OBJECTIVES: We sought to determine the relationship of adverse diastolic remodeling (ie, worsening diastolic or persistent restrictive filling) with infarct scar characteristics, and to evaluate its prognostic value after ST-segment elevation myocardial infarction (STEMI). BACKGROUND: Severe diastolic dysfunction (restrictive filling) has known prognostic value post STEMI. However, ongoing left ventricular (LV) remodeling post STEMI may alter diastolic function even if less severe...

BACKGROUND: Myocardial infarct size (IS) following ST-segment elevation myocardial infarction (STEMI) is an important prognostic factor. We assessed the Selvester 32-point QRS score from the 12-lead ECG for measurement of IS in STEMI patients receiving reperfusion therapy compared to cardiac magnetic resonance imaging (CMRI). Furthermore we sought to explore the impact of microvascular obstruction (MVO) on the scoring system, and determine factors contributing to discrepancies between CMRI IS and Selvester score...

BACKGROUND: Cardiac magnetic resonance imaging (CMR) has been established as a powerful tool for predicting mortality. However, its application is limited by availability and various contraindications. The aim of this study was to evaluate the predictive value of layer-specific myocardial deformation analysis as assessed by strain echocardiography for cardiac events in patients with chronic ischemic left ventricular dysfunction in comparison with CMR. METHODS: Three hundred ninety patients (mean age, 63 ± 4 years; 69% men; mean left ventricular ejection fraction [LVEF], 41 ± 7%) with chronic ischemic cardiomyopathy were prospectively enrolled and underwent strain echocardiography and CMR within 3 ± 1 days...

BACKGROUND: The euroSCORE II is a widely used pre-coronary artery bypass graft surgery (CAGS) risk score, but its predictive power lacks the specificity to predict outcomes in high-risk patients (<LVEF 40%) due to changes in cardiac surgery case mix, revascularisation techniques and related outcomes in recent years. We investigated the utility of Cardiac Magnetic Resonance Imaging (CMRI) in predicting immediate and six-week outcomes after CAGS. METHODS: Fifty-two consecutive patients with high euroSCORE II (>16) and left ventricular (LV) dysfunction (<40%) based on 2D-echocardiography who underwent CAGS and in whom CMRI (1...

BACKGROUND: Whole body cardiovascular MR (WB CVMR) combines whole body angiography and cardiac MR assessment. It is accepted that there is a high disease burden in patients with diabetes, however the quantification of the whole body atheroma burden in both arterial and cardiac disease has not been previously reported. In this study we compare the quantified atheroma burden in those individuals with and without diabetes by clinical cardiovascular disease (CVD) status. METHODS: 158 participants underwent WB CVMR, and were categorised into one of four groups: (1) type 2 diabetes mellitus (T2DM) with CVD; (2) T2DM without CVD; (3) CVD without T2DM; (4) healthy controls...

BACKGROUND: Cardiac sarcoidosis (CS) generates myocardial scar and arrhythmogenic substrate. CS diagnosis according to the Japanese Ministry of Health and Welfare guidelines relies, among others, on cardiac magnetic resonance imaging with late gadolinium enhancement (CMR-LGE). However, access to CMR-LGE is limited. The electrocardiography-based Selvester QRS score has been validated for identifying myocardial scar in ischemic/nonischemic cardiomyopathy, but its efficacy has not been tested to evaluate CS...

BACKGROUND: The Selvester QRS score is an electrocardiographic tool designed to quantify myocardial scar. It was updated in 2009 to expand its usefulness in patients with conduction abnormalities such as bundle-branch and fascicular blocks. There is need to further validate the updated score in a broader group of patients with cardiovascular disease and conduction abnormalities. We primarily hypothesized that the updated score could distinguish between presence and absence of scar by cardiac magnetic resonance imaging (CMR) with late gadolinium enhancement in 4 groups of patients with distinct conduction abnormalitites...

BACKGROUND: The presence of myocardial scar detected by late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging has been described as a good independent predictor of mortality in patients with hypertrophic cardiomyopathy (HCM). Time-domain T-wave alternans (TWA) is also a potential predictor of cardiac mortality in patients with left ventricular dysfunction. OBJECTIVE: The purpose of this study was to elucidate the relationship between LGE distribution and TWA in patients with HCM...

Myocardial infarction (MI) results in myocardial scarring which can have an impact on left ventricular (LV) stiffness and contractile function, ultimately leading to reduced LV systolic function and LV remodelling, However some concerns about the relation between scar extension and segmental wall motion contractility is not enough clear. Thus, the association between myocardial scar, LV regional and global function and LV remodeling should be investigated. We studied the relationship between scar extension, wall motion score index (WMSI), LV dimensions and systolic function in a group of patients with previous MI by cardiac magnetic resonance (CMR)...

AIM: Late gadolinium enhanced (LGE) magnetic resonance imaging (MRI) is a useful tool for facilitating ventricular tachycardia (VT) ablation. Unfortunately, most VT ablation candidates often have prophylactic implantable cardioverter-defibrillator (ICD) and do not undergo cardiac MRI largely due to image artefacts generated by ICD. A prior study has reported success of 'wideband' LGE MRI for imaging myocardial scar without image artefacts induced by ICD at 1.5T. The purpose of this study was to widen the availability of wideband LGE MRI to 3T, since it has the potential to achieve higher spatial resolution than 1...

BACKGROUND: Late gadolinium enhancement (LGE) on cardiac MRI (CMR) has been described as an independent predictive factor of cardiovascular events among patients with hypertrophic cardiomyopathy (HCM). LGE and Q waves are considered as myocardial scar markers but their relation in the context of HCM is poorly established and has to be more supported. The objective of the study was to compare ECG findings in the presence or absence of LGE. METHODS: 42 patients with HCM confirmed by CMR were included in the study...

BACKGROUND: Late gadolinium enhancement (LGE) magnetic resonance imaging (MRI) is a useful technique for detecting myocardial fibrosis. LGE images are typically acquired using the inversion recovery (IR) method. Recently, phase-sensitive inversion recovery (PSIR) technology has been developed. The purpose of this study was to evaluate free-breathing 3D PSIR sequencing in comparison with breath-held 3D IR sequencing for the detection of myocardial fibrosis. METHODS: One hundred twenty-three patients with suspected ischemic cardiac disease (n=27) or non-ischemic cardiomyopathy (hypertrophic cardiomyopathy, n=29; dilated cardiomyopathy, n=22; sarcoidosis, n=21; arrhythmia, n=9; myocarditis, n=4; amyloidosis, n=3; and others, n=8) were evaluated by LGE-MRI, which was performed first with the IR sequence and then with the PSIR sequence, using a 3T MRI scanner...

BACKGROUND: Infarct heterogeneity has been shown to be independently associated with adverse outcomes in previous smaller studies. However, it is unknown whether infarct characterization is an independent predictor of all-cause mortality in patients with advanced ischemic cardiomyopathy, after adjusting for clinical risk factors, severity of ischemic mitral regurgitation, incomplete revascularization, and device therapy. METHODS AND RESULTS: A total of 362 patients with ischemic cardiomyopathy (left ventricular dysfunction with >70% stenosis in ≥1 epicardial coronary artery) underwent delayed hyperenhancement-magnetic resonance imaging and coronary angiography between 2002 and 2006...

UNLABELLED: Cardiac magnetic resonance (CMR) identifies important prognostic variables in ischemic cardiomyopathy (ICM) patients such as left ventricular (LV) volumes, LV ejection fraction (LVEF), peri-infarct zone, and myocardial scar burden (MSB). It is unknown whether Doppler-based diastolic dysfunction (DDF) retains its prognostic value in ICM patients, in the context of current imaging, medical, and device therapies. METHODS: Diastolic function was evaluated in ICM patients (LVEF ≤ 40% and ≥ 70% stenosis in ≥ 1 coronary artery) who underwent transthoracic echocardiogram and delayed hyperenhancement CMR studies within 7 days...

RATIONALE: Although accumulating data support the efficacy of intramyocardial cell-based therapy to improve left ventricular (LV) function in patients with chronic ischemic cardiomyopathy undergoing CABG, the underlying mechanism and impact of cell injection site remain controversial. Mesenchymal stem cells (MSCs) improve LV structure and function through several effects including reducing fibrosis, neoangiogenesis, and neomyogenesis. OBJECTIVE: To test the hypothesis that the impact on cardiac structure and function after intramyocardial injections of autologous MSCs results from a concordance of prorecovery phenotypic effects...

Microvolt T-wave alternans (MTWA) is an electrocardiographic marker for predicting sudden cardiac death. In this study, we aimed to study the relation between MTWA and scar assessed with cardiac magnetic resonance imaging (CMR) in patients with ischemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM). Sixty-eight patients with positive or negative MTWA and analysable CMR examination were included. Using CMR and the delayed enhancement technique, left ventricular ejection fraction (LVEF), volumes, wall motion and scar characteristics were assessed...

AIMS: Intra-myocardial transplantation of CD133(+) bone marrow stem cells (BMC) yielded promising results in clinical pilot trials. We now performed the double-blinded, randomized, placebo-controlled CARDIO133 trial to determine its impact on left ventricular (LV) function and clinical symptoms. METHODS AND RESULTS: Sixty patients with chronic ischaemic heart disease and impaired LV function (left ventricular ejection fraction, LVEF <35%) were randomized to undergo either coronary artery bypass grafting (CABG) and injection of CD133(+) BMC in the non-transmural, hypokinetic infarct border zone (CD133), or CABG and placebo injection (placebo)...
