Non-invasive CV eval: Non-specific EKG changes during stress testing are common. Stress imaging (ECHO, nuclear or MRI) carries more weight as it allows the doctor to assess the flow of blood into different parts of the heart muscle and also assesses the 'Ejection Fraction', which is a measure of the strength of heart contractions, above 55% being normal. Coronary calcium scores assess heart artery blockage risk.
