Introduction: Left ventricular apical ballooning (AB) mimics anterior myocardial infarction (AMI). This study assessed if the ECG can differentiate between these two syndromes with a similar clinical presentation. Methods: Among 2086 patients (pts) with an ACS, 33 (1.6%) with AB were identified (29 f, 4 m, median age 77 years) and compared to 28 consecutive age and sex matched AMI pts undergoing PCI of the LAD with similar findings on LV angiography. Results: AB pts arrived at the hospital later after symptom onset (median 21 vs 5 hours; p<0.001). On the admission ECG, the number of leads with ST-segment elevation (4 [3-6] vs 5 [5-7], p=0.005) and the magnitude of ST-segment elevation (0.7 [0.5-0.9] vs 0.9 [0.7-1.5] mV, p=0.002) were greater in AMI. Reciprocal ST-segment depression was similar (27% vs 54%, p=ns). A positive T wave in aVR was more frequent in AB (49% vs 7%, p<0.001). During follow-up, AB pts had more leads with T-wave inversion (8 [8-9] vs 6 [5-8], p<0.001) and a larger magnitude of T-wave inversion (2.9 [2.2-4.6] vs 1.4 [0.9-2.3] mV, p<0.001). T-wave inversion was similar in I, aVL and V2-V5. AB pts, however, showed negative T-waves also in lead II (74% vs 22%, p<0.001), III (34% vs 4%, p=0.004), aVF (51% vs 11%, p=0.001) and a positive T wave in aVR (100% vs 70%, p=0.005). The QTc interval was longer in AB (515 [482-543] vs 458 [435-484] ms, p<0.001). An abnormal Q wave on admission was more frequent in AMI (21% vs 79%, p<0.001) and persisted but was absent in AB at discharge (0% vs 61%, p<0.001). Ventricular tachycardia was similar (2% vs 14%, p=ns) but atrial fibrillation occurred only in AB (21% vs 0%, p=0.013). The ECG normalized in all AB but in only 1 AMI pt (p<0.001). Overall, despite a similar ejection fraction (54±15 vs 55±13 %) and lower troponin I values (7.5±6.9 vs 238±221 ng/ml, p<0.001), AB pts developed significantly more adverse events compared to AMI pts (52% vs 18%, p<0.008). Conclusion: ECG patterns in AB are significantly different from those in AMI. On admission, the extent of ST-segment elevation and the number of Q waves are greater in AMI. During follow-up, no Q wave, a longer QTc interval, a greater extent of T-wave inversion and a positive T wave in aVR are typical findings in AB. Adverse events are more frequent in AB than in AMI.

Background Electrocardiogram (ECG) manifestations of takotsubo cardiomyopathy (TC) produce ST-segment elevation or T-wave inversion, mimicking acute coronary syndrome (ACS). We describe the ECG manifestation of TC, including ECG evolution, and its different points from ACS. Methods We studied 37 consecutive patients (age 67 ± 15 years, range 23-89, M:F = 12:25) from March 2004 to November 2012 with a diagnosis of TC who were proven to have apical ballooning on echocardiography or left ventricular angiography and normal coronary artery. We analyzed their standard 12-lead ECGs, including rate, PR interval, QRS duration, corrected QT (QTc) interval, ECG evolutions, and arrhythmia events. Results Two common ECG findings in TC were ST-segment elevation (n = 13, 35%) and T inversion (n = 24, 65%), mostly in the precordial leads. After ST-segment resolution, in a few days (3.5 days), diffuse and often deep T-wave inversion developed. Eight patients (22%) had transient Q-waves lasting a few days in precordial leads. No reciprocal ST-segment depression was noted. T-wave inversion continued for several months. QT prolongation (>440 milliseconds) was observed in 37 patients (97%). There were no significant life-threatening arrhythmias except atrial fibrillation (n = 6, 16%). Conclusion There are distinct differences between the ECGs of TC and ACS. These differences will help to differentiate TC from ACS.

Background : The German tako-tsubo cardiomyopathy (TTC) registry has been initiated to further evaluate this syndrome in a western population. We aimed to assess different patterns of left ventricular involvement in TTC. Methods : Inclusion criteria were: 1) acute chest symptoms, 2) reversible ECG changes (ST-segment elevation±T-wave inversion), 3) reversible left ventricular dysfunction with a wall motion abnormality not corresponding to a single coronary artery territory, 4) no significant coronary artery stenoses. Results : A total of 258 patients (pts) from 33 centers were included with a mean age of 68±12 years. Left ventriculography revealed the typical pattern of apical ballooning in 170 pts (66%) and an atypical mid-ventricular ballooning with normal wall motion of the apical and basal segments in 88 pts (34%). Mean age (68±11 vs 67±13 years) and gender distribution (150 women/20 men vs 80 women/8 men) were similar in both groups. Triggering events were present in 78% of the pts with apical ballooning (35% emotional, 34 physical and 9% combination) and in 75% of the pts with mid-ventricular ballooning (39% emotional, 25% physical and 11% combination). As assessed by left ventriculography, ejection fraction was significantly lower in pts with mid-ventricular ballooning (50±15% vs 45±13%, p=0.006). There was no difference in right ventricular involvement. Creatine kinase and troponin I were comparable in both groups. The ECG on admission showed ST-segment elevation in 87% of pts with apical ballooning and in 78% of pts with mid-ventricular ballooning. T-wave inversion was seen in 70% of the pts irrespective of the TTC variant. A Q-wave was significantly less present in pts with mid-ventricular ballooning (30% vs 16%, p=0.04). The QTc interval during the first 3 days was not different among both groups. Conclusion : A variant form with mid-ventricular ballooning was observed in one third of the pts with TTC. Left ventricular ejection fraction was significantly lower in these pts, although they revealed significantly less Q-waves on the admission ECG. All other parameters were similar and confirm the concept that apical and mid-ventricular ballooning represent two different manifestations of the same syndrome.

Introduction. Rapid diagnosis of acute myocardial infarction is essential for proper treatment and reduction of patient mortality. Electrocardiography plays an important role in its diagnosis. Acute myocardial infarction with ST segment elevation requires urgent reperfusion therapy, that is, primary percutaneous coronary revascularization. A small number of patients with acute myocardial infarction have ST segment depression in one or more leads, whereas ST segment elevation in augmented vector right the electrocardiogram is characteristic for a myocardial infarction without ST elevation, but the clinical course and the severity of disease correspond to the anterior myocardial infarction with ST segment elevation. De Winter T-wave electrocardiography. One of these forms is known as de Winter T-wave pattern, characterized by ST segment depression at the J-point (> 1 mm) in the precordial leads, the absence of ST segment elevation in the precordial leads, high peaked and symmetrical T-waves in the precordial leads and, in most cases, mild ST segment elevation (0.5 mm to 1 mm) in the augmented vector right. These patients have occlusion of the left main coronary artery, occlusion of the proximal segment of the anterior descending artery, or a severe multivessel coronary disease. Patients with this electrocardiographic pattern, which is equivalent to acute myocardial infarction with ST segment elevation, require consideration of emergency reperfusion therapy due to high mortality, compared to other patients with acute myocardial infarction without ST elevation. Primary percutaneous intervention is recommended, or if there is no catheterization laboratory nearby, fibrinolytic therapy may be considered. Because of the lack of clear recommendations, treatment decisions are made individually, from case to case. Conclusion. We need large pro?spective studies with this specific electrocardiographic pattern to provide quick recognition and proper treatment of the anterior myocardial infarction with ST elevation.

Main funding source(s): Wellcome Trust Background Sudden cardiac death (SCD) occurs in both acute and chronic stages post myocardial infarction (MI), and the left ventricular ejection fraction (LVEF) and electrocardiogram (ECG) characteristics are important biomarkers for clinical decision making. While various ionic remodelling has been reported in literature at various stages post-MI, the effect of them on clinical biomarkers have not been fully explored. Purpose Evaluate the effects of cellular ionic remodelling in acute and chronic post myocardial infarction on ECG and LVEF biomarkers through computational modelling and simulations of human biventricular electromechanics. Methods An electromechanical coupled biventricular model with ToR-ORd (Tomek 2019) human electrophysiology coupled with human excitation-contraction machinery (Land 2017) and orthotropic passive mechanics (Holzapfel 2009) was used as baseline model. The 12-lead ECG were simulated at standard body-surface electrode locations, and the biventricular pressure volume loop was simulated to quantify the simulated LVEF. A cardiac magnetic resonance (CMR) derived human biventricular geometry (Strocchi 2020) was used in combination with rigidly aligned torso geometry (Minchole 2019). An anterior sub-endocardial infarction was delineated with infarct, border zone (BZ) and remote zone (RZ) regions. For acute infarction, three types of BZ ionic remodelling from literature, and their effects on simulated LVEF and ECG characteristics were quantified. For chronic infarction, a single chronic BZ ionic remodelling was combine with two different models of RZ ionic remodelling from literature, and the effects of these remodelling on the simulated LVEF and ECG were quantified. The electromechanical properties of the sub-endocardial infarct region did not significantly affect simulated ECG or LVEF biomarkers. Results For the acute phase, simulations showed pre-cordial ECG abnormalities for all three BZ models, with T-wave inversion and QT prolongation (80 ms) in BZ1, ST-segment elevation with T-wave inversion in BZ2, and decreased T-wave amplitude in BZ3. Activation maps showed conduction block in BZ2 simulations, leading to ST-segment elevation. Repolarisation maps showed high dispersion in BZ1 simulations, leading to T-wave inversion. LVEF for BZ2 decreased by 4% (from 57% in control) due to conduction block in BZ and lack of contraction in that region, LVEF remained constant for BZ1 and BZ3 simulations. For the chronic phase, there was QT prolongation in both RZ1 (80 ms) and RZ2 (170 ms) as well as decreased T-wave amplitude, reflected by elevated repolarisation dispersion. LVEF was not significantly altered for either simulations. Conclusions Post-MI ionic remodelling at the acute and chronic stages cause varying degrees of dispersion of repolarisation and T-wave and ST-segment abnormalities, with minimal effect on mechanical function, except in the case of severe conduction abnormality.

Abstract Introduction Bioresorbable vascular scaffolds (BVS) use appears theoretically attractive in patients presenting with ST-segment elevation myocardial infarction (STEMI) as acute lesions are generally composed of soft plaques, in which optimal BVS deployment and expansion is easier to achieve. Furthermore, those patients are generally younger and would benefit longer from the promise of vascular restoration therapy. Purpose In this patient level pooled analysis of two clinical trials, we evaluated the clinical outcomes of Absorb BVS versus Xience everolimus-eluting stent (EES) in STEMI patients at 2-year follow-up. Methods We performed an individual patient-level pooled analysis of the AIDA and COMPARE-ABSORB trials in which 3515 patient were randomly assigned to Absorb BVS (n=1772) or Xience EES (n=1743). Clinical outcomes in STEMI patients were analyzed by randomized treatment assignment cumulative through 2 years. The primary efficacy outcomes measure was target lesion failure (cardiac death, target-vessel myocardial infarction or target lesion revascularization), and the primary safety outcome measure was device thrombosis at 2-year follow-up. Results 350 (19.8%) STEMI patients were allocated to Absorb BVS versus 328 (18.8%) to Xience EES. The mean age of patient presenting with STEMI was 60 years old, 76.0% were males and 15.3% had diabetes mellitus. At 2-years target lesion failure occurred in 8.4% of BVS STEMI patients and 6.2% of EES STEMI patients (p=0.253). The 2-year rates of cardiac death (2.6% vs 1.6%, p=0.332), TV-MI (4.7% vs 2.5%) and TLR (6.8% vs 4.1%) were not significantly different. The 2-year incidence of definite device thrombosis was 4.7% in Absorb BVS versus 1.8% in Xience EES (p=0.045). Conclusion In the present patient-level pooled analysis of the AIDA and COMPARE-Absorb trials, BVS was associated with increased rates of device thrombosis in STEMI patients compared to Xience EES.
