The Relevant Indexes' Changes of UCG in Patients with Grade 1 Hypertension

Objective To observe the earlier changes of left heart structure and function in patients with Grade 1 hypertension.Methods 65 patients with Grade 1 hypertension were measured on the left atrial diameter(LAD),left ventricular diameter,thickness of ventricular,mass index and evaluate the left ventricular systolic and diastolic function by UCG.Results Compaired to 50 normal controls,the LAD and left ventricular diastolic function of the patients(38.06±3.68 mm,0.72±0.11) was significantly different with those of 50 normal controls(29.86±3.08 mm,1.18±0.08)(P0.05,P0.01).while there were no significance in left ventricular diameter,thickness of ventricular,mass index and left ventricular contraction function between two groups(P0.05).Condusion By UCG examination,decrease of left ventricular diastolic function and left atrial enlargement are the earlier heart changes in Grade 1 hypertension patients.
