Short- and Midterm Adherence to Platelet P2Y12 Receptor Inhibitors After Percutaneous Coronary Intervention With Drug-Eluting Stents.

INTRODUCTION/OBJECTIVES: In patients who have undergone recent percutaneous coronary intervention (PCI), poor adhesion to antiplatelet agents may increase the risk of stent thrombosis and death. We aimed to investigate the adherence to different P2Y12 receptor inhibitors after PCI with drug-eluting stent in stable and unstable patients and to evaluate the factors associated with low adherence. METHOD: In a prospective study conducted between 2014 and 2018, the 8-item Morisky scale was applied at 30 days and 6 months post-PCI to measure P2Y12 receptor inhibitors adherence. Also, we describe the characteristics of patients using different platelet receptor P2Y12 inhibitors. Regression models were used to identify predictors of poor adherence. RESULTS: A total of 214 patients were included (65 ± 12 years, 81% man, 61% acute coronary syndromes). Patients in the clopidogrel group were older than those in the prasugrel (68 ± 12 vs 59 ± 11 years, P < .01, respectively) or ticagrelor group (68 ± 12 vs 62 ± 12 years, P < .01). Patients with low/moderate adherence at 30 days and 6 months represented, respectively, 19.8% and 27.5% of our sample. Current smokers and preexisting cardiovascular disease at presentation were associated with lower adherence at 30 days. CONCLUSIONS: We found substantial rates of moderate and low adherence to P2Y12 receptor inhibitors early after PCI. Current smokers and preexisting cardiovascular disease at presentation were associated with a lower likelihood of adherence. These results highlight the need of monitoring adherence to medical treatment after PCI.

Persistent Depressive Symptoms are Independent Predictors of Low-Grade Inflammation Onset Among Healthy Individuals / Sintomas Depressivos Persistentes são Preditores Independentes de Início de Inflamação de Baixo Grau em Indivíduos Saudáveis

Abstract Background: Depressive symptoms are independently associated with an increased risk of cardiovascular disease (CVD) among individuals with non-diagnosed CVD. The mechanisms underlying this association, however, remain unclear. Inflammation has been indicated as a possible mechanistic link between depression and CVD. Objectives: This study evaluated the association between persistent depressive symptoms and the onset of low-grade inflammation. Methods: From a database of 1,508 young (mean age: 41 years) individuals with no CVD diagnosis who underwent at least two routine health evaluations, 134 had persistent depressive symptoms (Beck Depression Inventory - BDI ≥ 10, BDI+) and 1,374 had negative symptoms at both time points (BDI-). All participants had been submitted to repeated clinical and laboratory evaluations at a regular follow-up with an average of 26 months from baseline. Low-grade inflammation was defined as plasma high-sensitivity C-Reactive Protein (CRP) concentrations > 3 mg/L. The outcome was the incidence of low-grade inflammation evaluated by the time of the second clinical evaluation. Results: The incidence of low-grade inflammation was more frequently observed in the BDI+ group compared to the BDI- group (20.9% vs. 11.4%; p = 0.001). After adjusting for sex, age, waist circumference, body mass index, levels of physical activity, smoking, and prevalence of metabolic syndrome, persistent depressive symptoms remained an independent predictor of low-grade inflammation onset (OR = 1.76; 95% CI: 1.03-3.02; p = 0.04). Conclusions: Persistent depressive symptoms were independently associated with low-grade inflammation onset among healthy individuals.

Resumo Fundamento: Sintomas depressivos estão associados de forma independente ao risco aumentado de doença cardiovascular (DCV) em indivíduos com DCV não diagnosticada. Os mecanismos subjacentes a essa associação, entretanto, não estão claros. Inflamação tem sido indicada como um possível elo mecanicista entre depressão e DCV. Objetivos: Este estudo avaliou a associação entre sintomas depressivos persistentes e o início de inflamação de baixo grau. Métodos: De um banco de dados de 1.508 indivíduos jovens (idade média: 41 anos) sem diagnóstico de DCV submetidos a pelo menos duas avaliações de saúde de rotina, 134 tinham sintomas depressivos persistentes (Inventário de Depressão de Beck - BDI ≥10, BDI+) e 1.374 não apresentavam sintomas em nenhuma das ocasiões (BDI-). Todos os participantes foram submetidos a repetidas avaliações clínicas e laboratoriais em seguimento regular, cuja média foi de 26 meses desde a condição basal. Definiu-se inflamação de baixo grau como concentração plasmática de proteína C reativa (PCR) ultrassensível > 3 mg/L. O desfecho foi a incidência de inflamação de baixo grau por ocasião da segunda avaliação clínica. Resultados: A incidência de inflamação de baixo grau foi maior no grupo BDI+ em comparação ao grupo BDI- (20,9% vs. 11,4%; p = 0,001). Após ajuste para sexo, idade, circunferência abdominal, índice de massa corporal, níveis de atividade física, tabagismo e prevalência de síndrome metabólica, os sintomas depressivos persistentes continuaram sendo um preditor independente de início de inflamação de baixo grau (OR = 1,76; IC 95%: 1,03-3,02; p = 0,04). Conclusões: Sintomas depressivos persistentes foram independentemente associados com início de inflamação de baixo grau em indivíduos saudáveis.

A time-series analysis of the relation between unemployment rate and hospital admission for acute myocardial infarction and stroke in Brazil over more than a decade.

BACKGROUND: The effect of socioeconomic stressors on the incidence of cardiovascular disease (CVD) is currently open to debate. Using time-series analysis, our study aimed to evaluate the relationship between unemployment rate and hospital admission for acute myocardial infarction (AMI) and stroke in Brazil over a recent 11-year span. METHODS AND RESULTS: Data on monthly hospital admissions for AMI and stroke from March 2002 to December 2013 were extracted from the Brazilian Public Health System Database. The monthly unemployment rate was obtained from the Brazilian Institute for Applied Economic Research, during the same period. The autoregressive integrated moving average (ARIMA) model was used to test the association of temporal series. Statistical significance was set at p<0.05. From March 2002 to December 2013, 778,263 admissions for AMI and 1,581,675 for stroke were recorded. During this time period, the unemployment rate decreased from 12.9% in 2002 to 4.3% in 2013, while admissions due to AMI and stroke increased. However, the adjusted ARIMA model showed a positive association between the unemployment rate and admissions for AMI but not for stroke (estimate coefficient=2.81±0.93; p=0.003 and estimate coefficient=2.40±4.34; p=0.58, respectively). CONCLUSIONS: From 2002 to 2013, hospital admissions for AMI and stroke increased, whereas the unemployment rate decreased. However, the adjusted ARIMA model showed a positive association between unemployment rate and admissions due to AMI but not for stroke. Further studies are warranted to validate our findings and to better explore the mechanisms by which socioeconomic stressors, such as unemployment, might impact on the incidence of CVD.
