NCT02538861

Brief Summary

This is a prospective open label two arms clinical trial. ARM-A patients will receive the standard of care diagnostic test at Baptist Hospital Main (BHM), which includes Single Photon Emission Computed Tomography (SPECT) imaging, while ARM-B patients will be randomized sequentially into two groups; Group-1 will receive CT Angiography and CT myocardial perfusion with new Revolution CT scanner (General Electric Healthcare) while the Group-2 will receive SPECT imaging test; both groups of ARM-B at West Kendall Baptist Hospital (WKBH). The primary hypothesis is that the combined evaluation of CT angiography with CT myocardial perfusion is more efficient in detecting or excluding acute coronary syndrome resulting in early discharge and decrease length of stay of patients from the Emergency Department (ED) compared to a strategy with SPECT alone. The secondary hypothesis is that a strategy with CTA/CTP can reduce direct patient care costs and potentially improve patient outcomes in the same patient population when compared to a strategy with SPECT imaging alone. The main purpose of this study is to have a definite ED chest pain admission triage, which will help to reduce the length of stay and direct patient cost. This approach will reduce the economic burden in intermediate risk group patients as well. We had a Baptist statistician run the numbers. This study will provide important preliminary data to guide clinical implementation of CTP/CTA in clinical practice. We divided arm B into two groups as the CT protocol might be different at each hospital, so we want to reduce bias as a result of variation in clinical patterns in the different hospitals. Also, we kept 50 patients in arm A (Baptist hospital) to have a control group at the hospital level.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Length of stay

    The average length of stay will be calculated in both study arms. Currently patients have 24 hours of stay at hospital in the chest pain observation unit. We expect and propose that with this new study the length of stay will be reduce to less than 14 hours.

    First 24 to 72 hours

Secondary Outcomes (1)

  • Direct patient costs

    First 24 to 72 hours

Inclusion Criteria: * \> 35 years of age * Patient had an episode of chest pain at rest or during exercise within the past 24 hours * Patient is classified as Level 3 Baptist Chest Pain Protocol or the patient is classified as "Level 4" and has either a 40-70% stenosis by coronary CT angiography, an Agatston Calcium Score \>400, or non-evaluable segments in coronary CT angiography * Women of childbearing potential have a negative pregnancy test * Patient understands the study requirements and procedures and provides written informed consent before any study specific test or procedures * Patient is willing to comply with the specified follow-up telephone call Exclusion Criteria: * Patient is classified as Level 1, Level 2, or Level 5 in the Miami Baptist Chest Pain Protocol * Known allergy to iodinated contrast agent or creatinine \>1.5mmol/L * Atrial Fibrillation, Flutter or irregular heart rhythm * Known history of severe asthma * Body Mass Index \>45 * Patients in unstable conditions

You may qualify if:

  • The patient is \> 35 years of age.
  • The patient had an episode of chest pain at rest or during exercise within the previous 24 hours.
  • The patient is classified as "Level 3" in the 5-Level Miami Baptist Chest Pain Protocol (Cury R et al.
