Microvascular angina is a type of angina pectoris in which chest pain and chest discomfort occur without signs of blockages in the larger coronary arteries of their hearts when an angiogram (coronary angiogram) is being performed. [66] [67] The exact cause of microvascular angina is unknown.
An anginal equivalent is a symptom such as shortness of breath , diaphoresis (sweating), extreme fatigue, or pain at a site other than the chest, occurring in a patient at high cardiac risk. Anginal equivalents are considered to be symptoms of myocardial ischemia .
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.
