We read with great interest the article by Sciarretta et al1 on antihypertensive treatment and development of heart failure in hypertension. They performed the largest network meta-analysis in essential hypertension, to our knowledge, and showed that the use of diuretics and renin-angiotensin system inhibitors are the most effective first-line antihypertensive drug for preventing heart failure. In this meta-analysis, however, the search strategy and study selection are somewhat unclear.
