Arrhythmia care in ESC member countries: The 2025 ESC-EHRA atlas on heart rhythm disorders

The ESC-EHRA Atlas on Heart Rhythm Disorders was developed to comprehensively map arrhythmia care across the European Society of Cardiology (ESC) member countries. A survey of National Cardiac Societies, Working Groups, and other EHRA partners in ESC member countries was conducted to gather data from 2023 or the most recently available year on arrhythmia care organization and delivery. In total, 51 ESC member countries actively participated in the study, with a survey completeness rate of 91%. The median number of hospitals performing EP or CIED procedures was 3.3 per million people. The annual median numbers of ablation procedures for heart rhythm disorders, atrial fibrillation, and supraventricular tachycardia per million people were 432, 151, and 136, respectively. The annual median numbers of pacemakers, implantable cardioverter-defibrillators (ICD), and cardiac resynchronization therapy cardioverter-defibrillator (CRT-D) implantations per million people were 739, 195, and 54, respectively. The median number of hospitals performing remote monitoring of CIEDs per million people was 0.5, though this service was unavailable in 15 countries. Two main universal issues emerged among the obstacles to guideline implementation: a lack of heart rhythm allied professionals and general dissatisfaction with the country's reimbursement system. The first edition of the ESC-EHRA Atlas presents up-to-date information on arrhythmia care organization and delivery among ESC member countries and highlights significant discrepancies in patients' access to ESC-guideline-recommended therapies

Recent findings on the health effects of omega-3 fatty acids and statins, and their interactions: do statins inhibit omega-3?

<p>Abstract</p> <p>Early randomized controlled trials (RCTs) demonstrated the health benefits of omega-3 fatty acids (n-3), whereas recent RCTs were negative. We now address the issue, focusing on the temporal changes having occurred: most patients in recent RCTs are no longer n-3 deficient and the vast majority are now treated with statins. Recent RCTs testing n-3 against arrhythmias suggest that n-3 reduce the risk only in patients not taking a statin. Other recent RCTs in secondary prevention were negative although, in a <it>post-hoc </it>analysis separating statin users and non-users, non-significant protection of n-3 was observed among statin non-users whereas statin users had no effect. Recent RCTs testing statins - after the implementation of the New Clinical Trial Regulation in 2007 - are negative (or flawed) suggesting that the lack of effect of n-3 cannot be attributed to a parallel protection by statins. Finally, statins favor the metabolism of omega-6 fatty acids (n-6), which in turn inhibits n-3 and, contrary to n-3, they increase insulin resistance and the risk of diabetes. Thus, n-3 and statins are counteractive at several levels and statins appear to inhibit n-3.</p
