Elevated serum creatinine is associated with 1-year mortality after acute myocardial infarction

Background Cardiovascular mortality is high in individuals with end-stage renal disease. However, less is known about the prognostic importance of moderate renal insufficiency in patients with acute myocardial infarction. Methods We studied all patients with acute myocardial infarction admitted through the emergency department to an urban, academic hospital over 1 year. Patients were classified as having elevated (>133 μmol/L [1.5 mg/dL]) or normal (≤133 μmol/L) serum creatinine at presentation. Results Of 483 patients, 22% had elevated creatinine and 78% had normal creatinine. By 1 year, 46% of patients with elevated creatinine and 15% of patients with normal creatinine had died (P < .001). The unadjusted hazard ratio for 1-year mortality was increased in patients with elevated creatinine compared with those with normal creatinine (hazard ratio 3.85, 95% CI 2.61-5.67). After adjustment for baseline characteristics and treatment, the multivariable-adjusted hazard ratio for 1-year mortality remained increased in patients with elevated creatinine compared with those with normal creatinine (hazard ratio 2.40, 95% CI 1.55-3.72). There was an important modification of the prognostic value of creatinine by the presence of congestive heart failure at presentation (P value for interaction = .04). The adjusted hazard ratio for 1-year death associated with elevated creatinine compared with normal creatinine was 3.89 (95% CI 1.87-8.07) in patients without congestive heart failure and 1.92 (95% CI 1.10-3.36) in patients with congestive heart failure. Conclusions Elevated serum creatinine at presentation is associated with 1-year mortality after acute myocardial infarction. Further study is needed to optimize treatment after myocardial infarction in this high-risk group. (Am Heart J 2002;144:1003-1011.)     

One-year survival among patients with acute myocardial infarction complicated by cardiogenic shock, and its relation to early revascularization: results from the GUSTO-I trial

BACKGROUND: Although 30-day survival is increased in patients with acute myocardial infarction complicated by cardiogenic shock who undergo coronary revascularization, the longer-term outcome in such patients and the duration of benefit from revascularization are unknown. METHODS AND RESULTS: We analyzed 30-day survivors of acute myocardial infarction in the Global Utilization of Streptokinase and Tissue-Plasminogen Activator for Occluded Coronary Arteries (GUSTO-I) trial and identified 36 333 who had not had cardiogenic shock (systolic blood pressure <90 mm Hg for >/=1 hour, group 1) and 1321 patients who had shock (group 2). Group 2 patients were older and sicker. At 1 year, 97.4% of group 1 patients were alive versus 88.0% of group 2 (P=0.0001). Among group 2 patients, 578 (44%) had undergone revascularization within 30 days (group 2A) and 728 (56%) had not (group 2B). Revascularization was not required by protocol but was selected by the attending physicians. At 1 year, 91.7% of group 2A patients were alive versus 85.3% of group 2B (P=0.0003). With the use of multivariable logistic regression analysis to adjust for differences in baseline characteristics of shock patients alive at 30 days, revascularization within 30 days was independently associated with reduced 1-year mortality (odds ratio 0.6, [95% confidence interval 0.4, 0.9], P=0.007). CONCLUSIONS: Most patients (88%) with acute myocardial infarction complicated by cardiogenic shock who are alive at 30 days survived at least 1 year. Shock patients who underwent revascularization within 30 days had improved survival at 1 year compared with shock patients who did not receive revascularization, even after adjustment for differences in baseline characteristics between the 2 groups.     

老年危重急性心肌梗死患者机械通气治疗临床转归的多因素分析

目的观察老年危重急性心肌梗死患者行机械通气治疗的疗效,探讨与死亡相关的预测因素。方法回顾分析使用气管插管机械通气治疗的老年危重急性心肌梗死患者41例,观察机械通气治疗的疗效并对影响患者预后的相关因素进行分析。结果41例患者康复出院14例,院内死亡27例(66%)。多因素分析表明,入院时血肌酐升高(肌酐>133μmol/L),左心室射血分数严重减低(左心室射血分数<35%),上呼吸机时血压偏低[收缩压<100mm Hg(1 mm Hg=0.133 kPa)]是增加死亡风险的独立预测因素。结论老年危重急性心肌梗死患者行机械通气治疗死亡率仍然很高;肾功能、心功能是死亡风险的独立预测因素。     

血清肌酐水平对ST段抬高性心肌梗死急诊PCI治疗患者预后的影响

目的探讨血清肌酐水平对ST段抬高性心肌梗死（STEMI）急诊经皮冠状动脉介入治疗（PCI）患者预后的影响。方法接受急诊PCI治疗的495例STEMI患者,根据入院即刻肌酐水平分为肌酐正常组409例和肌酐升高组86例,随诊1 a,比较两组患者院内和1 a时的病死率及主要不良心脏事件（MACE,包括死亡、心肌梗死、需要血运重建的心绞痛）的发生情况。结果入院肌酐升高组患者与正常组比较,年龄大,高血压患者发病率及既往心肌梗死发病率高,心功能差,院内病死率和随访1 a时病死率、MACE发生率均较高,差异有统计学意义（P均〈0.05）。多变量回归分析显示,入院肌酐水平与STEMI接受急诊PCI治疗患者1 a病死率密切相关（RR=1.41,95%CI：1.24-2.69,P=0.02）。结论STEMI接受急诊PCI治疗患者入院时的肌酐水平对预测患者预后有重要意义。     

急性心肌梗死患者急诊经皮冠状动脉介入治疗后对比剂肾病的研究

目的:了解对比剂对急性心肌梗死行急诊经皮冠状动脉(冠脉)介入治疗(PCI)患者肾功能的影响,探讨对比剂肾病(CIN)的相关因素及其对患者预后的影响。方法:入选118例行急诊PCI的急性ST段抬高心肌梗死患者,测定其术前和术后48、72h的血清肌酐,记录其治疗经过和住院期间发生的不良事件。结果:118例患者中发生CIN(CIN组)28例(23.7%)。CIN组基线肾小球滤过率(GFR)和左心室射血分数(LVEF)低于非CIN组(均P<0.05),而肌酸激酶(CK)峰值高于非CIN组(P<0.05)。CIN组住院时间比非CIN组长(P<0.01),住院期间不良事件发生率更多。Logistic回归分析发现,LVEF3000U/L与CIN的发生有关。结论:CIN是急诊PCI患者的常见并发症,可能增加住院期间不良事件的发生率,临床工作中要积极预防CIN的发生。     

An invasive strategy is associated with decreased mortality in patients with unstable angina and non-ST-elevation myocardial infarction: GUSTO IIb trial

There has been much debate concerning an invasive versus a conservative strategy for patients with acute coronary syndromes. The purpose of this study was to determine whether early in-hospital catheterization reduced mortality in patients with unstable angina and non-ST-elevation myocardial infarction.We performed a retrospective analysis of data collected in the Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO) IIb trial, which compared hirudin and heparin in patients with acute coronary syndromes. We identified 8011 patients with non-ST-segment elevation myocardial infarction and unstable angina who were enrolled in the trial. The primary endpoints were all-cause mortality at 30 days and 1 year. Data were analyzed with multivariate hazards models and propensity scores.After accounting for inception time bias, there were 7897 patients identified, of whom 4536 patients (57%) underwent invasive therapy and 3361 (43%) underwent conservative therapy. Adjusting for propensity scores, the adjusted 30-day mortality for the invasive group was 2.5% compared with 2.7% in the conservative group (P = 0.92); at 1 year, the invasive group had a 6.2% mortality, versus 8.6% in the conservative group (P = 0.005). In a multivariate analysis that adjusted for other clinical factors, an invasive strategy was associated with lower 1-year mortality (hazard ratio = 0.46; 95% confidence interval: 0.10 to 0.84).In patients presenting with acute coronary syndromes, an invasive strategy is associated with improved survival at 1 year even after adjusting for baseline differences.     

Association between increased levels of reverse triiodothyronine and mortality after acute myocardial infarction.

PURPOSE: The thyroid hormone system may be downregulated temporarily in patients who are severely ill. This "euthyroid sick syndrome" may be an adaptive response to conserve energy. However, thyroid hormone also has beneficial effects on the cardiovascular system, such as improving cardiac function, reducing systemic vascular resistance, and lowering serum cholesterol levels. We investigated whether thyroid hormone levels obtained at the time of myocardial infarction are associated with subsequent mortality. PATIENTS AND METHODS: Serum levels of thyroid hormones (triiodothyronine [T3], reverse T3, free thyroxine [T4], and thyroid-stimulating hormone) were measured in 331 consecutive patients with acute myocardial infarction (mean age [+/- SD], 68 +/- 12 years), from samples obtained at the time of admission. RESULTS: Fifty-three patients (16%) died within 1 year. Ten percent (16 of 165) of patients with reverse T3 levels (an inactive metabolite) >0.41 nmol/L (the median value) died within the first week after myocardial infarction, compared with none of the 166 patients with lower levels (P <0.0004). After 1 year, the corresponding figures were 24% (40 of 165) versus 7.8% (13 of 166; P <0.0001). Reverse T3 levels >0.41 nmol/L were associated with an increased risk of 1-year mortality (hazard ratio = 3.0; 95% confidence interval: 1.4 to 6.3; P = 0.005), independent of age, previous myocardial infarction, prior angina, heart failure, serum creatinine level, and peak serum creatine kinase-MB fraction levels. CONCLUSION: Determination of reverse T3 levels may be a valuable and simple aid to improve identification of patients with myocardial infarction who are at high risk of subsequent mortality.     

Thrombolytic treatment and proteinuria.

OBJECTIVES--To determine whether patients with acute myocardial infarction undergoing thrombolysis with streptokinase develop changes in renal function. DESIGN--Prospective assessment of renal function in 60 consecutive patients admitted with acute myocardial infarction. SETTING--Tertiary referral centre and city general hospital. PATIENTS--60 consecutive patients with acute myocardial infarction. Thirty eight were given streptokinase and 17 tissue plasminogen activator (alteplase) and five no thrombolytic agent (non-streptokinase group). MAIN OUTCOME MEASURES--Proteinuria and creatinine clearance on admission (day 1) and on days 3 and 6; serum urea and creatinine concentrations on days 1 and 7; streptokinase IgG on days 1, 2, and 7. RESULTS--Significant proteinuria (> 0.15 g/24 h) was found in 31 (82%) of the 38 patients in the streptokinase group (mean 0.47 g/24 h (95% confidence interval 0.35 to 0.6 g/24 h)) in the 24 hours after admission compared with six (27%) out of 22 in the non-streptokinase group (mean 0.17 g/24 h (0.12 to 0.2 g/24 h); P = 0.008). In the streptokinase group this decreased to the normal range by day 3 (mean 0.15 g/24 h (0.1 to 0.22 g/24 h); P = 0.0001 v baseline). Electrophoresis of urine showed the proteinuria to be glomerular in origin. Creatinine clearance and serum creatinine and urea concentrations were similar in both groups. In the streptokinase group detectable streptokinase IgG titres were found in 28 out of 32 (87%) patients. The median titre on admission was 16 (range 0-110); it fell to 3 (range 0-80; P = 0.001) by day 2 and increased to 61 (range 0-7700; P = 0.0002 v baseline) by day 7. CONCLUSIONS--Streptokinase was associated with significant early onset proteinuria of glomerular origin. This started to resolve by day 3 and resulted in no deterioration in overall renal function. The temporal relation to the initial fall in antibody titre suggests that it could be the result of immune complex deposition in the glomeruli.     

Cardiac troponin T in acute coronary syndrome with renal insufficiency

Cardiac troponin levels are frequently elevated in patients with chronic renal failure, hence diagnosis of myocardial necrosis is difficult. The prevalence of elevated serum troponin T was determined and its diagnostic value in acute coronary syndrome was assessed in patients with chronic renal insufficiency. A retrospective cross-sectional analysis was performed in 227 patients with chronic renal insufficiency and a diagnosis of unstable angina, non-ST or ST-segment elevation myocardial infarction. All patients had baseline serum troponin T levels measured at previous visits; the baseline troponin T level was raised in 53.3%. Cardiac troponin T levels did not correlate with creatinine levels, and were not affected by dialysis. Mortality after an acute coronary event was high (46.3%). Because of the elevated baseline cardiac troponin T levels, detection of acute coronary syndrome in patients with chronic renal failure requires evaluation of serial cardiac enzyme measurements and serial 12-lead electrocardiograms. Early and definitive cardiac interventions may contribute towards decreasing the mortality rate in this group of patients.     

缺血性卒中对急性心肌梗死患者入院后死亡的影响

目的探讨缺血性卒中病史对急性心肌梗死患者入院后死亡的影响作用。方法回顾性分析2004年2月—2009年8月以心电图初发急性sT段抬高型心肌梗死入院的患者共918例,以入院期间是否死亡将患者分为存活组（811例）及死亡组（107例）。比较两组患者的一般资料、发病特点和治疗情况,采用多元Logistic回归分析探讨缺血性卒中病史是否为急性心肌梗死患者近期死亡的独立危险因素。结果①死亡组缺血性卒中患者比例（22例,20．6％）高于存活组（101例,12．5％）,差异有统计学意义（,=5．354,P〈0．05）。②存活组和死亡组患者的年龄、糖尿病史及高血压病史比例、血压、空腹血糖、白细胞计数、血肌酐、严重心律失常并发症比例、左心室射血分数、治疗方式比较后,差异均具有统计学意义,P〈0．05。③多元Logistic回归分析表明,缺血性卒中病史并不是急性心肌梗死患者死亡预后的独立危险因素（P〉0．05,OR=1．027,95％CI．O．263～4．004）。结论合并缺血性卒中的患者在急性心肌梗死入院死亡的人群中具有更集中的现象,但是经过校正后,其对急性心肌梗死入院死亡预后的独立影响作用尚不明确。
