Insights

Aortic valve calcification (AVC) progresses in many older adults. While common risk factors aren't linked, higher TGF-β1 levels are associated with AVC progression.

Area of Science:

  • Cardiology
  • Gerontology
  • Biomarker Research

Background:

  • Aortic valve calcification (AVC) is a common valvular abnormality leading to stenosis.
  • Progression of AVC and its associated factors are not well understood.
  • This study investigates factors influencing AVC progression in older adults.

Purpose of the Study:

  • To identify clinical factors and serum biomarkers associated with aortic valve calcification progression.
  • To analyze AVC progression in a population-based cohort of elderly individuals.

Main Methods:

  • Utilized data from the Cardiovascular Abnormalities and Brain Lesion (CABL) and Subclinical Atrial Fibrillation And Risk of Ischemic Stroke (SAFARIS) studies.
  • Assessed AVC severity using a 0-3 grading scale on echocardiography at baseline and follow-up.
  • Measured serum biomarkers, including transforming growth factor beta 1 (TGF-β1), at follow-up.

Main Results:

  • 373 participants (mean age 68.1 years) were analyzed; 37% showed AVC progression.
  • Anti-hypertensive medication use was the sole clinical predictor of any AVC progression.
  • Transforming growth factor beta 1 (TGF-β1) was significantly associated with both all and moderate-severe AVC progression.

Conclusions:

  • A notable proportion of elderly individuals with AVC experience disease progression.
  • Individual vascular risk factors were not significantly associated with AVC progression, suggesting a potential combined effect.
  • Elevated TGF-β1 levels are linked to AVC progression in this cohort.

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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...

Aortic Regurgitation III: Medical Management

Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...
