Heart failure (HF), also known as congestive heart failure (CHF), is a syndrome caused by an impairment in the heart 's ability to fill with and pump blood. Although symptoms vary based on which side of the heart is affected, HF typically presents with shortness of breath, excessive fatigue, and bilateral leg swelling. [ 3 ]
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing (dyspnea), leg or feet swelling, and fatigue. [ 1 ] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs ...
People with heart failure, also known as congestive heart failure (CHF), are educated to undertake various non- pharmacological measures to improve symptoms and prognosis. Such measures include: [ 1 ] Moderate physical activity, when symptoms are mild or moderate; or bed rest when symptoms are severe. In individuals with heart failure ...
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
Cardiac contractility modulation. Cardiac contractility modulation is a therapy which is intended for the treatment of patients with moderate to severe heart failure (NYHA class II–IV) with symptoms despite optimal medical therapy who can benefit from an improvement in cardiac output. The short- and long-term use of this therapy enhances the ...
Major adverse cardiovascular events. Major adverse cardiovascular events (MACE, or major adverse cardiac events) is a composite endpoint frequently used in cardiovascular research. [1][2] Despite widespread use of the term in clinical trials, the definitions of MACE can differ, which makes comparison of similar studies difficult.
Cardiac index is a critical parameter in evaluating cardiac performance and the adequacy of tissue perfusion. In healthy adults, the normal range of cardiac index is generally between 2.6 to 4.2 L/min/m². Values below this range may indicate hypoperfusion and are often seen in conditions such as heart failure, hypovolemia, and cardiogenic ...
Killip class. The Killip classification is a system used in individuals with an acute myocardial infarction (heart attack), taking into account physical examination and the development of heart failure in order to predict and stratify their risk of mortality. Individuals with a low Killip class are less likely to die within the first 30 days ...
