Compelling therapy of LVH: straight (and not-so-straight) inferences from evidence

We have read with interest the Korean Society of Hypertension guidelines for the management of hypertension and congratulate the Society for an extensive review of literature while drafting the guidelines. The guidelines indicate preferring ACE-I and CCB over diuretics in patients with left ventricle hypertrophy. However, in landmark head-to-head comparison trials, the thiazide-like diuretic chlorthalidone has been shown to be superior to ACE-I and CCB in decreasing left ventricle mass and preventing heart failure in hypertensive patients. Also, we put forth the paradoxical finding that mere regression of LVH may not always translate into reduction in risk of HF; and that the pleiotropic effects of chlorthalidone may be the explanation behind its beneficial action in HF.
