Using rat models of heart failure, we evaluated the effects of rosuvastatin and Huangqi granule alone and in combination on left ventricular end-diastolic dimension, left ventricular end-systolic dimension, left ventricular ejection fraction, left ventricular posterior wall thickness at end-diastole, and left ventricular posterior wall thickness at end-systole. Results showed that left ventricular end-diastolic dimension, left ventricular end-systolic dimension in the rosuvastatin + Huangqi granule group were significantly decreased (P ‹ 0.01), while left ventricular ejection fraction, left ventricular posterior wall thickness at end-diastole and left ventricular posterior wall thickness at end-systole were significantly increased (P ‹ 0.05). The serum IL-2, IFN-β, and TNF-α in rosuvastatin + Huangqi granule group were significantly lower than those in model group (P ‹ 0.05). However, the levels of S-methylglutathione and superoxide dismutase in rosuvastatin + Huangqi granule group were significantly higher, while nitric oxide was significantly lower than that in the model group (P ‹ 0.05). Also, compared to the model group, the apoptosis rate, and the autophagy protein LC3-II in the cardiomyocytes of rosuvastatin + Huangqi granule group was significantly decreased (P ‹ 0.01), while the level of p62 protein was significantly increased (P ‹ 0.01). The levels of AMPK and p-AMPK in cardiomyocytes were significantly lower in rosuvastatin + Huangqi granule group; however, the levels of mTOR and p-mTOR showed an opposite trend (P ‹ 0.05). To sum up, rosuvastatin + Huangqi granule could improve the cardiac function, decrease the level of oxidative stress, and inflammatory cytokines in rats with HF. The possible underlying mechanism might be inhibition of autophagy and reduced apoptosis in cardiomyocytes by regulating AMPK-mTOR signaling pathway.

Surgical Myectomy

Abstract Introduction Alcohol septal ablation (PTSMA) was introduced as interventional alternative to surgical myectomy for symptomatic patients with hypertrophic obstructive cardiomyopathy (HOCM) 25 years ago. As gender differences in diagnosis and treatment of HOCM are still unclear we analyzed baseline characteristics and results of PTSMA in a large single center cohort with respect to gender. Methods and results Between 05/2000 and 06/2017 first PTSMA in our center was performed in 952 patients with symptomatic HOCM. We treated less 388 (40.8%) women and 564 (59.2%) men. All patients underwent clinical follow-up. At the time of the intervention women were older (61.2±14.9 vs. 51.9±13.7 years; p<0.0001) and suffered more often from NYHA grade III/IV dyspnea (80.9% vs. 68.1%; p<0.0001), whereas angina pectoris was comparable in women (62.4%) and men (59.9%). Echocardiographic baseline gradients were comparable in women (rest 65.0±38.1 mmHg and Valsalva 106.2±45.7 mmHg) and men (rest 63.1±38.3 mmHg and Valsalva 103.6±42.8 mmHg). But, women had smaller diameters of the left atrium (44.3±6.9 vs. 47.2±6.5 mm; p<0001), maximal septum thickness (20.4±3.9 vs. 21.4±4.5 mm; p<0.01), and maximal thickness of the left ventricular posterior wall (12.7±2.8 vs. 13.5±2.9 mm; p<0.0001). In women, more septal branches (1.3±0.6 vs. 1.2±0.5; p<0.05) had to be tested to identify the target septal branch. The amount of injected alcohol was comparable (2.0±0, 4 in women vs. 2.1±0.4 ml in men). The maximum CK increase was lower in women (826.0±489.6 vs. 903.4±543.0 U / l; p<0.05). During hospital stay one woman and one man died, each (n.s.). The frequency of total AV blocks in the cathlab showed no significant difference between women (41.5%) and men (38.3%). Furthermore, the rate of permanent pacemaker implantation during hospital stay did not differ (12.1% in women vs. 9.4% in men). Follow-up periods of all patients showed no significant difference between women (5.7±4.9 years) and men (6.2±5.0 years). Overall, 37 (9.5%) women died during this period compared to only 33 (5.9%) men (p<0.05). But, cardiovascular causes of death were not significantly different between women (2.8%) and men (1.6%). Furthermore, the rates of surgical myectomy after failed PTSMA (1.3% in women vs. 2.3% in men), ICD implantation for primary prevention of sudden cardiac death according to current guidelines (4.1% in women vs. 5.9% in men) or pacemaker implantation (3.6% in women vs. 2.0% in men) showed no significant differences. Summary PTSMA in women with HOCM was performed at more advanced age with more pronounced symptoms compared to men. While there were no differences in acute outcomes, overall long-term mortality was higher in women without differences in cardiovascular mortality. Therefore, women may require more intensive diagnostic approaches in order not to miss the correct time for gradient reduction treatment. Funding Acknowledgement Type of funding source: None

Survivors of extremely preterm birth (gestational age < 27 weeks) have been reported to exhibit an altered cardiovascular phenotype in childhood. The mechanisms are unknown. We investigated associations between postnatal nutritional intakes and hyperglycemia, and left heart and aortic dimensions in children born extremely preterm. Postnatal nutritional data and echocardiographic dimensions at 6.5 years of age were extracted from a sub-cohort of the Extremely Preterm Infants in Sweden Study (EXPRESS; children born extremely preterm between 2004–2007, n = 171, mean (SD) birth weight = 784 (165) grams). Associations between macronutrient intakes or number of days with hyperglycemia (blood glucose > 8 mmol/L) in the neonatal period (exposure) and left heart and aortic dimensions at follow-up (outcome) were investigated. Neonatal protein intake was not associated with the outcomes, whereas higher lipid intake was significantly associated with larger aortic root diameter (B = 0.040, p = 0.009). Higher neonatal carbohydrate intake was associated with smaller aorta annulus diameter (B = −0.016, p = 0.008). Longer exposure to neonatal hyperglycemia was associated with increased thickness of the left ventricular posterior wall (B = 0.004, p = 0.008) and interventricular septum (B = 0.004, p = 0.010). The findings in this study indicate that postnatal nutrition and hyperglycemia may play a role in some but not all long-lasting developmental adaptations of the cardiovascular system in children born extremely preterm.

Increased oxidative stress is a known cause of cardiac dysfunction in animals and patients with diabetes, but the sources of reactive oxygen species [e.g., superoxide anion (O2−)] and the mechanisms underlying O2− production in diabetic hearts are not clearly understood. Our aim was to determine whether NADPH oxidase (Nox) is a source of O2− and whether glucose-6-phosphate dehydrogenase (G6PD)-derived NADPH plays a role in augmenting O2− generation in diabetes. We assessed cardiac function, Nox and G6PD activities, NADPH levels, and the activities of antioxidant enzymes in heart homogenates from young (9–11 wk old) Zucker lean and obese (fa/fa) rats. We found that myocardial G6PD activity was significantly higher in fa/fa than in lean rats, whereas superoxide dismutase and glutathione peroxidase activities were decreased ( P < 0.05). O2− levels were elevated (70–90%; P < 0.05) in the diabetic heart, and this elevation was blocked by the Nox inhibitor gp-91ds-tat (50 μM) or by the mitochondrial respiratory chain inhibitors antimycin (10 μM) and rotenone (50 μM). Inhibition of G6PD by 6-aminonicotinamide (5 mM) and dihydroepiandrosterone (100 μM) also reduced ( P < 0.05) O2− production. Notably, the activities of Nox and G6PD in the fa/fa rat heart were inhibited by chelerythrine, a protein kinase C inhibitor. Although we detected no changes in stroke volume, cardiac output, or ejection fraction, left ventricular diameter was slightly increased during diastole and systole, and left ventricular posterior wall thickness was decreased during systole ( P < 0.05) in Zucker fa/fa rats. Our findings suggest that in a model of severe hyperlipidema and hyperglycemia Nox-derived O2− generation in the myocardium is fueled by elevated levels of G6PD-derived NADPH. Similar mechanisms were found to activate O2− production and induce endothelial dysfunction in aorta. Thus G6PD may be a useful therapeutic target for treating the cardiovascular disease associated with type 2 diabetes, if second-generation drugs specifically reducing the activity of G6PD to near normal levels are developed.

Gh Replacement

ObjectiveGH replacement therapy (GHRT) in adult-onset GH deficiency (AOGHD) reduces carotid intima-media thickness (IMT) and increases myocardial mass, with improvement of systolic and diastolic function. These observations have reinforced the use of GHRT on AOGHD. Conversely, we have previously reported that in adults with lifetime congenital and severe isolated GH deficiency (IGHD) due to a mutation in GHRH receptor gene (GHRHR), a 6-month treatment with depot GH increased carotid IMT, caused the development of atherosclerotic plaques, and an increase in left ventricular mass index (LVMI), posterior wall, and septal thickness and ejection fraction. Such effects persisted 12 months after treatment (12-month washout – 12mo).MethodsWe have studied the cardiovascular status (by echocardiography and carotid ultrasonography) of these subjects 60 months after completion of therapy (60-month washout – 60mo).ResultsCarotid IMT reduced significantly from 12 to 60mo, returning to baseline (pre-therapy) value. The number of individuals with plaques was similar at 12 and 60mo, remaining higher than pre-therapy. LVMI, relative posterior wall thickness, and septum thickness did not change between 12 and 60mo, but absolute posterior wall increased from 12 to 60mo. Systolic function, evaluated by ejection fraction and shortening fraction, was reduced at 60mo in comparison with 12mo returning to baseline levels. The E/A wave ratio (expression of diastolic function) decreased at 60mo compared with both 12mo and baseline.ConclusionsIn adults with lifetime congenital IGHD, the increase in carotid IMT elicited by GHRT was transitory and returned to baseline 5 years after therapy discontinuation. Despite this, the number of subjects with plaques remained stable at 60mo and higher than at baseline.

The aim of this study was to estimate the impact and prevalence of left ventricular geometric alterations and systolic and diastolic dysfunction in hemodialysis patients, as well as the relationship with cardiac troponin as a marker of myocardial damage. Methods: 31 patients (pts), 19 males and 12 females, age 58.1±16.4 (26 on hemodialysis, 5 on peritoneal dialysis) and 31 healthy normal controls were enrolled. Echocardiography measurements were carried out according to the American Society of Echocardiography recommendations. Left ventricular mass was calculated, according to the Devereux formula and indexed to height and weight 2.7. Doppler echocardiography was performed to study diastolic function by measurements of isovolumetric relaxation period (IVRT), E wave deceleretion time (DTE) and E/A ratio. Cardiac troponin was measured by a third generation electrochemiluminescence immunoassay. Statistical analysis was performed using the t-test for between-group comparisons and the Pearson and Spearman’s tests to investigate correlations; p values of &lt;0.05 were considered statistically significant. Results: Eccentric hypertrophy was the most frequent pattern (n=17; 55%), followed by normal cardiac geometry (n=7; 23%), and concentric hypertrophy (n=5; 16%). Only 6% of pts (n=2) showed concentric remodelling. Systolic dysfunction was present in terms of endocardial parameters in 3 pts (9%) (fractional shartening &lt;25%, EF&lt;50%), but in terms of midwall myocardial shortening in 51% (n=16). Diastolic dysfunction was present in 87% (n=27) with a pattern of impaired relaxation (in 5 without left ventricular hypertrophy). E/A was negatively correlated with age (r=-0.41, p=0.02); DTE was positively correlated with posterior wall thickness (r=0.36, p=0.05) and interventricular septum thickness (r=0.45, p=0.01); cardiac troponin was positively correlated with age (r=0.50, p=0.00), left ventricular mass (r=0.41, p=0.02), posterior wall thickness (r=0.41; p=0.02) and interventricular septum thickness (r=0.39, p=0.03) but not with diastolic dysfunction parameters. No significant difference was found in terms of duration of dialysis between patients with normal left ventricular geometry and those with left ventricular hypertrophy, but a significant difference in age was found (p=0.03). Pts with diastolic dysfunction had more frequent hypotensive episodes during dialysis (p &lt;0.01). Conclusion: Impaired geometry and cardiac function is frequently observed in pts undergoing hemodialysis. Diastolic dysfuction is associated to a geometric pattern of left ventricular hypetrophy, although it can be an isolated initial manifestation of myocardial damage. Depressed midwall myocardial shortening can discriminate left ventricular dysfunction better than traditional endocardial systolic indexes.

We compared the physical growth, nutritional status, and echocardiographic findings in children aged 3-7 years with Down syndrome who had no congenital heart disease. Thirty such patients who consecutively referred to the Division of Cardiology, Department of Child Health, Medical School, University of Indonesia/Cipto Mangunkusumo Hospital, Jakarta, were compared with sex and age matched controls consisted of normal children attending the Department. It appears that growth and nutritional status of children with Down syndrome tended to be retarded when compared to those of the controls. However, no significant difference were found on the M-mode echocardiographic values of the left ventricle, except that the left ventricular posterior wall thickness in study subjects was more that that of the controls. We concluded that although the pulmonary architecture of patients with Down syndrome is thought to be less developed than that of normal children, it does not affect the left ventricular measurements and function as measured by M-mode echocardiography.

It remains debated whether pulse pressure is associated with left ventricular traits and adverse outcomes over and beyond mean arterial pressure (MAP) in patients with heart failure (HF) with preserved ejection fraction. We investigated these associations in 3428 patients with HF with preserved ejection fraction (51.5% women; mean age, 68.6 years) enrolled in the TOPCAT trial (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist). We computed association sizes and hazards ratios with 1-SD increase in MAP and pulse pressure. In multivariable-adjusted analyses, association sizes ( P ≤0.039) for MAP were 0.016 cm and 0.014 cm for septal and posterior wall thickness, −0.15 for E/A ratio, −0.66 for E/e′, and −0.64% for ejection fraction, independent of pulse pressure. With adjustment additionally applied for MAP, E/A ratio and longitudinal strain increased with higher pulse pressure with association sizes amounting to 0.067 ( P =0.026) and 0.40% ( P =0.023). In multivariable-adjusted analyses of both placebo and spironolactone groups, lower MAP and higher pulse pressure predicted the primary composite end point ( P ≤0.028) and hospitalized HF ( P ≤0.002), whereas MAP was also significantly associated with total mortality ( P ≤0.007). Sensitivity analyses stratified by sex, median age, and region generated confirmatory results with exception for the association of adverse outcomes with pulse pressure in patients with age ≥69 years. In conclusion, the clinical application of MAP and pulse pressure may refine risk estimates in patients with HF with preserved ejection fraction. This finding may help further investigation for the development of HF with preserved ejection fraction preventive strategies targeting pulsatility and blood pressure control.
