Patients in the coronary care unit with acute pulmonary edema, heart failure, and other organic heart disease were studied. Blood and urine samples were taken on admission prior to any treatment and later at prescribed intervals. All the patients with APE were found to have elevated plasma osmolalities and hyperglycemia on admission which decreased with treatment. This was in contrast to the other two groups excluding those factors such as ethyl alcohol and diabetes which can raise plasma osmolality or blood glucose. A discussion of this mild hyperosmolal state in APE follows including possible causes as well as cellular effects of hyperosmolality on humans.

The plasma level of the immunoreactive insulin and the blood level of sugar on an empty stomach and following carbohydrate provocation were determined in 31 patients with congestiva heart failure due to ischaemic heart disease. In 26 of them the plasma levels of adrenalin and noradrenalin were also studied. After 30-35 days of active therapy 15 patients were reexamined. The immunoreactive insulin plasma level was determined by the Hales and Randle technique, that of catecholamines-flowmetrically by the trioxyindol method after Vendsalu modified by E. Sh. Matlina. Carbohydrate metabolism disorders that manifested themselve in fasting hyperglycemia and in changing tolerance of glucose were noted in 13 of the 31 patients, examined. In the majority of patients with congestive heart failure insulin secretion was reduced both after fasting and after glucose administration. The improvement of the patients state in response to the employed therapy was accompanied by an increasing insulin secretion. One of the causes of the inhibition of insulin secretion in patients with congestive heart failure consisted in hypercatecholaminemia that was noted in most of the examined cases. The obtained data prove the necessity of a careful control of carbohydrate metabolism in patients with congestive heart failure and of a more active employment of insulin for their treatment.

The experience is reviewed on the use of superhigh insulin doses 1200 to 3800 U (31.4 +/- 5.3 U/kg) for the treatment of acute heart failure in 17 patients subjected to open heart surgery. Symptoms of heart failure refractory to catecholamines and vasodilators were accompanied by marked hyperglycemia (23.1 +/- 4.3 mmol/l). It was impossible to discontinue assisted circulation. In 82.3% of patients myocardial contractility upon insulin administration improved considerably, which led to discontinuation of assisted circulation with moderate inotropic support. Possible mechanisms ensuring the efficacy of massive insulin therapy in patients with acute heart failure are discussed.

Ischemic hepatitis is not an uncommon complication of reversible severe hypotension or cardiac failure. The prognosis usually is determined by the cause of the initial hypotension or cardiac failure, rather than the subsequent hepatic dysfunction. We report a retrospective analysis of nine patients with ischemic hepatitis in which previously unreported clinical and biochemical abnormalities are noted. The clinical and biochemical course of the patients were reviewed until recovery or death from ischemic hepatitis. All the patients had a rapid striking elevation of aspartate aminotransferase, and lactic dehydrogenase, with an equally rapid resolution of these parameters. Abnormal serum glucose levels occurred in six patients (none of whom had a prior carbohydrate intolerance). Insulin therapy was given to three patients for a limited period. Renal impairment was manifest in all nine patients, and it resolved spontaneously within 10 days. Altered mental status was detected in six patients; the changes reverted to normal within 7 days of their onset. A preexisting anemia (hemoglobin less than 11.0 g/dl) was noted on admission in four patients, and it did not appear to potentiate the manifestations of the hepatic ischemia. We conclude that ischemic hepatitis should be anticipated in all patients with a recent history of systemic hypotension. It should be considered in the differential diagnosis of patients with unexplained hepatitis; the early massive rise in lactic dehydrogenase, the rapid fall in transaminases, and the early mild/moderate renal failure strongly suggest ischemic hepatitis. Patients with ischemic hepatitis can manifest reversible renal failure, mental confusion, and hyperglycemia which may require insulin for its control.

Late complications of diabetes mellitus include a variety of clinical pictures, mainly related to the involvement of the arterial wall both of large vessels (macroangiopathy) and small vessels (microangiopathy), and of the peripheral nervous system (neuropathy). Their presence in almost all types of diabetes indicates that there is a common pathogenetic mechanism, which can be substantially identified in high blood glucose levels and related alterations. Hyperglycemia, in fact, leads to some metabolic abnormalities, i.e. non-enzymatic glycosylation of proteins and polyol pathway activity; moreover it can negatively affect the pattern of some hormones, especially GH and sex steroids, and normal rheological and clotting properties of blood. These abnormalities, confirmed by experimental models, play a key role in the development of late diabetic complications. However some evidence indicates that a genetic background may predispose to their development or protect from their onset. The two main forms of diabetic retinopathy, non-proliferative and proliferative, show an incidence which increases with age and duration of diabetes, reaching 100% when diabetes lasts for more than 20 years. The risk of blindness, which is very high for the proliferative form, has been dramatically reduced by laser-photocoagulation. Diabetic nephropathy affects a lesser number of diabetics but, after a silent or preclinical stage, leads to renal failure and subsequent replacement therapy. Strict metabolic control in the silent stage and later rigid anti-hypertensive treatment can prevent or retard the evolution of this complication. A close association has been observed between diabetes and hypertension, which can directly affect the onset and evolution of diabetic nephropathy, probably through a common genetic mechanism. Diabetic neuropathy has a wide variety of clinical manifestations, at somatic, autonomic and central levels and can greatly modify the quality and expectancy of life. However, the major cause of death in diabetic subjects is large vessel disease or macroangiopathy, which is similar to non-diabetic atherosclerosis regarding the main histopathological and clinical manifestations but has a much higher prevalence and severity. Finally, a specific cardiomyopathy has also been described in diabetes mellitus and can account for the high rate of heart failure observed in these patients.

Many pharmacologic agents are effective in normalizing blood pressure in the hypertensive patient. The major issues in antihypertensive therapy today transcend control of blood pressure and focus, instead, on safety considerations, patient acceptance, and additional benefits to target organs. With the drugs currently available, 10-15% of patients withdraw from therapy because of undesirable clinical side effects. Nonclinical side effects such as hyperlipidemia, hypokalemia, and hyperglycemia can limit the clinician's choice of drugs, especially for elderly patients. Antihypertensive agents should also limit target organ damage. The prevalence of stroke can be reduced solely by controlling blood pressure, but inhibition of cardiac ischemic events requires use of specific classes of agents. Beta blockers reduce mortality and reinfarction postmyocardial infarction, whereas angiotensin-converting enzyme (ACE) inhibitors affect several factors leading to heart failure, including cardiac and vascular hypertrophy, remodeling and dilatation postmyocardial infarction, and arrhythmias. Specific actions on intrarenal and other vascular dynamics may make these drugs appropriate for use in patients with diabetes and perhaps hypertensive kidney disease and systemic arterial disease. The range of options available in antihypertensive therapy in the 1990s affords the physician the opportunity to meet additional goals of therapy, specific for each patient.

The purpose of this article was to review the clinical and experimental features of diabetic cardiomyopathy, with particular relevance to the Black population. One hundred thirty-seven studies were identified, of which 57 were selected as references for this article. Diabetes is associated with the development of cardiomyopathy, independent of coronary atherosclerosis. Pathological studies show myocardial hypertrophy and fibrosis; microvascular pathology is also present, but all of these pathological findings have an uncertain relationship to myocardial failure. Hemodynamic findings of both congestive and restrictive cardiomyopathy have been described. Noninvasive studies revealed abnormal systolic and diastolic function in many diabetic subjects, particularly in the presence of diabetic complications and/or hypertension. Experimental studies have focused on the mildly diabetic dog and the severely diabetic rat. One year of diabetes in dogs resulted in decreased left ventricular compliance and increased interstitial connective tissue. Studies in the diabetic rat showed a marked slowing of contraction and relaxation. Chronic insulin therapy reversed the changes in the rat model. Combining hypertension with diabetes in the rat resulted in increased myocardial and coronary microvascular pathology and greater changes in isolated muscle function, electrophysiology, and contractile protein biochemistry. Many hypertensive diabetic rats died spontaneously, showing signs of congestive heart failure. Diabetic cardiomyopathy is a significant cause of heart failure in diabetic subjects and occurs more frequently in those with microvascular complications and/or hypertension. Clinical studies are needed to clarify the natural history of this disorder, focusing on the benefits of tight control of hyperglycemia and treatment of associated hypertension. Experimental studies will clarify the pathophysiology and contribute to improved therapy. The high prevalence of diabetes and hypertension in Blacks makes these considerations especially relevant to this population.

To elucidate the nature of lipid defects in patients with diabetes mellitus (DM) concurrent with acute myocardial infarction (MI), the study was undertaken to examine the serum concentrations of total cholesterol, triglycerides, alpha- and beta-lipoproteins with DM in the presence of acute MI. 40 non-diabetic patients with acute MI, 23 diabetics with postinfarct cardiosclerosis, and 17 non-insulin-dependent diabetics without signs of coronary atherosclerosis. Urinary epinephrine and norepinephrine excretion was additionally determined in the acute period and 3-4 weeks after therapy. Homogeneous lipid metabolic parameters were found in CHD patients with and without DM and when transient hyperglycemia developed. The patients with acute MI exhibited some increase in lipid consumption to satisfy the energy need for the cardiovascular system, this being true for triglycerides in DM patients. The DM patients who showed low triglyceride levels had more frequently transmural MI and MI complicated with heart failure. Obesity and familial histories of DM and CHD in DM patients with acute MI were ascertained to be accompanied by reduced serum alpha-lipoprotein concentrations.

The authors describe a term female, asphyxiated, small for gestational age (SGA) infant with documented hyperinsulinism and hypoglycemia occurring at approximately 45 hours of age. The hypoglycemia was refractory to a high rate glucose infusion and steroid administration but responded to diazoxide. The subsequent hospital course was complicated by right-sided heart failure and sepsis. With the onset of sepsis, a transient hyperglycemia was noted that required intermittent insulin therapy for 10 days. Hypoglycemia and hyperinsulinism reemerged and responded to diazoxide therapy. An attempt to discontinue diazoxide at age 6 months was aborted at 2 weeks when hyperinsulinism and hypoglycemia recurred. The infant required diazoxide for 7 more months, then she recovered without having any sequelae. The review of this uncommon hypoglycemia etiology in an SGA and asphyxiated infant and the merits of long-term diazoxide treatment are discussed.

Of 1894 patients registered in a family medicine clinic, 101 (5.3%) had been taking diuretics for at least 6 months. The sex distribution was equal and the average age was 68.7 years. 60% were taking Kaluril, 30% Aquadon and 10% Frusemide. Most had hypertension or heart failure, or both. 6 patients developed hyperglycemia, 2 hyponatremia, 5 hypokalemia, 2 hyperkalemia and 10 hyperuricemia. In 19 the ECG showed arrhythmias. 5 of 56 patients had hypomagnesemia and another 12 had low borderline levels. In the light of these results and those in the literature, we conclude that diuretics are not as safe as previously thought.
