Hi,

I found this interesting but make of it what you will.

I tend to question the cause of my heart attack as I gave up smoking in 2001 having smoked cigars since the late 1960s. I NEVER add salt to food, we only use the bare minimum of salt in cooking, if atall.

I also do not eat junk foods – in fact there seems no reason for me to have had a heart attack – I wonder to what extent the removal of a cancerous kidney 12 years ago played a part, also did Sodium play any part in the blocking off of my right corunary artery from end to end?

Simple steps may identify patients that hold onto excess sodium

Augusta, Ga. – Getting a second urine sample and blood pressure measure as patients head out of the doctor’s office appears an efficient way to identify those whose health may be in jeopardy because their bodies hold onto too much sodium, researchers report.

“We want to prove that you can easily and efficiently identify these patients,” said Evan A. Mulloy, a second-year medical student at the Medical College of Georgia at Georgia Regents University. “We want this to become a part of our routine standard of care.”

Using the simple method, researchers looked at 19, 10-19 year-olds seeing a pediatric nephrologist. They found eight were sodium retainers and seven of these were already hypertensive. “Eight kids were holding onto sodium and the amounts ranged anywhere from a few milligrams to hundreds of milligrams over the course of a doctor’s visit,” Mulloy said.

The findings are featured as a poster presentation at the American Heart Association‘s High Blood Pressure Research 2013 Scientific Sessions Sept. 11-14 in New Orleans.

About 1 in 3 blacks and 1 in 5 whites retain too much sodium following stress, driving fluid retention and blood pressure levels up, said Dr. Gregory A. Harshfield, a hypertension researcher who directs the Georgia Prevention Center at GRU’s Institute of Public and Preventive Health.

Years ago, Harshfield identified this impaired ability in some blacks and wanted to take the next logical step: finding an easy, inexpensive way to identify these individuals. His studies, funded by the National Institutes of Health, have already shown sodium retainers respond well to angiotensin receptor blockers. These drugs, which reduce blood vessel constriction, are widely used to treat hypertension but, ironically, they often are considered ineffective in blacks, Harshfield said. Studies at MCG and elsewhere have shown angiotensin promotes sodium retention directly and it increases aldosterone, another hormone that enhances sodium retention.

For the new study, Mulloy recruited patients as they came into the pediatric nephology clinic at Children’s Hospital of Georgia where patients have their blood pressure taken and provide a urine sample as part of their routine visit. Those who agreed to participate had both steps repeated at the conclusion of their visit for comparison sake.

The idea was that the stress of going to the doctor would be sufficient to cull out the sodium retainers. Increased sodium retention is one way the body responds to stress but normally, as soon as the stress passes, the extra sodium gets excreted in the urine.

To be effective, they knew the method for identifying retainers had to fit easily into a regular doctor’s visit. Knowing patients are sodium retainers will go a long way in helping physicians identify optimal therapies, including prevention strategies, Mulloy said. They are now using the method in adults seeing a general internist.

“Salt sensitivity is a great concept but it’s never been implemented into the clinical arena. We think this is a measure of salt sensitivity,” Harshfield said. Nearly 31 percent of American adults are hypertensive and more than half do not have their high pressure under control, according to the Centers for Disease Control and Prevention.

In a related poster presentation at the AHA meeting, the MCG team also presents early evidence that potassium supplementation could help maintain a healthier sodium level following stress.

While analyzing another cohort of young healthy blacks, Harshfield and Office Associate Deborah L. Stewart noted that sodium retainers in the group still dumped potassium. Normally, potassium and sodium are dumped at the same time, Stewart said. They are writing a grant now to explore whether potassium supplementation is an inexpensive and safe method to improve sodium excretion.

Stewart, who has worked with Harshfield for a year, helping write grants, abstracts and analyze data, is completing her undergraduate degree in biology with plans to move into a role as research assistant. Mulloy has worked with Harshfield for three consecutive summers, beginning when he was an undergraduate at William & Mary.

Vitamin D cuts blood pressure and slashes risk of stroke and heart attack

MILLIONS of people could reduce their risk of high blood pressure by going out in the sunlight every day, says a report published today.

Published: Wed, June 12, 2013

Scientists have found a direct link between a deficiency in vitamin D – caused by lack of exposure to the sun – and hypertension, which also raises the likelihood of stroke and heart attacks.

The worldwide study found that people with high concentrations of the “sunshine vitamin” had reduced blood pressure.

Scientists say there is a “strong case for food fortification with vitamin D to ­prevent some kinds of cardiovascular disease”.

A spokesman for Vitabiotics, who developed Ultra Vitamin D, which contains the preferred D3 form found in the body said: “Vitamin D has been called the ‘Wonder Vitamin’ as it plays a truly remarkable role in the body and is essential for all round good health. Vitamin D has been found to influence all 36 organ tissues in the body.

“It is not only vital for strong bones, but is now known for its role in the immune system, hormone metabolism, brain function and mood, Cardio-vascular function and now blood pressure regulation. While scientific data is mounting on almost a daily basis about the enormous benefits of vitamin D, at the same time it is clear most of us are not getting enough vitamin D due to the lack of sunlight we are exposed to throughout the year.

“New research shows that optimum intake levels of vitamin D may be far higher than previously thought and this has led to widespread calls from leading doctors and scientists across Europe for the RDA for vitamin D to be increased.”

Researchers at University College London carried out a genetic examination of 35 studies involving 155,000 people from across Europe and North America.

Lead researcher Dr Vimal Karani said while observational links between a lack of vitamin D and increases in blood pressure had been made in the past, the connection was not clear.

“The whole picture was somewhat confused, and we decided to try to figure it out once and for all,” he said.

Vitamin D is mainly made in the skin as a reaction to sunlight but may also be obtained from oily fish, eggs and fortified breakfast cereal. It is known to be important for good health, growth and strong bones.

In the study, researchers used genetic variants known as single nucleotide polymorphisms, or SNPs, to reflect an individual’s vitamin D status in order to test for an association with hypertension.

The results, published at the annual conference of the European Society of Human Genetics in Paris, found a significant link.

For every 10 per cent increase in vitamin D concentrations, there was a 8.1 per cent decrease in the risk of developing hypertension.

Vitamin D has been called the Wonder Vitamin

A spokesman for Vitabiotics

Dr Karani, from the Institute of Child Health at UCL, said: “To put it in simple terms, by using this approach we can determine the cause and effect and be pretty sure that we’ve come to the right conclusion.

“Our study strongly suggests that some cases of cardiovascular disease could be prevented through vitamin D supplements or food fortification.”

He added: “We believe that we still have a lot to find out about the effect of vitamin D deficiency on health, and we now know that we have the tools to do so.”

Most foods naturally contain very little Vitamin D.

Some foods are already fortified with it, and the study called this to be extended.

The report was welcomed by health organisations in Britain where around 16 million people suffer from high blood pressure, most of them unaware of it.

Katharine Jenner, chief executive of Blood Pressure UK, said: “This study adds to the increasing body of research suggesting vitamin D is linked to high blood pressure, one of the biggest causes of death in the UK. Lowering your blood pressure will lower your risk of having a stroke or a heart attack.”

She added: “Find out your blood pressure numbers, and then you can take appropriate action.

“If we are to prevent more cardiovascular diseases we need to consider all the tools at our disposal, which may include vitamin D fortification, but also eating less salt, more fruit and vegetables and more exercise.”

Lack of vitamin D is common throughout the Western world. Mild deficiency causes tiredness and general aches and pains, but a more severe lack can cause rickets – where long bones are weakened and start to bend – in children and softening of the bones in adults.

Most at risk are pregnant and breastfeeding women, children under five, people aged 65 and over, and those not exposed to much sun.

Oil battles tumours 

A spoonful of olive oil a day and handful of nuts could hugely increase the chances of surviving prostate cancer, a study suggests.

Replacing 10 per cent of carbohydrate in a sufferer’s diet with vegetable fats lowered the risk of death by 29 per cent.

And eating an ounce of nuts a day lowered that risk by 18 per cent, according to the University of California study published online by the journal Jama Internal Medicine.

Researchers reported: “Our findings support following a heart-healthy diet.”
