2. Right coronary artery - Wikipedia

   en.wikipedia.org/wiki/Right_coronary_artery

   The right coronary artery supplies oxygenated blood to the right atrium, the right ventricle, and the posterior third and inferior end of the interventricular septum. [ 2 ] [ 5 ] It may also supply 25% to 35% of the left ventricle (LV).

3. Coronary arteries - Wikipedia

   en.wikipedia.org/wiki/Coronary_arteries

   Ramus or intermediate artery; Right coronary artery. Right marginal artery; Posterior descending artery; The left coronary artery arises from the aorta within the left cusp of the aortic valve and feeds blood to the left side of the heart. It branches into two arteries, the left anterior descending and the left circumflex.

4. Coronary artery disease - Wikipedia

   en.wikipedia.org/wiki/Coronary_artery_disease

   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]

5. Coronary circulation - Wikipedia

   en.wikipedia.org/wiki/Coronary_circulation

   The right coronary artery proceeds along the coronary sulcus and distributes blood to the right atrium, portions of both ventricles, and the heart conduction system. Normally, one or more marginal arteries arise from the right coronary artery inferior to the right atrium. The marginal arteries supply blood to the superficial portions of the ...

6. Coronary ischemia - Wikipedia

   en.wikipedia.org/wiki/Coronary_ischemia

   Coronary ischemia and coronary artery disease are contributors to the development of heart failure over time. [10] Diagnosis of coronary ischemia is achieved by an attaining a medical history and physical examination in addition to other tests such as electrocardiography (ECG), stress testing , and coronary angiography . [ 11 ]

7. Outline of cardiology - Wikipedia

   en.wikipedia.org/wiki/Outline_of_cardiology

   Atherosclerosis of a coronary artery leads to coronary artery disease (CAD). Atherosclerosis is a broad term referring to loss of elasticity of arteries and more specific terms exist — arteriosclerosis and arteriolosclerosis — to narrow which arteries are diseased and can easily be confused due to similar spelling. Overall, atherosclerosis ...

8. Atrioventricular node - Wikipedia

   en.wikipedia.org/wiki/Atrioventricular_node

   The origin of this artery is most commonly (80–90% of hearts) a branch of the right coronary artery, with the remainder originating from the left circumflex artery. [4] [5] [6] This is associated with the dominance of the coronary artery circulation.

9. Coronary occlusion - Wikipedia

   en.wikipedia.org/wiki/Coronary_occlusion

   A coronary occlusion, or coronary artery disease, is the partial or complete obstruction of blood flow in a coronary artery. This condition was first discussed in 1910 by Sir William Osler . [ 1 ] This condition slows or blocks the supply of oxygen-rich blood to the heart . [ 2 ]
