Activation of emergency medical services (EMS) is critical for the early triage and treatment of patients experiencing ST-segment-elevation myocardial infarction, yet data regarding EMS use and its association with subsequent clinical care are limited.
We performed an observational analysis of 37 634 ST-segment-elevation myocardial infarction patients treated at 372 US hospitals participating in the National Cardiovascular Data Registry Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With the Guidelines between January 2007 and September 2009, and examined independent patient factors associated with EMS transportation versus patient self-transportation. We found that EMS transport was used in only 60% of ST-segment-elevation myocardial infarction patients. Older patients, those living farther from the hospital, and those with hemodynamic compromise were more likely to use EMS transport. In contrast, race, income, and education level did not appear to be associated with the mode of transport. Compared with self-transported patients, EMS-transported patients had significantly shorter delays in both symptom-onset-to-arrival time (median, 89 versus 120 minutes; P<0.0001) and door-to-reperfusion time (median door-to-balloon time, 63 versus 76 minutes; P<0.0001; median door-to-needle time, 23 versus 29 minutes; P<0.0001).
Emergency medical services transportation to the hospital is underused among contemporary ST-segment-elevation myocardial infarction patients. Nevertheless, use of EMS transportation is associated with substantial reductions in ischemic time and treatment delays. Community education efforts are needed to improve the use of emergency transport as part of system-wide strategies to improve ST-segment-elevation myocardial infarction reperfusion care.

- "f EMS in the 2nd National Registry of Myocardial Infarction, which was conducted between June 1994 and March 1998 in the United States; this rate increased only to 60% a decade later as was documented in the National Cardiovascular Data Registry Acute Coronary Treatment and Intervention Outcomes Network Registry–Get With the Guidelines (2007–2009).
Nevertheless it is much higher than that demonstrated in our two registries. We also observed that the frequency of EMS utilization was similarly low in patients presenting with ST-segment elevation myocardial infarction (18%) and non-ST elevation ACS (17%). Moreover, the utilization of EMS was low among patients presenting with typical"

ABSTRACT: Acute coronary syndrome (ACS) represents one of the most common causes of death worldwide. Several practice guidelines have been developed in Europe and North America to improve outcome of ACS patients through implementation of the recommendations into clinical practice. It is well know that there is wide gap between guidelines and implementation in real practice as was demonstrated in registry findings mainly conducted in the developed world. Here in we review main gaps in the management of ACS patients observed from two recent registries conducted in the Middle East.

ABSTRACT: Non-ST elevation acute coronary syndromes are responsible for approximately 1 million admissions to U.S. hospitals and twice as many to European hospitals each year. Thus, they are among the most common serious illnesses in adults, and are associated with an in-hospital mortality of approximately 5%. The most common cause is rupture of an atherosclerotic coronary plaque, resulting in subtotal coronary occlusion. Diagnosis is based on the clinical picture of retrosternal chest pain, aided by electrocardiographic findings of ST segment deviations and biomarker abnormalities (elevation of troponin and natriuretic peptides) and cardiac imaging (myocardial scans showing perfusion defects). Treatment involves antiischemic agents (nitrates and β blockers), antiplatelet drugs (aspirin, P2Y(12), and glycoprotein IIb/IIIa receptor blockers), and anticoagulants (unfractionated and low-molecular-weight heparins). Patients should undergo risk stratification, and those with high-risk factors should undergo coronary arteriography promptly with the intent to carry out coronary revascularization. Those at low risk should continue to receive intensive antiischemic and antithrombotic therapy. At discharge, patients should receive intensive lipid-lowering therapy with high doses of a statin, as tolerated.

ABSTRACT: Little is known about the impact of thrombolytic agents on in-hospital outcomes in the Middle East. The objective of this study was to evaluate the impact of thrombolytic agents on in-hospital outcomes in ST-segment elevation myocardial infarction (STEMI) patients in six Middle Eastern countries. Gulf Registry of Acute Coronary Events was a prospective, multinational, multicentre, observational survey of consecutive acute coronary syndrome patients admitted to 65 hospitals in 2006 and 2007. Out of 1,765 STEMI patients admitted to hospitals within 12 h of symptoms onset, 25, 43, and 30% were treated with streptokinase, reteplase, and tenecteplase, respectively. Median age of the study cohort was 50 (45-59) years and majority were males (89%). The overall median symptom onset-to-presentation and median door-to-needle times were 130 min (65-240) and 45 min (30-75), respectively. Streptokinase patients had worse GRACE risk scores compared to patients who received fibrin specific thrombolytics. Academic hospitals and cardiologists as admitting physicians were associated with the use of fibrin specific thrombolytics. After significant covariate adjustment, both reteplase [odds ratio (OR), 0.38; 95% CI: 0.18-0.79; P = 0.009] and tenecteplase (OR, 0.30; 95% CI: 0.12-0.77; P = 0.012) were associated with lower all-cause in-hospital mortality compared with streptokinase. No significant differences in other in-hospital outcomes were noted between the thrombolytic agents. In conclusion, in light of the study's limitations, fibrin specific agents, reteplase and tenecteplase, were associated with lower all-cause in-hospital mortality compared to the non-specific fibrin agent, streptokinase. However, the type of thrombolytic agent used did not influence other in-hospital outcomes.
