Fractional flow reserve in patients with prior myocardial infarction.

BACKGROUND Fractional flow reserve (FFR), an index of coronary stenosis severity, can be calculated from the ratio of hyperemic distal to proximal coronary pressure. An FFR value of 0.75 can distinguish patients with normal and abnormal noninvasive stress testing in case of normal left ventricular function. The present study aimed at investigating the value of FFR in patients with a prior myoca...

The Relationship between Microcirculatory Resistance and Fractional Flow Reserve in Patients with Acute Myocardial Infarction

BACKGROUND AND OBJECTIVES It was demonstrated that the fractional flow reserve (FFR) with partial balloon obstruction may have implications for assessing viable myocardium. In a different way, the index of microcirculatory resistance (IMR) was introduced as a useful indicator for assessing microvascular function. We evaluated the relationship between the FFR0.8 and the IMR. SUBJECTS AND METHO...

Fractional flow reserve-guided management in stable coronary disease and acute myocardial infarction: recent developments

Coronary artery disease (CAD) is a leading global cause of morbidity and mortality, and improvements in the diagnosis and treatment of CAD can reduce the health and economic burden of this condition. Fractional flow reserve (FFR) is an evidence-based diagnostic test of the physiological significance of a coronary artery stenosis. Fractional flow reserve is a pressure-derived index of the maxima...

Fractional Flow Reserve in Acute Myocardial Infarction: A Guide for Non-Culprit Lesions?

In patients presenting with ST-segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD), the optimal therapy for non-culprit lesions is still a matter of debate. While guidelines discourage a concomitant treatment of infarct- and non-infarct-related arteries, recent studies document advantages of a complete (preventive) revascularization during primary percutaneous coronar...

[Myocardial bridging and fractional flow reserve].

Rev Esp Cardiol. 2005;58(9):1117 1117 A 69-year-old patient with a history of hypertension was admitted to the hospital for an acute coronary syndrome. Coronary arteriography showed a myocardial bridge at the mid-distal third of the left anterior descending artery with marked systolic compression. The fractional flow reserve (FFR) following intravenous infusion of adenosine (140 μg/kg) was 0.68...
