Why do people get blocked veins and arteries?

Why do people get blocked veins  and arteries?

Family DNA: Arteries become blocked with arteriosclerosis, and it tends to run in the family, and diet/lifestyle contributes to the progression. Veins become blocked with blood clots, and heredity can make one more prone to development of blood clots. Venous clots occur in the deep and superficial veins, and the former type requires anticoagulation. Prolonged travel, surgery are risk factors for clots. ...Read more

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more

How long does it take the body to make a new vein or artery around a blocked one?

How long does it take the body to make a new vein or artery around a blocked one?

Not the way: In most parts of the body, there are redundant elements of the blood supply, so that if one vessel is blocked, the others already present take over. New vessels are not grown to jump over the blockage. This is not true for the brain and back of the eye where blocked vessels create permanent damage as collateral vessel are not present in these tissues. ...Read more

If i by mistake cut a vein/artery how fast do I need to get to the hospital before it's too late?

If i by mistake cut a vein/artery how fast do I need to get to the hospital before it's too late?

Depends.: A vein is a low pressure system and an artery is a high pressure system. Most venous bleeding except the larger major veins can be controlled with elevation and direct pressure. Arteries, on the other hand, because of the high pressure may not stop with pressure alone. If a vein is cut you should have ample time to get to a hospital. If an artery is cut, get to a hospital as soon as you can. ...Read more

When it comes to healthy eating, would already damaged/clogged veins and arteries get better over time?

When it comes to healthy eating, would already damaged/clogged veins and arteries get better over time?

Complicated question: 1st, veins and arteries behave differently and can't be lumped together. 2nd, vein disease is usually not affected by diet 3rd, artery disease can be made worse with bad eating habits but smoking and diabetes do more damage to your arteries than diet (generally speaking). ...Read more

100 % blocked artery I have 1 artery that is 100% blocked and 2 that is 50% blocked.I'm with the va and they said the 100% blocked artery rerouted two little veins to the bottom of my heart and kind of repaired itself.They are also 50% blocked and too sma

It's : It's a very good question. There are times when we (as cardiologists) will send a patient for bypass surgery of a single 100% blocked vessel, especially if it is the artery on the front of the heart (left anterior descending) and especially if heart muscle function is depressed (ejection fraction). However, if heart muscle function is good and the body has made its own small bypass vessels (collateral arteries) we will often manage single vessel disease like you describe medically. It is then critically important that the other arteries stay healthy since part of the backup system is now gone. Medical management should include drugs that lower the risk of heart attack and plaque progression. Aggressive treatment of cholesterol elevation is critically important. You should also know that surgery is generally pursued to decrease the risk of death or to improve symptoms that can't be controlled medically, and your risk of death may not be high enough to justify the risk of surgery. Surgery does not generally reduce the risk of heart attack though (in the right circumstances) it can make heart attacks more survivable. Although i don't know enough about your condition to give you a definite personal answer, the situation you describe is not unusual. I will say, however, that treatment of your heart disease must include careful attention to minimizing your risk of plaque progression and plaque rupture (i.e. Heart attack), which will likely involve aggressive therapy with statins and/or other cholesterol lowering medications. ...Read more

What happens if you get a blood clot in the leg (vein), can it cause a stroke (artery)?

What happens if you get a blood clot in the leg (vein), can it cause a stroke (artery)?

Maybe: If you have thrombophlebitis, a clot could go directly to the lung causing a life threatening pulmonary embolism. But if there is a congenital hole within the heart, such as patent foramen ovale, the embolism can be paroxysmal and go to brain, causing a stroke. Anti-coagulation can be protective in these circumstances. ...Read more

I'm just wondering, if you get a blood clot in the leg (vein), can it cause a stroke (artery)?

Paradoxical stroke: As dr. Santin said, it is possible but fairly rare. Although 25-30% of the population has the septal defect in their heart that he mentioned, it rarely causes trouble when it is there. As a result, we don't routinely look for it, unless someone has had a stroke and, especially, if they are young and don't have other risk factors for having had a stroke. ...Read more
