Trial Outcomes & Findings for Hypertension in Hemodialysis Patients (Aim 3) (NCT NCT00582114)

NCT ID: NCT00582114

Last Updated: 2016-01-18

Results Overview

The primary outcome of the study was the average reduction in left ventricular mass indexed for body surface area from baseline to 1 year. A mixed model was used with left ventricular mass index (LVMI) as the outcome variable. Fixed effects were indicator variables for time, treatment and their interaction. Random effect was subject and statistical inference was made using the maximum likelihood estimator. No imputation was made for missing data.

Measure
Atenolol
Atenolol: Patients will be randomized into two groups, one that is beta blocker based, the other angiotensin converting enzyme (ACE) inhibitor (lisinopril) based. Patients who are on no medications will receive atenolol 25 mg. t.i.w. or lisinopril 10 mg. t.i.w. for one month at the end of which, dose will be titrated to twice the drug doses following monthly interval to another doubling of dose. If BP is still poorly controlled felodipine will be added. Other antihypertensive therapies will be added to control home BP to \<140/90 mm Hg.
Lisinopril
Lisinopril: Patients will be randomized into two groups, one that is beta blocker based, the other ACE inhibitor (lisinopril) based. Patients who are on no medications will receive atenolol 25 mg. t.i.w. or lisinopril 10 mg. t.i.w. for one month at the end of which, dose will be titrated to twice the drug doses following monthly interval to another doubling of dose.

PRIMARY outcome

Timeframe: Baseline, 6 months, 12 months

Population: The primary outcome of the study was the average reduction in left ventricular mass indexed for body surface area from baseline to 1 year. The analysis was performed by intention to treat, if the patient received at least one dose of the randomized drug regardless of the availability of a post-baseline echocardiogram.

The primary outcome of the study was the average reduction in left ventricular mass indexed for body surface area from baseline to 1 year. A mixed model was used with left ventricular mass index (LVMI) as the outcome variable. Fixed effects were indicator variables for time, treatment and their interaction. Random effect was subject and statistical inference was made using the maximum likelihood estimator. No imputation was made for missing data.

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 yr

Cardiovascular events were counted by subject and included the following: myocardial infarction (MI), stroke, hospitalization for congestive heart failure (CHF), hospitalized angina, arrhythmias, cardiac arrest, coronary revascularization and heart valve replacement. Adverse events reported are those during the course of 12 months of participation in the trial. All serious adverse events were adjudicated by R.A. and A.D.S. who were masked to the drug assignment at the time of adjudication. The duration of participation in the study per subject, which according to the trial design could be up to 12 months, was determined. The cardiovascular event rate was calculated by treatment group assignment. Incidence rate ratio (IRR) by treatment was then determined along with the 95% confidence intervals (95% CIs). As a post hoc analysis, we also determined the narrower definition of cardiovascular events per group that included MI, stroke, CHF, or cardiovascular death.
