Diagnostic and prognostic value of minor elevated cardiac troponin levels for percutaneous coronary intervention-related myocardial injury:a prospective,single-center and double-blind study

Cardiac troponin-I （cTnI） and -T （cTnT） are sensitive and specific markers of myocardial injury. However, the role of increased cTnI and cTnT in percutaneous coronary intervention （PCI）-related myocardial injury remains controversial. In this prospective, single-center and double-blind study, we aimed to determine the diagnostic and prognostic value of cTnI as well as cTnT （cTns） in PCI-related myocardial injury in a Chinese population. A total of 1,008 patients with stable angina pectoris and non-ST-segment elevation acute coronary syndrome were recruited. The levels of cTnI and cTnT were examined before and after PCI. All patients were followed up for 26± 9 months to observe the incidence of major adverse cardiac events （MACEs）. Our results showed that post- PCI cTnI and/or cTnT levels were increased to more than the 99^th percentile upper reference limit （URL） in 133 （13.2%） patients, among which 22 （2.2%） were more than 5 × 99^th percentile URL. By univariate analysis, an elevation in cTns after PCI was not an independent predictor of increased MACEs, HR 1.35 （P = 0.33, 95% CI： 0.74-2.46）. In conclusion, our data demonstrate that the incidence of PCI-related myocardial injury is not common in a Chinese population and minor elevated cTns levels may not be a sensitive prognostic marker for MACEs.

Effect of a distal protection device on epicardial blood flow and myocardial perfusion in primary percutaneous coronary intervention

Objective: The beneficial effect of percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) has been well established, but there is the problem of no-reflow phenomenon which is an adverse prognostic factor in primary PCI. In the present study the effect of a distal protection device (PercuSurge GuardWire; GW) on epicardial blood flow and myocardial perfusion was evaluated. Methods and Results: Patients with AMI were randomly divided into 2 groups, the GW and the control groups. The GW group included 52 patients with AMI who underwent primary PCI with GW protection and the control group included 60 patients who underwent primary PCI without GW protection. Epicardial blood flow in the infarct-related artery (IRA) and myocardial perfusion were evaluated according to the thrombolysis in myocardial infarction (TIMI) flow grade and the myocardial blush grade (MBG). We found TIMI score of 3 was obtained significantly more frequently in the GW group (96%) than in the control group (80%). The MBG score of 3 was obtained also significantly greater in the GW group (65%) than in the control group (33%). Conclusion: Primary PCI with GW protection can significantly improve epicardial blood flow and myocardial perfusion.

Initial Experience on Anatomical Snuff Box Approach for Coronary Angiogram &Percutaneous Coronary Intervention in a Tertiary Care Center Nepal

Introduction: Coronary Angiogram and Percutaneous Coronary Interventions are commonly performed via the femoral route. Then, transradial coronary catheterization became a popular & default technique due to less vascular access site complications and bleeding as compared to femoral route. Distal puncture of the radial artery through the anatomical snuff box access, however, has recently been shown potential benefit, like comfort to patients and operators, as well as maintenance of blood flow through the superficial palmar arch, in case of radial artery occlusion. Our aim was to evaluate the safety and feasibility of this new approach. Methods: A cross-sectional observational prospective study of patients underwent invasive diagnostic or therapeutic coronary procedures through the distal trans-radial access and traditional radial access. The primary endpoints were to access difficulties and in-hospital access-site related complications. Results: In 2 months, 190 patients underwent coronary procedures, of which 82 (43%) were selected in both distal transradial & traditional radial group. In 2(2.4%) & 3 (3.6%) cases, distal radial & traditional radial access cannulation was unsuccessful respectively (p >0.05). The mean age was 57.7 ± 10 & 57.2 ± 10 years in successful distal transradial & traditional radial cases respectively. There were no any major vascular complications in distal transradial group while there were 2 vascular complications in traditional radial group (p > 0.05). Conclusions: Distal transradial access is feasible and safe in selected cases, when performed by experienced operators. Larger case series and randomized trials are required to determine its efficacy in reducing vascular complications when comparing to the traditional technique.

Objective： To investigate the regulation of High sensitive C-reactive protein（Hs-CRP） and WBC count in patients with coronary heart disease（CHD） by percutaneous transluminal intervention（PCI） and to discuss the mechanism of inflammatory reaction after coronary stenting. Methods：127 patients who received successful percutaneous transluminal coronary stenting, were divided into groups of stable angina（SAP）, unstable angina（UAP）, and acute myocardial infarction（AMI） according to their clinical types. Another 41 stable angina patients with more than 70% of coronary artery tenosis who did not receive PCI served as control. Serum Hs-CRP levels and WBC count were determined before intervention, 3 days and 7 days post PCI and the data were analyzed statistically by t-test. Results： There showed no difference in clinical baseline characteristics between groups. The serum Hs-CRP level and WBC count was gradually raised in the UAP and AMI group（how about SAP group, andhad no difference in CAG group and SAP group）. After PCI serum HsCRP levels and WBC counts were significantly higher in the SAP group than in the coronary angiography group（CAG） at 3 days and had no difference at 7 days. In the UAP and AMI group, the serum Hs-CRP level at 3 days and 7 days declined obviously, however serum WBC count did not decrease apparently. Conclusion： The serum Hs-CRP level and WBC count elevate transiently after PCI. There are different inflammatory reactions in different types of coronary heart diseases after coronary stenting procedure.
