Abstract
Aims To test the diagnostic potential of a hand-held ultrasound device for screening for left ventricular hypertrophy in a hypertensive population using a standard echocardiographic system as a reference.
Methods One hundred consecutive hypertensive patients were enrolled. An experienced investigator performed measurements of the thickness of the anterior septum and posterior wall using the parasternal 2D-long axis view and the end-diastolic dimension of the left ventricle with both imaging devices. Left ventricular hypertrophy was defined as an increase in left ventricular mass 
134g.m–2 for men and 110g.m–2 for women, when indexed for body surface area and 143g.m–1 for men and 102g.m–1 for women, when indexed for height.
Results Sixty-five men and 35 women were studied (age 60±11 years); mean duration of hypertension: 13±11 years; mean blood pressures: systolic 150±20mmHg and diastolic 89±11mmHg. The anterior septum and posterior wall were visualized in all patients with both imaging devices. The standard echocardiographic system identified left ventricular hypertrophy by body surface area in 18 (18%) patients and by height in 26 (26%) patients. The agreement between the standard echocardiographic system and the hand-held device for the assessment of left ventricular hypertrophy was 93%, kappa: 0·77 (left ventricular mass/body surface area) and 90%, kappa: 0·76 (left ventricular mass/height).
Conclusions We conclude that hand-held devices can be effectively applied for screening for left ventricular hypertrophy in hypertensive patients.
Key Words: Left ventricular hypertrophy, left ventricular mass, hand-held ultrasound device
