Effect of food intake on left ventricular wall stress

Abstract

ObjectiveLeft ventricular wall stress has been investigated in a variety of populations, but the effect of food intake has not been evaluated. We assessed whether left ventricular wall stress is affected by food intake in healthy subjects.MethodsTwenty-three healthy subjects aged 25.6 ± 4.5 years were investigated. Meridional end-systolic wall stress (ESS) and circumferential end-systolic wall stress (cESS) were measured before, 30 minutes after, and 110 minutes after a standardised meal.ResultsBoth ESS and cESS decreased significantly (P < 0.001) from fasting values 30 minutes after the meal, and had not returned to baseline after 110 minutes. ESS decreased from 65 ± 16 kdynes/cm2 (fasting) to 44 ± 12 kdynes/cm2 30 minutes after, and to 58 ± 13 kdynes/cm2 110 minutes after eating. cESS decreased from 98 ± 24 kdynes/cm2 to 67 ± 18 kdynes/cm2 30 minutes after, and to 87 ± 19 kdynes/cm2 110 minutes after the meal.ConclusionThis study shows that left ventricular wall stress is affected by food intake in healthy subjects.

Effect of food intake on left and right ventricular systolic tissue Doppler measurements

“…Our study population has previously been evaluated in other published reports (Dencker et al ., ; Hlebowicz et al ., ,b; Gårdinger et al ., ). Nineteen healthy subjects, aged 26·2 ± 4·2 years, were investigated.…”

Effect of food intake on 92 neurological biomarkers in plasma

“…There is a continuous search for novel biomarkers that could improve the assessment in neurological diseases (Lind et al., ; Lind, Emami Khoonsari et al., ; Lind, Wu et al., ; Miclescu, Svahn, & Gordh, ; Moen et al., ). Digestion of food is known to have significant hemodynamic and metabolic effects (Dencker, Björgell, & Hlebowicz, ; Dieden, Gårdinger, Bjorgell, Hlebowicz, & Dencker, ; Gårdinger, Bjorgell, Hlebowicz, & Dencker, ; Hlebowicz, Lindstedt‐Ingemansson, Björgell, & Dencker, ; Hlebowicz, Lindstedt‐Ingemansson, Björgell, & Dencker, ; Quatela, Callister, Patterson, & MacDonald‐Wicks, ; Stensel, ), and may therefore affect different biomarkers. It is relevant from a practical point of view to investigate if these biomarkers are affected by food intake, as it would affect sample collection.…”

Effect of food intake on echocardiographic measurements in healthy elderly

“…[1][2][3][4] Digestion of food is known to alter hemodynamics, [5][6][7] and we have previously shown that both systolic and diastolic functions are affected significantly when comparing echocardiographic exams during fasting and after a meal in a young population. [8][9][10][11] Though the findings might not be of consequence for clinical evaluations in everyday practice, they suggest that the effects of food consumption should be considered, in studies, especially if the sample size is small. [8][9][10][11] The cardiovascular system changes with increasing age, both physiologically and not so rarely pathologically.…”

“…In the present study we therefore aim to investigate whether the previous findings are reproducible in an older population. [8][9][10][11] In an attempt to give a more comprehensive overview, we also added additional parameters of interest such as mitral annular plane systolic excursion (MAPSE), tricuspid annular plane systolic excursion (TAPSE), and global longitudinal strain (GLS). There are several echocardiographic measurements that reflects the same function-for example M-mode, tissue Doppler imaging (TDI),…”
