ABSTRACT

This study aimed to analyze the incidence of vascular complications and associated factors in patients undergoing elective percutaneous transluminal coronary angioplasty. This study is observational, quantitative, and longitudinal, and followed 50 patients undergoing elective percutaneous transluminal coronary angioplasty. An instrument for the sociodemographic, clinical, procedure, and vascular complications characterization was used for data collection. And descriptive statistics, bivariate analysis, and multiple binomial logistic regression were used for data analysis. The level of statistical significance considered was 95%. It was detected the prevalence of male patients (70%), elderly (54%), and diagnosed with systemic arterial hypertension (72%). As for the percutaneous access route prevailed the radial approach (64%). Age and body mass index were identified as possible risk factors for vascular complications. In the 50 procedures performed, there was a prevalence of hematomas (20%) and bleeding (10%). Among the complications prevailed radial Early Discharge After Transradial Stenting of Coronary (60%), large femoral hematoma (20%), small femoral hematoma (20%), and bleeding (Bleeding Academic Research Consortium 2) (100%). The results concluded an elevated incidence of vascular complications in the first 24 hours after elective percutaneous transluminal coronary angioplasty. This study contributes to research, assistance, and training in health and nursing by identifying post-PTCA vascular complications, minimizing their progression, handling their management, and developing health care safety protocols.

ABSTRACT

Objective: To evaluate the protective effect of jailed balloon technique on side branch (SB) ostium using three-dimensional optical coherence tomography(OCT). Methods: This is a retrospective study. Consecutive coronary disease patients with coronary artery bifurcation lesions who underwent percutaneous coronary intervention (PCI) and completed pre-and post-procedural OCT examinations at the Chinese People's Liberation Army General Hospital from September 2019 to March 2022 were enrolled. Patients were divided into the jailed balloon technique group and the unprotected group according to the options applied for the SB. The SB ostium area difference was calculated from OCT images (SB ostium area difference=post-PCI SB ostium area-pre-PCI SB ostium area). The SB ostium area differences were compared between the two groups and compared further in the subgroup of true bifurcation lesions and non-true bifurcation lesions. In the jailed balloon group, the SB ostium area difference was compared between the active jailed balloon technique and the conventional jailed balloon technique, between the jailed balloon>2.0 mm diameter and the jailed balloon≤2.0 mm diameter, and between the higher balloon pressure (>4 atm, 1 atm=101.325 kPa) and the lower balloon pressure (≤4 atm). Multivariate linear regression analysis was used to explore the correlation between the technical parameters of the jailed balloon technique and the SB protection effect. Results: A total of 176 patients with 236 bifurcation lesions were enrolled, aged (60.7±9.3) years, and there were 128 male patients (72.7%). There were 67 patients in the jailed balloon technique group with 71 bifurcation lesions and 123 patients in the unprotected group with 165 bifurcation lesions. Fourteen patients had 2 to 3 lesions, which were treated in different ways, so they appeared in the unprotected group and the jailed balloon technique group at the same time. The area difference in SB ostium was greater in the jailed balloon group than in the unprotected group (0.07 (-0.43, 1.05)mm2 vs.-0.33 (-0.83, 0.26)mm2, P<0.001), and the results were consistent in the true bifurcation lesion subgroup (0.29 (-0.35, 0.96)mm2 vs.-0.26 (-0.64, 0.29)mm2, P=0.004), while the difference between the two groups in the non-true bifurcation lesion subgroup was not statistically significant (P=0.136). In the jailed balloon technique group, the SB ostium area difference was greater in patients treated with the active jailed balloon technique than in those treated with the conventional jailed balloon technique ((0.43±1.36)mm2 vs. (-0.22±0.52)mm2, P=0.013). The difference in SB ostium area was greater in those using>2.0 mm diameter jailed balloons than in those using≤2.0 mm diameter jailed balloons (0.25 (-0.51, 1.31) mm2 vs.-0.01 (-0.45, 0.63) mm2, P=0.020), while SB ostium area difference was similar between those endowed with higher balloon pressure (>4 atm) compared to those with lower balloon pressure (≤4 atm) (P=0.731). Multivariate linear regression analysis showed that there was a positive correlation between jailed balloon diameter and SB ostium area difference (r=0.344, P=0.019). Conclusions: The jailed balloon technique significantly protects SB ostium, especially in patients with true bifurcation lesions. The active jailed balloon technique and larger diameter balloons may provide more protection to the SB.

ABSTRACT

This retrospective single-center registry study included all consecutive patients who underwent percutaneous coronary intervention (PCI) for a de novo left main coronary artery lesion using drug coated-balloon (DCB)-only strategy between August 2011 and December 2018. To best of our knowledge, no previous studies of DCB-only strategy of treating de novo left main coronary artery disease, exist. The primary endpoint was major adverse cardiovascular events (MACEs) including cardiac death, non-fatal myocardial infarction, and target lesion revascularization (TLR). The cohort was divided into two groups depending on weather the lesion preparation was done according to the international consensus group guidelines. Sixty-six patients (mean age 75±8.6, 72% male), 52% of whom had acute coronary syndrome, underwent left main PCI with the DCB-only strategy. No procedural mortality and no acute closures of the treated left main occurred. At 12 months, MACE and TLR occurred in 24% and 6% of the whole cohort, respectively. If the lesion preparation was done according to the guidelines, the MACE and TLR rates were 21.2% and 1.9%. Left main PCI with the DCB only-strategy is safe leading to acceptable MACE and low TLR rates at one year, if the lesion preparation is done according to the guidelines.

ABSTRACT

Abstract Background: ST-segment elevation acute myocardial infarction (STEMI) is a pathological process that involves cardiac muscle tissue death. Intravenous thrombolysis with fibrinolytics or primary percutaneous coronary intervention (PCI), an invasive technique, can be performed for tissue revascularization. PCI has been preferred as compared to non-invasive methods, although few studies have described its use in Brazil. Objectives: The aim of the present study was to analyze data on the use of primary PCI and investigate the relevance of hospitalizations for the treatment of STEMI in the country. Methods: A descriptive, cross-sectional analysis of data from the Brazilian Unified Health system (SUS) Department of Informatics (DATASUS) from 2010 to 2019 was conducted. Results: Hospitalizations for STEMI represented 0.6% of all hospital admissions in Brazil in the analyzed period, 0.9% of hospital costs, and 2.1% of deaths. The number of hospitalizations due to STEMI was 659,811, and 82,793 for PCIs. Length of hospital stay was 36.0% shorter and mortality rate was 53.3% lower in PCI. The mean cost of PCI was 3.5-fold higher than for treatment of STEMI. Conclusions: Data on hospitalizations for STEMI treatment in Brazil revealed high hospitalization and mortality rates, elevated costs, and long hospital stay. Although primary PCI is a more expensive and less used technique than other methods, it can reduce the length of hospital stay and mortality in the treatment of STEMI.

ABSTRACT

Resumen Justificación: La cardiopatía isquémica es la principal causa de muerte de mujeres en Costa Rica, y su incidencia ha aumentado con los años. A pesar de esto, hay pocos estudios clínicos a este respecto en nuestro país. El objetivo del presente trabajo es presentar las principales características clínicas y angiográficas de un grupo de pacientes con infarto agudo del miocardio con la idea de establecer no solo sus particularidades sino permitir comparaciones con otras poblaciones. Métodos: Se trató de un estudio observacional, descriptivo y retrospectivo, de un periodo de cinco años, en el cual se incluyeron a las pacientes ingresadas con infarto del miocardio a la Unidad de Cuidados Intensivos. Se registraron datos demográficos, de evolución clínica, complicaciones, hallazgos angiográficos, tratamiento y desenlace. El análisis estadístico fue cuantitativo descriptivo, realizado con el programa informático SPSS v.21 (IBM Corp., EEUU) y éste consistió en cálculos de frecuencia, tendencia central, medidas de variabilidad de rango, percentiles, y chi-cuadrado. El protocolo de la investigación fue aprobado por el Comité Ético Científico del Hospital Rafael Ángel Calderón Guardia (DG-3380-2020). Resultados: De 190 pacientes se incluyeron un total de 54. La edad promedio fue de 60 años, con una mortalidad del 17,9%, la cual fue 5,4 % más alta que en los hombres. La mayor parte de las pacientes padecía de hipertensión arterial (74%), 24 (44,5%) eran taba- quistas y 23 (42,5%) tenían diabetes mellitus. Los síntomas más frecuentes fueron: dolor torácico, criodiaforesis y disnea. Se consideró que hubo dolor torácico atípico en 8 casos (15%). A 48 pacientes se le llevó a angioplastia coronaria y solo 35% la recibieron en tiempo oportuno. A 17 pacientes se les aplicó trombólisis farmacológica y solo en 3 pacientes fue exitosa. La arteria coronaria derecha y la arteria descendente anterior fueron los vasos responsables en la mayoría de los casos (19 casos (39,5%) cada uno de ellas.) Conclusión: Esta población tuvo síntomas isquémicos claros, con enfermedad coronaria severa y una mortalidad mayor que los hombres. En general la terapia farmacológica, así como la mecánica se aplicaron en forma tardía.


Abstrac Justification: The ischemic heart disease is the main cause of death of women in Costa Rica, and its incidence has increased with the years. In spite of this, there are few clinical studies in this respect in our country. The aim of this paper is to present the main clinical and angiographic characteristics of a group of patients with acute myocardial infarction in order to establish not only their particularities but also to allow comparisons with other populations. Methods: An observational, descriptive and retrospective study was carried out over a period of five years, in which patients admitted with myocardial infarction to the Intensive Care Unit were included. Demographic data, clinical evolution, complications, angiographic findings, treatment, and outcome were recorded. Statistical analysis was quantitative and descriptive, performed with SPSS v.21 software (IBM Corp., USA) and consisted of calculations of frequency, central tendency, measures of variability, percentiles, and chi-square. The Ethical Committee of the Hospital Rafael Angel Calderon Guardia approved the research protocol (DG-3380-2020). Results: A total of 54 out of 190 patients were included. The average age was 60 years, with a mortality rate of 17.9%, which was 5.4% higher than in men. Most of the patients suffered from arterial hypertension (74%), 24 (44.5%) were smokers and 23 (42.5%) had diabetes mellitus. The most frequent symptoms were chest pain, cryodiaphoresis and dyspnea. It was considered that there was atypical chest pain in 8 cases (15%). Forty-eight patients were taken for coronary angioplasty and only 35% received it in time. Pharmacological thrombolysis was applied to 17 patients, and it was successful in only 3 patients. The right coronary artery and the anterior descending artery were the vessels responsible in most cases (19 cases (39.5%) each). Conclusión: This population had clear ischemic symptoms, with severe coronary disease and higher mortality than men. In general, pharmacological as well as mechanical therapy was applied late.

ABSTRACT

ABSTRACT Background The coronavirus disease (COVID-19) pandemic affected the prompt diagnosis and treatment of Acute myocardial infarction (AMI). Aim: To characterize the clinical profile of patients with AMI during the COVID-19 pandemic, comparing them with a historical cohort. Material and Methods: A case-control study of 96 patients with AMI transferred to a high-volume percutaneous coronary intervention (PCI) hospital between March and July 2020, and a historical cohort of 269 patients transferred during the same period in 2019. Results: When comparing patients transferred during the pandemic with those of the historical cohort, the former were younger (63 ± 12 vs 68 ± 12 years, p 12 hours from the onset of symptoms (44 vs 0%, p < 0.01), a higher median door-to-device time (4 vs 3 hours, p < 0.01), a higher use of primary percutaneous coronary intervention (97 vs 71%, p < 0.01), and higher frequencies of cardiogenic shock (20 vs 4%, p < 0.01) and mechanical complications (10% vs 2%, p < 0.01). Patients during COVID pandemic had a higher thirty-day overall (20 vs 1.4%, p < 0.01) and cardiovascular mortality (13 vs 1%, p < 0.01). During the outbreak, 40% of patients had positive COVID-19 status, which was a predictor for thirty-day overall mortality (Risk ratio 2.90; 95% confidence intervals 1.14-7.36). Conclusions: During the pandemic patients with AMI exhibited delays in consultations and treatment, higher morbidity, and increased mortality. COVID-19 positivity was associated to worse thirty-day overall survival.


Antecedentes: La pandemia COVID-19 afectó el tratamiento oportuno del infarto agudo de miocardio (IAM). Objetivo: Caracterizar el perfil clínico de pacientes con IAM durante la pandemia COVID-19 y compararlos con una cohorte histórica. Pacientes y Métodos: Estudio caso-control de 96 pacientes con IAM transferidos a un hospital de alto volumen de intervención coronaria percutánea (ICP) entre marzo julio de 2020 y una cohorte histórica de 269 pacientes transferidos en el mismo período de 2019 (n = 269). Resultados: Al comparar los pacientes transferidos durante pandemia y la cohorte histórica, los primeros eran más jóvenes (63 ± 12 y 68 ± 12 años respectivamente, p 12 h desde iniciados síntomas de IAM con elevación ST (44,4 y 0% respectivamente, p < 0,01), una mediana de tiempo puerta-guía mayor (4 y 3 horas respectivamente, p < 0,01), un mayor uso de ICP primaria (97 y 71% respectivamente, p < 0,01), mayor frecuencia de shock cardiogénico (19,8 y 4,1% respectivamente, p < 0.01) y complicaciones mecánicas (10,4 y 1,7% respectivamente, p < 0,01). A treinta días, los primeros tuvieron mayor mortalidad general (19,8 y 1,4% respectivamente p < 0.01) y cardiovascular (12,5 y 1,4% respectivamente, p < 0,01). Durante la pandemia, 40% de los pacientes presentó positividad para COVID-19, siendo un factor predictivo de mortalidad general (razón de riesgo 2,90; intervalos de confianza 95% 1,14-7,36). Conclusiones: Durante la pandemia, hubo retrasos en tiempos de consulta y tratamiento y mayor morbimortalidad del IAM. La positividad de COVID-19 se asoció a peor sobrevida general a treinta días.

ABSTRACT

Abstract Background The use of an adequate door-to-balloon time (≤ 90 minutes) is crucial in improving the quality of care provided to patients with ST-segment elevation myocardial infarction (STEMI). Objective To determine the door-to-balloon time in the management of STEMI patients in a cardiovascular emergency department in a hospital of northern Brazil. Methods This was a cross-sectional study based on review of medical records. A total of 109 patients with STEMI admitted to the emergency department of a referral cardiology hospital in Pará State, Brazil, between May 2017 and December 2017. Correlations of the door-to-balloon time with length of hospital stay and mortality rate were assessed, as well as whether the time components of the door-to-balloon time affected the delay in performing primary percutaneous coronary intervention. Quantitative variables were analyzed by Spearman correlation and the G test was used for categorical variables. A p<0.05 was set as statistically significant. Results Median door-to-balloon time was 104 minutes. No significant correlation was found between door-to-balloon time and length of hospital stay or deaths, but significant correlations were found between door-to-balloon time and door-to-ECG time (p<0.001) and ECG-to-activation (of an interventional cardiologist) time (p<0.001). Conclusion The door-to-balloon time was longer the recommended and was not correlated with the length of hospital stay or in-hospital mortality. Door-to-ECG time and ECG-to-activation time contributed to the delay in performing the primary percutaneous coronary intervention. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

ABSTRACT

Objective: To systematically evaluate the efficacy of drug coated balloon (DCB) versus conventional balloon in the treatment of coronary de novo bifurcation lesions. Methods: The databases of PubMed, Embase, Cochrane Library, Web of science, CNKI (China National Knowledge Infrastructure), Wanfang database, VIP, China Biology Medicine disc, Chinese clinical trial registry, American clinical trial registry and cardiovascular related websites until September 2020 were retrieved for collecting the randomized controlled trials (RCT) comparing DCB versus conventional balloon in the treatment of coronary de novo bifurcation lesions. The risk of bias of included studies was assessed using the Cochrane risk assessment tool. The meta-analysis was performed by using Revman 5.3 and Stata 14.0 software. Results: Seven RCTs with a total of 613 patients were included in this meta-analysis. Among the included studies, 4 articles reached the low risk of bias, and the other 3 articles reached the medium risk of bias. The results of meta-analysis showed that there was no significant difference in the major adverse cardiac events (RR=0.65, 95%CI 0.39-1.08, P=0.10), myocardial infarction (RR=0.68, 95%CI 0.25-1.80, P=0.43), target lesion revascularization (RR=0.94, 95%CI 0.53-1.67, P=0.83) between DCB group and conventional balloon group. Late lumen loss of side branch was less in the DCB group than that in the conventional balloon group (WMD=-0.25, 95%CI -0.41--0.09, P<0.01) and the risk of side branch restenosis was also lower in the DCB group than that in the conventional balloon group (RR=0.47, 95%CI 0.22-0.98, P<0.05). However, subgroup analysis showed that the conclusions of domestic studies and foreign studies on late lumen loss and side branch restenosis were inconsistent. The meta-analysis based on domestic literature showed that the risk of side branch restenosis after DCB treatment was lower compared with conventional balloon group (RR=0.29, 95%CI 0.15-0.57, P<0.05), while this parameter derived from foreign literatures remained unchanged between two groups (P=0.53). The meta-analysis results of domestic literature showed that late lumen loss in DCB group was less than that in conventional balloon group (WMD=-0.32, 95%CI -0.51--0.13, P<0.05), but this phenomenon was not observed in foreign literatures (P=0.30). Conclusions: The use of DCB in the treatment of coronary de novo bifurcation lesions has the potential to reduce the rate of restenosis and late lumen loss of side branch compared with conventional balloon group. However, due to the limitation on quantity, quality and results of published studies, more high-quality and large scale RCTs are still needed to confirm these findings.

ABSTRACT

INTRODUCTION@#Early reperfusion of ST-segment elevation myocardial infarction (STEMI) results in better outcomes. Interventions that have resulted in shorter door-to-balloon (DTB) time include prehospital cardiovascular laboratory activation and prehospital electrocardiogram (ECG) transmission, which are only available for patients who arrive via emergency ambulances. We assessed the impact of mode of transport on DTB time in a single tertiary institution and evaluated the factors that affected various components of DTB time.@*METHODS@#We conducted a retrospective cohort study using registry data of patients diagnosed with STEMI in the emergency department (ED) who underwent primary percutaneous coronary intervention. We compared patients who arrived by emergency ambulances with those who came via their own transport. The primary study end point was DTB, defined as the earliest time a patient arrived in the ED to balloon inflation. As deidentified data was used, ethics review was waived.@*RESULTS@#A total of 321 patients were included for analysis after excluding 7 with missing data. The mean age was 61.4±11.4 years old with 49 (15.3%) females. Ninety-nine (30.8%) patients arrived by emergency ambulance. The median DTB time was shorter for patients arriving by ambulance versus own transport (52min, interquartile range [IQR] 45-61 vs 67min, IQR 59-74; @*CONCLUSION@#Arrival via emergency ambulance was associated with a decreased DTB for STEMI patients compared to arriving via own transport. There is a need for public education to increase the usage of emergency ambulances for suspected heart attacks to improve outcomes.

ABSTRACT

Acute myocardial infarction caused by thrombosis of left main coronary artery generate acute cardiac failure, cardiogenic shock and death. Along with the clinical history, the electrocardiogram (EKG) is the most useful tool for its recognition and timely management. Classically the EKG shows ST elevation > 1 mm in aVR or V1 with ST depression in the other leads. Urgent coronary angiography with percutaneous coronary angioplasty using drug eluting stents is recommended when the diagnosis is made. We report two cases to exemplify the clinical presentation, EKG and angiographic findings and therapeutic approach.

ABSTRACT

RESUMEN Con el objetivo de determinar las características clínicas y epidemiológicas de los pacientes con infarto de miocardio agudo (IMA), se realizó un estudio descriptivo en 175 pacientes de un hospital peruano de referencia. La edad promedio de los pacientes fue de 68,7 años y el 74,8% fueron de sexo masculino. La principal estrategia de reperfusión utilizada fue la angioplastia coronaria transluminal percutánea + stent, aunque su uso primario resultó ser bajo; además, el porcentaje de revascularización quirúrgica fue alto. Casi el 60% de los pacientes tuvo una estancia hospitalaria mayor a siete días. La mortalidad intra hospitalaria fue de 3,4%, siendo el shock cardiogénico la causa más frecuente de muerte. Se concluye que el IMA afecta principalmente a varones mayores de 60 años y que la principal estrategia de reperfusión es la angioplastia, además, los tiempos para la realización de la reperfusión son mayores a lo recomendado con porcentajes altos de revascularización quirúrgica.


ABSTRACT To determine the epidemiological and clinical characteristics of patients with acute myocardial infarc tion, a descriptive study was conducted in 175 patients in a referral hospital in Lima. The average age of the patients was 68.7 ± 10.8 years and 74.8% were male. The main reperfusion strategy used was percutaneous transluminal coronary angioplasty + stent, however, the use of primary angioplasty was low (19.5% of patients with ST elevation myocardial infarction). Time to reperfusion therapies (angio plasty or fibrinolysis) were longer than recommended and the percentage of surgical revascularization was high. Almost 60% of the patients had a length of stay longer than seven days. In-hospital mortality was 3.4%, with cardiogenic shock being the most frequent cause of death. Myocardial infarction mainly affects men over 60 years, the clinical and epidemiological variables are like other regional reports. The main reperfusion strategy is angioplasty, although the use of primary angioplasty is low. Time to perfor ming reperfusion is longer than recommended and the percentage of surgical revascularization is high.

ABSTRACT

Introdução. O infarto agudo do miocárdio apresenta significativas taxas de morbimortalidade. A reperfusão precoce por angioplastia primária é a intervenção que reduz a mortalidade e as complicações, e deve ser iniciada em até 12 horas, a fim de impedir a perda muscular irreversível. O tempo entre chegada do paciente ao hospital e a abertura da artéria acometida, tempo porta-balão, determina a morbimortalidade do paciente. Objetivo. Esse estudo busca analisar o potencial benefício do tratamento da reperfusão coronariana precoce, os fatores de risco, as possíveis complicações e o Killip em pacientes que sofreram infarto agudo do miocárdio relacionando-os a sua morbimortalidade. Materiais e métodos. Estudo observacional transversal realizado por meio de coleta de dados dos prontuários dos pacientes submetidos a angioplastia primária de um hospital privado. Resultados. A hipertensão arterial sistêmica foi a variável mais prevalente (75%), e que houve predomínio no sexo masculino (71%) e associação com a progressão da idade. 61% dos pacientes apresentaram um tempo porta balão menor que 90 minutos. Houve significância estatística entre o tempo porta balão e a evolução do Killip, evidenciando um tempo porta-balão maior que 90 minutos na maioria dos pacientes que obtiveram aumento da pontuação do Killip. Conclusão. A precocidade da intervenção no paciente com IAM impacta na morbimortalidade, visto que o tempo porta balão está diretamente associado a evolução da do Killip. Logo, deve-se identificar os fatores que interferem no atendimento, a fim de proporcionar uma intervenção otimizada. (AU)


Introduction. Acute myocardial infarction has significant rates of morbidity and mortality. Early reperfusion by primary angioplasty is the intervention that reduces mortality and complications, and should be started within 12 hours in order to prevent irreversible muscle loss. The time between the patient's arrival at the hospital and the opening of the affected artery, door-to-balloon time, determines the patient's morbidity and mortality. Objective. The proposition of this study is to analyze the potential benefits of early coronary reperfusion, associated with the risk factors, possible complications, and the Killip score in patients whit acute myocardial infarction (AMI) and the relation of those factors with the morbidity and mortality. Materials and methods. This is a transversal observational study and uses data collected of medical records of patients subjected to primary angioplasty in a private hospital. Results. Systemic arterial hypertension was the most prevalent one (75%), it was more common in males (71%) and associated with a higher age. In 61% of the patients port-balloon time was less than 90 minutes. There was statistical significance between port-balloon time and Killip score evaluation, that showed a higher score in patient with a port-balloon time that exceeded 90 minutes. Conclusion. Early intervention in patients with AMI impacts morbimortality, once that the port-balloon time is directly associated with the Killip score results. Therefore, all factors that can lead to a delay in their care of those patients should be identified with the objective of optimize the intervention. (AU)

ABSTRACT

Objective: To investigate the safety and efficacy of regional transport to percutaneous coronary intervention(PCI) hospitals from non-PCI hospitals after thrombolysis in patients with acute ST-segment elevation myocardial infarction(STEMI) in northwest China. Methods: In this retrospective study, 1 062 STEMI patients who were transferred from non-PCI hospitals within 24 hours from symptom onset, during January 2015 and January 2019 in the First Hospital of Lanzhou University, were included. According to the treatment strategy, they were divided into two groups, namely intravenous thrombolysis combined with PCI group(n=240), and primary PCI group(n=822). Observation endpoint were in-hospital adverse cardiovascular and cerebrovascular events and bleeding events, Including all-cause death, ischemic stroke, malignant arrhythmia, intracranial hemorrhage and hemorrhage with hemoglobin decrease≥50 g/L. Results: A total of 1 062 STEMI patients were included(age was (61±12) years old), with 905 males (85.2%). The proportion of grade 0 TIMI blood flow in the primary PCI group before operation was significantly higher than that in the thrombolysis combined with PCI group(63.0%(518/822) vs. 36.3%(87/240), P<0.001). Compared with primary PCI group, the time from symptom onset to first medical contact(2.11(1.00, 4.00)hours vs.3.00(1.13, 7.07)hours, P<0.001) and reperfusion in thrombolysis combined with PCI group(3.07(1.83, 4.87)hours vs. 6.92(4.07, 11.15) hours, P<0.001) were significantly shorter. The proportion of all-cause death was significantly higher in the primary PCI group than that in the thrombolysis combined with PCI group (1.8%(15/822) vs. 0, P=0.03). There was no significant difference in hemorrhage, ischemic stroke and malignant arrhythmia between the two groups(all P>0.05). Conclusions: For STEMI patients initially hospitalized in non-PCI hospitals, regional transport combined with PCI is feasible and effective. It does not significantly increase the risk of bleeding and cardiovascular and cerebrovascular events, with shorter time from symptom onset to myocardial reperfusion.

ABSTRACT

RESUMEN El ejercicio físico evita las enfermedades cardiovasculares pero cuando es intenso debe tener planificación y dosificación correctas y, de ser posible, es muy útil contar con una prueba ergométrica previa y un especialista orientador; porque también puede producir accidentes cardiovasculares en deportistas de alto rendimiento, entre otras cosas, por no cumplir con una programación bien definida con un basamento científico. La complicación más temida es la muerte súbita cardíaca, habitualmente por arritmias malignas y enfermedad isquémica. Se presenta el caso de un deportista de alto rendimiento, de 34 años de edad, en fase desentrenamiento y sin factores de riesgo cardiovascular u otros antecedentes de interés, que sufrió un infarto agudo de miocardio anterior extenso, con angina postinfarto, debido a una estenosis suboclusiva de la descendente anterior proximal. Se realizó angioplastia de rescate, con implantación de un stent farmacoactivo y el paciente evolucionó favorablemente.


ABSTRACT Physical exercise avoids cardiovascular diseases but when it is intense, it must have correct planning and dosage and, if possible, a previous ergometric test and a guidance specialist could be very useful; because it can also cause cardiovascular events in high performance athletes, among other things, for not complying with a well-defined schedule with a scientific base. The most feared complication is sudden cardiac death, usually due to malignant arrhythmias and ischemic heart disease. Here is presented the case of a 34-year-old high-performance athlete, in the detraining phase and without cardiovascular risk factors or other history of interest, who suffered an extensive acute myocardial infarction, with post-infarction angina, due to a stricture suboclusive of the proximal left anterior descending artery. A rescue angioplasty was performed, with implantation of a drug-eluting stent and the patient evolved favorably.

ABSTRACT

The anomalous origin of the coronary arteries is uncommon and the origin of the right coronary artery from the middle third of the anterior descending artery is a finding of extreme rarity. We report two patients with coronary atherosclerotic disease and with an acute coronary syndrome, in whom a single left coronary artery was found. The clinical and angiographic characteristics and the treatment of these patients are described.

ABSTRACT

Se evaluaron las características clínicas, demoras, resultados y morbimortalidad de 1142 pacientes tratados con angioplastia primaria (AP) dentro de las 36 horas del infarto, incluidos en el registro ARGEN-IAM-ST, de carácter prospectivo, transversal, multicéntrico y de alcance nacional. Edades: 61.2 ± 12 años, 88% varones, 20% diabéticos y 58% hipertensos; 77.6% en Killip y Kimball I y 6.2% en shock cardiogénico. El tiempo desde el inicio del dolor hasta el ingreso fue de 153 (75-316) minutos, y puerta-balón de 91 (60-150) minutos. Los casos derivados (17%) tuvieron mayor demora de ingreso, 200 minutos (195-420; p = 0.0001) y mayor tiempo puerta-balón, 113 minutos (55-207); p = 0.099. En 47.6% de los casos la AP se hizo en arteria descendente anterior, en 36.4% a coronaria derecha, en 14.8% a circunfleja y en 1.2% al tronco de coronaria izquierda; en 95% con stent (29% farmacológico). El 95% fue exitoso. El 1.3% presentó angina post-infarto (APIAM), 1.3% re-infarto, 8.8% shock y 3.2% sangrado. Se asociaron a mayor mortalidad edad > 64 años (OR 6.2 (IC 95%: 3.2-12), p < 0.001), diabetes (OR 2.5, IC 95% 1.6-3.9, p < 0.001), re-infarto o APIAM (OR 3.3, IC 95% 1.3-8.3, p = 0.011) y shock (OR 29.2 (15.6-54.8), p < 0.001). La mortalidad hospitalaria del infarto agudo de miocardio con elevación del segmento ST tratado con AP fue de 7.6%. La derivación se asoció a demora de tratamiento. El shock cardiogénico y la isquemia post-infarto se asociaron a alta mortalidad. No hubo variables del procedimiento asociadas a mortalidad.


Our objective was to evaluate clinical characteristics, results and morbi-mortality in primary angioplasty (PA), of patients treated with PA within 36 hours of a myocardial infarction (MI), included in a prospective, transversal, multicenter and national survey (ARGEN-IAM-ST). A total of 1142 patients treated with PA were registered, 61.2 ± 12 years old, 88% male, 20% diabetics and 58% with hypertension; 77.6% in Killip Kimball I and 6.2% in cardiogenic shock. The time from the onset of pain until admission was 153 (75-316) minutes, and door-balloon of 91 (60-150) minutes. The transferred patients (17%) showed longer delay to admission, 200 minutes (195-420; p = 0.0001) and door-to-balloon 113.5 minutes (55-207); p = 0.099. In 47.6% of the cases, the PA was made in the anterior descending artery, in 36.4% in the right coronary artery, in 14.8% in the circumflex artery and in 1.2% in the left coronary artery; in 95% with stent (29% pharmacological); 95% was successful, 1.3% presented post-infarct angina (APIAM), 1.3% re-infarct, 8.8% shock and 3.2% bleeding. Age > 64 years (OR 6.2 (95% CI: 3.2-12), p <0.001), diabetes (OR 2.5, 95% CI 1.6-3.9, p < 0.001), re-infarction or APIAM (OR 3.3, 95% CI 1.3-8.3, p = 0.011) and shock (OR 29.2 (15.6-54.8), p < 0.001) were independently associated with higher mortality. In-hospital mortality of acute myocardial infarction with ST-segment elevation treated with PA was 7.6%. Transference from other center was associated with delay in the admission and treatment. Cardiogenic shock and post-infarct ischemia were associated with high mortality. There were no procedural variables associated with mortality.
