Coronary artery disease with subsequent myocardial ischemia is a common cause of morbidity and mortality in the United States, and data are scarce on the prevalence of the disease in blacks.
Regional wall motion abnormality correlates either directly or indirectly with myocardial ischemia.
This study examines the two-dimensional (2-D) echocardiography of patients =45 years for men and =55 years for women at Metropolitan Nashville General Hospital, Nashville, Tennessee.
A total of 601 2-D echocardiographic studies were performed on patients who presented with symptoms and signs of cardiovascular disease.
Of these, 377 (62.7%) met the age criteria and formed the study group ; 92 were excluded for various reasons, leaving 285 (75%) in the analysis group.
A total of 80 (28.1%) patients had regional wall motion abnormality while 205 (71.9%) did not.
On analysis of the 80 patients with regional wall motion abnormality, the segment of the heart commonly affected was the septal area, although more than one segment of the myocardium was affected in all of the patients.
A total of 36 (45%) patients had normal left ventricular size.
In relation to race, blacks had a higher prevalence of regional wall motion abnormality compared with whites (29.2% versus 26.2%, respectively), but the difference was not statistically significant.
These prevalence rates indicate the importance of looking for this abnormality during echocardiographic evaluation of a patient. (...)
