Systemic immune-inflammation index (SII), on the basis of lymphocyte, neutrophil and platelet counts had been published to be a good prognostic factor in coronary artery disease. Nevertheless, the ...

Aims: Chronic coronary syndrome is associated with several risk factors, such as dyslipidemia and hypertension. The atherogenic index of plasma (AIP) has been demonstrated to be a biochemical risk factor for coronary artery disease (CAD). This study aimed to determine whether the AIP is an effective parameter for estimating obstructive CAD. Methods and Results: A total of 345 patients (with a mean age of 62.2 ± 10.3; 63% male) who underwent coronary angiography were included in this study. Obstructive CAD is defined as having one or more vessels with a stenosis level of ≥50%. Depending on the presence of obstructive CAD, all patients were divided into two groups. The mean AIP value was found to be 0.538 ± 0.26 in the study group. The AIP values were significantly higher in the obstructive coronary artery group (AIP; 0.49 ± 0.26 vs. 0.58 ± 0.27, p = 0.002). According to a univariable analysis, AIP values were significantly associated with obstructive coronary artery disease [OR: 3.74 (CI 95% 1.62–8.64), p = 0.020]. The AIP was further adjusted for confounding risk factors in three multivariable analysis models and, all three models showed a significant association. According to an ROC analysis, 0.49 is the cut-off value for AIP, and a value above 0.49 indicates 50% coronary artpery stenosis. Conclusions: The AIP may be used in the assessment of cardiovascular risk for patients with stable angina pectoris, and it may also be used to estimate obstructive CAD.

Cardioneuroablation is one of the emerging therapies in vasovagal syncope. In this study, we present a simple method of cardioneuroablation performed via a right-sided approach, targeting anterior-right and right-inferior ganglionated plexi, along with procedural and follow-up data. Patients who had underwent cardioneuroablation between March 2018 and September 2019 with vasovagal syncope in 2 clinics were enrolled in the study. All patients underwent radio-anatomically guided radiofrequency ablation targeting anterior-right ganglionated plexi and right-inferior ganglionated plexi. Syncope and symptom burden, 24-hour ambulatory electrocardiogram data at presentation, and at follow-up were assessed along with procedural data. A total of 23 patients underwent modified right-sided cardioneuroablation. Mean basal cycle length decreased significantly from 862.3 ± 174.5 ms at the beginning of the procedure 695.8 ± 152.1 ms following the final radiofrequency ablation (P < .001). Mean 24-hour ambulatory heart rate increased significantly from 66.4 ± 10.7 bpm at baseline to 80 ± 7.6 bpm at follow-up (P < .001). Only 1 patient had 1 episode of syncope following the procedure at the mean follow-up period of 10 ± 2.9 months. The same patient had recurrent presyncope. The right-sided cardioneuroablation approach was found to be an effective treatment for vasovagal syncope and may be regarded as a default initial cardioneuroablation technique.
