E xercise and activity intolerance are the most frequent and debilitating symptoms in patients with mild and moderate congestive heart failure (CHF). Paradoxically, the severity of these symptoms correlates poorly with indexes of cardiac function such as the ejection fraction and hemodynamic measurements.1,2 This discordance has focused attention on pathophysiological changes in the periphery t...

OBJECTIVE To determine whether the acute adverse haemodynamic effects of beta blockade in patients with congestive heart failure persist during chronic treatment. DESIGN Sequential haemodynamic evaluation of heart failure patients at baseline and after three months of continuous treatment with the beta 1 selective antagonist metoprolol. SETTING Cardiac care unit in university hospital. PA...

Heart rate asymmetry (HRA) is considered as a physiological phenomenon seen in heart rates of healthy subjects. In this article, we propose a novel heart rate asymmetry index and assess the discriminative power of proposed index in comparison with conventional heart rate asymmetry indices. As an illustrative example we discriminate patients suffering from congestive heart failure (CHF) from a h...

1024x768 normal 0 false false false en-us x-none fa background : heart failure is a common health problem with poor prognosis. the gold standard for diagnosis is echocardiography but it is not always reachable, especially in emergency conditions. nt-pro-brain natriuretic peptide (nt-probnp) is a novel indicator for the diagnosis of heart failure and is being used in routine tests in emergency r...

congestive heart failure (chf) remains to be one of the major cardiovascular disorders in the world. due to the prevalence of chf related issues, it is prudent to seek out new prognostic predictors that would facilitate the prevention, monitoring, and treatment of the disease on a daily basis. a detection approach using entropy measures extracted from surface electrocardiograms (ecgs) and class...

conclusions this study will be an important step in creating an evidence base for the relative benefits of different educational strategies for reducing readmissions. results patients correctly answered three out of four, or 75%, of self-care teach-back questions. in the intervention group, greater time spent teaching was significantly associated with correctly answered questions (p < .001). th...
