Note: UM: microalbumin; LVPWd: left ventricular posterior wall thickness during diastolic period; IVSd: diastolic septal thickness; LVIDd: left ventricular end-diastolic diameter; β1-AA: β1 adrenergic receptor autoantibody; AT1-AA: autoantibody to angiotensin II1 receptor; EF: ejection fraction; FS: left ventricular short-axis shortening rate; SBP: systolic blood pressure; DBP: diastolic blood pressure.
