Congestive heart failure (CHF) affects more than 2 million Americans and requires greater than 900,000 hospitalizations each year. The incidence of CHF is increasing because of the increasing age of the American population and the use of newer medications and technologies that have increased survival...
2.Pathophysiology of Congestive Heart Failure and Angina The pathophysiology ofcongestive heart failureis rooted in the heart's inability to pump sufficient blood, leading to a cascade of neurohormonal and hemodynamic changes. These changes include the activation of the renin-angiotensin-aldosterone syste...

The article reports on a study conducted by Florence Sens and colleagues which reveals that patients with congestive heart failure (CHF) who starts on peritoneal dialysis (PD) have a significantly greater death risk tha...
Brain-type (B-type) natriuretic peptide (BNP), a neurohormone synthesized in the cardiac ventricles, can be a sensitive marker for congestive heart failure (CHE). A new rapid BNP immunoassay that measures plasma levels of BNP helps screen patients who presen...
Heart FailureBackground:Autonomic dysfunction is an important component in congestive heart failure (CHF) pathophysiology. The combined effects of reduced ejection fraction and advanced CHF Class on baroreceptor function in CHF have not been well investigated.#Methods:A single center prospective study ...
Congestive heart failure (CHF) is a cardiovascular disease associated with autonomic dysfunction, where sympathovagal imbalance was reported in many studies using heart rate variability (HRV). To learn more about the dynamic interaction in the autonomic
