Heart failure (HF) is a syndrome defined by the lasix heart failure failure of the heart to deliver oxygen at a rate commensurate with the requirements of the metabolising tissues, despite normal filling pressures (or only lasix retard at the expense of increased filling pressures 1 secondary to an abnormality. HF is the most common cause of hospitalisation in patients over the age.2 The main manifestations of the syndrome are symptoms resulting from vascular congestion, such as lasix heart failure shortness of breath, abdominal distension, oedema formation and symptoms resulting from low systemic perfusion. HF syndrome is of relevant economic importance and in the adhere study signs lasix and creatinine and symptoms of congestion were the most frequent cause of hospital admission.1 Congestion often develops gradually before admission and many patients may have elevated left ventricular (LV) filling pressures even when congestion. Diuretic therapy, and especially loop diuretic therapy, are the usual way of managing congestion, especially in volume- overloaded patients.4 lasix heart failure The most commonly used diuretics in HF are loop diuretics, thiazides and potassium-sparing diuretics. This review focuses on the classes of diuretics, their role in cases of HF with volume overload and current approaches when treating this complex subset of patients. Class of Diuretics, loop Diuretics, loop diuretics, reversibly, inhibit the Na2Cl-K co-transporter of the thick ascending loop of Henle where one-third of filtered sodium is reabsorbed. This causes decreased sodium and chloride reabsorption and increased diuresis.5. Loop diuretics also enhance the synthesis of prostaglandins, which cause renal and venous dilatation. This explains some of the cardiac effects, such as reduction in pulmonary wedge pressure.6 However, it is important to recognise that the diuretic actions of loop diuretics may be lasix heart failure decreased by the concomitant use of non-steroidal anti-inflammatory drugs (nsaids possibly because this inhibits renal prostaglandin. Loop diuretics include furosemide, bumetanide, torsemide and ethacrynic acid. While the bioavailability of oral furosemide ranges from 40 to 80, the bioavailability of torasemide and bumetanide exceeds 80 ; so these two molecules may be more effective in treating patients suffering from.7. A well-known consequence of loop diuretic therapy is depletion of other electrolytes, such as potassium, magnesium, calcium and chloride (see Table 1). Thiazide Diuretics and Metolazone, benzothiazide diuretics inhibit the sodiumchloride transporter at the distal portion of the ascending limb and the first part of the distal tubule. They prevent maximal dilution of urine, thus increasing free water clearance and excretion of sodium and chloride through the renal tubular epithelium. The increased delivery of sodium to the collecting ducts enhances the exchange of sodium with potassium and, as a result, potassium depletion. They are less effective in patients with reduced glomerular filtration, because they exert their diuretic effects from the luminal side of the nephron. Although they are less potent than loop diuretics, they may work in synergy with them when a sequential segmental nephron blockade is achieved. Thiazides also decrease peripheral vascular resistance by a mechanism which is, at present, not well understood, lasix retard resulting in a decrease of blood pressure.8. Metolazone is not a thiazide but acts in a similar way. Metolazone is more potent than hydrochlorothiazide and retains its effectiveness even when there is severe glomerular filtration rate (GFR) reduction. Open original, open in new tab, potassium-sparing Diuretics. The potassium-sparing diuretics used for treating HF are the aldosterone receptor antagonists spironolactone and eplerenone. They act at the cortical collecting duct, in particular by reducing the absorption of sodium and water and increasing the excretion of hydrogen ions and potassium, and their action is mediated by the antagonism of the actions of mineral corticoids. Only 3 of filtered sodium is reabsorbed at the collecting duct, so this class of drugs does not have an appreciable diuretic effect. However they are often used in association with other more effective diuretics to correct or lasix retard prevent potassium deficiency. They are also significantly efficacious in reducing the deleterious effects of aldosterone on the cardiovascular system. Spironolactone is a non-selective aldosterone receptor antagonist, lasix retard and thus endocrine-related adverse effects (such as gynecomastia) are relatively common when it is used. Eplerone has greater lasix heart failure selectivity on the mineral corticoid receptor, and has fewer side effects.9. Diuretics in Chronic Heart Failure, diuretics are used to achieve and maintain euvolaemia (the patients dry weight) with the lowest possible dose. This means that the dose must be adjusted, particularly after restoration of the dry body weight, to avoid the risk of dehydration, which leads to hypotension and renal dysfunction.10 It is important that treatment with diuretics is always coupled with neuro-hormonal system blocking, in order. In general, due to their greater effectiveness, loop diuretics, such as furosemide, are the mainstay of diuretic therapy. Indeed loop diuretics produce more intense and shorter diuresis than thiazides, which results in more gentle and prolonged diuresis. They are, however, less effective in patients with reduced kidney function.10 As a general rule, doses of loop diuretics should be as low as possible, in order to maintain a euvolaemic state. Restricting the amount of sodium and water, daily weight monitoring and avoidance of nsaids are critical in preventing salt and water retention. The commonly used loop diuretics only act for a short time, so common therapy schemes require twice-daily administration, in order to avoid post-diuretic rebound sodium retention.
