endothelial nitric oxide synthase (enos) produces nitric oxide (no) from l-arginine and is important for the maintenance of cardiovascular homeostasis. congestive heart failure (chf) generally results in increased pulmonary blood flow and if untreated leads to pulmonary hypertension and end stage heart failure. we therefore hypothesized that increased pulmonary flow without changes in pressure ...
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...
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...
Introduction: Congestive Heart Failure (CHF) is a pathophysiologic state in which an abnormality of cardiac function is responsible for the failure of the heart to pump blood at a commensurate rate with the requirements of the metabolizing tissues and/or allows it to do so only from an abnormally elevated diastolic volume. In this study, the prevalence of precipitating factors of CHF in Semna...
Abstract Background: Opinions differ about the role of smoking cigarettes on homogeneity of ventricular repolarization. The aim of this study was to investigate the short term effect of cigarette smoking on QT dispersion (QTD) as a measure to evaluate the ventricular repolarization homogeneity in patients with Congestive Heart Failure (CHF) and healthy smokers. Materials and methods: In this ex...
Multiscale entropy (MSE) is a powerful method for determining the complexity of random time series. In this paper we, investigate the cardiac heart interbeat interval (RR) time series by introducing a new method based on MSE, called multicomponent complexity (MCC) and find clear difference between healthy samples and samples with Congestive heart failure (CHF) disease.
Level crossing is a powerful method for analyzing the random time series. In this paper by introducing this method we investigate the beta noises and represent differences between 1/f noise and white noise and also research the cardiac heart interbeat interval (RR) time series and find clear distinctions between healthy samples and samples with Congestive heart failure (CHF) disease.
BACKGROUND It has been shown that heart rate variability is decreased in patients with congestive heart failure and that depressed heart rate variability is associated with a propensity to ventricular arrhythmias. Little is known, however, about heart rate variability in patients with both congestive heart failure and ventricular arrhythmias. METHODS Spectral heart rate variability was analys...
Introduction & Objective: Cardiovascular diseases are the main cause of death in all countries in the recent century and congestive heart failure (CHF) is the reason of death in most pa-tients . The most common causes of CHF are ischemic heart disease, myopathies , valvular disease and hypertension. Mortality reduction is the aim in CHF treatment. Combination of glucose-insulin-potassium (GIK...
