Q. Common causes related with angina pectoris?
• The usual cause of angina is the narrowing of the major coronary artery due to atherosclerosis.
• Systemic hypertension increases myocardial demand and if the supply of blood to the heart muscles is less, it can cause angina.
• Heart disease: In late stages of aortic stenosis (narrowing of aorta) it can precipitate an anginal attack.
• Anaemia: The heart gets less oxygen due to lack of haemoglobin in anaemia.
