Prevalence of electrocardiographic and echocardiographic abnormalities in ambulatory ischemic colitis.

The aim of this study was to evaluate the prevalence of cardiac arrhythmia and intracardiac embolic process in ambulatory ischemic colitis. From November 1994 to November 1997, 33 consecutive cases of ambulatory ischemic colitis were detected. This study included 21 women and 12 men with a mean age of 71 years. All patients underwent a cardiovascular investigation including questioning, electrocardiogram, 24-hr ambulatory electrocardiography and transthoracic echocardiography. A prior history of ischemic colitis was found in four cases (12%). Cardiac arrhythmia was detected in eight cases. Transthoracic echocardiography showed an intracardiac process, potentially responsible for a peripheral embolism, in four cases. In conclusion, the aggregate, in 33% of the patients, there was potential cardiac etiology. This suggests that when ambulatory ischemic colitis occurs, it is necessary to perform an exhaustive cardiovascular evaluation similar to those performed in other ischemic diseases.
