Genetics in the cardiovascular ICU

Halbmaier, Katie; Beutner, Katherine; Daniels, Chetana; More

Nursing2017 Critical Care. 12(5):14-24, September 2017.

There is currently an increase in the use of genetic technologies for risk assessment, diagnosis, treatment, and prevention of inheritable causes of mortality and morbidity. Patients and families are relying more and more on their nurse's understanding of genetics to guide their care. This article offers a review of the clinical applications of genetics relevant to the nurse practicing in the cardiovascular ICU.

Epigenetics: How environment influences gene activity

Pestka, Elizabeth L.; Meyer, Johanna M.

Nursing2017 Critical Care. 7(4):12-13, July 2012.

Epigenetics helps to explain ways that environmental factors such as foods, drugs, toxins, infections and stress influence the activity of genes. Understanding epigenetic influences can help you educate patients so they can make changes to improve their health.

Genetic aspects of migraine headaches

Pestka, Elizabeth L.; Nash, Virginia R.

Nursing2017 Critical Care. 7(2):16-18, March 2012.

Up to 90% of people with migraines have a family history of this condition, but genetic contributions to migraines are complex. Learn about the role of genetics in assessing and caring for a patient with migraines.

Genetic testing and the diagnostic puzzle of long QT syndrome

Harris, Katy M.; Messner, Penny M.; Pestka, Elizabeth L.

Nursing2017 Critical Care. 6(6):5-6, November 2011.

Twelve different genotypes of long QT syndrome, a potentially fatal cardiac disorder, have been identified. Genetic testing can determine which genotype a patient has, and help clinicians formulate an effective treatment plan.

Understanding Huntington disease

Sportsman, Nadine E.; Pestka, Elizabeth L.

Nursing2017 Critical Care. 6(3):10-11, May 2011.

Understanding the role of genetics can help you recognize Huntington disease in a patient with progressive motor disability.

Using genetic testing to guide warfarin therapy

Ungerer, Lisa L.; Pestka, Elizabeth L.; Messner, Penny K.

Nursing2017 Critical Care. 6(2):6-7, March 2011.

Identifying a therapeutic dose of warfarin for a patient is important, especially in the initial dose adjustment phase, because dosing is so variable, has a very narrow therapeutic index, and can cause life-threatening complications. Find out about two genes that can affect a patient's metabolism of warfarin.
