As a medical professional with expertise in cardiology, I can provide you with information on the symptoms of insufficient oxygen supply to the heart, which is a condition known as ischemia. The symptoms can vary, but they often include: 1. Shortness of breath: This can occur when the heart is not receiving enough oxygen to function properly. 2. Fatigue: A general feeling of tiredness or weakness can be a sign that the heart is not getting the oxygen it needs. 3. Dizziness: Feeling lightheaded or faint can be a symptom of reduced oxygen flow to the heart. 4. Heart arrhythmia: This is an irregular heartbeat that can occur when the heart muscle is not getting enough oxygen. 5. Palpitations: These are sensations of the heart beating hard or fast, skipping a beat, or fluttering. 6. Angina: This is chest pain or discomfort that occurs when an area of your heart muscle doesn't get enough oxygen-rich blood. 7. More severe cases can lead to heart attacks, sudden cardiac arrest, congestive heart failure, or stroke. It's important to note that not everyone will experience all of these symptoms, and some may have milder or different symptoms altogether. If you suspect that you or someone else is experiencing symptoms of heart ischemia, it's crucial to seek medical attention immediately. read more >>
