Are you in a high-risk category?
Although DVT can occur in almost anyone, certain people may be at higher risk of
developing a blood clot. If you fall into one of the following identified high-risk
categories, talk to your doctor about what you can do to protect yourself from DVT.
- Cancer patients undergoing surgical
procedures have at least twice the risk of postoperative DVT than non-cancer patients
undergoing similar procedures.18
- Cancer may cause clotting factors
in the blood to increase. Clotting factors may also be affected as a result of an
infection or injury to a blood vessel or following surgery.18
- Obese patients may not be able to
dissolve blood clots properly which may greatly increase
their risk of DVT after surgery.19
- Patients with an inherited clotting disorder
— e.g. Factor V Leiden are at an
increased risk for developing DVT. If both parents were affected, their
risk is at its highest.20
- In patients with prolonged immobility or no
mobility, blood flow can slow down and lead to
blood "pooling," or accumulating in the extremities, thereby
greatly increasing risk of DVT.
- In elderly patients, DVT is associated
with a 21% one-year mortality rate. While most
victims are 60 years of age or older, DVT
can strike anyone at risk.18
- Women taking oral contraceptives or hormone
replacement may be at increased risk of
- Patients with pulmonary embolism
may experience shortness of breath, an apprehensive feeling, chest pain, rapid pulse,
sweating or a bloody cough.1
- 1/3 of patients who have experienced
venous thromboembolism develop it again
within eight years of the initial event.
- Patients with congestive heart failure
have three times the risk for developing blood
- Patients who smoke have an increased risk of blood clots.21 Smoking reduces
the amount of oxygen carried in the blood, which damages vessel walls,
increasing the risk of blood clots.
- 50% of patients with deep-vein thrombosis
or pulmonary embolism have "silent" or minimal
