Notwithstanding the fact that the use of low-dose diuretics (overwhelmingly thiazides) in anti-hypertensive regimes has been associated with a risk reduction of the order of 0.51 (95% confidence interval 0.420.62) in the incidence of congestive heart failure,1 the absence of scrutiny of these drugs, to which the authors allude,2 has also included the failure to address the issue of whether the anti-hypertensive efficacy of long-acting loop diuretics such as torasemide might be comparable to that of thiazides, and whether, for both classes of drugs, the anti-hypertensive efficacy might be solely attributable to sustained natriuresis. A related issue is whether the protection that thiazides confer against hypertension-related heart failure might be rivalled, if not surpassed, by diuretics such as torasemide, which potentially possess cardioprotective properties by virtue of additional anti-aldosteronergic effects.3 The time is long overdue for these issues to be addressed, given the inescapable risk of hyponatraemia (including severe hyponatraemia) inherent in the use of thiazides,46 by virtue of their physiological actions on the renal tubule and collecting ducts.6
