Heart Failure II: Pathophysiology

1.0K
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...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

604
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...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

539
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...

Summary
This summary is machine-generated.

Left atrial (LA) function, assessed via echocardiography, predicts mortality in very elderly individuals. Impaired LA function independently indicates higher 5-year mortality risk, regardless of LA size.

Area of Science:

  • Cardiology
  • Geriatric Medicine
  • Echocardiography

Background:

  • Left atrial (LA) size is linked to mortality in the elderly.
  • The prognostic value of specific LA function indices remains unclear.

Purpose of the Study:

  • To determine if echocardiographic LA function parameters predict 5-year mortality in 85-86 year olds.
  • To assess if these predictions are independent of LA volume.

Main Methods:

  • Echocardiography was performed on 282 community-dwelling individuals aged 85-86.
  • LA volumes, expansion index, and emptying fractions (passive and active) were measured.
  • Survival status was tracked for 5 years.

Main Results:

  • 31% of subjects (87) died within 5 years.
  • Lower LA expansion index and active filling index were associated with significantly lower survival.
  • LA function indices remained significant predictors of survival even after accounting for LA volume.

Conclusions:

  • Impaired LA function is associated with increased 5-year mortality in very elderly individuals.
  • These findings are independent of LA size, highlighting LA function's prognostic importance.
