Insights
Carotid artery stenting (CAS) can lead to hemodynamic depression (HD). Using temporary cardiac pacemakers during CAS may help reduce HD and major adverse perioperative cardiovascular events (MACCE).
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Carotid artery stenting (CAS) is a common procedure for treating carotid artery stenosis.
- Hemodynamic depression (HD) is a potential complication following CAS.
- Understanding the factors contributing to HD is crucial for improving patient outcomes.
Purpose of the Study:
- To investigate the pathogenesis and related factors of hemodynamic depression (HD) after carotid artery stenting (CAS).
- To evaluate the effectiveness of temporary cardiac pacemakers in managing HD and reducing perioperative complications.
Main Methods:
- A retrospective study of 433 patients undergoing CAS between January 2013 and June 2016.
- Establishment of diagnostic criteria for HD in CAS patients.
- Analysis of cerebral angiography, carotid plaque morphology, and the use of temporary cardiac pacemakers.
- Classification of patients into HD and non-HD groups for comparative analysis.
Main Results:
- 59.80% of patients (241/433) developed HD after CAS.
- No significant difference in HD prevalence was observed between groups, except for a higher incidence in patients with diabetes.
- Bilateral CAS was associated with a significantly higher incidence of HD (p<0.05).
- The HD group experienced a higher number of major adverse perioperative cardiovascular events (MACCE) (31 vs. 2).
Conclusions:
- Temporary cardiac pacing may be an effective strategy to mitigate HD after CAS.
- Utilizing temporary cardiac pacemakers could potentially reduce perioperative MACCE in patients undergoing CAS.
Objective:
To investigate the pathogenesis and related factors of carotid artery stenting (CAS) related to hemodynamic depression (HD).
Patients And Methods:
433 CAS patients were admitted to our hospital and were selected from Jan 2013 to Jun 2016. We set up the HD diagnostic criteria for CAS and observed the whole morphology of vessels to classify carotid atherosclerotic plaques. We analyzed cerebral angiography and placed temporary cardiac pacemaker via femoral vein in order to prepare carotid artery stenting. We determined the general situation of HD after CAS according to the results.
Results:
38 patients received temporary placement of cardiac temporary pacemakers, and 241 patients (59.80%) developed HD. 403 patients were divided into HD group and non HD group and results suggested there was no significant difference between the two groups except for diabetes (p>0.05). Also, bilateral carotid stenting was performed in 26 patients (6.45%), and the HD group was significantly higher than that in non HD group (p<0.05). HD group had 31 MACCE cases, and non HD group had 2 MACCE cases. There was no occurrence of adverse cardiovascular events in this study.
Conclusions:
Cardiac temporary pacemaker may be one of the effective approaches to improve HD after CAS and reduce perioperative MACCE.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Electrolytes: van't Hoff Factor
The colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one...
