Research Progress and Clinical Value of Subendocardial Viability Ratio

Area of Science:

• Cardiology
• Physiology

Background:

• Cardiovascular disease is a leading global cause of death.
• Ischemic heart disease, driven by plaque or microvascular dysfunction, impairs myocardial perfusion.
• Acute myocardial infarction can result from severe coronary blood flow obstruction.

Purpose of the Study:

• To review the applications and clinical significance of the subendocardial viability ratio.
• To highlight recent research progress concerning this myocardial perfusion index.
• To underscore its predictive value for cardiovascular events and mortality.

Main Methods:

• Review of existing literature on the subendocardial viability ratio.
• Analysis of its role in evaluating myocardial perfusion and coronary microcirculation.
• Examination of its association with arterial stiffness and clinical outcomes.

Main Results:

• The subendocardial viability ratio effectively balances myocardial oxygen supply and demand.
• It is a valuable tool for assessing coronary microcirculation function.
• The ratio shows predictive potential for adverse cardiovascular events and mortality across diverse populations.

Conclusions:

• The subendocardial viability ratio is crucial for evaluating myocardial perfusion.
• Its clinical significance extends to various conditions like hypertension, diabetes, and CKD.
• Further research and application of this ratio can improve cardiovascular disease management.
