Right ventricular infarction, often linked to inferior heart attacks, ranges from mild dysfunction to shock. Early diagnosis and management are key for patient survival and recovery.

Area of Science:

  • Cardiology
  • Cardiovascular Medicine

Background:

  • Right ventricular infarction (RVI) occurs in up to 50% of inferior myocardial infarctions.
  • RVI presents a spectrum of severity, from asymptomatic dysfunction to cardiogenic shock.
  • It significantly increases morbidity and mortality in patients with inferior myocardial infarction.

Purpose of the Study:

  • To outline the clinical spectrum, diagnostic criteria, and management strategies for right ventricular infarction.
  • To emphasize the importance of early recognition and intervention for improved outcomes.

Main Methods:

  • Clinical suspicion based on symptoms and physical examination.
  • Electrocardiogram (ECG) with right precordial leads.
  • Hemodynamic assessment of right-sided filling pressures relative to left-sided pressures.

Main Results:

  • RVI diagnosis requires high clinical suspicion and specific ECG findings.
  • Elevated right-sided filling pressures disproportionate to left-sided pressures are indicative.
  • Management focuses on preload, afterload, synchrony, and inotropic support.

Conclusions:

  • Prompt diagnosis and management, including early reperfusion, are crucial for RVI patients.
  • Survivors typically experience restoration of right ventricular function and hemodynamic stability.
  • RVI identifies a high-risk subgroup requiring specialized care within inferior myocardial infarction cases.
