Association Between Acute Myocardial Infarction Symptoms and Short- and Long-term Mortality After the Event. Can J Cardiol 2024; 40:1355-1366. [PMID: 38278322 DOI: 10.1016/j.cjca.2024.01.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 01/03/2024] [Accepted: 01/15/2024] [Indexed: 01/28/2024] Open
Abstract
BACKGROUND In this study, we investigated various acute myocardial infarction (AMI) symptoms and their associations with short-term (28 day) and long-term mortality. METHODS The analysis was based on 5900 patients, aged 25 to 84 years, with first-time AMI recorded by the population-based Myocardial Infarction Registry Augsburg between 2010 and 2017. Median follow-up time was 3.8 years (interquartile range: 1.1-6.3). As part of a face-to-face interview, the presence (yes/no) of 11 most common AMI symptoms at the acute event was assessed. Using multivariable-adjusted logistic regression and Cox regression models, the association between various symptoms and all-cause mortality was investigated. P values of the regression models were false discovery rate adjusted. RESULTS Pain in various body parts (chest pain, left and right shoulder/arm/hand, between shoulder blades), sweating, nausea/vomiting, dizziness and fear of death/feeling of annihilation were significantly associated with a decreased 28-day mortality after AMI. The pain symptoms and sweating were also significantly associated with a decreased long-term mortality. Shortness of breath was significantly associated with a higher long-term mortality. CONCLUSIONS The absence of several symptoms, including typical chest discomfort (chest pain or retrosternal pressure/tightness), is associated with unfavourable outcomes after AMI. This finding has implications for patient management and public health measures designed to encourage appropriate and prompt medical consultation of patients with atypical AMI symptoms.

Baseline fibroblast growth factor 23 is associated with long-term mortality in ST-elevation myocardial infarction-results from the augsburg myocardial infarction registry. Front Cardiovasc Med 2023; 10:1173281.

Abstract
Background The aim of this study was to investigate the association between inflammatory plasma protein concentrations and long-term mortality in patients with ST-elevation myocardial infarction (STEMI). Methods For 343 STEMI patients recorded between 2009 and 2013 by the population-based Myocardial Infarction Registry Augsburg, 92 inflammatory plasma proteins were measured at the index event using the OLINK inflammation panel. In multivariable-adjusted Cox regression models, the association between each plasma protein and all-cause long-term mortality was investigated. Median follow-up time was 7.6 (IQR: 2.4) years. For plasma protein that showed a strong association with long-term mortality, a 5-year survival ROC analysis was performed. Results One plasma protein, namely Fibroblast Growth Factor 23 (FGF-23), was particularly well associated with long-term mortality in the multivariable-adjusted Cox model with an FDR-adjusted p-value of <0.001 and a Hazard Ratio (HR) of 1.57 [95% CI: 1.29-1.91]. In the 5-years ROC analysis, an AUC of 0.6903 [95% CI: 0.594-0.781] was estimated for FGF-23. All other plasma protein didńt show strong associations, each marker with FDR-adjusted p-values >0.05 in the multivariable-adjusted Cox models. Conclusions FGF-23 is independently associated with long-term mortality after STEMI and might play an important role in the response to myocardial injury. The results suggest FGF-23 to be a useful marker in the long-term treatment of STEMI patients and a potential target for drug development.

Long-Term Predictors of Hospitalized Reinfarction after an Incident Acute Myocardial Infarction. LIFE (BASEL, SWITZERLAND) 2022; 12:life12122090. [PMID: 36556454 PMCID: PMC9784794 DOI: 10.3390/life12122090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 12/01/2022] [Accepted: 12/08/2022] [Indexed: 12/15/2022]
Abstract
The aim of this study was to compare characteristics of incident acute myocardial infarction (AMI) and first and second time reinfarctions in terms of sociodemographic characteristics, comorbidities, symptoms, treatment, clinical characteristics, medication and outcome. A further aim was to identify predictors for an increased risk of hospitalized reinfarction. Between 2000 and 2017, a total of 13,276 AMI cases were recorded by a population-based registry in the area of Augsburg, Germany, and were included in this study (11,871 incident events, 1217 cases of first-time reinfarction and 202 cases of second-time reinfarction). Median follow-up time was 5.3 years. For differences in baseline characteristics, Chi-square tests and analysis of variance (ANOVA) were calculated. To determine factors that are associated with an increased risk of hospitalized reinfarction COX regression models were fitted. Myocardial reinfarctions differ from incident events in some major characteristics such as the frequency of comorbidities, laboratory values, ECG presentation and therapy, but not regarding 28-day mortality. Moreover, typical comorbidities and risk factors (diabetes, hypertension, hyperlipidemia, smoking, impaired renal function) are associated with an increased risk of hospitalized reinfarction. Conversely, STEMI ECG, being married, German nationality and bypass surgery are predictors for a lower risk of hospitalized reinfarction. Incident AMI and reinfarction are distinctly different in many characteristics, which physicians should have in mind when treating patients with prior AMI. Typical comorbidities are risk factors for hospitalized reinfarction. This underlines the importance of comprehensive treatment of these comorbidities including education of patients and encouragement towards lifestyle adjustments.

Abstract
Study Objectives Timely coronary reperfusion is critical for favorable outcomes after ST‐elevation myocardial infarction (STEMI). A substantial proportion of the total ischemic time is patient related, occurring before first medical contact (FMC). We aimed to expand the limited current understanding of the associations between prehospital intervals and clinical outcomes. Methods We conducted a retrospective analysis of consecutive STEMI patients who underwent primary percutaneous coronary intervention (pPCI) (January 2009–March 2016) and assessed the associations between prehospital intervals and the incidence of new heart failure, cardiogenic shock, and hospital length of stay (LOS), adjusting for important clinical variables. Results A total of 773 patients (77% men, median age 65 years) met eligibility criteria. The median pre‐911 activation interval was 29 minutes (interquartile range: 11, 89); the median 911 call to FMC interval was 12 minutes (interquartile range: 9, 15). In multivariable analysis, there was a V‐shaped relationship between the pre‐911 activation interval and outcomes: a lower likelihood of new heart failure (odds ratio [OR] 0.51; 95% confidence interval [CI]: 0.30, 0.87), cardiogenic shock (OR 0.40; 95% CI: 0.21, 0.75) and prolonged LOS (OR 0.24; 95% CI: 0.14, 0.42) for midrange intervals (11–88 minutes) when compared to the early (< 11‐minute) interval. There was no statistically significant relationship between total pre‐FMC time and FMC to device activation time. Conclusions Among ambulance‐transported STEMI patients receiving pPCI, the shortest and longest pre‐911 activation time intervals were associated with poorer outcomes. However, variation in post‐FMC interval alone was not associated with outcomes, suggesting that interventions to reduce pre‐FMC intervals must be prioritized.

Abstract
PURPOSE Stable angina is ischemic chest pain on exertion or with emotional stress. Despite guideline-directed therapy, up to 30% of patients have suboptimal pain relief. The aims of this study were to: (1) determine the feasibility and acceptability of a randomized controlled trial (RCT) of acupuncture; and (2) evaluate preliminary efficacy of acupuncture with respect to reduction of pain and increased functional status and health-related quality of life (HRQoL). METHODS Participants with stable angina for ⩾1 month received either a standardized acupuncture protocol, twice per week for 5 weeks, or an attention control protocol. Measures included the McGill Pain Questionnaire (average pain intensity (API), pain now) and the Seattle Angina Questionnaire-7 (functional status, symptoms, and HRQoL). Feasibility was defined as ⩾80% recruitment, ⩾75% retention following enrollment, and ⩾80% completion. Descriptive statistics and mixed-effects linear regression were used for analysis. RESULTS The sample (n = 24) had a mean age of 59 ± 12 years, was predominantly female (63%), and represented minority groups (8% White, 52% Black, 33% Hispanic, and 8% Other). Feasibility was supported by 79% retention and 89% completion rates. The recruitment rate (68%) was slightly lower than expected. Acceptability scores were 87.9% for the acupuncture group and 51.7% for the control group. Outcomes were significantly better for the acupuncture versus control groups (API, b = -2.1 (1.1), p = 0.047; functional status, b = 27.6 (7.2), p < 0.001; and HRQoL, b = 38.8 (11.9), p = 0.001). CONCLUSIONS AND IMPLICATIONS Acupuncture was feasible and acceptable in our diverse sample. We were slightly under the recruitment target of 80%, but participants who started the study had a high likelihood of completing it. Acupuncture shows promise for stable angina, but its effectiveness needs to be confirmed by a larger, adequately powered RCT. TRIAL REGISTRATION NUMBER NCT02914834 (ClinicalTrials.gov).

Abstract
BACKGROUND Delay in seeking medical treatment for suspected acute coronary syndrome can lead to negative patient outcomes. OBJECTIVE Our aim was to evaluate the prevalence and predictors of delay in seeking care in high-risk chest pain patients with or without acute coronary syndrome (ACS). METHODS This was a secondary analysis of an observational cohort study of patients transported by Emergency Medical Services for a chief complaint of chest pain. Important demographic and clinical characteristics were extracted from electronic health records. Two independent reviewers adjudicated the presence of ACS. Logistic regression was used to model the predictors of delay in seeking care. RESULTS The final sample included 743 patients (99% non-Hispanic). Overall, 24% presented > 12 h from onset of symptoms. Among those with ACS (n = 115), 14% presented > 12 h after onset of symptoms. Race, smoking, diabetes, and related symptoms were associated with delayed seeking behavior. In multivariate analysis, non-Caucasian race (black or others) was the only independent predictor of > 12 h delay in seeking care (odds ratio 1.4; 95% confidence interval 1.0-1.9). CONCLUSIONS One in four patients with chest pain, including 14% of those with ACS, wait more than 12 h before seeking care. Compared to non-blacks, black patients are 40% more likely to delay seeking care > 12 h.

Abstract
An aneurysmal subarachnoid hemorrhage (aSAH) carries a high disability burden. The true impact of rurality as a predictor of outcome severity is unknown. Our aim is to clarify the relationship between the proposed explanations of regional and rural health disparities linked to severity of outcome following an aSAH. An initial literature search identified limited data directly linking geographical location, rurality, rural vulnerability, and aSAH. A further search noting parallels with ischemic stroke and acute myocardial infarct literature presented a number of diverse and interrelated predictors. This a priori knowledge informed the development of a conceptual framework that proposes the relationship between rurality and severity of outcome following an aSAH utilizing structural equation modeling. The presented conceptual framework explores a number of system, environmental, and modifiable risk factors. Socioeconomic characteristics, modifiable risk factors, and timely treatment that were identified as predictors of severity of outcome following an aSAH and within each of these defined predictors a number of contributing specific individual predictors are proposed. There are considerable gaps in the current knowledge pertaining to the impact of rurality on the severity of outcome following an aSAH. Absent from the literature is any investigation of the cumulative impact and multiplicity of risk factors associated with rurality. The proposed conceptual framework hypothesizes a number of relationships between both individual level and system level predictors, acknowledging that intervening predictors may mediate the effect of one variable on another.

Abstract
Early diagnosis is critical in the management of patients with acute coronary syndrome (ACS), particularly ST-elevation myocardial infarction (STEMI), because effective therapies are time-dependent. Aims of this secondary analysis were to determine: (i) the prognostic value of symptoms for an ACS diagnosis in conjunction with electrocardiographic (ECG) and troponin results; and (ii) if any of 13 symptoms were associated with prehospital delay in those presenting to the emergency department (ED) with potential ACS. Patients receiving a cardiac evaluation in the ED were eligible for the study. Thirteen patient-reported symptoms were assessed in triage. Prehospital delay time was calculated as the time from symptom onset until registration in the ED. A total of 1,064 patients were enrolled in five EDs. The sample was 62% male, 70% white, and had a mean age of 60.2 years. Of 474 participants diagnosed with ACS, 118 (25%) had STEMI; 251 (53%) had non-ST elevation myocardial infarction (NSTEMI); and 105 (22%) had unstable angina. Sweating (OR = 1.42 CI [1.01, 2.00]) and shoulder pain (OR = 1.64 CI [1.13, 2.38]) added to the predictive value of an ACS diagnosis when combined with ECG and troponin results. Shortness of breath (OR = 0.71 CI [0.50, 1.00]) and unusual fatigue (OR = 0.60 CI [0.42, 0.84]) were predictive of a non-ACS diagnosis. Sweating predicted shorter prehospital delay (HR = 1.35, CI [1.10, 1.67]); shortness of breath (HR = 0.73 CI [0.60, 0.89]) and unusual fatigue (HR = 0.72, CI [0.57, 0.90]) were associated with longer prehospital delay. Patient-reported symptoms are significantly associated with ACS diagnoses and prehospital delay. Sweating and shoulder pain combined with ECG signs of ischemia may improve the timely detection of ACS in the ED.

Abstract
Background A system of care designed to measure and improve process measures such as symptom recognition, emergency response, and hospital care has the potential to reduce mortality and improve quality of life for patients with ST-elevation myocardial infarction (STEMI). Objective To document the methodology and rationale for the implementation and impact measurement of the Heart Rescue India project on STEMI morbidity and mortality in Bangalore, India. Study Design A hub and spoke STEMI system of care comprised of two interventional, hub hospitals and five spoke hospitals will build and deploy a dedicated emergency response and transport system covering a 10 Km. radius area of Bangalore, India. High risk patients will receive a dedicated emergency response number to call for symptoms of heart attack. A dedicated operations center will use geo-tracking strategies to optimize response times including first responder motor scooter transport, equipped with ECG machines to transmit ECG's for immediate interpretation and optimal triage. At the same time, a dedicated ambulance will be deployed for transport of appropriate STEMI patients to a hub hospital while non-STEMI patients will be transported to spoke hospitals. To enhance patient recognition and initiation of therapy, school children will be trained in basic CPR and signs and symptom of chest pain. Hub hospitals will refine their emergency department and cardiac catheterization laboratory protocols using continuous quality improvement techniques to minimize treatment delays. Prior to hospital discharge, secondary prevention measures will be initiated to enhance long-term patient outcomes.

Abstract
BACKGROUND Tele-electrocardiography (tele-ECG) is a powerful ally in the screening of acute ischemic lesions. INTRODUCTION Evidence that confirms the correlation between the diagnosis of acute coronary syndrome (ACS) determined in the prehospital setting and the confirmation of the diagnosis in the hospital setting is scarce. This study compares the presumed diagnosis of ACS in the prehospital setting based on electrocardiographic changes, such as ST-segment deviation, with the diagnosis confirmed in a hospital setting. MATERIALS AND METHODS Retrospective, cross-sectional analysis of medical records of patients who sought emergency ambulance services of a distinguished public healthcare service in the city of Porto Alegre from September 2013 to August 2014. Data were collected from tele-ECG recordings and medical records available at the database of the Secretary of Health. The study was based on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. RESULTS Among the 1,338 prehospital examinations performed, a total of 250 admissions in tertiary hospitals were registered. There was a significant agreement (p < 0.01) of 71% of the electrocardiographic changes identified in the prehospital setting with the diagnosis of ACS confirmed in the hospital setting. These changes were more prevalent in men (p = 0.048) and in patients aged 60 years or older (p = 0.006). DISCUSSION The tele-ECG allows the early diagnosis of ACS, reducing the delay to definitive treatment, be it reperfusion, chemical, or mechanical therapy. CONCLUSIONS Seventy-two percent of the prehospital diagnosis of ACS based on electrocardiographic changes was later confirmed in the hospital setting.

Abstract
Background: Despite efforts aimed at reducing the prehospital delay and treatment delay, a considerable proportion of patients with ST elevation myocardial infarction (STEMI) present late and receive the reperfusion therapy after unacceptably long time periods. This study aimed at finding out the patients' decision delay, prehospital delay, door-to-electrocardiography (ECG), door-to-needle, and door-to-primary percutaneous coronary intervention (PCI) times and their determinants among STEMI patients. Materials and Methods: A cross-sectional study conducted among 96 patients with STEMI admitted in a tertiary care center in South India. The data were collected using interview of the patients and review of records. The distribution of the data was assessed using Kolmogorov–Smirnov test, and the comparisons of the patients' decision delay, prehospital delay, and time to start reperfusion therapy with the different variables were done using Mann–Whitney U-test or Kruskal–Wallis test based on the number of groups. Results: The mean (standard deviation) and median (range) age of the participants were 55 (11) years and 57 (51) years, respectively. The median patients' decision delay, prehospital delay, door-to-ECG, door-to-needle, and door-to-primary PCI times were 75, 290, 12, 75, 110 min, respectively. Significant factors associated (P < 0.05) with patients' decision delay were alcoholism, symptom progression, and attempt at symptom relief measures at home. Prehospital delay was significantly associated (P < 0.05) with domicile, difficulty in arranging money, prior consultation at study center, place of symptom onset, symptom interpretation, and mode of transportation. Conclusions: The prehospital delay time among the South Indian population is still unacceptably high. Public education, improving the systems of prehospital care, and measures to improve the patient flow and management in the emergency department are essentially required. The time taken to take ECG and to initiate reperfusion therapy in this study points to scope for improvement to meet the American Heart Association recommended timings.

Abstract
BACKGROUND AND OBJECTIVES A limited number of studies have examined the interaction between gender and age with regard to extent of prehospital delay. Our aim was to examine gender and age differences associated with prehospital delay in Chinese patients presenting with ST-elevation myocardial infarction (STEMI). METHODS A total of consecutive 1429 records from patients presenting with STEMI were analyzed between June 1, 2009, and June 1, 2010. We compared hospital care data by gender and age for inpatients with acute STEMI presenting within 24 hours of symptom onset. RESULTS The overall median duration of prehospital delay was 150 minutes (mean, 266 minutes). For patients 54 years or younger, 55 to 64 years old, and 75 years or older, women were more likely to experience longer delays compared with men (P < .05) even after controlling for medical history and risk factors. For male patients, compared with groups 54 years or younger, with the exception of men 55 to 64 years old, older male patients were more likely to have greater delays (P < .05) even after controlling for medical history and risk factors. However, after controlling for other variables, these gender and age differences in prehospital delay were no longer statistically significant. Among patients 65 to 74 years old, there were no gender differences in prehospital delay. Among female patients, there were no age differences in prehospital delay. CONCLUSIONS Male elderly patients (aged ≥65 years) and women (aged ≤64 and ≥75 years) with STEMI were more likely to delay seeking timely medical care. These gender and age differences were explained by different education, stable income, medical insurance, typical chest pain, and cognition toward heart diseases.

Abstract
OBJECTIVE To describe the profile of physicians working at the Prehospital Emergency Medical System (SAMU) in Brazil and to evaluate their quality of life. METHODS Both a semi-structured questionnaire with 57 questions and the SF-36 questionnaire were sent to research departments within SAMU in the Brazilian state capitals, the Federal District and inland towns in Brazil. RESULTS Of a total of 902 physicians, including 644 (71.4%) males, 533 (59.1%) were between 30 and 45 years of age and 562 (62.4%) worked in a state capital. Regarding education level, 45.1% had graduated less than five years before and only 43% were specialists recognized by the Brazilian Medical Association. Regarding training, 95% did not report any specific training for their work at SAMU. The main weaknesses identified were psychiatric care and surgical emergencies in 57.2 and 42.9% of cases, respectively; traumatic pediatric emergencies, 48.9%; and medical emergencies, 42.9%. As for procedure-related skills, the physicians reported difficulties in pediatric advanced support (62.4%), airway surgical access (45.6%), pericardiocentesis (64.4%) and thoracentesis (29.9%). Difficulties in using an artificial ventilator (43.3%) and in transcutaneous pacing (42.2%) were also reported. Higher percentages of young physicians, aged 25-30 years (26.7 vs 19.0%; p<0.01), worked exclusively in prehospital care (18.0 vs 7.7%; p<0.001), with workloads >48 h per week (12.8 vs 8.6%; p<0.001), and were non-specialists with the shortest length of service (<1 year) at SAMU (30.1 vs 18.2%; p<0.001) who were hired without having to pass public service exams (i.e., for a temporary job) (61.8 vs 46.2%; p<0.001). Regarding quality of life, the pain domain yielded the worst result among physicians at SAMU. CONCLUSIONS The doctors in this sample were young and within a few years of graduation, and they had no specific training in prehospital emergencies. Deficiencies were mostly found in pediatrics and psychiatry, with specific deficiencies in the handling of essential equipment and in the skills necessary to adequately attend to prehospital emergencies. A disrespectful labor scenario was also found; the evaluation of quality of life showed a notable presence of pain on the SF-36 among physicians at SAMU and especially among doctors who had worked for a longer length of time at SAMU.

Abstract
BACKGROUND Patients' treatment-seeking delay remains a significant barrier to timely initiation of reperfusion therapy. Measurement of treatment-seeking delay is central to the large body of research that has focused on pre-hospital delay (PHD), which is primarily patient-related. This research has aimed to quantify PHD and its effects on morbidity and mortality, identify contributing factors, and evaluate interventions to reduce such delay. A definite time of symptom onset in acute coronary syndrome (ACS) is essential for determining delay, but difficult to establish. This literature review aimed to explore the variety of operational definitions of both PHD and symptom onset in published research. METHODS AND RESULTS We reviewed the English-language literature from 1998-2013 for operational definitions of PHD and symptom onset. Of 626 papers of possible interest, 175 were deemed relevant. Ninety-seven percent reported a delay time and 84% provided an operational definition of PHD. Three definitions predominated: (a) symptom onset to decision to seek help (18%); (b) symptom onset to hospital arrival (67%), (c) total delay, incorporating two or more intervals (11%). Of those that measured delay, 8% provided a definition of which symptoms triggered the start of timing. CONCLUSION We found few and variable operational definitions of PHD, despite American College of Cardiology/American Heart Association recommendations to report specific intervals. Worryingly, definitions of symptom onset, the most elusive component of PHD to establish, are uncommon. We recommend that researchers (a) report two PHD delay intervals (onset to decision to seek care, and decision to seek care to hospital arrival), and (b) develop, validate and use a definition of symptom onset. This will increase clarity and confidence in the conclusions from, and comparisons within and between studies.

Abstract
OBJECTIVE Women delay seeking care for symptoms of acute coronary syndrome (ACS) because of atypical symptoms, perceptions of invulnerability, or keeping symptoms to themselves. The purpose of this study was to explore how women recognized and interpreted their symptoms and subsequently decided whether to seek treatment within the context of their lives. METHOD Grounded theory was used to provide the methodological basis for data generation and analysis. Data were collected using in-depth interviews with 9 women with ACS. RESULTS All participants went through a basic social process of searching for the meaning of their symptoms which informed their decisions about seeking care. Stages in the process included noticing symptoms, forming a symptom pattern, using a frame of reference, finding relief, and assigning causality. The evolving MI group (n = 5) experienced uncertainty about bodily cues, continued life as usual, until others moved them toward care. The immediately recognizable MI group (n = 4) labeled their condition quickly, yet delayed, as they prepared themselves and others for their departure. CONCLUSIONS All women delayed, regardless of their ability to correctly label their symptoms. Education aimed at symptom recognition/interpretation addresses only part of the problem. Women should also be educated about the potential danger of overestimating the time they have to seek medical attention.

Abstract
OBJECTIVES To investigate treatment-seeking delays in Chinese patients with acute myocardial infarction (AMI) and to compare sex differences in this behaviour. METHODS A descriptive cross-sectional study was undertaken in patients with AMI, admitted to one of three hospitals in Shanghai, China. A treatment-seeking behaviour questionnaire was administered to each patient within 48 h of hospital admission. RESULTS In total, 250 patients were included: 159 men and 91 women. The median time for patients with AMI to make a treatment-seeking decision was 130 min. Women took significantly longer to seek treatment than men (240 min versus 120 min). The majority of patients (70.8%) took >1 h to decide to seek treatment. The emergency medical service (EMS) was used by 77 (30.8%) of patients, and these patients had a significantly shorter prehospital delay time than those who transported themselves to hospital. Predictive factors for using the EMS were pain level and rating AMI symptoms as severe. CONCLUSIONS Chinese patients with AMI had a significant prehospital delay time and women took longer than men to seek treatment. Public awareness of the importance of seeking immediate medical assistance for AMI via the EMS needs to be increased in China.
