Background

The relationship between physical activity and coronary artery calcification (CAC) was evaluated in different studies during the last years, although the results were conflicting.

Objective

The main objective of the present systematic review was to assess the association between different levels of physical activity and CAC score estimated by computed tomography (CT).

Methods

This systematic review was performed according to PRISMA guidelines. A literature search was performed to detect studies that evaluated the association between physical activity and CAC score. The levels of physical activity evaluated were those reported by the original publications. The CAC score was estimated by CT and was reported in Agatston units.

Results

Twenty six studies including 89,405 subjects were considered eligible for this research. The studies developed in the general population showed different results regarding the association between physical activity and CAC score: no association (7 studies), a positive association (4 studies), an inverse relationship (6 studies), a U-shaped relationship (2 studies), or different results depending on the subgroup evaluated (2 studies). In the largest studies, a positive association was observed. When we analyzed the studies that evaluated athletes, four studies showed a positive association between exercise intensity and CAC.

Conclusion

This systematic review showed disparate results regarding the association between physical activity and CAC score. The largest studies and most studies developed in athletes suggest that intense physical activity could be associated with high CAC score, although this hypothesis should be confirmed in future research.

The incorporation of a healthy diet, regular physical exercise and smoking cessation are the initial measures to reduce cardiovascular risk in patients with atherogenic dyslipidemia. In these patients, the nutritional quality of their diet should be improved, replacing foods with a greater atherogenic effect for others with a healthier effect. There is strong evidence that plant-based dietary patterns, low in saturated fatty acids, cholesterol and sodium, with a high content of fiber, potassium and unsaturated fatty acids, are beneficial and reduce the expression of cardiovascular risk factors. This document focuses on the role of nutrition in the prevention and treatment of atherogenic dyslipidemia, providing current evidence to serve as a tool for health professionals in its clinical management. To facilitate the reading of these recommendations, they are presented in a user-friendly table format, with a hierarchy of different levels of evidence.

Introduction and objectives

Cardiovascular diseases continue to lead the ranking of mortality in Spain. The implementation of geostatistical analysis techniques in the clinical laboratory are innovative tools that allow the design of new strategies in primary prevention of cardiovascular disease. The aim of this study was to study the prevalence and geolocation of severe dyslipidemia in the health areas under study in order to implement prevention strategies in primary care. A retrospective cohort study of low-density protein-bound cholesterol, triglyceride and lipoprotein (a) levels in the years 2019 and 2020 were carried out. In addition, a geostatistical analysis was performed including representation in choropleth maps and the detection of clustering clusters, using geographic information in zip code format included in the demographic data of each analytic.

Results

The analytical data included in the study were triglycerides (n = 365,384), low density protein-bound cholesterol (n = 289,594) and lipoprotein to lipoprotein (a) (n = 502). Areas with the highest and lowest percentage of cases were identified for the established cut-off points of LDL-C > 190 mg/dl and TG > 150 mg/dl. Two clustering clusters with statistical significance were detected for cLDL > 190 mg/dl and a total of 6 clusters for TG values > 150 mg/dl.

Conclusions

The detection of clusters, as well as the representation of choropleth maps, can be of great help in detecting geographic areas that require greater attention to intervene and improve cardiovascular risk.

Background and aims

Triglycerides are the initiators of the metabolic changes that lead to atherogenic dyslipidemia (AD). The APOA5 and APOA1 genes are involved in the response and metabolism of serum lipids and lipoproteins, where single nucleotide polymorphisms (SNP) rs662799 (promoter region) and rs5070 (intronic region) have been associated with the susceptibility to dyslipidemia. Until now, few studies evaluate the association of these polymorphisms with the presentation of hypertriglyceridemia and AD among Mexican children. Therefore, the objective was to determine the association between rs662799 and rs5070 with hypertriglyceridemia and AD in a pediatric population of southeastern Mexico.

Materials and methods

A case–control analysis was performed including 268 infants aged 2–16 years, anthropometric, clinical variables, and serum lipid profiles were analyzed. DNA was extracted from blood samples and genotyping of polymorphisms was executed with the TaqMan SNP genotyping assay. Allele and genotypic frequencies were calculated. For genetic association analysis, logistic regression models were fitted according to models of inheritance.

Results

The SNP rs662799 (C) was significantly associated with hypertriglyceridemia in the overdominant model (OR = 3.89, p = 0.001) and AD in the dominant model (OR = 4.01, p = 0.001). The SNP rs5070 (T) has a protective effect against hypertriglyceridemia in the additive risk model (OR = 0.68, p = 0.03).

Conclusion

Polymorphism rs662799 was significantly associated with cases of hypertriglyceridemia and AD in minors in southeastern Mexico. On the other hand, rs5070 polymorphism was not associated with cases of hypertriglyceridemia or AD.

Cardiovascular diseases (CVD) continue to be the main cause of death in our country. Adequate control of lipid metabolism disorders is a key challenge in cardiovascular prevention that is far from being achieved in real clinical practice. There is a great heterogeneity in the reports of lipid metabolism from Spanish clinical laboratories, which may contribute to its poor control. For this reason, a working group of the main scientific societies involved in the care of patients at vascular risk, has prepared this document with a consensus proposal on the determination of the basic lipid profile in cardiovascular prevention, recommendations for its realization and unification of criteria to incorporate the lipid control goals appropriate to the vascular risk of the patients in the laboratory reports.

Introduction

Chronic kidney disease (CKD) is a major health problem that contributes to the development of cardiovascular disorders such as heart failure and arteriosclerotic cardiovascular disease (ACVD). The aims of this study were to determine the prevalence of CKD and to assess its association with ACVD and cardiometabolic risk factors.

Methods

Cross-sectional observational study conducted in primary care setting. Population-based random sample: 6588 people between 18 and 102 years old (response rate: 66%). Crude and sex- and age-adjusted prevalence rates of CKD according to KDIGO were determined by assessing albuminuria and estimated glomerular filtration rate (eGFR) according to CKD-EPI, and their associations with cardiometabolic factors and ACVD were determined.

Results

The crude prevalence of CKD was 11.48% (95%CI: 10.72–12.27%), without significant difference between men (11.64% [95%CI: 10.49–12.86%]) and women (11.35% [95%CI: 10.34–12.41%]). The age- and sex-adjusted prevalence rate of CKD was 9.16% (men: 8.61%; women: 9.69%). The prevalence of low eGFR (<60 mL/min/1.73 m²) and albuminuria (≥30 mg/g) were 7.95% (95%CI: 7.30–8.61) and 5.98% (95%CI: 5.41–6.55), respectively.Hypertension, diabetes, prediabetes, increased waist-to-height ratio, heart failure, atrial fibrillation, and ACVD were independently associated with CKD (p < 0.001). Very high cardiovascular risk (CVR) according to SCORE was found in 77.51% (95%CI 74.54–80.49) of the population with CKD.

Conclusions

The adjusted prevalence of CKD was 9.2% (low eGFR: 8.0%; albuminuria: 6.0%). Most of the patients with CKD had very high CVR. Hypertension, diabetes, prediabetes, increased waist-to-height ratio and ACVD were independently associated with CKD.

Anti-PCSK9 monoclonal antibodies have reduced the risk of cardiovascular events in patients with atheroesclerosis cardiovascular disease. However, its use has not been described in hyperlipidemia associated with lorlatinib, a third-generation ALK tyrosin kinasa inhibitor approved as treatment for ALK-positive non-small cell lung cancer.
