Abstract
Background Acute stroke is an important cause of morbidity and mortality. Myocardial injury is an important complication of acute cerebrovascular events. Neurogenic stress cardiomyopathy (NSC) is a condition of acute myocardial systolic dysfunction that can be observed after acute cerebrovascular events. Objective In this study, we aimed to investigate the relationship between myocardial function assessed by two-dimensional speckle-tracking echocardiography and National Institutes of Health Stroke Scale (NIHSS) score in patients with acute ischemic stroke. Materials and Methods This cross-sectional study screened 97 patients (males, 42; females, 55; 65 ± 16 years) with acute ischemic stroke. Around 17 patients were excluded and 80 patients were studied. Patients were divided into two groups based on the calculated NIHSS score (Group 1, NIHSS score <16; Group 2, NIHSS score ≥16). Demographic, clinical, and laboratory data for all patients were collected. Cardiac function was evaluated by two-dimensional speckle tracking echocardiography within 48 h of admission to the neurology care unit. Results There were no significant differences in the demographic parameters of patients. The absolute value of global longitudinal systolic strain (GLS) was significantly higher in Group 1 patients than in Group 2 patients (21.4 ± 2.2 vs 15.9 ± 2.7, P = 0.0281). We found that thirteen patients (22%) had normal LVEF and abnormal LV GLS in Group 1 (P = 0.036). Eight patients (36%) had normal LVEF and abnormal LV GLS in Group 2 (P = 0.042). E/e', QT on ECG, and serum troponin levels were significantly higher in Group 2 patients than in Group 1 patients (P < 0.05). Conclusions Our results suggest that GLS is associated with stroke severity on admission in patients with acute ischemic stroke. GLS is an indicator of myocardial deformation with a different from LVEF. GLS can detect early myocardial dysfunction despite preserved LVEF.

From Structural to Functional Hypertension Mediated Target Organ Damage—A Long Way to Heart Failure with Preserved Ejection Fraction. J Clin Med 2022; 11:jcm11185377. [PMID: 36143024 PMCID: PMC9504592 DOI: 10.3390/jcm11185377] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 09/01/2022] [Accepted: 09/08/2022] [Indexed: 11/17/2022] Open
Abstract
Arterial hypertension (AH) is a major risk factor for the development of heart failure (HF) which represents one of the leading causes of mortality and morbidity worldwide. The chronic hemodynamic overload induced by AH is responsible for different types of functional and morphological adaptation of the cardiovascular system, defined as hypertensive mediated target organ damage (HMOD), whose identification is of fundamental importance for diagnostic and prognostic purposes. Among HMODs, left ventricular hypertrophy (LVH), coronary microvascular dysfunction (CMVD), and subclinical systolic dysfunction have been shown to play a role in the pathogenesis of HF and represent promising therapeutic targets. Furthermore, LVH represents a strong predictor of cardiovascular events in hypertensive patients, influencing per se the development of CMVD and systolic dysfunction. Clinical evidence suggests considering LVH as a diagnostic marker for HF with preserved ejection fraction (HFpEF). Several studies have also shown that microalbuminuria, a parameter of abnormal renal function, is implicated in the development of HFpEF and in predicting the prognosis of patients with HF. The present review highlights recent evidence on the main HMOD, focusing in particular on LVH, CMD, subclinical systolic dysfunction, and microalbuminuria leading to HFpEF.

Abstract
Speckle tracking echocardiography is a novel technique to quantify cardiac function and deformation. It has been applied in a series of cardiovascular diseases for the evaluation of early cardiac impairment. We recently used this technique to investigate cardiac structure and function in patients with primary aldosteronism. Cardiac damage usually occurs earlier in patients with primary aldosteronism than those with primary hypertension, probably because aldosterone hypersecretion is more commonly observed in the former than the latter patients. In this article, we will review the imaging studies, especially with speckle tracking echocardiography, for the detection of early cardiac dysfunction in primary aldosteronism as a disease model.

Abstract
Arterial hypertension represents a systemic burden, and it is responsible of various morphological, functional and tissue modifications affecting the heart and the cardiovascular system. Advanced imaging techniques, such as speckle tracking and three-dimensional echocardiography, cardiac magnetic resonance, computed tomography and PET-computed tomography, are able to identify cardiovascular injury at different stages of arterial hypertension, from subclinical alterations and overt organ damage to possible complications related to pressure overload, thus giving a precious contribution for guiding timely and appropriate management and therapy, in order to improve diagnostic accuracy and prevent disease progression. The present review focuses on the peculiarity of different advanced imaging tools to provide information about different and multiple morphological and functional aspects involved in hypertensive cardiovascular injury. This evaluation emphasizes the usefulness of the emerging multiimaging approach for a comprehensive overview of arterial hypertension induced cardiovascular damage.

Abstract
Systemic lupus erythematosus (SLE) often leads to various cardiovascular diseases. We aimed to investigate the value of peak strain dispersion (PSD) in evaluating left ventricular dysfunction in patients with uncomplicated SLE. Eighty-seven female SLE patients and fifty-nine healthy female controls were recruited. The SLE patients were divided into inactive disease (SLE disease activity index (SLEDAI) ≤ 4; n = 48) and active disease (SLEDAI ≥ 5; n = 39) subgroups. Traditional echocardiography and two-dimensional speckle-tracking echocardiography were performed using a GE VividE9 ultrasound diagnostic system and an advanced quantitative analysis EchoPAC workstation (version 201), respectively. The global longitudinal strain (GLS) in the SLE with SLEDAI ≤ 4 group was comparable to that in the control group (- 19.89% vs - 20.7%; P = 0.061). However, GLS was obviously damaged in the SLE with SLEDAI ≥ 5 group compared with that in the control group (- 19.07% vs - 20.7%; P < 0.001). PSD impairment was observed in the SLE with SLEDAI ≤ 4 group (33.83 ms vs 31.44 ms; P = 0.012) and SLE with SLEDAI ≥ 5 groups (52.31 ms vs 31.44 ms; P < 0.001), but the largest difference was observed in the active disease group. Linear regression analysis showed that PSD was moderately correlated with the SLEDAI (r = 0.535; P < 0.001) in SLE patients with SLEDAI ≤ 4 and showed the best correlation with the SLEDAI (r = 0.646; P < 0.001) in the SLE patients with SLEDAI ≥ 5. A correlation between GLS and the SLEDAI (r = 0.359; P = 0.025) was found in the active disease group but not in the inactive disease group (r = 0.253; P = 0.082). PSD is more comprehensive and accurate for evaluating left ventricular subclinical dysfunction in SLE patients. In inactive SLE patients, PSD is a more sensitive index to evaluate early systolic dysfunction of the left ventricle. GLS may be a more vulnerable indicator of early left ventricular cardiac dysfunction in active SLE patients. Controlling disease activity may reduce the events of cardiac dysfunction.

Abstract
Background Fetuses of diabetic mothers develop left ventricular (LV) hypertrophy and are at increased long-term risk of cardiovascular disease. In our previous longitudinal study from midgestation to late infancy we showed persistence of LV hypertrophy and increased aortic stiffness compared with infants of healthy mothers, the latter of which correlated with third trimester maternal hemoglobin A1c. In the present study, we reexamined the same cohort in early childhood to determine if these cardiovascular abnormalities persisted. Methods Height, weight, and right arm blood pressure were recorded. A full functional and structural echocardiogram was performed with offline analysis of LV posterior wall and interventricular septal diastolic thickness (IVSd), systolic and diastolic function, and aortic pulse wave velocity. Vascular reactivity was assessed using digital thermal monitoring. Participants also completed a physical activity questionnaire. Results Twenty-five children of diabetic mothers (CDMs) and 20 children from healthy pregnancies (mean age, 5.6 ± 1.7 and 5.3 ± 1.3 years, respectively; P = not significant) were assessed. Compared with controls, IVSd z score was increased in CDMs (1.2 ± 0.6 vs 0.5 ± 0.3, respectively; P = 0.006), with one-fifth having a z score of more than +2.0. Aortic pulse wave velocity was increased in CDMs (3.2 ± 0.6 m/s vs 2.2 ± 0.4 m/s; P = 0.001), and correlated with IVSd z score (R2 = 0.81; P = 0.001) and third trimester maternal A1c (R2 = 0.65; P < 0.0001). Body surface area, height, weight, blood pressure, vascular reactivity, and physical activity scores did not differ between groups. Our longitudinal analysis showed that individuals with greater IVSd, and aortic stiffness in utero, early and late infancy also tended to have greater measures in early childhood (P < 0.001 and P < 0.0001, respectively). Conclusions CDMs show persistently increased interventricular septal thickness and aortic stiffness in early childhood.

Abstract
Heart failure with preserved ejection fraction (HFpEF) has recently been recognized as the single greatest unmet need in cardiovascular medicine. As the population ages and the comorbidity increases, the prevalence of HFpEF increases considerably. Even though there have been large numbers of studies on pathophysiology, diagnosis, and treatment of HFpEF for latest years, there are no current pharmacologic interventions that can reduce mortality. HFpEF is currently understood as a heterogeneous syndrome originated from the interplay of cardiac and extracardiac abnormalities recognized by systemic inflammation, endothelial and coronary microvascular dysfunction, cardiomyocyte dysfunction and skeletal muscle dysfunction. The difficult “jigsaw puzzle” called HFpEF has been filled with some pieces, but it is still not enough to meet clinical needs. Here, we review recent evidences and unsolved problems about HFpEF to improve our understanding of HFpEF. Finally, we hope to accelerate to completion of the problematic “jigsaw puzzle”.

Left atrial mechanics and aortic stiffness following high intensity interval training: a randomised controlled study. Eur J Appl Physiol 2020; 120:1855-1864.

Abstract
PURPOSE High intensity interval training (HIIT) has been shown to improve important health parameters, including aerobic capacity, blood pressure, cardiac autonomic modulation and left ventricular (LV) mechanics. However, adaptations in left atrial (LA) mechanics and aortic stiffness remain unclear. METHODS Forty-one physically inactive males and females were recruited. Participants were randomised to either a 4-week HIIT intervention (n = 21) or 4-week control period (n = 20). The HIIT protocol consisted of 3 × 30-s maximal cycle ergometer sprints with a resistance of 7.5% body weight, interspersed with 2-min of active unloaded recovery, three times per week. Speckle tracking imaging of the LA and M-Mode tracing of the aorta was performed pre and post HIIT and control period. RESULTS Following HIIT, there was significant improvement in LA mechanics, including LA reservoir (13.9 ± 13.4%, p = 0.033), LA conduit (8.9 ± 11.2%, p = 0.023) and LA contractile (5 ± 4.5%, p = 0.044) mechanics compared to the control condition. In addition, aortic distensibility (2.1 ± 2.7 cm2 dyn-1 103, p = 0.031) and aortic stiffness index (- 2.6 ± 4.6, p = 0.041) were improved compared to the control condition. In stepwise linear regression analysis, aortic distensibility change was significantly associated with LA stiffness change R2 of 0.613 (p = 0.002). CONCLUSION A short-term programme of HIIT was associated with a significant improvement in LA mechanics and aortic stiffness. These adaptations may have important health implications and contribute to the improved LV diastolic and systolic mechanics, aerobic capacity and blood pressure previously documented following HIIT.

Abstract
Background This study was performed to compare the associations of brachial-ankle pulse wave velocity (baPWV) and central blood pressure (CBP) measurements with left ventricular (LV) geometry and diastolic function. Methods A total of 77 subjects (64.5 ± 10.8 years, 67.5% females) without documented cardiovascular disease were prospectively recruited. All subjects underwent transthoracic echocardiography, baPWV and noninvasive measurement of CBP on the same day. Results In simple linear correlation analyses, neither baPWV nor CBP was associated with LV mass index or relative wall thickness (P > 0.05 for each). Although baPWV significantly correlated with septal e´ velocity in simple linear correlation analyses (r = 0.258, P = 0.025), the significance was lost after controlling for potential confounder (P = 0.881). In simple linear correlation analyses, central systolic blood pressure (CSBP) and central pulse pressure (CPP) significantly correlated with both septal e´ velocity or E/e´ (P < 0.05 for each); however, neither central diastolic nor mean arterial pressures was associated with both septal e´ velocity and E/e´ (P > 0.05 for each). After controlling for confounders, including age, sex and body mass index, CSBP correlated with septal e´ velocity (β = − 0.258, P = 0.025), but not with E/e´ (P = 0.074). CPP correlated with both septal e´ velocity (β = − 0.300, P = 0.014) and E/e´ (β = 0.428, P = 0.002) in the same multivariable model. Conclusions In subjects without documented cardiovascular disease, CSBP and CPP may be more strongly associated with LV diastolic function than baPWV. Further studies with a larger sample size are needed to confirm our results.

Abstract
The aim of this research is to evaluate the longitudinal and circumferential systolic function of the left ventricle with different configurations from endocardium, midmyocardium, and epicardium, respectively, in patients with uremia using layer-specific 2-dimensional speckle tracking echocardiography (2D-STE).According to the different left ventricular (LV) configurations, 119 patients with uremia were divided into 2 groups: LV normal group (LVN group, n = 63) and LV hypertrophy group (LVH group, n = 56). In all, 66 healthy volunteers were selected as controls. High-frame rate 2-dimensional images were recorded from the apical 4-chamber view, apical 2-chamber view, parasternal LV long-axis view, and mitral annulus, papillary muscle, and apical levels of the parasternal LV short-axis view during 3 consecutive cardiac cycles. The peak systolic longitudinal strain (LS) and circumferential strain (CS) were measured in the endocardium, midmyocardium, and epicardium.In the 3 groups, the endocardium had the highest LS and CS, whereas the epicardium had the lowest LS and CS; the LS and CS of each group gradually decreased from the endocardium to the epicardium in all the 3 sections; the LS and CS of the myocardial layers were kept gradient features, namely, endocardium > midmyocardium > epicardium. The LS of the endocardium in the LVN and LVH groups was significantly lower than that in the control group (P < .05). The LS of the midmyocardium and epicardium in the LVH group were significantly lower than those in the control group (P < .05). The LS of the endocardium significantly decreased in the LVH group compared with that in the LVN group (P < .05). The CS of the endocardium and midmyocardium in the LVH group significantly decreased compared with those in the control and LVN groups (P < .05). There were no significant differences in the CS between the LVN and control groups (P > .05).In patients with uremia, the longitudinal and circumferential systolic function in 3 myocardial layers of the LVH group, and the longitudinal systolic function in endocardium of the LVN group were found significantly impaired by layer-specific 2D-STE.

Abstract
This narrative review summarizes a decade of experience examining the cross-sectional and longitudinal relationships of arterial stiffness, as assessed using carotid-femoral pulse wave velocity, with outcomes in patients with chronic kidney disease enrolled in the Chronic Renal Insufficiency Cohort. Our goal is to review the importance of the pulse wave contour and pulse wave velocity and present data on the reproducibility of pulse wave velocity measurements, determinants of pulse wave velocity, and the relationship that velocity measurements have with longitudinal kidney and cardiovascular outcomes. Measures of arterial stiffness have contributed substantially to our understanding of mechanisms of cardiovascular disease, kidney disease progression, and all-cause mortality. Given the independent relationship of arterial stiffness to a variety of outcomes, it is our hope that future developments in behavioral, nutritional, and pharmacologic approaches to vascular destiffening will provide interventions that benefit patients with chronic kidney diseases.

Abstract
BACKGROUND Arterial elastance to left ventricular elastance ratio assessed by echocardiography is widely used as a marker of ventricular-arterial coupling. MATERIALS AND METHODS We investigated whether the ratio of carotid-femoral pulse wave velocity, as a marker of arterial stiffness, to global longitudinal strain, as a marker of left ventricular performance, could be better associated with vascular and cardiac damage than the established arterial elastance/left ventricular elastance index. In 299 newly-diagnosed untreated hypertensives we measured, carotid-femoral pulse wave velocity, and carotid intima-media thickness, coronary-flow reserve, arterial elastance/left ventricular elastance, global longitudinal strain, and markers of left ventricular diastolic function (E/A and E') by echocardiography. RESULTS Pulse wave velocity-to-global longitudinal strain ratio (PWV/GLS) was lower in hypertensives than controls (-0.61 ± 0.21 vs -0.45 ± 0.11 m/sec%, P < 0.001). Low PWV/GLS values were associated with carotid-intima media thickness > 0.9 mm (P = 0.003), E/A ≤ 0.8 (P = 0.019) and E' ≤ 9 cm/sec (P = 0.002) and coronary-flow reserve < 2.5 (P = 0.017), after adjustment for age, sex and mean arterial pressure. Low PWV/GLS was also associated with increased left ventricular mass and left atrial volume in the univariate (P = 0.003 and 0.038) but not in the multivariate model. In hypertensives, there was no significant association of arterial elastance-to-left ventricular elastance index with carotid intima media thickness, coronary flow reserve, E/A, E', or left atrial volume with the exception of an inverse association with left ventricular mass (P = 0.027). CONCLUSIONS Pulse wave velocity-to-global longitudinal strain ratio but not the echocardiography-derived arterial elastance-to left ventricular elastance index is related to impaired carotid-intima media thickness, coronary-flow reserve and diastolic function in hypertensives.

Association of the plasma aldosterone concentration, left atrial deformation and ambulatory blood pressure in never-treated early hypertensive patients. Clin Exp Hypertens 2018; 41:651-656.

Abstract
Left atrial (LA) strain is known to exhibit an early progressive reduction in hypertensive patients with diastolic dysfunction. However, an association of the renin-angiotensin-*aldosterone system (RAAS) with LA deformation has not been found in these patients. We aimed to investigate the association of plasma aldosterone concentration (PAC) and 24-hour ambulatory blood pressure monitoring (ABPM) with LA and left ventricle (LV) deformation in never-treated early hypertensive patients. This cross-sectional study included 101 never-treated subjects who were registered in a working group at The Catholic University of Korea. The patients were divided into a hypertension group (n = 71), which was defined as having a systolic blood pressure (BP) ≥130 mm Hg and/or a diastolic BP ≥80 mm Hg based on ABPM, and a control group (n = 30). Enrolled patients underwent conventional and speckle tracking echocardiography, ABPM, and measurement of pulse wave velocity, PAC, and plasma renin activity. Compared with the control group, the hypertension group had significantly increased PAC, global longitudinal strain (GLS), atrial reservoir strain, atrial pump strain, and atrial systolic strain rate. LA pump strain was independently associated with nighttime systolic BP. PAC was correlated with GLS but not LA deformation in hypertensive patients without clinically apparent target organ damage. The raised LV pressure secondary to the nocturnal systemic pressure overload might be more strongly associated with LA deformation than with the RAAS.

Abstract
BACKGROUND The pathogenesis of left ventricular (LV) dysfunction in diabetes has been attracting attention. It has been reported that LV longitudinal systolic myocardial function determined by speckle tracking echocardiography (STE) is associated with diabetic polyneuropathy (DPN). However, the relationship between the severity of peripheral neuropathy and LV myocardial dysfunction is unknown. This study examined the relationship between the severity of DPN and echocardiographic parameters as well as clinical features. METHODS The subjects were 166 patients (57 ± 14 years old) with diabetes who had a normal LV ejection fraction (≥ 55%). To assess LV longitudinal systolic function, global longitudinal strain (GLS) was calculated by two-dimensional STE as the average peak strain of 18 LV segments in three standard apical views. A nerve conduction study (NCS) was performed in each subject to assess the severity of neuropathy based on the NCS Baba Classification (Grade 0: no apparent abnormalities-Grade IV: abolition). Three nerves in the lower extremity were examined: tibial nerve (F-wave latency, motor nerve conduction velocity, and amplitude), sural nerve (sensory conduction velocity and amplitude), and peroneal nerve (motor nerve conduction velocity and amplitude). RESULTS Of the 166 subjects, 112 subjects (67.5%) were confirmed to have DPN, and all the subjects were divided into two groups according to the presence/absence of DPN. When multivariate analysis was performed using significant factors from univariate logistic regression analysis as explanatory variables, GLS was found to be an independent determinant of DPN (odds ratio: 0.55, p < 0.001). In multivariate analysis of NCS data, F-wave latency was the most important determinant of DPN (odds ratio: 1.43, p < 0.001). There was a significant negative correlation between F-wave latency and GLS (r = - 0.43, p < 0.001). Regarding the relation between GLS and the severity of DPN, GLS was significantly lower in patients with Grade I or higher DPN than in patients without DPN, but showed no significant difference between the grades of neuropathy. In addition, GLS was significantly lower when 2-3 lower extremity nerves were affected by DPN than in patients without DPN. CONCLUSION Patients with diabetes may already have subclinical LV myocardial dysfunction when DPN is Grade I. Assessment of LV longitudinal systolic function by GLS may be important in diabetic patients with DPN.
