Evaluation of postoperative myocardial injury by heart-type fatty acid-binding protein in off-pump coronary artery bypass grafting surgery.

Background And Goal Of Study: Postoperative myocardial infarction is a serious and frequent complication of cardiac surgery. Nonetheless, diagnosis in this context it is occasionally challenging. We sought to evaluate the kinetics and diagnostic accuracy of the new biomarker « heart-type fatty acid-binding protein » (h-FABP) in the early detection of myocardial injury in patients undergoing off-pump coronary artery bypass grafting, compared with classical biomarkers.

[Hyperlactatemia in surgical ablation of atrial fibrillation and cardiac surgery. Is it a predictive factor of postoperative morbidity?].

Introduction: Increased serum lactate in postoperative cardiac surgery is very common and its pathogenesis is due to multiple factors. The elevation of serum lactate is associated with tissue hypoxia (hyperlactatemia type A) and non-hypoxic (hyperlactatemia type B) metabolic disorders. The aim of the study was to assess the evolution of postoperative lactate in surgical atrial fibrillation ablation during cardiac surgery, and to determine whether lactate levels could be predictors of morbimortality.

[Sepsis, cardiomyopathy and human immunodeficiency virus infection: presentation of a case].

Sepsis in patients with human immunodeficiency virus (HIV) may be associated with the appearance of cardiac dysfunction. This is a challenge, both when making the differential diagnosis and determining the proper treatment, as there are numerous risk factors: Myocarditis due to the HIV itself, the presence or absence of highly active antiretroviral therapy, toxic substances, and cardiomyopathy associated with sepsis. The diagnostic and therapeutic approach to an HIV positive patient with septic shock and cardiac dysfunction is described, as well as a brief review of the different causes of cardiomyopathy which may affect this group of patients is also presented.
