Blood pressure does no predict lacunar infarction

J van Gijn, C L Kraaijeveld

    Journal of Neurology, Neurosurgery, and Psychiatry
    |February 1, 1982

    Summary

    Higher systolic blood pressure was observed in patients with lacunar infarcts compared to large cerebral infarcts. However, large infarcts were more common across all blood pressure levels in this atherothrombotic arterial disease study.

    Area of Science:

    • Neurology
    • Cardiovascular Science
    • Radiology

    Background:

    • Atherothrombotic arterial disease is a significant cause of acute hemispheral infarcts.
    • Distinguishing between large cerebral infarcts and lacunar infarcts is crucial for understanding disease mechanisms and patient outcomes.

    Purpose of the Study:

    • To investigate the relationship between blood pressure levels and the type of cerebral infarction (large vs. lacunar) in patients with acute hemispheral infarcts.
    • To determine if blood pressure is a differentiating factor between large and lacunar infarcts in the context of atherothrombotic disease.

    Main Methods:

    • Retrospective analysis of 134 patients with acute hemispheral infarcts confirmed by computed tomography.
    • Exclusion of infarcts attributed to causes other than atherothrombotic arterial disease.
    • Comparison of systolic blood pressure measurements between patients with large infarcts and those with lacunar infarcts.

    Main Results:

    • Lacunar infarcts were identified in 26 patients, while large infarcts were present in 108 patients.
    • Patients with lacunar infarcts exhibited higher systolic blood pressure compared to those with large infarcts.
    • Despite this difference, large infarcts were predominant across all measured blood pressure ranges, indicating significant overlap.

    Conclusions:

    • While higher systolic blood pressure is associated with lacunar infarcts, it does not reliably differentiate between large and lacunar infarct types in atherothrombotic disease.
    • Computed tomography is essential, alongside clinical signs, for diagnosing lacunar infarcts.
    • Blood pressure management remains critical in patients with atherothrombotic arterial disease and stroke.
