[Relationship between the slow coronary flow and carotid artery intima-media thickness]. / Koroner yavas akim ile karotis intima-media kalinligi arasindaki iliski.

OBJECTIVE: This study was planned to investigate the relationship between slow coronary flow and the carotid artery intima-media thickness (CIMT) which is an indicator of early atherosclerotic changes in vascular tree. METHODS: Consecutive patients (n=203) who were free of any coronary lesions in coronary angiograms were enrolled. The patients were assigned into slow flow (97) and normal flow (106) groups according to the corrected TIMI frame count (CTFC) of every three coronary arteries. Carotid artery intima-media thickness was measured via computer software regarding far-wall method in both common carotid arteries. Maximum and mean CIMT values were compared between the two groups. The accuracy of CIMT in the prediction of slow coronary flow was estimated using Receiver Operating Characteristic curve (ROC) analysis. RESULTS: Maximum and mean CIMT values were 0.814+/-0.106 mm and 0.668+/-0.080 mm for normal flow group and 0.966+/-0.133 mm, 0.780+/-0.105 mm for slow flow group, respectively (p<0.001). Using 0.861 as the cut-off value for maximum CIMT positive and negative predictive values of slow flow were 80.1% and 70.2% (area under the ROC curve=0.809; p<0.001; 95% CI 0.750-0.868). CONCLUSIONS: We find out that CIMT and CTFC are strongly correlated. This implies that slow coronary flow could be an early marker of subclinical atherosclerosis. So patients with slow flow should be followed-up prospectively for possibility of manifest atherosclerosis.

Obstructive metastatic malignant melanoma of the heart: Imminent pulmonary arterial occlusion caused by right ventricular metastasis with unknown origin of the primary tumor.

Whether primary or metastatic, cardiac neoplastic diseases are relatively uncommon disorders. Although any malignancy may involve the heart, malignant melanoma (MM) has a significant tendency to metastasize to the heart. Cardiac involvement may occur during the course of MM or years after surgical therapy, but rarely metastasis may be the initial manifestation of the disease. This article reports a metastatic MM case that was initially manifested by heart failure symptoms because of right ventricle outflow obstruction and for which the primary focus could not be determined.

Non alcoholic steatohepatitis is associated with subclinical impairment in left ventricular function measured by speckle tracking echocardiography.

OBJECTIVE: Nonalcoholic steatohepatitis (NASH) is a part of histological spectrum of nonalcoholic fatty liver disease (NAFLD). Higher incidence of cardiovascular mortality has been reported in studies including patients with NAFLD. Impaired myocardial function can be detected by a novel echocardiographic method called speckle tracking echocardiography (STE) when conventional methods were normal. METHODS: Twenty-eight biopsy-proven NASH patients (mean age 41.6 ± 9.8, 16 male) without hypertension and diabetes mellitus were included in study. All patients underwent transthoracic echocardiography. Offline analyses of images was performed and strain (S), strain rate (SR) parameters compared between NASH patients and controls. Statistical analysis were done by independent samples t test between groups and a multiple linear regression model was used to identify the statistical significance of relationships between selected variables. RESULTS: R(SR-S) values were similar but R(S), R(SR-E), R(SR-E/A) values were significantly lower and R(SR-A) was higher in the NASH patients. There were no significant differences in CS, C(SR-S), C(SR-E), C(SR-A) and C(SR-E/A) values among the two groups. The most impressive results were obtained from longitudinal strain and strain rate parameters. LS, L(SR-S), L(SR-E), L(SR-A), values were significantly lower in NASH group when compared with healty controls. Linear regression analysis showed that RS and LS was not associated with diastolic blood pressure, total cholesterol and LDL cholesterol. CONCLUSION: The LV longitudinal and radial systolic functions may be deteriorated in patients with NASH even in the absence of apparent decrease in the LV ejection fraction. STE may be useful in detecting preclinical LV impairment in patients with NASH.
