Symptoms of arterial thrombosis
Arterial thrombosis can lead to serious and life-threatening complications based on where the blood clot forms. Here is a summary of symptoms for different conditions related to arterial thrombosis:
Heart Attack
A blood clot blocking an artery supplying blood to the heart muscle can result in a heart attack. Symptoms include:
- Crushing central chest pain or mild chest discomfort
- Shortness of breath
- A clammy, sweaty, and pale complexion
- Dizziness
- Nausea and vomiting
If you suspect a heart attack, call emergency services (999) immediately.
Stroke
When a clot blocks an artery supplying blood to the brain, it may cause a stroke. Symptoms include:
- Sudden numbness or weakness, especially on one side of the body, ranging from weakness in a hand to paralysis
- Weakness or drooping in the face
- Dizziness
- Difficulty speaking or understanding speech
- Loss of balance and coordination
- Difficulty swallowing
If a stroke is suspected, call emergency services (999) without delay.
Peripheral Vascular Disease (PVD)
Clots in the legs or narrowing of leg arteries may cause symptoms such as:
- Increased susceptibility to blood clots
- Pain during exercise, typically in the lower legs
- Pain affecting one leg more than the other
- Pale, cold skin, and numbness in one leg
- In more severe cases, PVD can cause impotence or discoloration of one leg, which requires immediate medical attention.
If any of these symptoms arise, particularly sudden and severe changes, seek immediate medical assistance by contacting emergency services or your GP.
Causes of arterial thrombosis
Diagnosing arterial thrombosis
Diagnosing arterial thrombosis involves various tests and methods depending on the condition triggered by the blood clot. Here are some common diagnostic tools used:
Electrocardiogram (ECG)
For suspected cases of unstable angina and heart attacks, an ECG is commonly used. This test measures the electrical activity of the heart each time it beats, and the results are displayed on paper. It helps doctors identify how well the heart is functioning and whether there are areas that aren’t receiving adequate blood supply, as would occur during a heart attack.
Blood Tests
A blood test is often used to measure levels of a protein called troponin, which is released into the bloodstream when the heart muscle is damaged, such as during a heart attack. Elevated troponin levels can confirm that a heart attack has occurred or is in progress.
Scans
- Computed Tomography (CT) Scan: Used to create detailed images of the body and is especially useful for diagnosing suspected cases of stroke. A CT scan can identify if the stroke was caused by a blood clot blocking blood flow to the brain.
- Magnetic Resonance Imaging (MRI) Scan: An MRI uses powerful magnets and radio waves to produce detailed images of the brain or other parts of the body. It is particularly helpful for diagnosing strokes, as it provides a clearer view of the soft tissues and can detect areas of the brain affected by a clot.
These tests help doctors assess the severity and location of arterial thrombosis, guiding appropriate treatment options to restore blood flow and minimize damage.
Treating arterial thrombosis
Preventing arterial thrombosis
Preventing arterial thrombosis focuses on reducing the risk factors associated with blood clots in the arteries and maintaining a healthy lifestyle. Although it is not always possible to prevent blood clots entirely, there are effective measures that can lower the risk significantly.
Medication
If you have experienced a blood clot in an artery before, your doctor may prescribe medication to help prevent it from happening again. These medications may include:
- Statins: Used to lower cholesterol levels in the blood, which helps reduce the buildup of fatty deposits in the arteries.
- Anticoagulant Medicines: Such as warfarin, which helps to thin the blood and prevent clots from forming.
- Antiplatelet Medicines: These include low-dose aspirin and other medications that help prevent blood cells called platelets from sticking together and forming clots.
- Angiotensin-Converting Enzyme (ACE) Inhibitors: Often used to treat high blood pressure, which is a key risk factor for arterial thrombosis.
Lifestyle Changes
In addition to taking medication, adopting a healthy lifestyle is crucial for reducing the risk of arterial thrombosis. Most cases are linked with atherosclerosis, where fatty deposits build up and narrow the arteries, increasing the risk of blood clots, heart attacks, and strokes. Making positive lifestyle changes can help reduce these risks:
- Stop Smoking: Smoking damages blood vessels and promotes the buildup of fatty deposits. Quitting smoking is one of the most effective ways to reduce your risk.
- Limit Alcohol Intake: Reduce alcohol consumption to within recommended limits to support cardiovascular health.
- Reduce Salt Intake: Reducing the amount of salt in your diet can help lower blood pressure, a major risk factor for arterial thrombosis.
- Healthy Diet: Aim to eat at least five portions of fruit and vegetables per day and two portions of fish per week, with one of these being oily fish such as salmon or mackerel, which is rich in omega-3 fatty acids.
- Exercise Regularly: Engage in at least 30 minutes of moderate exercise, such as walking or cycling, at least five times a week to improve cardiovascular health and maintain a healthy weight.
By following these lifestyle measures and adhering to any prescribed medication, you can significantly lower the risk of arterial thrombosis and its associated complications. Regular check-ups with a healthcare professional can further ensure that you are managing any risk factors effectively.
