Right Heart Catheterization and Cardiac Complications in Patients Undergoing Noncardiac Surgery: An Observational Study

Article Abstract:

Right heart catheterization may not reduce the risk of heart problems in surgery patients and may even increase the risk. This procedure is done on patients at high risk of heart problems even when they are having surgery on another part of the body.

Detection and significance of intraoperative and postoperative myocardial ischemia in peripheral vascular surgery

Article Abstract:

Patients undergoing vascular surgery who develop myocardial ischemia before surgery are more likely to have a heart attack after surgery. Myocardial ischemia occurs when the blood supply to the heart is reduced. Of 115 patients undergoing surgery who were monitored before, during and after surgery, 16 had a heart attack or unstable angina within 48 hours of the operation. Fourteen had had myocardial ischemia before and after the operation. Patients who did not have myocardial ischemia before, during or after the operation were less likely to have a heart attack or angina. A heart attack or angina was more likely to happen in patients who had a history of coronary artery disease, congestive heart failure, heart attack or hypertension. Fourteen of the patients who had a heart attack or angina after surgery had a history of diabetes or coronary artery disease or were over 70 years old.

Supraventricular arrhythmia in patients having noncardiac surgery: clinical correlates and effect on length of stay

Article Abstract:

Many surgical patients may develop a heart arrhythmia during or after surgery. Researchers used electrocardiography to detect heart arrhythmias in 4.181 patients who had major non-cardiac surgery. All the patients had a normal heart rhythm before surgery. Eight percent developed an arrhythmia, either during surgery (2%) or after (6%). Older men were more likely to develop an arrhythmia as were those with pre-existing heart disease. Surgery on the abdomen and chest were most likely to lead to arrhythmia. Arrhythmia during or after surgery increased hospital stays an average of 33%.
