Determining the extent of coronary luminal stenosis is a key factor in management of CAD. Methods presently used are costly and pose certain dangers, ranging from nephrotoxicity to death. Long Pentraxin or Pentraxin-3 (PTX3) has been used to predict survival or atherosclerotic process, but not to identify coronary stenosis. Calcium Score has been used to this end with some success. Methods: Individuals with chronic stable angina, without evidence of Myocardial Infarction (MI), who were categorized as intermediate-risk after completing a treadmill exercise test, according to Duke Protocol, underwent cardiac catheterization. In addition, blood samples were drawn for coronary sinus PTX3, and also PTX3, uric acid, high-sensitivity C-reactive protein (hs-CRP), cholesterol, glucose and High-Density Lipo-protein (HDL) in peripheral circulation. Calcium Scores were calculated using Agatston Score and non-contrast multi-slice CT scan. Participants were divided according to the number of stenotic coronary arteries (patent, one-, two-and three-vessel disease). Results: We found that PTX3 levels in coronary sinus and femoral vein correlated with each other, after log-transforming the values. Also we found that PTX3 levels and Calcium Scores differed among individuals with triple-vessel involvement and individuals without significant stenosis in any of coronary arteries. No significant differences were observed, regarding hs-CRP levels. Conclusion: PTX3 levels in periphery correlate with those in coronary arteries, and this variable can be measured with a less invasive procedure. In addition to Calcium Score, PTX3 levels are different in our four groups. The combined contribution of PTX3 and calcium score may help us identify individuals with significant coronary artery stenosis without needing to perform cardiac catheterization in a select group of patients.展开更多

For purpose of analysis and comparison, patients were classified in two groups: Initial shockable rhythm(ventricular tachycardia or ventricular fibrillation; n = 148, 72.9%) and initial non-shockable rhythm(n = 55, 27.1%). Baseline characteristics, coronary angiogram findings including Syntax Score and long-term survival rates were compared. RESULTS Sudden cardiac arrest was witnessed in 95.2% of cases, 66.7% were out-of-hospital patients and 72.4% were male. There were no significant differences in baseline characteristics between groups except for higher mean age(68.1 years vs 61 years, P = 0.001) in the nonshockable rhythm group. Overall 5-year mortality of the resuscitated patients was 37.4%. Patients with non-shockable rhythms had higher mortality(60% vs 29.1%, P < 0.001) and a worst neurological status at hospital discharge based on cerebral performance category score(CPC 1-2: 32.7% vs 53.4%, P = 0.02). Although there were no significant differences in global burden of coronary artery disease defined by Syntax Score(mean Syntax Score: 10.2 vs 10.3, P = 0.96) there was a trend towards a higher incidence of acute coronary lesions in patients with shockable rhythm(29.7% vs 16.4%, P = 0.054). There was also a higher need for ad-hoc percutaneous coronary intervention in this group(21.9% vs 9.1%, P = 0.03). CONCLUSION Initial shockable group of patients had a trend towards higher incidence of acute coronary lesions and higher need of ad-hoc percutaneous intervention vs nonshockable group.展开更多
