Abstract
A bathymetric transect in the north coast of Crete first studied in 1989, was revisited 24 years later. Identical sampling design, season, techniques and protocols were followed in both studies in order to minimize bias in the long-term comparisons. This comprehensive macrofaunal dataset (4 stations, 2 sampling seasons, 7 replicates in each study) revealed changes in benthic diversity and community composition between the sampling periods. The recorded changes were higher at the stations located close to the coastal zone. In addition, while benthic communities showed lower total abundance during the recent sampling period, species abundances were more evenly distributed indicating that some species dominated the historical communities. In spite of these changes, the ecological status remained above the threshold values for good ecological status. The results indicated that changes in the benthic community seem to have been driven by local anthropogenic factors and natural variability rather than by large-scale factors such as nutrients influxes in the entire Mediterranean Basin.

Abstract
Aims Cardiac sarcoidosis (CS) is associated with a poor prognosis. Important features of CS include heart failure, conduction abnormalities, and ventricular arrhythmias. Ventricular tachycardia (VT) is often refractory to antiarrhythmic drugs (AAD) and immunosuppression. Catheter ablation has emerged as a treatment option for recurrent VT. However, data on the efficacy and outcomes of VT ablation in this context are sparse. Methods and results A systematic search was performed on PubMed, EMBASE, and Cochrane database (from inception to September 2016) with included studies providing a minimum of information on CS patients undergoing VT ablation: age, gender, VT cycle length, CS diagnosis criteria, and baseline medications. Five studies reporting on 83 patients were identified. The mean age of patients was 50 ± 8 years, 53/30 (males/females) with a maximum of 56 patients receiving immunosuppressive therapy, mean ejection fraction was 39.1 ± 3.1% and 94% had an implantable cardioverter defibrillator in situ. The median number of VTs was 3 (2.6-4.9)/patient, mean cycle length of 360 ms (326-400 ms). Hundred percent of VTs received endocardial ablation, and 18% required epicardial ablation. The complication rates were 4.7-6.3%. Relapse occurred in 45 (54.2%) patients with an incidence of relapse 0.33 (95% confidence interval 0.108-0.551, P < 0.004). Employing a less stringent endpoint (i.e. freedom from arrhythmia or reduction of ventricular arrhythmia burden), 61 (88.4%) patients improved following ablation. Conclusions These data support the utilization of catheter ablation in selected CS cases resistant to medical treatment. However, data are derived from observational non-controlled case series, with low-methodological quality. Therefore, future well-designed, randomized controlled trials, or large-scale registries are required.

Abstract
BACKGROUND Cardiovascular disease is the leading cause of morbidity and mortality in developed countries. Many patients do not experience symptoms before a first major cardiovascular event. Resting electrocardiogram (ECG) may help identify asymptomatic individuals with a high risk of cardiovascular disease. OBJECTIVE We sought to determine the prevalence of ECG abnormalities in an apparently symptom-free adult population within a prospective registry. METHODS The registry consisted of 4739 consecutive apparently healthy individuals [age 62.8 ± 6.2 (SD) years; 54% female], referred by their General Practitioners between 2009 and 2013. Patient demographics, and clinical data were obtained, alongside blood tests and a resting ECG. RESULTS ECG abnormalities were present in 1509 (31.8%) subjects and were commoner with increasing age (F = 0.161, p = 0.01), systolic (F = 0.134, p = 0.01) and diastolic (F = 0.44, p = 0.01) blood pressure and waist circumference (F = 0.53, p = 0.01). Left ventricular hypertrophy (LVH) was the most common abnormality (n = 281) and was positively associated with systolic (F = 0.12, p = 0.01) and diastolic blood pressure (F = 0.99, p = 0.01) and male gender (X2 = 60.5, p < 0.01). All ECG abnormalities (except for LVH) were associated with an increasing age, while right bundle branch block (F = 0.041, p = 0.01) and atrial fibrillation (n = 29; F = 0.036, p = 0.05) were associated with the presence of diabetes mellitus (n = 211). Only left bundle branch block (n = 50) was associated with angina (F = 0.05, p = 0.01). CONCLUSIONS Unrecognized cardiac abnormalities are common in middle-aged men and women with no overt symptoms. ECG offers the potential to identify these abnormalities and provide earlier intervention and treatment, and possibly improve cardiovascular outcome.

Abstract
BACKGROUND AND OBJECTIVE Atherosclerosis is characterized by a chronic low-grade inflammatory process which can result in atherothrombosis and a number of cardiovascular diseases (CVD). It is believed to be caused by multiple processes that involve inflammation and immunity. Mediterranean Diet (MedD) has been discovered to possess anti-inflammatory properties and associated with a reduction in the CVD risk and mortality. Its main component, extra-virgin olive oil (EVOO), is believed to be largely responsible for these effects and therefore, has been investigated in various studies. The present review article aims to summarize the available literature on the antiinflammatory and cardio-protective effects of EVOO. METHODS A search based on the key concepts "olive oil", "atherosclerosis", "inflammation" and "cardiovascular disease" was performed to retrieve relevant studies and articles on the association between the consumption of EVOO and the levels of inflammatory biomarkers as well as CVD incidence and mortality from online databases; Pubmed, Embase and Cochrane Library. RESULTS Consumption of EVOO is associated with a reduction in inflammatory biomarkers and molecules implicated in atherosclerosis as well as CVD incidence and mortality as well as other complications such as heart failure and atrial fibrillation. Moreover, these anti-inflammatory and cardioprotective effects of EVOO are mostly attributable to its high content of polyphenol molecules. CONCLUSION Currently available evidence supports the anti-inflammatory and cardio-protective roles of EVOO. However, there is limited amount of available randomized controlled trials especially lacking those investigating the use of EVOO as secondary prevention, heterogeneity of study design, limited generalization to wide population groups, and inability to determine the minimum intake of EVOO required to clinically achieve the anti-inflammatory and cardioprotective effects. Therefore, more highquality randomized controlled trials still need to be carried out to overcome these challenges to further assess the health benefits of EVOO consumption and potentially translate it into clinical practice as primary or secondary prevention of atherosclerosis-related conditions.

Abstract
INTRODUCTION Arrhythmias can cause symptoms ranging from simple dizziness to life-threatening circulatory collapse. Current management includes medical therapy and procedures such as catheter ablation or device implantation. However, these strategies still pose a risk of serious side effects, and some patients remain symptomatic. Advancement in our understanding of how arrhythmias develop on the cellular level has made more targeted approaches possible. In addition, contemporary studies have found that several genes are involved in the pathogenesis of arrhythmias. AREAS COVERED In the present review, the authors explore the cellular and genetic mechanisms leading to arrhythmias as well as the progress that has been made in using both gene and cell therapy to treat tachy- and bradyarrhythmias. They also consider why gene and cell therapy has resulted into a few clinical trials with promising results, however still not applicable in routine clinical practice. EXPERT OPINION The question currently is whether such biological therapies could replace current established approaches. The contemporary evidence suggests that despite recent advances in this field, it will need more work in experimental models before this is applied into clinical practice. Gene and cell studies targeting conduction and repolarization are promising, but still not ready for use in the clinical setting.

Abstract
BACKGROUND Low-density lipoprotein cholesterol (LDL), and especially its oxidized form, renders the atherosclerotic plaque vulnerable to rupture in acute coronary syndromes (ACS). On the other hand, high-density lipoprotein (HDL) is considered an anti-atherogenic molecule. The more recent HDL-targeted drugs may prove to be superior to those used before. Indeed, delipidated HDL and HDL mimetics are efficient in increasing HDL levels, while the apoA-I upregulation with RVX-208 appears to offer a clinical benefit which is beyond the HDL related effects. HDL treatment however has not shown a significant improvement in the outcomes of patients with ACS so far, studies have therefore focused again on LDL. In addition to statins and ezetimibe, novel drugs such as PSCK9 inhibitors and apolipoprotein B inhibitors appear to be both effective and safe for patients with hyperlipidemia. CONCLUSION Data suggest these could potentially improve the cardiovascular outcomes of patient with ACS. Yet, there is still research to be done, in order to confirm whether ACS patients would benefit from LDL- or HDL-targeted therapies or a combination of both.

Abstract
Age is an adverse prognostic factor in patients with heart failure. We aimed to assess the impact of age and noncardiac co-morbidities in the outcome of patients undergoing cardiac resynchronization therapy (CRT), and determine which of these two factors is the most important predictor of survival. The study involved a single-center retrospective assessment of 697 consecutive CRT implants during a 12-year period. Patient co-morbidity profile was assessed using the Charlson Co-morbidity Index (CCI) and the Charlson Age-Co-morbidity Index (CACI). Predictors of survival free from heart transplantation were assessed. CRT-related complications and cause of death analysis were assessed within tertiles of the CACI. During a mean follow-up of 1,813 ± 1,177 days, 347 patients (49.9%) died and 37 (5.3%) underwent heart transplantation. On multivariate Cox regression, female gender (HR = 0.78, 95% confidence interval [CI] 0.62 to 0.99, p = 0.041), estimated glomerular filtration rate (HR per ml/min = 0.99, 95% CI 0.98 to 0.99, p < 0.001), left ventricular ejection fraction (HR per % = 0.99, 95% CI 0.98 to 1.00, p = 0.022), New York Heart Association class (HR = 1.83, 95% CI 1.53 to 2.20, p < 0.001), presence of left bundle branch block (HR = 0.70, 95% CI 0.56 to 0.87, p = 0.001), and CACI tertile (HR = 1.37, 95% CI 1.18 to 1.59, p < 0.001) were independent predictors of all-cause mortality or heart transplantation. Compared with age and the CCI, the CACI was the best discriminator of all-cause mortality. Inappropriate therapies occurred less frequently in higher co-morbidity tertiles. In conclusion, patient co-morbidity profile adjusted to age impacts on mortality after CRT implantation. Use of the CACI may help refine guideline criteria to identify patients more likely to benefit from CRT.

Abstract
BACKGROUND Stable angina is a debilitating and progressive disease caused by narrowing of the coronary arteries, which in turn affects cardiac perfusion. Statins have a well-established role, modifying symptoms and progression of the disease not only through lipid lowering, but also through pleiotropic effects. OBJECTIVE We sought to evaluate the effect of statins in stable angina pectoris Method: We performed a systematic review of the literature searching MEDLINE via Pubmed for all studies which examine the possible effects of statins in stable angina pectoris. RESULTS Statins have demonstrated favourable modification of both biochemical markers (oxidative stress, inflammatory and coagulation markers/factors) and clinical symptoms (anginal and ischemic) of the disease. These effects have been demonstrated in vitro, ex vivo and in vivo in animals and humans, independently of the lipid lowering effects. CONCLUSION With an excellent safety profile and evidence of efficacy in managing patients with stable angina, statins appear an essential part of the therapeutic armoury against atherosclerotic disease.

Abstract
BACKGROUND Dual-site right ventricular pacing (Dual RV) has been proposed as an alternative for patients with heart failure undergoing cardiac resynchronization therapy (CRT) with a failure to deliver a coronary sinus (CS) lead. Only short-term hemodynamic and echocardiographic results of Dual RV are available. We aimed to assess the long-term results of Dual RV and its impact on survival. METHODS Multicenter retrospective assessment of all CRT implants during a 12-year period. Patients with failed CS lead implantation, treated with Dual RV, were followed and assessed for the primary endpoint of all-cause mortality and/or heart transplant. A control group was obtained from contemporary patients using propensity matching for all available baseline variables. RESULTS Ninety-three patients were implanted with Dual RV devices and compared with 93 matched controls. During a median of 1,273 days (interquartile range 557-2,218), intention-to-treat analysis showed that all-cause mortality and/or heart transplant was higher in the Dual RV group (adjusted hazard ratio [HR] = 1.66, 95% confidence interval [CI] 1.12-2.47, P = 0.012). As-treated analysis yielded similar results (HR = 1.97, 95% CI 1.31-2.96, P = 0.001). Cardiac device-related infections occurred seven times more frequently in the Dual RV site group (HR = 7.60, 95% CI 1.51-38.33, P = 0.014). Among Dual RV nonresponders, four had their apical leads switched off, five required an epicardial LV lead insertion, a transseptal LV lead was implanted in two, and in nine patients, after reviewing the CS venogram, a new CS lead insertion was successfully attempted. CONCLUSION Dual RV pacing is associated with worse clinical outcomes and higher complication rates than conventional CRT.

Abstract
The age of initiation and the rate of progression of atherosclerosis vary markedly among individuals and have been difficult to predict with traditional cardiovascular risk assessment models. Although these risk models provide good discrimination and calibration in certain populations, cardiovascular disease (CVD) risk may not be accurately estimated in low- and intermediate risk individuals. Therefore, imaging techniques such as Ankle-Brachial Index (ABI), Coronary Artery Calcium score (CAC), carotid Intima-Media Thickness (cIMT), flow mediated dilation (FMD) and Positron Emission Tomography (PET) have been developed and used to reclassify these individuals. In the present article we review the role of the most commonly used imaging techniques for CVD risk assessment.

Abstract
AIMS Colchicine has been suggested to be beneficial in preventing recurrent pericarditis. The goal of this study was to review all randomized controlled trials that assess the use of colchicine for the prevention and treatment of cardiac diseases. METHODS We performed a meta-analysis of the effects of colchicine on pericarditis, postpericardiotomy syndrome and postprocedural atrial fibrillation recurrence, in-stent restenosis, gastrointestinal adverse effects, and treatment discontinuation rates. We conducted an EMBASE and MEDLINE search for prospective controlled trials. RESULTS We identified 17 prospective controlled randomized studies with 2082 patients that received colchicine and 1982 controls with an average follow-up duration of 12 months. Treatment with colchicine is associated with reduced risk of pericarditis recurrence/postpericardiotomy syndrome (OR: 0.37; 95% CI: 0.29-0.47; P<0.001) and lower recurrence of atrial fibrillation rates after cardiac surgery and ablation procedures. However, gastrointestinal side effects were more common in patients treated with colchicine (OR: 2.6; 95% CI: 1.82-3.72; P<0.001) in all subgroups except for those treated for prevention of recurrent pericarditis. The higher rates of side effects resulted in higher incidence of treatment discontinuation in patients treated with colchicine. CONCLUSION Colchicine appears to be efficacious and well tolerated for recurrent pericarditis/postpericardiotomy syndrome and recurrence of postprocedural atrial fibrillation. However, its efficacy may be limited by its gastrointestinal adverse events and treatment discontinuation rates particularly in postoperative patients.

Abstract
INTRODUCTION AND OBJECTIVES We examined whether the rs180070 and rs2070011 polymorphisms of the fibrinogen gene could affect the risk of coronary artery disease in hypertensive patients by modifying the inflammatory process and coagulation. METHODS A total of 744 participants underwent coronary angiography due to symptoms of stable angina, while hypertension was present in 332 patients. RESULTS The presence of the A allele (rs180070) was associated with significantly high levels of fibrinogen in hypertensive patients (P=.05). On multivariate analysis, A homozygosity (rs180070) (β = 0.257 ± 18.6; P<.001), but not hypertension status (β = 0.05 ± 11.9; P=.29) was an independent predictor of fibrinogen levels. In hypertensive patients, higher fibrinogen levels>443mg/dL (odds ratio = 3.50; 95% confidence interval, 1.14-10.90; P=.029), but not A homozygosity (odds ratio = 3.00; 95% confidence interval, 0.78-11.90; P = .110) were independent predictors of the presence of coronary artery disease. Moreover, interleukin-6 levels were higher in A homozygotes for the rs180070 polymorphism compared with all other genotypes (P=.046). Indeed, this genotype was the only adjusted independent predictor of interleukin-6 levels (β = 0.151 ± 0.642; P=.032). It was also associated with higher D-dimer levels in hypertension compared with G allele carriers (P=.048). CONCLUSIONS The presence of A homozygosity (rs180070) is associated with increased levels of inflammatory mediators and a higher incidence of angiographic coronary artery disease. Importantly, fibrinogen is an independent predictor of the angiographic presence of coronary artery disease in hypertensive patients.

Abstract
We read with interest the article entitled "Circulating microRNAs characterizing patients with insufficient coronary collateral artery function" which was recently published in the PLOS ONE journal. It was demonstrated for the first time that specific circulating microRNAs (miRNAs) can distinguish patients with sufficient from those with insufficient coronary collateral circulation. Circulating miRNAs in the plasma of patients with stable CAD and chronic CTO could provide information with regard to the coronary collateral artery capacity. However, several aspects need to be taken into consideration before the use of miRNAs in the clinical practice. A risk model that would incorporate risk factors for cardiovascular disease and miRNAs could prove to be very useful. Although an association between the levels of miRNAs and the collateral artery capacity appears promising, it still does not confirm any causal role for miRNAs. Therefore, large clinical studies in populations with CTO are warranted to evaluate this finding.

Abstract
Asymmetric dimethylarginine (ADMA) is a competitive endogenous inhibitor of nitric oxide synthase with a key role in the pathophysiology of endothelial dysfunction, in the progression of atherosclerosis and in cardiovascular diseases. Statins, renin-angiotensin-aldosterone system inhibitors, blood glucose lowering agents, insulin sensitizers, beta-blockers, estrogen replacement therapy, antioxidants, complex B vitamins, L-arginine and acetylsalicylic acid have been evaluated for their ability to reduce ADMA levels or inhibit its actions. Despite the major beneficial effects of these agents in cardiovascular disease, research has shown that their favorable actions are only partially mediated by reducing ADMA levels or by bypassing its effect in nitric oxide synthesis. Novel therapeutic approaches targeting selectively ADMA are encouraging, but have only been tested in vitro or in animal studies and further research is needed in order to conclude on how therapeutic strategies modulating ADMA actions can affect atherosclerosis progression and cardiovascular diseases.

Abstract
Atherosclerosis is currently regarded as a chronic inflammatory disease that is mediated by several types of cells and molecules. Emphasis has been placed on the role of cytokines and the way they act and interact to initiate and sustain inflammation in the microenvironment of an atherosclerotic plaque. Cytokines are invariably expressed by all cells involved in the pathogenesis of atherosclerosis, act on a variety of targets exerting multiple effects and are largely responsible for the crosstalk among endothelial, smooth muscle cells, leukocytes and other vascular residing cells. In the present paper our aim is to review current information on the role of the most commonly discussed cytokines in the process of atherogenesis and to discuss the prognostic significance of these cytokines in atherosclerosis and coronary artery disease.
