Abstract/OtherAbstract:
AIMS: To assess the relationship between asymmetric septal hypertrophy (ASH) and manifestations of coronary artery disease (CAD).
METHODS AND RESULTS: A total of 5128 consecutive patients with proven diagnosis of CAD were examined. There were 2469 patients with left ventricular (LV) hypertrophy (LVH) (48.2%), among whom 297 (5.8%) had ASH (echocardiographic ventricular septum thickness to LV posterior wall thickness ratio > or =1.3). There were more male patients with ASH than patients with symmetric LVH (SLVH). ASH patients were significantly older and more obese, more of them were in NYHA class III/IV compared with SLVH patients. The prevalence of prior myocardial infarction (MI), systemic hypertension, heart rhythm disorders were higher in patients with ASH compared with SLVH patients. The groups differed significantly in echocardiographic parameters: LV and right ventricular (RV) end-diastolic dimensions, LV ejection fraction, left atrial dimension, extent of LV wall motion abnormalities, wall motion score index, LV mass/body surface area, signs of prior MI, and frequency of moderate mitral regurgitation. The frequency of stenosis and more severe (>90% stenosis) lesion of right coronary artery (RCA) and left circumflex artery (LCA) were higher in patients with ASH. Multivariate analysis identified that heart rhythm disorder, LV and RV end-diastolic dimensions, aortic root diameter, impaired LV ejection fraction, echocardiographic signs of previous MI, LV mass, and severe lesions of RCA were independently associated with ASH.
CONCLUSION: In patients with CAD, ASH is associated with significant atherosclerosis of RCA and LCA, and more severe clinical manifestations of CAD and impaired LV function.
