Vasodilation refers to the widening of blood vessels. It results from relaxation of smooth muscle cells within the vessel walls, particularly in the large veins, large arteries, and smaller arterioles. The process is essentially the opposite of vasoconstriction, which is the ...Read more
Metastases are: A mystery, but there are clear events necessary. Establishing a blood supply that delivers nutrients and carts away metabolites seem necessary (some tumors grow nicely in anaerobis, acidic, toxic environs). The colony secretes a local paracrine stimulus to develop a blood supply. Vegf also seems critical in development embronically of the cardiovascular system. ...Read moreSee 1 more doctor answer

Pregabalin calcium channel drug. Will it affect my blood vessels.. Vaso constrict dilate.. Blood pressure heart rate?
Difference in vessel: This is a protective mechanism. The vessels in the brain dont have as much ability to contract compared to peripheral blood vessels. The brain is the main server of the body and has to be protected to keep the rest of the body functioning. The peripheral vessels constricting causes shunting of the blood towards the path of least resistance. ...Read more
Yes: Vascular endothelial growth factor (vegf) is a substance that cells produce which helps them recruit the growth of new blood vessels. Blood vessels are essential in bring normal cells and cancer cells the oxygen and nutrients they need to keep growing. The growth of some types of cancer can be slowed or controlled by blocking vegf. ...Read more
Nitric oxide supplements -- what is their role in reducing hypertension and cardiovascular disease?
Nitric oxide: Nitric oxide was thought to be an endothelial relaxation factor which is released from endothelial cells to smooth muscle cells and relaxes them to lower resistance and lower blood pressure. There has been no randomized controlled study to test the benefit of supplements in reducing hypertension or cardiovascular disease. ...Read more
Starling mechanism: You mean how does venous pressure regulate cardiac output.similar to the Starling mechanism-by increasing pre load. Up to a certain point cardiac output is directionally proportional to venous pressure assuming that everything else is the same such as the after load or cardiac contractility ...Read more
Dysautonomia body over vasoconstricts in the brain causing reflex bradycardia and light headedness, midodrine makes worse, florinef (fludrocortisone) lowers k. Help!
Comments: You describe a somewhat peculiar constellation of vascular effects, and the medications selected may not be the most appropriate, if your blood pressure does not drop when standing. You need clarification, and would encourage a neurological and cardiological second opinions. Have you had a tilt table test? ...Read more
You can slow it down: We start to develop atherosclerosis in our 30's and generally it progresses as we age. People who have a family history of heart disease or stroke are more susceptible. You can slow down the progression of this disease by watching your cholesterol, keeping your blood pressure in check, attaining your ideal body weight and quitting smoking. Regular exercise, stress management and good eating helps! ...Read moreSee 1 more doctor answer
