RESUMO
BACKGROUND: The distal radial artery (dRA) approach at anatomical snuff box has gained attention of the interventional cardiologist in last few years. The procedural success rate by this novel approach depends on size of the radial artery and therefore the study was planned to study the size of distal radial artery. METHODS: Total of 1004 patients of >18 years of age undergoing coronary catheterization were included in the study. The vessel diameter was measured from media to media in the anatomical snuff box a day prior to coronary catheterization. RESULTS: The mean diameter of right radial artery at conventional access site was 2.56 ± 0.35 mm and at distal access site 2.23 ± 0.39 mm (p < 0.001). Females had significantly smaller radial artery diameter as compared to males at right conventional access site (2.42 ± 0.36 mm vs 2.60 ± 0.34 mm; p < 0.001) and distal access site (2.09 ± 0.38 mm vs 2.27 ± 0.39 mm; p < 0.001). The diameter of the right dRA was not significantly correlated with age (r2 linear = 0.002, p = 0.0475) but was positively correlated with height and weight (r2 linear = 0.076, p = <0.001 and r2 linear = 0.005, p = <0.001) and negatively correlated with BMI (r2 linear = 0.076, p = 0.519). CONCLUSIONS: This study has shown the size of right dRA 2.27 + 0.39 mm in males and 2.09 + 0.38 mm in females. Diabetes, hypertension, height and weight are important predictors of dRA diameter.

BACKGROUND: Lack of health insurance is associated with adverse clinical outcomes; however, the association between health insurance status and in-hospital outcomes after out-of-hospital ventricular fibrillation (OHVFA) arrest is unclear. HYPOTHESIS: Lack of health insurance is associated with worse in-hospital outcomes after out-of-hospital ventricular fibrillation arrest. METHODS: From January 2003 to December 2014, hospitalizations with a primary diagnosis of OHVFA in patients ≥18 years of age were extracted from the Nationwide Inpatient Sample. Patients were categorized into insured and uninsured groups based on their documented health insurance status. Study outcome measures were in-hospital mortality, utilization of implantable cardioverter defibrillator (ICD), and cost of hospitalization. Inverse probability weighting adjusted binary logistic regression was performed to identify independent predictors of in-hospital mortality and ICD utilization and linear regression was performed to identify independent predictors of cost of hospitalization. RESULTS: Of 188 946 patients included in the final analyses, 178 005 (94.2%) patients were insured and 10 941 (5.8%) patients were uninsured. Unadjusted in-hospital mortality was higher (61.7% vs. 54.7%, p < .001) and ICD utilization was lower (15.3% vs. 18.3%, p < .001) in the uninsured patients. Lack of health insurance was independently associated with higher in-hospital mortality (O.R = 1.53, 95% C.I. [1.46-1.61]; p < .001) and lower utilization of ICD (O.R = 0.84, 95% C.I [0.79-0.90], p < .001). Cost of hospitalization was significantly higher in uninsured patients (median [interquartile range], p-value) ($) (39 650 [18 034-93 399] vs. 35 965 [14 568.50-96 163], p < .001). CONCLUSION: Lack of health insurance is associated with higher in-hospital mortality, lower utilization of ICD and higher cost of hospitalization after OHVFA.

In view of hemorrhagic and prothrombotic tendencies, ST-segment elevation myocardial infarction (STEMI) patients with chronic hematologic malignancies (CHM) are felt to be at a higher risk and hence denied standard reperfusion strategies. In-hospital outcomes of CHM patients presenting with STEMI are unclear. The Nationwide Inpatient Sample data files from 2003 to 2014 were used to extract adult patients who presented with a primary diagnosis of STEMI. Patients who had a diagnosis of CHM defined as chronic myelogenous leukemia, chronic lymphocytic leukemia, essential thrombocythemia, polycythemia vera, chronic monocytic leukemia, and multiple myeloma were identified. The primary study outcome measure was in-hospital mortality. Inverse probability weighting-adjusted binary logistic regression was performed to identify independent predictors of in-hospital mortality. Of 2,715,807 STEMI patients included in the final analyses, 11,974 (0.4%) patients had a diagnosis of CHM. Patients with CHM were significantly older, had a higher prevalence of co-morbidities, and had a significantly higher unadjusted in-hospital mortality (14.9% vs 9.0%; p <0.001). After adjusting for co-morbidities, CHM did not independently predict a higher in-hospital mortality (odds ratioâ¯=â¯1.02, 95% confidence intervalâ¯=â¯0.96 to 1.09; pâ¯=â¯0.461). In patients with CHM who presented with STEMI, percutaneous coronary intervention was found to be associated with a significant reduction in in-hospital mortality (odds ratioâ¯=â¯0.22, 95% confidence intervalâ¯=â¯0.18 to 0.27; p <0.001) (c-statisticâ¯=â¯0.81). In conclusion, CHM patients presenting with STEMI should be treated with similar treatment strategies as those without CHM, including revascularization if indicated, as there appears to be a sizable outcome advantage with this approach.

OBJECTIVES: To gain insight into current practice of transradial angiography and intervention in the United States and around the world. BACKGROUND: Transradial access (TRA) has grown worldwide. In a prior survey, there was significant practice variation and there was minimal US participation which limited the generalizability to US operators. METHODS: We used an internet-based survey software program to solicit input from practicing interventional cardiologists from the United States and around the world. US operators were compared with outside the United States (OUS) operators and respondent-level comparisons were made with the prior survey to assess for temporal changes in practice. RESULTS: Between August 2016 and January 1, 2017, 125 interventional cardiologists completed the survey representing 91 countries with the United States having 449 (39.9%) respondents. Preprocedure, noninvasive testing for collateral circulation is used more commonly in the United States (54.1%) than around the world (26.6%) but its use has decreased since 2010. In the US, 48.8% of operators never use ultrasound and 92.6% of OUS operators never use it; only 4.4% overall use ultrasound in >50% of cases. Use of bivalirudin has decreased in the US and OUS. Nearly, 30% of operators do not assess for radial artery patency following hemostasis. US respondents used TRA less commonly for primary PCI for STEMI than their global counterparts. CONCLUSIONS: There is wide variation in how TRA procedures are performed including relatively low rates of adherence to practices that are known to improve outcomes. Further education aimed at increasing use of best practices will impact patient outcomes.
