Abstract
Background ST-elevation myocardial infarction (STEMI) requires swift intervention, with primary percutaneous coronary intervention (PCI) being essential to limit myocardial damage. The key factor affecting PCI effectiveness is the door-to-balloon (DTB) time. This observational study evaluated DTB times in STEMI patients at a tertiary care center who underwent primary angioplasty, examining adherence to benchmarks and identifying factors contributing to delays. Methodology This prospective observational study was conducted from March 2017 to August 2018 at Fortis Hospital Mulund, Mumbai, India. It included 171 STEMI patients aged 18 and older who underwent primary angioplasty. Patients with non-ST elevation myocardial infarction (NSTEMI), those who received thrombolysis, or had medical contraindications to primary angioplasty were excluded. Data on key time intervals were collected via direct observation and then analyzed using SPSS for Windows, Version 15 (Released 2006; SPSS Inc., Chicago, United States). Qualitative data were summarized using frequency and percentages, whereas quantitative data were presented as mean (±SD). T-test was applied to compare the mean duration between the two groups, i.e., DTB time ≤90 minutes and DTB time >90 minutes, and a p-value <0.05 was considered statistically significant. Results The participants had a mean age of 56.5 (±13.1) years and were predominantly male (78.4%). The mean DTB time was 70.21 (±29.16) minutes, with 79.5% achieving ≤90 minutes. Patient-related delays (48.6%) were mainly due to consent issues (31.4%), which was the most predominant cause. Hospital-related delays (51.4%) included catheterization laboratory occupancy (14.3%) and diagnostic delays (14.3%). Patients with DTB times >90 minutes had significantly longer durations in all procedural steps except door-to-ECG time. Conclusion This study underscores the complex challenges in achieving timely DTB times for STEMI patients undergoing primary angioplasty. Overcoming these barriers through targeted interventions is essential for optimizing management and enhancing outcomes. Insights into delay factors inform evidence-based strategies to improve the timeliness and effectiveness of STEMI care delivery.

[PMID: 37122000 PMCID: PMC10149151 DOI: 10.1186/s12245-023-00503-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Accepted: 04/02/2023] [Indexed: 05/02/2023] Open
Abstract
BACKGROUND Acute myocardial infarction (AMI) is the top cause of death in Maldives. Our study aims to determine the prehospital delay and its associated factors in AMI patients in Maldives. METHODS A cross-sectional study was conducted with 127 patients, divided into early (≤ 6 h) and delayed (> 6 h) presenters to the hospital. The data collection for the study was carried out by interviewing AMI patients, focusing on their socio-demographic characteristics, coronary artery disease risk factors, clinical symptoms, situational factors, and behavioral and cognitive responses to symptoms. RESULTS The median onset-to-door time was 230 (IQR 420) minutes. The mean age of AMI patients was 50.9 (SD ± 12.9) years old, and 39.4% of them had delayed presentation to the hospital. Smokers (adj OR = 0.3; 95% CI: 0.1, 0.9; P = 0.047) and those with previous episodes of chest pain or AMI (adj OR = 0.2; 95% CI: 0.03, 0.91; P = 0.038) were significant factors for early presentation to the hospital, while denial of symptoms (adj OR = 29.3; 95% CI: 1.6, 547.2; P = 0.024) and lack of knowledge (adj OR = 7.2; 95% CI: 1.77, 29.43; P = 0.006) led to a delayed decision to seek treatment. Situational factors such as onset at the workplace (adj OR = 5.8; 95% CI: 1.24, 26.83; P = 0.025) had lower odds of delay, whereas referral cases (adj OR = 7.7; 95% CI: 1.9, 30.94; P = 0.004) and use of sea ambulance (adj OR = 11.1; 95% CI: 2.8, 43.8; P = 0.001) were prone to delay in presentation to the hospital. CONCLUSION Sea ambulance, referral cases, lack of knowledge, and denial of symptoms are significant factors associated with prehospital delay among patients with AMI. Public awareness about the benefits of early presentation and improvement of the means of transportation between islands is suggested to improve emergency cardiac care in the country.

Abstract
Background Various Indian registries have documented a delay of more than five hours for acute coronary syndrome patients from onset of symptoms to reaching thrombolysis-enabled centres. We conducted this study to evaluate the factors responsible for pre-hospital delay in acute coronary syndrome patients. Methods This was a descriptive cross-sectional study conducted in consecutive acute coronary syndrome patients who reported to the tertiary care medical centre in North India. A standardized tool was used to record the demographic data, socioeconomic status and clinical presentation of patients. All factors which led to pre-hospital delay were noted and the appropriate statistical tests were used for analysis. Results A total of 130 patients (males=93, females=37) were included in the study. The median time at which the acute coronary syndrome patients presented to the thrombolysis and percutaneous coronary intervention enabled centre was 490 minutes (range: 20 - 810 minutes) and 710 minutes (range: 45 - 940 minutes) respectively. The various factors responsible for prehospital delay were rural residence (p-value <0.0001), visit to local dispensary (p-value=0.0023), delay in getting transport (p-value=0.03) and misinterpretation of cardiac symptoms (p-value=0.0004). A significant but weak negative correlation was found between per capita income, decision making time and time taken to receive thrombolytic therapy. Out of a total of 83 ST-elevation myocardial infarction patients, only 46 (51.80%) were thrombolysed. Though 69/83 (83.13%) ST-elevation myocardial infarction patients reached thrombolysis enabled centre directly, only nine (10.84%) were thrombolysed at first medical contact; the rest were transferred to the percutaneous coronary intervention-enabled centre without any prior information. Conclusion Our study concludes that besides socioeconomic and demographic variables, lack of public awareness, well established public transport & health insurance system lead to significant pre-hospital delays and increase the time to revascularization. Besides, judgemental error on the part of medical practitioners in the peripheries also significantly delays thrombolysis in ST-elevation myocardial infarction patients.

Abstract
Objective This study aimed to assess the duration of pre-hospital delay among ST-Segment Elevation Myocardial Infarction (STEMI) patients and its contributing factors. Methodology A cross-sectional study was conducted at Rural Satellite Center in Larkana, Pakistan from May to September 2020. A total of 240 STEMI patients who underwent primary percutaneous coronary intervention (P-PCI) were included. The patients' demographic characteristics, index event characteristics, mode of transportation, misinterpretations, misdiagnoses, and financial problems were recorded. Data were analyzed using SPSS version 22.0 (IBM Corp., Armonk, NY, USA). Results The observed pre-hospital time was 120 minutes; 229 (median; interquartile range [IQR]). It was found that 33.3% of patients arrived within one hour of the symptom onset, while 20.4% of patients delayed hospital arrival for more than six hours. The delay rate was highest among patients aged 41 to 65 years. Moreover, delayed admissions were more common among females as compared to males (p=0.008). Among the causes of delay in hospital arrival were misinterpretation, misdiagnosis, and transportation and financial issues. Of these, misdiagnosis significantly influenced the delay rate, i.e., more than 50% of the misdiagnosed patients arrived hospital after six hours of symptom onset (p<0.05). Conclusion The P-PCI rural satellite center had a positive impact as the observed pre-hospital delay rate was considerably less as compared to that reported in the existing literature. Moreover, the confounding factors were misdiagnosis and misinterpretations. We need to develop the concept of immediate appropriate help-seeking among patients.

Prevalence and Predictors of Delay in Seeking Emergency Care in Patients Who Call 9-1-1 for Chest Pain. J Emerg Med 2019; 57:603-610. [PMID: 31615705 DOI: 10.1016/j.jemermed.2019.07.012] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2019] [Revised: 07/02/2019] [Accepted: 07/11/2019] [Indexed: 12/31/2022]
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
Background In ST-elevation myocardial infarction (STEMI), prehospital delay is a significant factor, decreasing likelihood of revascularization and increasing mortality. Prehospital delays are substantive in Indian patients with STEMI. Our study aimed to investigate factors associated with prehospital delay in patients with STEMI. Methods A multicentric prospective analysis was conducted at five major cardiac care referral centers in Punjab including a tertiary care teaching hospital over a period of 1 year from January 2015 to December 2015. Patients presenting with STEMI were included in the study. A structured questionnaire was used to gather patient characteristics and factors responsible for prehospital delay. Results Of the 619 patients included in the study, 42% presented with more than 6 h of prehospital delay. On univariate analysis, delay was significantly higher among elderly (p = 0.01), illiterate patients (p = 0.02), and patients residing in rural areas (p = 0.04). Recognizing symptoms as cardiac in origin (p < 0.001), hospital as initial medical contact, and availability of prehospital electrocardiogram (ECG) (p = 0.001) were associated with shorter delays. On multivariate analysis, prehospital delay was significant in elderly patients, initial point of care as outpatient clinic, and patients without access to prehospital ECG. Conclusion Our study concludes that demographic and socioeconomic barriers exist that impede rapid care seeking and highlights the need for utilization of prehospital ECG to decrease prehospital delay. Possibilities include, educating the public on the importance of early emergency medical services contact or creating emergency stations in rural areas with ECG capabilities. Our study also invites further research, regarding role of telemedicine to triage patients derived from prehospital ECGs to decrease prehospital delay.

Abstract
Most patients with acute myocardial infarction (AMI) experience more than one symptom at onset. Although symptoms are an important early indicator, patients and physicians may have difficulty interpreting symptoms and detecting AMI at an early stage. This study aimed to identify symptom clusters among Korean patients with ST-elevation myocardial infarction (STEMI), to examine the relationship between symptom clusters and patient-related variables, and to investigate the influence of symptom clusters on treatment time delay (decision time [DT], onset-to-balloon time [OTB]). This was a prospective multicenter study with a descriptive design that used face-to-face interviews. A total of 342 patients with STEMI were included in this study. To identify symptom clusters, two-step cluster analysis was performed using SPSS software. Multinomial logistic regression to explore factors related to each cluster and multiple logistic regression to determine the effect of symptom clusters on treatment time delay were conducted. Three symptom clusters were identified: cluster 1 (classic MI; characterized by chest pain); cluster 2 (stress symptoms; sweating and chest pain); and cluster 3 (multiple symptoms; dizziness, sweating, chest pain, weakness, and dyspnea). Compared with patients in clusters 2 and 3, those in cluster 1 were more likely to have diabetes or prior MI. Patients in clusters 2 and 3, who predominantly showed other symptoms in addition to chest pain, had a significantly shorter DT and OTB than those in cluster 1. In conclusion, to decrease treatment time delay, it seems important that patients and clinicians recognize symptom clusters, rather than relying on chest pain alone. Further research is necessary to translate our findings into clinical practice and to improve patient education and public education campaigns.
