Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [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 ...
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]
Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3] The main mechanism of coronary artery obstruction is atherosclerosis as part of coronary artery disease. Other causes of angina include abnormal heart rhythms, heart failure and, less commonly, anemia. [4]
Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
Stone heart syndrome (also known as ischemic myocardial contracture) is a rare and severe condition characterized by extreme rigidity and hardness of the heart muscle. This condition typically occurs during high-risk situations such as heart surgery or following a severe heart attack , often leading to life-threatening complications.
The American Heart Association alerted doctors in October about cardiovascular-kidney-metabolic (CKM) syndrome, a condition which affects major organs in the body, including the brain, heart ...
Additionally, the weakened heart muscle may not be able to effectively pump blood to the lungs, leading to the accumulation of fluid in the lungs, a condition known as pulmonary edema. [ 7 ] Another potential complication of alcoholic cardiomyopathy is the development of arrhythmias, or abnormal heart rhythms. [ 7 ]
