Heavy Metals, Angiogenesis Factors and Osteopontin in Coronary Artery Disease (CAD)

Austria200 participantsStarted 2010-09

Plain-language summary

The present study aims is to investigate: 1. whether patients suffering from acute resp. chronic ischemic heart disease show higher levels for cadmium (Cd), lead (Pb) and mercury (Hg) than local and international reference levels suggest; 2. the correlation between severity of coronary artery disease and angiogenic and angiostatic factors (endostatin-ES, angiostatin-AS, VEGF-vascular endothelial growth factor, osteopontin-OPN) The patient population consists of about 270 female and male patients suffering either acute or chronic ischemic heart disease (AIHD:ICD-10 I21; CIHD: ICD-10 I25). 3. whether patients suffering CAD and valve calcification (mitral annulus, aortic valve) show higher levels of endostatin, angiostatin, osteopontin and VEGF compared to patients with CAD but without valve (annulus) calcification The measurement of cadmium (urine), lead, mercury, zinc, endostatin, angiostatin, VEGF (serum) and osteopontin (plasma) in patients with angiographically verified coronary artery disease are in the fore. Furthermore, basic laboratory diagnostics as well as data from coronary angiography and echocardiography will be collected. Additionally, the investigators will inquire heavy metal exposition during life by an interview. Recruitment will be done during the in-patient stay at the General Hospital of Vienna, Medical University of Vienna.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
