  2. Myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Myocardial_infarction

    A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]

  3. Acute coronary syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_coronary_syndrome

    STEMI is characterized by complete blockage of a coronary artery resulting in necrosis of part of the heart muscle indicated by ST elevation on ECG, NSTEMI is characterized by a partially blocked coronary artery resulting in necrosis of part of the heart muscle that may be indicated by ECG changes, and unstable angina is characterised by ...

  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.

  5. Door-to-balloon - Wikipedia

    en.wikipedia.org/wiki/Door-to-balloon

    Door-to-balloon is a time measurement in emergency cardiac care (ECC), specifically in the treatment of ST segment elevation myocardial infarction (or STEMI). The interval starts with the patient's arrival in the emergency department, and ends when a catheter guidewire crosses the culprit lesion in the cardiac cath lab.

  6. 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 ...

  7. Wikipedia : Osmosis/Myocardial infarctions

    en.wikipedia.org/wiki/Wikipedia:Osmosis/...

    Heart attacks happen when these small arteries become blocked and stop supplying blood to the heart tissue, and if this happens for long enough, heart tissue dies. Almost all heart attacks are ultimately a result of endothelial cell dysfunction, which relates to anything that irritates or inflames the slippery inner lining of the artery—the ...

  8. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    This is known as myocardial infarction. [9] A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25] Coronary ischemia resulting from coronary artery disease also increases the risk of developing heart failure. [10] Most cases of heart failure result from underlying coronary artery disease. [10]

  9. Chest pain - Wikipedia

    en.wikipedia.org/wiki/Chest_pain

    A blockage of coronary arteries can lead to a heart attack. Acute coronary syndrome. Stable or unstable angina; Myocardial infarction ("heart attack"): People typically present with pressure or squeezing sensation over the chest in addition to sweating, nausea, vomiting, and weakness. [1]
