Aims: To evaluate adherence to guideline-recommended drug therapies for primary and secondary cardiovascular prevention in a general Mediterranean population.
Subjects and methods: A cross-sectional study was conducted in a random sample of 2270 individuals (18-80 years) assigned to a health centre in Malaga (Spain). The appropriate use was analysed of statins, antithrombotics, beta-blockers, and angiotensin-converting enzyme inhibitors (ACEI) or angiotensin II type 1 receptor blockers (ARB), based on the criteria of the European Guidelines on Cardiovascular Prevention and the European Society of Hypertension-European Society of Cardiology.
Results: The prescription rate of statins, antithrombotics, beta-blockers, and ACEI/ARB was 7.8%, 5.1%, 3.3%, and 11%, respectively. The prescription of these drugs was inappropriate in 36.2%, 22.4%, 64.5%, and 0%, respectively. Overtreatment was more frequent in subjects with greater comorbidity or ≥ 2 vascular risk factors (p < 0.001). The percentage of individuals with prescription criteria but who did not receive the treatment was 19.5%, 4.7%, 2%, and 9.3%, respectively, increasing significantly with age, Charlson index, and the presence of ≥ 2 risk factors (p < 0.001). Only 11% of patients in secondary prevention received combination therapy with statins, antithrombotics, and ACEI/ARB. Patients with ischaemic heart disease, as compared to non-coronary vascular patients, more frequently received statins (56.1% vs. 25.6%; p = 0.0001) and antithrombotic drugs (66.7% vs. 56.4%; p = 0.02).
Conclusions: We detected a low adherence to existing pharmacological guidelines for the prevention of cardiovascular disease. A priority is to establish appropriate training and dissemination of cardiovascular prevention guidelines in the field of primary care.
