However, the optimal revascularization strategy for patients with LMCA disease and left ventricular dysfunction is still unclear. This study sought to examine long-term comparative outcomes after percutaneous coronary intervention (PCI) or a coronary artery bypass grafting (CABG) according to the severity of left ventricular dysfunction. The authors evaluated a total of 3,488 patients with LMCA disease who underwent CABG (n=1,355) or PCI (n=2,133) from the IRIS-MAIN (Interventional Research Incorporation Society-Left MAIN Revascularization) registry. Left ventricular function was categorized according to left ventricular ejection fraction (LVEF) as normal function (LVEF≥55%), mild dysfunction (LVEF≥45% to<55%), moderate dysfunction (LVEF≥35% to<45%), or severe dysfunction (LVEF<35%). The primary outcome was a composite of death, myocardial infarction, or strokeft Main Disease Treatment; NCT01341327). In the revascularization of LMCA disease, PCI was associated with an inferior primary composite outcome of death, MI, or stroke compared with CABG in patients with moderate or severe left ventricular dysfunction. However, the risk for the primary outcome was comparable between PCI and CABG in those with normal or mild left ventricular dysfunction. (Observational Study for Left Main Disease Treatment; NCT01341327). The purpose of this study was to determine if shear bond resistance of orthodontic brackets bonded to enamel is associated with genes implicated in the enamel mineralization process. Ninety-two permanent, caries-free premolars extracted for orthodontic purposes and their associated saliva samples were obtained. Eighteen single nucleotide polymorphisms (SNPs) were studied for association with shear bond resistance. The genes of interest in this study were those previously as
