Two common ways you might misinterpret medical research

Posted on by Kurt Jensen

Sophisticated statistics in medical research can be hard to translate to layman's terms, and when they are, these common misinterpretations can be downright misleading.

1. Odds ratios don't express relative risk.

In 1999, media reports resulting from a study published in the New England Journal of Medicine wrongly suggested that black patients and women were 40 percent less likely than white patients and men, respectively, to undergo cardiac catheterization.

The study's authors had used odds ratios to describe the significance of their findings—a common practice among statistically sophisticated researchers—which showed that black patients and women were definitely less likely to be referred for invasive procedures than white patients and men, but not how much less likely.

Study finds risky drug interaction between two common statins and anti-clotting drug for stroke

Posted on by Kurt Jensen

If simvastatin or lovastatin are combined with dabigatran—brand name Pradaxa, an anti-clotting drug—hemorrhage risk increases.

A study published today in the Canadian Medical Association Journal found that within a cohort of almost 46,000 patients treated with dabigatran, the use of simvastatin or lovastatin, relative to other statins, increased the risk of a major hemorrhage by approximately 42 percent.*

Administrative data supported the authors' hypothesis that these two commonly-prescribed, cholesterol-lowering statins would "increase the amount of dabigatran absorbed by the body," reads the St. Michael's Hospital press release, "something other statins would not be expected to do." A higher concentration of dabigatran, in turn, would result in higher bleeding risk.

Cardiac cath team gets a new member. Defining a new sub-specialty: interventional echocardiography

Posted on by Kurt Jensen

Structural heart procedures are growing, and so is the cath lab team.

For two straight years, Diagnostic and Interventional Cardiology (DAIC) magazine has reported from the American Society of Echocardiography (ASE) Annual Scientific Sessions on the rise of a new sub-specialty—interventional echocardiography.

Interventional echocardiography crucial to structural heart

Structural heart procedures have seen rapid growth in the cath lab—and have been a featured topic at many of our 2016 regional educational conferences—and for all but the most expert interventionalists, echocardiography plays a big role in those cases.
