Abstract

The present study aims to study the role of receptor activator of nuclear factor kappa B ligand/receptor activator of nuclear factor kappa B/osteoprotegerin (RANKL/RANK/OPG) system in cardiac hypertrophy in a spontaneous hypertension rat (SHR) model and the effects of amlodipine and atorvastatin intervention. Thirty-six-week-old male SHRs were randomly divided into four groups: 1) SHR control group; 2) amlodipine alone (10 mg/kg/d) group, 3) atorvastatin alone (10 mg/kg/d) group, 4) combination of amlodinpine and atorvastatin (10 mg/kg/d for each) group. Same gender, weight, and age of Wistar-Kyoto (WKY) rats with normal blood pressure were used as normal control. Drugs were administered by oral gavage over 12 weeks. The thicknesses of left ventricle walls, left ventricle weight, and cardiac function were measured by transthoracic echocardiography. Left ventricular pressure and function were assessed by hemodynamic examination. Cardiomyocyte hypertrophy and collagen accumulation in cardiac tissue were measured by hematoxylin and eosin (HE) and Masson staining, respectively. The hydroxyproline content of cardiac tissue was examined by biochemistry technique. RANKL, RANK and OPG mRNA, protein expression and tissue localization we...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.

Cardiomegaly

Cardiomegaly, known as an enlarged heart, is a multifactorial disease with different pathophysiological mechanisms. Hypertension, pregnancy, exercise-induced and idiopathic causes are some mechanisms of cardiomegaly. Discover the latest research of cardiomegaly here.

Cardiac Remodeling

Cardiac remodeling in response to a myocardial infarction is characterized by progressive ventricular dilatation, cardiac hypertrophy, fibrosis, and deterioration of cardiac performance. Discover the latest research on Cardiac Remodeling here.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Cardiovascular Homeostasis

Cardiovascular regulation and homeostasis is important in maintaining health and dysfunction may lead to cardiovascular diseases. Nitric oxide and vascular endothelium are one of many molecules involved in the homeostatic mechanism. Here is the latest research on cardiovascular homeostasis.
