Effects of upstream tirofiban versus downstream tirofiban on myocardial damage and 180-day clinical outcomes in high-risk acute coronary syndromes patients undergoing percutaneous coronary interventions

Background For patients with moderate to high-risk acute coronary syndromes （ACS） who undergo early, invasive treatment strategies, current guidelines recommend the usage of glycoprotein （GP） lib/Ilia inhibitors as an upstream treatment for a coronary care unit or as an downstream provisional treatment for selected patients who are undergoing percutaneous coronary intervention （PCI）. The relative advantage of either strategy is unknown. The purpose of this study was to evaluate the effects of upstream tirofiban versus the effects of downstream tirofiban on myocardial damage and 180-day major adverse cardiovascular events （MACE） after PCI in high-risk non-ST-segment elevation ACS （NSTE-ACS） undergoing PCI. Methods From July 2006 to July 2007, 160 high-risk NSTE-ACS undergoing PCI were randomized to receive upstream （within 4-6 hours before coronary angiography） tirofiban or downstream （the guidewire crossing the lesion） tirofiban, to evaluate the extent of myocardial damage after PCI by quantitatively and qualitatively analyzing the value of cardiac troponin I （cTnl） as well as MB isoenzyme of creatine kinase （CK-MB） before and after PCI. The incidences of 24-hour, 3-day, 7-day, 30-day and 180-day MACE after PCI were followed up and the rates of bleeding complications and thrombocytopenia during tirofiban administration were recorded. Results The peak release and cumulative release of cTnl levels within 48 hours after PCI were significantly lower with upstream tirofiban than downstream tirofiban （0.45 vs 0.63 and 0.32 vs 0.43, respectively; P 〈0.05）. Post-procedural cTnl elevation within 48 hours was significantly less frequent among patients who received the upstream tirofiban than those who received the downstream tirofiban （66.3% vs 87.5%, P 〈0.05）. The peak and cumulative release of CK-MB levels as well as post-procedural CK-MB elevation within 48 hours after PCI were not significantly different between the two groups （16 vs 14,5 vs 3 and 26.3% vs 36.3%, respectively; P 〉0.05）. The incidences of 24-hour, 3-day, and 7-day MACE after PCI were the same between the two groups （0 vs 0, 0 vs 0 and 1.25% vs 1.25%, respectively）. Although the incidences of 30-day and 180-day MACE after PCI were not statisticially different between the two groups, the incidences were consistently lower with upstream tirofiban （3.75% vs 6.25% and 12.99% vs 16.67%; P 〉0.05）. Aging （OR=1.164, P 〈0.001）, hypertension （OR=4.165, P=0.037） and type 2 diabetes （OR=13.628, P 〈0.001） were independent risk factors of MACE. The timing of administrating the tirofiban （OR=2.416, P=-0.153） plays an extensive role in the incidence of MACE. The incidences of major and minor bleeding complications as well as mild thrombocytopenia during the administration of tirofiban were similar between the two groups （2.50% vs 1.25%, 1.25% vs 1.25% and 1.25% vs 1.25%, respectively; P 〉0.05）. Conclusions Based on the pretreatment with aspirin and clopidogrel, upstream tirofiban was associated with attenuated minor myocardial damage and the tendency of reducing incidences of 180-day MACE after PCI among high-risk NSTE-ACS patients undergoing PCI. Aging, hypertension and type 2 diabetes were independent risk factors of MACE in high-risk NSTE-ACS patients undergoing PCI associated with tirofiban.     

Absence of gender disparity in short-term clinical outcomes in patients with acute ST-segment elevation myocardial infarction undergoing sirolimus-eluting stent based primary coronary intervention: a report from Shanghai Acute Coronary Event (SACE) Registry

Background Randomized, controlled trials have demonstrated the superiority of sirolimus-eluting stent （SES） implantation during primary percutaneous coronary intervention （PCI）, as opposed to bare-metal stents, in patients with ST-elevation myocardial infarction （STEMI）. This study aimed to test the hypothesis that clinical benefits of SES treatment were independent of gender in this setting.Methods A total of 2042 patients with STEMI undergoing SES-based primary PCI were prospectively enrolled into Shanghai Acute Coronary Event （SACE） registry （1574 men and 468 women）. Baseline demographics, angiographic and PCI features, and in-hospital and 30-day major adverse cardiac events （MACE） were analyzed as a function of gender. Results Compared with men, women were older and more frequently had hypertension, diabetes, and hypercholesterolemia. Use of platelet glycoprotein IIb/IIIa receptor inhibitor （GPI, 65.5% vs. 62.2%, P=0.10） and procedural success rate （95.0% vs. 94.2%, P=0.52） were similar in both genders. In-hospital death and MACE occurred in 3.8% and 7.6%, and 4.5% and 8.1% in the male and female patients, respectively （all P 〉0.05）. At 30-day follow-up, survival （94.3% vs. 93.8%, P=0.66） and MACE-free survival （90.2% vs. 89.3%, P=0.52） did not significantly differ between men and women. After adjustment for differences in patient demographics, angiographic and proceduralfeatures, there were no significant difference in either in-hospital （OR=0.77, 95%C/ of 0.48 to 1.22, P=0.30） or 30-day mortality （OR=1.28, 95%C/ of 0.73 to 2.23, P=0.38） between women and men.Conclusion Despite more advanced age and clustering of risk factors in women, female patients with STEMI treated by SES-based primary PCI had similar in-hospital and short-term clinical outcomes as their male counterparts.     

Long-term outcome of patients of over 85 years old with acute coronary syndrome undergoing percutaneous coronary stenting: a comparison of bare metal stent and drug eluting stent

Background Patients aged over 85 years have been under-represented in percutaneous coronary intervention （PCI） trials despite an increase in referrals for PCI. The long-term safety and efficacy of percutaneous coronary stenting in patients aged over 85 years with acute coronary syndrome （ACS） remain unclear. Moreover it is unknown whether there are differences between bare metal stent （BMS） and drug eluting stent iDES） in this special population.
Methods A total of 80 patients with ACS aged over 85 years undergoing stenting （BMS group n=21 vs DES group n=59） were retrospectively studied. In-hospital, one year and overall clinical follow-up （12-36 months） of major adverse cardiac events （MACEs） including cardiac deaths, myocardial infarction, target lesion revascutarization （TLR） and target vessel revascularization （TVR） as well as stroke and other major bleeding were compared between the two groups.
Results In the entire cohort, the procedure success rate was 93.8% with TIMI-3 coronary flow post-PCI in 93.8% of the vessels and the procedure related complication was 17.5%. The incidence of in-hospital MACEs in BMS group was higher （14.3% vs 6.8%, P=0.30）. The 1-year incidence of MACEs in DES group was 7.0% while there was no MACE in the BMS group. Clinical follow-up for 12-36 months showed that the overall survival free from MACE was 82.9% and the incidence of MACE in the BMS group was lower （5.3% vs 21.1%, P=0.20）. Multivariate regression analysis showed that the creatinine level （OR：. 1.013; 95%CI： 1.006-1.020; P=0.004） and hypertension （OR; 3.201; 95%CI： 1.000-10.663; P=0.04） are two major factors affecting the long-term MACE.
Conclusions Percutaneous coronary stenting in patients aged over 85 years is safe and provides good short and tona-term efficacy. Patients with renal dvsfunction and hvoertension may have a relatively hiah incidence of MACE.

Gender differences in efficacy of primary percutaneous coronary intervention in patients with ST-elevation myocardial infarction

Background The clinical outcome of percutaneous coronary intervention （PCI） is poorer in women than that in men. This study aimed at comparing the impact of gender difference on the strategy of primary PCI in patients with acute ST-segment elevation myocardial infarction （STEMI）.
Methods Two hundred and fifty-nine patients with STEMI who underwent primary PCI within 12 hours of symptom onset were enrolled. The male group consisted of 143 men aged 〉55 years, and a female group included 116 women without age limitation. Procedural success was defined as residual stenosis 〈20% with thrombolysis in myocardial infarction flow grade 〉2 and without death, emergency bypass surgery or disabling cerebral events during the hospitalization. The rate of major adverse cardiac events （MACE）, including death, nonfatal myocardial infarction and target vessel revascularization during follow-up, was recorded.
Results Female patients were more hypertensive and diabetic and with fewer cigarette smokers than male counterparts. The prevalence of angiographic 3-vessel disease was higher in the female group, but the procedural success rate was comparable between the two groups （94.4% vs 92.2%）. The occurrence rate of MACE did not differ during the hospitalization （4.2% vs 6.0%, P=0.50）, but was significantly higher in the female group during follow-up （mean （16.0±11.2） months） than that in the male group （5.4% vs 0.7%, P=0.02）.
Conclusion Despite a similar success rate of primary PCI and in-hospital outcomes in both genders, female patients with acute STEMI still have a worse prognosis during the long-term follow-up.

目的探讨急性ST段抬高型心肌梗死（STEMI）患者急诊经皮冠状动脉介入治疗（PCI）时冠状动脉（冠脉）内注射负荷剂量盐酸替罗非班对心肌灌注及心功能的影响。方法选择2007年7月—2008年12月我科确诊STEMI并接受急诊PCI患者70例,随机分为观察组（36例）和对照组（34例）。两组患者均进行PCI,术中观察组患者给予盐酸替罗非班10μg/kg冠脉内注射,对照组给予等量0.9%氯化钠注射液冠脉内注射。比较两组患者PCI术后即刻造影结果,术后7、30、180 d的左室射血分数（EF）、左室舒张末期内径（LVEDD）、左室收缩末期内径（LVESD）及术后180 d主要不良心血管事件（MACE）发生率,同时观察住院期间的出血并发症。结果观察组患者术后校正TIMI帧数、术后2 h ST段回落程度、磷酸肌酸激酶同工酶（CK-MB）峰值及峰值时间均优于对照组,差异有统计学意义（P〈0.05）;梗死相关血管无复流发生率及术后180 d MACE（包括死亡、再梗死、再次靶血管重建）发生率显著低于对照组,差异有统计学意义（P〈0.05）;与对照组比较,观察组术后7、30、180 d的EF显著增加,LVEDD、LVESD显著降低,差异有统计学意义（P〈0.05）。两组住院期间出血并发症的发生率间差异无统计学意义（P〉0.05）。结论对于STEMI患者行急诊PCI术中联合冠脉内注射替罗非班治疗可减少无复流、慢血流现象的发生,改善心肌水平再灌注状态和左室功能,同时不增加出血发生率,有利于提高临床预后。
