The findings demonstrated on sixteen-slice spiral CT angiography were compared with those seen on selective coronary angiography. Results Among the 88 coronary arteries, in the evaluation of the coronary arteries by sixteen-slice spiral CT angiography, the sensitivity of the detection of coronary artery was 86.80%,the specificity was 86.20%,the positive predictive and negative predictive value was 76.47%,92.59%,respectively.
The stenosis of arteries < 50% was regarded as normal, and scored 0; one branch of coronary arteries with stenosis ≥ 50% was scored 1; accordingly, 2, 3 or 4 branches of coronary arteries with stenosis ≥ 50% would score 2, 3 or 4, respectively.
CONCLUSION: Inflammatory factor IL-1β could promote the gene expression of MMP-3 as the stable marker in human coronary arterial smooth muscle cells, and it may be one of the mechanisms of inflammation in acute coronary syndrome.
The subjects who underwent diagnostic coronarography and detailed examination included 274 patients with lesions in the left coronary artery and its branches and 50 subjects without pathological changes in the coronary arteries or left ventricle.
The mechanical shock to this artery produced by its separation prior to its subsequent use as an autologous arterial bypass graft for coronary arteries provokes a persistent spasm of its smooth muscle that lasts for at least 5 h.
Prinzmetal's angina, also known as Prinzmetal's variant or Prinzmetal's vasospastic angina is characterized by angina attacks caused by spasm of the great epicardial coronary arteries.
After regression of the symptoms and electrocardiographic changes, significant pathomorphologic changes of coronary arteries were excluded by coronary angiography.
Echocardiography in aortic dissection can detect an intimal flap, intimal tears, the true and false lumen, complications such as pericardial and pleural effusions, aortic insufficiency, and involvement of the coronary arteries.
