Secondary prevention of coronary heart disease in elderly population of Turkey: A subgroup analysis of ELDERTURK study

Risk factor control and adherence to recommended Lifestyle among US hypertension patients

BACKGROUND

Although hypertension is a significant public health challenge globally, only a few studies have assessed the effectiveness of risk factor control and adherence to recommended lifestyle among United States hypertension patients.

METHODS

In this study, a detailed, stratified analysis of the 1999-2018 National Health and Nutrition Examination Survey was conducted to assess the adequacy of risk factor control and conformity to recommended lifestyle among United States patients with hypertension. Logistic regression analysis was used to identify influencing factors associated with not acheving risk factors and lifestyle targets.

RESULTS

A total of 21,770 participants (mean age, 62 ± 15 years) were enrolled in this study. About one in five (20%) participants achieved the recommended body mass index goal, 40% achieved the low-density lipoprotein cholesterol goal, and 30% achieved the recommended waist circumference. Most patients (80%) achieved the recommended smoking goal, 58% met the recommended alcohol consumption, and 19% achieved the recommended physical activity goal. Multivariate analysis demonstrated that age, gender, race, education, metabolic syndrome, and diabetes mellitus were independent predictors of not achieving risk factors and lifestyle targets.

CONCLUSIONS

Controlling risk factors and adherence to recommended lifestyles are not ideal for hypertension patients. Therefore, further research should assess how to improve the compliance rate and take targeted measures based on influencing factors for long-term prognosis.

The secondary prevention of coronary heart disease in US adults 75 Years and older in daily practice: Results from the National Health and Nutrition Examination Survey 1999-2018 survey

Background

Pharmacologic therapies, risk factor control, and lifestyle alterations were independently proven to reduce long-term cardiovascular events. However, comprehensive research examining the extent to which individuals aged 75 and above in the United States adhere to national guidelines for the secondary prevention of coronary heart disease is limited. Therefore, the primary objective of this study was to examine the current state of secondary prevention of coronary heart disease in persons 75 years of age and older in the United States and to examine the factors that contribute to inadequate drug utilization and poor control of numerous risk factors.

Methods

We identified patients over 75 years of age with coronary heart disease based on the National Health and Nutrition Examination Survey from 1999 to 2018 and analyzed the adequacy of risk factor control and adherence to lifestyle and medication recommendations to assess the effectiveness of coronary heart disease management. Logistic regression analysis was used to identify factors associated with uncontrolled risk factors or noncompliance with recommended medications.

Results

We collected information from 1566 known coronary heart disease patients aged ≥75 years of age. The majority were at target goals for blood pressure (58.88%), low-density lipoprotein cholesterol (66.85%), and glycated hemoglobin (76.12%). Only 27.8% and 36.06% were at targets for body mass index and waist circumference, respectively. 91.95% reported smoking cessation, 85.98% followed recommended alcohol consumption, whereas only 10.34% reported sufficient physical activity. For β blockers, angiotensin -converting enzyme inhibitors/angiotensin receptor blockers, statins, and antiplatelet drugs, the utilization of indicated therapy was 54.41%, 49.36%, 54.79%, and 19.03%, respectively (6.26% for all 4 medications). The results of the logistic regression analysis demonstrated that diabetes mellitus and metabolic syndrome were critical markers of numerous uncontrolled risk variables as well as noncompliance with medication regimens.

Conclusions

A vast majority of coronary heart disease patients ≥75 years in the USA exhibited suboptimal overall control of critical coronary heart disease risk factors. For this patient population, more knowledge is necessary to enable patients to receive continuous support, guidance, and counseling.

The effect of web-based education delivered as part of cardiac rehabilitation on healthy lifestyle behaviors, and quality of life in patients with coronary artery disease in Turkey: A randomised controlled trial

OBJECTIVE

This study was conducted to evaluate the effect of web-based education delivered as part of cardiac rehabilitation (CR) on healthy lifestyle behaviors, and quality of life in patients with coronary artery disease (CAD) in Turkey.

METHOD

This study is a randomized controlled trial. The experimental group (n = 35) received web-based education and telephone counseling for 12 weeks after discharge, while the control group (n = 35) received standard care.

RESULTS

Post-test healthy lifestyle behaviors scale total score and total scores of all sub-dimensions except nutrition were higher in the experimental group (p < 0.05). The post-test international physical activity total score, and VAS scale scores of the experimental group and were significantly higher (p < 0.05). The number of non-smoking patients in the post-test was statistically significantly higher in the experimental group (p < 0.05).

CONCLUSION

The results showed that web-based education delivered as part of CR in a Turkish hospital improved healthy lifestyle behaviors, physical activity level, and quality of life in CAD.

PRACTICE IMPLICATIONS

Our study proved that web-based education delivered as part of CR, nurse follow-up, and telephone counseling services may be effective tools for CAD patients to adhere to healthy lifestyle behaviors, and to promote quality of life and smoking cessation.

Web-Based Interventions to Promote Healthy Lifestyles for Older Adults: Scoping Review

Background

With the aging of the population and rising rates of chronic diseases, web-based interventions could be considered to support older adults in adopting healthy lifestyles. To date, published knowledge syntheses have focused on quantitative studies among older adults aged ≥50 years. However, those aged ≥65 years may have different needs to be met by these interventions because of the biological and physiological changes associated with aging, and qualitative studies could help advance knowledge in this field.

Objective

The objective of this scoping review is to explore the extent of the literature on web-based interventions aimed at promoting healthy lifestyles among people aged ≥65 years.

Methods

A scoping review was conducted based on the framework proposed by Levac et al. Six databases (ie, MEDLINE, CINAHL, PsycINFO, Web of Science, the Cochrane Database of Systematic Reviews, and the Joanna Briggs Library) and gray literature (ie, Google Scholar and OpenGrey) were searched. The final search was conducted on June 23, 2021. The studies were selected by 2 persons (AL and ML) independently. The included studies were systematic reviews and qualitative and quantitative studies focusing on web-based interventions to promote healthy lifestyles in people aged ≥65 years that were published in French or English between 1990 and 2021. Data were extracted in a table and synthesized based on the conceptualization of web-based interventions (ie, according to the use parameters, behavior change techniques, delivery modes, and theories). A thematic analysis was performed.

Results

In total, 20 articles were included in this review, which represents studies focused on 11 distinct interventions. All of the interventions (11/11, 100%) aimed to promote physical activity among older adults. The number of intervention sessions varied from 5 to 16, with a frequency from daily to once every 2 weeks. Diverse delivery modes such as electronic diary, video, and phone call were found. The most used behavior change techniques were instruction, feedback, and self-monitoring. Few interventions (6/11, 55%) were based on a theory. A favorable trend was observed in increasing physical activity, and 5 themes emerged that appeared to be central to behavior change among older adults: motivation, support, tailoring, barriers, and perceptions.

Conclusions

This scoping review provides a better understanding of the components of web-based interventions and their outcomes on the healthy lifestyles of people aged ≥65 years. These findings could provide important guidance for the design and development of future web-based interventions in this field. Further research is needed to continue the development and evaluation of innovative and accessible interventions to promote healthy lifestyles among older adults.

Predictive Value of CHA2DS2 -VASc-HSF Score for Severity of Acute Coronary Syndrome

CHADS₂ and CHA₂DS₂-VASc scores have been used to assess the prognostic risk of thromboembolism in non-valvular atrial fibrillation patients. Recent studies have shown the utility of CHADS₂ and CHA₂DS₂-VASc scores for evaluating the severity of coronary artery disease (CAD). The newly defined CHA₂DS₂-VASc-HSF score evaluates atherosclerosis and is associated with CAD severity. This study investigated the association between the CHA₂DS₂-VASc-HSF score and acute coronary syndrome (ACS) severity as assessed by the Gensini score and the number of vessels. Furthermore, this study also compared the diagnostic value of the CHADS₂, CHA2 DS2-VASc, and CHA₂DS₂-VASc-HSF score for ACS. A total of 2367 eligible inpatients (ACS group [n = 2030]; non-CAD group [n = 337]) were consecutively enrolled in this study. Receiver operating characteristic curve diagnostic tests and logistic regression models were used to analyze the risk factors for ACS. The CHADS₂, CHA₂DS₂-VASc, and CHA₂DS₂-VASc-HSF scores were significantly higher in the ACS group than those in the control group. After adjusting for numerous traditional CAD risk factors, an increased CHA₂DS₂-VASc-HSF score was found to be an independent risk factor for patients with ACS (odds ratio 1.401, 95% confidence interval 1.044, −1.879; P < 0.05). A newly diagnosed CHA₂DS₂-VASc-HSF score predicts the severity of ACS.

Secondary prevention of coronary heart disease: The effect of a nursing intervention using Cox's interaction model of client health behaviour

AIMS

Secondary prevention of coronary heart disease is of utmost importance to facilitate people to achieve health outcomes and behaviours. This study was to investigate the effect of a nursing intervention based on Cox's interaction model of client health behaviour to improve health outcomes and behaviours of secondary prevention of coronary heart disease.

DESIGN

This study is a cluster randomised controlled trial.

METHODS

Participants were recruited between August and November 2019 in two community settings in Hengyang city, Hunan province, China. Participants in the intervention group received a nursing intervention based on Cox's interaction model of client health behaviour and routine health education, while those in the control group received routine health education only. The outcome variables included selfߚmanagement, physical activity, medication compliance, anxiety, sexual knowledge, the ability to identify sexual health education needs, blood pressure, body mass index (BMI), and lowߚdensity lipoprotein cholesterol (LDLߚC). The influential statistical tests applied to analyse the data included χ² tests and t tests.

RESULTS

Seventyߚseven participants completed this study. Compared with the control group (n = 40), the intervention group (n = 37) showed statistically significant better health outcomes and behaviours regarding selfߚmanagement, physical activity (except for high energy consumption), medication compliance, anxiety, sexual knowledge, the ability to identify sexual health education needs, systolic blood pressure, BMI, and LDLߚC. However, there was no statistically significant difference in diastolic blood pressure and high energy consumption for physical activity.

CONCLUSION

A wellߚdeveloped nursing intervention based on Cox's interaction model of client health behaviour could successfully improve health outcomes and behaviours of secondary prevention of coronary heart disease. Such an intervention may be incorporated into community healthcare practice by nurses to improve patient care.

IMPACT

This study provides a valuable insight to facilitate further development of effective nursing interventions to improve secondary prevention of coronary heart disease in community settings.

Assessment of the ability of the CHA2DS2-VASc scoring system to grade left atrial function by 2D speckle-tracking echocardiography

Background

The CHA₂DS₂-VASc scoring system is correlated with left atrial (LA) reservoir function in patients with atrial fibrillation (AF) rhythm or paroxysmal AF. We assessed the ability of CHA₂DS₂-VASc to grade LA function in patients with sinus rhythm who were candidates for coronary artery bypass grafting (CABG).

Methods

This cross-sectional study recruited 340 consecutive candidates for CABG and categorized them according to their CHA₂DS₂-VASc scores as mild-, moderate-, and high-risk score groups with 34 (10%), 83 (24%), and 223 (66%) patients, respectively. LA function was evaluated via 2D speckle-tracking echocardiography in terms of global longitudinal strain and strain rate during the reservoir, conduit, and contraction phases. In-hospital mortality, postoperative AF, prolonged intensive care unit (ICU) stay, and prolonged mechanical ventilation were assessed.

Results

LA strain and strain rate during the reservoir phase was statistically significantly lower in the high-risk score group than the low- and moderate-risk score groups (27.8 ± 6.9% vs 31.0 ± 5.0% vs 29.8 ± 6.1%, respectively; P = 0.004 and 2.6 ± 0.7 s⁻¹ vs 2.9 ± 0.6 s⁻¹ vs 2.9 ± 0.6 s⁻¹, correspondingly; P = 0.009) and regarding LA strain and strain rate during the conduit phase (9.7 [7.1–12.5]% vs 12.9 [9.4–15.1]% vs 11.5 [9.1–13.8]%, correspondingly; P < 0.001 and 2.1 [1.6–2.7] s⁻¹ vs 2.8 [2.4–3.6] s⁻¹ vs 2.6 [2.2–3.0] s⁻¹, respectively; P < 0.001). In addition, LA strain rate during the conduit phase was lower in the moderate-risk score group than the low-risk score group. After adjustments for possible confounders, these differences remained statistically significant. The risk of postoperative AF and prolonged ICU stay was highest in the high-risk score group (relative risk = 9.67 (1.31–71.43) and 8.05 (1.08–60.16), respectively; P = 0.026 and P = 0.042, respectively).

Conclusions

LA reservoir and conduit functions decreased in the high-risk score group, which was accompanied by an increased risk of postoperative AF and prolonged ICU stay.

Comparison of the ATRIA, CHA2DS2-VASc, and Modified Scores ATRIA-HSV, CHA2DS2-VASc-HS, for the Prediction of Coronary Artery Disease Severity

Many parameters included in the Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA) and CHA₂DS₂-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, stroke, vascular disease, age 65-74 years, sex category) scores also predict coronary artery disease (CAD). We modified the ATRIA score (ATRIA-HSV) by adding hyperlipidemia, smoking, and vascular disease and also male sex instead of female. We evaluated whether the CHA₂DS₂-VASc, CHA₂DS₂-VASc-HS, ATRIA, and ATRIA-HSV scores predict severe CAD. Consecutive patients with coronary angiography were prospectively included. A ≥50% stenosis in ≥1epicardial coronary artery (CA) was defined as severe CAD. Patient with normal CA (n = 210) were defined as group 1, with <50% CA stenosis (n = 178) as group 2, and with ≥50% stenosis (n = 297) as group 3. The mean ATRIA, ATRIA-HSV, CHA₂DS₂-VASc, and CHA₂DS₂VASc-HS scores increased from group 1 to group 3. A correlation was found between the Synergy between PCI with Taxus and Cardiac Surgery score and ATRIA (r = 0.570), ATRIA-HSV (r = 0.614), CHA₂DS₂-VASc (r = 0.428), and CHA₂DS₂-VASc-HS (r = 0.500) scores (Ps < .005). Pairwise comparisons of receiver operating characteristics curves showed that ATRIA-HSV (>3 area under curve [AUC]: 0.874) and ATRIA (>3, AUC: 0.854) have a better performance than CHA₂DS₂-VASc (>1, AUC: 0.746) and CHA₂DS₂-VASc-HS (>2, AUC: 0.769). In conclusion, the ATRIA and ATRIA-HSV scores are simple and may be useful to predict severe CAD.

Secondary prevention of coronary artery disease in Poland. Results from the POLASPIRE survey

BACKGROUND

The highest priority in preventive cardiology is given to patients with established coronary artery disease (CAD). The aim of the study was to assess the current implementation of the guidelines for secondary prevention in everyday clinical practice by evaluating control of the main risk factors and the cardioprotective medication prescription rates in patients following hospitalization for CAD.

METHODS

Fourteen departments of cardiology participated in the study. Patients (aged ≤ 80 years) hospitalized due an acute coronary syndrome or for a myocardial revascularization procedure were recruited and interviewed 6-18 months after the hospitalization.

RESULTS

Overall, 947 patients were examined 6-18 months after hospitalization. The proportion of patients with high blood pressure (≥ 140/90 mmHg) was 42%, with high low-density lipoprotein cholesterol (LDL-C ≥ 1.8 mmol/L) 62%, and with high fasting glucose (≥ 7.0 mmol/L) 22%, 17% of participants were smokers and 42% were obese. The proportion of patients taking an antiplatelet agent 6-18 months after hospitalization was 93%, beta-blocker 89%, angiotensin converting enzyme inhibitor or sartan 86%, and a lipid-lowering drug 90%. Only 2.3% patients had controlled all the five main risk factors well (non-smoking, blood pressure < 140/90 mmHg, LDL-C < 1.8 mmol/L and glucose < 7.0 mmol/L, body mass index < 25 kg/m2), while 17.9% had 1 out of 5, 40.9% had 2 out of 5, and 29% had 3 out of 5 risk factors uncontrolled.

CONCLUSIONS

The documented multicenter survey provides evidence that there is considerable potential for further reductions of cardiovascular risk in CAD patients in Poland. A revision of the state funded cardiac prevention programs seems rational.

Association of circular RNAs and environmental risk factors with coronary heart disease

Background

Coronary heart disease (CHD) is a complex disease caused by multi-factors and a major threat to human health. Circular RNAs (circRNAs) have critical roles in various biological processes and diseases. This study explores the independent role of circRNAs and their interaction with environmental factors in CHD.

Methods

A case–control study was conducted from March 2015 to September 2017 in Fuzhou, China. A total of 585 CHD patients and 585 gender- and age-matched healthy controls were enrolled. Questionnaire survey, health examination and molecular biology laboratory testing were conducted. Microarray technology and quantitative real-time polymerase chain reaction (PCR) were used to profile the expression levels of circRNAs. The area under the curve (AUC) of the receiver operating characteristic (ROC) was used to determine the diagnostic cut-offs. Multivariate logistic regression and multiplicative analysis were used to analyse the effects of environmental factors and hsa_circ_0008507, hsa_circ_0001946, hsa_circ_0000284 and hsa_circ_0125589 on CHD.

Results

The expression profile of circRNAs showed that 3423 circRNAs were differentially expressed at P < 0.05, but none pass multiple testing correction. qRT-PCR further confirmed the expression levels of hsa_circ_0008507, hsa_circ_0001946 and hsa_circ_0000284 in peripheral blood leukocytes in CHD cases were higher than those in non-CHD subjects (All p < 0.05). Hsa_circ_0008507 (OR = 1.29; 95% CI: 1.11–1.50), hsa_circ_0001946 (OR = 1.20; 95% CI: 1.01–1.42) and hsa_circ_0000284 (OR = 2.05; 95% CI: 1.32–3.19) were independent risk factors for CHD after controlling other common environmental risk factors. The AUC for hsa_circ_0008507, hsa_circ_0001946 and hsa_circ_0000284 was 0.75, 0.71 and 0.68, respectively. Compared with non-smoking individuals with low hsa_circ_0008507 expression, the smokers with high hsa_circ_0008507 expression showed the highest magnitude of OR in CHD risk. Additionally, a statistically significant multiplicative interaction was found between hsa_circ_0008507 and smoking for CHD.

Conclusions

Hsa_circ_0008507, hsa_circ_0001946 and hsa_circ_0000284 were closely related to the occurrence and development of CHD. The combination of smoking and high hsa_circ_0008507 expression causes the occurrence and development of CHD.

Demographics of patients with heart failure who were over 80 years old and were admitted to the cardiology clinics in Turkey

Objective:

Heart failure (HF) has a high prevalence and mortality rate in elderly patients; however, there are few studies that have focused on patients older than 80 years. The aim of this study is to describe and compare the age-specific demographics and clinical features of Turkish elderly patients with HF who were admitted to cardiology clinics.

Methods:

The Epidemiology of Cardiovascular Disease in Elderly Turkish population (ELDER-TURK) study was conducted in 73 centers in Turkey, and it recruited a total of 5694 patients aged 65 years or older. In this study, the clinical profile of the patients who were aged 80 years or older and those between 65 and 79 years with HF were described and compared based on the ejection fraction (EF)-related classification: HFrEF and HFpEF (is considered as EF: ≥50%).

Results:

A total of 1098 patients (male, 47.5%; mean age, 83.5±3.1 years) aged ≥80 years and 4596 patients (male, 50.2 %; mean age, 71.1±4.31 years) aged 65-79 years were enrolled in this study. The prevalence of HF was 39.8% for patients who were ≥80 years and 27.1% for patients 65–79 years old. For patients aged ≥80 years with HF, the prevalence rate was 67% for hypertension (HT), 25.6% for diabetes mellitus (DM), 54.3% for coronary artery disease (CAD), and 42.3% for atrial fibrilation. Female proportion was lower in the HFrEF group (p=0.019). The prevalence of HT and DM was higher in the HFpEF group (p<0.01), whereas CAD had a higher prevalence in the HFrEF group (p=0.02). Among patients aged 65–79 years, 43.9% (548) had HFpEF, and 56.1% (700) had HFrEF. In this group of patients aged 65-79 years with HFrEF, the prevalence of DM was significantly higher than in patients aged ≥80 years with HFrEF (p<0.01).

Conclusion:

HF is common in elderly Turkish population, and its frequency increases significantly with age. Females, diabetics, and hypertensives are more likely to have HFpEF, whereas CAD patients are more likely to have HFrEF.
