Cardíac Insuficiency

Propylene glycol (PG) is a commonly used solvent for oral, intravenous, and topical pharmaceutical agents. Although PG is generally considered safe, when used in high doses or for prolonged periods, PG toxicity can occur. Reported adverse effects from PG include central nervous system (CNS) toxicity, hyperosmolarity, hemolysis, cardiac arrhythmia, seizures, agitation, and lactic acidosis. Patients at risk for toxicity include infants, those with renal or hepatic insuficiency, epilepsy, and burn patients receiving extensive dermal applications of PG containing products...

Erythropoietin (EPO), traditionally known as a hematopoietic hormone, has recently been shown to have effects beyond hematopoiesis such as prevention of neuronal and cardiac apoptosis secondary to ischemia and induction of neoangiogenesis. Patients with congestive heart failure (CHF) suffer considerable morbidity and mortality despite advances in therapy. Anemia, CHF, and chronic kidney insuficiency often coexist and interact to cause or worsen each other in the so-called cardio-renal anemia syndrome. Treatment with EPO has shown promise in such patients...

The French epidemiological data on cardiac insufficiency in the hospital environment are scarce. A register collecting 1772 patients was produced by the services of the National College of General Hospital Cardiologists (C.N.C.H.G.) during two periods: autumn 1999 (November) and spring 2000 (June). It involved completing a form for each of the first 20 patients with cardiac failure hospitalized over a month. 1011 and 761 observations from 59 and 47 centres (that is 17 and 16 observations per centre) were collected during the autumn and spring periods respectively...

Angiotensin II antagonists block the actions of angiotensin II by occupying the AT1 receptors. With this blockade there is no bradykinin increase, the angiotensin II synthetized by the cardiac chymase is also blocked, and the AT2 receptor is stimulated (antiproliferative effect). In animal experiments, losartan reverses left ventricular hypertrophy, inhibits myocardial fibrosis and diabetic glomerulosclerosis and significantly protects from vascular cerebral diseases. In humans, the efficacy of the angiotensin II antagonists and that of other antihypertensives is similar and is potentiated by the addition of a thiazide...
