概括
患有先天性心脏病 (CHD) 的患者具有独特的感染性内心炎 (IE) 形状,并且比没有心脏病的患者有更好的长期存活率. 大多数患有IE的儿童都有潜在的心脏病,这凸显了针对性预防的必要性.
科学领域:
- 心脏病学 心脏病学
- 传染性疾病 传染性疾病
- 公共卫生 公共卫生
背景情况:
- 原发性心脏病 (CHD) 患者是感染性内心炎 (IE) 的高风险组.
- 在包括儿童在内的心血管疾病患者中比较IE的全国数据有限.
- 了解这些差异对于定制的预防和治疗至关重要.
研究的目的:
- 为了比较患有心脏病和没有心脏病的患者的IE特征和结果.
- 分析1977年至2021年丹麦人口中IE的全国数据.
- 为了确定群体之间的人口统计,并发病和死亡率的具体差异.
主要方法:
- 利用丹麦全国性的登记册来识别所有IE病例 (1977-2021年).
- 根据心脏病的存在来分层患者,无论复杂程度如何.
- 比较入院前和入院后的特征,死亡率 (入院,1年,10年) 和IE复发率.
主要成果:
- 确定了14040名IE患者,895人 (6.4%) 患有心脏病.
- 心脏病患者的年龄较小 (中位数为38.8岁与70.7岁),并发病率较低,心脏手术的发生率更高.
- 在18岁以下的IE患者中,有76%患有心脏病;在心脏病组中,住院 (5.7%vs17.0%) 和1年死亡率 (9.9%vs31.8%) 较低.
结论:
- 冠心病患者的传染性内心炎呈现不同,并且具有更好的长期结果.
- 大多数儿科IE病例与潜在的心脏病有关.
- 这些发现强调了承认CHD作为IE流行病学和预后的重要因素的重要性.

Pathophysiology of Heart Failure
1.5K
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...

Immunodeficiency Diseases
926
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Heart Valves
4.4K
The human heart is a complex organ with an intricate system of valves that regulate blood flow. There are two main types of valves: atrioventricular (AV) valves and semilunar valves.
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...

Imaging Studies for Cardiovascular System III: X-Ray
160
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...

Imbalances in Cardiac Output
1.4K
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...

Ischemic Heart Disease: Overview
1.2K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...
