Sex, Smoke, and the Silent Calcification of the Aortic Valve
A large population study of nearly 30,000 Swedes aged 50-64 has revealed that aortic valve calcification (AVC), a key precursor to aortic stenosis, is nearly twice as prevalent in men as in women. Using cardiac CT scans, researchers found AVC in 9% of men compared to 5% of women, with male sex being a strong independent risk factor. The analysis also identified lipoprotein(a), hyperlipidaemia, hypertension, and smoking as significant drivers of AVC in both sexes, while higher body mass index was linked to the condition only in men.
Why it might matter to you:
This research provides a clear, evidence-based profile of who is most at risk for developing a common and serious valvular heart disease. For clinical decision-making, it underscores the importance of screening for specific modifiable risk factors like smoking and lipoprotein(a) levels, especially in male patients. Understanding these population-level associations can sharpen preventive cardiology strategies and inform more targeted patient discussions about cardiovascular health.
