Abstract Context: Increasing evidence suggests that adverse conditions during early prenatal life are associated with cardiometabolic dysfunction in postnatal life. In vitro fertilization (IVF) conception may be an early prenatal life event with long-term health consequences. Objective: Our objective was to investigate several cardiometabolic measures in 8- to 18-yr-old IVF singletons and spontaneously conceived controls born from subfertile parents. Design and Setting: This follow-up study was conducted at the VU University medical center, Amsterdam, The Netherlands. Participants: Blood pressure was examined in 225 IVF-conceived children and 225 age- and gender-matched spontaneously conceived control children. Several indicators of insulin resistance were studied in a pubertal subpopulation (131 IVF children and 131 controls). Main Outcome Measures: Blood pressure, fasting glucose, and fasting insulin were determined. Results: Systolic and diastolic blood pressure levels were higher in IVF children than controls (109 ± 11 vs. 105 ± 10 mm Hg, P < 0.001; and 61 ± 7 vs. 59 ± 7 mm Hg, P < 0.001, respectively). Children born after IVF were also more likely to be in the highest systolic and diastolic blood pressure quartiles (odds ratio = 2.1, 95% confidence interval 1.4, 3.3; odds ratio = 1.9, 95% confidence interval 1.2, 3.0, respectively). Furthermore, higher fasting glucose levels were observed in pubertal IVF children (5.0 ± 0.4 vs. 4.8 ± 0.4 mmol/liter in controls; P = 0.005). Blood pressure and fasting glucose differences could not be explained by current body size, birth weight, and other early life factors or by parental characteristics, including subfertility cause. Conclusions: These findings highlight the importance of continued cardiometabolic monitoring of IVF-conceived children and might contribute to current knowledge about periconceptional influences and their consequences in later life.

Abstract Background Hypertension is one of the major risk factors of cardiovascular events in patients with atrial fibrillation (AF). However, relationship between diastolic blood pressure (DBP) and cardiovascular events in AF patients remains unclear. Methods The Fushimi AF Registry is a community-based prospective survey of AF patients in Japan. Follow-up data were available in 4,466 patients, and 4,429 patients with available data of DBP were examined. We divided the patients into three groups; G1 (DBP<70 mmHg, n=1,946), G2 (70≤DBP<80, n=1,321) and G3 (80≤DBP, n=1,162), and compared the clinical background and outcomes between groups. Results The proportion of female was grater in G1 group, and the patients in G1 group were older and had higher prevalence of heart failure (HF), diabetes mellitus (DM), chronic kidney disease (CKD). Prescription of beta blockers was higher in G1 group, but that of renin-angiotensin system-inhibitors and calcium channel blocker was comparable. During the median follow-up of 1,589 days, in Kaplan-Meier analysis, the incidence rates of cardiovascular events (composite of cardiac death, ischemic stroke and systemic embolism, major bleeding and HF hospitalization during follow up) were higher in G1 group and G3 group than G2 group (Figure 1). When we divided the patients based on the systolic blood pressure (SBP) at baseline (≥130 mmHg or <130 mmHg), the incidence of rates of cardiovascular events were comparable among groups. Multivariate Cox proportional hazards regression analysis including female gender, age (≥75 years), higher SBP (≥130 mmHg), DM, pre-existing HF, CKD, low left ventricular ejection fraction (<40%) and DBP (G1, G2, G3) revealed that DBP was an independent determinant of cardiovascular events (G1 group vs. G2 group; hazard ratio (HR): 1.40, 95% confidence intervals (CI): 1.19–1.64, G3 group vs. G2 group; HR: 1.23, 95% CI: 1.01–1.49). When we examined the impact of DBP according to 10 mmHg increment, patients with very low DBP (<60 mmHg) (HR: 1.50,95% CI:1.24–1.80) and very high DBP (≥90 mmHg) (HR: 1.51,95% CI:1.15–1.98) had higher incidence of cardiovascular events than patients with DBP of 70–79 mmHg (Figure 2). However, when we examined the impact of SBP according to 20 mmHg increment, SBP at baseline was not associated with the incidence of cardiovascular events (Figure 3). Conclusion In Japanese patients with AF, DBP exhibited J curve association with higher incidence of cardiovascular events. Funding Acknowledgement Type of funding source: None

Multiple Visit

Previous studies of childhood blood pressure have shown tracking correlations, which estimate the magnitude of association between initial and subsequent measurements, to be lower than corresponding adult values. Inasmuch as this disparity could arise from failing to account for a larger week-to-week variability in children, blood pressure was measured for 4 successive years, on four weekly visits in each year, and with three measurements at each visit, using a random-zero sphygmomanometer, in a cohort of 333 schoolchildren aged 8 through 15 at entry. Ninety percent of subjects had measurements in 1 or more years of follow-up. For all follow-up periods (1, 2, and 3 years from baseline), the Pearson correlation coefficient (r) for both systolic and diastolic blood pressure rose substantially with the number of weekly visits used to calculate each subject's yearly blood pressure (P < .0001). For systolic pressure, the 3-year r values for 1, 2, 3, and 4 visits were .45, .55, .64, and .69, respectively. For diastolic pressure (Korotkoff phase 4), the corresponding values were .28, .41, .47, and .54. These higher multiple-visit estimates of tracking approximate published adult values and raise the possibility that prediction of adult blood pressure from childhood measurements may be improved by averaging readings from multiple weekly visits.

Spot Urine

Excessive salt intake is a risk factor for hypertension. The most reliable method for estimating daily salt intake is measurement of 24-h urinary sodium excretion, while it is inconvenient. Sodium-to-potassium ratio (Na/K) of a urine sample is another index of salt loading. We previously reported that a simple measure of spot urine Na/K might be a representative of salt loading in a cross-sectional setting. Here, we conducted a longitudinal study aiming to clarify a prognostic significance of spot urine Na/K for increasing blood pressure (BP) levels. Study subjects consists of 9,769 general individuals. Among them, individuals whose baseline Na/K was available (n=9,328), who were normotensive at baseline (n=6,392), and who participated in the follow-up measurement (n=5,209) were included in this analysis (51.8±12.9 years old, male: 29.2%). Mean follow-up duration was 5.0±0.5 years. Mean Na/K at baseline was 3.1±1.7, and showed step-wise increase with BP levels (optimal: 3.0±1.6, normal: 3.3±1.8, high normal: 3.4±1.8, P<0.001). Other major factors that were significantly associated with Na/K was fasting time (r=-0.220, P<0.001), and CKD (CKD (n=694): 2.7±1.6, control: 3.2±1.7, P<0.001). Mean SBP was significantly increased during follow-up period (baseline: 116±12, follow-up: 119±15 mmHg), and 805 individuals (15.5%) were newly diagnosed as hypertension (HT). These individuals were significantly older (HT: 60.3±9.9, NT: 50.3±12.8 years), were frequently male (36.4%, 27.9%), and had higher SBP (127±9, 115±11 mmHg) at baseline (P<0.001). In contrast, baseline spot urine Na/K was slightly lower in individuals who developed HT (3.0±1.6, 3.1±1.8, P=0.013), while that measured at follow-up investigation was oppositely higher in hypertensives (3.1±1.8, 2.8±1.5, P<0.001). Multiple linear regression analysis adjusted for the covariates identified baseline Na/K (β=0.108, P<0.001) and changes in Na/K during follow-up period (β=0.222, P<0.001) as independent determinants for future SBP levels. Higher spot urine Na/K, as well as increases in the Na/K levels, was significant determinant for future BP levels. The apparently lower baseline Na/K levels in individuals who developed HT might be due to reverse causality.

The efficacy and safety of sustained-release diltiazem, 200 – 300 mg once daily was compared with that of captopril, 12.5 – 25 mg twice-daily, in 100 elderly patients (65 – 85 years old) with mild to moderate essential hypertension (supine diastolic blood pressure 95 – 115 mmHg). All patients received placebo for 2 weeks, followed by an 8-week double-blind period, and were randomized to either diltiazem ( n = 50) or captopril ( n = 50). Their blood pressure was measured at trough level at week 4 immediately before dosing, i.e. 24 h post diltiazem dose or 12 h post captopril dose. Also at week 4, in non-responders, diltiazem was increased from 200 to 300 mg once daily and captopril from 12.5 to 25 mg twice daily to achieve a target supine diastolic blood pressure reduction of at least 10 mmHg or a diastolic blood pressure below 90 mmHg. Supine diastolic blood pressure, at week 8, was significantly ( P < 0.001) reduced from 102 ± 1 to 90 ± 1 mmHg with diltiazem and from 103 ± 1 to 89 ± 1 mmHg with captopril, bringing this parameter within normal limits for both groups. Supine systolic blood pressure was also significantly ( P < 0.001) reduced. Target blood pressure was achieved in 68% of patients taking diltiazem and in 70% taking captopril. Distribution of adverse events was comparable in both groups; no significant changes in laboratory or electrocardiographic parameters occurred. Two serious events were reported with captopril: one sudden death and one cerebrovascular stroke. Sustained-release diltiazem once a day is a convenient, well tolerated, first line treatment for hypertension in the elderly, for whom the possibility of using two dose levels allows a close regimen adjustment, 200 mg being recommended as a starting dose.

The Relationship

Background: Many genes and environmental factors linked to Alzheimer’s disease (AD) risk affect lipid metabolism or the cardiovascular system, strongly implicating cerebrovascular and metabolic dysfunction in AD pathogenesis. Although some PUFAs may improve cognitive function in aging individuals, it is still unclear how different PUFAs influence AD neuropathology and cognitive function. Objective: To examine the influence of polyunsaturated fatty acid (PUFA) metabolism on AD-associated cognitive decline, we investigated the relationship between serum PUFA profile and neuropsychological test performance. Methods: Cognitive functioning in patients with probable AD (n = 174, mean age 77.6 years) was examined using the Mini-Mental State Exam (MMSE) and clock drawing test (CDT). Serum samples were obtained for PUFA profile, including the eicosapentaenoic acid/arachidonic acid (EPA/AA) ratio, and measurement of brain natriuretic peptide (BNP) concentration. In the follow-up study, 47 subjects repeated MMSE and CDT after 1 year, According to the second MMSE score, the subjects were divided into the following 2 groups: those with unchanged or improved MMSE score and those with lower MMSE score. A receiver operating characteristic curve was used to evaluate the relationship between the EPA/AA ratio and 1-year cognitive stability. Results: In the cross-sectional study, total MMSE score correlated positively with the EPA/AA ratio and systolic blood pressure (SBP), and negatively with age and diastolic blood pressure (DBP) (p < 0.05). In the follow-up study, the MMSE score was lower than baseline in 20 subjects, whereas it was improved or unchanged in 29 patients. The EPA/AA ratio in the stable group was significantly greater than that in the deteriorating group, suggesting an association between higher EPA/AA ratio and cognitive stability over 1 year. The EPA/AA ratio predicted stability of cognitive performance with a sensitivity of 66% and specificity of 70% (odds ratio = 4.43) when the cut-off was 0.67. Conclusion: Our results suggest that serum EPA concentration strongly influences cognitive performances in AD patients. The EPA/AA ratio was a sensitive indicator of cognitive stability in this patient group.
