The cardiac vein helps transport CO2-rich blood from the heart muscle to the right atrium, helping to continue the circulation process. When the cardiac vein is blocked, blood cannot circulate normally, increasing the risk of myocardial infarction and other complications.
Here are 5 unusual signs that warn that your heart veins may be blocked.
Prolonged chest pain
Cardiac vein blockage can cause persistent chest pain
One of the most obvious signs of a heart vein blockage is chest pain or tightness. The pain may appear as a feeling of pressure, squeezing, or burning in the chest area, especially in the middle or left side of the chest, according to the health website Healthline (USA).
Pain may radiate to the arms, neck, jaw or back. If the pain lasts longer than a few minutes and is not relieved by rest, it could be a warning sign of coronary artery disease or a serious blockage in the heart's veins.
Sudden shortness of breath
Blocked cardiac veins affect the heart's ability to pump blood, causing shortness of breath. You may feel short of breath with light activity, when lying down, or even at rest. If this feeling is accompanied by fatigue or lightheadedness, you may have heart failure. This is because blood cannot flow effectively through the cardiac veins.
Irregular heartbeat
An abnormally fast or slow heartbeat or atrial fibrillation can be a sign of a blockage in the heart's veins. When blood flow to the heart is unstable, the heart has to work harder to pump blood, leading to an arrhythmia.
The patient will notice a strong heartbeat, skipping beats or a feeling of nervousness, palpitations. If this symptom is accompanied by chest pain or difficulty breathing, go to the hospital immediately.
Swollen feet
Another effect of venous congestion is fluid buildup in the ankles and feet, causing swelling. This is a sign of congestive heart failure, when the heart cannot pump blood effectively, causing fluid to build up in the body. Swelling is often more noticeable at the end of the day or after sitting for long periods of time, and is often accompanied by a feeling of heaviness and discomfort in the legs.
Chronic fatigue
Cardiac vein obstruction also makes the patient often feel tired and exhausted without knowing the cause. Because when blood circulation is limited, the body will not receive enough oxygen and nutrients, making the body feel lethargic, reducing the ability to concentrate and easily losing strength when doing light exercise, according to Healthline.
