  2. Unstable angina - Wikipedia

    en.wikipedia.org/wiki/Unstable_angina

    The pathophysiology of unstable angina is controversial. Previously, unstable angina was assumed to be angina pectoris caused by disruption of an atherosclerotic plaque with partial thrombosis and possibly embolization or vasospasm leading to myocardial ischemia. [9] [10] However, sensitive troponin assays reveal rise of cardiac troponin in the ...

    Information card published by the National Heart, Lung, and Blood Institute urging people with symptoms of angina to call the emergency medical services..

  4. Coronary ischemia - Wikipedia

    en.wikipedia.org/wiki/Coronary_ischemia

    Angina may present typically with classic symptoms or atypically with symptoms less often associated with heart disease. [19] Atypical presentations are more common in women, diabetics, and elderly individuals. [8] Angina may be stable or unstable. Unstable angina is most often associated with emergent, acute coronary syndromes. [20]

  5. Acute coronary syndrome - Wikipedia

    en.wikipedia.org/wiki/Acute_coronary_syndrome

    In unstable angina, symptoms may appear on rest or on minimal exertion. [6] The symptoms can last longer than those in stable angina, can be resistant to rest or medicine, and can get worse over time. [8] [10] Though ACS is usually associated with coronary thrombosis, it can also be associated with cocaine use. [11]

  6. Kounis syndrome - Wikipedia

    en.wikipedia.org/wiki/Kounis_syndrome

    This interferes with the blood flow to the heart muscle and causes symptoms otherwise indistinguishable from unstable angina. [8] It is possible that even in people without direct evidence of allergy, the allergic response may be playing a role in acute coronary syndrome: markers of mast cell activation are found in people with ACS. [8]

    en.wikipedia.org/wiki/Angina

    Unstable angina (UA) (also "crescendo angina"; this is a form of acute coronary syndrome) is defined as angina pectoris that changes or worsens or begins suddenly at rest. [12] Unstable angina is a medical emergency and requires urgent medical treatment from a doctor. [5] It has at least one of these three features: [13]

  8. 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.
