Aneurysm II: Clinical Manifestations and Diagnostic Studies

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Background:

Aortic dissection (AD) is a rare but dangerous cardiovascular disease with high rates of misdiagnosis.
Early detection of AD is challenging due to complex symptoms.

Purpose of the Study:

To develop a fast and accurate screening model for AD using machine learning.
To utilize routine patient examination data for predictive AD diagnosis.

Main Methods:

Retrospective analysis of 53,213 cardiovascular disease patients, including 802 with AD.
Extracted 42 features from routine data to build prediction models.
Evaluated five ensemble learning models (AdaBoost, XGBoost, SmoteBagging, EasyEnsemble, XGBF), with XGBF proposed for imbalanced data.

Main Results:

The proposed XGBF model achieved 80.5% sensitivity, significantly outperforming other models.
XGBF demonstrated high specificity and short training time.
The XGBF model met application requirements for early AD screening.

Conclusions:

Ensemble learning methods can effectively screen for AD.
The XGBF model shows significant practical value for early aortic dissection screening.
