This paper emphasizes the design and practice of the gas and air preheating system with waste gas heat. The hot blast temperature reaches 1143 * and PCI rate is 101 kg/t under the conditions of single BF gas of 3250 kJ/m3and without oxygen enrichment.
Results~The total success rate of PCI procedure was 98.1 % (4579/ 4670) for all patients, and the patency rate of infarction related artery of emergency PCI was 98.2 % (825/840) in the patients with AMI onset within ~24 h.
Results: The values of QTd three days before PCI three days after PCI and one month after PCI were 39.46+ 14.85ms, 27.90+11.42ms and 26.85+9.66ms, respectively in patients with coronary artery disease.
Detection of abnormal myocardial perfusion is crucial to the prognosis of patients with coronary artery disease (CAD) after they have undergone percutaneous coronary intervention (PCI).
The effect of myocardial reperfusion was evaluated using the above mentioned three methods 15 min after PCI.
For those patients with acute or total occlusion, the levels of myocardial perfusion before and after PCI were similar, as determined by IC-MCE and visually analyzed from 61 segments (P >amp;lt; 0.05).
Thus, the IC-MCE method is of great value to coronary artery disease (CAD) patients undergoing PCI, especially for those with acute myocardial infarction (AMI).
It is challenging to undo early percutaneous intervention (PCI) in the elderly with acute coronary syndrome (ACS).
