  1. β is adjusted regression coefficient. Factors with P < 0.1 in the univariable analyses were included in the backwards stepwise multiple linear regression model
  2. Left atrial (LA), left ventricular (LV), longitudinal peak diastolic strain rate (PDSR), perfusion index (PI), myocardial perfusion reserve index (MPRI), glycosylated hemoglobin (HbA1c)
