Key result
Higher residual Gensini score linked to ~2% greater cardiac mortality risk in HF patients post-PCI.
Why the study?
Coronary scoring systems for residual stenosis after revascularization are poorly understood in heart failure patients.
Is residual Gensini score associated with long-term cardiac mortality in patients with heart failure after percutaneous coronary intervention?
Observational (n=199)
No
Is residual Gensini score associated with long-term cardiac mortality in patients with heart failure after percutaneous coronary intervention?
Effect estimate: HR 1.022 (95% CI 1.011-1.035)
p-value: p=<0.001
The study aims to clarify the prognostic impact of residual stenosis using the Gensini score on long-term cardiac mortality in heart failure patients after PCI.
May refine post-PCI risk stratification in HF; hypothesis-generating and requires prospective validation before practice change.
Background:Coronary revascularization is important in heart failure (HF) with ischemic etiology. Coronary scoring systems are useful to evaluate coronary artery disease, but said systems for residual stenosis after revascularization are still poorly understood. Therefore, the aim of the current study was to clarify the prognostic impact of residual stenosis using a coronary scoring system, Gensini score, in HF patients after percutaneous coronary intervention (PCI).

Yokokawa et al. (2020) conducted an observational in Ischemic heart failure after percutaneous coronary intervention (n=199). High residual Gensini score (≥10) vs. Low residual Gensini score (<10) was evaluated on Cardiac death (HR 1.022, 95% CI 1.011-1.035, p=<0.001). In patients with heart failure after percutaneous coronary intervention, a higher residual Gensini score was significantly associated with increased long-term cardiac mortality (HR 1.022).
