National Director of Vascular Surgery and Endovascular Therapy, Tenet Healthcare Corporation, Delray Medical Center, Delray Beach, FL, USA; Professor of Surgery, Charles E. Schmidt College of Medicine, Florida Atlantic University, Boca Raton, FL, USA. Electronic address:

Objective: Antiplatelet drug resistance is associated with periprocedural ischemic complications in patients undergoing intravascular stent implantation. Nonresponders are subject to increased risk of stent thrombosis and in-stent stenosis, and high on-treatment platelet reactivity (HTPR) is present in up to 44% of patients taking clopidogrel, a widely-used component of dual antiplatelet therapy (DAPT). Evidence points to ticagrelor as a viable alternative to overcome HTPR on clopidogrel. Read More

Continuing versus suspending angiotensin-converting enzyme inhibitors and angiotensin receptor blockers: Impact on adverse outcomes in hospitalized patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Am Heart J 2020 May 13. Epub 2020 May 13.

D'Or Institute for Research and Education (IDOR), Rio de Janeiro, Brazil.

Background: Angiotensin-converting enzyme-2 (ACE2) may increase due to upregulation in patients using angiotensin-converting enzyme inhibitors (ACEI) and angiotensin receptor blockers (ARB). Because renin-angiotensin system blockers increase levels of ACE2, a protein that facilitates coronavirus entry into cells, there is concern that these drugs could increase the risk of developing a severe and fatal form of COVID-19. The impact of discontinuing ACEI and ARBs in patients with COVID-19 remains uncertain. Read More

No evidence for amyloid pathology as a key mediator of neurodegeneration post-stroke - a seven-year follow-up study.

BMC Neurol 2020 May 8;20(1):174. Epub 2020 May 8.

Institute of Clinical Medicine, University of Oslo, Oslo, Norway.

Background: Cognitive impairment (CI) with mixed vascular and neurodegenerative pathologies after stroke is common. The role of amyloid pathology in post-stroke CI is unclear. We hypothesize that amyloid deposition, measured with Flutemetamol (F-Flut) positron emission tomography (PET), is common in seven-year stroke survivors diagnosed with CI and, further, that quantitatively assessed F-Flut-PET uptake after 7 years correlates with amyloid-β peptide (Aβ) levels in cerebrospinal fluid (CSF) at 1 year, and with measures of neurodegeneration and cognition at 7 years post-stroke.

Cognition in the First Year After a Minor Stroke, Transient Ischemic Attack, or Mimic Event and the Role of Vascular Risk Factors.

Front Neurol 2020 21;11:216. Epub 2020 Apr 21.

Functional Neuroimaging Laboratory, School of Psychology, University of Newcastle, Newcastle, NSW, Australia.

Cognitive impairment following a minor stroke or transient ischemic attack (TIA) is common; however, due to diagnostic difficulties, the prevalence and underlying cause of impairment remain poorly defined. We compared cognition in patients after a minor stroke, TIA, or mimic event at three time points in the first year following the event. We examine whether cognitive impairment occurs following these events and whether this impairment differs based on the event type. Read More

Critique on the Use of Early Short-Term Dual Antiplatelet Therapy Following Minor Acute Cerebral Ischemic Events.

Cerebrovasc Dis 2020 May 5:1-7. Epub 2020 May 5.

Department of Neurology, Cerebrovascular Division, State University of New York Downstate Medical Center, Brooklyn, New York, USA.

Background: Two recent cerebrovascular studies, Clopidogrel (Clo) in High-risk patients with Acute Nondisabling Cerebrovascular Events (CHANCE) and Platelet-Oriented Inhibition in New TIA and minor ischemic stroke (POINT), have purportedly demonstrated the superiority of early dual antiplatelet therapy (DAPT), using aspirin (ASA) plus Clo, in comparison to ASA alone following the occurrence of acute minor cerebral infarction or transient ischemic attack. However, limitations to these trials exist that may not have been adequately explored and presented in the literature, and which may impact the overall efficacy and benefit of DAPT in these situations. Herein we provide a detailed and extensive critique of these 2 trials and of a combined analysis, with particular attention to study data and analyses pertaining to hemorrhagic complications.

General lifestyle interventions on their own seem insufficient to improve the level of physical activity after stroke or TIA: a systematic review.

BMC Neurol 2020 May 1;20(1):168. Epub 2020 May 1.

Department of Rehabilitation, Physiotherapy Science & Sport, UMC Utrecht Brain Center, University Medical Center Utrecht, Utrecht University, Utrecht, The Netherlands.

Background: Insufficient amounts of physical activity is a risk factor for (recurrent) stroke. People with a stroke or transient ischemic attack (TIA) have a high risk of recurrent stroke and have lower levels of physical activity than their healthy peers. Though several reviews have looked at the effects of lifestyle interventions on a number of risk factors of recurrent stroke, the effectiveness of these interventions to increase the amounts of physical activity performed by people with stroke or TIA are still unclear.
