Introduction. Data on effects of thrombus aspiration on left ventricular diastolic function in ST-elevation myocardial infarction (STEMI) population are scarce. Objective. We sought to compare echocardiographic indices of the diastolic function and outcomes in STEMI patients treated with and without manual thrombus aspiration, in an academic, high-volume percutaneous coronary intervention (PCI) center. Methods. A total of 433 consecutive patients who underwent primary PCI in 2011-2012 were enrolled in the study. Patients were not eligible for the study if they already suffered a myocardial infarction, had been previously revascularized, received thrombolytics, presented with cardiogenic shock, had significant valvular disease, atrial fibrillation or had previously implanted pacemaker. Comprehensive echocardiogram was performed within 48 hours. During follow-up patients? status was assessed by an office visit or telephone interview. Results. Patients treated with thrombus aspiration (TA+, n=216) had similar baseline characteristics as those without thrombus aspiration (TA-, n=217). Groups had similar total ischemic time (319 ? 276 vs. 333?372 min; p=0.665), but TA+ group had higher maximum values of troponin I (39.5 ? 30.5 vs. 27.6 ? 26.9 ng/ml; p<0.001). The echocardiography revealed similar left ventricular volumes and systolic function, but TA+ group had significantly higher incidence of E/e?>15, as a marker of severe diastolic dysfunction (TA+ 23.1% vs. TA- 15.2%; p=0.050). During average follow-up of 14?}5 months, major adverse cardiac/ cerebral events occurred at the similar rate (log rank p=0.867). Conclusion. Thrombus aspiration is associated with a greater incidence of severe diastolic dysfunction in unselected STEMI patients treated with primary PCI, but it doesn?t influence the incidence of major adverse cardiovascular events.

<p><strong>BACKGROUND:<em> </em></strong>There is considerable disagreement over the effects of percutaneous coronary intervention (PCI) on left ventricular diastolic function that has necessitated the investigation of diastolic indices. The present study was conducted to evaluate left ventricular diastolic function and its indices, three months after performing the PCI procedure in patients with coronary artery disease (CAD).</p> <p><strong>METHODS:<em> </em></strong>In a quasi-experimental clinical trial study (before and after), 51 patients with CAD scheduled for elective PCI were investigated provided that their Ejection Fraction (EF) was &gt; 30%. Before and three months after PCI, echocardiography was carried out to evaluate left ventricular diastolic indices including the E/Ea as the most important criteria for diagnosis of diastolic heart failure (DHF).<strong></strong></p> <p><strong>RESULTS:<em> </em></strong>Based on the E/Ea indices and after PCI, the number of patients with DHF decreased significantly: 40 patients (78.4%) before PCI versus 28 patients (54.9%) after PCI (p&lt;0.05). The Mean and Standard error of deceleration time (DT), isovolumic relaxation time (IVRT), early diastolic mitral annulus velocity; Ea (E'), E/Ea and left ventricular ejection function (LVEF) indices underwent significant changes. In addition, MVA dur/PVA dur, PVs/PVd, and E/Ea indices had changed significantly after PCI in both genders. However, no significant difference was reported for the other indices.</p> <p><strong>CONCLUSION:<em> </em></strong>The E/Ea ratio as an important criterion for diagnosis of DHF was improved after PCI. Improvement of several other diastolic indices was observed after the PCI procedure. It can be concluded that PCI can be an effective treatment modality in patients with left ventricular diastolic indices.</p>

Objective: To determine the outcome of primary percutaneous coronary intervention (PPCI) in Ibrahim Cardiac Hospital & Research Institute. Methods: Medical records of 66 consecutive patients presented in our hospital between January 2010 toJune,2011 with acute ST elevation myocardial infarction (STEMI) and were treated with primary PCI as a mode of reperfusion were reviewed. The primary end point was in hospital mortality and secondary end points were 30 day mortality, myocardial infarction, recurrent angina and congestive cardiac failure, from discharge to one month follow up. Results: The procedural success was 98.5%. One (1.5%) patient died during hospital stay .No mortality was observed in the 30 days follow up from discharge while other complications like recurrent angina and acute left ventricular failure were 1.5%. Conclusions: Our findings suggest favorable outcomes, matching the international data can be achieved in our patients with primary PCI in the management of life threatening illness like STEMI despite all the limitations. Primary PCI as a preferred method of reperfusion strategy needs to be practiced more often in our part of the world. Ibrahim Cardiac Med J 2013; 3(1&2): 10-14

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.

Background: Assessment of cardiac biomarker release has been traditionally used to estimate the size of myocardial damage after acute myocardial infarction (AMI). However, the significance of cardiac biomarkers in the setting of primary percutaneous coronary intervention (PCI) has not been systematically studied in a large patient cohort. We evaluated the usefulness of serial and single time-point measures of various cardiac biomarkers (creatine kinase (CK), CK-MB, troponin T and I) in predicting infarct size and left ventricular ejection fraction (LVEF) after primary PCI. Methods: EVOLVE (Evaluation of MCC-135 for Left Ventricular Salvage in AMI) was a randomized double-blind, placebo-controlled trial comparing the efficacy of intracellular calcium modulator as an adjunct to primary PCI in patients with first large AMI. Levels of cardiac biomarkers (CK, CK-MB mass, troponin T and I) were determined in 375 patients at baseline before PCI and 2, 4, 12, 24, 48 and 72 hours thereafter. Single photon emission computed tomography imaging was performed to measure infarct size and LVEF on day 5. Results: Area under curve and peak concentrations of all cardiac markers: CK, CK-MB mass, troponin T and troponin I were significantly correlated with myocardial infarct size and LVEF determined on day 5 (Spearman correlation, all P< 0.001; Table ). Troponin I, however provided the best predictor and a single measure at 72 hr was a strong indicator of both infarct size and LVEF. Using receiver operator characteristics curve, troponin I cutoff value of >55 pg/mL at 72 hr has 90% sensitivity and 70% specificity for detection of large infarct size≥10% ( c =0.88; P< 0.001). Conclusions: Plasma levels of CK, CK-MB, troponin T and troponin I remain useful predictors of infarct size and cardiac function in the era of primary PCI for AMI. A single measurement of circulating troponin I at 72 hours can provide an effective and convenient indicator of infarct size and LVEF in clinical practice. Correlation of cardiac biomarkers with Day 5 SPECT determined infarct size and LVEF
