Red meat is considered bad news when it comes to heart health, although studies aren’t consistent about how much can hurt and whether it always does. As the researchers describe today in Nature Medicine, mice fed a diet supplemented with L-carnitine for 15 weeks had much higher levels of TMAO than control animals. And the intestines of the mice getting extra L-carnitine also adapted, becoming enriched for various classes of bacteria that could more readily convert L-carnitine to TMAO. Infective endocarditis (also called bacterial endocarditis) is an infection of the inner lining (endocardium) of the heart's chambers or valves. Endocarditis rarely occurs in people with normal hearts. You're more likely to get infective endocarditis if you have abnormal or damaged heart valves or certain birth defects of the heart. Until recently, everyone at increased risk of getting infective endocarditis was told they should take antibiotics before having certain kinds of dental work or surgery. If you have had heart problems from birth (congenital) or as a result of rheumatic fever, you're at greater risk of getting endocarditis.
Also, people who inject illegal drugs into their veins often develop infections on normal valves because of reusing or sharing needles.
Infective endocarditis is an infection of the inner lining of the heart's chambers or valves. Your doctor will take a medical history and listen to your chest for the sound of a heart murmur, which could signal a heart valve problem. Computed tomography (CT or CAT scans) and other tests also may show clumps of abnormal tissue on the heart valves. In past years, the American Heart Association has recommended that patients at increased risk for endocarditis take a preventative dose of antibiotics before certain dental, GI and GU procedures. Now, fewer people than in the past need to take antibiotics before a dental procedure that manipulates the gums or a part of a tooth. Antibiotics are no longer routinely recommended EXCEPT for patients with the highest risk of a bad outcome resulting from endocarditis. The American Heart Association no longer recommends giving antibiotics to prevent endocarditis in people who undergo a GI or GU tract procedure. If you have a heart condition, ask your doctor if you are in one of the categories of highest risk for a bad outcome from endocarditis.
Take antibiotic medicine prescribed by your doctor before you have certain dental work or before some specific procedures that involve the respiratory tract.
HEART DISEASE - Numerous studies have shown a relationship between oral bacteria and the buildup of fatty plaques in arteries (atherosclerosis). Atherosclerosis (ath"er-o-skleh-RO'sis) comes from the Greek words athero (meaning gruel or paste) and sclerosis (hardness).


Researchers are finding clues to why people with a chronic gum disease seem to have an increased risk of heart disease and stroke.
First, the researchers stress that this possible link between certain bacteria in the mouth and heart disease is not yet fully studied.
Gum Disease and Tooth Decay - 3 Ways to Improve Dental Health and Reduce Your Risk of Heart Disease By Dan Martin. The latest findings on oral and heart health highlight a direct association between certain bacteria in the mouth and heart disease. A complicated dance between the microbes and a component of red meat could help explain how the food might cause atherosclerosis.
Two years ago, he and his colleagues published a paper in Nature identifying a compound in the blood called trimethylamine N-oxide (TMAO). The finding is the latest in a series of studies that have shown that the population of bacteria in our guts—collectively known as the gut microbiome—can influence everything from weight loss to brain chemistry. Animals getting extra L-carnitine had about double the burden of atherosclerosis in their arteries compared with mice eating a normal diet.
This hinted that people who eat lots of red meat might be especially efficient at converting L-carnitine to TMAO and that consuming the food in moderation could be less harmful because the conversion might be more sluggish. Work by Hazen’s group hints that TMAO seems to make it easier for immune cells in the arteries to accumulate cholesterol.
It can lead to uncontrollable infection (sepsis) resulting in cardiac arrest. Infective endocarditis can permanently damage your heart valves, and may cause heart failure, stroke and abnormal heart rhythms (arrhythmias).
Now, however, only people at the highest risk for a bad outcome resulting from endocarditis are recommended to receive antibiotics before certain dental procedures.
If your heart is damaged — for example, if you have a leaky valve — bacteria are more likely to settle in the damaged spot.
But bacteria in your bloodstream can stick to the inner lining of your heart or build up on the heart valves and cause infections.
Recently, however, they revised their guidelines and concluded that there is no solid evidence linking dental, GI or GU tract procedures with the development of endocarditis.
If you are having a surgical procedure that involves infected skin, skin structure, or musculoskeletal tissue, you may also be advised to take an antibiotic. Brush at least twice a day, floss once a day and see your dentist for an examination and cleanings regularly. It's the name of the process in which deposits of fatty substances, cholesterol, cellular waste products, calcium and other substances build up in the inner lining of an artery. Dave Carpenter, 50, said many diseases, such as diabetes and heart disease, cause changes in the mouth. The work also has implications for certain energy drinks and energy supplements, which contain the same nutrient that these bacteria like chasing after.


Various studies have considered saturated fat or sodium but the results are inconsistent and sometimes depend on whether meat has been processed or not.
It seemed to correlate with future heart disease risk and cause heart disease when fed to mice. Twenty-three vegans and vegetarians given L-carnitine supplements were, Hazen’s group found, less able to synthesize TMAO than those who regularly ate red meat.

Often doctors start giving you the medicine in the hospital through an IV (intravenous) line.
They also concluded that endocarditis is much more likely to result from exposure to random germs associated with daily activities like chewing food than from a dental, GI or GU tract procedure.
Plaques that rupture cause blood clots to form that can block blood flow or break off and travel to another part of the body. This showed that something was converting L-carnitine to TMAO, but the researchers couldn’t say yet that the culprits were bacteria. For example, fish, which is thought to lower cardiovascular risk, also contains much lower levels of L-carnitine, as do chicken and milk, notes Dariush Mozaffarian, an epidemiologist at the Harvard School of Public Health in Boston who has studied meat and heart disease, in an e-mail. Many people can complete the antibiotic treatment at home, which may take up to 6 weeks or even longer. If either happens and blocks a blood vessel that feeds the heart, it causes a heart attack. L-carnitine is a popular additive to energy drinks and supplements that claim to boost energy levels. Hazen wondered if the bugs might also convert L-carnitine to TMAO, which, in turn, could put the heart at risk. To pin this down, they gave five of their volunteers broad-spectrum antibiotics for a week to suppress gut microbes and then repeated the experiment.
After the infection is gone, you may need surgery to repair or replace a valve the infection has damaged. This time, there was virtually no TMAO in the blood or urine after the volunteers ate steak, suggesting the conversion couldn’t happen without bacteria present. And if blood supply to the arms or legs is reduced, it can cause difficulty walking and eventually lead to gangrene.
