Previous studies have shown that up to 50% of healthy patients may develop ST-segment changes during upper gastrointestinal endoscopy.
In this study, researchers from Denmark evaluated myocardial blood flow in 11 patients during endoscopic retrograde cholangiopancreatography (ERCP).
|20% develop ischemia during ERCP.|
The patients were monitored with a Holter tape recorder and underwent myocardial perfusion scintigraphies in order to evaluate myocardial perfusion at rest and during ERCP.
The team found that, of the 10 patients who completed the study, 8 had no sign of myocardial ischemia, while 2 patients developed signs of ischemia during ERCP.
Dr Christensen's research team, from Hvidovre University Hospital, concluded, "Patients undergoing ERCP may develop true myocardial ischemia with reduced myocardial blood flow".
"Although this is a small-scale study, these findings strongly support the use of alternative methods for diagnostic evaluation of the pancreatic duct and biliary tree".
