Background: Cerebral Amyloid Angiopathy (CAA) disease course is highly variable even in hereditary forms. Sex may be a possible modifying factor. We investigated biological sex differences in clinical disease course and magnetic resonance imaging-markers in sporadic (sCAA) and Dutch-type hereditary CAA (D-CAA). Methods: Patients with D-CAA and sCAA were included from hospital and research databases of the Leiden University Medical Center (2012–2020) and Massachusetts General Hospital (1994–2012). Key outcomes were: sex differences in symptomatic intracerebral hemorrhage (sICH) onset, recurrence and survival (analyzed using Kaplan Meier survival and regression analyses), and sex differences in magnetic resonance imaging-markers in D-CAA (explored using scatterplots), and in sCAA (investigated using regression analysis). Results: We included 136 patients with D-CAA (mean age 57 years, 56% women, 64% with previous sICH) and 370 patients with sCAA (mean age 76 years, 51% women, all with previous sICH). Men and women with D-CAA did not differ for sICH onset (median age 54 in men and 56 in women [ P =0.13]). Men with D-CAA had a slightly higher number of sICH compared with women (median 2 versus 1; adjusted RR, 1.5 [95% CI, 1.1–1.9]) and a shorter interval between the first and second sICH (median 1.8 years for men and 3.1 years for women, P =0.02). Men with sCAA had their first sICH at an earlier age (median 75 versus 78 years, respectively, P =0.003) and more lobar microbleeds (median 1 versus 0, P =0.022) compared with women with sCAA. No substantial differences were found in the other magnetic resonance imaging markers. Survival after first sICH was comparable between sexes for D-CAA ( P =0.12) and sCAA ( P =0.23). Conclusions: Men with CAA seem to have an earlier onset (sCAA) and more hemorrhagic disease course (sCAA and D-CAA) compared with women. Future studies are necessary to confirm these findings and determine the underlying role of sex-related factors.

Background: Blood pressure (BP) control represents a crucial intervention to improve long-term outcomes following spontaneous intracerebral hemorrhage (ICH). However, fewer than half of ICH survivors achieve target treatment goals. ICH survivors are also at very high risk for poststroke depression, which may contribute to inadequate BP control. We, therefore, sought to determine whether depressive symptoms after ICH are associated with inadequate BP control. We also investigated whether associations between depression after ICH and BP measurements were mediated by treatment with selective serotonin reuptake inhibitors or norepinephrine-serotonin reuptake inhibitors antidepressants. Methods: We leveraged data from a single-center longitudinal study of ICH conducted at Massachusetts General Hospital (Boston, MA) between 2006 and 2018. We collected data from semiautomated review of electronic health records, baseline and follow-up interviews, and computed tomography imaging. Information on BP measurements, depression diagnoses, antidepressants medication use, and medical visits were collected longitudinally and analyzed using mixed effects models. Primary outcomes included systolic and diastolic BP measurements during long-term follow-up after ICH. Results: We included 1243 consecutive ICH patients without pre-stroke depression history. Of these, 721 (58%) were diagnosed with incident depression over a median follow-up time of 52.8 months (interquartile range, 42.1–60.5). Depression onset was associated with subsequent increase in systolic (+8.3 mm Hg, SE, 2.4 mm Hg, P =0.012) and diastolic (+4.4 mm Hg, SE, 1.2 mm Hg) BP measurements. Resolution of depressive symptoms was associated with subsequent decrease in systolic (−5.9 mm Hg, SE, 1.4 mm Hg, P =0.031) and diastolic (−3.4 mm Hg, SE, 1.1 mm Hg, P =0.041) BP measurements. We also found associations between higher systolic BP measurements and use of selective serotonin reuptake inhibitor and noradrenaline-serotonin reuptake inhibitor antidepressants, independent of whether depression symptoms were active or not (all P Conclusions: ICH survivors displayed increasing BP values after receiving a diagnosis of depression, followed by decreasing values among those experiencing resolution of depressive symptoms. Use of selective serotonin reuptake inhibitor and noradrenaline-serotonin reuptake inhibitor antidepressants was independently associated with higher systolic BP measurements. Clinicians ought to closely monitor BP for ICH survivors being treated for depression, especially using selective serotonin reuptake inhibitor and noradrenaline-serotonin reuptake inhibitor. Future studies will also be required to investigate the mechanisms underlying these associations.

Background Survivors of intracerebral hemorrhage (ICH) are at high risk for recurrent stroke, which is associated with blood pressure control. Because most recurrent stroke events occur within 12 to 18 months of the index ICH, rapid blood pressure control is likely to be crucial. We investigated the frequency and prognostic impact of uncontrolled short‐term hypertension after ICH. Methods and Results We analyzed data from Massachusetts General Hospital (n=1305) and the University of Hong Kong (n=523). We classified hypertension as controlled, undertreated, or treatment resistant at 3 months after ICH and determined the following: (1) the risk factors for uncontrolled hypertension and (2) whether hypertension control at 3 months is associated with stroke recurrence and mortality. We followed 1828 survivors of ICH for a median of 46.2 months. Only 9 of 234 (4%) recurrent strokes occurred before 3 months after ICH. At 3 months, 713 participants (39%) had controlled hypertension, 755 (41%) had undertreated hypertension, and 360 (20%) had treatment‐resistant hypertension. Black, Hispanic, and Asian race/ethnicity and higher blood pressure at time of ICH increased the risk of uncontrolled hypertension at 3 months (all P P Conclusions Among survivors of ICH, >60% had uncontrolled hypertension at 3 months, with undertreatment accounting for the majority of cases. The 3‐month blood pressure measurements were associated with higher recurrent stroke risk and mortality. Black, Hispanic, and Asian survivors of ICH and those presenting with severe acute hypertensive response were at highest risk for uncontrolled hypertension.

Introduction: Survivors of Intracerebral Hemorrhage (ICH) are at high risk of recurrent stroke. This risk is inversely proportional to average Blood Pressure (BP) after ICH. Racial/ethnic minority ICH survivors in the US demonstrate greater hypertension severity after ICH and are at higher risk of recurrent cerebral bleeding. Since most recurrent strokes occur within 12-18 months of index ICH, rapidly achieving BP control is likely to be crucial. We investigated the frequency, prognostic impact, and racial/ethnic disparities in uncontrolled short-term hypertension (HTN) after ICH. Methods: We analyzed data from prospective ICH cohort studies at Massachusetts General Hospital (MGH-ICH, n=1305) and the University of Hong Kong (HK-ICH, n=523). We classified HTN as controlled, uncontrolled or treatment-resistant and determined: 1) risk factors for uncontrolled and treatment-resistant HTN; and 2) whether HTN control at 3 months is associated with long-term BP control, stroke recurrence and mortality across self-reported race/ethnicity groups. Results: We followed 1828 ICH survivors (1128 White, 565 Asian, 59 Hispanic, 49 Black, 27 other) for a median of 46.2 months. Only 9 of 172 (5%) recurrent strokes occurred before 3 months after ICH. At 3 months, 713 participants (39%) had controlled HTN, 755 (41%) had undertreated HTN, and 360 (20%) had treatment-resistant HTN. BP measurements at 3 months were highly correlated with measurements during follow-up (p Conclusions: Most ICH survivors have inadequate HTN control 3 months after ICH, with under-treatment accounting for the majority of cases. Three-month BP measurements are associated with inadequate long-term HTN control, higher recurrent stroke risk and mortality. ICH survivors self-reporting as Black, Hispanic or Asian appear to be at highest risk for uncontrolled HTN. Optimizing HTN control at 3 months is a unique opportunity to address racial/ethnic disparities in quality of care among survivors of primary ICH.

Introduction: Intracerebral Hemorrhage (ICH) is an acute manifestation of underlying Cerebral Small Vessel Disease (CSVD), usually Cerebral Amyloid Angiopathy (CAA) or Hypertensive Arteriopathy (HTNA). CSVD-related imaging and histopathology findings were previously associated with increased depression incidence in the general population. CSVD evaluation via neuroimaging may therefore provide insight on depression risk among ICH survivors. We sought to determine whether hematoma location and CSVD MRI markers are associated with depression risk (before and after ICH) and resistance to treatment. Methods: We analyzed data from the single-center longitudinal ICH study conducted at Massachusetts General Hospital (MGH-ICH) since 1994 and currently ongoing. All participants underwent CT and MRI imaging, and were then followed longitudinally via a combination of semi-automated review of Electronic Medical Records (EMR) and phone-based research interviews. We extracted information for hematoma location and MRI neuroimaging markers of CSVD subtype and severity. We conducted univariable and multivariable analyses of depression prevalence before ICH, new-onset of depression after ICH, and resolution of depressive symptoms during follow-up. Results: We enrolled 612 ICH survivors, and followed them for a median of 46.3 months (Inter-Quartile Range: 35.5-58.7). Multiple CSVD-related markers were associated with depression outcomes of interest. Survivors of CAA-related lobar ICH were at highest risk for depression (before and after ICH), as well as treatment resistance (all p Conclusions: CSVD severity on neuroimaging is associated with depression prevalence and treatment-resistance among ICH survivors. CAA-related ICH survivors are at higher risk for depression (both before and after ICH) than patients diagnosed with HTNA-related ICH. The potential role of CSVD evaluation in guiding care of ICH survivors with -or at high risk for- depression warrants additional investigative efforts
