According to a recent study published in Circ. Cardiovasc Interv, after a scheduled angioplasty, the rate of arrhythmia requiring some kind of treatment is very low, low enough to deem unnecessary the routine monitoring of all patients. The standard policy at many institutions is continuous cardiac monitoring for several hours after undergoing coronary angioplasty, with…
Reliability of FFR in Patients with Diabetes: Are Other Parameters Necessary?
Diabetes does not seem to alter the results of a fractional flow reserve (FFR) measurement in a given lesion. Recently, expert opinions and small studies had questioned the reliability of FFR in this specific patient subgroup. This new observational study soon to be published in JAMA vanquishes all doubts and confirms the efficacy of this…
FFR in the Time of ISCHEMIA
The results of this great multicenter “real-life” registry are similar to those of randomized clinical trials that studied fractional flow reserve (FFR). Lesion deferral based on FFR is a very safe strategy, even for lesions located in the proximal anterior descending artery. Randomized controlled studies FAME and DEFER convincingly showed the safety of lesion revascularization…
Chronic Inflammation, Coronary Artery Disease and Cancer: Same Coin, Different Sides
Low grade inflammation shown by elevated plasma concentrations of high-sensitive C-reactive protein are a risk factor for coronary artery disease (CAD) patients. There is also evidence to support low grade inflammation could be related to higher risk of cancer. This prospective study evaluated the relation between low grade systemic inflammation and the risk of cancer in…
Secondary Prevention: A Responsibility We Should Not Delegate
After coronary angioplasty, the use of drugs whose efficacy for the reduction of major events has been proven declines over time, which is associated with worse patient prognosis. Sometimes, without meaning to, we convey to patients the idea that, once the stent has been implanted, the artery is “cured” or that the only potential future…
AHA 2019 | ISCHEMIA-CKD: Chronic Kidney Disease and Stable Coronary Disease
Among patients in the main ISCHEMIA trial, those with chronic kidney disease are a particularly high-risk subgroup. However, an invasive strategy with coronary angiography and revascularization did not improve the rate of events, similarly to what happened in the general population for the aforementioned trial. The rate of death or acute myocardial infarction was 36.4%…
Microvascular Angina Could Have Risk Gradients
This study recently published in JACC paves the way to identifying higher risk patients among those with no epicardial coronary artery disease (CAD) that present angina symptoms. Evidence of coronary spasm and increased microcirculation resistance in patients with angina (but with no epicardial obstructive CAD) is associated with increased risk of adverse cardiac events. AT…
AHA 2019 | ISCHEMIA: The Invasive Approach (PCI or Surgery) Results Similar to Optimal Medical Treatment
After a several year follow up, the International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) has shown that an invasive approach in addition to optimal medical treatment (OMT) does not offer benefits when it comes to preventing major cardiovascular events compared against optimal medical treatment alone in stable patients with moderate…
The Road Towards a “More Perfect” Angioplasty Is Already Being Traveled
The aim of revascularization, whether through angioplasty or surgery, is to restore adequate flow to the myocardium; that much is obvious. However, after millions of “successful” procedures with the best technology applied to drug-eluting stents and optimal medical treatment, we still have a high ratio of patients who experience new events. Could an optimal angiographical…
Should Post-PCI Biomarkers Elevation Be of Concern?
Elevated markers after PCI in stable patients treated with the latest generation stents continues to happen. However, only the association between biomarker elevation with creatine kinase-myocardial band (CK-MB) should be of concern, sin it was associated with mortality at one year. Post procedural cardiac troponin (cTn) elevation was not associated to future events, according to…
iFR or FFR Measurements by Sex: Is Either One More Adequate?
According to the post hoc analysis of the DEFINE-FLAIR, patient sex seems to affect instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) guided revascularization outcomes. Even though this is not specified in the study protocols, it might affect the gold standard for functional lesion assessment. However, clinical outcomes are similar with both strategies. Therefore,…
