Prolonged Autonomic Fluctuation Derived from Parasympathetic Hypertonia after Carotid Endarterectomy but not Stenting

Carotid endarterectomy (CEA) is a standard treatment for carotid artery stenosis, but the incidence after periprocedural myocardial infarction (MI) is not negligible. The mechanism for the higher risk of MI following CEA compared with the carotid artery stenting (CAS) is unclear. We hypothesized that it may be explained by different autonomic nervous responses.

CONCLUSION: The perioperative use of β-blockers is a protective factor for post-carotid endarterectomy hypertension and contributes to stabilizing the postoperative peak systolic blood pressure three days after conventional endarterectomy. However, β-blockers might also lead to intraoperative hemodynamic depression, especially for patients with a low baseline heart rate. PMID: 32772840 [PubMed - as supplied by publisher]

Conclusions: Taken together, these results provide evidence that SMC-derived cells within advanced mouse and human atherosclerotic lesions exhibit far greater phenotypic plasticity than generally believed, with Klf4 regulating transition to multiple phenotypes including Lgals3+ osteogenic cells likely to be detrimental for late stage atherosclerosis plaque pathogenesis.

Patients undergoing carotid endarterectomy (CEA) often experience postoperative hemodynamic changes that require intravenous medications for hypo- and hypertension. Prior studies have found these changes to be associated with increased risks of 30-day mortality, stroke, myocardial infarction (MI), and length of stay (LOS). Our aim is to investigate preoperative risk factors associated with the need for postoperative intravenous medications for blood pressure control.

CONCLUSIONS: Heparin reversal with protamine sulfate after tibial or peroneal bypass grafting is not associated with higher cardiovascular morbidity, bypass thrombosis, amputation, or mortality. Additionally, there was no statistically significant difference in post-operative bleeding or thrombosis complications for patients who did not receive protamine, although the findings are suggestive of a potential difference in a more adequately powered study. Our results suggest that protamine sulfate is safe for intraoperative use without increased risk of thrombotic complications or early tibial bypass graft failure. PMID:...

A commonly held dictum is that carotid endarterectomy (CEA) and carotid artery stenting (CAS) are generally associated with minimal mortality and morbidity. This is supported by a multitude of studies demonstrating stroke rates approximating 1% and myocardial infarction of 2%-4%. However, this review of carotid revascularization in frail patients provides us with sobering results that have often been overlooked in our fixation on postprocedure stroke and myocardial infarction rates.1 Frail patients suffered 23.5% in-hospital complications, 5.2% died, and 14.9% were readmitted within 30  days.

CONCLUSIONS: In this small group of patients, the hybrid procedure was proved to be a safe and efficient way of treatment for patients with concomitant carotid and cardiac diseases. The low rate of perioperative complications and good midterm results are encouraging. PMID: 32247782 [PubMed - as supplied by publisher]

CONCLUSIONS: A similar risk for periprocedural MI between CEA and CAS in NRCSs suggested that concerns about periprocedural MI accompanied by CEA might not matter in real-world practice when preoperative evaluation and management are working. Maybe the benefits of CAS over MT have been overestimated considering advances in medical therapy within10-year gap between CEA-versus-MT and CEA-versus-CAS studies.

LH Abstract BACKGROUND: Carotid artery stenting is an alternative to carotid endarterectomy for the treatment of atherosclerotic carotid artery stenosis. This review updates a previous version first published in 1997 and subsequently updated in 2004, 2007, and 2012. OBJECTIVES: To assess the benefits and risks of stenting compared with endarterectomy in people with symptomatic or asymptomatic carotid stenosis. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (last searched August 2018) and the following databases: CENTRAL, MEDLINE, Embase, and Science Citation Index to August 2018. ...

This study investigates the prognostic significance of pre-operative symptom status and type of symptom in outcomes after carotid endarterectomy (CEA). METHODS: This review was conducted and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analysis (PRISMA) to identify studies reporting peri-operative outcomes of CEA in symptomatic and asymptomatic patients. The last search was conducted in August 2019 and a methodological assessment was performed using the Newcastle Ottawa Scale. A meta-analysis of outcome data using the odds ratio (OR) as the summary statistic was conducted, ...
