  2. List of circulatory system conditions - Wikipedia

    en.wikipedia.org/wiki/List_of_circulatory_system...

    This is an incomplete list, which may never be able to satisfy certain standards for completion.. There are many conditions of or affecting the human circulatory system — the biological system that includes the pumping and channeling of blood to and from the body and lungs with heart, blood and blood vessels.

  3. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    If blood flow through the coronary arteries is stopped completely, cardiac muscle cells may die, known as a myocardial infarction, or heart attack. [9] Coronary artery disease (CAD) is the most common cause of coronary ischemia. [7] Coronary ischemia and coronary artery disease are contributors to the development of heart failure over time. [10]

  4. Hyperthermia - Wikipedia

    en.wikipedia.org/wiki/Hyperthermia

    In severe heat stroke, confusion and aggressive behavior may be observed. Heart rate and respiration rate will increase (tachycardia and tachypnea) as blood pressure drops and the heart attempts to maintain adequate circulation. The decrease in blood pressure can then cause blood vessels to contract reflexively, resulting in a pale or bluish ...

  5. Overheating (electricity) - Wikipedia

    en.wikipedia.org/wiki/Overheating_(electricity)

    When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.

  6. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    When environmental temperature is above core body temperature, sweating is the only physiological way for humans to lose heat. [10] Arteriolar vasodilation occurs. The smooth muscle walls of the arterioles relax allowing increased blood flow through the artery. This redirects blood into the superficial capillaries in the skin increasing heat ...

  7. 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. Coronary occlusion - Wikipedia

    en.wikipedia.org/wiki/Coronary_occlusion

    A coronary occlusion, or coronary artery disease, is the partial or complete obstruction of blood flow in a coronary artery. This condition was first discussed in 1910 by Sir William Osler . [ 1 ] This condition slows or blocks the supply of oxygen-rich blood to the heart . [ 2 ]

  9. Heat syncope - Wikipedia

    en.wikipedia.org/wiki/Heat_syncope

    Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
