Not unless you own a heart attack and enjoy disrupt to the heart muscle. When the heart muscle loses oxygenated blood, resembling when you hold a blocked coronary artery, the nouns where on earth it is not getting blood begin to die, specifically when your cardiac enzyme level will rise.

enzymatic audition of SGOT/AST is a concrete tryout for MI and Angina. CPK-MB is also advisable carrying out tests because it will rise 1-3 hours after myocardial injury.
SLDH (particularyl 1 and 2) may be used as deferred diagnosis of MI, it would rise 2-3 days after myocardial injury
Troponin 1 will also be the best diagnostic exam!
