35% risk of death in first year [10] 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 ...
Diastolic function. In clinical cardiology the term "diastolic function" is most commonly referred as how the heart fills. [1] Parallel to "diastolic function", the term " systolic function" is usually referenced in terms of the left ventricular ejection fraction (LVEF), which is the ratio of stroke volume and end-diastolic volume. [2]
Harmful. 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 ...
Dilated cardiomyopathy (DCM) is a condition in which the heart becomes enlarged and cannot pump blood effectively. [3] Symptoms vary from none to feeling tired, leg swelling, and shortness of breath. [2] It may also result in chest pain or fainting. [2] Complications can include heart failure, heart valve disease, or an irregular heartbeat. [3] [4]
Rheumatic fever (RF) is an inflammatory disease that can involve the heart, joints, skin, and brain. [ 1 ] The disease typically develops two to four weeks after a streptococcal throat infection. [ 2 ] Signs and symptoms include fever, multiple painful joints, involuntary muscle movements, and occasionally a characteristic non- itchy rash known ...
Supplemental oxygen, diuretics, treat underlying disease process. Pulmonary edema (British English: oedema), also known as pulmonary congestion, is excessive fluid accumulation in the tissue or air spaces (usually alveoli) of the lungs. [1] This leads to impaired gas exchange, most often leading to shortness of breath (dyspnea) which can ...
Myocarditis. Other names. Inflammatory cardiomyopathy (infectious) A microscope image of myocarditis at autopsy in a person with acute onset of heart failure. Specialty. Infectious disease, cardiology. Symptoms. Shortness of breath, chest pain, decreased ability to exercise, irregular heartbeat [ 1 ] Complications.
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.
