Time to twist: marker of systolic dysfunction in Africans with hypertension
Maharaj N, Khandheria BK, Peters F, Libhaber E, Essop MR. Time to twist: marker of systolic dysfunction in Africans with hypertension. Eur Heart J Cardiovasc Imaging. 2013 Apr;14(4):358-65.
AIMS: Speckle-tracking echocardiography (STE) has emerged as a quantitative technique to assess left ventricular (LV) function via twist mechanics. Hypertension-associated changes in LV twist have not been previously evaluated in African patients with LV systolic dysfunction. This study evaluates LV twist dynamics in hypertensive patients with a low ejection fraction (EF).
METHODS AND RESULTS: Forty-one hypertensive patients with EF
CONCLUSIONS: LV twist in patients with hypertension and EF ,45% is diminished. Apical rotation and net twist are good correlates for EF in hypertensive patients with EF ,45%.
