🌻 In loving memory of Kelley Syron 🌻

On a sunny morning in Palm City, FL, friends and family came together for the annual walk honoring Kelley Syron — a vibrant, compassionate young woman whose life was tragically cut short at age 34 by a pulmonary embolism following a routine surgery.

Kelley dedicated her career to helping children and families through her work at The Children’s Therapy Center, where she was known for her kindness, empathy, and unwavering commitment to others. Her legacy of care and compassion continues to inspire everyone who knew her.

This year’s walk, organized by her mother Suzan Syron-Singh, brought together twice as many participants as last year and raised more than $6,100 for the National Blood Clot Alliance! Participants wore yellow shirts with sunflowers — Kelley’s signature flower — symbolizing her warmth, optimism, and the light she continues to bring to others.

In Florida, where Kelley’s family and friends continue to honor her memory, the passage of the Emily Adkins Family Protection Act this summer represents hope and progress.

Like Kelley, Emily died of a preventable blood clot after a routine procedure. This landmark law will help hospitals and clinicians better identify, prevent, and report dangerous blood clots so more families don’t have to experience the same loss.

Thank you to Suzan and everyone who helped make this beautiful event possible, celebrating Kelley’s memory and helping raise awareness about life-threatening blood clots. 💛

As #TeamStopTheClot gets ready for the @nycmaratho

As #TeamStopTheClot gets ready for the @nycmarathon on Sunday, we’re revisiting one of our most powerful stories from Taking a Breath: A Stop the Clot Podcast.

Professional distance runner and ultramarathoner @sagecanaday — who coached this year’s marathon team — faced an unexpected challenge in 2021 when what seemed like back pain and shortness of breath turned out to be a pulmonary embolism.

Sage’s story is a reminder that blood clots can happen to anyone, even elite athletes. Thank you, Sage, for sharing your journey, lending your expertise to our runners, and helping others recognize the signs.

🏃‍♀️ Race day is almost here! The @nycmarathon takes place Sunday, November 2, and we couldn’t be prouder of the dedicated team of runners who will be pounding the pavement to support the National Blood Clot Alliance.

One of those runners is Aynslee Roberts of Idaho, who shared her story on @KTVB7 in Boise. She was training for her first marathon in 2023 when she was diagnosed with a pulmonary embolism triggered by hormonal contraception. As she recovered, she continued running.

As she prepares to run the biggest marathon in the world in less than two weeks, she’s keeping her “why” in mind — spreading awareness about blood clots.

“By sharing my story, I want to empower others to make well-informed choices about their health and well-being,” she said.

Aynslee, we’re so proud of you and we’re honored to have you on Team Stop the Clot.

Join us in wishing her—and the entire team—a fantastic race!

“My dad had suffered from multiple health disord

“My dad had suffered from multiple health disorders, including A-fib, asthma, high blood pressure, high cholesterol, and chronic cellulitis in both legs. I had been visiting him because he needed a lot of assistance.

One day in February 2024, I couldn’t reach him. I went over to his apartment to see what was wrong and he would not answer the door. So, my husband and I called for a wellness check. Once they were able to get through the door, he was gone and my life was forever changed. He was my rock, and someone I cared most about in life.

My dad was an avid Chicago White Sox fan. He was a man of God, loved playing cards, pool, bowling, and volunteering his time to helping others. Anything competitive got him going. He was a strong-willed, but loving man. He was never shy to share his opinions and definitely was not afraid to tell you when you were wrong.

He had an unique sense of humor, not matched by anyone I have ever met in my entire life. He loved to make others smile and laugh. No words can truly express how much he meant to me and nothing can replace the void that was left in his absence.

Take your health seriously, watch out for your family, and most importantly, enjoy every moment you can with your loved ones. You never know when it might be the last time you see them.”

❤️ A blood clot diagnosis can be devastating, and many patients struggle to move forward.

That’s why we created our New Patient Guide, a handbook for people who’ve been newly diagnosed with deep vein thrombosis (DVT), pulmonary embolism (PE), or cerebral venous sinus thrombosis (CVST).

Patients and their caregivers can get answers to common questions and access resources to help navigate life after this diagnosis.

❓ Question: Have you had thrombophilia testing?

❓ Question: Have you had thrombophilia testing?

About one-quarter to one-third of people who have had a blood clot test positive for thrombophilia, most often factor V Leiden or the prothrombin gene mutation.

⚠️ Important: Some tests can be distorted while you’re on blood thinners. Timing matters, so talk with your clinician about when to test and which tests are useful for you.

Why test? The value is case-by-case. Results don’t usually change short-term treatment, but may help guide long-term decisions (pregnancy planning or if your risk of recurrence is high).

🔉 Sound off in the comments about your experience with testing, and register for our November PEP Talk: Thrombophilia Testing While on Blood Thinners on Tuesday, Nov. 11 at 7 p.m. ET.

"In 2014, while in podiatry school, I went to the

"In 2014, while in podiatry school, I went to the student health center because I felt short or breath and was coughing up blood. The nurse practitioner diagnosed me with bronchitis.

Less than two weeks later, I learned the truth — I had a saddle pulmonary embolism, which means a large blood clot was blocking blood flow to both sides of my lungs. The clot was caused by birth control pills, along with other risk factors like recent travel and my weight.

I needed emergency treatment, including procedure called a mechanical thrombectomy to remove the clot from my leg and another procedure to dissolve the one in my lungs. I also had part of my lung damaged by the clot, called a pulmonary infarction.

I was on a blood thinner, rivaroxaban, for six months after this incident and I have done well since then. I delivered a healthy baby boy in 2023 and took daily blood thinning injections (enoxaparin) without any issues.

I was recently traveling and developed another blood clot in my leg (DVT). As a result, I will need to take blood thinners for life and I am okay with that. I am grateful to be alive.

As a physician, I am more aware of looking for the signs and symptoms of blood clots in my patients. If someone has symptoms that make me suspect a DVT, I don’t hesitate to order an ultrasound to check for it.

I enjoy looking at NBCA’s Instagram page and knowing I am not alone in this battle. There are a lot of people like me and I feel extremely grateful that I made it out alive.

My advice is to listen to your body. You know your body better than anyone else. If you feel the symptoms and are concerned, get checked out."

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.

❤️ 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. 🫶

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.
