New Research Ties Rare Inflammatory Disease to Increased Risk of Cardiovascular Disease
June 24, 2022 (Vancouver) – Researchers at Arthritis Research Canada have found that people with a rare inflammatory disease known as granulomatosis with polyangiitis (GPA) have an increased risk of serious, life-threatening blood clots.
Our research finds that people with GPA have a 190% increased risk of the blood clot condition venous thromboembolism (VTE). Researchers looked at the two categories of VTE: pulmonary embolism (PE), wherein the blood clot travels to the lungs, and deep vein thrombosis (DVT), wherein the blood clot forms in the deep veins of the leg, pelvis, or arm. People with GPA were found to have a 370% increased risk of PE, but no increased risk of DVT.
“These blood-clotting conditions are potentially fatal for patients, but with the correct intervention, they can be prevented,” said Dr. Antonio Aviña-Zubieta, a rheumatologist and senior scientist at Arthritis Research Canada.
Granulomatosis with polyangiitis (GPA), is characterized by inflammation of the blood vessels, which can restrict blood flow, impact organ function, and even damage vital organs like kidneys or lungs. Other complications include vision or hearing loss, heart disease, and stroke. Luckily, this complex disease is treatable with corticosteroids and other drugs that suppress the immune system to control inflammation.
Previous studies have also tied this disease to an increased risk of serious blood clots soon after diagnosis. One UK-based study found that 31 per cent of people with the condition developed serious blood clots within a month of receiving a diagnosis.
“These findings have the potential to save lives,” Aviña-Zubieta said. “Clinicians need to be aware that patients who have GPA are more likely to experience serious blood clots, especially within the first year after a GPA diagnosis.”
It is estimated that GPA affects 3 out of every 100,000 people. While this rare disease can occur at any age, onset is typically between 40 and 65 years of age. This research calls for increased vigilance and preventative monitoring of people living with granulomatosis with polyangiitis. Further study is needed to investigate prevention treatments.

Cardiovascular disease is the leading cause of death in people with arthritis. Patients are at the highest risk for heart attacks, strokes and blood clots in the legs and lungs in the first year after diagnosis, when inflammation is also at its peak.
