Objectives To evaluate the age-related one-year major adverse cardiocerebrovascular events （MACCE） after percutaneous coronary intervention （PCI） in acute myocardial infarction （AMI）. We analyzed the association between age and one-year MACCE after AMI. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institue of Health （KAMIR-NIH） between November 2011 and December 2015 were classified into four groups according to age （Group I, 〈 60 years, n = 4199; Group II, 60-70 years, n = 2577; Group III; 70-80 years, n = 2774; Group IV, ≥ 80 years, n = 1018）. Patients were analyzed for one-year composite of MACCE （cardiac death, myocardial infarction, target vessel revascularization, cerebrovascular events） after AMI. Results The one-year MACCE in AMI were 3.5% （Group I）, 6.3% （Group II）, 9.6% （Group III） and 17.6% （Group IV）. After adjustment for confounding para- meters, the analysis results showed that patients with AMI had incremental risk of one-year MACCE [Group II, adjusted hazard ratios （aHR） = 1.224, 95% CI： 0.965-1.525, P = 0.096; Group III, aHR = 1.316, 95% CI： 1.037-1.671, P= 0.024; Group IV, aHR = 1.975, 95% CI： 1.500-62.601, P〈 0.001） compared to Group I. Especially, cardiac death in the composite of primary end point played a major role in this effect （Group II, aHR = 1.335, 95% CI： 0.941-1.895, P= 0.106; Group III, aHR = 1.575, 95% CI： 1.122-2.210, P= 0.009; Group IV, aHR = 2.803, 95% CI： 1.937-4.054, P 〈 0.001）. Conclusions Despite advanced techniques and medications for PCI in AMI, age still exerts a powerful influence in clinical outcomes. Careful approaches, even in the modem era of developed cardiology are needed for aged-population in AMI intervention.

Background There are numerous but conflicting data regarding gender differences in outcomes following percutaneous coronary intervention(PCI). Furthermore, gender differences in clinical outcomes with acute myocardial infarction(AMI) following PCI in Asian population remain uncertain because of the under-representation of Asian in previous trials. Methods A total of 13,104 AMI patients from Korea Acute Myocardial Infarction Registry-National Institute of Health(KAMIR-NIH) between November 2011 and December 2015 were classified into male(n = 8021, 75.9%) and female(n = 2547, 24.1%). We compared the demographic, clinical and angiographic characteristics, 30-days and 1-year major adverse cardiac and cerebrovascular events(MACCE) in women with those in men after AMI by using propensity score(PS) matching. Results Compared with men, women were older, had more comorbidities and more often presented with non-ST segment elevation myocardial infarction(NSTEMI) and reduced left ventricular systolic function. Over the median follow-up of 363 days, gender differences in both 30-days and 1-year MACCE as well as thrombolysis in myocardial infarction minor bleeding risk were not observed in the PS matched population(30-days MACCE: 5.3% vs. 4.7%, log-rank P = 0.494, HR = 1.126, 95% CI: 0.800-1.585;1-year MACCE: 9.3% vs. 9.0%, log-rank P = 0.803, HR = 1.032, 95% CI: 0.802-1.328;TIMI minor bleeding: 4.9% vs. 3.9%, log-rank P = 0.215, HR = 1.255, 95% CI: 0.869-1.814). Conclusions Among Korean AMI population undergoing contemporary PCI, women, as compared with men, had different clinical and angiographic characteristics but showed similar 30-days and 1-year clinical outcomes. The risk of bleeding after PCI was comparable between men and women during one-year follow up.

Controlling the properties of piezoelectric thin films is a key aspect for designing highly efficient flexible electromechanical devices. In this stud）~ the crystallographic phenomena of PbZr1-xTixO3 （PZT） thin films caused by distinguished interfacial effects are deeply investigated by overlooking views, including not only an experimental demonstration but also ab initio modeling. The polymorphic phase balance and crystallinity, as well as the crystal orientation of PZT thin films at the morphotropic phase boundary （MPB）, can be stably modulated using interfacial crystal structures. Here, interactions with MgO stabilize the PZT crystallographic system well and induce the texturing influences, while the PZT film remains quasi-stable on a conventional A1203 wafer. On the basis of this fundamental understanding, a high-output flexible energy harvester is developed using the controlled-PZT system, which shows significantly higher performance than the unmodified PZT generator. The voltage, current, and power densities are improved by 556%, 503%, and 822%, respectively, in comparison with the previous flexional single-crystalline piezoelectric device. Finally, the improved flexible generator is applied to harvest tiny vibrational energy from a real traffic system, and it is used to operate a commercial electronic unit. These results clearly indicate that atomic-scale designs can produce significant impacts on macroscopic applications.
