Abstract

© 2019, The Author(s), under exclusive licence to Springer Nature Limited. We aimed to evaluate brachial and central blood pressure (BP) estimates and biomarker levels in lacunar ischemic stroke (IS) and other IS subtypes (nonlacunar stroke). We studied 70 functionally independent subjects consecutively admitted to our institution after a first episode of IS. Subjects with previous heart failure were excluded. BP was measured at admission and during the subacute phase of stroke (5–7 days after stroke onset). Aortic pulse wave velocity (aPWV), augmentation index (AIx), and 24 h brachial and central BP (24h-ABPM) were measured by means of a Mobil-O-Graph device during the subacute phase of stroke. Determination of N-terminal prohormone of brain natriuretic peptide (NT-proBNP), urinary albumin excretion, and echocardiography were performed in all subjects. After adjusting for age and clinical severity, lacunar IS had significantly higher levels of BP at admission (systolic BP 173 ± 37 vs 153 ± 28 mmHg, p = 0.006; diastolic BP: 97 ± 21 vs 86 ± 16 mmHg, p = 0.035) and during the subacute phase of stroke (systolic BP 152 ± 23 vs 134 ± 19 mmHg, p = 0.001; diastolic BP: 84 ± 14 and 77 ± 10 mmHg, respectively; p = 0.038) but lower NT-proBNP levels (median: 36,277 vs 274 pg/mL, p = 0.009) than nonlacunar IS. Central BP, aPWV, and AIx were not different between lacunar and nonlacunar IS, neither the rate of target organ damage. In conclusion, patients with a first episode of lacunar IS have higher BP values at admission and during the subacute phase of stroke and lower levels of NT-proBNP, suggesting a closer relationship with hypertension of this IS subtype.
