Clinical trials are reshaping how doctors treat in

Clinical trials are reshaping how doctors treat intermediate-risk pulmonary embolism (PE).

Dr. Parth Rali, director of the Temple University’s Pulmonary Embolism Response Team (PERT) and NBCA volunteer, highlighted at the recent American College of Chest Physicians (CHEST) 2025 Annual Meeting that several new clinical trials are testing innovative treatment approaches, from lower-dose clot-busting drugs to advanced catheter procedures.

He predicts these trials will triple the number of randomized patients studied and mark a new era for PE treatment.

Blood clotting disorders, also called thrombophili

Blood clotting disorders, also called thrombophilias, can run in families—and knowing when and how to get tested isn’t always simple, especially if you’re already on blood thinners.

Our November PEP Talk will help you understand what thrombophilia testing involves, why it matters, and how to approach these conversations with your healthcare provider. We’ll also explore how to talk with family members who may share inherited clotting risks.

🩸At the link in bio, check out our helpful resource on shared decision making for blood clotting disorder testing.

❤️ We see you — and others are, too.

At the CHEST conference this week, we were moved by Merck’s powerful “Red Chair” exhibit — a reminder that patients belong at the center of every conversation.

Their message says it all:
“Empowering the patient community. When you’re sitting in this red chair, ask yourself — how can I prioritize patient health? How can I empower patients to engage in shared decision-making?”

At NBCA, that’s exactly why we’re here — to make sure your voices are heard, your experiences are represented, and your stories are shaping change.

Your participation in NBCA surveys, patient stories, support groups, and programs helps industry and clinicians better understand what patients really need.

Change is happening — and you’re part of it. 🫶

Elite athletes aren’t immune to blood clots. From NBA stars Damian Lillard and Chris Bosh to tennis legend Serena Williams, clots have sidelined players across every sport.

Paralympic wheelchair racing champion @TatyanaMcFaddenUSA was diagnosed with a clot in 2017 and made a remarkable comeback — returning to racing, winning medals, and advocating for blood clot awareness through the National Blood Clot Alliance.

Their stories are a reminder that anyone, even top performers in peak condition, can be at risk. 🔗 Read the piece: Link in bio!

New research shows that delays in diagnosing blood

New research shows that delays in diagnosing blood clots dramatically increase the risk of death. Nearly 80% of patients in the study waited more than 24 hours for a confirmed diagnosis, and those delays tripled mortality in some hospitals.

Blood clots often start with vague symptoms like shortness of breath, chest pain, or leg swelling. Early recognition saves lives. Trust your instincts. If something feels wrong, speak up, and advocate for urgent evaluation.

Thrombophilia testing can provide important clues

Thrombophilia testing can provide important clues about why a blood clot occurred and how to lower future risk. But deciding if and when to test—especially while on an anticoagulant—can be complicated.

Our next PEP Talk on Tuesday, Nov. 11 at 7 p.m. ET demystifies the process so you can make informed choices with your care team.

We’ll discuss:

✅ What thrombophilia testing is and the common conditions it looks for
✅ Who might benefit from testing and who may not
✅ How blood thinners and timing can affect certain test results
✅ What results can mean for treatment duration, family testing, pregnancy care, and procedures
✅ Questions to ask your clinician to decide on next steps

Join us to understand the purpose of testing and how it fits into your overall care plan. Register: Link in bio.

💔 It started with a fast heartbeat.

On a Friday in February 2021, I noticed my heart rate was racing — even when I wasn’t doing much. By Monday, I had chest pain and could barely catch my breath.

By Tuesday, something in me said go to the hospital. After nearly passing out several times in the ER, I learned the truth:
➡️ I had bilateral pulmonary emboli — blood clots in both lungs. I was scared, confused, and alone.

The doctors told me my birth control pills were likely to blame. I was admitted immediately and started on blood thinners. Later, I saw a hematologist and found out I also have Factor II gene mutation, which—combined with the pills—triggered the clots.

Since then, I’ve lived with constant anxiety — blood clots are something I’ll have to think about for the rest of my life: before travel, surgeries, even pregnancy. It can be overwhelming at times, but I’m grateful every day that I trusted my instincts and listened to my body when something felt off. I know this could have ended up much worse.

🩸 Blood clots can happen to anyone. Always trust your instincts!

Jamie’s charley horse and pressure in her chest were dismissed, leaving her feel unheard and uneasy. As her symptoms worsened, she almost didn’t get checked out because of her previous experience, but that decision to go to the ER saved her life.

Jamie feels fortunate that a friend shared Stop the Clot resources with her, including PEP Talk, and all that she learned. How did you find your way to the National Blood Clot Alliance (stoptheclot.org)? Tell us in the comments!

🧠 World Mental Health Day: Addressing the Hidden Impact of Blood Clots

Today, on World Mental Health Day, we recognize that living with blood clots, or supporting someone who is, can take a toll not just on the body—but on the mind as well. Anxiety, fear, and stress are real parts of the journey for patients and caregivers alike. If you're navigating life after a blood clot, know that you're not alone.

📝Resources are here:
- Mental Health Guide: A resource to help you begin your mental health recovery.
- PEP Talk: The Emotional Aftermath of Blood Clots: An insightful discussion on the psychological impact of blood clots.
- Facebook Support Group: A safe space to connect with others who understand your experience.
🔗Access these resources and more at the link in bio.

Remember, it's okay to not be okay. Seeking help is a sign of strength, not weakness. Reach out, share your story, and take care of your mental health—just as you do your body.
