A Review of the Key Clinical Trials of 2014.

Abstract

IntroductionOver the last year, multiple, potentially practice-changing, cardiology trials or studies have been published or presented at international meetings including the American College of Cardiology, European Association for Percutaneous Cardiovascular Interventions, European Society of Cardiology, Transcatheter Cardiovascular Therapeutics, Heart Failure Congress, Heart Rhythm Society, Heart Failure Society of America, American Society of Hypertension and the American Heart Association.MethodsClinical trial results presented at major cardiology conferences during 2014 were reviewed by the authors. Search terms included heart failure (HF), acute coronary syndrome, stable coronary disease, interventional cardiology, atrial fibrillation, electrophysiology and coronary prevention. Selection criteria were trials of broad relevance to the cardiology community, those with potential to change current practice and those with potential to guide further phase III research.ResultsIn this paper, the authors describe and place in clinical context, new HF, data including neprilysin inhibitors, intravenous ferric carboxymaltose, potassium-absorbing compounds, quadripolar leads for cardiac resynchronization therapy and intraventricular device intervention. New trial data are also described for acute coronary syndromes (clopidogrel, prasugrel, ticagrelor), stable coronary artery disease (ivabradine), percutaneous coronary intervention (the role of thrombectomy or treatment of non-culprit lesions during primary intervention, pressure wire studies and outcomes of new stent designs), transcatheter aortic valve intervention data, atrial fibrillation (anticoagulation and direct current cardioversion), electrophysiology (leadless pacemaker devices, use of quinidine in Brugada syndrome) and coronary prevention (landmark Ezetimibe outcome data, PCSK9 clinical trials, childhood prevalence of hypertension, renal denervation for resistant hypertension and the role of cardiac computerized tomography in cardiovascular screening).ConclusionThis paper summarizes key clinical trials during 2014 and should be of practical interest to clinicians and cardiology researchers.Electronic supplementary materialThe online version of this article (doi:10.1007/s40119-015-0036-0) contains supplementary material, which is available to authorized users.
