Supports graft patency assessment for post-CABG symptom counseling; leaves open multifactorial contributions in contemporary cohorts.
What are the mechanisms and rates of symptom relief after coronary bypass grafting?
Symptom relief after CABG is multifactorial, driven primarily by graft patency but also influenced by intra-operative MI, LV function changes, native vessel progression, and completeness of revascularization.
M. H. Frick (1976) conducted a review in Coronary artery disease / Angina. Coronary bypass grafting was evaluated on Subjective symptomatic improvement. Coronary bypass surgery provides subjective symptomatic improvement in 90% of patients (70% by objective exercise testing), with graft patency playing a dominant role in pain relief.
