Obstructive disease of the epicardial coronary arteries was recognized as the cause of
angina pectoris> 2 centuries ago, and sudden thrombotic occlusion of an epicardial …

Early mechanical reperfusion of the epicardial coronary artery by primary percutaneous
coronary intervention (PCI) is the guideline-recommended treatment for ST-elevation …

Background—Most methods for assessing microvascular function are not readily available
in the cardiac catheterization laboratory. The aim of this study is to determine whether the …

Traditionally, invasive coronary physiological assessment has focused on the epicardial
coronary artery. More recently, appreciation of the importance of the coronary …

Objectives: We investigated the reliability of fractional flow reserve (FFR) of nonculprit
coronary stenoses during percutaneous coronary intervention (PCI) in acute myocardial …

Background—A simple, reproducible invasive method for assessing the coronary
microcirculation is lacking. A novel index of microcirculatory resistance (IMR) has been …

A coronary angiography-derived index of microvascular resistance (caIMR) is proposed for
physiological assessment of microvasular diseases in coronary circulation. The aim of the …

Background—The principle of continuous thermodilution can be used to calculate absolute
coronary blood flow and microvascular resistance (R). The aim of the study is to explore the …

Objectives: The objective of this study is to evaluate the predictive value of the index of
microcirculatory resistance (IMR) in patients undergoing primary percutaneous coronary …

The coronary microcirculation plays a pivotal role in the regulation of coronary blood flow
and cardiac metabolism. It can adapt to acute and chronic pathologic conditions such as …
