[Prognostic evaluation of unfavorable coronary atherosclerosis]
Insights
This study optimized patient questioning for detecting severe coronary atherosclerosis. A new evaluation chart aids general practitioners, improving diagnostic accuracy and reducing unnecessary tests for coronary angiography.
Area of Science:
- Cardiology
- Medical Diagnostics
- Clinical Research
Background:
- Coronary atherosclerosis poses significant health risks.
- Accurate detection of severe coronary atherosclerosis is crucial for patient prognosis.
- Current diagnostic methods for coronary atherosclerosis can be resource-intensive.
Purpose of the Study:
- To optimize the evaluation of patient questioning data for detecting prognostically unfavorable coronary atherosclerosis (PUCA).
- To develop a practical tool for general practitioners to assess the a priori probability (APP) of severe coronary atherosclerosis.
- To reduce the need for invasive procedures like coronary angiography (CAG) through improved initial assessment.
Main Methods:
- Detailed patient questioning including pain syndrome analysis.
- Evaluation of a priori probability (APP) of coronary heart disease and functional classification.
- Selective coronary angiography (CAG) to confirm coronary atherosclerosis severity.
- Development of a preliminary evaluation chart for PUCA APP based on questioning data and CAG results.
Main Results:
- A user-friendly chart for preliminary evaluation of PUCA APP was developed for general practitioners.
- The developed chart demonstrated a high rate of reliable diagnostic conclusions (56.5 +/- 4.5%).
- The chart significantly decreases the necessity for loading tests in the selection process for CAG.
Conclusions:
- The optimized evaluation of questioning data provides a reliable method for detecting severe coronary atherosclerosis.
- The developed chart is a valuable tool for general practitioners, enhancing diagnostic efficiency.
- This approach can streamline the patient pathway towards coronary angiography, optimizing resource utilization.
Abstract:
The aim of the study was optimization of the evaluation of questioning data for detection of prognostically unfavorable coronary atherosclerosis (PUCA). The subjects were 124 patients (96 men; 28 women) with chest pain and coronary atherosclerosis risk factors. The patients were questioned in detail; the character of pain syndrome was analyzed; a priori probability (APP) of coronary heart disease was evaluated; a functional class according to Canadian Cardiovascular Society Functional Classification was established. All the patients underwent selective coronaroangiography (CAG). Coronary atherosclerosis was considered to be severe (PUCA) under the following conditions: 1) stenosis of the main trunk of the left coronary artery by at least 70% of the diameter; 2) stenosis of the anterior descending artery in the first segment by at least 95% of the diameter in the presence of stenosis of the other magistral coronary artery by at least 75% of the diameter; 3) stenosis of all the three magistral coronary arteries by at least 75% of the diameter. After the matching of the questioning data with CAG results, a chart of preliminary evaluation of APP of severe coronary atherosclerosis, approachable for general practitioners, was developed. The offered chart of evaluation of PUCA APP is characterized by high rate of reliable diagnostic conclusions (56.5 +/- 4.5%), and allows substantial decrease in the need for loading tests when selection for CAG is performed.
