Coronary　heart　disease　(CHD)　is　a　serious　complication　of　hypertension　disease　(HD).　But　this　complication　can　not　get　timely　detected,　which　is　likely　to　cause　serious　events　and　result　in　extremely　high　disability　rates　and　mortality.　Therefore,　early　screening　is　important　to　provide　early　intervention　to　prevent　the　occurrence　of　serious　events.　Tongue　manifestation　can　reflect　the　condition　of　the　heart.　In　this　paper,　we　applied　tongue　hyperspectral　imaging　to　the　early　screen　of　the　HD　complicated　with　CHD　patients.　Hyperspectral　data　of　154　samples　were　collected　from　the　department　of　cardiology.　The　wavelength　range　of　hyperspectral　data　is　377.　38　similar　to　1　049.　1　nm.　The　correlated　clinical　diagnosis　was　also　recorded.　Hyperspectral　data　of　the　tongue　was　separated　into　five　parts　according　to　the　Chinese　medicine　theory,　which　included　tongue　tip,　tongue　left,　tongue　middle,　tongue　right　and　tongue　root.　There　are　maximum　and　minimum　values　at　509.6,　561.2,　540.　5　and　576.　7　nm.　Moreover,　this　is　consistent　with　the　light　absorption　characteristics　of　hemoglobin.　Then　different　tongue　parts　of　the　two　groups　were　compared.　The　T-test　results　showed　that　there　were　significant　differences　between　tongue　tip　and　tongue　middle　in　the　wavelength　region　of　500　similar　to　600　nm.　Backpropagation　artificial　neural　network　(BPANN)　was　employed　as　an　identification　method　for　the　screening　whether　or　not　complicated　with　CHD.　The　optimal　results　of　screening　model　are　obtained　with　an　accuracy　of　84.　78%　,　sensitivity　of　86.　95%　,　and　specificity　of　82.　61%　,　respectively.　Experiment　results　showed　that　there　were　significant　differences　between　HD　and　HD-CHD　hyperspectral　data,　and　hyperspectral　imaging　of　the　tongue　provides　a　possible　way　for　screening　HD　complicated　with　CHD　among　HD　patients.
