Fibrinolytic therapy is the most common reperfusion strategy for patients with ST-segment elevation myocardial infarction (STEMI), particularly in smaller centers. Previous studies evaluated the relation between time to treatment and outcomes when few patients were treated within 30 minutes of hospital arrival and many did not receive modern adjunctive medications. To quantify the impact of a delay in door-to-needle time on mortality in a recent and representative cohort of patients with STEMI, a cohort of 62,470 patients with STEMI treated using fibrinolytic therapy at 973 hospitals that participated in the National Registry of Myocardial Infarction from 1999 to 2002 was analyzed. Hierarchical models were used to evaluate the independent effect of door-to-needle time on in-hospital mortality. In-hospital mortality was lower with shorter door-to-needle times (2.9% for < or =30 minutes, 4.1% for 31 to 45 minutes, and 6.2% for >45 minutes; p <0.001 for trend). Compared with those experiencing door-to-needle times < or =30 minutes, adjusted odd ratios (ORs) of dying were 1.17 (95% confidence interval [CI] 1.04 to 1.31) and 1.37 (95% CI 1.23 to 1.52; p for trend <0.001) for patients with door-to-needle times of 31 to 45 and >45 minutes, respectively. This relation was particularly pronounced in those presenting within 1 hour of symptom onset to presentation time (OR 1.25, 95% CI 1.01 to 1.54; OR 1.54, 95% CI 1.27 to 1.87, respectively; p for trend <0.001). In conclusion, timely administration of fibrinolytic therapy continues to significantly impact on mortality in the modern era, particularly in patients presenting early after symptom onset. 相似文献

The guidelines of the European Society of Cardiology, published in 2003, consider primary angioplasty as the preferred treatment strategy in acute coronary syndromes with ST-segment elevation, if the procedure can be performed within 90 min after first medical contact. We report the experience of three Alsacian centers running a common prospective registry with 2504 consecutive patients enroled between January 1999 and December 2004. The average age of the patients was 62 years with a proportion of 24% women. The time delay "pain to admission" was > or =3 hours in 55.9% of the cases. The treatment delay "door to catheterisation needle" was 59 min and the mean delay "door-to-reperfusion" was 79 min. The study population was representative of the real world including subsets of patients with a particulary high risk profile: age > or =70 years in 33%, a Killip grade > or =3 in 11.5%, rescucitated sudden death in 6.6% and cardiogenic shock in 10.9% of the patients respectively. The immediate procedural success rate (Timi 3 flow) in the treated coronary artery was 96.5%. The overall inhospital mortality-rate was 9.3%. The combinations of rescucitated sudden death--cardiogenic shock or age > or =75 years--cardiogenic shock were associated with a poor clinical outcome and mortality rates of 69% and 72.6% respectively, where as in the absence of abovementioned clinical high risk settings, the mortality rate was as low as 1.4%. The overall bleeding complication rate was 1.4%. The policy of systematic primary angioplasty in acute coronary syndromes with ST-Segment elevation appears to be coherent. The procedural complications and the in-hospital mortality rates were low, except in the presence of above mentioned clinical high risk settings. 相似文献

The aim of the present study was to evaluate the additional prognostic effect of ST-depression resolution in 610 patients who had ST-elevation myocardial infarction and underwent successful primary angioplasty (postprocedural Thrombolysis In Myocardial Infarction 3 flow and complete resolution of ST-segment elevation). Incomplete resolution of ST-segment depression (<70%) was observed in 50 patients (8.2%). These patients were older, had a higher Killip's class at presentation, had larger infarcts, and had an increased 1-year mortality (10% vs 2%, p = 0.0004). At multivariate analysis, incomplete resolution of ST-segment depression was an independent predictor of 1-year mortality (p = 0.028). 相似文献

Symptom-onset-to-balloon time and mortality in patients with acute myocardial infarction treated by primary angioplasty 总被引:27,自引:0,他引:27
De Luca G Suryapranata H Zijlstra F van 't Hof AW Hoorntje JC Gosselink AT Dambrink JH de Boer MJ;ZWOLLE Myocardial Infarction Study Group 《Journal of the American College of Cardiology》2003,42(6):991-997
OBJECTIVES: The aim of the study was to evaluate the relationship between symptom-onset-to-balloon time and one-year mortality in patients with ST-segment elevation myocardial infarction (STEMI) treated by primary angioplasty. BACKGROUND: Despite the prognostic implications demonstrated in patients with STEMI treated with thrombolysis, the impact of time-delay on prognosis in patients undergoing primary angioplasty has yet to be established. METHODS: Our study population consisted of 1,791 patients with STEMI treated by primary angioplasty from 1994 to 2001. All clinical, angiographic and follow-up data were collected. Subanalyses were conducted according to patient risk profile at presentation and preprocedural Thrombolysis In Myocardial Infarction (TIMI) flow. RESULTS: A total of 103 patients (5.8%) had died at one year. Symptom-onset-to-balloon time was significantly associated with the rate of postprocedural TIMI 3 flow (p = 0.012), myocardial blush grade (p = 0.033), and one-year mortality (p = 0.02). A stronger linear association between symptom-onset-to-balloon time and one-year mortality was observed in non-low-risk patients (p = 0.006) and those with preprocedural TIMI flow 0 to 1 (p = 0.013). No relationship was found between door-to-balloon time and mortality. At multivariate analysis, a symptom-onset-to-balloon time >4 h was identified as an independent predictor of one-year mortality (p < 0.05). CONCLUSIONS: This study shows that, in patients with STEMI treated by primary angioplasty, symptom-onset-to-balloon time, but not door-to-balloon time, is related to mortality, particularly in non-low-risk patients and in the absence of preprocedural anterograde flow. Furthermore, a symptom-onset-to-balloon time >4 h was identified as independent predictor of one-year mortality. 相似文献

Ageing, impaired myocardial perfusion, and mortality in patients with ST-segment elevation myocardial infarction treated by primary angioplasty. 总被引:2,自引:0,他引:2

AIMS: It is still unknown whether impaired myocardial perfusion helps to explain the higher mortality observed with ageing in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary angioplasty. METHODS AND RESULTS: In 1548 consecutive patients with STEMI treated with primary angioplasty, myocardial perfusion was evaluated by myocardial blush grade (MBG) and ST-segment resolution. All clinical and follow-up data were prospectively collected. Advanced age was associated with a significantly higher clinical and angiographic risk profile. We found a linear relationship between increasing age, decreased myocardial perfusion, and higher 1-year mortality. After adjustment for baseline potential confounding variables, increased age was still significantly associated with impaired myocardial blush (MBG 0-1) (P=0.028), and ST-segment resolution (<50%) (P=0.007). At multivariable analysis both age (P<0.0001) and poor myocardial perfusion (P<0.0001) were independent predictors of 1-year mortality. CONCLUSION: This study shows that impaired reperfusion is an additional determinant of the poor outcome observed with advanced age in patients with STEMI undergoing mechanical revascularization. 相似文献

The aim of the present study was to evaluate the impact of interhospital delay on mortality in 616 patients with ST-segment elevation myocardial infarction transferred for primary angioplasty to our hospital. Longer interhospital delay was associated with impaired perfusion, larger infarct size, and higher 1-year mortality (adjusted RR 1.5, 95% confidence interval 1.07 to 2.12; p = 0.019). These results suggest that in patients with ST-segment elevation myocardial infarction transferred for primary angioplasty, all efforts should be made to reduce time to treatment. 相似文献

This study analyzed the effect of beta-blocker therapy at discharge on 1-year mortality rate in a large, unselected cohort of patients who had ST-segment elevation myocardial infarction that was treated by primary angioplasty. Our population is represented by 1,513 patients. At 1-year follow-up, beta blockers at discharge were associated with a significant decrease in mortality rate (2.9% vs 8.5%, RR 0.33, 95% confidence interval [CI] 0.18 to 0.59, p <0.0001), particularly in patients who had anterior wall infarction (3.9% vs 13.4%, RR 0.28, 95% CI 0.14 to 0.54, p <0.0001), whereas nonsignificant benefits were observed in patients who had nonanterior wall infarction (2.0% vs 3.3%, RR 0.6, 95% CI 0.17 to 2.07, p = NS). Benefits in terms of mortality rate that were conferred by beta blockers were confirmed at multivariate analysis that was restricted to patients who had anterior wall infarction (RR 0.43, 95% CI 0.21 to 0.86, p = 0.022). 相似文献

Pharmacological treatment is essential to limit myocardial damages of occluding thrombus feature of acute coronary syndromes with persistent ST-segment elevation. Thanks to its ease of use, it will always come first and accompany a mechanical treatment that will complement its action. Research has been very active in the last few years allowing the development of new agents, mostly oral antiplatelets and intravenous or subcutaneous antithrombins. Physicians implied in strategies of reperfusion have a responsibility to choose the most suitable combination therapy taking into account delays in care, kind of reperfusion and the patient himself. The highest level of recommendation indicative of a perfect agreement of the experts is rare in this area. Therefore, guidance is needed to help physicians. Admittedly the latest European recommendations merit of having taken positions often clear when several molecules are available in the same indication. They also underline the arrival, unexpected a few years ago, of oral treatment with rapid onset and efficacy perfectly suited to start an emergency antithrombotic treatment in acute coronary syndromes with persistent ST-segment elevation. Nevertheless, progress in terms of clinical efficacy is often modest, requiring a concomitant evaluation of each new molecule's safety, particularly the risks of bleeding. 相似文献
