What do you call the condition when your heart grows extra veins when another vein is blocked?

Question

I was watching Dr. G and she was talking about a condition when your heart will grow additional veins for blood flow if one of the major veins gets clogged or is not flowing properly. Does anyone know the name of that condition?

Answer 1

"Collaterals"/ or collateral vascularization also known as revascularization , it takes about six to eight weeks, to complete the scarred area, of heart.
Some call it Neovascularization too.

Answer 2

Arteries, not veins.

Arteriogenesis or angiogenesis, besides collateralization.

It is not fast at all according to the cardiology team that did my first angiogram and my triple bypass the next day. I have no large collateral arteries, but full collateralization of my heart at a capillary level. They said they can take years to form, just like the blockages

If the collaterals are open at rest, a person is normally having a heart attack, or near to one. While under anasthesia during my angiogram, my collaterals gave a picture of my entire heart. Nurses referred to me as the miracle man.

A co-workers' husband has a fully blocked artery, with a big collateral artery, or arterial web, going around it. He did not need a bypass. It stays open all the time.

The collaterals form in response to insufficient blood flow. What they do after surgery seems to vary. The bigger ones can stay open, but may close in a few days since there is reduced pressure to keep them open, stolen by the bypass that connects to the aorta ahead of the collateral. Insufficient pressure to hold it open is the theory.

After my bypass operation, I have light angina if I do not warmup before exercising. Seems my collaterals were closed. But with a good long warmup, I have no angina, and it seems no cardiac restrictions at all, so my collateral capillaries are probably open again. I've even pushed my heart rate while rowing to 100% (176) painlessly, with no breathlessness for short periods. But they close when I slow down, and my heart does not resume a resting heart rate for an hour or more, normally not a good thing.

Answer 3

I have heard from coaches and athletes that sprints can force extra veins to grow around the heart. An example of one exercise is to walk very slowly for 100 yards and then run as fast as you can for 100 yards and repeat. And try to control your breathing down. They claim you have to do this every day for at least a year.

Answer 4

Collateralization. We are even studying medicines now that would encourage an increase in collateral vessels in parts of the heart that have blocked vessels. In a few years we may be able to treat heart attacks and heart failure by injecting medicines that encourage formation of collateral vessels in the heart.

Answer 5

Colateral circulation ,which occurs usually with age ,and it is brought about over time generally because the individual has had a poor lifestyle ,meaning bad diet high in trans fats poor exercise.............

Answer 6

Colateral arteries - my son was born with these as he didn't have a pulmonary artery. I think it is amazing that your body can compensate in this way!!
