Introduction Adherence to proposed lifestyle changes and prescribed medication in patients with stable coronary artery disease (SCAD) is poor. Objective We sought to investigate the influence of adjusting guideline proposed medications on relief of angina in a large group of patients with SCAD in Serbia. Methods The study included a total of 3,490 patients from 15 cardiology clinics with symptoms of stable angina and at least one of the following criteria: abnormal electrocardiogram (ECG), history of myocardial infarction (MI), positive stress test, significant coronary artery disease on coronary angiogram or previous revascularization. All the patients underwent comprehensive evaluation at initial visit and after two months. The relief of angina was study end-point defined as any reduction in Canadian Cardiology Society (CCS) class, number of angina attacks per week and/or number of tablets of short-acting nitrates per week. Results Most patients were included based on abnormal ECG (48.4%). At Visit 1, the average number of prescribed classes of medications to a single patient increased from 4.16 ± 1.29 to 4.63 ± 1.57 (p < 0.001). At the follow-up, the patients had significantly lower blood pressure (141 ± 19/85 ± 11 vs. 130 ± 12/80 ± 8 mmHg; p < 0.001) and most of them reported CCS class I (63.3%). The average weekly number of angina attacks was reduced from 2.82 ± 2.50 at Visit 1 to 1.72 0 ± 1.66 at Visit 2, as well as average weekly use of short-acting nitrates to treat these attacks (2.69 ± 2.53 to 1.74 ± 1.47 tablets; p < 0.001 for all). Conclusion Adjustment of prescribed medications to guideline recommendations in a large Serbian patient population with prevalent risk factors led to significant relief of angina.|
