2 STICH trial: conclusions The STICH trial definitively shows that adding SVR to CABG provides no clinical benefit be yond that of CABG alone in the study population.
3 STICH trial: conclusions The STICH trial definitively shows that adding SVR to CABG provides no clinical benefit be yond that of CABG alone in the study population. Both operative str rategies provided d similar short- and long-term relief of angina and HF and improvement in 6-minute walk te est performance.
4 Criticisms The eligibility criteria were changed during the study and in 2003 the heart failure symptoms were abolished.
5 Criticisms The eligibility criteria were changed during the study and in 2003 the heart failure symptoms were abolished. The LV volume was not anymore an eligibility criterion. Only the EF 35% was kept. The study then switched from heart fail lure patients to ischemicc patients.
