Ultrasonic evaluation of the intima-media thickness in the common carotid artery (IMT-CCA) has been widely used as a marker of atherosclerosis. However, the definition of IMT-CCA is not uniform and it includes two quite different pathological changes; a general intima-media thickening and a local atherosclerotic change (plaque formation). The aim of this paper was to evaluate the IMT-CCA and lo...

BACKGROUND/OBJECTIVES Carotid intimal media thickness (IMT) and coronary calcium scores (CCS) are thought to reflect atherosclerotic burden. The validity of this assumption for IMT is challenged by recent meta-analyses; for CCS by absence of a relationship between negative scores, and freedom of future events. As such, we considered evaluation of the relationship between tissue IMT and CCS, and...

BACKGROUND AND PURPOSE Higher plasma concentrations of the endogenous nitric oxides synthase inhibitor asymmetrical dimethylarginine (ADMA) are associated with increased risk of cardiovascular and cerebrovascular events and death, presumably by promoting endothelial dysfunction and subclinical atherosclerosis. We hypothesized that plasma ADMA concentrations are positively related to common caro...

PURPOSE To evaluate clinical outcomes of first-line immunomodulatory therapy (IMT) and prednisone alone or late IMT in Vogt-Koyanagi-Harada disease. METHODS Retrospective cohort study of 152 patients with Vogt-Koyanagi-Harada disease evaluated in a referral uveitis clinic in Chile from 1985 to 2011. Medical records of these patients were reviewed. Demographic data, clinical evaluation, type o...

We examined whether hypertrophy of the carotid artery in patients with untreated essential hypertension is associated with compensatory carotid artery enlargement as these patients age. Carotid ultrasonography was evaluated in 163 patients with untreated essential hypertension (74 males and 89 females) and in 76 normotensive subjects. Intima-media end-diastolic thickness (IMT) and outer vessel ...

BACKGROUND Increased carotid intimal-medial thickness (IMT) and coronary artery calcification (CAC) are used as 2 markers of early atherosclerosis. Our objectives were to assess whether increased IMT and CAC are related and to determine the relationship between cardiovascular risk factors and carotid IMT in young adults. METHODS AND RESULTS A sample of 182 men and 136 women aged 33 to 42 year...

OBJECTIVE To assess the relationship between breast arterial calcification (BAC) detected on screening mammography and atherosclerosis of carotid arteries considering the most likely involved layer of the arterial wall. MATERIALS AND METHODS A total of 537 consecutive women who underwent screening mammography were enrolled in this study. Seventy-nine subjects having BAC, aged 46-75 years, and...

BACKGROUND AND PURPOSE Carotid intima-media thickness (IMT) is a quantitative measure of subclinical atherosclerosis that is predictive of subsequent myocardial infarction and stroke. There is controversy regarding the proportion of variability in IMT explained by genetic factors. Thus, it is uncertain whether carotid IMT is a heritable trait that can be used in genetic studies. METHODS From ...

In patients with chronic obstructive pulmonary disease (COPD) the intensity of aerobic training is limited by dyspnea. Improving strength of the inspiratory muscles could enhance aerobic exercise training by reducing exercise-related dyspnea. We examined effects of home-based inspiratory muscle training (IMT) and cycle ergometry training (CET) in 53 patients with moderate to severe COPD (FEV(1)...

Many clinical studies support the opinion that carotid intima-media thickness (IMT) assessed by B-mode ultrasound in extracranial carotid arteries, either in a single segment (common carotid) or in multiple segments (aggregate of measures in common carotids, bifurcations, and internal carotids), is a valuable mirror of coronary risk status and a worthwhile predictor of subsequent coronary heart...
