1 Values are expressed as absolute values and percentages, respectively. All p values refer to between-group comparisons based on Fisher’s exact test. ns, nonsignificant; hs-cTnI, high-sensitivity cardiac troponin I; LVEF, left ventricular ejection fraction; NTproBNP, N-terminal pro-B-type natriuretic peptide.
FIGURE 2.
Distribution of treated culprit lesions in patients with STEMI and NSTEMI. Left main artery involvement was significantly higher in NSTEMI patients (47.4% vs. 2.04%; p < 0.0001), whereas RCA lesions were more frequently treated in STEMI (40.81% vs. 7.4%; p < 0.0001). No statistically significant differences were observed for LAD or CX involvement.

FIGURE 3.
Distribution of hemodynamic instability in patients with STEMI compared to those with NSTEMI. The chart illustrates a significantly higher occurrence of hemodynamic instability in patients with NSTEMI (10.93%) compared to those with STEMI (0.18%), with statistical significance noted (p = 0.005).
FIGURE 4.
Comparison of ventricular arrhythmias between the two groups. The analysis showed no statistically significant difference in the incidence of hemodynamic instability between patients with NSTEMI and STEMI.
