Background-We have sometimes noted abnormal angiographic coronary dilatation, <50% of the reference vessel, at the site of sirolimus-eluting stent implantation, suggesting contrast staining outside the stent struts and named this finding peri-stent contrast staining (PSS
Myocarditis is an adverse event associated with coronavirus disease 2019 (COVID-19) mRNA vaccination. A 50-year-old man presented with dyspnea and resting chest pain after receiving the second dose of the COVID-19 mRNA vaccine and developed cardiogenic shock. Fulminant myocarditis was diagnosed by endomyocardial biopsy and treated with intravenous corticosteroids.
SummaryA relationship between serum polyunsaturated fatty acids (PUFAs) and cardiovascular disease has been reported; however, the existence of a relationship between serum PUFAs and extent of vessel disease (VD) in patients with ST elevation myocardial infarction (STEMI) remains unclear.Between July 2011 and June 2015, 866 consecutive STEMI patients underwent emergent percutaneous coronary intervention, 507 of whom were enrolled and classified into three groups according to the initial angiograms: 1VD, 294 patients; 2VD, 110 patients; and 3VD/left main trunk disease (LMTD), 103 patients. Serum levels of PUFAs, including eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid, and other laboratory data during hospitalization were evaluated.The serum EPA level in the 3VD/LMTD group was significantly lower than that in the 1VD group (55.5 ± 22.1 versus 66.2 ± 28.7, P = 0.002) and was slightly lower than that in the 2VD group (55.5 ± 22.1 versus 65.2 ± 28.9, P = 0.0167). Multivariate adjustment analysis revealed that age !70 years (odds ratio, 1.72; 95% confidence interval, 1.03-2.89; P = 0.038) and a low serum EPA level (odds ratio, 0.98; 95% confidence interval, 0.99-1.00; P = 0.023) were independent risk factors for 3VD/LMTD, while a low serum DHA level was not.A low serum EPA level may be more strongly related than a low serum DHA level to the extent of VD in STEMI patients. Age !70 years and a low serum EPA level may be independent risk factors for 3VD/LMTD.(Int Heart J 2017; 58: 868-873) Key words: Eicosapentaenoic acid, Docosahexaenoic acid, Mulivessel disease, Acute coronary syndrome, Cardiovascular disease A n association between fish intake and risk of cardiovascular disease has been demonstrated in several epidemiological studies and clinical trials.
Background: Limited data are available with which to compare the clinical characteristics of patients with very late stent thrombosis (VLST) after drug-eluting stent (DES) or bare-metal stent (BMS) implantation. The purpose of this study was to investigate the differences in the characteristics of VLST after DES and BMS implantation by reviewing the clinical and angiographic data.
Methods and Results:A total of 28 patients (30 lesions) with VLST after DES implantation and 33 patients (33 lesions) with VLST after BMS implantation were identified. The occurrence of VLST after BMS implantation (2,647±996 days) was much later than that after DES implantation (1,194±558 days, P<0.001). The number of VLST after DES implantation increased gradually each year; however VLST after BMS implantation started to occur >50 months later, and its number increased subsequently. The prevalence of VLST related to surgical procedures involving discontinuation of antiplatelet therapy in VLST patients was higher after DES implantation (14.3%) than after BMS implantation (0%, P=0.039). Angiographic stent fracture was seen in 36.7% of VLST lesions after DES implantation at different times (464-2,102 days after procedure), while none was seen in VLST lesions after BMS implantation (P<0.001).
Conclusions:The timing of VLST was different after DES and BMS implantation. Stent fracture was a specific finding of VLST after DES implantation. (Circ J 2013; 77: 1453 -1460
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
