New method of intracoronary adenosine injection to prevent microvascular reperfusion injury in patients with acute myocardial infarction undergoing percutaneous coronary intervention

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.     

腺苷对急性心肌梗死病人PCI术后心肌再灌注损伤的临床观察

目的观察腺苷对急性心肌梗死(AM I)患者行PC I后再灌注损伤心肌的保护作用。方法AM I患者分为腺苷组和生理盐水组,行PC I时一组冠脉内推注腺苷,一组推注生理盐水,并测定血浆SOD、MDA、CK-MB峰值。结果腺苷组MDA较生理盐水组低(5.01±0.80 vs 6.97±0.86,P<0.05),腺苷组SOD较生理盐水组高(80.70±3.23 vs 61.63±3.49,P<0.05),腺苷组CK-MB峰值较生理盐水组明显降低(123.6±84.3 vs186.1±92.2,P<0.05)。结论AM I患者行急诊PC I术时冠脉内应用腺苷能减轻心肌再灌注损伤。     

Combined intracoronary streptokinase infusion and coronary angioplasty during acute myocardial infarction

PTCA was performed in 28 patients with acute MI immediately after intracoronary streptokinase administration. Indications were failure to obtain reflow in 16 patients and high-grade residual stenosis in 12. PTCA was successful in 11 of 16 cases of streptokinase failure, increasing the overall reflow rate from 66% to 77%. PTCA reduced residual coronary stenosis by more than 20% in 9 of 12 cases in which streptokinase infusion was successful, with 1 acute reocclusion. The frequency of recurrent ischemic events in hospital was 76% in patients with a stenosis of 90% or greater after streptokinase infusion (no PTCA), 14% when residual stenosis was less than 90%, and 6% after successful PTCA. Late restenosis or reocclusion was documented in 5 of 11 PTCA cases (45%). Immediate PTCA after streptokinase administration produces increased clinical stability in hospital, but late restenosis is frequent.     

冠状动脉内注射腺苷对急性心肌梗死再灌注后无复流的影响

目的 评价冠状动脉内注射腺苷对急性心肌梗死(AMI)再灌注治疗后无复流的影响。方法 共62例行经皮冠状动脉介入治疗（PCI）的AMI患者,被随机分为对照组和腺苷组。以PCI后最终冠脉造影校正的心肌梗死溶栓试验血流帧数（corrected thrombolysis in myocardial infarction frame count,cTFC）为标准,当cTFC≥23时诊断为无复流。PCI前、后采集肘静脉血检测肌酸激酶同工酶(CK-MB)和超敏C反应蛋白(hsCRP)。比较两组无复流发生率及血浆心肌酶和炎症因子的变化。结果 腺苷组中无复流的发生率较对照组明显降低(P<0.05)。腺苷组CK-MB和hsCRP较对照组明显降低(P<0.05)。多元线性回归分析显示CK-MB、hsCRP与无复流显著相关(P<0.05)。结论 AMI患者冠脉内应用腺苷能有效降低无复流的发生,降低血浆心肌酶、炎症因子水平。     

急性心肌梗死患者冠状动脉内抽吸物成分与再灌注水平的关系

目的通过对急性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)术中的抽吸物成分进行病理分析,研究不同抽吸物成分与心肌水平再灌注的关系。方法连续入选STEMI并行急诊PCI的患者150例,其中男性96例,女性54例。术者根据术中情况进行血栓抽吸。抽吸物用福尔马林固定后24 h内送病理科,行光学显微镜检查。根据病理检查结果将患者分为3组:血栓组、斑块组、混合组。分析3组患者的临床情况。结果 150例患者中,因病变迂曲钙化抽吸导管不能通过病变处致抽吸失败的4例,抽吸后未见固态物质未送病理检查的15例。资料完整者131例,其中男性87例,女性44例。抽吸成功率87.33%。3组患者TMP分级0²级的发生率:血栓组:43.86%(25/57),斑块组:14.81%(4/27),混合组:17.02%(8/47),多因素非条件Logistic分析结果显示,抽吸物病理结果为斑块成分是与急诊PCI术后心肌灌注水平关系密切的因素(OR:3.412,P=0.011)。结论 STEMI患者通过抽吸清除斑块成分对改善心肌灌注具有重要作用。     

Factors affecting outcome of coronary reperfusion with intracoronary streptokinase in acute myocardial infarction

Aggressive interventional therapy in acute myocardial infarction (AMI) is expensive, time-consuming and not without significant risk. To determine which patients are most likely to benefit from such therapy, the effects of patient age, reperfusion success, admission left ventricular (LV) function, infarct location, admission clinical class, time from onset of pain to reperfusion and admission electrocardiographic findings on the outcome of coronary reperfusion in AMI were assessed in 292 prospectively studied, sequential patients from August 1980 to January 1984. Two hundred ten patients received intracoronary streptokinase (SK) therapy on admission and 82 patients, who either refused the protocol or met exclusion criteria, served as control subjects. Patients older than 65 years showed little improvement in 1-year mortality risk and no significant improvement in LV function during hospitalization after treatment with intracoronary SK. The remaining patients, 178 treated with SK and 48 control, were well matched and served as the basis for further comparisons. In this subgroup of patients, reperfusion success was associated with improved survival and LV function (mortality rate 3%, vs 17% in control subjects; increase in ejection fraction [EF] 18% vs 4%). Patients with an EF of less than 45% on admission showed a 21 +/- 30% increase in EF, compared with an increase in control subjects of 8 +/- 19%, and a lower 1-year mortality rate than controls (6% vs 21%, p = 0.01). Patients with anterior AMI had a significant increase in EF in the SK group (22 +/- 31%) and lower mortality compared with control subjects (5% vs 25%, p = 0.003).(ABSTRACT TRUNCATED AT 250 WORDS)

Factors influencing probability of reperfusion with intracoronary ostial infusion of thrombolytic agent in patients with acute myocardial infarction

A multivariate logistic regression equation was used to evaluate variables related to successful intracoronary thrombolytic therapy. One hundred seventeen patients with a totally occluded infarct-related artery were randomly given ostial infusions of urokinase or streptokinase in a blinded study. The opening rate was 57%. The agent used and time from onset of symptoms to beginning of treatment did not significantly influence opening rate (p greater than .25). The site of occlusion was a strong predictor of opening rate (p = .0004). The anterior descending coronary artery was successfully opened more frequently than the left circumflex or right coronary artery (p = .012). Presence of collaterals adversely affected the recanalization rate in all groups (p = .0004). These variables had an additive effect on the probability of opening. Patients with proximal anterior descending occlusion and no collaterals had a 90% recanalization rate, while those with distal occlusions in vessels other than the anterior descending and with collaterals had only a 24% chance for reperfusion. Thus location of occlusion and presence or absence of collaterals may strongly influence opening rates.     

冠状动脉内应用维拉帕米对急性心肌梗死急诊介入治疗后冠状动脉灌注、心肌灌注和临床预后的影响

目的探讨急性ST段抬高性心肌梗死（STEMI）急诊经皮冠状动脉介入治疗（PCI）时冠状动脉内应用维拉帕米对冠状动脉灌注、心肌灌注及临床预后的影响。方法本研究为前瞻性、随机、双盲、对照性临床研究。连续性入选99例STEMI拟行急诊PCI的患者,随机分为维拉帕米组与对照组。在支架释放后即刻,维拉帕米组在靶血管内注入维拉帕米200μg,对照组在靶血管内注入肝素生理盐水,比较两组PCI术前、术后和冠状动脉内注药后的冠状动脉灌注和心肌灌注的差别。冠状动脉灌注以心外膜TIMI血流（TFG）和校正的TIMI血流帧数计数（CTFC）来评价。心肌灌注以TIMI心肌灌注分级（TMPG）和心肌灌注显影（MBG）来评价。并比较两组在PCI术后1周心脏彩色超声结果、住院期间以及随访期间主要心脏不良事件（MACE）发生率上的差别。结果最终91例患者有完整资料,其中维拉帕米组47例,对照组44例,两组临床基本特征和造影特征相仿。维拉帕米组和对照组在术前和支架释放后即刻冠状动脉灌注和心肌灌注各指标差异均无统计学意义（P〉0.05）。冠状动脉内注入维拉帕米后,维拉帕米组的CTFC、TFG、MBG、TMPG均较对照组有显著改善,分别为CTFC：27.1±14.2比39.0±23.8,P=0.011;TFG≥2级：100%比90.9%,P=0.035;MBG≥2级：91.5%%比75.5%,P=0.034;TMPG≥2级：89.4%比72.7%,P=0.042。维拉帕米组和对照组PCI术后1周时左室射血分数（63.4%±8.2%比63.5%±10.3%,P=0.578）、院内MACE发生率（4.3%比9.1%,P=0.613）和3个月MACE发生率（23.9%比22.7%,P=0.894）差异均无统计学意义。结论STEMI患者急诊行PCI治疗时,冠状动脉内应用维拉帕米可显著改善冠状动脉灌注和心肌灌注水平,但未观察到其对急诊PCI术后心室重构和短期临床预后的显著影响。

Effect of impaired myocardial reperfusion on left ventricular remodeling in patients with anterior wall acute myocardial infarction treated with primary coronary intervention

We assessed the effect of impaired myocardial blush after primary coronary intervention (PCI) on left ventricular remodeling in patients with ST-segment elevation myocardial infarction (STEMI). The study population consisted of 145 patients with first anterior STEMI that was treated successfully (Thrombolysis In Myocardial Infarction grade 3 flow) with PCI. Left ventricular remodeling was defined as an increase of > or =20% in end-diastolic volume based on repeated echocardiographic measurements in patients. The study population was divided into 2 groups according to the presence (myocardial blush grade [MBG] 2 to 3, n = 86) or absence (MBG 0 to 1, n = 59) of myocardial reperfusion. Left ventricular remodeling appeared in 21% of the entire study group. Poor myocardial blush after PCI was associated with an increased rate of remodeling compared with good myocardial reperfusion (32% vs 14%, hazard ratio 2.308, 95% confidence interval [CI] 1.21 to 4.39, p=0.014). Symptoms of heart failure were observed significantly more often in patients with MBG 0 to 1 (35.6% vs 18.6%, p = 0.032) than in patients with MBG 2 to 3. In multivariate analysis, only age (odds ratio 0.96, 95% CI 0.92 to 0.99, p = 0.02) and MBG 0 to 1 (odds ratio 3.15, 95% CI 1.35 to 7.31, p = 0.008) were associated with left ventricular dilation. In conclusion, impaired microvascular reperfusion is associated with left ventricular remodeling and development of congestive heart failure in patients with anterior STEMI that is treated with primary coronary angioplasty.
