Diagnostic role of coronary calcium scoring in the rapid access chest pain clinic: prospective evaluation of NICE guidance.

Background: Coronary artery calcium (CAC) imaging by unenhanced computed X-ray tomography (CT) is recommended as an initial diagnostic test for patients with stable chest pain symptoms but a low likelihood (10-29%) of underlying obstructive coronary artery disease (CAD) after clinical assessment. The recommendation has not previously been tested prospectively in a rapid access chest pain clinic (RACPC).

Methods: We recruited 300 consecutive patients presenting with stable chest pain to the RACPC of three hospitals.

Therapies and nursing care of women with vulvar dermatologic disorders.

Vulvar dermatologic disorders are common among women, and prevalence increases with age. Treatment can provide women with symptomatic relief and can halt further progression of disease. Numerous therapies are available, and nurses who work with women across the life span should have an understanding of vulvar dermatologic disorders and therapeutic modalities.

Angioplasty of acquired pulmonary vein stenosis using covered stent.

One of the most serious complications post-catheter ablation of atrial fibrillation is the development of pulmonary vein stenosis. Controversy currently exists about the optimal treatment approach. The use of balloons and larger stents (~10 mm) results in more optimal outcome than just balloon angioplasty alone; however, even with stent implantation, recurrent restenosis may occur in 30 to 50% of patients.

Radiation dose of CT coronary angiography in clinical practice: objective evaluation of strategies for dose optimization.

Background: CT coronary angiography (CTCA) is an evolving modality for the diagnosis of coronary artery disease. Radiation burden associated with CTCA has been a major concern in the wider application of this technique. It is important to reduce the radiation dose without compromising the image quality.
