Congestive heart failure (CHF) is typically associated with impaired left ventricular (LV) systolic performance. Few reports exist describing the long-term outcome in patients with CHF and normal LV systolic function. Fifty-two patients initially hospitalized with CHF and intact LV function (ejection fraction greater than or equal to 45%) were followed for 7 years. Mean age when initially identified was 71 +/- 11 years (range 36 to 96), and average LV ejection fraction was 61 +/- 11%. CHF was graded by a clinicoradiographic index, with a mean of 7.0 +/- 2.3 (range 3 to 12, 13 indicates worst CHF). A third heart sound was present in 19 patients (37%), and 17 (33%) had presented with acute pulmonary edema. Principal cardiovascular diagnoses were coronary artery disease in 27 (52%), hypertensive heart disease in 16 (31%) and restrictive cardiomyopathy in 7 (13%). At 7 years, cardiovascular mortality was 46% (24 of 52), and noncardiovascular mortality was 10% (5 of 52). Survival was not correlated with age, principal diagnosis, third heart sound, pulmonary edema at presentation, LV ejection fraction, or presence or degree of LV diastolic dysfunction. Cardiovascular morbidity, consisting of nonfatal recurrent CHF, myocardial infarction, unstable angina or other cardiovascular events occurred in 29% (15 of 52). Combined cardiovascular mortality and morbidity was 75% (39 of 52). In patients with CHF, intact LV systolic function does not confer the same favorable prognosis it defines in other clinical situations. For such patients, the risk of future cardiovascular events is high, a finding that should be considered when designing therapeutic strategies in this group.

We report here two cases in which patients fell into pulmonary edema due to ischemic mitral regurgitation (ischemic MR) after cardiac catheterization and underwent emergency coronary artery bypass grafting (CABG) using an intra-aortic balloon pumping. The patient were a 65-year-old man and a 80-year-old woman, and both had a chief complaint of angina after myocardiac infarction. In both cases, coronary angiography revealed triple vessel disease, and left ventriculography showed severe MR. However echocardiography, when they were hospitalized, did not show significant MR. Therefore we thought that they had gone into congestive heart failure because cardiac ischemia and volume load following cardiac catheterization provoked MR. In fact, postoperative left ventriculography and echocardiography showed decreased MR. We now think that it is important to keep in mind the cases of severe ischemic MR for which CABG alone is adequate treatment and to evaluate ischemic MR not only by left ventriculography but also by echocardiography.

Thorough assessment of the patient and good understanding of potential complications enhance patient care and safety. Correction of volume depletion and maintenance of a strict fluid balance chart is essential to avoid complications of congestive cardiac failure, cerebral or pulmonary oedema, renal failure and further dehydration. Careful monitoring of electrolytes and administration of supplements should be undertaken to prevent instability. Regular monitoring of blood glucose levels and careful insulin administration should be undertaken to prevent fluctuations in blood glucose levels. Any possible source of infection should be identified and treated as prescribed. Good basic nursing care for the patient and support and counselling for the patient and his family are essential components of holistic care.

The combined effects of negative intrathoracic pressure swings during obstructive sleep apnoeas (OSAs) and increased sympathetic nervous system tone associated with hypoxia and sleep arousal may lead to pulmonary oedema or left-ventricular hypertrophy. Therefore, we have done a study of patients with congestive heart failure secondary to idiopathic dilated cardiomyopathy to see whether OSA could contribute to impaired left-ventricular function and to assess nasal continuous positive airway pressure (NCPAP) for treatment. Eight men (aged 29-69 years) took part in the study; all were obese. Left-ventricular ejection fraction (LVEF) was measured while on stable medication and then 4 weeks after the start of nocturnal NCPAP. NCPAP was associated with abolition of OSA (mean [SE] number of apnoeas and hypopnoeas per hour of sleep 54.1 [7.2] and 1.0 [0.4] for pretreatment and NCPAP nights, respectively, p less than 0.0001). Mean (SE) LVEF increased from 37 (4)% pretreatment to 49 (5)% after four weeks' NCPAP therapy (p less than 0.0001). Withdrawal of NCPAP for 1 week in four patients was associated with a reduction in LVEF from 53 (6)% to 45 (5)% (p less than 0.001). OSA may contribute to impaired left-ventricular function in some patients with dilated cardiomyopathy of otherwise unknown origin, and reversal of OSA by NCPAP can lead to significant improvement in LVEF.

Diuretics, together with digitalis glycosides and vasodilators are of prime importance in the medical treatment of patients with congestive heart failure (CHF). Diuretics provide quick symptomatic relief in these patients. Their beneficial effect is related to the promotion of sodium and water excretion via the kidney, thus reducing extracellular fluid volume expansion and mitigating the increase in preload and afterload caused by sodium and water retention. Loop diuretics administered intravenously are indispensable in the management of pulmonary oedema; thiazides and loop diuretics in low doses are effectively used in the oral treatment of mild to moderate heart failure. Torasemide is a new loop diuretic which differs from furosemide (frusemide) and related loop diuretics by virtue of its longer elimination half-life and longer duration of action, with almost complete bioavailability. The efficacy and tolerability of torasemide have been compared with furosemide in several studies. Once daily oral administration of torasemide (starting with 5mg) or furosemide 40mg reduce bodyweight, oedema and symptoms of heart failure to a similar extent. Mean New York Heart Association class is consistently reduced by 0.5 to 0.7. Intravenous administration attenuates the increase in intracardiac pressures during exercise in patients with CHF, and produces acute improvements in cardiac haemodynamics in patients with high grade left heart failure. A beneficial effect on both pulmonary and cardiac haemodynamics has been demonstrated during chronic oral treatment of patients with previously untreated CHF. Torasemide was well tolerated with only mild and transient adverse effects reported in a small number of patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Cardiac diseases of cattle may involve valvular structures, myocardium, pericardium, or blood vessels and are manifested by the clinical signs of cardiac dysrhythmias, cardiac murmurs, generalized edema, muffled heart sounds, jugular venous distention, jugular venous pulsations, pulmonary edema, pleural effusion, or ascites. Digoxin, quinidine, and furosemide can be used effectively to control signs of CHF and cardiac arrhythmias. Combination antimicrobial therapy can be successful for cows with infective endocarditis and thrombophlebitis. Pericardial fluid drainage may temporarily improve cattle with traumatic pericarditis or lymphosarcoma so that short-term goals may be reached.

Poisoning is a significant problem in the elderly. The majority of poisonings in older people are unintentional and may result from dementia and confusion, improper use of the product, improper storage or mistaken identities. Depression is also common in the elderly and suicide attempts are more likely to be successful in this age group. The elderly patient's recuperative abilities may be inadequate as a result of numerous factors including impaired hepatic or renal function as well as chronic disease processes. General management of poisoning in the elderly parallels management of younger adults, but it is especially important to ascertain underlying medical conditions and concurrent medications. In most poisonings, activated charcoal and cathartic are sufficient. Haemodialysis or haemoperfusion may be required at lower plasma drug concentrations in elderly patients. While the specific indications for antidotes are the same for all age groups, dosage alterations and precautions may need to be considered in the elderly. Drugs most often implicated in poisonings in the elderly include psychotherapeutic drugs, cardiovascular drugs, analgesics and anti-inflammatory drugs, oral hypoglycaemics and theophylline. Cardiovascular and neurological toxicities occur with overdoses of neuroleptic drugs and, more frequently and severely, with cyclic antidepressants. Patients with pre-existing cardiovascular disease are at particular risk of worsening ischaemic heart disease and congestive heart failure. Benzodiazepines only appear to produce significant toxicity during long term administration or in combination with other CNS depressants. Digoxin can cause both chronic and acute intoxication, most seriously cardiac toxicity including severe ventricular arrhythmias, second or third degree heart block or severe refractory hyperkalaemia. Immune Fab antibody is indicated for the management of digoxin toxicity, although patients dependent on the inotropic effect of digoxin may develop heart failure after digoxin Fab antibody administration. Nitrates can cause toxicity including headache, vomiting, hypotension and tachycardia from excessive sublingual, transdermal or intravenous doses. Conduction disturbances and hypotension occur with overdoses of antihypertensive drugs; these effects are mild with angiotensin converting enzyme (ACE) inhibitors, occasionally severe with beta-blockers and of significant concern with calcium channel antagonists. The elderly commonly use aspirin and other salicylates, are more likely to develop chronic intoxications to these agents, and are more susceptible to severe complications such as pulmonary oedema. Salicylate poisoning, recognition of which is often delayed, should be considered in elderly patients with neurological abnormalities or breathing difficulties, especially in the setting of acid-base abnormalities. The clinical effects of NSAID overdose are mild and usually involve the central nervous system and gastrointestinal tract.(ABSTRACT TRUNCATED AT 400 WORDS)

A retrospective study on maternal mortality in pregnant women with cardiac disease over a period of eleven years (January 1979 to December 1989) was undertaken. The objective was an analysis of the main aspects of this association. Cardiac disease was diagnosed in 694 patients (4.2%) of a total of 16,423 admitted to the Obstetrics Department of the Escola Paulista de Medicina. As for etiology, rheumatic disease (52.3%); Chagas's disease (19.3%) and congenital disease (8.1%) were the most frequent causes. There were 51 maternal deaths, according to FIGO's definition (1967), corresponding to a maternal mortality rate of 428.2/100,000 livebirths during the same period. Twelve of these maternal deaths were due to cardiac disease (maternal mortality rate of 100.8/100,000 livebirths). The statistical analysis identified the following aspects associated with maternal mortality among patients with cardiac disease: primigravida, lack of adequate prenatal care, and cardiac surgery performed previously to and/or during pregnancy. Congestive heart failure with pulmonary edema (41.7%) and thromboembolism (25.0%) were the most frequent causes of maternal death among patients with cardiac disease. The NYHA functional classification was not a good parameter for pregnancy prognosis: eleven patients (91.7%) were considered as belonging to the favorable group before they became pregnant. Most maternal deaths occurred during the first 72 hours after delivery. Therefore, this period was considered most critical for maternal mortality in patients with cardiac disease. No relation-ship was found among the factors: maternal age, race, marital status, delivery and maternal mortality among patients with cardiac disease.(ABSTRACT TRUNCATED AT 250 WORDS)

We report cases of angina pectoris or minimal acute myocardial infarction accompanied by pulmonary edema, which were retrospectively studied with regard to their clinical characteristics, prognosis and treatment. Sixteen patients, 5 males and 11 females with a mean age of 72.6 years, admitted to the Cardiovascular Center of Sendai between January 1986 and June 1989, were studied. Ten had previous myocardial infarction. Hypertension, chronic renal failure and diabetes mellitus were found in 10, 7 and 7 patients, respectively. Electrocardiograms during cardiac ischemic attacks showed ST elevation in 8 and ST depression in the other 8 patients. Coronary arteriography which was performed in 6 patients revealed three-vessel disease in 5, and two-vessel disease in one. Mechanical ventilation was indicative of 7, and intraaortic balloon counterpulsation in 2 patients. Coronary artery bypass graft surgery was performed for 3 patients. All patients recovered from pulmonary edema and were discharged. During the mean 15-month-follow-up period, 8 patients died. The causes of death were sudden cardiac death in 3, acute myocardial infarction in one, congestive heart failure in one, post-surgical death in one, and non-cardiac death in 2.

During pilgrimage season (Hajj) in Saudi Arabia 34 patients with heat stroke (HS) were centrally cannulated to assess their state of hydration and fluid requirement during cooling period. Central venous pressure (C.V.P.) measurements indicated that most victims of heat stroke had normal C.V.P. on arrival at heat stroke centres and may not be fluid depleted. Twenty-two patients (64.7%) had normal or above normal C.V.P. Twelve patients (35.3%) had zero or below zero C.V.P. Six patients (17.6%) had above 10 cmH2O (range 10-26 cmH2O) and could have developed acute congestive heat failure and pulmonary edema if they had been transfused at the standard recommended rate of 3-4 litres of fluid during an average cooling time of 1 h as has been practiced in the heat stroke centres to date. This study also showed that heat stroke patients should not be briskly transfused because the heart may be affected by heat stroke per se and an unmonitored challenge by brisk i.v. therapy during cooling (which on its own increases preload on the heart due to peripheral vasoconstriction) can lead to acute overload problems. An average of 1 litre of normal saline or Ringer's lactate (crystalloids) was sufficient to normalize C.V.P. during the cooling period and to restore an optimal state of hydration without predisposing to congestive cardiac failure and pulmonary edema--the potential to develop disastrous adult respiratory distress syndrome and disseminated intravascular coagulopathy.
