OBJECTIVE: The study aims at assessing the relationship between blood pressure, heart geometry parameters, and the erythrocyte content of sulfur, potassium, chlorine and phosphorus, in a group of patients with laboratory systolic and diastolic blood pressure (SBP, DBP) below 140 or 90 mm Hg, respectively, who were otherwise healthy and untreated. METHODS: The study group consisted of 42 adults recruited in a primary care setting. The individuals were healthy, not undergoing any therapy and free from smoking. For each individual, data were obtained on: average 24-hour SBP and DBP, left ventricle geometry, complete blood count, lipids profile, fibrinogen, hs-CRP and the erythrocyte concentration of sulfur (S), potassium (K), chlorine (Cl) and phosphorus (P). RESULTS: Multivariate regression analysis showed statistically significant relationships of diastolic posterior wall thickness (PWTd) and relative wall thickness (RWT) with the concentration ratio of sulfur and potassium (S/K) in erythrocytes: PWTd and RWT increase as the S/K ratio increases. Also, SBP was found to be positively correlated with the S/K ratio. CONCLUSIONS: The increase in sulfur content in RBCs could be an indicator of the downregulation of nitric oxide (NO) erythrocyte bioavailability exerted by endogenously produced hydrogen sulfide (H2S), and, in consequence, a marker of the development of hypertension and/or adverse changes in heart geometry.

Group 2

1. Changes in left ventricular structure and function were assessed by echocardiography in 22 patients before and after 9 months blood pressure control. 2. Nine patients had normal baseline echocardiograms (group 1) and 13 had echocardiographic evidence of left ventricular hypertrophy (group 2). 3. Group 2 patients demonstrated significant reductions in posterior wall thickness (P<0.01), septal wall thickness (P<0.025) and left ventricular mass (P<0.005). Only six of the 13 patients showed a reduction of ≥3 mm in posterior wall thickness. The remainder showed no alteration or only a slight non-significant reduction. 4. The regression of voltage in some patients but not in others did not appear to be related to initial blood pressure, the extent of the fall in blood pressure or duration of follow-up. It was not possible to say whether any specific therapy was beneficial to regression since most of the patients were on multiple therapy.

Echocardiographic Findings

Background Abnormalities in left ventricular (LV) structure and function are prevalent in patients on peritoneal dialysis (PD). The risk of cardiovascular mortality is also 10 – 20 times higher in PD patients than in age- and gender-matched healthy control subjects. Methods Echocardiography was performed annually or every 6 months for children on PD; the frequency was increased if the patient had hypertension or any heart problem. We retrospectively reviewed echocardiographic findings of these children (since February 2005) by chart review. The linear regression analysis of log(B-type natriuretic peptide, BNP) was performed to evaluate the association between serum BNP and cardiac parameters on echocardiography. Results We enrolled 52 patients and evaluated 169 echocardiographic findings in association with serum BNP levels. Systolic blood pressure (adjusted R2 = 0.321), diastolic blood pressure (adjusted R2 = 0.292), LV posterior wall thickness at diastole (0.058), LV posterior wall thickness at systole (0.038), LV internal diameter at diastole (0.177), LV internal diameter at systole (0.132), LV mass index (0.122), thickness of interventricular septum at diastole (0.035), the left atrial (LA) diameter (0.201), LA/aorta diameter ratio (0.113), lateral E/E’ (0.229), and lateral A'/E’ (0.149) showed positive correlation with log(BNP); conversely, LV fractional shortening (FS) (0.065), LV ejection fraction (0.082), right ventricular internal diameter at diastole (0.184), right ventricular fractional shortening (0.754), lateral S’ (0.179), and lateral E’ (0.161) showed negative correlation with log(BNP). Conclusions Routine measurement of serum BNP is recommended in children on PD to evaluate the risk of morphological and functional cardiac problems.

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.

Background Obesity causes cardiovascular disturbances. Theincidence of cardiovascular disease is higher even in mildly obesepatients than in lean subjects.Objectives The purpose of this study was to compare left ven-tricular (LV) mass, LV internal dimensions, and LV systolic func-tion between obese and normal children; and to determine the as-sociation of the degree of obesity with LV mass and LV systolicfunction.Methods This cross-sectional study was conducted on elemen-tary school students in Jakarta from February to April 2003. Wemeasured the subjects’ body weight and height, and performedlipid profile and echocardiography examinations. Measurementsof LV mass, LV internal dimensions with regard to septum thick-ness, LV internal diameter, and LV posterior wall thickness; andLV systolic function as indicated by shortening fraction and ejec-tion fraction, were performed echocardiographically. The differ-ences in measurements between obese and normal children aswell as between obese children with and without lipid abnormalitywere analyzed. The correlation between the degree of obesity withLV size and systolic function was determined.Results Twenty-eight normal children and 62 obese children wereenrolled in the study. Mean LV mass was 35.7 (SD 5.16) g/cm 3 inobese children versus 24.0 (SD 3.80) g/cm 3 in normal children(P<0.0001). Mean septum thickness was 0.8 (SD 0.14) mm inobese children versus 0.6 (SD 7.90) mm in normal children (P<0.0001). Mean posterior wall thickness was 0.9 (SD 0.14) mm inobese children versus 0.6 (SD 9.97) mm in normal children(P<0.0001). Mean LV internal diameter was 4.0 (SD 0.34) mm inobese children versus 3.9 (SD 0.29) mm in normal children(P=0.300). There was strong correlation between the degree ofobesity and LV mass (r=0.838, P<0.0001). LV systolic function(shortening fraction) was 37.1 (SD 4.20) percent in obese childrenversus 35.8 (SD 4.99) percent in normal children (P=0.19). Ejec-tion fraction was 67.4 (SD 5.32) percent in obese children versus65.5 (SD 6.29) percent in normal children (P=0.13). There wasweak correlation between LV systolic function and the degree ofobesity (shortening fraction r=0.219, P=0.038; ejection fractionr=0.239, P=0.023).Conclusions Obese children had significantly greater LV mass,septum thickness, and posterior wall thickness than normal chil-Backgrounddren. Such significant difference was absent for LV internal diam-eter and measures of LV systolic function. There was no signifi-cant difference in LV mass and LV systolic function between obesechildren with or without abnormality of lipid profile. A strong corre-lation exists between the degree of obesity and LV mass, but thecorrelation between degree of obesity and LV systolic function wasweak

Cardiovascular Morbidity And Mortality

Background: The Quilmes community includes 2,400 inhabitants of the middle and high mountains of Tucumán (1,800 to 4,000 meters above sea level). The purpose of the present study was to know their cardiovascular health status. Methods: A cross-sectional descriptive quantitative investigation was carried out in people belonging to the Quilmes community who voluntarily attended the planned evaluation on September 27-29, 2018. Results: Two hundred and two settlers were studied (125 women and 77 men; 48±1.4 years), 23% of them had hypertension (HTN); 14% were smokers; 4.9% had diabetes; 18% had dyslipidemia (DLP) and 25% usually consumed alcohol (1.0 ± 0.4 L/day). Also, 29% were overweight and 36% obese. High blood pressure (BP) was recorded in 48 individuals at the time of the study. Blood pressure decreased in the third compared to the first measurement, whereas heart rate increased in the third assessment (74±1 beats per minute vs. 77±1; p <0.01). Oxygen saturation (95.0±0.2%) was negatively correlated with age (Pearson r: -0.266; p <0.001). In individuals with normal BP, ultrasound E/ratio was higher (1.2±0.0) and left ventricular posterior wall thickness was lower (8.5±0.5 mm) than in those with elevated BP (0.92±0.1 and 9.0±0.3, respectively, p <0.001). Twenty-four percent of individuals had atherosclerotic plaques and 120 had DLP. Conclusions: The Quilmes population presents a prevalence of cardiovascular risk factors similar to that of urban centers, which could lead to an increase in cardiovascular morbidity and mortality in the coming years

1. A comparison of direct measurement and M-mode echocardiography in the determination of posterior left ventricular wall thickness was performed in 26 subjects, of whom 21 underwent cardiac bypass surgery; the remainder came to necropsy. 2. In the surgical group a close correlation was demonstrated between direct measurement of posterior wall thickness and the echocardiographic end-diastolic dimension (r = 0·76, P &lt; 0·001). 3. The necropsy measurement of posterior wall thickness correlated with the echocardiographic end-systolic dimension (r = 0·99, P &lt; 0·001). 4. These findings confirm that the echocardiographic measurement of posterior wall thickness accurately reflects the anatomical dimension.

Amyloid Cardiomyopathy

AbstractTransthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive, life-threatening disease characterized by deposition of insoluble amyloid fibrils in the myocardium, resulting in cardiac structural and functional abnormalities and ultimately heart failure. Disease frequency is reportedly lower in women than men, but sex-related differences have not been well established. We conducted a systematic literature review (SLR), based on PRISMA-P guidelines and registered with PROSPERO, to assess whether the epidemiology and clinical presentation of ATTR-CM differ between women and men. MEDLINE, Embase, and Cochrane databases and selected conference proceedings were searched (August 16, 2019) to identify observational and clinical studies reporting sex-specific data for patients with wild-type or hereditary ATTR-CM. Of 193 publications satisfying final eligibility criteria, 69 studies were included in our pooled analysis. Among the 4669 patients with ATTR-CM analyzed, 791 (17%) were women, including 174 (9%), 366 (29%), and 251 (18%) in studies of wild-type, hereditary, and undefined ATTR-CM, respectively. Data available on disease characteristics were limited and very heterogeneous, but trends suggested some cardiac structural/functional differences, i.e., lower interventricular septal and posterior wall thickness and left ventricular (LV) end diastolic diameter, and higher LV ejection fractions, in women versus men across ATTR-CM subtypes. Because LV wall thickness > 12 mm is generally the suggested threshold for ATTR-CM diagnosis in both sexes, smaller cardiac anatomy in women with the disease may lead to underdiagnosis. Additional research and studies are needed to elucidate potential disparities between sexes in ATTR-CM frequency, clinical characteristics, and underlying biological mechanisms. This study was registered within the International Prospective Register of Systematic Reviews (PROSPERO) database of the University of York (CRD42019146995).
