Abstract/OtherAbstract:
In hypertension, the presence of left ventricular hypertrophy (LVH) is associated with increased risk of both cardiovascular morbidity and mortality. To date, the electrocardiogram (ECG) remains the cornerstone of LVH diagnosis in clinical practice because it is universally available, technically easy to perform and highly specific. In the most recent European Society of Hypertension/European Society of Cardiology guidelines for the treatment of arterial hypertension, the Sokolow-Lyon voltage criterion was recommended as part of all routine assessment of subjects with hypertension. However, the use of the ECG in the diagnosis of LVH is somewhat limited by its poor sensitivity. In this review article, we discuss the individual strength and weaknesses of the commonly used ECG criteria in diagnosing LVH. In addition, we present the latest data on the prognostic significance of ECG LVH and the survival differences conferred in different genders. In view of the recent Losartan Intervention for Endpoint Reduction in Hypertension trial, the prognostic benefit of LVH regression will also be addressed. Finally, with the wider availability of echocardiography, the role of combining both modalities to improve risk stratification in hypertension is reviewed.
