You are not alone.

After experiencing a blood clot, it’s normal to have a lot of questions. Many people are left feeling confused about why this happened to them and anxious about it happening again. NATF is here to be your support system. We are proud to offer Boston and Chicago-based in-person support groups, as well as an online support group.

Online Support

NATF’s Online Support Group offers patients the opportunity to share common concerns, offer support to one-another, and learn up-to-date and accurate information on research in the field of VTE. Each month is hosted by a different doctor, who presents on important new information for patients with blood clots.

NATF invites different physicians to serve as our moderators each month, with each presenting their own updates in thrombosis medicine and offering new perspectives. Join us and other blood clot survivors for these rewarding and educational events. Family members and friends of those dealing with blood clots are also invited to attend. All you need to join is a computer with internet access or phone!

Each meeting starts with a meet-and-greet for the first half hour during which time attendees can visit the compression and Coumadin corners. Then we have a short 20 minute presentation on a pertinent topic such as:

  1. Genetic blood disorders
  2. DVT/PE risk factors
  3. DVT/PE prevention
  4. DVT/PE symptoms
  5. Life changes after a DVT/PE

The meeting features an anticoagulation clinic corner staffed by pharmacists from the three anticoagulation clinics at NorthShore University HealthSystem. Attendees can visit the clinic corner and get information on anticoagulant drugs particularly Coumadin.

There is also a stocking/compression corner featuring expert fitters, to answer questions and concerns as well as demonstrate a variety of products that can be helpful for patients with leg swelling, blood clots, and the ever-popular travel-related stockings.

History of NATF’s Blood Clot In-Person Support Groups

For 24 years Dr. Samuel Z. Goldhaber (NATF President) and Ruth Morrison, RN, BSN (member, NATF Patient Advocacy Committee) have held a monthly venous thromboembolism (VTE) Support Group at Brigham and Women’s Hospital. A typical meeting has between 10-15 patient attendees. Our attendees represent all stages of recovery: some have suffered a thromboembolic event decades ago and enjoy coming to the meeting to learn new information and lend support to other patients; others are newly diagnosed and still overwhelmed with their diagnosis and onslaught of new information. We have enjoyed a diverse mix of both men and women, young and elderly (ages range from 17 to well into the 80s). The feedback we receive from our attendees is that the support group has been invaluable to their recovery, both physically and mentally:

  • “Having a doctor explain the new drugs on the market in a way I can easily understand them has helped me to have discussions with my doctor about the best treatment for me.”
  • “Learning about the disease and that others have the same problems. That there is help and support close by.”
  • “Knowing that life goes on pretty much as before for the vast majority of patients with only minimal daily inconveniences.”
  • “I like hearing about the current status of research in this area.”
  • “It was extremely beneficial for me to hear that others had similar fears that I had. Just being able to express these fears and feelings to others was a tremendous help to me.
