Insights

Elevated high-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) indicate subclinical cardiac changes in hypertensive patients. These biomarkers are linked to left ventricular remodeling, impaired function, and arterial enlargement.

Area of Science:

  • Cardiology
  • Biomarkers
  • Hypertension Research

Background:

  • High-sensitivity cardiac troponin T (hs-cTnT) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are established markers for cardiac dysfunction.
  • Limited data exist on their association with multidimensional echocardiographic features in hypertensive individuals.

Purpose of the Study:

  • To investigate the relationship between hs-cTnT and NT-proBNP levels and echocardiographic parameters in patients with hypertension.
  • To assess the combined impact of these biomarkers on cardiac structure and function.

Main Methods:

  • A multicenter prospective cohort study included 1803 hypertensive adults who underwent echocardiography.
  • Serum hs-cTnT and NT-proBNP levels were measured and analyzed in association with echocardiographic features using multivariable-adjusted models.

Main Results:

  • Higher hs-cTnT levels correlated with increased left ventricular and atrial remodeling, and higher flow velocity.
  • Elevated NT-proBNP was associated with structural changes, impaired diastolic function, and arterial enlargement.
  • The highest tertiles for both biomarkers showed the most pronounced cardiac abnormalities, including increased interventricular septum thickness and worse diastolic function.

Conclusions:

  • Elevations in hs-cTnT and/or NT-proBNP are associated with subclinical cardiac structural and functional abnormalities in hypertensive patients.
  • These biomarkers may help identify individuals at risk for cardiac complications within the hypertensive population.

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:

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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

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...
