Background: No studies have investigated the association between self-rated health (SRH) and high-sensitivity C-reactive protein (hs-CRP) levels in South Koreans. We explored this association and analyzed differences between sexes. Methods: Using cross-sectional data from the 2015-2017 Korea National Health and Nutrition Examination Survey, we analyzed the association between SRH and high hs-CRP levels (>1.0 mg/L) in 14,544 Koreans aged ≥19 years who responded to the SRH survey and had hs-CRP test results. Differences in sociodemographic factors were analyzed using Pearson's chi-square test for categorical variables or the Mann-Whitney U test for continuous variables. Multiple logistic regression analysis was used to measure the association between hs-CRP levels and SRH according to sex while adjusting for other possible confounders. Results: The percentage of having a very poor to poor SRH was higher in the high hs-CRP level group (22.4%) than in the low hs-CRP level group (17.66%). Among men, the risk of a high hs-CRP level increased with worse SRH (adjusted for confounders; P for trend <0.001). After adjusting for all confounders, including chronic diseases, men with a very poor SRH showed a higher odds ratio (OR) for high hs-CRP levels than those with a very good SRH (fully adjusted OR, 1.74; 95% con dence interval, 1.04-2.90). Signi cant correlations were absent among women. Conclusions: A poor SRH was correlated with low-grade in ammation (high hs-CRP level) among male Korean adults. The ndings could be useful for developing health improvement programs and in goal setting at a national scale. Background Self-rated health (SRH) is an index utilized worldwide to summarize how patients perceive their overall health status [1]. SRH is an independent predictor of mortality and disease morbidity, even after adjusting for demographic, sociological, and medical risk factors [2]. Despite criticisms that SRH is assessed based on a single question, it is known to be a strong predictor in both healthy and unhealthy individuals. SRH is not only a predictor of previously diagnosed disease but also a predictor of reactions associated with the progression of disease in the premorbid stage; it encapsulates recent or sporadic health issues that may be missed by one-time objective testing, and it also re ects behavioral and emotional factors [2, 3]. C-reactive protein (CRP) is produced by hepatocytes following acute tissue injury or infection. Though CRP levels are generally elevated in cases of severe in ammation, high-sensitivity CRP (hs-CRP) levels increase nonspeci cally in the event of in ammation in the body. In particular, hs-CRP is used as an indicator to assess the risk of cardiovascular disease (CVD), and several studies have suggested hs-CRP as a predictor of mortality. In assessing CVD risk, the American Heart Association (AHA) and Centers for Disease Control and Prevention (CDC) de ned hs-CRP levels of >3.0 mg/L as indicating high risk, 1.0-3.0 mg/L as indicating average risk, and <1.0 mg/L as indicating low risk...

Design of the Study: Historical Cohort. Objectives: This study aimed to verify which risk factors contribute to increase hs-cTnI in patients with Myocardial Infarcion with ST segment elevation, to ana-lyze which prognostic impacts it may have and to evaluate troponin levels in pa-tients that had previous acute myocardial infarction and assess how this com-pared to patients without previous history of an acute event. Methodology: It was assessed medical records of patients admitted in the Cor-onary Unit of the Hospital de Clínicas (HC-UFPR) in Curitiba, South of Brazil, diagnosed with ST segment elevation Myocardial Infarction and whose serum levels of high sensitivity troponin I (hs-cTnI) were collected at admission moment. The select data were: gender, age, high blood pressure, smoking, diabetes, previous myocardial infarction, dyslipidemia and serum levels of high sensitivity troponin I. For prognostic proposes, it was analysed intra-hospital death and ventricular function, based on left ventricular ejection fraction. Findings: Patients admitted with previous myocardial infarction had lower levels of hs-TnI. Gender, age, presence of high blood pressure, tabagism, diabetes and dyslipidemia didn’t reveal correlation with troponin values, allowing the in-ference that high sensitivity troponin values at first presentation of these patients have no direct relation to these variables. Regarding prognosis, levels of high sensitivity troponin could not be associated to mortality or ventricular malfunction. Conclusions: At admission, high-sensitivity troponin I levels were lower in pa-tients with prior myocardial infarction. Relevance: This work correlates the values of the high-sensitivity troponin of    patients with ST segment Elevation Myocardial Infarction to cardiovascular risks factors and to the prognosis of these patients. This approach is not found in cur-rent medical literature, whose works mainly relates to acute events.
