Invasive Strategy Demonstrates Better Health Status Outcomes in Ischemia Study

A new study on ischemia and vascular diseases has shown that an invasive strategy is more effective in improving health status outcomes than a conservative approach. The study, led by researchers at Saint Luke's Mid America Heart Institute, analyzed data from the ISCHEMIA trial, which compared the health status outcomes of patients with chronic coronary disease who received either a conservative strategy or an invasive strategy, including percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).

Key Takeaways:

  • The invasive strategy demonstrated better health status outcomes than the conservative strategy in patients with chronic coronary disease.
  • Patients treated with CABG showed a higher Seattle Angina Questionnaire-7 summary score (SAQ-SS) and angina frequency score (SAQ-AF) than those treated with PCI.
  • At 1 year, patients treated with CABG had a higher SAQ-SS and SAQ-AF than those treated with PCI, but no significant differences were observed at 3 years.
  • Risk-adjusted analyses showed that PCI and CABG were associated with a higher SAQ-SS and SAQ-AF at 1 and 3 years compared to conservative management.
  • Study authors stated that better angina relief with CABG than PCI was seen at 1 year, but not 3 years.

Statistics:

  • SAQ-SS in the conservative, PCI, and CABG groups increased by 9.9 +/- 18.1, 15.7 +/- 19.3, and 16.1 +/- 19.1 points at 1 year, respectively.
  • Freedom from angina in the conservative, PCI, and CABG groups was noted in 61.4%, 73.3%, and 82.4% at 1 year, respectively.
  • At 3 years, more patients in the CABG group were free from angina (81.4%) compared to the conservative (70.4%) and PCI (76.1%) groups.
