Neutrophil-to-lymphocyte ratio (NLR) has been associated with poor outcomes in patients with acute coronary syndromes. However, its role for risk stratification in acute decompensated heart failure (ADHF) has not been well described. In this study, 1,212 consecutive patients admitted with ADHF who had total white blood cell and differential counts ...

Previous studies have reported that patients with mitral valve prolapse (MVP) may display autonomic dysfunction. Measurement of heart rate variability (HRV) and P-wave dispersion (PWD) may provide insights into the functional state of the autonomic nervous system. Heart rate variability (HRV) has been used as a noninvasive marker of autonomic ...

Patients with systolic heart failure are thought to be at increased risk for thromboembolic events. Although these patients may have increased hypercoaguable markers, the incidence of stroke is thought to be relatively low. Still, oral anticoagulation with warfarin is sometimes prescribed in these patients to prevent potential thromboembolic events. Current ...
