Ultrasonographic assessment of cardiac function and disease severity in coronary heart disease

Table 3 Comparison of ultrasonic parameters in patients with different degrees of coronary heart disease (mean ± SD)

Group	Number	E/A	LVDd (mm)	LAD (mm)
Mild	43	1.69 ± 0.50	51.97 ± 3.88	38.81 ± 2.56
Moderate	38	1.44 ± 0.41	59.95 ± 4.14	45.15 ± 2.97
Severe	25	1.13 ± 0.36	67.70 ± 6.11	49.09 ± 4.05
t/P value (Grade II vs III)		2.441/0.017	8.952/0.000	10.319/0.000
t/P value (Grade III vs IV)		3.078/0.003	6.009/0.000	4.453/0.000

E/A: Early-to-late diastolic blood flow velocity ratio; LVDd: Left ventricular end-diastolic volume; LAD: Left atrial diameter.
