Coronary subclavian steal syndrome arises when a stenosis of the subclavian artery results in reduced antegrade or retrograde flow in an internal mammary artery with resultant coronary ischemia. This occurs in patients who have previously undergone surgical coronary revascularization utilizing an internal mammary artery graft. This syndrome can be(More)
Hypertrophic cardiomyopathy (HC) is characterized by impaired diastolic function and, in about 1/4 of patients, left ventricular (LV) outflow tract obstruction. Atrioventricular (AV) pacing diminishes LV outflow tract gradient in HC, but impairs diastolic function in the experimental animal and in different categories of patients. To investigate the effects(More)
Hypertrophic cardiomyopathy (HC) is characterized by impaired diastolic function, and left ventricular (LV) outflow tract obstruction in about one-fourth of patients. Verapamil improves diastolic properties, but may have dangerous adverse effects. This study investigates the effects of diltiazem on hemodynamics and LV function in 16 patients with HC who(More)
Diastolic dysfunction is common in hypertrophic cardiomyopathy (HC). Previous studies suggest that Doppler transmitral flow velocity profiles, and the left atrial (LA) M-mode echogram can be used noninvasively to evaluate left ventricular (LV) diastolic function. However, this has not been proved in HC. In this study we determined the relation of Doppler(More)
Clinical outcome after percutaneous coronary intervention (PCI) is significantly worse in diabetic patients in comparison to nondiabetic patients. The subset of diabetic patients in the ARTS trial treated with multivessel stenting had the lowest 1-year event-free survival. We examined our experience of multivessel PCI in diabetics to assess clinical outcome(More)
Autonomic dysfunction has been reported in patients with hypertrophic cardiomyopathy. To evaluate the influence of different clinical and echocardiographic features of the disease on sympathovagal balance, as assessed by heart rate variability, 33 patients with hypertrophic cardiomyopathy and 33 healthy volunteers underwent echocardiographic examination and(More)
Inflammation is a critical pathogenic component in acute coronary syndromes. As a consequence the potential use of inflammatory markers as predictors of clinical outcome in acute coronary syndromes has been investigated. This review outlines the pathology underlying acute coronary syndromes and reviews the published data on inflammatory markers in acute(More)
