[Twenty-year experience in strict versus non-strict control of arterial hypertension in a health center in Spain].

Introduction and Aims: During clinical trials effective reduction of blood pressure (BP) leads to a reduction in the incidence of cardiovascular (CV) morbimortality. Our main aim is to ascertain whether, under actual conditions of clinical practice, BP monitoring leads to a long-term reduction in CV events.
Patients and Methods: The study was performed on 164 patients with hypertension (HT) selected among patients who came to family medicine consultations because of HT. An analysis was performed between patients who presented clinical BP lower than 140/90mmHg and those that had higher levels. When patients entered the study, they were followed up until a CV event occurred or up to a maximum of 20 years, at which time follow up ended.
Results: Of the total of 164 patients, good control of BP was attained by 93 (56.7%), and 71 did not attain good control (42.2%). In the multivariate analysis, the only predictive variable for CV events was the lack of strict control of BP (HR: 2.93; 95% CI: 1.45-5.89; p=0.003), and the female sex was protective for CV events (HR: 0.37; 95% CI: 0.18-0.74; p=0.005).
Conclusions: The fundamental predictor variable of CV morbimortality in patients with HT is the lack of HT strict control; the women also had fewer CV complications.
