Impact of three-month treatment with pitavastatin on arterial stiffness in patients with hypercholesterolemia: a prospective observational study

ObjectiveAlthough several studies have highlighted the benefits of statins in improving arterial stiffness, there is limited research on whether pitavastatin, a more recently developed statin, has similar effects. This study aimed to investigate the impact of pitavastatin on arterial stiffness in patients with hypercholesterolemia. MethodsThis prospective study enrolled 115 patients with hypercholesterolemia (mean age, 59 years; 22% female) who had not previously been treated with statins. Participants underwent lifestyle interventions followed by administration of pitavastatin (2 or 4 mg daily) if target low-density lipoprotein (LDL) cholesterol levels were not achieved. The primary outcome measured was the change in brachial-ankle pulse wave velocity (baPWV) from baseline after three months of treatment. ResultsPitavastatin treatment significantly reduced LDL cholesterol by 41.1% (from 158 ± 28 to 93.0 ± 29.6 mg/dL; P < 0.001). Additionally, systolic blood pressure (SBP) decreased significantly from 130 ± 14 to 126 ± 14 mmHg (P < 0.001), representing a 2.9% reduction, and baPWV decreased significantly from 1522 ± 325 to 1407 ± 289 cm/s (P < 0.001), a 7.6% reduction. There was a significant correlation between changes in SBP and changes in baPWV (r = 0.565; P < 0.001). Even after adjusting for changes in SBP, the reduction in baPWV induced by pitavastatin remained statistically significant (P < 0.001). ConclusionA three-month treatment with pitavastatin effectively reduced arterial stiffness in patients with hypercholesterolemia, alongside significant improvements in lipid profiles and blood pressure reductions. These findings support the use of pitavastatin for managing key cardiovascular risk factors.

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.

The Effectiveness of Exercise in Reducing Cardiovascular Risk Factors Among Adults: A Systematic Review and Meta-Analysis.

Cardiovascular disease (CVD) remains one of the major causes of sickness and death in the world. However, lifestyle modifications, such as exercise, can significantly reduce the risk of this disease. This study aimed to assess the effectiveness of various forms of physical activity in reducing CVD risk factors among adults. A comprehensive search of the databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials (CENTRAL), and Excerpta Medica Database (EMBASE) databases was conducted between January 1, 2014, and May 31, 2024, as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Randomized controlled trials (RCTs), cohort studies, and observational studies on the impact of aerobic, resistance, or combined training on cardiovascular risk factors in adults (≥18 years) were considered for inclusion. Data relating to primary outcomes, including stroke and myocardial infarction rates, BP, cholesterol levels, and BMIwere collected. The Cochrane risk-of-bias tool and the Methodological Index for Non-Randomized Studies (MINORS) checklist were used for quality and bias assessment. Meta-analyses were performed using the RevMan software, with heterogeneity evaluated by I² statistics; 17 studies, including 11 RCTs and six cohort studies, met the inclusion criteria. There was a significant reduction in the mean systolic BP (SBP) by 3.32 mmHg [95% confidence interval (CI): 0.85-5.78 mmHg; p<0.0001] and mean diastolic BP (DBP) by 2.99 mmHg (95% CI: 2.34-3.64 mmHg; p < 0.00001) after exercise interventions. Moreover, cholesterol levels and BMI values improved with exercise. Those who exercised had a lower risk of stroke or heart attack compared with the controls [odds ratio (OR): 0.57; 95% CI: 0.28-1.14; p >0.0001], although there was substantial heterogeneity in effect size across the studies (I² = 98%). Different types of physical activity (i.e., aerobic, resistance, or combined exercise) can effectively reduce key cardiovascular risk factors, including BP, cholesterol levels, and BMI values. Regular physical activity is still regarded as the most effective preventive measure against CVD, despite inconsistencies in research findings. Future studies should aim to identify optimal exercise programs and their long-term effects on diverse populations.

The Effects of Body Cold Exposure (Cryolipolysis) on Fat Mass and Plasma Cholesterol.

This study investigates the impact of cryolipolysis on reducing localized fat and altering plasma lipid profiles in 30 overweight and obese women. Conducted at the Health Technology Laboratory of the Evangelical University of Goiás, this clinical research adhered to stringent ethical guidelines. Participants underwent three cryolipolysis sessions, with comprehensive assessments of body composition and plasma lipids performed pre- and post-intervention. Significant findings include a reduction in abdominal fat mass by an average of 4.1 kg and a decrease in BMI by 0.7 points (p < 0.05). Notably, total cholesterol levels decreased by an average of 15.7 mg/dL, and LDL cholesterol saw a reduction of 10.2 mg/dL (p < 0.01), with no significant changes in HDL cholesterol or triglyceride levels. These results suggest that cryolipolysis, in conjunction with standardized dietary control, offers a non-invasive alternative to surgical fat reduction, potentially mitigating cardiovascular risks associated with obesity. The study confirms the efficacy of cryolipolysis in targeted fat reduction and underscores its role in improving key cardiovascular risk factors. These findings warrant further exploration into the long-term benefits of cryolipolysis in metabolic health management and not only for aesthetic treatments.

The Influence of Balneotherapy Using Salty Sulfide-Hydrogen Sulfide Water on Selected Markers of the Cardiovascular System: A Prospective Study.

Background: The sulfide-hydrogen sulfide brine balneotherapy (HSBB), including a combination of dissolved hydrogen sulfide (H2S) gas, inorganic sulfur ions (S2-), and hydrosulfide ions (HS-), is one of the most important and most effective forms of spa treatment in patients with osteoarticular disorders (OADs). Some cardiovascular diseases (CVDs) are often considered to be contraindications to HSBB since the presence of thiol groups may lead to an increased quantity of reactive oxygen species (ROS), which damage the vascular endothelium, and endothelial dysfunction is considered to be the main cause of atherosclerosis. However, there are a number of literature reports suggesting this theory to be false. H2S is a member of the endogenous gaseous transmitter family and, since it is a relatively recent addition, it has the least well-known biological properties. H2S-NO interactions play an important role in oxidative stress in CVDs. The general objective of this study was to assess the cardiovascular safety of HSBB and analyze the effect of HSBB on selected cardiovascular risk markers. Methods: A total of 100 patients at the age of 76.3 (±7.5) years from the Włókniarz Sanatorium in Busko-Zdrój were initially included in the study. The following parameters were assessed: age, sex, height, body weight, body surface area (BSA), body mass index (BMI), systolic (SBP) and diastolic blood pressure (DBP), heart rate, the diagnosis of OAD that was the indication for balneotherapy, creatinine (CREAT), glomerular filtration rate (GFR), lipid panel, C-reactive protein (CRP), uric acid (UA), and fibrinogen (FIBR) and cardiovascular markers: (cardiac troponin T (cTnT), N-terminal pro-B-type natriuretic peptide (NT-proBNP). Results: A significant decrease in DBP and a trend towards SBP reduction were observed over the course of the study. A significant decrease was observed in CRP levels decreasing from 2.7 (±3.6) mg/L to 2.06 (±1.91) mg/L, whereas FIBR rose significantly from 2.95 (±0.59) g/L to 3.23 (±1.23) g/L. LDL-C levels decreased slightly, statistically significant, from 129.36 (±40.67) mg/dL to 123.74 (±36.14) mg/dL. HSBB did not affect the levels of evaluated cardiovascular biomarkers, namely NT-proBNP (137.41 (±176.52) pg/mL vs. 142.89 (±182.82) pg/mL; p = 0.477) and cTnT (9.64 (±4.13) vs. 9.65 (±3.91) ng/L; p = 0.948). A multiple regression analysis of pre-balneotherapy and post-balneotherapy values showed cTnT levels to be independently correlated only with CREAT levels and GFR values. None of the assessed parameters independently correlated with the NT-proBNP level. Conclusions: HSBB resulted in a statistically significant improvement in a subclinical pro-inflammatory state. HSBB has a beneficial effect in modifying key cardiovascular risk factors by reducing LDL-C levels and DBP values. HSBB has a neutral effect on cardiovascular ischemia/injury. Despite slightly elevated baseline levels of the biochemical marker of HF (NT-proBNP), HSBB causes no further increase in this marker. The use of HSBB in patients with OAD has either a neutral effect or a potentially beneficial effect on the cardiovascular system, which may constitute grounds for further studies to verify the current cardiovascular contraindications for this form of therapy.

Forecasting the Economic Burden of Cardiovascular Disease and Stroke in the United States Through 2050: A Presidential Advisory From the American Heart Association.

Quantifying the economic burden of cardiovascular disease and stroke over the coming decades may inform policy, health system, and community-level interventions for prevention and treatment. We used nationally representative health, economic, and demographic data to project health care costs attributable to key cardiovascular risk factors (hypertension, diabetes, hypercholesterolemia) and conditions (coronary heart disease, stroke, heart failure, atrial fibrillation) through 2050. The human capital approach was used to estimate productivity losses from morbidity and premature mortality due to cardiovascular conditions. One in 3 US adults received care for a cardiovascular risk factor or condition in 2020. Annual inflation-adjusted (2022 US dollars) health care costs of cardiovascular risk factors are projected to triple between 2020 and 2050, from $400 billion to $1344 billion. For cardiovascular conditions, annual health care costs are projected to almost quadruple, from $393 billion to $1490 billion, and productivity losses are projected to increase by 54%, from $234 billion to $361 billion. Stroke is projected to account for the largest absolute increase in costs. Large relative increases among the Asian American population (497%) and Hispanic American population (489%) reflect the projected increases in the size of these populations. The economic burden of cardiovascular risk factors and overt cardiovascular disease in the United States is projected to increase substantially in the coming decades. Development and deployment of cost-effective programs and policies to promote cardiovascular health are urgently needed to rein in costs and to equitably enhance population health.

A Cross-Sectional Study on the Epidemiology and Risk Factors of Acute Coronary Syndrome in Northern Iraq.

There is an upward trend in the key cardiovascular risk factors in Iraq. Accordingly, the current study was initiated to address the changing epidemiology of acute coronary heart disease in Iraq. In this cross-sectional study, atotal of 600 patients diagnosed with acute coronary syndrome (ACS) in the period between October 2020 and September 2022, and admitted to the Heart Center at Azadi Teaching Hospital, Duhok, Iraq, were recruited. All patients had detailed histories, clinical examinations, and relevant investigations, with particular scrutiny of the major cardiovascular risk factors at enrollment. Patients were categorized as having ST-segment elevation myocardial infarction (STEMI) or non-ST elevation myocardial infarction (NSTEMI) following theAmerican Society of Cardiology guidelines. The patients had a mean age of 56.2 (SD: 10.5) years, with a male-to-female ratio of 2.5:1. The study included 185 (30.8%) patients with NSTEMI and 415 (69.2%) patients with STEMI. The frequency of regular smokers, those with hyperlipidemia, hypertension, and diabetes mellitus were57.0%, 56.2%, 47%, and 40.7%, respectively. Family history of coronary heart disease and being overweight were encountered in a further 24.8% and 29.8%, respectively. Females were significantly older, with higher frequencies of hypertension, diabetes, hyperlipidemia, and overweight, while they were less likely to be smokers than males. Patients with hypertension, diabetes, and hyperlipidemia were significantly older, while smokers and those with a family history of ischemic heart disease were significantly younger. STEMI patients were significantly younger, more likely to be males, smokers, and overweight, but less likely to be diabetic than NSTEMI patients. Iraqi patients with ACS were eight to 10 years younger than their Western counterparts. Males were more frequently involved and were younger than females. Hyperlipidemia and smoking were the most frequent risk factors, with the former's frequency exceeding reports from neighboring countries and the West. STEMI was more frequent and occurred at younger ages than NSTEMI. The results of the study support the need to institute effective targeted preventive and educational programs to reduce the risk of ACS in this part of the world.

Cardiovascular Disease Prediction from Retinal Images using Machine Learning

The structure and function of the microvascular are significantly influenced by the key cardiovascular disease risk factors of hypertension and heart attacks. Images taken with a fundus camera can be used to spot irregularities in the blood vessels of retina that indicate the extent injury on blood vessels by hypertension and heart attacks. Using machine learning and AI techniques, detecting the preclinical signs that fall below the threshold of an observer. The proposed methodology aimed to investigate the effects of hypertension and heart attacks on morphological characteristics of retinal blood vessels. With a diagnosis of hypertension and heart attack, data scientists collect retinal images. Interference data is removed— information about structures other than that retinal vasculature using the vessel segmentation method, leaving only morphological details about the blood vessel of retina.

NLRP3 inflammasome and pyroptosis in cardiovascular diseases and exercise intervention.

NOD-like receptor protein 3 (NLRP3) inflammasome is an intracellular sensing protein complex that possesses NACHT, leucine-rich repeat, and pyrin domain, playing a crucial role in innate immunity. Activation of the NLRP3 inflammasome leads to the production of pro-inflammatory cellular contents, such as interleukin (IL)-1β and IL-18, and induction of inflammatory cell death known as pyroptosis, thereby amplifying or sustaining inflammation. While a balanced inflammatory response is beneficial for resolving damage and promoting tissue healing, excessive activation of the NLRP3 inflammasome and pyroptosis can have harmful effects. The involvement of the NLRP3 inflammasome has been observed in various cardiovascular diseases (CVD). Indeed, the NLRP3 inflammasome and its associated pyroptosis are closely linked to key cardiovascular risk factors including hyperlipidemia, diabetes, hypertension, obesity, and hyperhomocysteinemia. Exercise compared with medicine is a highly effective measure for both preventing and treating CVD. Interestingly, emerging evidence suggests that exercise improves CVD and inhibits the activity of NLRP3 inflammasome and pyroptosis. In this review, the activation mechanisms of the NLRP3 inflammasome and its pathogenic role in CVD are critically discussed. Importantly, the purpose is to emphasize the crucial role of exercise in managing CVD by suppressing NLRP3 inflammasome activity and proposes it as the foundation for developing novel treatment strategies.

1830. Social determinants of cardiovascular disease risk factor control among people living with HIV

Abstract Background HIV is associated with an elevated risk of cardiovascular disease, yet hypertension and high cholesterol are often sub-optimally treated in people with HIV. The role of racial disparities and social determinants of health in the management of these cardiovascular risk factors is poorly understood. Average systolic blood pressures vs TIS score (hypertension treatment intensity), by Black race TIS (therapeutic intensity score) was calculated by dividing the patient’s antihypertensive medication dosage by the maximum daily dosage approved by the US Food and Drug Administration, then summing this proportion for each antihypertensive medication prescribed. For example, if a patient was prescribed two antihypertensive medications each at 75% of the maximum approved dosage, the TIS score would be calculated as 1.5 (0.75 + 0.75). Methods We performed a cross-sectional analysis of adult patients with HIV among three academic medical centers in the United States. We considered various social determinants of health including race, sex, measures of economic stability, education level, health insurance, health literacy, social deprivation index by zip code, and measures of psychosocial stress. We examined a hybridized outcome of risk factor control (poor or good) and treatment intensity (minimal or maximal) for two key cardiovascular risk factors, hypertension and hyperlipidemia. Multinomial logistic regressions were performed to identify factors associated with cardiovascular risk factor control and intensity, with “good control, maximal treatment” used as the reference group. Results Overall, 371 persons were included in the analysis. Participants were 23.5% female, 59.6% Black, 7.3% Hispanic/Latino, with a median age of 59 (interquartile range 53-64). Among study participants with hypertension, Black participants were more likely to have poor control despite maximal treatment (relative risk ratio [RRR] 2.95, 95% CI: 1.30-6.66). In our hyperlipidemia analysis, having the highest quartile of perceived stress was more common among participants with poor than good cholesterol control (27.0% vs 15.9%, p=0.032). Compared to participants with good control and maximal treatment of high cholesterol, participants with the highest quartile of perceived stress were more likely to have poor control with minimal (RRR: 2.80, 95% CI: 1.02-7.63) or maximal (RRR: 3.64, 95% CI: 1.20-11.1) treatment. Conclusion Race and social determinants of health, including perceived stress, appear to influence cardiovascular disease risk factors among persons with HIV.

Left ventricular hypertrophy and mortality in ethnic minority groups in the UK: e-ECHOES study.

Hypertension is the key modifiable cardiovascular risk factor but is underdiagnosed, and its scale in South Asian and African-Caribbean communities is unknown. Left ventricular hypertrophy (LVH) is a measure of target organ damage in uncontrolled hypertension. The study assesses LVH prevalence in South Asian and African-Caribbean communities and its impact on mortality. This study is based on the large prospective UK community Ethnic-Echocardiographic Heart of England Screening Study (E-ECHOES, age ≥45 years). Left ventricular mass index (LVMI) was calculated using echocardiography to establish LVH. The predictive value of LVH all-cause and cardiovascular mortality was assessed using Cox regression. The study included 3200 South Asians (age 59 ± 10 years, 52% women, 45% had a history of hypertension, 5.8 ± 1.0-year follow-up). LVH was found in 1568 (49%), of whom 45% did not have hypertension diagnosis. On Cox regression, LVH was independently associated with all-cause mortality [hazard ratio 1.38, 95% confidence interval (95% CI) 1.01-1.88], cardiovascular mortality (hazard ratio 2.64, 95% CI 1.21-3.73). The projected overall hypertension prevalence was 82%, undiagnosed hypertension prevalence 37%. The study included 1858 African-Caribbeans (age 62 ± 12, 45% women, 45% had history of hypertension, 5.1 ± 0.9-year follow-up). LVH was found in 1186 (64%), of whom 32% did not have hypertension diagnosis. LVH was borderline associated with all-cause mortality (hazard ratio 1.57, 95% CI 1.01-2.44), but not cardiovascular mortality (hazard ratio 1.82, 95% CI 0.80-4.16). The projected overall hypertension prevalence was 78.5%, and undiagnosed hypertension prevalence was 20.8%. UK South Asians and African-Caribbeans have a high prevalence of hypertension, which is often underdiagnosed and poorly controlled.

41-OR: The Health Effects of a Behavior Change Program for Prediabetes—Quasi-Experimental Evidence from 2.1 Million Primary Care Patients in England

Introduction: There is an urgent need to implement population-based measures that prevent diabetes, enhance its detection, and avert its progression to complications. However, there remains widespread doubt among clinicians that lifestyle counseling provided in routine care can improve health. This study aims to investigate whether the largest behavior change program for pre-diabetes globally (the English Diabetes Prevention Programme) leads to improvements in key cardiovascular risk factors. Methods: We exploited the threshold in HbA1c used to decide on program eligibility by applying a regression discontinuity design, one of the most credible quasi-experimental strategies for causal inference, to electronic health data from the Clinical Practice Research Datalink, covering nearly one fifth of all GP practices in England. Using local linear regression, we compared patients lying closely on either side of the threshold for program entry (HbA1c of 42 mmol/mol [6.0%]). The primary outcome was change in HbA1c. Secondary outcomes were body mass index (BMI), weight, blood pressure, and serum lipids. Results: 2 106 469 adult patients met inclusion criteria in 2017-2018 with follow-up ending June 2020. Program referral led to significant improvement in HbA1c (-0.82 mmol/mol, 95%CI -1.42, -0.21), BMI (-1.34, 95%CI -1.86, -0.81), weight (-2.94 kg, 95%CI -4.33, -1.56), and triglycerides (-0.32 mmol/l, 95%CI -0.53, -0.10). There was suggestive evidence that program referral improved HDL (0.04 mmol/l, 95%CI 0, 0.08). Blood pressure and LDL did not significantly improve. Sensitivity analyses showed that improvements in HbA1c were not attributable to being prescribed medication. Conclusion: By leveraging a threshold rule induced by public health guidelines, this analysis provides causal, rather than associational, evidence that lifestyle counseling implemented in a national health system can achieve important health improvements.

Long term reduction of cardiovascular risk factors associated with three hour daily dialysis: A prospective, cohort study.

Daily hemodialysis (DHD) compared to conventional hemodialysis (CHD) leads to improvements in left ventricular hypertrophy and mineral metabolism at 1-year follow-up. However, there is no information from prospective studies on the long terms effects of DHD on these key cardiovascular risk factors. We conducted a 4 year, prospective cohort study of 26 DHD and 51 matched CHD patients on the effect of DHD (six sessions/week × 3 h) versus CHD (three sessions/week × 4 h), 15 DHD, and 26 CHD patients completed 4-years follow-up. Measures of left ventricular mass index (LVMI), blood pressures, hemoglobin, and mineral metabolism markers were performed. Systolic and diastolic blood pressures were significantly lower in the DHD group than the CHD group at 4-year follow-up, 128 mmHg (95% CI, 111-143) versus 148 mmHg (95% CI, 137-158) (p < 0.05) and 60 mmHg (95% CI, 56-63) versus 71 mmHg (95% CI, 64-76) (p < 0.05). DHD was associated with fewer patients taking any anti-hypertensive drug therapy than CHD, 50% versus 80% (p < 0.05). DHD was associated with improved attainment of mineral metabolism goals for phosphorus (adjusted HR 3.6, p = 0.002) and calcium × phosphorus product (adjusted HR 3.66, p = 0.001) at 4-years follow-up compared to CHD. At 4 years, there was a nonsignificant trend toward lower LVMI in the DHD than in the CHD group: 116 g/m2 (95% CI, 97-136) versus 138 g/m2 (95% CI, 115-172) (p = 0.23). Similarly, improvements in hemoglobin also persisted at 4 years follow-up. DHD is associated with long-term (4 year) improvements in key cardiovascular risk factors: blood pressure, mineral metabolism, and anemia with trends toward improved LVMI.

Community echocardiographic left ventricular hypertrophy and mortality in South Asians in the UK: E-ECHOES study

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): British Heart Foundation (PG/05/036) Primary Care Research Network-Central England. Background People of South-Asian origin have high cardiovascular morbidity, contributed by health inequalities. Hypertension is the key modifiable cardiovascular risk factor but is underdiagnosed, but its scale in South Asian communities is unknown. Left ventricular hypertrophy (LVH) on echocardiography is a measure of target organ damage related to uncontrolled hypertension. The study aims to assess prevalence of LVH in South Asian community and its impact on mortality. This study is based on the large prospective UK community Ethnic-Echocardiographic Heart of England Screening Study (E-ECHOES, age ≥45 years). Methods Left ventricular mass index (LVMI) was calculated using echocardiography. LVH was established as increased LVMI. Predictive value of LVH all-cause and cardiovascular mortality was assessed using Cox regression. Results The study included 3200 South Asians (age 59±10, 52% women, 45% had a history of hypertension). There were 182 deaths, including 64 cardiovascular deaths during a 5.8±1.0-year follow-up. LVH was found in 1568 (49%). In those with LVH, 705 (45%) did not have a diagnosis of hypertension. On Cox regression LVH was independently associated with all-cause mortality (hazard ratio [HR] 1.38, 95% confidence interval [CI] 1.01-1.88), cardiovascular mortality (HR 2.64, 95% CI 1.21-3.73). The projected overall hypertension prevalence was 82%. Conclusion South Asians in the UK have a very high prevalence of hypertension which is often underdiagnosed and poorly controlled, leading to LVH and excess in overall and cardiovascular mortality. The findings call for more effective screening and management of hypertension with lower BP targets.

Chest pain observation unit: A missed opportunity to initiate smoking cessation therapy

BackgroundEmergency Department Observation Unit (EDOU) patients with chest pain have a high prevalence of smoking, a key cardiovascular disease risk factor. While in the EDOU, there is an opportunity to initiate smoking cessation therapy (SCT), but this is not standard practice. This study aims to describe the missed opportunity for EDOU-initiated SCT by determining the proportion of smokers who receive SCT in the EDOU and within 1-year of EDOU discharge and to evaluate if SCT rates vary by race or sex. MethodsWe performed an observational cohort study of patients ≥18 years old being evaluated for chest pain in a tertiary care center EDOU from 3/1/2019–2/28/2020. Demographics, smoking history, and SCT were determined by electronic health record review. Emergency, family medicine, internal medicine, and cardiology records were reviewed to determine if SCT occurred within 1-year of their initial visit. SCT was defined as behavioral interventions or pharmacotherapy. Rates of SCT in the EDOU, 1-year follow-up period, and the EDOU through 1-year of follow-up were calculated. SCT rates from the EDOU through 1-year were compared between white vs. non-white and male vs. female patients using a multivariable logistic regression model including age, sex, and race. ResultsAmong 649 EDOU patients, 24.0% (156/649) were smokers. These patients were 51.3% (80/156) female and 46.8% (73/156) white, with a mean age of 54.4 ± 10.5 years. From the EDOU encounter through 1-year of follow-up, only 33.3% (52/156) received SCT. In the EDOU, 16.0% (25/156) received SCT. During the 1-year follow-up period, 22.4% (35/156) had outpatient SCT. After adjusting for potential confounders, SCT rates from the EDOU through 1-year were similar among whites vs. non-whites (aOR 1.19, 95% CI 0.61–2.32) and males vs. females (aOR 0.79, 95% CI 0.40–1.56). ConclusionsSCT was rarely initiated in the EDOU among chest pain patients who smoke and most patients who did not receive SCT in the EDOU never received SCT at 1-year of follow-up. Rates of SCT were similarly low among race and sex subgroups. These data suggest an opportunity exists to improve health by initiating SCT in the EDOU.

Predicting Hypertension using Machine Learning: A Case Study at Petra University

Hypertension is a key cardiovascular disease risk factor (CVD). Identifying these high-risk individuals is crucial since it would save time and money before using any sophisticated, invasive, or costly diagnostic technique. This endeavour may be accomplished in part with the use of modern machine learning techniques. Specifically, a prediction model may be created based on several easily-obtained, non-invasive, and inexpensive indicator characteristics of high-risk individuals. This research is an effort to forecast hypertension risks based on Petra University’s population. This case study was done between 2019 and 2020 at Petra University. Using hospital-visited patients’ medical records, the gathered data was used to develop a model. The research comprised a comprehensive dataset of 31500 patients, comprising 12658 hypertension cases and 18842 non-hypertensive cases. SMOTE was used as a dataset for the categorization of hypertension. The SMOTE-k-nearest neighbour prediction model performs exceptionally well, as evidenced by its excellent performance (83.9% classification accuracy, 85.1% specificity, 83.3% sensitivity, and 89.6% AUC) when compared to other classifiers using 10-fold cross-validation with full features and no oversampling on the hypertension dataset. The data extracted from Petra University Health Center is considered to be very helpful for ML and is availed to produce a decision tree to identify the data related to hypertension.

Physical Activity Is Associated with Slower Cognitive Decline in Older Adults with Type 2 Diabetes.

Physical activity is associated with slower cognitive decline in old age. Type 2 diabetes (T2d) is a risk factor for dementia and cognitive decline. Physical activity protects against several T2d complications. Yet, little is known about the contribution of physical activity to cognitive health among the elderly with T2d. To examine the association between physical activity and cognitive decline in older adults with T2d. This is a prospective longitudinal study using data from the Israel Diabetes and Cognitive Decline (IDCD) study. ICDC study (N=1,213), is a population-based cohort of adults over the age of 65, diagnosed with type 2 diabetes, who were cognitively normal at baseline and followed up every 18 months. Participants with at least one follow-up assessment who were in the same physical activity group consistently and had complete demographic data. Physical activity was measured using Minnesota Leisure Time Activity Questionnaire, cognitive functioning was measured using a broad neuropsychological assessment measuring Executive Functioning, Attention/Working Memory, Semantic Categorization and Episodic Memory. Participants were classified into physical activity groups based on self-reported physical activity at baseline and all follow ups: "active" - participation in recreational physical activity (n=286); "non-active"- the only physical activity was walking from place to place (n=93) and "sedentary" (n=19). Linear mixed effects models were applied to adjust for key demographic and cardiovascular risk factors. Participants were 72.4 (SD 4.6) years old, had 13.3 (SD 3.6) years of education, and 163 (41%) were female. In the fully adjusted model, compared to the non-active group the active group had significantly slower rate of decline in Global Cognition (p=0.005), Executive Functioning (p=.014), and Attention/Working Memory (p=.01). There were no significant group differences for Semantic Categorization (p=.17) and Episodic Memory (p=.88). Among initially cognitively normal and independent older adults with T2d, a physically active lifestyle was associated with a slower rate of cognitive decline. Future research should examine whether promoting physical activity may prevent or delay onset of dementia in this high-risk population.

Current possibilities of influencing the main cardiovascular risk factors in patients with type 2 diabetes mellitus

Background. Cardiovascular morbidity increases notably among patients with diabetes. A correlation between leptin resistance and cardiovascular risk was found in patients with arterial hypertension and metabolic syndrome. However, there are no data about the influence of empagliflozin on leptin level; empagliflozin effectiveness against key cardiovascular risk factors in diabetic patients with normal weight and overweight has not been studied yet. The purpose of this work was to study the impact of comprehensive treatment using metformin and empagliflozin on the main cardiovascular risk factors in patients with type 2 diabetes mellitus with different body weights. Materials and methods. Ninety-seven patients with type 2 diabetes with normal weight, overweight and obesity were examined. Anthropometric indicators were taken. The parameters of carbohydrate and lipid metabolism, the level of leptin in blood serum were determined and the HOMA-IR was calculated. Results. Insulin resistance in all groups of patients was associated with abdominal obesity, hyperleptinemia (r=0.505, p&lt;0.05; r=0.846, p&lt;0.05; r=0.886, p&lt;0.05 in patients of groups I–III). After a 6-month course of treatment with metformin and empagliflozin, body weight and waist circumference significantly decreased in overweight and obese patients, and no significant changes between groups were found in those with a normal body mass index. A reliable positive effect of comprehensive treatment on indicators of carbohydrate metabolism, systolic blood pressure, regardless of the patient’s weight, was noted. Under the influence of comprehensive treatment with the use of empagliflozin, the level of leptin (p&lt;0.05) and HOMA-IR (p&lt;0.05) also decreased significantly in patients of all groups, regardless of body mass index. Conclusions. It was found that the combined use of metformin and empagliflozin for 6 months had a reliable effect on the modified cardiovascular risk factors in patients with type 2 diabetes of different weights.

May Measurement Month 2017-2019: an analysis of blood pressure screening results from Ukraine.

Hypertension is a key cardiovascular disease risk factor leading to premature mortality worldwide. The purpose of the May Measurement Month (MMM) campaign in Ukraine is to improve awareness of hypertension at the individual and population level. Adults (≥18 years) were screened at sites in Ukraine. Data from the MMM17 (19 sites), MMM18 (1 site), and MMM19 (5 sites) campaigns are included in the present analysis. Ideally, three blood pressure (BP) measurements were taken for each participant, and data on lifestyle factors and comorbidities were collected. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mm Hg (based on the mean of the second and third readings) or being on antihypertension medication. Multiple imputation was used to estimate participants’ mean BP where readings were missing. Linear regression models were used to evaluate associations between BP and participant characteristics. Of all 46 549 screenees, 33 307 (71.6%) had hypertension, and 82.6% of whom were on antihypertensive medication. Of all those on medication, 31.4% were controlled to BP < 140/90 mmHg, and of all 33 307 participants with hypertension, 25.9% had controlled BP. Of all participants, 6.6% took statins and 11.2% took aspirin. The analysis of the MMM 2017, 2018, and 2019 campaigns has shown a high proportion of hypertension, insufficient level of awareness, and critically low level of effective BP control in Ukraine. Further MMM screening is needed to increase awareness of high BP and to help improve diagnosis, management, and treatment of hypertension.

Prevalence of cardiovascular risk factors by HIV status in a population-based cohort in South Central Uganda: a cross-sectional survey.

IntroductionCardiovascular disease is one of the leading causes of mortality for people living with HIV, but limited population‐based data are available from sub‐Saharan Africa. This study aimed to determine the prevalence of key cardiovascular disease risk factors, 10‐year risk of cardiovascular disease and type 2 diabetes mellitus through risk scores by HIV status, as well as investigate factors associated with hyperglycaemia, hypertension and dyslipidaemia in South‐Central Uganda.MethodsA cross‐sectional study was conducted in 37 communities of the population‐based Rakai Community Cohort Study from May 2016 to May 2018. In total, 990 people living with HIV and 978 HIV‐negative participants aged 35–49 years were included. Prevalence estimates and 10‐year cardiovascular and type 2 diabetes risk were calculated by sex and HIV serostatus. Multivariable logistic regression was used to determine associations between socio‐demographic, lifestyle and body composition risk factors and hyperglycaemia, hypertension and dyslipidaemia.ResultsOverweight (21%), obesity (9%), abdominal obesity (15%), hypertension (17%) and low high‐density lipoprotein (HDL) (63%) were the most common cardiovascular risk factors found in our population. These risk factors were found to be less common in people living with HIV apart from hypertension. Ten‐year risk for cardiovascular and type 2 diabetes mellitus risk was low in this population with <1% categorized as high risk. In HIV‐adjusted multivariable analysis, obesity was associated with a higher odds of hypertension (odds ratio [OR] = 2.31, 95% confidence interval [CI] 1.35–3.96) and high triglycerides (OR = 2.08, CI 1.25–3.47), and abdominal obesity was associated with a higher odds of high triglycerides (OR = 2.55, CI 1.55–4.18) and low HDL (OR = 1.36, CI 1.09–1.71). A positive HIV status was associated with a lower odds of low HDL (OR = 0.43, CI 0.35–0.52).ConclusionsIn this population‐based study in Uganda, cardiovascular risk factors of obesity, abdominal obesity, hypertension and dyslipidaemia were found to be common, while hyperglycaemia was less common. Ten‐year risk for cardiovascular and type 2 diabetes mellitus risk was low. The majority of cardiovascular risk factors were not affected by HIV status. The high prevalence of dyslipidaemia in our study requires further research.
