Article Synopsis
- The study investigates the link between atherosclerosis (plaque buildup in arteries) and types of myocardial ischemia (insufficient blood flow to the heart) in patients without significant coronary artery blockage (INOCA).
- It employs advanced invasive tests to assess coronary microvascular function and quantifies plaque burden using the Gensini score, which takes into account the severity of artery blockage.
- Findings reveal that higher Gensini scores correlate with poorer microvascular function, and different INOCA endotypes (like microvascular angina and vasospastic angina) show variations in plaque scores, indicating the complexity of heart conditions in patients without obvious artery blockage.
Assessing coronary physiology after stent implantation facilitates the optimisation of percutaneous coronary intervention (PCI). Coronary artery disease (CAD) patterns can be characterised by the pullback pressure gradient (PPG) index. The impact of focal vs.

Understanding patient and procedural factors associated with post-PCI angina may inform alternative approaches to treatment.
Methods: Two hundred thirty patients undergoing PCI completed the Seattle Angina Questionnaire (SAQ-7) and European quality of life-5 dimension-5 level (EQ-5D-5L) questionnaires at baseline and 3 months post-PCI.
