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]
Also known as 'effort angina', this refers to the classic type of angina related to myocardial ischemia.A typical presentation of stable angina is that of chest discomfort and associated symptoms precipitated by some activity (running, walking, etc.) with minimal or non-existent symptoms at rest or after administration of sublingual nitroglycerin. [11]
With increased metabolic demands (e.g. exercise) such individuals may develop subendocardial or myocardial ischemia due to increased myocardial oxygen demand and seek medical help with symptoms of exercise induced angina. [citation needed]
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]
Conditions that incriminate Kounis syndrome include bronchial asthma, eosinophilic granulomatosis with polyangiitis, serum sickness, scombroid syndrome, angioedema, hay fever, anaphylaxis (exercise induced or idiopathic), and anisakiasis. Coronary stenting, a common procedure used in coronary artery disease patients has also been found to be a ...
Getting regular physical activity to support your cardiovascular health — the AHA recommends at least 150 minutes of moderate-intensity exercise or 75 minutes of intense exercise per week ...
A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
Stable angina (exercise-induced) – diltiazem increases coronary blood flow and decreases myocardial oxygen consumption, secondary to decreased peripheral resistance, heart rate, and contractility. [15] [16] Variant angina – it is effective owing to its direct effects on coronary dilation.
