Good morning, @cweible19782006 Let’s get you Connected with some fellow members who also have Essential Thrombocythemia. ET is usually a very slowly developing condition where the bone marrow can start overproducing platelets. It’s in a category of blood cancers called Myeloproliferative Neoplasms where any of the blood components can be affected. I’m sure you’ve been pouring over information to find out as much as you can about your diagnosis.
Here are a few more informational articles for you:

We have several conversations in the group with fellow members, @eileen11108 @1995victoria @rjgregory440 @chetalbin @annetterzam and many others in this discussion on jak2 mutations. That genetic mutation can contribute to ET developing. You may or may not have that but the treatments can be similar.

~Essential Thrombocythemia: Looking for information and support

These are just a few to get you started. You can always type in key words such as ET, Essential Thrombocythemia, MPN (myeloproliferative neoplasms) in the search bar and it will bring up several more discussions.

If you haven’t already, I’d urge you to see a hematologist oncologist who specializes in blood cancers. This is treatable but it needs the correct diagnosis. Have you had any genetic testing done to see if you have the JAK2 mutation?

I'm sorry I can't really help you. I was diagnosed in October and put on high dose aspirin. In January I started taking hydroxyurea, 1 a day. Last week they have doubled my dose every other day. I do not know all the side effects yet and I do not have to concern myself about going to work as I'm retired. I don't know if the problems I'm having now are side effects of the hydroxyurea.

I have had ET for about 15 years. Also mitral valve prolapse associated with severe scoliosis. The mitral valve will need repair in the next few years. Recently discovered something is also going sideways with my thyroid and glucose levels.

What I learned is that you can get all this sorted out, but it takes time. A lot of time. It's an exercise in developing patience and learning how to enjoy life despite these things hanging over your head.

A pitfall of the American health care system is that your GP coordinates care, but you end up going to several specialists and they tend to stay in their lanes and don't really look at how one issue impacts other morbidities.

You really have to keep reminding your docs about the big picture and nudge them to think holistically. If you've found out your ET affects your heart condition, you are ahead of the game!

Hi, I just read your post and am sorry that you are having a tough time right now. We’ve all been there, especially when first diagnosed. It does get better so hang in there! I used to have yearly bloodwork and was concerned about my increasing platelets over a 3 year period which then became elevated above normal levels. I was lucky though, my dad was a family practitioner, and I brought it to his attention first, and he told me that I needed to see a hematologist. My dad was not happy with my doctor for not referring me earlier. I was diagnosed before the JAK II enzyme was discovered. The doctors used to run every test imaginable, and if you were negative for every other blood disorder, but still had high platelets, then you were given the diagnosis of essential thrombocythemia. I was diagnosed at age 45. Went on treatment at age 50 and am now 66 years old. I have been on Hydroxyuria 500 mg., 5 days a week for 16 years now. We all have different dosages as the doctor has to see what works best for you and your blood levels. I think it took about 2-3 months to figure out the correct dosage for me so I was going to the doctor every week or two to check my platelets to see how it was responding to the medication. I have also been taking two baby aspirin daily for about 20 years. I feel great, just a little tired and have had no problems. I’m still working. Best of luck to you!!!

Thanks for the encouragement! I'm just worried because I fear that I've had this for a long long time. I had a hemorrhagic stroke when I was 24 caused by a vertebral dissection and we never knew why it happened and I've always had chest pain ect and then in 2018 I had another dissection of the vertebral artery and didn't know why. Then 2 years ago I was diagnosed with CAD and had 2 stents placed in my LAD and still have 50% in my RCA and was recently diagnosed with the cardiac microvascular disease which is the slow flow of blood into my heart. Now I am short of breath constantly and have chest pain pretty much all of the time. I've always been on a full adult aspirin and had previously taken plavix for my stents. So hopefully with knowing what we know now I can get on the right meds. I just hope it's not to late for me....
