Researchers are trying learn more about how the heart and blood volume interact in subjects with heart failure and how measuring blood volume may help them develop better ways of treating and managing heart failure patients.

Heart failure is a common cardiac condition affecting nearly 6 million Americans. Silent blood volume overload is common in patients with heart failure and is associated with increased ris...
The purpose of this study is to better understand blood volume status and whether knowledge of it can change and improve heart failure care.
Congestive heart failure is a condition in which the heart is weakened and is unable to pump enough blood to the organs of the body to meet the demands of the body. At times there may be ...
Heart failure has become one of the major epidemics of the modern era. Despite optimal standard drug therapy, the prognosis of patients with heart failure remains poor. Patient with Heart...
Researchers are observing the values of proEnkephalin (PENK) via a blood draw in hospitalized patients that are volume overloaded requiring diuresis. If changes in PENK are found, physicia...
Congestion is a marker of adverse prognosis in patients with heart failure (HF). In addition to brain natriuretic peptide (BNP), estimated plasma volume status (ePVS), bioimpedance vector analysis (BI...
We aimed to investigate whether metabolomic profiling of blood can lead to novel insights into heart failure pathogenesis or improved risk prediction.
Fluid overload is common in heart failure (HF) and obesity; however, the relationship between the extent of intravascular volume expansion and indices such as BMI in obese and non-obese HF patients ha...
Plots of blood volume measurements over time (profiles) may identify euvolemia during fluid removal for acute heart failure. We assessed agreement between two noninvasive measurements of blood volume ...
Heart failure (HF) is classified into three types according to left ventricular ejection fraction (EF). The effect of blood pressure (BP) on the pathogenesis of each type is assumed to be different. H...
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
The amount of BLOOD pumped out of the HEART per beat not to be confused with cardiac output (volume/time).
