NON- IN­VA­SIVE TEST TO CHECK FA­TAL HEART DIS­EASE

The Asian Age - - World -

CAR­DIAC MAG­NETIC RESONANCE CAN NON- INVASIVELY IDEN­TIFY THE SEVER­ITY OF HEART DIS­EASE

■ It also pre­dicts which cases are po­ten­tially fa­tal, sci­en­tists said

■ It is a non- toxic al­ter­na­tive to stress echocar­dio­grams, catheter­i­sa­tions and stress nu­clear ex­ams

■ 9,000 pa­tients who un­der­went CMR at seven Amer­cian hos­pi­tals were an­a­lysed for the data

■ 10 years of fol­lowup was done for the study

■ 3.4 times more risk of death for pa­tients with ab­nor­mal CMR scan if they had no his­tory of heart dis­ease

■ Strong as­so­ci­a­tion found be­tween ab­nor­mal stress CMR and mor­tal­ity af­ter ad­just­ing for age, sex, and car­diac risk fac­tors.

■ The tech­nol­ogy does not re­quire any ra­di­a­tion ex­po­sure

We know that CMR is ef­fec­tive at di­ag­nos­ing coro­nary artery dis­ease, but it rep­re­sents less than 1% of stress tests used. Lack of data on its pre­dic­tive value blocked its broader use. — Robert Judd, Duke Uni­ver­sity
