Abstract

International audience; Background: A reduction of admission for MI has been reported in most countries affected by COVID-19. No clear explanation has been provided.Methods: To report the incidence of myocardial infarction (MI) admission during COVID-19 pandemic and in particular during national lockdown in two unequally affected French provinces (10-million inhabitants) with a different media strategy, and to describe the magnitude of MI incidence changes relative to the incidence of COVID-19-related deaths. A longitudinal study to collect all MIs from January 1 until May 17, 2020 (study period) and from the identical time period in 2019 (control period) was conducted in all centers with PCI-facilities in northern "Hauts-de-France" province and western "Pays-de-la-Loire" Province. The incidence of COVID-19 fatalities was also collected.Findings: In "Hauts-de-France", during lockdown (March 18-May 10), 1500 COVID-19-related deaths were observed. A 23% decrease in MI-IR (IRR=0.77;95%CI:0.71-0.84, p

Abstract

We present a case which developed a typical tako-tsubo-like cardiomyopathy (TTC) during dobutamine stress echocardiography (DSE). Its originality is related to several findings, which have never been described simultaneously in the same patient. This 63-year-old woman with normal coronary angiography and no evidence of coronary vasospasm had a biphasic response to DSE, a finding which usually occurs in coronary artery disease. Moreover, the symmetric extensive wall motion abnormalities (WMA) occurred simultaneously with the development of a systolic anterior motion of the mitral valve (SAM) and left ventricular obstruction, and was clinically asymptomatic. Although in TTC the stunning usually occurs for several days, WMA and SAM resolved within few minutes after cessation of dobutamine and administration of a beta-blocker. And finally, exercise echo performed at the same target heart rate few days later did not induce neither a SAM nor WMA, which suggests that left ventricular obstruction could have played a role in the pathogenesis of this case by supply-demand mismatch. Concomitant coronary microvascular dysfunction was also demonstrated by a reduction of the non-invasive coronary flow reserve in the distal part of the left anterior descending artery.

Abstract

Paradoxical embolism is rarely demonstrated, often suggested, and the diagnosis has been largely presumptive in most cases. The patent foramen ovale (PFO) is an important predisposing anatomic factor for such a complication. We describe a case where a voluminous thrombus straddling the PFO was diagnosed by echocardiography including the 3D modality, in the setting of acute massive pulmonary embolism. The treatment is not codified in this setting, and the thrombus was successfully removed by surgery, associated with PFO closure, and anticoagulation.

Abstract

To test the usefulness of non-invasive coronary flow reserve (CFR) by transthoracic Doppler echocardiography by comparison to invasive fractional flow reserve (FFR) and instantaneous wave-free ratio (IFR), a new vasodilator-free index of coronary stenosis severity, in patients with left anterior descending artery (LAD) stenosis of intermediate severity (IS) and stable coronary artery disease. 94 consecutive patients (mean age 68 ± 10 years) with angiographic LAD stenosis of IS (50–70 % diameter stenosis), were prospectively studied. IFR was calculated as a trans-lesion pressure ratio during the wave-free period in diastole; FFR as distal pressure divided by mean aortic pressure during maximal hyperemia (using 180 μg intracoronary adenosine); and CFR as hyperemic peak LAD flow velocity divided by baseline flow velocity using intravenous adenosine (140 μg/kg/min over 2 min). The mean values of IFR, FFR, and CFR were 0.88 ± 0.07, 0.81 ± 0.09, and 2.4 ± 0.6 respectively. A significant correlation was found between CFR and FFR (r = 0. 68), FFR and IFR (r = 0.6), and between CFR and IFR (r = 0.5) (all, p

Abstract

Aims Typical tako-tsubo cardiomyopathy (TTC) mimics acute anterior myocardial infarction (AMI) and the differential diagnosis is challenging before coronary angiography (CA) is performed; it demonstrates reduced or absent antegrade flow in the left anterior descending artery (LAD) in AMI, whereas there is no such flow limiting in TTC. At the acute phase, we tested the usefulness of the distal LAD flow visualization by transthoracic Doppler echocardiography (TDE) to distinguish between these two diseases. For this purpose, we prospectively enrolled 28 consecutive patients with TTC (75 ± 10 years, 93% females) who were compared with 28 consecutive patients with AMI treated successfully by primary angioplasty (66 ± 12 years, 79% females). All the patients underwent the assessment of the distal LAD flow just before CA, using colour and pulsed-wave TDE. In addition, the symmetric involvement of wall motion abnormalities (WMAs) based on the extent of the disease far beyond one coronary territory in TTC was searched by TDE. Non-invasive coronary flow reserve (CFR) by TDE, in the distal LAD, was also performed within 1 day after admission. Results Before CA, the distal LAD flow was visible in 38 of 56 cases (68%) in the whole population, in all cases with TTC and in 10 cases with AMI (36%). The sensitivity (Se) and specificity (Sp) of the LAD flow visualization for the diagnosis of TTC were 100 and 64%, respectively, with a diagnostic accuracy of 82%. In comparison, the pattern of WMA yielded a Se of 75% and Sp of 86%, and a diagnostic accuracy of 80%. With the combination of both tools, the Se and Sp to detect TTC were 75 and 96% respectively, with a diagnostic accuracy of 86%. After CA, the acute CFR was less severely impaired in the TTC group when compared with the AMI group (2.2 ± 0.5 vs. 1.7 ± 0.6, P < 0.01) despite a worse LV systolic dysfunction. Conclusion Non-invasive evaluation of the distal LAD flow could be helpful to differentiate TTC from AMI, and its combination with the pattern of WMA improved slightly its diagnostic accuracy. Furthermore, the acute CFR is less severely impaired in TTC compared with AMI despite poorer LV systolic dysfunction, suggesting that other mechanisms than direct microcirculatory damage are also involved in the pathogenesis of WMAs in TTC.

Abstract

Aims To assess the usefulness of non-invasive coronary flow reserve (CFR) to predict left ventricular adverse remodelling (LVR) after ST-elevation myocardial infarction (STEMI). Methods and results Sixty-five consecutive patients (mean age 58 ± 13 years, 24 women) with a first anterior STEMI, underwent prospectively CFR in the distal part of the left anterior descending artery (LAD), using intravenous adenosine infusion (0.14 mg/kg/min, within 2 min), and a standard echocardiography during the same exam, performed within 24 h after successful primary coronary angioplasty, and 6 months later, while the patients were in stable haemodynamic situation. CFR was defined as the peak hyperaemic LAD flow velocity divided by the baseline flow velocity. LV end-systolic volume (ESV) and end-diastolic volume (EDV), and LV ejection fraction (LVEF) were measured using the biplane Simpson's rule. LVR was defined as an absolute increase of ESV ≥15%. Compared with patients without LVR, patients with LVR ( n = 18) had higher peak troponin T levels, wall motion score (WMS), a worse initial angiographic TIMI flow grade, and less improved electrocardiographic ST-segment resolution (all P < 0.05), and lower CFR (1.43 ± 0.2 vs. 1.97 ± 0.5, P < 0.01). At 6 months, patients with LVR had higher WMS, ESV, EDV, and lower LVEF compared with patients without LVR (all P < 0.01). Furthermore, acute CFR was significantly correlated to the 6-month LVEF and ESV, and to change of LVEF and ESV (all P < 0.01). In the multivariate analysis, acute CFR and initial angiographic TIMI flow grade were the independent predictors of LVR (all P ≤ 0.01). Receiver-operating characteristic curve analysis demonstrated that a cut-off value of 1.7 for CFR yields a sensitivity of 100% and a specificity of 62% to predict LVR at follow-up ( P < 0.001, area under the curve 0.82). Conclusion Non-invasive CFR is an independent predictor of LVR after successful primary angioplasty of anterior STEMI.

Abstract

Aims Prognostic value of transthoracic coronary flow reserve (T-CFR) is not established in patients with left anterior descending artery (LAD) stenosis of intermediate severity. Objective is to determine the prognosis value of T-CFR > 2 in medically treated patients with angiographically intermediate [50–70% QCA (quantitative coronary angiography)] proximal LAD stenosis. Methods and results Among 110 consecutive patients with intermediate LAD stenosis who underwent prospectively T-CFR in the distal part of the LAD after intravenous administration of adenosine to assess the functional significance of the stenosis, 80 patients had T-CFR > 2 and were treated medically without revascularization (Group 1). Among the 30 patients who had T-CFR < 2, an additional dobutamine stress echocardiography (DSE) was performed: 15 had a negative DSE; were treated medically and served as a comparative group (Group 2), and 15 had a positive DSE; underwent LAD revascularization, and were excluded from further analysis. All patients completed follow-up (16 ± 10 months). During the follow-up period (range 6–45 months), 76 patients (95%) remained free of death or LAD-related event in Group 1, vs. 12 patients (80%) in Group 2. By Kaplan–Meier method, at 30 months the per cent estimated survival free from death or target vessel-related events was 92 ± 4% in Group 1 and 44 ± 22% in Group 2 ( P < 0.01). By multivariate analysis, T-CFR remained the only independent predictor of death or LAD-related events. Conclusion In patients with proximal LAD stenosis of intermediate severity and T-CFR > 2, deferral of revascularization is associated with low event rate.

Abstract

The clinical features of tako-tsubo cardiomyopathy or transient left apical ballooning syndrome (LABS) have been clearly described, but the mechanisms are still unknown. Our objective was to prospectively assess coronary microcirculation at the acute phase of LABS and after functional recovery, using Doppler transthoracic echocardiography-coronary flow reserve (CFR). Twelve consecutive patients (11 women, mean age 68 +/- 10 years) satisfying the criteria for LABS underwent Doppler transthoracic echocardiography-CFR in the distal part of the left anterior descending coronary artery, using intravenous adenosine infusion (0.14 mg/kg/min over 2 minutes) at the acute phase and 25 +/- 3 days later. CFR was calculated as the ratio of hyperemic to basal mean diastolic flow velocity. Wall-motion score (WMS) was calculated using the 16-segment model during the same echocardiographic examination (normal WMS = 16). Doppler transthoracic echocardiography-CFR increased between the two examinations from 2.2 +/- 0.4 at the acute phase to 2.9 +/- 0.3 (P.01), whereas WMS decreased (from 31 +/- 6 at the acute phase to 16.5 +/- 0.8, delta WMS = -14.6 +/- 6, P.01). All patients exhibited an increase of CFR between the two tests (delta CFR = 0.73 +/- 0.39, range: 0.3-1.6). A significant correlation was observed between delta CFR and delta WMS (r = -0.89, P.01). In conclusion, serial noninvasive CFR measurements performed in LABS suggested transient microcirculatory impairment during the acute phase of the syndrome. The wall-motion improvement parallel to the dynamic improvement of the microcirculation suggests a role of coronary microcirculatory damage in the pathogenesis of acute and transient wall-motion abnormalities in LABS.

Abstract

IntroductionAssessment of the functional significance of left anterior descending coronary artery (LAD) stenosis of intermediate severity (IS) is challenging. A direct comparison of fractional flow reserve (FFR), instantaneous wave-free ratio (IFR), and non-invasive coronary flow reserve (CFR) has never been performed. Our objective was to test the usefulness of noninvasive CFR by comparison to invasive FFR and IFR in patients with LAD stenosis of angiographic IS and stable coronary artery disease.Methods58 stable consecutive patients (mean age, 68±10 years; with angiographic proximal or mid LAD stenosis of IS (40-70% diameter stenosis on quantitative coronary angiography), no previous anterior myocardial infarction, were prospectively studied. They underwent iFR which was calculated as a trans-lesion pressure ratio during a specific period of baseline diastole, FFR with intracoronary bolus adenosine (150μg), and CFR using intravenous adenosine (140μg/kg/min over 2min) in the distal part of the LAD, the same day. CFR was defined as hyperemic peak diastolic LAD flow velocity divided by baseline flow velocity, and FFR was defined as distal pressure divided by mean aortic pressure during maximal hyperemia.ResultsThe mean values of iFR, FFR, and CFR were 0.88±0.07, 0.81±0.08, and 2.4±0.6 respectively. A significant correlation was found between CFR and FFR (r=0.72, curvilinear relationship), FFR and IFR (r=0.63, linear relationship), and between CFR and IFR (r=0.44) (all, p

Abstract

Objectiveto test the usefulness of two-dimensional longitudinal strain pattern (2DS) in segments with wall motion abnormalities (WMA) to predict left ventricular (LV) recovery and in-hospital cardiac events (CE) after acute anterior myocardial infarction (AMI).Methods45 consecutive patients (mean age 60±14 years, 40% women) with first AMI treated successfully by primary percutaneous coronary angioplasty underwent prospectively a transthoracic Doppler-echocardiography, 24hours after angioplasty, and during follow-up (3-6 months), including 2DS analysis: duration of systolic lengthening expressed as percentage of systolic duration (SL), lengthening to shortening ratio (L/S), and post-systolic shortening index (PSSi) in segments with WMA using a 18 segment model, as well as global longitudinal strain (GLS) and left anterior descending artery territory strain (LAD-S). At follow-up, recovery was defined at segmental level by normalization of WMA, at patient level by improvement of LVEF ≥10%. CE (n=14) were defined as a composite of death, reinfarction, heart failure, LV apical thrombus.Results330 of the 778 segments analyzable had WMA at the acute phase (mean 7.8±1.2 per patient), 153 recovered and 177 did not. At segmental level, SL, L/S, PSSi were correlated to recovery, whereas in multivariate analysis, only SL independently predicted recovery (threshold level 40%, sensitivity 79%, specificity 68%, p < 0. 01, AUC 0.75). At patient level, in univariate analysis, WMSI, LVEF, SL, GLS, LAD-S, and troponin peak were correlated to recovery and to CE. In multivariate analysis, SL was independently related to recovery (≤ 3 segments with SL >40%, Se = 78%, Sp=78%, p< 0.001, AUC 0.83), and to CE (with LAD-S) (all, p < 0.05).ConclusionsIn patients with AMI treated by primary angioplasty, 2DS predict viability as well as CE independently of more traditional parameters.

Abstract

Background Left atrial (LA) enlargement is associated with a poorer prognosis in several diseases, including aortic stenosis (AS). However, apart diastolic dysfunction, the main determinants of LA size in the setting of aortic stenosis are poorly understood. Objective to assess the factors correlated with LA size in patients with severe AS (aortic valve area (AVA) 2 or 2 /m 2 ) with preserved left ventricular ejection fraction (LVEF >50%). Methods 80 consecutive patients with isolated severe AS in sinus rhythm (mean age 72±10 years, AVA 0.8±0.2cm 2 , 0.44±0.1cm 2 /m 2 , mean gradient 45±15mmHg, LVEF 68±10%) underwent a comprehensive transthoracic Doppler echocardiography including the measurement of the LA volume at end-systole by the biplane area-length method (from the 4-and 2-apical chamber views), indexed to body surface area (ml/m 2 ), LVEF by the biplane Simpson’s method, LV mas by the ASE M-mode method, and early (e’), late diastolic (a’), and systolic (Sa) mitral annular Doppler tissue velocities were calculated as an average of the septal and lateral values. Results The mean LA volume was 33±12mL/m 2 (extreme values: 13 and 72mL/m 2 ), and dilated LA (defined as LA ≥34ml/m 2 ) was found in 34 cases (43%). In univariate analysis, indexed LA volume was significantly linked to age, hypertension (all, p 2 (r=0.5), pulmonary artery systolic pressure (PASP) (r=0.55), mitral E/A ratio (r=0.32), E/e’ ratio (r=0.46), a’ (r=–0.4), LVEF (r=–0.3) (all, p 2 , E/e’, and PASP (all, p 2 , p Conclusion in severe AS with preserved LVEF, LA size is higher in symptomatic patients, and is independently linked to LV remodeling, LV diastolic dysfunction, and PASP, as well as to NT-proBNP a surrogate of increased LV wall stress.

Abstract

Heart failure (HF) complicating acute myocardial infarction (AMI) is of poor prognosis and is often associated with patient's characteristics and success of reperfusion strategies. However, few data is available regarding the high-risk subgroup of patients with anterior AMI treated successfully by primary angioplasty. The aim of the study was to assess the incidence, associated factors, and the future of HF occurring during hospitalisation, in the setting of anterior AMI treated successfully by primary angioplasty.Eighty-five consecutive patients with anterior AMI treated successfully by primary angioplasty (final angiographic TIMI flow grade=3, without residual stenosis) were included. Clinical, biochemical, angiographic, and echocardiographic data were prospectively collected and compared between patients with (Killip 2 and 3) and without HF during hospitalisation.Fifteen patients had HF (18%) during hospitalisation and 70 did not. By comparison to patients without HF, patients with HF were more frequently diabetics, had troponin peak and CPK, leucocytes count, and fasting glucose higher, LVEF and wall motion score index in the left anterior descending territory (WMSi-lad) poorer, and a lower non-invasive coronary flow reserve (CFR) in the LAD 24hours after angioplasty (all, P0.05). In multivariate analysis, fasting glucose, leucocytes count after angioplasty, CFR and WMSi-lad were independently associated with HF, even after adjusting with angiographic variables (all, P0.05). At 6months, patients with HF had less recovery of LV function and higher frequency of adverse LV remodelling (58% versus 20%, P0.01) by comparison to patients without HF.In conclusion, HF is not uncommon even after successful primary angioplasty for anterior AMI (nearly one patient out of 5), is associated with hyperglycaemia and inflammation, a poor microvascular reperfusion, and left ventricular systolic function, and is more frequently complicated by adverse LV remodelling and lack of LV recovery.

After acute myocardial infarction (MI) coronary microvascular impairment and reduced exercise capacity are both determinant of prognosis.We tested whether non-invasive coronary flow reserve (CFR) performed after MI predicts post-MI exercise capacity (EC).Fifty consecutive patients (pts) (mean age 56.5±11years, 30% women) with a first reperfused ST-elevation anterior MI, and sustained TIMI 3 flow after mechanical reperfusion, underwent prospectively non-invasive CFR in the distal part of the left anterior descending artery (LAD), using intravenous adenosine infusion (0.14mg/kg per minute, within 2min), within 24h after successful primary coronary angioplasty (CFR 1), and 4±1.6months later after a period of convalescence and a cardiac rehabilitation program (CFR 2). CFR was defined as peak hyperaemic LAD flow velocity divided by baseline flow velocity. All pts also underwent semi-supine exercise stress echocardiography (ESE) the same day of CFR 2. ESE was performed at an initial workload of 25-30watts with a 20watts increase at 2-minute intervals. Beta-blockers were withheld 24h before ESE.The mean CFR 2 increased significantly when compared to CFR 1 (2.9±0.65 versus 1.9±0.4, P0.01). During ESE, percentage of maximal predict heart rate achieved was 82±12%, maximal workload 95±30watts, exercise duration 486±155s, the ratio of double product 3.1±0.8, and EC 5.8±1.1 metabolic equivalents. No ischemia was induced during ESE in all pts, and the degree of mitral regurgitation did not differ significantly between rest and exercise. CFR 2 was significantly correlated to all indices related to EC (all, P0.01), whereas CFR 1 was correlated to LV systolic function at follow-up (P0.05) but not to EC. In multivariate analysis including age, sex, and body mass index, CFR 2 remained an independent predictor of EC (P0.01).Contrarily to acute CFR, CFR at follow-up is an independent predictor of EC after reperfused anterior MI. This suggests that the improvement of the coronary microcirculation is closely linked to the physical aptitude after MI.

Abstract

To assess left ventricular (LV) twist mechanics in patients with Tako-tsubo cardiomyopathy (TTC). Methods and results Two-dimensional strain and LV twist by speckle-tracking echocardiography was performed in 17 consecutive patients with typical TTC according to the Mayo clinic criteria (78 + 8 years, 88% women, and mean left ventricular ejection fraction (LVEF) 45 + 10%), at the acute phase (within 24 h after admission) and after recovery (1 month later). Seventeen control (C) patients matched for age and sex (mean LVEF 70 + 7%), and 17 patients with acute anterior myocardial infarction (MI) treated by successful primary angioplasty 24 h before, matched for LVEF, age, and sex, were compared with TTC patients. LV twist was assessed using the parasternal basal and apical short-axis planes, and defined as the net difference in degrees of apical (Ar) and basal rotation (Br). Peak systolic and early diastolic, apical (As and Ad) and basal (Bs and Bd) rotation rate, and LV twisting rate (TR) and untwisting rate (UR) (in 8/s) were derived from rotational and twist curves. The time sequences were normalized to the percentage of systolic duration. At the acute phase, Ar, As, Ad, Bs, LV twist (10 + 98 vs. 23 + 68), LV TR, and LV UR were significantly impaired in patients with TTC when compared with controls (all, P , 0.05). Patients with MI displayed intermediate values (P ¼ NS vs. TTC, and P , 0.05 vs. C). However, in the subgroup of patients with electrocardio- gram ST-segment elevation at presentation (n ¼ 12 TTC and 17 MI), several LV twist mechanics parameters were significantly reduced in TTC patients when compared with MI patients, LV twist, and LV TR being the most significant factors (all, P ≤ 0.01). Abnormal reversed Ar (clockwise when seen from the apex) was seen in three patients (18%) with TTC vs. none in the other groups. A significant correlation between LV twist and LVEF, LV volumes, wall motion score index, and plasma NT-pro BNP was observed in the TTC group (all, P , 0.05). At follow-up, LV twist mech- anics improved significantly in TTC patients (all, P , 0.05 vs. acute phase), who had final values similar to C (all, P ¼ NS), whereas the magnitude of improvement was lower in MI patients (P ≤ 0.05 vs. TTC). Conclusion LV twist mechanics is significantly impaired in patients with TTC mainly due to a severe reduction in apical function and is entirely reversible. Furthermore, in the subgroup of patients with ST-segment elevation, the early post-admis- sion evaluation of LV twist mechanics is more severely impaired in TTC when compared with MI.

Abstract

Left ventricular (LV) twist is increased in aortic stenosis (AS) and the hypothesis of a compensatory mechanism is suggested but not established. Our aim was to assess LV twist mechanics in severe AS (1cm(2) or 0.6cm(2)/m(2)) with preserved LV ejection fraction (LVEF50%), and to analyze its relationship with LV systolic longitudinal function, early impaired in this setting, LV diastolic function, and symptomatic status.Forty-five consecutive patients with severe AS and preserved LVEF (mean age 73±11 years, 47% female, LVEF 68±11%, 67% symptomatic) underwent a transthoracic echocardiography including a bidimensional strain analysis by speckle tracking method, and were compared to a control group matched for age and sex (n=15). Global longitudinal strain (GLS) was measured using the four, two, and three apical views, and LV twist mechanics from the basal and apical short axis views. LV twist was defined as the net difference between apical and basal rotation, and LV twisting and untwisting rate (in°/s) were derived from twist curves.Peak apical rotation, LV twist (25±8° vs 20±6), as well as peak systolic and diastolic apical rotation rate, and peak LV twisting rate were significantly higher in patients with AS when compared to controls (all, P0.05), whereas, the other parameters of LV twist mechanics including basal rotation, were not significantly different between groups. By contrast, the GLS was significantly lower in patients with AS when compared to controls (-17.9±4 vs -20.5±2%, P0.01). In addition, the GLS was significantly correlated to LV torsion (r=-0.42, P0.01). Moreover, LV twist progressively impaired with the worsening of diastolic dysfunction and with symptoms onset.LV twist is increased in severe AS with preserved LVEF, compensating the impairment of systolic longitudinal function. However, above a certain threshold LV twist deteriorates, attesting the failure of the compensatory mechanisms, leading to advanced diastolic dysfunction and symptom onset.

Abstract

Objective To assess the relationship between blood cells before and after successful primary angioplasty (PA), and non-invasive coronary flow reserve (CFR), left ventricular (LV) function, and in-hospital adverse events (AE), in patients (pts) with ST-elevation myocardial infarction (STEMI). Methods Blood cells count, on admission (Ad) and within 24 h after PA, and cell differential count on Ad, was obtained in 58 consecutive pts (mean age 58 ± 13 years, 18 women) with first anterior STEMI. Transthoracic Doppler echocardiography was performed prospectively 24 h after PA and at 3 months follow-up (fu), measuring non invasive CFR in the distal part of the left anterior descending artery (LAD) with intravenous adenosine, LV ejection fraction (LVEF) (biplane Simpson's rule), and infarct zone wall motion score (IZWMS). In-hospital AE was a composite of death, heart failure (Killip ≥ 2), and reinfarction. Results Using a ROC curve analysis, the best cut-off of acute CFR for the prediction of global LV recovery (LVEF improvement of ≥ 10% at fu) was 1.7 (AUC 0.87, p 1.7 (all, p Conclusion In pts with anterior STEMI, L count is inversely correlated to acute CFR, and to LV function at fu. These links seem higher after than before PA, and N and M cells might play a role in this setting. Furthermore, L count is an independent predictor of acute CFR and AE.
