Researchers at the University of Eastern Finland and Kuopio University Hospital have discovered several new biomarkers that are associated with incident heart failure. In a new study, several inflammatory biomarkers and cell energy metabolites were linked to an increased risk of incident heart failure.
The study used a random selection of 10,106 men participating in the Metabolic Syndrome in Men (METSIM) study, who at baseline did not have a diagnosis of incident heart failure. Elevated levels of inflammatory biomarkers and several biomarkers associated with heart metabolism, which were measured by NMR analysis, were associated with the development of incident heart failure in a follow-up that lasted for 8.8 years.
These new biomarkers included adiponectin, high‐sensitivity C‐reactive protein, the chronic inflammation biomarker GlycA, the amino acids alanine, and phenylalanine, as well as glycerol and pyruvate, which the heart muscle uses for energy. After adjustment for age, BMI, diabetes and statin medication, adiponectin, pyruvate, and urinary albumin excretion rate were associated with the development of incident heart failure.
In this study, the most common heart diseases underlying incident heart failure were elevated blood pressure, coronary artery disease, and especially previous myocardial infarction. More rarely, incident heart failure was caused by cardiomyopathy or valvular heart disease. Diabetes, systolic blood pressure, age, overweight, high insulin levels, declining kidney function, and microalbuminuria, which are well‐established risk factors for heart failure, were also associated with the development of incident heart failure.
The researchers used principal component analysis to classify incident heart failure associated risk factors and biomarkers into components that could possibly be linked to different courses of the disease. Four of these components were statistically significant for the development of incident heart failure. Three of the components contained a different inflammatory biomarker and one contained cell energy metabolites.
Earlier studies conducted in animal models have shown that disturbed metabolism of the heart muscle precedes, initiates, and maintains unfavorable changes in the heart. However, the newly published study is the first to show that biomarkers of energy metabolism predict the development of incident heart failure in humans.
By measuring biomarkers indicative of heart failure, it could be possible to better identify people with an elevated risk of developing incident heart failure.
