful PCI but have no need for secondary revascularization?

May inform post-PCI risk stratification and counseling; leaves open causal effects and intervention benefits in prospective trials.
What are the predictors of recurrent angina pectoris in patients who have undergone successful PCI but have no need for secondary revascularization?
Patient characteristics such as female sex, older age, diabetes, elevated BMI, smoking, and LDL-C ≥1.8 mmol/L are associated with recurrent angina and coronary microvascular dysfunction after successful PCI.
