The Potential Value of Near Patient Platelet Function Testing in PCI: Randomised Comparison of 600 mg versus 900 mg Clopidogrel Loading Doses

Table 1

The %PIn, %CIn, and % Change in PRU of (a) all healthy volunteers 6 hours post 600 mg clopidogrel, (b) poor responders to 600 mg: 6 hours post 600 mg clopidogrel, (c) poor responders to 600 mg: 6 hours post 900 mg clopidogrel. Data presented as mean $\pm$ 95% confidence interval of the mean (numbers analysed).

%CIn	$37.7\pm 15.9$ (28)	$-15.1\pm 21.6$ (9)	$22.9\pm 15.9$ (9)	.01
% Change in PRU	$59.9\pm 10.1$ (28)	$20.1\pm 8.2$ (5)	$45.0\pm 16.3$ (5)	.03
