Key result
Patients with hypertrophic cardiomyopathy had significantly increased left ventricular torsion compared to normal subjects (16.61 vs. 10.42, p=0.006), indicating subtle global systolic dysfunction.
Why the study?
Do advanced echocardiographic techniques (strain and torsion imaging) detect subtle left ventricular systolic dysfunction in adult patients with hypertrophic cardiomyopathy compared to normal controls?
Case-Control (n=36)
No

Absolute Event Rate: 16.61% vs 10.42%
p-value: p=0.006
Advanced echocardiographic techniques like strain and torsion imaging can detect subtle global systolic dysfunction in HCM patients who otherwise have normal traditional measures of systolic function.
No takes yet. Share an insight, caveat, or question.
May support torsion imaging to detect subclinical systolic dysfunction in HCM; hypothesis-generating for clinical utility.
Ranjan Shetty (2014) conducted a case-control in Hypertrophic Cardiomyopathy (n=36). Hypertrophic Cardiomyopathy vs. Healthy age-matched controls was evaluated on Left ventricular torsion (p=0.006). Patients with hypertrophic cardiomyopathy had significantly increased left ventricular torsion compared to normal subjects (16.61 vs. 10.42, p=0.006), indicating subtle global systolic dysfunction.
