- Glossary of Terms. Cardiac Hypertrophy. Cardiac hypertrophy is a thickening of the heart muscle (myocardium) which results in a decrease in size of the chamber of the heart, including the left and right ventricles. A common cause of cardiac hypertrophy is high blood pressure (hypertension) and heart valve stenosis.

- During right ventricular (RV) diastole, the pressure within the RV is between 0-5 mm Hg. Elasticity and compliance of the ventricular myocardium help generate a lower intraventricular pressure. Lower intraventricular pressure, aided by atrial systole, causes blood to flow across the open atrioventricular AV valve.

Hypertensive emergency Hypertensive emergency pathophysiology includes: 1  Abrupt increase in systemic vascular resistance, likely related to humoral vasoconstrictors. 2  Endothelial injury. 3  Fibrinoid necrosis of the arterioles. 4  Deposition of platelets and fibrin. 5  Breakdown of normal autoregulatory function.

Left Ventricular Hypertrophy Several underlying conditions can contribute to or influence the enlargement of the heart muscle in the left ventricle. Hypertension is the most common cause, setting the stage for left ventricular hypertrophy once a person’s blood pressure exceeds the normal level of 140/90 mm Hg. Aside from hypertension, the condition known as aortic valve stenosis is also a common cause of the hypertrophic changes in the heart.

Hypertrophic cardiomyopathy is a disease of the heart muscle. It can cause sudden death, particularly in young, active men. Medicines can prevent a fatal outcome. Further research is being carried out in the search for better treatments.

- The chronic exposure to fluid overload and hypertension may lead to cardiac stiffness and left ventricular hypertrophy; some studies have reported an increased risk of death due to inadequate total body fluid removal. Therefore, fluid management should be based on accurate estimation of patients’ dialysis needs.

- Patient Information. Left Ventricular Hypertrophy on ECG. Left ventricular hypertrophy (LVH) means that the muscle of the left pumping chamber of the heart (left ventricle) is thickened. The left ventricle's job is to pump blood to the body, and conditions that increase the work the left ventricle has to do can lead to thickening of the muscle.

Hypertrophic cardiomyopathy Hypertrophic cardiomyopathy. Hypertrophic cardiomyopathy (HCM) is an inherited disease of your heart muscle, where the muscle wall of your heart becomes thickened. HCM is a genetic condition caused by a change or mutation in one or more genes and is passed on through families. Each child of someone with HCM has a 50 per cent chance of inheriting the condition.

Hypertrophy Forensic post-mortem examination of a case of hypertrophic cardiomyopathy, showing thickening of the cardiac muscle. Hypertrophy (IPA /haɪˈpɝːtrəfi/, from Greek ὑπέρ excess + τροφή nourishment) is the increase in the volume of an organ or tissue due to the enlargement of its component cells. It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number.

Right ventricular hypertrophy Right ventricular hypertrophy. Description, Causes and Risk Factors: Abbreviation: RVH. Right ventricular hypertrophy is the increase or the enlargement in the size of the right ventricle of the heart. The right ventricle is responsible for pumping blood towards the lungs. In the lungs, blood is mixed with oxygen and then pumped back to the left ventricle to be eventually distributed to the brain and to other parts of the body. There are several possible causes of right ventricular hypertrophy.
