The Relationship

BackgroundEndovascular thrombectomy (ET) has transformed acute ischemic stroke (AIS) therapy in patients with large vessel occlusion (LVO). Left ventricular systolic dysfunction (LVSD) decreases global cerebral blood flow and predisposes to hypoperfusion. We evaluated the relationship between LVSD, as measured by LV ejection fraction (LVEF), and clinical outcomes in patients with anterior cerebral circulation LVO who underwent ET.MethodsThis multicenter retrospective cohort study examined anterior circulation LVO AIS patients from six international stroke centers. LVSD was measured by assessment of the echocardiographic LVEF using Simpson’s biplane method of discs according to international guidelines. LVSD was defined as LVEF <50%. The primary outcome was defined as a good functional outcome using a modified Rankin Scale (mRS) of 0–2 at 3 months.ResultsWe included 440 AIS patients with LVO who underwent ET. On multivariate analyses, pre-existing diabetes mellitus (OR 2.05, 95% CI 1.24 to 3.39;p=0.005), unsuccessful reperfusion (Treatment in Cerebral Infarction (TICI) grade 0-2a) status (OR 4.21, 95% CI 2.04 to 8.66; p<0.001) and LVSD (OR 2.08, 95% CI 1.18 to 3.68; p=0.011) were independent predictors of poor functional outcomes at 3 months. On ordinal (shift) analyses, LVSD was associated with an unfavorable shift in the mRS outcomes (OR 2.32, 95% CI 1.52 to 3.53; p<0.001) after adjusting for age and ischemic heart disease.ConclusionAnterior circulation LVO AIS patients with LVSD have poorer outcomes after ET, suggesting the need to consider cardiac factors for ET, the degree of monitoring and prognostication post-procedure.

Background: Endovascular thrombectomy (ET) has transformed acute ischaemic stroke (AIS) therapy in patients with large vessel occlusion (LVO). Left ventricular systolic dysfunction (LVSD) decreases global cerebral blood flow and predisposes to hypoperfusion. We evaluated the relationship between LVSD as measured by LVEF, and clinical outcomes in patients with anterior cerebral circulation LVO who undergo ET. Methods: This retrospective study examined patients from our AIS endovascular thrombectomy registry from 2013-2018. We included all consecutive patients who had anterior circulation LVO (ICA, M1, M2) who underwent ET, and had transthoracic two-dimensional echocardiography. LVSD was measured by assessment of the LVEF using Simpson’s biplane method of discs according to American Society of Echocardiography guidelines. LVSD was defined as a reduced LVEF of <50%. Primary outcome was defined as good functional outcome using a modified Rankin Scale (mRS) of 0-2 at 3-months. Results: Of 254 AIS patients with anterior circulation LVO, we included 229 patients with complete echocardiography assessment. On multivariate analyses, older age, diabetes mellitus, lower ASPECTS, unsuccessful recanalization, smaller LV outflow tract diameter and LVSD were significantly associated with poor functional outcomes (Table 1). On ordinal (shift) analyses, LVSD was associated with an unfavourable shift in the mRS outcomes (OR 3.09, 95% CI 1.68 - 5.69, p < 0.001) after adjusting for age and ischemic heart disease (Figure). Conclusion: Anterior circulation LVO AIS patients with LVSD have poorer outcomes after ET, suggesting the need to tailor peri-procedural management strategies.

Cardiotrophin-1 (CT-1) is a cytokine that has been implicated as a factor involved in myocardial remodelling. The objective of the present study was to establish the relationship between circulating levels of CT-1 and measures of left ventricular size and systolic function in patients with heart failure. We recruited 15 normal subjects [six male; median age 60 years (range 30–79 years)] and 15 patients [11 male; median age 66 years (range 43–84 years)] with a clinical diagnosis of heart failure and echocardiographic left ventricular systolic dysfunction (LVSD). Echocardiographic variables (left ventricular wall motion index, end-diastolic and -systolic volumes, stroke volume, fractional shortening) and plasma CT-1 levels were determined. In patients with LVSD [median wall motion index 0.6 (range 0.3–1.4)], CT-1 was elevated [median 110.4 fmol/ml (range 33–516 fmol/ml)] compared with controls [wall motion index 2 in all cases; median CT-1 level 34.2 fmol/ml (range 6.9–54.1 fmol/ml); P < 0.0001]. Log CT-1 was correlated with log wall motion index (r = -0.76, P < 0.0001), log left ventricular end-systolic volume (r = 0.54, P < 0.05), stroke volume (r = -0.60, P = 0.007) and log fractional shortening (r = -0.70, P = 0.001). In a multivariate model of the predictors of log wall motion index, the only significant predictor was log CT-1 (R2 = 56%, P = 0.006). This is the first assessment of the relationship between plasma CT-1 levels and the degree of LVSD in humans, and demonstrates that CT-1 is elevated in heart failure in relation to the severity of LVSD.
