Why the study?
The prognostic utility of follow-up transthoracic echocardiography in patients with HCM was unclear, specifically whether changes in routine echocardiographic parameters are associated with cardiovascular outcomes.
Do progressive changes in echocardiographic parameters predict cardiovascular outcomes in patients with hypertrophic cardiomyopathy?
Do progressive changes in echocardiographic parameters predict cardiovascular outcomes in patients with hypertrophic cardiomyopathy?
Cross-sectional baseline echocardiographic parameters, particularly left atrial volume index, are superior to longitudinal changes in predicting cardiovascular events in patients with hypertrophic cardiomyopathy.
No takes yet. Share an insight, caveat, or question.
Baseline LAVI was associated with HCM outcomes; leaves open whether serial echo changes add prognostic value beyond baseline assessment.
