ABSTRACT
Objective To report the coronary angiographic features and in-hospital outcome in coronary artery disease(CAD) patients with rheumatoid arthritis(RA) who underwent percutaneous coronary intervention(PCI)with stent implantation.Methods The study group comprised 69 consecutive patients with RA who underwent PCI in Beijing Friendship Hospital between January 2009 and June 2017. Medical records were analyzed retrospectively including clinical basic material, coronary angiogram data, and the incidence of major adverse events in hospital.Results Fifty five patients(79.7％) had one or more traditional CAD risk factors. Multivessel disease was present in 73.9％ of the patients, and the average SYNTAX score was(31.6±7.2). Two bare metal stents and 143 drug eluting stents were implanted. 50 cases(72.4％) required implantation of long stents(stent length>30 mm) .There were 25 patients developed major adverse events(36.2％) during hospitalization, including 1 case of cardiac death, 2 cases of stent thrombosis, 5 cases of PCI related MI, 5 cases of heart failure, 5 cases of gastrointestinal bleeding and 10 cases of contrast induced nephropathy(2 cases comorbided acute heart failure).Conclusions Patients with RA and CAD may have severe coronary lesions.PCI in these patients tends to result in an increased rate of major adverse events in-hospital. Hence there is a need of early identification and early prevention in these patients during perioperative period.
ABSTRACT
<p><b>BACKGROUND</b>Coronary artery disease (CAD) is a leading cause of morbidity and mortality in patients with connective tissue diseases (CTDs). Risk factors and clinical characteristics in these patients are not equivalent to those in traditional CAD patients. The objective of this study was to report short- and long-term clinical outcomes in a consecutive series of patients with CTD who underwent percutaneous coronary intervention (PCI) with stent implantation.</p><p><b>METHODS</b>The study group comprised 106 consecutive patients with CTD who underwent PCI in Beijing Friendship Hospital between January 2009 and June 2012. Medical records were analyzed retrospectively including clinical basic material, coronary angiogram data, and the incidence of major adverse cardiac events (MACEs) during the short- and long-term (median 3 years) follow-up.</p><p><b>RESULTS</b>Ninety-two of the patients (86.8%) had one or more traditional CAD risk factors. Multivessel disease was present in more than 2/3 of patients (73.6%). The left anterior descending coronary artery was the most commonly affected vessel (65.1%). Five bare-metal stents and 202 drug-eluting stents were implanted. After a median follow-up period of 36 months, thirteen patients (12.3%) died from cardiac causes, the rate of stent thrombosis was 9.4%, and the rate of target vessel revascularization (TVR) was 14.2%. Multivariate analysis revealed that hypertension (hazard ratio [HR] = 3.07, 95% confidence interval [CI]: 1.30-7.24, P = 0.041), anterior myocardial infarction (HR = 2.77, 95% CI: 1.06-7.03, P = 0.04), longer duration of steroid treatment (HR = 3.60, 95% CI: 1.43-9.08, P = 0.032), and C-reactive protein level >10 mg/L (HR = 3.98, 95% CI: 1.19-12.56, P = 0.036) were independent predictors of MACEs.</p><p><b>CONCLUSIONS</b>Patients with CTD and CAD may have severe coronary lesions. PCI in these patients tends to result in an increased rate of stent thrombosis and TVR during long-term follow-up, which may be influenced by traditional and nontraditional risk factors.</p>

<p><b>OBJECTIVE</b>To evaluate the in-hospital outcome of patients with calcified chronic total occlusion (CTO) lesion underwent percutaneous coronary intervention (PCI).</p><p><b>METHODS</b>The clinic and lesion characteristics as well as acute PCI outcome were analyzed in 726 patients with calcified CTO [624 detected by coronary angiography (CAG) and 102 detected by intravascular ultrasound (IVUS)] and received PCI therapy from June 1995 to February 2007 in our department.</p><p><b>RESULTS</b>There were 728 diseased vessels with 732 lesions in these patients. Total procedure success rate (80.6% vs. 89.2%, P < 0.05) and the lesion success rate (80.2% vs. 88.2%, P < 0.05) were significantly lower in calcified CTO detected by CAG compared to that detected by IVUS. The causes of procedure failures in CAG detected patients were as follows: 87 guide failure, 21 balloon failure, 8 procedure related complications and 5 low TIMI blood flow (grade 2) at the end of PCI procedure. The causes of procedure failures in IVUS detected patients were as follows: 7 guide wire failure, 2 balloon failure, 1 procedure related complications and 1 patient with low TIMI blood flow (grade 2). The in-hospital major adverse cardiac events (MACE) rate was 1.1% in CAG detected calcified CTO and 1.0% in IVUS detected calcified CTO (P > 0.05).</p><p><b>CONCLUSION</b>PCI therapy resulted in satisfactory procedure success rate and in-hospital outcome for patients with calcified CTO and IVUS is helpful for further increasing the PCI procedure success rate in patients with calcified CTO.</p>
