artery,

blood vessel that conveys blood away from the heartheart,
muscular organ that pumps blood to all parts of the body. The rhythmic beating of the heart is a ceaseless activity, lasting from before birth to the end of life. Anatomy and Function

The human heart is a pear-shaped structure about the size of a fist.

. Except for the pulmonary artery, which carries deoxygenated blood from the heart to the lungs, arteries carry oxygenated blood from the heart to the tissues. The largest arterial trunk is the aortaaorta
, primary artery of the circulatory system in mammals, delivering oxygenated blood to all other arteries except those of the lungs. The human aorta, c.1 in. (2.54 cm) in diameter, originates at the left ventricle of the heart.

, microscopic blood vessel, smallest unit of the circulatory system. Capillaries form a network of tiny tubes throughout the body, connecting arterioles (smallest arteries) and venules (smallest veins).

blood vessel that returns blood to the heart. Except for the pulmonary vein, which carries oxygenated blood from the lungs to the heart, veins carry deoxygenated blood. The oxygen-depleted blood passes from the capillaries to the venules (small veins).

). Other important arteries are the subclavian and brachial arteries of the shoulder and arm, the carotid arteries that lead to the head, the coronary arteries that nourish the heart itself, and the iliac and femoral arteries of the abdomen and lower extremities. The walls of the large arteries have three layers: a tough elastic outer coat, a layer of muscular tissue, and a smooth, thin inner coat. Arterial walls expand and contract with each heartbeat, pumping blood throughout the body. The pulsating movement of blood, or pulsepulse,
alternate expansion and contraction of artery walls as heart action varies blood volume within the arteries. Artery walls are elastic. Hence they become distended by increased blood volume during systole, or contraction of the heart.

In patients with the two-vessel disease, the association most frequently found was in both groups LDA and RCA lesions followed by the association of LDA and LCX lesions.
LCX Digital is a full service digital marketing communications company, that specializes in connecting brands with buyers by engaging and acquiring targeted customers for everything — from major retailers like Kohl's and Walmart to leading CPG brands like P&G, Johnson & Johnson to iconic brands like Nike.
In their study, patients with AF with significant coronary artery disease (involvement of LAD, LCX and RCA) had a 2-fold increased risk of in-hospital mortality and patients with clear evidence of NAF had a 3-fold higher risk of mortality than sinus rhythm patients, although the study did not adjust for the Killip class, an important confounding variable.
In the remaining patients it arises as a branch of the LCX.
However after re-combination there were much more lesions located in LCX distal and ostial position in inconsistent group than that in consistent group (Table-I pless than 0.
IVUS assessments focused primarily on plaque distributions at the ostial LAD and LCX and the distal LMCA via manual pullback at a constant speed.
In this report, diagnostic coronary angiography revealed that the left ventricular apex was supplied by the LCX instead of the LAD.
Among single vessel LAD artery disease was seen in 87% followed by RCA 40%, LCX 36% and LMCA 4%.
At our center, it is common to perform provisional two-stent strategies if LCX ostium is severely jeopardized after one-stent crossover from LM to LAD that is, severe dissection or thrombosis in MI flow <3 grade or residual stenosis ≥80%.
