Cardiac Magnetic Resonance Imaging and Coronary Computed Tomography Angiography in Cardiomyopathy: Diagnostic and Prognostic Insights.

This review focuses on the key noninvasive cardiac imaging techniques, including coronary computed tomographic angiography (CCTA) and cardiac magnetic resonance imaging (CMR). It highlights essential publications pertinent to clinicians managing ischemic and nonischemic cardiomyopathy. CCTA provides an anatomical assessment that offers superior diagnostic accuracy compared to functional tests. It is a valuable tool for understanding the impact of nonobstructive coronary artery disease on patient outcomes. Additionally, CCTA is beneficial in defining the morphology of vulnerable plaque, which closely aligns with IVUS findings. It also demonstrates safety advantages, including reduced contrast volume and radiation dose and a lower risk of contrast‐induced nephropathy when used in post‐CABG besides conventional coronary angiograms. CMR provides invaluable insight into MI size and microvascular obstruction, critical for understanding a patient's prognosis. The assessment of scar tissue with CMR has become an essential tool for risk stratification and informs therapeutic decisions regarding the implantation of ICD. [ABSTRACT FROM AUTHOR]
