This finding may prompt cardiologists to rethink their approach to stent placement and consider alternative treatments to lower this risk.
Researchers at Northwestern University report a rare but potentially fatal blood disease known as thrombotic thrombocytopenic purpura (TTP) associated with clopidogrel use. The disorder causes mass destruction of blood platelets, anemia, and other severe symptoms.
