Early diagnosis of cardiac alterations in hypertensive heart disease is still challenging.
Since such patients might have depressed global LV systolic strain or strain rate when EF is still normal, speckle-tracking echocardiography (STE) and tissue-Doppler imaging (TDI) combined with stress echocardiography might improve early diagnosis of cardiac alterations.
In this prospective study standard 2D Doppler echocardiography, STE, and TDI were performed at rest and during bicycle exercise in 92 consecutive patients—46 hypertensive subjects with normal ejection fraction and 46 healthy controls.
STE and TDI were used to measure global peak systolic LV circumferential strain (CS), longitudinal strain (LS), and longitudinal strain rate (SR).
Mean arterial blood pressure was significantly higher in hypertensive patients at rest (100.8 mmHg SD 13.5 mmHg; P = 0.002 ) and during physical exercise testing (124.2 mmHg SD 13.4 mmHg; P = 0.003 ).
Hypertensive patients had significantly reduced values of systolic CS ( P = 0.001 ), LS ( P = 0.014 ), and SR ( P < 0.001 ) at rest as well as during physical exercise—CS ( P < 0.001 ), LS ( P < 0.001 ), and SR ( P < 0.001 ).
Using STE and TDI, reduced LV systolic strain and strain rate consistent with early cardiac alterations can be detected in patients with arterial hypertension.
These findings were evident at rest and markedly pronounced during exercise echocardiography.
