n engl j med 372;1 nejm.org january 1, 2015 94 difference. The observed loss of FEV1 was neither a time-dependent nor a dose-dependent effect in the withdrawal group, as compared with the maintenance group. A difference of 38 ml between groups became apparent only after the final step of inhaled glucocorticoid withdrawal and did not change to a meaningful extent thereafter. Singanayagam et al. ...

[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...

Impact of Right Atrial Pressure on Fractional Flow Reserve Measurements: Comparison of Fractional Flow Reserve and Myocardial Fractional Flow Reserve in 1,600 Coronary Stenoses.

OBJECTIVES This study sought to assess the impact of a wide range of mean right atrial pressure (Pra) on fractional flow reserve (FFR) measurements. BACKGROUND FFR invasively assesses the ischemic potential of coronary stenoses. FFR is calculated as the ratio of mean distal coronary pressure (Pd) to mean aortic pressure (Pa) during maximal hyperemia. The Pra is considered to have little impac...

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...
