Abstract Background Cardiovascular disease is one of the leading causes of death globally with hypertension being a primary cause of premature death from this disease process. Individuals with a family history of cardiovascular disease and hypertension are at a greater risk for developing the same sequela. Autonomic cardiac control is important in the level of cardiac function. One intervention that is effective in improving cardiovascular function is heart rate variability biofeedback training. The purpose of our study was to determine the effectiveness of heart rate biofeedback training on HRV and blood pressure in individuals with a family history of cardiovascular disease. Methods Thirty-four participants (76.5% female, 22.7 ± 4.3 years) completed a baseline assessment and training using an established short-term HRV protocol followed by two weeks of at-home paced breathing employing a smartphone application. The participants were then reassessed in a biofeedback clinic. Results The participants physiological measures showed a significant increase in means between pre and post intervention of SDNN (t (32) = 2.177, p =.037) and TP, (t (32) = 2.327 p = .026). Correlation noted a medium effect on diastolic blood pressure and high frequency heart rate variability, F, r = .41, n =33, p < .05. A multiple regression with all predictor variables in the model found no significance with diastolic and systolic blood pressure. Conclusions The findings from this pilot study demonstrated that a two-week paced breathing intervention may assist in reducing heart rate and diastolic blood pressure while improving heart rate variability.

Aims. Recent US guidelines advocate the introduction of lifetime or long-term absolute risk prediction for primary prevention of cardiovascular events, especially for young people and women. Therefore, long-term prediction models might be specially beneficial in population considered at low incidence. We aim to develop a 20-year absolute risk prediction equation in a Northern Italy population. Methods. Four independent population-based cohorts were enrolled between 1986 and 1994 from the Brianza population (Northern Italy), adopting standardized MONICA procedures. The study sample comprises n=2574 men and 2673 women, aged 35 to 69 years and free of CVD at baseline. Participants were followed-up for incidence of first coronary and ischemic stroke events (fatal and non-fatal; all MONICA validated) for a median time of 15 years (IQ range: 12-20) and up to the end of 2008. We compared several gender-specific Cox Proportional Hazards models: the basic one includes age, total cholesterol, HDL-cholesterol, systolic blood pressure, anti-hypertensive treatment, cigarette smoking and diabetes. Candidates to model addition were diastolic blood pressure, triglycerides, BMI, family history of CHD, and education. Model calibration was tested using the Grønnesby-Bogan goodness-of-fit statistic. The Area Under the ROC-Curve (AUC) was a measure of discrimination, corrected for over-optimism via bootstrapping. Changes in discrimination (Δ-AUC) and reclassification (Net Reclassification Improvement, NRI) defined the improvement from the basic model due to an additional risk factor. Intermediate risk was defined as 20-year risk between 10% and 40%. Results. We observed n=286 events in men (incidence rate 7.7 per 1000 person-years) and n=108 in women (2.6 per 1000 person-years). All risk factors included in the basic model were predictive of first cardiovascular event in both genders; discrimination was 0.725 and 0.802 in men and women, respectively. Average specificity in the top risk quintile (cut-off value: 23% in men and 8.5% in women) was similar in men and women (85% vs. 83%), while sensitivity was higher in women (63% vs. 46%). All the models were well-calibrated (p-values >0.05). The addition of a positive family history of CHD in men (Hazard Ratio: 1.6; 95%CI 1.2-2.1) and of diastolic blood pressure in women (HR: 1.4 for 11 mmHg increase; 1.1-1.8) significantly improved discrimination (Δ-AUC=0.01; 95%CI 0.002-0.02 [men] and Δ-AUC=0.005; 95%CI 0.0001-0.01 [women]) and reclassification of subjects at intermediate risk (NRI=8.4%;1.7%-19.1% [men]; and NRI=11.7%; -3.2%-33.5% [women]). Conclusions. Traditional risk factors are predictive of cardiovascular events after 20 years, with good discrimination. The addition of family history of CHD may contribute to model improvement, at least among men; the role of diastolic blood pressure in women should be carefully evaluated.

Importance: Individuals with schizophrenia have a reduced life-expectancy compared to the general population, largely due to an increased risk of cardiovascular disease (CVD). Clinical and epidemiological studies have been unable to fully unravel the nature of this relationship. Objective: Investigate genetic correlations and potential bi-directional effects between liability to schizophrenia and CVD. Design, setting, and participants: We obtained summary-data of genome-wide-association studies of schizophrenia (N=130,644), heart failure (N=977,323), coronary artery disease (N=332,477), systolic and diastolic blood pressure (N=757,601), heart rate variability (N=46,952), QT interval (N=103,331), early repolarization and dilated cardiomyopathy ECG patterns (N=63,700). We computed genetic correlations with linkage disequilibrium score regression and conducted bi-directional Mendelian randomization (MR). With multivariable MR, we investigated whether associations were mediated by smoking, body mass index, physical activity, lipid levels, or type 2 diabetes. To ensure robustness, we applied a range of sensitivity methods. Main outcomes and measures: Schizophrenia, heart failure, coronary artery disease, systolic blood pressure, diastolic blood pressure, heart rate variability, QT interval, early repolarization, dilated cardiomyopathy. Results: Genetic correlations between liability to schizophrenia and CVD were close to zero (-0.02 to 0.04). With MR, we found robust evidence that liability to schizophrenia increases heart failure risk. This effect remained consistent with multivariable MR. There was also evidence that liability to schizophrenia increases early repolarization risk, largely mediated by BMI and lipid levels. Finally, there was evidence that liability to schizophrenia increases heart rate variability, a direction of effect contrasting previous studies. In the other direction, there was weak evidence that higher systolic, but not diastolic, blood pressure increases schizophrenia risk. Conclusions and relevance: Our findings indicate that liability to schizophrenia increases the risk of heart failure, and that this is not mediated by key health behaviours. This is consistent with the notion that schizophrenia is characterised by a systemic dysregulation of the body (including inflammation and oxidative stress) with detrimental effects on the heart. To decrease cardiovascular mortality among schizophrenia patients, priority should lie with optimal treatment and interventions in early stages of psychoses. We also identified early repolarization, currently understudied, as a potential CVD marker among patients with schizophrenia.

Background: Hypertension is considered as a major health issue in developed as well as developing countries and its possible origin during childhood prompts pediatricians to routinely include measurement of blood pressure (BP) as an integral part of pediatric physical examination. The objectives of the study were to evaluate the normal range of blood pressure in adolescent school going students of 12-16 years, prevalence of hypertension and relationship of BP with variables like age, body mass index (BMI), socioeconomic status and family history of hypertension.Methods: A cross sectional study was undertaken for a period of one year in adolescent school children in age groups between 12-16 years. Detailed clinical examination was done in 1060 adolescent school children and BP was recorded in right upper limb and correlation of BP with BMI, family history of hypertension and diabetes were studied.Results: Mean systolic and diastolic pressure showed linear relationship with age. There was a highly statistically significant difference between mean systolic and diastolic blood pressure between lower and middle socio-economic class. Prevalence of obesity in our study was 1.13%, overweight was 7.83%. Prevalence of hypertension in obese children was 33.33% and in overweight children 18.07%. Family history of hypertension and diabetes carry a significant correlation with elevated systolic and diastolic blood pressure in adolescents.Conclusions: This study revealed that socio economic factors play a significant role in determining the blood pressure of the individual. Children of middle class have significantly elevated mean systolic pressure and mean diastolic pressure than low socio-economic groups.

Hypertension is one of the major risk factors associated with cardiovascular diseases. In this study, we will assess the frequency of hypertension among healthy university students and its association with gender, body mass index, smoking, and family history of both hypertension and cardiovascular diseases. We screened healthy university students ranging from 18 to 26 years of age. For each participant, we performed blood pressure measurements using a previously validated device and obtained demographic data, body mass index (BMI), smoking status, and family history of both hypertension and cardiovascular diseases. Out of the total number of 505 participants included in this study, 35.2% have blood pressure between 130/80 and 139/89, and 13.5% have blood pressure of more than 140/90. We found significant gender differences in both systolic pressure (p = 0.003) with mean difference = 18.08 mmHg (CI: 16.13 to 19.9) and diastolic pressure (p = 0.011) with mean difference = 3.6 mmHg (CI: 2.06 to 5.14), higher in males than in females. Upon comparing the mean difference in both systolic and diastolic blood pressure with BMI, we found significant differences in both systolic (p < 0.001) and diastolic (p = 0.002) blood pressure. We also found that smokers have significantly (p = 0.025) higher systolic blood pressure (mean difference = 4.2 mmHg, CI: 3.2 mmHg to 8.8 mmHg), but no significant difference for diastolic blood pressure (p = 0.386), compared to nonsmokers. First-degree family history of both hypertension and cardiovascular diseases affected systolic but not diastolic blood pressure. Taking into account the adverse short- and long-term effect of hypertension, we recommend adopting an awareness program highlighting the importance of screening blood pressure in young adolescent populations, keeping in mind that both high BMI and smoking are important modifiable factors.

The frequency of administration of combinations of antihypertensive drugs and its changes at different stages of observation was studied in 60 patients with difficult-to-control arterial hypertension (DTCAH) (32 men and 28 women) aged 59.0 ± 9.4. All patients were randomly divided into two subgroups: biofeedback (BFB) in the loop of paced breathing (PB) and heart rate variability (HRV) (33 patients) – basic subgroup, subgroup of comparisons (27 patients). Determined that patients with DTCAH in the subgroup of patients with the BFB in the loop of PB there has been a reduction of four-component antihypertensive therapy to three-component and in the subgroup of comparisons the frequency of the appointment of a four-component therapy was increased. At the same time, it was found that the addition of drug therapy with regular BFB sessions in the loop of PB contributed to the potentiation of the antihypertensive effect in patients with DTCAH. It is concluded that the BFB in the loop of PB and HRV can be used as a technology to improve the efficiency of control of blood pressure in patients with DTCAH.

Summary Objective: To describe the values of non-HDL cholesterol (NHDL-c) and the frequency of a family history of early cardiovascular disease (family HCVD) in healthy prepubescent children. Analyze the association between NHDL-c and family HCVD, and possible associations with other risk factors for cardiovascular disease (CVD). Method: Cross-sectional study including 269 prepubescent (aged 6-10 years) schoolchildren with a normal body mass index (+1SD<BMI>-2SD). Data collected: Family HCVD; weight and height, waist circumference and systemic blood pressure; lipid profile (total cholesterol TC, HDL-c, triglycerides and LDL-c), NHDL-c calculation (CT-HDL-c, cut-off = 145 mg/dL) and insulin resistance (HOMA-IR). Results: High levels were found for NHDL-c in 10 (3.7%) of these schoolchildren, and family early HCVD was found in 46 (17.1%) of them. There was a weak association between family HCVD and NHDL-c (Cramer’s-V-test = 0.120; p=0.050). Among the children with NHDL-c≥145 mg/dL, 4 (40%) have family HCVD. The presence of family HCVD was not associated with the variables being studied. The variables independently associated with NHDL-c ≥ 145 mg/dL were: HOMA-IR (OR=1.7; 95CI 1.1-2.6) and diastolic blood pressure (OR=1.1; 95CI 1.02-1.2). Conclusion: NHDL-c values were associated with blood pressure and insulin resistance. Family HCVD was not associated with other classic risk factors for CVD, even though the frequency found was five times higher than that of high NHDL-c.
