Echo saging of the body of AMVL, normal blood flow, trivial MR. Restrictions? Can I live normal and do everything? Only symp skip beats waning/waxing

Echo saging of the body of AMVL, normal blood flow, trivial MR. Restrictions? Can I live normal and do everything? Only symp skip beats waning/waxing

MVP: Such mild prolapse of the mitral valve is common and should not impact your physical activities, although atrial irritability certainly may occur. You could have a treadmill exercise stress test to see if strenuous physical exertion precipitates significant cardiac rhythm disturbances. Passing such a test will give you peace of mind. I recommend echocardiography every year or two to monitor mvp ...Read more

What does increased cerebral blood flow and volume mean?

What does increased cerebral blood flow and volume mean?

Tumors need nutrient: When tumors grow in the brain, they make new blood vessels (angiogenesis). These vessels are not normal compared to the non-tumor vessels. As a result, more blood flows into the tumor, which allows for more tumor growth. Since there is more flow, at any given time there is more blood volume in the tumor. Occasionally, there may be so much flow that it can shunt, or divert, flow from normal brain. ...Read more

Does blood flow from the anterior communicating arteries to the anterior cerebral arteries?

Does blood flow from the anterior communicating arteries to the anterior cerebral arteries?

Not exactly: The flow to the anterior cerebral starts at the heart, goes up the ascending aorta, to carotid arteries which reach the Circle of Willis, and go to anterior cerebral, middle cerebral and posterior cerebral arteries. Anterior communicating can be viewed as a bridging collateral. ...Read more

What meds increase cerebral blood flow, aside from acetazolamide?

What meds increase cerebral blood flow, aside from acetazolamide?

Vasodilators: Depending on your underlying medical conditions vasodiltors would include calcium channel blockers, beta blocker and nitrates. Acetazolamide is a diuretic- no effect of vasodilation: consult your cardiologist. ...Read more

Is there anyway to see if cerebral blood flow is reduced when standing? Got dysautonomia and suspect cerebral vasoconstriction is too excessive

Is there anyway to see if cerebral blood flow is reduced when standing? Got dysautonomia and suspect cerebral vasoconstriction is too excessive

Dysautonomia: Dysautonomia syndrome causes different symptoms alleviated by avoidance of stimulants, ensuring hydration, using magnesium, vitamin D & omega fish oils (www. Cardiamin. Com, use code: CMC), low dose beta blockers e.g. propranolol 5 to 10mg 2 to 3 times daily and SSRIs e.g. citalopram 5 to 10mg daily. Read Dr. Ronald Hoffman’s MVP book (www. Amazon. Com) and visit www. Dysautonomiainternational. Com. ...Read more

Studies show caffeine reduces Cerebral BloodFlow 27-40%... does this mean caffeine is damaging brain cells? Why not? Reduced blood flow is NOT good!?!

Studies show caffeine reduces Cerebral BloodFlow 27-40%... does this mean caffeine is damaging brain cells? Why not? Reduced blood flow is NOT good!?!

If that were: The whole truth, caffeine would not be the most widely used psychoactive agent on Earth. Caffeine also enhances alertness, enhances mental focus and improves score for all comers in tests of performance and cognition. So, this is what happens when you take one isolated physiologic response and try to then conclude something more complex about cell function, especially the brain. Neurobiology=??? ...Read more

Do beta-blockers decrease cerebral blood flow? What meds increase cerebral blood flow through cerebral vasodilation?

Do beta-blockers decrease cerebral blood flow? What meds increase cerebral blood flow through cerebral vasodilation?

NO: Betablockers do not reduce cerebral blood flow. Medicines that dilate cerebral blood vessels, like nitrates, cause headache. The brain has a mechanism called "autoregulation" that keeps flow constant. ...Read more

What R the lasting effects of a years worth of reduced cerebral blood flow due to vasoconstriction? Does the lack of proper CBF result in cell death?

What R the lasting effects of a years worth of reduced cerebral blood flow due to vasoconstriction? Does the lack of proper CBF result in cell death?

The long term effect: Of "reduced" CBF due to TEMPORARY constriction of the vessels (as in migraine) are not really known but several studies have shown that even severe chronic migraine does not reduce flow sufficiently to damage brain cells!

Hope this helps!

What does it mean when there is increased cerebral blood volume and blood flow to a brain tumor?

What does it mean when there is increased cerebral blood volume and blood flow to a brain tumor?

Cancer and blood flo: Many cancers elaborate factors that enable the growth of new blood vessels. In this way they gain an advantage in growth. When seen clinically on radiologic tests, this is a marker of malignancy and agressiveness, especially in the brain where low grade tumors only do this to a mild degree. Some cancers are treated by agents that interrupt this process, hoping to "starve" them of nutrients. ...Read more

Is there any drug that selectively increases cerebral blood flow but does not effect systemic blood pressure or heart rate?

Is there any drug that selectively increases cerebral blood flow but does not effect systemic blood pressure or heart rate?

Unlikely: I am not aware of such a drug. I am not sure why you might want this. There is not a specific way to do this and many drugs are able to cross the blood brain barrier. See your doctor if you have any symptoms you cannot complain. ...Read more

Nifedipine vs Nicardipine for Cerebral Vasodilating and Cerebral Blood flow? The literature says Nicardipine but it's not prescribed often right?

Nifedipine vs Nicardipine for Cerebral Vasodilating and Cerebral Blood flow? The literature says Nicardipine but it's not prescribed often right?

Nicardipine: These two meds are from the same class. Both vasodilate arteries and arterioles, both drop blood pressure, both are designed to have little or minimal effect on myocardial muscle contraction and cardiac conduction systems. Mg vs mg, nicardipine is slightly more potent in these vasodilating actions. The formulations account for this difference, as hypotension is the chief risk and hazard. ...Read more

In regards to blood flow, what is stenosis?

In regards to blood flow, what is stenosis?

Stenosis: Stenosis is the narrowing of a blood vessel that alters normal perfusion. Examples of stenosis in the vascular system are renal artery stenosis or carotid artery stenosis.
The development of atherosclerotic plaques sometimes occludes so much of a blood vessel that stenosis occurs. ...Read more

Does hypercapnia help accelerate your blood flow?

Does hypercapnia help accelerate your blood flow?

Yes. In the brain.: Hypercapnea does increase blood flow in the brain by causing cerebral vessel vasodilation. This is part of a process in the brain termed cerebral autoregulation. It also can lead to peripheral vasodilation by direct effects on blood vessels. This may also lead to increased blood flow. However, this would not be a desirable effect for anything other than the body's normal response to changes in ph. ...Read more

No: Difficult to do with the liver's circulation, but if theoretically all blood flow stopped, it would die, then "rot" (/necrose) and degeneration/waste products would build up in the body, making it toxic and eventually causing heart function / rhythm problem and death.
