Computed tomography (CT) has been used as an aid in the management of patients presenting with PE, in selected cases. The role of CT-guided pericardiocentesis in contemporary practice, however, remains not fully ascertained. We aimed at presenting a systematic review concerning the state-of-the-art of this technique. METHODS: A systematic review of published data on the use of CT for guiding pericardiocentesis was carried out (search performed on PubMed, ISI Web of Knowledge and Scopus databases). RESULTS: From title and abstract analysis, 14 articles were included that met the prespecified criteria. After full-text analysis, six articles were excluded. The eight articles under analysis included a total of 635 procedures performed in 571 patients. CT guidance was mostly used in a postoperative setting (364 procedures). Most procedures were done mainly for therapeutic purposes (528 procedures). Success rates ranged from 94% to 100%. Complications ranged from 0% to 7.8%. CONCLUSION: CT-guided pericardiocentesis is a useful technique in the approach to PE, in several clinical scenarios. Its use can be especially relevant in the postoperative period, as well as in individuals with suboptimal image quality (as assessed by echocardiography, for the moment the first choice in the approach to most cases of PE).

METHODS: This was a retrospective comparative clinical study conducted in a single institution that included all the patients operated on who had elective isolated on-pump CABG, from March 2006 to June 2014. We evaluated maximum postoperative troponin T (TnT) as a marker of myocardial damage, adjusted for possible confounders using propensity score matching. We also analyzed markers of recovery of myocardial function, and the safety of the intravenous use of Celsior®. RESULTS: During the study period, 261 patients were included, divided in two groups: (a) continuous retrograde blood-based microplegia (114 patients); (b) retrograde single-dose crystalloid Celsior® (147 patients). The propensity score adjusted maximum TnT was significantly lower in the Celsior group [average treatment effect = -0.55 ng/dl; 95% confidence interval (CI) -1.10 to -0.1 ng/dl; p = 0.048]. There were no differences in the postoperative use of intra-aortic balloon of counterpulsation or in the requirements of high-dose inotropic medications. In-hospital mortality was equivalent in both study groups ( p = 0.73); surgical re-exploration because of bleeding was equivalent ( p = 0.37). There were no differences in prolonged mechanical ventilation ( p = 0.65) and intensive care unit length of stay ( p = 0.87). CONCLUSION: An isolated single dose of retrograde Celsior® may be an effective and safe myocardial protection strategy in on-pump CABG.

METHODS: A PubMed literature search (January 2009 to January 2017) was performed using the terms 'dabigatran', 'rivaroxaban', 'apixaban', 'edoxaban', 'atrial fibrillation', 'RE-LY', 'ROCKET AF', 'ARISTOTLE', and 'ENGAGE AF-TIMI 48'. All primary publications and secondary analyses in special populations at increased risk of stroke or bleeding from the pivotal phase III clinical trials were evaluated. RESULTS: Available secondary analyses indicate no treatment interactions with regards to stroke or systemic embolic event (SEE) prevention for any of the DOACs in the patient subgroups, including patients with advanced age, impaired renal function, diabetes, prior stroke, concomitant antiplatelet therapy, heart failure, prior stroke, history of hypertension, myocardial infarction (MI), coronary artery disease, and peripheral artery disease (PAD). Although higher bleeding incidence was reported with dabigatran and rivaroxaban in patients aged 75 years and over with apixaban in patients with diabetes, and with rivaroxaban in patients with previous MI or PAD, no changes in dosing are recommended. CONCLUSIONS: Overall, results of secondary analyses indicate that the recommended dosing strategy for each of the DOACs produces a consistent anticoagulant effect across a diverse patient population, including those at increased risk of stroke or bleeding.

The conventional treatment for CAAD is open repair; however, the operative mortality is high in extensive prosthetic graft replacements. METHODS: A retrospective single-center study was conducted on 74 consecutive patients who underwent endovascular treatment for CAAD in the past 8.5 years. In the partial exclusion (PE) group, entry sites in close proximity to the maximum diameter of CAAD were closed using a stent graft and reentry sites were left without closure. In the complete exclusion (CE) group, we attempted to close all entry and reentry sites. RESULTS: A total of 43 patients (PE group) and 31 patients (CE group) were included with mean ages of 59 and 63 years, respectively. Operative mortalities of 2.3% and 0% were observed in the PE and CE groups, respectively. Complete tear closure was successful in 17 of 31 patients (54.8%) in the CE group. In the PE group, complete thrombosis of the false lumen was achieved in only one case (2.3%). Freedom rates from reentry closure were 90.2%, 86.9%, and 78.2% at 1, 3, and 5 years, respectively. The diameter of the true lumen/aorta changed from 16.9/62.9 mm to 30.2/53.6 mm and from 13.7/55.1 mm to 25.8/51.0 mm in the aortic arch and descending thoracic aorta, respectively. The freedom rates from secondary intervention in successful and unsuccessful CE cases were 92.9% and 69.1%, respectively, at 1 year and 92.9% and 53.7%, respectively, at 3 years. CONCLUSION: Endovascular treatment for CAAD had favorable early and midterm outcomes.

Current pharmacological therapies play an auxiliary role and cannot prevent disease progression, and new treatment methods are needed. In 2011, a plasmid VEGF65-gene therapy drug was approved in Russia for the treatment of chronic lower limb ischemia ( ClinicalTrials.gov identifier: NCT03068585). The objective of this follow-up study was to evaluate the long-term safety and efficacy of gene therapy in patients with limb ischemia of atherosclerotic genesis. AIMS: To evaluate the long-term safety and efficacy of the therapeutic angiogenesis, 36 patients in the treatment group (pl- VEGF165) and 12 patients in the control group participated in a 5-year follow-up study. Planned examinations were carried out annually for 5 years after pl- VEGF165 administration. RESULTS: Differences in the frequency of major cardiovascular events (pl- VEGF165 5/36 versus control 2/12; p = 0.85), malignancies (pl- VEGF165 1/36 versus control 0/12; p = 0.38) and impaired vision (there was none in either group) over the 5-year follow-up period did not achieve statistical significance. The target limb salvage was 95% ( n = 36) and 67% ( n = 12) in the pl- VEGF165 and control groups, respectively. The pain-free walking distance value increased by 288% from 105.7 ± 16.5 m to 384 ± 39 m in the treatment group by the end of the fifth year, with a peak of 410.6 ± 86.1 m achieved by the end of the third year. The ankle-brachial index (ABI) increased from 0.47 ± 0.01 to 0.56 ± 0.02 by the end of the first year, with a subsequent slight decrease to 0.51 ± 0.02 by the fifth year. The maximum increment of transcutaneous oximetry test (tcoO) by 36%, from 66.6 ± 3.7 mm Hg to 90.7 ± 4.9 mm Hg, was observed by the end of the second year. CONCLUSION: The therapeutic effect of angiogenesis induction by gene therapy persists for 5 years.

Mortality from CV disease had plateaued in the recent years raising concerning alarms about the sustained efficacy of available preventive and treatment options. Heart failure (HF) is among the major contributors to the CV-related health care burden, a persisting concern despite the use of clinically proven guideline-directed therapies. A requirement for more efficient medical therapies coupled with recent advances in bio-innovation led to the creation of sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNI), which demonstrated substantial CV benefit when compared with the standard of care, enalapril, in patients with HF and reduced ejection fraction. Further investigations of this novel combination ARNI at the tissue level shed light into the anti-remodeling and cardioprotective effects of sacubitril/valsartan, while clinical studies in the phenotypes of HF with preserved ejection fraction, hypertension and subsets, coronary outcomes, postmyocardial infarction, and renal disease suggested that this combination could be beneficial across a wide spectrum of CV disease. Sacubitril/valsartan is a much-needed therapeutic advance in the avenue of CV disease.

The objective of this study is to evaluate warfarin requirements in hospitalized patients, stratified by BMI. METHODS: This retrospective review included two cohorts of patients: cohort A (patients admitted with a therapeutic international normalized ratio (INR)) and cohort B (newly initiated on warfarin during hospitalization). Exclusion criteria included: age under 18 years, pregnancy, INR (goal 2.5-3.5), and warfarin thromboprophylaxis post orthopedic surgery. The primary outcome was mean total weekly dose (TWD) of warfarin based on weight classification: underweight (BMI <18 kg/m), normal/overweight (BMI 18-29.9 kg/m), obese (BMI 30-39.9 kg/m), and morbidly obese (BMI ⩾ 40 kg/m). Data were extracted from two community hospitals in reverse chronologic order during July 2015-June 2013 until both study institutions evaluated 100 patients per cohort in each BMI classification or until all patients had been evaluated within the prespecified timeframe. RESULTS: A total of 585 patients were included in cohort A (26 underweight, 200 normal/overweight, 200 obese, 159 morbidly obese). There was a statistically significant difference in TWD as determined by one-way analysis of variance ( p < 0.05). A Tukey post hoc test revealed a statistically significantly higher TWD in morbidly obese (41.5 mg) compared with underweight (25.6 mg, p < 0.05), normal/overweight (28.8 mg, p < 0.05) and obese patients (32.4 mg, p < 0.05). In cohort B, 379 patients were evaluated (9 underweight, 166 normal/overweight, 152 obese, 52 morbidly obese). Overall, 191 patients had a therapeutic INR on discharge (88.9% underweight, 52.4% normal/overweight, 44.1% obese, 55.8% morbidly obese, p = 0.035). Of those, there was a statistically significant difference in TWD ( p = 0.021) with a higher TWD in the morbidly obese (41 mg) compared with underweight patients (24.4 mg, p = 0.017). CONCLUSIONS: Based on the results of this study, morbidly obese patients may require higher TWD to obtain and maintain a therapeutic INR.

Elevated plasma low-density lipoprotein cholesterol (LDL-C) levels play a major role in the pathophysiology of ASCVDs. Statins have been shown to reduce ASCVD risk and associated events and are recommended as first-line therapy for treatment of hypercholesterolemia by current international guidelines. The key issue is to attain guideline-recommended LDL-C levels (below 70 mg/dl) for patients at very high cardiovascular risk. However, many high-risk and very-high-risk patients on statin therapy remain beyond treatment goals despite lifestyle modification and statins, and are exposed to a high risk of future cardiovascular events including myocardial infarction (MI), stroke, revascularization procedures, and death. This clearly emphasizes the urgent need for additional LDL-C reduction with new therapeutic strategies to target these highly atherogenic particles and to further reduce the burden of ASCVDs. Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a major role as a key regulator of the hepatic LDL receptor recycling process. Developments over the past 15 years have demonstrated PCSK9 inhibition to be a novel therapeutic strategy to manage increased LDL-C levels. A number of clinical studies using humanized monoclonal antibody technology against PCSK9 have shown profound reductions of LDL-C levels when used either alone or in combination with statin therapy. Recently, the first cardiovascular outcome study demonstrated a significant reduction of ASCV events when evolocumab was added to a statin therapy. This review will discuss current knowledge about antibody-mediated PCSK9 inhibition as add-on therapy to statin and the clinical potential that may be expected.

Current therapies are inadequate in terms of preventing its progression. There are several limitations, such as poor oral bioavailability, side effects, low adherence to treatment, and high dosage frequency of formulations due to the short half-life of the active ingredients used, among others. This review aims to highlight the most relevant aspects of the relationship between the cardiovascular system and the endocannabinoid system, with special attention to the possible translational effect of the use of anandamide in cardiovascular health. The deep and detailed knowledge of this interaction, not always beneficial, and that for years has gone unnoticed, is essential for the development of new therapies. We discuss the most recent and representative results obtained in the field of basic research, referring to the aforementioned subject, emphasizing fundamentally the main role of nitric oxide, renal physiology and its deregulation in pathological processes.

Stenting of the LMCA has emerged as a valid alternative in place of traditional coronary bypass graft surgery. However, in case of mid-shaft/distal lesion, there is no consensus regarding the extension of the strut coverage up to the ostium or to stent only the culprit lesion. Methods We reconstructed a left main-left descending coronary artery (LM-LCA)-left circumflex (LCX) bifurcation after analysing 100 consecutive patients (mean age 71.4 ± 9.3, 49 males) with LM mid-shaft/distal disease. The mean diameter of proximal LM, left anterior descending (LAD) and LCX, evaluated with quantitative coronary angiography (QCA) was 4.62 ± 0.86 mm, 3.31 ± 0.92 mm, and 2.74 ± 0.93 mm, respectively. For the stent simulation, a third-generation, everolimus-eluting stent was virtually reconstructed. Results After virtual stenting, the net area averaged wall shear stress (WSS) of the model and the WSS at the LCA-LCX bifurcation resulted higher when the stent covered the culprit mid-shaft lesion only compared with the extension of the stent covering the ostium (3.68 versus 2.06 Pa, p = 0.01 and 3.97 versus 1.98 Pa, p < 0.001, respectively. Similarly, the static pressure and the Reynolds number were significantly higher after stent implantation covering up the ostium. At the ostium, the flow resulted more laminar when stenting only the mid-shaft lesion than including the ostium. Conclusions Although these findings cannot be translated directly into real practice our brief study suggests that stenting lesion 1:1 or extending the stent to cover the LM ostium impacts differently the rheolytic properties of LMCA bifurcation with potential insights for restenosis or thrombosis.

We review the evidence obtained from a series of clinical trials demonstrating an improvement in adherence to the polypill compared to the use of each compound separately, and found similar or better control of the classical cardiovascular risk factors and a similar safety profile. These results suggest that the use of the polypill could have a beneficial impact in cardiovascular morbidity and mortality. Furthermore, the polypill has the potential to improve cost effectiveness and is simple to use. However, before recommending the implementation of the polypill in programs aimed at primary and secondary cardiovascular prevention, we are awaiting the results of several current clinical trials aimed at measuring the impact on the frequency of major cardiovascular outcomes, particularly in low-medium-income countries.

We measure differential relative gene expression of NLRP1 and NLRP3 inflammasomes in aortic tissues from 30 patients undergoing AAA open repair compared to aortic biopsies from 30 patients undergoing surgery to treat AOD. Aortic wall samples from autopsy without aortic disease were used as controls. NLRP3 was overexpressed in patients with AAA and AOD (RQ 1.185 ± 0.15, and 1.098 ± 0.05, respectively) compared to donors (RQ 1.001 ± 0.08) (OR 2.8, 95% CI 1.2-4.3, p < 0.05 for AAA and OR 2.1, 95% CI 1.1-3.8, p < 0.05 for AOD). NLRP1 gene expression was significantly upregulated in patients with AOD (RQ 1.197 ± 0.09). Meanwhile, NLRP1 was normal expressed in AAA (RQ 1.003 ± 0.07) as well as in autopsy aortic specimens (RQ 1.005 ± 0.11). Enhanced NLRP1 expression in AOD was even significant when compared to AAA (OR 2.3, 95% CI 1.2-3.3, p < 0.05) or controls (OR 2.2, 95% CI 1.1-3.1, p < 0.05). According to our findings, NLRP3 could be involved in the common etiology of AAA and AOD, whereas NLRP1 appears to have a specific role in AOD development.

METHODS: In 2013, a physician notification system for AF detected on a patient's CIED [including pacemakers, implantable cardioverter defibrillators (ICD) or cardiac resynchronization therapy (CRT) devices] was implemented, with a recommendation to consider oral anticoagulation in high-risk patients. We prospectively investigated the effectiveness of this system, and evaluated both patient and physician predictors of anticoagulation, as well as factors influencing physician decision making in prescribing anticoagulation. Both uni- and multivariable analysis as well as descriptive statistics were used in the analysis. RESULTS: We identified 177 patients with device-detected AF, 126 with a CHADS ⩾2. Only 41% were prescribed anticoagulation at any point within 12 months. On multivariable analysis, stroke risk as predicted by CHADS was not a predictor of anticoagulation. ASA use predicted a lower rate of anticoagulation (OR 0.39, 95% CI 0.16-0.97, p = 0.04); physicians in practice for <20 years were more likely to prescribe anticoagulation (OR 3.39, 95% CI 1.28-8.93, p = 0.01); and physicians who believed both cardiologist and family doctor should be involved in managing anticoagulation were more likely to prescribe anticoagulation (OR 3.28, 95% CI 1.02-10.5, p = 0.05). CONCLUSIONS: Patients on aspirin were less likely to be anticoagulated. Physicians in practice for <20 years and who believed that both the general practitioner and cardiologist should be involved in managing anticoagulants were more likely to prescribe anticoagulation.

A femoral vascular access was chosen to treat a coronary lesion with a stent implantation. This femoral vascular access, however, resulted in a pyogenic infection of the ipsilateral hip joint that was not properly diagnosed for an extended post-interventional period. The hip joint completely deteriorated before its underlying cause was identified. This case report illustrates the importance of recognizing potential endovascular complications independently of their frequency.

We examined patients without chronic kidney disease (CKD)/diabetes mellits (DM) [PAD-control], those with DM without CKD, and those with CKD without DM. METHOD: Uni- and multivariate logistic regression was used to assess association of CKD with loss of patency of the pedal-plantar arch and presence of tibial or peroneal vessel occlusion. Multivariate models adjusted for age, sex, hypertension, hyperlipidemia and smoking. RESULTS: A total of 419 patients were included [age 75.2 ± 10.3 years, 288 (69%) male]. CKD nearly doubled the unadjusted odds ratio (OR) for loss of patency of the pedal-plantar arch. After adjustment, association remained significant for severe CKD [estimated glomerular filtration rate (eGFR) ≤ 29 ml/min compared with eGFR ≥ 60 ml/min, adjusted (adj.) OR 8.24 (95% confidence interval {CI} 0.99-68.36, p = 0.05)]. CKD was not related to risk of tibial or peroneal artery occlusion [PAD-control versus CKD, adj. OR 1.09 (95% CI 0.49-2.44, p = 0.83)] in contrast to DM [PAD-control versus DM, adj. OR 2.41 (95% CI 1.23-4.72, p = 0.01), CKD versus DM, adj. OR 2.21 (95% CI 0.93-5.22); p = 0.07)]. CONCLUSIONS: Below the knee (BTK) vascular pattern differs in patients with either DM or CKD alone. Severe CKD is a risk factor for loss of patency of the pedal-plantar arch.
