More than 1.2 million percutaneous coronary interventions are performed annually in the United States, with only an estimated 33% performed in women, despite the established benefits of percutaneous coronary intervention and adjunctive pharmacotherapy in reducing fatal and nonfatal ischemic complications in acute myocardial infarction and high-risk acute(More)
Reuse of electrophysiology catheters is an important cost-saving option for many laboratories. However, to be reused safely, catheters must undergo resterilization with ethylene oxide (EtO). Residual EtO levels on resterilized catheters may be high and could pose a risk to patients. Resterilized diagnostic electrophysiology catheters were tested for(More)
To learn whether neurophysiological taste responses change during structural development of the gustatory system, we recorded from the chorda tympani nerve in rats aged 7 to 92 days after birth. Chemical stimuli applied to the anterior tongue included four monochloride salts, two acids, sucrose, and urea. Responses to all chemicals were obtained as early as(More)
Pe ercutaneous transluminal coronary angioplasty (PTCA) has become a successful and widely used treatment for patients with coronary disease since its first clinical application byAndreas Gruentzig in 1977. Despite the increase in procedure and case complexity, primary success rates have improved. However, late restenosis, which constitutes the most(More)
Normotensive adults on low-sodium, weight-loss, and control diets recorded preferences and perceived saltiness for sodium chloride (NaCl) added to cream soup at intervals over 1 yr. Reduction in sodium intake and excretion accompanied a shift in preference toward less salt: preferred concentrations by ad libitum salting declined from 0.72% at the onset to(More)
Management of in-stent restenosis has become a significant challenge in interventional cardiology. The results of balloon angioplasty have been disappointing due to the high recurrence of restenosis at follow-up. Debulking of the restenotic tissue within the stents using directional coronary atherectomy (DCA) may offer a therapeutic advantage. We report the(More)
ST elevation is usually treated in cardiac catheterization laboratory with an aim for myocardial salvage by restoration of adequate coronary blood flow enhancing both early and long-term survival. Maximum benefit is achieved if therapy is initiated in the first hour after treatment onset, thus ushering the concept of door-to-balloon time. We present an(More)
