APOB and mitral valve disorder: In the multivariate regression analysis, the discordance between LDL-C/apoB was independently associated with the use of LLT [OR 0.70 (95% CI 0.56–0.86), p < 0.001], age [OR 0.986 (95% CI 0.983–0.99), p < 0.001], male gender [OR 0.79 (95% CI 0.67–0.92), p = 0.003], DM [OR 0.60 (95% CI 0.47–0.76), p < 0.001], and mitral valve disease [OR 0.73 (95% CI 0.57–0.94), p = 0.015].
