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.展开更多

Arterial stiffness is also a good predictor of cardiovascular morbidity and mortality. The effects of benidipine, a unique dual L-IT-type calcium channel blocker, on central BP have not been reported. This study aimed to compare the effect of benidipine and Iosartan on the central BP and arterial stiffness in mild to moderate essential hypertensives. Methods This 24 weeks, multi-center, open label, randomized, active drug comparative, parallel group study was designed as a non-inferiority study. The eligible patients （n=200） were randomly assigned to receive benidipine （n=101） or Iosartan （n=99）. Radial artery applanation tonometry and pulse wave analysis were used to measure the central BP, pulse wave velocity （PWV） and augmentation index （AIx）. We also measured the metabolic and inflammatory markers. Results After 24 weeks, the central BP decreased significantly from baseline by （16.8±14.0/10.5±9.2） mmHg （1 mmHg =0.133 kPa） （systolic/diastolic BP; P 〈0.001） in benidipine group and （18.9±14.7/12.1±10.2） mmHg （P 〈0.001） in Iosartan group respectively. Both benidipine and Iosartan groups significantly lowered peripheral BP （P 〈0.001） and AIx （P 〈0.05）, but there were no significant differences between the two groups. The mean aortic, brachial and femoral PWV did not change in both groups after 24-week treatment. There were no significant changes of the blood metabolic and inflammatory biomarkers in each group. Conclusion Benidipine is as effective as Iosartan in lowering the central and peripheral BP, and improving arterial stiffness.展开更多
