Role of ALiskiren, a Direct Renin Inhibitor, in Preventing Atrial Fibrillation in Patients With a Pacemaker; RALF.

2016-09-21 20:23:22 | BioPortfolio

Summary

The aim of the study is to find out whether aliskiren reduces atrial fibrillation burden measured with a pacemaker device

Description

The aim of the study is to find out the effect of a direct renin inhibitor, aliskiren, in reduction of AF with patients who have a pacemaker due to sinus node disease and paroxysmal atrial fibrillation.

Hypothesis is that there is a possibility to reduce atrial remodeling due to AF and also to enhance atrial reverse remodeling with aliskiren. The effect of aliskiren to total AF burden will be evaluated from the pacemaker's memory storage.

The main purpose of the study is to find new and safe drug treatments targeting to reduce AF recurrences and related complications in pacemaker patients. Also the aim is to evaluate the feasibility of a modern and highly sophisticated pacemaker system in the evaluation of drug treatment with AF reduction.

Hemodynamic Effects of Aliskiren Compared to Captopril on the Kidney in Healthy Volunteers on a Low- and High- Sodium Diet

This study will measure the effects of different doses of aliskiren on kidney blood flow and function in healthy adults and determine how salt intake affects the response to aliskiren.

Prevention of AtriaL Fibrillation After Cardiac Surgery

The purpose of this study is to determine if preforming a posterior left pericardiotomy prevents atrial fibrillation after cardiac surgery.

Aliskiren and the Calcium Channel Blocker Amlodipine Combination as an Initial Treatment Strategy for Hypertension

This study will assess the safety and efficacy of combination aliskiren/amlodipine in patients with hypertension not adequately controlled with amlodipine alone

Medical and Biotech [MESH] Definitions

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).

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)

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.

A type of cardiac arrhythmia with premature atrial contractions or beats caused by signals originating from ectopic atrial sites. The ectopic signals may or may not conduct to the HEART VENTRICLES. Atrial premature complexes are characterized by premature P waves on ECG which are different in configuration from the P waves generated by the normal pacemaker complex in the SINOATRIAL NODE.

Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
