Coronary @entity730 , a type of @entity453 , has recently been closely examined in clinical cardiology because its presence may influence the selection of interventional therapy. In addition, plaque instability is one of the most important factors in the mechanism of @entity1187 , and @entity460 deposit is frequently detected in advanced lesions. However, little is known about the clinical significance of coronary @entity730 . The incidence of @entity460 deposits was investigated in the culprit lesions (culprit coronary @entity730 ) of @entity1 with serious @entity453 to discover any cardioprotective effect. Initial coronary angiography was performed in 179 consecutive @entity1 with acute @entity583 with Q wave on electrocardiography (AMI group; male 139, female 40, mean age 60.2 +/- 10 yr) and in 119 consecutive @entity1 with stable effort angina pectoris (SAP group; male 78, female 41, mean age 63.8 +/- 8 yr) for which balloon plasty or bypass surgery was necessary from 1990 to 1997. Culprit coronary @entity730 was defined positive if the @entity730 deposit was present cinefluoroscopically within 5 mm from the culprit point. The culprit point was defined as the narrowest point after successful intracoronary thrombolytic therapy or the latest point to be dilated during a @entity661 in direct or rescue percutaneous transluminal coronary angioplasty in the AMI group, and the narrowest point of the culprit lesion in the SAP group. There was no statistical difference in clinical background between the 2 groups other than male dominance in the AMI group and high incidence of family history of @entity741 in the SAP group (p < 0.05). Culprit coronary @entity730 in @entity1 over 50 years old was less frequently positive in the AMI group than the SAP group (26% vs 66%, p < 0.005, respectively). In younger @entity1 under 50 years old, the incidence of culprit coronary @entity730 was low (14-15%) in both groups. Culprit coronary @entity730 was frequently positive in the right or the left anterior descending coronary artery in the SAP group (p < 0.005). There was no incidental sex difference of culprit coronary @entity730 . This comparison suggests that if a plaque contains cinefluoroscopically visible @entity730 , it may be regarded as less vulnerable or having a history of chronic process of @entity731 which results in protecting @entity397 .
