Background:There has been debate regarding the added benefit of high-intensity statins compared with low-moderate-intensity statins, especially in patients with acute myocardial infarction (AMI).Methods and Results:The Korea Acute Myocardial Infarction Registry-National Institutes of Health consecutively enrolled 13,104 AMI patients. Of these, a total of 12,182 patients, who completed 1-year follow-up, were included in this study, and all patients were classified into 3 groups (no statin; low-moderate-intensity statin; and high-intensity statin). The primary outcome was major adverse cardiac event (MACE) including cardiac death, non-fatal MI, and repeat revascularization at 1 year. Both low-moderate-intensity and high-intensity statin significantly reduced low-density lipoprotein cholesterol (LDL-C; all P<0.001). Compared with the no statin group, both statin groups had significantly lower risk of MACE (low-moderate intensity: HR, 0.506; 95% CI: 0.413–0.619, P<0.001; high intensity: HR, 0.464; 95% CI: 0.352–0.611, P<0.001). The risk of MACE, however, was similar between the low-moderate- and high-intensity statin groups (HR, 0.917; 95% CI: 0.760–1.107, P=0.368). Multivariable adjustment, propensity score matching, and inverse probability weighted analysis also produced the same results.Conclusions:When adequate LDL-C level is achieved, patients on a low-moderate-intensity statin dose have similar cardiovascular outcomes to those on high-intensity statins.

Background: Differences in the impact of the 1- or 2-stent strategy in similar coronary bifurcation lesion conditions are not well understood. This study investigated the clinical outcomes and its predictors between 1 or 2 stents in propensity score-matched (PSM) complex bifurcation lesions.Methods and Results: We analyzed the data of patients with bifurcation lesions, obtained from a multicenter registry of 2,648 patients (median follow up, 53 months). The patients were treated by second generation drug-eluting stents (DESs). The primary outcome was target lesion failure (TLF), composite of cardiac death, target vessel myocardial infarction (TVMI), and ischemia-driven target lesion revascularization (TLR). PSM was performed to balance baseline clinical and angiographic discrepancies between 1 and 2 stents. After PSM (N=333 from each group), the 2-stent group had more TLRs (hazard ratio [HR] 3.14, 95% confidence interval [CI] 1.42–6.97, P=0.005) and fewer hard endpoints (composite of cardiac death and TVMI; HR 0.44, 95% CI 0.19–1.01, P=0.054), which resulted in a similar TLF rate (HR 1.40, 95% CI 0.83–2.37, P=0.209) compared to the 1-stent group. Compared with 1-stent, the 2-stent technique was more frequently associated with less TLF in the presence of main vessel (pinteraction=0.008) and side branch calcification (pinteraction=0.010).Conclusions: The 2-stent strategy should be considered to reduce hard clinical endpoints in complex bifurcation lesions, particularly those with calcifications.

Coronary artery disease (CAD) is the most common cause of death and physical disabilities in developed countries, even though efforts to identify and target causal factors such as hypertension and dyslipidemia have brought tremendous improvements in prevention and treatment. A rapid advance in technology has unraveled new genetic variants associated with CAD and also provided great opportunities to identify novel pathogenic mechanisms and to develop new drugs with higher specificity. Whole-genome sequencing and whole-exome sequencing has made it possible to find rare alleles that are responsible for CAD in small, affected families and case-control studies in a very efficient manner. At present, genome-wide association studies have identified more than 50 loci that explain approximately 10% of the heritability of CAD, most of which is unrelated to traditional risk factors. Mendelian randomization studies enable identification of causal factors among numerous biomarkers and to narrow down promising therapeutic targets. This review highlights new genetic approaches and demonstrates the extent to which the outcome contributes to the finding of new therapeutic targets. (Circ J 2015; 79: 8–14)

Advances in nuclear reprogramming technology have enabled the dedifferentiation and transdifferentiation of mammalian cells. Forced induction of the key transcription factors constituting a transcriptional network can convert cells back to their pluripotent status or directly to another cell fate without inducing pluripotency. To date, direct conversion to several cell types, including cardiomyocytes, various types of neurons, and pancreatic β-cells, has been reported. We previously demonstrated direct lineage reprogramming of adult fibroblasts into induced endothelial cells (iECs) in mice and humans. In contrast to induced pluripotent stem cells, for which there is consensus on the criteria defining pluripotency, such criteria have not yet been established in the field of direct conversion. We thus suggest that careful assessment of the status of converted cells using genetic and epigenetic profiling, various functional assays, and the use of multiple readouts is essential to determine successful conversion. As direct conversion does not go through pluripotent status, this technique can be utilized for therapeutic purposes without the risk of tumorigenesis. Further, direct conversion can be induced in vivo by gene delivery to the target tissue or organ in situ. Thus, direct conversion technology can be developed into cell therapy or gene therapy for regenerative purposes. Here, we review the potential and future directions of direct cell fate conversion and iECs.

Background: The clinical effect of, and additive measures to overcome the possible inhibitory calcium channel blocker (CCB)-clopidogrel interaction in Asian patients undergoing percutaneous coronary intervention is unknown. Methods and Results: A total of 900 Korean patients enrolled for the multicenter, prospective, randomized Influence of CILostazol-based triple antiplatelet therapy ON ischemic complication after drug-eluting stenT implantation (CILON-T) trial were divided into 4 groups depending on CCB prescription and type of anti-platelet therapy (dual [DAT] vs. triple [TAT; addition of cilostazol to DAT]) in a 2×2 factorial manner. The primary endpoint was a composite of cardiac death, non-fatal myocardial infarction and ischemic stroke at 6 months after PCI. On-treatment platelet reactivity (OPR) was assessed on VerifyNow P2Y12 assay. Concomitant CCB use increased OPR in the DAT group (mean±SEM: 251.2±7.6 vs. 225.6±5.1; P=0.008), but not in the TAT group (214.5±9.1 vs. 203.4±5.6; P=0.294). Primary endpoint increased by use of CCB in patients with DAT (4.9% vs. 0.9%, P=0.016), but not in those with TAT (0% vs. 1.8%, P=0.346). Addition of cilostazol to DAT reduced OPR and clinical events in patients taking CCB (P=0.007 for P2Y12 reaction units; P=0.027 for thrombotic events). CCB without concomitant cilostazol use was a significant predictor of total thrombotic events. Conclusions: Concomitant use of CCB may weaken the anti-platelet effect of clopidogrel and increase subsequent thrombotic events in Asian subjects. This hazardous CCB-clopidogrel interaction may be overcome by addition of cilostazol.
