BACKGROUND The access to and growth of percutaneous coronary intervention (PCI) has not been fully explored with regard to geographic equity and need. Economic factors and timely access to primary PCI provide the impetus for growth in PCI centers, and this is balanced by volume standards and the benefits of regionalized care. METHODS AND RESULTS Geospatial and statistical analyses were used t...

BACKGROUND Evidence suggests that coronary heart disease (CHD) is associated with increased anxiety and a high incidence of comorbid anxiety and depression. However, the association between percutaneous coronary intervention (PCI) and comorbid anxiety and depression has not been previously investigated. This study aims to determine the relationship between PCI and anxiety and depression symptom...

AIMS We sought to characterize the outcomes of patients with a prior percutaneous coronary intervention (PCI) who presented with a non-ST-segment elevation acute coronary syndrome (ACS). METHODS AND RESULTS We analysed the 30 and 180 day outcomes of 3012 patients with prior PCI and 21 154 patients without prior PCI enrolled in three randomized ACS trials (GUSTO IIb, PURSUIT, and PARAGON-B). T...

Hospital transfer is associated with delays in performance of primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction. Given the limited number of interventional centers in the United States, the transfer of patients is widely practiced. We compared the outcome of patients who were transferred for primary PCI and determined whether prolonged door-to-balloon times...

background: this study was designed to examine a unique and low dose use of intravenous enoxaparin in elective percutaneous coronary intervention (pci) that would be applicable to an unselected population regardless of age, weight, and renal function. there is limited experience in anticoagulation using intravenous low-molecular-weight heparin in pci. methods: a total of 100 consecutive patient...

Coronary artery disease (CAD) is a life-threatening medical emergency which needs urgent medical attention. Percutaneous coronary intervention (PCI) is common and necessary for patients with CAD, but it has not completely evaluated in cases with repeated PCI. Therefore, the aim of this study was to examine the risk factors and prognosis in patients with CAD requiring repeated PCI. This is a pro...

To leverage high speed interconnects like InfiniBand it is important to minimize the communication overhead. The most interfering overhead is the registration of communication memory. In this paper, we present our analysis of the memory registration process inside the Mellanox InfiniBand driver and possible ways out of this bottleneck. We evaluate and characterize the most time consuming parts ...

State-of-the-art FPGAs are just capable of implementing PCI bus initiator and target functions at the original bus speed of 33 MHz. This paper reports on the use of a Xilinx 4000 series FPGA and LogiCore macros to implement a fully compliant PCI card for a specialist data acquisition application. The design required careful performance analysis and manual intervention during the design process ...

Speed humps used as a tool of traffic calming technique that applied to force drivers to reduce their vehicle’ speeds at some locations. For developed countries, the implementations of speed humps are often used within residential areas as well as at locations of schools crossing.  For developing countries (e.g. Iraq), speed humps are used even at urban and urban highways.   This paper investig...

Background: Patients having percutaneous coronary intervention (PCI) and angiography (CAG) are more likely to experience contrast-induced nephropathy (CIN), which is linked higher mortality morbidity (PCI). Our goal was assess the effectiveness of nicorandil medication given patients getting ready for elective PCI in reducing occurrence CIN.
