In this week’s View, Dr. Eagle discusses the association of blood viscosity with mortality among patients hospitalized with COVID-19, then looks at a systematic review and meta-analysis of beta-blockers and renin–angiotensin system inhibitors for preventing left ventricular dysfunction due to anthracyclines or trastuzumab in patients with breast cancer. Finally, Dr. Eagle summarizes an open-label, blinded-outcome, randomized non-inferiority trial that examined thrombectomy alone versus intravenous alteplase plus thrombectomy in patients with stroke.
