Atriopeptins: Protection from Myocardial Hypertrophy and Heart Failure

Molecular Mechanisms of Myocardial Hypertrophy and Heart Failure

Hodgkin’s Lymphoma Presenting with Myocardial Metastasis and Heart Failure

Although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. We report a case of Hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalize...

Interferon-γ ablation exacerbates myocardial hypertrophy in diastolic heart failure.

Diastolic heart failure (HF) accounts for up to 50% of all HF admissions, with hypertension being the major cause of diastolic HF. Hypertension is characterized by left ventricular (LV) hypertrophy (LVH). Proinflammatory cytokines are increased in LVH and hypertension, but it is unknown if they mediate the progression of hypertension-induced diastolic HF. We sought to determine if interferon-γ ...

Hypertension, hypertrophy, heart failure.

Heart failure presents a number of difficulties. Its very definition has proved taxing, and the clinical diagnosis is frequently incorrect. Patients with objective abnormalities of left ventricular function are not infrequently asymptomatic, hence treatment is often delayed. Even when a firm diagnosis is secured, only a minority of patients receive optimal medical treatment. Of concern is the i...

Cardiac Hypertrophy and Heart Failure

In cardiac and skeletal muscle, the sarcoplasmic reticulum (SR) plays a central role in the contraction relaxation cycle of the muscle by virtue of its ability to regulate the intracellular free Ca'+ concentration [Ca'+],. Ca'+ release from the SR increases [Ca'+] (10`mol/L), thus inducing contraction, whereas Ca2` uptake by the SR reduces [Ca'+] (=10-7 mol/L), producing muscle relaxation. In c...
