Nutrition and Cardiovascular Diseases: Programming and Reprogramming

Emiliana Barbosa Marques et al. Karyne Pollo de Souza Thaís Alvim-Silva Ivis Levy Fernandes Martins … Samuel Pedro Christianne Bretas Vieira Scaramello

Abstract

The Developmental Origin of Health and Disease (DOHaD) is an area of science dedicated to studying the processes by which insults during critical periods of mammals development leading to physiological changes resultig in diseases throughout life. Studies point to a complex interaction between nutritional status in early life and cardiovascular system homeostasis in which maternal malnutrition during gestation and/or lactation, as well as early weaning, are associated with development of cardiovascular diseases in adulthood. In this context, epigenetic changes, such as DNA methylation, histone acetylation, and change in microRNA expression have been considered molecular bases of cellular plasticity, which can also be gender-dependent. Experimental studies have demonstrated that interventions encompassing the consumption of functional food/bioactive compounds, as well as energetic and nutrients adjustments on the diet, may attenuate or even prevent consequences associated with plasticity of development, improving cardiovascular health. This review aimed to gather and discuss the findings within this context, published over the last ten years.

Maternal Intake of Flaxseed During Lactation and Exercise Training Protect Against Salt Overload-Induced Aortic Remodeling in Adult Offspring

Simoni Silva-Couto et al. André Manoel Correia-Santos Gabriela Câmara Vicente Caroline Luiza Codonho Castro … Vanessa de Lana Melo Barreto Joyce Eduarda Campos Martins Queila Lenzi Gilson Teles Boaventura Maurício Alves Chagas

Abstract

Background

High dietary sodium intake can induce endothelial stiffness even without changes in blood pressure.

Objectives

To evaluate the effects of exercise training and chronic intake of sodium chloride solution on aortic morphology of male offspring of rat dams who consumed flaxseed during lactation.

Methods

Female rats were fed with a control diet or a flaxseed diet during lactation. At weaning, two male offspring of each rat dam were allocated into eight groups for 180 days: four groups received a control diet e four received a flaxseed diet, with /without exercise and with/without NaCl solution supply. Aorta was collected for histomorphometric analysis. The one-way analysis of variance was used and P value < 0.05 was considered statistically significant.

Results

The chronic use of 1% NaCl solution led to changes in aortic histoarchitecture in the control group: increase in aortic intima-media thickness (10,4%, p<0.0001) and reduced number of elastic lamellae (-8,1%, p<0.0001). Groups of offspring of mother that consumed flaxseed during lactation, the chronic use of 1% NaCl alone did not lead to an increase in the aortic intima-media thickness. Exercise training of adult offspring increased aortic intima-media thickness (13.3%, p<0.0001), with preservation of elastic components and aortic flexibility.

Conclusion

Chronic salt overload caused adverse effects on the aorta of rats, and maternal consumption of the flaxseed diet during lactation protected against aortic remodeling. Int J Cardiovasc Sci. 2020; [online].ahead print, PP.0-0

Effect of Lactation on myocardial vulnerability to ischemic insult in rats

Sahar Askari et al. Alireza Imani Hamidreza Sadeghipour Mahdieh Faghihi … Zohreh Edalatyzadeh Samira Choopani Nasser Karimi Sulail Fatima

Abstract

Background:

Cardiovascular diseases are the leading cause of mortality and long-term disability worldwide. Various studies have suggested a protective effect of lactation in reducing the risk of cardiovascular diseases.

Objective:

This study was designed to assess the effects of pregnancy and lactation on the vulnerability of the myocardium to an ischemic insult.

Methods:

Eighteen female rats were randomly divided into three groups: ischemia-reperfusion (IR), in which the hearts of virgin rats underwent IR (n = 6); lactating, in which the rats nursed their pups for 3 weeks and the maternal hearts were then submitted to IR (n = 6); and non-lactating, in which the pups were separated after birth and the maternal hearts were submitted to IR (n = 6). Outcome measures included heart rate (HR), left ventricular developed pressure (LVDP), rate pressure product (RPP), ratio of the infarct size to the area at risk (IS/AAR %), and ventricular arrhythmias – premature ventricular contraction (PVC) and ventricular tachycardia (VT).

Results:

The IS/AAR was markedly decreased in the lactating group when compared with the non-lactating group (13.2 ± 2.5 versus 39.7 ± 3.5, p < 0.001) and the IR group (13.2 ± 2.5 versus 34.0 ± 4.7, p < 0.05). The evaluation of IR-induced ventricular arrhythmias indicated that the number of compound PVCs during ischemia, and the number and duration of VTs during ischemia and in the first 5 minutes of reperfusion in the non-lactating group were significantly (p < 0.05) higher than those in the lactating and IR groups.

Conclusion:

Lactation induced early-onset cardioprotective effects, while rats that were not allowed to nurse their pups were more susceptible to myocardial IR injury.
