HR was measured as the average HR during echocardiography, and high HR was defined as resting HR\u2009\u2265\u200970 beats\/minute.

Multivariable logistic regression analysis showed that high HR (odds ratio: 1.04; 95% confidence interval: 1.01\u20131.07; P\u2009=\u20090.01) was independently associated with GLS\u2009&lt;\u200918% in T2DM patients as well as HbA1c, T2DM duration, LVEF, body mass index, and mitral inflow E and mitral e\u2019 annular velocity ratio.
