概括
连续运动心声学 (EEC) 是安全有效的管理无症状的严重大动脉狭窄症. 年度EEC有助于确定主动脉替换 (AVR) 的最佳时间,改善患者的治疗结果.
科学领域:
- 心脏病学 心脏病学
- 心声回声图 (Echocardiography) 是一种心声回声图.
- 膜心脏疾病 膜心脏疾病
背景情况:
- 在无症状严重的大动脉狭窄症中,连续运动心声学 (EEC) 的预后价值仍然不清楚.
- 使用年度EEC监测无症状严重大动脉狭窄症患者的监测是指导大动脉置换 (AVR) 决策的潜在策略.
研究的目的:
- 评估连续EEC在治疗无症状严重大动脉狭窄症中的安全性和实用性.
- 确定每年EEC是否可以有效指导AVR转诊或持续后续行动.
主要方法:
- 一组196名患有无症状严重大动脉狭窄和正常查EEC的患者接受了连续的年度EEC和休息的胸前回声心脏成像.
- 转诊为AVR是基于症状,静止心电回声学发现 (例如,左心室功能障碍,峰值速度≥5m/s) 或EEC发现 (例如,炼症状,心律失常,血压变化).
主要成果:
- 在任何EEC程序中都没有出现严重的并发症.
- 连续的EEC在23.5%-50%的病例中产生了AVR转诊的积极结果,而静止心声回声仪则产生了0%-22%的结果.
- 大动脉置换延迟了平均2.93年,没有报告心脏相关或突然死亡.
结论:
- 连续EEC是安全的,并且在治疗无症状严重大动脉狭窄症时具有预后价值.
- 年度EEC可以有效地指导该患者群体的AVR及时决策.

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Imaging Studies for Cardiovascular System I:Echocardiography
294
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,...

Mitral Valve Prolapse II: Assessment and Management
1
IntroductionA range of clinical features characterizes Mitral Valve Prolapse (MVP), but it is important to note that many individuals with MVP are asymptomatic and may remain so throughout their lives. For those who do exhibit symptoms, the following are the key clinical features:Palpitations: This is a common symptom where individuals feel an irregular or rapid heartbeat. Palpitations in MVP are often due to arrhythmias such as premature ventricular contractions or supraventricular...
