Abstract
- The incidence of new regional abnormalities of left ventricular wall motion induced by a peripheral cold stimulus has been examined in 75 patients who all underwent coronary arteriography. When analysis was carried out from a cine loop display a new wall motion abnormality had a sensitivity of 12% and a specificity of 100% for coronary artery disease. From stroke volume images the sensitivity was 35% and the specificity 87%. It is concluded that cold pressor induced wall motion changes are too insensitive to be a useful method of screening for coronary artery disease.
