The incidence of coronary artery disease only weakly correlates with the percent of excess body weight; however, obesity in humans is not a homogeneous condition. Classification of obesity based on anatomic distribution of body fat allows for identification of a group of patients at increased risk for cardiovascular disease. Abdominal (upper body) obesity, measured as the waist/hip ratio, is a strong independent risk factor of cardiovascular disease and should be used to assess a subgroup in need of medical weight loss treatment. A focus on dietary fat intake and the magnitude of overeating "caloric intake" are central to the pathogenesis of cardiovascular disease observed in the obese person. Identification of the process of overeating (magnitude of recent weight gain, episodes of weight cycling) is important in the design of successful medical nutrition treatment programs. A nutrition/medical history that includes age of obesity onset and duration of obesity provides additional criteria for assessment of risk of disease. Childhood-onset obesity and prolonged obesity (greater than 15 years) has been associated with increased cardiovascular disease risk. Recently, grades of obesity based on body mass index have provided a valuable marker for treatment. Each reduction in obesity grade (equal to delta 5 body mass index or delta 11.6 kg) is associated with a decrease in risk of medical illness. The new focus of obesity treatment should be to decrease body weight in 10% to 15% increments (equal to 1 grade) with emphasis on reducing the risk of medical illness and treatment intensity (e.g., number of existing medical visits, hospitalization).(ABSTRACT TRUNCATED AT 250 WORDS)

Five unusual cases of a right atrial mass in children are described to illustrate the very valuable contribution that two dimensional echocardiographic examinations can bring to both the initial diagnosis and the subsequent management of patients with these findings. One patient had a large benign hemangioendothelioma of the right atrium. Two infants had extension of a Wilms' tumor from the kidney by way of the inferior vena cava to the right atrium. A fourth patient, an 8 year old girl, had no cardiac disease, and manifested Staphylococcus aureus endocarditis of the tricuspid valve with a large pedunculated mass and subsequent pulmonary embolus. A fifth patient, a premature infant with a central hyperalimentation catheter in the right atrium, had a large thrombus on the catheter that was successfully eradicated with urokinase-induced thrombolysis. Two dimensional echocardiography provides real time imaging of the entire right atrium, interatrial septum, inferior and superior venae cavae and tricuspid orifice and hence is valuable in the diagnosis and management of these clinical problems.

A 39-year-old woman with long-standing anorexia nervosa was admitted to our hospital because of extreme weakness and cachexia. During a hyperalimentation therapy, she developed chest pain, revealing the electrocardiogram and cardiac enzymes a myocardial infarction of the inferior wall. We suggest that anorexia nervosa does not 'protect' against coronary atherosclerosis, and that some of the cases of sudden death could be related to myocardial ischemia.

We have studied the incidence of possible triggers of the myocardial infarction regarding its site in 750 patients with anterior and 731 patients with inferior infarction. Infarctions occurred most frequently without recalling any triggering activity, especially in patients with anterior infarction (67 vs. 44%). Physical effort as the possible precipitator was also more frequent in anterior infarctions (22 vs. 16%). However, the onset of inferior infarction was more frequent during meteorological stress (9 vs. 2%), emotional stress (10 vs. 3%), after overeating (13 vs. 3%) and nicotine abuse (6 vs. 1.5%). These triggers were independent and highly significant (P < 0.02 in each case) discriminators of the site of myocardial infarction. Bimodal circadian rhythm, with primary peak between 6 and 9 h a.m. and the secondary peak between 3 and 6 p.m. was observed in patients which did not recall any triggering activity, and this was more pronounced in patients with inferior infarction. These results support the hypothesis that the influence of the vegetative tone is most pronounced in the onset of myocardial infarction of inferior wall.

Coronary heart disease remains a major cause of morbidity and mortality in the United States, and its incidence is rising worldwide. Because atherosclerosis is a chronic process, and it is often associated with certain lifestyle and risk factors such as hypertension, dyslipidemia, and insulin resistance, much emphasis is being placed on lifestyle modification and control of risk factors. It is being recognized that some lifestyle patterns such as overeating result in metabolic syndrome, which may play a role in the development of chronic kidney disease and coronary heart disease. Here, we focus on an important relationship between these 3 conditions, and we provide evidence that microalbuminuria develops in many patients with metabolic syndrome, may be an important correlate of chronic kidney disease and coronary heart disease, and may represent an important prognostic marker. Although the pathogenesis of microalbuminuria in metabolic syndrome is not clear, we suggest that microalbuminuria, chronic kidney disease, and coronary heart disease share common pathways involving inflammation and oxidative stress. We also discuss that a healthy lifestyle is essential for preventing and treating chronic kidney disease and coronary heart disease seen in patients with metabolic syndrome.

Normalization of hyperglycemia, hyperlipidemia and oxidative stress is an important objective in preventing diabetes-induced cardiac dysfunction. The present study investigated the effects of the fruit juice obtained from Emblica officinalis on myocardial dysfunction in diabetic rats. Diabetes was induced by streptozotocin (STZ), and the rats were treated with E officinalis fruit juice for eight weeks. Injection of STZ produced loss of body weight, polydypsia, polyphagia, hyperglycemia, hypoinsulinemia and dyslipidemia. It also produced hypertension, bradycardia, hypertrophy and myocardial functional alterations associated with an increase in serum lactate dehydrogenase and creatinine kinase-MB levels. Treatment with the fruit juice not only prevented STZ-induced loss of body weight, increases in water and food intake, increases in serum glucose levels and disturbed lipid profile, but also an increase in serum lactate dehydrogenase and creatinine kinase-MB levels, and increased myocardial hypertrophy and cardiomyopathy. There was an increase in the area under the curve (AUC) for glucose, and a decrease in AUC(insulin) was observed in diabetic rats; treatment decreased AUC(glucose) but not AUC(insulin) or hyperinsulinemia. There was a decrease in antioxidant enzyme levels (in superoxide dismutase, reduced glutathione and catalase) in diabetic hearts, which could be improved by treatment with fruit juice. The present data suggest that fruit juice may be beneficial for the treatment of myocardial damage associated with type 1 diabetes mellitus. The activity of E officinalis fruit juice can be attributed to the concentration of polyphenol present.
