Objective: Celastrol, a major active constituent of Tripterygium wilfordii, has antioxidant, anti-inflammatory, and anticancer effects. However, whether celastrol can exert protective effect on myocardial ischemia–reperfusion injury (MIRI) is unknown. The aim of this study was to test the protective effect of celastrol on MIRI and elucidate its underlying mechanism.
Methods: Cardiomyocytes (H9c2 cells) were subjected to hypoxia for 8 h followed by reoxygenation for 4 h to create hypoxia/reoxygenation (H/R) model, an in vitro MIRI model. Celastrol was added to the medium 60 min before the H/R process. Cell viability was detected using MTT assay. Myocardial injury was evaluated by measuring lactate dehydrogenase (LDH) and creatine kinase MB isoenzyme (CK-MB) activity. Changes in mRNA and protein expression of TNF-⍺, IL-1β, and nuclear factor-KB (NF-KB) were measured with RT-qPCR assay and western blot analysis.
Results: Results showed that low-dose celastrol (20 and 50 nM) treatment significantly increased cell viability and decreased LDH and CK-MB activity in the condition of H/R, but high-dose celastrol (200 and 400 nM) resulted in extra injury to cardiomyocytes. Moreover, treatment with 50 nM celastrol significantly downregulated mRNA and protein expression of TNF-⍺ and IL-1β. Meanwhile, NF-KB mRNA and protein in the nucleus were also correspondingly reduced.
Conclusion: Our study demonstrated that low-dose celastrol could prevent MIRI in cardiomyocytes by inhibiting the activation of NF-KB, and celastrol may be a potential therapeutic agent for preventing MIRI.

Objective: Early cessation of dual antiplatelet therapy (DAPT) is related to stent thrombosis (ST). The use of second-generation everolimus- and zotarolimus-eluting stents is associated with low restenosis rates and short duration of clopidogrel usage. Non-cardiac surgery in recently stent-implanted patients is associated with major adverse cardiac events (MACEs). Chronic renal failure patients awaiting renal transplantation may also undergo coronary stent implantation prior to surgery. Here we aimed to investigate the safety of early (3 months) DAPT interruption in second-generation drug-eluting stent (DES)-implanted renal transplant recipients.
Methods: In total, 106 previously stent-implanted chronic renal failure patients who underwent renal transplantation were retrospectively enrolled. Three groups were formed according to stent type and the duration of DAPT: early-interruption (3 months from DES implantation), lateinterruption (3–12 months from DES implantation), and bare-metal stent (BMS; at least 1 month from BMS implantation) groups.
Results: Comparison among BMS, DES-early and DES-late groups indicated no difference in ST, myocardial infarction, death, and MACEs. In addition, no difference was observed in ST (p=0.998), myocardial infarction (p=0.998), death (p=0.999), and MACEs (p=0.998) between DES-early and DES-late groups.
Conclusion: Early (3 months) interruption of antiplatelet treatment with second-generation stents before renal transplantation seems to be safe and does not lead to increase in the occurrence of ST and MACEs.

Objective: Psoriasis is a chronic inflammatory disorder, which affects around 1%–3% of the human population worldwide. Cardiovascular events are the leading cause of morbidity and mortality in patients with psoriasis. Some studies have reported that psoriasis is related to increased arrhythmias. The Tp-e interval and Tp-e/QT ratio have been accepted as new markers for the assessment of myocardial repolarization and ventricular arrhythmogenesis. The aim of this study was to assess ventricular repolarization in patients with psoriasis using Tp-e interval and Tp-e/QT ratio.
Methods: The study population consisted of 74 patients with psoriasis and 74 healthy volunteers. The diagnosis of psoriasis was based on a clinical or histopathological examination of all patients. QT interval, corrected QT (QTc), QT dispersion (QTd), Tp-e interval, corrected Tp-e, and Tp-e/QT ratio were measured from the 12-lead electrocardiogram. These parameters were compared between groups.
Results: According to the electrocardiographic parameters, QT and QTc intervals and QTd were significantly higher in patients with psoriasis than in control subjects (p<0.001; p<0.001; p=0.014; respectively). The Tp-e interval, corrected Tp-e, and Tp-e/QT ratio were significantly higher in patients with psoriasis than in control subjects [93±13 milliseconds (ms) vs. 98±14 ms, p=0.040; 104±17 ms vs. 111±17 ms, p=0.008; 0.23±0.03 vs. 0.25±0.03, p<0.001; respectively]. Additionally, the CRP value was an independent predictor of an increased Tp-e/QT ratio (β=0.537, p< 0.001).
Conclusion: Our study revealed that ventricular repolarization features were impaired in patients with psoriasis. Therefore, these patients should be more closely screened for ventricular arrhythmias.

Objective: We aimed to evaluate the relationship of serum activin A levels with risk factors, clinical presentation, biochemical marker levels, extent, and severity of atherosclerotic coronary artery disease (CAD).
Methods: In total, 310 CAD patients [92 with ST-segment elevation myocardial infarction (STEMI), 111 with non-STEMI (NSTEMI), and 107 with unstable angina (UA)] and 207 healthy subjects (controls) were enrolled. Activin A levels in all participants were measured using ELISA. Angiographic measurements were performed in patients and not in the healthy subjects.
Results: Activin A levels were higher in all patient groups than in controls (patients vs. controls, p=0.041; NSTEMI vs. UA, p=0.744; STEMI vs. UA, p=0.172; NSTEMI vs. STEMI, p=0.104). According to the cut-off value of activin A level, patients with high and low activin A levels had a similar distribution of clinical and biochemical variables but the prevalence of severe stenosis was observed in groups with high activin A levels. Our results revealed that activin A levels did not decrease as thrombolysis in myocardial infarction (risk score increased (p=0.590). The area under the ROC curve for activin A levels in patients was 0.590±0.047 (95% CI: 0.439–0.591, p=0.193). In multiple analysis of the overall population, male gender (β=–0.260; 95% CI: –617.39 to –110.04; p=0.005) was an independent predictor of activin A levels.
Conclusion: This study indicated that activin A can not be a predictive marker in CAD and is not associated with extensive and severe CAD. In contrast, the increase in activin A levels in patients, especially in patients with different clinical groups of acute coronary syndromes, suggested its involvement in atherosclerosis.

Objective: It is well known that patients with type 2 diabetes mellitus (T2DM) have a high risk of atrial fibrillation (AF). The current study was designed to determine the relationship between long-term glycemic variability and incidence of new-onset AF in T2DM patients.
Methods: Between January 2008 and December 2009, we conducted a retrospective cohort study in patients with T2DM referred to our hospital. In 505 consecutive patients without any medical history of AF at baseline, the relationship between hemoglobin A1c (HbA1c) variability and future AF incidence was evaluated, with adjustments for other possible confounding factors. HbA1c variability was determined by standard deviation (SD) and coefficient of variation (CV).
Results: Over a median of 6.9-year follow-up period, 48 patients (9.5%) developed incident AF. Multiple cox regression revealed that higher HbA1c-SD (HR: 1.726, 95% CI: 1.104–1.830, p=0.001) or HbA1c-CV (HR: 1.241, 95% CI: 1.029–1.497, p=0.024) remained the remarkable predictor of new-onset AF after adjusting for age, body mass index, left ventricular mass index, and left atrium diameter. Receiver operating curve analysis identified thresholds for HbA1c-SD (0.665%, sensitivity 71.4%, specificity 54.9%) and HbA1c-CV (8.970%, sensitivity 73.8%, specificity 47.1%) to detect new-onset AF development.
Conclusion: In patients with T2DM, higher HbA1c variability is significantly associated with future AF development.

Objective: To identify “genuine” publications from Turkey’s institutions since 1992 that have cumulatively contributed the most to global cardiovascular medicine.
Methods: Based on data from the Web of Science, 146 publications from Turkey were identified having received ≥50 citations as of late July, 2017. Papers with more than a minor share by international authors were excluded.
Results: Hundred and ten primary authors generated 147 medical papers which received ≥50 (interquartile range, 54; 86) citations. These articles corresponded in quality to the top 12% global papers. Half of the articles were published from 2002 to late 2007, with a median exposure period of 12 years. Peak performance was reached in 2004–’07, with a mean of 15–20 papers annually, which then regressed to five papers in 2008–’13, representing an estimated 50% decline. Cardiology generated 105 articles (20 in collaboration with other branches), cardiovascular surgery generated 27 articles, and pediatric cardiology generated 5 articles. Publications arose from 26 medical faculties, Gülhane Military Academy, and 9 hospitals not which were not academically affiliated. The performance of many related Turkish institutions was disappointing.
Conclusion: Turkey’s contribution to cardiovascular medicine has further declined slightly in the current assessment, particularly since 2007. To prevent a further gap in Turkey’s contribution to the field, an undelayed return is needed by building an environment that allows focusing on research with a potential to contribute to medicine.

Objective: Extracorporeal membrane oxygenation (ECMO) is a lifesaving intervention for pediatric patients with respiratory and/or cardiovascular failure. In this study, we evaluated the cardiac catheterization results of pediatric patients on ECMO support.
Methods: Between January 2012 and October 2016, 98 patients (5.2% of all surgery patients) needed ECMO support during perioperative cardiac surgery. We retrospectively reviewed the clinical data of 16 patients who underwent cardiac catheterization under ECMO support.
Results: The median age at catheterization was 6.5 months (range, 3.3–60 months ), and the median weight was 6.0 kg (range, 3.7–16 kg ). Eight of the catheterizations were diagnostic, and the remaining eight were interventional. Five out of these eight patients underwent surgical palliation after diagnostic catheterization. Right pulmonary artery (RPA) stenting, right ventricular outflow tract (RVOT) stenting, combined left pulmonary artery (LPA) and RVOT stenting, combined LPA and modified Blalock-Taussig shunt stenting, bilateral pulmonary artery balloon angioplasty, and bilateral pulmonary artery stenting were each performed once, whereas LPA stenting was performed in two different patients. In one patient undergoing RVOT stenting, a complete atrioventricular block developed, resulting in hypotension; however, this was overcome with an ECMO flow increase. In another patient, the ECMO tubing disconnected from the arterial line. Minor vascular complications were seen in three patients. Twelve patients (75%) were successfully weaned from ECMO after the procedure and ten (63%) were discharged.
Conclusion: Diagnostic and interventional cardiac catheterization can be safely and effectively performed in patients on ECMO. If the patient cannot be weaned from ECMO support, clinicians should consider performing an early angiogram either to treat or clarify the underlying problem.
