Abstract Objective We aim to assess the left ventricular strain in patients with ventricular aneurysm(VA) after myocardial infarction(MI) using cardiac magnetic resonance-feature tracking (CMR-FT) and to evaluate its value for long term prognosis of patients.Methods Sixty-five patients who underwent CMR with VA after MI from January 2018 to December 2019 in Drum Tower Hospital Affiliated Hospital of Nanjing University School of Medicine were selected for the study. They were divided into two groups based on New York Heart Association (NYHA): 25 cases of NYHA I as group A and 40 cases of NYHA II-IV as group B. CMR was performed in both groups to quantify the parameters of overall and segmental left ventricular myocardial strain in patients with aneurysm. 37 of whom underwent a second CMR 3-12 months after cardiac infarction to investigate the effects of aneurysm on patients' left ventricular strain and left ventricular cardiac function.Results Patients from group B have larger VA basilar transverse diameter and significant more impaired LV Global longitudinal strain(GLS)、Global circumferential strain(GCS)、Global radial strain(GRS) (-12.34±7.31 vs. -7.68±6.11;p=0.0072, -21.31±13.49 vs. -14.93±10.44;p=0.0361, 37.13±27.87 vs. 22.00±20.05;p=0.0135) without change in infarct size. GLS, GCS, GRS were significant indicators of NYHA classification after AMI by multivariate regression analysis.Conclusions Myocardial strain assessed by CMR-FT may be an independent predictor of NYHA of patients with aneurysm after MI and could be used for identifying high-risk patients with VA.

The Relationship

Abstract Background Cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) is the gold standard for detection of myocardial scar. We hypothesized that CMR Feature Tracking (FT)-derived regional myocardial strain may reflect the presence of scar and could thus potentially be used instead of LGE imaging. Purpose The aim of this study was to determine the relationship between FT-derived regional myocardial strain and LGE in patients with coronary artery disease (CAD). Methods Seventy-five patients with CAD and typical ischemic LGE patterns on CMR (1.5T) were included (mean age 60±12 years, 70% males). Myocardial strain analysis and LGE identification were performed using dedicated commercial software. Scar was defined by presence of LGE in the same area of the myocardium in both short- and long-axis views. Peak systolic regional longitudinal and circumferential strain (RLS, RCS) values were calculated in the region of interest corresponding to the LGE area and also in a non-LGE myocardial region as a reference in each patient. These comparisons were repeated for a subgroup of 36 patients with left ventricular (LV) ejection fraction (EF) <40% to determine whether the relationship between strain and LGE holds in the presence of reduced LV function, when strain measurements may be altered as a reflection of reduced LVEF itself. Results Both global longitudinal and circumferential strain values were abnormal (−12.8±5.1% and −11.4±4.1%, respectively), reflecting LV dysfunction in this CAD cohort (EF = 40±16%). The magnitude of both RLS and RCS was significantly reduced in areas of LGE, compared to those without LGE: RLS −10.0±5.8% versus −20.4±7.5% (p<0.001); RCS −10.1±5.3±% versus −18.9±7.5%, respectively (p<0.001). Same pattern was noted in the reduced EF subgroup: RLS −8.0±4.7% versus −16.9±6.6% (p<0.001), RCS −7.7±4.3±% versus −16.0±7.9%, respectively (p<0.001). The figure depicts 2 representative cases in long and short axis views, LGE detection and concomitant regional strain analysis. LGE and regional strain analysis. Conclusion Reduced magnitude of regional longitudinal and circumferential strain by CMR-FT correlates with presence of LGE. Pending further validation, this finding may constitute the basis for detection of scar without contrast enhanced imaging, and would result in reduced cost, scan time and risk associated with gadolinium.

Abstract Purpose The aim of the study was to assess a relationship between the occurrence of rheumatoid arthritis (RA) and its selected clinical parameters, and left ventricular myocardial strain. Material and methods Fifty-six subjects were qualified for the study: 30 RA patients and 26 subjects without rheumatoid diseases. The study design included taking medical history, assessment of the disease activity using selected scales of activity, collecting samples of venous blood to assess selected laboratory parameters and the assessment of cardiac magnetic resonance (CMR). Using the feature tracking method, the following parameters of the left ventricular myocardial strain were assessed: longitudinal strain (LS), radial strain (RS) and circumferential strain (CS). Results Regarding global values, peak LS and peak CS were statistically significantly lower in RA patients than in the control group. In the whole study group, the factors independently related to low global LS peaks were as follows: occurrence of RA, occurrence of arterial hypertension, increased activity of antibodies against cyclic citrullinated peptide and increased concentration of neutrophil gelatinase-associated lipocalin. The occurrence of RA, occurrence of diabetes, tobacco smoking, higher activity of antibodies against cyclic citrullinated peptide and current use of methotrexate are the risk factors for low peak of global CS. The current use of steroids constitutes a protecting factor against low global CS peaks. Conclusion In subjects with no clinically manifested cardiac damage, RA is associated with a deteriorated left ventricular systolic function assessed by left ventricular myocardial strain measured by CMR feature tracking.
