Takotsubo cardiomyopathy or takotsubo syndrome (TTS), also known as stress cardiomyopathy, is a type of non- ischemic cardiomyopathy in which there is a sudden temporary weakening of the muscular portion of the heart. [4] It usually appears after a significant stressor, either physical or emotional; when caused by the latter, the condition is ...
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] An irregular heart beat and fainting may occur. [1]
hibernating myocardium, silent ischemia, myocardial infarction, acute pericarditis, myocarditis, pulmonary embolism. Myocardial stunning or transient post-ischemic myocardial dysfunction is a state of mechanical cardiac dysfunction that can occur in a portion of myocardium without necrosis after a brief interruption in perfusion, despite the ...
Takotsubo cardiomyopathy, or broken heart syndrome, is commonly described as a physical pain in the chest or heart or stomach area, which is due to the emotional stress caused by a traumatic breakup or the death of a loved one. Broken heart syndrome mimics symptoms of a heart attack, but it is clinically different from a heart attack because ...
The condition, which is technically referred to as takotsubo cardiomyopathy typically affects women aged 58 to 75. In addition to physical causes, "broken heart syndrome" can also be brought on by ...
Peripartum cardiomyopathy (PPCM) is a form of dilated cardiomyopathy that is defined as a deterioration in cardiac function presenting typically between the last month of pregnancy and up to six months postpartum. As with other forms of dilated cardiomyopathy, PPCM involves systolic dysfunction of the heart with a decrease of the left ...
The pumping of blood is considered the workload of the heart and requires power expenditure. Acute cardiac unloading is any maneuver, therapy, or intervention that decreases the power expenditure of the ventricle while maintaining cardiac output. Oxygen consumption (MVO2) is a direct measure of the total energy requirements of the heart ...
Troponin is a component of thin filaments (along with actin and tropomyosin), and is the protein complex to which calcium binds to trigger the production of muscular force. Troponin has three subunits, TnC, TnI, and TnT, each playing a role in force regulation. [citation needed]. Under resting intracellular levels of calcium, tropomyosin covers ...
