Echocardiographic outcomes Of Prolonged Balloon Inflation During Stent Deployment Strategy In Primary Percutaneous Coronary Intervention For ST-Segment Elevation Myocardial Infarction

Background: ACS often serves as the initial clinical sign of CVD, and in STEMI cases, PPCI is the preferred strategy for reperfusion, provided it is administered promptly. Methods: The investigation enrolled 152 cases diagnosed with STEMI, all recommended for PPCI. These cases were allocated into two groups: Group I, the Prolonged Balloon Stent Inflation Group (PBSG), and Group II, the Conventional Deployment Stent Group (CDSG). Echocardiographic evaluations were conducted at baseline, immediately after PPCI on the first hospital day, and again at six months. Results: In primary outcomes, transient no-reflow occurred in 3 cases (3.9%) in Group I and 12 cases (15.7%) in Group II (P=0.03). More than 50% resolution of ST-segment elevation was noticed in 71 cases (93.4%) from Group I and 59 cases (77.6%) from Group II (P=0.011). Regarding secondary outcomes, both mean EF (P=0.002) and mean WMSI (P=0.001) showed significant improvements from baseline in both groups during follow-up, with a notable difference between the groups. In the LAD subgroup, there were similar improvements in mean EF (P<0.001) and mean WMSI (P<0.001), with a statistically significant difference between the two groups. Conclusion: Six months after PPCI, significant improvements in global and segmental LV wall motion were noted in STEMI cases, particularly in those who underwent PBS, as opposed to those who received CDS.
