Circulating bacterial DNA in cardiovascular disease

Frontiers in Cardiovascular Medicine

Conventional biomarkers, while effective for a number of patient groups, fail to provide personalized diagnosis and prognosis, necessitating the exploration of novel markers. Recent attention has turned to a subset of cfDNA, circulating bacterial DNA (cbDNA), derived from gut microbiota, as a potential biomarker.

Current and novel biomarkers in cardiogenic shock

European Journal of Heart Failure

A summary of current and novel biomarkers and their potential stages of release in cardiogenic shock. The diagram illustrates the proposed release of the biomarkers during the different stages of cardiogenic shock: progression from cardiac dysfunction/stress, through to inflammation and end-organ dysfunction.

Circulating miRNA-486 as a novel diagnostic biomarker for right ventricular remodeling

Frontiers in Cardiovascular Medicine

ObjectiveClinical practice currently faces a significant shortfall in specific biomarkers needed for diagnosing right ventricular (RV) remodeling in patients with pulmonary hypertension (PH). Among the 12 upregulated miRNAs, miRNA-486 exhibited highest elevation in PAB group and was supposed to be the candidate biomarker for RV modeling.

Circulating bone morphogenetic protein 10 as a novel marker of atrial stress and remodelling in heart failure

Heart BMJ

Background We evaluated the potential of circulating bone morphogenetic protein 10 (BMP10) as a biomarker for atrial stress and remodelling in patients with heart failure (HF), in comparison to N-terminal pro-B-type natriuretic peptide (NT-proBNP). We also assessed the predictive value of BMP10 for adverse clinical outcomes.

Circulating microRNAs as biomarkers of Chagas cardiomyopathy

Frontiers in Cardiovascular Medicine

Methods We carried out a case-control study to identify circulating miRNAs associated with CHCM. We performed a clinical, echocardiographic, and laboratory evaluation and profiled circulating miRNA in the serum samples. Results Differences between groups were observed in clinical variables and in the analysis of miRNAs.
