What is the main cause of breathlessness and left arm and neck pain?

Hello,

Welcome to icliniq.com.

I understood your concern.

Breathlessness can be explained by the history of bronchiectasis. But cardiac cause should always be ruled out. Have you ever felt chest pain? I suggest doing a stress echo test.

Hope this helps

Thanks and regards.

Hello,

Welcome back to icliniq.com.

If the stress echo is positive, then conservative treatment with blood thinners and lipid-lowering drugs can be continued but if it comes back negative then the blood thinner should be stopped.

Another non-invasive method is CT (coronary angiography), but again that will require contrast sturdy injection.

In my opinion, stress echo should be done first, it has got high sensitivity to detect heart disease.

Hope it helps.

Thanks and regards.
