(Press-News.org) Vienna, Austria - 3 December 2014: The Mediterranean diet is linked to improved cardiovascular performance in patients with erectile dysfunction, according to research presented at EuroEcho-Imaging 2014 by Dr Athanasios Angelis from Greece. Patients with erectile dysfunction who had poor adherence to the Mediterranean diet had more vascular and cardiac damage.
EuroEcho-Imaging is the annual meeting of the European Association of Cardiovascular Imaging (EACVI), a branch of the European Society of Cardiology (ESC), and is held 3-6 December in Vienna, Austria.
Dr Angelis said: "Erectile dysfunction is not a symptom of ageing, it is a bad sign from the body that something is wrong with the vasculature. In 80% of cases erectile dysfunction is caused by vascular problems and is a warning that patients are at increased risk of a heart attack or stroke."
He added: "The Mediterranean diet is associated with lower cardiovascular events and could be a way to help erectile dysfunction patients lower their risk. We wanted to investigate whether patients with erectile dysfunction who follow this diet have less vascular and cardiac damage."
The study included 75 men with erectile dysfunction, aged 56 years on average, who attended the Department of Cardiology at Hippokration Hospital in Athens, Greece. Adherence to the Mediterranean diet was assessed with the Med-Diet Score1 which ranks patients as high (30-55), intermediate (21-29) or low (0-20) according to consumption of cereals, fruit, vegetables, meat, fish, dairy products, wine and olive oil.
Vascular function was assessed by measuring two aspects of atherosclerosis, namely atheromatosis and arteriosclerosis. Atheromatosis refers to the development of atheroma (plaque), a fatty deposit in the intima (inner lining) of the artery, and was measured by the intima-media thickness (IMT) of the common carotid artery. Arteriosclerosis refers to the stiffening of the arteries and was evaluated with carotid-femoral pulse wave velocity (PWV). Heart involvement was based on diastolic function and left ventricular mass.
The researchers found that a lower Med-Diet Score correlated with significantly worse vascular and heart function. These patients had greater IMT and aortic stiffness as well as higher left ventricular mass and more profound diastolic dysfunction.
Dr Angelis said: "Patients with erectile dysfunction who had unhealthy diets had more vascular and cardiac damage than those who followed the Mediterranean diet. Previous studies have shown that patients with erectile dysfunction have vascular damage but we found that the heart is also damaged. This may help to further explain why these patients are more prone to cardiovascular events. The formation of atheroma, the stiffening of the arteries, and the poor functioning of the heart can eventually lead to a cardiac event."
He added: "Our findings suggest that adopting the Mediterranean diet can improve the cardiovascular risk profile of patients with erectile dysfunction and may reduce their chances of having a heart attack or stroke. This needs to be tested in a larger study."
The Mediterranean diet is characterised by daily consumption of fruit, vegetables, unrefined cereals and pasta, olive oil and nuts. Dairy products are eaten in modest amounts, in the form of yogurt and cheese. Consumption of meat is low, with red meat once a week and poultry once a week considered a healthy level. A modest amount of wine can be consumed, and refined sugar should be avoided in favour of natural desserts like fruit.
Dr Angelis said: "Really simple changes in our diet may help a lot, for example using olive oil which contains monounsaturated fat. If someone doesn't have the money to buy some of the foods they can substitute them with others, for example nuts are a good source of monounsaturated fat. Sometimes it's difficult to adopt something if you consider that it's part of a prescription, but the Mediterranean diet is not a prescription, it's a lifestyle. It's about having an awareness of what foods are healthy or unhealthy."
He concluded: "Patients who have erectile dysfunction and don't adhere to the Mediterranean diet have vascular and cardiac damage and are at increased risk of heart attack and stroke. Our findings suggest that adopting a healthy diet can reduce that risk. We also advise patients to stop smoking, exercise and ensure that they have healthy levels of blood pressure and lipids."

CHICAGO - Researchers reported today on a procedure that can preserve fertility and potentially save the lives of women with a serious pregnancy complication called placenta accreta. Results of the new study presented at the annual meeting of the Radiological Society of North America (RSNA) showed that placement of balloons in the main artery of the mother's pelvis prior to a Caesarean section protects against hemorrhage and is safe for both mother and baby.
Placenta accreta, a condition in which the placenta abnormally implants in the uterus, can lead to additional complications, ...
CHICAGO - Researchers at Mayo Clinic found that some children are receiving chest X-rays that may be unnecessary and offer no clinical benefit to the patient, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"Chest X-rays can be a valuable exam when ordered for the correct indications," said Ann Packard, M.D., radiologist at the Mayo Clinic in Rochester, Minn. "However, there are several indications where pediatric chest X-rays offer no benefit and likely should not be performed to decrease radiation dose ...
CHICAGO - A popular surgery to repair meniscal tears may increase the risk of osteoarthritis and cartilage loss in some patients, according to research presented today at the annual meeting of the Radiological Society of North America (RSNA). The findings show that the decision for surgery requires careful consideration in order to avoid accelerated disease onset, researchers said.
The new study focused on the meniscus, a wedge-shaped piece of cartilage in the knee that acts as a shock absorber between the femur, or thighbone, and tibia, or shinbone. The two menisci ...
New research from researchers at Queen Mary University of London (QMUL) looking at how goats express subtle positive emotions could lead to greater understanding of animal welfare. While there has been a great deal of research into negative emotions and stress in animals it is often hard for those who work with animals to know when they are in more subtle positive states.
Dr Alan McElligott and Dr Elodie Briefer, working from QMUL with goats at Buttercups Sanctuary for Goats, carried out the first research, published today (Wednesday) in the journal Animal Behaviour, ...
Pregnant women in Bangladesh with low levels of the most common form of vitamin E are nearly twice as likely to have a miscarriage than those with adequate levels of the vitamin in their blood, according to new research led by the Johns Hopkins Bloomberg School of Public Health.
The findings, published online last week in the American Journal of Clinical Nutrition, suggest that improving the diet of women in impoverished nations or encouraging intake of vitamin E through prenatal supplements could have a direct impact on fertility, though more research is needed.

A new study from the UT Dallas Center for Vital Longevity shows that the brain activity prior to seeing an item is related to how well it is later remembered.
In the study published online in NeuroImage, the researchers showed that receiving information about a pair of items before seeing them may affect how well they are remembered.
Moreover, the researchers also found that the activity in different areas of the brain was unexpectedly related to how the information was remembered.
"If you're interested in memory, you want to know the factors that are associated ...
The deadly fungal disease known as white-nose syndrome has spread to bat colonies throughout eastern North America over the past seven years, causing bat populations to crash, with several species now at risk of extinction. The devastating impact of this disease is due in part to the seasonal dynamics of infection and transmission, according to a new study led by scientists at the University of California, Santa Cruz, and published December 3 in the Proceedings of the Royal Society B.
The researchers were surprised to discover that during the winter, when the bats are ...
It takes just 10 years for a single emission of carbon dioxide (CO2) to have its maximum warming effects on the Earth.
This is according to researchers at the Carnegie Institute for Science who have dispelled a common misconception that the main warming effects from a CO2 emission will not be felt for several decades.
The results, which have been published today, 3 December, in IOP Publishing's journal Environmental Research Letters, also confirm that warming can persist for more than a century and suggest that the benefits from emission reductions will be felt by those ...
Washington, D.C.--The climate warming caused by a single carbon emission takes only about 10 years to reach its maximum effect. This is important because it refutes the common misconception that today's emissions won't be felt for decades and that they are a problem for future generations.
For the first time, a study conducted by Carnegie's Katharine Ricke and Ken Caldeira has evaluated how long it takes to feel the maximum warming effect caused by a single carbon emission. Their work is published in Environmental Research Letters.
"A lot of climate scientists have ...
An adaptable strategy that intelligently and flexibly combines positive and negative incentives turns out to be the optimal approach for institutions to encourage the highest level of cooperation at the lowest cost, according to a new study published in the Royal Society journal Interface.
"This study applies to many real-life situations, such as teachers incentivizing student efforts or governments seeking compliance with environmental regulations," says IIASA Evolution and Ecology Program Director Ulf Dieckmann, who led the study in collaboration with IIASA researchers ...
