In this case, congestive heart failure may represent underlying anemia (eg, Rh sensitization, fetal-maternal transfusion), arrhythmias (usually supraventricular tachycardia), or myocardial dysfunction (myocarditis or cardiomyopathy). (medscape.com)
[ 2 ] Systolic dysfunction is characterized by diminished ventricular contractility that results in an impaired ability to increase the stroke volume to meet systemic demands. (medscape.com)
Factors such as anatomic stresses (eg, coarctation of the aorta) that contribute to an increased afterload (end-systolic wall stress), as well as neurohormonal factors that increase systemic vascular resistance, also lead to systolic dysfunction. (medscape.com)
Diastolic dysfunction results from decreased ventricular compliance, necessitating an increase in venous pressure to maintain adequate ventricular filling. (medscape.com)
Causes of primary diastolic dysfunction include an anatomic obstruction that prevents ventricular filling (eg, pulmonary venous obstruction), a primary reduction in ventricular compliance (eg, cardiomyopathy, transplant rejection), external constraints (eg, pericardial effusion), and poor hemodynamics after the Fontan procedure (eg, elevated pulmonary vascular resistance). (medscape.com)
The main pathophysiological correlate is impaired left ventricular filling, resulting in diastolic dysfunction with increased end-diastolic left ventricular pressure ( P LV,ED ), with consequent pulmonary congestion, increased stimulation of pulmonary vagal irritant receptors (J-receptors) and enhanced chemosensitivity of central and peripheral carbon dioxide receptors. (ersjournals.com)

Diastolic dysfunction is the predominant cardiac abnormality in this syndrome, which is associated with increased risk of hospitalisation and death. (bmj.com)
Indeed, such a definition of diastolic HF has been adopted by the majority of previous reports, w5 and is supported by the results of recent studies which indicate that the presence of diastolic dysfunction may be assumed in patients presenting with HF and normal LV ejection fraction (LVEF). (bmj.com)
Nonetheless, a recent review has highlighted the disconnect between Doppler echo measurements and true diastolic properties of the left ventricle, and has questioned the prevailing assumption that HF with preserved systolic function is always caused by diastolic dysfunction. (bmj.com)
w8 For these reasons, recent guidelines have called for invasive determination of diastolic dysfunction to make a definite diagnosis of diastolic HF, 6 although the feasibility of this approach is limited. (bmj.com)
Echocardiographic assessment of diastolic function makes the diagnosis of diastolic HF more specific, allows serial assessment of the response of diastolic dysfunction to treatment, and facilitates inclusion of more homogeneous populations into intervention trials. (bmj.com)

Heart Failure is a condition in which heart will not be able to pump good amounts of blood to meet up with the demands of the body i.e. metabolic demands. (indexofsciences.com)
The pumping action of the heart is that it moves oxygen and nutrient-rich blood to the left atrium and then to the left ventricle from the lungs, which then pushes the blood to different parts of the body. (indexofsciences.com)
The force of the heart is not enough for the blood to be pushed into the circulation. (indexofsciences.com)
The heart is not filled with proper blood, in between the heartbeats i.e. the resting period. (indexofsciences.com)

Heart failure (HF) is a common cardiovascular disease that has a great impact on public health, with high medical costs, morbidity, and mortality [ 1 , 2 ]. (hindawi.com)
Heart disease has a high mortality and morbidity worldwide. (frontiersin.org)
Among birth defects, congenital heart disease is the leading cause of infant mortality. (msdmanuals.com)

This damage may result from conditions present at birth (such as congenital cardiomyopathy or abnormalities in the formation of the heart chambers) or it may be due to infections or other conditions encountered in youth or adulthood. (harvard.edu)
More recently, I think people are realizing that many of the abnormalities in ventilation that we see in sleep apnea, also occur in heart failure - and we see this frequently in our cardiometabolic exercise lab. (itamar-medical.com)

As the heart works harder to meet normal metabolic demands, the amount cardiac output can increase in times of increased oxygen demand (e.g., exercise) is reduced. (wikipedia.org)
citation needed] A common finding in those with heart failure is an increased heart rate, stimulated by increased sympathetic activity in order to maintain an adequate cardiac output. (wikipedia.org)
The general effect is one of reduced cardiac output and increased strain on the heart. (wikipedia.org)
Binding to beta-1 receptors in the myocardium increases the heart rate and makes contractions more forceful in an attempt to increase cardiac output. (wikipedia.org)

Although TOPCAT did not significantly decrease the combined endpoint or cardiovascular death, spironolactone is the first drug shown to reduce heart failure hospitalizations in this vulnerable population," said Brigham and Women's Hospital's Dr. Marc Pfeffer, the principal investigator. (scienceblog.com)
It combines a decrease in heart rate and the stigma of tissue hypoxia, in the absence of signs of hypovolemia. (scirp.org)

Heart transplant may be needed in some cases. (hdkino.org)
If your heart issues don't get better with medications, devices, or other surgeries, you may be a candidate for a heart transplant . (uvahealth.com)
In a heart transplant, the diseased heart is replaced with a healthy, working heart from a someone else (a donor). (uvahealth.com)

The lower reading (known as diastolic ) measures the force of contractions and relaxation. (healthinternetwork.org)

and diastolic or right-sided heart failure. (medicinenet.com)

Among the Elderly, Heart Failure remains the main cause of hospitalization. (indexofsciences.com)
We're less likely to think of heart failure, though it affects more than 2.5 million women and is the leading reason for hospitalization (and a major cause of death) in women over 65. (harvard.edu)
In the current trial, spironolactone did not improve the combined primary endpoints of cardiovascular death, hospitalization for heart failure, or aborted cardiac arrest. (scienceblog.com)
The other method required looked at a person's history of heart failure hospitalization within the last year. (scienceblog.com)

Fluid retention is another common symptom of heart failure. (pc-mobile.net)
This symptom can be an indicator of heart failure, and it's essential to monitor weight changes closely. (pc-mobile.net)

The chronically high levels of circulating neuroendocrine hormones such as catecholamines, renin, angiotensin, and aldosterone affect the myocardium directly, causing structural remodelling of the heart over the long term. (wikipedia.org)

One method required looked for elevated levels of the hormone BNP, which is associated with more severe heart failure. (scienceblog.com)
Heart failure can manifest in a variety of ways, and its symptoms can range from mild to severe. (pc-mobile.net)
