Atherosclerosis and Inflammation: Still a Long Way to Go

Ricardo Wang et al. Bruno Ramos Nascimento Fernando Carvalho Neuenschwander

Short Editorial related to the article: Role of Interleukin-18 and the Thrombus Precursor Protein in Coronary Artery Disease.

Ever since the initial works by Russell Ross on the importance of inflammation in the development, instability and rupture of the atherosclerotic plaque, which can result in acute coronary syndrome (ACS) or stroke, there has been an increase in publications on the activation pathways, expansion and perpetuation of the inflammatory process, which goes beyond the simple pathophysiological understanding, but mainly in finding specific treatment opportunities, aiming to reduce the so-called “residual risk” (cardiovascular events that occur in patients even when LDL cholesterol levels are within the therapeutic goals). It is estimated that approximately 100,000 new cases of acute myocardial infarction occur each year in Brazil, according to data from DATASUS. If we consider mortality rates of 5-10%, it is expected that approximately 90,000 patients per year will go to secondary prevention. If all patients receive a maximum statin dose, even so, approximately 40%2 will still have a residual risk of events, i.e., 36,000 patients will be at high risk for new cardiovascular events.

Role of Interleukin-18 and the Thrombus Precursor Protein in Coronary Artery Disease

Carlos Scherr et al. Denilson Campos de Albuquerque Roberto Pozzan Kezia Ataide … Talita Ludmila Fernanda Blanco Claudio Martins Mangia

Abstract

Background

Coronary failure is the leading cause of death worldwide and identifying patients at higher risk for coronary artery disease (CAD) is a challenge.

Objectives

To test the biomarkers interleukin 18 (IL-18) and thrombus precursor protein (TpP), involved in atherogenesis, to aid in the early assessment of CAD.

Methods

This was a cross-sectional cohort of 119 patients, stratified into three groups: Group I – acute coronary syndrome (39); Group II – chronic CAD (40) and Group III – control, without coronary lesion, but who might have risk factors for CAD (40). Statistical analysis was performed using the statistical program SPSS (Statistical Package for the Social Sciences) for Windows ,version 17.0 of 2008. The significance level was set at 0.05 or 5% (p <0.05), with a 95% confidence interval. Chi-square test (χ2), Analysis of variance (ANOVA), and Tukey’s test were used.

Results

The mean age was 60.36 ± 9.64 years; there was a prevalence of females in Group III (65.0% p = 0.002), but without statistical significance for the means of IL-18 and TpP. The means of IL-18 and TpP were increased in Group I when compared to the other groups; IL-18 = 1325.44 ± 1860.13 ng/dL, p = 0.002; TpP = 35.86 ± 28.36 µg / mL, p <0.001). When compared two-by-two, it was observed that Group I had higher mean IL-18 and TpP values than Group II (IL-18 = 353.81 ± 273.65 ng / dL; TpP = 25.66 ± 12, 17 µg / mL) and Group III (IL-18 = 633.25 ± 993.93 ng / dL; TpP = 18.00 ± 8.45 µg / mL).

Conclusion

There was an increase in these biomarkers in acute CAD, suggesting a relationship with the atherosclerotic plaque instability process, but not with the chronic phase. (Arq Bras Cardiol. 2020; 114(4):692-698)

Serum levels of interleukin-6 (Il-6), interleukin-18 (Il-18) and C-reactive protein (CRP) in patients with type-2 diabetes and acute coronary syndrome without ST-segment elevation

José Roberto Matos Souza et al. Romulo Tadeu Oliveira Maria Heloisa S. L. Blotta Otávio Rizzi Coelho

BACKGROUND: Atherosclerosis is an inflammatory disease, and serum levels of inflammatory markers such as interleukin 6 (IL-6), interleukin 18 (IL-18) and C-reactive protein (CRP) are used to evaluate patients with coronary artery disease. In patients with type-2 diabetes, atherosclerosis is related to a larger number of events such as myocardial infarction and death, when compared with patients without diabetes. OBJECTIVE: To evaluate the inflammatory response in patients with diabetes and acute events of coronary instability. METHODS: Two groups of patients were primarily selected. The first group was comprised of diabetic outpatients with stable angina (D-CCS) and presence of coronary artery disease on coronary angiography (n=36). The second group was comprised of diabetic patients seen in the emergency room with acute coronary syndrome (D-ACS) without ST-segment elevation (n=38). Non-diabetic patients with ACS (n=22) and CCS (n=16) comprised the control group. Serum levels of CRP, IL-6 and IL-18 were determined using nephelometry (CRP) and ELISA (IL-6 and IL-18) techniques. RESULTS: Higher serum IL-6 levels were found in diabetic or non-diabetic patients with ACS than in the group with CCS. On the other hand, diabetic patients with ACS had higher CRP levels in comparison with the other groups. Serum IL-18 levels were not significantly different among the patients studied. CONCLUSION: our findings suggest a more intense inflammatory activity in patients with coronary instability. This inflammatory activity, as measured by CRP, seems to be even more intense in diabetic patients.
