Determination of cardiac markers in canine age groups as predictors of cardiac failure

Abstract

Cardiovascular diseases are very common in canines, despite a thorough clinical examination and diagnostic tests such as radiography, electrocardiogram, echocardiography and blood pressure measurement, it is still difficult to estimate the severity and evolution of these pathologies. However, we must also point out that the heart generally shows certain substances called biomarkers, which help to determine its condition and its location, which is why this research was developed, with the sole objective of determining some cardiac biomarkers in canines. As predictors of cardiac involvement, in the present study three cardiac biomarkers were evaluated in thirty canines divided into three age groups grouped between 7 to 9 years (Group A); 9 to 12 years (Group B) and more than 12 years (Group C) respectively; resulting in group C presenting the highest proportion of positivity for the markers under study followed by groups A and B that match positive cases, likewise the Tnl biomarker was the most sensitive (26.6%), followed by TnC (20%). ) and BnP shows less sensitivity (16.6%). It is clear that, although cardiac biomarkers are considered an important aid in cardiological diagnosis, they cannot replace the information provided by a meticulous clinical examination and imaging aids such as echocardiography and radiography.
