Objectives: This study aimed to investigate the associations between changes in blood pressure (BP) and cerebral small vessel disease (CSVD).

Methods: This study included 401 participants in the magnetic resonance imaging (MRI) sub-study conducted between 2018 and 2020 as a part of the Multidomain Interventions to Delay Dementia and Disability in Rural China project. MRI markers of CSVD were assessed based on international criteria. Individualized linear regression models evaluated changes in BP by estimating the trend of blood pressure changes over time and fitting a straight line from 2014 to 2018. The data were analyzed using logistic and general linear regression models.

Result: The mean age of the participants was 64.48 ± 2.69 years, with 237 (59.1%) being females. Increases in systolic BP in later life were significantly associated with larger volumes of periventricular white matter hyperintensity (WMH), greater perivascular spaces in the basal ganglia (BG-PVS) burden, and the presence of deep lacunes and cerebral microbleeds. Additionally, increases in diastolic BP in later life were significantly associated with the presence of infratentorial and deep lacunes.

Conclusions: CSVDs are associated with increased exposure to elevated BP later in life.

Disease screening aims to identify individuals at risk for specific conditions. It is expected that an early detection allows for early intervention, with improved outcomes. However, large scale screening programs may not only have implications on resources, patient outcomes may not improve but may worsen if screening for the targeted disease has not been carefully designed and executed.
