心脏病学心脏病学
遗传学遗传学是一个
放射学放射学是一门学科.

背景情况:

血管埃勒斯-丹洛斯综合征 (vEDS) 是一种严重的遗传性疾病,影响连接组织,主要是III型原.
它的特点是动脉剖析,器官破裂和高死亡率.
了解心脏参与对于管理vEDS并发症至关重要.

研究的目的:

评估心脏MRI.使用心脏MRI.使用vEDS的成年人心室大小和功能.
调查心脏参数和与vEDS相关的并发症 (如剖析,动脉瘤和肺胸部) 之间的关联.

主要方法:

对26名遗传确诊vEDS的成年人和26名匹配的健康对照者的心脏MRI数据进行了回顾性比较.
分析包括心室体积,射出分数 (LVEF,RVEF) 和动脉血管评估.
用多变量逻辑回归对心脏发现与已记录的vEDS并发症的相关性.

主要成果:

与对照组相比,患有vEDS的个体表现出明显较低的左心室和右心室喷射分数 (LVEF,RVEF).
增加的左心室末缩体积 (LVEDVi) 和末缩体积 (LVESVi) 与更高的剖析率和动脉瘤有关.

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

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...

Pathophysiology of Heart Failure

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Imbalances in Cardiac Output

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Assessment of the Cardiovascular System III: Palpation

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
