Long-Term Evolution of Premature Coronary Artery Disease

BackgroundThe long-term evolution of premature coronary artery disease (CAD) is unknown. ObjectivesThe objective of this study was to describe the evolution of coronary atherosclerosis in young patients and identify the risk factors of poor outcomes. MethodsParticipants age ≤45 years with acute or stable obstructive CAD were prospectively enrolled and followed. The primary endpoint was all-cause death, myocardial infarction (MI), refractory angina requiring coronary revascularization, and ischemic stroke. ResultsEight hundred-eighty patients with premature CAD were included. They were age 40.1 ± 5.7 years, mainly men, smokers, with a family history of CAD or hypercholesterolemia. At baseline presentation, 91.2% underwent coronary revascularization, predominantly for acute MI (78.8%). Over a follow-up of 20 years, one-third (n = 264) of patients presented with a total of 399 ischemic events, and 36% had at least a second recurrent event. MI was the most frequent first recurrent event (n = 131 of 264), mostly related to new coronary lesions (17.3% vs. 7.8%; p = 0.01; hazard ratio [HR]:1.45; 95% confidence interval [CI]: 1.09 to 1.93 for new vs. initial culprit lesion). All-cause death (n = 55; 6.3%) occurred at 8.4 years (median time). Ethnic origin (sub-Saharan African vs. Caucasian, adjusted hazard ratio [adjHR]: 1.95; 95% CI: 1.13 to 3.35; p = 0.02), inflammatory disease (adjHR: 1.58; 95% CI: 1.05 to 2.36; p = 0.03), and persistent smoking (adjHR: 2.32; 95% CI: 1.63 to 3.28; p < 0.01) were the strongest correlates of a first recurrent event. When considering all recurrent events, the same factors and Asian ethnicity predicted poor outcome, but persistent smoking had the greatest impact on prognosis. ConclusionsPremature CAD is an aggressive disease despite the currently recommended prevention measures, with high rates of recurrent events and mortality. Ethnicity and concomitant inflammatory disease are associated with poor prognoses, along with insufficient control of risk factors.

Investigating Coronary Artery Disease methylome through targeted bisulfite sequencing

BackgroundGene environment interactions leading to epigenetic alterations play pivotal role in the pathogenesis of Coronary Artery Disease (CAD). Altered DNA methylation is one such epigenetic factor that could lead to altered disease etiology. In this study, we comprehensively identified methylation sites in several genes that have been previously associated with young CAD patients. MethodsThe study population consisted of 42 healthy controls and 33 young CAD patients (age group <50 years). We performed targeted bisulfite sequencing of promoter as well as gene body regions of several genes in various pathways like cholesterol synthesis and metabolism, endothelial dysfunction, apoptosis, which are implicated in the development of CAD. ResultsWe observed that the genes like GALNT2, HMGCR were hypermethylated in the promoter whereas LDLR gene promoter was hypomethylated indicating that intracellular LDL uptake was higher in CAD patients. Although APOA1 did not show significant change in methylation but APOC3 and APOA5 showed variation in methylation in promoter and exonic regions. Glucokinase (GCK) and endothelial nitric oxide synthase 3 (NOS3) were hyper methylated in the promoter. Genes involved in apoptosis (BAX/BCL2/AKT2) and inflammation (PHACTR1/LCK) also showed differential methylation between controls and CAD patients. A combined analysis of the methylated CpG sites using machine learning tool revealed 14 CpGs in 11 genes that could discriminate CAD cases from controls with over 93% accuracy. ConclusionsThis study is unique because it highlights important gene methylation alterations which might predict the risk of young CAD in Indian population. Large scale studies in different populations would be important for validating our findings and understanding the epigenetic events associated with CAD.

Pathology of atherosclerotic coronary artery disease in the young Indian population

Atherosclerotic coronary artery disease (CAD) is of great concern in young adults because of its potential to cause great incapacitation. This arena of cardiology has gained importance in South Asian countries, particularly India due to increased prevalence that is related to traditional risk factors, altered life styles and inherent risk factors. In this study, we sought to evaluate, at autopsy, the pathology of atherosclerotic CAD in young patients with ischemic heart disease (IHD). A 10-year retrospective autopsy-based study was carried out in a large tertiary-care centre and patients aged ≤45 years with IHD were selected. Out of 545 autopsied cases of IHD, 95 patients (17.4%) were young. Among these 95 patients, 84 (88.4%) had IHD related to atherosclerotic CAD; the youngest patient was 18 years old. Predictably there was sole involvement of left anterior descending artery and the presence of fibrous plaques. Irrespective of the plaque morphology, the commonest complication was thrombosis produced by plaque erosion seen in 36.9% of patients. Acute coronary insufficiency was noted in 52 patients (61.9%), while healed infarctions were surprisingly noted in 28 patients (33.3%). Screening for IHD in the young population may help to improve prognosis by detecting subclinical disease, although more studies are necessary to establish reference limits for this young population. Additional research must also focus on treatment concerns that are specific to young patients.

Application of expanded genetic analysis in the diagnosis of familial hypercholesterolemia in patients with very early-onset coronary artery disease

BackgroundPatients with monogenic familial hypercholesterolemia (FH) have high risk for coronary artery disease (CAD). A recent FH Expert Panel suggested that FH was underdiagnosed and undertreated which needs early diagnosis. Moreover, the proportion of DNA-confirmed FH patients hospitalized with very early-onset (≤ 35 years) CAD remains uncertain.MethodsOne hundred and five patients with age ≤ 35 years and LDL-C ≥ 3.4 mmol/L were tested for 9 genes (LDLR, APOB, PCSK9, APOE, STAP1, LIPA, LDLRAP1, ABCG5/8). Dutch Lipid Clinic Network (DLCN) and Simon Broome (SB) criteria for FH were also performed.ResultsThe prevalence of genetically confirmed FH was 38.1% (n = 40) in 105 patients. DLCN categorized 26.7% patients to probable and definite FH while SB identified 17.1% of patients with possible to definite FH. Twenty-five (62.5%) and seventeen (42.5%) patients with pathogenic mutations were undiagnosed according to SB and DLCN criteria. FH variant carriers, especially homozygotes, had significantly higher plasma LDL-C levels. The best LDL-C threshold for genetically confirmed FH was 4.56 mmol/L in the present study.ConclusionsFH is really a common cause for very young CAD patients (≤ 35 years) with a 38.1% of causative mutations in China and best LDL-C threshold for predicting mutations was 4.56 mmol/L. The underdiagnostic rate of clinical criteria was around 42.5–62.5%, suggesting that the expanded genetic testing could indeed promote the diagnosis of FH.

Increased prevalence of subclinical coronary atherosclerosis in young patients with ankylosing spondylitis

Introduction There is substantial evidence that spondyloarthropathies, such as ankylosing spondylitis (AS) and psoriatic arthritis (PsA), may increase cardiovascular risk. Objectives The study aimed to compare development of atherosclerotic lesions in coronary arteries between patients with AS and individuals without rheumatic dise ases. Patients and methods A total of 37 adult patients with AS (mean [SD] age, 40.4 [9.6] years; men, 26 [70.3%]), with disease duration of less than 10 years were enrolled. The control group consisted of 76 participants without rheumatic diseases. Controls were matched for age, sex, history of hypertension, dyslipidemia, and smoking status. Coronary computed tomography angiography was performed in both groups. Results Atherosclerotic lesions in the coronary arteries were present in 18 patients (48.7%) with AS compared with 20 controls (26.3%) (P = 0.02). Univariate analysis performed in the AS group demonstrated an association between the presence of lesions and age (P = 0.02), hypertension (P = 0.003), and dyslipidemia (P = 0.001). The multivariable logistic regression analysis showed a significant association between coronary atherosclerosis and hypertension (P = 0.008) and with dyslipidemia (P = 0.001). The average plaque burden was higher in patients with AS than in controls (mean [SD], 42.2% [4.7%] vs 36.5% [3.1%], P <0.0001). Conclusions Atherosclerotic plaques in the coronary arteries were significantly more prevalent in patients with AS. A strong association was demonstrated between atherosclerotic lesions and age, hypertension, and dyslipidemia. Our results confirm the need for cardiovascular risk assessment in patients with AS and cardiovascular prevention, if indicated.

A preliminary study of the association between the ABCA1 gene promoter DNA methylation and coronary artery disease risk.

Coronary artery disease (CAD) is a common health problem in Iranian population. ATP binding cassette transporter A1 (ABCA1) plays central role in the efflux of the cholesterol from peripheral tissues back to liver. Inactivation of ABCA1 by epigenetic change such as DNA methylation may contribute to the development of CAD. The present study investigated the association between promoter DNA methylation status of ABCA1 with the development and severity of CAD. Our study population consisted of 110 angiographically documented CAD patients and 110 controls. The severity of CAD was determined based on the number of stenotic vessels showing more than 50% stenosis. Promoter DNA methylation status of ABCA1 was determined by methylation specific PCR. Lipid profile was determined by routine colorimetric methods. Results showed that the frequency of ABCA1 DNA methylation was significantly higher in CAD group as compared with control group (16.36% vs 5.45%; P=0.015). Also, the methylation frequency of ABCA1 gene was significantly higher in older CAD patients as compared with younger CAD patients (P=0.038). No association was seen between plasma lipid concentration and the promoter DNA methylation status of ABCA1 (P>0.05). Also, the association between the severity of CAD and methylation of ABCA1 gene was not significant (P>0.05). In conclusion the current study indicated ABCA1 DNA methylation as a significant risk factor for development but not severity of CAD. Also, predisposition to the development of CAD by ABCA1 gene DNA methylation was independent of plasma lipid concentration.

Expanded Genetic Analysis Facilitates the Definitive Diagnosis of Familial Hypercholesterolemia in Patients with Very Early-Onset Coronary Artery Disease

Background: Familial hypercholesterolemia (FH) is the one of major cause of coronary artery disease (CAD), especially for young patients. A recent FH Expert Panel suggested that FH was underdiagnosed and undertreated which needs early diagnosis. Methods: One hundred and five patients with age ≤35 years and LDL-C ≥ 3·4 mmol/L were evaluated for 9 genes (LDLR, APOB, PCSK9, APOE, STAP1, LIPA, LDLRAP1, ABCG5/8). Dutch Lipid Clinic Network (DLCN) and Simon Broome (SB) criteria for FH were also performed. Findings: The prevalence of genetically confirmed FH was 38·1% in 105 patients (LDLR, APOB, PCSK9, STAP1, homozygote and two mutations in 15, 7, 2, 1, 4, and 11 patients respectively). DLCN categorized 26·7% patients to probable and definite FH while SB identified 17·1% of patients with possible to definite FH. Twenty-five (62·5%) and seventeen (42·5%) patients with pathogenic mutations were undiagnosed according to SB and DLCN criteria. FH variant carriers, especially homozygote, had significantly higher plasma LDL-C levels. The best LDL-C threshold for genetically confirmed FH was 4·56 mmol/L in the present study. Interpretation: FH is really a common cause for very young CAD patients (≤ 35 years) with a 38·1% of causative mutations in China and best LDL-C threshold for predicting mutations was 4·56 mmol/L. The underdiagnostic rate of clinical criteria was around 42·5%-62·5%, suggesting that the expanded genetic testing could indeed promote the diagnosis of FH. Funding: This work was supported by the Capital Health Development Fund (201614035) and CAMS Major Collaborative Innovation Project (2016-I2M-1-011). Declaration of Interest: The authors declared no conflict of interest. Ethical Approval: The study protocol complied with the Declaration of Helsinki and was approved by hospital’s ethical review board (FuWai Hospital & National Center for Cardiovascular Diseases, Beijing, China). Informed written consents were obtained from all patients enrolled in this analysis.

Sex-dependent effects of diabetes mellitus on the revascularization rate in mid-term follow up of young patients with coronary artery disease

AimsWe investigated the association between Type-2 diabetes mellitus (DM) and the need for revascularization at a 5-year follow-up of young coronary artery disease patients and the role of sex in this regard. MethodsAmong 1121 young (males≤45, and females≤55years) patients (female: 49.7%) from Tehran Heart Center's Premature Coronary Atherosclerosis Cohort, 371(33.1%) had diabetes prior to angiography. Revascularization was considered as either percutaneous coronary intervention or coronary artery bypass graft surgery. ResultsThe mean follow-up duration was 57.67±22.43months. In the univariable analysis, diabetics were at a significantly higher risk of revascularization than nondiabetics (Sub-distributional Hazard Ratio [SHR]=1.843, P value<0.001). There was no association between DM and revascularization among men (SHR=1.232, P value=0.508). In contrast, women with DM had threefold more revascularization risk than women without DM (SHR=3.519, P value<0.001). After adjustment for confounding factors, the risk of revascularization in diabetics compared to nondiabetics increased to 2.139 fold (95% CI=1.473, 3.108) among the whole subjects, remained nonsignificant among men, and increased significantly to 3.725 fold (95% CI=2.067, 6.725) in women. ConclusionsOur data showed that in women with premature CAD, but not in men, DM may have a significant role in emerging revascularization during a mean follow-up of 5years.

Stress echocardiography: An overview for use in pediatric and congenital cardiology.

Currently, the role of stress echocardiography primarily resides in diagnosing acquired coronary artery disease (CAD) in adults. Besides an increasing concern for traditional CAD in young patients due to obesity and other chronic pediatric diseases, there is also a growing population of adolescents and young adults with "at risk" coronary arteries due to: reimplanted coronaries in congenital heart disease, anomalous origin of the native coronary arteries, coronary abnormalities in Kawasaki's disease, and posttransplant coronary vasculopathy. Stress echocardiography is well suited for routine screening and monitoring in these patients. Also, due to the ability of stress echocardiography to provide real-time cardiac imaging, it is useful in areas beyond coronary ischemia. Utilizing Doppler derived velocities and pressure gradients, one is able to further evaluate and risk-stratify patients with valvular heart disease. In addition, stress echocardiography is useful in evaluating other areas including ventricular and coronary reserve. The benefits of stress echocardiography are it is: readily available, portable, and relatively cheap. It can be performed without sedation or radiation exposure which becomes very important in younger patients that require periodic monitoring. Stress echocardiography can also evaluate functional abnormalities instead of relative perfusion defects. Overall, stress echocardiography is currently an underutilized imaging modality that has a wide, and expanding, range of application in the practice of pediatric and congenital cardiology.

Risk factor profiling and study of atherosclerotic coronary plaque burden and morphology with coronary computed tomography angiography in coronary artery disease among young Indians

BackgroundWith a decade earlier manifestation of coronary artery disease (CAD) and paucity of data characterizing coronary plaque with coronary computed tomography angiography (CTA) among CAD patients in India, the study aimed to analyze patient characteristics and coronary plaque burden and morphology in young Indian patients with CAD. MethodsSerial coronary CTA was performed in 96 CAD patients. Among 60 patients ≤40years, risk factor and coronary plaque analysis done using a 256- slice CT in 33 patients with acute coronary syndrome (ACS) was compared with 27 patients with chronic stable angina (CSA). Univariate and multivariate analysis was performed, for factors predicting ACS as an outcome among young CAD patients. In addition, quantitative and morphologic plaque characteristics were compared among those ≤40years and >40years. ResultsAmong 60 subjects ≤40years of age, 77% had dyslipidemia, 70% high lipoprotein(a), 53.33% elevated hs-CRP and 73.33% raised homocysteine. hs-CRP (9.33 vs. 3.33, p value=0.01) and serum triglycerides (178.67 vs. 141.42, p value=0.03) were markedly raised in patients with ACS. Statistically significant number of patients in the ACS group had positive remodelling (ACS, 69.7% vs. CSA, 14.8%; p value<0.001), low attenuation plaque (ACS, 63.6% vs. CSA, 11.1%; p value<0.001), spotty calcification (ACS, 36.4% vs. CSA, 3.7%; p=0.002) and non-calcified plaque (ACS, 69.7% vs. CSA, 11.1%; p<0.001). On multivariate analysis, only lipoprotein (a) >30mg/dL and composite vulnerability score maintained a predictive value for ACS in patients ≤40years. Statistically significant number of patients in the younger age group had higher mean total plaque volume (66.17±41.31mm3 vs. 44.94±49.07mm3; p=0.03), remodelling index (1.5±0.27 vs. 1.08±0.38; p=0.0001). Comparing culprit lesion characteristics of ACS patients in the two age groups, positive remodelling (95.8% vs. 70.5%, p=0.02), spotty calcification (50% vs. 11.7%, p=0.01) and non-calcified plaque (95.8% vs. 70.5%, p=0.02) were significantly more frequent in patients ≤40years. ConclusionACS in young Indians is characterized by a higher prevalence of both conventional and newer risk factors. In addition, culprit lesions in young ACS patients are more frequently characterized by coronary plaques with high risk morphological features. This may have implications in terms of preventive strategies to identify this high-risk group.

Presence, Characteristics, and Volumes of Coronary Plaque Determined by Computed Tomography Angiography in Young Type 2 Diabetes Mellitus

Prevention and management of coronary artery disease (CAD) is of great concern in patients with diabetes mellitus. Although the impact of coronary atherosclerosis is described well for subjects older than 40years, the prevalence and types of coronary atherosclerosis in young patients are not well known. The aim of this study was to evaluate the prevalence, extent, severity, and volumes of coronary plaque in type 2 diabetes mellitus (T2DM) population younger than of 40years. This prospective study enrolled 181 subjects (25-40year old) undergoing coronary computed tomography angiography, with 86 T2DM and 95 nondiabetic age/gender-matched subjects. Coronary artery calcium (CAC), plaque assessment including total segment stenosis (sum of individual segmental stenosis), total plaque scores (sum of semiquantitative segmental plaque burden), segment involvement scores (number of segments with plaque) were evaluated. In addition, we quantitatively measured plaque volumes in total, fibrous, fibrous fatty, dense calcified, and low-attenuation plaque using novel plaque software. Compared with nondiabetic patients, the prevalence of CAD, calcified, and noncalcified plaques was higher in patients with T2DM (19% vs 58%; p <0.001). In patients with a zero CAC, T2DM had a higher prevalence (46%) of noncalcified plaque (p <0.0001). In multivariate linear regression models after adjusting for traditional cardiovascular risk factors, increased total segmental stenosis, total plaque scores, and segment involvement scores were associated with T2DM. Regarding quantitative plaque assessment, all volumes in noncalcified plaque type were approximately threefold higher in patients with T2DM. In conclusion, young patients with T2DM are susceptible to premature CAD with more calcified and noncalcified plaques. Early prevention program using computed tomography angiography might be helpful in identifying young diabetic patients with subclinical atherosclerosis.

Association of serum gamma-glutamyltransferase and premature coronary artery disease.

BackgroundSerum gamma-glutamyltransferase (GGT) has been introduced as a predictive factor for cardiovascular disease. In this study, we investigated the association of serum GGT and premature coronary artery disease (CAD) in candidates for coronary angiography.MethodsIn this cross-sectional study, we enrolled male subjects aged ≤45 years and female subjects ≤55 years who were candidates for elective coronary angiography due to typical chest pain or a positive non-invasive test. Baseline characteristics were recorded for all the participants and serum levels of blood glucose, lipid profile and GGT were measured. Patients were divided into CAD and non-CAD groups based on angiography for further comparisons.ResultsFrom a total of 367 patients (age 45.1 ± 6.1 years, 161 males [43.9%]), 176 (47.9%) patients had premature CAD. A high level of GGT was significantly associated with the presence of CAD (p < 0.001). A 10-unit increase in GGT could strongly predict the presence of premature coronary artery disease (OR: 13.34, 95% CI: 7.19–24.78; p < 0.001) after adjustment for confounders. The area under the receiver operating characteristic curve for GGT was 80.9% (range 76.5–85.3) and the sensitivity and specificity of GGT at a cut-point of 22.5 IU/l was 80.1% and 70.2%, respectively. Diagnostic accuracy of GGT was 74.9%. The positive predictive value and negative predictive value for GGT was 71.3 and 79.3, respectively.ConclusionWe observed that GGT levels in patients with typical chest pain or positive non-invasive tests could predict the presence of premature CAD in young patients.

Free triiodothyronine in relation to coronary severity at different ages: Gensini score assessment in 4206 euthyroid patients.

ObjectiveTo study whether free triiodothyronine (FT3) within normal range has effects on the presence and severity of coronary artery disease (CAD) in different gender and age groups.MethodsA total of 4206 euthyroid patients were consecutively enrolled and divided into CAD group (n = 3306) and non-CAD group (n = 900). All patients underwent coronary angiography (CAG). Gensini score (GS) was used to determine the severity of coronary artery stenosis. Severe CAD was defined as GS > 32 and mild CAD was defined as GS ≤ 32. Logistic regression analysis and linear regression analysis were conducted to determine the association of FT3 with CAD in patients with different gender and ages.ResultsConcentration of FT3 was lower in patients with CAD than that in angiography-normal control group (P < 0.05). In addition, concentration of FT3 was lower in severe CAD than that in mild CAD. After adjusting for traditional cardiovascular risk factors and potential confounders, FT3 was negatively correlated with the presence of CAD, but not in the old patients (> 65 years old). Multivariable linear regression analysis showed that FT3 was negatively associated with GS in male and young patients with stable CAD, but not in the old patients.ConclusionsLow FT3 within normal range was negatively associated with the presence and severity of CAD in young patients, but not in the old ones. Further studies are needed to confirm our findings.

ANRIL rs2383207 polymorphism and coronary artery disease (CAD) risk: a meta-analysis with observational studies.

Some studies investigated the association of antisense non-coding RNA in the INK4 locus (ANRIL) rs2383207 polymorphism with coronary artery disease (CAD) risk. However, the result was still inconsistent. The aim of this study was to investigate whether there is an association between the ANRIL rs2383207 polymorphism and CAD risk. We carried out a PubMed (Medline), EMBASE database search covering all published articles. The strength of association between ANRIL rs2383207 polymorphism and CAD risk was assessed by calculating OR with 95% CI. A total of 13 case-control studies involving 6796 cases and 9956 controls were included in this meta-analysis. ANRIL rs2383207polymorphism was associated with a significantly an increased risk of CAD (OR=1.47; 95%CI, 1.33-1.62). We also found that this polymorphism increased CAD risk in Caucasians (OR=1.51; 95%CI, 1.28-1.77) and Asians (OR=1.42; 95%CI, 1.26-1.61). In the subgroup analysis according to gender, both women and men were significantly associated with the increased risk of CAD (OR=1.36; 95%CI, 1.03-1.79 and OR=1.58; 95%CI, 1.20-2.09). In the subgroup analysis by age, ANRIL rs2383207 polymorphism showed significant results in old CAD patients and young CAD patients (OR=1.32; 95%CI, 1.20-1.44 and OR=1.53; 95%CI, 1.32-1.77). Furthermore, this polymorphism also influenced myocardial infarction risk (OR=1.75; 95%CI, 1.24-2.47). Even the studies with adjustment for age, gender, smoking were included, the significant association was also observed (OR=1.43; 95%CI, 1.26-1.62). In conclusion, this meta-analysis suggested that ANRIL rs2383207 polymorphism is associated with CAD risk.

Coronary Artery Disease in Young Adults: Who Needs Surgical Revascularization? A Retrospective Cohort Study.

Coronary artery disease (CAD) is a major cause of death and disability in developed countries. Despite the fact that prevalence accrues with age, an increasing number of young patients suffering from CAD is being observed worldwide. The aim of this study is to describe the population of young adults suffering from CAD and requiring coronary artery bypass grafting (CABG), and to assess early outcomes after the procedure. A retrospective cohort study analyzed 190 consecutive patients aged ≤50 years old that underwent CABG between 2010 and 2014. Baseline characteristics and operative data were presented in the study. Postoperative complications, such as major adverse cardiac and cardiovascular events (MACCE), prolonged mechanical ventilation (&gt;72 hours), bleeding requiring reexploration, sternal dehiscence, and others were assessed. A population comprising mostly overweight or obese males with a mean age of 46 ± 4.1 years was analyzed. Patients suffered mostly from three-vessel disease (81%), hypertension (74.7%), and had previous history of myocardial infarction (MI) (60%). The majority of patients had normal left ventricle ejection fraction (LVEF) (83.1%). 22.6% of cases were emergent procedures. Perioperative mortality was low (1%) and overall MACCE rate stood at 2.6%. Emergent surgery was associated with a higher incidence of postoperative complications (P = .007). The number of diseased vessels, LVEF, and CCS/NYHA class-on-admission was not associated with a higher incidence of postoperative complications (P &gt; .05 for all). CAD in young patients remains an issue described insufficiently in the literature. Among our study cohort of younger patients undergoing CABG, the majority of the patients had multivessel disease and were slightly symptomatic with normal LVEF. Although the postoperative complication rate was low, the percentage of emergent surgeries was alarmingly high in this population. Consistent with the literature, we highlight the importance of CAD screening in the young population to detect subclinical disease, which might be treated therapeutically or operated electively.
