163 Objectives: Obstructive sleep apnea (OSA) is an emerging risk factor for cardiovascular
disease. Microcirculatory dysfunction has been proposed as a potential mechanism in the …

376 Objectives Obstructive sleep apnea (OSA) is associated with an increased risk of
cardiovascular diseases. Endothelial dysfunction could be one of the pathophysiological …

2461 Introduction: Epidemiologic studies have established an association between markers
of obstructive sleep apnea (OSA) severity and cardiovascular disease (CVD). Coronary …

P1183 Introduction: Diastolic dysfunction is common in persons with obstructive sleep
apnea (OSA). There is mounting evidence suggesting that reduction in left ventricular (LV) …

Patients with severe obstructive sleep apnea (OSA) are less able to increase blood flow to
the heart when needed, according to a first-of-its-kind PET imaging study presented at the …

Background: Obstructive sleep apnea (OSA) is associated with right ventricular (RV)
remodeling, RV dysfunction and pulmonary hypertension. Myocardial flow reserve (MFR) …

Objectives We hypothesized that anginal patients with low coronary flow reserve (CFR)
could have variable clinical features according to resting myocardial blood flow (MBF) …

Obstructive sleep apnea (OSA) is a common disorder that is associated with adverse
cardiovascular disease (CVD)-related outcomes. 1 The pathogenetic mechanisms of CVD in …

385 Objectives PET allows absolute quantification of MBF. Changes in MBF during rest and
pharmacological stress can identify coronary artery dysfunction caused by atherosclerotic …

Purpose: $^{13} N $-ammonia is a well known radiopharmaceutical for the measurement of
a myocardial blood flow (MBF) non-invasively using PET-CT. In this study, we investigated a …
