Over half of the STEMI fatalities occur suddenly outside the hospital (VF). For patients who present to the hospital, the short-term mortality (30 days) is, on average, 4–5% for patients treated with primary PCI, 6–7% for patients treated with fibrinolytics, and ~11–12% for patients not treated with reperfusion therapy. This varies according to the risk criteria listed in Section 1.XI (Killip class and TIMI risk score), the ST-segment response to reperfusion therapy, and the coronary microvascular perfusion achieved with reperfusion therapy.

Afterward, the yearly mortality is 2–6% depending on the degree of LV dysfunction, the presence of HF, and the presence and extent of residual severe CAD.

The risk of sudden death is highest in the first 30 days after MI (1.2%), followed by a 1.2% sudden death risk per year.⁹⁸ The risk is higher in patients with HF or severe LV dysfunction (2.5–3%).

Note that NSTEMI has the same short- and long-term mortality as STEMI (but lower in-hospital mortality).¹⁷⁵
