Repolarization alternans has been considered a strong marker of electrical instability. The objective of this study was to investigate the hypothesis that ischemia-induced contrasting effects on the kinetics of membrane voltage and intracellular calcium transient (Ca(i)T) can explain the vulnerability of the ischemic heart to repolarization alternans.(More)
BACKGROUND The correlation between spontaneous calcium oscillations (S-CaOs) and arrhythmogenesis has been investigated in a number of theoretical and experimental in vitro models. There is an obvious lack of studies that directly investigate how the kinetics of S-CaOs correlates with a specific arrhythmia in the in vivo heart. OBJECTIVES The purpose of(More)
Water immersion-induced skin wrinkling (WISW) is dependent on intact peripheral sympathetic function. WISW was hypothesized to reflect autonomic function in subjects without peripheral neuropathy. We prospectively studied 70 healthy subjects (aged 31 ± 8 years, 63% females) without cardiovascular risk factors or neurological disease. All subjects underwent(More)
Obesity is an epidemic in the United States. It is an independent risk factor for cardiovascular diseases and associated with reduced life expectancy. The adverse effects are related to direct impact of obesity on cardiovascular system and indirectly through its influence on risk factors. Excessive accumulation of adipose tissue in the myocardium leads to(More)
TO THE EDITOR: I read Detsky and Gropper's commentary (1) with great interest and would like to present a counterargument. There is, perhaps, consensus that—within the department—researchers, section chiefs, chairs, and others in administrative roles will participate in clinical practice. I also stipulate that some participation in professional societies,(More)
OBJECTIVES To evaluate the clinical utility of and demand for the creatine kinase (CK)-MB assay. METHODS We examined the number of CK-MB tests from 2007 through 2013 while we progressively deemphasized their use. We first removed CK-MB from the acute coronary syndrome (ACS) panel and then from the main menu and observed the demand for the test. We also(More)
Coronary artery disease is a major cause of morbidity and mortality in patients with diabetes mellitus and remains one of the largest burdens on health care resources. Prevalence of asymptomatic CAD in this population is high and poses a diagnostic challenge due to lack of overt clinical complaints. At this time there is no clear algorithm to screen for(More)
Pulmonary vein thrombosis (PVT) is a rarely encountered disease entity with varied clinical presentations. It is usually associated with lung carcinoma, lung surgeries and as a complication of the radiofrequency catheter ablation procedure for atrial fibrillation. Its clinical manifestations can vary from mild hemoptysis to lung infarction with hemodynamic(More)
Myocardial infarction is the most common cause of ventricular arrhythmias. Although there have been several improvements and refinements in coronary catheterisation with percutaneous intervention over the years, this intervention is still rarely considered during active ongoing resuscitation of patients, especially in cases of persistent ventricular(More)
Percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) are established modalities of coronary revascularization. Choosing between the two requires taking into consideration not only disease severity, patient characteristics, and expected outcomes but also adverse effects. One such adverse effect is acute kidney injury (AKI),(More)
