ABSTRACT
Objective:To explore the correlation between the level of heart rate deceleration (DC), serum homocysteine(Hcy), the scope and extent of coronary artery lesion in coronary heart disease patients with hypertension.Methods:From January 2019 to October 2019, 103 coronary heart disease patients with hypertension who were diagnosed and hospitalized in cardiovascular department of Binzhou Central Hospital were selected as coronary heart disease(CHD) group, and 52 patients with simple hypertension were selected as control group.The serum Hcy levels of the two groups were measured and analyzed.The DC value and the difference of the two groups were analyzed.The degree of coronary artery lesion was evaluated by the number of coronary artery lesion and Gensini score.The relationship between DC, Hcy and the degree of coronary artery lesion was analyzed.Results:Compared with the control group, the DC value of CHD group was significantly lower [(6.02±1.97)ms vs.(4.97±1.59)ms, t=-3.989, P<0.05], and the serum Hcy level was increased [(11.46±4.38)μmol/L vs.(16.79±6.31)μmol/L, t=4.260, P<0.05]. In the CHD group, the DC values and Gensini scores of the patients with single vessel lesion, double vessel lesions and three vessel lesions were (5.52±1.34)ms, (5.06±1.29)ms, (4.39±1.19)ms, (21.35±17.10)points, (26.93±18.18)points, (49.39±30.14)points, respectively.The DC value of patients with three vessel lesions was lower than that of patients with single vessel lesion( F=7.349, P<0.05), and the Gensini score was higher( F=13.487, P<0.05). There were no statistically significant differences in DC value and Gensini score between patients with three vessel lesions and those with two vessel lesions and those with single vessel lesion( P>0.05). The serum Hcy levels of patients with single, double and three vessel lesions were (14.67±5.97)μmol/L, (15.85±6.29)μmol/L and (16.97±7.13)μmol/L, respectively.The difference among the three groups was statistically significant ( F=12.427, P<0.05). There was a negative correlation between DC and Gensini score( r=-0.310, P<0.05), and a positive correlation between serum Hcy and Gensini score( r=0.369, P<0.05). Conclusion:The DC value and Hcy level in coronary heart disease patients with hypertension are significantly decreased, which are closely related to the degree of coronary artery lesion.
