12217 Exploring Thyroid-stimulating Hormone As A Potential Cardiovascular Disease Risk Marker In Euthyroid Individuals

Abstract Disclosure: A.P. Neto: None. H. Lucchesi: None. C.C. Silva Janovsky: None. I. Bensenor: None. L.S. Ward: None. L.L. Cunha: None. Previous studies have suggested that TSH levels may predict longevity primarily in elderly individuals. Aging is associated with a high prevalence of cardiovascular and metabolic diseases that reduce survival. However, the relationship between serum TSH levels and these conditions, especially traditional cardiovascular risk markers, remains poorly explored. We employed data from the longitudinal multicenter cohort study ELSA-Brasil, which includes workers from five Brazilian Universities, to evaluate thyroid function in 8,452 participants aged between 34 and 75 years, classified as euthyroid and followed for 8.9 ± 0.6 years. The participants were evaluated for the presence of diabetes, hypertension, angina, peripheral arterial disease, and cardiovascular mortality. Additionally, we measured cardiovascular markers, including global cardiovascular risk score, HbA1c, microalbuminuria (mg/dl), LDL levels, and triglyceride levels. Statistical analysis was used to compare TSH levels with clinically relevant outcomes and classical cardiovascular risk markers. We observed that higher TSH levels correlated negatively with global cardiovascular risk (Spearman rank -0.023, p-value=0.038), microalbuminuria (Spearman rank -0.055, p<0.000), and HbA1c (Spearman rank -0.041, p<0.000). However, TSH levels were positively correlated with hypertriglyceridemia (Spearman rank +0.125, p<0.000) but had no relationship with LDL (p >0.05). The appraisal of cardio-metabolic diseases showed that individuals without diabetes had higher TSH levels (1.79 mIU/L, IQR 1.07) than individuals with diabetes (1.71 mIU/L, IQR 1.07). Patients with arteriosclerosis diseases, such as coronary and peripheral arterial disease, had lower TSH levels (1.66, IQR 0.98 and 1.67, IQR 0.94, respectively) than those who did not have these comorbidities (1.79, IQR 1.07, and 1.79, IQR 1.07). Furthermore, TSH levels did not correlate with the incidence of hypertension (p >0.05). Finally, we divided the population into two groups: higher and lower TSH levels based on the median TSH levels (1.78 mIU/L, IQR 1.06). The Kaplan-Meier curve did not show a difference between these groups (p=0.758) in survival after cardiovascular events (08 events in total) during follow-up. In conclusion, our results suggest that higher serum TSH levels in euthyroid individuals are associated with a lower prevalence of metabolic and cardiovascular disease. However, the relatively short observation duration and low frequency of cardiovascular events in our cohort made it difficult to statistically analyze several endpoints, such as survival. Further investigation is necessary to completely understand whether TSH is a cardiovascular risk indicator. Presentation: 6/2/2024

7822 Mild Autonomous Cortisol Secretion In High Suspicious Adrenal Incidentaloma

Abstract Disclosure: N. Zavrashvili: None. N. Margvelashvili: None. K. Chanturishvili: None. Mild Autonomous Cortisol Secretion in High Suspicious Adrenal IncidentalomaIntroduction: Incidentally discovered adrenal masses are common and mostly benign and non-functioning adenomas. However, evolving evidence suggests that a notable proportion of these adrenal adenomas may demonstrate mild autonomous cortisol secretion (MACS), which has been associated with an increased risk for hypertension, hyperglycemia, obesity, dyslipidemia, vertebral fractures, adverse cardiovascular events, and mortality. 55-year-old women with 5-year history of hypertension and hyperlipidemia. She was treated with a three-drug program: verapamil 250 mg daily, combined B-blocker, atenolol 100 mg and chlorthalidone 25 mg daily. Blood pressure control remained suboptimal. Her body mass index was 29,5 kg/m2. She had no signs or symptoms of overt Cushing syndrome.She was referred to CT coronary angiogram by her cardiologist, which revealed adrenal incidentaloma.Adrenal dedicated CT showed left-sided 3,4 cm high density node (41HU), with absolute washout <60. She was consulted by oncologist to exclude adrenal metastasis. The baseline laboratory test results excluded PA and Pheochromocytoma. The diagnosis of glucocorticoid secretory autonomy was based on positive low-dose dexamethasone suppression test (DST), low serum ACTH concentration, low-normal DHEA-S and lack of complete suppression of serum cortisol with an overnight 8-mg DST. Patient was referred to left-sided laparoscopic adrenalectomy with perioperative glucocorticoid coverage (100 mg hydrocortisone administered IV and again 8 hours later). Conclusion: Mild autonomous cortisol secretion is a term used to describe biochemical evidence of abnormal cortisol secretion in patients with adrenal incidentaloma, but without the classical external manifestations of overt CS, such as central muscle weakness, adipose tissue redistribution, and skin fragility. The management of patients with an incidentally discovered adrenal adenoma who do not have overt Cushing’s syndrome but who have MACS is more controversial as the available studies comparing outcomes of adrenalectomy vs conservative management have been generally small. It is associated with an increased risk of Type 2 diabetes mellitus, HBP, obesity, dyslipidemia, and global cardiovascular risk. Therefore, it is of great importance to correctly identify these patients. There are different tests for the screening of hypercortisolism. However, in the absence of a single test considered as the gold standard, it is necessary to combine the different tests to reach an adequate diagnostic capacity. The indication of surgery in ACS patients should be based mainly on the hormonal evaluation and the comorbidities potentially mediated by cortisol. Presentation: 6/1/2024

Blood pressure management strategies and podocyte health.

Hypertension (HTN) is one of the key global cardiovascular risk factors, which is tightly linked to kidney health and disease development. Podocytes, glomerular epithelial cells that play a pivotal role in maintenance of the renal filtration barrier, are significantly affected by increased glomerular capillary pressure in HTN. Damage or loss of these cells causes proteinuria, which marks the initiation of the HTN-driven renal damage. It goes without saying that effective BP management should not only mitigate cardiovascular risks but also preserve renal function by protecting podocyte integrity. This review offers a comprehensive examination of current blood pressure (BP) management strategies and their implications for podocyte structure and function and emphasizes strategies for the reduction of proteinuria in HTN. We explore primary and secondary antihypertensive agents, including ACE inhibitors, ARBs, calcium channel blockers, diuretics, as well as newer therapies (SGLT2 blocking and endothelin receptor antagonism), emphasizing their mechanistic roles in safeguarding podocytes and curtailing proteinuria.

Prognostic algorithm for early diagnosis of subcritical conditions as predictors of sudden cardiac death

Aim. To develop a method for early diagnosis of subcritical homeostasis disorders leading to sudden cardiac death (SCD). The basis is to improve the efficiency of predictive algorithms.Material and methods. This pilot, controlled, open-label, randomized, prospective clinical trial included 220 patients at risk of SCD and 150 patients without risk of SCD. Main and control groups was formed according to the global cardiovascular risk score. Based on the informative features proposed by specialized experts using multivariate statistics methods (discriminant analysis), two condition classes were formed. The conducted exploratory analysis confirmed the significance of diagnostic criteria in relation to SCD manifestation (manifestation of cardiac arrest — MCA), which is an integral assessment of a fatal complication. The development of decision rules was carried out on the basis of soft computing technology.Results. Taking into account the priority of clinical research, namely, the identification of subcritical stages of MCA, a classifier is proposed according to basic severity of patients — the severity of critical condition risk (SCCR). The discriminant function and intersection areas between MCA subclasses in the conditions of early SCD diagnosis determine the transition to soft computing technology. Membership functions for severe MCA are formed, followed by their iteration according to E. Shortliffe. The final decision rule, using a fuzzy classifier, differentiates the MCA into stages with different SCCR. In parallel with standard protocols for the management of severe somatic patients (chronic obstructive pulmonary disease, chronic kidney disease, hepatocellular failure), based on the proposed algorithm with an integral assessment of critical conditions, using the MCA decision rule in the main group in 30,5% of cases, subcritical stage was revealed, followed by targeted treatment and preventive support. In the first group, a subcritical condition was detected in 67 patients (30,5%); a critical condition without SCD — in 3 patients (1,4%). In all noted cases, early prevention of SCD was successfully carried out (these patients were transferred to a class with a lower SCD degree). Using conventional prognostic scores in this group, 46 patients (20,9%) were identified with a subcritical condition and 1 (0,4%) with a critical condition. In the control group, subcritical condition was determined in 35 patients (23,3%), of which 17 patients (11,3%) had a moderate risk of SCD. Using conventional prognostic scores, 23 patients (15,3%) with subcritical condition were identified.Conclusion. In the conditions of intensive care unit, general medicine departments, hemodialysis department, cardiac surgery, and organ transplantation department, an algorithm for early diagnosis and risk stratification of SCD with an integral assessment (MCA) should be used. The fuzzy classifier MCA according to SCCR makes it possible to carry out timely correction of treatment measures in addition to standard protocols.

Lipoprotein(a) as underestimated cardiovascular risk factor in Russia. Time to introduce into clinical practice

An increased concentration of lipoprotein(a) (Lp(a)) is one of the main genetic residual risk factors for atherosclerotic cardiovascular diseases, as well as their complications. Lp(a) is a complex supramolecular complex in which the unique glycosylated apo(a) protein, which has a wide polymorphism, is linked by a disulfide bond to the apoB100 molecule (protein component of the low-density lipoprotein (LDL) particle). Therefore, Lp(a) is often called LDL-like particle. Unlike all other lipoproteins, Lp(a) concentration is determined genetically, almost constant throughout the life, and has wide individual and interethnic variability. As an independent risk factor, elevated Lp(a) concentrations can significantly increase global cardiovascular risk, especially in patients with other risk factors. Modern international and national guidelines recommend measuring Lp(a) concentration not only in certain categories of patients, but also in every person at least once in their life for a correct assessment of cardiovascular risk.

Adherence to optimal medical therapy and control of cardiovascular risk factors in patients after ST elevation myocardial infarction in Mexico.

In developing countries, there is a notable scarcity of real-world data on adherence to optimal medical therapy (OMT) and its correlation with major cardiovascular adverse events (MACEs) after ST-elevation myocardial infarction (STEMI). Our study focuses on addressing this gap by evaluating adherence to OMT, examining its influence on the risk of MACEs after STEMI, and assessing subsequent cardiovascular risk factor control in Mexico. We conducted a prospective observational study of post-STEMI patients after hospital discharge. Adherence to treatment was assessed over a median of 683 days (interquartile range: 478-833) using the Simplified Medication Adherence Questionnaire (SMAQ). Patients were followed up for 4.5 years to monitor MACEs (cardiovascular death, cardiogenic shock, recurrent myocardial infarction, and heart failure). We included 349 patients with a mean age of 58.08 years (±10.9), predominantly male (89.9%). Hypertension (42.4%), smoking (34.3%), type 2 diabetes mellitus (31.2%), obesity (22.92%), and dyslipidemia (21.4%) were highly prevalent. Adherence to OMT per SMAQ was 44.7%. The baseline clinical characteristics of adherent and non-adherent patients did not significantly differ. OMT prescription rates were as follows: acetylsalicylic acid, 91.1%; P2Y12 inhibitors, 76.5%; and high-intensity statins, 86.6%. While non-adherent patients had a numerically higher rate of MACEs (73 vs. 49 first events), there was no statistically significant difference (hazard ratio 1.30, 95% confidence interval 0.90-1.88). In this real-world study of patients after STEMI, we observed low adherence to OMT, a low proportion of global cardiovascular risk factor control, and a numerically higher incidence of recurrent major adverse cardiovascular events in non-adherent patients. Strategies to improve adherence to OMT and risk factor control are needed.

(006) GENITAL VASCULAR RESISTANCE AS A PREDICTOR OF CARDIOVASCULAR RISK ACCORDING TO THE ANALYSIS OF THE PROGETTO CUORE IN PREMENOPAUSAL WOMEN

Abstract Introduction Gender disparity persists in the relationship between sexual dysfunction and cardiovascular risk (CV). It is well- known that erectile dysfunction (ED) represents a sign of subclinical CV pathology and that alterations in color Doppler penile ultrasound parameters serve as predictive markers of major CV events. Female sexual dysfunction (FSD) is a complex condition that involves psychological and organic components, including the cardiovascular system, and affects the quality of life of over a third of women. However, despite its high prevalence, little attention has been paid to the vascular system responsible for blood supply to the female genital apparatus. In men, the hypothesis of penile artery size is a proposed pathophysiological mechanism to address the relationship between the onset of ED symptoms and cardiovascular disease. In recent years, it has also been highlighted that compromised genital vascularization may be a precursor to cardiovascular diseases in women. Objective Our ami gas to investigate the association between clitoral pulsatility index (PI), evaluated through Clitoral color Doppler ultrasound (CDU), and cardiometabolic risk factors in women referred to the Andrology, Women’s Endocrinology and Gender Incongruence Unit, Careggi University Hospital, Florence, Italy. Methods In an observational study, a total of 361 women with a mean age of 45.1 (±13.3) years were evaluated. All patients underwent a thorough medical history assessment, an evaluation of anthropometric parameters, blood sampling for measurement of metabolic and hormonal parameters and a Doppler ultrasound of the clitoral cavernous artery to measure the PI. Results 23.5% of the patients were overweight and 11.6% were obese, 16.3% had hypertension, and 18.6% had metabolic syndrome. In the multivariate analysis, after adjusting for age, the PI was positively correlated with body mass index (BMI) (ß=0.160, p=0.003) and waist circumference (ß=0.186, p=0.002). Furthermore, all women underwent cardiovascular risk assessment, as indicated by Progetto CUORE, assigning a score based on the presence of risk factors (blood pressure, cholesterol levels, smoking, diabetes, age, gender) to estimate the absolute global cardiovascular risk over the next 10 years. We observed that, particularly in women of reproductive age, the clitoral PI was positively correlated with the Progetto CUORE score (r=0.136, p=0.035). Conclusions Clitoral PI increases in relation to several cardiometabolic risk factors. It is therefore relevant to understand how common cardiometabolic alterations may influence vascular function in the female genital tract and whether treating these alterations leads to an improvement in clitoral ultrasound indices, especially in young premenopausal women.

Global Cardiovascular Risk and Associated Factors in 2792 French Military and Civilian Aircrew.

INTRODUCTION: Cardiovascular (CV) diseases are a major public health issue, the prevention of which plays a key role in promoting flight safety. However, few studies have looked at the determinants of the overall risk of CV morbidity-mortality within the various aeronautical occupations.METHODS: A monocentric, observational, cross-sectional study was based on the retrospective data collected during 6 mo at the Toulon Aeromedical Center. From October 2017 to April 2018, 2792 professional aircrew ages 18-74 were included. The overall CV risk was estimated using the European Society of Cardiology SCORE and the Framingham model, as well as a summation model.RESULTS: More than two-thirds of this mainly male population (86.2%) had no more than one CV risk factor [69.9% (68.2-71.6)]. In 82.5% of cases, this was dyslipidemia according to current European criteria [55.8% (52.4-59.1)] or smoking [26.7% (23.8-29.8)]. An overall risk level of "moderate" to "very high" concerned only one subject in five according to the SCORE model [20.1% (18.6-21.6)], one in six according to Framingham [16.3% (14.9-17.7)] and almost one in three according to the summation model [30.1% (28.4-31.9)].DISCUSSION: Multivariate analyses found no significant associations between socio-professional criteria and overall risk levels. The results have underlined the effect of dyslipidemia and smoking on early risk among applicants. Beyond the illustration of favorable cardiovascular status among aircrews related to the standards of selection and close monitoring process, areas for improvement were identified, inviting the development of prevention strategies around the "moderate" overall CV risk.Huiban N, Gehant M, Brocq F-X, Collange F, Mayet A, Monteil M.

WITHDRAWN: Consensus on lipoprotein(a) of the Spanish Society of Arteriosclerosis. Literature review and recommendations for clinical practice

The irruption of lipoprotein(a) (Lp(a)) in the study of cardiovascular risk factors is perhaps, together with the discovery and use of proprotein convertase subtilisin/kexin type 9 (PCSK9i) inhibitor drugs, the greatest novelty in the field for decades. Lp(a) concentration (especially very high levels) has an undeniable association with certain cardiovascular complications, such as atherosclerotic vascular disease (AVD) and aortic stenosis. However, there are several current limitations to both establishing epidemiological associations and specific pharmacological treatment. Firstly, the measurement of Lp(a) is highly dependent on the test used, mainly because of the characteristics of the molecule. Secondly, Lp(a) concentration is more than 80% genetically determined, so that, unlike other cardiovascular risk factors, it cannot be regulated by lifestyle changes. Finally, although there are many promising clinical trials with specific drugs to reduce Lp(a), currently only PCSK9i (limited for use because of its cost) significantly reduces Lp(a).However, and in line with other scientific societies, the SEA considers that, with the aim of increasing knowledge about the contribution of Lp(a) to cardiovascular risk, it is relevant to produce a document containing the current status of the subject, recommendations for the control of global cardiovascular risk in people with elevated Lp(a) and recommendations on the therapeutic approach to patients with elevated Lp(a).

Extrahepatic Vitamin K-Dependent Gla-Proteins-Potential Cardiometabolic Biomarkers.

One mechanism to regulate pathological vascular calcification (VC) is its active inhibition. Loss or inactivation of endogenic inhibitors is a major inductor of VC. Such inhibitors are proteins rich in gamma-glutamyl residues (Gla-proteins), whose function strongly depends on vitamin K. The current narrative review is focused on discussing the role of extrahepatic vitamin K-dependent Gla-proteins (osteocalcin, OC; matrix Gla-protein, MGP; Gla-rich protein, GRP) in cardio-vascular pathology. Gla-proteins possess several functionally active forms whose role in the pathogenesis of VC is still unclear. It is assumed that low circulating non-phosphorylated MGP is an indicator of active calcification and could be a novel biomarker of prevalent VC. High circulating completely inactive MGP is proposed as a novel risk factor for cardio-vascular events, disease progression, mortality, and vitamin K deficiency. The ratio between uncarboxylated (ucOC) and carboxylated (cOC) OC is considered as an indicator of vitamin K status indirectly reflecting arterial calcium. Despite the evidence that OC is an important energy metabolic regulator, its role on global cardio-vascular risk remains unclear. GRP acts as a molecular mediator between inflammation and calcification and may emerge as a novel biomarker playing a key role in these processes. Gla-proteins benefit clinical practice as inhibitors of VC, modifiable by dietary factors.

Association of Periodontitis with Ambulatory Blood Pressure, Salt Intake, and Neutrophil-Lymphocyte Ratio in High-Risk Hypertensive Patients

<i>Objective</i>: Periodontitis and cardiovascular disease are prevalent entities that often coexist, with a common pro-inflammatory pathway. The objective of this study was to evaluate the association between periodontitis and cardiovascular pro-inflammatory parameters rarely considered within risk factors. <i>Methods</i>: Forty-three participants aged between 38-82 years were examined. An association between mean probing depth (MPD), mean attachment loss (MAL), bleeding on probing (BOP), and periodontal inflamed surface area (PISA) was correlated with the following cardiovascular disease factors and inflammatory promoters: neutrophil-to-lymphocyte ratio (NLR), 24h ambulatory blood pressure, global cardiovascular risk, daily salt intake, night-time systolic blood pressure (nSBP), and pulse wave velocity (PWV). A two-way ANOVA and multiple comparison tests were performed using SPSS statistics software. <i>Results</i>: A highly significant correlation (p<0.05) was found between BOP, MPD, and MAL with high salt intake, global cardiovascular risk estimation, nSBP, and PISA. Also, significantly statistical correlation (p<0.05) was found between BOP, NLR, and PWV while PISA was only associated with NLR. Logistic regression analysis identified absolute values of nSBP, salt intake and NLR as possible independent contributors to the increase in the <i>log</i> odds of developing BOP. <i>Conclusions</i>: Several periodontal disease parameters are linked to cardiovascular risk factors such as hypertension, neutrophil-to-lymphocyte ratio, daily salt intake and night-time systolic blood pressure.

Is there a role for earlier use of combination therapy?

As the global population ages and cardiovascular risk factors rise, we can expect a continued increase in atherosclerotic disease. Low-density lipoprotein cholesterol (LDL-C) reduction is a cornerstone of cardiovascular risk reduction with strong, causal evidence indicating that the greatest benefit is derived from early and large decreases in LDL-C. Despite the adoption of statins as the backbone of lipid-therapy regimens, numerous studies and registry analyses reveal our collective inability to achieve LDL-C goals in high-risk patients. Combination therapy with ezetimibe has been shown to result in statistically significant decreases in LDL-C level, atheroma volume, and cardiovascular adverse event rates. A major barrier to implementing an upfront combination therapy approach is the perceived side effects from therapeutic agents although multiple studies show that a therapeutic patient-physician relationship could overcome this issue. Novel agents such as PCSK-9 inhibitors, bempedoic acid, and inclisiran have the potential to achieve similar outcomes although additional research is needed regarding the cost effectiveness of these approaches. Despite these hurdles, there is a role for the newer agents early in the disease course of high-risk patients such as those with markedly elevated LDL-C >190 mg/dL and FH.The implementation of upfront combination therapy, especially in high-risk patients, will decrease clinical inertia while allowing for earlier consideration of newer, effective agents to decrease cardiovascular burden.

Factors associated with usability of the EMPOWER-SUSTAIN Global Cardiovascular Risks Self-Management Booklet© among individuals with metabolic syndrome in primary care: a cross-sectional study

BackgroundSelf-management support has been recognized as one of the most essential elements of the Chronic Care Model (CCM). Inspired by the CCM, the EMPOWER-SUSTAIN Global Cardiovascular Risks Self-Management Booklet© was developed to aid and sustain self-management among patients with metabolic syndrome (MetS) in primary care to prevent cardiovascular complications. However, the usability of this booklet among these patients is not known. Therefore, this study aimed to evaluate the usability of this self-management booklet and identify the factors associated with its usability among patients with MetS in primary care.MethodsThis cross-sectional study was conducted among patients with MetS attending a university primary care clinic in Selangor, Malaysia. The usability score was measured using a previously translated and validated EMPOWER-SUSTAIN Usability Questionnaire (E-SUQ) with a score of > 68 indicating good usability. Multiple logistic regressions determined the factors associated with its usability.ResultsA total of 391 patients participated in this study. More than half (61.4%) had a good usability score of > 68, with a mean (± SD) usability score of 72.8 (± 16.1). Participants with high education levels [secondary education (AOR 2.46, 95% CI 1.04, 5.83) and tertiary education (AOR 2.49, 95% CI 1.04, 5.96)], those who used the booklet at home weekly (AOR 2.94, 95% CI 1.63, 5.33) or daily (AOR 2.73, 95% CI 1.09, 6.85), and those who had social support to use the booklet (AOR 1.64, 95% CI 1.02, 2.64) were significantly associated with good usability of the booklet.ConclusionsThe usability of the EMPOWER-SUSTAIN Global Cardiovascular Risks Self-Management Booklet© was good among patients with MetS in this primary care clinic, which supports its widespread use as a patient empowerment tool. The findings of this study also suggest that it is vital to encourage daily or weekly use of this booklet at home, with the support of family members. The focus should also be given to those with lower education to improve the usability of this booklet for this group of patients.

Circulating culprit or therapeutic bullseye: lipoprotein(a) in cardiovascular risk assessment and novel therapeutic prospects

Lipoprotein(a) [Lp(a)] has emerged as a significant player in the realm of cardiovascular disease (CVD), exerting a pivotal role in atherosclerotic cardiovascular disease (ASCVD), aortic valve stenosis (AVS), and overall cardiovascular (CV) and all-cause mortality. Since its discovery in 1963 by Kåre Berg, our understanding of Lp(a) has undergone significant evolution. This comprehensive review delves into the genetics, structure, assembly, and inter-population differences of Lp(a), shedding light on its intricate involvement in CVD. Genetically, Lp(a) is primarily influenced by variations in the LPA gene. The LPA gene encodes apo(a) and the variation in the kringle domains is the main determinant of plasma Lp(a) levels. Other genetic variants, such as SNPs in the LPA gene region, the pentanucleotide repeat polymorphism, and specific SNPs in the coding sequences of kringle domains, have also been associated with varying Lp(a) concentrations. Additionally, genes outside the LPA locus, including APOE, APOH, and CEPT gene regions, contribute to Lp(a) variability across different populations. Inter-population differences in Lp(a) levels are evident, with ethnicity and sex playing significant roles. Racial disparities in median Lp(a) concentration have been observed, with black individuals often displaying higher levels compared to their white counterparts. The review underscores Lp(a) as an independent, heritable CV risk factor in both primary and secondary settings. High Lp(a) levels are closely linked to the recurrence of myocardial infarction, AVS, and CV events. The necessity of measuring Lp(a) concentration at least once in life to assess an individual's absolute global CV risk is emphasized. Despite substantial progress, many questions remain unanswered about Lp(a), including its physiological role in the cardiovascular system and its involvement in inflammatory and thrombotic processes. Ongoing research holds promise for the development of therapeutic interventions, such as pharmacological agents and apheresis, to mitigate the cardiovascular risks associated with elevated Lp(a) levels. This review highlights the multifaceted nature of Lp(a) in the context of cardiovascular health, emphasizing the importance of continued research efforts to unravel its complexities and develop innovative strategies for managing its associated risks.

Ankle-Brachial Index: Diagnostic Tool of Peripheral Arterial Disease and Predictor of Cardiovascular Risk-An Update of Current Knowledge.

The ankle-brachial index (ABI) was introduced as a screening method for the diagnosis of lower extremity peripheral arterial disease (PAD). Later findings recognized ABI as a prognostic marker of adverse cardiovascular events due to its relation to atherosclerosis in other vascular territories. This narrative review aims to appraise the validity, reliability, and utility of ABI in the detection of PAD and the determination of global atherosclerotic cardiovascular risk. While the ABI value can be influenced by different physiological characteristics including age, sex, body position, and techniques used for ABI determination, it has high specificity and reproducibility in the assessment of vascular patients. In conclusion, when used correctly, the ABI remains a reliable and invaluable indicator of lower-limb perfusion and a useful tool for predicting the risk of future cardiovascular events. However, its underutilization in clinical settings is noteworthy.

Quaternary prevention in the Cardiovascular Health Program Rational use of complementary exams: A narrative review

The Cardiovascular Health Program (PSCV), founded by the Ministry of Health of Chile (Minsal), is focused on the global cardiovascular risk of people with the purpose of preventing and reducing morbidity, disability and premature death caused by cardiovascular diseases, in congruence with its sanitary aims. Quaternary Prevention is defined as "actions taken to protect individuals from medical interventions that are likely to cause more harm than good". The PSVC's 2017 technical guidelines establish a battery of 11 complementary exams to request upon entering the program, however, neither the scientific evidence that supports them nor the periodicity of their request was mentioned. The aim of this revision is to evaluate the rationality of exams request, based on updated evidence, as a strategy for quaternary prevention and potential economic savings for the sanitary system. A narrative review was conducted through searches on databases, updated clinical guidelines and international recommendations about 11 complementary exams on the follow-up of Type 2 Diabetes and Hypertension. Based on the data analysis, recommendations were made according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. It was concluded that the costs of widely requested complementary exams could be reduced through a more efficient management guided by updated evidence. Our proposal entails changes in some processes and in the evaluation of fulfillment of the PSCV, as well as a deeper cost-effectiveness analysis of the recommendations in order to optimize the management of resources in primary health care.

Avaliação do Risco Cardiovascular (SCORE-2) dos Trabalhadores de um Centro Hospitalar entre 2011 e 2021

Introduction The cardiovascular diseases are the main death cause in Portugal and Cardiovascular Risk Scores are very useful to the primary prevention of these diseases. Prevention of the development and progression of diseases with high morbidity and mortality to the workers can be work out by Occupational Health, in the sense of preserving workers’ health and wellbeing. Objectives The aim of this study is to evaluate the Cardiovascular Risk of the workers of a Hospital Centre in the interval between 2011 till 2021. Methods The Cardiovascular Risk was evaluated by using SCORE-2. Workers were selected only if they worked through the entirety of this interval in this Hospital Centre. The SCORE-2’s exclusion criteria include previous cardiovascular disease, Diabetes mellitus, age lower than 40 years or higher than 69 years. SCORE-2 uses data from blood pressure, lipid panel, sex, age and tobacco use. Results There were selected 345 workers. The median cardiovascular risk of the workers in 2021 (Median=2,215%; InterQuartile Range=3,0%) was significatively higher than the cardiovascular risk of 2011 (M=1,273%; IQR=1,8%). The cardiovascular risk in 2021 of the workers from Administrative Department (M=3.173%; IQR=4.6%) was significatively higher than workers from Medical Department (M=1.958%; IQR=1.9%). There were no significant differences found of the workers’ cardiovascular risk among the professional group in 2011 [X2(7)=7,580; p>0,05] and in 2021 [X2(7)=7,427; p>0,05]. There were no significant differences found of the workers’ cardiovascular risk among the educational background in 2011 [X2(5)=3,412; p>0,05] and in 2021 [X2(5)=2,895; p>0,05]. Conclusions Knowledge about the working population characteristics allows the development of personalized planning regarding healthy lifestyles, to reduce the Cardiovascular Risk of these workers. With these plans designed to reduce the global Cardiovascular Risk of the working population and its consequences on their health, is predicted a reduction in sickness absenteeism, an improvement in the workers’ quality of life, better performance and consequently better services provided by the employer.

Global cardiovascular risk, COVID-19 severity and post-COVID-19 syndrome: a clinical study.

Post-COVID-19 is a syndrome defined by signs and symptoms present until 12 weeks after COVID-19, lasting for more than 8 weeks, not explained by an alternative diagnosis. The present study aimed to assess whether the cardiovascular risk (CVR) of patients with COVID-19 correlates with symptoms and changes in respiratory function parameters in post-COVID-19. The association between CVR and the severity of acute disease was also considered. Between 21/04/21-01/09/21, we enrolled 1,782 consecutive patients with COVID-19. We divided these subjects into (i) 4 levels, based on the severity of COVID-19 (home care; hospitalized/no oxygen therapy; hospitalized/oxygen therapy; hospitalized/NIV-ICU), (ii) 2 levels, according to CVR calculated with the European Society of Cardiology SCORE tables (low-intermediate risk; high or very high risk). All subjects underwent a 3-month follow-up considering post-COVID-19 symptoms. In post-COVID-19 patients, high or very-high CVR was associated with (i) increased risk of hospitalization for COVID-19 (p<0.0001), (ii) higher prevalence of severe clinical manifestations and ICU admission (p<0.0001), (iii) development of post-COVID-19 (p<0.0001) and (iv) increased risk of a larger post-COVID-19 burden of disease. We found a statistically significant association between CVR, severity of COVID-19, and post-COVID-19 syndrome three months after the end of acute disease.

The Role of Perivascular Adipose Tissue in the Pathogenesis of Endothelial Dysfunction in Cardiovascular Diseases and Type 2 Diabetes Mellitus.

Cardiovascular diseases (CVDs) and type 2 diabetes mellitus (T2DM) are two of the four major chronic non-communicable diseases (NCDs) representing the leading cause of death worldwide. Several studies demonstrate that endothelial dysfunction (ED) plays a central role in the pathogenesis of these chronic diseases. Although it is well known that systemic chronic inflammation and oxidative stress are primarily involved in the development of ED, recent studies have shown that perivascular adipose tissue (PVAT) is implicated in its pathogenesis, also contributing to the progression of atherosclerosis and to insulin resistance (IR). In this review, we describe the relationship between PVAT and ED, and we also analyse the role of PVAT in the pathogenesis of CVDs and T2DM, further assessing its potential therapeutic target with the aim of restoring normal ED and reducing global cardiovascular risk.

Carotid Intima-Media Thickness and Its Correlation With Echocardiographic Left Ventricular Function and Geometry in Hypertensive Individuals: A Cross-Sectional Study.

Background It is important to consider left ventricular hypertrophy (LVH) and carotid intima-media thickness (CIMT) in assessing hypertensive patients' global cardiovascular risk profile, as LVH and arterial wall changes occur concurrently. This study aimed to assess the relationship between CIMT and left ventricular geometry and function in hypertensive patients. Methodology This cross-sectional study included 200 hypertensive individuals and sought to correlate their CIMT with left ventricular geometry and function in Lagos University Teaching Hospital. Hypertension was defined as blood pressure ≥140/90 mmHg or on treatment for hypertension presenting at the outpatient clinics. Patients who satisfied the inclusion criteria were recruited. Abnormal CIMT was defined as >0.9 mm. Patients' demographic data were obtained in addition to general characteristics, physical examination, transthoracic echocardiography, and CIMT. The statistical relationship between CIMT and left ventricular geometry and function was obtained and analyzed. Results Normal geometry and LVH were observed in 50.5% and 15.5%, respectively. Left ventricular geometry was associated with abnormal CIMT (χ2 = 31.688, p < 0.001). Furthermore, the mean left ventricular mass index was statistically different between abnormal and normal CIMT (97.84 ± 30.5 vs. 80.75 ± 15.6; p < 0.001). Regardingleft ventricular function, there was no significant difference in E-point septal separation, left ventricular fractional shortening, and left ventricular ejection fraction in abnormal versus normal CIMT groups. However, there was a significant association of CIMT with grades of diastolic dysfunction (χ2 = 7.069, p = 0.029). Additionally, individual parameters of diastolic dysfunction such as left atrial volume index and septal mitral were significantly different (p < 0.001). Conclusions There was an association between age, left ventricular geometry, diastolic function, and CIMT in hypertensive individuals. Therefore, it is beneficial to evaluate CIMT and for these patients to receive more targeted blood pressure control which may reduce the risk of cardiovascular diseases.
