Baseline assessments, including transthoracic echocardiogram, blood sampling, and dual energy X-ray absorptiometry, were performed.

However, seven patients with AV PFV &lt;2 m\/s did not exhibit any progression of AS. There were significant variations in terms of bone mineral density, T-score values, and biomarkers associated with bone turnover (i.e., bone alkaline phosphatase, tartrate-resistance acid phosphatase-5b) among the enrolled patients, but none of these factors were found to be associated with the progression of AS. All patients exhibited low vitamin D status, with a median level of 16.1 ng\/mL (25<jats:sup>th<\/jats:sup> percentile, 9.7 ng\/mL; 75<jats:sup>th<\/jats:sup> percentile, 23 ng\/mL). The baseline levels of AV PFV values were negatively correlated with 25-hydroxyvitamin D levels, determined by univariate linear regression analysis (beta coefficient = -0.756, 95% confidence interval, -0.136 \u0336 -0.023, p = 0.011).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Our data suggest that low vitamin D status might be a potential risk factor for the progression of AS in osteoporosis patients undergoing treatment with anti-resorptive medicines.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>\n                           <jats:italic>Summary<\/jats:italic>\n                        <\/jats:title>\n                <jats:p>Elderly patients with osteoporosis patients exhibited a subset of aortic valve stenosis.
