Paradigm Shifts in the Treatment of Stable Ischemic Heart Disease
Key result
This editorial reviews paradigm shifts in treating stable ischemic heart disease, highlighting that the optimal threshold of ischemia for revascularization versus medical therapy remains undefined.
Why the study?
Does percutaneous coronary intervention added to optimal medical therapy improve long-term survival in patients with stable ischemic heart disease?
Population

This editorial emphasizes that the threshold of ischemia severity at which revascularization provides a survival benefit over medical therapy alone in stable ischemic heart disease remains undefined.
Limitations
- Selection bias due to missing quantitative coronary angiography and SPECT data in the analyzed cohort
- Missing extended follow-up data for a large portion of the original study population
- Imprecise methods for assessing ischemia and coronary artery disease burden
- Lack of information regarding subsequent revascularization after the original study period
- Limited generalizability to patients with severe CAD or severe left ventricular systolic dysfunction
- Selection bias due to only 60% of original patients meeting inclusion criteria
- Lack of precision in methods assessing ischemia and CAD burden
- Lack of information about subsequent revascularization (crossover)
- Exclusion of patients with severe CAD and severe left ventricular systolic dysfunction
