Background/Aims. Overt hypothyroidism is disease associated with accelerated arteriosclerosis and coronary heart disease. Whether subclinical hypothyroidism (SH) is associated with increased cardiovascular risk is contraversial. As SH is a high prevalence thyroid dysfunction, specially in older women, it is important to evaluate cardiovascular risk factors in these patients and that was the aim of this study. Methods. We examined 30 patients with SH and 20 healthy controls. Subclinical hypothireoidism was defined as an elevated thyrotropin (TSH) (> 4.5 mU/L) and normal free thyroxine (FT4) level. In all the participants we determined body mass index (BMI), blood pressure, TSH, FT4, antibodies to thyroid peroxidase, antibodies to thyroglobulin, total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein (LDL) cholesterol, triglicerides, total cholesterol/HDL cholesterol ratio and LDL/HDL cholesterol ratio. Results. Mean BMI in patients with SH was significantly higher (p < 0.05), as well as diastolic blood pressure (p < 0.01) compared with the controls. Average levels of total cholesterol (5.40?0.62 vs 5.06?0.19 mmol/l, p < 0.01) and triglycerides (2.16?0.56 vs 1.89?0.24 mmol/l, p < 0.05) were also significantly higher in the group with SH. Individual analysis revealed that the percentage of patients with SH having borderline elevated total cholesterol (63.33%), hypertrigliceridemia (43.33%) and elevated total cholesterol/HDL cholesterol ratio (26.67%) were significantly higher than the percentage in the controls. No significant correlation between TSH and lipid parameters was detected. Conclusion. Subclinical hypothyroidism was associated with higher BMI, diastolic hypertension, higher total cholesterol and triglicerides levels and higher total cholesterol/HDL cholesterols ratio. This might increase the risk of accelerated arteriosclerosis in patients with SH.

Abstract Background The population age 90 years and older is the fastest growing segment of the U.S. population. Only recently is it possible to study the factors that portend survival to this age. Methods Among participants of the Cardiovascular Health Study, we studied the association of repeated measures of cardiovascular risk factors measured over 15–23 years of follow-up and not only survival to 90 years of age, but also healthy aging outcomes among the population who reached age 90. We included participants aged 67–75 years at baseline (n = 3,613/5,888) to control for birth cohort effects, and followed participants until death or age 90 (median follow-up = 14.7 years). Results Higher systolic blood pressure was associated with a lower likelihood of survival to age 90, although this association was attenuated at older ages (p-value for interaction &lt;.001) and crossed the null for measurements taken in participants’ 80’s. Higher levels of high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and body mass index (BMI) were associated with greater longevity. Among the survivors to age 90, those with worse cardiovascular profile (high blood pressure, LDL cholesterol, glucose, and BMI; low HDL cholesterol) had lower likelihood of remaining free of cardiovascular disease, cognitive impairment, and disability. Conclusion In summary, we observed paradoxical associations between some cardiovascular risk factors and survival to old age; whereas, among those who survive to very old age, these risk factors were associated with higher risk of adverse health outcomes.

Background: High-density lipoprotein cholesterol (HDL-C) as an invaluable predictor is used to determine the risk of heart diseases and evaluate the effectiveness of lipid-lowering therapies. Objectives: In this study, we aimed to investigate the association between HDL cholesterol level and some cardiovascular risk factors in the patients referring to the Heart Clinic of Birjand, Iran, during 2016 - 2017. Methods: In this cross-sectional study, 410 patients referring to the Heart Clinic of Birjand, Iran, during 2016 - 2017 were selected. Then using a questionnaire, complete demographic and biochemical data were collected and statistically analyzed for assessing the effects of some lifestyle factors such as the diet and physical activity on the serum level of HDL. Finally, all the results were analyzed by SPSS software (version 15). Results: In our study, the majority of dyslipidemic people had low levels of HDL (58.8%). Most of the participants were in a poor health condition according to BMI and physical activity, in a moderate health status in terms of smoking and cholesterol and fasting blood glucose (FBS) levels, and finally in the ideal health group in terms of the diet and blood pressure. The HDL level was significantly associated with physical activity, FBS, BMI, and blood pressure (P < 0.05). Conclusions: Considering the association between persistent cardiovascular risk factors and HDL cholesterol level, encouraging people to adopt a healthy lifestyle can help prevent cardiac diseases.

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): The Norwegian health department Background The evidence of the long-term effects of multiple lifestyle intervention on cardiovascular risk is uncertain. We aimed to summarize the evidence from randomized clinical trials examining the efficacy of lifestyle intervention on major cardiovascular risk factors in subjects at high cardiovascular risk. Methods  Eligible trials investigated the impact of lifestyle intervention versus usual care with minimum 24 months follow-up, reporting more than one major cardiovascular risk factor. A literature search updated April 15, 2020 identified 12 eligible studies. The results from individual trials were combined using fixed and random effect models, using the standardized mean difference (SMD) to estimate effect sizes. Small-study effect was evaluated, and heterogeneity between studies examined by subgroup and meta-regression analyses considering patient- and study-level variables. Results  Small-study effect was not identified. Lifestyle intervention reduced systolic blood pressure modestly with an estimated SMD of -0.13, 95% confidence interval (CI): -0.21 to -0.04, with moderate heterogeneity (I² = 59%), corresponding to a mean difference of approximately 2 mmHg (MD = -1.86, 95% CI: -3.14 to -0.57, p = 0.0046). This effect disappeared in the subgroup of trials judged at low risk of bias (SMD = 0.02, 95% CI: -0.08 to 0.11). For the outcome total cholesterol SMD was -0.06, 95% CI: -0.13 to 0.00, with no heterogeneity (I² = 0%), indicating no effect of the intervention. Conclusion  Lifestyle intervention resulted in only a modest effect on systolic blood pressure and no effect on total cholesterol after 24 months. Further lifestyle trials should consider the challenge of maintaining larger long-term benefits to ensure impact on cardiovascular outcomes.

AbstractThe association between dietary patterns and metabolic cardiovascular risk factors has long been addressed but there is a lack of evidence towards the effects of the overall diet on the complex net of biological inter-relationships between risk factors. This study aimed to derive dietary patterns and examine their associations with metabolic cardiovascular risk factors following a theoretic model for the relationship between them. Participants included 417 adults of both sexes, enrolled to the cross-sectional population-based study performed in Brazil. Body weight, waist circumference, high-sensitivity C-reactive protein, blood pressure, total cholesterol:HDL-cholesterol ratio, TAG:HDL-cholesterol ratio, fasting plasma glucose and serum leptin were evaluated. Food consumption was assessed by two non-consecutive 24-h dietary recalls adjusted for the within-person variation of intake. A total of three dietary patterns were derived by exploratory structural equation modelling: ‘Traditional’, ‘Prudent’ and ‘Modern’. The ‘Traditional’ pattern had a negative and direct effect on obesity indicators (serum LEP, body weight and waist circumference) and negative indirect effects on total cholesterol:HDL-cholesterol ratio, TAG:HDL-cholesterol ratio and fasting plasma glucose. The ‘Prudent’ pattern had a negative and direct effect on systolic blood pressure. No association was observed for the ‘Modern’ pattern and metabolic risk factors. In conclusion, the ‘Traditional’ and ‘Prudent’ dietary patterns were negatively associated with metabolic cardiovascular risk factors among Brazilian adults. Their apparent protective effects against obesity and high blood pressure may be important non-pharmacological strategies for the prevention and control of obesity-related metabolic disorders and CVD.

Objective: Our study was designed to compare the gender difference in Blood Pressure Control and Cardiovascular Risk Factors in patients of Liaquat University of Medical and Health Sciences Jamshoro Pakistan. Methodology: This cross-sectional study was conducted in  Liaquat University of Medical and Health Sciences Jamshoro Pakistan from December 2019 to December 2020. Blood pressure was measured twice by trained physicians using aneroid sphygmomanometers after a standardized protocol. Patients were asked to sit with both feet on the floor for ≥5 minutes before the first BP measurement. Both the two BP measurements were taken 60 seconds apart.  For this research we defined hypertension as systolic BP ≥140 mm Hg, diastolic BP ≥90 mm Hg. Results:  We conducted a comparison between Hypertensive and nonhypertensive participants of the male and female groups. High blood pressure increased the level of uric acid in both male and female groups (351 ± 92 vs 303 ± 75). We observed that the hypertensive male population reported a high prevalence of cardiovascular risk factors due to  increase amount of total cholesterol level, triglyceride and low-density lipoprotein cholesterol (5.45 ± 1.01, 1.42 ±  0.85,  2.56 ± 0.70) than females (5.15 ± 0.91, 1.29 ± 0.87, 2.30 ± 0.63). Conclusion: Our results concluded that the male hypertensive population is more prone to future cardiovascular risk due to increased amount of total cholesterol levels, triglycerides, and low-density lipoprotein cholesterol, and sex hormones (androgens).

ObjectiveTo examine the association between age at period cessation and trajectories of anthropometry, blood pressure, lipids and glycated haemoglobin (HbA1c) from midlife to age 69 years.MethodsWe used data from the UK Medical Research Council National Survey of Health and Development to examine the association between age at period cessation and trajectories of systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI) and waist circumference (WC) from 36 to 69 years and trajectories of triglyceride, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and HbA1c from 53 to 69 years.ResultsWe found no evidence that age at period cessation was associated with trajectories of log triglyceride, LDL-C and HDL-C from 53 to 69 years and trajectories of SBP or DBP from 36 to 69 years, regardless of whether period cessation occurred naturally or due to hysterectomy. While we found some evidence of associations of age at period cessation with log BMI, log WC and log HbA1c, patterns were not consistent and differences were small at age 69 years, with confidence intervals that spanned the null value.ConclusionHow and when women experience period cessation is unlikely to adversely affect conventional cardiovascular risk factors across mid and later life. Women and clinicians concerned about the impact of type and timing of period cessation on conventional cardiovascular intermediates from midlife should be reassured that the impact over the long term is small.

As part of the Dutch Nutrition Surveillance System, cardiovascular risk factors and food consumption (24 h recall) as well as haematological, Fe and vitamin status (A, B6, C) were assessed in 126 Dutch boys aged 10–11 years (response 71 %). Body mass index (BMI) and the sum of four skinfolds were strongly associated (r0.85,P< 0.01) and 8% of the boys were overweight (BMI > 20.1 kg/m2). Elevated serum total cholesterol levels (> 4.4 mmol/l) were observed in 38 %; total cholesterol and low-density-lipoprotein-cholesterol levels were strongly associated (r0.88,P< 0.001). Intake of fat was high (38 % of energy) and too much fat was saturated (polyunsaturated: saturated 0.44, guideline: 0.5–1.0), whereas intake of carbohydrate (49% of energy) and dietary fibre was low. About 12% of the boys had insufficient Fe stores (plasma ferritin < 12.0 μg/l) and the mean Fe intake (9.0 mg/d) was below recommended daily allowance (10.0 mg/d). Plasma ferritin was, however, not associated with haematological indices and no frank anaemias were observed. No marginal values were observed for vitamins A, B6and C status. In conclusion, the main nutritional risks in boys aged 10–11 years are cardiovascular risk factors and Fe nutrition.

A large multicentre study involving 6003 [3044 males, 2959 females; mean (± SD) age 59 ± 11 years] mild-to-severe hypertensive patients was carried out to evaluate the effects of the angiotension converting enzyme inhibitor quinapril on blood pressure and on metabolic cardiovascular risk factors during 3 − 6 months' treatment (mean follow-up 90.4 days). The study population included 551 elderly [mean (± SD) age 71.9 ± 9.3 years] patients, 1314 subjects with diabetes mellitus and 154 non-diabetic patients with hyperlipaemia; 4% of patients were lost to follow-up. Diastolic blood pressure decreased from 102 to 87 mmHg (intent-to-treat analysis) and 62% of patients were normalized (diastolic blood pressure below 90 mmHg) at the last evaluable visit. Overall, serum lipids were favourably affected during quinapril treatment; when corrected for changes in body weight, a significant improvement in total, low- and high-density lipoprotein cholesterol, and triglycerides was detected. Quinapril treatment in elderly patients was efficacious and well tolerated, and quinapril appears to be an effective antihypertensive drug devoid of untoward effects on metabolic risk factors for cardiovascular disease.
