Additional reductions in low-density lipoprotein-cholesterol (LDL-C) via antidiabetic therapies should be considered in statin-using patients with sub-optimal LDL-C levels. We compared the efficacy of anagliptin and sitagliptin, two antidiabetic therapies, in reducing LDL-C in type 2 diabetic patients. A randomized, open-label, parallel-group trial was conducted at 17 centres in Japan between April 2015 and January 2018. Adults (age ≥20 years) with type 2 diabetes, any atherosclerotic vascular lesions, and statin prescriptions were included. Anagliptin or sitagliptin were administered for 52 weeks. Primary and secondary endpoints were changes in LDL-C and haemoglobin A1C (HbA1c) levels, respectively. We assessed the superiority (primary endpoint) and non-inferiority (secondary endpoint) of anagliptin over sitagliptin. This study was registered at Clinicaltrials.gov (NCT02330406). Of 380 participants, 353 were eligible and randomized. Mean participant age was 68 years, and 61% were males. Baseline median LDL-C and HbA1c were 108 mg/dL and 6.9%, respectively. Changes in LDL-C were −3.7 mg/dL with anagliptin and +2.1 mg/dL with sitagliptin at 52 weeks, and the estimated treatment difference was a significant −4.5 mg/dL (P = 0.01 for superiority). Changes in HbA1c were +0.02% with anagliptin and +0.12% with sitagliptin (P < 0.0001 for non-inferiority). Overall, anagliptin was superior to sitagliptin in lowering LDL-C without deteriorating HbA1c.
on behalf of the CREDO-Kyoto PCI/CABG registry cohort-2 investigators Background-There still remain safety concerns on surgical procedures after coronary drug-eluting stents (DES) implantation, and optimal management of perioperative antiplatelet therapy (APT) has not been yet established. Methods and Results-During 3-year follow-up of 12 207 patients (DESϭ6802 patients and bare-metal stent [BMS] onlyϭ5405 patients) who underwent coronary stent implantation in the CREDO-Kyoto registry cohort-2, surgical procedures were performed in 2398 patients (DESϭ1295 patients and BMSϭ1103 patients). Surgical procedures (early surgery in particular) were more frequently performed in the BMS group than in the DES group (4.4% versus 1.9% at 42-day and 23% versus 21% at 3-year, log-rank Pϭ0.0007). Cumulative incidences of death/myocardial infarction (MI)/stent thrombosis (ST) and bleeding at 30 days after surgery were low, without differences between BMS and DES (3.5% versus 2.9%, Pϭ0.4 and 3.2% versus 2.1%, Pϭ0.2, respectively). The adjusted risks of DES use relative to BMS use for death/MI/ST and bleeding were not significant (hazard ratio: 1.63, 95% confidence interval: 0.93 to 2.87, Pϭ0.09 and hazard ratio: 0.6, 95% confidence interval: 0.34 to 1.06, Pϭ0.08, respectively). The risks of perioperative single-and no-APT relative to dual-APT for both death/MI/ST and bleeding were not significant; single-APT as compared with dual-APT tended to be associated with lower risk for death/MI/ST (hazard ratio: 0.4, 95% confidence interval: 0.13 to 1.01, Pϭ0.053). Conclusions-Surgical procedures were commonly performed after coronary stent implantation, and the risk of ischemic and bleeding complications in surgical procedures was low. In patients selected to receive DES or BMS, there were no differences in outcomes. Perioperative administration of dual-APT was not associated with lower risk for ischemic events.

Aims White blood cell (WBC) count in healthy people is associated with the risk of coronary artery disease (CAD) and mortality. This study aimed to determine whether WBC count predicts heart failure (HF) requiring hospitalization as well as all-cause death, acute myocardial infarction (AMI) and stroke in patients with Type 2 diabetes mellitus and established CAD. Methods We conducted this retrospective registry study that enrolled consecutive patients with Type 2 diabetes mellitus and CAD based on coronary arteriography records and medical charts at 70 teaching hospitals in Japan from 2005 to 2015. A total of 7608 participants (28.2% women, mean age 68 ± 10 years) were eligible. In the cohort, the median (interquartile range) and mean follow-up durations were 39 (16.5-66.1 months) and 44.3 ± 32.7 months, respectively. The primary outcome was HF requiring hospitalization. The secondary outcomes were AMI, stroke, all-cause death, 3-point major adverse cardiovascular events (MACE) (AMI/stroke/death) and 4-point MACE (AMI/stroke/death/HF requiring hospitalization). Outcomes were reported as cumulative incidences (proportion of patients experiencing an event) and incidence rates (events/100 personyears). The primary and secondary outcomes were assessed using the Kaplan-Meier method and were compared using the log-rank test stratified by the baseline WBC count. The association between the WBC count at baseline and each MACE was assessed using the Cox proportional hazard model and expressed as the hazard ratio (HR) and 95% confidence interval (CI) after adjusting for other well-known risk factors for MACE. Results During the follow-up, 880 patients were hospitalized owing to HF. The WBC Quartile 4 (≥7700 cells/μL) had significantly lower HF event-free survival rate (log-rank test, P < 0.001). The HRs for HF events requiring hospitalization with each WBC quartile compared with the lowest in the first WBC quartile were 1 for Quartile 1 (WBC < 5300 cells/μL), 1.20 (95% CI, 0.96-1.5; P = 0.1) for Quartile 2 (5300 ≤ WBC < 6400), 1.34 (95% CI, 1.08-1.67; P = 0.009) for Quartile 3 (6400 ≤ WBC < 7700) and 1.62 (95% CI, 1.31-2.00; P < 0.001) for Quartile 4 after adjusting for covariates. Similar findings were observed for the risk of AMI and death; however, no significant difference was found for stroke. WBC Quartile 4 patients had a significantly lower 3-or 4-point MACE-free survival rate (log-rank test, P < 0.0001). Conclusions A higher WBC count is a predictor of hospitalization for HF, all-cause death and AMI but not for stroke in patients with concurrent Type 2 diabetes mellitus and established CAD.
Although the guidewire crossing into the side branch was impossible by conventional antegrade methods when the bifurcation angle became 150° or more, the guidewire crossing into such a highly angulated side branch was easily possible using the reverse wire technique. The optimal guidewire selection for the reverse wire technique is the polymer-jacket hydrophilic guidewire with a round shape 3 cm from the guidewire tip.
