Abstract Objective To study the relationship between pulse oxygen saturation (SpO₂) during primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) and its clinical efficacy and prognostic value. Methods We studied 132 STEMI patients for whom pulse oxygen saturation was monitored continuously during primary PCI. According to the pS02, the patients were divided into the observation group(n=64, SpO₂＜90%) and the control group (n=68, SpO₂≥90%). We observed the number of the stenotic vessls, left ventricular end-systolic volume(LVESV), left ventricular end-diastolic volume(LVEDV)and Left ventricular ejection fraction (LVEF) 4 weeks after PCI, and also analyzed the major adverse cardiac events(MACE) and six-minute walk test between the hospitalization period and 6 months after PCI. Results The number of the stenotic vessls in the observation group was greater than in the observation group[(1.9±0.9) vs (1.2±0.8), P<0.05], and the percentage of infarct-related artery in the left anterior descending artery was also higher (62.6% vs 41.2%, P<0.05). The diameters of LVESV, LVEDV were larger, and the LVEF was lower than the control group. The incidence of MACE between the hospitalization period and 6 months after PCI in the observation group was higher, while shorter in the six-minute walk test than the control group. Conclusions The pSO₂ during primary PCI with STEMI is a reliable index in evaluating the clinical efficacy and prognostic value.
