Clinical Efficacies Of Percutaneous Coronary Intervention In Patients With Maintaining Hemodialysis Combined With Acute Coronary Syndrome

Objective: The aim of this study was to investigate the safety and efficacy of percutaneous coronary intervention (PCI) in patients maintaining hemodialysis complicated with acute coronary syndrome (ACS). Methods: 15 patients maintaining hemodialysis complicated with ACS were selected. PCI were performed on the patients. The coronary lesion was examined using coronary angiography (CAG). The renal functions, troponin and myocardial enzymes before and after surgery were tested. Results: 13 cases (86%) were successfully implanted stent, while 1 case was not because of the tiny vessels at the distal end of lesion, and 1 cases was not performed PCI for no existence of stenosis or occlusion. Postoperative monitoring of renal function showed no aggravation, and no major cardiac adverse events occurred during the follow-up period. Conclusion: Patients. maintaining long-term hemodialysis would prone to exhibit vascular calcification induced coronary artery occlusion because long-term calcium-phosphorus metabolism disorder can cause secondary hyperparathyroidism, thus often exhibiting such clinical manifestations as arrhythmia, chest tightness, and aggravated chest pain during dialysis, therefore, in-time dialysis after PCI could eliminate the contrast agent, so CAG and PCI were safe and feasible for the patients with dialysis, and the clinical efficacies were good.
