Abstract:

Cardiovascular disease (CVD), especially heart failure (HF) as its common final pathway, is the leading cause of morbidity and mortality worldwide. Furthermore, oxidative and inflammatory processes represent fundamental underlying mechanisms for the development and progression of HF. Of interest, in recent years the development of markers with diagnostic and prognostic value for this pathology and other related CVD has been revalued. Therefore, the objective of the present study was to quantify and evaluate inflammatory markers such as ultrasensitive CRP, IL-6, TNF-α and Hsp70 in the serum of patients with heart failure (HF) and to compare them with healthy individuals, also correlating the values obtained with oxidative stress markers and nitric oxide bioavailability previously investigated in these patients, as well as with the coexistence or not of secondary pulmonary hypertension (SPH) associated with HF. The determination of these mediators was achieved with standardized, reproducible, accurate and affordable biochemical methods. The values ​​obtained for uCRP, IL-6 and TNF-α were in accordance with the pattern of oxidative markers previously found in these patients, thus exposing the coexistence of oxidative stress and inflammation during HF, but which is more exacerbated even when it is associated with SPH, which it finds would increase its value as a biomarker in this pathology. However, the found levels of Hsp70 were controversial. Therefore, additional studies are needed to assess in greater detail the importance of the relationship between serum Hsp70 expression and SPH-associated or non-SPH morbidity in HF.

Biomarkers, Obesity, and Cardiovascular Diseases

Obesity and overweight are among the major health problems in the world today. The excessive accumulation of fat in adipose tissue is accompanied by low‐grade inflamma‐ tion, adipokine secretion dysregulation, oxidative stress, and an alteration of the secretion of gut hormones and food intake related to peptides. This is related to the development of cardiovascular diseases, which have been in...

Novel biomarkers for cardiovascular risk prediction

Cardiovascular disease (CVD) is the leading cause of death and disability worldwide. The primary prevention of CVD is dependent upon the ability to identify high-risk individuals long before the development of overt events. This highlights the need for accurate risk stratification. An increasing number of novel biomarkers have been identified to predict cardiovascular events. Biomarkers play a ...

Metabolomic Profiling for Identification of Novel Potential Biomarkers in Cardiovascular Diseases

Metabolomics involves the identification and quantification of metabolites present in a biological system. Three different approaches can be used: metabolomic fingerprinting, metabolic profiling, and metabolic footprinting, in order to evaluate the clinical course of a disease, patient recovery, changes in response to surgical intervention or pharmacological treatment, as well as other associat...
