The transulnar approach (TUA) has been considered both as primary access and as a secondary access site after transradial access (TRA) failure for coronary invasive procedures. However, there is little evidence supporting the use of the TUA as the first approach to diagnostic coronary angiography (CAG) or interventions. Patients (n = 587) who underwent CAG and/or angioplasty (292 patients via TRA, 295 patients via TUA) were included. The primary end points of the study were major adverse cardiac events and major vascular events (hematoma, vascular occlusion, vasospasm), and secondary end points included angiographic success, crossover rate, and angiographic procedural times. The mean age was 60 ± 21 years. The composite primary end points occurred in 34 (11.6%) patients in the TRA and 22 (7.4%) patients in the TUA arm ( P < .001). More arterial occlusion and more arterial spasm than in the TUA and similar urgent target vessel revascularization were observed in the TRA group in 48 hours. Based on previous studies and our clinical experience, we speculated that the TUA performed by an experienced operator has equal status with the TRA for coronary catheterization, especially in patients with a palpable ulnar pulse.

Purpose: to compare rates of access site complications at early (after 4 hours) and traditional (after 24 hours) removal of a compression bandage after diagnostic transradial (TR) coronary angiography (CA) in patients not receiving anticoagulants.Materials and methods. We included into this study 392 patients (mean age 63±8.7 years, 62.8% men) who underwent transradial coronary angiography. Patients were divided into 2 groups. In group 1 patients (n=221) compression bandage was removed from puncture site in 4 hours after procedure with subsequent control of radial artery patency using presence of pulse metric curve during ulnar artery compression (the reverse Barbeau test with pulse oximeter). In patients of group 2 (n=171) compression band was removed after 24 hours. In both groups control of radial artery patency was carried out after 24 hours using the reverse Barbeau test. Upon detection of radial artery occlusion (RAO) ultrasound imaging of the forearm arteries was performed.Results. No RAO was detected in group 1 while in group 2 number of detected RAO was 15 (8.8%) (р<0.05). Rates of hematomas at puncture site were not significantly different. Puncture site bleeding after band removal requiring repeated banding occurred in 1 patient of group one (0.6%); no such cases were registered in group 2 (p>0.05).Conclusion. Compared with traditional method early removal of compression bandage after TR CA was associated with lower rate of RAO.

BACKGROUND: The increased utility of CT coronary angiography (CTCA) in cardiovascular screenings of aircrew has led to the increased detection of asymptomatic coronary artery disease (CAD). A systematic review of studies relevant to the interpretation of CTCA for the occupational fitness assessment of high-risk vocations was performed, with findings used to describe the development of a pathway for the aeromedical disposition of military aviators with asymptomatic CAD.METHODS: Medline was searched using the terms CT coronary angiogram and screening and prognosis. The inclusion criteria were restricted to study populations ages > 18 yr, were asymptomatic, were not known to have CAD, had undergone CTCA, and with their associations with major adverse cardiovascular events (MACE) and other relevant cardiac outcomes reported.RESULTS: Included in this systematic review were 10 studies. When compared to subjects with no or nonobstructive CAD, those with obstructive CAD on CTCA had hazard ratios (HR) for cardiac events ranging from 1.42 to 105.48. Comparing subjects with nonobstructive CAD and those without CAD on CTCA, a lower HR of 1.19 for cardiac events was found. The annual event rates of subjects with no CAD on CTCA were extremely low, ranging from 0 to 0.5%.CONCLUSIONS: Based on the findings, we suggest that CTCA should only be performed in aircrew with higher cardiac risk profiles. Those found to have no CAD or minimal CAD (i.e., 25% stenosis) in a non-left main coronary artery on CTCA can be returned to flying duties. All other results should be further evaluated with an invasive angiogram.Cheong RWL, See B, Tan BBC, Koh CH. Coronary artery disease screening using CT coronary angiography.

Background:Since the first reported use of percutaneous transluminal coronary angioplasty, advances in the interventional cardiology arena have been fast paced. Developers and clinicians are adapting from the learning curve awarded by the time-course of drug-eluting stent (DES) evolution. BioMime™ sirolimus-eluting stent (SES) is a step towards biomimicry. The stent is built on a strut of ultra-low thickness (65μm), a cobalt–chromium platform using an intelligent hybrid of closed and open cells allowing for morphology-mediated expansion. It employs a well-known antiproliferative – sirolimus – that elutes from a known biodegradable copolymer formulation within 30 days. The resultant stent demonstrates almost 100% endothelialisation at 30 days in preclinical models.Methods:The meriT-1 was a prospective, single-arm, single-centre trial to evaluate the safety and efficacy of BioMime SES in 30 patients with a single de novo lesion in native coronary arteries. The primary safety and efficacy end-points were major adverse cardiac events (MACE) at 30 days and in-stent late lumen loss at eight months, as measured using quantitative coronary angiographic (QCA) method. Secondary safety and efficacy end-points included MACE at one and two years and angiographic binary restenosis at eight-month angiographic follow-up. Other end-points included the occurrence of stent thrombosis at acute, subacute, late and very late periods and the percentage of diameter stenosis by QCA.Results:No MACE were observed and the median in-stent late luminal loss in 20 (67%) subjects studied by QCA was 0.15mm, with 0% binary restenosis at eight-month follow-up. No stent thrombosis was observed up to one-year follow-up.Conclusions:In comparison to currently available DES, BioMime SES appears to have a considerable scientific basis for prevention of neointimal proliferation, restenosis and associated clinical events.

Introduction: Perioperative cardiovascular events are an important cause of morbidity and mortality associated with non-cardiac surgery (NCS), especially in patients with recent percutaneous coronary intervention (PCI) who require dual antiplatelet therapy. Objective: To illustrate the types and timing of different noncardiac surgeries occurring within 1 year of PCI, and to evaluate the risk of thrombotic and bleeding events according to perioperative antiplatelet management. Methods: All patients undergoing NCS within 1 year of PCI at a tertiary-care center between 2011 and 2018 were included. The primary outcome was major adverse cardiac events (MACE; composite of death, myocardial infarction, stent thrombosis or target vessel revascularization). The key secondary outcome was major bleeding, defined as ≥2 units of blood transfusion. All outcomes were evaluated at 30 days after NCS. Results: A total of 1092 NCS (corresponding to 747 patients) were included and classified by surgical risk (low: 50.9%, intermediate: 38.4%, high: 10.7%) and priority (elective: 88.5%, urgent/emergent: 11.5%). High-risk and urgent/emergent surgeries tended to occur earlier post-PCI compared to low-risk and elective ones ( Figure-A ). The incidence of MACE and bleeding was time-dependent, with an increased risk in surgeries occurring in the first 6 months post-PCI ( Figure-B ). Perioperative antiplatelet cessation occurred in 487 (44.6%) NCS and was more likely for intermediate-risk procedures and after 6 months of PCI. There was no significant association between antiplatelet cessation and cardiac events. Conclusions: Among patients undergoing NCS within 1 year of PCI, the perioperative risk of MACE is inversely related to time from PCI. Preoperative interruption of antiplatelet therapy was observed in less than half of all cases and was not associated with an increased risk of cardiac events.

Background. Despite the enormous benefits of radial access, this route is associated with a risk of radial artery occlusion (RAO). Objective. We compared the incidence of RAO in patients undergoing transradial coronary angiography and intervention after short versus prolonged hemostasis protocol. Also we assessed the efficacy of rescue 1-hour ipsilateral ulnar artery compression if RAO was observed after hemostasis. Material and Methods. Patients referred for elective transradial coronary procedures were eligible. After 6 F radial sheath removal, patients were randomized to short (3 hours) (n = 495) or prolonged (8 hours) (n = 503) hemostasis and a simple bandage was placed over the puncture site. After hemostasis was completed, oximetry plethysmography was used to assess the patency of the radial artery. Results. One thousand patients were randomized. Baseline characteristics were similar between both groups with average age 61.4 ± 9.4 years (71% male) and PCI performed on half of the patients. The RAO rate immediately after hemostasis was 3.2% in the short hemostasis group and 10.1% in the prolonged group ( p < 0.001 ). Rescue recanalization was successful only in the short group in 56.2% (11/19); at hospital discharge, RAO rates were 1.4% in the short group and 10.1% in the prolonged group ( p < 0.001 ). Conclusion. Shorter hemostasis was associated with significantly less RAO compared to prolonged hemostasis. Rescue radial artery recanalization was effective in > 50%, but only in the short hemostasis group.

Abstract Radial access has great advantages in terms of the frequency of complications, but it has one specific complication - radial artery occlusion (RAO). This complication often does not manifest itself in any way; however, it limits the use of access for the future interventions. Aim To compare methods of short and traditional hemostasis and to identify the main predictors of RAO after radial access. Materials and methods During the period from 2012 to 2018, 2000 patients were included in the study, which consisted of two parts: prospective - 1000 patients who underwent coronary angiography and percutaneous coronary intervention (PCI) with stable coronary artery disease, and retrospective part of the study, which included 1000 patients admitted for PCI from other clinics. In a prospective study, patients were divided into two groups: after coronary angiography and PCI, respectively (n=500 in the coronary angiography group and n=500 in the PCI group), and then randomized. Hemostatic bandages in the first group of patients (n=250) were removed after 12–24 hours, in the second group (n=250) - after 4±1 hours. When the occlusion of the radial artery was detected, all patients underwent an hour-long compression of the ipsilateral ulnar artery to recanalize acute RAO. Results The frequency of RAO in the retrospective part of the study was 21.8%. The frequency of RAO in the prospective part of the study was 10.2% with a traditional time hemostasis and 1.4% with a short-time compression (P<0.001). Predictors of the RAO are illustrated in table 1. Predictors of bleeding were PCI (OR 0.12, 95% CI 0.01–0.67, P=0.05) and weight (OR 1.09, 95% CI 1.02–1.18, P=0.01). Table 1. Predictors of RAO Variables Odds ratio 95% Confidential interval Significance, P Traditional-time hemostasis 8.78 4.2–21.5 <0.001 Diabetes mellitus+smoking 18.1 12.7–26.7 <0.001 Diabetes mellitus 0.45 0.25–0.83 0.009 Body mass index 0.95 0.91–0.99 0.02 Male 1.75 1.01–3.18 0.05 Protein C 0,86 0,75–0,96 0,01 Conclusion Careful examination of the patient for detecting RAO before and after interventions is essential. Short hemostasis with compression of the ipsilateral ulnar artery reduce the frequency of RAO. For short-time hemostasis, special attention should be paid to patients after PCI and with low BMI, as far as these factors are associated with a greater risk of bleeding after removal of the compression bandage.

SummaryNo prospective data demonstrating an association between the –11377 C>G adiponectin gene promoter variant and cardiovascular risk are available. We therefore prospectively evaluated the cardiovascular risk associated with adiponectin gene single nucleotide polmorphisms (SNPs) including SNP –11377 in a consecutive series of men undergoing coronary angiography. We recorded vascular events over four years in 402 men undergoing coronary angiography for the evaluation of coronary artery disease. No significant associations of SNPs +276 G>T and +45 T>G with serum adiponectin, with significant coronary stenoses >50%, or with vascular events were observed. However, for SNP –11377 C>G, serum adiponectin levels significantly decreased (Ptrend = 0.003), and the prevalence of significant coronary stenoses significantly increased from the CC over the GC to the GG genotype (ptrend = 0.004). Prospectively, the risk of vascular events significantly increased from the CC over the CG to the GG genotype of this SNP (adjusted hazard ratios 1.555 [0.957-2.525] and 2.309 [1.067–4.998], respectively; ptrend = 0.014). The –11377 C>G adiponectin gene promoter variant is i) associated with decreased serum adiponectin levels, ii) correlated with the presence of coronary atherosclerosis and iii) significantly predictive of vascular events among men undergoing coronary angiography.
