NSTEMI occurs by developing a complete occlusion of a minor coronary artery or a partial occlusion of a major coronary artery previously affected by atherosclerosis. This causes a partial thickness damage of heart muscle.
There is no difference between NSTEMI and STEMI in clinical presentation. In both cases, patients usually present with similar type of symptoms such as chest pain, nausea, vomiting, sweating, breathing difficulty.

Cardiac markers including CK-MB (creatine kinase myocardial band), troponin I and troponin T, all elevate both in cases. But the elevation of these markers is often mild in NSTEMI compared with STEMI.
