The experts involved in the study evaluated 12 dietary supplements and found that eight had at least one ingredient linked to dangerous heart complications such as ventricular arrhythmia, stroke and sudden death.

While all products included a list of its components, none had a warning about the potential adverse cardiac effects, thus obscuring customers the dangers of these pills to lose weight.

“Consumers have a false sense of security when they use them,” said Dr. Mehdi Razavi, the Texas Heart Institute, who presented the findings at a meeting of the Heart Rhythm Society in San Francisco.
Many heart attack people assume that the FDA supports the safety and efficacy of supplements but supplements, including many weight loss products are not subject to the same security controls that the drugs by the Food and Drug United States (FDA).

Razavi not provide the names of the pills tested, but offered a list of hazardous ingredients found in such supplements.
The team even found a compound, a type of ephedra known as Ma Huang root, which is banned by the FDA since 2004. Potentially risky ingredients are the result of Ma Huang, a type of ephedra banned by the FDA since 2004, the bitter orange, also known as Synephrine HCl and Citrus aurantium, green tea, also known as Camellia sinensis and black wheat, buckwheat or Korean ginseng, among others.

Some of the chemicals found can cause problems by reducing the levels of potassium, which could alter the heart’s electrical system. Others, such as green tea, are harmless when consumed in normal amounts, but can amplify the effects of other ingredients.

So when you decide to take a product or thermogenic fat burner is best to check with your doctor to evaluate possible consequences of its use against the benefits you could achieve.

The study found that any kind of exercise was very useful in correcting vascular dysfunction in patients who had suffered a heart attack, no difference was found between resistance training, aerobics or in combination.

But the improvement in blood flow observed in the 209 survivors who participated in the study, was lost after four weeks of the cessation of exercise. This proves that this kind of patients should be kept in a constant training program to maintain vascular benefits.

Exercises for the heart of the test participants were randomly assigned to aerobic exercises, resistance exercises and a combination of aerobic and resistance training.

Those who did aerobic exercise had four sessions a week, which included a ten-minute warm-up, forty minutes of cycling, which increased the heart rate to 75 percent of the maximum and ten minutes of cooling.

Resistance exercises included four sessions a week to ten exercises with weights and rubber bands, which lasted from 45 to 60 seconds with rest intervals of 15 to 30 seconds.

According to Dr. Johnny Lee, an assistant clinical professor of medicine at Mount Sinai Medical Center in New York City, “If this applies to the sickest patients, that if you lose the benefit for shows that continue to exercise can only a positive effect if you are a normal subject without heart disease. ”

Reason enough to consider seriously and responsibly the start a fitness program that includes at least 2 to 3 sessions per week.

The results, according to eight clinical trials on more than 24,000 people, support the recommendations against the use of vitamins B to prevent heart disease.

The idea that the B vitamins, like folic acid, B-6 and B-12, help prevent cardiac complications from the fact that lower blood levels of an amino acid called homocysteine.

Homocysteine levels increase in people with atherosclerosis, which is the buildup of plaque in the arteries that cause heart attacks and strokes.

But researchers do not know whether high homocysteine levels promote the progression of atherosclerosis or are only an indicator of cardiac risk. No clinical trial showed that vitamin B supplements prevent heart attack and stroke.

To strengthen the evidence, the new review collected data from eight clinical trials on the effects of folic acid, vitamins B-6 and B-12 or combinations thereof.

The trials included 24,210 people with established cardiovascular disease (atherosclerosis or previous stroke or other cardiac complications) or their risk factors, such as diabetes, hypertension or high cholesterol.

The authors found that adding supplements to conventional medical therapy did not lower the risk of heart attack, stroke or death of participants in the seven years of monitoring.

The results appear in the Cochrane Library, a publication of the Cochrane Collaboration, which is an international organization that evaluates medical research.

The review provides “solid evidence” that these B vitamins do not prevent heart problems and stroke, told Reuters Health Dr. Arthur J. Marti-Carvajal, Iberoamerican Cochrane Network, in Valencia, Venezuela.

The recommendation for people who want to take care of your heart health is to drop the B vitamins and either: not smoking, exercising, controlling blood pressure, cholesterol and blood sugar regularly and eat a balanced diet and a rich in fruits and vegetables and low in fast food and other unhealthy products.
