In addition, other preventive steps you can take include: tea and foods high in B and E vitamins, such as green leafy vegetables and fish can reduce heart disease in women; low dose aspirin and statins can reduce heart disease risk; regular ECG stress test may not give the correct information about your heart; further testing such as stress echocardiogram, stress thallium, or cardiac catheterization may be required; Ultrafast CT and MRI are only pre-screening tests. Do not leave the ER without EKG and cardiac enzyme test (CPK or troponin).
