Methods Divide the outpatient patients into experimental group (89 patients) and control group (99 patients). Use 0.1 g aspirin for two groups with oral administration once per day. The experimental group is used with 0.9 g allium macrostemon with oral administration three times per day. Observe the generation rate and adverse reaction of vascular events in two groups of patients. Results The Total generation rate of vascular events in the experimental group is 6.7% and the control group is 19.2%,the differences were statistically significant (Plt;0.05); the cerebral infarction generation rate in the experimental group is 1.1% and in the control group is 9.1%,the differences were statistically significant (Plt;0.05). There is no significant difference (Pgt;0.05) in TIA, angina pectoris, myocardial infarction generation rate in two groups. There is no significant difference (Pgt;005) in adverse reaction generation rate of subcutaneous hemorrhage, hematuria, melena, nausea, bellyache. Conclusion Taking aspirin with llium macrostemon can significantly decrease total cardiovascular and cerebrovascular events generation rate and cerebral infarction generation rate in high risk patients, improve the curative effect and the adverse reaction has not been significantly increased.
Objective To systematically assess the clinical efficacy and safety of cilostazol for preventing ischemic stroke recurrence. Methods Such databases as PubMed, The Cochrane Library, EMbase, CNKI, CBM, and VIP were searched for randomized controlled trials (RCTs) on the use of cilostazol to prevent ischemic stroke recurrence (up to November, 2010). Two researchers selected studies and extracted data independently using a designed extraction form. The quality of included trials was evaluated and RevMan 5.0 software was used for meta-analyses. Results Four RCTs involving 3 916 patients were included. The results of meta-analyses showed that there were significant differences between cilostazol and aspirin in terms of hemorrhagic stroke occurrence (RR=0.39, 95%CI 0.24 to 0.61, Plt;0.000 1), headache occurrence (RR=1.99, 95%CI 1.16 to 3.43, P=0.01) and dizziness occurrence (RR=1.43, 95%CI 1.13 to 1.79, P=0.002). Whereas, no significant difference was found between the two groups in terms of ischemic stroke recurrence (RR=0.80, 95%CI 0.61 to 1.04, P=0.10) and transient ischemic attack occurrence (RR=0.93, 95%CI 0.45 to 1.92, P=0.85). Conclusion The current evidence indicates that cilostazol is as effective as aspirin in preventing ischemic stroke recurrence, but with less incidence of hemorrhagic stroke.
ObjectiveTo systematically review the effectiveness and safety of aspirin-clopidogrel combined anti-platelet therapy after coronary artery bypass grafting (CABG). MethodsDatabases including The Cochrane Library (Issue 2, 2013), PubMed, EMbase, CBM, CNKI, WanFang Data and VIP were searched electronically from their inception to September 2013 for randomized controlled trials (RCTs) about aspirin-clopidogrel combined anti-platelet therapy after CABG. Two reviewers selected literature independently according to the inclusion and exclusion criteria. After data extraction and methological quality assessment of the included studies, meta-analysis was performed using RevMan 5.2 software. ResultsA total of six RCTs involving 901 patients were included, of which 449 cases were in the aspirin-clopidogrel group (A+C) and 452 cases were in the aspirin with or without placebo group (A+P). The results of meta-analysis showed that: compared with A+P, A+C significantly reduced occlusion rates of the saphenous vein graft (RR=0.59, 95% CI 0.43 to 0.80, P=0.000 6). But no significant difference was found between the two groups in occlusion rates of the left internal mammary artery graft (RR=0.88, 95% CI 0.35 to 2.18, P=0.78), radial artery graft (RR=0.43, 95% CI 0.13 to 1.46, P=0.18), pleural fluid drainage volume (MD=-1.68, 95%CI-48.69 to 45.32, P=0.94), incidence of major bleeding events (RR=1.20, 95% CI 0.39 to 1.65, P=0.75), major cardiovascular events (OR=0.81, 95% CI 0.38 to 1.72, P=0.58), and mortality within 30 days (RR=0.64, 95% CI 0.17 to 2.44, P=0.52). ConclusionIn reducing occlusion rates of the saphenous vein graft, the A+C group is more effective than the A+P group. Due to the limited quantity and quality of the included studies, the above conclusion still needs to be verified by carrying out more high-quality RCTs.
ObjectiveTo understand the situation of off-label use of aspirin among outpatients in Sun Yatsen Memorial Hospital, so as to provide baseline data for developing off-label drug use policy. MethodsA stratified random sampling method was used to collected prescription data of aspirin among outpatients in 2013. The incidence rates between different types of off-label use of aspirin were determined by chi-square test, and the influence factors of off-label drug use were analyzed by logistic regression model. ResultsA total of 5 023 prescriptions with aspirin were collected and analyzed, with incidence rate of off-label use up to 17.7%. The major category of off-label use was no indication (94.38%). The top 3 no indications were recurrent abortion, infertility and systemic lupus erythematosus. Drug specification, gender, age and prescribed department were the risk factors of off-label use. ConclusionAspirin off-label use is common among outpatients in Sun Yat-sen Memorial Hospital in 2013, especially in obstetrics and gynecology department and assisted reproductive center. The results suggest that more clinical studies about aspirin for reproduction are needed to provide more evidence of drug use, so as to ensure the safety of drug use in special populations and avoid potential medical risk.
Objective To evaluate clinical efficacy of mFOLFOX6 combined with aspirin in treatment of advanced gastric cancer following perioperative period of laparoscopic distal subtotal gastrectomy. Methods One hundred and seven patients with advanced gastric cancer were assigned to observation group (57 cases) and control group (50 cases). The patients in the observation group received the mFOLFOX6 chemotherapy and regular intake of aspirin (100 mg/d) and the control group received the mFOLFOX6 chemotherapy alone. The recurrence or metastasis rate, rate of disease progress, toxicity, median survival time, and 3-year survival rate were compared between the observation group and the control group. Results ① There were no significant differences in the gender, age, pathological type, and so on between the observation group and the control group (P>0.05). ② The rates of toxicity such as the white blood cell reduction, granulocyte reduction, thrombocytopenia had no significant differences in these two groups (P>0.05). ③ The follow-up time was 4–45 months with an average 3.5 years, the rate of disease progress was lower (P=0.032), the median survival time was longer (P=0.043), the cumulative 3-year overall survival (P=0.015) and the cumulative 3-year disease-free survival (P=0.037) were better in the observation group as compared with the control group. Conclusion Preliminary results in this study show that mFOLFOX6 regimen combined with low-dose aspirin could significantly improve efficacy of advanced gastric cancer following perioperative period of laparoscopic distal subtotal gastrectomy, reduce rate of disease progress, and improve survival rate without increasing side effects.
Abstract: Coronary artery bypass grafting (CABG) has become more and more popular, but how to decrease the thrombotic stenosis of saphenous vein grafts remains a tough problem clinically. Some researchers raised that aspirin resistance (AR) may be one of the most principal causes of graft thrombus and many correlative studies have been reported in recent years．In this article, we reviewed and analyzed the concept and evaluation criterion, incidence rate, mechanisms, clinic significance, and preventing strategy of AR, expecting to deepen the understanding of AR and help to optimize the antiplatelet therapy for postCABG patients with AR.
ObjectiveTo compare early postoperative outcomes of Chinese patients undergoing off-pump coronary artery bypass grafting (OPCAB) with or without preoperative discontinuation of aspirin. MethodsClinical data of 354 patients who underwent elective OPCAB in Department of Cardiac Surgery, People's Hospital of Peking University from 2011 to 2012 were retrospectively analyzed. There were 132 patients during year 2011 who discontinued aspirin more than 5 days before OPCAB and were defined as a discontinuation group, including 93 males and 39 females with their age of 36-83 (61.70±8.74) years. There were 222 patients during year 2012 who continued aspirin treatment before OPCAB and were defined as an aspirin group, including 162 males and 60 females with their age of 37-82 (63.26±8.94) years. Postoperative chest drainage, incidence of reexploration for bleeding, in-hospital morbidity and mortality were compared between the 2 groups. Serum cardiac troponin I (cTnI) levels during 4-6 hours, 12-18 hours and 24-48 hours after OPCAB were also compared. ResultsPreoperative clinical characters were not statistically different between the 2 groups (P>0.05). Average number of grafts in the discontinuation group was significantly smaller than that in the aspirin group (3.00±0.89 vs. 3.43±0.93, P=0.001). There was no significant difference in postoperative chest drainage (1 063.75±511.50 ml vs. 1 131.35±460.13 ml, P=0.201), incidence of reexploration for bleeding(0 case vs. 1 case, P=1.000), perioperative myocardial infarction(2 cases vs. 1 case, P=0.647), postoperative acute renal failure(4 cases vs. 7 cases, P=1.000), stroke(1 case vs. 4 cases, P=0.726), mechanical ventilation time(41.46±85.50 hours vs. 52.07±143.59 hours, P=0.441), length of ICU stay(81.46±116.90 hours vs. 79.07±136.43 hours, P=0.867), or in-hospital mortality(0.8% vs. 0.9%, P=1.000)between the 2 groups. Serum cTnI levels during 4-6 hours after OPCAB were not statistically different between the 2 groups (P=0.506). Serum cTnI levels during 12-18 hours and 24-48 hours after OPCAB were statistically different between the 2 groups (P=0.002 and P=0.000). The percentages of patients with cTnI level higher than 4.0 ng/ml during 12-18 hours and 24-48 hours after OPCAB in the aspirin group were significantly lower than those in the discontinuation group (5.4% vs. 16.7%, P=0.001;5.9% vs. 17.4%, P=0.000). ConclusionOPCAB without preoperative discontinuation of aspirin does not increase the risk of postoperative bleeding, in-hospital morbidity or mortality, but can decrease postoperative myocardial injury of Chinese patients undergoing OPCAB.
ObjectiveTo determine the prevalence of aspirin (ASA) resistance in pediatric patients with congenital heart disease and evaluate whether postoperative thrombosis is associated with aspirin resistance.MethodsA total of 52 patients undergoing high-risk congenital cardiac surgery were recruited in a prospective cohort study at Fuwai Hospital from August 2016 to December 2017. There were 29 males and 23 females with a median age of 8 months (6 d to 13 years). The response to aspirin was determined using the thromboelastography with platelet mapping (TEG-PM) system several days after administration. According to the arachidonic acid (AA) inhibition< 50% or not, they were divided into an ASA resistance group (n=14) and an ASA sensitivity group (n=38). Risk factors of ASA resistance were identified using univariate and multivariate analysis. Patients were monitored prospectively for three months for the development of a thrombosis event. ResultsOf 52 children analyzed, 14 (26.9%) were ASA resistance. The prevalence of thrombosis after ASA antiplatelet therapy was 5.9%. Dose escalation based on aspirin testing was performed in 3 of 14 patients, and the ASA sensitivity was observed in 1 patient. No correlation was found between ASA resistance and postoperative thrombosis (r=0.04, P=0.80).ConclusionPostoperative thrombosis is not associated with aspirin resistance in these patients. Our findings also suggest that resistance may be due to lack of aspirin doses, monitoring of aspirin therapy and consideration of dose adjustment or alternative agents for unresponsive patients.
Objective To improve the knowledge of epidemiology, diagnosis and treatment of aspirin induced asthma ( AIA) in China. Methods Thirty-six cases with AIA who were reported in 30 papers in recent 10 years were analyzed retrospectively. Results The drugs which induced AIA in China mainly included acetylsalicylic acid ( aspirin) , ibuprofen ( Fenbid, ibuprofen) , while acetaminophen ( paracetamol,Bufferin, Tylenol ) , phenylpropanoid thiazide ( Piroxicam) , methoxy-naphthalene C acid ( naproxen) ,diclofenac in rare cases. 28. 6% ( 8 /28) of AIA patients were complicated with nasal disease . AIA could occur at all ages, especially for those over 40 years ( 72. 2% , 26 /36) . No significant difference of prevalencein male and female. The onset time of AIA was less than 60min in 71. 4% and gt;120min in 38. 6% . Most patients took the medications by oral ( 83. 3% ,30/36) , but the AIA onset time was not different by different administration route. Conclusions The incidence of AIA increases in recent years because of widely use of NSAIDs. However, no awareness of NSAIDs induced asthma is common in patients and physicians. For asthma patients it must be caution to take antipyretic analgesic anti-inflammatory drugs. If necessary,methoxy-naphthalene C acid ( naproxen) and diclofenac could be better choice.
