Use of Homeopathy for Prevention of Atrial Fibrillation in Patients After Aortocoronary Bypass and Heartvalve Surgery With Heart-lung Machine
Summary
After heart surgery, about 30% of patients suffer from atrial fibrillation. Patients are randomized into two groups receiving either potentized Strychnos Nux vomica or placebo under double blind conditions. Postoperatively, ECGs are done to monitor cardiac rhythm.

Medical and Biotech [MESH] Definitions
Atrial Flutter
Rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. Unlike ATRIAL FIBRILLATION which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. As in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (HEART VENTRICLES).
Therapeutic Misconception
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
Digoxin
A cardiotonic glycoside obtained mainly from Digitalis lanata; it consists of three sugars and the aglycone DIGOXIGENIN. Digoxin has positive inotropic and negative chronotropic activity. It is used to control ventricular rate in ATRIAL FIBRILLATION and in the management of congestive heart failure with atrial fibrillation. Its use in congestive heart failure and sinus rhythm is less certain. The margin between toxic and therapeutic doses is small. (From Martindale, The Extra Pharmacopoeia, 30th ed, p666)
Placebo Effect
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
Warfarin
An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.
Clinical Trials
A study to test the safety, tolerability, and efficacy of 4 regimens of vaniprevir + Peg-IFN and RBV as compared to placebo + Peg-IFN and RBV.
Sitagliptin vs Glipizide in Patients With Type 2 Diabetes Mellitus and Chronic Renal Insufficiency
The purpose of the study is to compare how sitagliptin and glipizide lower blood glucose levels in patients with moderate and severe renal insufficiency.
MK0518 in the Treatment of HIV-Infected Patients Switched From a Protease Inhibitor Regimen
The purpose of this study is to investigate the efficacy, safety, and tolerability of an investigational treatment for patients with Human Immunodeficiency Virus (HIV).
A Multiple Dose Study of MK3614
This study will evaluate if MK3614, given in multiple rising doses, is safe and tolerated in male subjects with mild to moderate hypertension.
Montelukast Asthmatic Smoker Study
This is a multicenter study to evaluate the efficacy and safety of MK0476 versus placebo in patients with chronic asthma who actively smoke cigarettes.
