Whether this advantage of CABG over PCI is confined to diabetics who require insulin is unknown. We review the published literature comparing CABG with PCI in diabetics including 8 cohorts and 4,786 patients. There was a lower rate for all-cause mortality （Relative risk （RR）： 0.78, 95% confidence interval （CI）： 0.62-0.99）, and for major adverse cardiac and cerebrovascular events （MACCE, RR： 0.59, 95% CI： 0.47-0.75） for CABG compared to PCI. Composite outcome of mortality, myocardial infarction and stoke was similar between CABG and PCI （RR： 0.87, 95% CI： 0.54-1.42）. Visual inspection of the forest plots showed that in most analyses, the point estimates of the RR are similar between the insulin requiring group and non-insulin requiring group. On meta-regression, there was no interaction between status of insulin requirement and revascularization strategies （P 〉 0.05 for all）. The pre- sented data on the still unpublished analysis of the FREEDOM trial showed similar results. Thus, in the current era, CABG is superior to PCI with lower mortality and MACCE rates, but the state of insulin requirement had no effect on the outcomes from the two revascularization strategies.展开更多

The lat...Anomalous left coronary artery from the pulmonary artery(ALCAPA) is most commonly diagnosed within the first year of life with congestive heart failure symptomatology reflecting left ventricle(LV) dysfunction. The late diagnosis of ALCAPA is presented in a 5-yearold without significant LV dysfunction, mild LV dilatation and only mild mitral regurgitation that did not change significantly after surgery. The timing of surgical intervention in the late diagnosis of ALCAPA remains unclear despite risks of significant ongoing myocardial injury secondary to coronary artery hypoperfusion and progressive mitral valve dysfunction. Intervention in this case allows for revascularization which may reverse ventricular and valvular dysfunction.展开更多

One hundred and two patients were randomized to receive RIPC(3 cycles of 5 min ischemia and 5 min reperfusion in the upper arm after induction of anesthesia) or no RIPC(control). Primary outcome was POAF lasting for five minutes or longer during the first seven days after surgery. Secondary outcomes included length of hospital stay, incidence of inpatient mortality, myocardial infarction, and stroke. RESULTS POAF occurred at a rate of 54% in the RIPC group and 41.2% in the control group(P = 0.23). No statistically significant differences were noted in secondary outcomes between the two groups. CONCLUSION This is the first study in the United States to suggest that RIPC does not reduce POAF in patients with elective or urgent cardiac surgery. There were no differences in adverse effects in either group. Further studies are required to assess the relationship between RIPC and POAF.展开更多

The aim of this study was to assess the current occurrence of LMCS as a delayed complication of percutaneous angioplasty (PTCA) of the left coronary branches in our institution. Methods The medical records of patients referred for coronary artery by-pass surgery from the same Cardiology Unit in the January 2003 to December 2006 period and presenting a significant (> 50%) LMCS as a new finding following a PTCA of the left coronary artery branches, were reviewed. Patients with retrospective evidence of any LMCS at previous coronary angiographies preceding the percutaneous procedure were excluded. Results Thirty-seven patients (5 females, mean age 71.1±8.6 years) out of 944 (4%) having undergone a PTCA, fulfilled the inclusion criteria, 19 (51%) after a procedure also involving the LAD coronary artery. Extraback-up guiding catheters were used in most cases. Use of multiple wires or balloons was observed in 3 cases (8%). Rotablator and proximal occlusion device were used in one case respectively (3%). Twenty patients (54%) have had more than one percutaneous coronary intervention on the left coronary branches. The mean time elapsed from the first angioplasty and surgical intervention was 18.1±7.8 months. Conclusions The potential occurrence of LMCS following a percutaneous intervention procedure, especially when complicated and repeated, should not be underestimated in the current era. This evidence may offer the rationale to schedule non-invasive imaging tests to monitor left main coronary patency after the procedure as well as to fuel further research to develop less traumatic materials.展开更多

PAF is also associated with increased morbidity and mortality including complications resulting from long-term anticoagulation therapy. Currently, the most effective therapy to prevent PAF after cardiac surgery remains undetermined. Inflammatory mechanisms may be partly responsible for PAF. Minocycline, a tetracycline antibiotic, has specifically an atrial myocytes anti-apoptotic effect, decreases right atrial tissue inflammation and oxidative stress activity. These observations led to this trial’s hypothesis that the addition of minocycline to amiodarone may favorably affect suppression of PAF. Methods: This trial compares the efficacy and safety of minocycline plus amiodarone versus amiodarone alone, in the prevention of PAF among adult patients undergoing cardiac procedures. All patients receive Beta-blocker agent. The primary outcome is PAF occurrence. Secondary outcomes include thromboembolic stroke, need for pharmacologic or electric cardioversion, mediastinal exploration for sepsis or for anticoagulation-related bleeding, serious drug side effects, length of hospital stay and 30-day mortality from cardiovascular causes. Results: This is an ongoing prospective single center randomized controlled clinical trial. Conclusion: The trial provides information on the comparative effectiveness of this low-risk prevention therapy of PAF that could be integrated in clinical practice.
