Insights

Hypertension with left ventricular hypertrophy (LVH) is linked to distinct metabolic changes and gut microbiome alterations. Identifying these gut microbiota biomarkers can aid in managing hypertension and preventing organ damage.

Area of Science:

  • Cardiology
  • Microbiology
  • Metabolomics

Background:

  • Hypertension is a leading cause of cardiovascular disease.
  • Left ventricular hypertrophy (LVH) is a common complication of hypertension, indicating target organ damage.
  • Gut microbiota alterations are increasingly recognized as contributing factors in various diseases, including cardiovascular conditions.

Purpose of the Study:

  • To identify potential diagnostic biomarkers for hypertension with LVH.
  • To characterize the clinical features and gut microbiota profiles associated with hypertension and LVH.
  • To explore the relationship between gut microbiota composition and metabolic abnormalities in hypertensive patients with LVH.

Main Methods:

  • Classification of participants into three groups: hypertrophy (hypertension with LVH), non-hypertrophy (hypertension without LVH), and healthy controls.
  • Recording of clinical parameters including body mass index (BMI), uric acid, triglycerides, homocysteine, estimated glomerular filtration rate, and high-density lipoprotein cholesterol.
  • Analysis of fecal samples for gut microbial diversity, abundance, and distribution at different taxonomic levels (phylum, genus, species).

Main Results:

  • Patients with hypertension and LVH showed elevated BMI, uric acid, triglycerides, homocysteine, and γ-glutamyl transferase, with reduced estimated glomerular filtration rate and high-density lipoprotein cholesterol.
  • A significant reduction in Actinobacteria abundance was observed in the LVH group compared to controls.
  • The genus *Blautia* was enriched, and *Streptococcus equinus* was more abundant in patients with LVH. Gut microbiota markers demonstrated good diagnostic potential for LVH.

Conclusions:

  • Hypertension with LVH is associated with specific metabolic disturbances and altered gut microbiota composition.
  • Gut microbiota alterations, including changes in specific genera and species, may serve as potential biomarkers for hypertension-related target organ damage.
  • These findings suggest novel avenues for the prevention and management of LVH in hypertensive individuals through modulation of the gut microbiome.

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

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...

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...

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,...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Hypertension I: Introduction01:28

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...
