Heart disease, congestive

Arylidene thioxanthenes, for example, 580, prepared by the Pd(0) coupling of 9-bromomethylenethioxanthene and 3-aminophenylboronic acid, are useful for treating congestive heart disease, hypertension, and inflammatory diseases (Equation 203) <2005W02005/066153>. 

Cardiovascular Disease. Patients with systemic hypertension, arteriosclerosis, and other cardiovascular diseases may be at risk when high concentrations of topically administered adrenergic agonists such as phenylephrine are used. Repeated topical doses or soaked cotton pledgets placed in the conjunctival sac have been associated with adverse cardiovascular effects. Likewise, P-blockers should be avoided or used cautiously in patients with congestive heart disease, severe bradycardia, and high-grade atrioventricular block. Topical P-blockers, however, may be used safely in patients with cardiac pacemakers.

In moderate consumers of cobalt-doped beer, thyroid dysfunction and nonfatal congestive heart disease were observed. The number of cases fell to zero when the product was removed from the market (Alexander 1972, Achenbach etal. 1974, Burch et al. 1973, Morin and Cote 1972). 

In the UK system, where money in the system is invisible , the same pressures do not apply. This may, in part, account for some of the reluctance of UK health commissioners to embrace DM. However, in the USA, DM systems are commonplace, e.g. for the treatment of congestive heart disease and asthma, for which some 470000 Americans find themselves admitted to hospital for treatment each year. 

Cardiomyopathy. Cardiomyopathy, or diseased heart muscle, may reach a point at which the heart can no longer function. It arises from a combination of factors, including hypertension, arrhythmias, and valve disease. Other problems, such as congestive heart failure, cause the interrelated heart—lung system to break down. Because the heart can no longer adequately pump, duid builds up in the lungs and other areas. 

Nitroglycerin remains the dmg of choice for treatment of angina pectoris. It has also been found useful for the treatment of congestive heart failure, myocardial infarction, peripheral vascular disease, such as Raynaud s disease, and mitral insufficiency, although the benefits of nitroglycerin in mitral insufficiency have been questioned. 

Under certain circumstances, and very rarely, the inhibition of gluconeogenesis by metformin may suppress lactic acid metabolism and precipitate a potentially fatal lactic acidosis. Impairment of renal function, liver disease, alcoholism, conditions that give rise to increased lactate production (e.g. congestive heart failure, infections) are therefore contraindications for the application of metformin. 

The use of V2 antagonists is promising in the treatment of the hyponatremia that usually accompanies congestive heart failure and cirrhosis, two edematous conditions in which the use of diuretics is indicated. In addition, V2 antagonists may be beneficial in the treatment of polycystic kidney disease. 

ACE inhibitors do not completely block aldosterone synthesis. Since this steroid hormone is a potent inducer of fibrosis in the heart, specific antagonists, such as spironolactone and eplerenone, have recently been very successfully used in clinical trials in addition to ACE inhibitors to treat congestive heart failure [5]. Formerly, these drugs have only been applied as potassium-saving diuretics in oedematous diseases, hypertension, and hypokalemia as well as in primary hyperaldosteronism. Possible side effects of aldosterone antagonists include hyperkalemia and, in case of spironolactone, which is less specific for the mineralocorticoid receptor than eplerenone, also antiandrogenic and progestational actions. 

Several nonpeptidic, orally active vasopressin receptor antagonists have been developed. The dual V1A/V2R antagonist conivaptan is used in the treatment of hyponatraemia and could also become useful for diseases such as congestive heart failure, in which increased peripheral resistance and dilutional hyponatremia both are present [4]. Side effects of conivaptan include headache, injection site reactions, vomiting, diarrhoea, constipation and thirst. 

Labetalol is used in the treatment of hypertension, either alone or in combination with another drag such as a diuretic. Carvedilol is used to treat essential hypertension and in congestive heart failure to reduce progression of the disease. 

If the drug is given is given to treat congestive heart failure (ie, carvedilol), the patient is assessed for evidence of the disease, such as dyspnea (especially on exertion), peripheral edema, distended neck veins, and cough. 

The MAOI antidepressant drag s are contraindicated in patients widi known hypersensitivity to die drug s, liver and kidney disease, cerebrovascular disease, hypertension, or congestive heart failure and in die elderly. These drag s are given cautiously to patients witii impaired liver function, history of seizures, parkinsonian symptoms, diabetes, or hyperthyroidism.
