Relationship between β1-AA and AT1-AA and Cardiac Function in Patients with Hypertension Complicated with Left Ventricular Diastolic Function Limitation

Table 4

Value of β1-AA and AT1-AA and their combination in the prediction of diastolic dysfunction.

Subjects	Accuracy	Sensitivity	Specificity	AUC	95% CI
β1-AA	0.860	0.854	0.852	0.844	0.772~0.934
AT1-AA	0.861	0.842	0.813	0.841	0.781~0.869
Combined prediction	0.944	0.931	0.954	0.942	0.881~0.985

Note: β1-AA: β1 adrenergic receptor autoantibody; AT1-AA: autoantibody to angiotensin II1 receptor.
