Infective Endocarditis

Information about Infective Endocarditis

We have to know about Infective Endocarditis

  • Infectious endocarditis is an infection of the lining of the heart chambers and heart valves, caused by bacteria, fungi, or other infectious agents.

Causes of Infective Endocarditis

  • Most people who develop infectious endocarditis have underlying heart disease.
  • Endocarditis is usually a result of bacteremia (bacteria in the blood), which is common during dental, upper respiratory, urologic, and lower gastrointestinal diagnostic and surgical procedures.
  • The bacteria in the bloodstream can settle on damaged heart valves, and grow to create a “vegetation” or clump of live bacteria.
  • These growths may form infected clots that break off and travel to the brain, lungs, kidneys, or spleen.
  • Many bacteria can cause endocarditis in patients with underlying valve problems
  • Since Streptococcus viridans is often found in the mouth, dental procedures are the most common cause of bacterial endocarditis.

Do’s and Don’ts of Infective Endocarditis

  •  Consult the doctor

Signs & Symptoms of Infective Endocarditis

Medical advice for Infective Endocarditis

See a doctor if you note the following symptoms during or after treatment:

  • Weight loss without a change in diet
  • Blood in urine
  • Chest pain
  • Weakness
  • Numbness or weakness of muscles
  • Fever

Risk factors of Infective Endocarditis

Preexisting conditions that increase the likelihood of developing endocarditis include:

  • Congenital (present at birth) heart disease (atrial septal defect, patent ductus arteriosus, and others)
  • Prior rheumatic heart disease
  • Cardiac valve anomalies (such as mitral insufficiency)
  • Artificial heart valves

Treatment for Infective Endocarditis

Antibiotics and initial treatment

  • While in the hospital, your vital signs will be monitored. You will be given antibiotics intravenously (IV). Once you go home, you will continue with oral or IV antibiotics for at least four weeks. During this time, you will keep visiting your doctor. Regular blood tests will check that the infection is going away.

Surgery

  • Surgery may be needed if your heart valves have been damaged. Your surgeon may recommend repairing the heart valve. The valve can also be replaced using a new valve made from either animal tissue or artificial materials.
  • Surgery may also be necessary if the antibiotics are not working or if the infection is fungal. Anti-fungal medications are not always effective for infections in the heart

Self-care for Infective Endocarditis

  • Consult the doctor immediately after you observe symptoms

Investigations for Infective Endocarditis

  • Blood Culture
  • ESR
  • Echo-cardiogram
  • Chest X-Ray
  • CT Scan of chest
