However, these associations remain understudied in the literature. This study aims to characterize the prevalence and distribution of extracoronary arteriopathies in a large cohort of SCAD patients. Patients diagnosed with SCAD were extracted from 2018 to 2024. Baseline characteristics and comorbidities were collected. Available vascular imaging, including echocardiograms, computed tomography, and magnetic resonance, were used to assess for extracoronary arteriopathies. The prevalence and location of FMD, aneurysms, and dissections in extracoronary vascular beds were documented. Among 1,380 SCAD patients, 564 (40.9%) were found to have FMD, 166 (12.0%) had extra-coronary arterial dissections, and 228 (16.5%) had aneurysms in at least 1 extracoronary vascular bed. The most common sites of FMD were renal, carotid, vertebral, and iliac/femoral arteries. Aneurysms were most frequently located in cerebral, carotid, renal, and splenic arteries. Dissections were most prevalent in the carotid, vertebral, extremity, and celiac arteries. Thoracic aortic aneurysms were rare, with only 4 patients showing thoracic aortic dissection. Extracoronary arteriopathies are prevalent in patients with SCAD, affecting more than 47% of the cohort described here. These findings underscore the importance of comprehensive vascular imaging in patients with SCAD to detect extracoronary vascular abnormalities, which may have implications for surveillance and management strategies.</p>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":" ","pages":"151-157"},"PeriodicalIF":2.1,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to evaluate the relationship between angiographic stenosis severity (diameter stenosis, DS%), lesion location and morphologic characteristics and gold-standard pressure indices in patients with intermediate LMCA stenosis. We analyzed 34 patients with angiographically intermediate (25%-65%) LMCA stenosis who underwent intravascular ultrasound (IVUS) imaging and pressure wire assessment. Plaque burden, minimal lumen area (MLA), lesion location, and calcification were documented, and their relationships with FFR and iFR were evaluated. The iFR (r = -0.507 p < 0.001) and FFR (r = -0.383 p = 0.002) were only moderately correlated with DS%. FFR (r = 0.835, p < 0.001) and iFR (r = 0.769, p < 0.001) were significantly correlated with MLA. Presence of calcification partially blunted the correlation between structural and functional parameters. The receiver operating characteristic (ROC) curve showed the highest area under the curve (AUC) for FFR in detecting an MLA<6 mm², with a negative predictive value (NPV) of 80% and a positive predictive value (PPV) of 100%. All lesions with an MLA<6mm² (n = 16) had an FFR <0.80 whereas iFR >0.89 deferred 37% of these lesions. In conclusion, angiographic percent stenosis is an unreliable indicator of hemodynamic significance in intermediate LMCA disease; given that iFR has a high false-negative rate for lesions with MLA <6 mm² despite correlating with MLA, FFR may therefore be a more suitable index for evaluating intermediate LMCA stenoses, and further studies should refine cutoffs for nonhyperemic indices and investigate their clinical implications.</p>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":" ","pages":"143-150"},"PeriodicalIF":2.1,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145005711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this crisis, donation after circulatory death (DCD) is an emerging alternative to the traditional donation after brain death (DBD). Unfortunately, there is scarce data on HTx outcomes for this donation type, particularly within the United States; our investigation seeks to address this knowledge gap. As part of this study, the UNOS thoracic database was analyzed for first-time, adult, isolated orthotopic HTx recipients between 2019 and 2023. Patients were stratified into 3 groups: DBD, DCD III, and DCD IV. Further subgroup analysis for DCD III donors was conducted based on the procurement method, direct procurement and perfusion (DPP) or normothermic regional perfusion (NRP). After creating the sample cohort, a total of 14,035 HTx recipients were included in our analysis (DBD 86.5%, DCD III 6.9%, DCD IV 6.5%). There was an exponential increase in the number of DCD III cases and HTx centers that offer this donation type during the study period. DCD III recipients had a higher incidence of postoperative dialysis use; otherwise, all 3 groups shared similar rates of postoperative permanent pacemaker placement and stroke, acute rejection, and mortality. Within DCD III recipients, DPP and NRP procurement techniques had similar survival. To conclude, although DCD III was associated with an increased incidence of postoperative dialysis use, both DCD type III and IV had comparable morbidity and survival as the standard of care DBD donors. Overall, our investigation provides encouraging data to support DCD use as a safe option to increase the limited donor pool in the United States.</div></div>","PeriodicalId":7705,"journal":{"name":"American Journal of Cardiology","volume":"258 ","pages":"Pages 83-88"},"PeriodicalIF":2.1,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 4,074 patients with AMI and TIMI thrombus grades 4 or 5 who underwent aspiration thrombectomy were selected, of whom 892 patients (21.9%) received IVI-guided PCI and 3,182 patients (78.1%) received angiography-guided PCI. Primary outcome was major adverse cardiovascular event (MACE, a composite of all-cause death, MI, repeat revascularization, and stent thrombosis). Major secondary efficacy outcome was cardiac death and safety outcome was stroke at 3 years. During the median 3 years of follow-up, the risk of MACE was significantly lower in the IVI-guided PCI group than in the angiography-guided PCI group (12.9% vs 16.3%; adjusted HR, 0.80; 95% CI, 0.65 to 0.98; p = 0.035), mainly driven by a lower risk of all-cause death (5.7% vs 10.0%; adjusted HR, 0.65; 95% CI, 0.48 to 0.89; p = 0.007).
