Sensitivity and specificity of romhilt-estes score criteria for detecting left ventricular hypertrophy / Монголын Анагаах Ухаан

ABSTRACT

BackgroundLeft ventricular hypertrophy (LVH) is associated with a substantially increased risk of cardiac morbidity and mortality [1-4], so its detection is of major importance, especially for individuals with hypertension or other cardiovascular risk factors. There are many criteria for the diagnosis of left ventricular hypertrophy based on the electrocardiogram but specificity and sensitivity are different depending on age, sex, obesity and ethnicity.GoalThe present study was conducted to determine the sensitivity and specificity of Romhilt-Estes point score criteria of ECG for the assessment of left ventricular hypertrophy by comparing it with the gold standard of echocardiography.Materials and Methods154 clinically diagnosed patients with primary arterial hypertension were included in this study. ECG of the patients was recorded and Romhilt-Estes score criteria calculated. This was followed by echocardiography and left ventricular mass and left ventricular mass index was calculated.ResultsIt was found that Romhilt-Estes score criteria had a sensitivity of 34.9% and specificity of 96.7%. The positive predictive value was 97.73 %whereas negative predictive value was 27.27 %.ConclusionsSensitivity of the criterion Romhilt-Estes score criteria was relatively poor for the diagnosis of left ventricular hypertrophy in patients with arterial hypertension. But specificity of Romhilt-Estes score criteria was high.
