Abstract:
Objective To investigate the effects of homocysteinemia (HHcy) and hypertension on left ventricular re?modeling. Methods A total of 275 patients with coronary heart disease were divided into four groups including H-type hy? pertension group (n=96), non-H-type hypertension group (n=44), HHcy+non-hypertension group (n=53) and control group (n=65) based on their blood pression levels and plasma HHcy levels. The serum levels of glucose (Glu), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high-density lipoprotein (HDL) were compared between groups. The left ventricular end systolic diameter (LVESD), left ventricular end diastolic diameter (LVEDD), left ventricular posterior wall thickness (LVPWT), ventricular septal thickness (IVST) and left ventricular mass index (LVMI) were observed in four groups. The proportion of patients with left ventricular remodeling was also compared between four groups. The influence fac?tors of left ventricular remodeling were analysed. Results There were no significant differences in biochemical parameters except Hcy level between frour groups. The values of LVMI, left ventricular wall thickness and the proportion of patients with left ventricular remodeling were significantly higher in H-type hypertension group than those of other three groups ( P<0.05). The Hcy level was positively correlated with LVMI and left ventricular wall thickness. Logistic regression analysis showed that HHcy and hypertension were the risk factors of left ventricular remodeling (OR=7.443, 7.754 and 9.948,P<0.05). The risk factors of left ventricular remodeling were higher in patients with both HHcy and hypertension than those in patients with HHcy or hypertension. Conclusion Homocysteine and higher systolic pressure are independent risk factors for left ventricular remodeling and they have a synergistic effect on leading to left ventricular remodeling.
