Background: Excess sedentary time (ST) is recognized as an important modifiable risk factor for coronary heart disease (CHD). However, whether the associations of genetic susceptibility with CHD incidence can be modified by replacing wearable‐device‐measured ST with physical activity (PA) is unknown. Objectives: To examine the associations of wearable‐device‐measured ST replaced by PA with incident CHD across strata of genetic susceptibility. Methods: This study included 77,500 White British (57% female) with valid wrist‐worn accelerometry and without prevalent CHD/stroke from UK Biobank. Genetic susceptibility to CHD was quantified through weighted polygenic risk scores for CHD based on 300 single‐nucleotide polymorphisms. Wrist‐worn accelerometer data were used to derive ST, light PA, and moderate‐to‐vigorous PA (MVPA). Results: Reallocation of 60 min/day of ST into the same amount of MVPA was associated with approximately 9% lower relative risk of CHD for all participants and across strata of genetic risk: replacement of 1 min/day of ST associated with <1% lower relative risk of CHD. No evidence of interaction (p: 0.784) was found between genetic risk and ST for CHD risk. Reallocating 60 min/day of ST into the same MVPA time was associated with greater absolute CHD risk reductions at high genetic risk (0.27%) versus low genetic risk (0.15%). Conclusions: Replacing any amount of ST with an equal amount of MVPA time is associated with a lower relative risk of CHD, irrespective of genetic susceptibility to CHD. Reductions in CHD absolute risk for replacing ST with MVPA are greater at high genetic risk versus low genetic risk. [ABSTRACT FROM AUTHOR]

Efferocytosis, the process of engulfing and removing apoptotic cells, is attenuated in vulnerable plaques of advanced atherosclerosis. T‐cell immunoglobulin and mucin domain 4 (TIMD4) is a recognition receptor protein for efferocytosis that has been implicated in atherosclerosis mouse models. However, the role of serum‐soluble TIMD4 (sTIMD4) in coronary heart disease (CHD) remains unknown. In this study, we analyzed serum samples collected from two groups: Group 1 (36 healthy controls and 70 CHD patients) and Group 2 (44 chronic coronary syndrome [CCS]) and 81 acute coronary syndrome [ACS] patients). We found that sTIMD4 levels in patients with CHD were significantly higher than those in healthy controls and were also higher in ACS than in CCS patients. The area under the receiver operating characteristic curve was 0.787. Furthermore, our in vitro results showed that low‐density lipoprotein/lipopolysaccharide activated p38 mitogen‐activated protein kinase, which in turn enhanced a disintegrin and metalloproteinase 17, resulting in increased secretion of sTIMD4. This impairment of macrophage efferocytosis promoted inflammation. Thus, this study is not only the first identification of a potential novel biomarker of CHD, sTIMD4, but also demonstrated its pathogenesis mechanism, providing a new direction for the diagnosis and treatment of CHD.

Background: Sedentary behavior has been recognized as a strong risk marker of coronary heart disease (CHD). However, whether the association of time spent sedentary with CHD is independent of genetic susceptibility to CHD is currently unknown. Purpose: This study examined the interplay of genetic susceptibility to CHD and two prevalent types of screen-based sedentary behavior (television [TV] viewing and computer use) relative to CHD incidence. Methods: We analyzed data from 374,055 white British participants of UK Biobank without CHD/stroke at baseline. Each individual���s genetic risk for CHD was assessed using weighted polygenic risk scores, calculated by summing 300 genome-wide significant, independent risk alleles, multiplied by their corresponding effect estimates. TV viewing and computer use were assessed through touch-screen questionnaires. CHD incidence (n= 9,562) was adjudicated over a median 12.1-year follow-up (i.e. 4,495,844 person-years). Cox regression models with age as the underlying timescale were fit. Results: Compared with ���4hours/day of TV viewing, the hazard ratio (HR) of CHD was 0.83 (95% confidence interval [CI]: 0.78-0.89) for ���1hour/day of TV viewing and 0.93 (0.89-0.98) for 2-3hours/day of TV viewing, after adjusting for all confounders including genetic risk for CHD. The HR of CHD for middle and high genetic risk was 1.45 (1.37-1.53) and 2.08 (1.98-2.19), respectively, compared with low genetic risk, after adjustment for all confounders. Decreased CHD was observed for ���1hour/day of TV viewing at high and middle genetic risk and 2-3hours/day of TV viewing at low genetic risk: no evidence of multiplicative interaction between genetic risk and TV viewing (p-value: 0.593). Estimates of the population attributable fractions (PAF) suggested that 11.4% (95% CI: 6.8%-15.7%) of the population risk of CHD could be prevented if TV viewing time were reduced from ���2hours/day to ���1hour/day. The PAF values were relatively larger for middle-to-high genetic risk than for low genetic risk, although the confidence intervals were wide and overlapping. No evidence of associations was observed for computer use. Conclusions: Reduced TV viewing time was associated with decreased CHD risk independently of genetic risk. Relatively stronger associations were found for lower TV viewing time at high and middle genetic risk. The results suggest that individuals with high genetic susceptibility may receive greater CHD-risk reducing benefits from a given reduction in TV viewing time.
