Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: We aim to determine whether one of the most commonly prescribed drugs for osteoporosis; bisphosphonates; also confer beneficial cardiovascular effects through effects on the cholesterol synthesis pathway;Secondary Objective: This study aims to clarify if impaired endothelial function; an important step in coronary heart disease; contributes to increased cardiovascular risk in postmenopausal women with osteoporosis;Primary end point(s): Primary outcomes: significant increase in platelet NO bioavailability and decrease in O2- production. Secondary outcomes: increased vascular reactivity and endothelium dependant vasodilatation, down regulation of Rac and Rho activity, NO synthase and NAD(P)H oxidase: reduced platelet activation, and reduction in serial measurements of bone markers | — |
