Overview
Natural History, Complications and Prognosis
Complications
Complications of Chagas disease include:
- Myocarditis
- Meningoencephalitis
- Congestive heart failure
- Apical aneurysm
- Thromboembolism
- Sudden death
- Esophagitis
- Esophageal cancer
- Fecaloma
- Volvulus of sigmoid colon
Prognosis
An index for classification of patients who have Chagas' disease was published in the August 24, 2006 edition of the New England Journal of Medicine.[1] Based on over 500 patients, this index includes clinical aspects, X-ray findings, EKG, echocardiography and Holter.
| Risk Factor | Points |
|---|---|
| NYHA class III or IV | 5 |
| Cardiomegaly | 5 |
| Wall motion abnormalities | 3 |
| Non-sustained ventricular tachycardia | 3 |
| Low voltage on ECG | 2 |
| Male gender | 2 |
| Total Points | Risk of death in 10 years |
|---|---|
| 0–6 | 10% |
| 7–11 | 40% |
| 12–20 | 85% |
