Sildenafil Administration Improves Right Ventricular Function on 4D Flow MRI in Young Adults Born Premature
CONCLUSIONS: Despite reduced right atrial workload, metoprolol significantly depressed overall cardiac systolic function. Sildenafil, however, increased CI and improved RV function, as quantified by the direct flow fraction. The preterm heart appears dependent on HR, but sensitive to RV afterload manipulations.PMID:33861148 | DOI:10.1152/ajpheart.00824.2020

​BY FREDDIE IRIZARRY-DELGADO; VAROON KAKAIYA; & AHMED RAZIUDDIN, MDAn 86-year-old African-American woman was brought to the ED by her daughter after two days of nutritional neglect, abdominal pain, and altered mental status.

The patient had a history of diabetes mellitus type 2, DVT/PE, dementia, and early signs of parkinsonism.Her vital signs were remarkable only for tachypnea (24 bpm). Her troponin I was markedly elevated at 1.7 ng/mL. A D-dimer was ordered because of her history of unprovoked DVT/PE, and i...
