Abstract

BACKGROUND: Among Medicare value-based payment programs for acute myocardial infarction (AMI), the Hospital Readmissions Reduction Program (HRRP) uses ICD-10 codes to identify the program denominator, while the Bundled Payments for Care Improvement Advanced (BPCIA) program uses DRGs. The extent to which these programs target similar patients, whether they target the intended population (Type 1 myocardial infarction), and whether outcomes are comparable between cohorts is not known. METHODS: In a retrospective study of 2,176 patients hospitalized in an integrated health system, a cohort of patients assigned a principal ICD-10 diagnosis of AMI and a cohort of patients assigned an AMI DRG were compared according to patient-level agreement and outcomes such as mortality and readmission. RESULTS: 1,935 patients were included in the ICD-10 cohort compared to 662 patients in the DRG cohort. Only 421 patients were included in both AMI cohorts (19.3% agreement). DRG cohort patients were older (70 vs. 65 years, p

77. Association between use of bleeding avoidance strategies and risk of periprocedural bleeding among patients undergoing percutaneous coronary intervention

Abstract

A study was conducted to evaluate the relationship between the use of bleeding avoidance strategies and risk of periprocedural bleeding among patients undergoing percutaneous coronary intervention. Results indicated that vascular closure devices and bivalirudin were associated with significantly lower bleeding rates; however, were less often used among high-risk patients.

85. Contraindicated medication use in dialysis patients undergoing percutaneous coronary intervention

Abstract

The study attempts to evaluate the efficacy and safety of contraindicated medications like enoxaparin and eptifibatide among dialysis patients undergoing percutaneous coronary intervention (PCI). The results indicate that in many cases use of such drugs led to an increased risk of in-hospital major bleeding.

Abstract

BACKGROUND: Restricting TAVR to centers based on volume thresholds alone can potentially create unintended disparities in healthcare access. We aimed to compare the influence of population density in state of Florida in regard to access to TAVR, TAVR-utilization rates, and in-hospital mortality. METHODS AND RESULTS: From 2011–2016, we used data from the AHCA to calculate travel time and distance for each TAVR-patient by comparing their home address to their TAVR-facility ZIP-code. Travel time and distance, TAVR rates, and mortality were compared across categories of low to high population density (population per sq. mi of land). Of the 6,531 patients included, the mean (SD) age was 82 (9) years, 43% were female and 91% were Caucasian. Patients residing in the lowest category (

99. Quantitative analysis of reconstructed 3-D coronary arterial tree and intracoronary devices

Abstract

Traditional quantitative coronary angiography is performed on two-dimensional (2-D) projection views. These views are chosen by the angiographer to minimize vessel overlap and foreshortening. With 2-D projection views that are acquired in this nonstandardized fashion, however, there is no way to know or estimate how much error occurs in the QCA process. Furthermore, coronary arteries possess a curvilinear shape and undergo a cyclical deformation due to their attachment to the myocardium. Therefore, it is necessary to obtain three-dimensional (3-D) information to best describe and quantify the dynamic curvilinear nature of the human coronary artery. Using a patient-specific 3-D coronary reconstruction algorithm and routine angiographic images, a new technique is proposed to describe: 1) the curvilinear nature of 3-D coronary arteries and intracoronary devices; 2) the magnitude of the arterial deformation caused by intracoronary devices and due to heart motion; and 3) optimal view(s) with respect to the desired 'pathway' for delivering intracoronary devices. Index Terms--3-D reconstruction, angiography, angioplasty, intracoronary devices, vasculature.
