In both men and women, CAD is the most common cause of heart attacks, which occur when the blood supply in the heart is interrupted (these are also known medically as 'acute coronary syndromes').Before the menopause women appear to be protected from CAD; however, after the menopause that protection is lost. Also, those women who do suffer a heart attack have twice the risk of further heart attacks compared to men despite having the same treatment that works well in men. Biological differences between men and women are probably playing an important role in the way CAD develops. However, due to a lack of research there is currently little understanding of how the female body works in this area.Inflammation is the body's natural response to injury or infection. Importantly it is also involved in the development of CAD. Hormones such as oestrogen and testosterone are also likely to be contributory factors. We think the differences between the way these hormones and inflammation play a part in CAD in both men and women are important, but the role they play is not yet fully understood.In this study we wish to measure the 'markers' of inflammation in the blood of patients attending Barts Heart Centre with chest pain. We will also conduct questionnaires with these patients, to understand their hormone status and how parts of their medical history may be a contributory factor. For patients who have previously attended Barts Heart Centre will will contact them to conduct the questionnaire over the telephone only. We will combine this data with the data that is routinely collected during hospital admission. In this way we hope to understand whether inflammation together with hormone status plays an important role in CAD. Our hope is that through this research we will address an under researched area and find new ways of treating women and men with coronary artery disease., conditionsModule conditions: Coronary Artery Disease, conditions: Myocardial Infarction, conditions: Acute Coronary Syndrome, conditions: Atherosclerosis, conditions: Inflammation, designModule studyType: OBSERVATIONAL, designInfo observationalModel: CASE_ONLY, timePerspective: PROSPECTIVE, enrollmentInfo count: 6000, type: ESTIMATED, outcomesModule primaryOutcomes measure: Mortality, primaryOutcomes measure: Re-admission, primaryOutcomes measure: MACE, secondaryOutcomes measure: Relationship with specific MI types, secondaryOutcomes measure: Relationship with inflammation, eligibilityModule sex: ALL, minimumAge: 16 Years, stdAges: CHILD, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule, hasResults: False
