ABSTRACT:

OBJECTIVES:

To describe, according to the type of first-line antihypertensive monotherapy (FLAM) the persistence rate and the cumulative probability of its potential given up to the advantage of another antihypertensive class (rotation) in the following 3 years.

METHODS:

retrospective survey (to avoid any “survey effect” undertaken by 551 French cardiologists, in treated hypertensive patients. The survey described the FLAM, patients characteristics when FLAM was introduced, when given up in case of rotation and at the inclusion visit, as well as the dates of introduction, rotation and visit.

STATISTICAL ANALYSIS:

Kaplan Meier’s method, Cox model.

RESULTS:

One thousand nine hundred and fifty five patients (62 +/- 11 years, males 57%, diabetes 13%, coronary disease 11%, LVH 20%) were analysed. At the end of 2.1 +/- 0.7 years, 1407 patients (72%) continued the FLAM alone (N=738, 52%) or combined (N=669, 48%). Survival analysis shows i) that the probability of rotation is roughly constant over time whatever the FLAM ii) that the probability of rotation against time is different according to the FLAM (p<0.0001, log rank) and lesser with ARB. These results are confirmed by the multivariate analysis (Cox model adjusted on age, sex and comorbidities).
