[Regional contraction of the left ventricle in congestive cardiomyopathy].
Regional analysis of ventricular angiograms obtained at diagnostic cardiac investigation was undertaken in 22 patients with congestive cardiomyopathy and 16 healthy subjects. Applying the concept of radial motion, directed towards the centre of the left ventricle, akinetic zones of 20 to 50% of left ventricle circumference were found in more than half the cases of congestive myopathy. The greater the area of regional abnormal motion, the greater the reduction in haemodynamic variables and left ventricular function. The clinical status of nearly all patients with large akinetic areas deteriorated in the subsequent period of observation (6-48 months, averaging 26 months). But in patients without additional abnormal regional wall motion the clinical condition remained stable. A large akinetic area in congestive myopathy indicates severe reduction in left ventricular function and is an unfavourable prognostic sign.
