Objective-To determine whether there is an association between hepatitis C virus (HCV) infection and dilated cardiomyopathy in a well defined area of north western Greece; such an association has been reported elsewhere. Design-Evaluation of consecutive patients with chronic HCV infection for the presence of clinical or subclinical manifestations of dilated cardiomyopathy by history, physical examination, and noninvasive laboratory procedures (ECG, chest x ray, and echocardiography) before the initiation of interferon treatment; investigation for HCV infection markers in patients with dilated cardiomyopathy by enzyme and immunoblot assays (antibodies to HCV) and the reverse transcriptase polymerase chain reaction (HCV RNA). Setting-A tertiary referral centre for patients with chronic hepatitis and dilated cardiomyopathy. Patients-102 patients with well defined chronic HCV infection and 55 patients with well established dilated cardiomyopathy were evaluated. Main outcome measures-The need for HCV testing in patients with dilated cardiomyopathy, or follow up for heart disease in patients with chronic HCV infection. Results-None of the patients with chronic HCV infection had clinical or subclinical evidence of dilated cardiomyopathy from history and laboratory findings. None of the patients with dilated cardiomyopathy was positive for antibodies to HCV or viraemic on HCV RNA testing. Conclusions-The study neither confirms the findings of other investigators, nor indicates a pathogenic link between HCV and dilated cardiomyopathy. For this reason, at least in Greece, testing for HCV in patients with dilated cardiomyopathy or follow up for heart disease in HCV patients appears unnecessary. Genetic or other factors could be the reason for this discrepancy if previously reported associations between HCV and dilated cardiomyopathy or hypertrophic cardiomyopathy were not coincidental.

The aim of this study is to investigate systemic sclerosis (SSc) patients without clinically evident heart disease for cardiac abnormalities. SSc patients and age- and sex-matched healthy controls from the hospital staff underwent transthoracic echocardiography for the assessment of the left ventricle (LV) morphology and function and estimation of the pulmonary artery systolic pressure (PASP). Patients further underwent stress-rest myocardial perfusion imaging (MPI) scintigraphy by single-photon emission computed tomography (SPECT). Thirty-seven patients were included (33 women, 19 with diffuse, and 18 with limited SSc). LV hypertrophy was more common in SSc patients than controls (24.3 vs 0 %, p = 0.001). Impaired LV relaxation was found in 45.9 % of patients and 40.5 % controls (p = 0.639). Excluding patients with arterial hypertension, LV hypertrophy was still found in 23.1 % and LV relaxation impairment in 38.5 %. PASP over 30 mmHg was found in 13 patients (35.1 %), 11 of whom had no history of pulmonary arterial hypertension (PAH). Of 35 patients who underwent SPECT, 21 patients (60 %) exhibited reversible LV perfusion defects. Their mean age was 51.8 years; four patients were younger than 40 years old and eight patients younger than 50 years. In all cases, ischemia was graded as mild or moderate and in a single case, graded as significant. Subclinical heart involvement is common in SSc patients even in the younger age groups. LV hypertrophy and impaired relaxation, raised PASP, and ischemia on MPI with SPECT are found in a significant proportion of SSc patients. Careful screening of SSc patients for potential heart involvement and consultation by a cardiologist may be of value.
In a retrospective study on 59 patients (2 hypothalamic, 44 pituitary, 13 no confirmed disease) 69 pairs of insulin hypoglycemia tests (IHT) and short metyrapone tests (SMT) were evaluated. Cortisol and 11-desoxy-cortisol rsp. were compared as the endpoints. In 6 cases, the IHT was a technical failure because of insufficient hypoglycemia. In 25% of 63 pairs of tests, both tests were normal, (Group I), in 30% both abnormal (Gr. II). In 21%, IHT was normal, SMT abnormal (Gr. III) and in 24% IHT was abnormal and SMT normal (Gr. IV). The 2 patients with hypothalamic disease were in Group IV with completely normal SMT and severely pathological IHT. Other discrepancies could not be attributed to special pituitary disorders. In 9 patients of Group III and in 8 patients of Group IV (n = 17), the IHT alone was repeated 6-48 months after the original pair of tests which had been performed in most cases early after pituitary surgery. In 12 cases, the repeat IHT followed the trend of the SMT of the original test pair. In 5 cases, the IHT was unchanged. 14 of 19 patients of Group II, but only 5 of 28 patients of Group III and IV required permanent substitution with hydrocortisone.
A case of double left anterior descending coronary artery in a patient with isolated corrected transposition of great arteries is presented. The double artery originated from the left main stem and the right coronary artery. There were no stenoses on these two arteries. This anomaly seems to be very rare.
