Diastolic Strain(이완기 긴장)란 무엇입니까?
Diastolic Strain 이완기 긴장 - These quantities showed consistent patterns between subjects, and yielded repeatable results: the peak systolic volumetric strain (relative to end-diastolic strain) was 4. [1] No significant change in myocardial blood flow or diastolic strain was detected. [2] Cardiac magnetic resonance feature-tracking (CMR-FT) analysis offers a practical and rapid method to calculate systolic and diastolic strains from routinely acquired cine images. [3] We hypothesized that an inverse deformation gradient (DG) method calculation of diastolic strain (IDGDS) allows the FE model-based calculation of regional diastolic stiffness (material parameters; MP) in post-MI patients with DD. [4] We compared inter-field strength agreement of systolic and diastolic strain/strain rates at 1. [5] Measurements of ventricular global and diastolic strain and strain rate were performed offline with TomTec speckle tracking software. [6]이러한 양은 피험자 간에 일관된 패턴을 보여주었으며 반복 가능한 결과를 산출했습니다. 최대 수축기 체적 변형률(확장기 말 변형률에 비해)은 4였습니다. [1] 심근 혈류 또는 이완기 긴장의 유의한 변화는 감지되지 않았습니다. [2] 심장 자기 공명 특징 추적(CMR-FT) 분석은 일상적으로 획득한 영화 이미지에서 수축기 및 이완기 긴장을 계산하는 실용적이고 신속한 방법을 제공합니다. [3] 우리는 확장기 변형률(IDGDS)의 역 변형 구배(DG) 방법 계산이 DD가 있는 MI 후 환자에서 FE 모델 기반 국소 확장기 강성(재료 매개변수, MP) 계산을 허용한다고 가정했습니다.

The ratio of transmitral early filling velocity to early diastolic strain rate (E/e'sr) may be a more accurate measure of LV filling pressure then ratio of early filling pressure to early tissue velocity. [1] The strongest relation was between global longitudinal early diastolic strain rate and native T1 value (r=0. [2] When comparing MIS-C patients with normal EF (n=15) to controls, MIS-C patients had lower peak systolic strain as well as lower early diastolic strain rates. [3] Significant changes were also found in LV longitudinal early diastolic strain rate (LSRe; 1. [4] We investigated the relationship of LV longitudinal strain, LV early diastolic strain rate (SR) and left atrial (LA) reservoir strain with long-term CHD incidence in community-dwelling older adults.

[8] The effects of low-energy diet or exercise on cardiovascular function in younger adults with type 2 diabetes (DIASTOLIC) study has previously demonstrated an improvement in left ventricle peak early diastolic strain rate in response to aerobic exercise in patients with type-2 diabetes (T2D). [9] Longitudinal peak systolic strain, strain rate, and early diastolic strain rate were lower in PAH patients than in controls; peak atrial-diastolic strain rate was higher in pulmonary hypertension patients.

[24] Global and regional early diastolic strain rate (SRe) were quantified, as were parameters of systolic function. [25] In a univariate cox-regression model, radial, circumferential and longitudinal early diastolic strain rate (EDSR) and circumferential late diastolic strain rate were significantly associated with MACE. [26] Exposures were left atrial reservoir strain (primary), left ventricular longitudinal strain, left ventricular early diastolic strain rate, septal e’ velocity, and lateral e’ velocity. [27] Transthoracic echocardiography was performed to measure LV systolic (global longitudinal and circumferential strain; basal and apical rotation) and diastolic (early diastolic velocity of mitral inflow and lateral mitral annulus tissue; deceleration time and early diastolic strain rate) parameters using conventional and speckle-tracking echocardiography. [28] While in the DTG is not a promising alternative, the future role for speckle tracking–based early diastolic strain rate is unknown. [29] LV function, MD and exercise capacity were evaluated by two-dimensional speckle-tracking imaging and echocardiography at rest and during exercise, and the following parameters of LV function were recorded: LV global longitudinal strain (LVGLS), MD, early diastolic strain rate (SRe), the ratio of peak early diastolic mitral inflow and annulus velocity (E/e′), LV outflow tract gradient (LVOTG); LV functional reserve was assessed by ΔLVGLS and ΔSRe; exercise capacity was evaluated by metabolic equivalents (METs).

The ratio of transmitral early filling velocity to early diastolic strain rate (E/e'sr) may be a more accurate measure of LV filling pressure then ratio of early filling pressure to early tissue velocity. [1] RV strain was analysed by a blinded reader who manually traced epicardial and endocardial contours of the RV for determining peak global circumferential strain (RVGCS), time to peak strain, systolic and diastolic strain rate parameters. [2] The strongest relation was between global longitudinal early diastolic strain rate and native T1 value (r=0. [3] When comparing MIS-C patients with normal EF (n=15) to controls, MIS-C patients had lower peak systolic strain as well as lower early diastolic strain rates. [4] Significant changes were also found in LV longitudinal early diastolic strain rate (LSRe; 1. [5] We investigated the relationship of LV longitudinal strain, LV early diastolic strain rate (SR) and left atrial (LA) reservoir strain with long-term CHD incidence in community-dwelling older adults. [6] LV diastolic strain rates were indexed to cardiac preload as estimated by echocardiography derived diastolic filling pressures (E/e'), and correlated to peak VO2. [7] Results: Mean LV global longitudinal strain (GLS) and GLS in all apical chamber views, longitudinal peak systolic strain rate (SRS) at A3C, early diastolic strain rate (SRE) at A3C and late diastolic strain rate (SRA) at A3C in the ERP subjects were significantly lower than those in the subjects without ERP.

[13] The effects of low-energy diet or exercise on cardiovascular function in younger adults with type 2 diabetes (DIASTOLIC) study has previously demonstrated an improvement in left ventricle peak early diastolic strain rate in response to aerobic exercise in patients with type-2 diabetes (T2D). [14] Longitudinal peak systolic strain, strain rate, and early diastolic strain rate were lower in PAH patients than in controls; peak atrial-diastolic strain rate was higher in pulmonary hypertension patients. [15] The systolic strain value, systolic strain rate, and late diastolic strain rate of RVFW were not statistically significantly different between the three groups. [16] In a recent study conducted in animal models, the treatment with sacubitril-valsartan improved diastolic function in a mouse model of pressure overload-induced acute HFpEF, preserving the early diastolic strain rate and the ratio of early mitral inflow velocity to the global diastolic strain rate (E/e’SR) [5]. [17] Circumferential and longitudinal peak diastolic strain rate (PDSR) and peak diastolic velocity (PDV) were reduced in group PJ if compared to group nPJ and control group (PDSR = 1.

[21] Significant deterioration of longitudinal early diastolic strain rate (SRe) was found in patients with MVP in the region of the interventricular septum (1. [22] In addition, longitudinal peak systolic strain and diastolic strain rate by both cardiovascular magnetic resonance and echocardiography, and E/A ratio measured by echocardiography, were lower in preterm-born compared to term-born adults (P < 0. [23] Radial and circumferential strain and circumferential diastolic strain rate were higher in mid-anterior (P<0. [24] LV function and deformation, including LV global function index, LV global peak strain (PS), peak systolic strain rate (PSSR), and peak diastolic strain rate (PDSR), were compared among these groups. [25] We observed negligible deviations from ground-truth when using predicted boundaries alone, except in the case of early diastolic strain rate, providing confidence for the use of such machine learning models for rapid and reliable assessments of murine cardiac function. [26] Global systolic strain rate and early diastolic strain rate (1/s) in dialysis patients were significantly delayed than nondialysis (−0. [27] In addition, strain analysis, decreased LA expansion index (EI), ejection fraction (EF), peak atrial longitudinal strain, contraction strain, and late diastolic strain rate (A sr) and systolic strain rate (S sr) were associated with the occurrence of AF and LAVI. [28] 01), and early diastolic strain rate (3. [29] BACKGROUND The ratio of early mitral inflow velocity to early diastolic strain rate (E/e'sr) is a novel echocardiographic measure to estimate early left ventricular (LV) filling pressure. [30] The left atrial strain rate values showed a significant difference with the lower left atrial systolic strain rate and less negative (higher) early diastolic strain rate and late diastolic strain rate. [31] In addition, strain analysis, decreased LA expansion index (EI), ejection fraction (EF), peak atrial longitudinal strain, contraction strain, and late diastolic strain rate (A sr) and systolic strain rate (S sr) were associated with the occurrence of AF and LAVI. [32] Left ventricular (LV) strain and diastolic strain rates were evaluated between the rTOF patient and control groups.

[41] Using speckle-tracking echocardiography data, we examined the cross-sectional (n=3206) and longitudinal (n=1431) associations with frailty among participants who had at least 1 measure of myocardial strain, left ventricular longitudinal strain (LVLS), left ventricular early diastolic strain rate and left atrial reservoir strain, and no history of cardiovascular disease or heart failure at the time of echocardiography. [42] Blood pressure, LV mass indexes, and LV ejection fractions were comparable in both groups, while the global circumferential peak diastolic strain rate (PDSR) was lower (0. [43] Global and regional early diastolic strain rate (SRe) were quantified, as were parameters of systolic function. [44] In a univariate cox-regression model, radial, circumferential and longitudinal early diastolic strain rate (EDSR) and circumferential late diastolic strain rate were significantly associated with MACE. [45] Exposures were left atrial reservoir strain (primary), left ventricular longitudinal strain, left ventricular early diastolic strain rate, septal e’ velocity, and lateral e’ velocity. [46] 09), and RV late diastolic strain rate (p=0. [47] Transthoracic echocardiography was performed to measure LV systolic (global longitudinal and circumferential strain; basal and apical rotation) and diastolic (early diastolic velocity of mitral inflow and lateral mitral annulus tissue; deceleration time and early diastolic strain rate) parameters using conventional and speckle-tracking echocardiography. [48] While in the DTG is not a promising alternative, the future role for speckle tracking–based early diastolic strain rate is unknown. [49] LV function, MD and exercise capacity were evaluated by two-dimensional speckle-tracking imaging and echocardiography at rest and during exercise, and the following parameters of LV function were recorded: LV global longitudinal strain (LVGLS), MD, early diastolic strain rate (SRe), the ratio of peak early diastolic mitral inflow and annulus velocity (E/e′), LV outflow tract gradient (LVOTG); LV functional reserve was assessed by ΔLVGLS and ΔSRe; exercise capacity was evaluated by metabolic equivalents (METs).
