title: American Heart Association scientific sessions.
abstract: The Annual Scientific Sessions of the American Heart Association is the leading scientific conference in the cardiovascular field, both for basic and clinical research in cardiology and related disclipines. This report covers the outcome of major clinical trials that were presented in the 'late-breaking' clinical trial sessions. The Valsartan in Acute Myocardial Infarction Trial (VALIANT) investigated the angiotensin receptor blocker valsartan, the angiotensin-converting enzyme inhibitor captopril, and their combination in 14,703 survivors of an acute myocardial infarction with a reduced left ventricular ejection fraction on clinical outcome. The study demonstrated that valsartan and captopril where equally effective, whereas the combination was associated with an increased risk of side effects without further benefit. VALIANT is a landmark trial because it was the first large study that compared the combination of an angiotensin receptor blocker with an angiotensin-converting enzyme inhibitor in the setting of acute myocardial infarction. Other trials that will be summarised in this report are the Na + /H + Exchange Inhibition to Prevent Coronary Events in Acute Cardiac Conditions Trial (EXPEDITION; cariporide in coronary artery bypass graft surgery), the Reversal of Atherosclerosis with Aggressive Lipid Lowering Trial (REVERSAL; atorvastatin and pravastatin for atherosclerosis reversal), the Stroke Prevention Using an Oral Thrombin Inhibitor in Atrial Fibrillation V (SPORTIF V; ximelagatran and warfarin for stroke prevention in atrial fibrillation), the Prophylactic Amiodarone for the Prevention of Arrhythmias that Begin Early After Revascularisation (PAPABEAR; amiodarone for the prevention of postoperative atrial fibrillation), the Acute and Chronic Therapeutic Impact of a Vasopressin 2 Antagonist in Congestive Heart Failure (ACTIV in CHF; vasopressin 2 antagonist tolvaptan in congestive heart failure) and Prevention of Renal and Vascular Endstage Disease Intervention Trial (PREVEND IT; fosinopril and pravastatin in microalbuminuric subjects without hypertension or hypercholesterolemia).
