CardioExchange welcomes this guest post reprinted with permission from Dr. John M, a blog by private-practice electrophysiologist and CardioExchange member, Dr. John Mandrola. It was a brightly lit wide open room with many cubicles arranged on the periphery.  The test takers were grown-ups, but all carried that worried student look.  The secretary at the desk who checked you in made TSA people seem jovial.  No personal effects were allowed, including a full-fledged divorce of the cell phone. Mysteriously, the test was devoid of ovals or pencils. A former senior partner… Continue Reading

Although I’ve been in practice for only 1 year, I have on many occasions found myself defending against statements such as “Every cardiologist practices prevention” and “We all do a lipid panel on our patients.” Some even say, “I order a CRP… Continue Reading

My colleagues and I reached this conclusion in an investigation of the relationship between pre-procedural glucose levels and CI-AKI in 6,358 patients who underwent coronary angiography during hospitalization for MI. We found found a high risk for CI-AKI among those patients who had pre-procedural hyperglycemia but no known diabetes, even when the baseline renal function was normal. While diabetes is a known risk factor for CI-AKI, it has not been clear until now that the risk extends to hyperglycemic patients without… Continue Reading
