The purpose of this research study is to perform serial magnetocardiographs (MCG)and cardiovascular risk factor assessments on individuals with no symptoms or history of heart disease. This small sized study of MCG in healthy individuals will allow for data collection for power analysis for a larger prospective trial.

Volunteers are not compensated or paid.


Study Type: Observational
Official Title: Magnetocardiography (MCG) in Asymptomatic Individuals - Pilot Trial

Further study details as provided by Cedars-Sinai Medical Center:

Estimated Enrollment: 40
Study Start Date: December 2007
Estimated Study Completion Date: December 2009
Estimated Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)

Subjects without any cardiovascular risk factors:

  1. Age ≥ 45 in men; Age ≥ 55 in women.
  2. Hypertension: BP > 140/90 mmHg or on BP meds.
  3. Diabetes Mellitus: Known fasting blood sugar >126 mg/dl or on DM meds.
  4. Dyslipidemia: On lipid lowering medication or LDL ≥ 160 mg/dl in absence of other risk factors; ≥ 130 mg/dl if other non-diabetic risk factors; ≥ 100 mg/dl if diabetic. Known HDL < 40 mg/dl.
  5. Cigarette smoking (past or present).
  6. Family history of premature CAD in first degree relatives: Age < 55 in men; Age < 65 in women.
Subjects with 1 cardiovascular risk factor (listed above)
Subjects with 2 cardiovascular risk factors (listed above)
Subjects with more than 2 cardiovascular risk factors (listed above)

Detailed Description:

The Magnetocardiography (MCG) has been approved by the U.S Food and Drug Administration (FDA) as a tool to measure the heart's magnetic field.However, it is not yet approved for the specific diagnosis of coronary artery disease.

The MCG scan is entirely non-invasive, rapid and no risk, since it does not require stress provocation, radiation, or use of medication or contrast.

In this study, the MCG will be used to compare the scans of normal, healthy volunteers to those which have been previously or are currently being collected in subjects with known heart disease.
