概括

右心室缩功能障碍 (RVSD) 在尼日利亚非洲人中常见,患有高血压心力衰竭 (HF),并独立预测死亡. 右心室扩张功能障碍 (RVDD) 和肺高血压 (PH) 也会增加死亡风险,但由其他因素解释.

科学领域:

心脏病学心脏病学
心声回声扫描 (Echocardiography) 是一种心声回声扫描.
公共卫生公共卫生

背景情况:

在非洲心力衰竭 (HF) 患者中,右心室功能障碍 (RVD) 和肺高血压 (PH) 的患病率和预后意义仍未得到充分研究.
与其他种族相比,高血压高血压在非洲人群中表现出不同的轨迹.
这项研究侧重于尼日利亚裔非洲人患高血压高血压,以解决这些知识差距.

研究的目的:

确定尼日利亚-非洲人高血压高的RVD和PH的频率.
评估RVD和PH在事故死亡中的独立预后相关性.
调查右心室缩功能障碍 (RVSD),右心室透缩功能障碍 (RVDD) 和PH与死亡率的关联.

主要方法:

对118名尼日利亚裔非洲人的分析,他们患有门诊高血压HF.
通过心声学评估的RVD (三流入,组织多普勒,TAPSE).
通过心声扫描的静脉脉压 (SPAP) 评估PH.
预测因子的多变量逻辑回归;生存分析的卡普兰-梅尔和考克斯回归.

主要成果:

患病率很高:RVSD (56.8%),RVDD (65.3%),PH (56.8%). 这种疾病的发病率很高.
在2.4年内,RVSD,RVDD和PH与死亡风险增加有关.
只有RVSD在相互调整和对左心室功能等调解器进行计算后仍然是死亡的独立预测因素.

结论:

尼日利亚-非洲人中高血压高血压的RVSD,RVDD和PH普遍存在.
RVSD是事故死亡的唯一独立预测因素,强调了其至关重要的预后重要性.
这些发现突出了在这个人群中对RVSD进行有针对性的评估和管理的需要.

关键词:

这是一个RVSDRVSD.这就是TAPSE.TAPSE.心脏衰竭是因为心脏衰竭.肺高血压是一种肺高血压.

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...

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary Hypertension: Classification and Pathogenesis

Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Mitral Regurgitation I: Introduction

Mitral Regurgitation I: Introduction

Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Heart Failure I: Introduction

Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

Heart Failure II: Pathophysiology

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Heart Failure III: Clinical Manifestations

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...
