Why the study?
Can real-time 3-dimensional echocardiography detect left ventricular dysfunction in chronic alcoholics compared to controls?
Can real-time 3-dimensional echocardiography detect left ventricular dysfunction in chronic alcoholics compared to controls?
Real-time 3D echocardiography is feasible and effective for detecting early increases in LV volumes and mass in asymptomatic alcoholics, as well as functional changes in symptomatic patients.
3DE-detected LV changes in alcoholics remain hypothesis-generating; prospective studies needed before clinical adoption.
Chronic alcohol consumption may lead to progressive cardiac dysfunction. The aim of this study was to evaluate the feasibility of using real-time 3-dimensional echocardiography (3DE) on assessing left ventricular (LV) function in chronic alcoholics.We classified 92 male alcoholics into mild, moderate, and severe groups; 30 age-matched controls were also recruited. LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), LV ejection fraction (LVEF), LV mass (LVM), LV mass index (LVMI), and systolic dyssynchrony index (SDI) were measured by 3DE and 2-dimensional echocardiography (2DE).Compared to the control group, LV volume and mass were higher in the moderate and severe alcoholic groups (P < 0.05). The severe alcoholic (symptomatic) group demonstrated decreased LVEF and increased SDI (detected by 3DE) (P < 0.05).Real-time 3DE can detect the increases of LV volumes and mass in asymptomatic alcoholics, and the changes of LVEF and systolic synchrony index in symptomatic alcoholics.
