Absence of preinfarction angina is associated with a risk of no-reflow phenomenon after primary coronary angioplasty for a first anterior wall acute myocardial infarction

BACKGROUND: No-reflow phenomenon after primary coronary angioplasty is associated with poorer left ventricular (LV) function and prognosis after acute myocardial infarction (AMI). The purpose of this study was to determine the clinical significance of preinfarction angina in the no-reflow phenomenon. METHODS AND RESULTS: A total of 40 patients with first anterior AMI were examined. All patients underwent primary balloon angioplasty or stenting within 12 h of the onset of AMI. No-reflow, defined as TIMI grade 2 flow or less without residual stenosis after angioplasty, was observed in 15 patients. Patients with no-reflow were older (67+/-9 vs. 58+/-10 years, P=0.006) and had a lower incidence of preinfarction angina (7% vs. 48%, P=0.01) than those without no-reflow. Patients with no-reflow had poorer LV function at predischarge and a higher incidence of pump failure, LV aneurysm, malignant ventricular arrhythmias or cardiac death during the hospital course in association with higher peak serum C-reactive protein levels (12.7+/-8.0 vs. 7.1+/-5.5 mg/dl, P=0.02). Multivariate analysis showed that the absence of preinfarction angina was a major independent determinant of no-reflow (RR=17.1, P=0.02). CONCLUSIONS: The absence of preinfarction angina is more frequently observed in patients with no-reflow. The beneficial effect of preinfarction angina on LV function may be explained, at least in part, by prevention of no-reflow after reperfusion.

hs-CRP is a potential predictor of no-reflow in patients with AMI after emergency PCI

The paper aims to determine whether the inflammation,a powerful risk factor that has been demonstrated for the development of coronary artery disease,plays a role in no-reflow phenomenon in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI).Methods We prospectively analyzed 656 patients with AMI after primary PCI.Based on post-PCI angiography data,patients were divided into two groups:the no-reflow group (TIMI=2,n =60) and the reflow group (TIMI=3,n =596).Results Our results showed that the inflammatory factors including leukocyte count (×109/L) (10.90±4.04 vs.9.12±2.98 P =0.002),hs-CRP (5.04±0.71 vs.4.70±0.75 P =0.001) and other factor platelet count (×109/L) (210.96±33.42 vs.196.41±46.06 P =0.033) in no-reflow group are significantly higher than those in reflow group,major adverse cardiac events happened in the patients with no-reflow are higher than in reflow patients no matter in hospital or at the end of follow-up.We also found the left ventricular ejection fraction (LVEF) dramatically decreased (58.65±9.34 vs.51.29±11.38,P＜0.001) and left ventricular end-diastolic dimension (LVEDD) significantly increased (49.94±6.75 mm vs.54.66±6.68mm,P＜0.001) in no-reflow patients at the end of follow-up.Conclusions Our results suggest that inflammation factors function in no-reflow phenomenon,and no-reflow is a serious complication after primary PCI which predicts poor left ventricular systolic functional recovery and mortality in patients with AMI.(J Geriatr Cardiol 2008;5:217-222)

Abstract：

Objective To observe serum C4a and platelet aggregation rates changes in acute myocardial infarction (AMI) patients before and after percutaneous coronary intervention (PCI)and association with the development of no-reflow phenomenon. Methods From June 2006 to August 2009, 119 AMI patients underwent PCI (28 cases of no-reflow group, 91 cases of reflow group)and 30 subjects with suspected coronary heart diseases and normal coronary angiography results (control group) were enrolled in this study. C4a and platelet aggregation rate were measured at 30 minutes before PCI, immediately after PCI,30 minutes,l hour,2 hour, and 6 months post PCI in AMI patients and at before coronary angiography in control subjects. Results The levels of serum C4a at 30 minutes prior to PCI in control, no-reflow, and reflow groups were similar(P ＞0. 05). Platelet aggregation rate at 30 minutes prior to PCI was significantly higher in no-reflow group and reflow group than in control group ( all P ＜ 0. 05 ). Serum C4a and platelet aggregation rates were significantly higher in no-reflow group at immediate, 30 minutes and 1 hour after PCI than at 30 minutes prior to PCI, two hours and 6 months after PCI ( all P ＜ 0. 05), and were significantly higher than in reflow group at immediate, 30 minutes and 1 hour after PCI ( all P ＜ 0. 05 ). Serum C4a and platelet aggregation rates were similar at different time points in reflow group ( all P ＞ 0. 05 ). The levels of C4a in no-reflow group at immediate, 30 minutes and 1 hour after PCI were positively correlated with platelet aggregation rates (r=0. 91,0. 79 ,0. 60 ,respectively ,all P＜0.01). Conclusion The transient increase on levels of C4a and platelet aggregation rate early post PCI are verified in no-reflow patients with AMI undergoing PCI.     

Angiographic no-reflow phenomenon as a predictor of adverse long-term outcome in patients treated with percutaneous transluminal coronary angioplasty for first acute myocardial infarction

OBJECTIVES: We sought to elucidate the long-term prognostic importance of angiographic no-reflow phenomenon after percutaneous transluminal coronary angioplasty (PTCA) for acute myocardial infarction (AMI). BACKGROUND: Angiographic no-reflow phenomenon, a reduced coronary antegrade flow (Thrombolysis in Myocardial Infarction [TIMI] flow grade < or =2) without mechanical obstruction after recanalization, predicts poor left ventricular (LV) functional recovery and survival in the early phase of AMI. We hypothesized that angiographic no-reflow phenomenon also predicts long-term clinical outcome. METHODS: We studied 120 consecutive patients with their first AMI treated by PTCA without flow-restricting lesions. The patients were classified as either no-reflow (n = 30) or reflow (TIMI-3) (n = 90) based on post-PTCA cineangiograms to follow up (5.8 +/- 1.2 years) for cardiac death and nonfatal events. RESULTS: Patients with no-reflow had congestive heart failure (p < 0.0001), malignant arrhythmia (p = 0.038), and cardiac death (p = 0.002) more often than did those with reflow. Kaplan-Meier curves showed lower cardiac survival and cardiac event-free survival (p < 0.0001) in patients with no-reflow than in those with reflow. Multivariate analyses disclosed that no-reflow phenomenon was an independent predictor of long-term cardiac death (relative risk [RR] 5.25, 95% confidence interval [CI] 1.85 to 14.9, p = 0.002) and cardiac events (RR 3.71, 95% CI 1.79 to 7.69, p = 0.0004). At follow-up, survivors with no-reflow had higher end-diastolic and end-systolic LV volume indices and plasma brain natriuretic peptide levels, and lower LV ejection fractions (p = 0.0002, p < 0.0001, p = 0.002, p < 0.0001, respectively) than did those with reflow, indicating that no-reflow may be involved in LV remodeling. CONCLUSIONS: Angiographic no-reflow phenomenon strongly predicts long-term cardiac complications after AMI; these complications are possibly associated with LV remodeling.
