What type of cardiomyopathy is caused by Chagas disease?
Chagas heart disease is considered an arrhythmogenic cardiomyopathy characterized by atrial and ventricular arrhythmias and a wide variety of abnormalities of the conduction system. Electrocardiographic rhythm changes are predictors of both disease severity and outcome.
What is Chagas disease and how does it cause megaesophagus?
The pathogenesis of megaesophagus in chronic Chagas disease, which is caused by infection with the parasite Trypanosoma cruzi is compelling. Individuals with megaesophagus often present achalasia and disturbances of peristalsis and neuronal loss. Esophageal samples were obtained from 6 T.
How does Chagas disease affect the esophagus?
The esophagus and the lower esophageal sphincter manifestations of Chagas disease. Chagasic achalasia and its consequence of chagasic megaesophagus are common findings in Chagas disease, and dysphagia may be the first symptom of digestive disturbances that may lead to malnutrition and severe weight loss.
What does Chagas disease do to the heart?
It is now being diagnosed in non-endemic areas due to immigration. Typical cardiac manifestations of Chagas disease include dilated cardiomyopathy, congestive heart failure, arrhythmias, cardioembolism and stroke.
Is Chagas asymptomatic?
Although most patients with chronic Chagas disease remain asymptomatic, 20% to 30% of infected people develop debili tating and sometimes life-threatening medical problems.
Can Chagas cause heart failure?
Chagas cardiomyopathy represents the most frequent and serious complication of chronic Chagas disease, affecting about 20-30% of patients, potentially leading to heart failure, arrhythmias, thromboembolism, stroke and sudden death.
Is Chagas disease a virus or bacteria?
Chagas disease is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors that are found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread). Chagas disease (T. cruzi infection) is also referred to as American trypanosomiasis.
What bug gives you Chagas?
Triatomine bugs are a type of reduviid bug that can carry Trypanosoma cruzi, the parasite that causes Chagas disease.
Can Chagas go away on its own?
Signs and symptoms that develop during the acute phase usually go away on their own. In some cases, if the infection isn’t treated, Chagas disease will advance to the chronic phase.
Is Chagas disease bacterial or viral?
Chagas disease, also known as American trypanosomiasis, is a tropical parasitic disease caused by Trypanosoma cruzi. It is spread mostly by insects known as Triatominae, or “kissing bugs”….
