Patient Population
We studied 25 consecutive patients with DCM who were in sinus rhythm and who had been referred to our institution for diagnostic tests between May 1995 and May 1998. The 25 patients with DCM showed no signs of significant stenosis or obstruction of the coronary arteries; however, LV dilation and diffuse asynergy of the LV wall were observed.
Exclusion criteria included (1) hemodynamically significant valvular heart disease, (2) right or left bundle branch block, (3) β-blocker or digoxin therapy,
Clinical and M-Mode Echocardiographic Variables
No significant differences were seen in age and heart rate between the DCM and control groups (Table 1). DCM , Dilated cardiomyopathy; HR , heart rate; LVDd , end-diastolic left ventricular dimension; LVDs , end-systolic left ventricular dimension; %FS,Group No. Age (y) HR (bpm) LVDd (cm) LVDs (cm) %FS (%) LAD (cm) Control 22 57 ± 10 78 ± 11 4.5 ± 0.4 2.6 ± 0.4 41 ± 6 3.3 ± 0.4 DCM 25 57 ± 11 84 ± 12 6.3 ± 0.8* 5.1 ± 1.0* 18 ± 6* 4.1 ± 0.4* *< .0001 vs control group.
DISCUSSION
Usually, LV ejection fraction,18, 19, 20, 21 maximum elastance (Emax) as a parameter relating instantaneous intraventricular pressure to volume,22 end-systolic wall stress,17 and the mean rate of circumferential fiber shortening23 are used to evaluate the LV systolic function. However, these parameters are influenced by loading conditions or require the use of an invasive method. The LV myocardium consists of circumferential fibers of the mid-wall and longitudinal fibers of the subendocardial
