Insights

Black Africans with rheumatoid arthritis (RA) do not show reduced atherosclerotic cardiovascular disease (CVD) risk. Cardiovascular disease risk assessment in RA patients should not depend on ethnic origin.

Area of Science:

  • Rheumatology and Cardiovascular Medicine
  • Epidemiology of Chronic Diseases

Background:

  • Black Africans are perceived to have a lower risk of atherosclerotic cardiovascular disease (CVD).
  • This study examines whether this protective effect extends to Black Africans with rheumatoid arthritis (RA).

Purpose of the Study:

  • To investigate atherosclerotic cardiovascular disease (CVD) risk factor profiles and arterial stiffness in Black Africans with rheumatoid arthritis (RA).
  • To compare CVD risk between Black Africans and other ethnic groups with RA.

Main Methods:

  • Multivariable regression models were used to analyze CVD risk factors and arterial stiffness.
  • Risk factors included conventional (hypertension, dyslipidemia, smoking, diabetes, metabolic syndrome) and nonconventional (rheumatoid factor, inflammation markers) measures.
  • Arterial stiffness was assessed using brachial pulse pressure.

Main Results:

  • Black Africans with RA had higher rates of hypertension and diabetes but lower smoking rates.
  • Despite differences in individual risk factors, overall CVD risk scores and metabolic syndrome prevalence were similar between ethnic groups.
  • Black ethnicity was not independently associated with inflammation markers or arterial stiffness.

Conclusions:

  • Black patients with RA do not exhibit reduced overall atherosclerotic CVD risk or arterial stiffness compared to other ethnic groups.
  • Cardiovascular disease risk management in RA should be individualized, irrespective of ethnicity or epidemiological transition stage.

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
