Summary Background Materials and methods Results Conclusions

In patients with ST-elevation myocardial infarction (STEMI), the relationship between transaminases and myocardial damage detected by cardiac magnetic resonance (CMR) imaging is unknown and the prognostic value incompletely investigated.
CMR imaging was performed in 167 STEMI patients 2.3 [1.6–3.9] days after primary percutaneous coronary intervention (PPCI). Blood samples for transaminase measurement (aspartate transaminase (AST) and alanine transaminase (ALT)) were obtained serially from day 1 to day 4 after PPCI. Patients were followed for major adverse cardiac events (MACE) for 2.7 [1.1–3.3] years.
Admission and peak concentrations of AST and ALT were significantly associated with ejection fraction (p < 0.001), infarct size (p < 0.001), and the presence of microvascular obstruction (p < 0.01). Peak values of both transaminases showed a stronger correlation with CMR parameters than admission values (all p < 0.05). In Kaplan–Meier analysis, a high peak AST or high peak ALT was associated with reduced MACE-free survival (both p < 0.01), whereas admission values were not (both p > 0.05). Peak AST (hazard ratio (HR): 4.93 [1.70–14.32], p = 0.003) and peak ALT (HR: 5.67 [1.94–16.56], p = 0.002) were independent predictors of MACE after adjusting for clinical risk factors.
Transaminases measured in the acute phase after PPCI for STEMI are associated with systolic dysfunction, more extensive myocardial necrosis and microvascular injury with subsequent prognostic information on MACE at long-term follow-up.
