Measuring the Activated Clotting Time in patients receiving unfractionated heparin prior to coronary angiography and intervention. A single-centre validation study comparing different blood sampling sites

This study aims at establishing the influence of sampling site on the variability of ACT measurement at the end of coronary angiography or PCI.

A placebo-controlled, double-blind, randomized trial to compare the effect of treatment on plaque burden as determined by intravascular ultrasound and to evaluate the efficacy, pharmacokinetics, safety, and tolerability of MDCO-216 given as multiple weekly infusions in subjects with a recent acute coronary syndrome.

Primary ObjectivesTo evaluate the effect of MDCO-216 treatment on the change in PAV of a target coronary artery as measured by IVUS imaging following five weekly infusions of MDCO-216 (20 mg/kg) compared with placebo in subjects with a recent ACS.…

Role of different phosphate binders on absorption of vitamin K, metabolism of matrix *-carboxy-glutamaat (Gla) proteïne (MGP).

This research will have as aim to look at progression or decrease of vascular calcification in dialysis population with use of different phosphate binders. There is a possibility that differect phosphate binders bind vitamin K in a different way in…

Pressure-Flow Measurements Directly after Primary PCI to Predict Late Occurrence of Microvascular Obstruction

In the present study we aim to determine the value of microvascular resistance measurements in the acute setting to predict the occurrence of MVO in the following days, using the combined pressure-flow wire. Therefore patients with an acute MI will…
