Interventional cardiology news to note
Adherence to medical therapy worsened over time following percutaneous coronary intervention (PCI), according to data from the Veteran Affairs. Five years after discharge, adherence rates had dropped roughly 15 percentage points for statins, β-blockers, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and by almost 70 points for P2Y12 inhibitors.

Mortality rates 1 year after PCI for ST-segment elevation MI did not hinge on whether patients were admitted on- or off-hours at one Paris hospital, a study showed in JACC: Cardiovascular Interventions.
Drug-coated balloon (DCB) treatment was found to be non-inferior to stenting for non-ST-segment elevation MI treatment, with target lesion failure rates of 3.8% and 6.6%, respectively, in a small randomized trial. Major adverse cardiovascular events also numerically favored the balloons (6.7% vs 14.2%, P=0.11), investigators reported in EuroIntervention.
A double rather than triple antithrombotic regimen conferred less bleeding risk for atrial fibrillation patients who had acute coronary syndrome and/or PCI, a meta-analysis indicated. The benefit came with a significant uptick in stent thrombosis, however. (European Heart Journal)
For stroke patients presenting 6-24 hours after symptom onset, perfusion-based and collateral-based triage resulted in moderate agreement on endovascular thrombectomy and no difference in odds of good outcome among those who did undergo the procedure. (Stroke)
The number of suspected stroke patients getting scanned through the RAPID stroke-imaging platform more than doubled from 2017 to 2019 -- more than tripling at primary stroke centers in particular, according to data from iSchemaView.
A novel ultrasound-controlled paclitaxel coating for DCBs improved the release of the drug in pre-clinical experiments. (Catheterization & Cardiovascular Interventions)
