- Abstract
Context: How best to identify families with premature myocardial infarction is unclear., Objective: We compared approaches to identify familial premature myocardial infarction in the general population using different familial hypercholesterolemia (FH) criteria and low-density lipoprotein (LDL) cholesterol cut-points., Design and Setting: Clinical and mutation criteria for FH and LDL cholesterol cut-points were applied for identification of familial premature myocardial infarction in 106,732 individuals from the Copenhagen General Population Study., Results: FH criteria identified 898 (13%) cases with familial premature myocardial infarction, leaving 5856 (87%) cases undetected. The ORs for familial premature myocardial infarction, compared with the respective remainder groups, were 4.7 (95% CI, 3.7 to 6.0) for clinical FH by Dutch Lipid Clinic Network criteria, 4.4 (4.0 to 4.7) for Simon Broome criteria, 2.1 (95% CI, 1.7 to 3.6) for Make Early Diagnosis to Prevent Early Death criteria, 2.1 (95% CI, 1.4 to 3.3) for FH mutation, and 1.4 (95% CI, 1.3 to1.6) for LDL cholesterol ≥5 mmol/L (193 mg/dL). For these risk groups, the sensitivity (true positive rate) for identification of familial premature myocardial infarction were 1.3%, 13%, 1.6%, 0.9%, and 7.1%, respectively. Compared with universal screening of a similar fraction of the population, the relative increase in sensitivity for these risk groups was 3.8-fold [fraction of population examined: 0.3%, 3.3-fold (4%), 2.0-fold (0.8%), 2.0-fold (0.4%), and 1.4-fold (5.3%), respectively]., Conclusion: Criteria for FH identify a small fraction of individuals with familial premature myocardial infarction in the general population. Actively identifying families with premature myocardial infarction would be of potential preventive importance, and this study provides data that could be used to choose the best method for such family identification., (Copyright © 2019 Endocrine Society.)

- Abstract
Context: Individuals with familial hypercholesterolemia (FH) have a high risk of coronary artery disease, but their risk of peripheral arterial disease (PAD) and chronic kidney disease (CKD) is unknown., Objective: In individuals with clinical FH, we tested the hypotheses (1) that the risks of PAD and CKD are elevated and (2) that low ankle-brachial index (ABI) and estimated glomerular filtration rate (eGFR) are associated with a high risk of myocardial infarction., Design and Setting: Prospective cohort study of the general population., Participants: A total of 106,172 individuals, of whom 7109 were diagnosed with FH., Main Outcome Measures: PAD, CKD, and myocardial infarction., Results: Compared with individuals with unlikely FH, multivariable adjusted ORs (95% CIs) of PAD were 1.84 (1.70 to 2.00) in those with possible FH and 1.36 (1.00 to 1.84) in individuals with probable/definite FH. For CKD, the corresponding ORs (95% CIs) were 1.92 (1.78 to 2.07) and 2.42 (1.86 to 3.26). Compared with individuals with unlikely FH and ABI >0.9, the multivariable adjusted hazard ratio (95% CI) of myocardial infarction was 4.60 (2.36 to 8.97) in those with possible/probable/definite FH and ABI ≤0.9. Compared with individuals with unlikely FH and eGFR ≥60 mL/min/1.73 m2, the corresponding value was 2.19 (1.71 to 2.82) in those with possible/probable/definite FH and eGFR <60 mL/min/1.73 m2., Conclusions: Individuals with clinical FH have increased risks of PAD and CKD, and low ABI and eGFR are associated with high risk of myocardial infarction. Consequently, individuals with FH should be screened for PAD and CKD, and ABI and eGFR may be used as prognostic tools in the management and treatment of FH to identify those at very high risk of myocardial infarction.

- Abstract
Background: We tested whether high remnant cholesterol is associated with high myocardial infarction risk, independent of whether an individual is normal weight, overweight, or obese., Methods: A total of 106216 individuals from the Copenhagen General Population Study were followed for up to 11 years, during which 1565 experienced a myocardial infarction. Individuals were grouped by clinically meaningful remnant cholesterol concentrations of <0.5 mmol/L (19 mg/dL), 0.5 to 0.99 mmol/L (19-38 mg/dL), 1.0 to 1.49 mmol/L (39-58 mg/dL), and ≥1.5 mmol/L (58 mg/dL), and by body mass index (BMI) of <18.5 kg/m
2 (underweight), 18.5 to 24.9 kg/m2 (normal weight), 25 to 29.9 kg/m2 (overweight), and ≥30 kg/m2 (obese)., Results: Median calculated remnant cholesterol was 0.40 mmol/L [interquartile range (IQR), 0.30-0.55 mmol/L] [15 mg/dL (12-21 mg/dL)] for underweight, 0.50 mmol/L (IQR, 0.37-0.71 mmol/L) [19 mg/dL (14-27 mg/dL)] for normal weight, 0.70 mmol/L (IQR, 0.49-1.00 mmol/L) [27 mg/dL (19-39 mg/dL)] for overweight, and 0.85 mmol/L (IQR, 0.61-1.20 mmol/L) [(33 mg/dL (24-46 mg/dL)] for obese individuals. On continuous scales, remnant cholesterol was positively correlated with BMI until reaching a plateau of approximately 1 mmol/L (39 mg/dL) at BMI >35 kg/m2 . R from an unadjusted linear regression for the correlation between calculated remnant cholesterol and BMI was 12%. Stepwise higher remnant cholesterol was associated with stepwise higher myocardial infarction risk in a similar pattern for normal weight, overweight, and obese individuals. When compared with individuals with remnant cholesterol <0.5 mmol/L (19 mg/dL), individuals with remnant cholesterol ≥1.5 mmol/L (58 mg/dL) had hazard ratios for myocardial infarction of 2.0 (95% CI, 1.3-3.2) for normal weight, 1.9 (95% CI, 1.4-2.6) for overweight, and 2.3 (95% CI, 1.4-3.5) for obese individuals. Directly measured remnant cholesterol increased 0.91 mmol/L (95% CI, 0.89-0.94 mmol/L) [35 mg/dL (34-36 mg/dL)] per 1 mmol/L (39 mg/dL) increase in calculated remnant cholesterol.2 from an unadjusted linear regression for the correlation between calculated remnant cholesterol and BMI was 12%. Stepwise higher remnant cholesterol was associated with stepwise higher myocardial infarction risk in a similar pattern for normal weight, overweight, and obese individuals. When compared with individuals with remnant cholesterol <0.5 mmol/L (19 mg/dL), individuals with remnant cholesterol ≥1.5 mmol/L (58 mg/dL) had hazard ratios for myocardial infarction of 2.0 (95% CI, 1.3-3.2) for normal weight, 1.9 (95% CI, 1.4-2.6) for overweight, and 2.3 (95% CI, 1.4-3.5) for obese individuals. Directly measured remnant cholesterol increased 0.91 mmol/L (95% CI, 0.89-0.94 mmol/L) [35 mg/dL (34-36 mg/dL)] per 1 mmol/L (39 mg/dL) increase in calculated remnant cholesterol., Conclusions: Remnant cholesterol and BMI were positively correlated; however, high remnant cholesterol was associated with higher myocardial infarction risk across the examined BMI subcategories, indicating that remnant cholesterol is a risk factor for myocardial infarction independent of overweight and obesity., (© 2017 American Association for Clinical Chemistry.)- Published

- Abstract
Objective: High lipoprotein(a) (Lp[a]) is the most common genetic dyslipidemia and is a causal factor for myocardial infarction (MI) and aortic stenosis (AS). We sought to estimate the population impact of Lp(a) lowering that could be achieved in primary prevention using the therapies in development., Approach and Results: We used published data from 2 prospective cohorts. High Lp(a) was defined as ≥50 mg/dL (≈20th percentile). Relative risk, attributable risk, the attributable risk percentage, population attributable risk, and the population attributable risk percentage were calculated as measures of the population impact. For MI, the event rate was 4.0% versus 2.8% for high versus low Lp(a) (relative risk, 1.46; 95% confidence interval [CI], 1.45-1.46). The attributable risk was 1.26% (95% CI, 1.24-1.27), corresponding to 31.3% (95% CI, 31.0-31.7) of the excess MI risk in those with high Lp(a). The population attributable risk was 0.21%, representing a population attributable risk percentage of 7.13%. For AS, the event rate was 1.51% versus 0.78% for high versus low Lp(a) (relative risk, 1.95; 95% CI, 1.94-1.97). The attributable risk was 0.74% (95% CI, 0.73-0.75), corresponding to 48.8% (95% CI, 48.3-49.3) of the excess AS risk in those with high Lp(a). The population attributable risk was 0.13%, representing a population attributable risk percentage of 13.9%. In sensitivity analyses targeting the top 10% of Lp(a), the population attributable risk percentage was 5.2% for MI and 7.8% for AS., Conclusions: Lp(a) lowering among the top 20% of the population distribution for Lp(a) could prevent 1 in 14 cases of MI and 1 in 7 cases of AS, suggesting a major impact on reducing the burden of cardiovascular disease. Targeting the top 10% could prevent 1 in 20 MI cases and 1 in 12 AS cases., (© 2016 American Heart Association, Inc.)

- Abstract
Context: It is unknown whether elevated lipoprotein(a) is causally associated with low-grade inflammation., Objective: We tested the hypothesis that elevated lipoprotein(a) is observationally and causally associated with low-grade inflammation together with aortic valve stenosis and myocardial infarction., Design and Setting: Using a multidirectional Mendelian randomization approach, we studied 100,578 individuals from the Danish general population with plasma levels of and/or genotypes known to affect levels of lipoprotein(a) and C-reactive protein (CRP), and using information regarding diagnosis of aortic valve stenosis and of myocardial infarction (MI) from registries., Results: Observationally, CRP increased by 29% (95% confidence interval [CI], 23-34) per 50-mg/dL increase in lipoprotein(a). However, two LPA single nucleotide polymorphisms (SNPs) and the kringle IV type 2 (KIV-2) genotype that were associated with 98, 95, and 68 mg/dL higher lipoprotein(a) levels were not causally associated with increased CRP levels. For aortic valve stenosis, a 1-SD increase in lipoprotein(a) levels was associated observationally with a multifactorially adjusted hazard ratio of 1.23 (95% CI, 1.06-1.41), with corresponding causal risk ratios of 1.38 (1.23-1.55) based on LPA SNPs and of 1.21 (1.06-1.40) based on LPA KIV-2 genotype. For myocardial infarction, corresponding values were 1.20 (1.10;1.31) observationally, and 1.18 (1.11;1.26) and 1.31 (1.22;1.42) causally, respectively. Observational hazard ratios for aortic valve stenosis and MI were similar after further adjustment for CRP levels., Conclusions: Elevated levels of lipoprotein(a) were not causally associated with increased low-grade inflammation as measured through CRP despite a causal association with increased risk of aortic valve stenosis and MI.

- Abstract
Background: Human immunodeficiency virus-infected individuals have increased risk of myocardial infarction (MI); however, the contribution from smoking and potentiating effects of HIV are controversial., Methods: From the Danish HIV Cohort Study and the Copenhagen General Population Study, we identified 3251 HIV-infected individuals and 13 004 population controls matched on age and gender. Data on MI were obtained from the National Hospital Registry and the National Registry of Causes of Death. We calculated adjusted incidence rate ratios (aIRR) for risk of MI and population-attributable fractions (PAF) of MI associated with smoking., Results: In never smokers, HIV was not associated with an increased risk of MI (aIRR, 1.01; 95% confidence interval [CI], .41-2.54). In previous and current smokers, HIV was associated with a substantially increased risk of MI (aIRR, 1.78; 95% CI, .75-4.24 and aIRR, 2.83; 95% CI, 1.71-4.70). The PAF associated with ever smoking (previous or current) was 72% (95% CI, 55%-82%) for HIV-infected individuals and 24% (95% CI, 3%-40%) for population controls. If all current smokers stopped smoking, 42% (95% CI, 21%-57%) and 21% (95% CI, 12%-28%) of all MIs could potentially be avoided in these 2 populations., Conclusions: Smoking is associated with a higher risk of MI in the HIV-infected population than in the general population. Approximately 3 of 4 MIs among HIV-infected individuals are associated with ever smoking compared with only 1 of 4 MIs among population controls. Smoking cessation could potentially prevent more than 40% of MIs among HIV-infected individuals, and smoking cessation should be a primary focus in modern HIV care., (© The Author 2015.

- Abstract
Objective: We tested the hypothesis that moderately elevated plasma creatinine levels and decreased levels of estimated glomerular filtration rate (eGFR) are associated with increased risk of myocardial infarction, ischemic heart disease, and early death in the general population., Methods: We studied 10,489 individuals with a plasma creatinine measurement and calculated eGFR from the Danish general population, of which 1498 developed myocardial infarction, 3001 ischemic heart disease, and 7573 died during 32 years follow-up., Results: Cumulative incidences of myocardial infarction and ischemic heart disease as a function of age increased with increasing levels of creatinine, and survival decreased (log-rank trends: <0.001). The median survival age was 78.7 (95%CI: 78.0-79.2) years for persons with creatinine levels <90th percentile, 78.1 (76.3-79.5) years for 90th-94th percentiles, and 74.8 (72.8-76.7) years for ≥95th percentile. Hazard ratios for myocardial infarction and plasma creatinine levels of 90th-94th percentiles and ≥95th percentile versus <50th percentile were 2.06 (95%CI: 1.67-2.56) and 1.90 (1.56-2.31) adjusted for gender and age, and 1.35 (1.09-1.68) and 1.11 (0.90-1.36) adjusted multifactorially, respectively. Corresponding estimates for creatinine and ischemic heart disease were 1.57 (1.33-1.85) and 1.64 (1.42-1.89) adjusted for gender and age, and 1.16 (0.98-1.37) and 1.11 (0.95-1.29) adjusted multifactorially. Finally, corresponding values for early death were 1.18 (1.06-1.32) and 1.43 (1.30-1.57), and 0.97 (0.87-1.09) and 1.13 (1.02-1.24), respectively. Low eGFR did not associate consistently with increased risk of these endpoints., Conclusion: In the general population, moderately elevated plasma creatinine was associated with increased risk of myocardial infarction, ischemic heart disease, and early death, while low eGFR was not., (Copyright © 2014 Elsevier Ireland Ltd.

Background: Plasma apolipoprotein B (apoB) is a composite measure of all apoB-containing lipoproteins causing atherosclerotic cardiovascular disease; however, it is unclear which fraction of risk is explained by cholesterol and triglycerides, respectively, in very low-density lipoproteins (VLDLs).Objectives: The authors tested the hypothesis that VLDL cholesterol and triglycerides each explain part of the myocardial infarction risk from apoB-containing lipoproteins.Methods: Nested within 109,751 individuals from the Copenhagen General Population Study, the authors examined 25,480 subjects free of lipid-lowering therapy and myocardial infarction at study entry. All had measurements of plasma apoB (quantitating number of apoB-containing lipoproteins) and cholesterol and triglyceride content of VLDL, intermediate-density lipoproteins (IDLs), and low-density lipoproteins (LDLs).Results: During a median 11 years of follow-up, 1,816 were diagnosed with myocardial infarction. Per 1-mmol/l higher levels, multivariable-adjusted hazard ratios for myocardial infarction were 2.07 (95% confidence interval [CI]: 1.81 to 2.36) for VLDL cholesterol, 1.19 (95% CI: 1.14 to 1.25) for VLDL triglycerides, 5.38 (95% CI: 3.73 to 7.75) for IDL cholesterol, and 1.86 (95% CI: 1.62 to 2.14) for LDL cholesterol. Per 1-g/l higher plasma apoB, the corresponding value was 2.21 (95% CI: 1.90 to 2.58). In a step-up Cox regression, risk factors for myocardial infarction entered by importance as VLDL cholesterol, systolic blood pressure, smoking, and IDL + LDL cholesterol, whereas VLDL triglycerides did not enter the model. VLDL cholesterol explained 50% and IDL + LDL cholesterol 29% of the risk of myocardial infarction from apoB-containing lipoproteins, whereas VLDL triglycerides did not explain risk.Conclusions: VLDL cholesterol explained one-half of the myocardial infarction risk from elevated apoB-containing lipoproteins, whereas VLDL triglycerides did not explain risk.
