CONCLUSIONS: MMD-associated aneurysms occurred in 3.3% of the MMD cohort in this study, of which 63.6% were major-artery aneurysms and 36.4% were non-major-artery aneurysms. The major-artery group included 17.9% that became angiographically worse, while 31.2% were growing or hemorrhaging in the non-major-artery group. PMID: 33029969 [PubMed]
We present the case of limb ischemia secondary to accidental intra-arterial buprenorphine/naloxone film injection successfully treated with sublingual nitroglycerin. A 39-year-old man with history of intravenous drug use presented sudden severe left hand pain since three days prior to evaluation. Pain was preceded by self-injection of dissolved buprenorphine/naloxone sublingual film onto the affected arm. An arteriogram suggested severe vasoconstriction in the absence of frank thrombosis. Patient was initially treated with continuous heparin infusion and nifedipine. Forty-eight hours later, due to poor response, sublingual...

ConclusionsThe lowered MD index early after mechanical recanalization without BGC usage can be interpreted as microstructural ischemic damage of the salvaged penumbra. It was shown that achieving complete reperfusion in a setting of BGC usage with proximal flow arrest minimizes penumbral damage and improves long-term outcomes.Key Points• Microstructural ischemic damage can be reduced by using proximal flow arrest during endovascular treatment with balloon guide catheter.• Complete reperfusion in a setting of balloon guide catheter minimizes penumbral damage and improves long-term outcome.
AbstractThe role of drug-coated balloons (DCBs) in patients with acute myocardial infarction (AMI) remains controversial. We performed a meta-analysis of all published studies comparing the outcomes of DCBs vs. stenting in AMI patients. Four studies with 497 patients (534 lesions) were included (three randomized controlled trials and one observational study). During a mean follow-up of 9 months (range 6–12 months), DCBs were associated with similar risk of major adverse cardiovascular events (5% vs. 4.4%; OR 1.24, 95% CI: [0.34, 4.51],p = 0.74,I2 = 35%), all-cause mortality (0.0...
Higher pericoronary adipose tissue (PCAT) attenuation, a novel marker of inflammation in coronary CT angiography (CTA), has been shown to indicate increased cardiac mortality. Supplementation of eicosapentaenoic acid (EPA) has been shown to decrease cardiovascular death. Whether blood levels of n-3 fatty acids are associated with differences in PCAT attenuation is unknown.

Authors: Ling Y, Tang S, Cao Y, Fu C Abstract Background: Increasing evidence states that the plasma lipoprotein-associated phospholipase A2 (Lp-PLA2) levels and apolipoprotein particles are regarded as the risk maker for cardiovascular heart disease. Nevertheless, the issue about whether Lp-PLA2 is associated with apolipoprotein particles in individuals who have been diagnosed as stable coronary artery disease (CAD) remains largely unexplored. Method: All 569 participants engaged in this research, who never took lipid-lowering drugs, had been divided into groups by the coronary angiography (CAG), namely, stabl...
Conclusion: Although the anatomical results of repeated surgeries of FTMH with ILM plug are favorable, visual function results may be limited. Secondary closure of FTMH with ILM plug may lead to atrophy, changes in the macular vasculature, and eccentric fixation. The trial is registered with NCT03701542. PMID: 33029387 [PubMed]
