In-Hospital influenza vaccination to prevent cardiorespiratory events in the first 45 days after acute coronary syndrome: A prespecified analysis of the VIP-ACS trial.

BACKGROUND: Influenza vaccination prevents major cardiovascular events in individuals presenting a recent acute coronary syndrome (ACS), however the early effect of an in-hospital double-dose vaccination strategy remains uncertain. METHODS: The VIP-ACS was a randomized, pragmatic, multicenter, open-label trial with a blinded-adjudication endpoint. Patients with ACS ≤ 7 days of hospitalization were randomized to an in-hospital double-dose quadrivalent inactivated influenza vaccine (double-dose) or a standard-dose influenza vaccine at 30 days post-randomization. The primary endpoint was a hierarchical composite of death, myocardial infarction, stroke, hospitalization for unstable angina, hospitalization for heart failure, urgent coronary revascularization, and hospitalization for respiratory infections, analyzed with the win ratio (WR) method in short-term follow-up (45-days after randomization). RESULTS: The trial enrolled 1,801 patients (≥18 years old). Median participant age was 57 years, 70 % were male. There were no significant differences between groups on the primary hierarchical endpoint: there were 5.7 % wins in the double-dose in-hospital group and 5.5 % wins in the standard-dose delayed vaccination group (WR: 1.03; 95 % CI: 0.70---1.53; P = 0.85). In a sensitivity analysis including COVID-19 infection in the hospitalizations for respiratory infections endpoint, overall results were maintained (WR: 1.03; 95 % CI 0.71---1.51; P = 0.87). Results were consistent for major cardiovascular events only (WR: 0.82; 95 % CI: 0.48---1.39; P = 0.46). No serious adverse events were observed. CONCLUSION: In patients with recent ACS, in-hospital double-dose influenza vaccination did not significantly reduce cardiorespiratory events at 45 days compared with standard-dose vaccination at 30 days post-randomization.

Association between Statin Therapy and Lower Incidence of Hyperglycemia in Patients Hospitalized with Acute Coronary Syndromes. / Associação entre Terapia com Estatinas e Menor Incidência de Hiperglicemia em Pacientes Internados com Síndromes Coronarianas Agudas.

BACKGROUND: Increased risk of new-onset diabetes with statins challenges the long-term safety of this drug class. However, few reports have analyzed this issue during acute coronary syndromes (ACS). OBJECTIVE: To explore the association between early initiation of statin therapy and blood glucose levels in patients admitted with ACS. METHODS: This was a retrospective analysis of patients hospitalized with ACS. Statin-naïve patients were included and divided according to their use or not of statins within the first 24 hours of hospitalization. The primary endpoint was incidence of in-hospital hyperglycemia (defined as peak blood glucose > 200 mg/dL). Multivariable linear and logistic regression models were used to adjust for confounders, and a propensity-score matching model was developed to further compare both groups of interest. A p-value of less than 0.05 was considered statistically significant. RESULTS: A total of 2,357 patients were included, 1,704 of them allocated in the statin group and 653 in the non-statin group. After adjustments, statin use in the first 24 hours was associated with a lower incidence of in-hospital hyperglycemia (adjusted OR=0.61, 95% CI 0.46-0.80; p < 0.001) and lower need for insulin therapy (adjusted OR = 0.56, 95% CI 0.41-0.76; p < 0.001). These associations remained similar in the propensity-score matching models, as well as after several sensitivity analyses, such as after excluding patients who developed cardiogenic shock, severe infection or who died during index-hospitalization. CONCLUSIONS: Among statin-naïve patients admitted with ACS, early statin therapy was independently associated with lower incidence of in-hospital hyperglycemia.

FUNDAMENTO: O maior risco de se desenvolver diabetes com o uso de estatinas é um desafio para a segurança do uso dessa classe de medicamentos em longo prazo. No entanto, poucos estudos analisaram essa questão durante síndromes coronarianas agudas (SCA). OBJETIVOS: Investigar a associação entre início precoce da terapia com estatina e níveis de glicemia em pacientes admitidos com SCA. MÉTODOS: Este foi um estudo retrospectivo de pacientes hospitalizados por SCA. Pacientes que nunca haviam usado estatinas foram incluídos e divididos segundo uso ou não de estatina nas primeiras 24 horas de internação. O desfecho primário foi a incidência de hiperglicemia na internação (definida como pico de glicemia > 200mg/dL). Modelos de regressão logística e modelos lineares multivariados foram usados para ajuste quanto a fatores de confusão e um modelo de pareamento por escore de propensão foi desenvolvido para comparações entre os dois grupos de interesses. Um valor de p menor que 0,05 foi considerado estatisticamente significativo. RESULTADOS: Um total de 2357 pacientes foram incluídos, 1704 deles alocados no grupo que receberam estatinas e 653 no grupo que não receberam estatinas nas primeiras 24 horas de internação. Após os ajustes, uso de estatina nas primeiras 24 horas foi associado com uma menor incidência de hiperglicemia durante a internação (OR ajustado = 0,61, IC95% 0,46-0,80; p < 0,001) e menor necessidade de uso de insulina (OR ajustado = 0,56, IC 95% 0,41-0,76; p < 0,001). Essas associações mantiveram-se similares nos modelos de pareamento por escore de propensão, bem como após análises de sensibilidade, como exclusão de pacientes que desenvolveram choque cardiogênico, infecção grave ou pacientes que foram a óbito durante a internação hospitalar. CONCLUSÕES: Entre os pacientes internados com SCA que não receberam estatinas previamente, a terapia precoce com estatina associou-se independentemente com menor incidência de hiperglicemia durante a internação.

Factors associated with actively working in the very long-term following acute coronary syndrome.

OBJECTIVES: Returning to work after an episode of acute coronary syndrome (ACS) is challenging for many patients, and has both personal and social impacts. There are limited data regarding the working status in the very long-term after ACS. METHODS: We retrospectively analyzed 1,632 patients who were working prior to hospitalization for ACS in a quaternary hospital and were followed-up for up to 17 years. Adjusted models were developed to analyze the variables independently associated with actively working at the last contact, and a prognostic predictive index for not working at follow-up was developed. RESULTS: The following variables were significantly and independently associated with actively working at the last contact: age>median (hazard-ratio [HR], 0.76, p<0.001); male sex (HR, 1.52, p<0.001); government health insurance (HR, 1.36, p<0.001); history of angina (HR, 0.69, p<0.001) or myocardial infarction (MI) (HR, 0.76, p=0.005); smoking (HR, 0.81, p=0.015); ST-elevation MI (HR, 0.81, p=0.021); anterior-wall MI (HR, 0.75, p=0.001); non-primary percutaneous coronary intervention (PCI) (HR, 0.77, p=0.002); fibrinolysis (HR, 0.61, p<0.001); cardiogenic shock (HR, 0.60, p=0.023); statin (HR, 3.01, p<0.001), beta-blocker (HR, 1.26, p=0.020), angiotensin-converting enzyme (ACE) inhibitor/angiotensin II receptor blocker (ARB) (HR, 1.37, p=0.001) at hospital discharge; and MI at follow-up (HR, 0.72, p=0.001). The probability of not working at the last contact ranged from 24.2% for patients with no variables, up to 80% for patients with six or more variables. CONCLUSIONS: In patients discharged after ACS, prior and in-hospital clinical variables, as well as the quality of care at discharge, have a great impact on the long-term probability of actively working.

The Use of Oral Beta-Blockers and Clinical Outcomes in Patients with Non-ST-Segment Elevation Acute Coronary Syndromes: a Long-Term Follow-Up Study.

BACKGROUND: The role of beta-blockers in patients with acute coronary syndromes is mainly derived from studies including patients with ST-segment elevation myocardial infarction. Little is known about the use of beta-blockers and associated long-term clinical outcomes in patients with non-ST-elevation acute coronary syndromes (NSTEACS). METHODS: We analyzed short- and long-term clinical outcomes of 2921 patients with NSTEACS using or not oral beta-blockers in the first 24 h of the acute coronary syndromes (ACS) presentation. The association between beta-blocker use and mortality was assessed using a propensity score adjusted analysis (N = 1378). RESULTS: Patients starting oral beta-blockers in the first 24 h of hospitalization, compared with patients who did not, had lower rates of in-hospital mortality (OR = 0.52, 95% CI 0.33 to 0.74, P = 0.002) and higher mean survival times in the long-term follow-up (11.86±0.4 years vs. 9.92±0.39 years, P < 0.001). CONCLUSION: The use of beta-blockers in the first 24 h of patients presenting with NSTEACS was associated with better in-hospital and long-term mortality outcomes.
