Additional diagnostic value of new CT imaging techniques for the functional assessment of coronary artery disease: a meta-analysis.

Objectives: To determine the diagnostic performance of cardiac computed tomography (CT)-based modalities including coronary CT angiography (CTA), stress myocardial CT perfusion (stress CTP), computer simulation of fractional flow reserve by CT (FFR), and transluminal attenuation gradients (TAG), for the diagnosis of hemodynamic significant coronary artery disease (CAD), using invasive fractional flow reserve as the reference standard.

Methods: PubMed and Cochrane databases were searched for original articles until July 2018. Diagnostic accuracy results were pooled at per-patient and per-vessel level using random effect models.

Coronary artery dissection in the puerperium: A case report and literature review.

Spontaneous coronary artery dissection is a rare but important cause of acute coronary syndrome. Its relevance for women during the puerperium mandates awareness and understanding amongst obstetric healthcare professionals. The aetiology of the increased risk in pregnancy has not been fully elucidated, but include medial eosinophilic angitis, pregnancy-induced degeneration of collagen in conjunction with the stresses of parturition, and rupture of the vasa vasorum.
