Yes, Chagas disease is a significant cause of cardiovascular disease (CVD), leading to chronic heart damage (cardiomyopathy) in 20-30% of infected people, resulting in heart failure, arrhythmias, sudden cardiac death, and stroke. It's a leading cause of infectious cardiomyopathy and heart-related mortality, causing inflammation and fibrosis in the heart muscle, damaging the electrical system, and leading to heart failure, dilated cardiomyopathy, and arrhythmias.
Chagas (CHAH-gus) disease is an illness caused infection with the parasite Trypanosoma cruzi. The parasite is found in the feces of the triatomine bug. These bugs also are called reduviid. They may also be known as "kissing bugs" because they tend to bite people's faces.
Types of CVD
Background: Chagas disease, resulting from the protozoan Trypanosoma cruzi, is an important cause of heart failure, stroke, arrhythmia, and sudden death.
Lyme carditis is a rare infection that occurs when Lyme bacteria enters your heart tissue. The bacteria affects your heart's electrical system. Your heartbeat slows, and electrical signals have trouble traveling from your heart's upper chambers to the lower chambers. Doctors call this condition heart block.
Lyme disease is classified as a zoonosis, as it is transmitted to humans from a natural reservoir among small mammals and birds by ticks that feed on both sets of hosts. Hard-bodied ticks of the genus Ixodes are the vectors of Lyme disease (also the vector for Babesia).
Many in the public eye live or work in high-risk areas: wooded estates in the Northeast, mountain retreats, or rural film sets. Exposure isn't about fame. It's about geography and climate. That's why celebrities with Lyme disease serve as a reminder that tick-borne infections cross every social and financial boundary.
Classically, CHD is diagnosed when the patient presents with a positive serological or parasitological test for T. cruzi and ECG shows typical CHD changes in the absence of other heart diseases that may cause these changes[9].
Lyme carditis is the most well-known cardiac manifestation of tickborne illnesses. However, there exist a multitude of other tickborne infections associated with myocarditis. We present a case of fulminant myocarditis following a tick bite which highlights this diagnostic challenge.
The heart is the most commonly affected organ. In the acute phase of Chagas disease, cardiac involvement may be mild to severe, and is fatal in 3–5% of patients. In the latent phase, which is typically very prolonged (10–30 years), cardiac involvement is usually minimal or absent.
Cardiovascular disease generally refers to 4 general entities: CAD, CVD, PVD, and aortic atherosclerosis. CVD is the main cause of death globally. Measures aimed to prevent the progression of atherosclerosis are the hallmark for primary prevention of CVD.

The 12 most common heart and cardiovascular conditions and what you can do about them
Your healthcare professional does a physical exam, asking about your symptoms and anything that put you at risk of Chagas disease. If you have symptoms of Chagas disease, two or more blood tests can confirm the diagnosis. If you're diagnosed with Chagas disease, you're likely to have more tests.
Scientists think that in the United States there are at least 300,000 cases of Chagas disease in people, and there may be more than 1 million cases. Most states are not required to keep track of the number of people with Chagas disease.
Malaria Parasite (Plasmodium)
Not only a killer parasite, but one of the world's biggest killers, the malaria parasite is responsible for around 600,000 deaths a year.
Lyme carditis occurs when Lyme bacteria that have disseminated in the blood establish infection in heart tissue. Lyme carditis usually occurs in association with joint or nervous system manifestations, although the heart may be the only site of clinically apparent disease.
A rare form of heart disease, myocarditis develops when the heart muscle becomes inflamed and enlarged, thus weakening the heart. Naturally, the risk of sudden death for people with myocarditis is a reason for concern.
Three early warning signs of heart failure include persistent fatigue/weakness, shortness of breath (especially with activity or lying down), and swelling in the legs, ankles, or feet (edema), which occur as the heart struggles to pump blood efficiently, leading to fluid buildup and reduced oxygen to tissues. Other signs are a rapid/irregular heartbeat, persistent cough (especially with pink/white mucus), and unexplained weight gain.
In the heart, the disease can cause enlargement of the heart muscle, leading to heart failure. Other common problems are arrythmias and sudden cardiac arrest. In the gastro-intestinal system, there can be enlargement of the colon or the oesophagus, leading to digestive problems.
Many different tests are used to diagnose heart disease.
Cardiomyopathy symptoms can include:
Justin Timberlake has Lyme disease, a bacterial infection spread by ticks, which he revealed in mid-2025, describing it as "relentlessly debilitating" and causing significant fatigue, nerve pain, and sickness, impacting his recent tour. Lyme disease is treatable with antibiotics, especially if caught early, but can become severe if delayed, affecting the joints, heart, and nervous system.
Objectives: The "Rule of 7's," a Lyme meningitis clinical prediction rule, classifies children at low risk for Lyme meningitis when each of the following 3 criteria are met: <7 days of headache, <70% cerebrospinal fluid (CSF) mononuclear cells, and absence of seventh or other cranial nerve palsy.
Twain started to believe that she would never be able to sing again. However, after she underwent two "open throat" vocal cord surgeries, along with vocal therapy, she started to get her voice back.
