Thiazide diuretic agents lower the urinary excretion of calcium. Their use has been associated with increased bone density, but their role in preventing hip fracture has not been established. We prospectively studied the effect of thiazide diuretic agents on the incidence of hip fracture among 9518 men and women 65 years of age or older residing in three(More)
Restenosis remains an important issue even after coronary brachytherapy despite its efficacy in the treatment for in-stent restenosis. The acute and chronic changes in vascular wall are unique following brachytherapy. The restenotic tissue post coronary brachytherapy is relatively acellular and appears echolucent in intravascular ultrasound examination.(More)
This article reviews the safety and efficacy of ibutilide for use in patients with atrial fibrillation and flutter. Ibutilide, a class III antiarrhythmic agent, is primarily used for conversion of atrial flutter and fibrillation and is a good alternative to electrical cardioversion. Ibutilide has a conversion rate of up to 75% to 80% in recent-onset atrial(More)
Intracardiac echocardiography (ICE) broadens the spectrum of available echocardiographic techniques and provides the operator direct visualization of cardiac structures in real time. ICE has clear advantages over fluoroscopy, transthoracic echocardiography, and transesophageal echocardiography as the imaging modality of choice in the cardiac catheterization(More)
The effect on post-operative outcomes after coronary artery bypass graft (CABG) surgery is not clear. Among 17,812 patients who underwent CABG during October 1,2006-September 28,2012 in any Department of US Veterans Affairs (VA) hospital, we identified 5,968 with available preoperative urine albumin-creatinine ratio (UACR) measurements. We examined the(More)
CONTEXT Abnormalities in calcium metabolism may potentially contribute to the development of vascular disease. Calcium metabolism may be different in African American (AA) vs white individuals, but the effect of race on the association of serum calcium with clinical outcomes remains unclear. OBJECTIVE This study sought to examine race-specific(More)
Predicting segmental and global functional recovery of the left ventricle (LV) after an acute ST elevation myocardial infarction (STEMI) is challenging. The study published in this issue of this journal by Shehata shows the value of automated functional imaging of two-dimensional (2D) myocardial strain in predicting functional recovery of the LV after(More)
BACKGROUND Heart failure (HF) is associated with poor cardiac outcomes and mortality. It is not known whether HF leads to poor renal outcomes in patients with normal kidney function. We hypothesized that HF is associated with worse long-term renal outcomes. METHODS AND RESULTS Among 3 570 865 US veterans with estimated glomerular filtration rate (eGFR)(More)
