Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
Effect of Aliskiren on Albuminuria as Measured by Urinary Albumin Excretion Rate (UAER)
Prazo: 26 weeks
Two 24-hour collections of urine were to be made at each study visit. The arithmetic mean of the two collections were planned to be used in the calculation of summary statistics and the statistical analyses.
26 weeks
Effect of Aliskiren on Albuminuria as Measured by Creatinine Indexed Albumin

26 weeks

Medidas de resultados secundários

Medida de resultado
Descrição da medida
Prazo
Mean Sitting Systolic Blood Pressure (msSBP)
Prazo: 26 weeks
At study entry, blood pressure (BP) was measured in both arms. If there was a clinically relevant difference in readings between arms (≥ 10 mmHg in systolic BP and/or ≥ 5 mmHg in diastolic BP), the arm with higher BP reading was used. If there was no clinically significant difference between arms, the non-dominant arm was used through out study. Systolic blood pressure were assessed after the patient rested quietly in the sitting position for at least 3 minutes. For each sitting assessment, blood pressure was assessed at least 3 times. From these assessments, msSBP was calculated. All BP measurements were to be performed on the same arm.
26 weeks
Mean Sitting Diastolic Blood Pressure (msDBP)
Prazo: 26 weeks
At study entry, blood pressure (BP) was measured in both arms. If there was a clinically relevant difference in readings between arms (≥ 10 mmHg in systolic BP and/or ≥ 5 mmHg in diastolic BP), the arm with higher BP reading was used. If there was no clinically significant difference between arms, the non-dominant arm was used through out study. Diastolic blood pressure were assessed after the patient rested quietly in the sitting position for at least 3 minutes. For each sitting assessment, blood pressure was assessed at least 3 times. From these assessments, msDBP was calculated. All BP measurements were to be performed on the same arm.
26 weeks
Mean Glomerular Filtration Rate (GFR) as Measurement of Renal Function
Prazo: 26 weeks
All patients had to visit the main center for renal function measurements. The measurements were performed using the constant infusion method with I-iothalamate (IOT) and I-hippuran. GFR was calculated as the urinary clearance of IOT.
26 weeks
Mean Effective Renal Plasma Flow (ERPF) as One of Hemodynamic Assessments
Prazo: 26 weeks
26 weeks
Percentage of Renal Filtration Fraction (RFF) as One of Hemodynamic Assessments
Prazo: 26 weeks
26 weeks
Mean Extracellular Volume (ECV) as One of Hemodynamic Assessments
Prazo: 26 weeks
26 weeks
Plasma Rennin Activity (PRA)
Prazo: Baseline to week 26
Blood biomarkers were obtained from blood samples in all patients at the time points such as baseline, week 6, week 12, week 18 and week 26. Plasma PRA is a direct measure of the formation of Ang I in the plasma.
Baseline to week 26
Plasma Rennin Concentration (PRC)
Prazo: Baseline to week 26
Blood biomarkers were obtained from blood samples in all patients at the time points such as baseline, week 6, week 12, week 18 and week 26. PRC measures the concentration of immunoactive renin in the plasma.
Baseline to week 26
Number of Participants With Adverse Events, Serious Adverse Events and Death as Assessment of Safety and Tolerability of Aliskiren Added to Ramipril
Prazo: 26 weeks
