ABSTRACT

Objective To study the length of hypertension history and its related factors in patients with both ischemic cerebral vascular disease(ICVD) and hypertension.Methods The profile of hypertension history in ICVD patients from our hospital between 1990 and 1999 was summarized.Hypertension history meant the time interval between onset of first symptomatic ICVD and establishment of diagnosis of hypertension.The related factors' influence on the length of hypertension history was analyzed by means of multiple linear regression model.Results In ICVD patients with hypertension,the mean length of hypertension history was 14.29?10.63 years,the median was 11 years.In multiple linear regression model,increased age when hypertension was diagnosed,diabetes mellitus,smoking,peasant(army man as control group) were independent factors that shortened hypertension history.Antihypertensive treatment independently lengthened hypertension history.Conclusion The length of hypertension history varies greatly,50% of patients developed the first ICVD in 11 years after the diagnosis of hypertension was established .Coexisting smoking and diabetes mellitus hasten while control of arterial blood pressure postpone onset of ICVD in patients with hypertension.
