Cystatin C is a marker of renal dysfunction, and preliminary studies have suggested it might have a role as a prognostic marker in patients with coronary artery disease. The aim of the present study was to evaluate the usefulness of cystatin C for risk stratification of patients with ST-segment elevation myocardial infarction, regarding in-hospital and long-term outcomes. We included 153 consecutive patients with ST-segment elevation myocardial infarction treated by primary angioplasty. The baseline cystatin C level was measured at coronary angiography. The in-hospital outcome was determined as progression to cardiogenic shock or in-hospital death, and the long-term outcome was assessed, considering the following end points: (1) death and (2) death or reinfarction. Of the 153 patients evaluated (age 61 ± 12 years; 75.6% men), 15 (14.4%) progressed to cardiogenic shock and 4 (2.7%) died during hospitalization. The patients who progressed to cardiogenic shock or died during hospitalization had significantly greater cystatin C levels (1.02 ± 0.44 vs 0.69 ± 0.24 mg/L; p = 0.001). Long-term follow-up was available for 130 patients (583 ± 163 days). Among them, 11 patients died and 7 had reinfarction. A high baseline cystatin C level was associated with an increased risk of death (hazard ratio 8.5; p = 0.009) and death or reinfarction (hazard ratio 3.89; p = 0.021). Furthermore, only high baseline cystatin C levels and left ventricular ejection fraction ≤40% were independent predictors of the long-term risk of death, with synergistic interaction between the 2. In conclusion, cystatin C is a new biomarker with significant added prognostic value for patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention, predicting both short- and long-term outcomes.  相似文献

The aim of this study was to investigate the incidence of composite short-term and long-term major adverse upper gastrointestinal (UGI) events (MAUGIEs; defined as gastric ulcer, duodenal ulcer, gastroduodenal ulcer, or UGI bleeding) in patients with acute ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and routinely received dual-antiplatelet therapy. From May 2002 to September 2010, a total of 1,368 consecutive patients who experienced ST-segment elevation myocardial infarction and underwent primary percutaneous coronary intervention were prospectively enrolled in the study. The incidence of in-hospital UGI bleeding complications and composite MAUGIEs was 8.9% and 9.9%, respectively. The in-hospital mortality rate was significantly higher in patients with in-hospital MAUGIEs than in those without (p <0.001). Multivariate analysis showed that age, advanced Killip score (≥3), and respiratory failure were the strongest independent predictors of in-hospital composite MAUGIEs (all p <0.003). The cumulative composite of MAUGIEs after uneventful discharge in patients without adverse UGI events who continuously received dual-antiplatelet therapy for 3 to 12 months, followed by aspirin therapy, was 10.4% during long-term (mean 4.0 years) follow-up. In conclusion, the results of this study show a remarkably high incidence of composite short-term and long-term MAUGIEs in patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and received routine dual-antiplatelet therapy. Age, advanced Killip score, and respiratory failure were significantly and independently predictive of in-hospital composite MAUGIEs.  相似文献

目的探讨急诊冠状动脉介入术(PC I)后ST段恢复程度对急性心肌梗死(AM I)患者早期预后的影响。方法452例AM I患者根据其术后ST抬高程度分为3组:ST抬高<1.0 mm组(210例),ST抬高1.02.0 mm组(178例)以及ST段抬高>2.0 mm组(64例),分析3组患者住院期间再次发生AM I、恶性心律失常、泵衰竭和死亡的情况。结果随着ST段抬高幅度增加,3组患者的泵衰竭发生率分别为6.7%、12.9%和17.2%(P<0.05),恶性心律失常发生率分别为2.9%、5.1%和12.5%(P<0.05),院内病死率分别为1.4%、3.9%和9.4%(P<0.05)及急性心肌再梗死率分别为0%、2.2%和4.7%(P<0.05)。分析显示术后单导联ST段抬高幅度是院内不良事件发生的最强独立预测因素[OR=2.42,95%C I:(1.174.02),P<0.01]。结论单导联ST段抬高幅度是划分急诊PC I术后早期预后危险分层的一种简单有效的方法。  相似文献

The aim of the present study was to evaluate the effect of concurrent chronic total occlusion (CTO) in a noninfarct-related artery (IRA) on the long-term prognosis in patients with ST-segment elevation myocardial infarction and multivessel coronary disease. Of 1,658 consecutive patients with ST-segment elevation myocardial infarction, 666 with multivessel coronary disease who underwent percutaneous coronary intervention from 1999 to 2004 were included in the present analysis. The patients were divided into 2 groups: no CTO and CTO. The first group included 462 patients without CTO (69%) and the second group included 204 patients with CTO in a non-IRA (31%). The in-hospital mortality rate was 6.3% and 21.1% (p < 0.0001) and the 5-year mortality rate was 22.5% and 40.2% (p < 0.0001) for the no-CTO and CTO patients, respectively. Multivariate analysis revealed that after correction for baseline differences CTO in a non-IRA was a strong, independent predictor of 5-year mortality in patients undergoing percutaneous coronary intervention (hazard ratio 1.85; 95% confidence interval 1.35 to 2.53; p = 0.0001). In conclusion, the presence of CTO in a non-IRA in patients with ST-segment elevation myocardial infarction and multivessel coronary disease is a strong and independent risk factor for greater 5-year mortality.  相似文献

With the growing understanding of the role of inflammation in patients with atherosclerotic disease, studies have focused on high-sensitivity C-reactive protein (hs-CRP) and other inflammatory markers in their association with outcomes in ST-segment elevation myocardial infarction. The goal of this study was to investigate the association of the neutrophil/lymphocyte (N/L) ratio and in-hospital major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI). The association of hs-CRP and N/L ratio on admission with Thrombolysis In Myocardial Infarction (TIMI) flow grade after PCI was assessed in 418 consecutive primary patients with PCI. The N/L ratio was significantly higher in the no-reflow group (TIMI grade 0/1/2 flow, n = 158) compared to that of the normal-flow group (TIMI grade 3 flow, n = 260, 4.6 ± 1.7 vs 3.1 ± 1.9, p <0.001). In-hospital MACEs were significantly higher in patients with no reflow (23% vs 7%, p <0.001). There was a significant and positive correlation between hs-CRP and N/L ratio (r = 0.657, p <0.001). In receiver operating characteristic analysis, N/L ratio >3.3 predicted no reflow with 74% sensitivity and 83% specificity. In a multivariate regression model, N/L ratio remained an independent correlate of no reflow (odds ratio [OR] 1.54, 95% confidence interval [CI] 1.34 to 1.76, p <0.001) and in-hospital MACEs (OR 1.14, 95% CI 0.98 to 1.32, p = 0.043). The N/L ratio, an inexpensive and easily measurable laboratory variable, is independently associated with the development of no reflow and in-hospital MACEs in patients with ST-segment elevation myocardial infarction undergoing primary PCI.  相似文献

AimsAssessment of the diversity in the no-reflow population after primary percutaneous coronary intervention (pPCI) due to ST-segment elevation myocardial infarction (STEMI). Are there any gender-related differences?Material and methodsAnalysis of 1063 STEMI patients with Thrombolysis in Myocardial Infarction (TIMI) grade 0 or 1 following pPCI. The study group consisted of 685 patients with TIMI grade 0 and of 378 patients with TIMI grade 1. We analyzed clinical characteristics, in-hospital mortality and 2-year follow-up in both groups.ResultsAmong women with the TIMI grade 1 an atrial fibrillation, tachycardia and impaired ejection fraction were more common than in men. The vessel responsible for myocardial infarction was most commonly the left anterior descending (LAD) in women, whereas the right coronary artery (RCA) in men. These differences were not observed in group with TIMI grade 0. We observed a higher incidence of in-hospital death in the population with TIMI grade 0 compared with TIMI grade 1 (21.9% vs 17.2%; p 0.0189). In the TIMI grade 1 group there was significantly higher incidence of in-hospital mortality in women compared to men (13.2% vs 22.7%; p 0,0159). Among women with postprocedural TIMI grade 0 in all periods of long-term follow-up the mortality was significantly higher compared to men (9.5% vs 17%; p 0,0111; 11.8% vs 19.7%; p 0.0139 and 16.7% vs 23.9%; p 0.043 for 6-,12-months and 2-years of follow up respectively).ConclusionsPatients with no-reflow phenomenon in infarct related artery after pPCI constitute a more diverse group than previously thought. Some differences are most likely gender-specific. The female sex might have an adverse effect on in-hospital mortality in case of TIMI grade 1 and on the long-term prognosis among patients with TIMI grade 0.  相似文献

The aim of the present study was to compare 600- and 300-mg clopidogrel loading doses in patients with ST-segment elevation myocardial infarctions who underwent primary percutaneous coronary intervention (PCI). Two hundred fifty-five consecutive patients presenting with ST-segment elevation myocardial infarctions who underwent primary PCI were enrolled. Patients were divided into 2 groups on the basis of the loading dose of clopidogrel received before the procedure (600 vs 300 mg). Procedural angiographic end points and 1-year major adverse cardiac events were compared between the 2 groups. Major adverse cardiac events were defined as death, nonfatal myocardial infarction, and target vessel revascularization. There were no significant differences in baseline clinical and angiographic features between the 2 groups: 157 (62%) in the clopidogrel 600 mg group and 98 (38%) in the 300 mg group. Patients receiving 600-mg loading dose of clopidogrel showed a significantly lower incidence of post-PCI myocardial blush grade 0 or 1 (odds ratio 0.64, 95% confidence interval 0.43 to 0.96, p = 0.03) and significantly less common no-reflow phenomenon (odds ratio 0.38, 95% confidence interval 0.15 to 0.98, p = 0.04) compared to those in the 300-mg group. Propensity-adjusted Cox analysis showed significantly higher survival free of major adverse cardiac events in patients receiving 600-mg loading dose of clopidogrel compared to those receiving the lower dose (hazard ratio 0.57, 95% confidence interval 0.33 to 0.98, p = 0.04). In conclusion, a 600-mg loading dose of clopidogrel is associated with improvements in procedural angiographic end points and 1-year clinical outcomes in patients with ST-segment elevation myocardial infarction who undergo primary PCI compared to a 300-mg dose.  相似文献

Objective Admission hyperglycemia in acute myocardial infarction (MI) is related with increased in-hospital and long term mortality and major cardiac adverse events. We aimed to investigate how admission hyperglycemia affects the short and long term outcomes in elderly patients (> 65 years) after primary percutaneous coronary intervention for ST elevation myocardial infarction. Methods We retrospectively analyzed 677 consecutive elderly patients (mean age 72.2 ± 5.4). Patients were divided into two groups according to admission blood glucose levels. Group 1: low glucose group (LLG), glucose < 168 mg/dL; and Group 2: high glucose group (HGG), glucose > 168 mg/dL. Results In-hospital, long term mortality and in-hospital major adverse cardiac events were higher in the high admission blood glucose group (P < 0.001). Multivariate regression analysis showed: Killip > 1, post-thrombolysis in MI < 3 and admission blood glucose levels were independent predictors of in-hospital adverse cardiac events (P < 0.001). Conclusions Admission hyperglycemia in elderly patients presented with ST elevation myocardial infarction is an independent predictor of in-hospital major adverse cardiac events and is associated with in-hospital and long term mortality.  相似文献

The association between uric acid and cardiovascular disease is incompletely understood. In particular, the prognostic value of uric acid in patients with acute coronary syndromes who undergo percutaneous coronary intervention has not been studied. This study included 5,124 patients with acute coronary syndromes who underwent percutaneous coronary intervention: 1,629 with acute ST-segment elevation myocardial infarction, 1,332 with acute non-ST-segment elevation myocardial infarction, and 2,163 with unstable angina. The primary end point was 1-year mortality. Patients were divided into quartiles according to uric acid level as follows: quartile 1, 1.3 to <5.3 mg/dl; quartile 2, 5.3 to <6.3 mg/dl; quartile 3, 6.3 to <7.5 mg/dl; and quartile 4, 7.5 to 18.4 mg/dl. There were 450 deaths during follow-up: 80 deaths in quartile 1, 77deaths in quartile 2, 72 deaths in quartile 3, and 221 deaths in quartile 4 of uric acid (Kaplan-Meier estimates of 1-year mortality 6.4%, 6.2%, 5.6%, and 17.4%, respectively; unadjusted hazard ratio 3.05, 95% confidence interval 2.54 to 3.67, p <0.001 for fourth vs first quartile of uric acid). After adjustment for traditional cardiovascular risk factors, renal function, and inflammatory status, the association between uric acid and mortality remained significant, with a 12% increase in the adjusted risk for 1-year mortality for every 1 mg/dl increase in the uric acid level. Uric acid improved the discriminatory power of the predictive model regarding 1-year mortality (absolute integrated discrimination improvement 0.008, p = 0.005). In conclusion, elevated levels of uric acid are an independent predictor of 1-year mortality across the whole spectrum of patients with acute coronary syndromes treated with percutaneous coronary intervention.  相似文献

The aim of our study was to examine the role of a new, simple protocol of intracoronary adenosine administration performed during primary angioplasty on the immediate angiographic results and clinical course. A prospective, single-center, randomized, placebo-controlled trial of 70 consecutive patients (64 ± 14 years, 54 men) with acute myocardial infarction with ST-segment elevation undergoing primary percutaneous coronary intervention (PCI) was conducted. Patients were randomized to 2 groups. Group 1 (n = 35) received intracoronary adenosine (1 to 2 mg) with a hand injection through the guiding catheter 2 times: immediately after crossing the lesion of the infarct-related artery with guidewire and then after the first balloon inflation. Group 2 (n = 35) received placebo. The baseline clinical and angiographic characteristics of the 2 groups were similar. Percutaneous coronary intervention resulted in Thrombolysis In Myocardial Infarction grade 3 flow after PCI in 32 patients (91.4%) in the adenosine group and 27 patients (77.1%) in the placebo group (p = 0.059). Myocardial blush grade 3 was observed at the end of PCI in 23 patients (65.7%) in the adenosine group and 13 (37.1%) in the placebo group (p < 0.05). Resolution of ST-segment elevation (> 50%) was more frequently observed in the adenosine than in the placebo group: 27 (77%) versus 15 (43%), respectively (p < 0.01). In conclusion, intracoronary adenosine administration improved the angiographic and electrocardiographic results in patients with acute myocardial infarction with ST-segment elevation undergoing PCI. Adenosine administration seemed to be associated with a more favorable clinical course.  相似文献

The prognostic value of the newly defined impaired fasting glucose (IFG) range (100 to 109 mg/dl) for the outcomes of patients undergoing percutaneous coronary interventions is unknown. We assessed the composite of death or myocardial infarction at 1 year of follow-up in 189 patients with IFG and 801 patients with a normal fasting glucose (<100 mg/dl), all with stable angina. The 1-year cumulative rate of death or myocardial infarction was 10.3% in the IFG group and 4.4% in the normal fasting glucose group (p = 0.002). In the multivariate model, IFG was an independent predictor of the occurrence of death or myocardial infarction (adjusted hazard ratio 2.30, 95% confidence interval 1.29 to 4.08, p = 0.005). An IFG of 100 to 109 mg/dl in patients with stable angina who undergo percutaneous coronary intervention may identify a patient subset with an increased risk of death or myocardial infarction.  相似文献

Compared to occlusions of other major coronary arteries, patients presenting with acute left circumflex (LCx) occlusion usually have ST-segment elevation on the electrocardiogram <50% of the time, potentially delaying treatment and resulting in worse outcomes. In contemporary practice, little is known about the clinical outcomes of patients with LCx territory occlusion without ST-segment elevation myocardial infarction (STEMI). We identified patients with myocardial infarction from April 2004 to June 2009 in the CathPCI Registry treated with percutaneous coronary intervention for culprit LCx territory occlusion, excluding those with previous coronary artery bypass grafting. Logistic generalized estimating equation modeling was used to compare the outcomes, including in-hospital mortality between patients with STEMI and non-STEMI (NSTEMI) adjusting for differences in the baseline characteristics. Of the 27,711 patients with myocardial infarction and acute LCx territory occlusion, 18,548 (67%) presented with STEMI and 9,163 (33%) with NSTEMI. With the exception of a greater proportion of cardiac risk factors and cardiac history in the NSTEMI group, the demographic and baseline characteristics were clinically similar between the 2 groups, despite the statistical significance resulting from the large population. The patients with STEMI were more likely to have a proximal LCx culprit lesion (63% vs 27%, p <0.0001) and had greater risk-adjusted in-hospital mortality (odds ratio 1.36, 95% confidence interval 1.12 to 1.65, p = 0.002) compared to patients with NSTEMI. In conclusion, acute LCx territory occlusion often presents as NSTEMI, but patients with NSTEMI and occlusion have a lower mortality risk than those with STEMI, possibly because of factors such as the amount of myocardium involved, the lesion location along the vessel, and/or a dual blood supply.  相似文献

PURPOSE: To determine the impact of cigarette smoking on the presentation, treatment, and in-hospital outcomes of patients admitted with the full spectrum of acute coronary syndromes. METHODS: GRACE is a multinational observational registry involving 94 hospitals in 14 countries. This analysis is based on 19,325 patients aged at least 18 years admitted for acute coronary syndromes as a presumptive diagnosis with at least one of the following: electrocardiographic changes consistent with acute coronary syndromes, serial increases in serum biochemical markers of cardiac necrosis, and/or documentation of coronary artery disease. The main outcomes measured were mode of presentation, treatment and in-hospital death in the ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina groups to assess the impact of smoking status. RESULTS: Smokers were more frequently diagnosed with ST-segment elevation myocardial infarction (46.0%) than former smokers (27.4%) and non-smokers (30.2%) (P<0.001). Smokers were mostly men, were younger and more aggressively treated than former smokers and non-smokers across the three acute coronary syndrome groups. Unadjusted in-hospital mortality rates were lower in smokers compared with former smokers and non-smokers in the study population (3.3%, 4.5%, and 6.9%, respectively, P<0.001), and in the ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction groups. However, by multivariate logistic analysis, the adjusted in-hospital mortality rate was similar regardless of smoking status. CONCLUSIONS: There is no survival advantage related to current or prior cigarette smoking in patients admitted with acute coronary syndromes, regardless of presentation. In this large multinational registry, the smokers' paradox does not exist.  相似文献

The impact of left ventricular (LV) dyssynchrony on the long-term outcomes of patients with acute myocardial infarction (AMI) remains unknown. The purpose of the present study was to evaluate the prevalence of LV dyssynchrony after AMI and the potential relation with adverse events. A total of 976 consecutive patients admitted with AMI treated with primary percutaneous coronary intervention were evaluated. Two-dimensional echocardiography was performed <48 hours after admission. LV dyssynchrony was assessed with speckle-tracking imaging and calculated as the time difference between the earliest and latest activated segments. Patients were followed up for the occurrence of all-cause mortality (the primary end point) or the composite secondary end point (heart failure hospitalization and all-cause mortality). Within 48 hours of admission for the index infarction, mean LV dyssynchrony was 61 ± 79 ms, and 14% of the patients demonstrated a ≥130-ms time difference, defined as significant LV dyssynchrony. During a mean follow-up period of 40 ± 17 months, 82 patients (8%) reached the primary end point. In addition, 36 patients (4%) were hospitalized for heart failure. The presence of LV dyssynchrony was associated with an increased risk for all-cause mortality and hospitalization for heart failure during long-term follow-up (adjusted hazard ratio 1.06, 95% confidence interval 1.05 to 1.08, p <0.001, per 10-ms increase). Moreover, LV dyssynchrony provided incremental value over known clinical and echocardiographic risk factors for the prediction of adverse outcomes. In conclusion, LV dyssynchrony is a strong predictor of long-term mortality and hospitalization for heart failure in a population of patients admitted with ST-segment elevation AMI treated with primary percutaneous coronary intervention.  相似文献

Inflammation plays a critical role in acute myocardial infarction. One inflammatory marker is myeloperoxidase (MPO). Its role as a predictor of in-hospital death in patients with ST-segment elevation myocardial infarction (STEMI) presenting with cardiogenic shock (CS) is unclear. Therefore, the aim of this study was to investigate the role of MPO as a predictor of in-hospital death in patients with STEMIs presenting with CS and treated with primary percutaneous coronary intervention. In 38 consecutive patients with CS complicating STEMIs who were treated with primary percutaneous coronary intervention, serum MPO levels were measured at coronary care unit admission using a commercially available enzyme-linked immunosorbent assay. The primary study end point was in-hospital cardiac death. Among the 38 patients included in the study, 20 died during their coronary care unit stays, whereas 18 survived. Compared with patients who survived, patients who died showed, at coronary care unit admission, higher serum MPO levels (81 +/- 28 vs 56 +/- 23 ng/ml, p <0.006). After controlling for different baseline clinical, laboratory, and angiographic variables, baseline serum MPO level was an independent predictor of in-hospital mortality on multivariate analysis (odds ratio 3.9, 95% confidence interval 1.8 to 7.5, p <0.001). In conclusion, admission MPO concentration is an independent predictor of in-hospital mortality in patients with STEMIs presenting with CS.  相似文献

After the introduction of drug-eluting stents (DESs), percutaneous coronary intervention with DESs has challenged coronary artery bypass grafting as the gold standard for the treatment of 3-vessel coronary artery disease. The purpose of this study was to compare the long-term clinical results between percutaneous coronary intervention with DESs and off-pump coronary artery bypass grafting (OPCAB) in 3-vessel coronary artery disease. Two hundred ninety propensity-score matched patients with 3-vessel coronary artery disease treated by DESs or OPCAB were included. Mean follow-up duration was 58.8 ± 11.5 months (2 to 73) and follow-up rate was 97.9%. Five-year survival rates were 94.8 ± 2.1% in the DES group and 96.5 ± 1.5% in the OPCAB group (p = 0.658). Five-year rates of freedom from major adverse cardiac and cerebrovascular event were 71.6 ± 4.1% in the DES group and 89.6 ± 2.5% in the OPCAB group (p < 0.001). Freedom from nonfatal myocardial infarction and target vessel revascularization rates were the determining factors between the 2 groups (p = 0.018 and p < 0.001, respectively). The OPCAB group showed better clinical outcomes compared to the DES group in 3-vessel coronary artery disease after 5-year follow-up. Freedom from major adverse cardiac and cerebrovascular event rate was significantly higher in the OPCAB group mainly because of the lower incidence of target vessel revascularization and nonfatal myocardial infarction. Longer follow-up with randomization will clarify our present conclusions.  相似文献

We assessed the clinical features of patients with myocardial rupture within 48 to 72 hours, defined as early myocardial rupture, after percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction (STEMI). Six patients (4 men, 66 ± 13 years) with early myocardial rupture were identified from 1252 consecutive patients undergoing PCI for STEMI. We evaluated the degree of microvascular reperfusion using thrombolysis in myocardial infarction (TIMI) myocardial perfusion (TMP) grade and a resolution of sum of ST-segment elevation in a 12-lead electrocardiogram (ECG). Time from PCI to myocardial rupture was 11 ± 7 hours. All patients showed TMP grade 0 or 1 and an increase in sum of ST-segment elevation after PCI (1.9 ± 0.5 vs 2.5 ± 0.7 mV; P = .032), suggesting severely failed reperfusion at the level of microcirculation as the common feature to develop early myocardial rupture after PCI for STEMI.  相似文献

Methods A total of 6005 patients who received coronary revascularization in our institution between July 2003 and September 2005 were enrolled. The patients were followed up in clinic or by telephone after discharge between September 2006 and November 2006. The clinical and prognosis data of all-cause mortality, neo-myocardial infarction, nonfatal stroke, and rerevascularization of ST-segment elevation myocardial infarction ( STEMI ) , non ST-segment elevation myocardial infarction ( NSTEMI) and major adverse cardiovascular and cerebrovascular events ( MACCE) were analyzed. Results Among 4865 acute coronary syndrome patients, 955 cases were STEMI; 263 cases were NSTEMI; and 3647 cases were unstable angina ( UA) pectoris. There were no significant difference for in-hospital mortality and late mortality ( 18 month survival 96% , 98% and 98% ) between patients with STEMI, NSTEMI and UA. Patients with UA had lower MACCE rate (18 month non-MACCE survival of STEMI, NSTEMI and UA group were 86% , 86% , and 89% respectively). Conclusions Despite different clinical characteristics, patients with STEMI, NSTEMI and UA undergoing revascularization had similar short-term and long-term mortality. Patients with UA had lower MACCE rate.  相似文献
