• Resumen

  • Asymptomatic hypertrophic cardiomyopathy (HCM) is common, affecting approximately 15% of apparently healthy cats and up to 25% of cats older than 9 years.

    Diagnosis should focus on identifying cats with high-risk HCM: those with increased risk of congestive heart failure or arterial thromboembolism.

    Murmur intensity does not correlate with the severity of HCM, and many high-risk cats have no audible murmur.

    The plasma biomarker pro-brain natriuretic peptide can be used as an initial screening test for high-risk HCM.

    A focused in-house echo to evaluate left atrial size provides important information: left atrial enlargement indicates high-risk HCM.
