Stable angina is predictable and caused by similar precipitating factors each time; typically,it is exercise induced.Pain control is usually achieved by rest and by sublingual nitroglycerin within 5 minutes.Stable angina is the result of fixed lesions (blockages)of more than 75% of the coronary artery lumen and thus has a high correlation to coronary artery disease (CAD),not coronary spasm.
