  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. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Cardiac arrest. Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [11] [1] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose ...

  4. Coronary thrombosis - Wikipedia

    en.wikipedia.org/wiki/Coronary_thrombosis

    Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis, a buildup of cholesterol and fats in the artery walls. The smaller vessel diameter allows less blood to flow and facilitates progression to a myocardial infarction. Leading risk factors for coronary thrombosis are high low-density lipoprotein cholesterol ...

  5. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    Coronary ischemia, myocardial ischemia, [1] or cardiac ischemia, [2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [3] Coronary ischemia is linked to heart disease, and heart attacks. [4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [5]

  6. Cyanide poisoning - Wikipedia

    en.wikipedia.org/wiki/Cyanide_poisoning

    If hydrogen cyanide is inhaled, it can cause a coma with seizures, apnea, and cardiac arrest, with death following in a matter of seconds. At lower doses, loss of consciousness may be preceded by general weakness, dizziness, headaches, vertigo, confusion, and perceived difficulty in breathing.

  7. Ventricular fibrillation - Wikipedia

    en.wikipedia.org/wiki/Ventricular_fibrillation

    Ventricular fibrillation ( V-fib or VF) is an abnormal heart rhythm in which the ventricles of the heart quiver. [2] It is due to disorganized electrical activity. [2] Ventricular fibrillation results in cardiac arrest with loss of consciousness and no pulse. [1] This is followed by sudden cardiac death in the absence of treatment. [2]

  8. Atherosclerosis - Wikipedia

    en.wikipedia.org/wiki/Atherosclerosis

    In 2004, US data indicated that in ~66% of men and ~47% of women, the first symptom of atherosclerotic cardiovascular disease was a heart attack or sudden cardiac death (defined as death within one hour of onset of the symptom). Case studies have included autopsies of U.S. soldiers killed in World War II and the Korean War. A much-cited report ...
