Insights

High plasma homocysteine levels are linked to increased coronary artery disease (CAD) risk in the Iranian population. This study highlights homocysteine as a significant biomarker for CAD in this demographic.

Area of Science:

  • Cardiovascular Medicine
  • Biomarkers Research
  • Epidemiology

Background:

  • Growing recognition of novel biomarkers, such as homocysteine, in assessing coronary artery disease (CAD) risk.
  • Observed geographical variations in plasma homocysteine concentrations necessitate population-specific studies.
  • Paucity of research in Iran evaluating hyperhomocysteinemia as a CAD risk factor.

Purpose of the Study:

  • To investigate the association between plasma total homocysteine (tHcy) concentration and CAD risk within the Iranian population.
  • To address the gap in understanding homocysteine's role in cardiovascular health in Iran.

Main Methods:

  • A case-control study design was employed.
  • Forty-five patients with angiographically proven CAD were compared with 45 age- and gender-matched controls without CAD.
  • Exclusion criteria included conventional CAD risk factors (diabetes, hypertension, etc.); plasma tHcy was measured via immunoturbidimetry.

Main Results:

  • Patients with CAD exhibited significantly higher mean plasma tHcy levels compared to the control group (17.1±5.3 vs. 14.2±3.8, P=0.004).
  • The difference in tHcy levels between the groups was statistically significant.

Conclusions:

  • Elevated plasma homocysteine concentration is associated with an increased risk of CAD in the Iranian population.
  • Plasma homocysteine emerges as a relevant biomarker for CAD risk assessment in this demographic.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

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...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
