As a medical professional, I can provide you with information on the signs and symptoms of a heart blockage, which is a serious condition that requires immediate attention. Heart blockages are often caused by coronary artery disease (CAD), where the arteries that supply blood to the heart muscle become narrowed or blocked due to a buildup of plaque. **Signs and symptoms of a heart blockage may include:** 1. Chest pain or discomfort: This can feel like pressure, squeezing, fullness, or pain in the center of the chest and can last for a few minutes or come and go. 2. Shortness of breath: This can occur with or without chest pain and may worsen with activity. 3. Palpitations: These are irregular heartbeats, skipped beats, or a "flip-flop" feeling in your chest. 4. A faster heartbeat: This can occur as the heart tries to compensate for the reduced blood flow. 5. Weakness or dizziness: Feeling lightheaded or weak can be a sign of reduced blood flow to the brain. 6. Nausea: An upset stomach can sometimes accompany heart blockage symptoms. 7. Sweating: Breaking out in a cold sweat can be a response to the stress the heart is under. 8. Pain or discomfort in other areas: This can include pain in the arms, neck, jaw, shoulder, or back. It's important to note that not everyone will experience all of these symptoms, and some people may have a heart attack without any chest pain. If you or someone else is experiencing any of these symptoms, especially if they are severe, persistent, or accompanied by other symptoms, it's crucial to seek emergency medical help immediately. read more >>
