Hello!
Welcome on HCM!
Regarding your concern, I would explain that
chest pain that is triggered by deep breathing and walking indicates an extracardiac cause (musculo-skeletal pain,
costochondritis, inflammation, pleuritis,
pericarditis).
It is not related to coronary artery disease.
Anyway, I would recommend performing some tests to investigate for the possible underlying causes:
- a chest X Ray study
- a resting ECG
-
complete blood count, PCR, ESR for inflammation
- a resting ECG and a cardiac ultrasound to examine your heart.
An ambulatory 24-48 hours ECG monitoring would help exclude possible
cardiac arrhythmia underlying your palpitations. Other tests (thyroid hormone levels, blood electrolytes) are necessary to exclude possible metabolic causes that can lead to palpitations.
Hope to have been helpful!
Kind regards,
Dr. Iliri
