MONDAY, April 15, 2024 (HealthDay News) — The prevalence of silent cerebral infarction (SBI) and cerebral small vessel disease (CSVD) is high among patients with heart disease, according to a published review. This is true whether or not someone has had a stroke. In the April 23 issue neurology.

Zien Zhou, MD, PhD, of the George Institute for Global Health at the University of New South Wales in Sydney, and colleagues conducted a systematic review examining the prevalence of SBI and CSVD in adults with atrial fibrillation and coronary artery disease. , heart failure or cardiomyopathy, valvular heart disease, patent foramen ovale (PFO), etc. Data were extracted from his 221 observational studies.

The researchers found that the prevalence of SBI, hiatus, white matter hyperintensity/hypoattenuation (WMH), and microbleeds were 36, 25, 62, and 27 percent, respectively. Stratification by studies that recruited participants with a recent stroke showed no differences in SBI prevalence between subgroups. Comparable results were obtained in participants with various heart diseases, except for participants with SBI (21%) and his PFO, where the prevalence of CSVD was lower. Meta-regression showed that age and increased hypertension were associated with increased SBI and WMH. Although the prevalence of microbleeds did not differ between patients with and without heart disease, there were differences in the prevalence of SBI and WMH (prevalence, 2.3 and 1.7, respectively).

“In summary, people with heart disease have a high prevalence of hidden cerebrovascular changes, which is similar in people who have had a recent stroke and people who have not had a recent stroke.” are writing.
