Recurrent Event

ObjectiveThe aim of the current study was to assess the relationship between classic cardiovascular risk factors and risk of not only the first recurrent atherosclerotic cardiovascular event, but also the total number of non-fatal and fatal cardiovascular events in patients with recently clinically manifest cardiovascular disease (CVD).DesignProspective cohort study.SettingTertiary care centre.Participants7239 patients with a recent first manifestation of CVD from the prospective UCC-SMART (Utrecht Cardiovascular Cohort - Second Manifestations of ARTerial disease) cohort study.Outcome measuresTotal cardiovascular events, including myocardial infarction, stroke, vascular interventions, major limb events and cardiovascular mortality.ResultsDuring a median follow-up of 8.9 years, 1412 patients had one recurrent cardiovascular event, while 1290 patients had two or more recurrent events, with a total of 5457 cardiovascular events during follow-up. The HRs for the first recurrent event and cumulative event burden using Prentice-Williams-Peterson models, respectively, were 1.36 (95% CI 1.25 to 1.48) and 1.26 (95% CI 1.17 to 1.35) for smoking, 1.14 (95% CI 1.11 to 1.18) and 1.09 (95% CI 1.06 to 1.12) for non-high-density lipoprotein (HDL) cholesterol, and 1.05 (95% CI 1.03 to 1.07) and 1.04 (95% CI 1.03 to 1.06) for systolic blood pressure per 10 mm Hg.ConclusionsIn a cohort of patients with established CVD, systolic blood pressure, non-HDL cholesterol and current smoking are important risk factors for not only the first, but also subsequent recurrent events during follow-up. Recurrent event analysis captures the full cumulative burden of CVD in patients.

Endothelin 1

Introduction Diabetic peripheral neuropathy (DPN) is a common microvascular complication in patients with type 2 diabetes (T2D). Apart from hyperglycemia, few modifiable risk factors have been identified. Endothelin-1 is a potent vasoconstrictor peptide, implicated in the causal pathway of microangiopathy. We investigated whether baseline plasma endothelin-1 and other metabolic and vascular risk factors predicted the incidence of DPN. Design This is a 3-year observational, cohort study. Methods In patients with T2D (n = 2057), anthropometric data, fasting blood, and urine were collected for biochemistry and urine albumin/creatinine measurements. Forearm cutaneous endothelial reactivity was assessed by iontophoresis and laser Doppler flowmetry/imaging. Measurements were repeated on follow-up. Incident DPN was considered present if an abnormal finding in monofilament (<8 of 10 points) or neurothesiometer testing was ≥25 volts on either foot at 3-year follow-up, but normal at baseline. Plasma endothelin-1 was assessed by ELISA. Results At baseline, mean age of patients was 57.4 ± 10.8 years old and prevalence of DPN was 10.8%. Of the 1767 patients without DPN, 1250 patients returned for follow-up assessment ((2.9 ± 0.7) years), with a 10.7% incidence of DPN. Patients with incident DPN had significantly higher baseline endothelin-1 (1.43 (1.19–1.73) vs 1.30 (1.06–1.63)) pg/mL, P < 0.0001. Multivariable Cox proportional hazards ratio showed a 1-s.d. increase in log endothelin-1 (adjusted HR: 4.345 (1.451–13.009), P = 0.009), systolic blood pressure (per 10-unit) (adjusted HR: 1.107 (1.001–1.223), P = 0.047) and diabetes duration (adjusted HR: 1.025 (1.004–1.047), P = 0.017) predicted incident DPN, after adjustment for glycemic control, eGFR, albuminuria, peripheral arterial disease and retinopathy status. Conclusion Higher baseline endothelin-1, blood pressure and diabetes duration were significant and independent predictors for incident DPN. Validation of our findings in independent cohorts and molecular mechanistic studies will help better our understanding on the role of endothelin-1 in DPN.

Abstract Aims To evaluate the bidirectional relationship between blood pressure (BP) and depressive symptoms using a large prospective cohort study. Methods Prospective cohort study was performed in 276 244 adults who participated in a regular health check-up and were followed annually or biennially for up to 5.9 years. BP levels were categorised according to the 2017 American College of Cardiology and American Heart Association hypertension guidelines. Depressive symptoms were assessed using Centre for Epidemiologic Studies-Depression (CESD) questionnaire and a cut-off score of ≥25 was regarded as case-level depressive symptoms. Results During 672 603.3 person-years of follow-up, 5222 participants developed case-level depressive symptoms. The multivariable-adjusted hazard ratios (HRs) [95% confidence interval (CI)] for incident case-level depressive symptoms comparing hypotension, elevated BP, hypertension stage 1 and hypertension stage 2 to normal BP were 1.07 (0.99–1.16), 0.93 (0.82–1.05), 0.89 (0.81–0.97) and 0.81 (0.62–1.06), respectively (p for trend <0.001). During 583 615.3 person-years of follow-up, 27 787 participants developed hypertension. The multivariable-adjusted HRs (95% CI) for incident hypertension comparing CESD 16–24 and ⩾25 to CESD < 16 were 1.05 (1.01–1.11) and 1.12 (1.03–1.20), respectively (p for trend <0.001) and in the time-dependent models, corresponding HRs (95% CI) were 1.12 (1.02–1.24) and 1.29 (1.10–1.50), respectively (p for trend <0.001). Conclusions In this large cohort study of young and middle-aged individuals, higher BP levels were independently associated with a decreased risk for developing case-level depressive symptoms and depressive symptoms were also associated with incident hypertension. Further studies are required to elucidate the mechanisms underlying the bidirectional association between BP levels and incident depression.

Cvd Mortality

Abstract Background Cardiovascular disease (CVD) is a leading cause of premature death in Cuba, accounting for about one third of all deaths under age 70 years. Substantial uncertainty remains, however, about the relevance of major metabolic risk factors to CVD mortality in this population. Purpose To relate body-mass index (BMI), systolic blood pressure (SBP), and diabetes to risk of CVD death in Cuba. Methods In a prospective cohort study, 146,665 adults were recruited from the general population in five areas of Cuba between 1996 and 2002. Participants were interviewed, measured (height, weight and blood pressure) and followed up by electronic linkage to Cuban national death registries to Jan 1 2017; 24,345 participants were resurveyed between 2006 and 2008. After excluding all with missing data or chronic disease at recruitment or, to further limit reverse causality, those who died in the first 5 years, Cox regression (adjusted for age, sex, education, smoking, alcohol and, where appropriate, BMI) was used to relate mortality rate ratios (RRs) at ages 35–79 years to BMI, SBP and diabetes. Correlations of baseline and resurvey values were used to corrected RRs for regression dilution, and thereby estimate associations with long-term average (“usual”) levels of SBP and BMI. Results After exclusions, there were 117,008 participants age 35–79 (mean age 52 [SD 12]; 55% women). At recruitment, mean SBP was 124 mm Hg (SD 15), mean BMI was 24.2 kg/m2 (SD 3.6) and 5% had diabetes; mean SBP and diabetes prevalence were both strongly related to BMI. Correlations of resurvey and baseline measurements were 0.48 for SBP and 0.60 for BMI. At ages 35–79 years, there were 3780 CVD deaths (1871 ischaemic heart disease [IHD], 766 stroke, and 1143 other). CVD mortality was positively associated with BMI (down to about 22–23 kg/m2; figure), SBP and diabetes: 10 kg/m2 higher usual BMI approximately doubled CVD mortality (RR 1.90, 95% CI 1.61–2.24), as did 20 mmHg higher usual SBP (2.03, 1.88–2.20), and a prior diagnosis of diabetes (2.18, 1.97–2.42). The associations were similar in men and women. Given these associations, about one quarter (27%) of CVD deaths in this study were attributable to these metabolic risk factors combined. Conclusion These associations differ to those reported from other parts of Latin America, and are more consistent with studies in Europe and North America, highlighting the need for many more large-scale prospective studies in low and middle income countries. This study provides direct evidence for the expected benefit on CVD mortality of addressing major metabolic risk factors in Cuba. As the levels of these metabolic risk factors are increasing in Cuba, so too is their importance as determinants of premature CVD death.

AbstractObjectiveProspective data on the associations between vitamin D intake and risk of CVD and all-cause mortality are limited and inconclusive. The aim of the present study was to investigate the associations between vitamin D intake and CVD risk and all-cause mortality in the Caerphilly Prospective Cohort Study.DesignThe associations of vitamin D intake with CVD risk markers were examined cross-sectionally at baseline and longitudinally at 5-year, 10-year and >20-year follow-ups. In addition, the predictive value of vitamin D intake for CVD events and all-cause mortality after >20 years of follow-up was examined. Logistic regression and general linear regression were used for data analysis.SettingParticipants in the UK.SubjectsMen (n452) who were free from CVD and type 2 diabetes at recruitment.ResultsHigher vitamin D intake was associated with increased HDL cholesterol (P=0·003) and pulse pressure (P=0·04) and decreased total cholesterol:HDL cholesterol (P=0·008) cross-sectionally at baseline, but the associations were lost during follow-up. Furthermore, higher vitamin D intake was associated with decreased concentration of plasma TAG at baseline (P=0·01) and at the 5-year (P=0·01), but not the 10-year examination. After >20 years of follow-up, vitamin D was not associated with stroke (n72), myocardial infarctions (n142), heart failure (n43) or all-cause mortality (n281), but was positively associated with increased diastolic blood pressure (P=0·03).ConclusionsThe study supports associations of higher vitamin D intake with lower fasting plasma TAG and higher diastolic blood pressure.

Background Arterial stiffness is an important predictor of cardiovascular events; however, indexes for measuring arterial stiffness have not been widely incorporated into routine clinical practice. This study aimed to determine whether the cardio‐ankle vascular index (CAVI), based on the blood pressure–independent stiffness parameter β and reflecting arterial stiffness from the origin of the ascending aorta, is a good predictor of cardiovascular events in patients with cardiovascular disease risk factors in a large prospective cohort. Methods and Results This multicenter prospective cohort study, commencing in May 2013, with a 5‐year follow‐up period, included patients (aged 40‒74 years) with cardiovascular disease risks. The primary outcome was the composite of cardiovascular death, nonfatal stroke, or nonfatal myocardial infarction. Among 2932 included patients, 2001 (68.3%) were men; the mean (SD) age at diagnosis was 63 (8) years. During the median follow‐up of 4.9 years, 82 participants experienced primary outcomes. The CAVI predicted the primary outcome (hazard ratio, 1.38; 95% CI, 1.16‒1.65; P <0.001). In terms of event subtypes, the CAVI was associated with cardiovascular death and stroke but not with myocardial infarction. When the CAVI was incorporated into a model with known cardiovascular disease risks for predicting cardiovascular events, the global χ 2 value increased from 33.8 to 45.2 ( P <0.001), and the net reclassification index was 0.254 ( P =0.024). Conclusions This large cohort study demonstrated that the CAVI predicted cardiovascular events. Registration URL: https://www.clinicaltrials.gov ; Unique identifier: NCT01859897.

Salt Consumption

Abstract Background/Introduction Salt intake is linked to hypertension but data on its association with incident cardiovascular events, especially among hypertensives, is limited. Purpose To examine the prospective association of different salt consumption levels with cardiovascular morbidity in a hypertensive population. Methods We followed 2130 hypertensive patients (age 57±12 years, 11.2% untreated) without a history of cardiovascular disease for a mean period of 5.3±3.3 years. At the baseline examination, salt intake was evaluated by a structured validated questionnaire. Accordingly, the study population was divided into three groups: hypertensives with a low (1079 patients, 51% of the population), a moderate (895 patients, 42%) and a high salt consumption (146 patients, 7%). During follow-up, patients underwent clinic visits at least yearly for management of hypertension and risk factors. The outcome studied was the composite of non-fatal cardiovascular events. Results The composite endpoint (19 strokes and 65 cases of coronary artery disease) occurred in 84 patients (3.9%). At baseline, increasing salt consumption was significantly associated with age, body mass index, office blood pressure and renal function. Unadjusted Cox regression analysis showed that, compared to the reference group, the risk for cardiovascular morbidity was similar in patients with moderate salt consumption (HR: 1.1, 95% CI: 0.71–1.77) but significantly higher in patients with high salt consumption (HR: 2.12, 95% CI: 1.09–4.38). This pattern was clearly sustained after adjusting for multiple risk factors including baseline blood pressure levels. Conclusions Among hypertensive patients, heavy salt consumption is associated with an increased cardiovascular risk, while moderate consumption does not affect patient outcome.

ObjectiveThis study was performed to explore the effects of visit-to-visit blood pressure variability (BPV) on cardiovascular events (CVEs) in people with various body mass indexes (BMIs).DesignProspective cohort study.SettingThe average real variability of systolic blood pressure (ARVSBP) was the indicator for visit-to-visit BPV. The participants were divided into three groups: normal weight, overweight and obesity. We further divided these groups into four subgroups based on the ARVSBP. A Cox regression model was used to calculate the HRs of the ARVSBP on CVEs in the same and different BMI groups. Additionally, a competitive risk model was used to calculate the HRs of the ARVSBP on CVEs in the same BMI group.ParticipantsIn total, 41 043 individuals met the inclusion criteria (no historical CVEs or tumours, no incidence of CVEs or tumours and no death during the four examinations) and had complete systolic blood pressure and BMI data.ResultsA total of 868 CVEs occurred. The cumulative incidence of CVEs increased as ARVSBP rose in both the normal weight and overweight groups. In same BMI groups, the risk of CVEs significantly increased as ARVSBP increased only in the normal weight group (highest quartiles of ARVSBP: HR (95% CI) 2.20 (1.46–3.31)). In the different BMI groups, the risk of CVEs in the ARVSBP subgroup in each BMI group was higher than that the least quintile of ARVSBP in the normal weight group (highest quartiles of ARVSBP in obesity: HR (95% CI) 2.28 (1.47–3.55)). The result of the competitive risk model did not change.ConclusionsAs BMI and ARVSBP increase, the risk of CVEs increases. However, the risk of visit-to-visit BPV on CVEs varies in different BMI groups, especially in people of normal weight.Trial registration numberCHiCTR-TNC1100 1489.
