Background Out-of-hospital patients presenting with atypical chest pain and complete left bundle branch block(LBBB)have to be stratified for the presence of coronary artery disease and the risk of developing heart failure(HF).We investigated the pro-gnostic role of coronary CT-angiography(CTA)and echocardiographic global longitudinal strain(GLS)in those patients in a mid-term *** Out-of-hospital patients with LBBB underwent echocardiography and a 64-slice CT angiography were evaluated *** of HF or a cardiovascular death were the events *** Seventy-eight patients(32 female;mean age:66.0±10.4 years were *** a follow-up of 33 months(IQR:17-77),one patient(1.5%)experienced a cardiovascular death,14 patients(17.9%)required urgent outpatient visits due to acute de-compensated HF(12 hospitalizations).Echocardiography showed a slightly reduced left ventricular ejection fraction(LVEF)(50.0%±9.8%)and GLS within the normal range(-16.2%±4.1%).CTA analysis showed coronary stenosis>50%in 28 patients(35.9%).A high Agatston score(>100)was observed in 29.5%.Notably,25 patients(32.1%)were diagnosed with left main coron-ary artery disease and 15 patients(16.7%)underwent revascularization during the follow *** associations were ob-served between events and LVEF(P=0.001),diastolic dysfunction grade≥2(P=0.02),GLS(P<0.001),multiple coronary stenos-is(P=0.04)and Agatston score(P=0.05).Multivariate analysis confirmed the relationships with LVEF(R^(2)=0.89,P<0.001),dia-stolic dysfunction(R^(2)=3.30,P=0.04),GLS(R^(2)=1.43,P<0.001),and Agatston score(R^(2)=1.01,P=0.05).Conclusions In patients with complete LBBB,CTA and GLS identified those at a high risk of development HF.

The CAMINO trial by Görgec et al.(1)assessed the added diagnostic value of contrast-enhanced(CE)magnetic resonance imaging(MRI)using gadoxetic acid and diffusion-weighted imaging for patients with colorectal liver metastases(CRLMs)scheduled for curative treatment(surgical resection,thermal ablation,or both).The study explored how often liver(MRI)changes therapeutic strategy compared to using only a CE computed tomography(CT)*** MRI’s widespread use in staging for CRLMs,guidelines remain vague,leaving decisions to the surgeon’s preference and expertise.
