RESUMO
BACKGROUND: New-onset postoperative atrial fibrillation (POAF) after coronary artery bypass surgery (CABG) occurs with an incidence of 20-40%. The clinical relevance of POAF remains a concern, and the need for further studies regarding the clinical management of POAF is necessary. AIM: The AFRODITE study, a prospective multicenter cohort study, had as its primary endpoint the evaluation of AF recurrence in patients post CABG over a one-year period. METHODS: Two hundred twenty-eight patients aged >50 years who underwent isolated CABG were included in the study. Patients were stratified into two groups, POAF and non-POAF, and followed for 12 months for AF recurrence, hospitalizations, and death. RESULTS: Two hundred twenty-eight patients (mean age 67 years, 88.6% male) were included in the study. 28.5% of patients experienced at least one episode of POAF during index hospitalization (POAF group) and were compared with the non-POAF group (n = 163). Multivariate stepwise logistic regression analysis showed that the strongest prognostic parameter for POAF was the CHA2DS2-VASc score (odds ratio = 1.61, p < 0.001). POAF patients had a worse in-hospital outcome, but the incidence of long-term AF recurrence was not statistically different (3.6% vs. 4.8%, p = 0.9). CONCLUSION: Interestingly, a one-year prospective follow-up of patients in the study did not reveal significant differences between POAF and non-POAF patients. A notable finding was that patients with a higher CHA2DS2-VASc score were more likely to develop POAF.
RESUMO
According to the 2021 European Society of Cardiology guidelines, the four pillars of medical therapy in heart failure with reduced ejection fraction (HFrEF) include sodium-glucose co-transporter-2 inhibitors, beta-blockers, mineralocorticoid receptor antagonists, and angiotensin-converting enzyme inhibitors or angiotensin receptor-neprilysin inhibitors. However, in clinical practice, concomitant use of all four drug groups in target doses is often limited by their intolerance or fear of potential complications. Herein, we present strategies to initiate or modify HFrEF therapy in frequent but challenging clinical scenarios (symptomatic hypotension, atrial fibrillation, kidney disease or worsening renal function, hyperkalemia) in a way that does not lead to unnecessary reduction or cessation of life-saving treatment.

RESUMO
Hyponatraemia is very common in heart failure (HF), especially in decompensated patients. It is associated with increased mortality and morbidity and considered a marker of advanced disease. Recognition of hyponatraemia and its causes may help guide treatment strategy. Historically, therapy has primarily focused on water restriction, decongestion with loop diuretics in case of volume overload (dilutional hyponatraemia) and sodium repletion in case of depletion. In this review, we summarise the potential benefits of established and emerging HF therapies on sodium homeostasis, with a focus on dual vasopressin antagonists, angiotensin receptor-neprilysin inhibitors, sodium-glucose cotransporter 2 inhibitors and hypertonic saline, and propose a potential therapeutic approach for hyponatraemia in HF.

Aims: To evaluate the impact of lockdown during the COVID-19 pandemic on lifestyle changes of the general population, and on admissions for acute coronary syndrome (ACS). Methods and Results: All ACS admissions during the COVID-19 lockdown (10 March to 4 May, 2020), in 3 municipalities (3 spoke, and 1 hub hospital), in Southwestern Greece (411,576 inhabitants), were prospectively recorded and compared to the equivalent periods during 2018, and 2019. A telephone survey of 1014 participants was conducted to explore the lifestyle habits of citizens aged ≥35-years-old before and during lockdown. The median ACS incidence rate decreased from 19.0 cases per week in 2018 and 21.5 in 2019 down to 13.0 in 2020 (RR: 0.66 during the Covid-19 lockdown; 95%CI: 0.53-0.82; P = 0.0002). This was driven by a significant reduction of admissions for Non-ST elevation myocardial infarction (NSTEMI) (RR: 0.68; 95%CI: 0.52-0.88; P = 0.0037), mainly in patients with a lower burden of cardiovascular risk factors, as we noticed an inverse association between the reduction of the incidence of ACS during the Covid-19 lockdown period and the number of registered patient risk factors. There was no difference in the rates of STEMI and population-based all-cause mortality across the examined time periods. The telephone survey demonstrated reduction of passive smoking, working hours, alcohol, junk food and salt consumption, and an increase in sleeping hours, mainly in participants with a lower burden of cardiovascular risk factors. Conclusions: A significant decline in ACS admissions during the COVID-19 lockdown was noted, affecting mainly NSTEMI patients with a lower burden of cardiovascular risk factors. This was accompanied by significant lifestyle changes. Thus, it is tempting to speculate that to some extend the latter might be associated with the observed decline in ACS admissions.
RESUMO
AIMS: The Heart Failure Association (HFA) of the European Society of Cardiology (ESC) developed the HFA Atlas to provide a contemporary description of heart failure (HF) epidemiology, resources, reimbursement of guideline-directed medical therapy (GDMT) and activities of the National Heart Failure Societies (NHFS) in ESC member countries. METHODS AND RESULTS: The HFA Atlas survey was conducted in 2018-2019 in 42 ESC countries. The quality and completeness of source data varied across countries. The median incidence of HF was 3.20 [interquartile range (IQR) 2.66-4.17] cases per 1000 person-years, ranging from ≤2 in Italy and Denmark to >6 in Germany. The median HF prevalence was 17.20 (IQR 14.30-21) cases per 1000 people, ranging from ≤12 in Greece and Spain to >30 in Lithuania and Germany. The median number of HF hospitalizations was 2671 (IQR 1771-4317) per million people annually, ranging from <1000 in Latvia and North Macedonia to >6000 in Romania, Germany and Norway. The median length of hospital stay for an admission with HF was 8.50 (IQR 7.38-10) days. Diagnostic and management resources for HF varied, with high-income ESC member countries having substantially more resources compared with middle-income countries. The median number of hospitals with dedicated HF centres was 1.16 (IQR 0.51-2.97) per million people, ranging from <0.10 in Russian Federation and Ukraine to >7 in Norway and Italy. Nearly all countries reported full or partial reimbursement of standard GDMT, except ivabradine and sacubitril/valsartan. Almost all countries reported having NHFS or working groups and nearly half had HF patient organizations. CONCLUSIONS: The first report from the HFA Atlas has shown considerable heterogeneity in HF disease burden, the resources available for its management and data quality across ESC member countries. The findings emphasize the need for a systematic approach to the capture of HF statistics so that inequalities and improvements in care may be quantified and addressed.

AIM: We sought to investigate the impact of IVUS use on chronic total occlusion (CTO) PCI using data from a contemporary registry of consecutive patients and applying a propensity score matching analysis. METHODS AND RESULTS: We evaluated 514 successful CTO-PCIs, median age: 67 years (IQR: 58-73), 83.5% males. IVUS-guided PCI was performed in 184 (35.8%) of cases. After using 1:1 propensity matching score analysis, two groups of 182 patients each (IVUS-guided vs. angiography-guided CTO-PCI group) were produced to form the study population. In the IVUS-guided group the median maximum stent diameter was larger and the median total stented segment was longer compared to the angiography-guided group [(3.5 mm, IQR: 3.0-4.0 vs. 3.2 mm, IQR: 3.0-3.5, p < 0.001) and (60.0 mm, IQR: 38.0-91.3 vs. 38.0 mm, IQR: 32.0-70.5, p < 0.001), respectively]. In the IVUS-guided group, retrograde recanalization was more frequently encountered compared to the angiography-guided PCI group (30.2% vs. 20.9%, p = 0.04). Procedural time was significantly longer in the IVUS-guided group, without any difference in fluoroscopy time, radiation dose and contrast volume. Multivariate linear regression analysis showed that IVUS use was the strongest independent factor associated with larger maximum diameter stents (p < 0.001) and a strong independent predictor for total stented segment length during CTO-PCI (p < 0.001). Up to 8 years follow-up, there was no difference in the incidence of the composite endpoint of all-cause death, cardiac death, myocardial infarction and target vessel revascularization between the IVUS-guided PCI and the angiography-guided PCI groups (hazard ratio: 13.7% vs. 15.9%, respectively, log-rank: p = 0.67, median follow-up time: 49.0 months, IQR: 33.0-67.0). CONCLUSIONS: Use of IVUS in CTO-PCI was associated with larger stent diameter and longer stented segments. Despite more frequent use of IVUS in retrograde CTO-PCI, there was no difference in long-term adverse events between IVUS and angiography CTO-PCI groups; nevertheless, the study was not powered to assess clinical outcomes.

The new European Union (EU) law governing the regulatory approval of medical devices that entered into force in May 2017 will now take effect from 26 May 2021. Here, we consider how it will change daily practice for cardiologists, cardiac surgeons, and healthcare professionals. Clinical evidence for any high-risk device must be reported by the manufacturer in a Summary of Safety and Clinical Performance (SSCP) that will be publicly available in the European Union Database on Medical Devices (Eudamed) maintained by the European Commission; this will facilitate evidence-based choices of which devices to recommend. Hospitals must record all device implantations, and each high-risk device will be trackable by Unique Device Identification (UDI). Important new roles are envisaged for clinicians, scientists, and engineers in EU Expert Panels-in particular to scrutinize clinical data submitted by manufacturers for certain high-risk devices and the evaluations of that data made by notified bodies. They will advise manufacturers on the design of their clinical studies and recommend to regulators when new technical specifications or guidance are needed. Physicians should support post-market surveillance by reporting adverse events and by contributing to comprehensive medical device registries. A second law on In Vitro Diagnostic Medical Devices will take effect from 2022. We encourage all healthcare professionals to contribute proactively to these new systems, in order to enhance the efficacy and safety of high-risk devices and to promote equitable access to effective innovations. The European Society of Cardiology will continue to advise EU regulators on appropriate clinical evaluation of high-risk devices.

BACKGROUND: In the RE-DUAL PCI trial of patients with atrial fibrillation (AF) who underwent percutaneous coronary intervention (PCI), dabigatran dual therapy (110 or 150 mg bid, plus clopidogrel or ticagrelor) reduced International Society on Thrombosis and Haemostasis bleeding events compared with warfarin triple therapy, with noninferiority in overall thromboembolic events. This analysis assessed outcomes in relation to patient bleeding and stroke risk profiles, based on the modified HAS-BLED and CHA2DS2-VASc scores. METHODS: The primary endpoint, major bleeding event (MBE) or clinically relevant nonmajor bleeding event (CRNMBE), was compared across study arms in patients categorized by modified HAS-BLED score 0-2 or ≥3. The composite endpoint of death, thromboembolic event, and unplanned revascularization rates was compared in patients categorized by CHA2DS2-VASc score 0-1, 2, or ≥3. RESULTS: Risk of MBE or CRNMBE was lower with dabigatran dual therapy (both doses) versus warfarin triple therapy, irrespective of modified HAS-BLED category (treatment-by-subgroup interaction P-value 0.584 and 0.273 for dabigatran 110 and 150 mg dual therapy, respectively, vs warfarin). Risk of the composite thromboembolic endpoint was similar across CHA2DS2-VASc categories and consistent with overall study results (interaction P-value 0.739 and 0.075 for dabigatran 110 and 150 mg dual therapy, respectively, vs warfarin). Higher HAS-BLED scores were associated with higher risks of bleeding in AF patients after PCI in a treatment-independent analysis. CONCLUSION: Dabigatran dual therapy reduced bleeding events irrespective of bleeding risk category and demonstrated similar efficacy regardless of stroke risk category when compared with warfarin triple therapy.

Data Monitoring Committees (DMCs) play a crucial role in the conducting of clinical trials to ensure the safety of study participants and to maintain a trial's scientific integrity. Generally accepted standards exist for DMC composition and operational conduct. However, some relevant issues are not specifically addressed in current guidance documents, resulting in uncertainties regarding optimal approaches for communication between the DMC, steering committee, and sponsors, release of information, and liability protection for DMC members. The Heart Failure Association (HFA) of the European Society of Cardiology (ESC), in collaboration with the Clinical Trials Unit of the European Heart Agency (EHA) of the ESC convened a meeting of international experts in DMCs for cardiovascular and cardiometabolic clinical trials to identify specific issues and develop steps to resolve challenges faced by DMCs.The main recommendations from the meeting relate to methodological consistency, independence, managing conflicts of interest, liability protection, and training of future DMC members. This paper summarizes the key outcomes from this expert meeting, and describes the core set of activities that might be further developed and ultimately implemented by the ESC, HFA, and other interested ESC constituent bodies. The HFA will continue to work with stakeholders in cardiovascular and cardiometabolic clinical research to promote these goals.

Two proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, evolocumab and alirocumab, have recently been approved by both the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the treatment of hypercholesterolemia. These fully human monoclonal antibodies selectively block PCSK9, thus permitting the low-density lipoprotein (LDL) receptor to effectively recycle to the surface of liver cells. The administration of these antibodies leads to robust LDL cholesterol (LDL-C) lowering by 50-60% on top of maximum hypolipidemic treatment. At least 4 randomized, placebo-controlled studies are under way and will address the question of whether the administration of these PCSK9 inhibitors is associated with a significant reduction of cardiovascular events. Because of the high cost associated with the use of these medications it is very important to consider which patients may gain the most benefit, at least until the results of outcome studies are available. In this Consensus paper, 34 clinicians/scientists define 3 groups of patients that should be currently considered as candidates for the use of these novel drugs. These include: 1a. Adults with established cardiovascular disease and LDL-C≥100 mg/dL while on lifestyle modifications and maximally tolerated hypolipidemic treatment, i.e. high-intensity statin + ezetimibe, 1b. Adults with diabetes and established cardiovascular disease or chronic kidney disease or target organ damage and LDL-C ≥100 mg/dL while on lifestyle modifications and maximally tolerated hypolipidemic treatment, i.e. high-intensity statin + ezetimibe, 2. Adults with familial hypercholesterolemia (FH) without established cardiovascular disease and LDL-C ≥130 mg/dL while on lifestyle modifications and maximally tolerated hypolipidemic treatment, i.e. high-intensity statin + ezetimibe (evolocumab is also indicated in children above 12 years with homozygous FH), and 3. Adults at high or very high cardiovascular risk who are statin intolerant and have an LDL-C ≥100 and ≥130 mg/dL, respectively, while on any tolerated hypolipidemic treatment.

To conduct a systematic review of the evidence regarding the economic value of ranolazine relative to standard-of-care (SOC) for the treatment of symptomatic chronic stable angina (CSA). Electronic databases were searched using relevant keywords. The identified studies were independently reviewed by two investigators against pre-determined inclusion and exclusion criteria. Their data were extracted using a relevant form and consequently were synthesized. Studies were also evaluated using the Quality of Health Economic Studies scale. The main outcomes considered were the cost and effectiveness for each comparator and the incremental cost per quality-adjusted-life year (QALY) gained. Six studies were included in the review. Five of these assessed the cost-utility of ranolazine added to SOC, compared to SOC alone, using decision trees or Markov models whereas one was a retrospective cost evaluation study. The analysis was conducted from a payer perspective in five studies and from a societal perspective in one study with the time horizon varying between six months and a year. The incremental cost-effectiveness ratio (ICER), ranged from 4000 to 15,000 per QALY gained. Ranolazine appears to be dominant or cost-effective, mainly due to its ability to decrease angina-related hospitalizations and also due to a marginal improvement in quality of life. The acquisition cost of ranolazine was the variable with the greatest impact upon the ICER. The existing evidence, although limited, indicates that ranolazine may be a dominant or cost-effective therapy option, for the treatment of patients with symptomatic CSA. Further research is required to evaluate the cost-effectiveness of ranolazine.

Left-dominant arrhythmogenic cardiomyopathy is a subtype of arrhythmogenic right ventricular cardiomyopathy characterized by early predominant left ventricular involvement. Α 34-year-old man presented with palpitations and a history of frequent ventricular extrasystoles of both LBBB and RBBB configuration. Cardiac workup revealed repolarization abnormalities at infero-lateral leads in the absence of diagnostic structural/functional alterations or obstructive coronary artery disease. Six months later he died suddenly. Histopathology was diagnostic for arrhythmogenic right ventricular cardiomyopathy affecting predominantly the left ventricle at subepicardial/midwall myocardial layers. Thus, ventricular arrhythmias accompanied by unexplained infero-lateral T-wave inversion should warn of a possible morbid association underlying left-dominant arrhythmogenic cardiomyopathy.
