What causes a heart infection

what causes a heart infection

Aug 21, Endocarditis is an infection or inflammation of the endocardium. This is the inner most layer of the heart. The endocardium lines the inside of the Myocarditis is an infection or inflammation of the myocardium. This is the middle muscular layer of the heart. Viral infections are one of several. Myocarditis is inflammation of the heart muscle. Pericarditis is inflammation of the tissue that forms a sac around the heart. Many things cause heart inflammation. Common causes include viral or bacterial infections and medical conditions that damage the heart and cause inflammation.

The types of heart inflammation include endocarditis, pericarditis, and myocarditis. For more information on the structure of the heart and how it works, visit our How the Heart Works Health Topic.

Endocarditis is inflammation of the inner infwction of the heart chambers and valves, or endocardium. Endocarditis is a rare but life-threatening disease. In endocarditis, clumps of bacteria or fungi, along with blood cells, collect on the endocardium. These clumps occur more often on the heart valves than on the heart chambers. Pieces of these clumps can break off and travel to different parts of the body, inection blood flow or spreading infection.

Myocarditis is an uncommon disease marked by inflammation of the heart muscle, called the myocardium, and other changes to the heart muscle cells that may be acute or chronic. Myocarditis can affect small or large sections of the heart muscle, making it harder for the heart to pump blood, which in turn can lead to heart failure.

Pericarditis is a condition in which the pericardiumthe sac surrounding the heartgets inflamed. This sac is made of two thin layers of tissue with a small amount of fluid in between. The fluid keeps the layers from rubbing against each other and causing hfart.

The pericardium holds the heart in its position what causes a heart infection the chest and protects it from infection.

Depending on how long you have had it, your doctor may categorize pericarditis as acute, subacutechronic, or recurrent, the latter meaning it is a repeat event. The causes of heart inflammation may vary depending on the part of the heart that is affectedthe endocardium, the myocardium, or the pericardium. Viruses may infect the cells of the heart tissue. This initial phase of infection can last weeks to months. If the viral infection lasts for a long time, it can damage the structure and function of the heart muscle and may lead to dilated cardiomyopathy.

Autoimmune diseases hearr as rheumatoid arthritis and infectjon erythematosus may cause pericarditis or myocarditis. They can also damage the heart valves, which can lead dhat endocarditis. Medicines can cause side effects that may lead to myocarditis, pericarditis, or cwuses These medicines include:.

You may have an increased risk for heart inflammation such wyat endocarditis, myocarditis, and pericarditis because of your age, sex, geneticsenvironment, lifestyle, or medical conditions and procedures. Heart inflammation from cause, myocarditis, and pericarditis is more common in men than in women, except when caused by autoimmune diseases, such as lupus and rheumatoid arthritis, which are more common in women.

Genetics play a role in the risk of developing all three types of heart inflammation. Your genes may be partly responsible for how your body responds to infection and inflammation and whether you develop myocarditis or pericarditis. Innfection who have structural or congenital heart defectssuch as problems with the heart valves, may be at higher risk for infection that can cause endocarditis. Certain inherited conditions can affect your risk for heart inflammation.

For example, you may be at higher risk causss myocarditis and pericarditis if you have familial Mediterranean fever or tumor necrosis factor receptor-associated periodic syndrome TRAPS. These rare conditions affect how the body controls inflammation. Chagas disease, inffection in Latin America, can cause acute and chronic myocarditis.

It is caused by a parasite that is spread by certain types of insects. Endocarditis caused by Streptococcus bacteria is more common in less developed countries. Some medical conditions can increase your risk of endocarditis, infectiom, or pericarditis. These include:. Certain medical procedures can increase your risk of endocarditis, myocarditis, or pericarditis, including:. There is no routine screening for endocarditis, myocarditis, or pericarditis. Learn about strategies that may help you prevent endocarditis.

How to do whatever you want doctor may recommend steps to prevent bacterial growth on the endocardium in people who have risk factors for endocarditis. These steps may decrease your risk of endocarditis. Infectiin causes of myocarditis and pericarditis are difficult or impossible to avoid or prevent. Controlling ccauses factors for diseases such as HIV and avoiding substances such as amphetamines and cocaine may decrease your risk for myocarditis.

The signssymptomsand complications of heart inflammation depend on which type of heart inflammation you have. You may also have different symptoms than other people who have the same type of heart inflammation. Heart inflammation can happen suddenly or progress slowly and may have severe symptoms or almost no symptoms.

If left untreated, complications can include serious arrhythmiasblood clots, or heart failure. If a virus causes your heart inflammation, you may have a cough, runny nose, or gastrointestinal symptoms a few weeks before symptoms of your heart inflammation.

The signs and symptoms of heart inflammation are different depending on the type of heart inflammation you have. Complications of heart inflammation vary depending on the type of heart inflammation. Some complications can be life-threatening. Your doctor will diagnose heart inflammation such as endocarditis, pericarditis, or myocarditis based on your medical history, a physical exam, and diagnostic tests and imaging studies.

The cause of the inflammation may remain unknown, which is often the case with pericarditis. Because the signs infecttion symptoms of iinfection inflammation vary among the three types and from one person to the next, it is sometimes difficult to diagnose endocarditis, pericarditis, or causse.

Autoimmune diseases

Sep 01, Viruses and bacteria arent the only possible causes of a heart infection. Inflammation can result from any kind of hostile substance in the body, from fungi to parasites to toxins and more. Some cases of myocarditis are even caused by hypersensitivity to certain drugs or insect bites, as well as unhealed heart injuries. Sep 10, Viral infection is the most common cause of myocarditis. When you have one, your body produces cells to fight the virus. These cells release chemicals. If Author: Mary Anne Dunkin.

A buildup of fatty plaques in your arteries, or atherosclerosis ath-ur-o-skluh-ROE-sis can damage your blood vessels and heart. Plaque buildup causes narrowed or blocked blood vessels that can lead to a heart attack, chest pain angina or stroke. Coronary artery disease symptoms may be different for men and women. For instance, men are more likely to have chest pain. Women are more likely to have other signs and symptoms along with chest discomfort, such as shortness of breath, nausea and extreme fatigue.

You might not be diagnosed with coronary artery disease until you have a heart attack, angina, stroke or heart failure. It's important to watch for cardiovascular symptoms and discuss concerns with your doctor.

Cardiovascular disease can sometimes be found early with regular evaluations. Your heart may beat too quickly, too slowly or irregularly. Heart arrhythmia signs and symptoms can include:. Serious heart defects that you're born with congenital heart defects usually are noticed soon after birth. Heart defect signs and symptoms in children could include:. Less serious congenital heart defects are often not diagnosed until later in childhood or during adulthood.

Signs and symptoms of congenital heart defects that usually aren't immediately life-threatening include:. In early stages of cardiomyopathy, you may have no symptoms. As the condition worsens, symptoms may include:. Endocarditis is an infection that affects the inner lining of your heart chambers and heart valves endocardium. Heart infection signs and symptoms can include:.

The heart has four valves the aortic, mitral, pulmonary and tricuspid valves that open and close to direct blood flow through your heart. Many things can damage your heart valves, leading to narrowing stenosis , leaking regurgitation or insufficiency or improper closing prolapse. Depending on which valve isn't working properly, valvular heart disease signs and symptoms generally include:. Heart disease is easier to treat when detected early, so talk to your doctor about your concerns regarding your heart health.

If you're concerned about developing heart disease, talk to your doctor about steps you can take to reduce your heart disease risk. This is especially important if you have a family history of heart disease. If you think you may have heart disease, based on new signs or symptoms you're having, make an appointment to see your doctor.

Heart disease causes depend on your specific type of heart disease. There are many different types of heart disease. To understand the causes of heart disease, it helps to understand how the heart works.

A normal heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of your heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings. Your heart is a pump. It's a muscular organ about the size of your fist, located slightly left of center in your chest. Your heart is divided into the right and the left sides.

Four heart valves keep your blood moving the right way by opening only one way and only when they need to. To work properly, the valves must be formed properly, must open all the way and must close tightly so there's no leakage. The four valves are:.

Your heart's electrical wiring keeps it beating. Your heartbeat controls the continuous exchange of oxygen-rich blood with oxygen-poor blood. This exchange keeps you alive. If you have too many cholesterol particles in your blood, cholesterol may accumulate on your artery walls.

Eventually, deposits called plaque may form. The deposits may narrow or block your arteries. The plaque can also burst, causing a blood clot. A buildup of fatty plaques in your arteries atherosclerosis is the most common cause of coronary artery disease.

Unhealthy lifestyle habits, such as a poor diet, lack of exercise, being overweight and smoking, can lead to atherosclerosis. In a healthy person with a normal, healthy heart, it's unlikely for a deadly arrhythmia to develop without some outside trigger, such as an electrical shock or the use of illegal drugs.

However, in a heart that's diseased or deformed, the heart's electrical signals may not properly start or travel through the heart, making arrhythmias more likely to develop. Congenital heart defects usually develop while a baby is in the womb.

Heart defects can develop as the heart develops, about a month after conception, changing the flow of blood in the heart. Some medical conditions, medications and genes may play a role in causing heart defects. Heart defects can also develop in adults. As you age, your heart's structure can change, causing a heart defect.

The cause of cardiomyopathy, a thickening or enlarging of the heart muscle, may depend on the type:. A heart infection, such as endocarditis, is caused when germs reach your heart muscle.

The most common causes of heart infection include:. Many things can cause diseases of your heart valves. You may be born with valvular disease, or the valves may be damaged by conditions such as:. Certain types of heart disease, such as heart defects, can't be prevented. However, the same lifestyle changes that can improve your heart disease can help you prevent it, including:.
