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]
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] this may be measured by echocardiography or cardiac catheterization.
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 ...
What is heart failure? If ever there were a prize awarded for “most misleading name given to a medical condition,” heart failure would win hands down. “Heart failure (also called congestive ...
The term “heart failure” refers to problems with the heart muscle’s ability to pump blood. These problems can deprive other parts of the body of sufficient oxygen and blood.
Ultimately the ventricle walls need to be the right size relative to the size of the chamber in order for the heart to work effectively. Any major deviation from that can lead to heart failure. Alright, even though systolic failure is most common in left-sided heart failure, diastolic heart failure or filling dysfunction can also happen.
