12 Should our guidelines for vascular disease prevention change?
Inflammation, hsCRP, and Vascular Prevention Is there evidence that individuals with elevated levels of the inflammatory biomarker hsCRP are at high vascular risk even when other risk factors are acceptable? Is there evidence that individuals identified at increased risk due to inflammation benefit from a therapy they otherwise would not have received? Should our guidelines for vascular disease prevention change?

17 JUPITER Why Consider Statins for Low LDL, high hsCRP Patients?

Thus, a large-scale randomized trial of statin therapy was needed to directly test this hypotheses. New Engl J Med 2001;344:

32 Should our guidelines for vascular disease prevention change?
Inflammation, hsCRP, and Vascular Prevention Is there evidence that individuals with elevated levels of the inflammatory biomarker hsCRP are at high vascular risk even when other risk factors are acceptable? Is there evidence that individuals identified at increased risk due to inflammation benefit from a therapy they otherwise would not have received? Should our guidelines for vascular disease prevention change?

However, they ALL have hsCRP > 2 mg/L.

35 US FDA APPROVES NEW INDICATION FOR CRESTOR (ROSUVASTATIN CALCIUM)
Approval based on JUPITER study which evaluated CRESTOR in a previously unstudied population For immediate release: 9 February 2009 The US Food and Drug Administration (FDA) has approved CRESTOR (rosuvastatin calcium) to reduce the risk of stroke, myocardial infarction (heart attack) and arterial revascularization procedures in individuals without clinically evident coronary heart disease but with an increased risk of cardiovascular disease (CVD) based on age (men ≥50 and women ≥60), high-sensitivity C-reactive protein (hsCRP) ≥ 2 mg/L, and the presence of at least one additional CVD risk factor, such as hypertension, low HDL-C, smoking, or a family history of premature coronary heart disease.

39 Public Health Implications
JUPITER Public Health Implications Exercise, diet, and smoking cessation remain the first interventions for those with elevated LDLC or hsCRP. However, application of the simple screening and treatment strategy tested in the JUPITER trial over a five-year period could conservatively prevent more than 250,000 heart attacks, strokes, revascularization procedures, and cardiovascular deaths in the United States alone. Simplified guidelines that advocate combined lifestyle and pharmacologic therapy in those groups where trial evidence clearly supports a net benefit have the potential to greatly improve patient care and public health. With thanks to the 17,802 patients and the >1,000 physicians worldwide for their effort and commitment to the JUPITER trial program.

40 Public Health Implications
JUPITER Public Health Implications Low LDL, Low hsCRP Low LDL, High hsCRP Low LDL, Low hsCRP Low LDL, High hsCRP [A] [B] 0.5 1.0 2.0 New Engl J Med 2001;344: 0.5 1.0 2.0 RR Statin Effective Statin Not Effective We must rely on hard clinical trial evidence to inform clinical guidelines and compute cost-effectiveness. Making assumptions about the net benefit to risk ratio for statins in specific patient groups where contradicting data exist (such as those with low LDLC and low hsCRP) is unwarranted and will lead to claims that we are promoting pharmaceutical use in the absence of evidence.
