Symptoms of Heart Infection: Early Signs and Complications

Heart Infections: Warning Signs and Potential Complications

Heart infections are dangerous diseases caused by irritative agents such as bacteria, viruses, or fungi colonizing the heart. The pathologic conditions include endocarditis, myocarditis, and pericarditis, with each referring to the specialization of the disease to a particular part of the heart.

Understanding the heart infection warning signs may be of major benefit. Early diagnosis and intervention whether by medical or surgical means can greatly enhance the quality of life of the sufferers.

This blog talks about heart infection symptoms, and causes, guiding you on what to watch for. Keep reading to know more in-depth details about it!

What is a Heart Infection?

Heart infections can be defined as infections that affect the heart structures and are generally caused by bacteria, viruses, fungi, or other microorganisms, which result in inflammation.

Like other parts of the body, the heart is susceptible to infections and eventually adversely impacted by inflammation. Such microbes could be bacteria, viruses, or fungi. As a result of these infections, inflammation and structural damage may occur in vital components of the heart.

The areas most commonly impacted include:

• Heart muscle (myocardium)
• Heart valves
• Inner lining (endocardium)
• Outer membrane or sac (pericardium)

In heart infections, the damage is most upsetting as the infection alters the heart muscle tissues leading to ruptured blood flow. Unlike general heart disease, which includes conditions like coronary artery disease (CAD) or arrhythmia, heart infections directly harm heart tissues.

Types of Heart Infections

Heart infections can affect different parts of the heart. The main types of heart infections are as follows:

• Endocarditis: It is often caused by bacteria, an infection of the inner lining of your heart valves. It's also called bacterial endocarditis or infective endocarditis.
• Myocarditis: Myocarditis causes inflammation in the heart muscle. This weakens the heart and also affects its ability to pump blood.
• Pericarditis: In this type of infection, inflammation occurs in the outer sac that covers your heart.

In addition to infections, certain conditions like dilated cardiomyopathy, hypertrophic cardiomyopathy, and restrictive cardiomyopathy can also affect the heart. These conditions can be inherited or have no known cause and can lead to complications over time.

What Causes a Heart Infection?

There are different causes of heart infection, each depending on the specific type of infection. However, every type has its common causes, and knowing them could help with early detection:

1. Endocarditis

• Poor Dental Hygiene: Bleeding gums allow bacteria to reach the bloodstream.
• Dental Procedures: Cuts in the gums during treatments can introduce bacteria.
• Catheters: Bacteria can be transferred through tubes during a medical procedure
• IV Drug Use: Sharing needles increases the risk of bacterial infection.

2. Pericarditis 

• Viral Infections: Respiratory and gastrointestinal viruses are common culprits.
• Bacterial Infections: Tuberculosis is a more common cause in some countries.
• Fungal and Parasitic Infections: These can also lead to pericarditis.

3. Myocarditis

• Viral Infections: COVID-19, coxsackievirus, and parvovirus can also lead to heart infections.
• Bacterial Infections: Streptococcus and Staphylococcus bacteria can affect the heart muscle.
• Fungal and Parasitic Infections: Infections from mould, yeast, and parasites, especially in South America, are factors.

Identifying the heart infection causes of these heart infections is crucial for preventing severe complications.

Common Symptoms of Heart Infections

Heart infection symptoms treatment depends on the type and severity. While some signs are general, others are specific to the infection. 
Common viral heart infection symptoms and general signs include:

• Chest pain: Discomfort in the chest.
• Fatigue: Unusual tiredness or lack of energy.
• Fever: Often accompanied by chills.
• Fluid Buildup (Edema): Due to this, swelling in the legs, ankles, feet, or abdomen occurs.
• Joint Pain or Body Aches: Aches across the body, often resembling flu-like symptoms.
• Night sweats: Excessive sweating during the night.
• Rapid or Pounding Heartbeat: Known as arrhythmia or heart palpitations.
• Shortness of Breath (Dyspnea): Dyspnea leads to difficulty in breathing.

Endocarditis is a type of heart infection with its own set of symptoms:

• Blood in Urine (Hematuria): Presence of blood in the urine.
• Petechiae: In petechiae, small red or purple spots appear on the skin, mouth, or even eyes.
• Janeway Lesions: These cause red spots on the bottom of your feet or palms.
• Osler's Nodes: You can see that there are red spots under the skin of your toes or fingers.
• Spleen Tenderness: Pain or discomfort in the spleen area.

Potential Complications of Heart Infections

Heart infections, if left untreated, can lead to severe complications. These complications can impact your overall health and may even be life-threatening.

Some common complications of heart infections include:

• Heart Failure: This is the case when the heart cannot pump enough blood to meet the body's criteria.
• Heart Attack: This occurs when a blood clot or plaque in the arteries blocks blood flow to the heart.
• Stroke: A heart infection increases the risk of ischemic stroke caused by narrowed or blocked arteries leading to the brain.
• Aneurysm: A bulge in an artery's wall. If it bursts, it can cause dangerous internal bleeding.
• Peripheral Artery Disease: This condition reduces blood flow to the limbs, especially the legs, causing pain and discomfort, often during walking.
• Sudden Cardiac Arrest: A medical emergency that happens when the heart suddenly stops beating, leading to loss of consciousness and breathing.

These complications highlight the importance of monitoring heart health and seeking prompt medical attention when symptoms arise.

How is a Heart Infection Diagnosed?

Diagnosing a heart infection involves a combination of tests and a thorough evaluation by your healthcare provider. The process begins with looking for symptoms and medical history, including any family history of heart disease.

Your doctor may also listen for a heart murmur using a stethoscope, which is a key indicator of heart infections like endocarditis.
Critical tests for diagnosing a heart infection include:

• Blood Tests: These help detect signs of infection or inflammation, such as elevated white blood cells or inflammatory proteins. They may also check for antibodies related to viral infections.
• Chest X-Ray: This can show changes in the size and shape of the heart, as well as signs of fluid buildup.
• CT or MRI Scans: These provide detailed images of the heart to detect inflammation or thickening of heart tissues.
• Cardiac Catheterization: In some cases, a catheter is inserted into a vein to take a tissue sample (biopsy) from the heart for analysis.

Additional tests that may be used to assess heart function and detect heart disease include:

• Electrocardiogram (ECG): It is a test that is used to check the heart's electrical activity.
• Echocardiogram: This non-invasive test uses sound waves to create images of the heart in motion, showing blood flow and heart valve function.
• Holter Monitoring: A portable device that records heart activity over time, detecting irregular heartbeats.
• Stress Tests: These tests monitor the heart's response to physical activity, helping identify symptoms that appear during exercise.

Treatment Options for Heart Infections

Heart infection treatment includes different options depending on its cause as well as its severity. For the most part, heart infections are dealt with by using medication. The common effects include:

• Antifungal Medications: For fungal heart infections.
• Antibiotics: To treat bacterial infections.
• Colchicine: A medication to reduce inflammation.
• Corticosteroids: To control severe inflammation.
• Heart Medications: To manage symptoms or underlying heart conditions.
• High Blood Pressure Medications: To control hypertension.
• Medications for Chronic Conditions: Conditions like rheumatoid arthritis or lupus that need immediate medications.
• Nonsteroidal Anti-inflammatory Drugs (NSAIDs): These drugs help to reduce pain and inflammation.

In severe cases, when medications are not effective, heart surgery may be necessary. The type of surgery performed would depend on the specific heart infection, and in more severe cases, valve surgery may be performed, and transplant surgery is a possibility.

Preventive Tips for Heart Infections

Although everyone suffering from heart disease is at risk of a heart infection, there are interventions that can help in minimizing or reducing one's risk of developing a heart infection. Let's take a look at some of the significant protective measures you should consider adopting:

• Avoid Viral Infections: Try to avoid close contact with people who are suffering from viral infections.
• Get Vaccinated: Stay up to date with recommended vaccines, including COVID-19 and flu shots.
• Avoid Recreational Drugs: These can facilitate the invasiveness of infections to the heart.
• Limit Exposure to Certain Risks: Avoid high-risk areas where you can be infested with ticks or areas with lots of birds.
• Schedule Regular Dental Visits: Good hygiene related to the mouth can prevent bacteria and other infectious agents from accessing the heart.
• Take Antibiotics as Needed: Follow your provider's advice for antibiotics before medical or dental procedures, especially if you have a history of heart valve issues.
• Practice Hand Hygiene: Wash your hands regularly to reduce the likelihood of infection.
