A 63 year old female, who was admitted to a psychiatric hospital for schizophrenia, was referred to our emergency room because of sudden loss of consciousness and convulsions. On arrival, she was drowsy and hypoxemic. Her chest X-ray showed cardiomegaly with pulmonary edema. ECG showed marked ST depression in precordial leads and serum chemistry revealed marked elevation of CPK, GOT and LDH along with hyponatremia and hypochloremia. She was immediately admitted to CCU on suspicion of acute non-transmural myocardial infarction complicated with congestive heart failure. After fluid restriction and intravenous infusion of dopamine she passed large amount of urine, and her consciousness level, electrolyte imbalance and ECG change, improved gradually. Although serum CPK level increased as high as 32,307 IU/ml, there were no signs of left ventricular asynergy on UCG and CPK isozyme analysis performed later revealed more than 99% of serum cCPK was MM-type. We concluded that water intoxication was the cause of the ECG change and the elevated serum CPK, GOT and LDH levels. There are few reports on elevated CPK level in association with water intoxication, in which rhabdomyolysis is speculated as the cause of CPK elevation. But there is no report on ECG change complicated with water intoxication. In our case, electrolyte imbalance caused by water intoxication seemed to play a major role in ST depression and QT prolongation. Although water intoxication is a rare disorder in the general population, it is not infrequent among patients with psychiatric diseases. Care must be taken when such patients present ECG change and serum enzyme elevation mimicking ischemic heart disease.

The objective of this study was to determine the probabilities of specific morbid events or death among patients with end-stage renal disease (ESRD) treated by hemodialysis. A prospective cohort study was performed between March 1988 and September 1989 in 18 hemodialysis centers in 13 Canadian cities, representing about one third of the hemodialysis population in Canada. The inception cohort consisted of 496 patients entering hemodialysis who had survived 1 month. The few new hemodialysis patients who received erythropoietin (EPO) in the last 3 months of the study were excluded. Survival curves were compared using the Cox proportional hazards regression model. Older age and history of cardiovascular disease were independently associated with a greater probability of death. Age and history of cardiovascular disease were also associated with a greater probability of nonfatal circulatory events (myocardial infarction, angina requiring hospitalization, or stroke), while a serum albumin level less than or equal to 30 g/L (3.0 g dL) was associated with an increased probability of pulmonary edema. The probability of surviving 12 months without receiving a blood transfusion was 47.2% for males and 27.5% for females. The incidence of non-A, non-B hepatitis, as estimated by unexplained elevations in serum aspartate aminotransferase (AST) values, was not different between patients receiving and not receiving blood transfusions. The probability of hospitalization for any cause was greater for patients with grafts for vascular access than for those with fistulae, for those with a history of cardiovascular disease, for those with a serum albumin level less than or equal to 30 g/L, and for those with renal disease due to diabetes or vascular disease. Hospitalization due to circulatory disease was more likely among those with a history of cardiovascular disease and among those with a lower serum albumin level. Hospitalization for infectious disease was more likely among those with a lower serum albumin level and less likely among those with a fistula for vascular access. Among all patients receiving hemodialysis treatment for more than 6 months, there were 14.8 hospital days per year.(ABSTRACT TRUNCATED AT 400 WORDS)

A 32-year-old man (weight 132 kg, height 190 cm) suddenly became unconscious and cyanosed with an unrecordable pulse and ventricular flutter on ECG. After resuscitation, the blood pressure was 200/100 mm Hg; the patient moved his arms and legs at times, but he did not regain consciousness. Focal neurological signs and meningism were not demonstrable. Subsequent ECGs showed a raised ST segment, followed later by terminal T wave inversion; marked pulmonary oedema was present clinically and radiologically. The creatine kinase activity was 344 U/l. As lateral myocardial infarction was suspected, the patient received heparin (1000-1700 IU/h) and nitroglycerin intravenously. Because the CK-MB isoenzyme failed to rise significantly and there was no reduction of R wave on the ECG, a CT scan of the brain was performed: this showed brain oedema as well as severe subarachnoid haemorrhage in the basal subarachnoid space, the posterior horn of the lateral ventricles and over the cerebral hemispheres. Despite implantation of an epidural pressure gauge, hyperventilation and administration of dexamethasone, osmotic diuretics and thiopental, the patient died 14 days after collapsing. At autopsy the heart showed no signs of myocardial infarction. The cause of the subarachnoid haemorrhage was a ruptured aneurysm of the anterior communicating artery.

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.

Scorpion envenomation is a common medical problem and life hazard in many countries of the world. Scientific investigations have addressed the interrelationship between the stimulatory effects of the venom on the autonomic nervous system and adrenals and the subsequent effects of released transmitters on the cardiovascular system. A number of clinical cardiovascular syndromes may dominate the initial clinical presentation after envenomation: the syndromes usually vary with the age of the victim, the size of the offender and the season. Central nervous system dysfunction is seen in children but rarely observed in adults; if accompanied by severe hypertension the clinical picture is consistent with acute hypertensive encephalopathy. Heart failure, pulmonary edema or a shock-like syndrome has been observed in 25% and hypertension in 30% to 77% of our patients. The electrocardiographic abnormalities recorded in the majority of the patients after envenomation include an "acute myocardial infarction-like pattern." Rhythm disturbances are frequent but conduction abnormalities are rare. Echocardiographic, radionuclide and experimental hemodynamic observations have provided evidence that heart failure and pulmonary edema after envenomation are multifactorial with diminished systolic performance following the initially increased left ventricular contractility and decreased ventricular diastolic compliance. Clinical laboratory data reporting increased catecholamine metabolite excretion and elevated plasma renin and aldosterone are consistent with the stimulatory effects of the venom on the autonomic nervous system. Treatment, including our experience with vasodilators and calcium channel blockers, is reviewed.

Experiments in 150 albino rats have revealed that hyperbaric oxygenation (303.98 kPa) causes no decrease in pulmonary tissue hyperhydration and its blood filling induced by pituitrin administration. Hyperbaric oxygen therapy enhances pulmonary tissue peroxidation of lipids, without modifying them in blood. Application of lipid peroxidation inhibitors to prevention of pulmonary edema fails to affect pulmonary hydration and blood filling, which does not rule out the possibility of using them as protective agents against the toxic effects of oxygen in myocardial infarction which may be complicated by acute pulmonary edema.

We retrospectively reviewed 443 patients who had cardiopulmonary resuscitation (CPR). The focus of the study was to discover what preexisting factors should be assessed to determine the probability of survival. There were 88 successes out of 340 cases (25.9%). The absence of a previous myocardial infarction (MI), shock, partial pressure of oxygen (PaO2) less than 60 mm Hg, blood urea nitrogen (BUN) level greater than 20 mg/dL, pneumonia, pulmonary edema, and oliguria were found to predict a successful outcome. Logistic regression was used to predict percentage of successes in the various groups of patients with various clinical characteristics. The observed and predicted numbers of successes were in close agreement in most cases. We also constructed a classification function to predict whether an individual subject would survive the event for which CPR was required. Sixty-seven of the 88 observed successes would have been predicted, for an estimated sensitivity of 76%, and 164 of the 252 failures would have been predicted, for an estimated specificity of 65%. A large percentage (24%) of cases in which the patient actually survived CPR would have been predicted to be failures. We conclude that preexisting factors before a cardiopulmonary arrest do not accurately predict survival after CPR.

A 76-year-old woman with an inferior wall myocardial infarction, with right ventricular involvement, developed severe arterial hypoxemia with neurological involvement. Pulmonary edema or embolism and chronic obstructive pulmonary disease were ruled-out, and a right-to-left shunt was demonstrated by contrast echocardiography at the level of the foramen ovale. After inotropic support and oxygen supplementation, the patient recovered, although with significant neurological sequelae. No focal lesions were detected in the central nervous system by computerized tomography. Hypoxemia improved, coinciding with the disappearance of right-to-left shunt by contrast echocardiography.

A total of 3000 patients have had cardiac catheterization in the Andreas Gruentzig Cardiovascular Laboratory of the Emory Clinic. The purpose of this presentation is to describe the patient population selected for this procedure and our experience with this group. The concept of catheterization as an outpatient is attractive from the standpoint of cost savings and time conservation. Safety has been questioned. We have found that this technique can be performed safely in carefully selected outpatients. Careful selection attempted to eliminate those with unstable symptoms, recent myocardial infarction, severe diabetes, and renal failure. Small catheters were used to minimize the potential for bleeding. Excellent opacification of vessels was obtained with these catheters. Despite careful screening we found 2.2% had significant left main obstruction, 10.8% had triple-vessel disease, 16.0% had double-vessel disease, and 23.5% had single-vessel disease, and a similar percentage had normal coronary arteriograms. Our patients experienced ventricular fibrillation on five occasions, there were two small cerebral emboli with reversible neurologic defects, two episodes of pulmonary edema, and two episodes of severe allergic reactions. Only three patients had significant groin bleeding at home that required compression of the site. We subsequently did angioplasty on 323 patients, performed cardiac surgery (mostly coronary bypass) on 187 patients, and admitted 18.2% of the entire group. We conclude that this procedure can be done safely in this carefully designed setting and it saves time and offers cost savings. Patient selection is very important to minimize potential emergency situations and complications. The laboratory must be carefully set up and provide a close relationship with a hospital capable of attending to any unexpected emergency.

E-D is a powerful technique that can provide invaluable information in the acutely ill cardiac patient. It can help in the early diagnosis of conditions causing acute chest pain such as AMI and aortic dissection. E-D can help diagnose the causes of underlying hemodynamic instability such as hypotension and pulmonary edema, and it can help determine the initial management strategy. In this regard, E-D can replace Swan-Ganz catheterization in most patients. In patients with AMI who may appear to be hemodynamically stable, it can provide information regarding the following: size of risk area; status of the regions of the myocardium remote from the infarcted zone; effect of reperfusion therapy on regional myocardial function; presence or absence of nonsurgical complications such as ischemic mitral regurgitation, LV thrombus, or aneurysm; and patients at risk for immediate or late cardiac events. It is likely that as the newer generation of cardiologists becomes adequately trained in E-D, this technique will find routine use in every critical care unit.
