  2. Myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Myocardial_infarction

    Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.

  3. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    Coronary arteries deliver oxygen-rich blood to the heart muscle. [5] Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ...

  4. Coronary thrombosis - Wikipedia

    en.wikipedia.org/wiki/Coronary_thrombosis

    Coronary thrombosis is defined as the formation of a blood clot inside a blood vessel of the heart. This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack.

    A heart attack occurs when blood flow to the heart muscle is blocked or restricted, usually because an artery has a buildup of plaque. Heart attacks can be sudden, but they can also start with ...

  6. Ischemic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Ischemic_cardiomyopathy

    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.

  8. Frank–Starling law - Wikipedia

    en.wikipedia.org/wiki/Frank–Starling_law

    The Frank-Starling mechanism occurs as the result of the length-tension relationship observed in striated muscle, including for example skeletal muscles, arthropod muscle [4] and cardiac (heart) muscle. [5] [6] [7] As striated muscle is stretched, active tension is created by altering the overlap of thick and thin filaments. The greatest ...

  9. Coronary artery disease - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_disease

    Limitation of blood flow to the heart causes ischemia (cell starvation secondary to a lack of oxygen) of the heart's muscle cells. The heart's muscle cells may die from lack of oxygen and this is called a myocardial infarction (commonly referred to as a heart attack). It leads to damage, death, and eventual scarring of the heart muscle without ...
