A BLOOD CLOT IN YOUR LEG COULD LEAD TO A RIGHT HEART FAILURE
The human body is a complex machine with numerous veins, tissues, muscles, and bones coming together to give it shape and structure. Several vital organs like heart and lungs ensure the functioning of our body and it is quite impossible to know what all goes inside these organs unless their activity is affected especially when something like a blood clot occurs. Blood clots can be particularly life-threatening when happening in the most crucial human organ, the heart.
A blood clot is a lump of blood that takes a gel-like or semi-solid state. While clotting of blood becomes an important process that prevents the person from losing blood in instances of cuts or injury; it can be severely dangerous when a clot forms inside the veins and does not always dissolve on its own.
A blood clot generally presents with swelling, pain, redness of skin or discoloration, higher heartbeat, coughing or breathing issues depending on where the clot has developed.
The human circulatory system comprises vessels called arteries (vessels which carry blood from the heart) arteries and veins (vessels which carry blood away from the heart) that are responsible for blood transportation through the body. Blood clots can form in arteries or even in the veins.
A blood clot forming in an artery is called an arterial clot. It is accompanied by severe pain, paralysis of parts of the body, a heart attack or a stroke and requires immediate emergency treatment.
Another type of blood clot is called venous clot when a clot occurs in a vein. Such clots generally build up slowly over time but can still be life-threatening. When a clot occurs in one of the major veins deep inside the body, it is called deep vein thrombosis (DVT). It usually occurs in the lower leg.
A DVT can lead to pulmonary embolism (PE). PE usually occurs when a blood clot formed in the leg travels upwards the right heart towards and eventually blocks a blood vessel supplying the lungs (pulmonary arteries). When a blood vessel is blocked, it reduces the levels of oxygen in the blood. This can severely damage the lungs, the heart, other organs and even cause right heart failure.
Those who are affected by DVT, are more at the risk of PE and must get diagnosed timely and properly. DVT and PE are forms of Venous thromboembolism (VTE) which refers to the formation of blood clots in the veins.
Some of the symptoms to be looked out for include:
· Heaviness, tightness, severe pressure or pain in the chest which might worsen with a deep breath
· Paced up heartbeat
· Lightheadedness or fainting
· Sudden cough or coughing up blood
· Excess of sweating
· Difficulty in breathing
· Shortness of breath
· Discomfort in jaws, neck, arms
Some of these symptoms are similar to a heart attack symptoms. A heart attack occurs when a blood clot blocks the blood flow in the heart causing a cardiac muscle to die. However, when the blood clot is not of considerable size, it may not show any of the above major symptoms but could still be dangerous and therefore diagnosis and awareness about your condition is key.
A person is likely to get a blood clot in leg veins after prolonged immobility like bone breaks or a muscle is pulled badly such as by severe trauma like in a car accident. Sometimes a clot can happen without a necessary reason too and the person might not even realize. Other possibilities include:
· While one is recovering from a surgery or had an extremely long sitting in a flight or a wheelchair over many hours without any movement
· Obese person, someone with diabetes or high cholesterol
· Hip or knee replacement
· Cancer or cancer treatments
· Usage of birth control methods that contain estrogen such as the pill, patch or ring
· Pregnancy; the six weeks after the baby’s birth
· A family history of blood clots
TREATING A CLOT IN THE HEART
Usually, medication can help in treating the clot. The doctor is likely to use blood-thinning medication or anticoagulants to limit the growth of the blood clot. Based on the size of the blood clot as well as its location, further treatment or therapy could be required. Medications could still be advised to prevent any complications further. In rare cases, however, medicines are not sufficient to remove the clot and a surgical procedure might be required. Surgery can be done by inserting a catheter into vein, mostly in the leg, until it reaches the blood clot. The surgeon can then break up the clot and remove it.
Blood clots can be prevented and better treated if a person is aware of the risk and recognizes the signs, reaching out for timely medical help. Maintaining a healthy weight along with a healthy lifestyle habits that have sufficient physical activity and not involve smoking, also reduces the chances of developing a blood clot.
