Whether patients with CAVS and high Lp(a) levels are at higher risk of valvular or cardiovascular events is unknown. The aim of this study is to determine whether higher Lp(a) levels are associated with valvular and cardiovascular outcomes in patients with CAVS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">We identified 1962 patients from the UK Biobank with an electronic health record or self\u2010reported CAVS diagnosis but who did not previously undergo aortic valve replacement (AVR) and had a minimal follow\u2010up time of 2.5\u2009years. Cox proportional hazard regression was used to evaluate the effect of Lp(a) on AVR, AVR or cardiac death, and valvular or cardiovascular events (AVR, cardiac death, myocardial infarction, stroke, heart failure, or coronary artery bypass grafting). The maximal follow\u2010up time was set to 5\u2009years. During the follow\u2010up, 198 patients underwent AVR, 260 had AVR or cardiac death, and 435 had at least 1 valvular or cardiovascular event. Patients with Lp(a) levels \u2265125 versus &lt;125\u2009nmol\/L were at higher risk of AVR (hazard ratio [HR], 1.58 [95% CI, 1.17\u20132.12]), AVR or cardiac death (HR, 1.43 [95% CI, 1.10\u20131.86]), and cardiovascular or valvular events (HR, 1.36 [95% CI, 1.11\u20131.68]). Point estimates were comparable in men versus women, younger versus older patients, and in patients with higher versus lower plasma C\u2010reactive protein levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p xml:lang=\"en\">In patients with CAVS, Lp(a) levels predicted a higher risk of valvular and cardiovascular outcomes.
