Valsartan to Prevent Left Ventricle Remodeling in Pacemaker Patients

April 10, 2023 updated by: Andrzej Tomasik MD PhD FESC, Medical University of Silesia

Randomized, Placebo Controlled Blinded Study to Assess the Efficacy of Valsartan to Prevent Left Ventricle Remodeling in Patients With Dual Chamber Pacemaker

Dual chamber pacing is known to induce left ventricle remodeling and may eventually lead to heart failure. The investigators aim to test hypothesis that valsartan started immediately after dual chamber pacemaker implantation will prevent left ventricle remodeling in twelve months long follow up in comparison with placebo. Echocardiographic assessment of left ventricle remodeling will be correlated with plasma activity of matrix metalloproteinases and their tissue inhibitors, indices of functional capacity such as plasma level of NTproBNP and distance in meters during six minute walking test.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
