[Therapeutic exchange of angiotensin II receptor antagonists in patients hospitalised in a traumatology unit].

Objective: To analyse the proportion of patients whose blood pressure values have remained within the established therapeutic aim, so as to reduce cardiovascular risk following therapeutic exchange of angiotensin II receptor antagonists (AIIRA.)

Methods: Analytical, observational, prospective, longitudinal study with pre-post analysis. Patients undergoing AIIRA treatment who were not included in the hospital's pharmaco-therapeutic guide were included in the study over those who had undergone a normalised therapeutic exchange of AIIRA. Variable response: proportion of patients whose blood pressure levels (BP levels) remained within the established therapeutic aim for the prevention of cardiovascular accidents. Other variables: systolic and diastolic blood pressure values (SBP and DBP) in the month prior to hospitalisation and after therapeutic exchange, antihypertensive medication, comorbidities.

Results: 37 patients were included in the study. Following therapeutic exchange, 81.08 % maintained BP values within the range established by the European Society of Hypertension-European Society of Cardiology Committee. SBP difference: 4.82 (confidence interval [CI] 95 %: 1.09 to 10.74; p = 0.107); DBP difference: 0.15 (CI 95 %: 3.27 to 2.97; p = 0.924), and therefore not clinically significant.

Conclusions: The normalised procedure for therapeutic exchange of AIIRA is effective and safe for patients in terms of maintaining BP, which allows for adequate control of BP during the hospital stay.
