Characteristics of ST-Elevation Myocardial Infarction during the SARS-CoV-2 Outbreak

Abstract Background The SARS-CoV-2 outbreak has led to radical transformation in social, economic, and healthcare systems. This may lead to profound indirect consequences on clinical presentation and management of patients with ST-segment-elevation myocardial infarction. Objectives The objective of this study was to describe the characteristics, management, and outcomes of patients admitted with acute myocardial infarction with ST-segment elevation (STEMI), in two tertiary reference hospitals during the SARS-CoV-2 outbreak and compare them with patients admitted in the previous year. Methods We analyzed data from a multicenter STEMI registry from reference centers in the South Region of Brazil from March 2019 to May 2021. The beginning of the COVID-19 outbreak was considered to be March 2020 and compared to the same period in 2019. Only patients with STEMI submitted to primary percutaneous coronary intervention (PCI) were included in the analysis. Mortality rates were compared with chi-square test. All hypothesis tests had a two-sided significance level of 5%. Results A total of 1169 patients admitted with STEMI were enrolled in our registry, 635 of whom were admitted during the pandemic period. The mean age of our sample was 61.6 (± 12.4) years, and 66.7% of patients were male. Pain-to-door time and door-to-balloon time were longer during the pandemic period. However, there was no difference in mortality rates or major adverse cardiovascular outcomes (MACE). Conclusions We observed a stable incidence of STEMI cases in our registry during the SARS-CoV-2 outbreak with higher pain-to-door time and door-to-balloon time, without any influence on mortality rates however.

Diferenças entre os Sexos nos Desfechos de Pacientes com Infarto do Miocárdio com Supradesnivelamento do Segmento ST Submetidos à Intervenção Coronária Percutânea Primária / Sex Differences in Outcomes of ST Elevation Myocardial Infarction Patients Submitted to Primary Percutaneous Coronary Intervention

Resumo Fundamento Vários estudos têm mostrado que as mulheres não recebem tratamento adequado e apresentam piores desfechos após infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST). Por isso, é necessário investigar questões relacionadas ao gênero para melhor lidar com esse problema no Brasil. Objetivo Determinar se existe associação entre o sexo feminino e eventos adversos em uma coorte contemporânea de pacientes com IAMCSST submetidos à intervenção coronária percutânea primária (ICPp). Métodos Este foi um estudo prospectivo do tipo coorte de pacientes com IAMCSST submetidos à ICPp em um hospital universitário terciário entre março de 2011 e dezembro de 2021. Os pacientes foram categorizados em grupos de acordo com o sexo ao nascimento. O primeiro desfecho clínico foi ECAM em longo prazo. Os pacientes foram acompanhados por um período máximo de cinco anos. Um nível de significância bilateral de 0,05 foi aplicado em todos os testes de hipóteses. Resultados Entre os 1457 pacientes internados por IAMCSST no período do estudo, 1362 foram incluídos e 468 (34,4%) eram do sexo feminino. As mulheres apresentaram maior prevalência de hipertensão (73% vs. 60%, p<0,001), diabetes (32% vs. 25%, p=0,003) e classe Killip 3-4 na internação (17% vs. 12%, p=0,01); o escore de risco TIMI foi maior nas mulheres [4 (2, 6) vs. 3 (2, 5), p<0.001]. A mortalidade hospitalar não foi diferente entre os grupos (12,8% vs. 10,5%; p=0,20). Os ECAMs foram numericamente maiores nas mulheres que nos homens tanto durante a internação (16,0% vs. 12,6%, p=0,085) como em longo prazo (28,7% vs. 24,4%, p=0,089), com significância limítrofe. Após a análise multivariada, o sexo feminino não foi associado a ECAMs (HR = 1,14; IC95% 0,86 - 1,51; p = 0,36). Conclusão Em uma coorte prospectiva contemporânea de pacientes com IAMCSST submetidos à ICPp, pacientes do sexo feminino apresentaram idade mais avançada e mais comorbidades no basal que os pacientes do sexo masculino, mas não houve diferenças significativas entre os sexos quanto aos desfechos adversos no hospital ou em longo prazo.

Abstract Background Several studies have shown that women are usually undertreated and have worse outcomes after ST-segment elevation myocardial infarction (STEMI), hence the need to investigate questions related to sex in Brazil to better deal with the problem. Objective To determine whether female sex is still associated with adverse events in a contemporary cohort of patients with STEMI undergoing primary percutaneous coronary intervention (pPCI). Methods This was a prospective cohort study of STEMI patients submitted to pPCI in a tertiary university hospital between March 2011 and December 2021. Patients were categorized into groups based on their sex at birth. The primary clinical outcome was long-term MACCE. Patients were followed-up for up to five years. All hypothesis tests had a two-sided significance level of 0.05. Results Among 1457 patients admitted with STEMI in the study period, 1362 were included and 468 (34.4%) were women. Female patients had a higher prevalence of hypertension (73% vs. 60%, p <0.001), diabetes (32% vs. 25%, p=0.003) and Killip class 3-4 at hospital admission (17% vs. 12%, p=0.01); TIMI risk score was higher among women (4 [2, 6] vs. 3 [2, 5], p<0.001). In-hospital mortality was not different between groups (12.8% vs. 10.5%, p=0.20). In-hospital MACCE (16.0% vs. 12.6%, p=0.085) and long-term MACCE (28.7% vs. 24.4%, p=0.089) were numerically higher in women, with borderline significance. After multivariate analysis, female sex was not associated with MACCE (HR = 1.14; 95% CI 0.86 - 1.51; p = 0.36). Conclusion In a prospective cohort of STEMI patients submitted to pPCI, female patients were older and had more comorbidities at baseline, but no significant differences were found in terms of long-term adverse outcomes.

Valor prognóstico da amplitude de distribuição das hemácias em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST submetidos à intervenção coronariana percutânea / Prognostic value of red cell distribution width in ST-segment elevation myocardium infarction patients undergoing percutaneous coronary intervention

Objetivo: Determinar os valores da amplitude de distribuição das hemácias em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST submetidos à intervenção coronária percutânea primária e avaliar sua associação com resultados adversos. Métodos: Os níveis de amplitude de distribuição das hemácias foram medidos em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST antes da intervenção coronária percutânea primária e divididos conforme valor das amplitudes de distribuição das hemácias. Após a alta hospitalar, os pacientes foram acompanhados por até 3 anos para a ocorrência de eventos cardiovasculares adversos maiores e mortalidade a longo prazo. Resultados: Foram incluídos 893 pacientes com idade média de 60,7 (±12,5) anos, e 66,3% eram do sexo masculino. Na análise multivariada, a hemácia permaneceu como preditor independente de mortalidade a longo prazo. A área sob a curva para mortalidade a longo prazo foi de 0,64 (IC95% 0,61-0,67; p<0,0001). Amplitudes de distribuição das hemácias <13,3 tiveram valor preditivo negativo de 87,1% para mortalidade por todas as causas. Conclusão: Um valor elevado de amplitude de distribuição das hemácias é um preditor independente de mortalidade a longo prazo e eventos cardiovasculares adversos maiores em pacientes com infarto agudo do miocárdio com supradesnivelamento do segmento ST submetidos à intervenção coronária percutânea primária. Amplitudes de distribuição das hemácias baixas têm baixo tem um excelente valor preditivo negativo para mortalidade a longo prazo. (AU)

Objective: To determine red cell distribution width values in ST-elevation acute myocardial infarction patients undergoing primary percutaneous coronary intervention and to evaluate its association with adverse outcomes. Methods: Red cell distribution width levels were measured in ST-segment elevation myocardial infarction patients before primary percutaneous coronary intervention and divided into low and high red cell distribution width. After discharge, patients were followed for up to 3 years for the occurrence of long-term major adverse cardiovascular events and mortality. Results: A total of 893 patientes were with a mean age of 60.7 (±12.5) years, 66.3% were male. In multivariate analysis, the red cell distribution width remained as an independent predictor of long-term mortality. The area under the curve for long-term mortality was 0.64 (95%CI0.61-0.67; p<0.0001). Red cell distribution width<13.3 had a negative predictive value of 87.1% for all-cause mortality. Conclusion: High number of red cell distribution width is an independent predictor of long-term mortality and major adverse cardiovascular events in ST-segment elevation myocardial infarction patients undergoing primary percutaneous coronary intervention. A low number of red cell distribution width has an excellent negative predictive value for long-term mortality. Patients with sustained elevated levels of red cell distribution width have worse outcomes at long-term follow-up. (AU)

An overview of care change in the last 6 year in primary PCI in ST-elevation myocardial infarction in a Tertiary University Brazilian Hospital / Panorama da mudança do cuidado nos últimos 6 anos na ICP primária em infarto agudo do miocárdio com supradesnivelamento do segmento ST em hospital universitário de nível terciário

Background: Although new studies and guidelines can be considered useful tools, it does not necessarily mean they are put into clinical practice. Objective: The aim of the current analysis was to assess the changes in primary percutaneous coronary intervention (PCI) and mortality in a tertiary university hospital in southern Brazil during a six-year period .Methods: We have included consecutive patients with ST-elevation myocardial infarction (STEMI) who underwent primary PCI between March 2011 and February 2017. Previous clinical history, characteristics of the procedure, and reperfusion strategies were collected. In-hospital, short and long-term mortalities were also evaluated. The significance level adopted for all tests was 5%. Results: There was an increase in the use of radial access in patients from 20.0% in 2011 to 62.7% in 2016 (ptrend < 0.0001). Moreover, thrombus aspiration decreased significantly from 66.7% in 2011 to less than 3.0% in 2016 (ptrend < 0.0001). In-hospital, short and long-term mortalities remained reasonably stable from 2011 to 2016 (ptrend > 0.05). However, a lower in-hospital mortality was observed in patients treated through radial access (p < 0.001). Cardiogenic shock occurred in 11.1%, without statistical differences in the period (ptrend = 0.39), while long-term mortality rate decreased from 80.0% in 2011 to 27.3% in 2016 in this patient group (ptrend = 0.29). Conclusions: During a 6-year follow-up period, primary PCI characteristics underwent important modifications. Radial access became widely used, with a decrease in mortality with the use of this route, while aspiration thrombectomy became a rare procedure. The incidence of cardiogenic shock remained stable, but has shown a reduction in its mortality

Comparação de escores anatômicos e clínicos na predição de desfechos em intervenções coronárias percutâneas primárias / Comparison of anatomical and clinical scores in predicting outcomes in primary percutaneous coronary intervention

Fundamento: Diferentes escores baseados em variáveis anatômicas e/ou clínicas têm sido desenvolvidos para estratificação de risco em pacientes submetidos à intervenção coronariana percutânea (ICP). Estudos comparando a capacidade desses modelos na predição de eventos cardíacos e cerebrovasculares adversos maiores (ECCAM) em pacientes submetidos à ICP primária são escassos. Objetivo: O objetivo desse estudo foi o de comparar os escores SYNTAX (SS), Clinical SYNTAX (CSS), ACEF e ACEF modificado (ACEF Mod ) na predição de ECCAM em pacientes com infarto agudo do miocárdico com supradesnivelamento do segmento ST (IAMCSST) submetidos à ICP primária. Métodos: Foram analisados 311 pacientes consecutivos com IAMCSST submetidos a ICP primária entre abril/2011 e dezembro/2015. As áreas sob a curva característica de operação do receptor (ROC) foram calculadas para avaliar a habilidade desses escores em predizer ECCAM. O nível de significância adotado em todos os testes foi de 5%. Resultados: Os pacientes apresentaram idade média de 60,2 ± 12,0 anos, 35,4% eram do sexo feminino e 22,5% eram diabéticos. A ocorrência de ECCAM foi observada em 23,8% dos participantes. A área sob a curva ROC foi 0,586 (p = 0,028) para ACEF, 0,616 (p = 0,003) para SS, 0,623 (p = 0,002) para ACEF Mod e 0,658 (p < 0,001) para CSS. Na análise multivariada, apenas SS (p = 0,011) e CSS (p = 0,002) foram preditores independentes de ECCAM. Conclusões: SS e CSS elevados foram preditores independentes de ECCAM. Em nossa coorte de pacientes com IAMCSST submetidos à ICP primária, o SS calculado à cineangiocoronariografia inicial mostrou-se uma ferramenta útil para predizer ECCAM

Background: Different scores based on anatomical and/or clinical features have been developed for risk stratification of patients undergoing percutaneous coronary intervention (PCI). Studies comparing the ability of these different models in predicting major adverse cardiac and cerebrovascular events (MACCE) in patients submitted to primary PCI are limited. Objectives: The aim of this study was to compare the ability of the scores SYNTAX (SS), Clinical SYNTAX (CSS), age, creatinine and ACEF, and modified ACEF (ACEF Mod ) to predict MACCE in patients with ST-elevation myocardial infarction (STEMI) submitted to primary PCI. Methods: We analyzed 311 consecutive patients with STEMI submitted to primary PCI between April/2011 and December/2015. The area under the ROC curve was calculated to evaluate the ability of these scores in predicting MACCE. P-values were considered significant at < 0.05. Results: Mean age of the patients was 60.2 ± 12.0 years, 35.4% were females, and 22.5% had diabetes. MACCE occurred in 23.8% of the patients. The area under the ROC curve was 0.586 (p = 0.028) for ACEF, 0.616 (p = 0.003) for SS, 0.623 (p = 0.002) for ACEF Mod , and 0.658 (p < 0.001) for CSS. In multivariate analysis, only high SS (p = 0.011) and CSS (p = 0.002) were independent predictors of MACCE. Conclusions: High SS and CSS were independent predictors of MACCE. In our cohort of STEMI patients undergoing primary PCI, pure anatomical SS calculated at the baseline coronary angiography was a useful tool to predict MACCE

On- vs. off-hours admission of patients with ST-elevation acute myocardial infarction undergoing percutaneous coronary interventions: data from a tertiary university Brazilian hospital

Introduction: Early reperfusion therapy is crucial in patients with ST-elevation myocardial infarction (STEMI). Off-hours hospital presentation may increase the time from pain to coronary reperfusion, and it may be responsible for increased cardiovascular outcomes. The aim of this study was to compare the effect of different times of presentation (on- and off-hours) on early mortality and major cardiovascular outcomes in patients with STEMI who underwent primary percutaneous coronary intervention (PCI). Methods: We have included consecutive patients with STEMI who underwent primary PCI between April 2011 and November 2016 in a tertiary university hospital in southern Brazil. Patients were divided into on- and off-hours admission. In-hospital and 30-day outcomes were evaluated. Results: A total of 301 patients (57.4%) were admitted during off-hours, and 223 (42.5%) during on-hours. Baseline characteristics were well balanced between the two groups. Median door-to-balloon time was higher in the off-hours group than in the on-hours group: 75 min (IQR 60-95) vs. 60 min (IQR 50-73.7) respectively (p < 0.001). In-hospital mortality was similar between groups (odds ratio [OR] = 0.56; 95% confidence interval [95%CI] 0.31-1.03; p = 0.06) and at 30-day follow-up (OR = 0.2; 95%CI 0.02-1.72 p = 0.14). In the matched cohort, no difference was found in the rates of in-hospital mortality (OR = 2.0; 95%CI 0.75-5.32; p = 0.16) and 30-day MACE (OR= 0.9; 95%CI 0.49-1.66; p = 0.75). Conclusions: In our center with PCI available 24/7 - without in-house staff - we did not observe any difference in patient characteristics, management, and outcomes, although a significant longer door-to-balloon time was found in patients treated during night shifts. Our results are consistent with those of other trials.

Efetividade da Terapia Medicamentosa e dos Procedimentos de Revascularização como Estratégia Inicial na Doença Arterial Coronariana Estável: Estudo de Coorte / Effectiveness of Medical and Revascularization Procedures as the Initial Strategy in Stable Coronary Artery Disease: A Cohort Study

Fundamento: A cirurgia de revascularização miocárdica (CRM) e a intervenção coronária percutânea (ICP) são estratégias amplamente utilizadas no manejo da doença arterial coronariana (DAC) estável. Objetivo: Avaliar o prognóstico de pacientes com DAC estável inicialmente tratada com terapia médica (TM), em comparação com os pacientes submetidos a procedimentos de revascularização. Métodos: Estudo prospectivo de coorte com 560 pacientes ambulatoriais de um hospital terciário com seguimento médio de 5 anos. Os pacientes foram classificados nos grupos TM (n = 288), ICP (n = 159) e CRM (n = 113) de acordo com sua estratégia inicial de tratamento. Os desfechos primários foram mortalidade global e eventos combinados de morte, síndrome coronária aguda e AVC. Resultados: Durante o seguimento, as taxas de mortalidade foram de 11,1% em TM, 11,9% em ICP e 15,9% em pacientes submetidos à CRM, sem diferença estatística (Hazard Ratio [HR] para ICP, 1,05; Intervalo de Confiança de 95% [IC95%], 0,59 a 1,84; e HR para CRM, 1,20; IC95%, 0,68 a 2,15). Os desfechos combinados ocorreram com maior frequência entre os pacientes inicialmente submetidos à ICP em relação à TM (HR 1,50, IC 95% 1,05 a 2,14) e não diferiram entre TM e CRM (HR 1,24, IC95% 0,84 a 1,83). Entre os pacientes com diabetes (n = 198), a ICP foi a única estratégia terapêutica preditiva de desfechos combinados (HR 2,14; IC 95%: 1,25 a 3,63). Conclusão: Neste estudo observacional de doença arterial coronariana estável, não houve diferença na mortalidade global entre as estratégias iniciais de terapia médico ou de cirurgia de revascularização. Os pacientes inicialmente tratados com ICP tiveram maior chance de desenvolver eventos cardiovasculares maiores combinados

Background: Coronary artery bypass grafting surgery (CABG) and percutaneous coronary intervention (PCI) are widely-used strategies in the management of stable coronary artery disease (CAD). Objective: To evaluate the prognosis of patients with stable CAD initially treated by medical therapy (MT), compared to the patients who were submitted to revascularization procedures. Methods: We conducted a prospective cohort study of 560 patients from an outpatient clinic in a tertiary hospital, with a mean follow-up of 5 years. Patients were classified into MT (n = 288), PCI (n = 159) and CABG (n=113) groups according to their initial treatment strategy. Primary endpoints were overall mortality and combined events of death, acute coronary syndrome, and stroke. Results: During follow-up, death rates were 11.1% in MT, 11.9% in PCI and 15.9% in CABG patients, with no statistical difference (hazard ratio [HR] for PCI, 1.05; 95% confidence interval [95%CI], 0.59 to 1.84; and HR for CABG, 1.20; 95% CI: 0.68 to 2.15). Combined outcomes occurred more often among patients initially submitted to PCI compared to MT (HR 1.50, 95% CI 1.05 to 2.14), and did not differ between MT and CABG patients (HR 1.24, 95% CI 0.84 to 1.83). Among patients with diabetes (n=198), PCI was the only therapeutic strategy predictive of combined outcomes (HR 2.14; 95% CI 1.25 to 3.63). Conclusion: In this observational study of stable coronary artery disease, there was no difference in overall mortality between initial medical therapy or revascularization surgery strategies. Patients initially treated with PCI had greater chance to develop combined major cardiovascular events

Giant thrombus entrapped by a patent foramen ovale in a patient with polycystic kidney disease

Polycystic kidney disease (PKD) is the most common genetic cause of chronic kidney disease (CKD). The most common cause of death in patients with this condition is cardiovascular disease, mainly due to hypertension and its consequences. We report a case of a 42-year-old male patient with polycystic kidney disease who developed a giant thrombus entrapped by a patent foramen ovale after an acute myocardial infarction (AU)

Síndrome coronariana aguda como apresentação atípica do fenômeno de roubo subclávio / Acute coronary syndrome as an atypical presentation of the phenomenon of subclavian steal

Roubo coronariano da subclávia (RCS) é um fenômeno raro que ocorre em pacientes submetidos a cirurgia de revascularização miocárdica com enxerto de artéria torácica interna esquerda (ATIE) e que causa estenose da artéria subclávia ipsilateral e proximal à origem da ATIE. Relatamos o caso de um paciente masculino de 65 anos que apresentou quadro atípico de síndrome do RCS, manifestando-se como síndrome coronariana aguda no pós-operatório de cirurgia vascular (AU)

Coronary subclavian steal (CSS) is a rare phenomenon that occurs in patients undergoing coronary artery bypass graft surgery using the left internal thoracic artery (LITA) causing stenosis of the ipsilateral subclavian artery proximal to the origin of the LITA. We report the case of a 65-year-old male patient who presented with atypical CSS syndrome, manifesting as acute coronary syndrome after vascular surgery (AU)

Cateterismo cardíaco direito por acesso venoso antecubital guiado por ultrassonografia / Right heart catheterization through ultrasound-guided antecubital vein approach

Introdução: As complicações no cateterismo cardíaco direito estão quase sempre relacionadas ao local de acesso. As veias do antebraço podem ser um alvo para reduzir tais complicações durante o procedimento. No entanto, dados relativos à ampla aplicação desta técnica são escassos. Métodos: Série de casos que relata nossas primeiras experiências com o cateterismo cardíaco direito por acesso venoso antecubital. Resultados: Tentamos realizar o cateterismo cardíaco direito em 20 pacientes com abordagem antecubital em janeiro de 2016. A abordagem antecubital foi bem-sucedida em 19 casos (95,0%). Todos os acessos venosos foram obtidos guiados por ultrassonografia. Os cateterismos cardíacos direito e esquerdo foram realizados simultaneamente em 12 casos (60,0%). O cateterismo cardíaco esquerdo foi realizado através da artéria radial direita em 11 casos (91,7%), e da artéria braquial direita em 1 caso (8,3%). O acesso antecubital foi obtido pela veia basílica em 18 (94,7%) casos, e pela veia cefálica em 1 (5,3%) caso. Conclusões: O cateterismo cardíaco direito através das veias da prega antecubital parece ser viável e seguro. Outros estudos controlados são necessários para estabelecer o melhor local de acesso para realizar o cateterismo cardíaco direito

Background: Complications in right heart catheterization are almost all access-site related. Forearm veins may be a target to reduce access-site complications during the procedure. However, data regarding wide application of this technique is scarce. Methods: This is a case-series that reports our first experiences in right heart catheterization through the antecubital approach. Results: We attempted to perform right heart catheterization in 20 patients using antecubital approach on January 2016. The antecubital approach was successful in 19 (95.0%) cases. All venous access were obtained with ultrasound guidance. Simultaneous right and left heart catheterization was performed in 12 cases (60.0%). Left heart catheterization was performed through right radial artery in 11 cases (91.7%) and through the right brachial artery in 1 case (8.3%). Antecubital access was obtained through the basilic vein in 18 (94.7%) cases and through the cephalic vein in 1 (5.3%) case. Conclusions: Right heart catheterization through the antecubital fossa veins appears to be feasible and safe. Further controlled studies are required to establish the best access site to perform right heart catheterization

Desfechos cardiovasculares em pacientes tratados com intervenção percutânea coronária primária em hospital geral terciário / Cardiovascular outcomes in patients treated with primary percutaneous coronary intervention in a general tertiary hospital

Introdução: Existem poucos dados nacionais a respeito dos resultados da intervenção coronária percutânea (ICP) primária, e os registros são uma ótima ferramenta para a avaliação do perfil dos pacientes e dos desfechos pós-procedimento. O objetivo deste estudo foi descrever o perfil dos pacientes com ICP primária em um hospital geral terciário, bem como avaliar os desfechos cardiovasculares hospitalares e em 30 dias. Métodos: Foram incluídos todos os pacientes submetidos à ICP primária entre 2012 a 2015. Trata-se de um registro prospectivo, no qual os desfechos clínicos analisados foram a ocorrência de morte, infarto ou acidente vascular cerebral, e eventos cardiovasculares e cerebrovasculares maiores (ECCAM). Resultados: Foram incluídos 323 pacientes, com idade 60 ± 12 anos, sendo 66,7% do sexo masculino, 28,5% diabéticos. Na admissão, 13,5% dos pacientes apresentavam-se em Killip III/IV. O tempo dor-porta foi de 4,4 ± 2,5 horas e o tempo porta-balão foi 68,0 ± 34,0 minutos. A mortalidade hospitalar foi de 9,9%, e 18,3% dos pacientes apresentaram ECCAM em 30 dias. Conclusões: Os pacientes submetidos à ICP primária apresentaram taxas elevadas de ECCAM, que podem ser atribuídas à apresentação clínica mais grave e a um longo tempo de isquemia. Um atendimento mais rápido destes pacientes, variável modificável, demanda uma atenção imediata do sistema de saúde

Background: There are few national data on the results of primary percutaneous coronary intervention (PCI), and registries are a great tool for assessing patient profiles and post-procedure outcomes. The aim of this study was to describe the profile of patients with primary PCI in a general tertiary hospital, as well as to evaluate in-hospital and 30-day cardiovascular outcomes. Methods: The study included all patients submitted to primary PCI between 2012 and 2015. This was a prospective registry, in which the analyzed clinical outcomes were the occurrence of death, infarction, or stroke, and major cardiovascular and cerebrovascular events (MACCE). Results: The study included 323 patients, aged 60 ± 12 years, of whom 66.7% were males, 28.5% diabetics. At admission, 13.5% of the patients were classified as Killip class III/IV. The pain-to-door time was 4.4 ± 2.5 hours and the door-to-balloon time was 68.0 ± 34.0 minutes. Hospital mortality was 9.9%, and 18.3% of the patients presented MACCE in 30 days. Conclusions: Patients submitted to primary PCI had high rates of MACCE, which can be attributed to the more severe clinical presentation and to a long time of ischemia. The faster treatment of these patients, a modifiable variable, demands immediate attention from the health system
