what is the difference between MI and angina (list descriptions of MI) |

Definition
pain lasts a matter of minutes. Pain relieved by nitroglycerin and/or rest. Cell death (infarction) does not occur. If chronic stable angina, it is evoked by increased myocardial demand at established level of onset. If unstable angina, it's not associated with demand and is unpredictable |
