The standard dietary regimen followed during cardiological rehabilitation after major cardiovascular surgery aids recovery from surgical insult, but fails to normalize high glucose levels. Vitamin B12 supplementation should be encouraged because of its substantial reduction during the rehabilitation period.

■ BACKGROUND: Inflammatory and vascular markers have proved to be predictors of outcome in myocardial infarction and heart failure. We evaluated several circulating markers of cardiac stress, inflammation, and endothelial function to investigate their ability to predict short-term functional recovery and long-term clinical outcome in heart surgery patients undergoing inpatient rehabilitation.■ METHODS: This prospective, multicenter study enrolled 223 patients after heart surgery, included in a 3-week program of standardized and supervised physical training. The association between biomarkers (pentraxin-3 [PTX3], brain natriuretic peptide, high-sensitivity cardiac troponin-T [hs-cTnT] and C-reactive protein [hsCRP], creatine kinase, myoglobin, and urinary albumin excretion [UACR]) and exercise capacity (6-minute walk test, 6MWT) or 1-year incidence of major adverse cardiovascular events (MACE) was tested in models that included biohumoral markers, and clinical and instrumental variables.■ RESULTS: The patients (69.5% men, mean age of 67 Ϯ 11 years) were enrolled after valvular surgery (52.7%) and 58.6% after coronary artery bypass grafting (CABG
