The incidence of stroke in patients with early echocardiography after acute myocardial infarction
AbstractLeft ventricular (LV) thrombus formation after ST-elevation myocardial infarction (STEMI) increases the risk of stroke. In our center, most echocardiograms are performed within 2  days post-STEMI. However, LV thrombi often become visible later. We assessed the 1-year incidence of stroke in patients without LV thrombus on echocardiography performed early (1–2 days) vs. later (day ≥ 3) post-STEMI. This retrospective observational study included 416 patients with acut e STEMI. Patients with atrial fibrillation were excluded. All patients underwent echocardiography during admission. Patients with stroke withi...

Intracranial Atherosclerotic Plaque Enhancement in Patients with Ischemic Stroke BRAIN
CONCLUSIONS: Strong pathologic enhancement of intracranial atherosclerotic plaque was seen in all patients imaged within 4 weeks of ischemic stroke in the vessel supplying the stroke territory. The strength and presence of enhancement of the atherosclerotic plaque decreased with increasing time after the ischemic event. These findings suggest a relationship between enhancing intracranial atherosclerotic plaque and acute ischemic stroke.

Impact of Implementing Cardiac CT in Evaluating Patients Suspected of Cardioembolic Stroke
Conclusions: Implementing cardiac CT in assessing patients suspected of cardioembolic stroke added value to echocardiographic evaluation, by detecting major embolic potential findings. In addition, cardiac CT revealed additional potentially significant stroke-unrelated findings and CAD.

Emergent extracranial internal carotid artery stenting and mechanical thrombectomy in acute ischaemic stroke.
CONCLUSIONS: Treatment of tandem extracranial ICA and intracranial occlusions in the setting of acute ischaemic stroke with extracranial carotid artery stenting followed by adjunctive intracranial mechanical thrombectomy is both safe and effective, but further evaluation of this treatment modality is necessary.

Echocardiographic parameters determining cardiovascular outcomes in patients after acute ischemic stroke
AbstractPrevious studies have focused on only 1 or 2 echocardiographic parameters as prognostic markers in patients with acute ischemic stroke (AIS). A total of 900 patients with AIS who underwent transthoracic echocardiography (72.6  ± 12.0 years and 60% males) were retrospectively reviewed. Composite clinical events, including all-cause mortality, non-fatal stroke, non-fatal myocardial infarction, and coronary revascularization, were assessed during clinical follow-ups. During a median follow-up of 3.3 years (interquart ile range 0.6–5.1 years), there were 151 (16.8%) composite events. In the multivariable anal...

A Review on Joint Carotid Intima-Media Thickness and Plaque Area Measurement in Ultrasound for Cardiovascular/Stroke Risk Monitoring: Artificial Intelligence Framework
This study reviews the modern and automated methods such as artificial intelligence (AI)-based. Machine learning (ML) and deep learning (DL) can provide automated techniques in the detection and measurement of cIMT and PA from carotid vascular images. Both ML and DL techniques are examples of supervised learning, i.e., learn from “ground truth” images and transformation of test images that are not part of the training. This review summarizes (1) the evolution and impact of the fast-changing AI technology on cIMT/PA measurement, (2) the mathematical representations of ML/DL methods, and (3) segmentation approaches for c...

Scoring flow restoration in cerebral angiograms after endovascular revascularization in acute ischemic stroke patients
Abstract Endovascular revascularization techniques are increasingly used to treat arterial occlusions in patients with acute ischemic stroke. To monitor and communicate treatment results, a valid, reproducible, and clinically relevant, yet easy to use grading scheme of arterial recanalization and tissue reperfusion for digital subtraction angiography is needed. An ideal scoring system would consider the target arterial lesion, the perfusion deficit, and the collateral status before treatment and measure recanalization, reperfusion, early venous shunting, vasospasm, as well as distal embolization after flow restora...

Outcomes of transcarotid artery revascularization: A systematic review
CONCLUSION: TCAR is associated with a lower risk of perioperative stroke compared to TFCAS. TCAR is also associated with shorter operative time, lower risk of CNI and less blood loss compared to CEA. TCAR may be a promising treatment option besides TFCAS and CEA.PMID:36039496 | DOI:10.1177/15910199221123283

Percutaneous coronary intervention versus coronary artery bypass graft for stable angina: Meta-regression of randomized trials
Conclusion: PCI significantly reduces the risk of stroke compared to CABG particularly in female patients: however the risk of revascularization is increased with PCI, especially in women and in those with diabetes.

Reduction in Total Cardiovascular Events With Ezetimibe/Simvastatin Post-Acute Coronary Syndrome The IMPROVE-IT Trial
ConclusionsLipid-lowering therapy with ezetimibe plus simvastatin improved clinical outcomes. Reductions in total PEP events, driven by reductions in MI and stroke, more than doubled the number of events prevented compared with examining only the first event. These data support continuation of intensive combination lipid-lowering therapy after an initial CV event.

Carotid Stenting without Embolic Protection Increases Major Adverse Events: Analysis of the National Surgical Quality Improvement Program INTERVENTIONAL
CONCLUSIONS: Lack of embolic protection device use during carotid artery stent placement is associated with a 4-fold increase in the likelihood of perioperative stroke. Nevertheless, nearly one-quarter of patients in the American College of Surgeons National Surgical Quality Improvement Program underwent unprotected carotid artery stent placement. Efforts targeting improved embolic protection device use during carotid artery stent placement are warranted.
