Recurrent Myocardial Infarction (recurrent + myocardial_infarction)
Selected AbstractsEstimating nurses' workload using the Diagnosis Procedure Combination in JapanINTERNATIONAL NURSING REVIEW, Issue 3 2008Y. Kamijo rn Aim:, To examine the methods used to estimate nurse staffing levels in acute care settings with Diagnosis Related Groups, which in Japan are called the Diagnosis Procedure Combination (DPC). Methods:, For estimating staffing requirements, the study used four DPC groups: (1) acute or recurrent myocardial infarction (AMI) with stenting, (2) angina pectoris with coronary artery bypass grafting (CABG), (3) sub-arachnoid haemorrhage (SAH) with clipping surgery, and (4) cerebral infarction with carotid endarterectomy (CEA). Registered nurses with more than 3-year nursing experience in nine university hospitals in the Tokyo metropolitan area completed self-report questionnaires in order to obtain nursing care time and care intensity per each DPC. The concordance rate was measured by Kendall's coefficient of concordance. The relationship between the care time and the care intensity was examined by a time series graph per DPC. Care intensity consisted of professional judgement, mental effort for helping patients, professional skill, physical effort for providing activities of daily living support, and nurse stress, based on the Hsiao and colleagues' model of resource-based relative value scale. Results:, Twenty-five nurses in nine university hospitals answered for a hypothetical typical patient with AMI and with CABG, and 28 nurses in nine university hospitals answered for a hypothetical typical patient with SAH and with CEA. Kendall's coefficient of concordance was 0.896 for AMI, 0.855 for CABG, 0.848 for SAH, 0.854 for CEA. The time series data of the care time and the care intensity items showed different patterns for each DPC. Conclusion:, The DPC for cardiovascular and cerebral surgical procedures can be used for estimating nurses' workload.

MCCULLOUGH M.D. Patients with acute coronary syndromes who are considered ineligible for thrombolytic therapy are at high risk of recurrent ischemia and death. This trial randomized 201 patients to triage angiography in the first 24 hours of hospital admission versus conventional medical care. Of the 165 patients who underwent angiography that was either protocol-driven or on the basis of physician preference, those who underwent angiography within 6 hours of symptom onset had a reduction in early and late adverse events. The rates of in-hospital recurrent ischemia were 15.4%, 15.4%, 17.5%, 32.4%, and 38.5%, respectively (P = 0.01 for trend), and rates of cumulative recurrent myocardial infarction or death were 0%, 12.8%, 10.0%, 11.8%, and 7.7%, respectively (P = 0.48 for trend) for patients who underwent angiography at 0,6, 6,12, 12,24, 24,48, and over 48 hours, respectively from symptom onset. Future trials of invasive versus conservative therapy should focus on performing angiography within 6 hours of symptom onset.

Iri Kupferwasser MD Abstract Objectives: The aim of this study was to compare the procedural characteristics and outcomes of patients with acute myocardial infarction treated with drug-eluting stents (DES) vs. bare metal stents (BMS). Background: DES have been shown to reduce the incidence of restenosis and target vessel revascularization (TVR) in clinical randomized studies when compared with BMS in patients undergoing elective percutaneous intervention. Limited data are available with the use of DES in patients with acute ST-segment elevation myocardial infarction. Methods: Two hundred and sixty-one consecutive patients who presented with myocardial infarction between 7/2001 and 8/2005 were studied. The procedural characteristics, 30-day and 12-month outcomes of 131 patients treated with DES were compared with 130 patients treated with BMS. Results: At 12-months follow-up DES therapy was associated with a substantial decrease in major adverse cardiovascular events (MACE) (HR 0.33; P =0.002), TVR (HR 0.19; P =0.002), and recurrent myocardial infarction (HR 0.23; P =0.051) vs. BMS therapy. Coronary interventions utilizing DES were characterized by a marked increase in the number of stent per target vessel (DES: 1.9 ± 0.9 vs. BMS: 1.38 ± 0.6, P < 0.0001), treatment of bifurcation (DES: 21% vs. BMS: 5%, P =0.0004), and multivessel intervention (DES: 22% vs. BMS: 8%, P =0.003). Conclusion: The routine use of DES in acute myocardial infarction is associated with reduced rates of MACE at 12 months vs BMS, despite a higher rate of complex procedures in the DES treated patients. In addition to its anti-restenosis effect, the improved outcome of patients treated with DES may be linked to a more complete revascularization in association with prolonged clopidogrel therapy. © 2007 Wiley-Liss, Inc. [source] Adjunctive Low Molecular Weight Heparin During Fibrinolytic Therapy in Acute ST-Segment Elevation Myocardial Infarction: A Meta-Analysis Of Randomized Control TrialsCLINICAL CARDIOLOGY, Issue 7 2009Sarabjeet Singh MD Background Recent data suggests that low molecular weight heparins (LMWHs) may be superior to unfractionated heparin (UFH) as an adjunct to fibrinolytic therapy in patients with acute ST-segment elevation myocardial infarction (STEMI). Hypothesis We evaluated cardiac outcomes and the risk of major bleeding with LMWHs vs UFH in the management of STEMI. Methods Seven randomized trials of patients with acute STEMI treated with fibrinolytic therapy and adjunctive LMWHs through the index hospitalization or weight-based UFH for at least 48 hours were identified. We analyzed both primary endpoints (death and nonfatal recurrent myocardial infarction through 30 days), and secondary endpoints (death, recurrent myocardial infarction, and major bleeding during index hospitalization at 7 days). Outcomes were computed using the Mantel-Haenszel fixed-effect model. A 2-sided alpha error of < 0.05 was considered significant. Results Compared to UFH, LMWH significantly reduced reinfarction (p < 0.001) during hospitalization at 7 days and the effect remained consistent at 30 d (p < 0.001). When analyzed for mortality at 7 days and 30 days follow-up, there were no statistically significant differences observed between the 2 groups. Additionally the LMWH group had higher risk of major bleeding (p < 0.001). Conclusions The present meta-analysis suggests in patients receiving fibrinolytic therapy for STEMI, LMWHs as an adjunctive therapy is superior to UFH in reducing reinfarction during hospitalization at 7 days and at 30 days. The mortality was not significant between the 2 groups during hospitalization at 7 days and at 30 days. However, UFH is superior to LMWHs in the reduction of major bleeding at 7 days index hospitalization. Copyright © 2009 Wiley Periodicals, Inc. [source] | ||||||||||
