Relation of Multivessel Primary Percutaneous Coronary Intervention for ST-Elevation Myocardial Infarction to Outcome and/or Non-Infarct Artery Intervention of a Chronic Total Occlusion
We read with interest the recent report by Cavender et al, questioning the guidelines and use of multivessel percutaneous coronary intervention (PCI) in the setting of ST elevation myocardial infarction (STEMI). The investigators concluded that multivessel primary PCI for STEMI does not improve in-hospital outcomes, even in patients with cardiogenic shock. (Source: The American Journal of Cardiology)...

Differences in Patient Survival After Acute Myocardial Infarction by Hospital Capability of Performing Percutaneous Coronary Intervention: Implications for Regionalization [Original Investigation]
Conclusions The magnitude of benefit from comprehensively regionalizing AMI care to PCI hospitals appears to vary greatly across HRRs. These findings support a tailored regionalization policy that targets areas with the greatest outcome differences between PCI and local non-PCI hospitals. (Source: Archives of Internal Medicine)...

Vanishing platelets: rapid and extreme tirofiban-induced thrombocytopenia after percutaneous coronary intervention for acute myocardial infarction.
Authors: Rahman N, Jafary FH
Glycoprotein IIb/IIIa inhibitors are established treatment for patients who develop acute coronary syndromes. Thrombocytopenia is known to occur following the administration of various drugs, including heparin and glycoprotein IIb/IIIa inhibitors. In the case of glycoprotein IIb/IIIa inhibitors, the mechanism is thought to be drug-dependent antibodies. In most cases, the thrombocytopenia is mild or moderate in severity. Severe thrombocytopenia (platelet count, <50 x 109/L) is distinctly rare.Herein, we report a case of tirofiban-induced thrombocytopenia in which the overall platelet count dropped precipitously to <1 x 109/L within 12 hours of administration; recovery was relatively prolonged, possibly owing to concomitant renal insufficiency. The seve......

Revascularization options in patients with chronic kidney disease.
Authors: Ashrith G, Elayda MA, Wilson JM
Cardiovascular disease is the leading cause of death in patients who have chronic kidney disease or end-stage renal disease and are undergoing hemodialysis. Chronic kidney disease is a recognized risk factor for premature atherosclerosis. Unfortunately, most major randomized clinical trials that form the basis for evidence-based use of revascularization procedures exclude patients who have renal insufficiency. Retrospective, observational studies suggest that patients with end-stage renal disease and severe coronary occlusive disease have a lower risk of death if they undergo coronary revascularization rather than medical therapy alone. Due to a lack of prospective studies, however, the relative merits of percutaneous versus surgical revasculari......

Trends During 1993-2004 in the Availability and Use of Revascularization After Acute Myocardial Infarction in Markets Affected by Certificate of Need Regulations
This study examines trends in the diffusion of coronary artery bypass graft (CABG) and percutaneous coronary intervention (PCI) during 1993-2004 for patients with acute myocardial infarction in markets with and without Certificate of Need (CON) regulations for open-heart surgery or cardiac catheterization and in markets that repealed CON for either of these procedures. In contrast to prior studies, this study accounts for regional hospital markets that cross state boundaries—often with different CON activities in each state. The overall use of CABG increased modestly throughout the 1990s and subsequently decreased, corresponding to a dramatic increase in PCI. There was a greater rise in the number of CABG programs in markets with significant reduction in CON regulations during 1993-2......

Effects of stent implementation on plasma levels of asymmetric dimethylarginine in patients with or without ST-segment elevation acute myocardial infarction.
Authors: Ajtay Z, Németh A, Sulyok E, Cziráki A, Szabados S, Martens-Lobenhoffer J, Awiszus F, Szabó C, Bode-Böger SM
The study was designed to compare the response pattern of plasma l-arginine and methylarginines to stent placement in patients with or without ST segment elevation myocardial infarction (STEMI). Two groups of patients with obstructive coronary artery disease (OCAD) undergoing percutaneous coronary intervention (PCI) with stenting were enrolled in the study. Group I consisted of 16 patients with STEMI, whereas group II included 24 patients without STEMI (controls). Before PCI and at <1 h, 5 and 30 days after reperfusion, blood samples were taken for measurement of l-arginine and methylarginines. L-arginine, asymmetric dimethylarginine (ADMA), symme......

Does Inability To Express Emotions Affect Outcome Of Coronary Angioplasty?
A French investigation published in the current issue of Psychotherapy and Psychosomatics has explored the outcome in terms of physical functioning of coronary angioplasty. Although anxiety and depressive symptoms have been reported to be predictive of poorer functional recovery in coronary heart disease (CHD) patients, little data are available on their effects after percutaneous transluminal coronary angioplasty (PTCA). Alexithymia is a psychological construct that encompasses a deficiency in understanding, processing, or describing emotions... (Source: Health News from Medical News Today)...

Real World, Long-Term Outcomes Comparison Between Paclitaxel-Eluting and Sirolimus-Eluting Stent Platforms
We compare real-world, extended target vessel revascularization (TVR)-free survival following percutaneous coronary intervention (PCI) for patients receiving either sirolimus-eluting stents (SES) or paclitaxel-eluting stents (PES) following an index drug-eluting stent (DES) supported procedure. We analyzed 2,363 consecutive patients having first DES-supported PCI at receiving PES (n = 1,012) or SES (n = 1,332) from April 2004 to July 2006. Baseline clinical and procedural characteristics and in-hospital outcomes were recorded during the time of the index procedure and extended clinical outcomes data were obtained thereafter. TVR and all cause mortality were identified during the study period. Adjusted Kaplan-Meier and Cox's proportional hazard survival methods were performed. TVR-free surv......

Safety and effectiveness of bivalirudin in routine care of patients undergoing PCI
Source: Eur Heart J
Area: News
Recent trials have found that bivalirudin is non-inferior to heparin with respect to death and repeat revascularisation, with a decrease in the risk of major bleeds. However, the use of bivalirudin in the context of routine care has not been evaluated.
To further investigate, researchers identified 127 185 individuals from a US cohort of patients who underwent inpatient percutaneous coronary intervention (PCI) between June 2003 and December 2006 and were administered either bivalirudin plus provisional glycoprotein IIb/IIIa inhibitor (GPI) or heparin (at least 1000 units) plus GPI. The primary outcome was blood transfusions, as represented in the database by order of any blood product.
