I would explain as follows:
Detailed Answer:
Hello!
Welcome and thank you for asking on HCM!
I carefully passed through your question and reviewed all your uploaded reports.
Your symptoms seem to be related to right heart dysfunction, which has also been confirmed by your cardiac ultrasound which reveals a dilated right ventricle.
All the above clinical presentation raises suspicions of important pulmonary disease. As your left heart function and structure is normal, a bronco-pulmonary disease or a bronco-vascular (thromboembolic)disease.
As I mentioned you above it is important differentiating between these two pulmonary disorders. In this regard besides a careful physical exam, chest X ray study, some additional tests are necessary as follows:
- pulmonary function tests
- pulmonary angio CT (possibly better a double rule out protocol to include also coronary artery investigation).
- lung ventilation-perfusion scan
Some blood lab tests are also necessary :
- complete blood count
- arterial blood gas analysis
- AST, ALT
- BUN, creatinine
- D-Dimmer
- inflammation tests.
Meanwhile, I recommend you to follow your doctors advice and treat your other risk factors (hypertension, diabetes, dyslipidemia and sleep apnea), whose proper management would help improve your clinical situation.
Hope you will find this answer helpful!
Feel free to ask any other questions whenever you need!
Kind regards,
Dr. Iliri
