[Single cardiac troponin T measurement predicts risk for adverse outcome in decompensated heart failure].

Background: The slight increase in cardiac troponin in the blood of patients with heart failure (HF) suggests that myofibrils are degraded in the myocardium and released in the circulation, reflecting a continuous and progressive injury process in the contractile system.

Objective: To correlate the serum levels of cardiac troponin T (TnT) at the hospital admission of patients with decompensated HF and prognosis.

Methods: A total of 79 consecutive patients, hospitalized due to decompensated HF, with LVEF < 45%, were included in the study.

Microalbuminuria in nondiabetic and nonhypertensive systolic heart failure patients.

The American Diabetes Association and the National Kidney Foundation define microalbuminuria as an albumin (microg)/creatinine (mg) ratio (ACR) between 30 and 300 microg/mg regardless of sex. Microalbuminuria is associated with increased cardiovascular risk. The authors evaluated the prevalence of microalbuminuria in nondiabetic and nonhypertensive systolic heart failure (SHF) patients.
