Prognostic risk prediction models have been employed in the intensive care unit (ICU) setting since the 1980s and provide health care providers with important information to help inform decisions related to treatment and prognosis, as well as to compare outcomes across institutions. Prognostic models for critical care are among the most widely utilized and(More)
Support vector machines (SVM) have become popular among machine learning researchers, but their applications in biomedicine have been somewhat limited. A number of methods, such as grid search and evolutionary algorithms, have been utilized to optimize model parameters of SVMs. The sensitivity of the results to changes in optimization methods has not been(More)
Vascular closure devices offer advantages over traditional means of obtaining hemostasis after percutaneous coronary intervention (PCI) in terms of patient comfort and time to ambulation. We investigate whether such devices also reduce the risk of vascular complications in selected patient populations. We conducted a retrospective analysis of all patients(More)

BACKGROUND No-reflow occurring during percutaneous coronary intervention (PCI) has been associated with poor inhospital outcomes. The objectives of this analysis were to evaluate the occurrence of no-reflow as an independent predictor of adverse events and to determine whether treatment with intracoronary vasodilator therapy affected clinical outcomes.

BACKGROUND Complications of vascular access are one of the most common adverse events after coronary angiography and percutaneous coronary intervention (PCI) and are reported to occur in 1% to 9% of cases. There are conflicting reports of the association of vascular complications with the use of vascular closure devices (VCDs). The purpose of this study was(More)
The Angio-Seal vascular closure device has been shown to be safe and effective in decreasing the time to hemostasis after percutaneous coronary intervention (PCI). The health economic implications of routinely using Angio-Seal after PCI have not been explored. We performed a cost-minimization analysis comparing routine Angio-Seal use after PCI with(More)
Bleeding complications after coronary intervention are associated with prolonged hospitalization, increased hospital costs, patient dissatisfaction, morbidity, and 1-year mortality. Bleeding avoidance strategies is a term incorporating multiple modalities that aim to reduce bleeding and vascular complications after cardiovascular catheterization. Recent(More)
iDASH (integrating data for analysis, anonymization, and sharing) is the newest National Center for Biomedical Computing funded by the NIH. It focuses on algorithms and tools for sharing data in a privacy-preserving manner. Foundational privacy technology research performed within iDASH is coupled with innovative engineering for collaborative tool(More)
In this retrospective review of 5,234 cardiac catheterizations and percutaneous coronary interventions, the rate of vascular complications was highest in extremely thin and morbidly obese patients and lowest in moderately obese patients, consistent with the previously reported "obesity paradox." The use of transradial access and arterial access closure(More)
