Insights

Untreated hypertension is the primary driver of heart failure in Nigeria, impacting 61.5% of patients. This study highlights the need for better hypertension management to reduce heart failure prevalence in sub-Saharan Africa.

Area of Science:

  • Cardiology
  • Public Health
  • Echocardiography

Background:

  • Heart failure is a significant health concern in sub-Saharan Africa, yet comprehensive echocardiographic data remains scarce.
  • Understanding the specific etiological factors and clinical presentations of heart failure in this region is crucial for effective management.

Purpose of the Study:

  • To analyze the clinical and echocardiographic characteristics of heart failure patients in a Nigerian tertiary institution.
  • To identify the leading causes and types of heart failure within this specific population.

Main Methods:

  • A study of 340 consecutive heart failure patients, diagnosed per European Society of Cardiology guidelines.
  • Two-dimensional transthoracic echocardiography was performed on all participants.

Main Results:

  • The average age of patients was 50.60 years, with a near-equal gender distribution (50.9% male, 49.1% female).
  • Hypertension was the most frequent cause of heart failure (61.5%).
  • Systolic heart failure (75.5%) was more prevalent than heart failure with preserved ejection fraction (23.5%).

Conclusions:

  • Untreated hypertension is the predominant cause of heart failure in Abuja, Nigeria, mirroring trends in broader sub-Saharan Africa.
  • Coronary artery disease is an infrequent contributor to heart failure in this population, underscoring the impact of hypertension.

Pathophysiology of Heart Failure01:17

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...

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...

Imaging Studies for Cardiovascular System I:Echocardiography

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, evaluates...

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...

Imaging Studies for Cardiovascular System II:Types of Echocardiography

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 diagnosing...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...
