whether a DOUBLE dose of clopidogrel (Plavix) prevents more cardiovascular events in stent patients

Experts are debating whether a DOUBLE dose of clopidogrel (Plavix) prevents more cardiovascular events in stent patients.

Up to 25% of patients don't respond well to clopidogrel's antiplatelet effects...and are at higher risk for a cardiac event.

So some prescribers order platelet function tests to identify patients who have high platelet activity despite clopidogrel therapy.
