The General Public's Awareness of Early Symptoms of and Emergency Responses to Acute Myocardial Infarction and Related Factors in South Korea: A National Public Telephone Survey

Recognition of Early Cardiovascular Disease Symptoms in Hypertensive and Dyslipidemic Individuals of Icheon, Korea: Insights into Educational Levels and Health Literacy

The study aimed to explore the relationship between the presence of hypertension or dyslipidemia and the recognition of early symptoms of cardiovascular diseases (CVD), particularly acute myocardial infarction (AMI) and stroke. It is crucial for individuals with hypertension or dyslipidemia to recognize early symptoms of AMI and stroke, as timely and appropriate intervention can lead to favorable health outcomes. The study enrolled 104 participants aged 19 and above who are current residents of the Icheon region, Gyeonggi, Korea. The assessment of early symptoms of AMI and stroke utilized adapted items from the Korea Community Health Survey. In consideration of health literacy and education attainment, logistic regression analyses were conducted. While there was no significant association between hypertension and awareness of AMI or stoke symptoms, individuals with dyslipidemia demonstrated enhanced recognition of specific AMI symptoms, such as 'sudden chest pain or pressure' and 'sudden feeling of breathlessness'. No significant associations were observed between hypertension or dyslipidemia and awareness of stroke symptoms. The study emphasized the significance of targeted health education programs for individuals with chronic conditions to enhance their awareness of early symptoms of AMI and stroke.

Age and healthy lifestyle behavior's disparities and similarities on knowledge of myocardial infarction symptoms and risk factors among public and outpatients in a resource-limited setting, cross-sectional study in greater Gaborone, Botswana

OBJECTIVES

In this cross-sectional study from Botswana, we investigated knowledge of myocardial infarction (MI) symptoms and risk factors among the general public and outpatients with MI risk factors based on age and lifestyle behaviors, in addition to assessing associations with sociodemographic and MI risk factors.

METHOD

Open-ended questionnaires about 8 MI symptoms and 10 risk factors, were administered by research assistants to a representative selection of outpatients (n = 525) and the public (n = 2248). Weight and height were measured in all participants and BMI was calculated. Knowledge scores were compared between the two groups. We examined whether sociodemographic and MI risk factors had impact on the scores. Analyses were further adjusted for lifestyle behavior (smoking status, dietary status and physical activities).

RESULTS

The valid response rate was 97.9% comprising 97.8% for the public (n = 2199) and 98.1% for outpatients (n = 515). Public respondents (35.2 ± 12.3 years) were younger than outpatients (38.5 ± 12.6 years). The public comprised 56.9% females while outpatients 54.6%. In general, outpatients had higher knowledge of MI symptoms than the public, with mean scores ± SD of 3.49 ± 2.84 vs 2.80 ± 2.54. Outpatients also had higher knowledge score of MI risk factors than the public, with mean scores, 5.33 ± 3.22 vs 3.82 ± 3.07. For MI symptoms, outpatients were more aware than the public for chest pains among all ages, for arm pain/ numbness, neck/ jaw pain radiating to/ from chest, and feeling sick or looking pallor on the skin among those aged 35-49 years. Among both the public and outpatients, lower knowledge of both MI symptoms and risk factors was associated with primary education, not residing/working together, history of hypertension, no history of heart disease/stroke, and obesity. There were similarities and disparities on MI knowledge among respondents with various numbers of healthy lifestyle behaviours.

CONCLUSION

Results call for urgent educational campaigns on awareness and knowledge of MI and using strategies based on age and lifestyle behavior.

Assessing Awareness and Actions Must Be Taken in Acute Myocardial Infarction: A Cross-Sectional Study on the General Population in Alahssa, Saudi Arabia

INTRODUCTION

Acute myocardial infarction (AMI), commonly referred to as a heart attack, is a leading global cause of mortality, necessitating immediate recognition and appropriate actions. This study aims to assess AMI awareness and response among the general population in Alahssa, Saudi Arabia.

METHODOLOGY

A descriptive cross-sectional design was employed, with surveys distributed via online platforms. Participants aged 18 years and older, residing in Alahssa, and providing informed consent were included.

RESULTS

Among 406 participants, 74.1% had good knowledge levels. Notably, 216 (53.2%) recognized calling an ambulance as the initial response to AMI symptoms. The Internet (140, 28.9%) and healthcare professionals (113, 23.3%) were primary information sources, with "sudden pain or discomfort in arms or hands" (287, 27.8%) as the most recognized symptom. "Obesity" and "heart disease" (304, 12.3%) were the most common risk factors. Demographic variations in knowledge were observed.

CONCLUSION

This study highlights the need to enhance public awareness of AMI, particularly among specific demographic groups. Targeted educational campaigns can improve knowledge, promote appropriate actions, and ultimately enhance outcomes during AMI events in Alahssa, Saudi Arabia.

Identifying and Solving Gaps in Pre- and In-Hospital Acute Myocardial Infarction Care in Asia-Pacific Countries

Acute myocardial infarction (AMI) is a major cause of morbidity and mortality in the Asia-Pacific region, and mortality rates differ between countries in the region. Systems of care have been shown to play a major role in determining AMI outcomes, and this review aims to highlight pre-hospital and in-hospital system deficiencies and suggest possible improvements to enhance quality of care, focusing on Korea, Japan, Singapore and Malaysia as representative countries. Time to first medical contact can be shortened by improving patient awareness of AMI symptoms and the need to activate emergency medical services (EMS), as well as by developing robust, well-coordinated and centralized EMS systems. Additionally, performing and transmitting pre-hospital electrocardiograms, algorithmically identifying patients with high risk AMI and developing hospital networks that appropriately divert such patients to percutaneous coronary intervention-capable hospitals have been shown to be beneficial. Within the hospital environment, developing and following clinical practice guidelines ensures that treatment plans can be standardised, whilst integrated care pathways can aid in coordinating care within the healthcare institution and can guide care even after discharge. Prescription of guideline directed medical therapy for secondary prevention and patient compliance to medications can be further optimised. Finally, the authors advocate for the establishment of more regional, national and international AMI registries for the formal collection of data to facilitate audit and clinical improvement.

Comparing Gerd and Non-GERD Patients Regarding Knowledge Level of Acute Myocardial Infarction Symptoms, Risk Factors and Immediate Action Must Be Taken in Eastern Province, Saudi Arabia

INTRODUCTION

A major cause of death globally is cardiovascular disease (CVD). Chest pain, nausea, vomiting, and heartburn are common symptoms of acute myocardial infarction (AMI). Chest pain is also the main symptom of gastroesophageal reflux disease (GERD). Therefore, the differential diagnosis of chest pain can become more challenging when GERD and AMI coincide. This study evaluated and compared the knowledge of the signs, symptoms, and immediate action that must be taken regarding AMI among GERD and non-GERD patients.

METHODOLOGY

An observational cross-sectional study using an online questionnaire was created and published between October and November 2022 to collect data from Saudi males and females 18 or older willing to participate in the study. Participants who were not Saudi had declined to complete the survey or had not fully completed it was excluded. The questionnaire contained three sections; after collecting informed consent, it made inquiries regarding respondents' GERD status, demographic information, and knowledge and attitudes regarding GERD.

RESULTS

This study included 691 responses from 300 non-GERD participants and 391 GERD participants. The study showed a high level of awareness (75.5%) of GERD, with significant differences in the level of awareness according to marital status, education levels, and occupation status. There was no significant difference in the level of awareness according to gender and GERD diagnosis, where the p-value > 0.05. The most common source of information about AMI was the Internet, followed by health care professionals. The most commonly known symptoms of AMI were sudden pain or discomfort in the chest, followed by a sudden shortness of breath. Additionally, there was no significant association between the diagnosis of GERD and known risk factors. The association between GERD and other diseases (chi-square = 46.94, p-value 0.01). Obesity and smoking were the two main risk factors for heart attacks.

CONCLUSION

This study demonstrated that there was no significant difference between GERD and non-GERD participants regarding the knowledge and awareness level of AMI. Moreover, it showed that there was a lack of general knowledge and awareness of AMI in Saudi Arabia. The authors recommend initiating more awareness programs in Saudi Arabia to inform people about AMI and cardiovascular disease. More research is required to determine whether other patients are aware of AMI.

Engaging social activities prevent stroke and myocardial infraction by raising awareness of warning symptoms: A cross-sectional survey study

Background

Stroke and myocardial infarction (MI) are medical emergencies, and early treatment within the golden hour is crucial for good prognosis. Adequate knowledge about the warning symptoms can shorten the onset-to-door time. Various factors affect the level of awareness, including social activity. This study aimed to determine if engaging in social activity is associated with the awareness of the warning symptoms of stroke and MI.

Methods

This cross-sectional study analyzed 451,793 participants from the 2017 and 2019 Korea Community Health Survey. Based on five questions for each of stroke and MI symptoms, participants were divided into an awareness group (replied "Yes" to all five questions) and unawareness group. Engagement in social activities (i.e., religious, friendship, leisure, and volunteer activity) was evaluated through a questionnaire. Multiple logistic regression analysis was performed to evaluate the relation between social activity and awareness of warning symptoms.

Results

Overall, 52.6% participants were aware of the warning symptoms of stroke, and 45.8% of MI. Regular engagement in at least one social activity, particularly friendship or volunteer activity, was associated with better awareness of the warning symptoms, both stroke (OR: 1.21, 95% CI: 1.20-1.23) and MI (OR: 1.22, 95% CI: 1.20-1.24). Additionally, more diverse types of social activities were associated with higher levels of awareness. Relationship between social activity and awareness showed positive association with participants older than 60 years, rural residents, or with low socioeconomic status.

Conclusion

Engagement in social activity was significantly associated with better knowledge about the warning symptoms of stroke and MI. For early hospital treatment after symptom onset, participation in social activities could be beneficial.

Latent class cluster analysis of knowledge on acute myocardial infarction in community residents: a cross-sectional study in Tianjin, China

OBJECTIVE

Public knowledge of early onset symptoms and risk factors (RF) of acute myocardial infarction (AMI) is very important for prevention, recurrence and guide medical seeking behaviours. This study aimed to identify clusters of knowledge on symptoms and RFs of AMI, compare characteristics and the awareness of the need for prompt treatment.

DESIGN

Multistage stratified sampling was used in this cross-sectional study. Latent GOLD Statistical Package was used to identify and classify the respondent subtypes of the knowledge on AMI symptoms or modifiable RFs. Multivariable logistic regression was performed to identify factors that predicted high knowledge membership.

PARTICIPANTS

A structured questionnaire was used to interview 4200 community residents aged over 35 in China. 4122 valid questionnaires were recovered.

RESULTS

For AMI symptoms and RFs, the knowledge levels were classified into two or three distinct clusters, respectively. 62.7% (Symptom High Knowledge Cluster) and 39.5% (RF High Knowledge Cluster) of the respondents were able to identify most of the symptoms and modifiable RFs. Respondents who were highly educated, had higher monthly household income, were insured, had regular physical examinations, had a disease history of AMI RFs, had AMI history in immediate family member or acquaintance or had received public education on AMI were observed to have higher probability of knowledge on symptoms and RFs. There was significant difference in awareness of the prompt treatment in case of AMI occurs among different clusters. 'Calling an ambulance' was the most popular option in response of seeing others presenting symptoms of AMI.

CONCLUSIONS

A moderate or relatively low knowledge on AMI symptoms and modifiable RFs was observed in our study. Identification of Knowledge Clusters could be a way to detect specific targeted groups with low knowledge of AMI, which may facilitate health education, further reduce the prehospital delay in China and improve patient outcomes.

Knowledge of Symptoms of Acute Myocardial Infarction, Reaction to the Symptoms, and Ability to Perform Cardiopulmonary Resuscitation: Results From a Cross-sectional Survey in Four Regions in Germany

Background

Ischemic heart disease affects 126 million individuals globally which illustrates the importance of finding ways to decrease mortality and morbidity in case of an acute myocardial infarction (AMI). Since knowledge of symptoms, correct reaction to symptoms, and ability to perform cardiopulmonary resuscitation (CPR) decreases the time from symptoms-onset to reperfusion, which leads to lower AMI mortality, we aimed to examine those factors and identify predicting variables in regions with low and high AMI mortality rates.

Methods

We conducted a cross-sectional online survey including 633 respondents from the general population in four federal states in Germany with low and high AMI mortality and morbidity rates. We used uni- and multivariable regressions to find health-related and sociodemographic factors associated with knowledge, reaction to symptoms, and skills in CPR.

Results

Out of 11 symptoms, the mean of correctly attributed AMI symptoms was 7.3 (standard deviation 1.96). About 93% of respondents chose to call an ambulance when witnessing an AMI. However, when confronted with the description of a real-life situation, only 35 and 65% of the participants would call an ambulance in case of abdominal and chest pain, respectively. The predicting variables for higher knowledge were being female, knowing someone with heart disease, and being an ex-smoker compared to people who never smoked. Higher knowledge was associated with adequate reaction in the description of a real-life situation and ability to perform CPR. Prevalence ratio for being able to perform CPR was lower in females, older participants, and participants with low educational level. About 38% of participants state to know how to perform CPR. Our results indicate rather no difference regarding knowledge, reaction to AMI symptoms, and ability to perform CPR among different regions in Germany.

Conclusions

Knowledge of symptoms and first responder reaction including skills in CPR is inadequate when confronted with the description of a real-life situation. Educational health campaigns should focus on conveying information close to real-life situations. Interventions for enhancing ability to perform CPR should be compulsory in regular intervals. Interestingly, we found no difference regarding the factors in regions with high and low AMI mortality rates in Germany.

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.

Public awareness of early symptoms of acute myocardial infarction among Saudi population

Introduction:

Globally speaking, cardiovascular disease is the leading cause of mortality, with coronary artery disease (CAD) contributing to half of the cases. A major complication of CAD is myocardial infarction (MI). The clinical outcomes of MI are predominantly time-dependent; therefore, it is paramount that the general public is familiar with the early symptoms of MI.

Aim:

The main objective is to gauge the local public awareness of the early symptoms of MI, and their knowledge of the best course of action to be taken from the onset of symptoms.

Method:

A cross-sectional study was conducted using google forms. Participants were randomly selected through multiple social media platforms. The study included Saudi citizens who were 18 years or older, with no current or prior experience in the health care field. The questionnaire assessed the participants' awareness of 14 risk factors for CAD. The variables investigated were participants' knowledge of the symptoms, causes, appropriate course of action to be taken, and the risk factors of CAD.

Results:

A total of 1689 participants were involved in this study. Sixty percent were females, and 29.2% were in the age group of 18–24 years. Seventy-three percent of the participants knew the definition of heart attack, and 90% knew that chest pain is a symptom of a heart attack. Approximately, 75% of the participants recognized that hypertension, cigarette smoking, and high cholesterol are the risk factors of MI. In terms of knowledge, Al Madinah province obtained the highest score when compared with other regions.

Conclusion:

This study showed the overall knowledge and awareness of CAD was suboptimal, indicating that awareness initiatives and patient education of CAD need more work in Saudi Arabia, especially in high-risk groups and lower education groups. More studies are needed to identify the efficiency and population access of different approaches for CAD awareness.

Public knowledge of stroke and heart attack symptoms in China: a cross-sectional survey

OBJECTIVE

Stroke and ischaemic heart disease have become the leading causes of death in China. We evaluated recognition of stroke and heart attack symptoms and stroke treatment-seeking behaviour in a large representative sample of the Chinese adult population and explored characteristics associated with recognition rates.

DESIGN

Cross-sectional survey.

SETTING

Household interviews.

PARTICIPANT

3051 Chinese adults aged between 18 and 69 (50.7% female) were interviewed between January and March 2019.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary measures include recognitions of stroke and heart attack symptoms and stroke treatment-seeking behaviour. Secondary measures include numeracy level, sociodemographics and prior history of cardiovascular diseases and high blood pressure.

RESULTS

Participants on average recognised 5.2 out of 14 stroke symptoms and 2.6 out of 6 heart attack symptoms. In the presence of stroke symptoms, three quarters of participants would take immediate action and call an ambulance, yet the second most common action was to advise the person to see a doctor (59%) rather than to consult a doctor immediately (34%). Recognition of atypical heartattack symptoms, such as nausea and feeling of anxiety, was poor. Symptom recognition rates were higher in females, people with a personal or family/friend history of cardiovascular events, those with higher numeracy scores, and for stroke symptoms, participants with high (versus low) education level. Furthermore, symptom recognition rate was negatively correlated with burden of cardiovascular diseases across the four economic regions of China.

CONCLUSION

Recognition of stroke and heart-attack symptoms was moderate and there remains a gap between recognising symptoms and taking immediate action. Interventions focusing on simple symptom detection tools and on building numerical competencies may help reduce the burden of cardiovascular diseases in China.

Predictors of anticipated coping behavior at myocardial infarction symptom onset among a nationwide sample of Korean adults

OBJECTIVES

This cross-sectional study based on the health belief model investigated predictors of anticipated coping behavior at myocardial infarction (MI) symptom onset using secondary data from the 2017 Korea Community Health Survey.

METHODS

Modifying variables (socioeconomic, health knowledge, perceived threat) were selected as independent variables and anticipated coping behavior at MI symptom onset as the dependent variable. Calling 911 was classified as the correct anticipated coping behavior, while visiting a hospital or an oriental hospital, calling family, and others were classified as incorrect.

RESULTS

Of 227,740 participants, 83.2% reported correct anticipated coping behaviors. The likelihood of calling 911 was low if participants experienced atypical symptoms (jaw, neck, back, arm, and shoulder pain), even if they were aware of those symptoms. However, 69.9% of participants who were aware of typical symptoms (chest pain) stated that they would call-911. Sex, age, hypertension, dyslipidemia, obesity, and awareness of MI symptoms affected the correct anticipated coping behavior.

CONCLUSIONS

Correct coping abilities among the general public are vitally important for early treatment of MI patients and reduction of hospitalization time. Members of the general public in their 20s and 30s, 60 years of age or older, with cardiovascular risk factors (male sex, hypertension, dyslipidemia, and obesity), and who are not aware of MI symptoms should be educated about the typical and atypical symptoms of MI. Emergency medical services should be called without delay if needed, and public relations activities should be carried out to raise awareness that anyone can use emergency medical services.

Public Awareness of and Action towards Heart Attack Symptoms: An Exploratory Study

Background: Cardiovascular disease (CVD) is still the leading cause of mortality worldwide, and Malaysia is not an exception in this regard. The current research is an attempt to explore symptom awareness of and necessary actions in response to heart attack (HA) among lay public. Methods: This is a cross-sectional study design, and a survey was conducted from May to July 2018 among general public in Kuantan, Pahang state, Malaysia. Results: A total of 393 respondents recruited. Slightly more than one-fourth of the respondents (26.35%) were aware of HA symptoms like pain and/or discomfort in the jaw, neck, or back, while 71.65% showed awareness only of chest pain or discomfort as symptoms. Only 35.6% reported to call an ambulance if they experience someone suffering from HA symptoms, while 82% recognized ≥1 symptom, and only 11.5% recognized all five HA symptoms. Very few respondents, i.e., 1.3% reported awareness about correct recognition of all five HA symptoms. Respondents who had diabetes and hypercholesteremia were more likely to recognize all five HA symptoms. For those who had excellent awareness of all five HA symptoms, the odds ratio (OR) were significantly higher among single respondents (OR 0.023; 95% CI 0.001–0.594), Malay (OR 0.376; 95% CI 0.193–0.733), and those who received information associated with HA (OR 7.540; 95% CI 2.037–27.914). However, those who were aware that HA requires quick treatment had significantly low odds ratio (OR 0.176; 95% CI 0.044–0.710). Conclusions: The awareness of and action towards the signs and symptoms of HA among the public were poor.

Cardiac symptom attribution and knowledge of the symptoms of acute myocardial infarction: a systematic review

BACKGROUND

Since the knowledge of the symptoms of acute myocardial infarction (AMI) may reduce the decision time for patients to seek help in case of an AMI, we aimed to summarize evidence on the knowledge of the AMI symptoms and the symptom attribution in case of an acute coronary syndrome (ACS).

METHODS

Therefore, we systematically searched the databases PubMed, CINAHL, Embase, and Cochrane Library for relevant studies published between January 1, 2008 and 2019 (last search August 1, 2019).

RESULTS

A total of 86 studies were included, with a composite sample size of 354,497 participants. The weighted mean of the knowledge scores for the symptoms of AMI of 14,420 participants from the general population, was 42.1% (when maximum score was considered 100%) and 69.5% for 7642 cardiac patients. There was a substantially better level of knowledge for six symptoms ('chest pain or discomfort', 'shortness of breath', 'pain or discomfort in arms or shoulders', 'feeling weak, lightheaded, or faint', 'pain or discomfort in the jaw, neck, or back', and 'sweating') (49.8-88.5%) compared to the four less obvious/atypical symptoms 'stomach or abdominal discomfort', 'nausea or vomiting', 'headache', and 'feeling of anxiety' (8.7-36.7%). Only 45.1% of 14,843 patients, who experienced ACS, have correctly attributed their symptoms to a cardiac cause.

CONCLUSION

In conclusion, we found a moderate to good knowledge of "classic" and insufficient knowledge of less obvious symptoms of AMI. This might suggest that increasing knowledge about less obvious symptoms of AMI could be beneficial. It appears also important to address cardiac attribution of symptoms.

Public knowledge of cardiovascular disease and response to acute cardiac events in three municipalities in Brazil

Objective

To conduct a landscape assessment of public knowledge of cardiovascular disease risk factors and acute myocardial infarction symptoms, cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) awareness and training in three underserved communities in Brazil.

Methods

A cross-sectional, population-based survey of non-institutionalised adults age 30 or greater was conducted in three municipalities in Eastern Brazil. Data were analysed as survey-weighted percentages of the sampled populations.

Results

3035 surveys were completed. Overall, one-third of respondents was unable to identify at least one cardiovascular disease risk factor and 25% unable to identify at least one myocardial infarction symptom. A minority of respondents had received training in CPR or were able to identify an AED. Low levels of education and low socioeconomic status were consistent predictors of lower knowledge levels of cardiovascular disease risk factors, acute coronary syndrome symptoms and CPR and AED use.

Conclusions

In three municipalities in Eastern Brazil, overall public knowledge of cardiovascular disease risk factors and symptoms, as well as knowledge of appropriate CPR and AED use was low. Our findings indicate the need for interventions to improve public knowledge and response to acute cardiovascular events in Brazil as a first step towards improving health outcomes in this population. Significant heterogeneity in knowledge seen across sites and socioeconomic strata indicates a need to appropriately target such interventions.

2020 Focused Update of the 2012 Guidelines of the Taiwan Society of Cardiology for the Management of ST-Segment Elevation Myocardial Infarction

One of the major missions of the Taiwan Society of Cardiology is to publish practice guidelines that are suitable for local use in Taiwan. The ultimate purpose is to continuously improve cardiovascular health care from the implementation of the recommendations in the guidelines. Despite recent improvement of medical care, patients with ST-segment elevation myocardial infarction (STEMI) still carry a high morbidity and mortality. There have been many changes in the concepts of STEMI diagnosis and treatment in recent years. The 2020 focused update of the 2012 guidelines of the Taiwan Society of Cardiology for the management of STEMI is an amendment of the 2012 guidelines based on the newest published scientific data. The recommendations in this focused update provide the diagnosis and treatment strategy for STEMI that should be generally implemented in Taiwan. Nevertheless, guidelines never completely replace clinical judgment and medical decision still should be determined individually.

Factors affecting awareness of myocardial infarction symptoms among the general public in Korea

OBJECTIVES

We aimed to determine the level of awareness of myocardial infarction (MI) symptoms among the general public in Korea and identify factors affecting awareness of MI symptoms using data from the 2017 Korea Community Health Survey (KCHS).

METHODS

This is a cross-sectional study using KCHS data. Based on five questions about MI symptoms, participants were divided into an awareness group (replied ‘yes’ to all five questions) and an unawareness group (replied ‘no’ or ‘not sure’ to at least one of five questions) for analysis.

RESULTS

Of a total of 228,281 participants, 42.4% were aware of MI symptoms. There was a high level of awareness of chest pain and shortness of breath, but a low level of awareness of gastrointestinal symptoms and pain in the arm, shoulder, jaw, neck, and back. While women had a higher level of overall awareness relative to men, they showed a lower level of awareness regarding chest pain and discomfort. The factors affecting awareness of MI symptoms were gender, age, education level, occupation, smoking, drinking, physical inactivity, and cardiovascular disease risk factors.

CONCLUSIONS

In order to enhance awareness of MI symptoms among the general population, appropriate education and promotion efforts must be implemented based on gender, age, education level, and occupation. Moreover, active efforts by the government, educational institutions, and medical institutions are necessary to improve awareness of both typical and atypical MI symptoms. Furthermore, health policies to promote reduced smoking and drinking and increased physical activity, as well as continuous monitoring and management of individuals with cardiovascular disease risk factors, are required.

Development of questionnaire on awareness and action towards symptoms and risk factors of heart attack and stroke among a Malaysian population

Background

The awareness of symptoms and action towards heart attack and stroke is important to reduce the morbidity and mortality in both developed and developing countries. The aim of this study was to develop a questionnaire on awareness and action towards symptoms and risk factors of heart attack and stroke among lay public in Malaysia. The questionnaire was developed in both English and Bahasa Melayu.

Methods

Primarily the questions were generated in English. Face and content validity were performed by five experts in Pharmacy Practice and Medicine. A translation as per guidelines into Malay language was performed; followed by face-to-face interview of 96 lay public in Kuantan, Pahang, Malaysia. For internal consistency, reliability was assessed utilizing Cronbach’s alpha.

Results

The mean ± SD of the awareness and action towards heart attack symptoms and risk factors was 65.52 ± 6.3, with a good internal consistency (Cronbach’s alpha = 0.75), whereas the mean of the awareness and action towards stroke symptoms and risk factors was 61.93 ± 7.11, with an accepted internal consistency (Cronbach’s alpha = 0.86).

Conclusion

The current validation research showed that the developed questionnaire is valid and reliable for assessing the awareness and action towards symptoms and risk factors of heart attack and stroke among lay public in Malaysia.

Epidemiology and Serum Metabolic Characteristics of Acute Myocardial Infarction Patients in Chest Pain Centers

BACKGROUND

We aimed to find a potential earlier diagnostic strategy for acute myocardial infarction (AMI) by investigating the epidemiology and serum metabolic characteristics of AMI patients in comparison with those of chest pain controls (CPCS).

METHODS

We conducted this prospective, non-randomized, observational study of patients with acute chest pain symptoms presenting to the Emergency Rooms (ER) in The People's Hospital of Guangxi Zhuang Autonomous Region, Nanning, Guangxi Province, China from January 2015 to July 2016. We included a cohort of 45 patients with AMI together with 45 age- and sex-matched CPCS. The epidemiology of AMI was collected, and the phenotypic characteristics of the serum metabolite composition of AMI patients were determined using a combination of 1H nuclear magnetic resonance (NMR)-based metabolomics and clinical assays.

RESULTS

The epidemiology showed that elderly AMI patients with chest pain syndrome presenting to ER have little awareness of their physical condition and compliance with medication. Significant serum metabolic differences observed between AMI patients and CPCS were highlighted by system differentiations in multiple metabolic pathways including anaerobic glycolysis, gluconeogenesis, tricarboxylic acid cycle (TCA cycle), protein biosynthesis, lipoprotein changes, choline and fatty acid metabolisms and intestinal microbial metabolism.

CONCLUSION

The epidemiology and serum metabolic phenotypes observed here demonstrated that integration of metabolomics with other techniques could be useful for better understanding the biochemistry of AMI and for potential AMI molecular diagnosis. We should improve the general public's awareness of AMI, including early symptoms, risk factors, emergency responses, and treatments for related comorbidities.

Low level of knowledge of heart attack symptoms and inappropriate anticipated treatment-seeking behaviour among older Chinese: a cross-sectional survey

BACKGROUND

Prehospital delay of acute myocardial infarction (AMI) is common globally, and Hong Kong-home of a rapidly ageing Chinese population-is not an exception. Seeking emergency medical care promptly is important for patients. Treatment-seeking behaviours have been shown to be associated with knowledge of AMI symptoms and specific cultural beliefs. This study aimed to assess the level of knowledge of AMI symptoms and expected treatment-seeking behaviour among older Chinese in Hong Kong.

METHODS

A cross-sectional population-based survey was conducted at the Elderly Health Centres in Hong Kong from March to September 2016. Face-to-face interviews were conducted with a structured questionnaire based on previous studies and local adaptations.

RESULTS

Among 1804 people aged 65 years and above who completed the questionnaire, chest pain (80.2%), palpitations (75.8%) and fainting (71.9%) were the major symptoms recognised as AMI related. Meanwhile, stomach ache (46.9%), coughing (45.4%) and neck pain (40.8%) were recognised as not AMI related. The mean expected discomfort intensity during AMI onset was 7.7 out of 10 (SD=2.1). Regarding the expected treatment-seeking behaviour, seeking non-emergent medical care was the most popular action when AMI symptoms emerged during the day, without chest pain or with lower discomfort intensity, whereas calling an ambulance was the most common option when AMI symptoms emerged at night or with high discomfort intensity.

CONCLUSIONS

To minimise delays in seeking treatment, future health education should focus on increasing the public knowledge of AMI symptoms and the need to call an ambulance during an emergency.

Public knowledge of cardiovascular disease and response to acute cardiac events in three cities in China and India

Objective

To inform interventions targeted towards reducing mortality from acute myocardial infarction (AMI) and sudden cardiac arrest in three megacities in China and India, a baseline assessment of public knowledge, attitudes and practices was performed.

Methods

A household survey, supplemented by focus group and individual interviews, was used to assess public understanding of cardiovascular disease (CVD) risk factors, AMI symptoms, cardiopulmonary resuscitation (CPR) and automated external defibrillators (AEDs). Additionally, information was collected on emergency service utilisation and associated barriers to care.

Results

5456 household surveys were completed. Hypertension was most commonly recognised among CVD risk factors in Beijing and Shanghai (68% and 67%, respectively), while behavioural risk factors were most commonly identified in Bangalore (smoking 91%; excessive alcohol consumption 64%). Chest pain/discomfort was reported by at least 60% of respondents in all cities as a symptom of AMI, but 21% of individuals in Bangalore could not name a single symptom. In Beijing, Shanghai and Bangalore, 26%, 15% and 3% of respondents were trained in CPR, respectively. Less than one-quarter of participants in all cities recognised an AED. Finally, emergency service utilisation rates were low, and many individuals expressed concern about the quality of prehospital care.

Conclusions

Overall, we found low to modest knowledge of CVD risk factors and AMI symptoms, infrequent CPR training and little understanding of AEDs. Interventions will need to focus on basic principles of CVD and its complications in order for patients to receive timely and appropriate care for acute cardiac events.
