This study investigates the correlation between coronary artery disease (CAD) and ambulatory arterial stiffness index (AASI) in patients with H-type hypertension and coronary heart disease (CHD). The results show that AASI is significantly increased in patients with H-type hypertension and CHD, and it is associated with the severity of CAD.
Objective To investigate coronary artery disease (CAD) and its correlation with the ambulatory arterial stiffness index (AASI) in patients with H-type hypertension (essential hypertension combined with hyper-homocysteinemia) and coronary heart disease (CHD). Methods Patients with essential hypertension and CHD who were undergoing coronary angiography were enrolled. The general clinical data, biochemical indicators, ambulatory blood pressure monitoring results and coronary angiography results of the selected patients were collected, and the AASI and Gensini scores were calculated. According to homocysteine (Hcy) levels, the patients were divided into two groups: a study group and a control group. The differences in general clinical data, biochemical indexes, AASI scores and degree of coronary artery lesions between the two groups were compared. The correlation between the AASI and the Gensini score and the relationship between the AASI and the Gensini score of CAD and various factors were analyzed. Results Compared with the control group, the Hcy level in the study group was significantly increased (8.16 & PLUSMN; 2.33 vs 19.20 & PLUSMN; 2.36, P = .001). The 24-h diastolic blood pressure (DBP) in the study group was significantly lower than that in the control group (76.38 & PLUSMN; 9.33 vs 79.91 & PLUSMN; 9.25, P = .002), and the AASI was significantly higher than in the control group (0.62 & PLUSMN; 0.81 vs 0.420 & PLUSMN; 0.70, P = .001). The number of patients having coronary stenoses with a Gensini score of & LE; 38 was significantly lower in the study group than in the control group (21.3% vs 49.4%, P < .001). The number of patients with a Gensini score of & GE; 51 in the study group was significantly higher than in the control group (22.0% vs 18.8%, P < .001). There was a significant positive correlation between the AASI and the Gensini score in the study group (R = 0.732, P < .001). Hypertension duration (& beta; = 0.168), diabetes history (& beta; = 0.236), 24-h SBP (& beta; = 0.122), 24-h DBP (& beta; = -0.131), low-density lipoprotein cholesterol (& beta; = 0.134) and Hcy (& beta; = 0.233) were the influencing factors for AASI (P < .05). Both Hcy * AASI (& beta; = 0.356) and Hcy x 24-h HR (& beta; = 0.331) had a synergistic effect on the Gensini score (P = .017), with Hcy * AASI having a more significant effect on the Gensini score (P < .001). Conclusion The AASI was significantly increased in patients with H-type hypertension and CHD, which was associated with the severity of CAD. Therefore, Hcy levels and the AASI have a synergistic effect when evaluating the severity of CAD in patients with hypertensive CHD.
