Septal-free wall disproportion in inferior infarction: the echocardiographic differentiation from hypertrophic cardiomyopathy.

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Inferior myocardial infarction and hypertrophic cardiomyopathy (ASH/IHSS) (n=30). Intervention: Inferior myocardial infarction (IMI) vs. Asymmetric septal hypertrophy (ASH) or idiopathic hypertrophic subaortic stenosis (IHSS). Primary outcome: Echocardiographic differentiation (systolic thickness of LVFW, relative wall motions, VS/LVFW in systole, VS to systolic diameter ratio).

Key result

Inferior myocardial infarction can be distinguished from hypertrophic cardiomyopathy by evaluating absolute systolic thickness of the LVFW, relative wall motions, and systolic VS/LVFW ratio.

Why the study?

Does echocardiographic evaluation of systolic wall thickness and motion improve the differentiation of inferior myocardial infarction from hypertrophic cardiomyopathy in patients with septal-free wall disproportion?

Population

30 patients (10 with inferior myocardial infarction, 10 with asymmetric septal hypertrophy, and 10 with idiopathic hypertrophic subaortic stenosis) evaluated by echocardiography and angiography.

Exposure

Echocardiographic evaluation of ventricular septum (VS) and left ventricular free wall (LVFW) thickness, motion, and cavity dimensions

Comparator

Comparison between patients with IMI and patients with ASH or IHSS

Outcome

Echocardiographic features distinguishing IMI from ASH/IHSSsurrogate

Echocardiographic assessment of systolic wall thickness, relative wall motions, and cavity dimensions can reliably differentiate inferior myocardial infarction from hypertrophic cardiomyopathy in patients presenting with similar diastolic septal-free wall disproportion.

Stern et al. (1978) conducted a cross-sectional in Inferior myocardial infarction and hypertrophic cardiomyopathy (ASH/IHSS) (n=30). Inferior myocardial infarction (IMI) vs. Asymmetric septal hypertrophy (ASH) or idiopathic hypertrophic subaortic stenosis (IHSS) was evaluated on Echocardiographic differentiation (systolic thickness of LVFW, relative wall motions, VS/LVFW in systole, VS to systolic diameter ratio). Inferior myocardial infarction can be distinguished from hypertrophic cardiomyopathy by evaluating absolute systolic thickness of the LVFW, relative wall motions, and systolic VS/LVFW ratio.
