Title: TNT: New data on intensive lipid lowering in stable CHD patients


1
TNT New data on intensive lipid lowering in
stable CHD patients
2
TNT Treating to New Targets
Hypothesis Lowering LDL-C levels to well below
100 mg/dL could yield an incremental clinical
benefit Participants 10,001 patients with stable
CHD and LDL-C 130-250 mg/dL Treatments Atorvasta
tin 10 mg and 80 mg Median follow-up 4.9
years Primary outcome CHD death, MI,
resuscitation after cardiac arrest,
fatal/nonfatal stroke
