Hello!
Welcome and thank you for asking on HCM!
His symptoms could be relate to different possible causes (coronary artery disease,
cardiac arrhythmia,
thyroid dysfunction,
electrolyte imbalance, IBS, etc.).
For this reason, I would recommend consulting with his attending physician for a physical exam and some tests to investigate for the possible causes:
- a chest X ray study and pulmonary function tests
- a resting ECG and cardiac ultrasound
-
complete blood count, PCR, ESR for inflammation
- thyroid hormone levels
- blood electrolytes
- an ambulatory 24-48 hours ECG monitoring would help investigate for possible cardiac arrhythmia.
An exercise cardiac stress test would help investigate for possible coronary artery disease, especially when considering his cardio-vascular risk factor (
hypertension, diabetes, overweight, age).
You should discuss with your doctor on the above issues.
Hope you will find this answer helpful!
Wishing good health,
Dr. Iliri
