The Complete Health Improvement Program and Physical Activity

Background: The Complete Health Improvement Program (CHIP) has demonstrated effectiveness in improving multiple cardiovascular disease risk factors. CHIP promotes physical activity, as well as a plant-based whole-food diet. The study objective is to evaluate the effectiveness of CHIP on improving levels of physical activity. Methods: CHIP participants had biomarkers measured at baseline and after the 11th session, consisting of level of physical activity, blood pressure (BP), body mass index (BMI), fasting blood sugar (FBS), and lipid panel. Pre and post data were analyzed using paired t-tests. Results. CHIP demonstrated significant increase in level of physical activity ( P < .001) and decreased BMI, FBS, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides (all P < .001). Increased levels of physical activity correlated with decreased BMI ( P < .001), but not with other biomarkers. Conclusion: CHIP is effective in producing increased level of physical activity and improvement in multiple biomarkers. The increase in physical activity is correlated with decreased BMI.

DNA Methylation Mediates the Association Between Individual and Neighborhood Social Disadvantage and Cardiovascular Risk Factors.

Low socioeconomic status (SES) and living in a disadvantaged neighborhood are associated with poor cardiovascular health. Multiple lines of evidence have linked DNA methylation to both cardiovascular risk factors and social disadvantage indicators. However, limited research has investigated the role of DNA methylation in mediating the associations of individual- and neighborhood-level disadvantage with multiple cardiovascular risk factors in large, multi-ethnic, population-based cohorts. We examined whether disadvantage at the individual level (childhood and adult SES) and neighborhood level (summary neighborhood SES as assessed by Census data and social environment as assessed by perceptions of aesthetic quality, safety, and social cohesion) were associated with 11 cardiovascular risk factors including measures of obesity, diabetes, lipids, and hypertension in 1,154 participants from the Multi-Ethnic Study of Atherosclerosis (MESA). For significant associations, we conducted epigenome-wide mediation analysis to identify methylation sites mediating the relationship between individual/neighborhood disadvantage and cardiovascular risk factors using the JT-Comp method that assesses sparse mediation effects under a composite null hypothesis. In models adjusting for age, sex, race/ethnicity, smoking, medication use, and genetic principal components of ancestry, epigenetic mediation was detected for the associations of adult SES with body mass index (BMI), insulin, and high-density lipoprotein cholesterol (HDL-C), as well as for the association between neighborhood socioeconomic disadvantage and HDL-C at FDR q < 0.05. The 410 CpG mediators identified for the SES-BMI association were enriched for CpGs associated with gene expression (expression quantitative trait methylation loci, or eQTMs), and corresponding genes were enriched in antigen processing and presentation pathways. For cardiovascular risk factors other than BMI, most of the epigenetic mediators lost significance after controlling for BMI. However, 43 methylation sites showed evidence of mediating the neighborhood socioeconomic disadvantage and HDL-C association after BMI adjustment. The identified mediators were enriched for eQTMs, and corresponding genes were enriched in inflammatory and apoptotic pathways. Our findings support the hypothesis that DNA methylation acts as a mediator between individual- and neighborhood-level disadvantage and cardiovascular risk factors, and shed light on the potential underlying epigenetic pathways. Future studies are needed to fully elucidate the biological mechanisms that link social disadvantage to poor cardiovascular health.

P428 PRESCRIPTION APPROPRIATENESS AND EFFECTIVE CLINICAL IMPACT OF EXERCISE STRESS TEST IN ROUTINE DAILY PRACTICE

Abstract Rationale In the clinical setting, and particularly in the cardiovascular field, an exponential increase of non–invasive diagnostic tests has been observed. Between these, the exercise stress test represents a low–sensitivity and low–specificity diagnostic approach and its use has been less and less recommended in national and international guidelines. However, in the Italian clinical common practice it continues to be extensively prescribed both for chronic coronary syndrome (CCS) follow–up and for screening of coronary artery disease (CAD) in asymptomatic patients with multiple cardiovascular risk factors. Materials and Methods A retrospective cohort single–center study was conducted and 968 consecutives patients undergoing ECG stress test at our Department between October 2018 and March 2019 were included. Appropriateness of prescription and impact on the following diagnostic and therapeutic pathway has been analyzed. Results In this series, the main indication for exercise stress test was subclinical ischemia detection in CCS follow–up (312 pts, 32.3%). 181 tests (18.2%) were undertaken for CAD detection in patients symptomatic for chest pain and 171 (17.7%) for CAD detection in asymptomatic patients with multiple cardiovascular risk factors. At last, 97 tests (10%) were prescribed for arrhythmic burden evaluation and exercise response in patients with documented hyperkinetic arrhythmias. 590 tests (61%) were considered significative for reaching heart rate significance threshold (85% of target heart rate); between these 53 (9%) were positives for symptoms or ECG modifications. Among the positive tests, 25 patients (2.6%) went to the catheterization laboratory for coronary angiography: the indications for the exercise stress testing were chest pain for 14 of these patients while 7 undertook the examination for CCS follow–up. No asymptomatic patient presented for CAD screening undertook coronary angiography. At the end of the diagnostic pathway, 9 patients (0.9% of the complete cohort) received percutaneous or surgical revascularization. Conclusions Routinary and extensive use of exercise stress test can lead to dispersion of resources with many inappropriate examinations. Accurate clinical evaluation and appropriate prescription, especially regarding chest pain evaluation, are the foundations for a significative impact on clinical history of patients.

P234 A RARE CASE OF ACUTE RIGHT HEART FAILURE PRESENTED IN A CASE REPORT

Abstract Case Summary A 62–year–old male with multiple cardiovascular risk factors, presented at the ED with signs and symptoms of right heart failure, Doppler echocardiography showed a severe dilatation and dysfunction of the right ventricle and left ventricular diastolic dysfunction. After initial stabilization with diuretics and inotropes, the patient performed a coronary angiogram with evidence of severe multivessel coronary artery disease and combined pre–capillary and post–capillary pulmonary hypertension as shown by the right heart catheterization. After complete revascularization, the diastolic function of the left ventricle improved dramatically, and the right ventricle recovered completely. Discussion We presented a paradigmatical case of acute right heart failure secondary to left ventricular diastolic impairment in a patient affected by severe ischemic coronary artery disease. Several risk factors are associated with RVD in HFpEF: atrial fibrillation, male sex, chronic obstructive pulmonary disease. Diastolic performance of the LV is one of the main determinants of the right ventricular function, which, in turn, is proven to have prognostic implication in HFpEF. Nowadays, there is no evidence–based treatment for right heart failure secondary to decompensated HFpEF and therapy should be tailored to the individual patient’s response.

Fitness and arterial stiffness in healthy aging: Modifiable cardiovascular risk factors contribute to altered default mode network patterns during executive function

Increases in cardiovascular risks such as high blood pressure and low physical fitness have been independently associated with altered default mode network (DMN) activation patterns in healthy aging. However, cardiovascular risk is a multidimensional health problem. Therefore, we need to investigate multiple cardiovascular risk factors and their contributions to cognition and DMN activations in older adults, which has not yet been done. The current fMRI study examined contributions of two common modifiable cardiovascular risk factors (arterial stiffness and physical fitness) on DMN activations involved during random n-back, a task of executive functioning and working memory, in older adults. The results show that high cardiovascular risk of either increased arterial stiffness or decreased fitness independently contributed to worse task performance and reduced deactivations in two DMN regions: the anterior and posterior cingulate cortices. We then examined not only the potential interaction between the two risk factors, but also their additive (i.e., combined) effect on performance and DMN deactivations. A significant interaction between the two cardiovascular risk factors was observed on performance, with arterial stiffness moderating the relationship between physical fitness and random n-back accuracy. The additive effect of the two factors on task performance was driven by arterial stiffness. Arterial stiffness was also found to be the driving factor when the additive effect of the two risk factors was examined on DMN deactivations. However, in posterior cingulate cortex, a hub region of the DMN, the additive effect on its deactivation was significantly higher than the effect of each risk factor alone. These results suggest that the effects of cardiovascular risks on the aging brain are complicated and multi-dimensional, with arterial stiffness moderating or driving the combined effects on performance and anterior DMN deactivations, but physical fitness contributing additional effect to posterior DMN deactivation during executive functioning.

Association between cardiovascular risk factors and left ventricular strain distribution in patients without previous cardiovascular disease.

BackgroundSome cardiovascular (CV) risk factors, such as hypertension and diabetes mellitus, have been reported to reduce left ventricular (LV) longitudinal strain (LS) even in patients with preserved LV ejection fraction. We hypothesized that multiple CV risk factors might cause changes in myocardial strain. Our study aimed to assess the association between multiple CV risk factors and strain in patients without previous CV disease (CVD).MethodsWe retrospectively evaluated 137 patients without CVD, who underwent echocardiography at our institution between May 2017 and February 2020. They were divided into four groups based on the number of risk factors (group 0: no risk factor, group 1: one risk factor, group 2: two risk factors, and groups 3: three or four risk factors). Risk factors were hypertension, dyslipidemia, diabetes mellitus, and chronic kidney disease. Absolute values of global LS (GLS) and relative apical LS ratio (RALSR) defined using the equation: average apical LS/(average basal LS + average mid LS) and was used as a marker of strain distribution.ResultsOut of 137 patients, group 0 had 35 patients, group 1 had 35 patients, group 2 had 32 patients, and group 3 had 35 patients. GLS was 22.4 ± 2.0%, 21.7 ± 2.1%, 21.3 ± 1.8%, 20.7 ± 2.2%, and RALSR was 0.64 ± 0.06, 0.66 ± 0.06, 0.68 ± 0.08, 0.69 ± 0.07 in groups 0–3, respectively. The one-way ANOVA detected significant differences between groups in GLS (p = 0.005) and RALSR (p = 0.037), respectively. Group 3 had a significantly lower GLS and higher RALSR than group 0 (p < 0.05).ConclusionIn patients without previous CVD, LS decreased especially from the basal segment as the number of cardiovascular risks increased. The segmental LS may be markers of occult LV dysfunction in patients with CV risk factors.

Sex-Specific Causes and Consequences of White Matter Damage in a Middle-Aged Cohort.

ObjectiveTo evaluate potential sex-specific effects of multiple cardiovascular risk factors on white matter pathology in normal aging men and women, as well as potential sex-differences in the association of white matter pathology and cognitive functions.MethodsWe analyzed cross-sectional data of 581 participants (median age: 53 years, 54% women) of the population-based cohort of the BiDirect Study who completed clinical examinations, five neuropsychological tests, and an 3T MRI examination. White matter pathology was determined by the extent of white matter hyperintensities (WMH) on FLAIR images as well as the magnitude of global fractional anisotropy (FA) based on diffusion tensor imaging. Main effects, interaction as well as sex-stratified generalized linear regression models were used to evaluate the moderating effect of sex on the association of hypertension, diabetes mellitus, smoking, and obesity with WMH and FA, respectively. Associations of imaging markers with cognitive test results were determined with linear regression models.ResultsHypertension showed stronger associations with more extensive WMH and less FA in women compared to men. Current smoking was associated with more severe WMH in women only. Adjusted for age and education, WMH were not significantly associated with cognitive tests, but higher FA was associated with better performance in motor function in both sexes and with executive functions in men, even after adjustment for cardiovascular risk factors.ConclusionWe observed a stronger association of hypertension and smoking with white matter damage in women, suggesting a higher susceptibility for vascular pathology in women. However, there was no association of WMH with cognition, and FA was associated with executive function tests only in men, suggesting a higher cognitive reserve in women.

CORRELATION BETWEEN CAROTID INTIMA-MEDIA THICKNESS WITH URINE ALBUMIN CREATININE RATIO IN PATIENTS WITH TYPE 2 DABETES MELLITUS

Introduction: Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of morbidity and mortality for individuals with diabetes. Common conditions coexisting with type 2 diabetes (e.g., hypertension and dyslipidemia) are clear risk factors for ASCVD, and diabetes itself confers independent risk. Large benets are seen when multiple cardiovascular risk factors are addressed simultaneously. Increased urinary albumin excretion (albuminuria) and reduced Glomerular Filtration Rate (GFR) are risk factors for progressive kidney failure and cardiovascular disease. It has been reported that microalbuminuria had a close association with cardiovascular diseases (CVD) as well. It was also reported that microalbuminuria or macroalbuminuria increased the mortality rate by 60 – 80% (1) . Albuminuria can be most easily performed by urinary albumin-to Creatinine ratio (ACR) in a random spot urine collection (2). Atherosclerosis is the main cause of cardiovascular diseases; measurement of IMT (Intima Media Thickness) enables the detection of atherosclerosis lesions of the arterial wall. CIMT (Carotid Intima Media Thickness) can be measured by high frequency B mode ultrasonography, which provides a high degree of accuracy in estimating the arterial wall thickness. B-mode gray scale sonography allows for imaging of atherosclerotic plaques and intima-media thickness of carotid arteries. Of these, continuous- wave Doppler and single-gate pulsed-wave Doppler sonography incorporated in duplex systems are reported to be highly accurate relative to angiography for the detection and classication of the degree of obstruction producing a narrowing of lumen more than 50%. In addition, the use of high-resolution B-mode real-time sonography makes it possible to identify small, non stenotic (&lt;50%) plaques and to describe the echo morphology of carotid arteries (3). The carotid IMT is signicantly higher in diabetic patients than that in non-diabetic patients (4), and the increased IMT can predict future events of silent brain infarction and coronary heart disease in the patients with T2DM (5). Carotid IMT is considered to reect an early stage of macroangiopathy in patients with diabetes. An increasing CIMT above normal level (&gt; 0.8 mm) is associated with increasingly severe coronary artery disease, an increased risk of myocardial infarction and also stroke. Urine ACR is an important marker for the progression of renal dysfunction and is currently recognized as predictive factors for CVD. However, association of IMT with both urinary ACR (Albumin Creatinine Ratio) in type 2 diabetic patients has been investigated in a few reports. Keeping them in mind, a hospital based cross sectional study was performed on the patients presenting with type 2 diabetes mellitus. The study was aimed to establish the role of urine ACR as a leading investigation in patients presenting with type 2 diabetes mellitus for cardiovascular risk assessment. It was intended to evaluate the Carotid IMT in these patients and also detection of atherosclerotic plaque which are clearly related to pathogenesis and aid in planning of management. Our objective is to nd out the correlation between urine ACR and carotid intima media thickness (CIMT) in type 2 diabetes patients and whether urine ACR can be used as a screening tool for risk stratication for future cardiovascular disease in Indian population.

Effect of continuous positive airway pressure treatment on ambulatory blood pressures in high-risk sleep apnea patients: a randomized controlled trial.

The long-term effect of continuous positive airway pressure (CPAP) on 24-hour blood pressure (BP) in patients at high risk with obstructive sleep apnea (OSA) is uncertain. We aimed to determine the effect of CPAP treatment on ambulatory BP in individuals with moderate or severe OSA and cardiovascular disease or multiple cardiovascular disease risk factors without severe sleepiness. In this randomized, controlled, parallel group study, 169 participants were randomly assigned to CPAP treatment or the control group. The primary outcome was the change in mean 24-hour systolic BP between groups from baseline to the average of 6- and 12-month measurements using mixed-effect linear regression models. The 24-hour systolic BP did not significantly differ by group, although there was a trend of decrease in the CPAP group (treatment effect -2.7 mm Hg [95% confidence interval -5.9 to 0.6]; P = .105) compared with control. CPAP had the greatest effect on nighttime systolic BP (treatment effect -5.9 mm Hg [95% confidence interval -9.9 to -1.9]; P = .004). Similar improvements in other nocturnal BP indices were observed. In patients at high risk with moderate-severe OSA without severe sleepiness, CPAP resulted in modest BP improvements over 6 to 12 months of follow-up, with possibly larger effects for nocturnal BP. Use of office blood pressure may underestimate the effect of CPAP on BP profile in patients with OSA.

Role of obesity and blood pressure in epicardial adipose tissue thickness in children.

Elevated body mass index (BMI) has been associated with cardiac changes, such as higher epicardial adipose tissue (EAT) thickness. This fat has been identified as a predictive factor of cardiovascular diseases during adulthood. However, few studies have tested the association of multiple cardiovascular risk factors (high weight or blood pressure) with EAT in adolescents and children. Therefore, the main objective of this current research was to determine the impact of BMI, overweight, obesity, and blood pressure on EAT thickness in children. A descriptive cross-sectional study focused on elementary and high school students aged 6-16 years was carried out by utilizing diverse measurements and instruments, such as echocardiography. EAT thickness (N = 228) was linked to sex (more predominant in boys 2.3 ± 0.6; p = 0.044), obesity (2.3 ± 0.6; p < 0.001), and hypertension (2.6 ± 0.6; p = 0.036). The logistic regression indicated that age, sex, and BMI seemed to be more relevant factors in EAT thickness in children (adjusted R square = 0.22; p < 0.001). This paper examined the associations of sex, age, and cardiovascular risk factors (arthrometric measures and blood pressure) with EAT thickness, indicating that it is necessary to assess whether the findings are associated with future events. Excessive weight gain and blood pressure in the early stages of life have been associated with adipose tissue. This increase in weight and blood pressure has been attributed to alterations in the epicardial adipose tissue linked to anthropometric markers in adults, but no related study has been implemented in Spanish children. This study revealed how higher epicardial adipose tissue is linked to body mass index, other anthropometric parameters, and blood pressure in Spanish children. These measurements are related to high epicardial adipose tissue thickness, which in early stages does not imply pathology but increases the risk of developing cardiovascular diseases.

The New Era of Retinal Imaging in Hypertensive Patients.

Structural and functional alterations in the microcirculation by systemic hypertension can cause significant organ damage at the eye, heart, brain, and kidneys. As the retina is the only tissue in the body that allows direct imaging of small vessels, the relationship of hypertensive retinopathy signs with development of disease states in other organs have been extensively studied; large-scale epidemiological studies using fundus photography and advanced semi-automated analysis software have reported the association of retinopathy signs with hypertensive end-organ damage includes the following: stroke, dementia, and coronary heart disease. Although yielding much useful information, the vessels assessed from fundus photographs remain limited to the larger retinal arterioles and venules, and abnormalities observed may not be that of the earliest changes. Newer imaging modalities such as optical coherence tomography angiography and adaptive optics technology, which allow a greater precision in the structural quantification of retinal vessels, including capillaries, may facilitate the assessment and management of these patients. The advent of deep learning technology has also augmented the utility of fundus photographs to help create diagnostic and risk stratification systems. Particularly, deep learning systems have been shown in several large studies to be able to predict multiple cardiovascular risk factors, major adverse cardiovascular events within 5 years, and presence of coronary artery calcium, from fundus photographs alone. In the future, combining deep learning systems with the imaging precision offered by optical coherence tomography angiography and adaptive optics could pave way for systems that are able to predict adverse clinical outcomes even more accurately.

Contraception for Adolescents and Young Women with Type 2 Diabetes-Specific Considerations.

This article reviews how to address contraception in young women with type 2 diabetes (T2D). The presence of obesity and comorbidities associated with insulin resistance increases the risk of thromboembolic disease and adverse cardiovascular outcomes. Recent studies have shown that adolescents with T2D are at high risk of unintended pregnancy with poor outcomes for the mother and offspring. Adolescents with T2D without severe obesity, micro- or macrovascular disease, or other cardiovascular risk factors can use any contraceptive method. However, only nonhormonal or progestin-only methods may be used when morbid obesity, severe hypertension, micro- or macrovascular disease, or multiple cardiovascular risk factors are present. The medical team must provide preconceptional counseling and contraception to reduce adolescent pregnancies in young women with T2D. Progestin-only or nonhormonal long-acting reversible contraception (LARC) should be recommended for women with T2D with compliance issues or adverse cardiovascular risk profiles.

Cardiovascular Profile of Patients with Type 2 Diabetes in France Based on REWIND CVOT Inclusion Criteria: A Real-World Retrospective Study.

IntroductionThe REWIND study demonstrated a cardiovascular (CV) benefit of dulaglutide treatment in patients with type 2 diabetes (T2D) with or without established cardiovascular disease (CVD). The current study aims to describe similarities and differences between characteristics of patients with T2D in France and the REWIND population.MethodsA retrospective, observational study was conducted in France using primary care IQVIA electronic medical records. Patients aged ≥ 18 years with at least one clinical visit and/or glucose-lowering agent prescription in 2019 were identified. The percentages of patients aged ≥ 50 years with established CVD, aged ≥ 55 years with subclinical CVD or aged ≥ 60 years with multiple CV risk factors based on REWIND definitions were calculated.ResultsA total of 63,927 patients with T2D were included. Mean age was 67 years, 93% were aged ≥ 50 years and 58% were male. The median time since T2D diagnosis was 5.6 years, mean glycated hemoglobin was 7.1% and mean body mass index was 30.4 kg/m2. Of the patients included in the current study, 59.4% fulfilled REWIND CV criteria; 12.4% of patients were ≥ 50 years old with established CVD; 9.7% of patients were aged ≥ 55 years with subclinical vascular disease and 44.7% were aged ≥ 60 years with ≥ 2 CV risk factors.ConclusionAlmost 60% of this primary care French cohort with T2D fulfilled key REWIND CV criteria, with a lower percentage of patients having established CVD than REWIND participants.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13300-021-01200-0.

Retrospective analysis of arterial occlusive events in the PACE trial by an independent adjudication committee

BackgroundThe phase 2 PACE (Ponatinib Ph+ ALL and CML Evaluation) trial of ponatinib showed robust long-term benefit in relapsed Philadelphia chromosome-positive (Ph+) leukemia; arterial occlusive events (AOEs) occurred in ≥ 25% of patients based on investigator reporting. However, AOE rates vary depending on the definitions and reporting approach used.MethodsTo better understand clinically relevant AOEs with ponatinib, an independent cardiovascular adjudication committee reviewed 5-year AOE data from the PACE trial according to a charter-defined process and standardized event definitions.ResultsA total of 449 patients with chronic myeloid leukemia (CML) or Ph+ acute lymphoblastic leukemia (ALL) received ponatinib (median age 59 y; 47% female; 93% ≥ 2 prior tyrosine kinase inhibitors (TKIs); median follow-up, 37.3 months). The adjudicated AOE rate (17%) was lower than the non-adjudicated rate (i.e., rate before adjudication; 25%). The only adjudicated AOE in > 2% of patients was peripheral arterial occlusive disease (4%). Exposure-adjusted incidence of newly occurring adjudicated AOEs decreased over time. Patients with multiple baseline cardiovascular risk factors had higher adjudicated AOE rates than those without risk factors.ConclusionsThis independent adjudication study identified lower AOE rates than previously reported, suggesting earlier overestimation that may inaccurately reflect AOE risk with ponatinib. This trial was registered under ClinicalTrials.gov identifier NCT01207440 on September 23, 2010 (https://clinicaltrials.gov/ct2/show/NCT01207440).

Intervention and in-hospital pharmacoterapies in octogenarian with acute coronary syndrome: a 10-year retrospective analysis of the Malaysian National Cardiovascular Database (NCVD) registry

BackgroundOctogenarians and beyond have often been neglected in the populational study of disease despite being at the highest point of non-modifiable disease risk burden and the fastest-growing age group for the past decade. This study examined the characteristics and in-hospital management of octogenarian patients with acute coronary syndrome (ACS) in a multi-ethnic, middle-income country in South East Asia.MethodThis retrospective study utilised the Malaysian National Cardiovascular Disease- ACS (NCVD-ACS) registry. Consecutive patient data of those ≥80 years old admitted with ACS at 24 participating hospitals from 2008 to 2017 (n = 3162) were identified. Demographics, in-hospital intervention, and evidence-based pharmacotherapies over the 10-years were examined and compared across groups of interests using the Chi-square test. Multivariate logistic regression was used to calculate the adjusted odds ratio of receiving individual therapies according to patients’ characteristics.ResultsOctogenarians made up 3.8% of patients with ACS in the NCVD-ACS registry (mean age = 84, SD ± 3.6) from 2008 until 2017. The largest ethnic group was Chinese (44%). Most octogenarians (95%) have multiple cardiovascular risk factors, with hypertension (82%) being the main. Non-ST-elevation myocardial infarction (NSTEMI) predominated (38%, p < 0.001). Within the 10-year, there were positive increments in cardiovascular intervention and pharmacotherapies. Only 10% of octogenarians with ACS underwent percutaneous coronary intervention (PCI), the majority being STEMI patients (17.5%; p < 0.05). More than 80% were prescribed aspirin (91.3%) either alone or combined, dual antiplatelet therapy (DAPT) (83.3%), anticoagulants (89.7%) and statins (89.6%), while less being prescribed angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (47.6%) and beta-blockers (43.0%). Men were more likely to receive PCI than women (adjusted Odds Ratio (aOR): 0.698; 95% CI: 0.490–0.993). NSTEMI (aOR = 0.402, 95% CI: 0.278–0.583) and unstable angina (UA) (aOR = 0.229, 95% CI: 0.143–0.366) were less likely to receive PCI but more likely given anticoagulants (NSTEMI, aOR = 1.543, 95% CI: 1.111–2.142; UA, aOR = 1.610, 95% CI: 1.120–2.314) than STEMI. The presence of cardiovascular risk factors and comorbidities influences management.ConclusionOctogenarians with ACS in this country were mainly treated with cardiovascular pharmacotherapies. As the number of octogenarians with ACS will continue to increase, the country needs to embrace the increasing use of PCI in this group of patients.

Arterial stiffness in rheumatoid arthritis: Current knowledge and future perspectivess

Rheumatoid arthritis (RA) is characterized by the excess cardiovascular risk that remains essentially unaltered despite current medical advances. The introduction of reliable markers towards early identification and subsequently effective management of high-risk patients with RA are urgently needed. Arterial stiffness represents an early indicator of cardiovascular morbidity and mortality and has emerged as a surrogate marker of cardiovascular disease. From a pathophysiological perspective, it is significantly accelerated by the accumulation of cardiovascular risk factors and is considered an intermediate process towards the development and progression of atherosclerotic cardiovascular disease. The aim of this review is to critically upraise current knowledge on arterial stiffness in patients with RA. Although not all studies concur, increased Pulse Wave Velocity (PWV) has been repeatedly reported in patients with RA. However, results need to be interpreted with caution as most studies enrolled patients with multiple cardiovascular risk factors and/or established cardiovascular disease, or with uncontrolled RA with high levels of systemic inflammation. Whether and to which extent increased arterial stiffness among patients with RA is associated with the disease per se, or rather represents the composite effect of hypertension and other classical cardiovascular risk factors, warrants further investigation. The impact of antirheumatic drugs on arterial stiffness is also discussed. Considering the well-established predictive value of increased PWV both in the general population and patients at high cardiovascular risk, future studies need to focus on the clinical utility of this surrogate risk marker specifically in patients with RA.

Secondary prevention of coronary heart disease in Poland: does sex matter? Results from the POLASPIRE survey.

Adherence to health‑promoting behaviors intended to mitigate modifiable risk factors plays an important role in secondary cardiovascular prevention. We aimed to evaluate sex differences in the prevalence and control of risk factors in patients with coronary heart disease (CHD). The study included 1236 patients who experienced acute coronary syndrome or coronary revascularization within the last 6 to 24 months. Definitions of risk factors and treatment goals were based on the 2016 European Society of Cardiology guidelines on cardiovascular prevention. The prevalence of modifiable risk factors in both sexes was high, and their control inadequate. Women were older (P <0.001) and had a higher accumulation of multiple cardiovascular risk factors than men (P = 0.036). They more frequently had central obesity (P <0.001) and reduced values of glomerular filtration rate (P <0.001). Women more often experienced anxiety (P <0.001), reported lower levels of education (P <0.001) and lower income (P = 0.001), and those in the youngest age group were more likely to be exposed to second‑hand smoking (P = 0.01). A large fraction of the study patients, men and women alike, did not meet the recommended therapeutic goals. For both sexes, participation in cardiac rehabilitation programs was associated with more frequent attainment of the recommended level of physical activity (P = 0.046) and smoking cessation (P = 0.01). The prevalence of cardiovascular risk factors in patients with CHD is high, especially in women. Therapeutic goals are met infrequently in both sexes. This situation calls for widening the access to educational programs and paying greater attention to their proper implementation.

698 Acute coronary syndrome in neoatherosclerosis with major stent malapposition and OCT-guided PCI

AimsDue to its bidimensional nature, angiography is not always sufficient to accurately define coronary lesions, in particular when they are ambiguous or indeterminate. Intracoronary imaging, such as intravascular ultrasound or optical coherence tomography (OCT), is often useful in these cases to better characterize the ambiguous angiographic images, to identify the culprit lesion during acute coronary syndrome (ACS) and to guide percutaneous coronary intervention (PCI).Methods and resultsWe report a case of a 61-year-old male with multiple cardiovascular risk factors and a previous ST-segment elevation myocardial infarction treated by PCI of the right coronary artery (RCA) about 7 years before, wo was admitted to our emergency department after acute onset chest pain. At the time of admission, his ECG was normal and cardiac troponin was below the upper reference limit of normality with positive molecular SARS-CoV-2 diagnostic test. Echocardiogram disclosed a mild left ventricular dysfunction with inferior wall hypokinesia. Coronary angiography showed a moderate in-stent restenosis at mid RCA and a hazy, undetermined image at the proximal edge of the previously implanted stent. Left coronary artery angiography showed only diffuse atherosclerotic disease without significant stenoses and a myocardial bridge at the mid tract of left anterior descending artery. OCT pullback of RCA to better characterize the undetermined lesions shown by angiography. OCT revealed significant neointima hyperplasia and a focal area of neoatherosclerosis with unstable features (fissure/microthrombi) at mid RCA. Severe stent strut malapposition embedded neointimal hyperplasia was observed at the proximal stent edge, resulting in ‘dual’ lumen appearance. The two lesions were treated with a single 3.5/48 mm everolimus-eluting stent (stent-in-stent), which was post-dilated with a 3.5/20 mm non-compliant balloon (18 atm) in the mid-to-distal segments, and 4.5/15 mm (16 atm) and 5.0/8 mm (14 atm) semi-compliant balloons in the proximal stent segment. Post-PCI OCT imaging confirmed good stent expansion and apposition. Our case demonstrates the utility of OCT in clarifying the aetiology of ambiguous angiographic lesions and as a guide for PCI. Indeed, the ‘hazy’ appearance on the angiograms corresponded to the major stent malapposition covered by neointima disclosed by OCT as a ‘dual-lumen’. Of note, OCT allowed to confirm the correct guidewire position in the ‘true’ lumen preventing a crush of the previously implanted stent. OCT was also useful as a diagnostic modality for the identification and characterization of the mechanism underlying the ACS (neoatherosclerosis instability).ConclusionsDue to its unprecedented spatial resolution, OCT enables an ‘optical biopsy’ of the coronary artery wall and intrastent tissue. Therefore, OCT imaging should be considered when lesions are ambiguous or indetermined by coronary angiography to guide the diagnosis and treatments of ACS patients. OCT imaging is also useful to guide stenting and to optimize PCI result, and its impact on clinical outcome is under investigation in large randomized clinical trials.

453 An unexpected finding in an asymptomatic patient planned for non-cardiac surgery

Abstract Aims Left ventricular (LV) aneurysms and pseudoaneurysms are two complications of myocardial infarction, either symptomatic or silent, leading to death or serious morbidity in several cases and often precluding non-cardiac surgery. Here the differential diagnosis is challenging and multimodality imaging is often needed to assess the risk of heart rupture. Methods and results A 71 years-old woman was referred to our Cardiology Department for a preoperative evaluation before lung lobectomy. Her past medical history included multiple cardiovascular risk factors and abdominal aorta aneurysm. She also had severe peripheral arterial disease treated with femoral popliteal bypass surgery in June 2021. In August 2021 she suffered from vascular graft thrombosis requiring a redo surgery. During hospitalization, she was found to have a lung adenocarcinoma. The patient had an unremarkable cardiological history and was asymptomatic. EKG was unremarkable. Transthoracic echocardiography revealed a mildly impaired LV systolic function (EF = 40%), an inferolateral basal wall akinesia and a huge aneurysm with intracavitary thrombus and a wide neck arising right below the posterior mitral annulus. The annular distortion caused by the expanding aneurysm contributed to the development of mitral regurgitation (MR) by displacing the annulus and subvalvular apparatus, resulting in restriction of the posterior mitral valve leaflet, coaptation failure, and moderate MR. Coronary angiography demonstrated a severe 3-vessel coronary artery disease. To further characterize the aneurysm, a cardiac magnetic resonance was carried out. T1 weighted inversion recovery LGE 2-chamber and short axis views showed transmural LGE of the inferior wall and confirmed the presence of a saccular dilatation with thin wall, wide neck (5 × 6 cm) and large intracavitary thrombus at high risk of rupture. Since the presence of metastatic lesions was excluded, the patient underwent cardiac surgery followed by elective lobectomy. Intraoperative findings were consistent with LV aneurysm with a thin myocardial wall. Aneurysm and related thrombus were removed and the orifice was closed with a Dacron patch. In the same setting a myocardial revascularization with two coronary artery bypass grafts was also performed. Surgery was successfully performed without any complication. Intraoperative transesophageal echocardiography clearly revealed the aneurysm and witnessed the reduction of MR after the restoration of LV inferolateral wall geometry. Conclusions Our case highlights the importance of thorough evaluation prior to non-cardiac surgery using multimodality imaging, especially when incidental echocardiographic findings in asymptomatic patients occur. A careful pre-operative assessment of patients planned for non-cardiac surgery is the key to favourable postoperative outcome.
