Atherosclerosis evaluation by coronary computed tomography angiography (CCTA) is promising for artery disease (CAD) risk stratification, but time consuming and requires high expertise. Artificial Intelligence (AI) applied to CCTA comprehensive CAD assessment may overcome these limitations. We hypothesized AI aided analysis allows rapid, accurate of vessel morphology stenosis.This was a multi-site study 232 patients undergoing CCTA. Studies were analyzed FDA-cleared software service that...

Background: Hypertension frequently accompanies diabetes mellitus, worsening prognosis and complicating medical care for patients. Low medication adherence with multiple medications is a major factor in the inadequate achievement of blood pressure treatment goals. Widespread access to mobile phones offers new opportunity communicate patients enhance disease self-management. Methods: We recruited 50 high-risk urban hypertension, who are using at least two prescription into an open-label trial...

Noninvasive stress testing is commonly used for detection of coronary ischemia but possesses variable accuracy and may result in excessive health care costs. This study aimed to derive validate an artificial intelligence-guided quantitative computed tomography angiography (AI-QCT) model the diagnosis that integrates atherosclerosis vascular morphology measures (AI-QCTISCHEMIA) evaluate its prognostic utility major adverse cardiovascular events (MACE). A post hoc analysis CREDENCE (Computed...

BACKGROUND Activation of neurohumoral hormones or sulfhydryl group depletion may contribute to the development nitroglycerin tolerance. In an attempt prevent nitrate tolerance, this study evaluated interaction with angiotensin converting enzyme (ACE) inhibitors and without a group. METHODS AND RESULTS Thirty-four subjects were randomized 7-day regimen enalapril 10 mg b.i.d., captopril 25 t.i.d., placebo. Venodilator response was assessed forearm plethysmography by measuring change in venous...

This paper suggests an alternative to the commonly-held "scarcity paradigm" of thinking about valued human resources, which assumes individuals must compete because resources are scarce. The alternative--the "synergy paradigm"--is empitomized in "synergistic community," where renewable and expanding, distributed equitably members, so that what is good for one all whole greater than sum its parts. Three field studies present cross-cultural evidence functioning empowerment within a synergistic...

The effects of encainide on ventricular arrhythmia and left function were studied in 21 patients with chronic, high-grade using a prospective, 3-month, placebo-controlled, single-blind trial design. Encainide caused 96% decrease the average hourly frequency premature complexes (VPCs) comparable reductions salvos nonsustained tachycardia (VT) episodes sustained VT. Intracardiac electrophysiologic testing showed prolonged intraatrial intraventricular conduction times increased atrial,...

Cell phone–assisted self-management of diabetes offers a new approach to improving chronic care; however, introducing this technology presents many challenges health care team. The George Washington University–District Columbia Phone Diabetes Project enrolled 32 patients with Type 2 from community clinic using patients' cell phones connected the Well Doc Manager System monitoring by case managers and monthly reports primary providers. Despite monetary incentives (cell phone rebates), dropout...
