ALiskiren or Losartan Effects on bioMARKers of Myocardial Remodeling

Novartis Pharmaceuticals74 enrolled

Overview

The purpose of this study is to assess efficacy of aliskiren for reducing circulating levels of biomarkers of left ventricular (LV) remodeling associated with LV hypertrophy (LVH) in hypertensive patients.

Blood pressure was measured 10 weeks after starting treatment (visit 3). All patients who did not achieve the required blood pressure (\<140/90 mmHg) after 8 weeks of treatment at the maximum doses of study medication were given 5 mg of amlodipine in addition to the study medication in order to reach the required BP (\<140/90 mmHg). The patient's blood pressure was assessed at visit 4 (week 18) and if it was still not at the required level (\<140/90 mmHg), the dose of amlodipine was increased to 10 mg. Blood pressure was again assessed at visit 5 (week 26) and if the required values had not been reached (\<140/90 mmHg), a 12.5 mg dose of hydrochlorothiazide (HCTZ) was prescribed

Amlodipine 5mg was given to patients who did not achieve the required blood pressure (\<140/90 mmHg) after 8 weeks (visit 3)of treatment at the maximum doses of study medication in addition to the study medication in order to reach the required BP. at visit 4 (week 18) the dose of amlodipine was increased to 10mg if the required level (\<140/90 mmHg) was still not achieved.

Outcomes

Primary Outcomes

Change From Baseline in C-terminal Propeptide of Procollagen Type I (PICP)

PICP is a measure of blood concentration of procollagen I carboxy-terminal propeptide (PICP), a peptide released from the myocardium when procollagen is converted to type I collagen. This biomarker exhibits good specificity and sensitivity for identifying myocardial fibrosis in hypertension.

Time frame: Baseline, Week 36

Secondary Outcomes

Change From Baseline in Biomarkers in Heart Disease

The plasma level of biomarkers parameters used to measure improvement in left ventricular (LV) function or reduction in left ventricular mass index (LVMI). The following biomarkers were analyzed: cardiotrophin-1 (CT-1), matrix metalloproteinase-1 (MMP-1); tissue inhibitor of MMPs (TIMP-1); annexin A5 (AnxA5); N-terminal prohormone of B-type natriuretic peptide (NT-proBNP)

Time frame: Baseline, Week 36

Change From Baseline in Biomarker Such as Aldosterone (Aldo) in Heart Disease

The plasma level of biomarker parameter (aldosterone (Aldo)) used to measure improvement in left ventricular (LV) function or reduction in left ventricular mass index (LVMI)

Time frame: Baseline, Week 36

Change From Baseline in Left Ventricular (LV) Function, LV End-diastolic Volume by Simpson's Rule, and LV End-systolic Volume by Simpson's Rule

Reductions in the following measurements were analysed between the baseline visit and the final visit: LV end-diastolic volume by Simpson's rule, and LV end-systolic volume by Simpson's rule

Time frame: Baseline, Week 36

Change From Baseline in Left Ventricular (LV) Function, LV Ejection Fraction (Teicholz), and LV Ejection Fraction (Simpson)

Reductions in the following measurements were analysed between the baseline visit and the final visit: LV ejection fraction (Teicholz), and LV ejection fraction (Simpson)

HCTZ 12.5mg was prescribed at visit 5 (week 26) if the required values (\<140/90 mmHg) had not been reached.
