[National Re-survey of Arterial Hypertension (RENAHTA). Mexican consolidation of the cardiovascular risk factors. national follow-up cohort].

RENAHTA shows the impact of hypertension on the morbidity and mortality during the 3.1 +/- 1.5 years of follow-up in Mexico. It alerts us on the need to reinforce the strategies of attention and prevention of this crucial risk factor and of screening the dynamic nonlinear interaction between the main cardiovascular risk factors in Mexico. New hypotheses are proposed for the metabolic syndrome.
