In one state, percentage of morbidly obese presenting for percutaneous coronary intervention nearly doubled in 1998-2009

   According to an analysis of data on patients enrolled in a medical insurance registry in the American state of Michigan, the percentage of morbidly obese patients presenting for percutaneous coronary intervention (PCI) increased by 191% over the period 1998-2009.

    Michael Buschur, MD, and colleagues at the University of Michigan Medical Center in Ann Arbor, Michigan, examined the prevalence of morbid obesity (BMI >/=40) among 227,044 patients undergoing PCI. In addition to the 191% increase in overall morbidity, compared with overweight patients (BMI 25-30) they had significant increases in vascular complications (2.82% vs 2.25%, P <0.05) and contrast-induced nephropathy (4.74% vs 3.01%, P <0.05), but no significant difference in mortality (0.90% vs 1.06%, P=0.14).

   “The dramatic increase in the number of morbidly obese patients has important implications for technical considerations of cardiac catheterization, design of the catheterization lab to accommodate these patients and, more importantly, for the prevention of obesity,” Dr. Buschur and colleagues concluded.
