Cardiac risk stratification in elective non-cardiac surgery: Role of NT-proBNP
AIM: The aim of the study was to investigate the utility of NT-proBNP measurement for the stratification of presurgical cardiac risk. METHODS: Cardiac risk before elective non-cardiac surgery was evaluated in 82 consecutive patients. From each patient a venous blood sample was drawn to determinate NT-proBNP levels. Patients were followed up over three months in order to detect the occurrence of cardiac adverse events. RESULTS: NT-proBNP was positively correlated (P<0.0001) with age, days of hospitalization (P=0.001) and ASA class (P=0.001). High surgical risk (P<0.0001), diabetes (P=0.004), dyslipidemia (P=0.006) and elevated levels of NT-proBNP (P<0.0001) were significantly correlated with…
Insulin resistance and diabetes increase fibrosis in the liver of patients with genotype 1 HCV infection.
OBJECTIVES: Metabolic factors may affect the course of chronic hepatitis C (CHC). Insulin resistance (IR) determines steatosis, but its direct role in affecting progression of hepatic fibrosis is less clear. We aimed to assess whether increasing degrees of IR, up to overt diabetes, are linked to steatosis and higher stages of fibrosis in patients with CHC resulting from genotype 1 HCV (G1-HCV). METHODS: Two hundred one consecutive patients with G1-HCV infection were evaluated by liver biopsy and anthropometric and metabolic measurements, including IR, by the homeostasis model assessment (HOMA). Nondiabetic patients were defined as insulin resistant if HOMA-IR was >2.7. All biopsies were …
