Patients were classified as SVS (no symptoms with low natriuretic peptide), progressive valve syndrome (mild symptoms or mildly elevated natriuretic peptide), or acute valve syndrome (acute deterioration or markedly elevated natriuretic peptide or reduced left ventricular ejection fraction), and stratified by initial aortic valve replacement and conservative strategies. The primary outcome was a composite of death or heart failure hospitalization. Subgroup analyses further classified patients into 5 phenotypes: SVS, progressive valve signs without symptoms, progressive valve symptoms, acute valve signs without symptoms, and acute valve symptoms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      In the initial aortic valve replacement stratum, acute valve syndrome was associated with higher risk for the primary outcome compared with SVS (adjusted hazard ratio [HR], 2.34 [95% CI, 1.19\u20134.59];\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      =0.01), whereas progressive valve syndrome was not.
