Currently, a high carbohydrate/low fat diet is recommended for patients with heart failure and/or hypertension; however, the potentially important role that the composition of dietary fat and carbohydrate might play in the development of LVH and heart failure has not been well characterized. Recent
The effects of dietary fat intake on the development of left ventricular hypertrophy and accompanying structural and molecular remodeling in response to hypertension are not understood. The present study compared the effects of a high-fat versus a low-fat diet on development of left ventricular
The effect and possible mechanisms of action of aminoguanidine (a preferential iNOS inhibitor) has been studied on cardiovascular damages and overproduction of reactive nitrogen species in streptozotocin-induced diabetic rats.
METHODS
40 rats were divided into five groups (control and diabetic, with
In three models of cardiac hypertrophy the significance of catecholamines and the adenylate cyclase-cyclic AMP-system was examined. Two approaches were utilized: 1. The time course of cyclic AMP alterations was correlated with the changes in adenine nucleotide and protein biosynthesis. 2. The effect
The embryonic phenotype transformation of cardiomyocytes is an important characteristic of pathological cardiac hypertrophy. It includes transcriptional reprogramming of gene expression, a switch from lipid metabolism to carbohydrate metabolism, and a shift from α-myosin heavy chain (MHC) to fetal
Male and female rats were used to investigate the effects of type of dietary carbohydrate (CHO), copper, and ethanol consumption on lung antioxidant enzyme activities and levels of phosphorylated compounds in whole blood. Copper-deficient female rats exhibited a greater degree of copper deficiency
In myocardial hypertrophy activity of hexokinase was decreased in heart mitochondria and increased in the supernatant obtained after precipitation of the mitochondria. Activities of phosphofructokinase and fructose diphosphate aldolase were decreased within the acute period of hyperfunction and
Previous studies reported that diets high in simple carbohydrates could increase blood pressure in rodents. We hypothesized that the converse, a low-carbohydrate/high-fat diet, might reduce blood pressure. Six-week-old spontaneously hypertensive rats (SHR; n = 54) and Wistar-Kyoto rats (WKY; n = 53,
Administration of coenzyme Q10 to humans and animals has a beneficial effect on a number of cardiac diseases. The purpose of the present study was to determine if coenzyme Q10 treatment could ameliorate cardiac abnormalities associated with the carbohydrate x copper interaction in rats. Weanling
A 56-year-old man, tentatively diagnosed as having cardiomegaly, was found to have a large cyst in the left anterior mediastinum. At thoracotomy a multilocular cystic mass containing a colorless serous fluid was found and resected. Histologically, the cyst was lined with flattened epithelial cells,
Carbohydrates (CHO) such as fructose (FR) or sucrose, but not starch (ST), aggravate the consequences of dietary copper (Cu) deficiency in rats. To evaluate whether this Cu X CHO interaction is pertinent to human health, the pig was used as an animal model. In two studies, 66 weanling pigs were fed
Several studies have demonstrated that overnutrition during early postnatal period can increase the long-term risk of developing obesity and cardiac disorders, yet the short-term effects of postnatal overfeeding in cardiac metabolism remains unknown. The aim of our study was to investigate the
1. Metabolic remodelling in the heart occurs in response to chronically altered workload and substrate availability. Recently, the importance of the metabolic remodelling processes inherent in the hypertrophic growth response (whether primary or secondary) has been recognized. 2. Altered energy
BACKGROUND
Chronic hypertension leads to cardiac hypertrophy, heart failure, and premature death. Little is known about the impact of dietary macronutrient composition on hypertension-induced cardiac hypertrophy and mortality. We investigated the effects of consuming either a high complex
1. Alterations in myocardial energy metabolism accompany pressure overload-induced hypertrophy. We previously described a novel model of catecholamine-induced hypertrophy in which A/J mice exhibit more robust cardiac hypertrophy than B6 mice. Accordingly, we assessed the influence of mouse strain on
