Although AAS misuse is often driven by aesthetic and performance goals, accumulating evidence links chronic exposure to a range of cardiovascular complications, including cardiomyopathy, arrhythmias, and thromboembolic events. However, the contemporary burden and clinical characteristics of severe AAS-related cardiovascular disease are not well characterised.</span></span></span></span></span></span></p>

Cardiac complications were prespecified and identified through clinician documentation and hospital discharge coding in the electronic medical record. Owing to the limited sample size, analyses were primarily descriptive. Continuous variables were presented as medians with interquartile ranges, and categorical variables as counts and percentages. Incidence rates of cardiac complications among AAS users were calculated relative to total cardiac admissions during the study period.</span></span></span></span></span></span></p>

The median age was 29 years (IQR 25&ndash;33). The predominant cardiovascular complications were cardiomyopathy or heart failure (n = 15, 43%) and acute coronary syndromes (n = 12, 34%), followed by clinically significant arrhythmias (n = 5, 14%) and other causes (n = 3, 9%). Among patients with heart failure, the median left ventricular ejection fraction at admission was 31% (IQR 26&ndash;38), and the median NT-proBNP concentration was 4,250 pg/mL (IQR 2,400&ndash;7,600). Comorbid cardiovascular risk factors were frequent, mainly arterial hypertension (n = 13, 37%), dyslipidaemia (n = 19, 54%), and smoking (n = 10, 37%). The incidence of AAS-related cardiac complications was 0.42 per 1,000 hospital admissions, showing a progressive increase from 0.21 per 1,000 in 2020 to 0.65 per 1,000 in 2025 (p &lt; 0.01 for trend). The median length of hospital stay was 6 days (IQR 4&ndash;9), and in-hospital mortality was 3% (n = 1).</span></span></span></span></span></span></p>
