Angina pectoris
Angina pectoris commonly known as angina. Angina is a symptom of coronary artery disease. Angina often occurs when the heart muscle itself needs more blood than it is getting. it is characterized by a feeling of pressure and suffocation just behind the breastbone. Angina can accompany or be a precursor of a heart attack. Angina can much less often be caused by valve disease, especially aortic stenosis,hypertrophic obstructive cardiomyopathy, hypertensive heart disease, arrhythmias, arteritis and anaemia. Angina pectoris occurs when cardiac workload and resultant myocardial O 2 demand exceed the ability of coronary arteries to supply an adequate amount of oxygenated blood, as can occur when the arteries are narrowed.
