- 统计分析包括描述性统计,t测试和单向ANOVA,以比较主导群体之间的结果.
主要成果:
- 最常见的是右冠状动脉主导 (85.7%),其次是左冠状动脉 (11.6%) 和共主导 (2.7%).
- 与左侧或右侧主导动脉相比,与左侧或右侧主导动脉相比,右侧冠状动脉 (RCA) 问题 (22.2%) 和阻塞性RCA病变 (14.8%) 的发生率显著更高 (分别为p=0.001和p=0.018).
- 冠状动脉主导并没有显著影响左主冠状动脉,左前下降,左环或拉姆斯动脉的狭窄.
结论:
- 冠状动脉主导,特别是共同主导,与右冠状动脉疾病的严重程度增加有关.
- 冠状动脉CTA对于识别阻塞性CAD,特别是RCA有价值,并可能有助于对具有特定主导模式的患者进行风险评估.
- 在正常或不显著的CAD患者中,CTA可能不会提供超出狭窄性评估的额外风险信息.

4.2K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

01:20Imaging Studies for Cardiovascular System III: X-Ray
116
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

01:21Coronary Circulation
1.8K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

273
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...
