About this study

Official title: Reduction in YEllow Plaque by Aggressive Lipid LOWering Therapy. (YELLOW Trial)

The study will assess the regression of yellow plaque content of the lipid pool after aggressive lipid therapy by utilizing NIR spectroscopy. Statin therapy using Rosuvastatin 10-40 mg will be compared to the statin therapy of either Atorvastatin or Simvastatin. This is a single site study. A total of 100 subjects will randomized, of which 40 will receive intensive lipid therapy (Rosuvastatin 40mg) and 40 will receive standard care lipid lowering therapy.

Read the detailed description

Coronary artery disease (CHD) remains to be a leading cause of death in most countries (1) (2). It is well known that reducing cholesterol level by statin therapy is associated with significant reduction in plaque burden. REVERSAL (3) and ASTEROID (4) trials showed that in patients with coronary artery disease lipid-lowering with atorvastatin or rosuvastatin respectively reduced progression of coronary atherosclerosis and even cause repression of some lesions. CHD clinical events are related to plaque instability due to lipid content within the atherosclerotic plaque. High dose atorvastatin has shown to reduce the plaque lipid contents on serial IVUS analysis at 12 months. Therefore reduction in lipid content and thereby the plaque burden by lipid lowering therapy may stabilize the plaque and reduce cardiovascular events. High sensitivity C-reactive Protein (HsCRP) is an inflammatory biomarker that independently predicts future vascular events. In JUPITER (5) trial rosuvastatin (Crestor) significantly reduced the incidence of major cardiovascular events in apparently healthy people with elevated HsCRP. IVUS was utilized to demonstrate change in coronary artery vessel wall morphology over a relatively short period of time, but provided no data on the lipid content in the vessel wall. The application of NIR spectroscopy to identify lipid deposition within coronary arteries has been validated in ex vivo studies. Infrared spectra are collected as follows: Light of discrete wavelengths from a laser is directed onto the tissue sample via glass fibers. Light scattered from the samples is collected in fibers and launched into a spectrometer. The plot of signal intensity as a function of wavelength was used to develop chemometric models to discriminate lipid-cores from non-atherosclerotic tissue, and from atherosclerotic tissue that is predominantly fibrotic and from blood elements.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Lipiscan - Lipid Core Burden Index (LCBI)

    The regression of yellow plaque content from the atherosclerotic lipid pool after statin therapy by utilizing NIR spectroscopy as compared from baseline to 6-8 weeks after intervention. Spectroscopic information obtained from raw spectra was transformed into a probability of lipid core that was mapped to a red-to-yellow color scale, with the low probability of lipid shown as red and the high probability of lipid shown as yellow. Analyses were performed offline using the Matlab-based software, as previously published. Yellow pixels within the analyzed segment were divided by all viable pixels to generate the lipid-core burden index (LCBI). The maximal value of LCBI for each nonculprit obstructive lesion was recorded and used for comparison.

    Measured: at baseline and at 6-8 weeks after intervention

  2. LCBI4mm Max

    LCBI4mm max = change in lipid-core burden index at the 4-mm maximal segment. Spectroscopic information obtained from raw spectra was transformed into a probability of lipid core that was mapped to a red-to-yellow color scale, with the low probability of lipid shown as red and the high probability of lipid shown as yellow. Yellow pixels within the analyzed segment were divided by all viable pixels to generate the lipid-core burden index (LCBI). The maximal value of LCBI for each nonculprit obstructive lesion was recorded and used for comparison.

    Measured: at baseline and at 6-8 weeks after intervention

  3. Change in LCBI4mm Max

    Change in LCBI4mm max at 6-8 weeks after intervention as compared to baseline. LCBI4mm max = change in lipid-core burden index at the 4-mm maximal segment.

    Measured: at baseline and at 6-8 weeks after intervention

  4. Change in LCBI, Lesion

    Change in LCBI at 6-8 weeks after intervention as compared to baseline

    Measured: at baseline and at 6-8 weeks post intervention

Secondary outcomes (6)
  1. Intravascular Ultrasound (IVUS) Parameters

    Change in atheroma volume and lumen CSA on IVUS as related to change in yellow plaque index as compared from baseline to 6-8 weeks after intervention.

    Data not analyzed. Data not available.

    Measured: at baseline and at 6-8 weeks after intervention

  2. Fractional Flow Reserve (FFR) Value

    Change in FFR as related to change in yellow plaque index as compared from baseline to 6-8 weeks after intervention. Fractional flow reserve (FFR), defined as the ratio of maximum flow in the presence of a stenosis to normal maximum flow, is a lesion-specific index of stenosis severity that can be calculated by simultaneous measurement of mean arterial, distal coronary, and central venous pressure.

    Measured: at baseline and at 6-8 weeks after intervention

  3. Diameter Stenosis

    Percentage stenosis of vessel diameter in the analysis segment of nontarget lesions as measured by angiography that remained >70%, after successful PCI of the target lesion.

    Measured: Baseline and 6-8 weeks post intervention

  4. Post PCI Cardiac Enzymes

    Correlation of yellow plaque index with post procedure CK-MB, Troponin-I release.

    Measured: at 6-8 weeks after intervention

  5. Major Adverse Cardiac Events (MACE)

    MACE defined as a combined clinical endpoint of death, MI (Q wave or non Q-wave with CK-MB >3 times above the upper normal limit (48 U/L), urgent revascularization or stroke at 30 days and 1 year. Details reported in adverse events section.

    Measured: at 6-8 weeks after intervention

  6. Blood Chemistry - HsCRP

    Correlation of yellow plaque index with changes in levels of blood HsCRP as compared from baseline to 6-8 weeks after intervention

    Measured: at baseline and at 6-8 weeks after intervention
