  2. Variant angina - Wikipedia

    en.wikipedia.org/wiki/Variant_angina

    Variant angina differs from stable angina in that it commonly occurs in individuals who are at rest or even asleep, whereas stable angina is generally triggered by exertion or intense exercise. Variant angina is caused by vasospasm, a narrowing of the coronary arteries due to contraction of the heart's smooth muscle tissue in the vessel walls. [3]

    Unstable angina is a type of angina pectoris [1] that is irregular or more easily provoked. [2] It is classified as a type of acute coronary syndrome. [3]It can be difficult to distinguish unstable angina from non-ST elevation (non-Q wave) myocardial infarction.

[5] Chest pain is more common at certain times of the day, usually from late night to early morning. [6] These episodes can be accompanied by nausea, vomiting, cold sweating, and even syncope.

    All right, as a quick recap…. Angina pectoris is chest pain caused by reduced blood flow resulting in a lack of oxygen in the heart muscle. There are three types: stable angina, unstable angina, and vasospastic angina. Rest tends to relieve stable angina, but not the other two types, and all three can be treated with nitroglycerin.

  7. ST depression - Wikipedia

    en.wikipedia.org/wiki/ST_depression

    ST segment depression and T-wave changes may be seen in patients with unstable angina; Depressed but upsloping ST segment generally rules out ischemia as a cause. Also, it can be a normal variant or artifacts, such as: Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode [3]

    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]
