目的:前瞻性评价替罗非班对急性ST段抬高型心肌梗死(STEMI)患者直接经皮冠状动脉(冠脉)介入治疗(PCI)后左室功能及临床预后的作用。方法:将145例接受直接PCI治疗的急性STEMI患者,随机分为替罗非班组(73例)和对照组(72例)。比较2组基础临床情况、冠脉造影和PCI结果、住院期及术后第90天左室舒张末期容积(EDV)、收缩末期容积(ESV)、左室射血分数(LVEF)及主要心脏不良事件(MACE,包括死亡、再梗死、再次靶血管重建)发生率。结果:2组基础临床情况、冠脉造影及PCI结果差异均无统计学意义(P>0.05)。替罗非班组住院期的EDV、ESV、LVEF与对照组比较,分别为P>0.05[(134±28)ml∶(146±46)ml]、P<0.05[(67±17)ml∶(81±36)ml]、P<0.05[(49±7)∶(45±9)%];术后第90天的EDV、ESV、LVEF与对照组比较,分别为P>0.05[(147±31)∶(158±62)ml]、P<0.05[(61±20)∶(79±41)ml]、P<0.01[(58±8)∶(51±9)%]。替罗非班组住院期间及术后第90天MACE发生率均显著低于对照组(均P<0.05),分别为5.5%∶15.3%及6.8%∶18.1%。多因素Logistic回归分析表明,替罗非班治疗(OR=0.76,P<0.05)、年龄<65岁(OR=0.83,P<0.01)、住院期LVEF≥0.5(OR=0.49,P<0.05)是降低术后MACE发生率的主要决定因素。结论:急性STEMI患者直接PCI联合替罗非班治疗,能显著改善住院期和术后左室收缩功能及临床预后。 相似文献

目的:前瞻性评价心肌梗死急诊直接经皮冠状动脉介入治疗(PCI)术中联合应用血小板Ⅱh/Ⅲa受体拮抗剂替罗非班对术后ST段回落及临床预后的影响。方法:141例接受急诊PCI治疗的初发急性ST段抬高型心肌梗死患者,随机分成替罗非班组(71例)和对照组(70例)。比较两组基础临床情况、介入治疗结果、急诊PCI术后1小时ST段抬高总和(∑ST)回落、术后90天左心室射血分数及主要心脏不良事件[再梗死、心力衰竭、再次血运重建(PCI/冠状动脉旁路移植术)、死亡]、胸痛复发的发生率。结果:两组基础临床情况、急诊PCI术前∑ST及梗死相关血管开通率均无显著性差异。替罗非班组与对照组相比, 2ST回落明显增加[(6.39±3.43)mm比(4.49±2.43)mm,P<0.01],术后90天主要心脏不良事件(死亡、再梗死、心力衰竭、再次血运重建)发生率(9.9%比25.7%,P<0.05)和胸痛复发率(7%比20%,P<0.05)均显著降低,左心室射血分数(0.59±0.06比0.52±0.06,P<0.01)显著增高。其中替罗非班组心力衰竭发生率(8.50%比22.9%,P<0.05)显著降低,但再梗死、再次血运重建及死亡发生率无显著性差异(P>0.05)。∑ST回落和替罗非班治疗(r=0.361,P< 0.01)及术后90天左心室射血分数(r=0.613,P<0.01)显著相关。多因素分析显示,替罗非班治疗是∑ST回落的唯一独立决定因素(P<0.01)。替罗非班组术后出血并发症发生率高于对照组,但无统计学意义(P>0.05)。结论:心肌梗死急诊直接PCI联合应用替罗非班安全有效,并显著加速ST段回落,显著改善术后90天临床预后和左心室功能。 相似文献

Background/PurposeDirect Stenting (DS) could be associated with reduced distal embolization and improved reperfusion in patients with ST-segment elevation myocardial infarction (STEMI). However, the impact of DS on long-term outcomes remains unclear, therefore we evaluated the impact of DS on very long-term clinical outcome in STEMI.Methods/MaterialsBetween April 2002 and December 2004, patients presenting with STEMI undergoing percutaneous coronary intervention were investigated. The study population was divided into two groups: DS and conventional stenting (CS) and stratified according to initial TIMI flow. Major adverse cardiac events (MACE) were assessed at 10 years and all-cause mortality at 15 years. Cox proportional hazards models were used. When the proportional hazards assumption was not satisfied, landmark analysis at mid-term (2 years) was performed.ResultsA total of 812 consecutive patients were evaluated, 6 patients were excluded due to inadequate angiographic images, 450 (55.8%) underwent DS and 356 (44.2%) CS.At 15 years follow-up, DS was associated with a reduction in all-cause mortality (DS 35.0% vs. CS 45.3%, aHR 0.74, 95% CI 0.58–0.93, p = 0.010). The landmark analysis at 2 years identifies reduced 2-year MACE in DS compared with CS (6.8% vs.14%, aHR 0.67, 95% CI 0.49–0.93, p = 0.015) and beyond 2 years no significant differences were found between the groups (27.4% vs. 29.3%, aHR 1.00, 95% CI 0.74–1.36, p = 0.999). In patients with baseline TIMI 0–1, DS was associated with lower 10-year MACE and 15-year mortality compared with CS (aHR0.71, 95%CI 0.55–0.92, p = 0.010 and aHR0.65, 95%CI 0.50–0.84, p = 0.001, respectively).ConclusionsDS was associated with reduced 15-year all-cause mortality and reduced mid-term MACE rate in patients with STEMI. Clinical events reduction associated with DS was particularly relevant in patients with initial TIMI flow 0–1. 相似文献

Background
There are few published studies of ST-segment elevation myocardial infarction (STEMI) in younger individuals. The differences between these “younger” and “older” individuals may not be fully appreciated by clinicians. The aim of this study was to determine the reasons for the earlier presentation and help to identify strategies for prevention of recurrent myocardial infarction (MI) in younger patients.Methods
The study population was a cohort of 2,419 consecutive STEMI patients who were treated with primary percutaneous coronary intervention. The median follow-up time of this retrospective study was 2.2 years.Results
The all-cause mortality rates in patients ≤45 years of age at 30 days, 1 and 2 years were 1.7%, 2.0% and 2.2%, respectively. These rates were lower compared with their older matched counterparts whose all-cause mortality rates were 3.3%, 4.2% and 5.5%, respectively (P = 0.010). The incidence of recurrent MI was 4.0% for all age groups combined, 5.4% for younger patients and 3.8% for older patients. The number of stents showed association with recurrent MI in older patients with a first infarction, whereas only composition factor 1 with significantly higher non–high-density lipoprotein and low-density lipoprotein values was significantly associated with recurrent MI in the younger patients.Conclusions
STEMI patients ≤45 years of age more often had lower rates of all-cause mortality, but the risk of recurrent MI was similar to that of older patients. Regardless of triglyceride level, neither non–high-density lipoprotein nor low-density lipoprotein were independent predictors for recurrent MI during the long-term follow-up in younger patients. 相似文献13.

ObjectivesThis study sought to assess the association between postprocedural anticoagulation (PPAC) use and several clinical outcomes.BackgroundPPAC after primary percutaneous coronary intervention (pPCI) in patients with ST-segment elevation myocardial infarction (STEMI) may prevent recurrent ischemic events but may increase the risk of bleeding. No consensus has been reached on PPAC use.MethodsUsing data from the Improving Care for Cardiovascular Disease in China–Acute Coronary Syndrome registry, conducted between 2014 and 2019, we stratified all STEMI patients who underwent pPCI according to the use of PPAC or not. Inverse probability of treatment weighting and a Cox proportional hazards model with hospital as random effect were used to analyze differences in in-hospital clinical outcomes: the primary efficacy endpoint was mortality and the primary safety endpoint was major bleeding.ResultsOf 34,826 evaluable patients, 26,272 (75.4%) were treated with PPAC and were on average younger, more stable at admission with lower bleeding risk score, more likely to have comorbidities and multivessel disease, and more often treated within 12 hours of symptom onset than those without PPAC. After inverse probability of treatment weighting adjustment for baseline differences, PPAC was associated with significantly reduced risk of in-hospital mortality (0.9% vs 1.8%; HR: 0.62; 95% CI: 0.43-0.89; P < 0.001) and a nonsignificant difference in risk of in-hospital major bleeding (2.5% vs 2.2%; HR: 1.05; 95% CI: 0.83-1.32; P = 0.14).ConclusionsPPAC in STEMI patients after pPCI was associated with reduced mortality without increasing major bleeding complications. Dedicated randomized trials with contemporary STEMI management are needed to confirm these findings. 相似文献
