I had Chagas disease or lived in a Chagas area: do I need a cardiologist?

Reviewed by Dr. Rebeca Granada, cardiologist · RP 17.697 · 13/10/2026

What many people think

Without symptoms, many people think Chagas no longer matters.

Why it may be related to the heart

Chagas disease can affect the heart many years after infection, without symptoms at first.

When to see a cardiologist

If you had Chagas, tested positive, or lived in an area with kissing bugs.

Tests usually ordered

Electrocardiogram (ECG)
Echocardiogram (depending on the case)
24-hour Holter (depending on the case)

24-hour Holter at home in Asunción

Frequently asked questions

I feel fine. Do I still need check-ups?

Yes. An ECG can show changes before symptoms appear.
