INTRODUCTION During the last decade, aortic stenosis (AS) has emerged as one of the most significant concerns in cardiovascular diseases. OBJECTIVES We aimed to characterize AS patients on the basis of data derived from a local registry. PATIENTS AND METHODS We used data from the SILesian CARDiovascular (SILCARD) registry, which was developed under the agreement between the Silesian Centre for Heart Diseases in Zabrze and the Silesian branch of the Polish National Health Fund in Katowice to conduct a comprehensive analysis of patients with cardiovascular diseases in Silesian Voivodeship. RESULTS A total of 15 158 patients hospitalized with a diagnosis of AS between 2006 and 2016 were included (mean [SD] age, 69.87 [11.97] years; male patients, 7644 [50.43%]). Heart failure was reported in 4187 patients (27.62%), and coronary artery disease, in 6217 (41.01%). During the first hospitalization, aortic valve intervention was performed in 2137 patients (14.10%), and during a 12‑‑ month follow‑‑ up, in 3416 (25.32%). During the first hospitalization, percutaneous coronary intervention (PCI) was performed in 666 patients (4.39%), and coronary artery bypass grafting (CABG), in 1071 (6.71%). At 12‑‑ month follow‑‑ up, PCI was reported in 560 patients (4.15%), and CABG, in 560 (4.15%). Between 2006 and 2016, 30‑‑ day mortality was 4.35% (659 patients) and remained stable throughout the study (5.4% in 2005 vs 4.0% in 2016, P = 0.28). The 1‑‑ year mortality was 15.88% (2142 patients) and increased from 14.3% in 2006 to 16% in 2015 (P = 0.07). CONCLUSIONS The SILCARD registry has revealed an increase in the number of AS diagnoses. AS has become one of the most critical issues among cardiovascular diseases in Silesian Voivodeship.
