299 Plasma lipids display increased mean aliphatic chain length in human hypertensive heart disease

Increased mean aliphatic lipid chain length in left ventricular hypertrophy secondary to arterial hypertension

About 77.9 million (1 in 4) American adults have high blood pressure. High blood pressure is the primary cause of left ventricular hypertrophy (LVH), which represents a strong predictor of future heart failure and cardiovascular mortality. Previous studies have shown an altered metabolic profile in hypertensive patients with LVH. The goal of this study was to identify blood metabolomic LVH biom...

Is plasma cardiotrophin-1 a marker of hypertensive heart disease?

OBJECTIVE This study was designed to investigate whether plasma concentration of cardiotrophin-1 (CT-1), a cytokine that induces cardiomyocyte hypertrophy and stimulates cardiac fibroblasts, is related to hypertensive heart disease, as defined by the presence of echocardiographically assessed left ventricular hypertrophy (LVH). METHODS The study was performed in 31 normotensive subjects and 1...

Autophagy in hypertensive heart disease.

In response to hypertension, the heart manifests robust hypertrophic growth, which offsets load-induced elevations in wall stress. If sustained, this hypertrophic response is a major risk factor for systolic dysfunction and heart failure. Extensive research efforts have focused on the progression from hypertrophy to failure; however, precise understanding of underlying mechanisms remains elusiv...

Cardioreparation in hypertensive heart disease.

The normal myocardium is composed of a variety of cells. Cardiac myocytes, tethered within an extracellular matrix of fibrillar collagen, represent one third of all cells; noncardiomyocytes account for the remaining two thirds. Ventricular hypertrophy involves myocyte growth. Hypertensive heart disease (HHD) includes myocyte and nonmyocyte growth that leads to an adverse structural remodeling o...
