Objective: The independent prognostic value of prehypertension (preHTN) for incident coronary heart disease (CHD) remains unsettled. Using the REasons for Geographic And Racial Differences in Stroke (REGARDS) cohort study, we examined associations between preHTN and incident acute CHD and CVD death. Methods: REGARDS includes 30,239 black and white community-dwelling adults age 45 and older at baseline. Recruitment occurred from 2003-7, with baseline interviews and in-home data collection for physiologic measures. Follow-up is conducted by telephone every 6 months to detect events and deaths, which are adjudicated by experts. Systolic BP was categorized into <120 mmHg (n=4385), 120-129 mmHg (n=4000), 130-139 (n=2066), and hypertension was categorized into controlled (<140/90 mmHg on treatment) (n=8378), and uncontrolled (>140/90 mmHg) (n=5364). Incident acute CHD was defined as definite or probable myocardial infarction (MI) or acute CHD death. CVD death was defined as acute CHD, stroke, heart failure or other cardiovascular disease related. Cox proportional hazards models estimated the hazard ratios (HR) for incident CHD by BP categories, adjusting for sociodemographics and CHD risk factors. Results: The 23,393 participants free of CHD at baseline were followed for a median of 4.4 years. Mean age was 64.1, 58% were women and 42% were black. There was a significant interaction between sex and BP categories, therefore analyses were stratified by sex. There were 252 non-fatal and fatal acute CHD events among women and 407 among men. Among women, compared with SBP<120 mmHg, BP categories above SBP 120 mmHg were associated with incident CHD (adjusted HR for SBP120-129 mmHg=1.94 {95% CI 1.04-3.62]; SBP 130-139 mmHg=1.92 {0.95-3.87}; controlled HTN=2.16 {1.25-3.75}; uncontrolled HTN=3.25 {1.87-5.65}) in fully adjusted models. Among men, only uncontrolled HTN was associated with incident CHD (HR=1.55 {1.11-2.17}). Conclusion: In this sample, preHTN may be associated with incident CHD among women but not men.

D Dimer

Introduction: D-dimer, a marker of coagulation activation, has higher levels in blacks than whites and has been variably associated with stroke and coronary heart disease (CHD). Methods: REGARDS recruited 30,239 participants in their homes across the continental US between 2003-07; by design 55% were female, 41% black, and 56% lived in the southeast. In a case-cohort study, D-dimer was measured in 646 participants with incident stroke, 515 with incident CHD, and 1104 in a cohort random sample. D-dimer was log transformed and modeled per 1-unit increase. Cox models were used to determine the HR for vascular disease for D-dimer and the difference in HR (95% CI) by race and vascular disease calculated by bootstrapping with 1000 replicate samples and using the 2.5 and 97.5 percentiles of the distribution (see Table for model variables). Results: Median D-dimer was higher in blacks (0.45 mcg/mL; IQR 0.26, 0.85) than whites (0.38 mcg/mL; IQR 0.23, 0.69); p <0.001. D-dimer was higher with increasing age, female gender, diabetes, hypertension and prebaseline cardiovascular disease (all p <0.05). The table shows the HR of stroke and CHD by baseline D-dimer. In minimally-adjusted models, D-dimer was associated with both stroke and CHD. Accounting for Framingham stroke and CHD risk factors, D-dimer remained associated with CHD (HR 1.45; 95% CI 1.18, 1.79), but was marginally associated with stroke (HR 1.20; 95% CI 0.99, 1.45). The difference in the HR of D-dimer between CHD and stroke was 0.22 in the basic model and 0.25 in the Framingham model, but this difference was of marginal statistical significance (Table). There was no difference in the HRs for stroke or CHD for D-dimer in blacks compared to whites (Table). Discussion: The association of D-dimer with stroke appeared smaller than for CHD with similar associations by race. Findings suggest that hemostasis activation may play a greater role in pathogenesis of CHD than stroke. Further study is needed to confirm these findings and evaluate the association of D-dimer with different stroke subtypes.

Background: Increased attention has been given to pulse pressure (PP) as a potential independent risk factor of cardiovascular disease. We examined the relationship between PP and incident acute coronary heart disease (CHD). Methods: We used data from the REasons for Geographic And Racial Differences in Stroke (REGARDS) national cohort study of 30,239 black and white participants aged 45 years or older and enrolled between 2003 and 2007. Baseline data included a 45-minute interview and in-home visit during which blood pressure was assessed and recorded as the average of two measurements obtained after a 5 minute seated rest. PP (SBP-DBP) was classified into 4 groups (<45, 45-54, 54.1-64, >64.1 mmHg). Telephone follow-up occurred every six months for self or proxy-reported suspected events, triggering medical record retrieval and adjudication by experts. Cox-proportional hazards models examined the association of incident CHD with PP groups, adjusting for socio-demographic and clinical risk factors. Results: This analysis included 22,909 participants free of CHD at baseline, with mean age 64.7±9.4 years; 40.4%were black, 44.6% were male and they experienced a total of 515 incident CHD events over a mean 3.4 yrs of follow-up (maximum 6 years). In unadjusted analyses, compared with PP<45 mmHg, each higher PP group had incrementally higher hazard ratios (HR) for incident CHD (HR 1.28 {95% CI 1.02-1.60}, 2.05 {1.63-2.56}, 3.82 {3.08-4.74}, p<0.001 for linear trend). This relationship persisted after fully adjusting including SBP for the highest PP group (HR 0.96 {0.75-1.21}, 1.12 {0.86-1.46}, 1.51 {1.09-2.10}, p trend <0.0001). Conclusions: High PP was associated with incident CHD, even when accounting for SBP and numerous other CVD risk factors.

Statin Use

Dyslipidemia is a major risk factor for coronary heart disease (CHD) and is usually treated with statins. Few observational studies have examined associations between lipids and CHD in the era of widespread statin use. The objective of the current analysis was to contrast the association between serum lipids and incident coronary heart disease (CHD) among middle-aged adults before and after statin use became widespread. Methods: We analyzed data from 14,590 Atherosclerosis Risk In Communities (ARIC) study participants who were recruited in 1987-1989 (pre-statins), and 13,196 REasons for Geographic And Racial Differences in Stroke (REGARDS) study participants (9,578 not taking statins) who were recruited in 2003-2007 (post-statins). Our analysis was restricted to participants 45 to 64 years of age without a history of CHD at baseline. Total and HDL cholesterol (HDL-C) and fasting triglycerides (TG) were measured at baseline and used to calculate LDL-C, non-HDL-C, total-to-HDL-C ratio and total-to-TG ratio. Each lipid parameter was categorized into four levels based on REGARDS quartile cut-points. Results: In ARIC, participants with higher LDL-C were more likely to have diabetes and use antihypertensive medication, whereas these CHD risk factors were progressively less common at higher LDL-C in REGARDS participants not taking statins. Over a maximum 7 years of follow up, 513 and 278 incident CHD events occurred among ARIC and REGARDS participants, respectively. After multivariable adjustment, higher categories of each lipid marker (lower categories of HDL-C) were associated with a higher hazard ratio (HR) for CHD among ARIC participants, but not among REGARDS participants not taking statins (figure). No association between lipid markers and CHD was observed among REGARDS participants taking statins. DISCUSION: The current analysis suggests that the widespread preferential use of statins among high risk individuals may have obscured the association between lipids and incident CHD.

Introduction: Abnormal plasma lipid levels associate with coronary heart disease (CHD) risk. Race interaction for these associations are not established. Hypothesis: We hypothesized that the association of HDL, LDL, and triglyceride with CHD is stronger in whites versus blacks. Methods: The REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort recruited 30,283 black and white individuals aged 45+ from the contiguous U.S. from 2003-7. Participants were followed until December 31, 2016 for CHD events (i.e., myocardial infarction or CHD death), participants with history of CHD at baseline were excluded. Cox regression models were used to assess the association between baseline lipids and incident CHD events adjusting for traditional cardiovascular risk factors. Results: With 23,894 participants (57.8% white and 58.4% female, mean age 64.11± 9.32), over a median 9.9 years of follow-up, 1,487 CHD events occurred (615 among blacks). Overall, higher total Cholesterol, LDL cholesterol, and triglycerides were associated with increased risk of CHD in both blacks and whites with no evidence of a race interaction (Table 1). For HDL, the point estimate was more protective in whites (HR 0.90) than in blacks (HR 0.98), but the interaction was non-significant (p=0.15). However, when HDL was stratified into clinical categories (<40, 40-59, and ≥60), the reduction in point estimates was maintained among whites (HR 1.00, 0.88, and 0.74) but not among blacks (HR 1.00, 1.31, and 1.19) for HDL <40, 40-59, and ≥60 respectively, p-interaction 0.01. Conclusion: Total cholesterol, LDL, and triglycerides predict CHD risk equally in blacks and whites in the REGARDS study, however there is heterogeneity in the protective effect by race, especially when traditional clinical categories are used. In whites, higher HDL is associated with reduced risk, whereas in blacks the association is not maintained. These findings suggest that HDL levels are a more viable metric for white than blacks to predict CHD risk.
