[Coronary Artery Disease Secondary to Hyperlipidemia]

I am in the same exact situation.  I had a NSTEMI MI in June 2017.  I have records from military and VA doctors with test results for hyperlipidemia.  Had 2 stents put in in June and another in Oct.  Have yet to have METs test(s), dont think I can since I cant even take a hot shower or walk up a flight of stairs without chest pains and shortness of breath.  I also have back and sciatica in both legs, plus knee injury which prevents me from working out or exercising for past 17 years.  I have filed for CAD and  MI but I will not see my Cardio doctor again until June, and I plan on pursuing nexus letter for hyperlipidemia and sedentary lifestyle due to a service-connected injury.  I would like to note, I was never told, briefed or informed of hyperlipidemia by the military nor the VA, nor was I ever treated.  Shame I could have avoided CAD and MI if I was.

[Have claim for lower back and wonder if they use the second range of motion?]

Based on what you have said, the examiner should take the worst case.  However, you never know what the doctors will do or the people reviewing the claims.  I have had this issues after five C and P for my back.  Last time I took records from my own doctor when they measured me after a flare up and it is night and day difference.  I have never seen such a cluster and mess but when it comes to back injuries and C and P exams.  For example, I never claimed sciatica, after my exam and rating, they gave me 20% for the left leg.  Yes, I have issues with my left, but my right leg is 100 times worse.  I refiled a few weeks later C and P exam again, three days later they approved 20% for my right leg.  Granted, I never claimed either, I claimed thoracic and cervical issues with nerve damage in my neck into my arms and hands, they rated my legs......go figure
