Behaviour of protein carbonyl groups in juvenile myocardial infarction.

Acute myocardial infarction (AMI) is accompanied by oxidative stress, and protein oxidation is among the con- sequences of oxidative stress. We examined the plasma concentration of protein carbonyl groups (PC), a marker of protein oxidation, in a group of young subjects with AMI (45 men and 5 women; mean age 40.4 ± 4.8 yrs). We found a significant increase of PC (p < 0.001) in comparison with normal controls. No difference was observed between patients with AMI char- acterized by elevated ST segment and those without elevation of ST segment. There was no correlation between the ejection fraction and PC in the whole group nor in the subgroups of STEMI and non-STEMI patients. Subdividing the …

Behaviour of the neutrophil to lymphocyte ratio in young subjects with acute myocardial infarction

In the last years the neutrophil to lymphocyte ratio (NLR) has been examined in cardiovascular disorders and in particular in coronary artery disease and acute myocardial infarction (AMI). Now we examined this parameter in subjects with juvenile myocardial infarction at the initial stage and after 3 and 12 months. We enrolled 123 young subjects (112 men and 11 women, mean age 39.4 ± 5.8 yrs) with AMI. The time interval between the AMI onset and the investigation was 13 ± 7 days. The mean value of NLR observed in young AMI subjects was significantly increased compared to normal controls (N = 1.817 ± 0.711; young AMI subjects = 2.376 ± 0.873, p <  0.0001). NLR does not discriminate STEMI (2.4…
