ABSTRACT

Objective To investigate the effect of different doses of statins on the clinical efficacy and safety outcome of intravenous thrombolytic therapy of urokinase in patients with acute ischemic stroke(AIS).Methods Based on a large prospective,multicenter study,the Chinese Intravenous Thrombolysis Registry for AIS within 4.5 h of onset(INTRECIS)database,clinical data of 898 patients with urokinase intravenous thrombolysis for AIS were retrospectively analyzed.According to the amount of statin used during hospitalization,the patients were divided into 132 patients in no-statin group,591 patients in conventional statin group and 175 patients in intensive statin group.Clinical outcome measures included 14-day improvement in the National Institutes of Health Stroke Scale(NIHSS)and 90-day excellent prognosis(improved Rankin score≤1 point).Safety measures included recurrent stroke,bleeding events,and 90-day all-cause mortality.Results After adjusting for differences in baseline characteristics(age,coronary heart disease,diabetes,atrial fibrillation,systolic blood pressure,OTT,DNT,previous anti-plate use,blood glucose,and treatment in Class A hospitals),NIHSS scores improved at 14 days after admission and excellent prognosis at 90 days after admission in convention-dose and intensive statin groups were superior to those in no-statin group(P<0.05);Univariate and multivariate analysis of safety outcome indicators showed no statistically significant differences in stroke recurrence and bleeding events among the three groups(P>0.05);The 90-day all-cause mortality was significantly higher in no-statin group(10.6%)than in convention-dose statin group(2.0%)and intensive dose statin group(2.9%)(P<0.01).Conclusions In patients with AIS who were treated with intravenous urokinase thrombolytic therapy,intensive statin use was associated with improved 14-day NIHSS score and near-term prognosis without increasing the risk of stroke recurrence and bleeding events.Statin use is beneficial to reduce mortality.

ABSTRACT

Objective To investigate the clinical efficacy of transjugular intrahepatic portosystemic shunt(TIPS)combined with indwelling catheter-directed thrombolysis for the treatment of portal vein thrombosis(PVT).Methods The clinical efficacy of 307 patients with portal hypertension complicated by PVT,who received successful TIPS combined with indwelling catheter-directed thrombolysis at the Affiliated Beijing Shijitan Hospital of Capital Medical University of China between January 2016 and December 2019,were retrospectively analyzed.Before and after TIPS,the inferior vena cava pressure(IVCP)and portal vein pressure(PVP)were measured,and the pre-TIPS,post-TIPS(before thrombolysis),and post-thrombolysis portal pressure gradient(PPG,PPG=PVP-IVCP)was separately calculated.Reexamination of portal venography DSA was performed to determine the degree of PVT disappearance and whether the shunt was unobstructed.All patients were followed up for one year.Results The pre-TIPS,post-TIPS(before thrombolysis),and post-thrombolysis mean PPG was(24.50±6.91)mmHg,(18.51±5.11)mmHg,and(10.17±3.97)mmHg,respectively.The post-thrombolysis mean PPG was strikingly lower than the pre-thrombolysis values,the differences were statistically significant(P<0.001).Among the 307 patients,complete disappearance of PVT was observed in 221(72.3%),remarkable reduction of PVT in 86(27.7%),and no invalid result was seen.The patients having complete patency of the shunt flow accounted for 85.7%of the 307 patients(261/307),and the patients having partial patency of the shunt flow accounted for 14.3%of the 307 patients(46/307).Forty-two patients developed complications,and no death occurred.All patients were followed up for one year,and the main clinical symptoms were improved or completely disappeared.Among the 307 patients,an increase in thrombus volume was found in 17(5.5%)when compared to their postoperative values,which returned to the first-time postoperative level after local treatment of the thrombus via the TIPS shunt combined with catheter-directed thrombolysis.Within one year after TIPS and thrombolysis,overt hepatic encephalopathy(OHE)occurred in 54 patients(17.6%,54/307).One patient died of hepatic failure 9 months after TIPS,another patient died of cerebral hemorrhage 11 months after TIPS,and all the remaining patients were alive.Conclusion For patients with portal hypertension complicated by PVT,TIPS combined with indwelling catheter-directed thrombolysis is clinically safe and effective.The standardized,systematic management of the whole therapeutic process should be strengthened.(J Intervent Radiol,2024,32:22-27)

ABSTRACT

Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

ABSTRACT

Ischemic stroke (CIS) refers to ischemic necrosis or softening of localized brain tissue caused by cerebral blood circulation disorders, ischemia and hypoxia. The incidence of CIS is the highest among cerebrovascular diseases. Reduced supply of oxygen and nutrients leads to severe loss of neurons and deficits in brain function in stroke patients. Developing treatments for ischemic stroke remains an important challenge in clinical medicine. The antioxidant N-acetylcysteine (NAC) is a precursor of glutathione, and evidence from animal models of ischemic stroke and some clinical studies suggest that NAC can effectively protect the brain from ischemic damage. In this paper, the mechanism of NAC in CIS is described from various aspects, such as anti-oxidation, inhibition of inflammation, protection of cerebral nerve and mitochondrial function, stabilization of arterial plaque and thrombolytic function, aiming to explore the relationship between NAC and CIS in depth from the basic level, and to provide a theoretical basis for the further application of NAC in the prevention and treatment of patients with ischemic stroke.

ABSTRACT

Thrombus is a major factor leading to cardiovascular diseases such as myocardial infarction and stroke. Although fibrinolytic anti-thrombotic drugs have been widely used in clinical practice, they are still limited by narrow therapeutic windows, short half-lives, susceptibility to inactivation, and abnormal bleeding caused by non-targeting. Therefore, it is crucial to effectively deliver thrombolytic agents to the site of thrombus with minimal adverse effects. Based on the long blood circulation and excellent drug-loading properties of human serum albumin (HSA), we employed genetic engineering techniques to insert a functional peptide (P-selectin binding peptide, PBP) which can target the thrombus site to the N-terminus of HSA. The fusion protein was expressed using Pichia pastoris and purified by Ni-chelating affinity chromatography. After being loaded with gold nanoparticles (Au NPs), the fusion protein formed homogeneous and stable nanoparticles (named as PBP-HSA@Au) with a diameter of 17.7 ± 1.0 nm and a zeta potential of -11.3 ± 0.2 mV. Cytotoxicity and hemolysis tests demonstrated the superb biocompatibility of PBP-HSA@Au. Platelet-targeting experiments confirmed the thrombus-targeting ability conferred by the introduction of PBP into PBP-HSA@Au. Upon near-infrared ray (NIR) irradiation, PBP-HSA@Au rapidly converted light energy into heat, thereby disrupting fibrinogen and exhibiting outstanding thrombolytic efficacy. The designed HSA fusion protein delivery system provides a precise, rapid, and drug-free treatment strategy for thrombus therapy. This system is characterized by its simple design, high biocompatibility, and strong clinical applicability. All animal experiments involved in this study were carried out under the protocols approved by the Animal Experiment Ethics Committee of Jiangnan University [JN. No20230915S0301015(423)].

ABSTRACT

Objective:To explore the anxiety level, influencing factors among surrogate decision-makers of patients with acute ischemic stroke during thrombolysis decision-making, and their correlation with decision-making duration.Methods:Acute ischemic stroke patients and their surrogate decision-makers who visited the Emergency Department of the First Affiliated Hospital of Zhengzhou University from September 2019 to December 2021 were selected as the research subjects.Sociodemographic data and disease related data of patients and surrogate decision-makers were collected.Surrogate decision-makers were evaluated with the state-trait anxiety inventory, decision participation expectation scale, Wake Forest physician trust scale, and perceived social support scale.SPSS 26.0 software was used for data processing.Pearson correlation analysis, Spearman correlation analysis and ridge regression analysis were used for statistical analysis.Results:The score of state anxiety of decision-makers was (49.47±9.04), and 18.2% (70/383) of decision-makers had a decision duration exceeding 15 minutes.The score of state anxiety of decision-makers was positively correlated with decision duration ( r=0.189, P<0.001). The influencing factors of state anxiety level of decision-makers included sociodemographic factors (age of decision-makers and patients, relationship between payers and patients, whether decision-makers bear the current medical expenses, type of medical insurance for patients), psychological factors (trust level in physicians, perceived social support), factors related to patient disease (numbers of stroke relapses, National Institutes of Health stroke scale scores for patients), characteristics of the decision-making process (whether patients participate in the decision-making process, and the role of decision-makers in the decision-making process) (all P<0.05). Conclusion:Most surrogate decision-makers experience anxiety.Medical staff should pay attention to the emotions of decision-makers and adopt appropriate communication skills when communicating with informed consent for thrombolysis, alleviate the anxiety of surrogate decision-makers, so as so reduce the decision-making duration.

ABSTRACT

Objective To explore the predictive role of the triglyceride-glucose(TyG)index in patients with acute ischemic stroke(AIS)treated with alteplase thrombolysis and create a comprehensive predictive model integrating multiple factors for assessing patient out-comes.Methods The clinical data of 302 patients with AIS undergoing alteplase intravenous thrombolysis at the Neurology Department of Fushun Central Hospital from January 2019 to October 2022 were retrospectively analyzed.The patients were categorized into a good prognosis group(n= 193)and a poor prognosis group(n= 109)based on their mRS scores at 90 days post-thrombolysis.Univariate and multivariate logistic regression analyses were employed to identify risk factors influencing adverse outcomes and to establish a predictive model.The predictive performance of the model was assessed using receiver operating characteristic(ROC)curve analysis.Results The results of the multivariate logistic regression analysis revealed that pre-thrombolysis high NIHSS score and TyG index≥9.37 were inde-pendent risk factors for unfavorable prognosis in AIS patients.A predictive model for AIS patient prognosis was successfully established:Logit(Y)=-17.167 + 1.681×TyG index+0.147×pre-thrombolysis NIHSS score.The optimal cutoff value for the TyG index was 9.37.The ROC areas under the curve for predicting unfavorable prognosis in AIS patients at 90 days post-thrombolysis were 0.713 for TyG index,0.705 for pre-thrombolysis NIHSS score,and 0.787 for the combined variable(Y),with the combined variable(Y)exhibiting the largest ROC curve area.Conclusion TyG index≥9.37 and pre-thrombolysis high NIHSS score are independent risk factors for poor prognosis.The combined variable the combined variable(Y)has higher predictive efficiency than the separate variables.

ABSTRACT

Objective:To investigate the effects of early percutaneous coronary intervention (PCI) on myocardial perfusion and left ventricular function in patients with acute ST-segment elevation myocardial infarction (STEMI) after thrombolysis.Methods:A total of 108 patients with STEMI treated in the Second Hospital of Hebei Medical University from January 2020 to December 2022 were divided into early PCI following thrombolysis group ( n=65) and primary PCI (pPCI) group ( n=43). The general clinical data, and the parameters of routine echocardiography at 1 day after PCI and before discharge were compared between the two groups. Myocardial contrast echocardiography (MCE) was used to evaluate myocardial perfusion at 1 day after PCI and before discharge. Results:There were no significant differences in general clinical data between the early PCI following thrombolysis group and the pPCI group (all P>0.05). The left ventricular ejection fraction (LVEF) in the early PCI following thrombolysis group and pPCI group before discharge was significantly higher than that on the 1st day after PCI(both P<0.05). The difference of LVEF was significant between the early PCI following thrombolysis group and the pPCI group before discharge and 1 day after PCI ( P<0.05). Compared with 1 day after PCI, the global longitudinal strain (LVGLS) of left ventricle increased in early PCI following thrombolysis group and pPCI group before discharge(both P<0.05). The difference of LVGLS between early PCI following thrombolysis group and pPCI group before discharge and 1 day after discharge was statistically significant( P<0.05). There were no significant differences in left ventricular end-diastolic diameter (LVEDD), left ventricular end-diastolic volume (LVEDV), left atrial volume (LAV), ratio of mitral early diastolic velocity to late diastolic velocity (E/A), mean early diastolic velocity of mitral annulus (Em) and E/Em 1 day after PCI and before discharge between early PCI following thrombolysis group and pPCI group (all P>0.05). MCE showed that the MCE score index of early PCI following thrombolysis group and pPCI group before discharge was significantly lower than that of 1 day after PCI(both P<0.001). Compared to the 1 day after PCI, the early PCI following thrombolysis group showed a significant increase in the proportion of normal microvascular perfusion (nMVP) and a decrease in the proportion of delayed microvascular perfusion (dMVP) and microvascular obstruction (MVO) before discharge (all P<0.05). In contrast, the pPCI group demonstrated a significant decrease in the proportion of both nMVP and dMVP before discharge compared to the first day after PCI (all P<0.05). However, the decrease in the proportion of MVO was not statistically significant ( P>0.05). Conclusions:Early PCI following thrombolysis and pPCI can enhance left ventricular systolic function and myocardial perfusion in patients with acute ST-elevation myocardial infarction. Early PCI following thrombolysis may offer additional advantages in improving left ventricular systolic function and myocardial perfusion.

ABSTRACT

SUMMARY BACKGROUND: Cerebrovascular accident (or stroke) and ischemic heart disease are the the major causes of death in the world. It is estimated that about 85% of strokes are ischemic in origin. Reperfusion therapy in the acute phase of ischemic stroke with a recombinant human tissue plasminogen activator is effective, but some factors influence the success of this treatment. OBJECTIVE: The aim of this study was to evaluate clinical aspects and possible determinants for reperfusion after venous thrombolysis. METHODS: This is a retrospective, cross-sectional, observational study based on a review of hospital records of inpatients diagnosed with ischemic stroke treated with intravenous thrombolysis, the main outcome being reperfusion or not. RESULTS: Data from this study revealed a predominance of females in the group of reperfused patients and males in the non-reperfused group, both maintaining moderate severity on the National Institutes of Health Stroke Scale and admission without statistical significance (p>0.18). In addition, the mean admission severity score was 13.2 for the group of reperfused patients and 14.2 for those not reperfused, and the mean ejection fraction of both groups was within normal functionality, with a mean of 0.50 for reperfused patients and 0.62 for non-reperfused patients. CONCLUSION: We found an association between successful venous chemical thrombolysis reperfusion and lower mortality in patients with acute stroke.

ABSTRACT

Abstract Background and purpose Intravenous Thrombolysis (IVT) prior to Mechanical Thrombectomy (MT) for Acute Ischaemic Stroke (AIS) due to Large-Vessel Occlusion (LVO) remains controversial. Therefore, the authors performed a meta-analysis of the available real-world evidence focusing on the efficacy and safety of Bridging Therapy (BT) compared with direct MT in patients with AIS due to LVO. Methods Four databases were searched until 01 February 2023. Retrospective and prospective studies from nationwide or health organization registry databases that compared the clinical outcomes of BT and direct MT were included. Odds Ratios (ORs) and 95 % Confidence Intervals (CIs) for efficacy and safety outcomes were pooled using a random-effects model. Results Of the 12 studies, 86,695 patients were included. In patients with AIS due to LVO, BT group was associated with higher odds of achieving excellent functional outcome (modified Rankin Scale score 0-1) at 90 days (OR = 1.48, 95 % CI 1.25-1.75), favorable discharge disposition (to the home with or without services) (OR = 1.33, 95 % CI 1.29-1.38), and decreased mortality at 90 days (OR = 0.62, 95 % CI 0.56-0.70), as compared with the direct MT group. In addition, the risk of symptomatic intracranial hemorrhage did not increase significantly in the BT group. Conclusion The present meta-analysis indicates that BT was associated with favorable outcomes in patients with AIS due to LVO. These findings support the current practice in a real-world setting and strengthen their validity. For patients eligible for both IVT and MT, BT remains the standard treatment until more data are available.

ABSTRACT

Resumo A embolia pulmonar (EP) é a terceira maior causa de morte cardiovascular e a principal de morte evitável intra-hospitalar no mundo. O conceito PERT® (do inglês, pulmonary embolism response team) envolve seu diagnóstico e tratamento precoce e multidisciplinar. A trombose venosa profunda (TVP) é a sua causa inicial na maioria dos casos e é responsável por complicações como a recidiva tromboembólica, a síndrome pós-trombótica e a hipertensão pulmonar tromboembólica crônica. Uma abordagem inicial semelhante ao PERT nos casos de TVP ilíaco-femoral grave pode reduzir não apenas o risco imediato de EP e morte, mas também suas sequelas tardias. Novas técnicas percutâneas e aparatos de trombectomia mecânica para o tromboembolismo venoso (TEV) vêm demonstrando resultados clínicos encorajadores. Propomos o desenvolvimento de um conceito ampliado de resposta rápida ao TEV, que envolve não apenas a EP (PERT®) mas também os casos graves de TVP: o time de resposta rápida para o TEV (TRETEV®), ou do inglês Venous Thromboembolism Response Team (VTERT®).


Abstract Pulmonary embolism (PE) is the third leading cause of cardiovascular death and the main cause of preventable in-hospital death in the world. The PERT® (Pulmonary Embolism Response Team) concept involves multidisciplinary diagnosis and immediate treatment. Deep venous thrombosis (DVT) is the initial cause of most cases of PE and is responsible for complications such as chronic thromboembolic recurrence, postthrombotic syndrome, and chronic thromboembolic pulmonary hypertension. An aggressive approach to severe cases of iliofemoral DVT similar to the PERT® system can not only reduce the immediate risk of PE and death but can also reduce later sequelae. New percutaneous techniques and mechanical thrombectomy devices for venous thromboembolism (VTE) have shown encouraging clinical results. We propose the development of an expanded concept of rapid response to VTE, which involves not only PE (PERT®) but also severe cases of DVT: the Venous Thromboembolism Response Team (VTERT®).

ABSTRACT

Resumen A pesar de los avances en la identificación y reco nocimiento de factores de riesgo del accidente cerebro vascular (ACV) isquémico arterial pediátrico hay escasos avances en el tratamiento hiperagudo. Los factores de riesgo más frecuentes son las arteriopatías, cardiopatías y trombofilias. La confirmación temprana con estudios neurorra diológicos es clave para considerar las terapias de re perfusión, que tienen evidencia limitada en pediatría con buen perfil de seguridad. Existe consenso en la utilización de anticoagulación en patología cardioem bólica, enfermedades protrombóticas y antiagregación en arteriopatías. El desafío futuro será lograr una coordinación entre servicios prehospitalarios y centros especializados en ACV, para mejor manejo terapéutico en etapa hiperaguda disminuyendo su morbimortalidad.


Abstract Despite advances in the identification and recogni tion of risk factors for pediatric arterial ischemic stroke, little progress has been made in hyperacute treatment. The most frequent risk factors are arteriopathies, car diopathies, and thrombophilia. Early confirmation with neuroradiological studies is key to consider reperfusion therapies, which have limited evidence in pediatrics but a good safety profile. There is consensus on the use of anticoagulation in cardio-embolic and prothrombotic diseases, and anti platelet therapy in arteriopathies. The future challenge is to improve coordination between prehospital services and specialized stroke centers to improve therapeutic management in the hyperacute stage and reduce morbidity and mortality.

ABSTRACT

The present study assessed incidence, risk factors, in-hospital and short-term outcomes associated with no-reflow in patients undergoing percutaneous coronary intervention (PCI) in STEMI, NSTEMI, unstable angina and stable angina. Out of 449 patients, 42 (9.3%) developed no-reflow. Hypertension, dyslipidemia, obesity and smoking were significant risk factors. There was significant association of no-reflow with left main disease, multiple stents, target lesion length_x0001_ 20 mm and higher thrombus grade. Interestingly, 93 patients (23.4%) of normal flow had myocardial perfusion grade (MPG) of 0/1 with mortality in 9 (10%) patients. No-reflow is associated with poor in-hospital and short-term outcomes with higher incidence of death, cardiogenic shock, heart failure and MACE. Knowledge of risk factors of no-reflow portends a more meticulous approach to improve final outcomes. MPG could be better predictor of outcomes in these patients.

ABSTRACT

Introdução: a terapia trombolítica é a principal medida salvadora adotada em vítimas de acidente vascular cerebral isquêmico (AVCI), adequada para a maioria delas. Entretanto, alguns pacientes não apresentam evolução clínica, piorando o prognóstico, o que constitui uma lacuna científica essencial. Objetivo: analisar os determinantes da não melhora clínica em pacientes com AVC em uso de trombolíticos rt-PA.Método: estudo observacional retrospectivo caso-controle, realizado de 2014 a 2017 por meio de busca ativa de prontuários de pacientes com AVC submetidos à terapia trombolítica em um hospital de referência no Ceará. A falência clínica foi caracterizada como ausência de redução no National Institutes of Health Stroke Scale-Score (NIHSS).Resultados: um total de 139 pacientes incluídos no estudo em uma única unidade de AVC. A média de idade foi de 66,14 anos (variando de 34 a 95). O seguimento de 24 horas foi completado em 100% dos pacientes. Resultado favorável 24 horas pós-trombólise foi observado em 113 pacientes (81,29%), e não houve melhora clínica em 26 (18,7%). A transformação hemorrágica pós-trombólise foi um forte preditor de não melhora (p=0,004), e diabetes foi o principal fator de risco modificável encontrado (p=0,040).Conclusão: diabetes e transformação hemorrágica após trombólise foram identificados como fatores de risco para não melhora clínica em pacientes com AVC agudo submetidos à terapia trombolítica.


Introduction: thrombolytic therapy is the primary saving measure adopted in ischemic cerebrovascular accident (ICVA) victims, adequate for most of them. However, some patients do not show clinical progress, worsening the prognosis, which constitutes an essential scientific gap.Objective: to analyze the determinants of clinical non-improvement in stroke patients who used rt-PA thrombolytic agentes.Methods: retrospective observational case-control study, carried out from 2014 to 2017 through an active search of medical records of CVA patients undergoing thrombolytic therapy in a reference hospital in Ceará. Clinical failure was characterized as no reduction in the National Institutes of Health Stroke Scale-Score (NIHSS).Results: a total of 139 patients enrolled in the study in a single CVA unit. The mean age was 66.14 years (range 34 to 95). The 24-hour follow-up was completed in 100% of patients. A favorable result 24 hours post-thrombolysis was observed in 113 patients (81.29%), and there was no clinical improvement in 26 (18.7%). Post-thrombolysis hemorrhagic transformation was a strong predictor of no improvement (p=0.004), and diabetes was the main modifiable risk factor found (p=0.040).Conclusion: diabetes and hemorrhagic transformation after thrombolysis were identified as risk factors for clinical non-improvement in patients with acute stroke undergoing thrombolytic therapy.

ABSTRACT

Introducción: los síndromes coronarios agudos representan la forma aguda de la cardiopatía isquémica. Esta constituye, en Cuba, la primera causa de muerte en los últimos años. La provincia de Matanzas muestra un comportamiento similar. Objetivo: evaluar las tendencias de morbilidad y letalidad de los pacientes con síndrome coronario agudo en un período de cinco años. Materiales y métodos: se realizó un estudio descriptivo retrospectivo de corte transversal, con 734 pacientes ingresados con síndrome coronario agudo en la Unidad de Cuidados Intensivos Emergentes del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas, entre enero de 2016 y diciembre de 2020. Se caracterizaron los pacientes según variables clínicas. Los datos se extrajeron de las historias clínicas. Se aplicó el test Chi cuadrado. Resultados: hubo una disminución progresiva y continua del total de pacientes con síndrome coronario agudo en los cinco años estudiados. Sobresalió el sexo masculino, con un 53,67 % (p < 0,02). El grupo etario más afectado fue el de 60 a 69 años. El síndrome coronario agudo sin elevación del segmento ST prevaleció en cuatro de los años analizados. Preponderó la instauración del tratamiento trombolítico en el 78,75 % de los pacientes con síndrome coronario agudo con elevación del ST. El total de fallecidos decreció en el período estudiado. Se demostró la importancia de la aplicación de la trombolisis. Conclusiones: en el quinquenio estudiado, disminuyó gradualmente el total de pacientes con diagnóstico de síndrome coronario agudo, y la letalidad por esta causa, en la Unidad de Cuidados Intensivos Emergentes del Hospital Universitario Clínico Quirúrgico Comandante Faustino Pérez Hernández, de Matanzas.


Introduction: acute coronary syndromes represent the acute form of ischemic heart disease. In Cuba, it is the first cause of death in recent years. The province of Matanzas shows similar behavior. Objective: to evaluate morbidity and lethality tendencies of the patients with acute coronary syndrome in a period of five years. Materials and methods: a descriptive, retrospective, cross-sectional study was carried out with 734 patients admitted with acute coronary syndrome in the Emergency Intensive Care Unit of the Clinical Surgical University Hospital Comandante Faustino Perez, of Matanzas, between January 2016 and December 2020. The patients were characterized according to clinical variables. The data were extracted from clinical records. The Chi-square test was applied. Results: there was a progressive and continuous decrease of the total of patients with acute coronary syndrome in the studied five years. Male gender stood up with 53.67% (p < 0, 02). The most affected age group was the 60-69 years one. The acute coronary syndrome without ST segment elevation prevailed in four of the analyzed years. The establishment of the thrombolytic treatment prevailed in 78.75% of the patients with ST segment elevated acute coronary syndrome. The total of deaths decreased in the studied period. The importance of thrombolysis application was demonstrated. Conclusions: the total of patients with diagnosis of acute coronary syndrome and lethality due to this cause gradually decreased in the studied five-year period in the Emergency Intensive Care Unit of the Clinical Surgical Hospital Comandante Faustino Perez Hernandez, of Matanzas.

ABSTRACT

Objectives@#To determine the outcomes for patients with acute stroke improve with early intervention in a series of the first 50 patients with acute ischemic stroke who were thrombolysed at our center. @*Methods@#National Institutes of Health Stroke Scale (NIHSS) scores were recorded by NIHSS-certified nurses-on-duty in their appropriate monitoring sheets in the chart, which was double-checked by the neurology consultant co-author on duty. Source chart entries were cross-checked with logs from the CT scan, pharmacy, and other department records before being collated by the primary author. Means and averages were used to describe the patients’ data.@*Results@#We included the first 50 patients with acute ischemic stroke, eligible for and who consented for thrombolysis. The patients had an average age of 61 years (range: 29 to 87); 32 (64%) were ≥ 60 years; 16 (32%) were male. Male gender (24/50), age ≥ 60 years old (32/50), hypertension (30/50), heart disease (6/30), smoking (7/30), and ethanol intake (9/30) were the most common risk factors. Thirty-five (70%) suffered a moderate stroke. The mean NIHSS of the 50 patients was 12.6 (range: 2 to 28). All but one received intravenous recombinant tissue plasminogen activator (IV rTPA) within 4.5 hours of onset, at a dose of 0.6 to 0.9 mg/kg. Symptomatic hemorrhagic transformation occurred in one (2%); asymptomatic hemorrhagic transformation was seen in three (6%). Fifteen of the 50 (30%) were NIHSS = 0 on discharge; another 18 (36%) showed clinical improvement compared to their status upon admission. Three patients (6%) were mRS = 0; and 30 (60%) were at least ambulatory (mRS ≤ 3) on discharge. Four patients (8%) died, one (2%) from fatal hemorrhagic transformation. Ten patients (20%) developed nosocomial pneumonia; two (4%) had catheter-related urinary tract infections More than half (52%) did not develop any in-hospital complications. The patients were admitted for a mean of 6.6 days (range < 24 hours to 20 days). The average gross bill was ₱56,041.34 (range: ₱8,729.83 to ₱182,054.08); P32,194 was the average amount our Center shouldered per patient (range: zero to ₱154,272.88); almost all were Charity Service patients who used the ₱19,600 Philippine Health Insurance Corporation case rate and the 20% senior citizen discount to help defray the costs of their hospitalization.@*Conclusion@#Stroke thrombolysis can be done in a rural tertiary hospital safely and effectively if with strong government, administration, health care workers, and community support.

ABSTRACT

Central retinal artery occlusion(CRAO), also known as eye stroke, always results in acute and painless visual loss. At present, conservative treatments, such as eye massage, lowering intraocular pressure and vasodilators have little effect on reducing visual loss. Intra-arterial thrombolysis(IAT)has significantly improved prognosis in patients with acute ischemic stroke, thus IAT has been gradually applied in the treatment of CRAO. IAT injects fibrinolytic drugs directly into the ophthalmic artery by a microcatheter, and dissolves the emboli that block the central retinal artery to restore the blood flow of the retina. Theoretically, IAT may be effective for CRAO as what has been found for stroke, but existing clinical studies exhibited inconsistent results. This paper summarizes the feasibility, efficacy, and safety of IAT treatment in CRAO. It will also analyze related factors that affect the prognosis, putting forward potential development directions and providing insights for the further clinical application of IAT.

ABSTRACT

OBJECTIVE@#To observe the effects of acupuncture on neurologic function and serum inflammatory factors in patients after thrombolysis in acute ischemic stroke (AIS).@*METHODS@#A total of 102 AIS patients with onset to treatment time (OTT) ≤3 h were randomly divided into an observation group and a control group, 51 cases each group. In the control group, thrombolysis and conventional medical treatment were applied. On the basis of the treatment as the control group, acupuncture at Shuigou (GV 26), Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6), etc. was applied in the observation group, 30 min each time, once a day. Both groups were treated for 2 weeks. Before and after treatment, the scores of National Institutes of Health stroke scale (NIHSS), modified Rankin scale (mRS), modified Barthel index (MBI) and serum level of homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP) were compared, and the clinical efficacy was evaluated in the two groups.@*RESULTS@#After treatment, the scores of NIHSS, mRS and serum level of Hcy, hs-CRP were decreased compared with those before treatment (P<0.05), while the MBI scores were increased (P<0.05) in the two groups. The scores of NIHSS, mRS and serum level of Hcy, hs-CRP in the observation group were lower than those in the control group (P<0.05, P<0.01), the MBI score in the observation group was higher than that in the control group (P<0.01). The total effective rate was 88.2% (45/51) in the observation group, which was superior to 70.6% (36/51) in the control group (P<0.05).@*CONCLUSION@#Acupuncture could promote the recovery of neurologic function in patients after thrombolysis in AIS, improve the ability of daily living, which may be related to reducing the level of inflammatory factors, thus inhibiting inflammatory response and improving cerebral ischemia reperfusion injury.

ABSTRACT

Objective To compare the clinical effects of three treatment methods including systemic thrombolysis(ST),catheter-directed thrombolysis(CDT),and AngioJet percutaneous mechanical thrombectomy(PMT)in acute lower extremity deep venous thrombosis(LEDVT). Methods The data of 82 patients diagnosed with LEDVT in the Department of Vascular and Gland Surgery of the First Affiliated Hospital of Hebei North University from January 2017 to December 2020 were collected.The patients were assigned into a ST group(n=50),a CDT group(n=16),and a PMT group(n=16)according to different treatment methods.The efficacy and safety were compared among the three groups. Results Compared with that before treatment,the circumferential diameter difference of both lower limbs on days 1,2,and 3 of treatment in the ST,CDT,and PMT groups reduced(all P<0.001).The PMT group showed smaller circumferential diameter difference of lower limbs on days 1,2,and 3 of treatment than the ST group(all P<0.001)and smaller circumferential diameter difference of the lower patellar margin on day 1 of treatment than the CDT group(P<0.001).The PMT group showed higher diminution rate for swelling of the affected limb at the upper and lower edges of the patella than the ST group(P<0.001)and higher diminution rate for swelling at the upper edge of the patella than the CDT group(P=0.026).The incidence of complications after treatment showed no significant differences among the three groups(all P>0.05).The median of hospital stay in the PMT group was shorter than that in the ST and CDT groups(P=0.002,P=0.001).The PMT group had higher thrombus clearance rate than the ST group(P=0.002)and no significant difference in the thrombus clearance rate from the CDT group(P=0.361).The vascular recanalization rates in the PMT(all P<0.001)and CDT(P<0.001,P=0.002,P=0.009)groups 3,6,and 12 months after treatment were higher than those in ST group,and there were no significant differences between PMT and CDT groups(P=0.341,P=0.210,P=0.341). Conclusions ST,CDT,and PMT demonstrated significant efficacy in the treatment of LEDVT,and PMT was superior to ST and CDT in terms of circumferential diameter difference of the lower limbs,diminution rate for swelling of the affected limb,thrombus clearance rate,length of hospital stay,and long-term vascular recanalization.There was no obvious difference in safety among the three therapies.

ABSTRACT

Objective:To compare the effectiveness and safety of mechanical thrombus aspiration combined with superior mesenteric artery transcatheter thrombolysis with those of simple superior mesenteric artery transcatheter thrombolysis in the treatment of portal vein-superior mesenteric vein thrombosis.Methods:A retrospective case-control study was used to analyze the clinical data of 27 patients with portal vein thrombosis treated by interventional therapy in Beijing Friendship Hospital Affiliated to Capital Medical University from February 2020 to October 2022. According to different interventional procedures, they were divided into two groups: 13 cases were treated with mechanical thrombus aspiration combined with superior mesenteric artery catheterization thrombolysis (combined treatment group), and 14 cases were treated with superior mesenteric artery catheterization thrombolysis alone (catheterization thrombolysis group). The postoperative and preoperative portal vein thrombus grade, catheterization thrombolysis time, parenteral nutrition time and operation-related complications were observed and compared between the two methods, and the incidence of long-term intestinal necrosis was compared after postoperative follow-up. Measurement data of normal distribution were expressed as mean±standard deviation( ± s), t-test was used for comparison between groups. Counting data were expressed as cases and percentage(%), and comparison between groups was used Chi-square test or Fisher exact probability method. Results:There was significant difference in the grade of portal vein thrombosis between the combined treatment group and the catheterization thrombolysis group( P<0.05). The thrombolytic time of catheterization in the two groups was (2.38±0.74) d and (4.79±1.15) d, respectively, and the time of parenteral nutrition was (4.08±2.87) d and (8.50±3.16) d, respectively. The difference was statistically significant ( P<0.05). There was no significant difference in operation-related complications between the two groups ( P>0.05). There were no severe injury of liver and kidney function in both groups. One patient in each group underwent long-term enterectomy. Conclusions:Mechanical thrombus aspiration combined with superior mesenteric artery thrombolysis is safe and effective in the treatment of portal vein thrombosis. Compared with simple superior mesenteric artery thrombolysis, mechanical thrombus aspiration combined with superior mesenteric artery thrombolysis can increase the rate of thrombus clearance and reduce the time of thrombolysis and parenteral nutrition support.
