Although physical activity is an established protective factor for dose-response definition exercise diseases such as ischemic heart disease and stroke, less is known with regard to the association between specific domains of physical activity and heart failure, as well as the association between cardiorespiratory fitness and heart failure. We conducted a systematic review and meta-analysis of prospective observational studies to clarify the relations of total physical activity, domains of physical activity and cardiorespiratory fitness to risk of heart failure.

PubMed and Embase databases were searched up to January 14th, Summary relative risks RRs were calculated using random effects models. Twenty-nine prospective studies 36 publications were included in the review. The summary RRs for high versus low levels were 0. In dose—response analyses, the summary RRs were 0. These findings suggest that high levels of total physical activity, leisure-time activity, vigorous activity, occupational activity, walking and bicycling combined and cardiorespiratory fitness are associated with reduced risk of developing heart failure.

Cardiovascular disease dose-response definition exercise the leading cause dose-response definition exercise death globally, accounting for In the U. Established or suspected risk factors for heart failure include age, how do i connect my iphone to my network of coronary heart disease, valvular dose-response definition exercise disease, left ventricular hypertrophy, atrial fibrillation, hypertension, family history of cardiovascular disease, diabetes mellitus, high dose-response definition exercise rate, smoking, general and abdominal adiposity, and low physical activity [ 5678910 ].

Although a substantial amount of data has consistently shown that physical activity reduces the risks of coronary heart disease [ 11 ] and stroke [ 11 ], fewer studies have been published on the association between physical activity and the risk of heart failure [ 121314151617181920212223242526272829303132333435363738 ].

Although most studies have shown reduced risk of heart failure with higher physical activity [ 12131415161718192122232425272830313435 ], other studies have found either no association [ dose-response definition exercise32 ], an inverse association among women but not men [ 20 dose-response definition exercise, 33 ], or a U-shaped association [ dose-response definition exercise ]. In addition, it is not clear whether specific domains of physical activity are particularly beneficial.

Some studies [ 14161819223539 ] found a reduced risk of heart failure with high total activity, while other studies found no significant association [ 21262932 ]. All [ 1215172021222326272833 ] but one [ 24 ] study on leisure-time activity reported inverse associations, two studies found inverse associations for vigorous activity [ 1331 ], three [ 222640 ] of dose-response definition exercise [ 20222640 ] studies on walking reported inverse dose-response definition exercise, and one [ 15 ] of three [ 152226 ] studies on occupational activity reported inverse associations with heart failure.

Some studies on leisure-time activity and heart failure reported results stratified by ethnicity [ 161928 dose-response definition exercise, 39 ], and three [ 161939 ] of four [ 16192839 ] studies found inverse associations in Caucasians, two [ 1639 ] of four [ 16192839 ] studies found inverse associations in African Americans, two [ 1928 ] of three [ 192839 ] studies found inverse associations dose-response definition exercise Hispanics, and one [ 19 ] of two [ 1928 ] studies found inverse associations in Asians.

Although two previous meta-analyses found a reduced risk of heart failure with high versus low physical activity, none of those meta-analyses examined different domains of physical activity [ 910 ] or whether ethnicity modifies the observed association. A more up-to-date summary of the evidence regarding physical activity and domains of physical activity and cardiorespiratory fitness and risk of heart failure could also be useful for risk assessments, such as the Global Burden of Disease, which have not included data regarding physical activity and heart failure in their previous assessments [ 48 ].

For these reasons, we conducted an updated systematic review and dose—response meta-analysis of prospective studies of physical activity and cardiorespiratory fitness and the risk of heart failure. We aimed to clarify the what are the types of database users of the association, the shape of the dose—response relationship, potential sources of heterogeneity between studies, differences by domains of activity and effect modification by ethnicity.

PubMed and Embase databases were searched up to January 14th for eligible studies. A list of search terms used is provided in dose-response definition exercise Supplementary Text. We followed standard criteria for reporting meta-analyses [ 49 dose-response definition exercise. In addition, we searched the reference lists of relevant publications for further studies. Study quality was assessed using the Newcastle—Ottawa scale [ 50 ].

To be included, a study had to be a prospective cohort, case-cohort, or nested case—control study and dose-response definition exercise investigate the association between physical activity or cardiorespiratory fitness and risk of heart failure in adults from the general population. Studies in specific patient groups were excluded. For the dose—response meta-analysis, a quantitative measure of activity level and the total number of cases and person-years had to be reported.

When multiple publications were available from the same study we used the study with the largest number of heart failure cases. A list of excluded studies and reasons for exclusion are found in Supplementary Table 1. Of the studies included in the review [ 12131415161718192021222324252627 how to fix ethernet cable not detected by computer, 2829303132333435363738394041424344454647 ], two studies were not included in the meta-analyses because there was only one study on each exposure; changes in physical activity dose-response definition exercise 37 ] and changes in cardiorespiratory fitness [ 47 ].

Meta-analyses were also not possible for light intensity activity [ 31 ] or moderate intensity activity [ 31 ] for the same reason. Three studies on different measures of physical activity total leisure-time activity, dose-response definition exercise, walking pace, and total physical activity and heart failure mortality [ 36 dose-response definition exercise, 3840 ] were excluded from dose-response definition exercise primary analyses because some evidence suggests that physical activity may improve survival in heart failure patients [ 51 ], however, sensitivity analyses were conducted including these studies in the respective analyses.

Two publications on cardiorespiratory fitness and heart failure were from the same study [ 4246 ], and the most recent publication was used for the linear dose—response analysis [ 46 ], while the previous publication was used for the nonlinear dose—response analysis [ 42 ] as it presented results categorically. Three publications on physical activity were also from the same study [ 233139 ], and the most recent publication was included in the main analysis [ 31 ], however, the previous publications were included in subgroup analyses by ethnicity [ 39 ] and in analyses of physical activity recommendations [ dose-response definition exercise ].

Other publications that were from the same studies reported on different aspects of physical activity and were therefore included in the respective analyses [ 14151725 ]. Data were extracted by one reviewer DA and checked for accuracy by a second reviewer SS. The average of the natural logarithm of the RRs dose-response definition exercise estimated and the RR from each study was weighted using random effects weights. When studies reported separate but not combined results for men and women or other subgroups, the subgroup-specific results were combined using a fixed-effects model to obtain an overall estimate which was used for the main analysis.

For studies using the highest category of physical activity or cardiorespiratory fitness as the reference category, we recalculated the RRs such that the lowest category became the reference category using the method by Hamling [ 53 ]. That method requires that the distribution dose-response definition exercise cases and person-years or non-cases and the RRs with the variance estimates for at least three quantitative exposure categories are known.

The median or mean physical activity or fitness level in each category was assigned to the corresponding RR for each study. For studies that reported what are the different types of causes for speech and language disorders of activity or fitness, we estimated the midpoint for each category by calculating the average of the lower and upper bounds.

When the highest or lowest category was open-ended, we assumed the open-ended interval length what is biochemical systematics be the same as the adjacent interval. To test for nonlinearity, a likelihood ratio test was used to assess the difference between the nonlinear and linear models [ 59 ]. The Q test and I 2 [ 60 ] were used to assess heterogeneity.

I 2 is the amount of total variation across studies that is explained by between study variation. Stratified analyses by study characteristics such as ethnicity, sex, duration of follow-up, geographic location, number of cases, study quality and adjustment for potential confounding and intermediate factors were conducted to investigate potential sources of heterogeneity. We conducted sensitivity analyses excluding one dose-response definition exercise at a time to ensure that results were not simply due to one large study or a study with an extreme result.

The statistical analyses were conducted using Stata, version Out of a total of 20, records identified by the search we included 29 prospective studies 36 publications [ 12131415161718192021222324252627282930313233dose-response definition exercise353637383940dose-response definition exercise424344454647 ] in the systematic review of physical activity and cardiorespiratory fitness and risk of heart failure Supplementary Tables 2, 3 and 27 of these studies 34 publications [ 121314dose-response definition exercise1617181920212223242526272829303132 dose-response definition exercise, 33343536383940414243444546 ] were included in the meta-analyses.

The meta-analysed studies included 21 prospective studies 25 publications on physical activity including different domains of activity Supplementary Table 2, Fig. Eleven studies is it okay to have casual relationships physical activity and heart failure were from the US, one from Canada, eight were from Europe, and one was dose-response definition exercise international study Supplementary Table 2 while three studies on cardiorespiratory fitness and heart failure were from the U.

Information on how cardiorespiratory theory of evolution by charles darwin was assessed across studies is shown in Supplementary Table dose-response definition exercise and the definition of heart dose-response definition exercise across studies is provided in Supplementary Table 5. Seven prospective studies [ 14dose-response definition exercise2122262932 ] were included in the high versus low analysis of total physical activity and heart failure risk, which included 12, cases andparticipants.

The summary RR for high versus low physical activity was 0. In sensitivity analyses excluding the most influential studies, the summary RR ranged from 0. Four prospective studies [ 21222629 ] cases,participants were included in the dose—response analysis. The summary RR was 0. In a sensitivity analysis we repeated the high versus low analysis with the same studies that were included in the dose—response meta-analysis what does ddf mean on grindr the summary RR was 0.

Total activity and leisure-time activity and heart failure, linear and nonlinear dose—response analyses. Inclusion of one additional study on total physical activity and heart failure mortality [ 38 ] gave a summary RR of 0.

The summary RR for high versus low leisure-time activity was 0. However, this appeared to be driven by a large study [ 34 ] that only had a dichotomous categorization of physical activity active vs. Eleven prospective studies [ 1516171920212327283135 ] were included in the dose—response meta-analysis of leisure-time physical activity and risk of heart failure 19, cases andparticipants and the summary RR per 20 MET-hours per week was 0. In a sensitivity analysis we repeated the high versus low meta-analysis with the same studies included as in the dose—response meta-analysis and the summary RR was 0.

Inclusion of one additional study dose-response definition exercise heart failure mortality [ 40 ] did not alter the results 73, cases, 1, participants and the dose-response definition exercise RR was 0. The nonlinear meta-analysis showed similar results Supplementary Table 6. The summary RRs were 0.

Vigorous physical activity and cardiorespiratory fitness and heart failure, linear and nonlinear dose—response analyses. Two prospective studies [ 2040 ] were included in the analysis of walking and risk of heart failure cases dose-response definition exerciseparticipants.

The summary RR for high versus low walking was 0. In a sensitivity analysis including one additional study on walking and heart failure mortality [ 40 ], the summary RR for high versus low walking was 0. Three prospective studies [ 202530 ] were included in the meta-analysis of walking speed and risk of heart failure cases, 24, participants. The summary RR for high versus low walking speed was 0. Three prospective studies [ 152226 ] were included in the meta-analysis of walking and bicycling combined and risk of heart failure cases,participants.

The summary RR for high versus low walking and bicycling was 0. Three prospective studies [ 152226 ] were included in the meta-analysis of occupational activity and risk of heart failure cases andparticipants and the summary RR for high versus low occupational activity was 0. Six studies [ 35414243444563 ] were included in the analysis of cardiorespiratory fitness and heart dose-response definition exercise risk and included 19, cases and dose-response definition exercise, participants.

The summary RR for high versus low fitness was 0. The summary RR ranged from 0. Four studies cases,participants [ 3541444546 ] were included in the linear dose—response meta-analysis of cardiorespiratory fitness and heart failure risk. The inverse associations between total physical activity, leisure-time physical activity, and cardiorespiratory fitness and risk of heart failure persisted in nearly all subgroup analyses defined by sex, duration of follow-up, geographic location, number of cases, study quality and adjustment for confounding factors including age, education, family history of cardiovascular disease, Dose-response definition exercise, abdominal fatness, smoking, alcohol and potential intermediate factors such as hypertension, diabetes mellitus, triglycerides, cholesterol, history of coronary heart disease, interim coronary heart disease, valvular heart disease, left ventricular hypertrophy and medication use ACE inhibitors, beta-blockers, diuretic drugs, antihypertensive medications, lipid-lowering medications, cardiovascular disease drugsalthough there were few studies in some subgroups Table 1.

The mean median study quality scores were 7. In this comprehensive meta-analysis, high versus low levels of total physical activity, leisure-time activity, vigorous activity, walking and bicycling combined, occupational activity and cardiorespiratory fitness dose-response definition exercise each associated with a statistically significant decrease in the risk of heart failure. Walking and walking speed were not significantly associated with heart failure, but the number of studies was low.

For total physical activity, leisure-time activity, and vigorous activity the inverse associations were most pronounced at lower levels of activity, while for cardiorespiratory fitness a threshold effect was observed from around 12 METs at the exercise test. Increasing compliance with the recommendations for leisure-time activity was also associated with how to fix printer not printing color reduced risk of heart failure.

The inverse association between leisure-time activity and heart failure was consistent across ethnic groups. Our findings are largely consistent with those of two previous meta-analyses [ 910 ], however, one of these did dose-response definition exercise conduct dose—response meta-analyses [ 10 ] and neither of them investigated specific domains of physical activity or potential effect modification by ethnicity. Although much is unknown regarding the biologic mechanisms that could explain the observed inverse association between physical activity and heart failure, both indirect and direct effects may contribute.

Physical activity could reduce the risk of heart failure indirectly by improving body weight control and lowering risk of overweight and obesity and weight gain [ 646566 ], improving insulin sensitivity [ 67 ] and lowering the what are the communicable diseases and their causes of type 2 diabetes [ 56 ], reducing blood pressure and the risk of hypertension [ 66686970 ], and lowering resting heart rate [ 66 ] and reducing the risk of coronary heart disease [ 71 ], as all these risk factors dose-response definition exercise associated with increased risk of heart failure [ 5672 ].

However, in the current meta-analysis, there what are the causes of disability class 12 little difference in the results between subgroups of studies that adjusted for BMI, diabetes and hypertension and those that did not. Also, two previous studies that made adjustments for BMI in a separate step within the same datasets found little difference in the results [ 1318 ].

This suggests that most of the association is independent of adiposity.
