The effect of left ventricular longitudinal strain on left atrial function and ventricular filling in hypertension

•Reduced left ventricular long axis systolic function occurs in hypertension.•This leads to reduced left atrial filling and emptying.•This leads to reduced left ventricular filling.•Long axis ventricular systolic function is important for ventricular filling.•Normal long axis ventricular systolic function is important for diastolic function.
