Polymyositis & Dermatomyositis Support Group
Polymyositis (PM) is a type of chronic inflammation of the muscles (inflammatory myopathy) related to dermatomyositis and inclusion body myositis. The inflammation is predominantly of the endomysium in polymyositis, whereas dermatomyositis is characterized by primarily perimysial inflammation.

My speech seems slow and I have been told that I sound tired all of the time. I was told that a speech therapist may be able to help me. I know that I sound older and as if I have lost my pep. I never know what I am going to sound like when I speak with someone and I work on the phone all day so that doesn't sit well with me. I was examined by a cardiologist while in the hospital and he told me that there was nothing wrong with my heart.
Respiratory problems from interstitial lung disease (ILD)are a symptom of one subset of myositis called anti-synthetase syndrome. This is most commonly found in people who have anti-Jo-1 antibodies or some less common myositis antibodies that fall into the anti-synthetase category. Cardiac problems are much less common, and are usually in the form of pericarditis due to inflammation. Shortness of breath and sharp chest pain are typical symptoms.
When I was first got sick I had significant problems with shortness of breath but no chest pain or other cardiac symptoms. My rheumy ordered a high resolution CT of the lungs and a cardiac CT as part of the diagnositc work-up. These tests were negative for ILD and pericarditis, but the HRCT showed that my diaphragm was very weak, which accounted for the shortness of breath.
Since the HRCT was negative for ILD and I didn't have anti-Jo-1 or other antisynthetase antibodies (mine are anti-Mi-2), my rheumy didn't think a full pulmonary work-up was necessary. And since the cardiac CT was normal and I didn't have any chest pain, a full cardiology work-up wan't indicated either. These are all the things that you and your doctor need to consider when deciding whether you should be referred to a cardiologist or pulmonologist. Once you get there, it's almost a given that they'll order a bunch of expensive, annoying, and maybe unnecessary tests just because they can.
I know all this can be confusing and overwhelming. You're doing exactly the right thing by asking a lot of questions here. Keep up the good work!
