^aP < 0.05,

^bP < 0.01 vs NR;

^dP < 0.01 vs primary coronary intervention (PCI);

^fP < 0.01 vs classe B;

^hP < 0.01 vs classe C. NR: Not send to reperfusion; TT: Transthoracic; AVB: Atrio-ventricular block requiring pacing; SVT: Sustained ventricular tachycardia; VF: Ventricular fibrillation; AF: Atrial fibrillation; PAT: Paroxysmal atrial tachycardia; R-MI: Reinfarction of the myocardium; UTVR: Urgent target vessel revascularization; MR/T: Myocardial rupture/tamponade; ARF: Acute renal failure; SSH: Sustained systemic hypotension (lasting < 12-24 h reversed with volume infusion and inotropic support); E-CS: Evolution to cardiogenic shock; +: Considered to be major cardiac complications.
