  2. Coronary vasospasm - Wikipedia

    en.wikipedia.org/wiki/Coronary_vasospasm

    Coronary vasospasm refers to when a coronary artery suddenly undergoes either complete or sub-total temporary occlusion. [ 1 ] In 1959, Prinzmetal et al. described a type of chest pain resulting from coronary vasospasm, referring to it as a variant form of classical angina pectoris . [ 2 ]

  3. Variant angina - Wikipedia

    en.wikipedia.org/wiki/Variant_angina

    Variant angina, also known as Prinzmetal angina, vasospastic angina, angina inversa, coronary vessel spasm, or coronary artery vasospasm, [2] is a syndrome typically consisting of angina (cardiac chest pain).

  4. Vasospasm - Wikipedia

    en.wikipedia.org/wiki/Vasospasm

    Vasospasm refers to a condition in which an arterial spasm leads to vasoconstriction. This can lead to tissue ischemia (insufficient blood flow) and tissue death ( necrosis ). Along with physical resistance, vasospasm is a main cause of ischemia.

  5. Angina - Wikipedia

    en.wikipedia.org/wiki/Angina

    Organic nitrates are used extensively to treat angina. They improve coronary blood flow of the coronary arteries (arteries which supply blood to the heart muscle) by reversing and preventing vasospasm, which increases the blood flow to the heart, improving perfusion and oxygen delivery to the heart associated with the pain of angina.

  6. Cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Cardiac_arrest

    Coronary vasospasm may result in cardiac arrhythmias, altering the heart's electrical conduction with a risk of complete cardiac arrest from severe or prolonged rhythm changes. Mechanical abnormalities with an associated risk of cardiac arrest may arise from coronary artery dissection, which can be attributed to Marfan Syndrome or trauma. [29]

  7. Coronary catheterization - Wikipedia

    en.wikipedia.org/wiki/Coronary_catheterization

    A coronary catheterization is a minimally invasive procedure to access the coronary circulation and blood filled chambers of the heart using a catheter. It is performed for both diagnostic and interventional (treatment) purposes. Coronary catheterization is one of the several cardiology diagnostic tests and procedures.

  8. Calcium channel blocker - Wikipedia

    en.wikipedia.org/wiki/Calcium_channel_blocker

    Phenylalkylamine calcium channel blockers are relatively selective for myocardium, reduce myocardial oxygen demand and reverse coronary vasospasm, and are often used to treat angina.

  9. 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.
