What anatomically predisposes the LAD to be occluded more so than the other coronary arteries?

What anatomically predisposes the LAD to be occluded more so than the other coronary arteries?

Biggest: It's the biggest of the 3 coronaries thus sees more volume of blood. Because of its bifurcation from the l main, it's also is exposed to proximal turbulence. Both factors may be injurious to its endothelium. Finally, because of its size & the muscle i subserves, it's more obvious: when the lad occludes, you know it-so there is bias in the studies of its incidence. ...Read more

Can stent be used to open 100% blockage in an artery such as LAD during cardiac catheterization procedure . Cons and pros please. Thank.

Can stent be used to open 100% blockage in an artery such as LAD during cardiac catheterization procedure . Cons and pros please. Thank.

Yes, if needed: Total blockage may occur suddenly - this is what causes a heart attack. Then the goal of the procedure is to get the blocked artery open asap (<90min) to save otherwise dying heart muscle. If the blockage is chronic, then it should be opened if the supplied muscle is alive and the patient's active lifestyle brings out symptoms. Stress scanning may be helpful to determine this. ...Read more

Long term is tegretol or lamictal safer for a cardiac patient? 2 stents in LAD artery.

Long term is tegretol or lamictal safer for a cardiac patient? 2 stents in LAD artery.

Both fairly safe,: Yet, i would tend not to use tegretol due to its potential for adverse effects, such as lowering sodium, causing bone marrow anemias, affecting liver function, but also raising cholesterol levels (which indirectly might harm the heart eventually). Big issue with Lamictal is occasional rash, but otherwise, not a bad choice and well tolerated. ...Read more

Coronary Artery (Definition)
