Abstract
The cardiac fibroblast interacts with an extracellular matrix (ECM), enabling myofibroblast maturation via a process called mechanosensing. Although in the aging male heart, ECM is stiffer than in the young mouse, myofibroblast development is impaired, as demonstrated in 2-D and 3-D experiments. In old male cardiac fibroblasts, we found a decrease in actin polymerization, α-smooth muscle actin (α-SMA), and Kindlin-2 expressions, the latter an effector of the mechanosensing. When Kindlin-2 levels were manipulated via siRNA interference, young fibroblasts developed an old-like fibroblast phenotype, whereas Kindlin-2 overexpression in old fibroblasts reversed the defective phenotype. Finally, inhibition of overactivated extracellular regulated kinases 1 and 2 (ERK1/2) in the old male fibroblasts rescued actin polymerization and α-SMA expression. Pathological ERK1/2 overactivation was also attenuated by Kindlin-2 overexpression. In contrast, old female cardiac fibroblasts retained an operant mechanosensing pathway. In conclusion, we identified defective components of the Kindlin/ERK/actin/α-SMA mechanosensing axis in aged male fibroblasts.

Abstract
Quercetin is an essential flavonoid mostly found in herbal plants, fruits, and vegetables, which exhibits anti-hypertension properties. However, its pharmacological impact on angiotensin II (Ang II) induced the increase of blood pressure along with in-depth mechanism needs further exploration. The present study pointed out the anti-hypertensive role of quercetin and its comprehensive fundamental mechanisms. Our data showed that quercetin treatment substantially reduced the increase in blood pressure, pulse wave velocity, and aortic thickness of abdominal aorta in Ang II-infused C57BL/6 mice. RNA sequencing revealed that quercetin treatment reversed 464 differentially expressed transcripts in the abdominal aorta of Ang II-infused mice. Moreover, overlapping KEGG-enriched signaling pathways identified multiple common pathways between the comparison of Ang II versus control and Ang II + quercetin versus Ang II. Likewise, these pathways included cell cycle as well as p53 pathways. Transcriptome was further validated by immunohistochemistry, indicating that quercetin treatment significantly decreased the Ang II-induced expression of proliferating cell nuclear antigen (PCNA), cyclin-dependent kinase-4 (CDK4), and cyclin D1, while increased protein expression of p53, and p21 in abdominal aortic tissues of mice. In vitro, quercetin treatment meaningfully decreased the cell viability, arrested cell cycle at G0/G1 phase, and up-regulated the p53 and p21 proteins expression, as well as down-regulated the protein expression of cell cycle-related markers, for example, CDK4, cyclin D1 in Ang II stimulated vascular smooth muscle cells (VSMCs). This study addresses pharmacologic and mechanistic perspectives of quercetin against Ang-II-induced vascular injury and the increase of blood pressure.

Abstract
Calanus oil, an oil extracted from the marine crustacean Calanus finmarchicus, is one of the richest sources of omega-3 and poly-unsaturated fatty acids. Although calanus oil has been shown to have a significant anti-hypertensive, anti-inflammatory, anti-fibrotic and anti-obesity effects in various cardiovascular diseases, but little is known about its effect on pathological cardiac hypertrophy. Thus, the present study was carried out to evaluate the therapeutic effect of calanus oil on cardiac hypertrophy. Cardiac hypertrophy was induced by subcutaneous injections with isoproterenol (5 mg/kg b.w) for 14 consecutive days. Calanus oil (400 mg/kg) was given orally for 4 weeks. Cardiac pathological remodeling was evaluated by echocardiography, after which morphometric, biochemical, histological and ultrastructural analyses were performed. Calanus oil treatment significantly ameliorated isoproterenol-induced structural and functional alterations in echocardiography. Calanus oil also reduced the relative heart weight, significantly decreased the elevated cardiac enzymes (LDH and CK-MB) and the lipid peroxidation marker (MDA), augmented the myocardial antioxidant status (TAC), and ameliorated the histopathological and ultrastructural changes in cardiac tissues and prevented interstitial collagen deposition. The present study, for the first time, provided morphometric, biochemical, histological and ultrastructural evidences supporting the promising anti-hypertrophic effect of calanus oil against ISO-induced cardiac hypertrophy. This anti-hypertrophic effect of calanus oil is via regulating myocardial remodeling and oxidative stress. Therefore, it could be used as potential pharmacological intervention in the management of cardiac hypertrophy.

Abstract
Background Circulating androgen concentrations in men decline with age and have been linked to diabetes and atherosclerotic cardiovascular disease (ASCVD). A similar relationship has been reported for low total testosterone and incident heart failure (HF) but remains unstudied for free testosterone or the more potent androgen dihydrotestosterone (DHT). We hypothesized that total/free testosterone are inversely related, sex hormone–binding globulin is positively related, and total/free DHT bear a U‐shaped relationship with incident HF. Methods and Results In a sample of men from the CHS (Cardiovascular Health Study) without atherosclerotic cardiovascular disease or HF, serum testosterone and DHT concentrations were measured by liquid chromatography–tandem mass spectrometry, and sex hormone–binding globulin by immunoassay. Free testosterone or DHT was calculated from total testosterone or total DHT, sex hormone–binding globulin, and albumin. We used Cox regression to estimate relative risks of HF after adjustment for potential confounders. In 1061 men (aged 76±5 years) followed for a median of 9.6 years, there were 368 HF events. After adjustment, lower calculated free testosterone was significantly associated with higher risk of HF (hazard ratio [HR], 1.14 [95% CI, 1.01–1.28]). Risk estimates for total testosterone (HR, 1.12 [95% CI, 0.99–1.26]), total DHT (HR, 1.10 [95% CI, 0.97–1.24]), calculated free dihydrotestosterone (HR, 1.09 [95% CI, 0.97–1.23]), and sex hormone–binding globulin (HR, 1.07 [95% CI, 0.95–1.21]) were directionally similar but not statistically significant. Conclusions Calculated free testosterone was inversely associated with incident HF, suggesting a contribution of testosterone deficiency to HF incidence among older men. Additional research is necessary to determine whether testosterone replacement therapy might be an effective strategy to lower HF risk in older men.

Abstract
OBJECTIVES This study aimed to evaluate the interactions of ST-elevation myocardial infarction (STEMI), ageing and sex with respect to the incidence of major adverse cardiovascular events (MACE) among Chinese adults. DESIGN Secondary analysis of a single-centre prospective cohort. SETTING Patients who were admitted to cardiology clinics of the Affiliated Hospital of Jiangsu University due to acute myocardial infarction (MI) from June 2017 to November 2019 were eligible for inclusion in the study. This research only examined in-hospital cases. PARTICIPANTS Patients aged <18 years or confirmed dead within 24 hours from admission were excluded. A total of 843 adults were included in the analysis. PRIMARY AND SECONDARY OUTCOME MEASURES MACE was defined as any occurrence of cardiovascular mortality, MI recurrence, cardiogenic shock or heart failure. The relative excess risk due to interaction (RERI), attributable proportion (AP) and the synergy index were computed to quantify the interactions. Men without STEMI and adults without STEMI aged <60 years were the reference groups when examining the risk of MACE. RESULTS The female participants with STEMI showed a statistically higher risk of MACE compared with the male participants without STEMI (relative risk (RR): 2.713, CI: 1.350 to 5.426, p=0.005). A 3.327 times higher risk of MACE was detected in the older adults with STEMI (aged ≥60 years) compared with the adults without STEMI aged <60 years (RR: 3.327, CI: 1.414 to 8.955, p=0.01). Older female patients also had an increased risk of MACE (RR: 3.033, CI: 1.432 to 6.777, p=0.005). A positive additive interaction was detected between STEMI and age (RERI: 1.917, CI: 0.196 to 3.637; AP: 0.576, CI: 0.174 to 0.979). STEMI and sex also indicated an additive interaction (AP: 0.459, CI: 0.018 to 0.899). CONCLUSION In this Chinese population with MI, the risk of MACE was increased by about 2.7 times in women with STEMI compared with men without STEMI. MACE incidence increased by about 3.3 times in older patients with STEMI compared with younger patients without STEMI. STEMI and age, and STEMI and sex, may have a positive additive interaction.

Abstract
AIMS There is much controversy regarding whether cardiovascular events increase in women with polycystic ovary syndrome (PCOS) with aging. Considering the lack of possibility of certain investigations in humans, animal models of PCOS may be suitable resources to obtain the useful data needed. In this study; we aimed to investigate whether cardiac function and tolerance to ischemia/reperfusion (I/R) injury worsen in postmenopausal rats, who had PCOS at younger ages, compared to controls. MAIN METHODS The hearts of aged rats with a history of PCOS and their controls were isolated and perfused in a Langendorff apparatus. Values of hemodynamic parameters, including left ventricular systolic pressure (LVSP), left ventricular developed pressure (LVDP), rate pressure product (RPP) and peak rates of positive and negative changes in left ventricular pressure (±dp/dt) were recorded using a power lab system. Blood serum levels of total testosterone (TT) and estradiol (E2) were determined by ELISA kits. Generalized Estimating Equation Model and t-student unpaired test results were used to compare the findings documented between two groups. KEY FINDINGS No statistically significant differences were observed in hemodynamic parameters of the heart including, LVSP, LVDP, RPP and ±dp/dt, between the rats of two groups of study, at baseline or before ischemia and after I/R. Nor were any significant differences observed in the levels of two hormones between the two groups (p > 0.05). SIGNIFICANCE History of PCOS during reproductive ages should not be considered an important risk factor for reduction in cardiac contractile function or less tolerance to I/R injury during the postmenopausal period.

Abstract
BACKGROUND Hyperglycemia is a major public health concern. An understanding of the latest trends of the global burden of noncommunicable diseases (NCDs) by high fasting plasma glucose (HFPG) is critical for determining research priorities and planning health policy. METHODS This is a comparative burden-of-disease study. We obtained global, regional, and national data on deaths and disability-adjusted life years (DALYs) of NCDs attributable to HFPG from the Global Burden of Disease Study 2017, performed a secondary analysis of deaths and DALYs by time, age, gender, location, and specific causes, and analyzed their associations. RESULTS In 2017, 6.39 million deaths and 166.36 million DALYs from NCDs were attributable to HFPG, accounting for 15.6% and 10.7% of all deaths and DALYs, respectively. The burden's rate decreased with time, increased with age and was significantly higher in males. A negative association was found between the sociodemographic index (SDI) and disease burden, and a positive association was found between SDI and male superiority by gender difference and gender ratio. CONCLUSIONS The burden of NCDs attributable to HFPG has increased significantly since 1990 and varied widely across regions. Greater efforts are needed to prevent and control hyperglycemia, especially in less developed countries and among males.

Lack of sexual dimorphism in a mouse model of isoproterenol-induced cardiac dysfunction. PLoS One 2020; 15:e0232507.

Abstract
Sex-related differences in cardiovascular diseases are highly complex in humans and model-dependent in experimental laboratory animals. The objective of this work was to comprehensively investigate key sex differences in the response to acute and prolonged adrenergic stimulation in C57Bl/6NCrl mice. Cardiac function was assessed by trans-thoracic echocardiography before and after acute adrenergic stimulation (a single sub-cutaneous dose of isoproterenol 10 mg/kg) in 15 weeks old male and female C57Bl/6NCrl mice. Thereafter, prolonged adrenergic stimulation was achieved by sub-cutaneous injections of isoproterenol 10 mg/kg/day for 14 days in male and female mice. Cardiac function and morphometry were assessed by trans-thoracic echocardiography on the 15th day. Thereafter, the mice were euthanized, and the hearts were collected. Histopathological analysis of myocardial tissue was performed after staining with hematoxylin & eosin, Masson's trichrome and MAC-2 antibody. Gene expression of remodeling and fibrotic markers was assessed by real-time PCR. Cardiac function and morphometry were also measured before and after isoproterenol 10 mg/kg/day for 14 days in groups of gonadectomized male and female mice and sham-operated controls. In the current work, there were no statistically significant differences in the positive inotropic and chronotropic effects of isoproterenol between male and female C57Bl/6NCrl. After prolonged adrenergic stimulation, there was similar degree of cardiac dysfunction, cardiac hypertrophy, and myocardial fibrosis in male and female mice. Similarly, prolonged isoproterenol administration induced hypertrophic and fibrotic genes in hearts of male and female mice to the same extent. Intriguingly, gonadectomy of male and female mice did not have a significant impact on isoproterenol-induced cardiac dysfunction as compared to sham-operated animals. The current work demonstrated lack of significant sex-related differences in isoproterenol-induced cardiac hypertrophy, dysfunction, and fibrosis in C57Bl/6NCrl mice. This study suggests that female sex may not be sufficient to protect the heart in this model of isoproterenol-induced cardiac dysfunction and underscores the notion that sexual dimorphism in cardiovascular diseases is highly model-dependent.

Abstract
AIMS Cardiovascular diseases may originate from suboptimal intrauterine environments. We aimed to examine the effects of prenatal androgen exposure (PAE) on heart basal hemodynamic parameters and tolerance to ischemia/reperfusion (I/R) injury, in PAE adult females and males. MAIN METHODS Pregnant Wistar rats in the experimental group (n = 8) received 5 mg of testosterone (s.c. injection) on the 20th day of pregnancy, while controls received solvent. The hearts of adult female and male offspring were isolated and perfused in a Langendorff apparatus, values of left ventricular systolic pressure(LVSP), left ventricular developed pressure(LVDP), rate pressure product(RPP) and peak rates of positive and negative changes in left ventricular pressure(±dp/dt) were recorded using a power lab system. KEY FINDINGS At baseline, PAE adult males demonstrated significant higher values of LVSP, LVDP, RPP and ± dp/dt, compared to controls and PAE adult females (p < 0.05), while PAE adult females showed no significant differences compared to controls. In PAE adult males, LVSP, LVDP, RPP and ± dp/dt had significant decreasing trends per phases after I/R, compared to their controls and PAE females, while these decreasing trends were not statistically significant in PAE adult female rats vs. their controls. SIGNIFICANCE The impact of prenatal androgen exposure on adulthood cardiac function and tolerance to I/R is gender dependent, which may be partly explained by different cardiac effects of hyperandrogenism in males versus females. After prenatal androgen exposure, the baseline hemodynamic parameters of the hearts of adult males are increased; although they had less tolerance to I/R, findings however not observed in females.

Abstract
BACKGROUND Using the normal values for the East Asian population, we evaluated age- and body size-adjusted left ventricular end-diastolic dimension (LVEDD) and its prognostic impact in a hospital-based population in Japan. Methods and Results: We retrospectively analyzed data obtained from 4,444 consecutive patients who had undergone both transthoracic echocardiography and electrocardiography at Kitano Hospital in 2013. Those who presented with a history of previous episodes of myocardial infarction and severe or moderate valvular disease or with low ejection fraction (<50%) were excluded from the analysis. We calculated LVEDD adjusted by age and body surface area. A total of 3,474 patients were categorized into 3 groups: 401 with large adjusted LVEDD, 2,829 with normal adjusted LVEDD, and 244 with small adjusted LVEDD. Mean patient age in the large, normal, and small adjusted LVEDD groups was 66.6±18.4, 65.6±15.7, and 62.1±15.5 years, respectively (P<0.001). After adjusting for confounding factors, the excess adjusted 3-year risk of primary outcome of large adjusted LVEDD relative to normal LVEDD was significant (HR, 1.40; 95% CI: 1.08-1.78). The risk for primary outcomes of small adjusted LVEDD relative to normal adjusted LVEDD was significantly lower (HR, 0.55; 95% CI: 0.34-0.85). CONCLUSIONS Adjusted large LVEDD has a deleterious impact on long-term mortality, whereas small LVEDD carried a significantly lower risk.

Abstract
The recognition of cardiovascular disease (CVD) as a "male" privilege has been a commonly held concept. However, emerging data describe another reality. Heterogeneities have been convincingly demonstrated regarding CVD manifestations, risk factor burden, and prognosis between males and females. The aim of the present narrative review was to highlight sex- and gender-related discrepancies in primary and secondary CVD prevention, underscoring plausible underlying mechanisms. Manifestation of CVD in women is characterized by atypical symptoms/signs and inadequately studied pathophysiology features challenging accurate diagnosis and effective treatment. Regarding CVD risk assessment, the burden and effect size of conventional, novel, and female-specific risk factors needs better clarification. Hitherto outcomes are nonconsistent, while most importantly, the interpretation of the attendant metabolic paths remains a challenge; the interactions among genetic, metabolic, and environmental factors are of high complexity regulated by genomic and nongenomic sex hormones effects. To deal with these key points, the National Institutes of Health currently calls upon investigators to provide a sex- and gender-specific reporting in all health research hypotheses. The implementation of high-quality studies addressing these issues is an imperative need to maximize cost-effectiveness in prevention and management strategies.

Abstract
Recent advances in cardiac imaging techniques have substantially contributed to a growing interest in the analysis of global cardiac chamber dimensions and regional myocardial deformation. During the cardiac cycle, ventricular luminal volume varies due to the contraction process, which also confers a shape change including substantial alteration of long axis length, as well as rotation of the base compared to the apex. Local deformation can be assessed by strain (rate) analysis. Reviewing the present literature, it must be concluded that there is no single metric available to comprehensively characterize ventricular function. Every candidate advanced thus far has been found to incompletely reflect ventricular performance. This observation is not surprising in view of the complexity of the cardiac pump system. Additionally, sex-specific modifiers may play a role. More than three decades ago, it was shown that on average the ventricular volume is smaller in healthy women compared to matched males. Therefore, the present contribution concerns the interpretation of data derived from the healthy heart in both men and women. Starting from the classical Starling concept, we apply a simple mathematical transformation which permits an insightful representation of ventricular mechanics. Relating end-systolic volume (ESV) to end-diastolic volume creates the ventricular volume regulation graph which features the pertinent working point of an individual heart. This fundamental approach illustrates why certain proposed performance indexes cannot individually reveal the essence of ventricular systolic function. We demonstrate that particular metrics are highly interconnected and just tell us the same story in a different disguise. It is imperative to understand which associations exist and if they expectedly are (nearly) linear or frankly nonlinear. Notably, ejection fraction (EF) is primarily determined by ESV, while in turn EF is not much different from ventriculo-arterial coupling (VAC). Insight into cardiac function is promoted by identification of the paramount/essential components involved. The smaller ESV (p < 0.0001) implies that EF is higher in women and may also have consequences for VAC.

Abstract
OBJECTIVES In congestive heart failure (CHF), men are younger, more likely to have reduced ejection fraction (HF-rEF), and to be diabetic compared to women. Despite this, sex differences in oxidative stress have yet to be explored in CHF. METHODS Data from 67 males and 63 females hospitalized for CHF were collected. Static oxidation-reduction potential (sORP), a relative indicator of oxidative stress, and capacity ORP (icORP), a relative indicator of antioxidant capacity, were measured from plasma samples. We examined whether sex modified the relationship between ORP and hospital discharge disposition (poor outcome: death, hospice), along with other demographics, medications, and diagnostic parameters. RESULTS Males with poor outcomes had higher sORP and icORP values than females (P < 0.05). For those with a good outcome, there were no differences between the sexes (P > 0.05). Males were younger and more likely to have HF-rEF and diabetes. Controlling for these variables did not account for the sex differences in ORP measures. Regardless of sex, higher creatinine was related to higher sORP and icORP, while lower magnesium and potassium were related to higher sORP and icORP, respectively. DISCUSSION Increases in sORP during CHF are partially affected by sex and acute outcomes, but are also related to variables without sexual biases.

Abstract
Objective To elucidate the factors associated with high left ventricular mass index (LVMI) and to test the hypothesis that high LVMI is associated with worse outcome in severe aortic stenosis (AS). Methods We analysed 3282 patients with LVMI data in a retrospective multicentre registry enrolling consecutive patients with severe AS in Japan. The management strategy, conservative or initial aortic valve replacement (AVR), was decided by the attending physician. High LVMI was defined as LVMI >115 g/m2 for males and >95 g/m2 for females. We compared the risk between normal and high LVMI in the primary outcome measures compromising aortic valve-related death and heart failure hospitalisation. Results Age was mean 77 (SD 9.6) years and peak aortic jet velocity (Vmax) was 4.1 (0.9) m/s. The factors associated with high LVMI (n=2374) included female, body mass index ≥22, absence of dyslipidemia, left ventricular ejection fraction <50%, Vmax ≥4 m/s, regurgitant valvular disease, hypertension, anaemia and end-stage renal disease. In the conservative management cohort (normal LVMI: n=691, high LVMI: n=1480), the excess adjusted 5-year risk of high LVMI was significant (HR: 1.53, 95% CI 1.26 to 1.85, p<0.001). In the initial AVR cohort (normal LVMI: n=217, high LVMI: n=894), the risk did not differ significantly between the two groups (HR: 0.96, 95% CI 0.60 to 1.55, p=0.88). There was a significant interaction between the initial treatment strategy and the risk of high LVMI (p=0.016). Conclusions The deleterious impact of high LVMI on outcome was observed in patients managed conservatively, but not observed in patients managed with initial AVR. Trial registration number UMIN000012140; Post-results.

Abstract
OBJECTIVES Menopause and diabetes obviously increase the risk of cardiovascular disease in women. The aims of the present study were to evaluate the effects of ovariectomy in type 2 diabetes on the histology and expression of miRNA-29, miRNA-133, IGF-1 and Bcl-2 genes and Bcl-2 protein and caspase 3 activity in the hearts of female rats. MATERIALS AND METHODS Forty Female Wistar rats were divided into four groups: control, sham, ovariectomized (OVX), and ovariectomized with type 2 diabetes (OVX.D). After the 8-week experiment, the histological evaluation of the heart tissue was performed using H&E staining and PAS analysis, and cardiac expression of miRNA-29, miRNA-133, IGF-1, and Bcl-2 were evaluated using real-time PCR, and Bcl-2 protein and caspase 3 activity were evaluated using Western blot and ELISA. RESULTS Ovariectomy significantly decreased miRNA-29, miRNA-133, IGF-1, and BCL-2 expression and Bcl-2 protein and increased caspase 3 activity in the heart compared to sham animals group (P<0.05). Type 2 diabetes in ovariectomized rats markedly decreased expression of miRNA-29, miRNA-133, IGF-1, BCL-2 genes, and Bcl-2 protein, and increased caspase 3 activity and reduced collagen and fibroblast tissue and glycogen granule deposition in relation to OVX group (P<0.05). CONCLUSION Our findings suggest that type 2 diabetes and menopause synergically could enhance the cardiac fibrosis through dysregulation of miRNA-29, miRNA-133, IGF-1, and Bcl-2 genes expression and Bcl-2 protein and upregulation of caspase 3 activity.

Abstract
BACKGROUND In several intervention trials, a healthy Nordic diet showed beneficial effects on markers of cardiovascular disease. We investigated the association between a healthy Nordic diet and clinical diagnosis of cardiovascular disease. OBJECTIVE Our aim was first to examine the association between a healthy Nordic food index (wholegrain bread, oatmeal, apples/pears, root vegetables, cabbages and fish) and the incidence of overall cardiovascular disease (ischaemic heart disease, stroke, arrhythmia, thrombosis and hypertensive disease), and secondly to test for possible effect modification by smoking, body mass index (BMI), alcohol consumption and age. METHODS We conducted an analysis of data from the prospective Swedish Women's Lifestyle and Health cohort, including 43 310 women who completed a food frequency questionnaire in 1991-1992, and followed up until 31 December 2012 through Swedish registries. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. RESULTS During follow-up, 8383 women developed cardiovascular disease. We found no association between the healthy Nordic food index and overall cardiovascular disease risk or any of the subgroups investigated. There was a statistically significant interaction with smoking status (P = 0.02), with a beneficial effect only amongst former smokers (HR 0.96, 95% CI 0.94-0.99 per 1-point increment). CONCLUSION The present results do not support an association between a healthy Nordic food index and risk of cardiovascular disease in Swedish women. There was also no effect modification by alcohol intake, BMI or age. Our finding of an interaction with smoking status requires reproduction.

Abstract
BACKGROUND It is well-documented that persistent myocardial hypertrophy in patients with aortic stenosis is related to suboptimal postoperative outcomes after aortic valve replacement. Although diabetes is known to potentially exacerbate myocardial hypertrophy, it has yet to be examined if it affects postoperative left ventricular mass regression (LVMR). METHODS A single-centre, retrospective analysis was performed on 183 consecutive patients who underwent either surgical or transcatheter aortic valve replacement between 2010 and May 2013. Patient demographics, postoperative outcomes and echocardiographic data were obtained preoperatively and a year after surgery. RESULTS There were 42 diabetic and 141 non-diabetic patients. Preoperative characteristics of diabetic patients were statistically similar to those of non-diabetic patients, except for higher prevalence of hyperlipidaemia (p <0.001) and history of cerebrovascular disorder (p=0.046) in diabetic patients. Median value of postoperative LVMR of all patients was -36.5 g/m(2), and was significantly greater in the non-diabetics compared to the diabetics (-39.1 vs. -22.2 g/m(2), p=0.008). Univariate and multivariate analyses were performed on preoperative variables, and stepwise multiple regression analysis demonstrated that diabetes (standardised partial regression coefficient (SPRC)=-0.187, p=0.018), female gender (SPRC=0.245, p=0.026) and age (SPRC=0.203, p=0.018) were associated with poor postoperative LVMR. CONCLUSIONS Patients with diabetes showed suboptimal postoperative LVMR, and the disease was a prognostic factor that was associated with poor LVMR. These findings suggest that diabetes may predispose the particular group of patients to worse postoperative outcomes.

Abstract
OBJECTIVE Emerging evidence suggests female type 2 diabetes (T2DM) patients may fare worse than males with respect to cardiovascular complications. Hence the impact of sex on relative progression of left ventricular (LV) remodeling in obese db/db mice was characterized. METHODS The changes in parameters of LV hypertrophy (heart weight, pro-hypertrophic gene expression, cardiomyocyte size) and fibrosis (LV collagen deposition and oxidative stress), in parallel with body weight and blood glucose and lipid profiles, in male and female db/db T2DM mice, at 10, 14, and 18 weeks of age, were determined. RESULTS Diabesity-induced cardiac remodeling was at least comparable in female (compared to male) mice. Females exhibited enhanced systemic oxidative stress and nonesterified fatty acid levels. Progression of LV pro-hypertrophic (β-myosin heavy chain, B-type natriuretic peptide) and pro-oxidant gene expression (NADPH oxidase subunit Nox2, plasminogen activator inhibitor-1 PAI-I) was, however, exaggerated in females when expressed relative to 10-week-old db/db mice. Increased cardiomyocyte width was also evident earlier in db/db females than males. No other gender differences were observed. CONCLUSIONS Progressive, age-dependent development of cardiac remodeling in db/db mice parallels impairments in glucose handling and oxidative stress. Certain aspects of the T2DM-induced LV remodeling response may have an earlier and/or exaggerated onset in diabetic females.
