Clinical considerations in cardiac stress testing

For Better and For Worse: Quality of Life Impaired in HF Patients as well as in Their Partners

Background: Quality of Life (QOL) is known to be impaired in patients with Heart Failure (HF). The involvement of a key person, most often the spouse, enables the HF patient to manage the medical regimen and therefore to sustain Quality of Life (QOL). Yet little is known on the impact of caring for an HF patient on the QOL of the caregiving partner. This study aims to explore the QOL of partners of HF patients compared to the QOL of the patients.

Methods: The study population consisted of 38 couples of hospitalized HF patients and their partners. The Cantril Ladder of Life was used to rate QOL during hospitalization, with regard to the month prior to hospitalization and as projected 3 years in the future. Demographic and clinical variables were collected by patient interview and chart review.

Results: On a scale from 0–10, QOL scores of partners varied from 5.9 to 6.4. At some point the QOL score of partners was even lower than the QOL scores of HF patients. In the month prior to hospital admission the QOL of partners was significantly higher in comparison to the QOL of HF patients (6.1 vs. 4.9, respectively). However, this reversed during hospital admission, with QOL scores of partners being significantly lower compared to QOL scores of HF patients (5.9 vs. 6.8, respectively), even after correcting for age and gender.

Conclusion: In our study the QOL of partners of HF patients was low. Whether this is explicitly due to having to live with a HF patient is not clear. Further research on what partners actually do and the relationship between being a caregiver and QOL is necessary in order to support these partners in giving optimal care and support.

Practical Application of Educational Rhetoric: A Pathway to Expert Cardiac Nurse Practice?

Cardiac nursing takes place within various spheres of health care, reaching into primary, secondary and tertiary care within theses, cardiac expertise falls within four domains: health promotion, cardiac prevention and rehabilitation, acute, chronic and episodic care and palliative care. This paper sets out the possibility for a staged development of the cardiac nurse, which could promote homogeneity in role, skill and practice. A framework ('Expert Cardiac Nurse Pathway') for the United Kingdom, is proposed here, and views on its usefulness throughout Europe are sought.

Clinical competence in myocardial perfusion scintigraphic stress testing: general training guidelines and assessment

The suggestion by the National Institute for Clinical Excellence (NICE) to more than triple the number of myocardial perfusion scintigraphy (MPS) procedures carried out by the NHS each year is a challenge both in terms of numbers of gamma cameras available to carry out the scans and qualified staff to supervise stress tests. In the past, exercise and pharmacological stress testing have been supervised only by doctors but, increasingly, this is taken on by suitably trained non-medical professionals such as nurses, radiographers and clinical technologists. The expansion of the numbers of non-medical professionals qualified to supervise stress testing will be key to meeting NICE's recommendations. This paper sets out how potential new stressors should be identified, what their training should cover and discusses the standards of competence they should meet. It provides guidelines for training non-medical stressors to perform a safe and efficient stress test during MPS and advice for maintaining competency.

Should simultaneous exercise become the standard for adenosine myocardial perfusion imaging?

Concomitant low-level treadmill exercise with adenosine pharmacologic stress (AdenoEx) during radionuclide myocardial perfusion imaging has become commonly used in recent years, particularly in large-volume laboratories. A number of studies have demonstrated a beneficial impact of AdenoEx protocols. These benefits include decreased side effects, improved safety and patient tolerance, improved target-to-background ratios because of less subdiaphragmatic activity, and improved sensitivity and defect reversibility. In light of these benefits, recent reviews and guidelines call for the addition of low-level exercise to adenosine stress whenever possible.
