Current status of blood pressure control in elderly hypertensive patients under the antihypertensive standard recommended by Chinese experts / 中华老年心脑血管病杂志

ABSTRACT

Objective To analyze the antihypertensive compliance rate,drug use and complication distribution among very old hypertensive inpatients under the antihypertensive standard of 150/90 mm Hg in our country(1 mm Hg=0.133 kPa).Methods A total of 409 hospitalized patients aged ≥80 years and diagnosed with hypertension in all departments of Air Force Medical Center of PLA were enrolled,and according to their clinical outcomes,they were divided into intensive antihypertensive group(106 cases,SBP＜130 mm Hg),standard antihypertensive group(155 ca-ses,SBP 130-149 mm Hg)and non-standard blood pressure group(148 cases,SBP ≥150 mm Hg).The status of blood pressure control was analyze in each group.Results When 150/90 mm Hg was used as the blood pressure standard,25.9％were in the intensive blood pressure group,37.9％were in the standard blood pressure group,36.2％were in the non-standard blood pressure group.The proportion of patients aged＞90 years was significantly lower in the non-standard blood pressure group than the intensive antihypertensive group and the standard anti-hypertensive group(4.1％vs 7.5％and 12.3％,P＜0.05).The ratio of single-drug therapy was significantly higher in the standard antihypertensive group than the intensive antihypertensive group(46.5％vs 32.1％,P＜0.05),and that of dual combination therapy was obviously higher in the intensive antihypertensive group than the standard antihypertensive group(35.8％vs 22.6％,P＜0.05).The proportions of heart damage and cerebrovascular damage were significantly higher(43.4％vs 21.9％,26.4％vs 14.8％),and the proportion of complicated retinopathy was notably lower(11.3％vs 23.9％)in the intensive antihypertensive group than the standard antihypertens-ive group(P＜0.05).Conclusion For very old hypertensive patients in our country,it is more sci-entific and practical to use 150/90 mm Hg as the starting standard for blood pressure reduction.Intensified blood pressure reduction increases cardiovascular and cerebrovascular damages in them instead.
