  • Researchers compare cardiac MRI, SPECT in diagnosing CAD
    In patients with known or suspected ischemic coronary artery disease, perfusion cardiac MRI is more sensitive but less specific than SPECT, according to a Swiss study published in the European Heart Journal. The researchers compared the diagnostic capability of cardiac MRI and SPECT, with invasive angiography as the standard method, in 533 patients at 33 facilities. Researchers said their results support those of previous studies and provide evidence of MRI's ability to correct for cardiac and respiratory movement. (3/7) LinkedInFacebookTwitterEmail this Story
  • Meta-analysis looks at ECG's predictive value for sudden cardiac death
    Electrocardiogram alone or with echocardiogram had high negative predictive value, but had varied positive and false-positive predictive rates for detecting pediatric sudden cardiac death, according to a meta-analysis in Pediatrics. For hypertrophic cardiomyopathy, long QT syndrome and Wolff-Parkinson-White syndrome, researchers noted that the summary phenotypic prevalence rates were 45, seven and 136 per 100,000 asymptomatic children, respectively.

  • Research shows cardiac patients may not understand their disease
    A review of study data found many patients who had cardiovascular procedures did not fully understand their conditions. Health care providers should take that into account when giving discharge instructions, according to University of Nebraska Medical Center researchers. The study in the Journal of Cardiovascular Nursing said nurses should provide "evidence-based education and counseling" and find out whether patients understand their disease, procedure and recovery.

  • ONC chief takes issue with study disputing EHRs' cost benefits
    A study in Health Affairs questioned whether EHRs would cut costs after finding doctors with e-access to imaging and diagnostic results ordered more tests, but a federal official questioned those findings. National HIT Coordinator Dr. Farzad Mostashari disputed the study, saying it was based on data gathered before the meaningful use program started and failed to address EHRs' capabilities for clinical decision support and data exchange.
