Background Preliminary semi-quantitative cardiovascular magnetic resonance (CMR) perfusion studies have demonstrated reduced myocardial perfusion reserve (MPR) in patients with angina and risk factors for microvascular disease (MVD), however fully quantitative CMR has not been studied. The purpose of this study is to evaluate whether fully quantitative CMR identifies reduced MPR in this population, and to investigate the relationship between epicardial atherosclerosis, left ventricular hypertrophy (LVH), extracellular volume (ECV), and perfusion. Methods Forty-six patients with typical angina and risk factors for MVD (females, or males with diabetes or metabolic syndrome) who had no obstructive coronary artery disease by coronary angiography and 20 healthy control subjects underwent regadenoson stress CMR perfusion imaging using a dual-sequence quantitative spiral pulse sequence to quantify MPR. Subjects also underwent T1 mapping to quantify ECV, and computed tomographic (CT) coronary calcium scoring to assess atherosclerosis burden. Results In patients with risk factors for MVD, both MPR (2.21 [1.95,2.69] vs. 2.93 [2.763.19], p

The Malcolm Baldrige National Quality Award was established in 1987. Although primarily an award for business and industry, pilot criteria for healthcare settings have been developed. These criteria can be used by healthcare organizations to conduct internal evaluations of their institutions. Benefi …

Nursing care provided to patients and their families should be based on strong scientific evidence. In the quantitative research paradigm, the highest level of evidence is derived from conclusive randomized controlled clinical trials. Multicenter clinical research allows the accrual of sufficient nu …

The aging population is a global phenomenon. The skyrocketing costs of healthcare and the shortage of healthcare providers will soon become a crucial issue all over the world. Taiwan's government executed the Taiwan's Telehealth Pilot Project (TTPP) from July 1, 2008 to December 31, 2008, using heal …
