Your doctor may suggest that you have an echocardiogram or heart ultrasound examination. The echocardiogram is very useful in the evaluation of the hearts structure and function along with an assessment of the major arteries all of which can be adversely affected by hypertension. Treatment The treatment of hypertension and blood pressure goals are dependent on how healthy you are.

Researchers test theories of beet juice benefits By Marjorie S. While beetroot juice rich in nitrates did not enhance muscle blood flow or vascular dilation during exercise, researchers found that it did "de-stiffen" blood vessels under resting conditions, potentially easing the workload of the heart.

Endurance athletes have been known to consume the crimson supplement based on the belief that it may improve blood and oxygen flow in their muscles during training and competition.

Some strength and power athletes consume it in hopes that it can improve their ability to withstand muscle fatigue during repeated bouts of high intensity exercise.

Now, some patients are asking their doctors if they should drink the juice to lower their high blood pressure. Those potential benefits are what prompted David Proctorprofessor of kinesiology and physiology at Penn State, to test the ability of the juice to enhance blood flow to exercising muscles.

Proctor, with other researchers, found that the widely held belief regarding improved muscle blood flow did not hold up to their test. They report their results in the journal Applied Physiology, Nutrition, and Metabolism.

Proctor and his colleagues gave subjects either a placebo drink containing beetroot juice minus the nitrate or a relatively high dose of nitrate-rich beetroot juice.

They found that the latter did not enhance the natural rise in blood flow to the forearm muscles during graded handgrip exercise.

Nitrates, found in highest concentrations in leafy green vegetables such as spinach and beetroot, are converted naturally in the body to nitric oxide, a molecule that relaxes and widens blood vessels and affects how efficiently cells use oxygen. A number of manufacturers have found ways to liquefy beetroots and concentrate the nitrate into beetroot juice "shots.

The investigators also observed a direct correlation between nitrite levels in the blood and the slowing of participants' arterial pulsation velocity, an indication that the supplement did indeed have a biological artery de-stiffening effect. Skulas-Ray, research associate in nutritional sciences.

Additional authors include David J. Kim-Shapiro, professors in the department of physics at Wake Forest University.Digestive problems related to reduced blood flow include: abdominal pain; diarrhea; bloody stools, constipation, and cramping.

Fatigue. Poor blood flow affects energy levels and can cause fatigue. This test also uses a blood pressure cuff and a probe similar to the pencil stethoscope to measure blood flow in the arteries of the legs, feet or arms.

Waveforms recorded with the Doppler ultrasound can help indicate the location and the severity of the disease. This is the path of blood flow through the body.

In conclusion the path of the blood flow through the body is a very complicated pathway and it is very difficult to remember. I have tried to explain it as detailed as I possibly could and I hope that you know more about the path of blood flow 3/5(3).

It is proposed that depression is the dysfunctional state arising from inadequate rates of blood flow to deliver the necessary oxygen and nutrient substrates to sustain normal tissue function in .

Like the abstract of a research paper, the project summary, should be no more than words and at the most a page long (font size 12, single spacing). Provided preferably on a separate page, it should summarize all the central elements of the protocol, for example the rationale, objectives.
