ABSTRACT
Objective To evaluate the association between LDL-C and ischemic stroke in patients with nonvalvular atrial fibrillation (AF).Method A total of 2 470 patients with nonvalvular AF were included in the present study.The clinical data and laboratory examination results of the patients in the hospital were collected.The subjects were either divided into the ischemic stroke history (n =560),and non-ischemic stroke history groups (n =1 910),or divided into the low-middle risk (n =566) and high risk groups (n =1 904) based on CHA2 DS2-VASc score.Results There were significant differences in the proportion of Han,the ratio of gender,age,hemoglobin,hematocrit,ALT,serum uric acid,HDL-C and LDL-C between the patients with ischemic stroke history and without (all P ＜ 0.05).Similarly,there were significant differences in the proportion of Han,the ratio of gender,age,white blood cell count,hemoglobin,hematocrit,platelet count,ALT,albumin,TG and LDL-C between subjects in the low-middle risk group and those in the high risk group (all P ＜ 0.05).A logistical regression analysis showed that LDL-C was an independent risk factor for both the ischemic stroke history (OR 2.089,95％ CI 1.860-2.347,P ＜0.05),and future ischemic stroke risk (OR 1.270,95％ CI 1.079-1.494,P ＜ 0.05) in patients with nonvalvular AF.Conclusion LDL-C is associated with ischemic stroke in patients with nonvalvular AF,and it is also an independent risk factor for future ischemic stroke in these patients.
ABSTRACT
Objective To investigate the effect of folic acid intervention on plasma homocysteine (Hcy) metabolic changes and pulse wave velocity(PWV)in patients with type H hypertension. Methods Patients(hos-pitalized from March 2014 to December in our hospital)with H type hypertension were randomly divided into treat-ment group and control group randomly ,and were given routine antihypertensive drug therapy. Treatment group was given oral folic acid 0.8 mg,1 times a day,the control group was given placebo,1 times a day. All patient were treated for 12 months. Changes of plasma Hcy and PWV levels were observed. Results 432 patients(Han nationality)with type H hypertension were enrolled in this study with the age of 61.7 ± 13.6 years old and the ratio of men and women is 1.3:1. The most common diseases were coronary heart disease and type 2 diabetes mellitus. 2 groups were treated for a period of 12 months,with follow-up time from 6 to 10 months(average duration in 8 months). After treatment,the difference between plasma Hcy(Z=-7.63,P=0.000)and PWV(Z=-3.16,P=0.002)levels of the two groups were statistically significant. Conclusion Folic acid intervention can significantly reduce the level of plasma Hcy in patients with type H hypertension ,slow down the progression of atherosclerosis and reduce the risk factors of cardiovascular disease.
