Introduction: Managing in-stent restenosis (ISR) remains a critical challenge in interventional cardiology. Drug-eluting balloons (DEB) have emerged as a promising treatment option for ISR in patients with drug-eluting stents (DES). A recent study investigates the incidence of symptom-driven coronary angiography (SDCA) post-DEB treatment and its implications.

Key Findings from the Study:
- The study evaluated 28 patients who underwent DEB treatment for DES-ISR.
- SDCA occurred in 54% of patients within two years of follow-up.
- Within the first year, 11% required SDCA with target lesion revascularization (TLR), while 36% had SDCA without TLR.
- 30% of patients undergoing SDCA without TLR had acute coronary syndrome (ACS) but did not require percutaneous coronary intervention (PCI).
Clinical Implications and Considerations:
- High Cardiovascular Risk Group: The findings highlight that patients requiring SDCA may represent a subgroup with higher cardiovascular risk.
- Importance of Non-Invasive Imaging: Alternative imaging modalities could help reduce unnecessary angiographic procedures.
- Need for Larger Studies: The study suggests that more extensive research is necessary to validate SDCA as a meaningful clinical marker.
Integration of External Medical Sources: The American Heart Association (AHA) underscores the importance of precise risk stratification and timely intervention in coronary artery disease management to optimize patient outcomes.
