Brief Summary

Background: The prevalence of heart failure (HF) is rapidly rising in industrialized and developing countries. Though invasive coronary angiography (ICA) remains the gold standard for anatomical assessment of coronary arteries and luminal stenoses in these patients, alternatives have been sought. Computed tomographic coronary angiography (CTA) has emerged as an accurate non-invasive diagnostic tool for CAD and has been demonstrated to have prognostic value. Whether or not CTA can be used in patients with HF for diagnosis and to guide patient investigations and management is unknown. Acknowledging the aging population in industrialized counties, the increasing burden of healthcare and growing prevalence of HF, there is a need to identify non-invasive diagnostic tests that are cost-effective, readily available, safe and of sufficient accuracy to risk stratify patients and guide investigations and management. Methods: The proposed randomized controlled trial (RCT) will evaluate the clinical utility of computed tomographic coronary angiography (CTA) and investigate its potential benefit on resource utilization and health economics in patients with progressive or newly diagnosed heart failure (HF) of unknown etiology (i.e. ischemic versus non- ischemic) or in whom the definition of coronary anatomy is required for diagnosis and management. The experimental algorithm will be compared to invasive coronary angiography (ICA) Analysis of composite clinical events and major adverse cardiac events will be performed to determine the impact of these strategies upon patient outcomes. Accuracy of CTA in detection of coronary anatomy and obstruction will be assessed in patients undergoing ICA. It is expected that CTA will be a more cost-effective strategy for diagnosis; yielding similar outcomes with fewer procedural risks and improved resource utilization.

Outcome Measures

Primary Outcomes (1)

  • Resource Utilization

    Primary Outcome Measure: Resource Utilization: will be measured as detailed in Appendix A. Cost: the incremental cost of the diagnostic strategy using CTA will be the primary endpoint and will be estimated through regression methods.

    3 and 12 months

Secondary Outcomes (2)

  • Clinical Endpoints

    3 and 12 months

  • CTA Accuracy

    Baseline

Study Arms (2)

Standard imaging (coronary angiography)

ACTIVE COMPARATOR

Subjects will undergo a coronary angiogram as planned by their attending doctor

Other: Standard Imaging

Advanced imaging (CTA)

ACTIVE COMPARATOR

Subjects will undergo a CTA scan first. Based on the CTA results, subjects may or may not proceed to coronary angiography. CTA results will be reviewed by the attending physician.

Other: Advanced Imaging

Interventions

Also known as: Coronary Angiography

You may qualify if:

  • a documented history of left ventricular dysfunction (LVEF \<50%)
  • a documented history of Class ll-lV heart failure symptoms, in the preceding 12 months prior to enrollment, in whom the diagnosis of CAD is uncertain or the definition of coronary anatomy is required for diagnosis and management.

You may not qualify if:

  • Age \< 18 years or lack of consent,
  • Renal Insufficiency (GFR \< 45 ml/min);
  • Allergy to intravenous contrast agents;
  • Contraindication to radiation exposure (e.g. pregnancy);
  • Uncontrolled HR at time of scan (as per local clinical routine)
  • History of revascularization (CABG or PCI);
  • Atrial fibrillation, frequent atrial or ventricular ectopy (\> 1 / minute);
  • Unable to perform 20 second breath-hold;
  • CTA or ICA within the preceding 12 months
