A Concern About Some Clinical Trials
I am concerned about clinical trials that try to show that the treatment of myocardial infarction is better using method X than when method Y is used.

I question whether all of the physicians who see patients in these clinical trials recognize that Type D personality plays a role in the poor survival rate of such patients. Such patients have very negative emotions and do not do well.

This is brought to the fore by Pedersen and colleagues, who studied Type D personality in patients with bare metal stents or sirolimus-eluting stent implantation. They discovered that Type D personality was an independent risk factor for adverse events in such patients.

Could it be that type D behavior is overlooked by some, but not by all, doctors? Could this oversight alter the results of the trials?
