Common physical symptoms such as fatigue, chest pain and lower back pain are related to the perception of everyday smells, University of Nottingham researchers will tell delegates at a health psychology conference on campus.

Chest pain due to a shortage of blood in the heart, known as angina, is a condition that affects millions of Americans. The most recently approved new pharmaceutical approach to treat chronic angina is a novel drug called ranolazine, which was approved in 2006 for use as second line therapy in patients who continue to experience angina despite treatment with another class of anti-anginal medication.

Patients with acute coronary syndromes (ACS), such as heart attack and recent-onset chest pain, remain at considerable risk of experiencing further serious cardiovascular problems despite improvements in care. HDL ("good" cholesterol) has properties that may protect these patients from further complications by reducing plaque in their coronary arteries.
