Severe cardiac arrhythmias (Lown class IVa), rapid loss of physical capacity and dyspnoea on the slightest exertion occurred in a 55-year-old man with idiopathic dilated cardiomyopathy. In the preceding year he had recurrent diarrhoea and lost 23 kg in weight. He was found to have hypercalcaemia (3-3.2 mmol/l). The heart failure significantly improved under treatment with twice daily 12.5 mg captopril, 100 mg spironolactone daily, furosemide 40 mg twice daily, and digitoxin 0.07 mg daily. The arrhythmia responded to verapamil 80 mg and quinidine 160 mg, both drugs three times daily. Primary hyperparathyroidism was found to be the cause of the hypercalcaemia (parathormone 84 pmol/l). After the parathyroid adenoma had been removed the patient's condition again improved markedly. There were only rare monotopic extrasystoles, cardiac size regressed, and diuretics were no longer necessary. His medication at present is verapamil (80 mg three times daily), captopril (12.5 mg three times daily) and digitoxin (0.07 mg daily). It is concluded that the hypercalcaemia influenced the severity of the cardiomyopathy. It would seem that both intra- and extracellular calcium homoeostasis is of great importance in dilated cardiomyopathy.

Acromegaly was diagnosed in 14 middle-aged to old cats of mixed breeding. Thirteen (93%) of the cats were male and one was female. The earliest clinical signs in the 14 cats included polyuria, polydipsia, polyphagia, all of which were associated with untreated diabetes mellitus. All developed severe insulin resistance within a few months; peak insulin dosages required to control severe hyperglycemia ranged from 20 to 130 U per day. Other clinical findings weeks to months after diagnosis included enlargement of one or more organs (e.g., liver, heart, kidneys, and tongue) (n = 14), cardiomyopathy (n = 13), increase in body size and weight gain (n = 8), nephropathy associated with azotemia and clinical signs of renal failure (n = 7), degenerative arthropathy (n = 6), and central nervous system signs (i.e., circling and seizures) caused by enlargement of the pituitary tumor (n = 2). The diagnosis of acromegaly was confirmed by demonstration of extremely high basal serum growth hormone concentrations (22 to 131 micrograms/l) in all cats. Computerized tomography disclosed a mass in the region of the pituitary gland and hypothalamus in five of the six cats in which it was performed. Two cats were treated by cobalt radiotherapy followed by administration of a somatostatin analogue (octreotide), whereas two cats were treated with octreotide alone. Treatment had little to no effect in decreasing serum GH concentrations in any of the cats. Eleven of the 14 cats were euthanized or died four to 42 months (median survival time, 20.5 months) after the onset of acromegaly because of renal failure (n = 2), congestive heart failure (n = 1), concomitant renal failure and congestive heart failure (n = 3), progressive neurologic signs (n = 2), persistent anorexia and lethargy of unknown cause (n = 1), the owner's unwillingness to treat the diabetes mellitus (n = 1), or unknown causes (n = 1). Results of necropsy examination in ten cats revealed a large pituitary acidophil adenoma (n = 10), marked left ventricular and septal hypertrophy (n = 7), dilated cardiomyopathy (n = 1), arthropathy affecting the shoulder, elbow, or stifle (n = 5), and glomerulopathy characterized by expansion of the mesangial matrix and variable periglomerular fibrosis (n = 10).

Tuberous sclerosis is a neurologic disease affecting various organs with a triade: sebaceum adenoma, mental retardation and seizures. This report presents a case of a patient with tuberous sclerosis and third degree A-V block with complete invasive and non-invasive evaluation. The patient had sincope and complete A-V block with QRS complexes showing right bundle branch block morphology. The echocardiogram showed dilated cardiomyopathy with diffuse left ventricular dysfunction and had normal coronary arteriography. The eletrophysiologic evaluation showed complete infra-hisian A-V block and QRS with left bundle branch block pattern with normal sinus nodal and A-V nodal function. It was not possible to induce ventricular tachtyarrhythmias up to two extrastimuli. Histologic study showed normal myocardium under light and electronic microscopy. After permanent VVI pacemaker implant, the patient in follow-up for 16 years. This case seems to be the first in the international medical literature of tuberous sclerosis with complete heart block.

Cushing's Syndrome (CS) may sometimes lead to dilated cardiomyopathy, even though this condition can be partially or completely reversed after treatment. In this article we report the case of a 28-yr-old woman with CS secondary to adrenal adenoma who exhibited congestive heart failure as an initial symptom. Two weeks before being admitted to our hospital, the patient started complaining of shortness of breath, orthopnea, paroxysmal nocturnal dyspnea and generalized edema. A physical examination did not reveal signs of hypercortisolism. Chest auscultation revealed bilateral diffused crepitation; blood pressure was 180/120 mmHg with heart rate of 90 beats/min. A chest X-ray showed a cardiac shade enlargement due to congestive heart failure. Transthoracic echocardiography demonstrated a dilated left ventricle and an impaired left ventricular systolic function. The patient's urinary cortisol excretion was elevated and circadian rhythm of cortisol was absent. ACTH level was low. In addition, plasma cortisol failed to decrease after administration of dexamethasone. An abdominal magnetic resonance imaging scan showed a 7-cm right adrenal mass. The patient was administered oxygen, spironolactone, ACE-inhibitor and the signs and symptoms of heart failure gradually improved. A laparoscopic right adrenalectomy was performed and pathological examination of the gland showed a benign adrenocortical adenoma. After the adrenalectomy the patient was started on hydrocortisone therapy and 5 months later the wall thickness of the left ventricle was within normal range and the patient's blood pressure was 130/80 mmHg. In conclusion we report the case of heart failure as the main clinical symptom in CS secondary to adrenal adenoma.

In this overview of success stories in veterinary clinical nutrition topics in cats and dogs reviewed include the dietary management of chronic kidney disease, dissolution of urinary tract uroliths by dietary modification, the recognition that taurine and L-carnitine deficiencies can cause dilated cardiomyopathy; that clinical signs associated with feline hyperthyroidism (caused by a benign adenoma) can be controlled by a low-iodine diet alone; that dietary management of canine osteoarthritis can also reduce non-steroidal anti-inflammatory drug doses; and that disease-free intervals and survival times can be statistically longer in dogs with Stage III lymphoma managed with diet. As we discover more about nutrigenetics and nutrigenomics, and as we expand our basic understanding of idiopathic diseases we are bound to identify more nutritionally related causes, and be able to develop novel dietary strategies to manage disease processes, including the formulation of diets designed to alter gene expression to obtain beneficial clinical outcomes.
