Objective To evaluate effect of duration of clopidogrel use on clinical follow-up outcomes in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention. Methods A total of 214 patients with acute myocardial infarction undergoing primary percutaneous coronary intervention between January 2005 to December 2007 were enrolled. All patients were divided into two groups by duration of clopidogrel use; <1 year group (n=59) and ≥1 years group (n = 155). Baseline characteristics [age, gender, angiographic characteristics, Killip classification, LVEF (left ventricular ejection fraction) , CK (creatine kinase), CK-MB, CTnI (cardiac troponin-I), hemoglobin levels and history of hypertension, diabetes , hyperlipidemia, obesity and smoking ] of two groups were collected. Clinical follow-up end-point was major adverse cardiac event (MACE) including death, acute myocardial infarction, stent thrombosis and stent restenosis. Clinical follow-up duration was 41.6 ± 16.3 months. MACE occurred in 28 patients. Results Rates of male, infarction site .infarction relative artery, multi-vessel disease, Killip classification (class I) , aspirin use and history of smoking, obesity, hypertension and hyperlipidemia were not different ( P > 0. 05) in duration of clopidogrel use < 1 year group and ≥ 1 years group. Average LVEF, hemoglobin levels and rate of drug-eluting stents were significantly lower in duration of clopidogrel use < 1 year group than that in duration of clopidogrel use ≥1 years group (P <0. 0001 ,P <0. 0001 ,P=0. 0065). Average CK、CK-MB.CTnI were significantly higher in duration of clopidogrel use ≥ 1 years group than that in duration of clopidogrel use < 1 year group (P < 0. 0001 ). Rate of diabetes and average age were significantly higher in duration of clopidogrel use < 1 year group than that in duration of clopidogrel use ≥1 years group (P =0. 0190, P <0. 0001 ). Incidence of MACE in follow-up period was significantly lower in duration of clopidogrel use ≥1 years group than that in duration of clopidogrel use < 1 year group (6.45% vs 30. 51% ,P <0. 01). After stopping clopidogrel use, incidence of MACE in follow-up period was significantly lower in duration of clopidogrel use ≥1 years group than that in duration of clopidogrel use < 1 year group (2. 58% vs 20. 34% , P < 0. 01 ) . Conclusion Primary percutaneous coronary intervention is an effective therapeutic method. Incidence of MACE in follow-up period was significantly lower in duration of clopidogrel use ≥1 years group than that in duration of clopidogrel use < 1 year group. Duration of clopidogrel use may influence clinical outcomes in follow-up period in patients with acute myocardial infarction undergoing primary percutaneous coronary intervention.  相似文献

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.  相似文献

Background Aspirin and clopidogrel can improve myocardial reperfusion and alleviate myocardial injury during percutaneous coronary intervention (PCI). Whether the addition of intravenous tirofiban during this procedure produces further benefit has not been clarified in ST segment elevation myocardial infarction (STEMI) patients. We evaluated this on STEMI patients who underwent primary PCI (p-PCI) via transradial artery approach. Methods Consecutive patients were randomized into tirofiban group (n=-72) or placebo group (n=-78). Angiographic analysis included initial and final thrombolysis in myocardial infarction (TIMI) flow grade (TFG), corrected TIMI frame count (CTFC) and TIMI myocardial perfusion grade (TMPG) of the thrombotic vessel. Platelet aggregation rate (PAR), creatine phosphokinase (CPK), CPK isoenzyme MB (CPK-MB) and troponin I levels were measured and TIMI definitions were used to assess bleeding complications. Left ventricular performance parameters were investigated with equilibrium radionuclide ventriculography. Major adverse cardiac events (MACE) were followed up for 6 months. Results The cases of TFG 0 and 1 before PCI, TFG 0 when first crossing of guide wire were less, and the cases of TFG 3 after PCI was more in tirofiban group than those in placebo group. The final CTFC was fewer and the incidence of no reflow phenomenon was lower, as well the percentage of final TFG 3 was higher in tirofiban group than those in placebo group (all P 〈0.05). Mean peak CPK-MB was significantly lower, while the left ventricular performance parameters 1 week after PCI were much more improved in tirofiban group than those in the placebo group. PAR was significantly decreased shortly after tirofiban infusion. The incidence of 6-month MACE in tirofiban group was obviously lower than that in the placebo group. No statistical difference was noted between the two groups with regard to bleeding complications. Conclusions Intravenous tirofiban infusion, in additi  相似文献

Objective: To evaluate the safety and efficacy of antiplatelet therapy of ticagrelor on patients suffering from acute ST segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.Methods: In the study, 96 patients suffering from acute ST segment elevation myocardial infarction onset within 12 h undergoing primary percutaneous coronary intervention from May to October in 2013 were randomly divided into ticagrelor group (n=48) and clopidogrel group (n=48) by using the method of random number table. Ticagrelor and clopidogrel antiplatelet treatment were used before and after operation. Their baseline data, coronary artery disease characteristics, platelet count, adenosine diphosphate(ADP)-induced platelet inhibition rate by thrombelastograph after 5 days of treatment, the major adverse cardiovascular events of the follow up for 6 months and bleeding complications were observed and compared in the two groups. Results: The differences between the two groups of patients with their baseline data, the features of coronary artery lesions, platelet count before and after 5 days of treatment had no statistical significance (P>0.05). ADP induced platelet inhibition rate [(80.2±10.7)%] after 5 days of treatment in ticagrelor group was significantly higher than that in clopidogrel group [(75.3±12.1)%, P<0.05]. The two groups of patients were followed up for 6 months, 8 cases of major adverse cardiovascular events occurred in clopidogrel group, 2 cases of major adverse cardiovascular events occurred in ticagrelor group, and there was significant difference between the two groups (P<0.05). The two groups (7 cases of 48 patients in ticagrelor group vs. 3 cases of 48 patients in clopidogrel group) had no statistically significant difference in bleeding complications (P>0.05).Conclusion: Antiplatelet therapy of ticagrelor on patients suffering from acute ST segment elevation myocardial infarction undergoing emergency PCI has good efficacy and safety.  相似文献

Background The optimal reperfusion strategy in elderly patients with ST-elevation myocardial infarction (STEMI) remains unclear. The purpose of this study was to evaluate the safety, in-hospital and one-year clinical outcomes for patients 〉75 years of age with STEMI receiving primary percutaneous coronary intervention (PCI), compared with those treated by conservative approach. Methods One hundred and two patients 〉75 years of age with STEMI presented 〈12 hours were randomly allocated to primary PCI (n=50) or conservative therapy only (n=52). The baseline characteristics, in-hospital outcome and major adverse cardiac events (MACE), including death, non-fatal myocardial infarction and target vessel revascularization at one-year clinical follow-up were compared between the two groups. Results Age, gender distribution, risk factors for coronary artery disease, infarct site and clinical functional status were similar between the two groups, but the patients in primary PCI group received less low-molecular- weight heparin during hospitalization. Compared with conservative group, the patients in primary PCI group had significantly lower occurrence rate of re-infarction and death and shortened hospital stay. The composite endpoint for in-hospital survivals at 30-day follow-up was similar between the two groups, but one-year MACE rate was significantly lower in the primary PCI group (21.3% and 45.2%, P=0.029). Left ventricular ejection fraction was not significantly changed in both groups during follow-up. Multivariate analysis revealed that primary PCI (OR=0.34, 95% CI: 0.21-0.69, P =0.03) improved MACE-free survival rate for STEMI patients aged 〉 75 years. Conclusion Our results indicated that primary PCI was safe and effective in reducing in-hospital mortality and one-year MACE rate for elderly patients with STEMI.  相似文献

Abstract:
Objective To evaluate the effect of left ventricular ejection fraction (LVEF) on clinical outcomes in patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention. Methods A total of 158 patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention between January 2005 to December 2007were enrolled. They were divided into three groups: LVEF ≤40% ( n = 14), LVEF 41% - 55 % ( n = 46)and LVEF > 55% group ( n = 98 ). The clinical follow-up end-point was major adverse cardiac event (MACE) including death, acute myocardial infarction, stent thrombosis and stent restenosis. The clinical follow-up duration was 43.1 ± 15.2 months. MACE occurred in 15 patients. Results The rates of infarction site, infarction relative artery, 1-vessel disease, 2-vessel disease, hypertension, diabetes, hyperlipidemia,smoking, obesity and aspirin use were not different in three groups (P >0.05). Average CTnI, CK,CK-MB and duration of clopidogrel use were not different in three groups ( P > 0. 05 ). The rate of 3-vessel disease was significantly higher in the LVEF≤40% group than that in the LVEF 41% -55% and LVEF >55% groups (P =0. 0036). The rates of TIMI flow grades (Grade Ⅲ ) and complete revascularization were significantly higher in the LVEF 41% -55% and LVEF >55% groups than that in the LVEF≤40% group ( P =0. 0099 ,P =0. 0010). The rates of Killip classification ( classes Ⅱ , Ⅲ, Ⅳ ) and average symptomonset-to balloon-time (SOTB) were significantly lower in the LVEF 41% -55% and LVEF >55% groups than that in the LVEF ≤ 40% group ( P = 0. 0100, P = 0. 0087 ). The rate of drug-eluting stents was significantly lower in the LVEF≤40% group and LVEF 41% -55% group than that in LVEF >55% group (P = 0. 0242). Logistic regression analysis showed that LVEF was independent predictor for MACE in the follow-up period ( P = 0. 0029 ) . With LVEF decrease, incidence of MACE in the follow-up period significantly increased in LVEF >55% group ,LVEF41% -55% group and LVEF≤40% group(6. 12% vs 8. 7% vs 35.71%, P = 0. 0019). Incidence of total death and cardiac death in the follow-up period significantly increased in LVEF >55% group ,LVEF41% -55% group and LVEF≤40% group( 1.02% vs 4.35% vs 21.43% ,P=0.0090;1.02% vs 2. 17 vs 14.29% ,P=0.0060). Conclusion In patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention,LVEF was independent predictor for MACE in the follow-up period. With LVEF decrease, incidence of MACE in the follow-up period significantly increased.  相似文献

Background Drug-eluting stent (DES) has been used widely for the treatment of patients with acute coronary syndrome with or without diabetes mellitus during percutaneous coronary intervention (PCI), but its long-term safety and efficacy in diabetic patients with acute ST elevation myocardial infarction (STEMI) remain uncertain. This study aimed to investigate the clinical outcomes after primary coronary intervention with DES implantation for diabetic patients with acute STEMI, compared with non-diabetic counterparts. Methods From December 2004 to March 2006, 56 consecutive diabetic patients (diabetic group) and 170 non-diabetic patients (non-diabetic group) with acute STEMI who underwent primary PCI with DES implantation in 3 hospitals were enrolled. Baseline clinical, angiographic, and procedural characteristics, as well as occurrence of major adverse cardiac event (MACE) including cardiac death, non-fatal recurrent myocardial infarction (re-MI) and target vessel revascularization (TVR) during hospitalization and one-year clinical follow-up were compared between the two groups. Results Patients in diabetic group were more hyperlipidemic (69.6% and 51.8%, P=0.03) and had longer time delay from symptom onset to admission ((364±219) minutes and (309±223) minutes, P=0.02) than those in non-diabetic group. The culprit vessel distribution, reference vessel diameter, and baseline TIMI flow grade were similar between the two groups, but multi-vessel disease was more common in diabetic than in non-diabetic group (82.1% and 51.2%, P&lt;0.001). Despite similar TIMI flow grades between the two groups after stenting, the occurrence of TIMI myocardial perfusion grade (TMPG) ≥2 was lower in diabetic group (75.0% vs 88.8% in non-diabetic groups, P=0.02). The MACE rate was similar during hospitalization between the two groups (5.4% vs 3.5%, P=0.72), but it was significantly higher in diabetic group (16.1%) during one-year follow-up, as compared with non-diabetic group (6.5%, P=0.03). The cumulative one-year MACE-free survival rate was significantly lower in diabetic than in non-diabetic group (78.6% vs 90.0%, P=0.02). Angiographic stent thrombosis occurred in 5.4% and 1.2% of the patients in diabetic and non-diabetic group, respectively (P=0.19). All of these patients experienced non-fatal myocardial infarction.Conclusions Although the early clinical outcomes were similar in diabetic and non-diabetic patients with acute STEMI treated with DES implantation, the cumulative MACE-free survival at one-year follow-up was worse in diabetic than in non-diabetic patients. More effective diabetes-related managements may further improve the clinical outcomes of diabetic cohort suffering STEMI.  相似文献

Background Angioplasty in the unprotected left main coronary artery (LMCA) has been controversial. This study aims to evaluate the safety and clinical effectiveness of stenting, including bare metal stent and drug eluting stent (DES), for treatment of unprotected LMCA disease. Methods Between September 1997 and December 2005, a total of 297 consecutive patients underwent percutanous coronary intervention (PCI) on LMCA lesions in our hospital. Their in-hospital data and clinical follow-up outcomes were analyzed and those in pre-DES "'era" (group I, from September 1997 to December 2002) were compared with those in DES "era" (group Ⅱ, from January 2003 to December 2004. Patients in 2005 for the time of follow-up less than one year were not included in this group). Results Altogether 368 coronary stents were successfully deployed in 295 patients. Stents failed to be implanted after balloon predilation in two patients, who received coronary artery bypass graft (CABG) successfully. Bifurcation techniques for distal LMCA executed in 206 patients (69.4%, 2061297), included crossover stenting in 156 (75.7%), T stenting in 4 (1.9%), provisional T stenting in 28 (13.6%), kissing stenting in 5 (2.4%) and stent crushing in 13 (6.3%) patients. During their hospital stay, 5 (1.7%) patients died after PCI procedure, of which 4 died from cardiac origin and one of renal failure. The total in-hospital major adverse cardiac events (MACE) were 2.0% (6/297). In the follow-up period, 19 patients (6.5%) died [15 (5.1%) of cardiac death and 4 of non-fatal myocardial infarction (MI)]. Besides, 2 (0.7%) developed subacute thrombosis (SAT) and 16 (5.4%) performed target lesion revascularization (TLR). The total follow-up MACE was 14.5% (431297). Further analysis also showed that, compared with patients in group I, those in group II apparently had more multi-vessel involvement (14.7% vs 81.9%, P〈0.001), and more bifurcation lesions (32.4% vs 72.2%, P〈0.001). After PCI, in-hospital MACE of group II was significantly lower than that in group I (1.1% vs 9.4%, P〈0.05). And the incidences of MACE, TLR and angiographic restenosis in group II were all significantly lower than those in group I (all P〈0.05) after one year follow-up. Conclusions As new PCI strategies and intervention devices such as DES are developed, coronary stenting, which might have brought better in-hospital and long-term outcomes than CABG are proved to be technically successful and can be safely applied for the treatment of LMCA lesions in the experienced center for coronary intervention.  相似文献

近年新生儿、婴儿、成人麻疹患者逐年增加,临床表现一般仍较典型,成年人麻疹患者全身中毒症状较重。麻疹抗体检测结果阳性是主要的诊断依据。麻疹发病的双相移位的机理可能是,免疫保护力不足,婴儿出生时麻疹抗体力低。孕期母传胎的麻疹抗体减弱,母经乳汁传给婴儿的抗体减弱,成人麻疹抗体水平逐年下降。预防措施是怀孕前给予育龄妇女麻疹疫苗接种,鼓励母乳喂养,麻疹疫苗计划免疫适当提前,在成人追加麻疹疫苗的免疫,加强病毒变异的研究等。  相似文献
