급성심근경색에서 Doppler 심초음파도로 진단된 승모판폐쇄부전
정진홍(Jin Hong Chung),황진용(Jin Yong Whang),곽충환(Choong Hwan Kwak),채성철(Schung Chull Chae),전재은(Jae Eun Jun),박의현(Wee Hyun Park) 대한내과학회 1989 대한내과학회지 Vol.36 No.4
N/A In 40 patients with acute myocardial infarction (MI), mitral regurgitation (MR) was determined from the apical 4-chamber and parasternal long-axis views with pulsed Doppler and compared with physical and echocardiographic findings. MR was detected in 19 of the 40 patients (48%) and had a similar frequency in patients with anterior (12 of 24 or 46%) and inferior MI (7 of 14 or 50%). A systolic murmur was heard in 8 of 19 patients with MR detected by Doppler and the murmur was directly related to the degree of Doppler MR, Left atrial and left ventricular (LV) dimensions, mitral annulus circumference and LV ejection fraction were similar in patients with and without Doppler MR. However, the prevalence of Dopopler MR in patients with an LV ejection<30% and/or LV diastolic dimension>5.7cm was 71% (12 of 17) but in those without both it was only 30% (7 % of 23).

Background: Acute adaptive vascular remodeling occurs in active and unstable inflammatory plaques. It has been suggested that the adaptive coronary vascular remodeling, in patients with acute coronary syndrome (ACS), may be systemic and may show similar vascular remodeling in the carotid arteries. We investigated the ultrasonographic features of the common carotid artery (CCA) to determine whether the arterial expansive remodeling found in the coronary artery occurs in the carotid arteries of patients with ACS. Methods: We measured lumen diameter (LD), interadventitial diameter (IAD) and intima media thickness (IMT) using a B-mode ultrasound in both common carotid arteries in patients with ACS (N=74) and chronic stable angina (CSA) (N=31). Positive remodeling was arbitrarily defined as an IMTmax>1 mm and IAD>8 mm and negative remodeling as an IMTmax>1 mm and IAD<7 mm. Other values were defined as no remodeling. Results: There were no significant differences in LD IAD and maximal IMT of the right CCA and the left CCA in comparisons between the ACS and the CSA patient groups. There were no differences for number of cases with no remodeling or differences in positive and negative remodeling in the right common carotid artery and left common carotid artery in comparisons between the ACS and CSA patient groups. . Presence of plaque in both common carotid arteries showed similar frequency in the ACS and CSA patient groups. The characteristics of carotid artery plaques were not different in the two groups. The remodeling index (IAD/LD) was correlated with IMTmax (right CCA r=0.797, p<0.001; left CCA r=0.860, p<0.001). Conclusions: The common carotid arterial structure of ACS patients was not different from that of CSA patients. Therefore, these results suggest that the expansive arterial remodeling, due to coronary inflammatory plaques, appears to take place locally rather than systemically.(Korean J Med 71:266-275, 2006)
