Insights

Severe tricuspid regurgitation is linked to increased mortality in advanced heart failure patients. This study identified factors associated with severe tricuspid regurgitation, highlighting its prognostic significance.

Area of Science:

  • Cardiology
  • Cardiovascular Medicine
  • Echocardiography

Background:

  • Tricuspid regurgitation (TR) is common in heart failure (HF).
  • The prognostic impact of TR in advanced HF requires further elucidation.
  • Understanding TR's role is crucial for managing complex HF patients.

Purpose of the Study:

  • To assess the role of tricuspid regurgitation in advanced heart failure.
  • To identify clinical factors associated with severe TR.
  • To evaluate the association between TR severity and mortality.

Main Methods:

  • Observational, multicenter study (HELP-HF registry) of advanced HF patients.
  • Stratification based on TR severity: none/mild, moderate, severe.
  • Analysis of factors associated with severe TR and its impact on all-cause mortality.

Main Results:

  • 1085 patients included; 18.8% had severe TR.
  • Atrial fibrillation, prior valve surgery, furosemide dose, LVEF, mitral regurgitation, and pulmonary hypertension were linked to severe TR.
  • 1-year mortality was 37.1% for severe TR vs. 21.4% for none/mild TR (P < 0.001).
  • Severe TR independently predicted higher all-cause mortality (aHR 1.38, P=0.042).

Conclusions:

  • Clinical and echocardiographic factors predict severe TR in advanced HF.
  • Severe TR is an independent predictor of mortality in this population.
  • Management strategies for advanced HF should consider TR severity.

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
