Long-term Variations of FFR and iFR After Transcatheter Aortic Valve Implantation
Original Research | By R Scarsini, M Lunardi, F Ribichini et al.
Long-term variations of fractional flow reserve (FFR) and instantaneous wave-free-ratio (iFR) after transcatheter aortic valve implantation (TAVI) have not been previously assessed. A total of 23 coronary lesions in 14 patients with aortic stenosis (AS) underwent physiology assessment at baseline, immediately after TAVI and at 14(7-29) months of follow-up. The angiographic severity of the lesions did not progress at follow-up (54[45-...

Association of Sustained Blood Pressure Control with Multimorbidity Progression Among Older Adults
Original Research | By CB Bowling, R Sloane, C Pieper et al.
BACKGROUND/OBJECTIVES - Due to the high costs and excess mortality associated with multimorbidity, there is a need to develop approaches for delaying its progression. High blood pressure (BP) is a common chronic condition and a risk factor for many additional chronic conditions, making it an ideal target for intervention. The purpose of this analysis was to determine the association between the level of sustained BP...

BACKGROUND - Endothelial progenitor cells (EPCs) have the potential to protect against atherothrombotic event occurrences. There are no data to evaluate the impact of cilostazol on EPC levels in high-risk patients. METHODS - We conducted a randomized, double-blind, placebo-controlled trial to assess the effect of adjunctive cilostazol on EPC mobilization and platelet reactivity in patients wi...

The benefits and harms of dual antiplatelet therapy (DAPT) continuation with aspirin and clopidogrel beyond 1 year after percutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation for high ischemic or bleeding risk patients remain unclear. All consecutive patients undergoing PCI were prospectively included in the Fuwai PCI Registry from January 2013 to December 2013. We evaluated 7521 patients...
Acute Myocardial Injury in Patients Hospitalized With COVID-19 Infection: A Review
Original Research | By S Saeed, J Smith, K Grigorya et al.
BACKGROUND - In patients with significant tricuspid regurgitation (TR) the conventional markers for the assessment of right ventricular (RV) systolic function may be less accurate. Tricuspid annular plane systolic excursion (TAPSE) indexed to systolic pulmonary artery pressure (SPAP) (TAPSE/SPAP) may be prognostically useful in pulmonary hypertension and left ventricular dysfunction. Our aim was to explore its use in pa...
