Which Treatment Strategy Is Preferred In The Octogenarians With Acute Coronary Syndrome?

Objectives: To compare the efficacy of invasive and conservative strategy in the management of octogenarians with acute coronary syndrome. METHODS: The retrospective study was conducted after approval from the ethics review committee of University of Health Sciences, Derince Training and Research Hospital, Turkey and comprised data from April 2020 to April 2021 related to octogenarian patients of either gender admitted to University of Health Sciences, Darica Farabi Training and Research Hospital, Turkey with acute coronary syndrome diagnosis. The data was divided into invasive group A and conservative group B. Data was analysed using SPSS 25. RESULTS: Of the 168 patients with median age 84(interquartile range: 81-86 years), there were 25(14.9%) in group A; 14(56%) males and 11(44%) females. There were 143(85.1%) patientsin group B; 70(49%) males and 73 (51%) females. Overall mortality was 111(66.1%); 11(44%) in group A, and 100(69.9%) in group B (p=0.012). Elevated alanine aminotransferase and invasive strategy were independent factors associated with mortality (p<0.05). CONCLUSIONS: The invasive strategy in the management of octogenarian patients presenting with acute coronary syndrome was found to be more efficient compared to the conservative strategy.

Frequência e Motivos para a não Administração e Suspensão de Medicamentos durante um Evento de Síndrome Coronariana Aguda. Estudo ERICO / Frequency and Reasons for Non-Administration and Suspension of Drugs During an Acute Coronary Syndrome Event. The ERICO Study

Resumo Fundamentos: Poucos estudos discutiram causas para o subtratamento medicamentoso na SCA. Objetivos: Avaliar a não-administração e suspensão de medicamentos durante o tratamento intra-hospitalar da SCA na Estratégia de Registro de Síndrome Coronariana Aguda (estudo ERICO). Métodos: Analisamos prontuários de 563 participantes ERICO para avaliar a frequência e motivos da não administração e/ou suspensão de medicamentos. Construímos modelos de regressão logística para avaliar se sexo, idade ≥65 anos, nível educacional ou subtipo de SCA estavam associados com (a) não administração de ≥1 medicamentos; e (b) não administração ou suspensão de ≥1 medicamentos. O nível de significância foi 5%. Resultados: A amostra é composta por 58,1% de homens e com idade mediana de 62 anos. Em 183 (32,5%) participantes ≥1 medicamentos não foram administrados e 288 (51,2%) apresentaram ≥1 medicamentos não administrados ou suspensos. As causas mais frequentes foram risco de sangramento (aspirina, clopidogrel e heparina), insuficiência cardíaca (betabloqueadores) e hipotensão (inibidores da enzima conversora da angiotensina e bloqueadores dos receptores da angiotensina). Indivíduos com idade ≥65 anos (razão de chances [RC]:1,51; intervalo de confiança de 95% [IC95%]:1,05-2,19) e com angina instável (RC:1,72; IC95%:1,07-2,75) tiveram maior chance de não-administração. Considerando apenas pacientes com infarto do miocárdio, idade ≥65 anos foi associada tanto à não administração quanto à não administração ou suspensão. Conclusões: A não administração ou suspensão de ≥1 medicamento não foi rara no estudo ERICO. Indivíduos com idade ≥65 anos ou com angina instável tiveram maior chance de não administração e podem ser subtratados nesse cenário.

Abstract Background: Few studies have discussed the reasons for pharmacological undertreatment of Acute Coronary Syndrome (ACS). Objectives: To determine the frequency and reasons for the non-administration and suspension of medications during in-hospital treatments of ACS in the Strategy of Registry of Acute Coronary Syndrome (ERICO) study. Methods: The present study analyzed the medical charts of the 563 participants in the ERICO study to evaluate the frequency and reasons for the non-administration and/or suspension of medications. Logistic regression models were built to analyze if sex, age ≥65 years of age, educational level, or ACS subtype were associated with (a) the non-administration of ≥1 medications; and (b) the non-administration or suspension of ≥1 medications. The significance level was set at 5%. Results: This study's sample included 58.1% males, with a median of 62 years of age. In 183 (32.5%) participants, ≥1 medications were not administered, while in 288 (51.2%), ≥1 medications were not administered or were suspended. The most common reasons were the risk of bleeding (aspirin, clopidogrel, and heparin), heart failure (beta blockers), and hypotension (angiotensin-converting enzyme inhibitors and angiotensin receptor blockers). Individuals aged ≥65 (odds ratio [OR]:1.51; 95% confidence interval [95% CI]:1.05-2.19) and those with unstable angina (OR:1.72; 95% CI:1.07-2.75) showed a higher probability for the non-administration of ≥1 medication. Considering only patients with myocardial infarction, being ≥65 years of age was associated with both the non-administration and the non-administration or suspension of ≥1 medication. Conclusions: Non-administration or suspension of ≥1 medication proved to be common in this ERICO study. Individuals of ≥65 years of age or with unstable angina showed a higher probability of the non-administration of ≥1 medication and may be undertreated in this scenario.
