As a medical professional with expertise in cardiology, I can provide you with information on the symptoms of blocked heart arteries, which is a condition medically known as coronary artery disease (CAD). Blocked heart arteries can lead to a reduction in blood flow to the heart muscle, which can cause a range of symptoms. Here are some common symptoms associated with CAD: 1. Chest pain or discomfort, often described as a feeling of pressure, fullness, or pain in the chest. This is known as angina and is typically triggered by physical exertion or emotional stress. 2. Shortness of breath, which may occur with physical activity or at rest. 3. Fatigue, especially during physical activities that were previously manageable. 4. Irregular heartbeats or palpitations. 5. Nausea or indigestion, which can sometimes be mistaken for heartburn or other digestive issues. 6. Dizziness or lightheadedness, which may be accompanied by sweating. 7. Pain in other areas of the upper body, such as the arms, neck, jaw, shoulder, or back. It's important to note that not everyone with blocked heart arteries experiences the same symptoms, and the severity can vary widely. Some people may have no symptoms at all, while others may have more severe and sudden symptoms like a heart attack. If you suspect you have blocked heart arteries, it's crucial to seek medical attention immediately. A healthcare provider can perform a physical examination and various tests, such as an electrocardiogram (ECG), blood tests, stress test, or imaging studies, to diagnose and treat the condition. read more >>
