Cardiology. 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 ...
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 ]
Stage A Defined as: At high risk for heart failure but without structural heart disease (defects in the heart from aging, injury, infection, or heart defect at birth), or symptoms of heart failure.
Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [ 11][ 1] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose consciousness.
A myocardial infarction ( MI ), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [ 1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [ 1]
Feb. 13—Sweating, nausea, dizziness and unusual fatigue may not sound like typical heart attack symptoms. However, they are common for women and may occur more often when resting or asleep.
Cardiology. Heart failure with preserved ejection fraction ( HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [ 1 ...
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 ...
