Insights

Shorter telomeres in white blood cells are linked to carotid artery plaques in hypertensive men. This suggests telomere length may predict atherosclerosis risk in individuals with high blood pressure.

Area of Science:

  • Cardiovascular Medicine
  • Genetics
  • Hypertension Research

Background:

  • Shorter telomeres are associated with increased cardiovascular disease mortality and arterial lesions.
  • Hypertension is a significant risk factor for cardiovascular diseases, but susceptibility to atherosclerotic lesions varies among patients.

Purpose of the Study:

  • To investigate the association between white blood cell telomere length and the presence of carotid artery atherosclerotic plaques in hypertensive males.

Main Methods:

  • Analysis of data from 163 treated hypertensive men.
  • Assessment of extracranial carotid plaques using B-mode ultrasound.
  • Measurement of telomere length from DNA extracted from white blood cells.

Main Results:

  • Hypertensive men with carotid artery plaques had significantly shorter telomere lengths (8.17+/-0.07 kb) compared to those without plaques (8.46+/-0.07 kb).
  • Multivariate analysis identified telomere length as a significant predictor of carotid artery plaque presence, independent of age.

Conclusions:

  • In hypertensive males, shorter white blood cell telomere length is associated with a higher likelihood of developing carotid artery atherosclerosis.
  • Telomere length may serve as a biomarker for predicting atherosclerosis risk in the context of hypertension.

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...

Telomeres and Telomerase

In eukaryotic DNA replication, a single-stranded DNA fragment remains at the end of a chromosome after the removal of the final primer. This section of DNA cannot be replicated in the same manner as the rest of the strand because there is no 3’ end to which the newly synthesized DNA can attach. This non-replicated fragment results in gradual loss of the chromosomal DNA during each cell duplication. Additionally, it can induce a DNA damage response by enzymes that recognize single-stranded DNA.

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

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...
Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...

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...
