TNT: New data on intensive lipid lowering in stable CHD patients
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: Atorvastatin 10 mg and 80 mg Median follow-up: 4.9 years Primary outcome: CHD death, MI, resuscitation after cardiac arrest, fatal/nonfatal stroke TNT: Treating to New Targets LaRosa JC et al. N Engl J Med. 2005;352.
