Abstract [en]

Objective: To compare blood pressure response and antihypertensive medication use visit-by-visit from baseline in patients receiving losartan-based or atenolol-based therapy in the LIFE study.

Research design: LIFE was a randomized, double-blind trial comparing losartan-based and atenolol-based treatment regimens on the primary composite endpoint of death, myocardial infarction (MI), or stroke in 9193 patients aged 55-80 years with hypertension and left ventricular hypertrophy. Systolic and diastolic, pulse, and mean arterial pressures, blood pressure responder rates, distribution of open-label anti hypertensive agents utilized, and the proportion of patients on randomized treatment were determined for each group at each clinic visit over a follow-up period of at least 4 years.

Results: Overall blood pressure reductions were comparable in the losartan-based and atenolol-based treatment groups. The mean reductions in sifting trough systolic and diastolic blood pressures from baseline to the end of follow-up (or last visit before a primary endpoint event) were 30.2/16.6 mmHg in the losartan group and 29.1/16.8 mmHg in the atenolol group. The time-averaged difference in overall mean arterial pressure was similar between groups. The proportion of patients on individual dose combinations varied visit by visit but was generally comparable between groups. During the entire study, 56% (2579/4605) of losartan-treated patients received at least one dose of the combination of losartan 100 mg plus hydrochlorothiazide 12.5 mg and 51 % of atenolol-treated patients received 100mg of atenolol plus hydrochlorothiazide 12.5 mg at some time during the study.

Conclusions: Differences in blood pressure or distribution of add-on medications between treatment groups were not evident in the LIFE trial and, thus, cannot account for the observed outcome difference in the primary endpoint of risk reduction of the composite of cardiovascular death, stroke and MI favoring losartan.
