Fig 2 End-systolic volume index (ESVI) reduction expressed as median percentage change with 25th and 75th interquartile range (in brackets) for the SSVR (white bars) and NSSVR (black bars) groups at follow-up. The ESVI reductions were significantly greater in the NSSVR group at both 4-month and 4-year follow-up.

Fig 3 End-diastolic volume index (EDVI) reduction expressed as median percentage with the 25th and 75th interquartile range (in brackets) for SSVR (white bars) and NSSVR (black bars) groups at follow-up. The EDVI reductions were greater in the NSSVR group at both 4-month and 4-year follow-up.

Fig 4 Canadian Cardiovascular Society (CCS) angina class and New York Heart Association (NYHA) heart failure symptoms at baseline and follow-up. (A) The non-STICH surgical ventricular restoration (NSSVR) group had a larger proportion of patients with CCS class III-IV at baseline. The proportion of patients with no angina increased at 4-month and 4-year follow-up for both groups. (B) There were more patients in the NSSVR group with advanced class III-IV heart failure symptoms at baseline and the symptom class improved for both groups at both 4-month and 4-year follow-up.
