Ndrepepa G, Cassese S, Xhepa E, et al. - Among patients with ST-segment elevation myocardial infarction (STEMI) (n = 1,369) undergoing primary percutaneous coronary intervention (PPCI), researchers examined the link between shock index and eight-year mortality post-STEMI. Three groups of patients were defined: a group with shock index in the first tertile including 458 patients (shock index, 0.21 to 0.52), a group with shock index in the second tertile including 457 patients (shock index > 0.52 to 0.67) and a group with shock index in the third tertile including 454 patients (shock index > 0.67 to 2.80). Findings revealed the link of elevated shock index with the risk of inhospital cardiogenic shock and death up to 8 years post-PPCI in STEMI patients. Results also indicated that the long-term adverse prognosis was almost completely driven by events within the first 30 days.
