BACKGROUND: Thrombus aspiration for ST-segment elevation myocardial infarction (STEMI) may improve myocardial perfusion. However, these favourable results called into a question by data indicating not only a lack of efficacy but a risk of potentially deleterious complications.AIM: To assess the effect of thrombus aspiration during the primary percutaneous coronary intervention (PPCI) on procedural angiographic results, stent characteristics, and major adverse cardiac and cerebrovascular events (MACCE).METHODS: All consecutive STEMI patients candidate for PPCI and admitted to Critical Care Department, Cairo University hospitals, managed either by thrombectomy before primary PCI (if thrombus score ≥ 3) or conventional PPCI, Six hundred seven subjects were enrolled in the study divided into Group with thrombectomy before PPCI (107 subjects, 18%), and group with Conventional PCI (500 subjects, 82%). ST-segment resolution, peak CK-MB, TIMI score, thrombus score, and MBG were assessed; stent number, diameter, length and stented segment were reported and follow up MACCE was reported (in hospital and 1-year post-intervention).RESULTS: Mean values for peak CKMB were less in thrombectomy group (228 ± 174 I/U vs 269 ± 186 I/U, p = 0.04), ST segment resolution ≥ 70% occurred in {63 subjects (58.9%) vs 233 (46.6%), p = 0.001} in thrombectomy vs conventional group respectively. TIMI score pre procedure was zero in (102 subjects (95%) vs 402 (80.4%), p = 0.001), while TIMI III post procedure was reported in (100 subjects (93.4%) vs 437 (87%), p = 0.06), MBG mean values were (2.4 ± 0.6 vs 2.0 ± 1, p = 0.001), thrombus score was higher in thrombectomy group (4.6 ± 0.4 vs 0.8 ± 1.7, p = 0.001) in thrombectomy vs conventional group respectively .Direct stenting was { 34 patients (31%) vs 102 patients (20%), p = 0.05} , mean stent diameter (2.7 ± 1.3 mm vs 3.5 ± 1.3 mm, p = 0.3), mean stent length was (19.9 mm ± 10 versus 22.7 mm ± 8 in p 0.01). mean stent number was (1.0 ± 0.5 vs 1.2 ± 0.6, p = 0.001), mean stented segment was (22.5 ± 13.5 vs 28.5 ± 15.2 mm, p = 0.001) in thrombectomy vs conventional group respectively. MACCE in hospital were reported in {9 subjects (8.4%) vs 70 (14%), p = 0.07)}. Follow up MACCE after 1 year reported in {6 subjects (5.6 %) vs 80 (16 %), p 0.= 4} in thrombectomy vs conventional group respectively.CONCLUSION: Thrombus aspiration before primary PCI (in a selected group with thrombus score ≥ 3) improves myocardial perfusion, suggested by better ST-segment resolution, TIMI flow, less peak CKMB and MBG, associated with a higher rate of direct stenting, shorter stent length, stented segments and less number of stents. Although thrombus aspiration was done in more risky patients (higher thrombus score) MACCE (in hospital and 1 year follow up) showed no statistical difference.

Background: Thrombus embolization during the Percutaneous Coronary Intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) is common and results in suboptimal myocardial perfusion and increased infarct size. Two strategies proposed to reduce distal embolization and improve outcomes after primary PCI is bolus intracoronary Abciximab and manual aspiration thrombectomy. There are several factors which influence the decision of primary PCI in a patient with AMI in developing countries. Cost of therapy and affordability is probably the most important factor. The additional cost for thrombus aspiration needs to be considered against the additional advantages in terms of better clinical outcome.  Objectives: To compare the use of a combination of intracoronary Abciximab with manual thrombus aspiration to intracoronary Abciximab alone, in patients with STEMI undergoing primary PCI. Patients and Methods:  This is a prospective observational study of patients with STEMI who underwent primary PCI between June 2018 to May 2019. A pre-approved study protocol was designed to determine the eligibility of STEMI patients to be included in the study. Patients with The patients have analysed in two groups: 84 patients received a combination of intracoronary Abciximab with manual thrombus aspiration  &  80 patients received intracoronary Abciximab alone.  The primary endpoint was the assessment of myocardial perfusion parameters namely Myocardial Blush Grade (MBG) in the culprit vessel & ST-segment resolution of >70% on ECG at 90 min after PCI. Secondary endpoints were the improvement in LV ejection fraction, cardiovascular mortality & recurrent MI at one-month post-procedure.  Results: Result of the 84 patients who received combination of intracoronary Abciximab with manual thrombus aspiration, the primary endpoints namely the myocardial blush grade (MBG) of 2/3 was achieved in 72 patients (90.74%) & ST-segment resolution of >70% at 90 min was seen in 66 patients (78.57%) (p<0.001). Of the 80 patients who received only intracoronary Abciximab without thrombus aspiration, MBG 2/3 was achieved in 38 patients (47.5%) & ST-segment resolution of >70% at 90 min was seen in 28 patients (35%). At one month of follow up the secondary endpoints namely the LVEF in the combination group improved from 43.42±3.73 to 47.88±4.16% (p=0.12)and in the Abciximab group improved from 44.78±3.34 to 46.20±3.63%. Recurrent MI was seen in one patient in the combination group (p<0.001) & two patients in the ic Abciximab group. There was no cardiovascular mortality noted in the present study (p<0.001). Conclusion: Intracoronary Abciximab + manual thrombus aspiration reduces thrombus burden with better results in microvascular perfusion assessed by ST-segment resolution of >70% at 90 min & higher Myocardial Blush Grade compared to intracoronary Abciximab alone in patients with STEMI undergoing primary PCI.

Abstract Background Thrombus aspiration (TA) might have a potential role in STEMI patients with heavy thrombus burden. The objective of several prospective trials whether routine TA in STEMI patients, contributes to a reduced mortality. After the first promising results, mainly based on the single center (TAPAS trial), results of the largest randomized trials to date (TASTE) study and (TOTAL) study, have not shown any significant differences in all-cause mortality, re-hospitalizations or stent thrombosis after a maximum of one-year follow-up period Objectives The aim of this prospective study is to study the in-hospital & short term out-come of using manual thrombus aspiration in STEMI patients undergoing primary PCI & showing large thrombus burden. Results The study included 209 patients referred to (CCU) of (Ain Shams University hospitals) with diagnosis of STEMI, who had under-gone primary PCI, with evidence of heavy thrombus burden . All the patients received DAPT, 99% had received GPIIbIIIa antagonists. The patients were divided into 2 groups: group (A) included 73 patients, who had under-gone manual thrombus aspiration followed by PCI to culprit lesion +/- other vessels & and group (B) included 136 patients, who had under-gone primary PCI of culprit lesion+/- other vessels, using the standard technique, without thrombus aspiration, within the period from 11/2016 till 7/2018(21 months),and they were followed up during hospital stay & for one month following hospital discharge. No stents were used in 13.7% of group (A), but no stents were used on 3.7% of group (B) (p value= 0.007). TIMI III flow had been achieved in 94.5% of group (A), 80.1% of group (B)(p value = (0.020) . MBG 3 had been achieved in 82.2% of group (A), 58.1% of group (B) . ST-segment resolution &gt; 70% had been achieved in 8.2% of group (A), that hadnot been achieved in group (B) (p value =0.003). Mortality(among MACE) was the only event detected (p value 0.026). Follow up MACE were statisticalLy significant results (p value=0.022) . Statistically highly significant results regarding, LV systolic function EF %, p vaue= 0.001, had been achieved . Conclusion In STEMI patients with evidence of heavy thrombus burden, a strategy of manual aspiration thrombectomy is valuable in reducing index hospitalization mortality, and 1 month follow-up rates of mortality, TIMI flow, better MBG, ST-segment resolution, in addition to left ventricular systolic function .

Long Term Mortality

Background: Mortality benefit of routine intracoronary thrombus aspiration during primary percutaneous coronary intervention (PCI) has been questioned. The recent TASTE trial did not show a mortality benefit with thrombus aspiration at 1 month, however benefits from accompanying reductions in myocyte injury might accrue over time. A meta-analysis of randomized trials (RCTs) was performed to evaluate the effect of follow up duration on effectiveness of aspiration thrombectomy. Methods: PubMed, Cochrane Library, EMBASE, Web of Science and CINAHL databases were searched through March, 2014. We included RCTs with acute myocardial infarction (AMI) patients randomized to aspiration thrombectomy prior to primary PCI compared with conventional primary PCI alone. Two individuals reviewed the trials for inclusion and extracted data from the RCTs. We used random-effects models. Results: Data were pooled from 16 RCTs with 11,649 patients. All-cause mortality was significantly lower with aspiration thrombectomy after at least 12 months of follow up (Odds ratio [OR] =0. 61; 95% CI 0.37-0.99; p=0. 05). Pooled data for other time frames, i.e in-hospital, 1 month, 6 month follow up, did not reach statistical significance. Conclusion: Beneficial effects of thrombus aspiration on mortality are not evident until 12 months post-procedure, consistent with the long-term effects of myocardial salvage. Subsequent trials evaluating thrombus removal should accordingly be powered for long-term mortality in addition to known procedural and angiographic endpoints.

Objective: ST-segment elevation myocardial infarction (STEMI) patients with the multivessel disease have distinctive plaque characteristics in non-IRA lesions. Intensive statin therapy was a potential approach to treat STEMI patients with the non-IRA disease. However, there is still poor evidence about the therapeutic effect. In this study, we have evaluated the detailed therapeutic effect of statin plus ezetimibe intensive therapy. Method: For STEMI patients with non-IRA disease undergoing primary percutaneous coronary intervention (PCI), 183 control STEMI patients without non-IRA disease undergoing primary PCI, and 200 STEMI patients with non-IRA disease undergoing primary PCI were introduced into this study. 200 STEMI patients with non-IRA disease undergoing primary PCI were divided into Normal group, Intensive group, Normal & Combined group, and Intensive & Combined group. The baseline information for each participant was recorded. Meanwhile, the physiological and biochemical indicators of each member with different treatments were collected after one-year follow-up. Result: For STEMI patients with non-IRA disease undergoing primary PCI, no differences could be detected in multiple indexes such as OCT examination results, age, stroke, etc. However, diabetes mellitus, smoking, and coronary Gensini score were different between different groups (P<0.05). After one year follow-up, cholesterol, low-density lipoprotein, coronary Gensini score, thin-cap fibroatheroma, length of non-infarcted arterial lesions, non-infarct artery lesion range, myocardial infarction again, and revascularization again were significantly different between different groups (P<0.05). Conclusion: The results mentioned above suggested that pitavastatin combined with ezetimibe was an effective approach to STEMI patients with non-IRA disease undergoing primary PCI. The results obtained in this study have provided a novel way for the treatment of STEMI patients with non-IRA disease undergoing primary PCI.

Abstract Background Despite primary percutaneous coronary intervention (PPCI) is generally considered the best therapy in older frail adults with ST-segment elevation myocardial infarction (STEMI), the incidence of re-hospitalization for cardiovascular diseases remains significant in these patients. Aims We hypothesized that thrombus aspiration (TA) before PPCI could be a useful treatment for reducing mortality and rehospitalizations in frail patients undergoing PPCI for STEMI. Methods We conducted a study comparing PPCI alone vs TA + PPCI in frail STEMI patients. We examined a cohort of consecutive frail patients aged ≥ 65 years with first STEMI treated with PPCI between February 2008 and July 2015 at the Department of Cardiology of the “Cardarelli” Hospital in Naples, Italy. Results The study was completed by 389 patients (PPCI: 195, TA + PPCI: 194). At 1-month follow-up, the rate of death from any cause was 7.0% in patients treated with PPCI alone vs 3.0% in patients treated with TA + PPCI (p 0.036), whereas death from cardiovascular causes was 6.0% in the PPCI group vs 3.0% in the TA + PPCI group (p 0.028). Equally important, the rate of re-hospitalization due to heart failure was 7.5% in the PPCI group vs 4.0% in TA + PPCI group (p 0.025) and the rate of re-hospitalization due to acute coronary syndrome was 10.0% in the PPCI group vs 4.5% in the TA + PPCI group (p 0.016). Conclusion These results indicate the importance of TA in the treatment of STEMI in a group of high-risk patients such as elderly with frailty.

Early Restoration

Background: Facilitated percutaneous coronary intervention (PCI), in which pharmacological agents are administered before coronary angiography, may result in early restoration of myocardial perfusion and can improve clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). To examine whether facilitated PCI is associated with better myocardial perfusion and clinical outcomes than primary PCI, we performed a meta-analysis of the clinical trials that compared the two strategies. Methods: PubMed, EMBASE, and The Cochrane Collaboration databases were searched through June 2008. We included clinical trials that were published in English language peer-reviewed medical journals and randomized patients with STEMI to facilitated or primary PCI. Two investigators independently abstracted data. Random-effects model was used to pool results. Results: Of the 419 identified articles, 24 were included (total patients =7997, facilitated PCI =4409, primary PCI =3588, median age=61 years, males=78%). Facilitated PCI increased myocardial perfusion as measured by grade 2 and/or 3 myocardial blush (588 vs. 468, OR=1.66, 95%CI=1.19 to 2.32) and ST segment resolution (1021 vs. 790, OR=1.61, 95%CI=1.25 to 2.09) as compared to primary PCI. Facilitated PCI was similar to primary PCI in reducing mortality (238 vs. 215, OR=1.10, 95%CI=0.88 to 1.37), reinfarction (129 vs. 109, OR=1.16, 95%CI=1.16(0.87 to 1.55), target vessel revascularization (181 vs. 144, OR=1.34, 95%CI=0.88 to 2.04), and stroke (51 vs. 24, OR=1.99, 95%CI=0.85 to 4.66). However, facilitated PCI was associated with increased incidence of major bleeding (236 vs. 151, OR=1.42, 95%CI=1.12, 1.81). Conclusion: As compared to primary PCI, facilitated PCI is associated with early restoration of myocardial perfusion, but has no effect on overall mortality, reinfarction, target vessel revascularization, and stroke, and increases risk of major bleeding in patients with STEMI.

SummarySeveral studies have shown that suboptimal myocardial perfusion may be observed despite optimal epicardial recanalisation in patients undergoing primary angioplasty for ST-segment elevation myocardial infarction (STEMI), resulting in unfavourable outcome. The aim of the current study was to evaluate the benefits in myocardial perfusion and mortality from adjunctive tirofiban administration in patients undergoing primary angioplasty for (STEMI). A total of 1,969 patients with STEMI treated by primary angioplasty represent the population of the current study. All clinical, angiographic and follow-up data were prospectively collected. Tirofiban was administrated in 481 patients (24.4%) (all before angioplasty). Tirofiban was associated with less distal embolisation (11.7% vs 16.1%, p = 0.048), better postprocedural MBG 3 (50.9% vs 39.7%, adjusted p < 0.0001) and a significant reduction in 1-year mortality (3% vs 6.4%, adjusted p = 0.045). The benefits in mortality were confirmed in all subgroups identified according to the quartiles of the propensity score. This study shows that, when compared to control group, adjunctive tirofiban before primary angioplasty for STEMI is associated with better myocardial perfusion and a reduction in 1-year mortality.
