Does having ANCA-associated vasculitis increase my risk of heart problems and death?
ANCA-associated vasculitis is a condition where the immune system attacks blood vessels. Research shows that having this disease puts you at a much higher risk for major heart problems and dying sooner than the general population. The leading causes of death after the first year are heart disease, infections, and cancer, rather than the vasculitis itself 2.
What the research says
Studies confirm that patients with ANCA-associated vasculitis face a significantly higher risk of major cardiovascular events like heart attacks and strokes. A large review found that these patients are 49% more likely to have a heart attack and 43% more likely to have a stroke compared to those without the disease 6. They are also at a much higher risk for dangerous blood clots, including deep vein thrombosis and pulmonary embolism 6.
The risk of death is also elevated. One study found that the risk of dying was more than three times higher for patients with granulomatosis with polyangiitis or microscopic polyangiitis compared to matched controls without the disease 2. Another analysis showed that cardiovascular disease is a leading cause of death in subsequent years after diagnosis 2. This increased risk of dying from heart causes is linked to accelerated hardening of the arteries, known as atherosclerosis, which happens more frequently in these patients 4.
Researchers have found that the specific type of vasculitis matters. Patients with myeloperoxidase-associated vasculitis (MPO-AAV) show distinct changes in their immune cells that drive inflammation and blood clotting, even when the disease is in remission 5. Additionally, patients often develop high blood pressure, diabetes, and high cholesterol, which further increase heart risk 4.
What to ask your doctor
- How does my specific type of ANCA-associated vasculitis affect my heart risk?
- What steps can I take to manage my blood pressure, cholesterol, and diabetes to protect my heart?
- Should I be on medication to prevent blood clots given my condition?
- How often should I have my cardiovascular risk factors checked?
- What signs of heart trouble or blood clots should I watch for and report immediately?
