Effect of Early Metoprolol During ST-Segment Elevation Myocardial Infarction on Left Ventricular Strain:Feature-Tracking Cardiovascular Magnetic Resonance Substudy From the METOCARD-CNIC trial
OBJECTIVES: This study sought to evaluate the effect of early intravenous metoprolol on left ventricular (LV) strain assessed with feature-tracking cardiovascular magnetic resonance (CMR). BACKGROUND: Early intravenous metoprolol before primary percutaneous coronary intervention (PCI) in ST-segment elevation myocardial infarction (STEMI) portends better outcomes in the METOCARD-CNIC (Effect of Metoprolol in Cardioprotection During an Acute Myocardial Infarction) trial. METHODS: A total of 197 patients with acute anterior STEMI who were enrolled in the METOCARD-CNIC trial (100 allocated to intravenous metoprolol before primary PCI and 97 control patients) were evaluated. LV global circumferential strain (GCS) and global longitudinal strain (GLS) were measured with feature-tracking CMR at 1 week and 6 months after STEMI and compared between randomization groups. RESULTS: Patients who received early intravenous metoprolol had significantly more preserved LV strain compared with the control patients at 1 week after STEMI (GCS -13.9 ± 3.8% vs. -12.6 ± 3.9%, respectively; p = 0.013; GLS -11.9 ± 2.8% vs. -10.9 ± 3.2%, respectively; p = 0.032). In both groups, LV strain significantly improved during follow-up (mean difference between 6-month and 1-week strain for the metoprolol group: GCS -2.9%, 95% confidence interval [CI]: -3.5% to -2.4%; GLS: -2.9%, 95% CI: -3.4% to -2.4%; both p < 0.001; the control group: GCS -3.4%, 95% CI: -3.9% to -2.8%; GLS -3.4%, 95% CI: -3.9% to -3.0%; both p < 0.001). When dividing the overall cohort of patients in quartiles of GCS and GLS, there were significantly fewer patients in the first quartile (i.e., the worst LV systolic function) who received early intravenous metoprolol compared with control patients at 1 week and 6 months (p < 0.05 for GCS and GLS at both time points). CONCLUSIONS: In patients with anterior STEMI, early administration of intravenous metoprolol before primary PCI was associated with significantly fewer patients with severely depressed LV GCS and GLS, both at 1 week and 6 months. Feature-tracking CMR represents a complementary tool to evaluate the benefits of cardioprotective therapies.

Left ventricular functional recovery of infarcted and remote myocardium after STsegment elevation myocardial infarction (METOCARD-CNIC randomized clinical trial substudy)
Background: We aimed to evaluate the effect of early intravenous metoprolol treatment, microvascular obstruction (MVO), intramyocardial hemorrhage (IMH) and adverse left ventricular (LV) remodeling on the evolution of infarct and remote zone circumferential strain after acute anterior ST-segment elevation myocardial infarction (STEMI) with feature-tracking cardiovascular magnetic resonance (CMR). Methods: A total of 191 patients with acute anterior STEMI enrolled in the METOCARD-CNIC randomized clinical trial were evaluated. LV infarct zone and remote zone circumferential strain were measured with feature-tracking CMR at 1 week and 6 months after STEMI. Results: In the overall population, the infarct zone circumferential strain significantly improved from 1 week to 6 months after STEMI (− 8.6 ± 9.0% to − 14.5 ± 8.0%; P < 0.001), while no changes in the remote zone strain were observed (− 19.5 ± 5.9% to − 19.2 ± 3.9%; P = 0.466). Patients who received early intravenous metoprolol had significantly more preserved infarct zone circumferential strain compared to the controls at 1 week (P = 0.038) and at 6 months (P = 0.033) after STEMI, while no differences in remote zone strain were observed. The infarct zone circumferential strain was significantly impaired in patients with MVO and IMH compared to those without (P < 0.001 at 1 week and 6 months), however it improved between both time points regardless of the presence of MVO or IMH (P < 0.001). In patients who developed adverse LV remodeling (defined as ≥ 20% increase in LV end-diastolic volume) remote zone circumferential strain worsened between 1 week and 6 months after STEMI (P = 0.036), while in the absence of adverse LV remodeling no significant changes in remote zone strain were observed.CNIC Translational Grant 01–2009Spanish Ministry of Health and Social Policy (EC10–042)Mutua Madrileña Foundation (AP8695–2011)ISCIII Fondo de Investigación Sanitaria grants and ERDF/ FEDER funds (PI16/02110, DTS17/00136, PI13/01979, SAF2015–71613-REDI)MINECO award SEV-2015-05055.364 JCR (2020) Q1, 20/133 Radiology, Nuclear Medicine & Medical Imaging2.558 SJR (2020) Q1, 26/349 Cardiology and Cardiovascular MedicineNo data IDR 2020UE
Current Clinical Use of Speckle Tracking Strain Imaging: Insights from a Worldwide Survey from the European Association of Cardiovascular Imaging-EACVI
International audienceBACKGROUND: Echocardiographic speckle-tracking strain imaging (STE) has been a major advance in myocardial function quantification. We aimed to explore current world-wide clinical application of STE. METHODS: Access, feasibility, access, and clinical implementation of STE were investigated with a worldwide open-access online survey of the European Association of Cardiovascular Imaging (EACVI). RESULTS: Participants (429 respondents, 77 countries) from tertiary centers (46%), private clinics or public hospitals (54%) using different vendors for data acquisition and analysis were represented. Despite almost universal access (98%) to STE, only 39% of the participants performed and reported STE results frequently (>50%). Incomplete training and time constraints were the main reasons for not using STE more regularly. STE was mainly used to assess the left ventricular (99%) and less frequently the right ventricular (57%) and the left atrial (46%) function. Cardiotoxicity (88%) and cardiac amyloidosis (87%) were the most frequent reasons for the clinical use of left ventricular STE. Left atrial STE was used most frequently for the diagnosis of diastolic dysfunction and right ventricular STE for the assessment of RV function in pulmonary hypertension (51%). Frequency of STE use, adherence to optimal techniques and clinical appropriateness of STE differed according to training experience and across vendors. Key suggestions outlined by respondents to increase the clinical use of STE included improved reproducibility (48%) and standardization of strain values across vendors (42%). CONCLUSIONS: Although STE is now readily available, it is underutilized in the majority of centers. Structured training, improved reproducibility and inter-vendor standardization may increase its uptake
Use of cardiac imaging in chronic coronary syndromes: the EURECA Imaging registry
BACKGROUND
The prospective, multicentre EURECA registry assessed the use of imaging and adoption of the European Society of Cardiology (ESC) Guidelines (GL) in patients with chronic coronary syndromes (CCS).
METHODS
Between May 2019 and March 2020, 5156 patients were recruited in 73 centres from 24 ESC member countries. The adoption of GL recommendations was evaluated according to clinical presentation and pre-test probability (PTP) of obstructive coronary artery disease (CAD).
RESULTS
The mean age of the population was 64 ± 11 years, 60% of patients were males, 42% had PTP >15%, 27% had previous CAD, and ejection fraction was <50% in 5%. Exercise ECG was performed in 32% of patients, stress imaging as the first choice in 40%, and computed tomography coronary angiography (CTCA) in 22%. Invasive coronary angiography (ICA) was the first or downstream test in 17% and 11%, respectively. Obstructive CAD was documented in 24% of patients, inducible ischaemia in 19%, and 13% of patients underwent revascularization. In 44% of patients, the overall diagnostic process did not adopt the GL. In these patients, referral to stress imaging (21% vs. 58%; P < 0.001) or CTCA (17% vs. 30%; P < 0.001) was less frequent, while exercise ECG (43% vs. 22%; P < 0.001) and ICA (48% vs. 15%; P < 0.001) were more frequently performed. The adoption of GL was associated with fewer ICA, higher proportion of diagnosis of obstructive CAD (60% vs. 39%, P < 0.001) and revascularization (54% vs. 37%, P < 0.001), higher quality of life, fewer additional testing, and longer times to late revascularization.
CONCLUSIONS
In patients with CCS, current clinical practice does not adopt GL recommendations on the use of diagnostic tests in a significant proportion of patients. When the diagnostic approach adopts GL recommendations, invasive procedures are less frequently used and the diagnostic yield and therapeutic utility are superior
