Association of premature atherosclerotic cardiovascular disease with higher risk of cancer: a behavioral risk factor surveillance system study.

AIM: The aim of this study was to investigate a possible association between atherosclerotic cardiovascular disease (ASCVD) and risk of cancer in young adults. METHODS: We utilized data from the Behavioral Risk Factor Surveillance System, a nationally representative US telephone-based survey to identify participants in the age group of 18-55 years who reported a history of ASCVD. These patients were defined as having premature ASCVD. Weighted multivariable logistic regression models were used to study the association between premature ASCVD and cancer including various cancer subtypes. RESULTS: Between 2016 and 2019, we identified 28 522 (3.3%) participants with a history of premature ASCVD. Compared with patients without premature ASCVD, individuals with premature ASCVD were more likely to be Black adults, have lower income, lower levels of education, reside in states without Medicaid expansion, have hypertension, diabetes mellitus, chronic kidney disease, obesity, and had delays in seeking medical care. Individuals with premature ASCVD were more likely to have been diagnosed with any form of cancer (13.7% vs 3.9%), and this association remained consistent in multivariable models (odds ratio, 95% confidence interval: 2.08 [1.72-2.50], P < 0.01); this association was significant for head and neck (21.08[4.86-91.43], P < 0.01), genitourinary (18.64 [3.69-94.24], P < 0.01), and breast cancer (3.96 [1.51-10.35], P < 0.01). Furthermore, this association was consistent when results were stratified based on gender and race, and in sensitivity analysis using propensity score matching. CONCLUSION: Premature ASCVD is associated with a higher risk of cancer. These data have important implications for the design of strategies to prevent ASCVD and cancer in young adults.

Hospital Readmission in Patients With Spontaneous Coronary Artery Dissection.

Spontaneous coronary artery dissection (SCAD) can present with various clinical symptoms, including chest pain, syncope, and sudden cardiac death, particularly in those without atherosclerotic risk factors. In this contemporary analysis, we aimed to identify the causes and predictors of 30-day hospital readmission in SCAD patients. We utilized the latest Nationwide Readmissions Database from 2016 - 2017 to identify patients with a primary discharge diagnosis of SCAD. The primary outcome was 30-day readmission. Among 795 patients admitted with a principal discharge diagnosis of SCAD, 85 (11.3%) were readmitted within 30 days of discharge from index admission (69.8% women, mean age of 54.3 ± 0.8). More than half of the readmissions (57%) were cardiac-related readmissions. Common cardiac causes for 30-day hospital readmission were acute coronary syndrome (27.3%), chest pain/unspecified angina (24.6%), heart failure (17.5%), and recurrent SCAD (8.3%). In conclusion, we found that following hospitalization for SCAD, almost one-tenth of patients were readmitted within 30 days, largely due to cardiac cause . Risk stratifying patients with SCAD, identifying high-risk features or atypical phenotypes of SCAD, and using appropriate management strategies may prevent hospital readmissions and reduce healthcare-related costs. Further studies are warranted to confirm these causes of readmission in SCAD patients.

Premature Atherosclerotic Cardiovascular Disease Risk Among Patients with Inflammatory Bowel Disease.

BACKGROUND: Recent literature has shown an association between atherosclerotic cardiovascular disease and inflammatory bowel disease, potentially mediated through chronic inflammatory pathways. However, there is a paucity of data demonstrating this relationship among young patients with premature atherosclerotic cardiovascular disease. METHODS: Using data from the nationwide Veterans wIth premaTure AtheroscLerosis (VITAL) registry, we assessed the association between extremely premature and premature atherosclerotic cardiovascular disease (age at diagnosis: ≤40 years and ≤55 years, respectively) and inflammatory bowel disease. Patients were compared with age-matched controls without atherosclerotic cardiovascular disease. Multivariable regression models adjusted for traditional risk factors. RESULTS: We identified 147,600 patients and 9485 patients with premature and extremely premature atherosclerotic cardiovascular disease, respectively. Compared with controls, there was a higher prevalence of overall inflammatory bowel disease among premature (0.96% vs 0.84%; odds ratio [OR] 1.14; 95% confidence interval [CI], 1.08-1.21) and extremely premature (1.36% vs 0.75%; OR 1.82; 95% CI, 1.52-2.17) patients. After adjustment, these associations attenuated in both premature and extremely premature groups (OR 1.07; 95% CI, 1.00-1.14 and OR 1.61; 95% CI, 1.34-1.94, respectively). CONCLUSION: Inflammatory bowel disease is associated with higher odds of extremely premature atherosclerotic cardiovascular disease, especially for those age ≤40 years. With increasing age, this risk is attenuated by traditional cardiometabolic factors such as obesity, hypertension, diabetes, smoking, and dyslipidemia. Prospective studies are needed to assess the role of early intervention to decrease cardiovascular risk among young patients with inflammatory bowel disease.

Recreational substance use among patients with premature atherosclerotic cardiovascular disease.

OBJECTIVE: Despite an upsurge in the incidence of atherosclerotic cardiovascular diseases (ASCVD) among young adults, the attributable risk of recreational substance use among young patients has been incompletely evaluated. We evaluated the association of all recreational substances with premature and extremely premature ASCVD. METHODS: In a cross-sectional analysis using the 2014-2015 nationwide Veterans Affairs Healthcare database and the Veterans wIth premaTure AtheroscLerosis (VITAL) registry, patients were categorised as having premature, extremely premature or non-premature ASCVD. Premature ASCVD was defined as having first ASCVD event at age <55 years for men and <65 years for women. Extremely premature was defined as having first ASCVD event at age <40 years while non-premature ASCVD was defined as having first ASCVD event at age ≥55 years for men and ≥65 years for women. Patients with premature ASCVD (n=135 703) and those with extremely premature ASCVD (n=7716) were compared against patients with non-premature ASCVD (n=1 112 455). Multivariable logistic regression models were used to study the independent association of all recreational substances with premature and extremely premature ASCVD. RESULTS: Compared with patients with non-premature ASCVD, patients with premature ASCVD had a higher use of tobacco (62.9% vs 40.6%), alcohol (31.8% vs 14.8%), cocaine (12.9% vs 2.5%), amphetamine (2.9% vs 0.5%) and cannabis (12.5% vs 2.7%) (p<0.01 for all comparisons). In adjusted models, the use of tobacco (OR 1.97, 95% CI 1.94 to 2.00), alcohol (OR 1.50, 95% CI 1.47 to 1.52), cocaine (OR 2.44, 95% CI 2.38 to 2.50), amphetamine (OR 2.74, 95% CI 2.62 to 2.87), cannabis (OR 2.65, 95% CI 2.59 to 2.71) and other drugs (OR 2.53, 95% CI 2.47 to 2.59) was independently associated with premature ASCVD. Patients with polysubstance use had a graded response with the highest risk (~9-fold) of premature ASCVD among patients with use of ≥4 recreational substances. Similar trends were observed among patients with extremely premature ASCVD. Gender interactions with substance use were significant (p-interaction <0.05), with recreational substance use and premature ASCVD showing stronger associations among women than in men with premature ASCVD. CONCLUSIONS: All subgroups of recreational substances were independently associated with a higher likelihood of premature and extremely premature ASCVD. Recreational substance use confers a greater magnitude of risk for premature ASCVD among women. A graded response relationship exists between increasing number of recreational substances used and higher likelihood of early-onset ASCVD.

Highlights from Studies Presented at the American Heart Association Scientific Session 2020: Navigating New Roads in Prevention.

PURPOSE OF THE REVIEW: This review highlights late-breaking science presented at the American Heart Association Scientific Session 2020 that demonstrated advancements in preventative cardiology and introduced novel treatment approaches for the management of chronic kidney disease, type 2 diabetes, and/or heart failure. RECENT FINDINGS: The studies reviewed include clinical trials that assessed the use of omecamtiv in the treatment of heart failure with reduced heart failure (GALACTIC-HF); effects of sotagliflozin in patients with diabetes and recent heart failure exacerbation; cardiovascular outcomes with the use of omega-3 carboxylic acids in patients with high vascular risk and atherogenic dyslipidemia (STRENGTH) and omega-3 fatty acids in elderly patients with recent myocardial infarction (OMEMI); efficacy and safety of evinacumab in patients with refractory hypercholesterolemia; and the use of coronary computed tomography angiography for the assessment of suspected acute coronary syndrome. In addition, we review the results of the International Polycaps Study (TIPS-3) on the use of a polypill for the primary prevention of cardiovascular disease in intermediate-risk people. Finally, we discuss the SAMSON trial-a three-arm-N-of-1 trial-to identify the root cause of the symptoms contributing to patient nonadherence to statin therapy. The studies presented at the American Heart Association Scientific Session 2020 represent remarkable contributions in the field of cardiovascular disease and prevention.

Eligibility for Low-Dose Rivaroxaban Based on the COMPASS Trial: Insights from the Veterans Affairs Healthcare System.

INTRODUCTION: Low-dose rivaroxaban reduced major adverse cardiac and limb events among patients with stable atherosclerotic vascular disease (ASCVD) in the COMPASS trial. The objective of our study was to evaluate the eligibility and budgetary impact of the COMPASS trial in a real-world population. METHODS: The VA administrative and clinical databases were utilized to conduct a cross-sectional study to identify patients eligible for low-dose rivaroxaban receiving care at all 141 facilities between October 1, 2014 and September 30, 2015. Proportion of patients with stable ASCVD eligible for low-dose rivaroxaban and prevalence of multiple risk enrichment criteria among eligible patients. Pharmaceutical budgetary impact using VA pharmacy pricing. Chi-squared and Student's t tests were used to compare patients eligible versus ineligible patients. RESULTS: From an initial cohort of 1,248,214 patients with ASCVD, 488,495 patients (39.1%) met trial eligibility criteria. Eligible patients were older (74.2 vs 64.5 years) with higher proportion of hypertension (84.1% vs 82.1%) and diabetes (46.2% vs 32.9) compared with ineligible patients (p < 0.001 for all comparisons). A median of 38.7% (IQR 4.6%) of total ASCVD patients per facility were rivaroxaban eligible. Estimated annual VA pharmacy budgetary impact would range from $0.47 billion to $1.88 billion for 25% to 100% treatment penetration. Annual facility level pharmaceutical budgetary impact would be a median of $12.3 million (IQR $8.0-$16.3 million) for treatment of all eligible patients. Among eligible patients, age greater than 65 years was the most common risk enrichment factor (86.9%). Prevalence of eligible patients with multiple enrichment factors varied from 34.2% (one factor) to 6.2% (four or more). CONCLUSION: Over one third of patients with stable ASCVD may qualify for low-dose rivaroxaban within the VA. Additional studies are needed to understand eligibility in other populations and a formal cost-effectiveness analysis is warranted.

Pathophysiological Mechanisms Underlying Excess Risk for Diabetes and Cardiovascular Disease in South Asians: The Perfect Storm.

BACKGROUND: South Asians are at a significantly increased risk of type 2 diabetes (T2D) and cardiovascular disease (CVD), are diagnosed at relatively younger ages, and exhibit more severe disease phenotypes as compared with other ethnic groups. The pathophysiological mechanisms underlying T2D and CVD risk in South Asians are multifactorial and intricately related. METHODS: A narrative review of the pathophysiology of excess risk of T2D and CVD in South Asians. RESULTS: T2D and CVD have shared risk factors that encompass biological factors (early life influences, impaired glucose metabolism, and adverse body composition) as well as behavioral and environmental risk factors (diet, sedentary behavior, tobacco use, and social determinants of health). Genetics and epigenetics also play a role in explaining the increased risk of T2D and CVD among South Asians. Additionally, South Asians harbor several lipid abnormalities including high concentration of small-dense low-density lipoprotein (LDL) particles, elevated triglycerides, low high-density lipoprotein (HDL)- cholesterol levels, dysfunctional HDL particles, and elevated lipoprotein(a) that predispose them to CVD. CONCLUSION: In this comprehensive review, we have discussed risk factors that provide insights into the pathophysiology of excess risk of T2D and CVD in South Asians.

Non-traditional risk factors and the risk of myocardial infarction in the young in the US population-based cohort.

Although most prevalent in elderly, myocardial infarction (MI) also affects younger adults. We sought to investigate baseline characteristics in young patients (<55 years) with MI using the National Inpatient Sample (NIS) database between 2004 and 2015. Multivariable logistic regression models were used to assess factors associated with acute myocardial infarction (AMI) in young patients. After multivariable analyses adjusted for age, sex, race, family history of atherosclerosis, body mass index (BMI), diabetes, hypertension, hyperlipidemia, chronic kidney disease, and current cigarette smoking; novel risk factors such as human immunodeficiency virus (HIV), systemic lupus erythematosus (SLE), and obstructive sleep apnea (OSA) were associated with a higher risk of developing an AMI in the young (adjusted OR for HIV 4.06; 95 CI 3.48-4.71, p < 0.001), (adjusted OR for SLE 2.12; 95 CI 1.89-2.39, p 0.04), and (adjusted OR for OSA 1.16; 95 CI 1.12-1.20, p < 0.001), respectively. Rheumatoid arthritis was associated with a lower risk of AMI (adjusted OR 0.83; 95 CI 0.76-0.89, p < 0.001). After multivariable analyses, cigarette smoking (adjusted OR 1.98; 95 CI 1.95-2.02, p < 0.001), obesity (adjusted OR 1.37; 95 CI 1.33-1.41, p = 0.003), hyperlipidemia (adjusted OR 1.07; 95 CI 1.04-1.08, p < 0.001) and a family history of CAD (adjusted OR 1.35; 95 CI 1.3-1.4, p < 0.001) were also associated with a higher risk of developing an AMI in the young. In conclusion, young patients with AMI have both traditional risk factors and non-traditional risk factors. In addition to traditional risk factors, close attention should be paid to emerging risk factors such as SLE, HIV and OSA.

Coronary artery disease in the young in the US population-based cohort.

BACKGROUND: Although most prevalent in the elderly, coronary artery disease (CAD) also affects younger adults. However, CAD in young adults is not as well characterized. OBJECTIVE: To explore factors associated with CAD in young patients. METHODS: We investigated the prevalence and baseline characteristics of young patients with CAD using the National Health and Nutrition Examination Survey (NHANES) survey between 1999 and 2016. The primary outcome was a reported history of CAD at age <55 years old, defined based on the subject's response to survey questions 'Have you ever been told by a physician that you had coronary artery disease?' and 'How old were you when were told you had coronary heart disease?'. Multivariable logistic regression models were used to assess factors associated with CAD in young patients. RESULTS: Of 42,038 NHANES participants, 707 (1.7%) reported CAD at young age. Young patients with CAD were more likely to be male, non-whites, cigarette smokers, recreational drug users, had a family history of CAD, compared to young patients without CAD (all p-values <0.05). In multivariable logistic regression models, diabetes (OR: 3.94; 95% CI: 1.32-11.8; P=0.01), cigarette smoking (OR: 2.86; 95% CI: 1.52-5.53; P=0.001), alcohol consumption (OR: 1.17; 95% CI: 1.04-1.35; P=0.01) and cocaine use (OR: 4.48; 95% CI: 1.33-15.1; P=0.01) were independently associated with CAD in young patients. CONCLUSION: CAD in young patients may be influenced by lifestyle factors such as alcohol consumption or cocaine use, as well as conventional risk factors such as smoking or diabetes.

Premature Atherosclerotic Cardiovascular Disease: What Have We Learned Recently?

PURPOSE OF REVIEW: In contrast to patients with non-premature atherosclerotic cardiovascular disease (ASCVD), patients with premature ASCVD have not observed a similar decline in cardiovascular mortality and recurrent adverse events. We sought to review the underlying risk factors, potential gaps in medical management, associated outcomes, and tools for risk prognostication among patients with premature ASCVD. RECENT FINDINGS: In addition to traditional cardiovascular risk factors (i.e., diabetes, familial hypercholesterolemia), non-traditional risk factors such as chronic inflammatory conditions, recreational drug use, genetics, and pregnancy-related complications play a key role in development and progression of premature ASCVD. Patients with premature ASCVD, and especially women, receive less optimal medical management as compared to their non-premature counterparts. There is an increasing prevalence of cardiovascular risk factors among young adults. Hence, this population remains at an elevated risk for premature ASCVD and subsequent adverse cardiovascular events. Future studies evaluating different risk assessment tools and focusing on young patients across all three major domains of ASCVD are needed.

Cardiovascular Disease Prevention in Focus: Highlights from the 2019 American Heart Association Scientific Sessions.

PURPOSE OF THE REVIEW: This review highlights selected cardiovascular disease (CVD) prevention studies presented at the 2019 American Heart Association (AHA) Scientific Sessions. RECENT FINDINGS: Several important cardiovascular prevention studies were presented at the 2019 AHA Scientific Sessions. Results from the Colchicine Cardiovascular Outcomes Trial (COLCOT) showed that low-dose colchicine reduces the risk of recurrent CVD events among patients with recent myocardial infarction. A prospective analysis from the UK Biobank cohort demonstrated that the increased CVD risk associated with clonal hematopoiesis of indeterminate potential is mitigated by a common disruptive mutation in the IL6R gene that suppresses the pro-inflammatory IL-1ß/IL-6 pathway. The Treat Stroke to Target trial demonstrated that reducing low-density lipoprotein cholesterol to <70 mg/dL among patients with ischemic stroke or transient ischemic attack reduces the risk of recurrent CVD events as compared with a higher LDL-C target of 90-110 mg/dL. A secondary analysis focusing on American participants enrolled in the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT) showed that these patients receive a similar benefit in terms of cardiovascular risk reduction with icosapent ethyl as compared with the entire trial population. A post hoc analysis of the Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk (FOURIER) trial demonstrated that a genetic risk score comprising 27 single-nucleotide polymorphisms is associated with cardiovascular risk among patients with established atherosclerotic CVD and patients with high genetic risk receive a relatively higher benefit from evolocumab use. Similar results were observed with alirocumab use in a post hoc analysis of the ODYSSEY OUTCOMES trial where a genome-wide polygenic risk score comprising 6.5 million DNA variants was used. These studies presented at 2019 AHA Scientific Sessions will help guide our approach to preventing CVD.

Medical Therapy for Heart Failure Caused by Ischemic Heart Disease.

Patients with heart failure (HF) syndromes have been categorized as those with reduced ejection fraction (EF) or preserved EF (HFpEF), and ischemia plays a key role in both types. HF remains a major cause of morbidity and mortality worldwide, and with the aging of our population this burden continues to rise, predominantly as a result of hospitalizations for HFpEF. Patients with obstructive coronary artery disease more likely have HF with reduced EF, rather than HFpEF, secondary to acute ischemic injury resulting in myocardial infarction, and large outcomes trials of treatments with neurohumoral inhibition have documented reduced adverse outcomes. In contrast, similar treatments in patients with HFpEF have not proven beneficial. This therapeutic dilemma may be attributed, in part, to heterogeneity in the underlying pathophysiology with different systemic and myocardial signaling pathways, despite similar clinical presentations and findings, in patients with HFpEF. Also, emerging evidence indicates that impaired myocardial perfusion and inflammation secondary to multiple comorbidities are key mechanisms in HFpEF. We will thoroughly review the role of ischemic heart disease in the pathogenesis of HF with reduced EF and HFpEF, and discuss the medical management strategies available for these conditions.

Intravascular Ultrasound for Guidance and Optimization of Percutaneous Coronary Intervention.

Percutaneous coronary intervention (PCI) remains the mainstay management of symptomatic obstructive stable coronary artery disease (despite optimal medical treatment) and acute coronary syndrome. Intravascular ultrasound (IVUS) has emerged as an adjunct to angiography, permitting better assessment of the coronary lesion and stent apposition. Data from multiple studies have demonstrated improved clinical and procedural outcomes with IVUS-guided PCI. This review discusses the use of IVUS, with emphasis on technique, parameters, and applications during coronary interventions. In addition, the clinical outcomes data are highlighted with IVUS compared with conventional angiography-guided PCI.
