Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack. [6] Common heart attack symptoms include chest pain or angina, pain or discomfort that spreads to the shoulder, arm, back, neck jaw, teeth or the upper belly, cold sweats, fatigue, heartburn, nausea, shortness of breath, or lightheadedness.
[1] [4] [5] While the disease is commonly found in patients with atherosclerosis and coronary artery disease, it can occur by itself and in both cases, it can cause health problems. The disease can cause the heart tissue to be deprived of blood and die due to decreased blood flow, and blockages due to blood clots or spasms of the blood vessel. [2]
The cardiovascular examination is a portion of the physical examination that involves evaluation of the cardiovascular system. The exact contents of the examination will vary depending on the presenting complaint but a complete examination will involve the heart (cardiac examination), lungs (pulmonary examination), belly (abdominal examination) and the blood vessels (peripheral vascular ...
Cardiovascular disease is the leading cause of death in the world. [7] Ischemic heart disease develops when stenosis and occlusion of coronary arteries develops, leading to reduced perfusion of the cardiac tissues. There is ongoing research exploring techniques that might be able to induce healthy neovascularization of ischemic cardiac tissues ...
Vessel harvesting is a surgical technique that may be used in conjunction with a coronary artery bypass graft (CABG). For patients with coronary artery disease, a vascular bypass may be recommended to reroute blood around blocked arteries to restore and improve blood flow and oxygen to the heart.
Coronary anastomoses are a clinically vital subject: the coronary anastomosis is the blood supply to the heart. The coronary arteries are vulnerable to arteriosclerosis and other effects. Inadequate supply to the heart will lead to chest pains or a heart attack (myocardial infarction). These can be ameliorated by surgical intervention to create ...
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
Normally, nitric oxide then works to promote vasodilation in a blood vessel through its own mechanisms such as inhibiting the release of agents that cause vasoconstriction. [ 12 ] Endothelial dysfunction wherein there is a deficiency in the production of nitric oxide has been found to be associated with coronary vasospasm in some but not all ...
