Changes over time in the prevention of recurrent coronary artery disease in everyday practice.

Introduction: Patients with coronary artery disease (CAD) are at high risk of recurrent cardiovascular events, and risk factor control is crucial in this population.

Objectives: The aim of the study was to compare the implementation of the European Society of Cardiology guidelines regarding prevention of recurrent CAD in 2011 to 2013 with 2016 to 2017.

Patients And Methods: The study included 5 hospitals with cardiology departments serving the city of Kraków and its surrounding districts. Consecutive patients with established CAD were interviewed 6 to 18 months after hospitalization in the years 2011 to 2013 and 2016 to 2017.

Results: We examined 616 patients in 2011 to 2013 and 388 in 2016 to 2017 (mean [SD] age, 64.7 [8.8] years vs 66.4 [8.4] years; P <0.01). After adjusting for covariates, the proportion of patients with high blood pressure decreased by 8.9% (95% CI, -15.6% to -2.1%) and the proportion of patients with high level of low‑ density lipoprotein cholesterol declined by 9.5% (95% CI, -16.7% to -2.2%) in 2016 to 2017 compared with 2011 to 2013, whereas the proportion of smoking patients (-0.2% [95% CI, -6% to 5.5%]) and those with high glucose levels (3.9% [95% CI, -2.2% to 10%]) and a body mass index of 25 kg/m2 or greater (3.8% [95% CI, -3.9% to 11.6%]) did not change. More patients were prescribed antiplatelets, β‑ blockers, angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, calcium antagonists, and anticoagulants in the second period.

Conclusions: We observed an increase in the proportion of patients with CAD who were prescribed cardiovascular drugs, and consequently a slight improvement in the control of their blood pressure and low‑ density lipoprotein cholesterol. No changes were found regarding other main risk factors.
