Abstract Background: Previous studies of childhood cancer survivors demonstrated the existence of transient or persistent left ventricular (LV) regional wall motion abnormalities (WMA) after treatment with anthracyclines, but the differential impact on deformation of persistent regional WMA against global LV myocardial performance is unknown. Methods: To investigate whether childhood cancer survivors after treatment with anthracyclines with persistent LV regional WMA have a poorer LV myocardial performance compared to those without WMA, 34 long-term childhood cancer survivors (mean age 14.6±4.0 years) with a median cumulative anthracycline dose 234.7mg/m2 (range 80-625mg/m2) who had been off treatment for ≥ 5 years and a preserved LV ejection fraction (EF) (>55%), and 12 healthy control subjects, were studied by using 3D speckle-tracking echocardiography (3D STE). The 34 patients were divided into two groups according to the existence of regional WMA: group 1 (with WMA, n=14), group 2 (without WMA, n=20). 3D STE was performed to assess LV global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), global area strain (GAS), LV torsion, LV end-diastolic volume (LVEDV), LV end-systolic volume (LVESV), LVEF, and LV systolic dyssynchrony index (SDI: % of SD of time to peak of the 16-segment/R-R interval). Results: Of the 14 patients with WMA, regional WMA was seen at mid-anterior septum in 13 patients (92.8%) and apical septum in 1 patient (7.2%). There was no statistical difference in LVEDV, LVESV, LVEF, GLS, LV torsion or SDI derived from GLS, GCS, GAS among the 3 groups. In contrast, there were significant differences in GRS (p<0.001), GAS (p<0.018), GCS (p<0.025), and SDI derived from GRS (p<0.01) among the 3 groups. Compared with group 2, group 1 had significantly reduced GRS (14.3±6.1% vs. 33.1±10.1%, p=0.003), GCS (-23.5±3.7% vs. -33.9±6.5%, p=0.026), GAS (-34.3±5.1% vs. -45.41±6.6%, p=0.034, respectively), and greater SDI derived from GRS (16.5±5.1% vs. 6.9±2.9%, p<0.01, respectively). Moreover, existence of WMA was correlated with GRS (p<0.0001), SDI derived from GRS (p<0.0001), LVEF (p=0.036), and cumulative dose (p=0.049). Multiple linear regression analysis identified GRS as a significant determinant of the existence of WMA (β=0.751, p=0.001). Conclusion: Childhood cancer survivors after anthracycline therapy with persistent regional WMA show a poorer LV myocardial performance with mechanical dyssynchrony compared to those without regional WMA, despite a preserved LVEF.

Abstract OnBehalf Stress Echo 2020 study group of the Italian Society of Cardiovascular Imaging Background ABCDE-stress echocardiography (SE) may explore different aspects in the heterogeneous entity of known or suspected heart failure (HF). Aim To assess ABCDE-vasodilator SE in non-ischemic HF Methods In a prospective, observational, multicenter study, we recruited 428 patients with angiographically normal coronary arteries: 148 patients with HF and preserved (&gt;50%) ejection fraction (HFpEF, Group 1); 100 with HF and mid-range (40-50%) ejection fraction (HFmrEF, Group 2); 180 with HF and reduced (&lt;40%) ejection fraction (HFrEF, Group 3). A group of 75 healthy asymptomatic patients (30 male, 40%, age 57 ± 14 years) referred to testing for screening was also selected (Controls). All patients underwent vasodilator SE with dipyridamole (0.84 mg/kg) in 14 accredited laboratories of 5 countries (Argentina, Brasil, Russian Federation, Serbia and Italy). The ABCDE-SE protocol was adopted: A for regional wall motion abnormalities; B for B-lines (positivity criterion: stress ≥ rest for ≥ 2 points in a 4-site simplified scan available in 181 pts and 10 controls); C for left ventricular contractile reserve (LVCR) based on force (systolic blood pressure/end-systolic volume, positivity criterion: peak/ rest ≤1.1); D for pulsed wave Doppler-based assessment of coronary flow velocity reserve (CFVR) in left anterior descending coronary artery (positivity criterion: peak/rest ≤2.0); E for EKG-based assessment of heart rate reserve (positivity criterion: peak/rest ≤1.22). Results All positivity criteria, except A, were more prevalent (p&lt;.01) in Group 3 compared to Group 2, in Group 2 compared to Group 1, and Group 1 compared to controls: see figure. In particular, a blunted heart rate reserve was found in 4/75 controls (5%), 27/148 pts of Group 1 (18%), 28/100 of Group 2 (28%) and 98/180 of Group 3 (54%). Conclusions ABCDE-vasodilator SE can help to identify the profound pathophysiological heterogeneity underlying a similar clinical presentation in patients with known or suspected HF with angiographically normal coronary arteries. These patients rarely show stress-induced regional wall motion abnormalities (A), but may exhibit pulmonary congestion (B), reduced myocardial functional reserve (C), altered coronary microcirculation (D) and cardiac autonomic dysfunction (E).

Abstract Background B-profile detected by lung ultrasound (LUS) during stress echocardiography (SE) consists in B-lines with lung sliding and mirrors extra-vascular lung water accumulation (“wet lung”), more often found with ischemic regional wall motion abnormalities (RWMA) and/or diastolic dysfunction. B-lines present at rest may also decrease during stress. Aim To assess the frequency and functional correlates of decreasing B-profile (“drying lung” pattern) during SE. Methods We prospectively performed transthoracic echocardiography (TTE) and LUS evaluation at rest and peak stress in 780 patients with B-lines at rest referred for exercise (n=387), vasodilator (n=324) or dobutamine (n=69) SE for known/suspected coronary artery disease (CAD) and/or heart failure (HF). Recruitment occurred in 17 certified labs of 8 countries with the ABCD protocol, including regional wall motion abnormalities with wall motion score index (WMSI), B-lines, left ventricular contractile reserve (LVCR based on force, systolic blood pressure/end-systolic volume) and Doppler-based coronary flow velocity reserve (CFVR, available in 473 patients). By LUS, we adopted the 4-site simplified scan, each site scored from 0=normal A-lines, to 10=coalescing B-lines. By selection, all patients had resting B-lines score ≥2. Invasive or noninvasive coronary angiography was available in 208 patients. Results Two B-lines stress patterns were identified: Group 1, increase or unchanged pattern (B-line stress score ≥ rest, n=698, 89%); Group 2, decrease-disappearance pattern (B-line stress score < rest for ≤2 points, n=82, 11%). Group 1 showed higher prevalence of inducible ischemia (Group 1 = 74/698 vs. Group 2 = 5/82, 11% vs. 6%, p<0.001), abnormal LVCR (Group 1 = 403/698 vs. Group 2 = 36/82, 58% vs. 42%, p=0.012) and impaired CFVR (Group 1 = 173/433 vs. Group 2 = 5/40, 40 vs. 12%, p<0.001): see figure. Two- or three-vessel coronary artery disease was also more frequent in fixed-worsening pattern (Group 1 = 88/191 vs. Group 2 = 3/17, 46 vs. 17%, p=0.024). Multivariate logistic regression analysis identified peak Force (Odds Ratio, OR, 1.039, 95% Confidence Intervals, CI: 1.006–1.074, P=0.022), stress-rest Δ-WMSI (OR 0.190, 95% CI 0.086–0.419, P<0.001) and normal CFVR (OR=1.754, 95% CI: 1.147–2.682, P=0.010) as significant predictors of drying lung pattern. Disappearing BLines Conclusion About one out of 10 patients with resting B-lines exhibit a decrease-disappearance pattern during stress. They show a more benign coronary anatomic, myocardial functional and coronary physiological profile compared to patients with the fixed-worsening pattern. The drying lung pattern is more often accompanied by a strong (higher peak force), non-ischemic and warm heart (with normal CFVR).

Introduction: With increasing burden of Coronary Artery Disease (CAD) and ST-Elevation Myocardial Infarction (STEMI) in India, early risk stratification of patients is as important as making a correct diagnosis. Cardiac Troponin T (cTnT), C-Reactive Protein (CRP) and echocardiographic Regional Wall Motion Abnormalities (RWMA) are used to assess the patients of STEMI at presentation. The short term prognostic importance of these parameters also need to be known. Aim: To study the prognostic values of admission Cardiac Troponin T (cTnT), CRP and echocardiographic RWMA in patients with acute STEMI. Materials and Methods: Fifty patients of STEMI were evaluated from January 2017 to July 2017 by Troponin-T (positive >0.18 ng/mL), CRP (positive >3 mg/l) and echocardiography (positive with presence of RWMA) on day one. The patients were divided into three groups: Group 1: patients with all the three parameters positive, Group 2: patients with all three parameters negative, Group 3: patients with one or two parameters positive. The end points observed were heart failure Left Ventricular Ejection Fraction (LV EF) <40%) assessed by echocardiography at day 28, significant ventricular ectopics (>class II by Lown’s classification) and mortality at day 30 in the groups. Chi-square test for equality of proportions was used to analyse the difference in outcome in the groups. Results: The mean age of patients was 54 years. There were 25 (50%) patients in group 1, 14 (28%) patients in group 2 and 11 (22%) patients in group 3. Twelve (24%) patients had heart failure with 9 (18%) in group 1 and 3 (6%) in group 3 (p<0.05). 9 (18%) patients had significant ventricular ectopics with 8 (16%) patients in group 1 and 1 (2%) patients in group 3 (p<0.05). Mortality was found in 9 (18%) patients with 8 (16%) patients in group 1 and 1 (2%) patients in group 3 (p<0.05). Conclusion: Acute STEMI with high cTnT, CRP and presence of RWMA on echocardiography at admission need more aggressive management and close follow-up.

Takotsubo cardiomyopathy is usually described following acute emotional stress. We report here the case of a 48-year-old woman admitted for acute coronary syndrome after an intensive squash match. Diagnosis of Takotsubo cardiomyopathy due to acute physical stress was suspected in presence of normal coronary arteries and transitory left ventricular dysfunction with typical apical ballooning. Cardiac magnetic resonance imaging confirmed regional wall-motion abnormalities and was helpful in excluding myocardial infarction diagnosis. During squash the body is subject to sudden and vigorous demands inducing a prolonged and severe workload on the myocardium.

While the increased rates of survival in childhood cancers have increased progressively in recent decades, many childhood cancer survivors will have at least one chronic health condition within 40 years of age. In this regard, cardiovascular complications have emerged as a leading cause of long-term morbidity and mortality in long-term survivors of childhood cancer, likely due to exposure to anthracycline chemotherapy, and outcomes in patients with anthracycline-related cardiomyopathy remain poor. Some progress has been made in understanding the mechanisms at the basis of anthracycline-related cardiomyopathy, which appear to involve generation of reactive oxygen species, leading to mitochondrial dysfunction, followed by myocyte apoptosis and maladaptive left ventricular remodeling. Even if several guidelines currently exist for monitoring cancer patients treated with cardiotoxic therapies who are at high risk for heart failure, much work remains to be done in finding reliable markers for screening for cardiac dysfunction. Studies from our group have identified alterations in L-carnitine in cancer survivors. While additional investigations are needed, preliminary studies suggest a role for carnitine in primary prevention (during treatment) and secondary prevention (to improve function after treatment).

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a syndrome with different causes, characterised by clinical evidence of myocardial infarction with normal or near-normal coronary arteries on angiography. Its prevalence ranges between 5% and 25% of all myocardial infarction. The prognosis is extremely variable, depending on the cause of MINOCA. The key principle in the management of this syndrome is to clarify the underlying individual mechanisms to achieve patient-specific treatments. Clinical history, electrocardiogram, cardiac enzymes, echocardiography, coronary angiography and left ventricular angiography represent the first level diagnostic investigations to identify the causes of MINOCA. Regional wall motion abnormalities at left ventricular angiography limited to a single epicardial coronary artery territory identify an ‘epicardial pattern’whereas regional wall motion abnormalities extended beyond a single epicardial coronary artery territory identify a ‘microvascular pattern’. The most common causes of MINOCA are represented by coronary plaque disease, coronary dissection, coronary artery spasm, coronary microvascular spasm, Takotsubo cardiomyopathy, myocarditis, coronary thromboembolism, other forms of type 2 myocardial infarction and MINOCA of uncertain aetiology. This review aims at summarising the diagnosis and management of MINOCA, according to the underlying physiopathology.
