Design outcomes

Primary

MeasureTime frameDescription
Change in Left Ventricular Mass Index (LVMI) From Baseline to End of Study (Week 36)Baseline to end of study (Week 36)Left ventricular mass index (LVMI) was measured by magnetic resonance imaging (MRI). An increase in LVMI indicates hypertrophy of the left ventricle. This could be a normal reversible response to cardiovascular conditioning (athletic heart) or an abnormal irreversible response to chronically increased volume load (preload) or increased pressure load (afterload). Thickening of the ventricular muscle results in increased left ventricular pressure, increased end-systolic volume, and decreased end-diastolic volume, causing an overall reduction in cardiac output.

Change in Left Ventricular Mass Index (LVMI) From Baseline to End of Study (Week 36)

Left ventricular mass index (LVMI) was measured by magnetic resonance imaging (MRI). An increase in LVMI indicates hypertrophy of the left ventricle. This could be a normal reversible response to cardiovascular conditioning (athletic heart) or an abnormal irreversible response to chronically increased volume load (preload) or increased pressure load (afterload). Thickening of the ventricular muscle results in increased left ventricular pressure, increased end-systolic volume, and decreased end-diastolic volume, causing an overall reduction in cardiac output.

Time frame: Baseline to end of study (Week 36)

Population: Efficacy population: All patients who had a baseline measurement and at least one post-baseline efficacy variable measurement patients and who had been treated for at least 28 weeks and had evaluable MRI assessments both at baseline and at the end of the study.

Change From Baseline in Mean 24-hour Ambulatory Diastolic and Systolic Blood Pressure From Baseline to the End of the Study (Week 36)

Two 24-hour ambulatory blood pressure monitoring (ABPM) evaluations were performed, one at baseline and one at the end of the study. For each evaluation, the ABPM device was attached to the non-dominant arm of the patient. A correlation was made between the ABPM device readings and measurements taken with a mercury sphygmomanometer and stethoscope. Following the correlation procedure, blood pressure was measured at study specified intervals.

Time frame: Baseline the end of study (Week 36)
