Beat-to-beat variation may lead to ED in patients with paroxysmal lone AF and questioning erectile function in patients with lone AF may be recommended.

The presence of fQRS complex, as a simple and feasible ECG marker, seems to be a novel predictor of in-hospital adverse events and long-term all-cause mortality in PE patient population. This parameter may utilize the identification of patients whom at higher risk for mortality and individualization of therapy.

OBJECTIVE:The predictive value of the fibrinogen-to-albumin ratio has been evidenced in coronary artery disease. Available data demonstrated that inflammation and oxidative stress are the relevant mechanisms of ascending aortic aneurysm formation and dilatation.The fibrinogen-to-albumin ratio reflects oxidative stress and inflammation. This study investigated the correlation between fibrinogento-albumin ratio and ascending aortic aneurysm.METHODS: A total of 250 consecutive patients with ascending aortic aneurysm and 250 consecutive patients with normal ascending aortic diameter were included in the study using comprehensive transthoracic echocardiography. All data and fibrinogen-to-albumin ratio were compared between two groups. RESULTS:The fibrinogen-to-albumin ratio levels were significantly higher in ascending aortic aneurysm group compared with normal ascending aortic diameter group (p<0.001). Also, there was significantly positive correlation between the diameter of the ascending aorta and the fibrinogen-to-albumin ratio (p<0.001).CONCLUSION: Fibrinogen-to-albumin ratio is associated with ascending aortic aneurysm and may serve as blood marker for identifying high-risk patients.

Entrainment is an important tool for the diagnosis and location of reentry. The usefulness of this maneuver requires that, prior to cessation of ventricular pacing, the atrial rate accelerates to the ventricular pacing rate. Moreover, it is important to verify the continuation of the tachycardia following cessation of entrainment. The recognizing the last entrained atrial beat is utmost important to avoid erroneous A–A–V labeling.

Objective:Previous studies revealed the relationship between stable coronary artery disease (CAD) and serum adropin level, but this relationship has not been investigated in patients with non-ST segment elevation myocardial infarction (NSTEMI). The present study is an analysis of the relationship between adropin and severity of CAD assessed based on SYNTAX score in patients with NSTEMI.Methods:A total of 109 participants, 80 patients with NSTEMI and 29 healthy individuals, were prospectively enrolled in the study. Patients with NSTEMI were divided to 2 groups: high SYNTAX score (≥32) (35 patients) and low SYNTAX score (<32) (45 patients). Adropin level was measured from blood serum samples using enzyme-linked immunosorbent assay test.Results:Patients with NSTEMI and high SYNTAX score had significantly lower serum adropin level (2357.30 pg/mL±821.58) compared to NSTEMI patients with low SYNTAX score (3077.00 pg/mL±912.86) and control group (3688.00±956.65). Adropin cut-off value for predicting high SYNTAX score on receiver-operating characteristic curve analysis was determined to be 2759 pg/mL, with a sensitivity of 63% and a specificity of 57%. Adropin was an independent predictor for high SYNTAX score (odds ratio=0.999; 95% confidence interval: 0.998–1.000; p=0.007).Conclusion:Adropin could be an alternative blood sample value for predicting severity of CAD.
