Alternative Risk Markers in Coronary Artery Disease (ARMCAD)

This study is currently recruiting participants.

ClinicalTrials.gov Identifier: NCT00403351
  Purpose

Estimating the risk of future cardiovascular events such as death, stroke and myocardial infarction using traditional risk factors (such as age, gender, smoking, diabetes, hyperlipidaemia and hypertension) is well accepted in patients with and without existing cardiovascular disease. These estimates are based on a number of robust observational studies, including the original Framingham study. While these methods apply reasonably well on a population level their application to the individual patients is not always straightforward. In addition risk charts, such as those published by the Joint British Societies and American Heart Association may underestimate risk in certain groups, notably diabetics and patients of Indo-Asian background, whilst overestimating risk in others (by as much as 50% in some studies).

Further study details as provided by Monash University:

Biospecimen Retention:   Samples Without DNA

Biospecimen Description:

Serum specifically for future cardiac biomarkers


Estimated Enrollment:   500
Study Start Date:   October 2006
Estimated Study Completion Date:   May 2009

Groups/Cohorts
ARM-CAD 1
Cross-sectional analysis using coronary angiogram results
ARM-CAD 2
Prospective cohort for incident cardiovascular events and mortality

Detailed Description:

A number of variables including clinical, biochemical, and enzymatic have been evaluated to see if they add to conventional "risk-reduction" models such as Framingham and if so to understand if they may be used in routine clinical practice.

The aim of this study is to assess several known and a few novel risk-factors (heart rate variability, pulse wave analysis, high-sensitivity CRP and BNP) prior to planned elective coronary angiography (cross-sectional analysis) and in a prospective cohort of high and low-risk patients.

  Eligibility
Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample

Study Population
