Nissen did a meta-analysis looking at the increased risk of myocardial infarction and death from cardiovascular causes from Avandia and found a 41 percent greater risk and his analysis excluded anyone with a high risk of or a prior MI. The RECORD team released interim results showing that there was little difference in the risk of MI or death of all people on the drug with or without a history of MI... "As compared with the control group, the rosiglitazone group had no evidence of an increased risk of death, either from any cause (hazard ratio, 0.93; 95% CI, 0.67 to 1.27) or from cardiovascular causes (hazard ratio, 0.80, 95% CI, 0.52 to 1.24). The primary end point included all first hospitalizations or deaths from cardiovascular causes and as such included myocardial infarction and congestive heart failure. "
NEJM changes the goal post and definition of safety by demanding that Avandia show that it is cardioprotective...to wit; David Nathan's unctuous editorial comment: "Considering the low power of the study and the trend for more adverse cardiovascular outcomes in the rosiglitazone-treated group, it is highly unlikely that the study will ever establish a cardiovascular benefit for rosiglitazone." Thanks David and maybe it will be a source of renewable energy too.
Nathan goes on to write: "It is reasonable to ask whether physicians should feel comfortable using a drug that might have an 8% excess risk of severe cardiovascular disease or death from cardiovascular causes. " And as we all know, there are subpopulations that will carry about 80 percent of that risk.
In patients that have a 50 percent greater chance of having a stroke, heart attack or heart failure if they stop taking the medcine? No one is doubting that there are other tools out there for controlling diabetes but the last time I checked the incidence of the disease was increasing as was the prevalence. More people are dying from the disease and if a PPAR can reduce that a 50 percent increase in absolute risk of stroke with a drug that carries a 2 percent or less risk of MI and other treatments are not working....
