How to study coronary microvascular dysfunction and its.
Introduction: Microcirculation dysfunction is a typical feature of systemic sclerosis (SSc) and represents the earliest abnormality of primary myocardial involvement. We assessed coronary microcirculation status by combining two functional tests in SSc patients and estimating its impact on disease outcome.

Coronary artery bypass grafting may be associated with several cardiac complications, including ischemia, acute myocardial infarction, arrhythmias, or hemodynamic instability. Accumulating evidence suggests that well-developed coronary collateral circulation may protect against adverse effects, including myocardial ischemia. Assessment of myocardial microvascular perfusion is, therefore, of.
Objectives The purpose of this study was to characterize the hemodynamic force acting on plaque and to investigate its relationship with lesion geometry. Background Coronary plaque rupture occurs when plaque stress exceeds plaque strength. Methods Computational fluid dynamics was applied to 114 lesions (81 patients) from coronary computed tomography angiography.
Historically much of our understanding of the coronary circulation has been centered towards the epicardial vessels. However, recent work has highlighted the importance of the coronary microcirculation across a broad spectrum of clinical conditions in influencing patient outcomes. Therefore an ability to measure microvascular function is most valuable.
