Influence of Pullback Pressure Gradient on Residual Angina at One Year

In patients with flow-limiting coronary artery disease, a focal disease pattern defined by high PPG was associated with greater symptomatic relief at 1 year compared with diffuse disease (low PPG). By capturing the underlying pathophysiologic distribution of epicardial disease and its relation to post-treatment symptom relief, PPG may support a more tailored revascularization decision-making and percutaneous coronary intervention strategy.
