Reduced Coronary Events in Simvastatin-Treated Patients With Coronary Heart Disease and Diabetes or Impaired Fasting Glucose Levels: Subgroup Analyses in the Scandinavian Simvastatin Survival Study
Abstract
BACKGROUND: Patients with diabetes mellitus (DM) have a marked increase in coronary heart disease (CHD) events relative to those without DM. In a previous report from the Scandinavian Simvastatin Survival Study using a clinical case definition of DM (n = 202), simvastatin-treated patients had significantly fewer CHD events compared with placebo-treated control subjects. OBJECTIVE: To examine the effect of simvastatin therapy on CHD in patients with DM and impaired fasting glucose levels. METHODS: Using the 1997 American Diabetes Association diagnostic criteria, we assessed the effect of simvastatin therapy post hoc for an average of 5.4 years in Scandinavian Simvastatin Survival Study patients with normal fasting glucose (n = 3237), impaired fasting glucose (n = 678), and DM (n = 483). RESULTS: Simvastatin-treated patients with DM had significantly reduced numbers of major coronary events (relative risk [RR] = 0.58; P = .001) and revascularizations (RR = 0.52; P = .005). Total (RR = 0.79; P = .34) and coronary (RR = 0.72; P = .26) mortality were also reduced in DM, but not significantly, due to small sample size. In impaired fasting glucose (IFG) subjects, simvastatin use significantly reduced the number of major coronary events (RR = 0.62; P = .003), revascularizations (RR = 0.57; P = .009), and total (RR = 0.57; P = .02) and coronary (RR = 0.45; P = .007) mortality. CONCLUSION: Our results extend previous findings in patients with DM to a larger cohort, confirming the benefit of cholesterol lowering with simvastatin treatment on CHD events. In addition, significant decreases in total mortality, major coronary events, and revascularizations were observed in simvastatin-treated patients with impaired fasting glucose levels. These results strongly support the concept that cholesterol lowering with simvastatin therapy improves the prognosis of patients with elevated fasting glucose levels (> or =6.0 mmol/L [> or =110 mg/ dL]) or DM and known CHD.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
