ABSTRACT

Objetivo: identificar a incidência, fatores de risco e desfechos associados ao infarto agudo do miocárdio sem obstrução de artérias coronárias (myocardial infarction with nonobstructive coronary arteries ­ MINOCA). Método: estudo de coorte prospectivo em prontuários clínicos num hospital terciário do extremo Sul catarinense. Foram incluídos pacientes diagnosticados com infarto agudo do miocárdico (IAM) submetidos a estudo hemodinâmico nos anos de 2017 e 2018. Resultados: ao analisar 445 prontuários, observou-se a ocorrência de MINOCA em 28 pacientes (6,3%). Comparando o grupo MINOCA com o grupo IAM obstrutivo, os pacientes do grupo MINOCA eram mais jovens, com média de 54 anos (DP ± 14; p=0,007), tinham menor incidência de tabagismo (2 versus 156, p<0,001), hipertensão arterial (10 versus 242; p=0,002), menor tempo médio (dias) de internação hospitalar (5,79 ± 3,05 versus 7,49 ± 5,20; p= 0,02) e menos admissões em unidade de tratamento intensivo (5 versus 212; p=0,002). Conclusão: a incidência de MINOCA estimada dentre o total de IAM no Sul de Santa Catarina foi de 6,3% [IC 95]. Os pacientes do grupo MINOCA tiveram menor prevalência de comorbidades, melhor evolução intra-hospitalar e melhor desfecho.


Objective: to identify the incidence, risk factors and outcomes associated with myocardial infarction with nonobstructive coronary arteries (MINOCA). Method: it is a with prospective cohort study data collection from medical records data. Patients with acute myocardial infarction (AMI) that went through hemodynamic study in 2017 and 2018 were included. Results: when analyzing 445 medical records, the occurrence of MINOCA was observed in 28 patients (6.3%). Comparing the MINOCA group with the obstructive AMI group, patients in the MINOCA group were younger, with a mean age of 54 years (SD ± 14; p=0.007), had a lower incidence of smoking (2 versus 156, p<0.001), hypertension (10 versus 242; p=0.002), shorter mean length of hospital stay (days) (5.79 ± 3.05 versus 7.49 ± 5.20; p= 0.02) and fewer admissions to intensive care unit (5 versus 212; p=0.002). Conclusion: the estimated incidence of MINOCA among the total number of AMI in southern Santa Catarina was 6.3% [CI 95]. Patients in the MINOCA group had a lower prevalence of comorbidities, better in-hospital evolution and better outcome.
