BackgroundThe association between high-sensitivity C-reactive protein and recurrent major adverse cardiovascular events (MACE) in patients with ST-elevation myocardial infarction who undergo primary percutaneous coronary intervention remains controversial.ObjectiveTo investigate the potential association between high-sensitivity C-reactive protein and an increased risk of MACE such as death, heart failure, reinfarction, and new revascularization in patients with ST-elevation myocardial infarction treated with primary percutaneous coronary intervention.MethodsThis prospective cohort study included 300 individuals aged >18 years who were diagnosed with ST-elevation myocardial infarction and underwent primary percutaneous coronary intervention at a tertiary health center. An instrument evaluating clinical variables and the Thrombolysis in Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) risk scores was used. High-sensitivity C-reactive protein was determined by nephelometry. The patients were followed-up during hospitalization and up to 30 days after infarction for the occurrence of MACE. Student's t, Mann-Whitney, chi-square, and logistic regression tests were used for statistical analyses. P values of ≤0.05 were considered statistically significant.ResultsThe mean age was 59.76 years, and 69.3% of patients were male. No statistically significant association was observed between high-sensitivity C-reactive protein and recurrent MACE (p = 0.11). However, high-sensitivity C-reactive protein was independently associated with 30-day mortality when adjusted for TIMI [odds ratio (OR), 1.27; 95% confidence interval (CI), 1.07-1.51; p = 0.005] and GRACE (OR, 1.26; 95% CI, 1.06-1.49; p = 0.007) risk scores.ConclusionAlthough high-sensitivity C-reactive protein was not predictive of combined major cardiovascular events within 30 days after ST-elevation myocardial infarction in patients who underwent primary angioplasty and stent implantation, it was an independent predictor of 30-day mortality.
65 anos, a interleucina 6 (IL-6), fator de necrose tumoral alfa (TNF α) e interleucina-10 (IL-10) têm se mostrado bons preditores de desfechos cardiovasculares. Em relação à proteína C-reativa (PCR), os dados são inconsistentes e ela parece ter menor poder como preditor em idosos, quando comparada aos indivíduos de meia-idade. Níveis de fibrinogênio parecem ser preditores de mortalidade, porém de uma forma não específica, ou seja, não apenas para mortalidade cardiovascular. Além disso, os marcadores inflamatórios também são indicadores de declínio funcional e mortalidade, independentemente da presença de doença cardiovascular. As evidências atuais são insuficientes para uso rotineiro dos marcadores inflamatórios, em idosos, já que existem poucos estudos nessa faixa etária, sendo a maioria deles de curta duração e com número reduzido de marcadores inflamatórios. A solicitação desses marcadores, de rotina, deve ser considerada individualmente.]]>
Background: The fasting plasma glucose (FPG) test is a predictor of complications after Acute Coronary Syndrome (ACS). However, its prognostic value is not yet fully established in different age groups.
