OBJECTIVE: The aim of this study was to investigate (1) whether the learning curve of new catheterization laboratory operators increases the incidence of complications of transradial access during percutaneous coronary interventions and (2) whether manual compression with a two-step approach is safe and efficient for radial access hemostasis. METHODS: We performed a prospective study with all consecutive patients who underwent a coronary diagnostic or intervention procedure with radial access. The primary end point was a composite of pulseless radial artery of the wrist and hematoma evaluated after 24 hours. The secondary end point of efficacy was defined as the presence of bleeding or hematoma after 30 seconds. RESULTS: From March 2016 to June 2016, 150 consecutive patients, of whom 147 underwent coronary angiography and/or percutaneous coronary intervention through radial access, were included in the present study. The primary end point was present in 33%, but pulseless radial artery of the wrist was present only in 5.3%. We found that the incidence of primary end point was statistically different according to the number of puncture attempts, with a cutoff of two punctures with blood. The secondary end point of safety was present only in 4.7% of the cases. CONCLUSION: Radial access is feasible and safe even if performed by training physicians. Manual compression with early evaluation after 30 seconds is a safe technique for managing the radial access after sheath removal.

BACKGROUND: Circulating endothelial progenitors cells (EPCs) play a critical role in neovascularization and endothelial repair. There is a growing evidence that hyperglycemia related to Diabetes Mellitus (DM) decreases EPC number and function so promoting vascular complications. AIM OF THE STUDY: This study investigated whether an intensive glycemic control regimen in Type 2 DM can increase the number of EPCs and restores their function. METHODS: Sixty-two patients with Type 2 DM were studied. Patients were tested at baseline and after 3 months of an intensive regimen of glycemic control. The Type 2 DM group was compared to control group of subjects without diabetes. Patients with Type 2 DM (mean age 58.2±5.4 years, 25.6% women, disease duration of 15.4±6.3 years) had a baseline HgA1c of 8.7±0.5% and lower EPC levels (CD34+/KDR+) in comparison to healthy controls (p<0.01). RESULTS: The intensive glycemic control regimen (HgA1c decreased to 6.2±0.3%) was coupled with a significant increase of EPC levels (mean of 18%, p<0.04 vs. baseline) and number of EPCs CFUs (p<0.05 vs. baseline). CONCLUSION: This study confirms that number and bioactivity of EPCs are reduced in patients with Type 2 DM and, most importantly, that the intensive glycemic control in Type 2 DM promotes EPC improvement both in their number and in bioactivity.
