Diabetes modifies the association of prehypertension with cardiovascular disease and all-cause mortality.

ABSTRACT: Prehypertension is a risk factor for cardiovascular disease (CVD) and all-cause mortality. However, it is unclear whether prehypertension combined with diabetes associate with a higher risk for cardiovascular disease and all-cause mortality. The purpose of this study was to explore the relationship between prehypertension and the risk of CVD and all-cause mortality was different among individuals with or without diabetes. In the prospective community-based Kailuan study, 67 344 participants without hypertension or a history of CVD at baseline (2006) were included. Prehypertension was defined as systolic blood pressure of 120-139 mmHg or diastolic blood pressure of 80-89 mmHg. The outcomes were CVD and all-cause mortality were followed up through December 31, 2017. We performed Cox proportional hazards models to evaluate the relationships between prehypertension and CVD and all-cause mortality by diabetes status. During a median follow-up of 11.03 years, 2981 CVD events and 4655 all-cause mortality occurred. After adjusting age, sex, and other factors, the associations of prehypertension with risk of CVD and all-cause mortality were significant in participants without diabetes (hazard ratio and 95% confidence interval: 1.54 [1.38-1.71] and 1.27 [1.17-1.38]), but not in participants with diabetes (1.20 [0.93-1.56] and 0.88 [0.73-1.07]). The interactions between prehypertension and diabetes for the risk of CVD and all-cause mortality were all significant (all p < .05). Prehypertension was only associated with an increased risk for CVD and all-cause mortality in non-diabetes participants. Diabetes modifies the relation of prehypertension with the risk of CVD and all-cause mortality.

Project description:BackgroundDiabetes is prevalent worldwide and is associated with cardiovascular disease (CVD). Furthermore, due to the insulin resistance, diabetic populations are vulnerable to liver fibrosis, which increases the risk of CVD. Fibrosis-4 index (FIB-4)-a non-invasive biomarker for liver fibrosis-is crucial in predicting CVD among patients with liver diseases. However, the association between FIB-4, death, and CVD in the US diabetic population has not yet been investigated.MethodWe conducted a cross-sectional study using the data from the National Health and Nutrition Examination Survey (NHANES) 1999-2008. The mortality status was obtained from the National Death Index through December 31, 2015. Participants were divided into survivor and mortality group to compare the basic characteristics. The association between FIB-4, death, and CVD was analyzed using the restricted cubic spline method and Cox proportional hazards models. In stratified analysis, Participants were stratified based on age, sex, BMI, hypertension, or eGFR respectively.ResultsThe participants (N = 3,471) were divided into survivor (N = 1,785) and mortality groups (N = 1,632), with the mortality group exhibiting significantly higher FIB-4 values. Moreover, the risk of all-cause mortality (HR 1.24; 95% CI, 1.17-1.32) and CVD mortality (HR 1.17; 95% CI, 1.04-1.31) increased with each FIB-4 SD increase after adjusting for all covariates. However, except for myocardial infarction, FIB-4 had no significant effect on the incidence of the other three CVD subtypes (congestive heart failure, coronary heart disease, and angina pectoris). In stratified analysis, we found that the effect of FIB-4 on CVD mortality was influenced by age, and FIB-4 is a risk factor for people older than 60 years (HR 1.14; 95% CI, 1.01-1.29).ConclusionUsing data from NHANES 1999-2008, FIB-4 was found to be associated with all-cause and CVD mortality in the diabetic population, and this association was significantly affected by age. However, FIB-4 only affected the incidence of myocardial infarction. Future work should investigate the association between FIB-4 and CVD in the diabetic population.

Project description:PurposeConduct a systematic umbrella review to evaluate the relationship of physical activity (PA) with all-cause mortality, cardiovascular mortality, and incident cardiovascular disease (CVD); to evaluate the shape of the dose-response relationships; and to evaluate these relationships relative to the 2008 Physical Activity Guidelines Advisory Committee Report.MethodsPrimary search encompassing 2006 to March, 2018 for existing systematic reviews, meta-analyses, and pooled analyses reporting on these relationships. Graded the strength of evidence using a matrix developed for the Physical Activity Guidelines Advisory Committee.ResultsThe association of self-reported moderate-to-vigorous physical activity (MVPA) on all-cause mortality, CVD mortality, and atherosclerotic CVD-including incident coronary heart disease, ischemic stroke and heart failure-are very similar. Increasing MVPA to guidelines amounts in the inactive US population has the potential to have an important and substantial positive impact on these outcomes in the adult population. The following points are clear: the associations of PA with beneficial health outcomes begin when adopting very modest (one-third of guidelines) amounts; any MVPA is better than none; meeting the 2008 PA guidelines reduces mortality and CVD risk to about 75% of the maximal benefit obtained by physical activity alone; PA amounts beyond guidelines recommendations amount reduces risk even more, but greater amounts of PA are required to obtain smaller health benefits; and there is no evidence of excess risk over the maximal effect observed at about three to five times the amounts associated with current guidelines. When PA is quantified in terms of energy expenditure (MET·h·wk), these relationships hold for walking, running, and biking.ConclusionsTo avoid the risks associated with premature mortality and the development of ischemic heart disease, ischemic stroke, and all-cause heart failure, all adults should strive to reach the 2008 Physical Activity Guidelines for Americans.
