Abstract

The marked sentences are the ones the graph read a number from.

backgroundPatients 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.

objectiveTo examine the effect of simvastatin therapy on CHD in patients with DM and impaired fasting glucose levels.

methodsUsing 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).

resultsSimvastatin-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.

conclusionOur 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.
