Left ventricular performance was studied in 23 young patients with severe chronic anemia due to beta-thalassemia major and intermedia. The patients were divided into three groups according to the number of blood transfusions they had received. The left ventricle (LV) was enlarged in patients who had not received blood and larger still in patients who had received multiple transfusions. Echocardiography and systolic time interval measurements showed that systolic function of the LV was good in all the patients and that there was no statistical difference in systolic function in patients who had and those who had not received multiple transfusions. Heart rate was increased in the latter group. Stroke index and cardiac index were high, especially in patients in Group 3. The diastolic closure rate (EF slope) of the anterior mitral leaflet and its amplitude of movement were increased, but less so in Group 3; this may reflect an alteration in diastolic LV distensibility. The results indicate that despite the presence of cardiomegaly and severe clinical congestive heart failure, LV performance is well preserved in patients with beta-thalassemia, even in those who have received repeated blood transfusions. Clinical cardiac failure is the consequence of volume overload and abnormal chamber compliance. There was no evidence in this of a congestive cardiomyopathy.

Compensation for heart failure can be influenced by cardiac loads due to organ failure. This investigation studied the effect of secondary organ failure on the hemodynamics of acute heart failure. Of 106 patients with acute heart failure due to myocardial infarction or dilated cardiomyopathy, 49 (46%) patients had secondary organ failure, either kidney, liver, brain or blood. Their acute heart failure was sustained for significantly longer than that of 57 patients without organ failure. A transient but severe decompensation induced secondary organ failure, although the left ventricular ejection fraction was not different from that of the control without heart failure. Hypervolemia in cases of renal failure, bradycardia in loss of consciousness, hyperdynamic state in anemia and low blood pressure in liver dysfunction caused the sustained acute heart failure. These results suggested that secondary organ failure might occur in 46% of patients with acute heart failure, and might disrupt compensation by different kinds of hemodynamic loads in low cardiac function.

Among dialysis patients, only 23% have a normal echocardiogram, about 10% have recurrent or chronic congestive heart failure, and 17% have asymptomatic ischemic heart disease. The predisposing factors for congestive heart failure are dilated cardiomyopathy, hypertrophic hyperkinetic disease, and ischemic heart disease. Dilated cardiomyopathy, a disorder of systolic function, includes among its risk factors age, hyperparathyroidism, and smoking. Hypertrophic disease results in diastolic dysfunction, and its predictors include age, hypertension, aluminum accumulation, anemia, and, perhaps, hyperparathyroidism. Ischemic heart disease is due to the presence of coronary artery disease and also to nonatherosclerotic disease caused by the reduction in coronary vasodilator reserve and altered myocardial oxygen delivery and use. The clinical outcome of congestive heart failure is comparable to that of nonrenal patients with medically refractory heart failure. Left ventricular hypertrophy is an important independent determinant of survival. A subset have hyperkinetic disease with severe hypertrophy and have a bad survival, as low as 43% have a 2-yr survival after the first admission to hospital with cardiac failure. The prognosis for those with dilated cardiomyopathy is less severe but is worse than those with normal echocardiogram. The survival of patients with symptomatic ischemic heart disease was little different from that of patients without symptoms, suggesting that the underlying cardiomyopathies had an adverse impact on survival independent of ischemic disease. Much research needs to be undertaken on the risk factors, natural history, and therapy of the various types of cardiac disease prevalent in dialysis patients.

The paper is concerned with observations over 3 patients in whom unusual vasculitis lay at the basis of the clinicopathological manifestations. All the patients were men of the young age. The disease debut was marked by fever, weakness, dyspnea, palpitation, cough, hemoptysis, the articulation syndrome. In two cases, there was hemorrhagic rash on the leg skin. All the patients manifested liver and spleen enlargement, two patients had lymphoadenopathy. The leading clinical symptoms included dilated cardiomyopathy, complete blockade of the inferior peduncle of His bundle and reduction of myocardial contractility. Anemia belonged to iron deficient one. The clinical examples provided indicate that immunocomplex vasculitis with evident lesions of the lungs and myocardium, not going into criteria for the known diseases, is not likely to be a casuistic rarity. Those syndromes may be associated with more or less pronounced hemosiderosis of the lungs (and, probably, of the lymph nodes, spleen and liver), with transitory or steady derangements of myocardial conduction, which attests to diffuse lesions of the myocardium possibly with both immune complexes and hemosiderin. The pathology requires further studies.

Eight children with human immunodeficiency virus (HIV) infection had symptomatic cardiac dysfunction. The median age was 1.4 years (range 0.2 to 7.9 years). All had hepatosplenomegaly, fever, pneumonia with tachypnea, and tachycardia ascribed to infection and anemia. An S3 gallop was present in six of eight. All had normal creatine phosphokinase values. Chest x-rays did not aid in the diagnosis of cardiac dysfunction. ECG showed flattened T waves in five of eight with left ventricular hypertrophy, right ventricular hypertrophy, or both in seven of eight. Results of echocardiography showed decreased left ventricular function in all eight, despite anemia, with dilated left ventricular myopathy in six, concentric left ventricular wall thickening in two of eight, an enlarged right ventricle in two, and pericardial fluid in three. Medical therapy improved cardiac function in all. All patients subsequently died of noncardiac causes. Results of autopsies on four of eight patients showed focal myocarditis in two (with cytomegalovirus inclusions in one) and dilated cardiomyopathy in two others. We conclude: (1) Preexistent hepatosplenomegaly, fever, infection, and anemia result in physical findings that mimic findings of heart failure, thereby masking the occurrence of cardiac dysfunction; (2) an S3 gallop may indicate the presence of impaired heart function when other clinical signs are masked; (3) confirmation of cardiac compromise may be accomplished by noninvasive evaluation with echocardiography and (4) medical therapy can improve cardiac dysfunction in HIV-infected children.

Twenty-six patients with advanced, measurable epithelial carcinoma of the ovary were treated with 76 courses of esorubicin at doses ranging from 20-30 mg/m2 every 3 weeks. All patients are evaluable for toxicity and response. All patients had received prior therapy including radiation therapy in 9, non-anthracycline chemotherapy in 25, and surgery in 25. All patients were GOG performance status 0, 1 or 2. Two partial responses were seen. Severe (grade 3 or 4) leukopenia, thrombocytopenia, and anemia were seen in 13, 1 and 4 patients, respectively. Moderate gastrointestinal toxicity was also noted. Alopecia and mucositis were rare. Phlebitis was not seen. Neither clinical congestive cardiomyopathy nor decrement in left ventricular ejection fraction was observed. We conclude that using this dose and schedule of esorubicin as second-line chemotherapy in ovarian epithelial neoplasms lacks significant activity and is associated with moderate toxicity.

A cohort of patients with peripartum cardiac failure (PPCF) was followed for 10 years after the initial illness. The follow up rate was 78%. Fifty two per cent of patients improved without further episodes of heart failure. PPCF recurred in 26 per cent. Heart failure unrelated to pregnancy was seen in 13%, and 9% of the patients progressed to dilated cardiomyopathy. Transient hypertension was seen in 87% of patients on admission, and later hypertension was found in 45%. Late hypertension influenced heart size more when recurrent PPCF or progressive heart failure was present. Anaemia on admission had no effect on subsequent heart size. The electrocardiogram may continue to be abnormal for up to 10 years in normotensive patients who had no heart failure. The abnormal electrocardiogram in patients with persistent cardiomegaly may represent progressive myocardial damage. Mortality rate was highest (11%) in the first year and declined thereafter. Cardiac deaths were common in patients with recurrent PPCF or progressive heart failure.

A child with epidermolysis bullosa dystrophica, recessive type (EBDR) developed significant anemia at 9 years of age and was treated with long-term transfusion therapy. At age 17 he had symptoms of congestive heart failure secondary to dilated cardiomyopathy. Treatment with digoxin and vasodilators for the past year has failed to improve his cardiomyopathy significantly. Chronic iron overload and secondary hemosiderosis may have contributed to his problems, and we propose that chelation therapy be used in any child receiving long-term transfusion therapy.

Twenty-eight patients with advanced, measurable squamous carcinoma of the uterine cervix were treated with 62 courses of esorubicin at doses ranging from 20-35 mg/m2 every three weeks. All patients were evaluable for response and toxicity. All patients had received prior therapy including radiation therapy in 28, chemotherapy in 23, and surgery in 11. All patients were Gynecologic Oncology Group (GOG) performance status 0, 1 or 2. There were no responses seen. Severe (grade 3 or 4) leukopenia, thrombocytopenia, and anemia were seen in 13, 3, and 9 patients, respectively. Gastrointestinal toxicity as well as alopecia were the other adverse effects. Mucositis and phlebitis were not seen. Neither clinical congestive cardiomyopathy nor decrement in left ventricular ejection fraction was observed. Lack of response in association with moderate toxicity using this dose and schedule of esorubicin in squamous carcinoma of the cervix previously treated with chemotherapy makes further study as a salvage agent unwarranted.

Clinicopathologic features with special reference to the heart are presented in five fatal cases of acquired immunodeficiency syndrome (AIDS) in children. Three children showed clinical evidence of cardiovascular compromise or congestive heart failure. Autopsy was performed in all cases. The enlarged heart showed biventricular dilatation with grossly unremarkable valves and coronary arteries and absence of mural thrombi. Microscopic examination of the heart revealed primarily myopathic abnormalities with hypertrophy of the myocardium and only rare foci of sparse inflammatory infiltrate. The pathogenesis of dilated cardiomyopathy in these children with AIDS is not known. Infection, immunologic factors, anemia, deficiency of nutritional factor(s), and longer survival may be related to the pathogenesis. Pediatricians should be alert to the possibility of cardiac involvement in pediatric AIDS.
