Serum Salusin Levels in ST-Segment Elevation Myocardial Infarction.

BACKGROUND: In our study, we aimed to determine the change in levels of salusin-alpha and salusin-beta at admission and after the treatment in patients with STEMI, who have active atherosclerosis. METHODS: Serum salusin-alpha and beta levels of 50 patients diagnosed with STEMI in the emergency department were measured at admission and on 7th day post-treatment and compared with serum salusin levels of 50 healthy volunteers. RESULTS: In STEMI patients, salusin-alpha levels were found to be significantly decreased (p < 0.001) and salusinbeta levels were found to be significantly increased (p < 0.001) compared to healthy volunteers in the control group. 7th day post-treatment salusin-alpha levels were found to be lower and salusin-beta levels were found to be at a higher level compared to healthy individuals (p < 0.001). Negative correlation (r = -.322 p = 0.023) was found between salusin-alpha levels and pulse rate. But no significant correlation was found between salusin-beta levels and biochemical parameters. CONCLUSIONS: The data of this study support the fact that salusin-alpha levels decrease and salusin-beta levels increase in acute cases such as STEMI.

The association between apelin-12 levels and paroxysmal supraventricular tachycardia.

AIMS: Our aim was to investigate the apelin-12 levels in patients with atrioventricular tachyarrhythmias and compare with those in patients with lone atrial fibrillation. METHODS: Forty four patients with supraventricular tachycardia as atrial fibrillation, 44 patients with paroxysmal supraventricular tachycardia (P-SVT) as atrioventricular tachyarrhythmias, including atrioventricular nodal reentrant tachycardia or atrioventricular reentrant tachycardia, and 30 age- and sex-matched healthy individuals were included in the study. RESULTS: The apelin-12 levels were significantly lower in both atrial fibrillation and P-SVT groups than control group. In post-hoc analysis, there was no significant difference in apelin-12 levels between atrial fibrillation and P-SVT groups (P = 0.9). Patients in atrial fibrillation group and patients in P-SVT group had significantly lower apelin-12 levels than control group, separately (P < 0.001 and P < 0.001, respectively). The sensitivity and specificity values of the apelin-12 levels for predicting SVT, including both atrial fibrillation and atrioventricular reentrant tachycardia or atrioventricular nodal reentrant tachycardia were 64.77 and 90%, respectively (cut-off value was 0.87). The area under the receiver operator characteristic curve was 0.834 for the apelin-12 levels (P = 0.0001). CONCLUSION: Apelin-12 levels are lower in patients with atrial fibrillation and P-SVT than control groups. Lower apelin levels in patients with atrial fibrillation and P-SVT would be expected to result in a decrease in the conduction velocity.
