[Indications for heart transplantation (excluding emergencies)]

Area of Science:

• Cardiology
• Transplantation Medicine
• Medical Ethics

Background:

• Advances in diagnosing chronic cardiac failure have increased the pool of potential transplant candidates.
• A significant shortage of donor hearts necessitates careful consideration of transplantation indications.
• The New York Heart Association (NYHA) classification system is a key tool in assessing heart failure severity.

Purpose of the Study:

• To re-examine and refine the indications for cardiac transplantation in light of improved diagnostics and donor organ scarcity.
• To establish criteria for selecting patients who will most benefit from cardiac transplantation, focusing on prognosis and quality of life.
• To optimize the allocation of scarce donor hearts to patients with the greatest potential for positive outcomes.

Main Methods:

• Review of current diagnostic criteria for chronic cardiac failure.
• Analysis of patient stratification using the NYHA classification.
• Evaluation of prognostic indicators such as VO2 max, arrhythmogenic potential, disease progression, and treatment resistance.

Main Results:

• Cardiac transplantation is a clear indication for NYHA class IV patients to improve quality of life, barring contraindications.
• For less symptomatic patients (NYHA class I-III), indications should be based on prognostic factors like VO2 max and arrhythmogenic potential.
• Disease progression indicators, including resistance to therapy and recurrent decompensation, are crucial for patient selection.

Conclusions:

• Cardiac transplantation indications require a nuanced approach, balancing patient need with organ availability.
• Objective criteria, including physiological parameters and disease trajectory, are essential for equitable donor heart distribution.
• Reevaluation of transplantation indications ensures optimal resource utilization for patients with the highest likelihood of long-term benefit.
