We aimed to investigate the association between sex and surgical outcomes in patients with ischaemic HF undergoing surgical ventricular reconstruction and coronary artery bypass grafting. <strong>Methods and results: </strong>From July 2001 to June 2017, 648 patients [111 women (17%) and 537 men (83%)] were referred to our centre. Follow-up continued through June 2018. All patients underwent surgical ventricular reconstruction; coronary artery bypass grafting was performed in 582 patients (90%). Primary outcome was defined as all-cause mortality. Secondary outcome included all-cause mortality or all-cause hospitalization. Women were older (70 vs. 65 years, P &lt; 0.0001) with lower body surface area (1.70 vs. 1.86 m<sup>2</sup> , P &lt; 0.0001). Women had more diabetes (36% vs. 24%, P = 0.005) and a higher New York Heart Association classification (Class III/IV 65.7% vs. 47.8%, P = 0.0006), without any significant difference in medical therapy except for a higher use of oral antidiabetic agents in women (P = 0.029). At baseline, the left ventricular (LV) end-diastolic volume index was significantly lower in women [median 107.06 (80.6-127.81) vs. 113. 04 (94.33-135.52) mL/m<sup>2</sup> , P = 0.0078] but not the LV end-systolic volume index (ESVI) [median 73.45 (51.93-96.79) vs. 77.03 (60.33-95.71) mL/m<sup>2</sup> , P = 0.1393] and the ejection fraction (median 31% vs. 32%, P = 0.150). Women had a higher rate of anterior remodelling (90.9% vs. 79.1%, P = 0.0129), without evidence of differences in mitral valve insufficiency (P = 0.761 for Grade 0 to 4) and mitral surgery (P = 0.810). After surgery, the percentage of reduction in LV ESVI was higher in women than in men (median ΔLV ESVI -42.06 vs. -31.99, P = 0.0003). Mortality within 30 days occurred in 43 patients (6.64%): 12 women (10.81%) and 31 men (5.77%, P = 0.0522). Over a median follow-up of 9.8 years, all-cause mortality occurred in 269 patients (41.64%), without significant difference between women (45.9%) and men (40.7%). There was no evidence of difference of all-cause death between sexes (log-rank = 0.2441). When considering mortality and first hospitalization as competing events, Gray's test showed no difference of cumulative incidence functions (all-cause hospitalization, all-cause death, and combined endpoint) according to sex (P = 0.909, P = 0.445, and P = 0.429, respectively). <strong>Conclusions: </strong>In this study, long-term outcomes for women and men with ischaemic HF undergoing complex cardiac surgery were equivalent. Albeit older and more symptomatic, women should not be denied this type of cardiac surgery.
