Intermittent claudication is a symptom and is by definition diagnosed by a patient reporting a history of leg pain with walking relieved by rest. However, as other conditions such as sciatica can mimic intermittent claudication, testing is often performed to confirm the diagnosis of peripheral artery disease .
A myocardial infarction (MI), or heart attack, arises from complete occlusion of a coronary artery. [9] The most frequent cause of MI is the rupturing of an atherosclerotic plaque formed in CAD. Plaque rupture exposes the subendothelial matrix beneath the plaque, initiating thrombus formation within the vasculature. [ 7 ]
Claudication is a medical term usually referring to impairment in walking, or pain, discomfort, numbness, or tiredness in the legs that occurs during walking or standing and is relieved by rest. [1] The perceived level of pain from claudication can be mild to extremely severe.
As a result, most myocardial perfusion occurs during heart relaxation when the subendocardial coronary vessels are open and under lower pressure. Flow never comes to zero in the right coronary artery, since the right ventricular pressure is less than the diastolic blood pressure. [6]
Peripheral artery disease (PAD) is a vascular disorder that causes abnormal narrowing of arteries other than those that supply the heart or brain. [5] [15] PAD can happen in any blood vessel, but it is more common in the legs than the arms. [16]
Because blockage of arteries is a gradual process, it doesn't happen all at once, and because the blockage is slow, the symptoms are also slow.” ... which occurs when an artery in the heart ...
Atherosclerosis is the most common cause of stenosis (narrowing of the blood vessels) of the heart's arteries and, hence, angina pectoris. Some people with chest pain have normal or minimal narrowing of heart arteries; in these patients, vasospasm is a more likely cause for the pain, sometimes in the context of Prinzmetal's angina and syndrome X.
The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart.
