Low risk for coronary heart disease (CHD) is defined by ATP III as a 10 year risk of <10%. There have been suggestions, however, that a 10 year CHD risk of 5–10% be considered as intermediate risk. The addition of carotid intima media thickness (CIMT) has been shown to improve CHD risk prediction when added to traditional risk factors (TRF) (age, gender, high density lipoprotein cholesterol, total cholesterol, diabetes, hypertension and cigarette smoking) in the ARIC study. We investigated the absolute event rates with and without the addition of CIMT to TRF in the ARIC study and determined the impact in the 0–10% risk group. Participants in the ARIC study (n=13145) without baseline CHD or stroke and with CIMT measurements available were included for this analysis. Using Cox proportional hazards models the participants were classified into various risk categories using TRF and further classified by sex specific CIMT (categorized as <25 th , 25 th to 75 th and >75 th percentile). The absolute event rates were then described in each group (table ). Over a mean follow up of 13.8 years, 1601 (12.2%) individuals had incident CHD events. Approximately 31% of these incident CHD events were in the 5–10% risk group which made up 28% of the study while only 16% of the incident CHD events occurred in the 0–5% risk group which made up 47% of the study population. The 5–10% group had event rates (13.7%) greater than the study average (12.2%), especially in those with thicker CIMT (>75 th percentile, event rate 17%), and greater event rates than those in the 0–5% risk group (4.1%) (table ). Given the notably higher observed CHD risk in the 5–10% group (especially in those with thicker CIMT) relative to the 0–5% group, the availability of safe, low cost lipid lowering medications and low risk tests such as ultrasound that may improve risk stratification, it may be time to evaluate the low risk group more carefully for cardiovascular preventive therapies.

Introduction: Low serum magnesium (Mg) levels have been associated with increased coronary heart disease (CHD) risk, likely acting through pathways such as hypertension, hyperglycemia or inflammation. An early (1998) ARIC paper evaluated this association, based on 319 events, and identified a sex-interaction whereby the inverse Mg-CHD association was stronger among women than men. Nearly 2,000 events have occurred since the prior publication. Hence, we sought to update the analysis. Hypothesis: We hypothesized serum Mg would be inversely and independently associated with long-term risk of CHD. Methods: A total of 14,465 ARIC study participants without CHD at visit 1 (baseline) were included. Serum Mg was measured at visit 1 (1987-89) and visit 2 (1990-92). Incident CHD events were identified through 2014 using annual telephone calls, hospital discharge lists and death certificates, and were adjudicated by physician review. Multivariable Cox proportional hazards regression models were used. Serum Mg was categorized into quintiles based on mean visit 1 and 2 concentrations. Based on prior findings in ARIC suggesting an interaction, we decided a priori to provide sex-stratified results. Results: Participants at baseline were mean±SD age 54±6y, 57% were women and 27% black. Serum Mg was 1.62±0.14 mEq/L overall, 1.62±0.14 mEq/L among women and 1.63±0.14 mEq/L among men. Over a median follow-up of 25 years, 1,939 CHD cases were identified. Overall, serum Mg was inversely and monotonically associated with CHD risk after adjustment for demographics, lifestyle factors and other CHD risk factors (Table, p-trend<0.001). The association was stronger among women (HR Q5 vs Q1=0.63) than men (HR=0.83), but the sex-interaction was not statistically significant (p>0.05). Conclusions: In this large community-based cohort, serum Mg was inversely associated with CHD risk. This association was slightly stronger among women than men. Further research is needed to understand if increasing Mg levels is a useful target for CHD prevention.

Introduction: Whole diet evaluated using dietary pattern is associated with systemic inflammation and coronary heart disease (CHD). Systemic inflammation also contributes to CHD risk. Genetic factors explain variations in whole diet, systemic inflammation, and CHD. However, it is unknown whether systemic inflammation is a mechanism linking whole diet to the long-term mortality risk from coronary heart disease independent of genes. Hypothesis: Systemic inflammation measured as plasma interleukin-6 levels medicates the association between whole diet and long-term mortality risk from coronary heart disease independent of genes. Methods: From the National Heart, Lung, and Blood Institute Twin Study, we included 554 white, middle-aged, veteran male twins (105 monozygotic and 109 dizygotic twin pairs; 65 monozygotic and 61 dizygotic unpaired twins). The twins were not on antihypertensive medication and had diastolic blood pressure below 105 mmHg at baseline (1969-1973) and did not have suspected acute inflammation [plasma levels of interleukin-6 (IL-6) above 10 pg/mL or C-reactive protein above 30 mg/L)]. Usual dietary data at baseline were collected through nutritionist-administered dietary history interview. Your-Choice American Heart Diet (YCARD) score was devised to quantitatively evaluate whole diet. Plasma interleukin-6 and C-reactive protein levels were measured with ELISA. Data on vital status and death causes were collected through death certificates until Dec 31, 2010. A frailty survival model was used to estimate various associations: overall (equivalent to the association in the general population), within-pair (independent of genes and environment common to co-twins), and between-pair (indicating influence of the common factors). We controlled for total caloric intake and known CHD risk factors including body mass index and modified Framingham Risk Score. Results: There were 75 CHD deaths during a 41-year follow-up (median follow-up of 34 years). The adjusted overall association between YCARD score and the CHD mortality risk was negative [partial coefficient for a 10-unit increment in the YCARD score: βo (95% confidence interval (CI)): -0.13 (-0.24, -0.02); hazard ratio (95% CI): 0.88 (0.78, 0.98)]. The partial regression coefficient was -0.02 [95% CI (-0.23, 0.19)] for the within-pair effect of YCARD (βw) and -0.12 [95% CI (-0.26, 0)] for the between-pair effect of YCARD (βb) in relation to CHD mortality risk. Additional adjustment for IL-6 led to a 15.4% reduction in the βo, a 100% increment in the βw, and a 16.7% reduction in the βb. Conclusions: Systemic inflammation measured as interleukin-6 mediates the association between whole diet and long-term coronary heart mortality risk, which is largely through genetic and environmental factors shared between co-twins.

The Impact

Background: Higher body-mass index (BMI) has been associated with increased risk for coronary heart disease (CHD) mortality but its association with incident CHD is less investigated, and data for women are limited. Methods: We examined the prospective relation between BMI and incident CHD (first CHD hospitalization or death) in 1.2 million women aged ≥50 years without prior CHD, who were recruited through a national breast screening programme in 1996 to 2001 and followed for an average of 9 years (48,842 events with 10.7 million person-years of follow-up). Absolute and relative risks (using Cox regression) associated with higher BMI were estimated. Results: After excluding the first 4 years of follow-up, there were 32,465 events (5.9 million person-years) including 3,345 CHD deaths. The adjusted relative risk per 5 kg/m 2 BMI difference was 1.24 [95% confidence interval (CI) 1.22 to 1.25]. CHD risk increased linearly across a wide range of BMI, with no apparent excess risk in the lower end of BMI distribution. The relation persisted after excluding current smokers or limiting cases to myocardial infarction only. For women in this cohort, the 20-year cumulative risk of CHD from age 55 to 74 years (95% CI) ranged from 9% (8 to10) to 18% (16 to 20) for women with BMI of 20 to 22.5 kg/m 2 and ≥35 kg/m 2 , respectively. Never smokers with BMI ≥35 kg/m 2 had comparable cumulative risk to current smokers with BMI of 20 to 22.5 kg/m 2 . Conclusion: In this large cohort of women, the impact of excess weight on CHD morbidity and mortality is substantial. Measures to prevent and control excess weight and other CHD risk factors are needed to help reduce CHD burden in women.

Abstract Background In the current guideline of the ESC, in patients with very high cardiovascular risk such as coronary heart disease (CHD) a treatment target for LDL-C &lt;1.4mmol/l and/or a halving of the initial value are defined. It is unclear whether these treatment targets are achievable with standard therapy including statins and/or ezetemibe. Methods The primary objective of this prospective, multi-centre register study was the question of the guidance-based adaptation and adherence to lipid-lowering therapy during and after a cardiac rehabilitation in 1,100 patients with CHD up to 12 months after discharge from the six rehabilitation clinics involved. Patients were included from 2016 to 2018. Results The median age of the 1,100 patients was 63.4±10.4 years, the mean BMI was 28.5±4.7kg/m2, and 24.1% of patients were female. 12.2% were active smokers, 91.6% reported dyslipoproteinemia, 33.9% suffered from diabetes mellitus and 86.5% from hypertension. The majority of patients were included with the main indications NSTEMI (31.6%), STEMI (29.6%) and after CABG surgery (26.4%). The proportion of patients treated with statins was more than 94% when admitted and discharged from the rehabilitation clinic, as well as in 3- and 12-months follow-ups. Approximately 9% of patients were treated with ezetemibe at baseline. On discharge from the rehabilitation clinic 23% of patients were treated with ezetemibe, which remains stable at 3 and 12 months. PCSK9 inhibitors were used in 0.1–0.3% of patients at all times. The adjustment of LLT during three week cardiac rehabilitation resulted in median LDL-C values of 2.27mmol/l (1.80/2.84) at baseline, 1.97mmol/l (1.57/2.47) on discharge (p&lt;0.001 compared to baseline), 1.94mmol/l (1.57/2.49) after three months and 1.94mmol/l (1.53/2.40) after 12 months. The proportion of patients with LDL-C &lt;1.4mmol/l was 9% at baseline, 15.7% on discharge (p&lt;0.001 compared to baseline), 15.6% at three-month follow-up and 15.1% at 12-month follow-up (Figure 1). Discussion In the context of cardiac rehabilitation, an effective adjustment of LLT is carried out, which resulted in a significant reduction of LDL-C. However, despite a high percentage of patients on statins and ezetemibe, the proportion of patients in the new target range &lt;1.4mmol/l was only achievable in a small percentage and the question arises whether these treatment targets can be achieved without additional administration of PCSK9 inhibitors in majority of patients with CHD.

Background: The relation of red meat to risk of coronary heart disease (CHD) is of great interest, but this is likely to depend on the foods to which red meat is compared. Objective: We investigated the associations between total, processed and unprocessed red meat consumption and CHD risk and also estimated the effects of substituting other protein sources for red meat. Methods: We prospectively followed 43,259 men in the Health Professionals Follow up Study (1986-2012) who had no known history of cancer or cardiovascular disease. Diet was assessed by a standardized and validated food frequency questionnaire that was updated every 4 years. Multivariate Cox models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) of CHD risk across categories of red meat consumption. Substitution analyses were done by comparing coefficients in models including alternative foods as continuous variables. Results: During 932,968 person-years of follow-up, we documented 4,148 incident CHD cases of which 1,680 were fatal CHD cases. After multivariate adjustment for dietary and nondietary risk factors, both total and processed red meat intake were associated with a modestly higher risk of CHD (HR for a one serving/day increment: 1.08; 95% CI, 1.01-1.14 for total and HR=1.13; 95% CI, 1.03-1.22 for processed red meat). Substitutions of 1-serving per day of other foods (including nuts, legumes, soy, whole grains, low- and high-fat dairy) for 1-serving per day of total red meat were associated with a 10%-47% lower CHD risk. Stronger inverse associations were observed between some of these substitutions for red meat and risk of fatal CHD [substituting nuts (-17%, -27% to -6%) or whole grains (-48%, -60% to -32%), and were more pronounced when replacing processed red meat. Conclusions: Our results suggest that red meat consumption, particularly processed red meat, is associated with higher risk of CHD. Substituting high-quality plant foods such as legumes, nuts, soy, and whole grains for red meat may substantially lower CHD risk.

Abstract Background A Genetic risk score for coronary artery disease (CAD) improves the ability of predicting coronary heart disease (CHD). It is unclear whether i) the use of a CAD genetic risk score is superior to the measurement of coronary artery calcification (CAC) for CHD risk assessment and ii) the CHD risk assessment using a CAD genetic risk score differs between men and women. Methods We included 4041 participants (age-range: 45–76 years, 1919 men) of the Heinz Nixdorf Recall study without CHD or stroke at baseline. A standardized weighted CAD genetic risk score was constructed using 70 known genetic variants. The risk score was divided into quintiles (Q1-Q5). We specified low (Q1), intermediate (Q2-Q4) and high (Q5) genetic risk groups. Incident CHD was defined as fatal and non-fatal myocardial infarction, stroke and coronary death. The association between the genetic risk score and genetic risk groups with incident CHD was assessed using Cox models to estimate hazard ratios (HR) and 95%-confidence intervals (CI). The models were adjusted by age and sex (Model1), as well as by established CHD risk factors (RF) and CAC (Model2). The analyses were further stratified by sex and controlled for multiple testing. Results During a median follow-up time of 11.6 ± 3.7 years, 343 participants experienced CHD events (219 men). Per-standard deviation (SD) increase in the genetic risk score was associated with 18% increased risk for incident CHD (Model1: p = 0.002) which did not change after full adjustment (Model2: HR = 1.18 per-SD (p = 0.003)). In Model2 we observed a 60% increased CHD risk in the high (p = 0.009) compared to the low genetic risk group. Stratifying by sex, only men showed statistically significantly higher risk for CHD (Model2: HR = 1.23 per-SD (p = 0.004); intermediate: HR = 1.52 (p = 0.04) and high: HR = 1.88 (p = 0.008)) with no statistically significant risk observed in women. Conclusion Our results suggest that the CAD genetic risk score could be useful for CHD risk prediction, at least in men belonging to the higher genetic risk group, but it does not outbalance the value of CT-based quantification of CAC which works independently on both men and women and allows better risk stratification in both the genders.

We examined the association of variation in the type 2 diabetes risk-conferringTCF7L2gene with the risk of incident coronary heart disease (CHD) among the lean, overweight, and obese members of the Atherosclerosis Risk in Communities (ARIC) Study cohort. Cox proportional hazard regression analyses were performed using a general model, with the major homozygote as the reference category. For 9,865 whites, a significant increase in the risk of CHD was seen only among lean (BMI<25 kg/m2) individuals homozygous for theTallele of theTCF7L2rs7903146 gene risk variant (hazard ratio 1.42; 95% CI 1.03,1.97;P=.01). No association was found among 3,631 blacks, regardless of BMI status. An attenuated hazard ratio was observed among the nondiabetic ARIC cohort members. This study suggests that body mass modifies the association of theTCF7L2rs7903146 T allele with CHD risk.

Abstract Background: The CADILLAC risk score was developed to identify patients at low risk for adverse cardiovascular events following ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PPCI). Methods: We performed a single center retrospective review of STEMI hospitalizations treated with PPCI from 2014 to 2018. Patients were stratified using the CADILLAC risk score into low risk group versus intermediate to high risk group. Patients presenting with cardiac arrest or cardiogenic shock were excluded from the study. The primary outcome was adverse clinical events during initial hospitalization. Secondary outcomes were adverse clinical events at 30 days and 1 year following index hospitalization. Results: The study included 314 patients. It was found that patients with a low CADILLAC score had significantly lower adverse clinical events compared to the intermediate-high CADILLAC score group (10/213 (4.7%) vs. 15/128 (11.7%), odds ratio = 0.37, 95% CI 0.16-0.85, p= 0.028). Additionally, patients with a low CADILLAC score had significantly lower adverse clinical event rates at 30 day and 1 year follow up. The mortality rate was 0% for patients defined at low risk by CADILLAC score during hospitalization, as well up to 1 year follow up. ROC curve predicting in hospital event rate showed CADILLAC (C=0.66, odds ratio 1.18; 95% CI 1.04 - 1.33; p=0.0064). Conclusion: Patients defined as low risk by the CADILLAC score following a STEMI were associated with lower event rates when compared to those with an intermediate-high CADILLAC score.

Aric Study

Several studies have demonstrated a positive relationship between vital exhaustion and incident coronary heart disease (CHD), but the association of exhaustion with recurrent cardiac events has not been established in large, epidemiologic studies. Vital exhaustion is considered the end-stage of prolonged psychological distress and is characterized by excessive fatigue, increased irritability, and a sense of demoralization. We assessed the hypothesis that vital exhaustion predicts recurrent cardiac events (myocardial infarction and CHD-related mortality) among middle-aged men and women with documented CHD. Participants were 589 black or white men and women (mean age = 59.8; range = 47 - 69 years) with a history of CHD at the 1990-1992 clinical examination of the ARIC Study. Vital exhaustion was measured at the same ARIC examination using the 21-item Maastricht Questionnaire, and scores were categorized into quartiles. Recurrent cardiac events were monitored in short term (0-5 years), mid- term (6-13 years), and long-term (14-19 years) follow-up. Cox proportional hazards regression models were adjusted for age, sex, race-center, educational level, body mass index, plasma LDL-and HDL-cholesterol levels, hypertension status, and pack-years of cigarette smoking. During short term follow-up, the risk for recurrent cardiac events among participants in the highest quartile of vital exhaustion was twice that of participants in the remainder of the sample (HR = 2.08; 95% C.I: 1.24 to 3.48). The risk was less strong but remained statistically significant in mid-term (HR = 1.77; 95% C.I: 1.26 to 2.48) and long-term (HR = 1.54; 95% C.I: 1.12 to 2.11) follow-up. In conclusion, vital exhaustion is positively associated with short-term and long-term risks for recurrent cardiac events among middle-aged men and women with established coronary heart disease, independent of the traditional biomedical risk factors.
