Abstract
BACKGROUND AND AIMS Cardiovascular disease (CVD) aggregates in families and offspring with parental CVD may have adverse risk factor levels long time before the potential onset of CVD. We compared risk factor levels in offspring of parents with atherosclerotic CVD (ASCVD) and parents with no ASCVD at different parental ages at onset. METHODS The study included 5751 participants (median age: 50 years) of the Diet, Cancer and Health - Next Generations study. Measurements included blood pressure, body composition and lipid fractions. Information on parental ASCVD and age at disease onset was obtained through register linkage. Parental ASCVD was defined as myocardial infarction, ischemic stroke or peripheral artery disease occurring <70 years, prematurely (mothers: <65 years fathers: <55 years), divided into age categories or using a broader classification of CVD. Linear regression models using Generalized Estimating Equations were used for analysis. Analyses were adjusted for age, sex, education, smoking, alcohol intake, physical activity and some additionally for BMI. RESULTS Offspring with parental ASCVD had a higher blood pressure, waist circumference, BMI, visceral adipose tissue, percentage of body fat and non-HDL cholesterol levels, but not other lipid levels, compared to offspring with no parental ASCVD (all p < 0.01). Overall, the same patterns were observed for parental ASCVD occurring prematurely and using a broader CVD classification. CONCLUSIONS Offspring with parental ASCVD had a higher blood pressure, higher body composition measures and higher non-HDL cholesterol levels compared to offspring with no parental ASCVD. Findings were overall consistent across different classifications of parental ASCVD.

Ambroziak M, Niewczas-Wieprzowska K, Maicka A, Budaj A. Younger age of patients with myocardial infarction is associated with a higher number of relatives with a history of premature atherosclerosis. BMC Cardiovasc Disord 2020; 20:410. [PMID: 32912162 PMCID: PMC7488448 DOI: 10.1186/s12872-020-01677-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Accepted: 08/20/2020] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Premature coronary artery disease is one of the most pressing global issues in modern cardiology. The aim of the study was to investigate the role of family history of premature cardiovascular disease (CVD) in patients aged < 50 years with myocardial infarction (MI) compared to that in patients aged ≥50 years with MI and to that in young people without MI (no-MI < 50). METHODS The studied group (MI < 50) consisted of 240 patients aged 26-49 years with MI. The control groups consisted of 240 patients (MI ≥ 50) with MI aged 50-92 years and 240 healthy people aged 30-49 years without a history of MI (no-MI < 50). RESULTS There were statistically significant differences between the MI < 50 and MI ≥ 50 and no-MI < 50 groups regarding the family history of premature MI/ischaemic stroke and the percentage of patients with ≥2 relatives affected (10.8, 2.9, and 3.7%, respectively; p < 0.0001). There was a statistically significant difference in the patient age at the first MI occurrence among patients without a family history of premature CVD, those with 1 affected relative, and those with ≥2 affected first-degree relatives (56.6, 48.6 and 41.8 years, respectively) as well as those with affected first- and second-degree relatives (56.5, 50.7 and 47.0 years, respectively). CONCLUSIONS A younger age of patients with myocardial infarction is associated with a higher number of relatives with a history of premature MI/ischaemic stroke. Thus, the family history of premature atherosclerosis involving not only first- but also second-degree relatives seems to be a valuable factor in CVD risk evaluation in young people.

Abstract
BACKGROUND The LifeLines Cohort Study is a large three-generation prospective study and Biobank. Recruitment and data collection started in 2006 and follow-up is planned for 30years. The central aim of LifeLines is to understand healthy ageing in the 21st century. Here, the study design, methods, baseline and major cardiovascular phenotypes of the LifeLines Cohort Study are presented. METHODS AND RESULTS Baseline cardiovascular phenotypes were defined in 9700 juvenile (8-18years) and 152,180 adult (≥18years) participants. Cardiovascular disease (CVD) was defined using ICD-10 criteria. At least one cardiovascular risk factor was present in 73% of the adult participants. The prevalence, adjusted for the Dutch population, was determined for risk factors (hypertension (33%), hypercholesterolemia (19%), diabetes (4%), overweight (56%), and current smoking (19%)) and CVD (myocardial infarction (1.8%), heart failure (1.0%), and atrial fibrillation (1.3%)). Overall CVD prevalence increased with age from 9% in participants<65years to 28% in participants≥65years. Of the participants with hypertension, hypercholesterolemia and diabetes, respectively 75%, 96% and 41% did not receive preventive pharmacotherapy. CONCLUSIONS The contemporary LifeLines Cohort Study provides researchers with unique and novel opportunities to study environmental, phenotypic, and genetic risk factors for CVD and is expected to improve our knowledge on healthy ageing. In this contemporary Western cohort we identified a remarkable high percentage of untreated CVD risk factors suggesting that not all opportunities to reduce the CVD burden are utilised.

The Prognostic Value of Family History for the Estimation of Cardiovascular Mortality Risk in Men: Results from a Long-Term Cohort Study in Lithuania. PLoS One 2015; 10:e0143839. [PMID: 26630455 PMCID: PMC4667937 DOI: 10.1371/journal.pone.0143839] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2015] [Accepted: 11/10/2015] [Indexed: 12/31/2022] Open
Abstract
AIM To evaluate the additional prognostic value of family history for the estimation of cardiovascular (CVD) mortality risk in middle-aged urban Lithuanian men. METHODS The association between family history of CVD and the risk of CVD mortality was examined in a population-based cohort of 6,098 men enrolled during 1972-1974 and 1976-1980 in Kaunas, Lithuania. After up to 40 years of follow-up, 2,272 deaths from CVD and 1,482 deaths from coronary heart disease (CHD) were identified. Multivariate Cox proportional hazards models were used to estimate hazard ratios (HR) for CVD and CHD mortality. RESULTS After adjustment for traditional CVD risk factors, the HR for CVD mortality was 1.24 (95% CI 1.09-1.42) and for CHD mortality 1.20 (1.02-1.42) in men with first-degree relatives having a history of myocardial infarction (MI), compared to men without positive family history. A significant effect on the risk of CVD and CHD mortality was also observed for the family history of sudden cardiac death and any CVD. Addition of family history of MI, sudden death, and any CVD to traditional CVD risk factors demonstrated modest improvement in the performance of Cox models for CVD and CHD mortality. CONCLUSIONS Family history of CVD is associated with a risk of CVD and CHD mortality significantly and independently of other risk factors in a middle-aged male population. Addition of family history to traditional CVD risk factors improves the prediction of CVD mortality and could be used for identification of high-risk individuals.

Abstract
BACKGROUND Apolipoprotein B (ApoB) gene signal peptide insertion/deletion (SpIns/Del, I/D) and XbaI polymorphisms have been associated with susceptibility to myocardial infarction (MI). However, the results of studies on this association are still controversial. OBJECTIVE AND METHODS This study explored reports published from 1986 to 2008 regarding the association of ApoB gene SpIns/Del and XbaI polymorphisms with MI. A meta-analysis including 7169 participants from 19 individual studies was performed. The pooled odds ratios (ORs) and their corresponding 95% confidence intervals (95% CIs) were evaluated by fixed-effect or random-effect models. RESULTS A significant relationship between ApoB SpIns/Del gene polymorphism and MI was found under allelic (OR: 1.270, 95% CI: 1.090-1.480, P = 0.002), recessive (OR: 1.360, 95% CI: 1.130-1.630, P = 0.0009), dominant (OR: 1.091, 95% CI: 1.037-1.146, P = 0.001), homozygous (OR: 1.610, 95% CI: 1.330-1.950, P <0.00001) and heterozygous (OR: 1.081, 95% CI: 1.020-1.146, P = 0.009) genetic models. A marginal relationship between ApoB XbaI polymorphism and MI was found under a dominant genetic model (OR: 1.083, 95% CI: 1.004-1.168, P = 0.039). No significant association was detected under other genetic models (P >0.05). However, in the non-European subgroup analysis, increased MI risk emerged under all genetic models (P <0.05). CONCLUSION ApoB SpIns/Del gene polymorphism was positively associated with increased MI risk. D allele and DD genotype carriers might be predisposed to MI susceptibility. The ApoB XbaI gene polymorphism locus had a significant positive association with increased MI risk only in the non-European population. T allele and TT genotype carriers might be susceptible to MI in the non-European population. On the contrary, the ApoB gene XbaI restriction fragment length polymorphism was not associated with increased MI risk in the entire population, particularly in the European population.

A systematic review and meta-analysis. Int J Cardiol 2014; 179:409-16. [PMID: 25464496 DOI: 10.1016/j.ijcard.2014.11.017] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2014] [Revised: 10/27/2014] [Accepted: 11/03/2014] [Indexed: 11/27/2022]
Abstract
BACKGROUND Parental history of cardiovascular disease (CVD) is an established risk factor for the development of CVD in offspring. Several studies have suggested that a maternal transmission of CVD is more important for the development of CVD than paternal transmission. METHODS A systematic search and meta-analysis were conducted, using the Medline and Embase databases. Included were cohort, case-control and cross-sectional studies (n=26) focusing on the relation between paternal and maternal histories of cardiovascular disease and offspring CVD (myocardial infarction, stroke or cardiovascular mortality). The pooled estimates were calculated using a random-effects model. RESULTS The pooled OR of CVD in offspring having a positive paternal history of CVD compared to not having a positive parental history was 1.91 (95% CI 1.56-2.34; I(2)53%), the RR1.54 (95% CI 1.33-1.77; I(2)96%). The OR of a maternal history was 2.16 (95% CI 1.71-2.74; I(2)50%), RR1.59 (95% CI 1.38-1.84; I(2)90%). Regarding different age limits, a maternal history <50 years (3.15, 95% CI 2.18-4.55) and paternal history <55 years (2.82, 95% CI 2.25-3.54) were associated with the highest cardiovascular risk. Additional analyses for sons demonstrated an estimate for a positive paternal history of 1.55 (95% CI 1.39-1.71; I(2)74%) and 1.56 (95% CI 1.46-1.67; I(2)16%) for maternal history. For daughters, the estimate for paternal history was 1.48 (95% CI 1.26-1.74; I(2)73%) and 1.79 (95% CI 1.50-2.13; I(2)68%) for maternal history . CONCLUSIONS The conferred risk of CVD in offspring was not substantially different between positive paternal and maternal histories of CVD, the highest risk was observed for maternal history <50years. Since a positive parental history of CVD involves an increased cardiovascular risk, parental history inquiry is useful in clinical practice. No distinction has to be made whether the affected parent is the mother or the father.

Atherosclerosis 2014; 234:129-35. [PMID: 24650753 DOI: 10.1016/j.atherosclerosis.2014.02.018] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2013] [Revised: 01/20/2014] [Accepted: 02/18/2014] [Indexed: 12/31/2022]
Abstract
BACKGROUND Parental history of cardiovascular disease is a risk factor for first vascular events. It is unknown whether this also holds for subsequent events in patients with vascular disease. Also, the role of the location of parental vascular disease and the sex of the affected parent is unidentified. METHODS In a cohort of 4529 patients with symptomatic vascular disease enrolled in the Second Manifestations of Arterial Disease (SMART) Study, the relation between parental cardiovascular history under the age of sixty, sex of the parent, location of parental vascular disease (heart, brain, lower extremities) and subsequent myocardial infarction (MI), stroke, vascular death and peripheral artery disease (PAD) was determined by Cox-proportional hazard analyses. RESULTS During a median follow-up of 4.9 years (interquartile range 2.5-7.0), MI was experienced by 220 patients, stroke by 112, PAD by 297, whereas 371 patients died. A positive parental history of cardiovascular disease, without knowledge of vascular disease location and sex of that particular parent, was not associated with subsequent events (HR1.0; 95%CI 0.8-1.3). For specific types of parental history regarding sex and vascular location, having a father with a history of PAD was related to an increased risk of incident PAD (HR3.1; 95%CI 2.1-4.6). CONCLUSIONS A positive parental history of cardiovascular disease without information about vascular disease location and sex does not increase the risk of recurrent vascular events in patients with symptomatic vascular disease. Vascular patients with a father with PAD have an increased risk of subsequent peripheral artery disease compared with vascular patients without such a family history.

Abstract
Cardiovascular disease is the leading cause of death in women, contributing to one in three female deaths. Despite improvements in overall cardiovascular outcomes, substantial gender and ethnic disparities remain. In order to improve outcomes among women, we recommend the following: every woman should undergo risk stratification for short-term and lifetime cardiovascular risk given the substantial long-term risk of cardiovascular disease; modifiable cardiovascular risk factors in women should be modified to the greatest extent possible; and these factors include lipid abnormalities, hypertension, smoking, diabetes, obesity, physical inactivity and, possibly, inflammatory markers. The rate of decline in heart disease is slower for women than men, highlighting the need for gender-specific interventions to address the outcomes gap.

Abstract
BACKGROUND In clinical practice, individuals at increased risk of cardiovascular diseases (CVD) are identified on the basis of age, sex, smoking, blood pressure, and serum total and high-density lipoprotein cholesterol. We examined whether CVD risk prediction improved when obesity (body mass index ≥30 kg/m(2)) and premature (<70 years) parental myocardial infarction (MI) were added to the classical risk factor model. METHODS Risk factors were measured in 1993-97 in 12,818 participants (53% female) aged 35-65 in the Dutch MORGEN project. Cases of fatal and nonfatal CVD during 10 years of follow up were identified through record linkage. Classical risk factor equations, obtained by Cox proportional hazard analysis, were extended with obesity, paternal MI, and maternal MI. We calculated the net reclassification index (NRI), a measure for correct reclassification of subjects, to check improvement in risk prediction using 5 and 10% increments in absolute CVD risk. RESULTS A CVD event occurred in 280 men and 140 women. Obesity and maternal MI were positively and significantly related to total CVD after adjustment for classical risk factors (both hazard ratios ∼1.5). Adding obesity and parental MI to CVD risk prediction yielded a significant NRI of 4.5% in men and a non-significant NRI of 2.6% in women when 5% risk categories were used. For 10% categories, the NRIs were slightly larger (5.5% and 3.3%, respectively). The improvements in risk prediction were mainly due to obesity. CONCLUSION Modest improvements in CVD risk prediction can be obtained when obesity and, to a lesser extent, parental MI are added to the risk function.
