Bacterial endocarditis occurs when bacteria (germs) enter the bloodstream and lodge inside the heart, where they multiply and cause infection. A normal heart has a smooth lining, making it difficult for bacteria to stick to it.
Full Answer
A systemic infection has similar symptoms, but they occur throughout the whole body, resulting in a fever. Though bacterial infections don’t commonly affect the heart, it does happen. The resulting cardiac inflammation is called myocarditis, which can be difficult to detect but presents symptoms such as:
[Gut-heart axis : How gut bacteria influence cardiovascular diseases] The view of humans as holobionts consisting of eukaryotic host cells and associated prokaryotic organisms, has opened up a new perspective on cardiovascular pathophysiology. In particular, intestinal bacteria influence the cell and organ functions of the host.
Gut bacteria may play role in heart attack recovery. The tiny microbes located inside the intestines could play a critical role in heart attack recovery, according to a new study that found gut bacteria helpful in repairing the damage after a heart attack.
For example, certain illnesses, like bowel diseases, can break down the mucus membranes in the intestines. This breakdown creates openings through which intestinal bacteria can enter the bloodstream and even reach the heart.
Bacteria, fungi or other germs from another part of your body, such as your mouth, spread through your bloodstream and attach to damaged areas in your heart. If it's not treated quickly, endocarditis can damage or destroy your heart valves. Treatments for endocarditis include medications and, sometimes, surgery.
Endocarditis is a rare and potentially fatal infection of the inner lining of the heart (the endocardium). It's most commonly caused by bacteria entering the blood and travelling to the heart.
Bacterial endocarditis is an infection of the heart's inner lining or heart valves. It's a serious condition that needs to be treated right away. Endocarditis can cause serious complications. It can also lead to death.
Heart infections occur when an irritant such as bacteria, a virus, a parasite, or a chemical reaches your heart muscle. An infection can cause inflammation or damage to your heart's inner lining, valves, outer membrane, or the heart muscle itself.
You can often control a heart infection with medications and sometimes with surgery. If you have a cut or skin infection that doesn't heal, loss of consciousness or shortness of breath, seek help immediately.
Endocarditis can happen more than once. You'll need to do your part to make sure you recover from endocarditis and stay well. You may need a blood test every day or two to check for bacteria until it's gone. You may need to have another echocardiogram now and then to see how well your heart is functioning.
Conclusions: Long term survival following infective endocarditis is 50% after 10 years and is predicted by early surgical treatment, age < 55 years, lack of congestive heart failure, and the initial presence of more symptoms of endocarditis.
What are the symptoms of infective endocarditis? The symptoms of acute IE usually begin with fever (102°–104°), chills, fast heart rate, fatigue, night sweats, aching joints and muscles, persistent cough, or swelling in the feet, legs or abdomen.
Acute bacterial endocarditis is usually caused by staphylococcus aureus bacteria and occasionally by the bacterial strains brucella and listeria. This form of infective endocarditis, compared to other forms, is more likely to affect normal heart valves.
There are four main groups of people who are at risk for infective endocarditis. People with underlying heart problems such as congenital heart disease, valvular heart disease, hypertrophic cardiomyopathy, rheumatic heart disease, or previous bouts of endocarditis.
Global survival was 75% at 6 months, and 57% at 5 years. The only non-significant factor was IE location. The annual instantaneous risk of death was 0.55 at 6 months, 0.18 at 1 year, then 0.03. After one year, the only prognostic factor was age.
Treatment with aqueous penicillin or ceftriaxone is effective for most infections caused by streptococci. A combination of penicillin or ampicillin with gentamicin is appropriate for endocarditis caused by enterococci that are not highly resistant to penicillin.
Another less serious method of bacteria entering the bloodstream is through our mouths. When we brush our teeth or chew gum, we can cause micro-cuts that allow bacteria to enter the blood. Most microbes will be dealt with by the immune system. However, in people with weakened immune systems, or who already have an infection, certain microbes can enter the cardiovascular system and infect the heart leading to BE . researchers that performed a study on oral-originating endocarditis (OOE) have shown that the primary cause of OOE are bad hygiene patterns and whether or not the person has had a dental procedure in the last 3 months . This finding suggests that keeping a proper oral hygiene prevents someone from contracting endocarditis. However, as the saying goes, too much of a good thing can also be bad because if bacteria exists on a toothbrush or dental floss than it can enter the bloodstream via microtears in the gums.
The common causes of bacterial endocarditis include streptococcus, staphylococcus and enterococcus . All of these pathogens are commonly found around medical hospitals and can be common with post-surgical infections. Furthermore, all of these diseases are treated via antibiotics. However, certain strains are rapidly becoming resistant due to our misuse of antibiotic drugs. Two of these virulent strains E. faecalis and E. faecium help to illustrate the specific phenotypes required for thriving within the heart chambers. Specifically, how they adhere inside the heart in the first place. The main challenge that these diseases have in infecting human hosts is being able to adhere to the heart wall and proliferate to cause disease. Both E. faecalis and E. faecium are prime examples of this evolutionary advantage because they specifically take advantage of this unique environment in order to grow as a colony. Furthermore, researchers have shown that these strains of bacteria have mechanisms for antibiotic resistance to all clinically relevant antibiotics . Moreover, the researchers state that the resistance was most likely acquired through mutation or horizontal gene transfer by other resistant diseases in hospitals.
During open heart surgery, this is a big problem because doctors have to cool the heart down in order to slow its beating and perform the operation. Blood flow greatly decreases during this time and it gives bacteria a chance to enter the body through the capillaries. When the surgery is done and over with, blood flow is restored and the newly introduced pathogens are free floating throughout the body.
sepsis, which is a severe and potentially life-threatening infection that can spread throughout your body. pericardial effusion, or fluid buildup in your pericardium. pleural effusion, or fluid buildup in the area around your lungs. pneumonia.
as a result of trauma. People with a weak immune system are at an increased risk of developing bacterial pericarditis because their bodies are less able to fight infection.
Some people develop a condition known as chronic pericarditis, in which infection lasts for six months or more, or frequently recurs. Doctors only remove the pericardium if other treatments can’t stop the infection from occurring again.
The pericardium is a thin membrane that surrounds and protects your heart. This membrane helps prevent infection and also keeps your heart from expanding too much. Diseases and health problems can cause an inflammation of this membrane, a condition called pericarditis. The causes of pericarditis include: viruses. bacteria.
The most common symptom is sharp, stabbing chest pain, also known as pleuritis. This pain often moves or radiates to other parts of the body, including the left shoulder and neck. Other symptoms that may occur with bacterial ...
Other symptoms that may occur with bacterial pericarditis include: pain when you breathe. shortness of breath when lying down. a fever. a dry cough. fatigue. a general feeling of sickness, or malaise. sweating. splinting of the ribs, by bending over and holding your chest, while breathing.
If you have bacterial pericarditis, they’ll be able to detect pericardial rub, which is a sound that occurs when the layers of the infected pericardium rub together. Your doctor may also check to see if you have: sepsis, which is a severe and potentially life-threatening infection that can spread throughout your body.

The resulting inflammation can cause debilitating pain and may damage different parts of the heart. People with certain heart valve problems should take antibiotics before dental procedures to lower their risk of endocarditis. Image: Monkey Business Images/Thinkstock.
They found that by giving the mice a specific strain of bacteria called Akkermansia muciniphila, they could prevent inflammation — the chronic, persistent immune response that contributes to the buildup of fatty plaque in arteries.
Collectively known as the gut microbiota, these microbes assist with digestion, but also make certain vitamins, break down toxins, and train your immune system.
They discovered that when gut microbes feed on a chemical called choline (found in eggs, red meat, and dairy products), they produce a compound called TMA. In the liver, TMA is converted to TMAO, which causes hardening of the arteries (atherosclerosis) in mice and is linked to a higher risk of heart disease in humans.
At least 70% of our immune health depends on our gut. You may have a bigger colony of bad bacteria compared to the good one. One way is to turn it around, have a lot more good bacteria than bad ones.
The mice that got DMB in their water had healthier, clearer arteries than those that didn’t. Earlier this year, Chinese researchers described a different but related approach to preventing blood vessel injury in atherosclerosis-prone mice.
Loscalzo. There’s also some evidence that the gut microbiota may influence the levels of cholesterol and other fats in the bloodstream, as well as blood pressure.
The tiny microbes located inside the intestines could play a critical role in heart attack recovery, according to a new study that found gut bacteria helpful in repairing the damage after a heart attack.
They examined a group of lab mice that were treated with antibiotics to kill off their intestinal microbes seven days before they were given heart attacks. Some of the mice had a small mixture of gut bacteria restored to their system before the heart attack, while others in the group received a probiotic supplement after the attack.
Trillions of generally harmless and even helpful microbes live in the intestinal tract . Some of these gut bacteria have been shown to help educate and mature portions of the body's immune system, as well as regenerate tissues after injury.
While the study showed that gut bacteria and some products made by them played a beneficial role to repairing heart attack damage in mice, humans have an entirely different set of bacteria, he said. "Not all gut microbes do things that are beneficial.
Most of the mice that only received antibiotics died. However, the rodents that were given bacteria before their heart attack fared much better, and the mice that received probiotics even showed signs of better repair and better heart function.
More importantly, the findings caution against the overuse of antibiotics, said Dr. Patrick C.H. Hsieh, the study's lead author and a research fellow and professor at Academia Sinica and National Taiwan University and Hospital in Taipei, Taiwan.
There can be products that are made by gut microbes that actually cause harm," Hazen said, adding that some have even been linked to the progression of heart disease or conditions that affect heart health such as obesity and diabetes. "What this study does is show a role for gut microbes in the repair mechanisms after a heart attack.
You can be exposed to bacteria from other people, through the environment, or from eating contaminated food or drinking contaminated water.
Diagnosis. Treatment. Bacterial infections are common, and their effects vary. There are a number of different bacteria that can cause illness, and you can become exposed to them in a variety of ways. Bacteria are small organisms that can invade the body, causing illness. These infections usually trigger a protective immune response.
Bacterial infections can range from minor illnesses such as strep throat and ear infections to more life-threatening conditions like meningitis and encephalitis.
You can experience generalized symptoms, such as fevers, chills, and fatigue as a result of a bacterial infection anywhere in the body.
Salmonella is caused by a non-typhoidal salmonellae bacteria found in the intestinal tracts of humans and other animals, and the most recognized method of infection is through undercooked poultry. Escherichia coli (E. coli) causes gastrointestinal (GI) distress.
Methicillin-resistant Staphylococcus aureus (MRSA) is an antibiotic-resistant bacteria that can be deadly , particularly in people who have compromised immune systems. Clostridium difficile (C. diff) is a bacteria normally found in the intestine.
Similarly, sexually transmitted infections can be identified with a fluid sample from the affected area. A urine sample can identify bacterial infections of the bladder and kidneys. In some situations, a fecal sample may be helpful in identifying a bacterial cause of persistent gastrointestinal (GI) upset.
