[Cardiac hypertrophy: molecular and cellular events].

Cardiac hypertrophy is one of the main ways in which cardiomyocytes respond to mechanical and neurohormonal stimuli. It enables myocytes to increase their work output, which improves cardiac pump function. However, this compensatory mechanism can become overwhelmed by biomechanical stress, thereby resulting in heart failure, which is associated with high morbidity and mortality. The complex mol...

Detection of Cardiac Hypertrophy by RVM and SVM Algorithms

The meaning of the hypertropy word is the increasing size.Heart hypertropy is symptoms of increase the thickness of the heart muscle that the left ventricular hypertrophy of them is the most common.The causes of hypertrophy heart disease are high blood pressure , aortic valve stenosis and sport activities respectively. Assessment of that by using ECG signal analysis is essential Because the ris...

Investigating the Mechanism of Hyperglycemia-Induced Fetal Cardiac Hypertrophy

Hyperglycemia in diabetic mothers enhances the risk of fetal cardiac hypertrophy during gestation. However, the mechanism of high-glucose-induced cardiac hypertrophy is not largely understood. In this study, we first demonstrated that the incidence rate of cardiac hypertrophy dramatically increased in fetuses of diabetic mothers using color ultrasound examination. In addition, human fetal cardi...

Novel molecular targets in the treatment of cardiac hypertrophy.

Left ventricular hypertrophy represents the heart's response to increased biomechanical stress such as arterial hypertension or valvular heart disease. Cardiac hypertrophy has traditionally been considered a compensatory mechanism required to normalize wall tension and to maintain cardiac output. However, recent clinical studies as well as several animal models have shown that sustained cardiac...

Hypertrophy, pathology, and molecular markers of cardiac pathogenesis.

Increased ventricular expression of several genes, including atrial natriuretic factor (ANF), has been documented in experimental models of cardiac hypertrophy. It remains to be clarified whether altered expression of these genes is a consistent marker of the hypertrophy itself or a marker of some parallel pathogenetic process. Using a transgenic mouse model of hypertrophic cardiomyopathy as a ...
