The pain associated with angina is described as a crushing or squeezing discomfort. This pain can last from two to fifteen minutes. Those with unstable angina are at high risk for heart attack. Angina is treated with rest to decrease the heart's workload, and nitroglycerin tablets for pain. It may also occur in those with previous symptoms of heart disease.
Sudden death can also occur during a heart attack.
When sudden cardiac death occurs, the heart stops beating and breathing ceases. Victims of sudden death are often found to have significant coronary heart disease, even when no previous symptoms were present. Used under License.
