Stenocardia

Form of coronary heart disease characterized by short-term chest pain (from a few seconds to 20 minutes or more), causing a sensation of pressure, stretching, squeezing in the chest. This pain usually starts behind the breastbone (in the central chest area), less commonly it is felt slightly to the left of the breastbone. The pain can spread: most commonly it radiates to the arms (especially the left one), as well as to the lower jaw, neck, chin, pit of the stomach (towards the stomach). Physical exertion, tension, cold, and heavy meals can trigger angina chest pain. Nitroglycerin can be used to stop an attack.

An electrocardiogram may reveal signs of myocardial ischemia:

Stable angina – attacks occur after physical exertion or emotional stress.
Unstable angina – most often a pre-infarction state.
Resting angina – occurs at night and is considered the initial phase of a myocardial infarction.
