Late Gadolinium Enhancement (LGE) pattern of cardiac amyloidosis (CA) at cardiac magnetic resonance (CMR) examination is absent in approximately 30 % of patients. We tested whether the evaluation of myocardial gadolinium signal intensity (SI) decay (SID) has a higher diagnostic accuracy for CA. CMR was performed in 59 patients with systemic AL amyloidosis (36 males, 69 ± 10 years, mean ± SD), and 20 age/sex-matched healthy controls. LGE images were acquired every minute up to 8 min after gadolinium injection (time of inversion 250 ms). SI regions of interest were plotted in SI/time curves for endocardial (Endo) and epicardial layer of interventricular septum, cavity, and skeletal muscle as reference. SID (a negative exponential function described by the parameter TSID) was expressed as number of heart beats (HB) from each ROI. The typical LGE pattern for CA was detected in 42 patients (Ty-LGE), while 17 showed either absent LGE or an atypical pattern (ATy-LGE). A definite CA diagnosis was confirmed in all Ty-LGE patients and in 10/17 ATy-LGE patients. At ROC analysis Endo-TSID was the most accurate parameter to distinguish Ty-LGE and ATy-LGE patients from controls. A 269 HB threshold (mean + 2 SD Endo-TSID measured in controls) identified 51/52 patients with definite CA diagnosis, with 98 % sensitivity, 93 % specificity, and 96 % diagnostic accuracy. A direct relation was found between the extracellular volume and Endo-TSID in CA patients (r 0.72, 95 % CI 0.37–089, p < 0.001). the analysis of myocardial SID after gadolinium injection improves the accuracy of CMR for CA diagnosis. 相似文献

A method for sample preparation and high-performance liquid chromatography detection and quantification has been developed for the routine analysis of psoralen and bergapten, photosensitizing compounds, in topic solutions employed in Brazil for treatment of vitiligo and psoriasis. The linearity, accuracy, the inter- and intra-day precision of the procedure were evaluated. The calibration curve for psoralen and bergapten were linear in the range 1.0-20.0 microg ml(-1). The best recoveries of the psoralens in the topic solutions analysed were 96.3-98.2%. The percentage coefficient of variation of the quantitative analysis of the psoralens in the product analyses was within 5%. 相似文献

Late stent thrombosis represents a life-threatening event, usually triggered by inadequate antiplatelet therapy and promoted by multiple risk factors, such as stenting of a chronic total occlusion, overlapping stenting, an abnormal vascular response to the eluted drug, stent malapposition and stent fracture. A 57-year-old man with aspirin hypersensitivity underwent successful percutaneous revascularization of a chronic total occlusion of the left anterior descending artery (LAD). He received two sirolimus-eluting stents overlapping for 2 mm and was discharged on clopidogrel and picotamide. Two years later, 15 days after clopidogrel discontinuation, he experienced an anterior ST-segment elevation myocardial infarction and underwent rescue percutaneous LAD thrombectomy after unsuccessful fibrinolysis. Coronary angiography showed fracture of the distal stent, with a 5 mm gap between the two portions, as well as severe late stent malapposition, confirmed by optical coherence tomography. Despite treatment with clopidogrel and picotamide, in the following days the patient experienced two new episodes of stent thrombosis, treated with thrombectomy and deployment of bioengineered stents. The patient underwent successful oral aspirin desensitization, with a complete in vitro inhibition of platelet function, and was discharged on aspirin, clopidogrel and warfarin, without experiencing other events at 6-month follow-up. 相似文献
