“…This is in line with results from another retrospective single-center study on 616 cryptogenic stroke patients [92]. In a recent small prospective single-center study with 56 cryptogenic stroke patients who had a cardiac monitor implanted for AF monitoring, low left atrial strain predicted incident AF independent of classical parameters of diastolic dysfunction, global longitudinal LV strain and cardiovascular risk factors [93]. Low atrial strain has further been shown to correspond with atrial fibrosis detected on cardiac MRI and might therefore be a good surrogate parameter for atrial remodeling [94,95].…”

Purpose of Review Cardiac imaging after ischemic stroke or transient ischemic attack (TIA) is used to identify potential sources of cardioembolism, to classify stroke etiology leading to changes in secondary stroke prevention, and to detect frequent comorbidities. This article summarizes the latest research on this topic and provides an approach to clinical practice to use cardiac imaging after stroke. Recent Findings Echocardiography remains the primary imaging method for cardiac work-up after stroke. Recent echocardiography studies further demonstrated promising results regarding the prediction of non-permanent atrial fibrillation after ischemic stroke. Cardiac magnetic resonance imaging and computed tomography have been tested for their diagnostic value, in particular in patients with cryptogenic stroke, and can be considered as second line methods, providing complementary information in selected stroke patients. Summary Cardiac imaging after ischemic stroke or TIA reveals a potential causal condition in a subset of patients. Whether systematic application of cardiac imaging improves outcome after stroke remains to be established.

Expert opinion paper on cardiac imaging after ischemic stroke

et al. 2021

This expert opinion paper on cardiac imaging after acute ischemic stroke or transient ischemic attack (TIA) includes a statement of the “Heart and Brain” consortium of the German Cardiac Society and the German Stroke Society. The Stroke Unit-Commission of the German Stroke Society and the German Atrial Fibrillation NETwork (AFNET) endorsed this paper. Cardiac imaging is a key component of etiological work-up after stroke. Enhanced echocardiographic tools, constantly improving cardiac computer tomography (CT) as well as cardiac magnetic resonance imaging (MRI) offer comprehensive non- or less-invasive cardiac evaluation at the expense of increased costs and/or radiation exposure. Certain imaging findings usually lead to a change in medical secondary stroke prevention or may influence medical treatment. However, there is no proof from a randomized controlled trial (RCT) that the choice of the imaging method influences the prognosis of stroke patients. Summarizing present knowledge, the German Heart and Brain consortium proposes an interdisciplinary, staged standard diagnostic scheme for the detection of risk factors of cardio-embolic stroke. This expert opinion paper aims to give practical advice to physicians who are involved in stroke care. In line with the nature of an expert opinion paper, labeling of classes of recommendations is not provided, since many statements are based on expert opinion, reported case series, and clinical experience.

“…Therefore, it seems natural to associate LAScd and LASct with the parameters of both mitral in ow and LV myocardial velocities (especially LAScd with E and E' velocity, LASct with A and A' velocity, and both LAScd and LASct with E/A ratio) [21]. Olsen et al's study of patients with cryptogenic stroke revealed that those with impaired LASr < 28.2% have more reduced e'value and increased E/e' ratio compared to subjects with LASr ≥ 28.2% [22]. No previous studies have con rmed the relations we found among patients with mild hypertension and without any other comorbidities.…”

BackgroundEven in patients with well-controlled arterial hypertension (AH) and without significant comorbidities left ventricular (LV) and left atrial (LA) strain abnormalities may sometimes be found in speckle-tracking echocardiography. Therefore, the aim of this study was to investigate the correlation between LA strain and LV diastolic and systolic function in a group of patients with treated, well-controlled AH.Methods LA contractile, conduit, and reservoir function, together with echocardiographic signs of LV diastolic function and LV global longitudinal strain (LV GLS), were assessed in 101 patients with treated, well-controlled AH who met the standard criteria of normal LV ejection fraction (LVEF) and normal LV diastolic function.ResultA relevant percentage of study participants presented lower than reference LV and LA strain values. Moreover, there were statistically significant differences in LA longitudinal strain (LAS) values (LAS during reservoir phase—LASr (p<0.001) and LAS during conduit phase—LAScd (p = 0.008)) between patients with high and lower LV GLS, confirmed by significant correlations between LASr, LAScd, and GLS. In the correlations analysis between LAS values and LV diastolic function parameters, statistical significance was obtained for the following: LASct (contraction) vs. e’avg, LASct vs. E/A, LASct vs. A, LAScd vs. e’avg, LAScd vs. E/A, and LAScd vs. A. Conclusions LV and LA strain abnormalities occurred within a significant percentage of patients with treated, well-controlledAH. Impaired LA strain is associated with lower LV strain and reduced LV diastolic function parameters, reflecting both the passive and active properties of the LA.
