As a medical professional, I can tell you that a blocked artery, also known as peripheral artery disease (PAD) when it occurs in the limbs, or coronary artery disease (CAD) when it affects the heart, can lead to a variety of symptoms. It's important to recognize these signs as they may indicate a serious health condition that requires medical attention. Here are some of the symptoms you might experience if an artery is significantly blocked, such as by 70% or more: 1. Chest pain: This can occur during physical activity and may be relieved by rest. It's often described as a feeling of pressure, squeezing, or fullness in the chest. 2. Shortness of breath: You might find yourself out of breath more easily than usual, which can be a sign that the heart isn't getting enough oxygen. 3. Heart palpitations: These are feelings of your heart skipping a beat, fluttering, or beating too hard or too fast. 4. Weakness or dizziness: A lack of blood flow can cause these symptoms, particularly during or after physical activity. 5. Nausea: This can sometimes accompany chest pain and may be a sign of a more serious heart condition. 6. Sweating: Unexplained sweating, especially with chest pain, can be a sign of a blocked artery. If you suspect that you have a blocked artery, it's crucial to seek medical help immediately. Early diagnosis and treatment can prevent complications and improve outcomes. read more >>
