Key result
Borderline hypertensive men with left ventricular hypertrophy had more supraventricular and ventricular ectopic beats than normotensive controls and those without hypertrophy.
Why the study?
Is borderline hypertension with left ventricular hypertrophy associated with increased cardiac arrhythmias compared to normotensive controls and borderline hypertensives without cardiac involvement?

Is borderline hypertension with left ventricular hypertrophy associated with increased cardiac arrhythmias compared to normotensive controls and borderline hypertensives without cardiac involvement?
Borderline hypertension with left ventricular hypertrophy is associated with a significantly higher frequency of supraventricular and ventricular ectopic beats, suggesting the need for echocardiographic risk stratification.

May support arrhythmia monitoring in borderline hypertension with LVH; hypothesis-generating and should not yet change practice.
Seventy-eight men with borderline hypertension according to the World Health Organization criteria underwent echocardiographic examination, followed by simultaneous ambulatory blood pressure and electrocardiographic monitorings for 24 h. The prevalence of echocardiographic left ventricular hypertrophy was 16.6% (13/78). Borderline hypertensives with left ventricular hypertrophy had more supraventricular (P less than .001) and ventricular ectopic beats (P less than .001) than normotensive controls and borderline hypertensives without cardiac involvement. Furthermore, ventricular ectopic activity was significantly related to left ventricular mass (r = 0.58, P less than .05) in borderline hypertensives showing echocardiographic evidence of left ventricular hypertrophy. Our findings suggest that noninvasive assessment of target organ status, including echocardiography, should be employed to optimize risk stratification in borderline hypertension.

Melina et al. (1992) conducted a cross-sectional in Borderline hypertension (n=78). Left ventricular hypertrophy vs. Normotensive controls and borderline hypertensives without left ventricular hypertrophy was evaluated on Supraventricular and ventricular ectopic beats (p=<0.001). Borderline hypertensive men with left ventricular hypertrophy had more supraventricular and ventricular ectopic beats than normotensive controls and those without hypertrophy.
