Insights
This study analyzed 215 coronary heart disease (CHD) patients, finding gender differences in coronary artery branches and a link between age and intima-media thickness. Atherosclerotic cardiovascular disease (ASCVD) history impacts lesion severity, and lesion location correlates with complications.
Area of Science:
- Cardiology
- Vascular Biology
- Medical Imaging
Background:
- Coronary heart disease (CHD) is a leading cause of mortality worldwide.
- Understanding the anatomical and demographic factors influencing CHD is crucial for effective prevention and treatment.
- Intima-media thickness (IMT) and coronary vessel lesion characteristics are key indicators of cardiovascular risk.
Purpose of the Study:
- To investigate the relationship between demographic factors (gender, age), medical history (ASCVD), and coronary artery anatomy in CHD patients.
- To explore the correlation between coronary artery lesions, intima-media thickness, and the occurrence of complications.
- To assess the predictive value of carotid IMT for left ventricular function in CHD patients.
Main Methods:
- Statistical analysis (SPSS) of data from 215 CHD patients.
- Examination of coronary artery branches, including the obtuse marginal branch, diagonal branch, and RCA.
- Measurement of intima-media thickness (IMT) in carotid arteries and correlation with clinical parameters.
Main Results:
- Significant gender-based differences were observed in specific coronary artery branches (obtuse marginal, diagonal) and MS PV representation.
- Patients with left circumflex branch occlusion were predominantly male and younger.
- Age positively correlated with both left and right IMT, indicating increased thickness with age.
- CHD type showed significance in obtuse marginal, RCA, and LAD branches.
- Non-ST-segment elevation angina with acute occlusion most commonly involved the left circumflex artery.
- Carotid IMT predicted left ventricular function changes, but no direct correlation between left and right carotid IMT was found.
- Patients with a history of ASCVD had a higher number of coronary vessel lesions.
- Complication occurrence was significantly related to the distance of lesions in the left circumflex and LAD branches.
- VTE scores positively correlated with lesion location and number in several coronary arteries.
Conclusions:
- Demographic and clinical factors significantly influence coronary artery anatomy and lesion characteristics in CHD patients.
- Intima-media thickness is associated with age and can predict ventricular function, highlighting its role in CHD.
- The location and number of coronary lesions are critical indicators for predicting complications and VTE risk.
Abstract:
A total of 215 patients with coronary heart disease (CHD) were analyzed with SPSS. Samples of different genders showed significance in the obtuse marginal branch of the left circumflex branch × 1, the diagonal branch D1 × 1, and the ms PV representation. Patients with left circumflex branch occlusion are more male and tend to be younger. Age displayed a positive correlation with left intima-media thickness (IMT) and right IMT. This indicated that as age increases, the values of left IMT and right IMT increase. Samples of different CHD types showed significance in the obtuse marginal branch of the left circumflex branch × 1, the middle part of RCA × 1, and the middle part of the left anterior descending branch × 1.5. For non-ST-segment elevation angina pectoris with acute total vascular occlusion, the left circumflex artery is the most common, followed by the right coronary artery and anterior descending branch. Ultrasound of carotid IMT in patients with CHD can predict changes in left ventricular function, but no specific correlation between left and right common carotid IMT was found. Samples with or without the medical history of ASCVD showed significance in the branch number of coronary vessel lesions. The value of the branch number of coronary vessel lesions in patients with atherosclerotic cardiovascular disease (ASCVD) was higher than in those without ASCVD. The occurrence of complication is significantly relative with the distance of left circumflex branch × 1, the middle segment of left anterior descending branch × 1.5, and the distance of left anterior descending branch × 1. For patients without complications, the values in the distal left circumflex branch × 1, the middle left anterior descending branch × 1.5, and the distal left anterior descending branch × 1 were higher than those for patients with complications. The VTE scores showed a positive correlation with the proximal part of RCA × 1, the branch number of coronary vessel lesions, the posterior descending branch of left circumflex branch × 1, the distal part of left circumflex branch × 1, and the middle part of left anterior descending branch × 1.5.
