Heart failure (HF) is primarily a clinical diagnosis that develops secondary to either left ventricular (LV) systolic and diastolic dysfunctions. Despite significant advancements in medical therapies designed to both prevent HF development and treat HF once established, the prognosis of patients after their first hospital admission is poor. Worldwide, 2% to 17% of patients die during their firs...

OBJECTIVE To determine pulmonary capillary filtration in experimental chronic heart failure and to investigate some morphological and haemodynamic mechanisms that could account for reduced filtration in lungs adapted to chronic heart failure. METHODS We studied pulmonary capillary filtration, vascular resistances and morphology in lungs from guinea-pigs adapted to chronic heart failure. Heart...

BACKGROUND Despite its high prevalence, similar symptoms and symptom burden, people suffering from chronic heart failure receive less palliative care than patients with malignant diseases. Internationally, numerous barriers to palliative care of patients with chronic heart failure are known, however, there are no credible data regarding barriers and facilitators to palliative care of people suf...

heart failure is a clinical syndrome characterized by the inability of the heart to provide nutrient supply to tissues. in 75% of cases, the underlying pathology causing heart failure in patients with cardiac death is coronary heart disease. a rabbit model of heart failure with coronary ligation was produced to mimic coronary heart disease in humans. after producing the model, two arteries and ...

BACKGROUND Chronic heart failure is associated with increased sympathetic nerve activity and elevated plasma neuropeptide Y levels. The aim of this study was to investigate whether increased neuropeptide Y release altered vascular neuropeptide Y responses in the dorsal hand veins in patients with chronic heart failure. METHODS AND RESULTS Neuropeptide Y responsiveness was studied in vivo with...

PURPOSE To evaluate the ophthalmic artery hemodynamics in patients with chronic heart failure. METHODS Doppler parameters of ophthalmic artery of 18 patients with chronic heart failure in different stages of the disease were compared with 21 healthy volunteers (control group). These parameters were also correlated with echocardiographic assessments and clinical cardiologic status. RESULTS M...
