Systematic review of patients presenting with suspected myocardial infarction and nonobstructive coronary arteries.

abstract：BACKGROUND:Tumor necrosis factor-alpha (TNF-alpha) and angiotensin II (Ang II) modulate heart failure in part by provoking the hypertrophic response. Signal transduction pathways of those factors are implicated in reactive oxygen intermediates (ROIs). Therefore, we hypothesized that TNF-alpha and Ang II might cause myo...
