Comprehensive risk reduction in patients with atrial fibrillation: emerging diagnostic and therapeutic options-a report from the 3rd Atrial Fibrillation Competence NETwork/European Heart Rhythm Association consensus conference

While management of atrial fibrillation (AF) patients is improved by guideline-conform application of anticoagulant therapy, rate control, rhythm control, and therapy of accompanying heart disease, the morbidity and mortality associated with AF remain unacceptably high. This paper describes the proceedings of the 3rd Atrial Fibrillation NETwork (AFNET)/European Heart Rhythm Association (EHRA) consensus conference that convened over 60 scientists and representatives from industry to jointly discuss emerging therapeutic and diagnostic improvements to achieve better management of AF patients. The paper covers four chapters: (i) risk factors and risk markers for AF; (ii) pathophysiological classification of AF; (iii) relevance of monitored AF duration for AF-related outcomes; and (iv) perspectives and needs for implementing better antithrombotic therapy. Relevant published literature for each section is covered, and suggestions for the improvement of management in each area are put forward. Combined, the propositions formulate a perspective to implement comprehensive management in AF.

Suppression of paroxysmal atrial tachyarrhythmias - results of the SOPAT trial

AIM The indication to treat paroxysmal atrial fibrillation (PAF) is controversial. The Suppression of Paroxysmal Atrial Tachyarrhythmias (SOPAT) trial was designed to answer the following questions: (1) What is the average rate of spontaneous events of symptomatic PAF with and without anti-arrhythmic medication? (2) what is the prevalence of severe side-effects? and (3) is the fixed combination of Quinidine + Verapamil inferior to the efficacy of sotalol or not? METHODS AND RESULTS Within 60 months 172 centres in Germany, Poland, and The Slovak Republic prospectively enrolled 1033 patients (mean age 60 years, 62% male) with documented frequent episodes of symptomatic PAF. Patients were randomised to either Quinidine + Verapamil 480/240 mg/d (high dose; 263 patients), Quinidine + Verapamil 320/160 mg/d (low dose; 255 patients), Sotalol 320 mg/d (264 patients) or placebo (251 patients), of which 1012 patients entered the intention-to-treat analysis. The primary endpoint was the time to first recurrence of symptomatic PAF or premature discontinuation. Secondary outcome parameters were the total number of symptomatic episodes and tolerability of the tested drugs. Patients were followed for a period of up to 12 months by daily and symptom-triggered trans-telephonic ECG-monitoring (Tele-ECG). The mean time under treatment was 233 +/- 152 days. Regarding the primary endpoint, all active treatments were superior to placebo and not different from each other. A total of 756 patients reached the primary endpoint within 105.7 +/- 8.7 d (mean +/- SEM) in the placebo group, vs. Quinidine + Verapamil (high dose) (150.4 +/- 10 d, p = 0.0061), vs. Quinidine + Verapamil (low dose) (148.9 +/- 10.6 d, p = 0.0006), vs. Sotalol (145.6 +/- 93 d, p = 0.0007). All three treatments were also effective in the reduction of AF burden (days with symptomatic AF [%] mean +/- SD, p vs. placebo): Quinidine + Verapamil (high dose) (3.4 +/- 12, p = 0.0001), Quinidine + Verapamil (low dose) (4.5 +/- 12.3, p = 0.008) and Sotalol (2.9 +/- 6.5, p = 0.026) compared to placebo (6.1 +/- 13.5). A total of four deaths, 13 syncopes, and one ventricular tachycardia (VT) occurred during the active study period, of which one death and one VT were related to Quinidine/Verapamil. CONCLUSION Taken together, anti-arrhythmic therapy with the fixed combination of Quinidine + Verapamil is as effective as Sotalol in the reduction of the recurrence rate of symptomatic PAF with a low but definite risk of severe side-effects.

Long-term clinical effects of ventricular pacing reduction with a changeover mode to minimize ventricular pacing in a general pacemaker population

Abstract Aim Right ventricular pacing (VP) has been hypothesized to increase the risk in heart failure (HF) and atrial fibrillation (AF). The ANSWER study evaluated, whether an AAI-DDD changeover mode to minimize VP (SafeR) improves outcome compared with DDD in a general dual-chamber pacemaker population. Methods and results ANSWER was a randomized controlled multicentre trial assessing SafeR vs. standard DDD in sinus node disease (SND) or AV block (AVB) patients. After a 1-month run-in period, they were randomized (1 : 1) and followed for 3 years. Pre-specified co-primary end-points were VP and the composite of hospitalization for HF, AF, or cardioversion. Pre-specified secondary end-points were cardiac death or HF hospitalizations and cardiovascular hospitalizations. ANSWER enrolled 650 patients (52.0% SND, 48% AVB) at 43 European centres and randomized in SafeR (n = 314) or DDD (n = 318). The SafeR mode showed a significant decrease in VP compared with DDD (11.5 vs. 93.6%, P < 0.0001 at 3 years). Deaths and syncope did not differ between randomization arms. No significant difference between groups [HR = 0.78; 95% CI (0.48–1.25); P = 0.30] was found in the time to event of the co-primary composite of hospitalization for HF, AF, or cardioversion, nor in the individual components. SafeR showed a 51% risk reduction (RR) in experiencing cardiac death or HF hospitalization [HR = 0.49; 95% CI (0.27–0.90); P = 0.02] and 30% RR in experiencing cardiovascular hospitalizations [HR = 0.70; 95% CI (0.49–1.00); P = 0.05]. Conclusion SafeR safely and significantly reduced VP in a general pacemaker population though had no effect on hospitalization for HF, AF, or cardioversion, when compared with DDD.

Is Right Ventricular Outflow Tract Pacing an Alternative to Left Ventricular/Biventricular Pacing?

The right ventricular apex has been used as the traditional pacing site since the development of transvenous pacing in 1959. Some studies suggest that pacing the right ventricular apex may cause remodeling and is harmful. In the past decade, there have been a multitude of studies of the hemodynamic, electrophysiological, electrocardiographic, and clinical effects of ventricular pacing at other sites. Pacing of the left ventricle singly or with biventricular pacing has emerged as an effective and safe therapy for moderate to severe congestive heart failure in patients with prolonged QRS complexes. Studies of alternate right ventricular sites, like the right ventricular outflow tract, have given mixed results. Not all patients can be treated with left ventricular pacing, which is a time‐consuming and difficult procedure. Right ventricular pacing is easier and less expensive than left ventricular pacing and further study of additional right ventricular sites seems warranted. (PACE 2004; 27[Pt. II]:871–877)

Hypertension and cardiac arrhythmias: A consensus document from the European Heart Rhythm Association (EHRA) and ESC Council on Hypertension, endorsed by the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS) and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE)

Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e.g. hypokalaemia, hypomagnesemia), further contributing to arrhythmias, whereas effective control of blood pressure may prevent the development of the arrhythmias such as AF. In recognizing this close relationship between hypertension and arrhythmias, the European Heart Rhythm Association (EHRA) and the European Society of Cardiology (ESC) Council on Hypertension convened a Task Force, with representation from the Heart Rhythm Society (HRS), Asia-Pacific Heart Rhythm Society (APHRS), and Sociedad Latinoamericana de Estimulación Cardíaca y Electrofisiología (SOLEACE), with the remit to comprehensively review the available evidence to publish a joint consensus document on hypertension and cardiac arrhythmias, and to provide up-to-date consensus recommendations for use in clinical practice. The ultimate judgment regarding care of a particular patient must be made by the healthcare provider and the patient in light of all of the circumstances presented by that patient.

Summary statement: EHRA summit 2010 with the participation of Central-Eastern European countries: 'ICD for Life' Initiative--fighting against sudden cardiac death in emerging economies.

The conference of the ‘Implantable Cardioverter Defibrillator for Life’ Initiative—Fighting against Sudden Cardiac Death in Emerging Economies was jointly organized by the European Heart Rhythm Association and the Hungarian Society of Cardiology. The aim of the summit was to demonstrate the benefit and efficacy of the prevention of sudden cardiac death (SCD). Sudden cardiac death is responsible for a significant number of deaths at an annual level and it is the leading cause of death in industrial countries. Many arrhythmias could be treated by means of device therapy and this would also reduce the death rates. The target of the summit was to build bridges between medical, political, and industrial sectors to procure greater political and economic care and support for the primary and secondary prevention of sudden cardiac death, heart failure, and arrhythmias. The number of implantable cardioverter-defibrillator (ICD) implantations has increased enormously in the recent years based on the proven efficacy of implantable devices in the treatment of heart failure and heart rhythm disturbances. However, many patients with high risk of SCD still do not undergo ICD implantation. The reason is partly economic, and partly due to the lack of public awareness and the lack of qualified specialists. The conference emphasized that both the theoretical background of device therapy—professional recommendations, choice of implantable devices, programming, and problem solving—and the practical education of implantation methods are important to increase the implantation rates. The paradoxity of the effort to reduce SCD in economies in transition is that there is a high prevalence of high-risk patients on one side and actual implant rates both for primary and secondary prevention are disproportially low. The summit attempted to reflect regional disparities, their political, economic, financial, and, last but not least, educational background through a series of lectures held by the representatives of countries …

Roadmap for cardiovascular education across the European Society of Cardiology: inspiring better knowledge and skills, now and for the future

AIMS The provision of high-quality education allows the European Society of Cardiology (ESC) to achieve its mission of better cardiovascular practice and provides an essential component of translating new evidence to improve outcomes. METHODS AND RESULTS The 4th ESC Education Conference, held in Sophia Antipolis (December 2016), brought together ESC education leaders, National Directors of Training of 43 ESC countries, and representatives of the ESC Young Community. Integrating national descriptions of education and cardiology training, we discussed innovative pathways to further improve knowledge and skills across different training programmes and health care systems. We developed an ESC roadmap supporting better cardiology training and continued medical education (CME), noting: (i) The ESC provides an excellent framework for unbiased and up-to-date cardiovascular education in close cooperation with its National Societies. (ii) The ESC should support the harmonization of cardiology training, curriculum development, and professional dialogue and mentorship. (iii) ESC congresses are an essential forum to learn and discuss the latest developments in cardiovascular medicine. (iv) The ESC should create a unified, interactive educational platform for cardiology training and continued cardiovascular education combining Webinars, eLearning Courses, Clinical Cases, and other educational programmes, along with ESC Congress content, Practice Guidelines and the next ESC Textbook of Cardiovascular Medicine. (v) ESC-delivered online education should be integrated into National and regional cardiology training and CME programmes. CONCLUSION These recommendations support the ESC to deliver excellent and comprehensive cardiovascular education for the next generation of specialists. Teamwork between international, national and local partners is essential to achieve this objective.
