[The role of nursing in right heart catheterization. Advantages from peripheral venous access]. / Papel de enfermería en el cateterismo cardiaco derecho. Ventajas del acceso venoso periférico.

INTRODUCTION: Pulmonary hypertension (PH) is a serious disease that requires early diagnosis to achieve a better patient prognosis. Right heart catheterization (RHC) has become the main diagnostic test for this disease, measuring the pressures from the right heart chambers invasively, using a catheter placed through venous access. Nursing performance has an important role in RHC through peripheral venous access due to its well-done skills for canalization and knowledge about the management and care of these accesses. RHC performed through peripheral venous access provide advantages over those performed through central venous access. OBJECTIVE: To analyze the benefits from RHC through peripheral venous access compared to those performed through central venous access, as well as highlighting the role of nursing during this type of procedures. METHOD: A retrospective, descriptive, and observational study was performed for patients who underwent RHC in our center between January 2019 to January 2023. We analyzed clinical characteristics, access, fluoroscopy parameters, periprocedural complications, and hospital admissions. RESULT: A total of 115 patients were included. The average age was 65±12 years, with 58.1% of females. Risk stratification of PH was the reason for conducting RHC in 82.9%. The anterocubital veins became the main approach (72.2%), performed by hemodynamics nurses, while the central venous ones composed the rest (27.8%), which were done by cardiology specialized doctors. We observed a significant reduction in radiation dose in RHC via anterocubital route compared to central venous access (4.4Gycm2 vs 12.5Gycm2 [IQR: 4.5]; P<.001), and it does also in fluoroscopy times (2.3minutes vs 4.6minutes [IQR: 2.6]; P<.001). No complications were recorded, independently of the approach. Patients who underwent a scheduled catheterization were discharged more frequently on the same day of the procedure whether a peripheral approach was performed (77.2%, 44 of 57 patients), in comparison with the central one (28.6%) (P=.001). CONCLUSIONS: The RHC is an essential tool for the diagnosis of PH, achieving nursing such an important role for those performed by peripheral venous access. Peripheral venous access provides benefits and advantages like the reduction of radiation exposure and scan times, reduced hospital stay. All this could bring greater comfort, safety and better quality of care to the patient.

[Relationship between the systolic-diastolic shock index and mortality in myocardial infarction]. / Relación del índice de choque sistólico-diastólico con mortalidad en el infarto miocárdico.

Background: In the emergency room, the shock index was applied to determine the prognosis in various pathologies, such as acute infarction. The shock index is the re-sult of dividing heart rate by the systolic blood pressure. Objective: To determine the relationship between the systolic shock index and the di-astolic shock index as prognostic factors for mortality in acute myocardial infarction with ST segment elevation prior to admission to the Hemodynamics Room. Material and methods: A prolective analytical cross-sectional study was carried out in patients who were admitted to the Hemodynamics Room for cardiac catheterization within a period of 5 months in 2022. The systolic shock index and diastolic shock index were included as independent variables and mortality was the dependent variable. SPSS, version 25, was used and Pearson's chi-square test was used as statistical test, with a p value < 0.05 being significant. Results: 162 patients were analyzed and showed a diastolic shock index > 1.2143 with a sensitivity of 62.5% and a specificity of 77.4% with a p < 0.05. Their systolic shock in-dex was > 0.8908 with a sensitivity of 45.8% and specificity of 91.2%, with a p < 0.05. Conclusion: It was determined that both shock indices are related as mortality prognos-tic factors in acute myocardial infarction with ST elevation prior to admission to the He-modynamic Room.

Resultados: se analizaron 162 pacientes que tuvieron un índice de choque diastólico > 1.2143, con una sensibilidad de 62.5% y una especificidad de 77.4%, con una p < 0.05. Y presentaron un índice de choque sistólico > 0.8908, con una sensibilidad de 45.8% y una especificidad de 91.2%, con una p < 0.05. Conclusión: se determinó que ambos índices de choque tienen relación como factores pronósticos de mortalidad en el infarto agudo al miocardio con elevación del segmento ST antes de su ingreso al Área de Hemodinamia.

[Role of cardiopulmonary exercise test in early diagnosis of pulmonary hypertension in scleroderma patients]. / Utilidad de la ergoespirometría en el diagnóstico precoz de hipertensión pulmonar en pacientes con esclerodermia.

INTRODUCTION: Pulmonary arterial hypertension (PAH) is a severe, high mortality and progressive disease. Early diagnosis and treatment improves the prognosis. Patients with scleroderma disease presents high risk of developing PAH. Established screening strategies - echocardiogram and DETECT algorithm - recognize the disease when it is already advanced. Cardiopulmonary exercise testing (CPET) detects pulmonary vascular injury in earlier stages. METHODS: Prospective study of 52 consecutive patients diagnosed of scleroderma in our health area, during 2 years (2018 and 2019). All of them undergo CPET, in addition to the annual systematic screening. Sensitivity of current PAH screening is compared to CPET. To confirm the presence of PAH, right heart catheterization (RHC) is performed. In case of suspected PAH in CPET, but non-confirmatory right heart catheterization at rest, patients carried out exercise RHC. RESULTS: Fifty-two CPET were performed, of which 16 suggested PAH. Resting RHC confirmed PAH in 5 patients and exercise RHC in 7 (diagnostic sensitivity of CPET together with rest and exercise catheterization of 100%). Of these 16 patients, DETECT had identified 10, of whom resting RHC confirmed PAH in 3 and exercise RHC in 2 (guideline-based diagnostic algorithm sensitivity 70%). CONCLUSIONS: CPET and exercise RHC could detect PAH earlier than established screening in patients with scleroderma disease, allowing early diagnosis.

First record of pediatric cardiovascular interventional procedures performed in a state pediatric catheterization laboratory in El Salvador.

OBJECTIVE: To describe the types of cardiac catheterization that are performed in the only pediatric catheterization laboratory within the public health network of El Salvador, in collaboration with non-profit organizations. MATERIAL AND METHOD: A descriptive, retrospective, cross-sectional study was conducted in the period from May 2022 to January 2023, reviewing the records of all patients who underwent cardiac catheterization. RESULTS: 54 procedures were performed in the catheterization room, 37 female patients. The weight was 20.6 ± 14.5 kg, of the procedures, 47 (87%) were therapeutic and 7 (13%) diagnostic. Occlusion of the ductus arteriosus was performed in 46% of the patients. No complications were reported, the patients were discharged after 12 hours, all supplies were donated by non-profit foundations. CONCLUSIONS: Our catheterization laboratory performs procedures of varied complexity without reporting any major complications to date.

Optical coherence tomography assessment of pulmonary vascular remodeling in advanced heart failure. The OCTOPUS-CHF study.

INTRODUCTION AND OBJECTIVES: Pulmonary vascular remodeling is common among patients with advanced heart failure. Right heart catheterization is the gold standard to assess pulmonary hypertension, but is limited by indirect measurement assumptions, a steady-flow view, load-dependency, and interpretation variability. We aimed to assess pulmonary vascular remodeling with intravascular optical coherence tomography (OCT) and to study its correlation with hemodynamic data. METHODS: This observational, prospective, multicenter study recruited 100 patients with advanced heart failure referred for heart transplant evaluation. All patients underwent right heart catheterization together with OCT evaluation of a subsegmentary pulmonary artery. RESULTS: OCT could be performed and properly analyzed in 90 patients. Median age was 57.50 [interquartile range, 48.75-63.25] years and 71 (78.88%) were men. The most frequent underlying heart condition was nonischemic dilated cardiomyopathy (33 patients [36.66%]). Vascular wall thickness significantly correlated with mean pulmonary artery pressure, pulmonary vascular resistance, and transpulmonary gradient (R coefficient=0.42, 0.27 and 0.32 respectively). Noninvasive estimation of pulmonary artery systolic pressure, acceleration time, and right ventricle-pulmonary artery coupling also correlated with wall thickness (R coefficient of 0.42, 0.27 and 0.49, respectively). Patients with a wall thickness over 0.25mm had significantly higher mean pulmonary pressures (37.00 vs 25.00mmHg; P=.004) and pulmonary vascular resistance (3.44 vs 2.08 WU; P=.017). CONCLUSIONS: Direct morphological assessment of pulmonary vascular remodeling with OCT is feasible and is significantly associated with classic hemodynamic parameters. This weak association suggests that structural remodeling does not fully explain pulmonary hypertension.

Hemodynamic profiles in a series of patients undergoing right heart catheterization. Experience in one center of Medellin, Colombia.

OBJETIVO: El objetivo de este estudio fue caracterizar la clasificación hemodinámica de la hipertensión pulmonar en una serie de pacientes llevados a cateterismo cardíaco derecho. MÉTODOS: Se realizó un estudio retrospectivo y se revisaron los registros de los cateterismos cardíacos derechos practicados en personas mayores de 18 años entre enero de 2017 y diciembre del 2018. Se excluyó a aquéllos con datos incompletos o no concluyentes y se definieron los perfiles hemodinámicos de acuerdo con el resultado de la presión en cuña y la resistencia vascular pulmonar. RESULTADOS: Se incluyó a 92 sujetos de los cuales se descartó hipertensión pulmonar en 4. El 26.1% se clasificó como precapilar, 31.8% como poscapilar y 42% como combinada. No hubo diferencias entre los tres grupos en edad y sexo; las presiones pulmonares fueron más elevadas en el grupo de hipertensión pulmonar precapilar. Se encontró presión en cuña elevada en el 73.8% de los pacientes y el cateterismo derecho reclasificó al 35% de los pacientes en un grupo hemodinámico diferente al esperado. En la mayor parte de estos casos se sospechaba HP precapilar por el diagnóstico anterior al procedimiento, pero los perfiles hemodinámicos encontrados correspondieron a hipertensión poscapilar o combinada. CONCLUSIÓN: El cateterismo cardíaco derecho es necesario para la clasificación hemodinámica de la hipertensión pulmonar, que es importante no sólo para el diagnóstico sino para evaluar la causa de la enfermedad. OBJECTIVE: To characterize the hemodynamic classification of pulmonary hypertension in a series of patients undergoing to right cardiac catheterization. METHODS: This is a retrospective study, we analyze the records of all right heart catheterizations performed between January 2017 and December 2018, all patient older than 18 years were included and those with incomplete or inconclusive data were excluded. We identify three hemodynamic profiles according to the result of right heart catheterization. RESULTS: 92 subjects were included and pulmonary hypertension was ruled out in 4 of them; 26.1% were classified as precapillary, 31.8% postcapillary and 42% as combined pulmonary hypertesion. There were no differences between the 3 groups in age or sex, pulmonary pressures were higher in the precapillary pulmonary hypertension group, right catheterization reclassified 35% of the patients in a hemodynamic group in a different from that expected. Precapillary PH was suspected in most of these cases, but the hemodynamic profiles found in cardiac catheterization corresponded to post-capillary or combined pulmonay hypertension. CONCLUSION: Right heart catheterization is necessary for the hemodynamic classification of pulmonary hypertension, which is important not only for diagnosis but also for evaluating the etiology of the disease.

Ischaemic stroke as a complication of cardiac catheterisation. Clinical and radiological characteristics, progression, and therapeutic implications.

INTRODUCTION: Ischaemic stroke is the most common neurological complication of cardiac catheterisation. This study aims to analyse the clinical and prognostic differences between post-catheterisation stroke code (SC) and all other in-hospital and prehospital SC. METHODS: We prospectively recorded SC activation at our centre between March 2011 and April 2016. Patients were grouped according to whether SC was activated post-catheterisation, in-hospital but not post-catheterisation, or before arrival at hospital; groups were compared in terms of clinical and radiological characteristics, therapeutic approach, functional status, and three-month mortality. RESULTS: The sample included 2224 patients, of whom 31 presented stroke post-catheterisation. Baseline National Institutes of Health Stroke Scale score was lower for post-catheterisation SC than for other in-hospital SC and pre-hospital SC (5, 10, and 7, respectively; P=.02), and SC was activated sooner (50, 100, and 125minutes, respectively; P<.001). Furthermore, post-catheterisation SC were more frequently due to transient ischaemic attack (38%, 8%, and 9%, respectively; P<.001) and less frequently to proximal artery occlusion (17.9%, 31.4%, and 39.2%, respectively; P=.023). The majority of patients with post-catheterisation strokes (89.7%) did not receive reperfusion therapy; 60% of the patients with proximal artery occlusion received endovascular treatment. The mortality rate was 12.95% for post-catheterisation strokes and 25% for all other in-hospital strokes. Although patients with post-catheterisation stroke had a better functional prognosis, the adjusted analysis showed that this effect was determined by their lower initial severity. CONCLUSIONS: Post-catheterisation stroke is initially less severe, and presents more often as transient ischaemic attack and less frequently as proximal artery occlusion. Most post-catheterisation strokes are not treated with reperfusion; in case of artery occlusion, mechanical thrombectomy is the preferred treatment.

Percutaneous patent ductus arteriosus closure: Twelve years of experience.

INTRODUCTION: Patent ductus arteriosus, a persistent communication between the descending thoracic aorta and the pulmonary artery, is one of the most common congenital heart defects. Transcatheter occlusion is an effective alternative to surgery and is currently standard of care for most patients. The authors present the results from a single center after twelve years of experience using this technique. METHODS: Retrospective analysis of medical records from all patients referred to a tertiary center for percutaneous ductus closure between January 2006 and September 2018. RESULTS: A total of 221 patients were referred, with a mean age of 5.5 years-old (16 patients were infants, with the youngest aged four months). A Nit-Occlud® coil was used 139 times (62.9%), an Amplatzer™ duct occluder 79 times (35.7%), and vascular plugs were used three times. Percutaneous closure was achieved in every treated patient, with 1.4% maintaining residual shunting. Although higher overall coil device implantation was noted, duct occluder usage has been greater since 2011. Of all the coils, 55% were either 4x4 or 5x4 mm, and 73% of all Amplatzer duct occluders were either 6x4 or 8x6 mm, which correlates to the majority of patients having a small to moderately sized ductus. No complications were noted during the procedure, with a 1.8% post-procedure complication rate (one device embolization after 48 hours and three cases of loss of arterial pulse). CONCLUSIONS: Percutaneous patent ductus arteriosus closure was safe and effective in this setting, with a low global complication rate and similar outcomes to most equivalent centers.

Protein-losing enteropathy managed with percutaneous enlargement of a restrictive atrial septal defect.

Protein-losing enteropathy is one of the most feared complications of the Fontan circulation. The diagnosis of protein-losing enteropathy in this setting should prompt a thorough investigation for the presence of a treatable hemodynamic impairment. In this report, we describe a complete reversal of protein-losing enteropathy following percutaneous enlargement of a restrictive atrial septal defect in a patient with a fenestrated lateral tunnel Fontan and severe mitral stenosis.

[Anesthetic management of neonates undergoing diagnostic and therapeutic cardiac catheterization: a systematic literature review]. / Manejo anestésico de neonatos submetidos a cateterismo cardíaco diagnóstico e terapêutico: uma revisão sistemática da literatura.

BACKGROUND: Several interventional cardiology procedures are required in neonates with congenital heart disease. Interventional cardiology procedures have a higher risk of cardiac arrest compared to other interventions. At present, there is great heterogeneity in the perioperative management of congenital heart disease neonates undergoing diagnostic cardiac catheterization or therapeutic cardiac catheterization. STUDY OBJECTIVES: Primary aim: Provide a systematic review of the most effective and/or safe anesthetic and perioperative management in neonates with congenital heart disease who undergo diagnostic cardiac catheterization or therapeutic cardiac catheterization. Secondary aim: Identify the medications, monitoring parameters and airway management used in the same population. DESIGN: Systematic literature review. SETTING: Catheterization laboratory. METHODS: Literature was searched (December 2017) in electronic databases Medline, EMBASE, ScienceDirect, BIREME-Lilacs-Biblioteca Virtual de la Salud, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects and Health Technology Assessment Database. MAIN RESULTS: From 130 records identified, four studies met inclusion criteria and quality assessment. None of the studies were relevant to the primary objective. Regarding the secondary objectives, one study compared the efficacy and adverse effects of racemic ketamine and its S(+) ketamine enantiomer, one study reported the efficacy of subarachnoid anesthesia for high-risk children undergoing diagnostic cardiac catheterization, one study identified the factors associated to high severity adverse events related to sedation, anesthesia and airway, and one study retrospectively analyzed cardiac catheterization procedures in neonates weighing less than 2.5 kg. CONCLUSION: There are no evidence-based recommendations available for congenital heart disease neonates undergoing cardiac catheterization. More studies are required to evaluate the ideal anesthetic and perioperative management in this population.

Exercise right heart catheterization predicts outcome in asymptomatic degenerative aortic stenosis.

INTRODUCTION AND OBJECTIVES: Degenerative aortic stenosis (DAS) is the most frequent valvular heart disease. It remains unclear how to identify asymptomatic DAS patients with normal left ventricular ejection fraction who have a high probability of event occurrence and would thus benefit from early intervention. Here, we describe a protocol for exercise hemodynamics in true asymptomatic patients with moderate or severe DAS and assess the prognostic value of the data obtained in this population. METHODS: This study involved a prospective single-centre registry of consecutive asymptomatic patients with moderate or severe DAS. Patients underwent cardiopulmonary exercise testing to confirm symptom absence during exercise and then right heart catheterization (RHC) at rest and during exercise. Events were defined as death, surgical aortic valve replacement, or transcatheter aortic valve implantation according to clinical guidelines. RESULTS: Thirty-three patients underwent baseline and exercise RHC. The mean aortic valve area was 1.08 cm2 and the aortic gradient was 39mmHg. The mean pulmonary artery pressure was 21mmHg with a pulmonary artery occlusion pressure of 14mmHg and cardiac output of 5.6 L/min. The mean pulmonary artery pressure at peak exercise was 34mmHg. After a mean follow-up of 27 months, 8 patients experienced an event (24%). There were no differences in baseline variables, aortic valve area, or cardiopulmonary exercise testing parameters between the event and event-free groups. Patients with an event did not have higher pulmonary or filling pressures after peak exercise but had lower pulmonary artery oxygen saturation on effort (median, 48% vs 57%, P=.03). CONCLUSIONS: Exercise RHC is feasible and safe in this population. Peak pulmonary artery oxygen saturation might identify patients with increased risk of serious adverse events.

Spanish Cardiac Catheterization and Coronary Intervention Registry. 28th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2018).

INTRODUCTION AND OBJECTIVES: The Working Group on Cardiac Catheterization and Interventional Cardiology presents its annual report on the activity data for 2018. METHODS: Data were voluntarily provided by participating centers. The information was introduced online and was analyzed by the Steering Committee of the Working Group on Cardiac Catheterization and Interventional Cardiology. RESULTS: In 2018, data were reported by 109 hospitals, 83 of these centers are public. A total of 157 632 diagnostic procedures (140 670 coronary angiograms) were performed. This year, the number of percutaneous coronary interventions increased to 72 520 (2.2% increase). There was also an increase in the complexity of coronary interventions: 10.6% in chronic total occlusions and 4.2% in unprotected left main treatment. A total of 21 261 interventional procedures were performed in the acute myocardial infarction setting, of which 91% were primary angioplasties (9.6% higher than in 2017). A total of 108398 stents were implanted, of which 93.8% were drug-eluting stents (3.5% increase). Radial approach was used in 89.4% of interventional procedures. The number of transcatheter aortic valve implantations continued to increase (25.3% increase, n=3537), as well as the number of percutaneous mitral valve repair procedures (21.4% increase, n=328), left atrial appendage closures (10.6% increase, n=644) and patent foramen ovale closures (81% increase, n=514). CONCLUSIONS: An increase in diagnostic and therapeutic procedures was reported in 2018, particularly in primary percutaneous coronary interventions. The use of the radial approach and complex procedures also increased. The number of structural procedures rose significantly, following the trend seen in recent years.

Risk factors and temporal trends for vascular access-related complications in coronary procedures: evolving from femoral to radial approach.

Introduction: Radial access is the gold standard for ST-elevation myocardial infarction; nevertheless, there is scarce information in Mexico. Objectives: The objectives of this study were to describe the differences in radiation exposure, intervention time, fluoroscopy time, complications and temporal trends, and risk factors among radial and femoral access for coronary procedures. Materials and Methods: A total of 493 patients underwent coronary interventions by femoral or radial access. Sociodemographic and procedural data were recorded. A logistic regression model to determine risk factors for complications was performed. Results: The population included 346 men and 147 women, with a median age of 63 years, 159 underwent radial and 334 femoral approaches. Complications occurred in 18 patients (3.6%), 11 in radial and 7 in femoral access, with a higher trend in the first 5 months (n = 14). Vasospasm was the most common (n = 9) complication. Median fluoroscopy time was 12 min for radial and 9 min for femoral groups, with a total radiation dose of 2282 µGm2 and 2848 µGm2, respectively. Temporal trends showed that complications occurred most frequently during the first 6 months of the study. The main predictors for complications were intervention time and one-vessel disease. Conclusions: Radial access had higher frequency of complications than femoral approach and they were more common during the first 6 months. The main risk factor was intervention time longer than 60 min.

Introducción: El abordaje radial es el de elección para infarto de miocardio con elevación del segmento ST, sin embargo se desconoce información en México. Objetivos: Describir las diferencias en exposición a radiación, tiempo de intervención, tiempo de fluoroscopía, complicaciones y sus variaciones temporales, además de los factores de riesgo entre el abordaje radial y el femoral para procedimientos coronarios. Método: Se incluyeron 493 pacientes que fueron sometidos a estudio angiográfico o intervenciones coronarias por abordaje radial o femoral. Se recabaron datos sociodemográficos, antecedentes y variables del procedimiento. Se realizó un modelo de regresión logística para determinar los factores asociados a complicaciones. Resultados: Se incluyeron 346 hombres y 147 mujeres, con mediana de edad de 63 años. A 159 se les realizó acceso radial y a 334 femoral. Las complicaciones ocurrieron en 18 pacientes (3.65%): 11 en radial y 7 en femoral, teniendo mayor incidencia en los primeros 5 meses (n = 14) y siendo el vasoespasmo el más común (n = 9). La mediana de tiempo de fluoroscopía fue de 12 minutos para el radial y de 9 minutos para el femoral, con una dosis total de radiación de 2,282 µGm2 y 2,848 µGm2, respectivamente. Las tendencias temporales indicaron que las complicaciones fueron más frecuentes durante los primeros 6 meses. Los principales predictores fueron el tiempo de intervención y la enfermedad de 1 vaso. Conclusiones: La vía de acceso radial tuvo más complicaciones que la femoral. Se observaron más complicaciones en los primeros 6 meses del estudio. El principal predictor de complicaciones fue el tiempo de intervención mayor a 60 minutos.

Avaliação dos efeitos do curativo compressivo após procedimentos intervencionistas por via radial / Evaluation of the effects of compressive dressing after interventional procedures via radial approach

Introdução: Dispositivos externos compressivos após a punção radial para cateterismo cardíaco e intervenção coronária percutânea visam à hemostasia, ao conforto para o paciente e à segurança. O estudo objetivou avaliar pacientes submetidos a procedimentos coronários invasivos por via radial, nos quais se utilizou um curativo compressivo e de baixo custo, desenvolvido no serviço, avaliando a segurança dele e a ocorrência de complicações. Métodos: Indivíduos submetidos à coronariografia e à intervenção coronária percutânea, avaliados no momento de retirada do curativo compressivo e após 7 dias, por meio de questionário abrangendo comorbidades, quadro clínico, tempo do procedimento e de compressão, avaliação física de hematoma e dor, e Doppler vascular sonoro para avaliação de oclusão da artéria radial. Resultados: Foram avaliados 144 pacientes, sendo 138 com seguimento em 7 dias. Os eventos não diferiram entre procedimentos diagnósticos e terapêuticos. Na avaliação imediata à retirada do curativo, revelou-se incidência de 4,2% de oclusão da artéria radial, com dor referida em 23,6% dos pacientes, graduada em 2,9±1,7 pela Escala Visual Analógica (intensidade de zero a dez) e sem sangramentos graves. Hematoma ocorreu em um paciente (0,9%), com classificação III pelo critério EASY. Na avaliação de 7 dias, a incidência de oclusão da artéria radial foi de 2,2%, a dor foi referida em 11,1% da amostra (intensidade 1,8±0,8), e o hematoma foi evidenciado em 3,5%. Conclusão: O curativo compressivo mostrou-se um procedimento seguro, com baixa taxa de complicações e baixa taxa de dor local nos pacientes submetidos a procedimentos coronários invasivos pela via radial.

Background: External compressive devices after radial puncture for cardiac catheterization and percutaneous coronary intervention aim at hemostasis, patient comfort, and safety. The objective of the study was to evaluate patients undergoing invasive coronary procedures by radial approach, in which a low-cost compressive dressing developed at the service was used, assessing its safety and the occurrence of complications. Methods: Patients undergoing coronary angiography and percutaneous coronary intervention, evaluated at the time of removal of compressive dressing and after 7 days, by means of a questionnaire addressing comorbidities, clinical picture, procedure and compression time, physical assessment of hematoma and pain, and a vascular Doppler ultrasound to evaluate radial artery occlusion. Results: A total of 144 patients were evaluated, 138 of whom were followed up within 7 days. Events did not differ among diagnostic and therapeutic procedures. In the immediate evaluation after removal of dressing, an incidence of 4.2% of radial artery occlusion was observed, with pain reported by 23.6% of patients, graded at 2.9±1.7 points in the Visual Analogue Scale (intensity of zero to ten), and no major bleeding. Hematoma occurred in one patient (0.9%), classified as type III according to the EASY criteria. In the 7-day evaluation, the incidence of radial artery occlusion was 2.2%, pain was reported in 11.1% of sample (intensity 1.8±0.8), and hematoma was evident in 3.5%. Conclusion: The compressive dressing proved to be a safe procedure, with a low rate of complications and a low rate of local pain in patients undergoing invasive coronary procedures via radial approach.

Abstract Objective To analyze the acceptability of people undergoing unscheduled cardiac catheterization about a complex nursing intervention (CI) to reduce anxiety. Methods This is a qualitative and evaluative study of the acceptability of 15 participants who underwent cardiac catheterization regarding a nursing CI. Data collection was carried out in the emergency unit of a highly complex hospital in the city of São Paulo, specialized in cardiology. Participants had a diagnosis of Acute Coronary Syndrome and received the CI, consisting of a musical and educational component, called Education and Music Intervention to Reduce Anxiety (EMIRA). Data were collected from September to October 2021, and participants underwent a semi-structured interview. The guiding questions of the interview were elaborated based on Kazdin. The interviews were recorded and transcribed for Bardin's content analysis. To analyze EMIRA participants' participants, Representations of Everyday Life's theoretical contribution was used. Results Acceptability analysis in relation to EMIRA allowed identifying three categories: EMIRA complex intervention: new experience that helps to understand cardiac catheterization; Complex EMIRA intervention: an experience that generates satisfaction; and EMIRA complex intervention: an anxiety-relieving experience. Participants reported feelings of calm, relief, tranquility, satisfaction, and recommended using EMIRA. Conclusion Participants' experience with EMIRA was positive, suggesting good acceptability of CI by people awaiting unscheduled catheterization in the emergency unit.

Spanish Cardiac Catheterization and Coronary Intervention Registry. 27th Official Report of the Spanish Society of Cardiology Working Group on Cardiac Catheterization and Interventional Cardiology (1990-2017).

INTRODUCTION AND OBJECTIVES: To present the annual report of the Working Group on Cardiac Catheterization and Interventional Cardiology on the activity data for 2017. METHODS: Data were voluntarily provided by Spanish centers with a catheterization laboratory. The information was introduced online and was analyzed by the Steering Committee of the Working Group on Cardiac Catheterization and Interventional Cardiology. RESULTS: In 2017, data were reported by 107 hospitals, of which 82 are public. A total of 154 218 diagnostic procedures (138 448 coronary angiograms) were performed (2.2% increase vs 2016). The use of intracoronary diagnostic techniques significantly increased, especially that of pressure wire (23.2% vs 2016, n=7003). In 2017, the number of percutaneous coronary interventions rose to 70 928 (3.2% increase), of which 21 395 interventional procedures were performed in the acute myocardial infarction setting. A total of 105 529 stents were implanted, of which 90.3% were drug-eluting stents (6% increase). Radial access was used in 85.7% of diagnostic procedures and in 88.4% of interventional procedures. The number of transcatheter aortic valve implantations continued to increase (28.2% increase, n=2821), as did the number of left atrial appendage closures (14.8% increase, n=582) and percutaneous mitral valve repair procedures (14.1% increase, n=270). CONCLUSIONS: Diagnostic and therapeutic procedures in acute myocardial infarction increased in 2017. The use of the radial approach and drug-eluting stents also increased in therapeutic procedures. The number of structural procedures rose significantly compared with previous years.

False Positive STEMI Activations in a Regional Network: Comprehensive Analysis and Clinical Impact. Results From the Catalonian Codi Infart Network.

INTRODUCTION AND OBJECTIVES: ST-segment elevation myocardial infarction (STEMI) network activation by a noncardiologist reduces delay times but may increase the rate of false-positive STEMI diagnoses. We aimed to determine the prevalence, predictors, and clinical impact of false-positive activations within the Catalonian STEMI network (Codi Infart). METHODS: From January 2010 through December 2011, all consecutive patients treated within the Codi Infart network were included. Code activations were classified as appropriate if they satisfied both electrocardiogram and clinical STEMI criteria. Appropriate activations were classified as false positives using 2 nonexclusive definitions: a) "angiographic" if a culprit coronary artery was not identified, and b) "clinical" if the discharge diagnosis was other than STEMI. RESULTS: In total, 5701 activations were included. Appropriate activation was performed in 87.8% of the episodes. The rate of angiographic false positives was 14.6%, while the rate of clinical false positives was 11.6%. Irrespective of the definition, female sex, left bundle branch block, and previous myocardial infarction were independent predictors of false-positive STEMI diagnoses. Using the clinical definition, hospitals without percutaneous coronary intervention and patients with complications during the first medical contact also had a false-positive STEMI diagnoses rate higher than the mean. In-hospital and 30-day mortality rates were similar for false-positive and true-positive STEMI patients after adjustment for possible confounders. CONCLUSIONS: False-positive STEMI diagnoses were frequent. Outcomes were similar for patients with a true-positive or false-positive STEMI diagnosis treated within a STEMI network. The presence of any modifiable predictors of a false-positive STEMI diagnosis warrants careful assessment to optimize the use of STEMI networks.

Eficácia da Hidratação Oral na Prevenção da Nefropatia Induzida por Contraste em Indivíduos Submetidos a Intervenções Coronárias Eletivas / Effectiveness of Oral Hydration in Preventing Contrast-Induced Nephropathy in Individuals Undergoing Elective Coronary Interventions

Resumo Fundamento A nefropatia induzida por contraste (NIC) é definida como deterioração da função renal, representada por um aumento da creatinina sérica ≥25% ou ≥0,5 mg/dL até 72 horas após a exposição ao meio de contraste iodado (MCI). A medida preventiva mais eficaz até o momento é a hidratação venosa (HV). Pouco se sabe sobre a eficácia da hidratação oral (HO) ambulatorial. Objetivo Investigar se a HO ambulatorial com água é tão eficaz quanto a HV com solução salina a 0,9% na prevenção de NIC em procedimentos coronarianos eletivos. Métodos Neste estudo observacional retrospectivo, foram analisados prontuários médicos e dados laboratoriais para coletar dados de indivíduos submetidos a procedimentos coronarianos percutâneos com MCI. Os dados coletados entre 2012 e 2015 avaliaram indivíduos que foram submetidos à HV e entre 2016 e 2020 (após a implementação de um protocolo de HO), os indivíduos que foram submetidos à HO em casa antes e depois de procedimentos coronarianos, conforme orientação da equipe de enfermagem. A significância estatística adotada foi de α=0,05. Resultados No total, 116 pacientes foram incluídos neste estudo, 58 no grupo HV e 58 no grupo HO. Observou-se incidência de NIC de 15% (9/58) no grupo que recebeu HV e 12% (7/58) no grupo que recebeu HO (p=0,68). Conclusão O protocolo de HO realizado pelo paciente parece ser tão eficaz quanto o protocolo de HV hospitalar na proteção renal de indivíduos suscetíveis a desenvolver NIC em intervenções coronarianas eletivas. Essas descobertas devem ser testadas em ensaios mais abrangentes.

Abstract Background Contrast-induced nephropathy (CIN) is defined as worsening renal function, represented by an increase in serum creatinine of ≥ 25% or ≥ 0.5 mg/dL up to 72 h after exposure to iodinated contrast medium (ICM). The most effective preventive measure to date is intravenous hydration (IVH). Little is known about the effectiveness of outpatient oral hydration (OH). Objetive To investigate whether outpatient OH with water is as effective as IVH with 0.9% saline solution in preventing CIN in elective coronary procedures. Methods In this retrospective observational study, we analyzed the medical records and laboratory data of individuals undergoing percutaneous coronary procedures with ICM. Data collected between 2012 and 2015 refer to individuals who underwent IVH and those collected between 2016 and 2020 (after implementation of an OH protocol) correspond to individuals who underwent OH at home before and after coronary procedures as instructed by the nursing team. Statistical significance was established at α = 0.05. Results In total, 116 patients were included in this study: 58 in the IVH group and 58 in the OH group. An incidence of CIN of 15% (9/58) was observed in the group that received IVH and an incidence of 12% (7/58) was seen in the group that received OH (p = 0.68). Conclusion The OH protocol, performed by the patient, appears to be as effective as the in-hospital IVH protocol for the renal protection of individuals susceptible to CIN in elective coronary interventions. These findings should be put to test in larger trials.
