Elastin fragmentation in atherosclerotic mice leads to intraplaque neovascularization, plaque rupture, myocardial infarction, stroke, and sudden death

Conclusions Elastin fragmentation plays a key role in plaque destabilization and rupture. ApoE–/–Fbn1C1039G+/– mice represent a unique model of acute plaque rupture with human-like complications.

Authors: Wang HY, Gao RL, Xu B, Yang YJ, Yin D, Wang Y, Dou KF Abstract The benefits and harms of dual antiplatelet therapy (DAPT) continuation with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for high ischemic or bleeding risk patients remain unclear. All consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry from January 2013 to December 2013. We evaluated 7521 patients who were at high risk for thrombotic or hemorrhagic complications and were events free at 1 year after the index procedure. &quo...

AbstractDirect stenting (DS) without pre-dilatation of the culprit lesion might improve myocardial perfusion and prognosis in patients undergoing percutaneous coronary intervention for ST-elevation myocardial infarction (STEMI); however, some studies report conflicting results. We investigated whether DS provides incremental myocardial benefits over conventional stenting (CS) in STEMI patients based on cardiac magnetic resonance imaging (CMR) measures. Reperfused patients who underwent CMR examinations within 1  week of STEMI onset were selected from a multicenter CMR registry of STEMI (NCT: 03768453). Patients were s...

Conclusion: Some cases with CCI treated with IV-tPA and endovascular intervention were reported, but the treatment strategy should be still discussed multidisciplinary. Especially, the administration of antithrombotic drugs for CCI should be carefully performed because fatal hemorrhage such as cardiac tamponade can occur. PMID: 31893142 [PubMed]

Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

A 60-something presented with hypotension, bradycardia, chest pain and back pain.She had a h/o aortic aneurysm, aortic insufficiency, peripheral vascular disease, and hypertension.  She had a mechanical aortic valve.  She was on anti-hypertensives including atenolol, and on coumadin, with an INR of 2.3. She was ill appearing.  BP was 70/49, pulse 60.A bedside echo showed good ejection fraction and normal right ventricle and no pericardial fluid. Here is the initial ECG:What do you think?This ECG actually looks like a left main occlusion (which rarely presents to the ED alive):  ST Elevation in...

ConclusionIn patients with RSNOFC, CEA may be considered a potential treatment option. Although procedural risks in this small subgroup may be higher as compared to patients with low-to-moderate risk anatomy, this risk may outbalance the natural course.
