New Study: Risk of Blood Clots More than 3-Fold Higher in Hospitalized Adults with COVID-19

July 21, 2021

An important new study conducted by NBCA MASAB Member Dr. Margaret Fang and colleagues is being published this month in CHEST. The study results show that hospitalized adults who have COVID-19 are more than 3 times as likely to develop a blood clot than adults who do not have COVID-19.

Maybe you found NBCA after a frightening ER visit.

Maybe you found NBCA after a frightening ER visit.

Maybe you learned the warning signs because someone you love didn’t have the chance to.

Or maybe you’re here because a single story opened your eyes to what blood clots can do — and what awareness can prevent.

At NBCA, we see every day how one moment of generosity can change someone’s life:

❤️ One donation fuels education for someone who’s scared and searching online at 2 a.m.

❤️ One resource gives a caregiver the words they need to advocate.

❤️ One story helps a person recognize symptoms and get treatment in time.

Your #GivingTuesday support strengthens that ripple — one person, one family, one life at a time.

Every gift — $10, $25, $50, or any amount — helps save lives.

Thank you for being part of this life-saving ripple. 💛

🏈 It’s game day! 🏈

Tonight on Monday Night Football, @Patriots long snapper @julian.ashby takes the field promoting the National Blood Clot Alliance and blood clot awareness through My Cause My Cleats — a tribute to former @paladinfootball teammate Bryce Stanfield, who died suddenly from a blood clot in 2024.

Bryce’s mother, @teristanfield, shared how much this moment means to their family: “If sharing his story helps one person recognize a warning sign or get help sooner, then his light is still shining, and his life is still making a difference.”

🎉 We’re proud to share that the National Bloo

🎉 We’re proud to share that the National Blood Clot Alliance (NBCA) has been selected for an Oral Presentation at this year’s American Society of Hematology Annual Meeting — an extremely competitive distinction awarded to only a small percentage of abstract submissions each year, and even fewer nonprofit organizations.

Our presentation next week will highlight insights from the B.L.A.C.K. (Black Lives Advocating for Clot Knowledge) Church Bus Tour, a first-of-its-kind community-based initiative created to address critical health disparities by partnering with Black faith communities across the southeastern United States.

Post-event surveys showed significant increases in knowledge about blood clot risks, symptoms, and treatment — and 100% of attendees said they planned to share what they learned with others. These outcomes demonstrate the power of culturally tailored, community-driven outreach to close gaps in blood clot awareness and save lives.

We’re honored to bring this work to the clinical community and to elevate how community partnerships can meaningfully address blood clot health disparities.

🏈 Countdown to Monday Night Football 🏈 TONI

“This May, I tore my calf muscle playing soccer.

“This May, I tore my calf muscle playing soccer. It was the same injury I had only three months earlier, so I thought I knew what to expect. Three days later, I had a massage and then left for Cuba that evening on a three-hour flight.

My calf was sore and I had bought a calf sleeve to support me it while walking. The pain in my calf was terrible, especially when I woke up in the night to go to the washroom, or waking up in the morning. It lessened slightly with walking.

A few days into my trip, I developed a rash all down my right shin on my injured leg and the calf was mildly swollen. I thought it could be heat rash as it was very hot that week and I had been wearing a support sleeve on my leg. I felt uncomfortable since it was on my injured leg and was driven by taxi to a nearby clinic at 3 a.m.

I explained the injury to the doctor and that I had been wearing a support sleeve for my calf. She touched my calf and said it was heat rash. She recommended keeping it cool and elevated. I believed the doctor and stayed in my air conditioned room for the remainder on my trip with my leg elevated.

I got home and my ankle was so swollen. I went to urgent care the next morning where I explained everything to the doctor. He sent me for an ultrasound, which found a DVT above the back of my right knee. He said he suspected I had a blood clot just by looking at my leg. I was overwhelmed and cried a bunch that weekend. I was on apixaban for three months and my next ultrasound came back clear, clot fully resolved.

I'm a little anxious of random feelings in my legs. But after my calf injury healed, I'm prioritizing exercise again and being smart while I travel. I went to Portugal while on thinners. I wore compression socks, moved on the plane and booked aisle seats. I was told I’m not someone who is especially prone to getting clots, which is reassuring, but the worry is still there.

Blood clots symptoms can mimic so many other things. So, be careful.”

💊Taking a blood thinner and have Medicare?

You may qualify for an option to help manage your prescription costs.

The Medicare Prescription Payment Plan (MPPP), first introduced in 2025, will make it easier for individuals with Part D drug coverage to afford important medications — including anticoagulants — by letting you spread your out-of-pocket drug costs into monthly, interest-free payments instead of paying everything at once.

This can help if you:

💊 Take lifelong or high-cost blood thinner medications

💰 Struggle to afford large pharmacy bills up front

🗓️ Prefer smaller, predictable monthly payments

Participation is optional, and you can enroll anytime, but reviewing your coverage and eligibility now during open enrollment ensures you’re prepared.

“In June 2024, shortly after turning 30, I was d

“In June 2024, shortly after turning 30, I was diagnosed with an unprovoked DVT in my lower left leg. The diagnosis and the sudden need to start blood thinners felt like a death sentence. I was terrified and didn't know where to turn.

Once the clot was discovered, I was started on apixaban immediately and told to follow up in a few months for genetic testing to uncover why the clot had formed in the first place. Estrogen-based birth control was my only known risk factor.

I eventually found an excellent team of specialists, a vascular doctor, primary care physician, hematologist, and rheumatologist, who worked collaboratively to order the appropriate genetic tests after six months on apixaban.

In May 2025, nearly a year after the clot was first identified, I finally received a diagnosis: triple positive antiphospholipid syndrome (APS) and chronic venous insufficiency (CVI).

From there, I transitioned from apixaban to warfarin, using an injectable medication called enoxaparin to bridge between the two. It took months for my body to stabilize within a therapeutic range, and I’m still learning about warfarin’s sensitivities and how to manage my INR — a standardized measure of how long it takes for your blood to clot, which is used to ensure warfarin stays at a safe and effective level.

This has been the most unexpected and discouraging journey of my life, but I continue to challenge myself, advocate for myself, and encourage others to do the same.

I’m still adjusting to this new reality of bloodwork every two weeks, wearing compression socks every day, INR monitoring, routine ultrasounds, and the understanding that lifelong management will be part of my care.

My goal as a young woman living with vascular and blood disorders is to raise awareness and promote healthy blood flow habits, such as leg elevation and wearing compression socks. There is simply not enough information or visibility for young women with autoimmune and clotting disorders, especially those with APS or CVI."

Happy Thanksgiving! 💛 Today is all about gratitude, connection, and the people we love. It’s also National Family Health History Day — a reminder that one of the most meaningful conversations you can have is about your family’s health.

Blood clots can be linked not only to surgery, injury, pregnancy, or long travel, but also to hereditary conditions you may not know about. Sharing your family’s health story can help protect the people you love most.

🎙️ New Episode Alert! 🎙️

Season 3, Episode 3 of Taking a Breath: A Stop the Clot podcast is now available on all major podcast platforms.

In this episode, listeners hear from Chris Gailus, anchor of News Hour on Global BC Television in Vancouver. He describes how he experienced leg swelling after a morning run and figured it was a pulled muscle.

About a week later, he felt a sharp pain in his side along with shortness of breath.

The ER sent him home, so he waited a few days until a scheduled checkup with his doctor, who recognized the signs of a pulmonary embolism.

“I’m thankful to him,” Chris said, his voice filled with emotion. “I believe he saved my life.”

During Thanksgiving week, we’re thinking about the people whose awareness, instincts, and advocacy save lives every day — including clinicians like the one who recognized Chris’s PE.

Thank you, Chris, for sharing your story and helping raise awareness. 👉 Listen to his journey on our website or wherever you get your podcasts: Link in bio.

⏰ #GivingTuesday is just one week away on December 2!

Blood clots don’t wait, and neither can we. Every few minutes, someone in the U.S. is hospitalized or loses their life to a preventable blood clot.

Behind every survivor is a ripple — a clinician who recognized the signs, a family member who urged them to seek care, a friend who shared a resource, or a stranger’s story that inspired them to act. Your support helps create those ripples before someone even knows they’ll need them.

This Giving Tuesday, your action can spark the next ripple.

Your support helps the National Blood Clot Alliance raise awareness, equip clinicians, fund patient education, and empower people to recognize the signs before it’s too late.

🔗 Here are four ways to join NBCA this Giving Tuesday (the link in our bio has more info!)

“On December 11, 2024, I went to the emergency r

“On December 11, 2024, I went to the emergency room because my entire right arm was swollen. My father told me not to go since I wasn’t in pain and already had a doctor’s appointment scheduled for the next day, but something told me to get it checked out. I honestly thought it was just a pinched nerve — nothing serious.

When the ER doctor came in and told me I was in a life-or-death situation after finding a blood clot, or deep vein thrombosis (DVT) in my arm, my whole world stopped. They prepared to transfer me for emergency surgery but later decided instead to start me on blood thinners and send me home. I didn’t realize at the time that my life was still in danger.

In the early morning hours of December 12, around 3 a.m., I woke up gasping for air. I couldn’t breathe. My heart was pounding out of my chest. My consciousness began to fade, and my whole body was tingling and numb. When I touched my left arm, I couldn’t feel my own touch — the sensation was completely gone.

I was rushed to the hospital and woke up the next day, Friday, December 13, after 12 hours in the ER. The doctors told me I was lucky to be alive — I had suffered a pulmonary embolism.

After my PE, I struggled to understand how this could have happened to me. It was labeled as unprovoked, which only made me more determined to find answers. For months, I shared my story, changed doctors, and kept searching.

My first hematologist told me there was nothing they could do to figure out why I had a blood clot and to seek psychological help.

About nine months later, after switching hematologists and hospitals, I finally learned the cause: venous thoracic outlet syndrome (VTOS). My right first rib was severely compressing my subclavian vein — the same area where my clot had formed back in December.

On October 22, 2025, I underwent surgery to remove my first rib. Without it, I faced a high risk of another DVT or pulmonary embolism.

I believe God saved my life for a reason, and I’m grateful every day to still be here. My message to others: never stop advocating for yourself — your life may depend on it.”
