    Abstract In pulmonary hypertension (PH), right ventricular (RV) performance determines survival. Pulmonary artery (PA) stiffening is an important biomechanical event in PH and also predicts survival based on the PA relative area change (RAC) measured at rest using magnetic resonance imaging (MRI). In this exploratory study, we sought to generate novel hypotheses regarding the influence of stress RAC on PH prognosis and the interaction between PA stiffening, RV performance and survival. Fifteen PH patients underwent dobutamine stress-MRI (ds-MRI) and right heart catheterization. RAC

    Abstract Greater numbers of children with congenital heart disease are surviving to adulthood. The non-invasive assessment and surveillance of these patients, still based primarily on transthoracic echocardiography, has been significantly enhanced by the advent, and more widespread use of, cardiac magnetic resonance imaging. We report on the influence of cardiac magnetic resonance imaging in the initial evaluation of, and response to treatment in, a patient who had developed an obstruction within her Fontan circuit.

    Abstract Background: Chronic kidney disease (CKD) is associated with increased cardiovascular morbidity and mortality. We hypothesized that the level of proteinuria would correlate with left ventricular mass, providing a potential link between elevated protein excretion, left ventricular hypertrophy (LVH) and the increased mortality seen in patients with CKD. In order to do this, we assessed the determinants of left ventricular mass, measured using cardiac magnetic resonance (CMR) imaging, in patients with CKD.
    Methods: Patients attending the renal clinic with CKD stages 2-4 and diabetic nephropathy (n = 26) and IgA nephropathy (n = 23) were recruited. They underwent detailed demographic, biochemical and vascular phenotyping and CMR imaging. Proteinuria was measured using spot protein:creatinine ratio (PCR). Left ventricular mass index (LVMI) was calculated from short-axis cine imaging using Argus software and adjusted for body surface area.
    Results: Log-PCR correlated significantly with LVMI, as did waist circumference, pulse pressure and systolic blood pressure. LVMI was higher in men. When these variables were entered into a linear regression model, log-PCR (P = 0.006) and systolic blood pressure (P < 0.001) independently predicted LVMI. Renal function was not associated with LVMI.
    Conclusions: Using volume-independent CMR imaging, we have demonstrated that the level of urinary protein excretion is independently and significantly associated with left ventricular mass in patients with CKD. This relationship was independent of blood pressure. This finding provides a novel link between CKD and increased cardiovascular risk.

    Abstract Background: Alterations in the balance between matrix metalloproteinases and their endogenous tissue inhibitors (TIMPs) are associated with left ventricular (LV) remodeling after acute myocardial infarction (AMI). No relationships have been identified between TIMPs and serial postinfarction change in LV function.
    Methods and results: Plasma concentrations of TIMP-1, -2, -4 were measured at baseline (mean 46 h) and at 24 weeks in 100 patients (age 58.9 ± 12 years, 77% male) admitted with AMI and LV dysfunction, with cardiac magnetic resonance imaging at each time point. TIMP-1 concentration was reduced, whereas TIMP-2 and -4 concentrations were elevated at baseline compared with a reference control population. TIMP-1 decreased and TIMP-2 increased significantly over time; there was an incremental trend in TIMP-4 concentration. Baseline TIMP-4 correlated with change in LV end-systolic volume index (∆LVESVI; r = 0.24; P = .023) and change in LV end-diastolic volume index (∆LVEDVI; r = 0.25; P = .015). ∆TIMP-4 also correlated with ∆LVESVI and with ∆LVEDVI, as did ∆TIMP-2. On multivariable analysis, baseline TIMP-4 concentration was an independent predictor of ∆LVESVI.
    Conclusions: Plasma TIMP-4 concentration, measured early after AMI, may assist in the prediction of LV remodeling and therefore in the assessment of prognosis. Further study of the role of the TIMPs in the pathophysiology of postinfarction remodeling is warranted.

    Abstract Aims: Mineralocorticoid receptor (MR) antagonists improve cardiovascular outcomes in patients with heart failure complicating acute myocardial infarction (AMI) and in chronic heart failure. It is unclear whether these beneficial effects are due solely to aldosterone blockade, as MR has a similar affinity for cortisol. We examined the relationships between plasma and urinary steroid hormones and left ventricular (LV) remodelling in patients with LV dysfunction following AMI.
    Methods and results: Plasma concentrations of renin, aldosterone, and N-terminal pro-brain natriuretic peptide (NT-proBNP), and 24 h urinary excretion rates of tetrahydroaldosterone (THAldo) and total cortisol metabolites were measured in 93 patients at a mean of 46 h following AMI prior to contrast-enhanced cardiac magnetic resonance (ceCMR). Patients were then randomized to 24 weeks of placebo or eplerenone therapy in addition to standard treatment, after which ceCMR was repeated. In placebo-treated patients, aldosterone, NT-proBNP, and excretion rates of THAldo and total cortisol metabolites were univariate predictors of remodelling (i.e. change in LV end-systolic volume index); aldosterone (P = 0.040) and total cortisol metabolite excretion (P = 0.038) remained independent predictors on multivariate analysis. None of the measured biomarkers predicted remodelling in the presence of eplerenone. Plasma and urinary aldosterone measures, and urinary cortisol metabolites, were not only related to larger infarct volumes and greater infarct remodelling over time, but were also higher in patients with microvascular obstruction on baseline ceCMR.
    Conclusion: Aldosterone and cortisol are associated with medium-term LV remodelling when measured early after AMI. The beneficial effects of MR antagonism may relate to blockade of both aldosterone- and cortisol-induced MR activation.

    Abstract Background and objectives: Premature cardiovascular (CV) events, especially sudden cardiac death, are common in ESRD patients and associated with uremic cardiomyopathy. Identification of high-risk patients is difficult. Microvolt T-wave alternans (MTWA) is a noninvasive method of detecting variability in electrocardiogram (ECG) T-wave morphology and is a promising technique for identifying patients at high risk of ventricular tachyarrhythmias. MTWA results of ESRD and hypertensive left ventricular hypertrophy (LVH) patients were assessed to determine the prevalence of abnormal results and associations with uremic cardiomyopathy.
    Design, setting, participants, & measurements: In this single-center observational study, 200 ESRD and 30 LVH patients underwent assessment including CV history, ECG, cardiac magnetic resonance imaging, and an MTWA exercise test. MTWA results were classified as "negative" or "abnormal" on the basis of previously published reports.
    Results: An abnormal MTWA result was more common in ESRD compared with LVH patients (57.5% versus 26.7%, respectively; P = 0.002). In ESRD patients, MTWA was significantly associated with uremic cardiomyopathy, clinical history of atherosclerosis (coronary, cerebral, peripheral) and diabetes mellitus, older age, and hemodialysis therapy. Independent associations with an abnormal MTWA result were older age, macrovascular disease, increased left ventricle (LV) mass, and LV dilation.
    Conclusions: Features of uremic cardiomyopathy are associated with an abnormal MTWA result.

    Abstract Background: Left ventricular ejection fraction (LVEF) is a powerful prognostic marker after acute myocardial infarction and is dependent on infarct magnitude. Contrast-enhanced cardiac magnetic resonance (ceCMR) represents the current criterion standard means of LVEF and infarct size measurement. Infarct size and LVEF can be estimated from the 12-lead electrocardiogram (ECG) using the Selvester QRS score. We examined for the first time the relationship between serial measures of LVEF and infarct size by ceCMR and ECG in patients with reperfused anterior ST-elevation myocardial infarction (STEMI) and depressed LVEF.
    Methods: Thirty-four patients (mean +/- SD age, 59 +/- 11.8 years; 70.6% male) underwent ceCMR and simultaneous ECG at mean 93 hours after admission and at 12 and 24 weeks. The QRS score was calculated on each ECG, from which infarct size and LVEF were estimated and compared with the equivalent ceCMR measurements.
    Results: Infarct size on ceCMR was higher than that by QRS score at each time-point (P < .001) with modest correlation (r = 0.56-0.78, P < .001). Left ventricular ejection fraction was consistently significantly higher on CMR than on ECG, with weak correlation (r = 0.37-0.51, P < .05). We derived a novel equation relating QRS score to CMR-measured LVEF in the subacute phase of infarction: LVEF = 61 - (1.7 x QRS score) (%).
    Conclusions: In patients with reperfused anterior ST-elevation myocardial infarction and depressed LVEF, ceCMR is moderately correlated with the QRS in the serial measurement of infarct size and LVEF. Infarct size (measured by ceCMR) and LVEF are consistently higher than those calculated on the QRS score in the acute and subacute phases of infarction.
