摘要:
The authors analyzed the early outcomes in two groups of patients undergoing coronary artery bypass grafting (CABG) with single versus bilateral internal thoracic arteries (ITA) in their institution. One thousand sixty-nine patients underwent CABG with single or bilateral ITAs from 1990 to 2000. Of these patients, 911 (85.2%) had single ITA and 158 had bilateral ITA (14.8%). The incidence of tobacco abuse was 40.3% in the single ITA group and 56.7% in the double ITA group (P= 0.0001). The incidence of perioperative myocardial infarction, renal failure, reoperation for bleeding, stroke, or operative mortality did not differ in the two groups. There was a 4.4% incidence of mediastinitis in the bilateral ITA group versus 2.2% in the single ITA group (P= 0.0602). Early outcomes after bilateral ITA grafting for CABG are similar to single ITA grafting. Careful judgment should be exercised in selecting patients for bilateral ITA grafting, particularly if the patient smokes.

摘要:
Significant progress in cardiac surgery, and specifically the surgical management of coronary artery disease, has been due in large part to enabling technology. Robotic systems have been recently developed and refined for use in cardiac surgery to facilitate, among other procedures, a totally endoscopic approach to coronary artery bypass surgery. These systems enhance precision through endoscopic approaches by specifically addressing the inherent limitations of conventional endoscopic coronary microsurgical instrumentation via computerized, digital interface, telemanipulation technology. With a combined experience of 125 patients, several groups have independently demonstrated the clinical feasibility of totally endoscopic coronary artery bypass with two commercially available robotic telemanipulation systems. Additional enabling technology is needed to overcome the challenges currently limiting development and widespread application of totally endoscopic off-pump multivessel coronary artery bypass surgery.

摘要:
In the past few years, several clinical trials with low–molecular-weight heparins in acute coronary syndromes without ST-segment elevation have been published. In the acute phase of treatment, enoxaparin obtained better results than unfractionated heparin, but dalteparin and nadroparin did not. Enoxaparin also obtained better results than tinzaparin. From these results, it can be assumed that the efficacy of enoxaparin is higher than that of dalteparin and nadroparin. However, because low–molecular-weight heparins have not been compared head to head (except in the case of enoxaparin and tinzaparin), and given the differences between studies in patient selection criteria, design, treatment strategies, and efficacy variables, it cannot be concluded that one low–molecular-weight heparin is superior to another in the acute phase of treatment. Prolonged dalteparin treatment suggests a benefit, particularly for patients at high risk (defined as those with high troponin levels), and it can also be useful in patients waiting for invasive procedures.

摘要:
Atherosclerosis and its thrombotic complications are the major cause of morbidity and mortality in the industrialized world. The progression of atherosclerotic plaques in coronary circulation is modulated by several risk factors. It is now clear that plaque composition is a major determinant of plaque disruption and superimposed thrombosis. Plaque vulnerability, defined as the propensity of plaques to disrupt, is further determined by intrinsic and extrinsic triggering factors. After disruption, the fatty core of the plaque and its high content of tissue factor provide a powerful substrate for the activation of the coagulation cascade. Plaque disruption can be clinically silent or cause symptoms of ischemia depending on thrombus burden and the degree of vessel occlusion. In addition, plaque disruption and subsequent healing are recognized to play key roles in the rapid plaque progression. This review looks at the mechanisms underlying the development and progression of atherosclerotic plaques, factors leading to plaque rupture and subsequent thrombosis, and their clinical consequences as potential targets for future research.

摘要:
A recent shift in the clinical paradigm of acute coronary syndromes led to a burst of activity in developing animal models related to plaque vulnerability. In the present review, animal models of spontaneous and induced plaque rupture, thrombosis, and hemorrhage and “vulnerability endpoints” in conventional models of atherosclerosis are discussed. These endpoints include readouts related to biomechanical properties of the plaques, collagen turnover, underlying inflammation, and lipid accumulation. Challenges in model validation are emphasized. Development of new animal models and new tools of monitoring plaque vulnerability will facilitate design of plaque-stabilizing therapies.

摘要:
Angioscopy allows direct visualization of the coronary artery lumen and provides detailed information regarding the surface characteristics of the vessel wall and specific lesions causing acute coronary syndromes. Disruption of a plaque, ulceration, tears, fissures, lipid-rich or fibrous lesions, and luminal or mural thrombus can be readily detectedin vivo.Characterization of culprit lesions in various coronary syndromes reveals the different mechanisms of ischemia. The predominant lesion in acute myocardial infarction is an ulcerated, yellow plaque with thrombus. In unstable angina, different substrates can be seen, from the lipid-rich lesion with thrombus to the fibrous smooth plaque, reflecting a varied physiopathology. Because of its ability to detect superficial lipid pools, angioscopy may be valuable for the detection of vulnerable plaques.
