Cardiovascular nursing on human genomics: what do cardiovascular nurses need to know about congestive heart failure?

Pharmacogenomics in the nursing literature: an integrative review

BACKGROUND

Pharmacogenomics is a rapidly growing component of personalized health care, and nurses must be competent to deliver genomic-focused nursing care.

METHODS

We conducted an integrative review of pharmacogenomics in the nursing literature. A comprehensive search of the nursing literature was conducted using the key words pharmacogenomics and pharmacogenetics. A total of 47 unique articles were included.

RESULTS

Articles represented mainly narrative reviews, with limited discussions of the implications for nursing practice, education, or research. As such, they provide limited direction for advancing either clinical practice or scientific inquiry.

CONCLUSIONS

This review serves as a call to action for more systematic and empirical publications addressing pharmacogenomics in nursing practice, education, and research. Nurses must be involved in and contribute to interdisciplinary conversations and burgeoning clinical practice initiatives related to pharmacogenomics.

Effects of an angiotensin 2 receptor blocker plus diuretic combination drug in chronic heart failure complicated by hypertension

The effects of 24 weeks' treatment with an angiotensin 2 receptor blocker (ARB)/diuretic combination drug were investigated in an open-label study of 61 patients with stabilized chronic heart failure. Renin-angiotensin-aldosterone system inhibitors were replaced with a tablet containing hydrochlorothiazide 6.25 mg plus candesartan 8 mg, administered orally, once daily, in patients with systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg while under optimal treatment. Both SBP and DBP declined significantly during the ARB/diuretic combination treatment. Diuretics administered previously were discontinued during the study period in 15 patients, decreasing the number of drugs being taken. During ARB/diuretic combination treatment, the blood urea nitrogen level worsened but no significant changes were noted in potassium or estimated glomerular filtration rate, which had been a matter of concern. Additionally, the level of brain natriuretic peptide, an indicator of the severity of heart failure, was improved, indicating effectiveness and safety of the ARB/diuretic combination drug.
