Résumé
Background: ST-elevation myocardial infarction (STEMI) represents the life-threatening manifestation of atherosclerosis, a chronic inflammatory disease of arterial wall, and is associated with high rate of morbidity and mortality. Thus, inflammatory biomarkers may be useful in identifying high inflammatory burden patients who may benefit from tailored high-intensity secondary prevention therapy. Purpose: We therefore assessed the relationship between the systemic immune-inflammation index (SII) and CV outcomesamong 1144 all-comers patients admitted to four Swiss University Hospital for STEMI and enrolled in the prospective multicenter SPUM registry cohort I (NCT 01000701). Methods: SII was calculated as platelet counts x neutrophil counts / lymphocyte counts. Patients were subdivided into three groups according to SII tertiles. The composite primary endpoint was major adverse cardiac and cerebrovascular events (MACCE: stroke, myocardial infarction, CV death). Adjusted Cox proportional hazards regression models were implemented to determine the risk associated with SII and outcomes. Results: Out of 1144 STEMI patients, 912 patients (79,7%) had available for SII. Patients within the highest tertile were slightly more frequently male (23.0 vs 22.0%, p=0.05), with higher plasma values of neutrophils (11.4±2.4 vs 6.5±3.7 G/l, p<0.001), platelets (275.3±97.5 vs 202.5±51.6 G/l, p<0.001) and lower levels of lymphocytes (1.0±0.6 vs 2.1±1.1 G/l, p<0.001) and LVEF (46.4±11.5% vs 50.4±10.3%, p<0.001) (Fig. 1A). At 1 year, these patients presented the highest rate of all-cause mortality (7.2% vs 2.6%, p=0.02) and MACCE (8.2% vs 3.3, p=0.03). This enhanced risk persisted for all-cause mortality and MACCE, after adjustment for age, sex, ace-inhibitors and statin therapy (Adj. HR 2.85, 95% CI 1.30-6.70, p=0.03 and Adj. HR 2.63, 95% CI 1.25-5.55, p=0.03, respectively, Fig. 1B). Conclusions: Among a real-world cohort of STEMI-patients, SII highlights the highest inflammatory risk phenotype, being associated with significant increased rates of MACCE and all-cause of death. These observations might help clinicians to furtherly identify patients who may derive the greatest benefit from tailored more intense secondary prevention therapies including inflammatory modulation.
