OBJECTIVES: The goal of this study was to investigate the nature of the association between silent ischemia and postoperative myocardial infarction (PMI). BACKGROUND: Silent ischemia predicts cardiac morbidity and mortality in both ambulatory and postoperative patients. Whether silent stress-induced ischemia is merely a marker of extensive coronary artery disease or has a closer association with infarction has not been determined. METHODS: In 185 consecutive patients undergoing vascular surgery, we correlated ischemia duration, as detected on a continuous 12-lead ST-trend monitoring during the period 48 h to 72 h after surgery, with cardiac troponin-I (cTn-I) measured in the first three postoperative days and with postoperative cardiac outcome...

Patients with coronary artery disease are particularly at risk perioperatively, as myocardial infarction, unstable angina, severe arrhythmia and cardiac death may occur. These events are often preceded by prolonged silent myocardial ischaemia (MI). Moreover, perioperative MI predicts long-term adverse cardiac outcome. Therefore, it is logical to prevent and treat MI. However, the detection of perioperative MI is difficult because of low sensitivity of ST-segment monitoring, low specificity of echocardiography and insufficient availability of equipment for its monitoring...

This study attempted to determine the possibility for steal phenomenon after coronary surgery using internal mammary artery (IMA) as graft with unligated big side branches. The internal mammary artery (IMA) is considered to be the conduct of choice in coronary artery bypass grafting (CABH). The more IMA grafts are used, the more increases the significance of IMA anomalies and notably the large side branches for the surgical results. The importance of coronary subclavian steal syndrome is well known. We represent two clinical cases with big intercostal branches visualised at the postoperative coronary angiography, performed to evaluate the coronary and graft status cause of recurrent postoperative anginal pain...
