For many patients, the first symptom of heart disease is acute MI, or even sudden death. Changes in lifestyle and optimal medical treatment (OMT) are vital to the prevention of serious events, but we cannot help wondering whether preventive stenting might do it. Intravascular ultrasound (IVUS), optical coherence tomography (OCT), NIRS near-infrared spectroscopy (NIRS) and computed...
Suboptimal fractional flow reserve (FFR) results after stenting only have a moderate impact on clinical hard points but might predict a much higher risk of reintervention. FFR has shown a huge impact on the decision-making process when it comes to revascularizing (or not) a lesion. Its impact after angioplasty has not been fully studied, particularly...
The FREEDOM has clearly established the benefit of myocardial revascularization surgery (CABG) over percutaneous coronary intervention (PCI) in diabetic patients with multivessel disease. Coronary physiology as guideline for revascularization works best precisely in this kind of patients and its impact has never been studied in diabetics. This study, published in Circ Cardiovasc Interv, assessed the...
Global fractional flow reserve (FFR) results from adding up FFR values of the three major coronary arteries. This figure represents the physiological atherosclerosis burden and can predict events at long term in patients without stenosis leading to ischemia. This recent study published in JAHA looked at major cardiovascular events (death, infarction and revascularization) at 5...
When operators decide to proceed with PCI despite a negative FFR (fairly frequent in the daily practice) outcomes at 5 years are far worse. This information comes from a large Canadian register presented at AHA 2020 Scientific Sessions, simultaneously published in JAMA. PCI to a non-ischemic lesion results in increased events risk at long term,...
Invasive functional measurement of intermediate lesions has become the gold standard to define revascularization. Due to its favorable long-term prognostic value, fractional flow reserve (FFR) is the reference used to compare all others. Recently, new nonhyperemic indexes, measured in a specific diastolic period, have emerged. Among them, the one with the most accumulated evidence is...
The TARGET FFR and DEFINE-FLOW studies were presented at TCT 2020 which have offer a deeper perspective on the value of FFR, not only before but also after PCI. TARGET FFR The TARGET FFR included 260 patients randomized after angiographically successful PCI to an FFR guided optimization vs. blinded FFR assessment strategies. In the guided...
Optical coherence tomography (OCT) has proven useful in diabetic patients, even those with negative FFR. These findings make us rethink the ischemia and functional revascularization paradigm vs. the anatomical findings of vulnerable plaque. Diabetic patients with lesions that might be deferred base don FFR might benefit from OCT to find in these plaques certain risk...
Age may impact results when making an angioplasty choice based on fractional flow reserve (FFR) vs. instantaneous wave-free ratio (iFR). After 2 years of follow-up, patients whose treatment of intermediate lesions was deferred based on functional testing had similar outcomes regardless of whether this decision was informed by FFR or iFR. However, iFR performance was constant,...
Magnetic resonance (MR) and fractional flow reserve (FFR) correlate moderately as regards the assessment of non-culprit lesions in patients admitted with acute myocardial infarction who underwent primary angioplasty. For a similar degree of diagnostic accuracy, we would require a visual, semiquantitative, or fully quantitative comprehensive assessment of lesions. This work, soon to be published in...
