Background. Circulating levels of cardiac troponin I (cTnI) after ST-segment elevation myocardial infarction (STEMI) were considered as prognostic factors for predicting the incidence of major adverse cardiovascular events (MACE). △cTnI is the difference between peak cTnI after primary percutaneous coronary intervention (PPCI) and cTnI on initial admission. Purpose. This study aimed to assess the relationship between △cTnI, the ratio of △cTnI to cTnI on initial admission, and the incidence of MACE during the follow-up period. Methods. A total of 2596 patients with cTnI measured upon admission and one-time measurement of cTnI during hospitalization were enrolled. Results. In the adjusted models of the survival receiver operating characteristic (ROC) curve, △cTnI and the ratio of △cTnI to cTnI on initial admission have stronger discrimination power of MACE (area under curve (AUC) 0.730 and 0.717) compared with peak cTnI after PPCI and cTnI at admission (AUC 0.590, 0.546). Multivariate Cox regression analysis identified △cTnI (hazard ratio (HR) 1.018, 95% confidence interval (CI) 1.001 to 1.035) as a relevant factor for MACE during follow-up. △cTnI was divided into quartiles, and maximum △ cTnI between 4.845 and 19.073 ng/ml comprised more patients with anterior wall myocardial infarction (p < 0.001), higher GRACE score (p = 0.038), CK-MB (p = 0.023), and Myoglobin (p < 0.001). On the K–M survival curves, the incidence of MACE, mortality, and angina pectoris were significantly higher in the group with maximum △cTnI (p = 0.035, 0.049, 0.026). Conclusion. The △cTnI level and the ratio of △cTnI have stronger discrimination power of predicting the incidence of MACE. The group with maximum △cTnI has higher incidence of MACE, mortality, and angina pectoris during the follow-up period.

Introduction. The outcome of patients with ST-elevation myocardial infarction (STEMI) strongly depends on a successful reperfusion. In some patients receiving an effective treatment myocardial infarction can be aborted.Aim. The aim of the study was to estimate the incidence, clinical outcome, prognosis and inflammatory response in patients with aborted MI.Material and methods. 119 consecutive patients with STEMI treated with a primary percutaneous coronary intervention (pPCI) were enrolled in the study. Aborted MI was diagnosed when the maximal increase in cardiac enzymes (CK-MB) was up to twice the upper limit of normal (CK-MB ? 50 U/I) and at least 50% reduction of ST-segment deviation was observed within 90 min of pPCI.Results. Aborted MI was diagnosed in 16 subjects (13.4%). Patients with the aborted MI had lower serum troponin I levels (p < 0.0001). The time to treatment was significantly shorter in the aborted MI group (101 min vs. 220 min, p < 0.00001). Patients with aborted MI had a lower corrected TIMI frame count (p < 0.05) and a lower wall motion score index (p < 0.005), less pronounced inflammatory response (lower serum levels of IL-6, p < 0.01, and MCP-1, p < 0.05), higher ejection fraction six months after MI (72% vs. 64%, p < 0.05). None of the aborted MI patients died during the 3-year follow-up, while there were 13 deaths among patients with non-aborted MI.Conclusions. The abortion of myocardial infarction results in a better outcome and more favorable prognosis. An inflammatory response is less pronounced in the aborted MI.

Background: Recent animal studies have suggested that mitral valve (MV) leaflet remodeling can occur even without significant tethering force and that the postinfarct biological reaction would contribute to the histopathologic changes of the leaflet. We serially evaluated the MV remodeling in patients with anterior and inferior acute myocardial infarction (MI), by using 2- and 3-dimensional transthoracic echocardiography. Additional histopathologic examinations were performed to assess the leaflet pathology. Methods: Sixty consecutive first-onset acute MI (anterior MI, n=30; inferior MI, n=30) patients who underwent successful primary percutaneous coronary intervention were examined (1) before primary percutaneous coronary intervention, (2) at 6-month follow-up, and (3) at follow-up 1 year or later after onset. MV complex geometry including MV leaflet area and thickness was analyzed using dedicated software. Additional histopathologic study compared 18 valves harvested during surgery for ischemic mitral regurgitation (MR). Results: MV area and thickness incrementally increased during the follow-up period. MV leaflet area significantly increased (anterior MI: 5.59 [5.28–5.98] to 6.54 [6.20–7.26] cm 2 /m 2 , P <0.001; inferior MI: 5.60 [4.76–6.08] to 6.32 [5.90–6.90] cm 2 /m 2 , P <0.001), and leaflet thickness also increased (anterior MI: 1.09 [0.92–1.24] to 1.45 [1.28–1.60] mm/m 2 , P <0.001; inferior MI: 1.15 [1.03–1.25] to 1.44 [1.27–1.59] mm/m 2 , P <0.001); data represent onset versus ≥1 year. Larger annuls, larger tenting, and a reduced leaflet area/annular ratio with smaller coaptation index were observed in patients with persistent ischemic MR compared with those without significant ischemic MR. Histopathologic examinations revealed that MV thickness was significantly greater in chronic ischemic MR compared with acute ischemic MR (1432.6±490.5 versus 628.7±278.7 μm; P =0.001), with increased smooth muscle cells and fibrotic materials. Conclusions: MV leaflet remodeling progressed both in area and thickness after MI. This is the first clinical study to record the longitudinal course of MV leaflet remodeling by serial echocardiography.

Abstract Background To investigate the relationship between the clinical features and progression of non-culprit lesions in patients with ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PPCI). Methods A total of 480 patients (57.1 ± 9.2 y) with STEMI who underwent PPCI between January 2016 and December 2017 in Beijing Anzhen Hospital were enrolled in this study. All patients underwent PPCI as a treatment for culprit lesions. Clinical and angiographic follow-up were performed for 12 months. All patients were divided into a non-culprit lesions (NCL) progression group (205 cases) and a control group (275 cases) based on angiographic follow-up outcomes at 12 months. The clinical and angiographic features were analyzed. Results Body mass index (BMI), serum creatinine (Scr), fasting blood glucose (FBG), glycated serum albumin, glycated hemoglobin and homocysteine levels in the NCL progression group were significantly higher than those in the control group (P < 0.05). A logistic regression analysis showed that FBG (odds ratio = 1.274, 95% confidence interval: 1.077–1.505, P = 0.005) and Scr (odds ratio = 1.020, 95% confidence interval: 1.002–1.038, P = 0.027) were independent predictors of NCL progression. A partial correlation analysis showed that FBG was positively correlated with NCL progression (r = 0.231, P = 0.001). A receiver operating characteristic curve showed that the boundary point of FBG to predict NCL progression was 5.715 mmol/L, and the sensitivity was 74.4% and the specificity was 46.4%. Conclusions FBG is a valuable predictor for NCL progression in patients with STEMI after PPCI.

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: The randomized DAPA trial (Defibrillator After Primary Angioplasty) aimed to evaluate the survival benefit of prophylactic implantable cardioverter defibrillator (ICD) implantation in early selected high-risk patients after primary percutaneous coronary intervention for ST-segment–elevation myocardial infarction. Methods: A randomized, multicenter, controlled trial compared ICD versus conventional medical therapy in high-risk patients with primary percutaneous coronary intervention, based on one of the following factors: left ventricular ejection fraction <30% within 4 days after ST-segment–elevation myocardial infarction, primary ventricular fibrillation, Killip class ≥2 or TIMI (Thrombolysis in Myocardial Infarction) flow <3 after percutaneous coronary intervention. ICD was implanted 30 to 60 days after MI. Primary end point was all-cause mortality at 3 years follow-up. The trial prematurely ended after inclusion of 266 patients (38% of the calculated sample size). Additional survival assessment was performed in February 2019 for the primary end point. Results: A total of 266 patients, 78.2% males, with a mean age of 60.8±11.3 years, were enrolled. One hundred thirty-one patients were randomized to the ICD arm and 135 patients to the control arm. All-cause mortality was significant lower in the ICD group (5% versus 13%, hazard ratio, 0.37 [95% CI, 0.15–0.95]) after 3 years follow-up. Appropriate ICD therapy occurred in 9 patients at 3 years follow-up (5 within the first 8 months after implantation). After a median long-term follow-up of 9 years (interquartile range, 3–11), total mortality (18% versus 38%; hazard ratio, 0.58 [95% CI, 0.37–0.91]), and cardiac mortality (hazard ratio, 0.52 [95% CI, 0.28–0.99]) was significant lower in the ICD group. Noncardiac death was not significantly different between groups. Left ventricular ejection fraction increased ≥10% in 46.5% of the patients during follow-up, and the extent of improvement was similar in both study groups. Conclusions: In this prematurely terminated and thus underpowered randomized trial, early prophylactic ICD implantation demonstrated lower total and cardiac mortality in patients with high-risk ST-segment–elevation myocardial infarction treated with primary percutaneous coronary intervention.
