Inaccurate risk perceptions contribute to treatment gaps in secondary prevention of cardiovascular disease

The impact of perception bias for cardiovascular disease risk on physical activity and dietary habits

Objective

Cardiovascular disease (CVD) remains a significant public health challenge in China. Accurate perception of individual CVD risk is crucial for timely intervention and preventive strategies. This study aimed to determine the alignment between CVD risk perception levels and objectively calculated CVD risk levels, then investigate the disparity in physical activity and healthy diet habits among distinct CVD risk perception categories.

Methods

From March to August 2022, a cross-sectional survey was conducted in Zhejiang Province using convenience sampling. Participants aged between 20 and 80 years, without prior diagnosis of CVD were included. CVD risk perception was evaluated with the Chinese version of the Attitude and Beliefs about Cardiovascular Disease Risk Perception Questionnaire, while objective CVD risk was assessed through the Prediction for Atherosclerotic Cardiovascular Disease Risk (China-PAR) model. Participants' demographic information, self-reported physical activity, and healthy diet score were also collected.

Results

A total of 739 participants were included in the final analysis. Less than a third of participants (29.2%) accurately perceived their CVD risk, while 64.5% over-perceived it and 6.2% under-perceived it. Notably, half of the individuals (50.0%) with high CVD risk under-perceived their actual risk. Compared to the accurate perception group, individuals aged 60-80 years old (OR = 6.569), currently drinking (OR = 3.059), and with hypertension (OR = 2.352) were more likely to under-perceive their CVD risk. Meanwhile, participants aged 40-<60 years old (OR = 2.462) and employed (OR = 2.352) were more likely to over-perceive their risk. The proportion of individuals engaging in physical activity was lowest in the under-perception group, although the difference among the three groups was not statistically significant (χ 2 = 2.556, P = 0.278). In addition, the proportion of individuals practicing healthy diet habits was also lowest in the under-perception group, and a significant statistical difference was observed among the three groups (χ 2 = 10.310, P = 0.006).

Conclusion

Only a small proportion of participants accurately perceived their CVD risk, especially among those with high actual CVD risk. Individuals in the under-perceived CVD risk group exhibited the lowest rates of physical activity engagement and healthy diet adherence. Healthcare professionals should prioritize implementing personalized CVD risk communication strategies tailored to specific subgroups to enhance the accuracy of risk perception.

Ethical Considerations of Declining Surgical Intervention: Balancing Patient Wishes with Fiduciary Responsibility

ABSTRACT

Orthopaedic surgeons face increasing pressure to meet quality metrics due to regulatory changes and payment policies. Poor outcomes, including patient mortality, can result in financial penalties and negative ratings. Importantly, adverse outcomes often increase surgeon stress level and lead to job dissatisfaction and burnout. Despite optimization efforts, some orthopaedic patients remain at high risk for complications. In this article, we explore the ethical considerations when surgeons are presented with high-risk surgical candidates. We examine how the ethical tenets of patient interests, namely beneficence, nonmaleficence, autonomy, and justice, apply to such patients. We discuss external forces such as the malpractice environment, financial challenges in health-care delivery, and quality rankings. Informed consent and the challenges of communicating risks to patients are discussed, as well as the role of modifiable and nonmodifiable risk factors. Case examples with varied outcomes highlight the complexities of decision-making with high-risk patients and the potential role of palliative care. We provide recommendations for surgeons and care teams, including the importance of justifiable reasons for not operating, the utilization of institutional resources to help make care decisions, and the robust communication of risks to patients.

Recurrence Risk Perception, Fear of Progression, and Health Behaviors Among Patients With Ischemic Stroke

BACKGROUND

The relationship between recurrence risk perception, fear of progression, and health behaviors in patients with ischemic stroke is unclear.

OBJECTIVE

To explore the effect of accuracy and level of recurrence risk perception on health behaviors and the mediating role of fear of progression.

METHODS

We conducted a 2-wave survey. Patients with ischemic stroke (N = 261) were recruited from 2 hospitals in Guangzhou, China. Before discharge, demographic information, objective recurrence risk, perceived recurrence risk, fear of progression, and health behaviors were investigated. After 1 month, the patient's health behaviors were followed up.

RESULTS

The median (quartiles 1-3) scores for recurrence risk perception and fear of progression were 43.0 (39.0-46.0) and 22.0 (18.0-28.0), respectively. Only 22.2% of the patients correctly perceived the risk of recurrence, 23.0% underestimated the risk, and 30.7% overestimated the risk. Patients who overestimated the risk of recurrence (β = 0.421, P = .002) or had a higher perceived level of recurrence risk (β = 0.446, P < .001) had a higher fear of progression, which contributed to better health behaviors at 1 month (β = 0.197, P = .001). Fear of progression played a partial and full mediating role, respectively. Patients who underestimated the recurrence risk had worse health behaviors than those who accurately perceived it (β = -0.296, P = .033).

CONCLUSION

Both accuracy and level of recurrence risk perception were independent predictors of future health behaviors, and fear of progression was mediating. Health care professionals should develop individualized risk education programs to help stroke patients properly understand and cope with the risk of recurrence.

Is an accurate self-perceived health risk beneficial for patients to minimize prehospital delay time at onset of a ST-segment elevated myocardial infarction (STEMI)?

High risk perception (HRP) is fundamental for adequate health behavior. However, its impact on rapid access to cardiac care after the onset of acute myocardial infarction (AMI) is not known. Conflicting evidence exists about sources that promote HRP. Data on sociodemographic and clinical characteristics of 588 AMI patients who participated in the Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study were collected at the bedside. Adjusted multivariate logistic regression models identified factors associated with HRP. Only 13.4% (n = 79) of patients had a favorable HRP level. The HRP patients did not differ from those with low risk perception (LRP) in terms of sex, age, other sociodemographic features, and somatic risk factors. Among the univariate contributors to HRP were prodromal chest pain (p = 0.0004), symptom mismatch during AMI (p < 0.0001), depression (p = 0.01), and anxiety (p = 0.005). However, family history of AMI, a previous AMI, and knowledge of AMI remained significant in the multivariate regression model. Median delay time to reach a hospital-based emergency facility after the onset of AMI was 127 min (interquartile range [IQR]: 83-43, p = 0.02) in HRP patients and 216 min (IQR: 106-721) in LRP patients. An increasing risk perception score was associated with a corresponding stepwise decline in median delay time (p > 0.004). Self-perceived AMI risk is associated in a dose-response relationship with the time needed to reach coronary care emergency facilities. Recurrent AMI, family history of AMI, and sufficient knowledge of MI contribute to risk perception, whereas somatic risk factors do not.

Patients' preferences for secondary prevention following a coronary event

Objective

Despite clear evidence on the effectiveness of secondary prevention, patients with coronary artery disease frequently fail to reach guideline-based risk factor targets. Integrating patients' preferences into treatment decisions has been recommended to reduce this gap. However, this requires knowledge about patient treatment preferences. Therefore, through a survey study, we aimed to explore which risk factors patients self-perceived, prioritised for improvement, and needed support with after a recent hospitalisation for coronary heart disease.

Methods

A digital questionnaire was presented to patients > 18 years recently discharged (≤3 months) from an acute coronary care unit in the Netherlands (Europe). Patients could select from eight cardiovascular risk factors that they (1) self-perceived, (2) prioritised for improvement, and (3) needed support to improve. Patients' perceived risk factors were compared to those documented in the medical records.

Results

Respondents (N = 254, 26 % women), mean age 64 (SD 10) years, identified 'physical inactivity' more frequently than their medical records (140 patients vs. 91 records, p < 0.001), while three other risk factors were reported with equal and four with lower frequency. 'Physical inactivity', 'overweight' and 'stress' were most frequently prioritised for improvement (82 %, 88 % and 78 %) and professional support (64 %, 50 % and 58 %), with 87 % preferring lifestyle optimisation if this would reduce drug use.

Conclusions

Patients with a recent coronary event show significant disparities in identifying risk factors compared to their medical records. They tend to prefer improving lifestyle- over drug-modifiable risk factors, particularly physical inactivity, overweight and stress, and indicate the need for support in improving these factors.

Mediation role of perceived social support between recurrence risk perception and health behaviour among patients with stroke in China: a cross-sectional study

OBJECTIVES

To examine whether patients who had a stroke with high recurrence risk perception would have healthier behaviour and to explore whether perceived social support would function as a mediator.

DESIGN

A cross-sectional study.

SETTING

The study was conducted in a public tertiary hospital in China.

PARTICIPANTS

A total of 254 patients with stroke were invited to participate, and 250 patients with stroke completed questionnaires validly.

PRIMARY AND SECONDARY OUTCOME MEASURES

Questionnaires were administered offline to collect data, consisting of four parts: general demographics and scales related to recurrence risk perception, perceived social support, and health behaviour. A path analysis and correlation analysis were used to analyse the data.

RESULTS

Out of 250 patients with stroke, 78.4% had moderately low health behaviour. The majority (70.8%) of these patients were elderly. High recurrence risk perception and high perceived social support were significantly associated with better health behaviour (all p<0.001). Perceived social support mediated the relationship between recurrence risk perception and health behaviour after controlling for age, gender, education and monthly income in the regression model (95% CI 0.263 to 0.460) and the effect value was 0.360. It was also confirmed that perceived social support had the highest mediation effect with a proportion of mediation up to 59.31%.

CONCLUSIONS

Recurrence risk perception and perceived social support were influential factors in promoting health behaviour. Moreover, the impact of recurrence risk perception on health behaviour was partially mediated by perceived social support. Therefore, to enhance the sustainability of health behaviour, it is crucial to inform patients with stroke about the risk of recurrence. Patients with more perception of recurrence risk can improve their recovery confidence and thus perceive more social support.

Does a multi-component intervention including pictorial risk communication about subclinical atherosclerosis improve perceptions of cardiovascular disease risk without deteriorating efficacy beliefs?

BACKGROUND

Pictorial communication about subclinical atherosclerosis can improve cardiovascular disease (CVD) risk, but whether it leads to long-term shifts in self-rated CVD risk (risk perception) and beliefs about possibility to influence personal risk (efficacy beliefs) is unknown.

PURPOSE

To study the impact of personalized color-coded and age-related risk communication about atherosclerosis and motivational conversation, compared to traditional risk factor-based communication, on risk perception and efficacy beliefs. Also, whether risk perception increases with message severity.

METHOD

The effect of the pragmatic RCT Visualization of Asymptomatic Atherosclerotic Disease for Optimum Cardiovascular Prevention (VIPVIZA) was analyzed using a linear mixed effects model with risk perception and efficacy believes at 1-year and 3-year follow up as dependent variables. Participants' (n = 3532) CVD risk perception and efficacy beliefs were assessed with visual analog scales (0-10). Fixed effects were group (intervention vs control), time point (1 year or 3 years) and interaction between group and time point. Further, the models were adjusted for corresponding baseline measurement of the dependent variable and a baseline × time point interaction. Effect of pictorial color-coded risk in the intervention group was investigated using a corresponding mixed effects model, but with pictorial risk group (message severity) as exposure instead of intervention group.

RESULTS

After one year, the intervention group rated their CVD risk as higher (m = 0.46, 95% CI 0.32-0.59), with an effect also after 3 years (m = 0.57, 95% CI 0.43-0.70). The effect was consistent in stratified analyses by sex and education. Overall, no effect on efficacy beliefs was observed. In the intervention group, differences in CVD risk perception were found between participants with different color-coded risk messages on atherosclerosis status.

CONCLUSION

Personalized, color-coded and age-related risk communication about atherosclerosis had an effect on risk perception with an effect also after 3 years, whereas overall, no effect on efficacy beliefs was observed.

Community-Dwelling Adults' Perceived Versus Actual Risk of Cardiovascular Disease, Body Mass Index, and Physical Activity Levels and Related Factors

CONTEXT

The difference between actual and perceived risk levels shows distorted risk perception. Unrealistic perceptions of cardiovascular disease (CVD) risks and insufficient knowledge about CVD risk factors can not only hinder the adoption of a positive lifestyle change but also obstruct preventive efforts.

OBJECTIVE

The aim of this study was to evaluate the concordance between perceived and actual risks, body mass index (BMI), and physical activity levels.

DESIGN

This descriptive study included 522 community-dwelling adults in 2 different regions of Antalya/Turkey. The actual CVD risk level of the participants was determined using the "HeartScore program," actual body weight was determined according to BMI, and actual activity levels were found using the "International Physical Activity Questionnaire Short Form (IPAQ-SF)." The perceived risks were measured with the CVD Risk and Risk Factors Perception Determination Questionnaire. CVD Risk Factors Knowledge Level (CARRF-KL) Scale was used to calculate the participants' level of knowledge about the risk factors.

RESULTS

There was no concordance between the participants' actual and perceived CVD risks. A below-average agreement was found between the participants' actual and perceived BMI levels. In terms of actual measurements, it was seen that slightly obese individuals have a realistic perception. There was a weak agreement between the actual and perceived physical activity levels of the adults. Knowledge about the CVD risk factors of adults does not affect the perception of CVD risk and BMI and physical activity.

CONCLUSIONS

Adults have an optimistic risk perception regarding CVD risk, BMI, and physical activity levels. It may be beneficial to periodically assess actual risks to change skewed perceptions of CVD and risk factors. These findings will inform the development of tailored intervention strategies and policies for these adults.

The Benefits of a Comprehensive Cardiac Rehabilitation Program for Patients with Acute Coronary Syndrome: A Follow-Up Study

BACKGROUND AND OBJECTIVES

Secondary prevention after acute coronary syndrome (ACS) is essential to reduce cardiovascular mortality and hospital readmission, ensuring patients return to normal with an improved quality of life. Thus, we investigate the benefits of a comprehensive cardiac rehabilitation (CR) program on lifestyle, risk factors and adherence to guideline-directed medical therapy (GDMT) in patients after ACS and myocardial revascularization through coronary artery by-pass grafting (CABG) or percutaneous coronary intervention (PCI).

METHODS

This is a prospective, longitudinal study in consecutive post-CABG or PCI patients after ACS that participated or not in a comprehensive CR. Cardiovascular risk factors, quality of life and adherence to GDMT were analyzed in terms of assessing the benefit of 12 months of comprehensive CR on reaching guidelines secondary prevention targets.

RESULTS

At the inclusion in comprehensive CR of all patients (n = 480), 85% had hypertension; 86% had elevated total cholesterol values; 69% were characterized by metabolic syndrome; 43% were obese; 31% were active smokers and 29% had type 2 diabetes mellitus. Only 26.66% (n = 128) followed the entire program for 12 months. No statistically significant differences in the prescription of GDMT at hospital discharge after myocardial revascularization between the CR (+) group (n = 128) versus CR (-) group (n = 352) (p > 0.05) were observed. After 12 moths, a significant adherence to GDMT in the CR (+) group vs. CR (-) group was recorded, as follows: antiplatelet agents (100% versus 96%, p = 0.001), beta-blockers (99% versus 92%, p = 0.02), ACE inhibitors/ARAB (89% versus 79%, p = 0.04), lipid-lowering drugs (100% versus 89%, p = 0.001). In total, 82% of the CR (+) patients had a significantly higher adherence at GDMT (82% versus 64%, p = 0.001). At 12 moths, the CR (+) group was characterized by significantly lower values than at the inclusion but some values still increased: systolic blood pressure (139.25 + 19.20 mmHg (p < 0.03)), total cholesterol (171.07 + 48.59 mg/dL (p = 0.0001)) and LDL-cholesterol (102.83 + 41.30 mg/dL (p = 0.009)). At the same time, the analysis of psychosocial factors using the HAD questionnaire revealed a statistically significant improvement in anxiety and depression scores: HAD-A score (9.1 ± 3.7 at T0 vs. 7.1 ± 4.2 at T1, p = 0.001) and HAD-D score (7.7 ± 3.19 at T0 vs. 6.4 ± 4.3 at T1, p = 0.003). A multivariable analysis, following GDMT, showed the actual value or information and training of patients regarding optimal cardiovascular risk factor control was independently associated with lower values of systolic blood pressure (R2 = 0.48), diastolic (R2 = 0.38), serum glucose (R2 = 0.48), glycated hemoglobin (R2 = 0.50), total cholesterol (R2 = 0.31), LDL-cholesterol (R2 = 0.30), HDL-cholesterol (R2 = 0.19) and serum triglycerides (R2 = 0.20).

CONCLUSION

The twelve-month participation of post-ACS patients in comprehensive CR resulted in excellent post-revascularization management, as well as good adherence to guideline-directed medical therapy, provided further confirmation of the benefit of secondary prevention. Despite high adherence to drug treatments, targets for blood pressure, total cholesterol and LDL-cholesterol are inadequately achieved. Therefore, in the era of personalized medicine, patients with ACS should benefit from specific, comprehensive cardiovascular recovery programs that contain physiotherapists, psychologists, nutritionists and an experienced cardiologist in cardiovascular rehabilitation.

Associations among risk perception, health efficacy, and health behaviors for cardiovascular disease: an application of risk perception attitude framework

Background

There is currently a pervasive prevalence of cardiovascular disease (CVD) risk worldwide and an inadequate amount of action is being taken to promote healthy lifestyle habits. The risk perception attitude (RPA) framework, which classifies individuals based on their risk perception and efficacy belief, enables us to predict their preventive behaviors. We applied the RPA framework to analyze CVD prevention behaviors among Chinese adults and extended its application to CVD objective risk.

Methods

A cross-sectional survey was performed in two sites in Zhejiang Province, from March to August 2022, which contained self-reported CVD risk perception, objective CVD risk, efficacy belief, physical activity, healthy diet, and covariates. We used the RPA framework to categorize participants into four groups, then analysis was conducted to estimate inter-group differences in healthy behaviors. We further conducted a hierarchical logistic regression analysis with individuals' health behaviors as the dependent variable, using three blocks of independent variables.

Results

Among 739 participants, healthy physical activity and healthy diet had significant differences among four RPA groups, post hoc tests clarified that the proportion of respondents with healthy PA in the responsive group (61.6%) was significantly higher than that in the other three groups. Risk perception and efficacy belief significantly predicted health behavior against CVD; the relationship between absolute CVD risk and health behavior was moderated by efficacy belief.

Conclusions

Early CVD risk screening is crucial, but tailored support and a proper understanding of personal risk are essential to promote healthy behaviors. Developing communication and behavioral counseling intervention strategies on the basis of the RPA framework has the potential to promote healthy behaviors for CVD prevention.

Cardiovascular disease risk perception among community adults in South China: a latent profile analysis

Objective

Risk perception, a critical psychological construct, influences health behavior modification and maintenance of individuals with cardiovascular disease (CVD) risk. Little is known about CVD risk perception among Chinese adults. This research examined the profiles of CVD risk perception of community adults in South China, and explored the characteristics and factors that influence their perception of CVD risk.

Method

This cross-sectional study was conducted in Hangzhou, Zhejiang Province, in South China from March to July 2022 and included 692 participants. Risk perception was assessed using the Chinese version of the Attitude and Beliefs about Cardiovascular Disease Risk Questionnaire. Latent profile analysis (LPA) was performed to extract latent classes of CVD risk perception. These classes of CVD risk perception were compared with 10-year CVD risk categories to define correctness of estimation. Chi-square tests and multinomial regression analyses were used to identify differences between these categories.

Results

Three CVD risk perception classes were identified by LPA: low risk perception (14.2% of participants), moderate risk perception (46.8%), high risk perception (39.0%). Individuals who were aged with 40-60 year (OR = 6.94, 95% CI = 1.86-25.84), diabetes (OR = 6.26, 95% CI = 1.34-29.17), married (OR = 4.52, 95% CI = 2.30-8.90), better subjective health status (OR = 3.23, 95% CI = 1.15-9.10) and perceived benefits and intention to change physical activity (OR = 1.16, 95% CI = 1.05-1.27) were more likely to be in the high-risk perception class. Compared to absolute 10-year CVD risk based on China-PAR, a third of participants (30.1%) correctly estimated their CVD risk, 63.3% overestimated it and 6.6% underestimated it. CVD risk underestimation was associated with hypertension (OR = 3.91, 95% CI = 1.79-8.54), drinking (OR = 3.05, 95% CI = 1.22-7.64), better subjective health status (OR = 2.67, 95% CI = 1.18-6.03).

Conclusions

Most adults in South China possess a moderate level of CVD risk perception. Advanced age, higher monthly income, diabetes and better health status were significantly related to higher perceived CVD risk. Individuals with hypertension, drinking and better subjective health status were associated with CVD risk underestimation. Healthcare professionals should pay attention to the indicators for different classes and identify underestimation group as early as possible.

Psychometric properties of the Chinese version of Attitudes and Beliefs about Cardiovascular Disease Risk Perception Questionnaire

Cardiovascular disease (CVD) is the leading cause of global mortality and disease burden. The perceived risk of CVD, a central psychological construct, may affect health behavior change and maintenance, such as lifestyle modification and medication adherence. Risk perception varies based on the knowledge of risk in the context of cultural health-world views. Little is known about CVD-related knowledge and risk perception in China. The aim of this study is to cross-culturally translate, adapt, and evaluate the psychometric properties of the Attitudes and Beliefs about Cardiovascular Disease (ABCD) Risk Perception Questionnaire in Chinese. The translation and cross-cultural adaptation process followed established guidelines. A cross-sectional study of 318 adults between April and May 2022 was conducted in Zhejiang province. The study evaluated the item- and scale-level psychometric properties and validity indices of the ABCD risk perception questionnaire. The exploratory and confirmatory factor analyses of the risk scale supported a three-factor solution that accounts for 69.63% of the total variance, corresponding to risk perception (F1), perceived benefits and intention to change physical activity (F2), and perceived benefits and intention to change dietary habits (F3). Adequate content validity (I-CVI = 0.852-1.00, S-CVI = 946) was ensured by expert panel. The internal consistency of the dimensions showed good results ranging from 0.801 to 0.940 for Cronbach's α, and 0.853 to 0.952 for McDonald's ω. The item analysis of knowledge dimension indicated that the item difficulty index was 0.440 to 0.852, the item discrimination index was 0.572 to 0.707. This study confirmed that the Chinese version of the ABCD risk perception questionnaire has good psychometric properties in terms of measuring CVD-related knowledge and risk perception in the Chinese adult population, which can lead to the development of individually tailored CVD-risk reduction intervention programs or risk communication programs by health providers.

Low Subjective Cardiovascular Disease Risk Perceptions among Hypertensive Patients in Addis Ababa, Ethiopia

Background

Accurate cardiovascular disease (CVD) risk appraisal is essential for hypertensive patients to identify correctly their risk status and take efficient behavioral measures timely to avoid major adverse outcomes. However, hypertensive patients’ risk perceptions of CVD events in Ethiopia are unknown. Thus, the study aimed to compare the subjective CVD risk perception level of patients with the nonlaboratory Framingham Risk Score (nl-FRS).

Methods

A cross-sectional design was used. The Attitudes and Beliefs about Cardiovascular Disease Risk Questionnaire and the nl-FRS were used to compare subjective versus objective measures of CVD risk. Agreement between participants’ risk perceptions and the nl-FRS were examined using the kappa statistic. Bivariate chi-square test and multinomial logistic regression analyses were run to identify factors associated with risk perceptions. The statistical significance was set at a p-value < 0.05 level.

Results

Participants (n=377) had a mean age of 53.61 ± 12.80-years, range (18–82 years), 51.2% were males, 42.7% had less than high school education, 45.1% achieved target BP control, and mean HTN duration was 8.01 ± 6.07 years. The majority (58.62%) of the participants had a low subjective risk perception of CVD events (mean 17.79, 95% CI: 17.43–18.15). Approximately three-fourths (72.4%) had a moderate nl-FRS risk calculation (mean, 13.84, 95% CI: 13.36–14.33). Agreement between participants perceived-risk and the nl-FRS was poor (kappa = 0.0002, standard error = 0.023, p =0.99). Participants’ CVD risk-perception inaccuracy was also high (76%) primarily due to underestimation. Hypertension duration, frequency of physician visits, and level of diabetes control were significant predictors of CVD risk underestimation.

Conclusion

Hypertensive patients had inaccurate and low subjective risk perceptions of CVD events compared to moderate objective risks identified using the nl-FRS. Planned education on HTN and CVD risk factors is essential to improve patients’ CVD risk perception to reduce adverse CVD events.

Increasing Perceived Risk of Opioid Misuse: The Effects of Concrete Language and Image

Risk perception is a critical determinant for individuals' health behavior change, especially for behaviors with distal future consequences. Building on construal-level theory, this study investigates if and how thinking concretely about the negative consequences of opioid misuse influences people's risk perception toward opioid misuse. Two message cues - images and concrete (vs. abstract) language - are proposed to influence concrete thinking and perceived temporal distance, which in turn influence risk perception directly and through negative affect. Using a factorial online experiment with Amazon Mechanical Turk workers (N = 220), this study found that messages using concrete language made people think more concretely about the negative consequences of opioid misuse. Perceived concreteness, in turn, increased risk perception and negative affect. Negative affect also increased risk perception. The use of images decreased perceived temporal distance, which in turn, changed risk perception through its influence on negative affect. Theoretical and practical implications are discussed.

What CVD risk factors predict self-perceived risk of having a myocardial infarction? A cross-sectional study

Background

This study aims to identify predictors of self-perceived risk of myocardial infarction (MI).

Methods

Among 564 men and women (50–65 years; randomly selected from the Swedish population), we assessed risk perception as relative self-perceived risk compared to others (lower, same, higher) and percentage ten-year absolute risk. Predictors (added blockwise) were identified using multinomial or linear regression, providing odds ratios (ORs) or β coefficients with their 95% confidence intervals (CI).

Results

The mean of self-perceived 10-year MI risk was 12%. Lower BMI (AOR 0.57, 95% CI: 0.44–0.75), low stress (AOR 2.51, 95% CI: 1.39–4.52), high level of physical activity (AOR 1.66, 95% CI:1.01–2.74), hypertension (AOR 0.42, 95% CI: 0.23–0.76), family history (AOR 0.38, 95% CI: 0.21–0.69), and poor general health (AOR 0.41, 95% CI: 0.19–0.89) predicted if respondents perceived their MI risk as lower. Poor general health (AOR 1.94, 95% CI: 1.01–3.73), family history (AOR 2.72, 95% CI: 1.57–4.72), and high cholesterol (AOR 2.45, 95% CI: 1.18–5.09) predicted if respondents perceived their MI risk as higher. Low level of self-perceived CVD knowledge and low numeracy predicted if respondents perceived their MI risk as the same as others. High cholesterol (B 6.85, 95% CI: 2.47–11.32) and poor general health (B 8.75, 95% CI: 4.58–13.00) predicted a higher percentage of perceived ten-year risk.

Conclusion

General health was a common predictor of self-perceived MI risk. Lifestyle factors (BMI, physical activity) and stress dominated the predictors for perceiving MI risk as lower than others, while high cholesterol predicted perception of high risk.

Gender and Social Inequalities in Awareness of Coronary Artery Disease in European Countries

Coronary artery disease (CAD) is the single leading cause of death in Europe and the most common form of cardiovascular disease. Little is known about awareness in the European population. A cross-sectional telephone survey of 2609 individuals from six European countries was conducted to gather information on perceptions of CAD, risk factors, preventive measures, knowledge of heart attack symptoms and ability to seek emergency medical care. Level of awareness was compared according to gender, age, socioeconomic status (SES) and educational level. Women were approximately five times less likely than men to consider heart disease as a main health issue or leading cause of death (OR = 0.224, 95% CI: 0.178–0.280, OR = 0.196, 95% CI: 0.171–0.226). Additionally, women were significantly less likely to have ever had a cardiovascular screening test (OR = 0.515, 95% CI: 0.459–0.578). Only 16.3% of men and 15.3% of women were able to spontaneously identify the main symptoms of a heart attack. Almost half of the sample failed to state that they would call emergency services in case of a cardiac event. Significant differences according to age, SES and education were found for many indicators amongst both men and women. Development of a European strategy targeting improved awareness of CAD and reduced gender and social inequalities within the European population is warranted.

Good general health and lack of family history influence the underestimation of cardiovascular risk: a cross-sectional study

AIMS 

Underestimation of cardiovascular risk may interfere with prevention of cardiovascular diseases (CVDs). We investigate whether general health and family history of myocardial infarction (MI) are associated with underestimation of perceived cardiovascular risk, and if the participants' calculated risk modifies that association.

METHODS AND RESULTS 

The analysis sample consisted of 526 individuals, 50-64 years old, from a population-based cohort study. Information on general health (poor/fairly good, good, and very good/excellent), family history of MI, and self-perceived risk relative to others of similar age and sex were collected though a web-based survey. Participants were categorized into underestimation (n = 162, 31%), accurate estimation (n = 222, 42%), and overestimation (n = 142, 27%) of cardiovascular risk by comparing calculated Systematic Coronary Risk Estimation (SCORE) with self-perceived risk. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for underestimation vs. accurate estimation of cardiovascular risk were computed using logistic regression (n = 384). Very good general health (OR 2.60, 95% CI 1.10-6.16) and lack of family history (OR 2.27, 95% CI 1.24-4.18) were associated with underestimation of cardiovascular risk. The associations were modified by the participants' calculated risk level; the association was stronger for high-risk individuals; without family history OR 22.57 (95% CI 6.17-82.54); with very good/excellent health OR 15.78 (95% CI 3.73-66.87).

CONCLUSION 

A good general health and the lack of family CVD history can obscure the presence of other risk factors and lead to underestimation of cardiovascular risk, especially for high-risk individuals. It is, therefore, crucial to address the fact that the development of CV disease may be silent and multifactorial.

Impact of a coronary artery calcium-guided statin treatment protocol on cardiovascular risk at 12 months: Results from a pragmatic, randomised controlled trial

BACKGROUND AND AIMS

Coronary artery calcium (CAC) may encourage patients to adhere to primary prevention recommendations. This study sought to evaluate the benefit of a CAC-guided risk-management protocol in those with a family history of premature coronary artery disease (FHCAD).

METHODS

In this Australian multi-centre, randomized controlled trial (Coronary Artery Calcium score: Use to Guide management of Hereditary Coronary Artery Disease, CAUGHT-CAD), asymptomatic, statin-native participants at low-intermediate cardiovascular risk with FHCAD underwent CAC assessment. Those with CAC between 1 and 400 were randomized (1:1) to disclosing the CAC result to both patient and physician and commencing atorvastatin (intervention) or blinding the CAC result with risk factor education only (control). The primary endpoint of this sub-study was change in Pooled Cohort Equation (PCE) at 12 months.

RESULTS

Of 1088 participants who were scanned, 450 were randomised and 214 in both groups completed 1-year follow-up. At 1 year, PCE-risk decreased by 1.0% (95% CI 0.13 to 1.81) in the CAC-disclosed group and increased by 0.43% (95%CI 0.11-0.75) in the CAC-blinded group. LDL-C decreased in the CAC-disclosed group in both those who continued (1.5 mmol/L; 95% CI 1.36 to 1.74) and discontinued statins (0.62 mmol/L; 95% CI 0.32 to 0.92) but was unchanged in the CAC-blinded group.

CONCLUSION

Participants unblinded to their CAC showed reductions in LDL irrespective of statin continuation when compared to controls at 12 months. Improvements in individual risk factors and PCE risk were also noted. CAC assessment may positively influence patients and physicians to improve risk factor control.

"Would You Rather Jump Out of a Perfectly Good Airplane or Develop Cardiovascular Disease?" Validity and Reliability of the Cardiovascular Risk Perception Survey Among Military Personnel

BACKGROUND AND PURPOSE

Cardiovascular disease (CVD) is a major cause of death in the United States. The military are viewed as fit, ready to fight and that jumping out of perfectly good airplane or going to war is a greater risk than CVD. The purpose of this study was to determine reliability and validity of the Cardiovascular Risk Perception Survey (CRPS).

METHODS

A cross-sectional descriptive design was performed, supported by the Health Belief Model. Internal consistency reliability (Cronbach's alpha) and validity (principal component analysis) were examined.

RESULTS

Fifty-five participants were included in this study. Construct validity of the CRPS was supported by principal component analysis; indicating one scale that measured cardiovascular risk perception. The Cronbach's alpha is reported .865.

CONCLUSION

Initial psychometric testing of the CRPS provides evidence for construct validity and internal consistency reliability.

Comparisons of Stroke Knowledge and Health Behaviors in Patients With Hypertensive Stroke at Different Recurrence Risk Strata: The Comprehensive Reminder System Based on the Health Belief Model Study

BACKGROUND

Risk factor management via behavioral change contributes substantially to secondary stroke prevention. The health belief model identified self-perceived risk as a significant factor in behavior change. In previous studies, people have tended to incorrectly estimate their risk of stroke. Little is known about the differences in stroke knowledge and health behaviors in patients who have had a stroke with different risks of stroke recurrence in China.

OBJECTIVE

The aims of this study were to determine the accuracy of self-perceived risk of stroke recurrence and to compare stroke knowledge and health behaviors in patients with hypertensive stroke at different recurrence risk strata.

METHODS

Baseline data from 174 patients in the Comprehensive Reminder System based on the Health Belief Model (CRS-HBM) study were used. Self-perceived risk was assessed via the susceptibility subcategory of the Short-Form Health Belief Model Scale, and actual risk was stratified using the Essen Stroke Risk Score.

RESULTS

Only 27.0% of the patients estimated their risks of stroke recurrence accurately. Patients who perceived themselves to be at higher risk had better knowledge of warning signs. Compared with patients who underestimated their risk of stroke recurrence, those who accurately estimated or overestimated their risk less likely to smoke.

CONCLUSIONS

Most patients incorrectly estimated their risk of stroke recurrence. Communicating with patients about their future risk of recurrent stroke may help improve their stroke knowledge and health behaviors. Implementation of the Comprehensive Reminder System based on the Health Belief Model focusing on risk education aimed at prevention of stroke recurrence is warranted in China.

Recognizing a Heart Attack: Patients' Knowledge of Cardiovascular Risk Factors and Its Relation to Prehospital Decision Delay in Acute Coronary Syndrome

In acute coronary syndromes (ACSs), longer decision delay - the time patients wait before seeking medical attention after symptoms have started - increases the risk of complications and death. However, many patients wait much longer than recommended and research is needed investigating how patient decision delay can be reduced. In a cross-sectional study of 120 ACS survivors, we investigated the relationship between knowledge of cardiovascular risk factors and decision delay. Several days after the onset of a cardiac event, patients completed a questionnaire measuring demographics, decision delay, objective knowledge of cardiovascular risks factors and of ACS symptoms, and subjective perceptions of symptoms during the cardiac episode. Relevant clinical data were extracted from patients' medical records. In a multiple linear regression analysis, controlling for demographic and clinical factors, objective knowledge of cardiovascular risk factors and ACS symptoms, and subjective attributions of symptoms to a cardiac cause were related to shorter decision delays. Among patients with relatively high knowledge of risk factors, only 5% waited more than 1 h to seek help, compared to 22% among patients with relatively low knowledge. These results suggest that knowledge of the factors that increase the risk of developing cardiovascular disease could play a role in patient decision making during an acute cardiac event. We discuss methodological issues and potential underlying mechanisms related to decision heuristics and biases, which can inform future research.

Mismatch between self-perceived and calculated cardiometabolic disease risk among participants in a prevention program for cardiometabolic disease: a cross-sectional study

Background

The rising prevalence of cardiometabolic diseases (CMD) calls for effective prevention programs. Self-assessment of CMD risk, for example through an online risk score (ORS), might induce risk reducing behavior. However, the concept of disease risk is often difficult for people to understand. Therefore, the study objective was to assess the impact of communicating an individualized CMD risk score through an ORS on perceived risk and to identify risk factors and demographic characteristics associated with risk perception among high-risk participants of a prevention program for CMD.

Methods

A cross-sectional analysis of baseline data from a randomized controlled trial conducted in a primary care setting. Seven thousand five hundred forty-seven individuals aged 45–70 years without recorded CMD, hypertension or hypercholesterolemia participated. The main outcome measures were: 1) differences in cognitive and affective risk perception between the intervention group - who used an ORS and received an individualized CMD risk score- and the control group who answered questions about CMD risk, but did not receive an individualized CMD risk score; 2) risk factors and demographic characteristics associated with risk perception.

Results

No differences were found in cognitive and affective risk perception between the intervention and control group and risk perception was on average low, even among high-risk participants. A positive family history for diabetes type 2 (β0.56, CI95% 0.39–0.73) and cardiovascular disease (β0.28, CI95% 0.13–0.43), BMI ≥25 (β0.27, CI95% 0.12–0.43), high waist circumference (β0.25, CI95% 0.02–0.48) and physical inactivity (β0.30, CI95% 0.16–0.45) were positively associated with cognitive CMD risk perception in high-risk participants. No other risk factors or demographic characteristics were associated with risk perception.

Conclusions

Communicating an individualized CMD risk score did not affect risk perception. A mismatch was found between calculated risk and self-perceived risk in high-risk participants. Family history and BMI seem to affect the level of CMD risk perception more than risk factors such as sex, age and smoking. A dialogue about personal CMD risk between patients and health care professionals might optimize the effect of the provided risk information.

Reducing weight and increasing physical activity in people at high risk of cardiovascular disease: a randomised controlled trial comparing the effectiveness of enhanced motivational interviewing intervention with usual care

OBJECTIVE

The epidemic of obesity is contributing to the increasing prevalence of people at high risk of cardiovascular disease (CVD), negating the medical advances in reducing CVD mortality. We compared the clinical and cost-effectiveness of an intensive lifestyle intervention consisting of enhanced motivational interviewing in reducing weight and increasing physical activity for patients at high risk of CVD.

METHODS

A three-arm, single-blind, parallel-group randomised controlled trial was conducted in consenting primary care centres in south London. We recruited patients aged 40-74 years with a QRisk2 score ≥20.0%, which indicates the probability of having a CVD event in the next 10 years. The intervention was enhanced motivational interviewing which included additional behaviour change techniques and was delivered by health trainers in 10 sessions over 1 year, in either group (n=697) or individual (n=523) format. The third arm received usual care (UC; n=522). The primary outcomes were physical activity (mean steps/day) and weight (kg). Secondary outcomes were changes in low-density lipoprotein cholesterol and CVD risk score. We estimated the relative cost-effectiveness of each intervention.

RESULTS

At 24 months, the group and individual interventions were not more effective than UC in increasing physical activity (mean difference=70.05 steps, 95% CI -288.00 to 147.90 and mean difference=7.24 steps, 95% CI -224.01 to 238.50, respectively), reducing weight (mean difference=-0.03 kg, 95% CI -0.49 to 0.44 and mean difference=-0.42 kg, 95% CI -0.93 to 0.09, respectively) or improving any secondary outcomes. The group and individual interventions were not cost-effective at conventional thresholds.

CONCLUSIONS

Enhancing motivational interviewing with additional behaviour change techniques was not effective in reducing weight or increasing physical activity in those at high CVD risk.

Performance of the Framingham risk models and pooled cohort equations for predicting 10-year risk of cardiovascular disease: a systematic review and meta-analysis

BACKGROUND

The Framingham risk models and pooled cohort equations (PCE) are widely used and advocated in guidelines for predicting 10-year risk of developing coronary heart disease (CHD) and cardiovascular disease (CVD) in the general population. Over the past few decades, these models have been extensively validated within different populations, which provided mounting evidence that local tailoring is often necessary to obtain accurate predictions. The objective is to systematically review and summarize the predictive performance of three widely advocated cardiovascular risk prediction models (Framingham Wilson 1998, Framingham ATP III 2002 and PCE 2013) in men and women separately, to assess the generalizability of performance across different subgroups and geographical regions, and to determine sources of heterogeneity in the findings across studies.

METHODS

A search was performed in October 2017 to identify studies investigating the predictive performance of the aforementioned models. Studies were included if they externally validated one or more of the original models in the general population for the same outcome as the original model. We assessed risk of bias for each validation and extracted data on population characteristics and model performance. Performance estimates (observed versus expected (OE) ratio and c-statistic) were summarized using a random effects models and sources of heterogeneity were explored with meta-regression.

RESULTS

The search identified 1585 studies, of which 38 were included, describing a total of 112 external validations. Results indicate that, on average, all models overestimate the 10-year risk of CHD and CVD (pooled OE ratio ranged from 0.58 (95% CI 0.43-0.73; Wilson men) to 0.79 (95% CI 0.60-0.97; ATP III women)). Overestimation was most pronounced for high-risk individuals and European populations. Further, discriminative performance was better in women for all models. There was considerable heterogeneity in the c-statistic between studies, likely due to differences in population characteristics.

CONCLUSIONS

The Framingham Wilson, ATP III and PCE discriminate comparably well but all overestimate the risk of developing CVD, especially in higher risk populations. Because the extent of miscalibration substantially varied across settings, we highly recommend that researchers further explore reasons for overprediction and that the models be updated for specific populations.

Perceived Risk of Cardiovascular Disease and Health Behaviors in Black College Students

For college students, the transition from adolescence to young adulthood can be a time of increased stress and negative health behaviors, such as poor diet and physical inactivity, that may lead to cardiovascular disease (CVD), the primary cause of death in the United States. Blacks are disproportionately prone to CVD. Perception of disease risk is a critical predictor of engagement in healthy lifestyle activities intended to reduce CVD development. This project examined the relationship between perceived risk of CVD and health behaviors in Black HBCU students aged 18-25 years. All participants (n = 14) perceived that they were not at risk for heart disease within the next 10 years. Almost half (n = 6, 42.86%) had moderately high CVD risk scores, and three (21.43%) were at high risk for developing CVD. Scores on the subscales for dread risk, risk, and unknown risk were 28.29, 37.67, and 43.86, respectively. Total scores for perceived risk of heart disease ranged from 20 to 80. The Spearman's correlation between these Black college students' perceived dread risk and health responsibility was positive and moderately correlated (r_s = 0.62, p = 0.019). A negative and moderate correlation was demonstrated between unknown perceived risk and health responsibility (r_s = -0.54, p = 0.046). Thus, higher risk perception is correlated with greater health responsibility, while low risk perception is correlated with less health responsibility. Barriers to healthy lifestyle behaviors identified by the sample included lack of time and sleep, physical inactivity, cost, convenience of unhealthy foods, and low perception of developing CVD. A major implication is the benefit of implementing interventions to modify risk perception and college-specific barriers that increase CVD risk.

Preventing recurrent events in survivors of acute coronary syndromes in Australia: consensus recommendations using the Delphi process

OBJECTIVE

There remain substantial gaps in implementation of evidence-based care in patients with acute coronary syndromes (ACS) in Australia, which contribute to high recurrent event rates. Improved translation of evidence into effective action is a key health-care priority. We engaged cardiovascular experts from across Australia to develop straightforward, easily actionable recommendations on key medications to use following ACS.

METHODS

An eight-person steering committee (SC) reviewed the published evidence and developed an initial set of statements to be developed into consensus recommendations using a modified Delphi technique. A panel of 21 expert cardiologists in the ACS field (including the SC) voted on their level of agreement with the statements using a 6 point Likert scale. Statements that did not reach consensus (≥80% agreement) were reviewed by the SC, modified as appropriate based on input from the panel and circulated for re-voting.

RESULTS

Twenty-eight statements were developed by the SC across six classes of medication: low-density lipoprotein (LDL) cholesterol lowering agents, aspirin, dual antiplatelet therapy, renin-angiotensin-aldosterone system inhibitors, beta blockers and "other". Twenty-six recommendations were endorsed by the voting panel; two statements did not reach consensus.

CONCLUSIONS

Despite the extensive evidence base and detailed guidelines outlining best practice post ACS, there remain considerable gaps in translating these into everyday care. We used an internationally recognized technique to develop practical consensus recommendations on medical treatment following ACS. These simple, up-to-date recommendations aim to improve evidence-based medication use and thereby reduce the risk of future cardiovascular events for Australian patients with ACS.

Awareness of Individual Cardiovascular Risk Factors and Self-Perception of Cardiovascular Risk in Women

BACKGROUND

Cardiovascular risk factors (CVRFs) self-perception by women may be inaccurate.

MATERIALS AND METHODS

A questionnaire was completed anonymously Online by women who self-reported their personal CVRF levels including age, weight, contraceptive use, menopausal status, smoking, diet and physical activities. Self-perceived risk was matched to actual cardiovascular risk according to the Framingham score.

RESULTS

Among 5,240 young and middle-aged women with a high educational level, knowledge of personal CVRFs increased with age, from 51-90% for blood pressure (BP), 22-45% for blood glucose and 15-47% for blood cholesterol levels, between 30 and 65 years, respectively. This knowledge was lower for smoking compared with nonsmoking women: 62.5% vs. 74.5% for BP (P < 0.001), 22.7% vs. 33.8% for blood glucose (P < 0.001), 21.9% vs. 32.0% for cholesterol levels (P < 0.001). Knowledge of BP level was reduced among women using an estrogen-progestogen contraception (56.8% vs. 62.1%, P = 0.0031) and even more reduced among smokers (52.2%, P < 0.001). Conversely, women with leisure-time physical or sportive activity (60.5%), were less overweight or obese (22.4% vs. 34.2%, P < 0.001). They reported better knowledge of BP (72.4% vs. 68.3%, P < 0.001), blood cholesterol (31.1% vs. 26.4%, P < 0.001) and glucose levels (32.7% vs. 27.8%, P < 0.001). Self-perceived cardiovascular risk was rated low by 1,279 (20.4%), moderate by 3,710 (63.3%) and high by 893 (16.3%) women. Among 3,386 women tested using the Framingham score, 40.8% were at low, 25.2% at moderate and 33.8% at high risk.

CONCLUSIONS

Knowledge of CVRFs and self-perception of individual risk are inaccurate in women. Educational interventions should be emphasized.

Predictors of the Perception of Smoking Health Risks in Smokers With or Without Schizophrenia

OBJECTIVE

This study sought to examine the predictors of health risk perception in smokers with or without schizophrenia.

METHODS

The health risk subscale from the Smoking Consequences Questionnaire was dichotomized and used to measure health risk perception in smokers with (n = 67) and without schizophrenia (n = 100). A backward stepwise logistic regression was conducted using variables associated at the bivariate level to determine multivariate predictors.

RESULTS

Overall, 62.5% of smokers without schizophrenia and 40.3% of smokers with schizophrenia completely recognize the health risks of smoking (p ≤ .01). Multivariate predictors for smokers without schizophrenia included: sex (Exp (B) = .3; p < .05), Smoking Consequences Questionnaire state enhancement (Exp (B) = .69; p < .01), and craving relief (Exp (B) = 1.8; p < .01). Among smokers with schizophrenia, predictors were education (Exp (B) = .7; p < .05), nicotine dependence (Exp (B) = .5; p < .01), motivation to quit (Exp (B) = 1.8; p < .01), and Smoking Consequences Questionnaire craving relief (Exp (B) = 1.8; p < .01).

CONCLUSIONS

There was overlap and differences between predictors in smokers with and without schizophrenia. Commonly used techniques for education on the health consequences of cigarettes may work in smokers with schizophrenia, but intervention efforts specifically tailored to smokers with schizophrenia might be more efficacious.
