Abstract

Aims

Ischemia-induced left ventricular (LV) diastolic dysfunction (DD) is increasingly recognized as a therapeutic challenge. While DD during acute myocardial infarction (AMI) determines patients’ prognosis, it is unknown how LV remodeling after AMI affects the development of DD. Therefore, we aimed to identify AMI characteristics, which determine diastolic function after 5 years.

Methods and results

41 patients with reperfused AMI and intracoronary infusion of progenitor cells were included into the present analysis of the TOPCARE-AMI trial. At 5-year follow-up, we determined LV diastolic function including LV-filling index (E/E′) by echocardiography. Diastolic function was normal in 21 patients (DD class 0), impaired in 14 patients (DD class 1) and pseudonormal in 6 patients (DD class 2). E/E′ increased from DD class 0 to 2 (6.6 ± 1.3 vs. 9.0 ± 2.4 vs. 12.1 ± 6.2; p < 0.01). E/E′ correlated with the maximal creatine kinase activity during AMI (CKMBmaxr = 0.73, p < 0.01), the change in end-diastolic or end-systolic LV volumes between AMI and 4 months (∆LVEDV r = 0.67, p < 0.01; ∆LVESV r = 0.58, p < 0.01), ejection fraction at 5 years (r = −0.47, p < 0.01) and NT-proBNP serum levels at 5 years (r = 0.37, p < 0.05). Multivariate analysis revealed CKMBmax (β = 0.56, p < 0.01) and ∆LVEDV (β = 0.38, p < 0.01) as independent predictors for E/E′ 5 years after AMI.

Conclusion

Adverse early remodeling processes (reflected by LV dilatation between infarction and 4 months) determine long-term diastolic function in patients after reperfused AMI and progenitor cell therapy.
