Abstract
PURPOSE Postmenopausal women experience augmented aortic hemodynamic responses to isometric handgrip (IHG) exercise and metaboreflex activation post-exercise muscle ischemia (PEMI). Relationships between endothelial function brachial artery flow-mediated dilation (FMD) and aortic stiffness carotid-femoral pulse wave velocity (cfPWV) with aortic pulsatile hemodynamics during IHG and PEMI have not been determined. The relationships between aortic hemodynamic responses to PEMI were evaluated. METHODS Aortic blood pressure (BP), wave reflection, and pressure of forward (Pf) and backward (Pb) waves were measured using arterial tonometry at rest, IHG at 30% maximal force, and PEMI in 30 (15/group) postmenopausal women with low (≤ 4.5%) and normal (≥ 5.5%) FMD. Hemodynamic responses were analyzed as the change (Δ) from rest to the last minute of IHG and PEMI. RESULTS Brachial and aortic systolic BP (SBP) responses to IHG were higher in the low vs normal FMD group (P < 0.05). Aortic SBP (Δ20 ± 8 vs Δ11 ± 7 mmHg), pulse pressure (PP) (Δ12 ± 8 vs Δ6 ± 4 mmHg), augmented pressure (AP) (Δ5 ± 3 vs Δ2 ± 2 mmHg), and Pb (Δ6 ± 4 vs Δ3 ± 2 mmHg) responses to PEMI were greater (P < 0.05) in women with low vs. normal FMD. FMD was negatively correlated with aortic SBP, PP, AP, and Pb (P < 0.05) responses to PEMI. cfPWV was not correlated with responses to PEMI. CONCLUSION Endothelial dysfunction relates to augmented aortic pulsatile load during metaboreflex activation, which may increase cardiovascular risk in postmenopausal women.

Abstract
BACKGROUND Fabry disease is a very heterogeneous X-linked lysosomal storage disease. Disease manifestations in the kidneys, heart, and brain vary greatly, even between patients of the same sex and with the same disease classification (classical or nonclassical). A biomarker with a strong association with the development of disease manifestations is needed to determine the need for Fabry-specific treatment and appropriate frequency of follow-up because clinical manifestations of the disorder may take decennia to develop. METHODS We investigated the levels of plasma lysoGb3 levels over time and its association with disease manifestations and disease course in 237 untreated patients with Fabry disease (median age 42 years, 38% male) using linear mixed-effect models. RESULTS LysoGb3 levels are stable over time in plasma of untreated patients with Fabry disease. Higher levels of lysoGb3 were associated with steeper decline in eGFR ( P = 0.05) and a faster increase in albuminuria (measured as the urinary albumin-to-creatinine ratio, P < 0.001), left ventricular mass (measured on echocardiography, P < 0.001), left atrial volume index ( P = 0.003), and Fazekas score ( P = 0.003). In addition, regardless of age, higher lysoGb3 levels were associated with higher relative wall thickness ( P < 0.001) and unfavorable functional markers on echocardiography, including septal mitral annular early diastolic velocity (e', P < 0.001) and the ratio of early transmitral velocity (E) to e' (E/e', P = 0.001). CONCLUSIONS In an individual patient with Fabry disease, the plasma lysoGb3 level reached a specific level in early childhood which, in the absence of Fabry-specific treatment, remained stable throughout life. The level of lysoGb3 in untreated patients was associated with nearly all Fabry-specific disease manifestations, regardless of the sex of the patient.

Abstract
OBJECTIVE The aim of this study was to evaluate the correlation between P-wave indexes, echocardiographic parameters, and CHA2DS2-VASc score in patients without atrial fibrillation and valvular disease. METHODS This retrospective cross-sectional study included patients of a tertiary hospital with no history of atrial fibrillation, atrial flutter, or valve disease and collected data from June 2021 to May 2022. The exclusion criteria were as follows: unavailable medical records, pacemaker carriers, absence of echocardiogram report, or uninterpretable ECG. Clinical, electrocardiographic [i.e., P-wave duration, amplitude, dispersion, variability, maximum, minimum, and P-wave voltage in lead I, Morris index, PR interval, P/PR ratio, and P-wave peak time], and echocardiographic data [i.e., left atrium and left ventricle size, left ventricle ejection fraction, left ventricle mass, and left ventricle indexed mass] from 272 patients were analyzed. RESULTS PR interval (RHO=0.13, p=0.032), left atrium (RHO=0.301, p<0.001) and left ventricle diameter (RHO=0.197, p=0.001), left ventricle mass (RHO=0.261, p<0.001), and left ventricle indexed mass (RHO=0.340, p<0.001) were positively associated with CHA2DS2-VASc score, whereas P-wave amplitude (RHO=-0.141, p=0.02), P-wave voltage in lead I (RHO=-0.191, p=0.002), and left ventricle ejection fraction (RHO=-0.344, p<0.001) were negatively associated with the same score. The presence of the Morris index was associated with high CHA2DS2-VASc (p=0.022). CONCLUSION Prolonged PR interval, Morris index, increased left atrium diameter, left ventricle diameter, left ventricle mass, and left ventricle indexed mass values as well as lower P-wave amplitude, P-wave voltage in lead I, and left ventricle ejection fraction values were correlated with higher CHA2DS2-VASc scores.

Kamel AM, Sabry N, Farid S. Effect of metformin on left ventricular mass and functional parameters in non-diabetic patients: a meta-analysis of randomized clinical trials. BMC Cardiovasc Disord 2022; 22:405. [PMID: 36088302 PMCID: PMC9464374 DOI: 10.1186/s12872-022-02845-w] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2022] [Accepted: 09/01/2022] [Indexed: 11/21/2022] Open
Abstract
Background Left ventricular hypertrophy is a common finding in patients with ischemic heart disease and is associated with mortality in patients with cardiovascular disease (CVD). Metformin, an antidiabetic drug, has been shown to reduce oxidative stress and left ventricular mass index (LVMI) in animal hypertrophy models. We summarized evidence regarding the effect of metformin on LVMI and LVEF. Methods Electronic databases were searched for randomized clinical trials (RCTs) that used metformin in non-diabetic patients with or without pre-existing CVD. The standardized mean change using change score standardization (SMCC) was calculated for each study. The random-effects model was used to pool the SMCC across studies. Meta-regression analysis was used to assess the association of heart failure (HF), metformin dose, and duration with the SMCC. Results Data synthesis from nine RCTs (754 patients) showed that metformin use resulted in higher reduction in LVMI after 12 months (SMCC = −0.63, 95% CI − 1.23; − 0.04, p = 0.04) and an overall higher reduction in LVMI (SMCC = −0.5, 95% CI − 0.84; − 0.16, p < 0.01). These values equate to absolute values of 11.3 (95% CI 22.1–0.72) and 8.97 (95% CI 15.06–2.87) g/m2, respectively. The overall improvement in LVEF was also higher in metformin users after excluding one outlier (SMCC = 0.26, 95% CI 0.03–0.49, P = 0.03) which translates to a higher absolute improvement of 2.99% (95% CI 0.34; 5.63). Subgroup analysis revealed a favorable effect for metformin on LVEF in patients who received > 1000 mg/day (SMCC = 0.28, 95% CI 0.04; 0.52, P = 0.04), and patients with HF (SMCC = 0.23; 95% CI 0.1; 0.36; P = 0.004). These values translate to a higher increase of 2.64% and 3.21%, respectively. Conclusion Results suggest a favorable effect for metformin on LVMI and LVEF in patients with or without pre-existing CVD. Additional trials are needed to address the long-term effect of metformin. Registration The study was registered on the PROSPERO database with the registration number CRD42021239368 (https://www.crd.york.ac.uk/prospero). Supplementary Information The online version contains supplementary material available at 10.1186/s12872-022-02845-w. Metformin therapy regresses LVH by approximately 10 g/m2 in non-diabetic patients after 12 months of use (SMCC = −0.63, 95% CI − 1.23; − 0.04, p = 0.04). Metformin therapy was associated with a modest (2–3%) but greater overall improvement in LVEF. Higher dose (> 1000 mg/day) and longer treatment duration were associated with a significant effect for metformin on LVMI and LVEF. Metformin use in HF patients was associated with an absolute increase of 3.21% in LVEF (SMCC = 0.23; 95% CI 0.1; 0.36, P = 0.004).

Abstract
Different devices for mechanical circulatory support (MCS) have been developed for the treatment of refractory cardiogenic shock. However, all of them are associated with direct blood contact, the need for anticoagulation and bleeding complications. To overcome these limitations the pericardial sac got into the focus as a promising implantation site for MCS. For this purpose, further knowledge about the mechanical properties of human pericardium is required. In this prospective, monocentric, experimental pilot study 56 samples of human pericardium were extracted postmortem from 13 critically ill patients. After preparation of test specimens uniaxial tensile tests were performed. The primary end points were load at fracture per sample width and strain at fracture. Acute inflammation was assessed by blood levels of C-reactive protein, white blood count and procalcitonin measured at several times during hospital stay. Inflammatory load was estimated by area under the inflammatory curves. Correlation and regression analysis were used to assess the relationship of primary end points to inflammation, comorbidities and postmortem time to preparation. Human pericardium showed a load at fracture per sample width of 1.95 [1.38–2.94] N/mm (median [inter quartile range]) and a strain at fracture of 89.29 [73.84–135.23] %. Markers of acute inflammation and cardiac hypertrophy did not correlate to load or strain at fracture. However, strain at fracture increased with higher body mass index and an increasing number of postmortem days. In contrast, higher patient age was associated with a lower strain at fracture. Inflammation and cardiac hypertrophy did not influence mechanical properties of human pericardium.

Abstract
Early repolarization pattern (ERP) is associated with increased mortality in case-control studies, but the mechanism and role of left ventricular mass (LVM) remain unclear. Our objectives were to understand (1) whether ERP associates with adverse outcomes in a multiethnic population and (2) to explore the role of LVM in these associations. Participants from the Dallas Heart Study with an electrocardiogram interpretable for ERP, defined as J point elevation ≥1 mm in 2 contiguous leads, were included. Combined all-cause mortality and nonfatal cardiovascular disease (CVD) events and individual components were assessed using Cox proportional hazards modeling after adjustment for demographics, traditional CVD risk factors, electrocardiogram intervals, and cardiac magnetic resonance imaging-derived factors. Cardiac magnetic resonance imaging-defined LVM was then added to the most fully adjusted model. Of the 2,686 participants, 240 (8.9%) demonstrated ERP. Participants with ERP were more likely to be male and Black, with lower body mass index, greater left ventricular end-diastolic volumes, and LVM. Over a median follow-up of 11 years, the combined end point occurred in 326 patients. Multivariable modeling demonstrated ERP was associated with the combined end point (HR [95% CI] 1.61 [1.14 to 2.26]), all-cause mortality (1.67 [1.00 to 2.80]). However, further adjusting for LVM attenuated the associations of ERP with the primary end point (HR [95% CI] 1.22 [0.85 to 1.77]) and secondary end points of mortality (1.39 [0.80 to 2.41]) and nonfatal CVD (1.05 [0.68 to 1.64]). ERP was associated with increased mortality and nonfatal CVD events, which was attenuated after adjusting for LVM, a previously under-recognized clinical phenotype. Previous associations of ERP with adverse cardiovascular outcomes may be partially explained by greater LVM in those with ERP.

Abstract
The first successful live donor kidney transplant was performed in 1954. Receiving a kidney transplant from a live kidney donor remains the best option for increasing both life expectancy and quality of life in patients with end-stage kidney disease. However, ever since 1954, there have been multiple questions raised on the ethics of live kidney donation in terms of negative impacts on donor life expectancy. Given the close relationship between reduced kidney function in patients with chronic kidney disease (CKD) and hypertension, cardiovascular disease and cardiovascular mortality, information on the impact of kidney donation on these is particularly relevant. In this article, we review the existing evidence, focusing on the more recent studies on the impact of kidney donation on all-cause mortality, cardiovascular mortality, cardiovascular disease and hypertension, as well as markers of cardiovascular damage including arterial stiffness and uraemic cardiomyopathy. We also discuss the similarities and differences between the pathological reduction in renal function that occurs in CKD, and the reduction in renal function that occurs because of a donor nephrectomy. Kidney donors perform an altruistic act that benefits individual patients as well as the wider society. They deserve to have high-quality evidence on which to make informed decisions.

Abstract
Background: Ischemic stroke can be classified into five etiological types, according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, and its adequate investigation and characterization can aid in its clinical management and in preventing new events. Transthoracic echocardiography (TTE) plays a key role in investigating its etiology; approximately one-third of the patients remain without an adequate definition of the etiology or are classified as the undetermined TOAST type. Objectives: To evaluate if the percentage of patients with indeterminate etiology according to the TOAST classification decreased after transthoracic echocardiography, to determine whether or not the prognosis after ischemic stroke is worse among patients classified as the undetermined TOAST type, and to verify the predictive capacity of echocardiography on the prognosis after ischemic stroke. Methods: In this retrospective cohort study, clinical, neurological, and echocardiographic examinations were conducted when the patient was hospitalized for stroke. In-hospital mortality and functional capacity were evaluated at hospital discharge and 90 days thereafter. Multiple linear regression and multiple logistic regression models were adjusted for confounding factors. The level of significance was 5%. Results: A total of 1,100 patients (men = 606; 55.09%), with a mean age of 68.1 ± 13.3 years, were included in this study. Using TTE, 977 patients (88.82%) were evaluated and 448 patients (40.7%) were classified as the undetermined TOAST type. The patients who underwent TTE were 3.1 times less likely to classified as the undetermined TOAST type (OR = 0.32; p < 0.001). Echocardiography during hospitalization was a protective factor against poor prognosis, and reduced the odds of in-hospital death by 11.1 times (OR: 0.090; p < 0.001). However, the presence of the undetermined TOAST classification elevated the chance of mortality during hospitalization by 2.0 times (OR: 2.00; p = 0.013). Conclusions: Echocardiography during hospitalization for ischemic stroke reduces the chances of an undetermined TOAST classification and the risk of in-hospital mortality. However, being classified as the undetermined TOAST type increases the chance of mortality during hospitalization, suggesting that evaluating patients using echocardiography during hospitalization for acute ischemic stroke is important.

An under-recognized phenomenon: Myocardial volume change during the cardiac cycle. Echocardiography 2021; 38:1235-1244.

Abstract
BACKGROUND Myocardial volume is assumed to be constant over the cardiac cycle in the echocardiographic models used by professional guidelines, despite evidence that suggests otherwise. The aim of this paper is to use literature-derived myocardial strain values from healthy patients to determine if myocardial volume changes during the cardiac cycle. METHODS A systematic review for studies with longitudinal, radial, and circumferential strain from echocardiography in healthy volunteers ultimately yielded 16 studies, corresponding to 2917 patients. Myocardial volume in systole (MVs) and diastole (MVd) was used to calculate MVs/MVd for each study by applying this published strain data to three models: the standard ellipsoid geometric model, a thin-apex geometric model, and a strain-volume ratio. RESULTS MVs/MVd<1 in 14 of the 16 studies, when computed using these three models. A sensitivity analysis of the two geometric models was performed by varying the dimensions of the ellipsoid and calculating MVs/MVd. This demonstrated little variability in MVs/MVd, suggesting that strain values were the primary determinant of MVs/MVd rather than the geometric model used. Another sensitivity analysis using the 97.5th percentile of each orthogonal strain demonstrated that even with extreme values, in the largest two studies of healthy populations, the calculated MVs/MVd was <1. CONCLUSIONS Healthy human myocardium appears to decrease in volume during systole. This is seen in MRI studies and is clinically relevant, but this study demonstrates that this characteristic was also present but unrecognized in the existing echocardiography literature.

Abstract
PURPOSE OF REVIEW Echocardiography is a noninvasive tool of choice for evaluating cardiac structure and function in numerous cardiac conditions ranging from congenital heart disease, myocardial diseases, coronary artery disease (CAD), valvulopathies, arrhythmias, and pericardial disorders. We review the prognostic significance of echocardiographic indices of cardiac remodeling in the general population. RECENT FINDINGS Recent meta-analyses have confirmed the prognostic significance of echocardiographic measurements (left ventricular mass/hypertrophy, systolic and diastolic dysfunction, left atrial dimensions and function, and strain rate measures) in asymptomatic people in the community for adverse clinical outcomes including CAD, stroke, heart failure, atrial fibrillation, sudden death, and all-cause mortality. The clinical utility of screening echocardiography has been examined comprehensively in hypertensive patients, where it is challenged by measurement variability. Echocardiographic measures predict cardiovascular disease outcomes consistently in multiple community-based epidemiological studies. However, the clinical utility of screening asymptomatic individuals with echocardiography in population-based settings is limited.

Abstract
OBJECTIVE Research has consistently found associations between sleep characteristics and cardiovascular disease risk in children, adolescents, and adults. Although primarily investigated in clinical samples (e.g., in those with sleep disorders), greater left ventricular mass is associated with poor sleep quality in nonclinical adult populations as well; however, this has not been evaluated in children or adolescents. Our study aim was to consider the relationship between objectively measured sleep characteristics and left ventricular mass in children. METHODS We assessed sleep and cardiac structure in a biracial sample of 9- to 11-year-old children (n = 176; 41% White, 59% Black; 50% female). Sleep was assessed with actigraphy for five nights. Cardiac dimensions were assessed using echocardiography. RESULTS After adjusting for covariates, we found that poor sleep quality was associated with significantly greater left ventricular mass (β = 0.13, t(167) = 2.14, p = .034, Cohen d = 0.16, for activity during sleep; β = 0.15, t(167) = 2.43, p = .016, Cohen d = 0.18, for sleep fragmentation). Other cardiac dimensions (namely, relative wall thickness and right ventricular dimension) were also significantly associated with sleep characteristics. Notably, associations did not differ as a function of sex or race. CONCLUSIONS The present findings are novel and unique because no prior reports have systematically documented the association between poor sleep quality with potentially detrimental cardiac remodeling in a nonclinical sample of children. However, the novelty and importance of these findings require additional research for confirmation.

Abstract
Obesity represents one of the most challenging public health problems of our century. It accounts for approximately 5% of deaths worldwide, mostly owing to cardiovascular disease and its associated complications. Cardiovascular noninvasive imaging may provide early accurate information about hypertrophy and ischemia/fibrosis in obese subjects. Echocardiography and nuclear cardiology have serious limitations in obese subjects owing to poor acoustic window and attenuation artifacts, respectively. Coronary computed tomography angiography can provide information about obstructive coronary disease; however, the use of radiation is a serious disadvantage. Finally, cardiac magnetic resonance (CMR) holds the promise of an "all in one" examination by combining evaluation of function, wall motion/thickness, stress rest/perfusion, replacement and diffuse fibrosis without radiation. Future studies are required to document the cost/benefit ratio of the CMR in the evaluation of cardiovascular risk in overweight/obese children and adolescents.

Abstract
Supplemental Digital Content is available in the text. Kidney donation reduces renal function by ≈30% allowing study of the cardiovascular effects of a reduced estimated glomerular filtration rate without comorbidities. We report 5-year results of a longitudinal, parallel-group, blinded end-point study of living kidney donors (n=50) and healthy controls (n=45). The primary end point, left ventricular mass, was measured using cardiac magnetic resonance. Secondary end points, 24-hour ambulatory blood pressure, and pulse wave velocity were measured using validated blood pressure monitors and the SphygmoCor device. Effect sizes were calculated as differences between change from baseline in the donor and control groups. In donors, estimated glomerular filtration rate was 95±15 mL/min per 1.73 m2 at baseline (predonation) and 67±14 mL/min per 1.73 m2 at 5 years. In controls, there was a −1±2 mL/min per 1.73 m2 decline per annum. Change in left ventricular mass at 5 years was not significantly different between donors and controls (mean difference, +0.40 g [95% CI, −4.68 to 5.49] P=0.876), despite an initial increase in mass in donors compared with controls at 12 months. Pulse wave velocity, which increased in donors at 12 months, returned to levels not different from controls at 5 years (mean difference, −0.24 m/s [95% CI, −0.69 to 0.21]). Change in ambulatory systolic blood pressure was not different in donors compared with controls (mean difference, +1.91 mm Hg [95% CI, −2.72 to 6.54]). We found no evidence that the reduction in estimated glomerular filtration rate after kidney donation was associated with a change in left ventricular mass detectable by magnetic resonance imaging at 5 years.

Abstract
OBJECTIVES People living with HIV (PLWH) have increased risk of cardiovascular diseases compared with uninfected populations. We assessed structural cardiac abnormalities and their associated risk factors in well-treated PLWH and uninfected controls using multidetector computed tomography (MDCT). METHODS People living with HIV and age- and sex-matched uninfected controls underwent MDCT to determine left atrial volume (LAV), left ventricular diastolic volume (LVDV), right ventricular diastolic volume (RVDV) and left ventricular mass (LVM). All outcomes were indexed to body surface area (BSA) (LAVi, LVDVi, RVDVi and LVMi). RESULTS A total of 592 PLWH and 1184 uninfected controls were included in the study. PLWH had smaller mean (SD) LAVi [40 (8) vs. 41 (9) mL/m2 ; P = 0.002] and LVDVi [61 (13) vs. 65 (14) mL/m2 ; P < 0.001] but larger RVDVi [89 (18) vs. 86 (17) mL/m2 ; P < 0.001] than uninfected controls. HIV was independently associated with 7 mL (95% CI: -10 to -3) smaller LVDV, and with 12 mL (95% CI: 8-16) larger RVDV, and 4 g (95% CI: 1-6) larger LVM after adjustment for cardiovascular risk factors and BSA. Large RVDV in PLWH was not associated with obstructive lung function. CONCLUSIONS HIV was independently associated with smaller LVDV and larger RVDV and LVM. Alterations in cardiac chamber volumes in PLWH were mainly minor. The clinical impact of these findings is uncertain, but it seems unlikely that alterations in cardiac chamber volumes explain the increased burden of cardiovascular disease previously observed in PLWH.

Abstract
BACKGROUND The professional guidelines assume that the myocardial volume in systole (MVs) is equal to that in diastole (MVd), despite some limited evidence that points to the contrary. The aim of this manuscript is to determine whether this is true in healthy myocardium using gold standard cardiac MRI, as well as transthoracic echocardiography (TTE). The secondary aim is to determine whether there are similar MV changes in patients with heart failure with reduced ejection fraction (HFrEF). METHOD A prospectively derived cohort at Mayo Clinic of 115 adult subjects (mean age 42.8 years, 58% female) with no cardiac risk factors was identified. Cardiac MRI was obtained on all 115 patients, 51 of whom also consented to a TTE. MRI from a retrospectively derived cohort of 50 HFrEF patients was also collected. MVs and MVd was calculated using standard approaches with inclusion of the papillary muscles. RESULTS In the healthy population, MRI demonstrated MVs/MVd = 0.87 (SD 0.04) and TTE demonstrated MVs/MVd = 0.79 (SD 0.07), suggesting compressibility (p < 0.0001). In the 51 healthy patients who received both imaging modalities, MVs/MVd was 8.0% higher in MRI than TTE (p < 0.0001), but both modalities had MVs/MVd < 1 (p < 0.0001). A Bland-Altman plot demonstrated that as the mean MVs/MVd increases, the difference in MVs/MVd MRI-TTE declines (r = -0.53, p < 0.0001). However, in HFrEF populations, MVs/MVd = 1.01 (0.03), suggesting myocardial incompressibility. CONCLUSION Contrary to currently accepted standards, healthy myocardium is compressible but HFrEF myocardium is incompressible. The ratio MVs/MVd merits further study in an expanded normal cohort and in disease states.

Left Ventricular Hypertrophy and Mortality Risk in Male Veteran Patients at High Cardiovascular Risk. Am J Cardiol 2020; 125:887-893.

Abstract
Several studies addressed cardiovascular risk and mortality in the general population, but data in veteran patients is lacking. This study was designed to investigate the association between echocardiographic left ventricular hypertrophy (LVH) and all-cause mortality in a male, high-risk group of veterans. Valid echocardiograms were evaluated in 10,406 male veterans, mean age 68.3 ± 13 years. Using the left ventricular mass/body surface area (LVM/BSA) method 6,575 (63.1%) patients had normal left LVMI and 3,831 (37.9%) had LVH, defined as LVMI ≥116 g/m2. Of those 1,371 (13.2%) had mild LVH, 1,025 (9.9%) moderate LVH, 605 (5.8%) severe, and 830 (8%) had extreme LVH. After a mean follow up of 5.9 ± 4.4 years, a total of 3,550 (34.1%) patients died. Cox proportional hazard analyses adjusted for co-morbidities revealed increased risk for individuals with mild LVH (hazard ratios [HR] 1.21; 95% confidence intervals [CI]: 1.09 to 1.33); moderate LVH (HR 1.37; 95% CI: 1.23 to 1.52); severe (HR = 1.36; 95% CI: 1.19 to 1.56); and extreme LVH, (HR = 1.95; 95% CI: 1.74 to 2.17). Similar findings were observed when LVMI was defined by LVM/m2.7. When LVM index was introduced as a continuous variable, mortality risk was 6.2% higher per 10-unit change in LVMI, and 9.4% higher when defined by the m2.7 method. There was no difference in mortality risk between black and white patients, or patients with concentric or eccentric LVH. We conclude that increased LVMI was associated with increased risk of all-cause mortality. The incremental risk was significantly higher in patients with extreme LVH.

Abstract
AIM To investigate the molecular, structural, and functional impact of aerosols from candidate modified risk tobacco products (cMRTP), the Carbon Heated Tobacco Product (CHTP) 1.2 and Tobacco Heating System (THS) 2.2, compared with that of mainstream cigarette smoke (CS) on the cardiovascular system of ApoE-/- mice. METHODS Female ApoE-/- mice were exposed to aerosols from THS 2.2 and CHTP 1.2 or to CS from the 3R4F reference cigarette for up to 6 months at matching nicotine concentrations. A Cessation and a Switching group (3 months exposure to 3R4F CS followed by filtered air or CHTP 1.2 for 3 months) were included. Cardiovascular effects were investigated by echocardiographic, histopathological, immunohistochemical, and transcriptomics analyses. RESULTS Continuous exposure to cMRTP aerosols did not affect atherosclerosis progression, heart function, left ventricular (LV) structure, or the cardiovascular transcriptome. Exposure to 3R4F CS triggered atherosclerosis progression, reduced systolic ejection fraction and fractional shortening, caused heart LV hypertrophy, and initiated significant dysregulation in the transcriptomes of the heart ventricle and thoracic aorta. Importantly, the structural, functional, and molecular changes caused by 3R4F CS were improved in the smoking cessation and switching groups. CONCLUSION Exposure to cMRTP aerosols lacked most of the CS exposure-related functional, structural, and molecular effects. Smoking cessation or switching to CHTP 1.2 aerosol caused similar recovery from the 3R4F CS effects in the ApoE-/- model, with no further acceleration of plaque progression beyond the aging-related rate.

Interact Cardiovasc Thorac Surg 2019; 28:58-64. [PMID: 30010890 DOI: 10.1093/icvts/ivy190] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2017] [Accepted: 05/13/2018] [Indexed: 11/13/2022] Open
Abstract
OBJECTIVES The superiority of supra-annular aortic prostheses over intra-annular equivalents in long-term haemodynamics and clinical outcomes remains controversial. This study compared outcomes among patients receiving supra-annular or intra-annular prostheses during aortic valve replacement. METHODS We enrolled 587 consecutive patients (mean age 55.1 ± 11.3 years; 188 women) undergoing aortic valve replacement with either supra-annular (n = 316) or intra-annular (n = 271) mechanical prostheses between 2000 and 2016 in our institute. Clinical outcomes and haemodynamic profiles in the 2 groups were compared after propensity score adjustment. RESULTS Early death (1.1% vs 0.6%; P = 0.863) was equivalent for both groups. Patients receiving supra-annular prostheses showed a lower rate of patient-prosthesis mismatch (1.2% vs 25.8%; P < 0.001). During a median follow-up of 65 months (quartile 1-3, 30-108 months), overall deaths occurred in 84 (14.3%) patients. The latest echocardiographic assessment in the 136 propensity score-matched pairs demonstrated superior haemodynamics with implantation of supra-annular prostheses: peak velocity (2.7 ± 0.6 vs 2.3 ± 0.5 m/s; P < 0.001), mean pressure gradient (16.5 ± 9.0 vs 12.0 ± 6.2 mmHg; P < 0.001) and left ventricular mass index (113.6 ± 30.3 vs 105.3 ± 26.3 g/m2; P = 0.016). After adjusting with inverse-probability-of-treatment weighting, however, the choice of supra-annular over intra-annular prosthesis did not significantly affect the risk of overall mortality (P = 0.693) or major adverse events: stroke (P = 0.944), infective endocarditis (P = 0.958) and reoperation (P = 0.944). CONCLUSIONS The implantation of supra-annular prostheses resulted in superior haemodynamics and left ventricular mass regression, while conferring no apparent clinical benefits. Follow-up studies are required to further evaluate the impact of superior haemodynamics associated with supra-annular prostheses on long-term clinical outcomes.

Abstract
INTRODUCTION Recent reviews have found substantial links between a toxic childhood environment including child abuse and severe household dysfunction and adult cardiovascular disease (CVD). Collectively referred to as adverse childhood experiences (ACEs), this toxic environment is prevalent among children, with recent Canadian estimates of child abuse at 27%-32%, and severe household dysfunction at 49%. Based on these prevalence rates, the potential effect of ACEs on CVD is more significant than previously thought. Yet, how ACEs amplify the risk for later CVD remains unclear. Lifestyle risk factors only partially account for this connection, instead directing attention to the interaction between psychosocial factors and physiological mechanisms such as inflammation. The Niagara Longitudinal Heart Study (NLHS) examines how ACEs influence cardiovascular health (CVH) from childhood to early adulthood. Integrating the stress process and biological embedding models, this study examines how psychosocial and physiological factors in addition to lifestyle factors explain the relationship between ACEs and CVH. METHODS This follow-up study combines three baseline studies from 2007 to 2012 that collected CVH measures including child blood pressure, heart rate, left ventricular structure and function, arterial stiffness indices and baroreflex sensitivity on 564 children. Baseline data also include anthropometric, biological, lifestyle, behavioural, and psychosocial measures that varied across primary studies. Now over 18 years of age, we will recruit and retest as many participants from the baseline studies as possible collecting data on ACEs, CVH, anthropometric, lifestyle and psychosocial measures as well as blood, saliva and hair for physiological biostress markers. ETHICS AND DISSEMINATION Ethics approval has been received for the NLHS follow-up. Written consent to participate in the follow-up study is obtained from each participant. Results testing all proposed hypotheses will be submitted for publication in peer-reviewed journals.

Abstract
Aim. To investigate the impact of amlodipine/valsartan single-pill combination (A/V SPC) on left ventricular hypertrophy (LVH) and left ventricular (LV) myocardial strain and stiffness parameters in naїve middle-aged patients with stage II grade 1-2 essential arterial hypertension (EAH).Material and methods. A group of patients with stage II grade 1-2 EAH who had not previously received regular antihypertensive treatment (AHT) [n=38; mean age 49.7±7.0 years] was retrospectively formed. All the patients were treated with A/V SPC and all of them achieved target office blood pressure (BP) (less than 140/90 mm Hg). And after 12 weeks follow-up (since the time of reaching the target BP) the AHT effectiveness assessment, its impact on LVH and LV myocardial strain and stiffness parameters (general clinical data, ambulatory blood pressure monitoring, conventional and 2D-speckle tracking echocardiography) were performed in all included patients.Results. The number of patients with LVH significantly (p=0.039) decreased from 25 individuals (65.8%) at baseline to 15 patients (39.5%) at the end of follow-up. Among patients with LVH at baseline after the treatment with A/V SPC significantly decreased (p<0.001 for all) interventricular septum thickness (from 1.36±0.19 to 1.28±0.18 cm), LV posterior wall thickness (from 1.08±0.09 to 0.97±0.11 cm) and the LV myocardial mass index (from 123.3±19.3 to 110.8±20.8 g/m2). At the end of follow-up end-systolic elastance significantly (p<0.001) decreased from 4.01±1.12 to 3.46±0.88 mm Hg/ml. In the subgroup of patients with reduced (in absolute value) LV longitudinal 2D-strain (n=27) at baseline, there was a significantly (p=0.005) increasing in this parameter at the end of the study (from -16.14±2.21% to -17.30±2.13%, Δ%=8.45±13.35).Conclusion. In naive patients 40-65 years old with stage II grade 1-2 EAH AHT with A/V SPC provides effective 24 hours BP control, significantly reduced LVH and improves LV strain parameters, which indicates decreasing of LV myocardial stiffness.

Abstract
BACKGROUND Persistent and adequate treatment of patients with arterial hypertension leads to more favorable disease outcome. HYPOTHESIS Aside for the present left ventricular hypertrophy (LVH), there are other non-invasive parameters which can represent additional predictors of unfavorable prognosis in patients with essential arterial hypertension during the 10-year follow-up. METHODS A hypertensive group with LVH (124 patients; age 57.0 ± 8.0; 84 males and 40 females) was included in the study and examined noninvasively. Patients used regular medication therapy during the follow-up period. RESULTS During the 10-year follow-up period, unfavorable outcome was recorded for 40 (32.3%) patients. Patients with unfavorable outcome had higher baseline values of left ventricular mass index (178.9 ± 29.5 g/m2 vs 165.5 ± 29.5 g/m2 ; P < 0.05) and QTc dispersion (64.1 ± 24.7 ms vs 54.8 ± 19.4 ms; P < 0.05). Frequency of positive Cornell product was higher in the group of patients with unfavorable outcome (35% vs 22.2%; P < 0.01). Positive Lyon-Sokolow score did not show statistical significance (25% vs 11.9%; P = 0.06). Cornell product (β = 0.234; P < 0.01) and QTc dispersion >65 ms (β = 0.184; P < 0.05) had prognostic significance in LVH (multiple regression analysis: R = 0.314, R = 0.099, adjusted R = 0.084, standard error of the estimate = 0.449, P < 0.05). CONCLUSIONS Patients with a positive Cornell product and larger QTc dispersion had more unfavorable 10-year outcomes compared with other patients with LVH.

Abstract
Untreated, severe, symptomatic aortic stenosis is associated with a dismal prognosis. The only treatment shown to improve survival is aortic valve replacement; however, before symptoms occur, aortic stenosis is preceded by a silent, latent phase characterized by a slow progression at the molecular, cellular, and tissue levels. In theory, specific medical therapy should halt aortic stenosis progression, reduce its hemodynamic repercussions on left ventricular function and remodeling, and improve clinical outcomes. In the present report, we performed a systematic review of studies focusing on the medical treatment of patients with aortic stenosis. Lipid-lowering therapy, antihypertensive drugs, and anticalcific therapy have been the main drug classes studied in this setting and are reviewed in depth. A critical appraisal of the preclinical and clinical evidence is provided, and future research avenues are presented.

Abstract
BACKGROUND AND AIMS Overall, men have roughly twice the risk of myocardial infarction (MI) compared to women, but what causes this contrast is unclear. Identification of subgroups where the gender contrast in risk is particularly low or high, may provide new insight. In the search for such subgroups, we focus on gender-specific effects of established coronary heart disease (CHD) risk factors. Heterogeneity across age groups is also explored. METHODS Population-based prospective study from Tromsø, Norway, comprising 33,859 individuals (51% women); 2746 individuals (854 women) received a diagnosis of MI during follow-up at ages 35-94 years. Incidence rate ratios (IRR) were calculated as estimates of relative risk in Poisson regression analyses. RESULTS The association between total cholesterol and risk of MI was stronger for men than women, and IRR for men vs. women accordingly increased with increasing cholesterol, but the risk was higher for men in all subgroups (IRR in range 1.63-3.27), except among older people with low cholesterol levels. The adverse effect of increasing blood pressure (BP) was stronger for women, and IRR for gender diminished with increasing systolic (from 3.90 to 1.38) and diastolic BP (from 2.87 to 1.54). The gender contrast in risk was also substantially reduced in smokers ≥75 years. Associations with high-density lipoprotein cholesterol (HDL-C) did not differ between genders. CONCLUSIONS Gender heterogeneity in associations with total cholesterol but not HDL-C indicates gender differences in associations with non-HDL-C. The stronger association with BP in women may relate to more severe hypertension-induced left ventricular hypertrophy.

Abstract
BACKGROUND Obesity affects nearly one in five children and is associated with increased risk of premature death. Obesity-related heart disease contributes to premature death. We aimed to use cardiovascular magnetic resonance (CMR) to comprehensively characterize the changes in cardiac geometry and function in obese children. METHODS AND RESULTS Forty-one obese/overweight (age 12 ± 3 years, 56 % female) and 29 healthy weight children (age 14 ± 3 years, 41 % female) underwent CMR, including both standard cine imaging and displacement encoded imaging, for a complete assessment of left ventricular (LV) structure and function. After adjusting for age, LV mass index was 23 % greater (27 ± 4 g/m(2.7) vs 22 ± 3 g/m(2.7), p <0.001) and the LV myocardium was 10 % thicker (5.6 ± 0.8 mm vs 5.1 ± 0.8 mm, p <0.001) in the obese/overweight children. This evidence of cardiac remodeling was present in obese children as young as age 8. Twenty four percent of obese/overweight children had concentric hypertrophy, 59 % had normal geometry and 17 % had either eccentric hypertrophy or concentric remodeling. LV mass index, thickness, ejection fraction and peak longitudinal and circumferential strains all correlated with epicardial adipose tissue after adjusting for height and gender (all p <0.05). Peak longitudinal and circumferential strains showed a significant relationship with the type of LV remodeling, and were most impaired in children with concentric hypertrophy (p <0.001 and p = 0.003, respectively). CONCLUSIONS Obese children show evidence of significant cardiac remodeling and dysfunction, which begins as young as age 8. Obese children with concentric hypertrophy and impaired strain may represent a particularly high risk subgroup that demands further investigation.

Increased interventricular septum wall thickness predicts all-cause death in patients with coronary artery disease. Intern Med J 2015; 45:275-83. [PMID: 25510963 DOI: 10.1111/imj.12667] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2014] [Accepted: 12/08/2014] [Indexed: 02/05/2023]
Abstract
BACKGROUND There is debate regarding the predictive value of interventricular septum (IVS) wall thickness for adverse events. AIMS The study investigated the association between the severity of thickened IVS and all-cause death in Chinese patients with coronary artery disease (CAD). METHODS A total of 2297 CAD patients verified by angiography was consecutively included. Patients were grouped according to the severity of thickened IVS. Cox regression analysis was conducted to determine the independent prognostic value of thickened IVS for all-cause death. RESULTS During a median follow up of 25 months, 149 patients died. A gradient increase in the risk of death was observed across thickened IVS groups. Compared to patients with normal IVS thickness, the adjusted hazard ratio (HR) was 1.49 (95% confidence interval (CI) 1.00-2.23, P = 0.05) and 2.13 (95% CI 1.29-3.54, P = 0.003) for all-cause death in those with mildly and moderately/severely thickened IVS respectively. For one unit increase in IVS thickness, the risk of all-cause death was elevated by 14% (adjusted HR 1.14, 95% CI 1.05-1.24, P = 0.003). In patients with normal indexed left ventricular mass, thickened IVS was also demonstrated as an independent risk factor for all-cause death. CONCLUSION Thickened IVS can be served as a reliable marker for predicting all-cause death in Chinese patients with CAD, even in those with normal left ventricular mass.

Tomato (Lycopersicon esculentum) Supplementation Induces Changes in Cardiac miRNA Expression, Reduces Oxidative Stress and Left Ventricular Mass, and Improves Diastolic Function. Nutrients 2015; 7:9640-9. [PMID: 26610560 PMCID: PMC4663621 DOI: 10.3390/nu7115493] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2015] [Revised: 10/29/2015] [Accepted: 11/12/2015] [Indexed: 12/14/2022] Open
Abstract
The aim of this study was to evaluate the effects of tomato supplementation on the normal rat heart and the role of oxidative stress in this scenario. Male Wistar rats were assigned to two groups: a control group (C; n = 16), in which animals received a control diet + 0.5 mL of corn oil/kg body weight/day, and a tomato group (T; n = 16), in which animals received a control diet supplemented with tomato +0.5 mL of corn oil/kg body weight/day. After three months, morphological, functional, and biochemical analyses were performed. Animals supplemented with tomato had a smaller left atrium diameter and myocyte cross-sectional area (CSA) compared to the control group (C group: 474 (415–539); T group: 273 (258–297) µm2; p = 0.004). Diastolic function was improved in rats supplemented with tomato. In addition, lipid hydroperoxide was lower (C group: 267 ± 46.7; T group: 219 ± 23.0 nmol/g; p = 0.039) in the myocardium of rats supplemented with tomato. Tomato intake was also associated with up-regulation of miR-107 and miR-486 and down-regulation of miR-350 and miR-872. In conclusion, tomato supplementation induces changes in miRNA expression and reduces oxidative stress. In addition, these alterations may be responsible for CSA reduction and diastolic function improvement.

Abstract
OBJECTIVES Although inappropriate left ventricular mass has been associated with clustered cardiac geometric and functional abnormalities, its predictive value in patients with coronary artery disease is still unknown. This study examined the association of inappropriate left ventricular mass with clinical outcomes in patients with angina pectoris and normal ejection fraction. PARTICIPANTS AND METHODS Consecutive patients diagnosed with angina pectoris whose ejection fraction was normal were recruited from 2008 to 2012. Inappropriate left ventricular mass was determined when the ratio of actual left ventricular mass to the predicted one exceeded 150%. The primary endpoint was a composite of all-cause death, nonfatal myocardial infarction, and nonfatal stroke. Clinical outcomes between the inappropriate and appropriate left ventricular mass group were compared before and after propensity matching. RESULTS Of the total of 1515 participants, 18.3% had inappropriate left ventricular mass. Patients with inappropriate left ventricular mass had a higher composite event rate compared with those with appropriate left ventricular mass (11.2 vs. 6.6%, P=0.010). Multivariate Cox regression analyses showed that inappropriate left ventricular mass was an independent risk factor for adverse events (adjusted hazard ratio, 1.59; 95% confidence interval, 1.03-2.45; P=0.035). The worse outcome in patients with inappropriate left ventricular mass was further validated in a propensity matching cohort and patients with the traditional definition of left ventricular hypertrophy. CONCLUSION Inappropriate left ventricular mass was associated with an increased risk of adverse events in patients with angina pectoris and normal ejection fraction.

Abstract
BACKGROUND Increased left ventricular (LV) size is associated with cardiovascular mortality and morbidity. Once non-contrast cardiac computed tomography (CT) is performed for other purposes, information of LV size is readily available. PURPOSE To determine the association of gated CT-derived LV size with cardiovascular risk factors and coronary artery calcification (CAC) and to describe age- and gender-specific normative values in a general population cohort. MATERIAL AND METHODS LV area was quantified from non-contrast-enhanced CT in axial, end-diastolic images at a mid-ventricular slice in participants of the population-based Heinz Nixdorf Recall Study, free of known cardiovascular disease. LV index (LVI) was calculated by the quotient of LV area and body surface area (BSA). Crude and adjusted regression analyses were used to determine the association of LVI with risk factors and CAC. RESULTS Overall, 3926 subjects (age 59 ± 8 years, 53% women) were included in this analysis. From quantification in end-diastolic phase, men had larger LV index (2232 ± 296 mm(2)/m(2) vs. 2088 ± 251 mm(2)/m(2), both P < 0.0001). LVI was strongly correlated systolic blood pressure (men, PE [95% CI]: 22.8 [15.5-30.2] mm(2)/10 mmHg; women, 23.4 [18.1-28.6]), and antihypertensive medication (men, 45.2 [14.7-75.8] mm(2); women: 46.5 [22.7-70.2], all P < 0.005). Cholesterol levels were associated with LVI in univariate analysis, however, correlations were low (R(2) ≤ 0.04). In multivariable regression, blood pressure, antihypertensive medication and cholesterol levels, remained associated with LVI (P < 0.05). LVI was linked with CAC in unadjusted (men, increase of CAC + 1 by 13.0% [1.4-25.8] with increased LVI by 1 standard deviation of LVI, P = 0.03; women, 20.7% [10.0-32.3], P < 0.0001) and risk factor adjusted models (men, 14.6% [3.7-26.6], P = 0.007); women, 17.4% [7.8-27.8], P = 0.0002). CONCLUSION Non-contrast cardiac CT derived LV index is associated with body size and hypertension. LVI is weakly linked with CAC-score. Further studies need to evaluate whether assessment of LV dimensions from cardiac CT helps identifying subjects with increased cardiovascular risk.

Abstract
BACKGROUND/OBJECTIVES Earlier studies differ on whether serum leptin is associated with adverse or beneficial cardiac structure. We determined the association between serum leptin with subsequent cardiac structure and function. METHODS MESA is a multicenter longitudinal study of Black, White, Hispanic and Asian-American men and women. Cardiac MRI (CMR) was completed 6 to 8 years after leptin was measured. Left ventricular (LV) mass and volumes were indexed to body surface area. Multivariable linear regression models were constructed to assess the associations between leptin and risk factor adjusted (age, race, gender, systolic blood pressure, anti-hypertensive usage, LDL, HDL, hyperlipidemia medication usage, diabetes, diabetic medication usage, chronic kidney disease, alcohol and tobacco use, adiponectin and BMI) CMR variables. RESULTS Relative to participants in the lowest quintile of leptin concentration, participants in the highest quintile had a lower risk factor adjusted LV mass (-14 g), LV mass index (-9 g/m(2)), LV end diastolic volume index (LVEDVi) (-7 ml/m(2)), LV end systolic volume index (LVESVi) (-3 ml/m(2)) and stroke volume (-5 ml) (all p≤0.05). On regression analysis, a doubling of leptin concentration was associated with lower LV mass (-2.5 g ± 0.7 g), LV mass index (-1.7 ± 0.3g/m(2)), LVEDVi (-1.5 ± 0.4 ml/m(2)), LVESVi (-0.7 ± 0.2 ml/m(2)) and stroke volume (-1.0 ± 0.5 ml) (all p ≤ 0.05). CONCLUSIONS Higher leptin was associated with more favorable subsequent cardiac structure. Further study is needed to assess the prognostic and therapeutic implications of these observations.

Abstract
BACKGROUND We sought to assess the association of left ventricle mass (LVM) indices with the functional outcome of acute ischemic stroke (AIS) patients after intravenous tissue plasminogen activator (IV-tPA). METHODS Consecutive AIS patients with IV-tPA were recruited. LVM indices including LVM/weight, LVM/surface, and LVM/heightˆ(2.7) on echocardiogram during hospitalization were retrospectively reviewed. Outcome was 90-day modified Rankin scale (mRS) scores. Multivariate logistic regression was performed to analyze the association of LVM indices with outcome. RESULTS Between August 2010 and May 2014, 55 AIS patients (age range from 27 to 78 years, 69.1% men) with echocardiogram after thrombolysis were recruited. Lower baseline National Institutes of Health Stroke Scale (NIHSS; P = .009) and higher LVM indices (LVM/weight [P = .012], LVM/surface [P = .039], and LVM/heightˆ(2.7) [P = .045]) were significantly associated with 90-day favorable outcome (mRS, 0-2). In multivariate logistic regression analysis, LVM/weight independently predicted good outcome with an odds ratio of 3.89 (95% confidence interval, 1.05-14.42, P = .042) after adjustment for baseline NIHSS, onset-to-treatment time, hypertension, hemorrhagic transformation, and systolic left ventricle inner diameters. CONCLUSIONS Higher LVM indices on echocardiogram are significantly associated with favorable outcome in stroke patients with IV-tPA, among which LVM/weight seems to be the most effective.

Abstract
Hypertension is prevalent in patients with end-stage renal disease and is strongly associated with left ventricular hypertrophy (LVH), an independent predictor of cardiovascular mortality. Blood pressure (BP) monitoring in hemodialysis patients may be unreliable because of its lability and variability. We compared different methods of BP measurement and their relationship with LVH on cardiac magnetic resonance imaging. Sixty patients undergoing chronic hemodialysis at a single dialysis center had BP recorded at each dialysis session over 12 weeks: pre-dialysis, initial dialysis, nadir during dialysis, and post-dialysis. Forty-five of these patients also underwent 44-hour inter-dialytic ambulatory BP monitoring. Left ventricular mass index (LVMI) was measured using cardiac magnetic resonance imaging and the presence of LVH was ascertained. Receiver operator characteristic curves were generated for each BP measurement for predicting LVH. The mean LVMI was 68 g/m(2) (SD = 15 g/m(2)); 13/60 patients (22%) had LVH. Mean arterial pressure measured shortly after initiation of dialysis session was most strongly correlated with LVMI (Pearson correlation coefficient r = 0.59, P < .0001). LVH was best predicted by post-dialysis systolic BP (area under the curve, 0.83; 95% confidence interval, 0.72-0.94) and initial dialysis systolic BP (area under the curve, 0.81; 95% confidence interval, 0.70-0.92). Forty-four-hour ambulatory BP and BP variability did not significantly predict LVH. Initial dialysis mean arterial pressure and systolic BP and post-dialysis systolic BP are the strongest predictors of LVH, and may represent the potentially best treatment targets in hemodialysis patients to prevent end-organ damage. Further studies are needed to confirm whether treatment targeting these BP measurements can optimize cardiovascular outcomes.

Abstract
Cardiovascular magnetic resonance (CMR) is gaining clinical importance in preventive medicine. Evidence on diagnostic accuracy and prognostic value, in addition to the development of faster imaging, increased availability of equipment and imaging expertise have led to a wide-spread use of CMR in a growing number of clinical indications. The first part of this review summarizes the role of CMR biomarkers for risk assessment focusing on the patients groups that benefit from the use of CMR. In the second part, the future directions for CMR are discussed and their role in prevention of cardiovascular disease.

Abstract
Taste ability is known to be impaired in elderly and even more so in acutely hospitalized elderly people. To our knowledge, no study has investigated the association between taste impairment and mortality. Our aim was to examine this association in acutely hospitalized older people. In a prospective study, 200 acutely hospitalized elderly people ≥70 years of age were included between November 2009 and October 2010 at the Oslo University Hospital, Norway. Exclusion criteria were cognitive impairment, nursing home residency, and terminal diseases. Comorbidity was registered with the Cumulative Illness Rating Scale, in addition to recording of age, gender, smoking, education, and number of medications. Taste ability was assessed quantitatively with the "taste strips method" in 174 patients (mean age: 84 years). Mortality until 1 January 2012 was obtained from hospital records. Fifty-six patients died during the observation period. The relative risk of death in total taste score quartile 4 compared with total taste score quartile 1 was 0.31 (95% confidence interval [95% CI]: 0.14-0.69, P = 0.004), after adjusting for age, gender, smoking, education, and Cumulative Illness Rating Scale. Adjusted 1-year mortality decreased from 30% in total taste score quartile 1 to 9% in total taste score quartile 4. Thus, impaired taste appears to be strongly associated with mortality in acutely hospitalized elderly people.

Abstract
Most people believe that being taller and heavier is a sign of higher social status and privilege; however, an objective evaluation of the advantages and disadvantages of increased body size (excluding obesity) indicated that shorter, smaller bodies have numerous advantages in terms of health and longevity. With healthful nutrition and lifestyles, and good medical care, shorter people are less likely to suffer from age-related chronic diseases and more likely to reach advanced ages. A variety of biological factors explain the inherent benefits of smaller bodies. These include reduced cell replication, much lower DNA damage and reduced cancer incidence. Other beneficial factors include higher sex hormone binding globulin, higher insulin-like growth factor binding protein-1, lower insulin and lower insulin-like growth factor-1. We discuss recommendations for how taller people can minimize their risks. Future public health practices should focus on healthful nutrition, without promoting continued secular growth in height and weight.
