Abstract Objective: The aim of the study is to assess 24-hour blood pressure variability, circadian blood pressure profile and its relation to 24-hour blood pressure and cardiovascular risk factors in primary hypertension without any associated disease versus associated with a disease such as diabetes or chronic kidney disease. Methods: This observational study included 90 hypertensive patients, 49 with primary hypertension without associated disease and 41 patients with primary hypertension and diabetes or chronic kidney disease. Circadian blood pressure profile and 24-hour variability were assessed using ambulatory monitoring. Laboratory data regarding cardiovascular risk factors and demographic data were collected in a questionnaire. Results: The number of dipper patients was higher in the group without associated disease, but the difference was not statistically significant (p=0.27). In both groups a positive correlation was found between 24-hour systolic blood pressure variability and 24-hour systolic blood pressure (p=0.029) and was related to age (p=0.031). In the second group, systolic variability showed a positive correlation with serum triglycerides (p=0.006, r=0.416, CI: 0.1252 to 0.6422). Conclusion: Our findings suggest that systolic blood pressure variability is related to age, systolic blood pressure values and serum lipid levels. To prevent end organ damage in hypertension, the assessment of ambulatory monitoring derived 24-hour systolic blood pressure variability and its reduction may be at least as important as blood pressure lowering.

Long Term Effects

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.

Low Cardiovascular Risk

Introduction: Cardiovascular disease is the leading cause of mortality in old age, yet there is limited research on the patterns of cardiovascular risk factors that predict survival to 90 years. Hypothesis: The patterns of cardiovascular risk factors that portend longevity will differ from those that confer low cardiovascular risk. Methods: We examined repeated measures of blood pressure, LDL-cholesterol, and BMI from age 67 and survival to 90 years in the Cardiovascular Health Study (CHS). CHS is a prospective study of 5,888 black and white adults in two waves (1989-90 and 1992-93) from Medicare eligibility lists in four counties in the U.S. We restricted to participants aged 67 to 75 years at baseline to control for birth cohort effects and examined repeated measures of cardiovascular risk factors throughout the late-life course. We fit logistic regression models to predict survival to age 90 using generalized estimating equations, and modeled the risk factors as linear, a linear spline, and clinically relevant categories. Models were adjusted for demographics and medication use, and we also examined whether the association of each risk factor with longevity varied by the age of risk factor measurement. Best fit models are presented. Results: Among 3,645 participants in the birth cohort, 1,160 (31.8%) survived to 90 by June 16 th , 2015. Higher systolic blood pressure in early old age was associated with reduced odds for longevity, but there was an interaction with age such that the association crossed the null at 80 years. (Table) Among those with LDL-cholesterol <130 mg/dL, higher LDL-cholesterol was associated with greater longevity; at levels above 130 mg/dL there was no association between LDL-cholesterol and longevity. BMI had a u-shaped association with longevity. Conclusions: In summary, the patterns of risk factors that predict longevity differ from that considered to predict low cardiovascular risk. The risk of high systolic blood pressure appears to depend on the age of blood pressure measurement.

The Impact

Background: Antiphospholipid syndrome (APS) is characterised by increased thrombogenicity and/or pregnancy morbidity in the presence of raised levels of antiphospholipid antibodies (aPL). Increased oxidative properties of high density lipoprotein (HDL)(decreased activity of paraoxonase (PON)) is associated with increased risk for atherosclerosis and has been described in APS. The impact of PON on atherosclerotic disease progression in APS is unclear. We therefore examined the effect of PON on intima media thickness (IMT), and pulse wave velocity (PWV) in patients with positive aPL. Methods: We studied 77 women with positive aPL (aPL) aged 46.6±1.2 yrs (mean±SE) and a control group of 77 women aged 47.5±1.2 yrs matched for traditional cardiovascular risk factors. High resolution ultrasound was used to determine carotid IMT. Arterial stiffness was assessed non-invasively by carotid-radial PWV. PON activity was assessed by measuring p-nitrophenol formation and activity expressed as nmoles p-nitrophenol/ml serum/minute. Results: APL patients had significantly increased IMT and PWV compared to controls (0.75±0.02mm vs 0.65±0.01mm, p<0.001 and 9.14±0.18 m/s vs 8.56±0.21m/s, p<0.05 respectively). PON activity was significantly reduced in aPL compared to controls (91.5[64.3, 05.1]mmol/ml/min, median[IQR] vs 103.1[80.4, 111.5] mmol/ml/min, p<0.006). Although PON activity was not associated with vascular measures in controls, an inverse association was noted in aPL patients (r=−0.26 [cIMT] and r=−0.23 [PWV], both p<0.05). In multivariate analysis, accounting for cardiovascular risk factors, PON activity (β=−0.42, p<0.001), age (β=0.33, p<0.001) and systolic blood pressure (β=0.24, p<0.05) were independent determinants of cIMT while PON activity (β=−0.32, p<0.01) and systolic blood pressure (β=0.28, p<0.05) remained the only independent predictors of PWV in aPL positive patients. Conclusions: APS is associated with increased arterial stiffness and carotid intimal thickening. Paraoxonase activity is inversely associated with IMT and PWV in ApL positve patients. These findings indicate that oxidative stress may play an important role in the development of atherosclerosis in patients with primary antiphospholipid syndrome.

ObjectivesThe aim of this study was to use the parametric g-formula to estimate the 19-year risk of myocardial infarction (MI) under hypothetical interventions on six cardiovascular risk factors.Design and settingA populations-based cohort study with repeated measurements, the Tromsø Study.Primary outcome measureMyocardial infarction.ParticipantsWe estimated the relative and absolute risk reduction under feasible and intensive risk reduction strategies for smoking, physical activity, alcohol drinking, body mass index, total serum cholesterol and systolic blood pressure in 14 965 men and women with 19 years of follow-up (1994–2013).ResultsThe estimated 19-year risk of MI under no intervention was 7.5% in individuals with baseline mean age 49.3 years (range 25–69). This risk was reduced by 30% (95% CI 19% to 39%) under joint feasible interventions on all risk factors, and 70% (60%, 78%) under a set of more intensive interventions. The most effective interventions were lowering of total cholesterol to 5.18 mmol/L and lowering of systolic blood pressure to 120 mm Hg (33% and 37% lower MI risk, respectively). The absolute risk reductions were significantly larger in men, in older participants, in smokers and in those with low education.ConclusionModification of population levels of cardiovascular risk factors could have prevented close to one-third of the cases of MI in the municipality of Tromsø during 19 years of follow-up.
