Right ventricular dysfunction after thrombolysis in patients with right ventricular infarction

Area of Science:

• Cardiology
• Echocardiography
• Myocardial Infarction

Background:

• Right ventricular (RV) infarction carries a high risk of mortality and complications.
• Doppler echocardiography aids in diagnosing RV involvement.
• This study aimed to identify echocardiographic features predicting poor prognosis in RV infarction.

Purpose of the Study:

• To evaluate Doppler echocardiography features associated with RV involvement.
• To identify echocardiographic markers of poor prognosis in RV infarction patients.

Main Methods:

• 108 RV infarction patients underwent 2D Doppler echocardiography before and after thrombolysis.
• Echocardiography was performed at multiple time points: pre-thrombolysis, 2-3 hours, 1 day, and 7 days post-thrombolysis.
• Coronary angiography assessed coronary artery perfusion (TIMI grade).

Main Results:

• Patients with improved RV wall motion after thrombolysis showed 78% TIMI grade III perfusion.
• Normalization of septal motion occurred in all reperfused patients.
• Persistent RV dysfunction on echocardiography correlated with increased major complications and mortality.

Conclusions:

• Persistent RV dysfunction after thrombolysis in RV infarction is linked to increased risk of major cardiac complications and death.
• Echocardiography is crucial for risk stratification in RV infarction patients post-thrombolysis.
