Dyspnea predicts mortality among patients undergoing coronary computed tomographic angiography
We examined features associated with incident mortality risk among individuals undergoing coronary computed tomographic angiography (CCTA) presenting with dyspnea, typical angina, and neither of these symptoms. 1147 consecutive individuals without known CAD (mean 61 years, 61.6 % men) undergoing CCTA comprised the study population 132 with dyspnea, 218 with typical angina, and 797 without dyspnea or typical angina (reference group). Mortality risk in relation to dyspnea or typical angina was evaluated with multivariable Cox proportional hazards models compared to reference. In addition, the prognosis associated with dyspnea or typical angina was assessed among age-matched subgroups. Patients with dyspnea had a greater prevalence of ≥70 % stenosis (p
CONCLUSION: Macular edema is the principal cause of visual acuity decline in retinal vein occlusions; its prognosis is similar to that of retinal venous occlusions in general, hampered by the possibility of ischemic conversion. The diagnosis of retinal vein occlusion is clinical and does not require angiography. This remains, however, a useful exam to better analyze the retinal periphery as well as for the detection of various modalities during spontaneous progression.

ConclusionsThe FAVOR III China study will be the first randomized trial to examine the effectiveness and cost-effectiveness of a QFR-guided versus an angiography-guided PCI strategy in CAD patients.
Authors: Wang H, Liu Z, Shen Z, Fang L, Zhang S Abstract OBJECTIVES: To identify the predictors of coronary involvement, and to determine the impact of coronary involvement on long-term outcomes in patients with Takayasu's arteritis (TAK). METHODS: This retrospective cohort study of TAK patients with coronary evaluation by angiography or computed tomography angiography was conducted in a tertiary center between 1990 and 2018. Risk factors for coronary involvement and predictors of overall survival, cardiovascular event-free survival, and relapse-free survival were investigated. RESULTS: The median follow-up...
Recurrent cerebral infarctions associated with post-internal carotid artery dissection are a disabling complication of aortic dissection, which sometimes occur even without the progression of the aortic or internal carotid dissection . Accurate assessment of the dynamics of cervical blood flow is essential for the detection of blood stagnation and the prevention of delayed recurrent infarctions with appropriate anticoagulant therapy. Complicated flow due to interconnections of dissected lumens is a substantial constraint to accurate blood flow assessment; however, catheter angiography of the dissected artery is contraindicated.
To compare clinical characteristics and treatment outcomes of intraarterial thrombectomy (IAT) in acute basilar artery occlusion (BAO) with and without underlying intracranial atherosclerotic stenosis (ICAS) and to investigate the usefulness of preprocedural CT angiography findings in the diagnosis of ICAS.

AbstractBackgroundPituitary adenylate cyclase-activating polypeptide-38 (PACAP38) induces headache in healthy volunteers but the precise mechanisms by which PACAP38 leads to headache are unclear. We investigated the headache preventive effect of sumatriptan and ketorolac on PACAP38-induced headache in healthy volunteers. In addition, we explored contribution of vascular mechanisms to PACAP38-induced headache using high resolution magnetic resonance angiography.MethodsThirty-four healthy volunteers were divided in two groups (A and B) and received infusion of PACAP38 (10 picomol/kg/min) over 20 min. Group A was pret...
ConclusionCovered stent placement is a safe and effective alternative for treating HAP patients with high risk of severe complications after hepatic artery embolization. Larger stent grafts (> 4 mm in diameter) may achieve better prognosis.
Background: There is conflicting data on the effect of carotid revascularization on cognitive function. Objective: To examine cerebral blood flow and cognitive function after carotid revascularization. Methods: Patients with unilateral, asymptomatic hemodynamically significant carotid artery stenosis (80% by computed tomography angiography or magnetic resonance angiography) were eligible. Cerebral blood flow was measured preoperatively and 1 month postoperatively using quantitative phase contrast magnetic resonance angiography.
CONCLUSION: Percutaneous rheolytic thrombectomy is safe and effective for thrombosed arteriovenous grafts, with acceptable primary and secondary patency rates. Higher clinical success was found in patients never treated before and when the procedure was carried out within 24 h from the clinical onset of thrombosis.
