Clinical value of Selvester QRS score in evaluating myocardial scar load and midterm followup for patients with acute myocardial infarction after percutaneous coronary intervention
Abstract：Objective To explore the clinical value of Selvester QRS score in evaluating the myocardial scar load and mid-term follow-up for the patients with acute STsegment elevation myocardial infarction(STEMI) after emergency percutaneous coronary intervention(PCI), and to investigate the influencing factors of score variation at acute stage and during the follow-up. Methods Fifty-five acute STEMI patients who had undergone emergency PCI were consecutively enrolled in our study. Among them, 48 patients with follow-up completed were classified into general research group, anterior myocardial infarction group and inferior myocardial infarction group, and they were followed up separately 1 week, 1 month, 3 months and 6 months after PCI. Clinical data were collected and 18lead ECG was recorded. Selvester QRS score evaluation was synchronously performed. ResultsIn the anterior myocardial infarction group, Selvester QRS score gradually decreased 1 week，1 month and 3 months after PCI while the score did not significantly vary from 3 months to 6 months postoperatively.By making paired comparison among Selvester QRS scores at different time nodes of followup, we found there was no statistically significant difference in the inferior myocardial infarction group. The amplitude of score variation in the anterior myocardial infarction group was related to the opening time of culprit vessel(r=0.849, P=0.006). Conclusion Selvester QRS score proves to be effective for evaluating the myocardial scar load among the acute STEMI patients after emergency PCI. For patients with acute anterior myocardial infarction, it is suggested to make the score evaluation 3 months after PCI while no definite assessment time is required for the cases with acute inferior myocardial infarction.
