Angina is chest pain or pressure usually caused by not enough blood flow to the heart muscle. The degrees of pain vary from chest discomfort to being quite painful. Stable angina refers to having chest discomfort when doing some activities while have no or mild symptom at rest or after administration of sublingual nitroglycerin. Unstable angina is angina that changes or worsens, which may be a serious indicator of an impending heart attack. Another form of angina is called cardiac syndrome X. The most specific medicine to treat angina is nitroglycerin, which dialates the heart muscle arteries. Other drugs include beta blockers, and calcium channel blockers, Ivabradine, ACE inhibitors, and statins. Low-dose aspirin can also be used if the risk hemorrhagic stroke or gastrointestinal bleeding is low and the risk of myocardinal infarction is very high.
