Today, on National Doctors’ Day, we recognize the clinicians who go beyond treating conditions to truly *listen, learn, and partner* with patients.

“What drew me to NBCA was its unwavering commitment to placing patients at the center of everything it does,” said Dr. Rushad Patell, Chair of NBCA’s Council of Emerging Researchers in Thrombosis (CERT).

“The organization does more than raise awareness. It builds meaningful partnerships between patients, clinicians, and researchers. Since I began working with them, my own work has been truly enriched by perspectives I had not fully appreciated before.”

At NBCA, we believe better outcomes start with collaboration—and we are grateful to work alongside physicians who are committed to learning from and with the patients they serve.

Thank you for all that you do to help stop the clot. 🩸

Lucy is a 3x DVT survivor. Her story started durin

Lucy is a 3x DVT survivor. Her story started during pregnancy, when warning signs were there, but attempts to get them looked into were to no avail.

After an emergency C-section, she had pain in her left leg and assumed it was related to the surgery. About a week later, it got so bad that no amount of raising it or pillows made her feel better — she was dragging her leg.

She didn’t know what a blood clot was, but she knew something was wrong.

At the hospital, she was diagnosed with a DVT, and later with Factor V Leiden and Factor II.

Her later clots didn’t look how you’d expect — no swelling, no redness, no severe pain. It just felt like she pulled a muscle.

Her message is clear: ALWAYS listen to your inner voice or intuition. Don’t wait — go directly to the emergency room.

Mia never expected nausea and a strange pain in he

Mia never expected nausea and a strange pain in her chest to be signs of something life-threatening.

After being sent home from the emergency department despite severe symptoms, she trusted her instincts and sought a second opinion. A CT scan soon revealed multiple pulmonary embolisms in both of her lungs. Doctors later told her she had been a “ticking time bomb.”

Having taken the combined birth control pill for many years, Mia had no idea she could be at risk for blood clots.

Today, she is incredibly grateful to be alive and is using her experience to educate others about the importance of self-advocacy and recognizing the signs of blood clots.

“If something doesn’t feel right, advocate and seek a second opinion.”

New research led by NBCA MASAB member Dan Witt, PharmD, FCCP, BCPS shows that with the right training and support, some patients can safely manage their own warfarin dosing—highlighting the power of patient education, self-advocacy, and shared decision-making in blood clot care.

On World Adherence Day, it’s an important reminder:
Adherence isn’t just about taking medication—it’s about understanding your treatment, staying engaged, and being an active partner in your care.

Whether your care is managed in a clinic or at home, the goal is the same: safe, consistent, and effective treatment.

🩸 Understanding your care can save your life.

For blood clot survivors, knowing why your treatment matters makes it easier to stay on track—and staying on track can help prevent another clot.

Today is World Adherence Day (March 27), an initiative led by the World Heart Federation, and we’re highlighting the life-saving importance of sticking to your care plan. This global movement is all about empowering patients to take an active role in their health and “not miss a moment” that matters most.

Because when survivors have clear information, strong support, and open communication with their healthcare team, they’re better equipped to manage their health—and protect their future.

Together, we can turn knowledge into action—and action into protection.

Finley was a healthy, driven high school athlete with big dreams — football, computer science, even teaching himself Japanese.

He had been diagnosed with Factor V Leiden, but no one explained what that meant. When he started showing symptoms like shortness of breath, high heart rate, and difficulty climbing stairs, but his symptoms were not taken seriously.

On October 1, Finley collapsed at school due to a massive saddle pulmonary embolism. He passed away days later.

His story is a reminder: blood clots don’t just affect adults—and too often, the signs are missed, especially in young athletes.

Know your family history. Recognize the symptoms. Don’t be afraid to push and question your doctors.

Blake Burgess was 21 years old when a blood clot took his life. 💔

Now, Oklahoma has a chance to make sure fewer families face that same heartbreak.

HB 3644 — the Blake Burgess Blood Clot Prevention Act — has passed the House and is headed to the Senate. It would require Oklahoma hospitals to screen patients for blood clot risk and train their staff to act fast. This is how we save lives.

Oklahoma: momentum is building.

550+ letters have already been sent in support of HB 3644. Contact your State Senator and ask them to vote YES.

Trey Smith is a 2x Super Bowl Champion — but bef

Trey Smith is a 2x Super Bowl Champion — but before the NFL, he faced something far more life-threatening than any opponent on the field.

He couldn’t walk a few yards without struggling to breathe. Training felt different. Something wasn’t right.

Many athletes are taught to push through pain. To ignore it. To keep going.

But Trey listened to his body. He spoke up. He asked questions.

And that decision saved his life.

This Blood Clot Awareness Month, we’re sharing stories like Trey’s to remind you:
Being strong isn’t about pushing through —
it’s about knowing when to speak up.

💬 Ask when something feels off
💬 Ask about your risk
💬 Ask until you’re heard

That’s what it means to be #StrongEnoughToAsk.

Trey is using his voice to help others — and you can too.

Join the 100,000 Reasons Challenge, or support someone who is.

🏃🏼‍♀️ Move for awareness.
🚴🏾 Move for your physical and mental health.
🛼 Move so fewer lives are lost.

Lauren Brzozowski is an elite Team USA bobsled ath

Lauren Brzozowski is an elite Team USA bobsled athlete, known for her speed, strength, and determination on the ice. But despite being in peak physical condition and training at the highest level, she developed blood clots in her calf after suffering an injury and traveling long distances to compete.

At first, Lauren struggled to understand what was happening. As a high-performance athlete, she was used to pushing through pain and discomfort. But this felt different. What began as leg pain and swelling turned out to be something far more serious — deep vein thrombosis (DVT). Because blood clots are often not top of mind for young, healthy athletes, the warning signs can be easy to overlook. Thankfully, Lauren received medical care and began treatment that allowed her to safely return to training and continue pursuing her Olympic dreams.

Now Lauren is using her experience to help others understand that blood clots can happen to anyone — even elite athletes. This March, her story is a powerful reminder that no one is invincible, and that being “Strong Enough to Ask” and getting checked when something feels off can save your life.

Join Lauren and the NBCA community in the 100,000 Reasons Challenge. Together we’ll get up, walk, run, ride, and roll, tracking and sharing our progress along the way. It’s not too late to join!

🚶🏽‍♂️‍➡️ Move for remembrance.
🏃🏼‍♀️ Move for awareness.
🚴🏾 Move for your physical and mental health.
🛼 Move so fewer lives are lost.
