Preserving left ventricular function during percutaneous coronary intervention

Area of Science:

• Cardiology
• Cardiovascular Medicine
• Interventional Cardiology

Background:

• The heart failure epidemic is driven by coronary artery disease, improved treatments, and an aging population.
• Coronary interventions, while beneficial, can paradoxically lead to left ventricular systolic dysfunction (LVSD) by causing iatrogenic myocardial damage.
• Preventing or limiting myocardial damage during coronary interventions is crucial for managing heart failure.

Purpose of the Study:

• To discuss strategies for limiting myocardial damage during coronary interventions.
• To highlight the risk of iatrogenic left ventricular systolic dysfunction (LVSD) following coronary procedures.
• To emphasize the need for risk stratification and tailored approaches to minimize LVSD induction.

Main Methods:

• Review of current literature on coronary intervention techniques and their impact on left ventricular function.
• Analysis of strategies aimed at reducing myocardial injury during percutaneous coronary interventions.
• Discussion of risk assessment tools for predicting LVSD post-intervention.

Main Results:

• Coronary interventions carry a risk of inducing left ventricular systolic dysfunction (LVSD).
• Specific procedural techniques and patient factors influence the likelihood of iatrogenic LVSD.
• Proactive risk assessment and management strategies can mitigate the incidence of LVSD.

Conclusions:

• Interventional cardiologists must actively manage the risk of iatrogenic LVSD during coronary interventions.
• Qualifying procedures as high or low risk for LVSD induction is essential.
• Implementing strategies to minimize myocardial damage is the next critical step in preventing heart failure.
