The distribution and epidemic characteristics of cerebrovascular disease in followed-up hypertension patients

Abstract To explore distribution and epidemic characteristics of CVD in followed-up HP patients. Using the Hypertension Follow-up Management System database in Jiading district in Shanghai. We designed a retrospective cohort study that included all followed-up hypertension patients between 2002 and...

Using the Hypertension Follow-up Management System database in Jiading district in Shanghai. We designed a retrospective cohort study that included all followed-up hypertension patients between 2002 and 2020. The endpoint was the occurrence of CVD confirmed by the hospital; otherwise, the patients were tracked until September 30, 2020. Record information of every patient has been collected in the registration card and each followed-up record. Among 223,097 observational followed-up HP patients, the total number of person years of observation was 4,244,421.25 person-year, 11,143 patients had developed CVD from hypertension before the deadline, the total incidence density was 0.00263 per person-year (male 0.00292; female 0.00238) and the complication ratio of CVD in HP patients was 4.99% (male 5.25%; female 4.76%) during follow-up period. The proportion of ischemic cerebrovascular, hemorrhagic cerebrovascular and unclassified stroke was respectively 71.18%, 5.95% and 22.87% in hypertensive CVD. Complication ratio of CVD increased with age, the group under 30 was 0, and the group over 70 was the highest (6.90%). The complication ratio of grad I, grad II and grad III blood pressure were respectively 4.79%, 4.96% and 6.13%. The complication ratio was 4.92% in only high systolic blood pressure patients; 17.23% in only high diastolic blood pressure patients; 4.59% in high systolic and diastolic blood pressure patients. The peak of complication ratio of CVD was 9–10 years after the registered and followed-up. The proportion of CVD cases in HP patients from April to June was the largest in the four seasons; the proportion of patients from October to December was the minimum. HP patient was prone to falling cerebrovascular disease; the main type of disease was cerebral infarction. Complication ratio in male incidence was higher than that in female. The complication ratio of CVD increased with age, blood pressure and duration of HP patients. It had seasonal characteristics, which was relatively high from April to June within year.An-le LiShuai ZhuZhi-hao HuQian PengXiang FangYi-ying ZhangNature PortfolioarticleMedicineRScienceQENScientific Reports, Vol 11, Iss 1, Pp 1-8 (2021)
