Do speckle-tracking and tissue-Doppler stress echocardiography detect subclinical LV impairment in hypertensive patients with normal ejection fraction compared to healthy controls?
p-value: p=<0.001
Speckle-tracking and tissue-Doppler imaging during stress echocardiography can detect early subclinical left ventricular systolic impairment in hypertensive patients with normal ejection fraction.
Hensel et al. (2014) conducted a case-control in Arterial hypertension (n=92). Speckle-tracking echocardiography (STE) and tissue-Doppler imaging (TDI) vs. Healthy controls was evaluated on Global peak systolic LV circumferential strain (CS), longitudinal strain (LS), and longitudinal strain rate (SR) (p=<0.001). Speckle-tracking and tissue-Doppler imaging detected significantly reduced LV systolic strain and strain rate in hypertensive patients compared to healthy controls during exercise (P<0.001).
