Association of neutrophil-to-prognostic nutritional index ratio with long-term mortality in acute myocardial infarction from Chinese and US cohorts (opens in new tab)

BackgroundDespite advancements in reperfusion strategies, patients with acute myocardial infarction (AMI) face significant risks of long-term mortality. Systemic inflammation and nutritional/immune depletion synergistically impact prognosis. This study investigated the prognostic value of the neutrophil count to prognostic nutritional index ratio (NPNR)—a novel composite index reflecting inflammatory burden and nutritional reserves—in AMI patients.MethodsThis dual-cohort study included 2020 p...
