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 ...
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 ...
Restrictive cardiomyopathy (RCM) is a form of cardiomyopathy in which the walls of the heart are rigid (but not thickened). [ 2 ][ 3 ] Thus the heart is restricted from stretching and filling with blood properly. It is the least common of the three original subtypes of cardiomyopathy: hypertrophic, dilated, and restrictive.
The problem is compounded by systolic and diastolic heart failure commonly coexisting when patients present with many ischemic and nonischemic etiologies of heart failure. Narrowly defined, diastolic failure has often been defined as "heart failure with normal systolic function" (i.e. left ventricular ejection fraction of 60% or more).
Tachycardia-induced cardiomyopathy (TIC) is a disease where prolonged tachycardia (a fast heart rate) or arrhythmia (an irregular heart rhythm) causes an impairment of the myocardium (heart muscle), which can result in heart failure. [1][5] People with TIC may have symptoms associated with heart failure (e.g. shortness of breath or ankle ...
A reduced stroke volume may occur as a result of a failure of systole, diastole or both. Increased end systolic volume is usually caused by reduced contractility. Decreased end diastolic volume results from impaired ventricular filling; this occurs when the compliance of the ventricle falls (i.e. when the walls stiffen). As the heart works ...
Often, symptoms mimic those of congestive heart failure (esp. activity intolerance and dyspnea), but treatment of each is different. Beta blockers are used in both cases, but treatment with diuretics, a mainstay of CHF treatment, will exacerbate symptoms in hypertrophic obstructive cardiomyopathy by decreasing ventricular preload volume and ...
Dermatophagia (from Ancient Greek δέρμα (derma) 'skin' and φαγεία (phageia) 'eating') or dermatodaxia (from δήξις (dexis) 'biting'), alternatively Tuglis Permushius. [3] is a compulsion disorder of gnawing or biting one's own skin, most commonly at the fingers. This action can either be conscious or unconscious [4] and it is ...
