RESUMEN

INTRODUCTION: In the Indian subcontinent and Arab Gulf, coronary artery disease is affecting younger persons at greater rates. Few studies have focused on young ST-elevation myocardial infarction (STEMI) patients in these regions. We examine the clinical profile and treatment of STEMI patients aged <40 years. METHODS: Participants consisted of 77 STEMI patients, aged <40 years, admitted to hospitals in Abu Dhabi. Data were collected using electronic medical records. Descriptive statistics were calculated for STEMI profile, medical history, risk factors, in-hospital events, and treatment. RESULTS: Smoking was prevalent (61.0%). Beta blockers were frequently prescribed (90.7%); aspirin infrequently (12%). Of patients without history of each condition, 36.7% were diagnosed in-hospital with hypertension, 28.6% with elevated low-density lipoprotein, and 18.8% with lowered high-density lipoprotein. CONCLUSIONS: Among young adults who use tobacco, there is a need for improved screening for risk factors. Earlier detection and treatment of dyslipidemia and hypertension could prevent acute cardiac events among individuals aged <40 years with multiple risk factors.

RESUMEN

INTRODUCTION: The purpose of this multicenter study was to assess differences in demographics, medical history, treatment times, and follow-up status among patients with ST-elevation myocardial infarction (STEMI), who were transported to the hospital by emergency medical services (EMS) or by private vehicle, or were transferred from other medical facilities. METHODS: This multicenter study involved the collection of both retrospective and prospective data from 455 patients admitted to four hospitals in Abu Dhabi. We collected electronic medical records from EMS and hospitals, and conducted interviews with patients in person or via telephone. Chi-square tests and Kruskal-Wallis tests were used to examine differences in variables by mode of transportation. RESULTS: Results indicated significant differences in modes of transportation when considering symptom-onset-to-balloon time (p < 0.001), door-to-balloon time (p < 0.001), and health status at six-month and one-year follow-up (p < 0.001). Median times (interquartile range) for patients transported by EMS, private vehicle, or transferred from an outside facility were as follows: symptom-onset-to-balloon time in hours, 3.1 (1.8-4.3), 3.2 (2.1-5.3), and 4.5 (3.0-7.5), respectively; door-to-balloon time in minutes, 70 (48-78), 81 (64-105), and 62 (46-77), respectively. In all cases, EMS transportation was associated with a shorter time to treatment than other modes of transportation. However, the EMS group experienced greater rates of in-hospital events, including cardiac arrest and mortality, than the private transport group. CONCLUSION: Our results contribute data supporting EMS transportation for patients with acute coronary syndrome. Although a lack of follow-up data made it difficult to draw conclusions about long-term outcomes, our findings clearly indicate that EMS transportation can speed time to treatment, including time to balloon inflation, potentially reducing readmission and adverse events. We conclude that future efforts should focus on encouraging the use of EMS and improving transfer practices. Such efforts could improve outcomes for patients presenting with STEMI.

RESUMEN

INTRODUCTION: Physician perceptions about emergency medical services (EMS) are important determinants of improving pre-hospital care for cardiac emergencies. No data exist on physician attitudes towards EMS care of patients with ST-Elevation Myocardial Infarction (STEMI) in the Emirate of Abu Dhabi. OBJECTIVES: To describe the perceptions towards EMS among physicians caring for patients with STEMI in Abu Dhabi. METHODS: We surveyed a convenience sample of physicians involved in the care of patients with STEMI (emergency medicine, cardiology, cardiothoracic surgery and intensive care) in four government facilities with 24/7 Primary PCI in the Emirate of Abu Dhabi. Surveys were distributed using dedicated email links, and used 5-point Likert scales to assess perceptions and attitudes to EMS. RESULTS: Of 106 physician respondents, most were male (82%), practicing in emergency medicine (47%) or cardiology (44%) and the majority (63%) had been in practice for >10 years. Less than half of the responders (42%) were "Somewhat Satisfied" (35%) or "Very Satisfied" (7%) with current EMS level of care for STEMI patients. Most respondents were "Very Likely" (67%) to advise a patient with a cardiac emergency to use EMS, but only 39% felt the same for themselves or their family. Most responders were supportive (i.e. "Strongly Agree") of the following steps to improve EMS care: 12-lead ECG and telemetry to ED by EMS (69%), EMS triage of STEMI to PCI facilities (65%), and activation of PCI teams by EMS (58%). Only 19% were supportive of pre-hospital fibrinolytics by EMS. There were no significant differences in the responses among the specialties. CONCLUSIONS: Most physicians involved in STEMI care in Abu Dhabi are very likely to advise patients to use EMS for a cardiac emergency, but less likely to do so for themselves or their families. Different specialties had concordant opinions regarding steps to improve pre-hospital EMS care for STEMI.
