Coronary ischemia
Coronary Ischemia
Coronary ischemia (pronounced: kuh-ROH-nuh-ree is-KEE-mee-uh) is a medical condition that occurs when blood flow to the heart muscle (Myocardium) is obstructed, usually by a sudden blockage in the Coronary arteries. This can lead to a heart attack (Myocardial infarction) if not treated promptly.
Etymology
The term "Coronary" is derived from the Latin word 'corona', meaning 'crown', referring to the way the coronary arteries encircle the heart. "Ischemia" is derived from the Greek words 'ischo', meaning 'to hold back', and 'haima', meaning 'blood'. Thus, coronary ischemia literally means 'holding back blood to the heart'.
Symptoms
Symptoms of coronary ischemia can include chest pain (Angina), shortness of breath, fatigue, and irregular heartbeat (Arrhythmia). However, some people may not experience any symptoms, a condition known as silent ischemia.
Diagnosis
Diagnosis of coronary ischemia typically involves a physical examination, medical history, and various tests such as an electrocardiogram (ECG), stress test, and coronary angiogram.
Treatment
Treatment for coronary ischemia aims to restore blood flow to the heart. This can involve medications, lifestyle changes, and in severe cases, surgery such as coronary artery bypass grafting (CABG) or angioplasty.
