Angina pectoris

Other names: Angina, Stable angina, Unstable angina


Angina is chest pain caused by reduced blood flow to the heart muscle, typically a symptom of Coronary artery disease. It can be described as squeezing, pressure, heaviness, tightness, or pain in the chest.



Angina is primarily caused by reduced blood flow to the heart muscle due to Coronary artery disease. Factors like physical exertion, emotional stress, cold temperatures, heavy meals, and smoking can trigger Angina.



The most severe complication of Angina is a Heart attack. Signs include chest pain lasting more than a few minutes, pain spreading to arms/back/jaw, shortness of breath, sweating, and nausea.


If experiencing sudden chest pain (unstable Angina), seek immediate medical help. Prepare for your appointment by noting symptoms, personal information, medications, and questions for your doctor.


Tests to diagnose Angina may include an Electrocardiogram (ECG), stress test, echocardiogram, nuclear stress test, Chest X-ray, blood tests, coronary angiography, and cardiac CT scan.


Treatment options for Angina include lifestyle changes (quitting smoking, weight management), medications (nitrates, aspirin), and medical procedures/surgery (angioplasty/stenting or bypass surgery).


Preventive measures for Angina include quitting smoking, controlling health conditions like high blood pressure and diabetes, following a healthy diet and exercise routine, maintaining a healthy weight, and reducing stress levels.
