"2014 AHA/ACC Guideline for the Management of Patients With Non-ST-Elevation Acute Coronary Syndromes: A Report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines". Circulation. Published online September 23, 2014 (25): 2354–2394. doi: 10.1161/cir.0000000000000133. PMID 25249586
Door-to-balloon is a time measurement in emergency cardiac care (ECC), specifically in the treatment of ST segment elevation myocardial infarction (or STEMI). The interval starts with the patient's arrival in the emergency department, and ends when a catheter guidewire crosses the culprit lesion in the cardiac cath lab.
Acute coronary syndrome is subdivided in three scenarios depending primarily on the presence of electrocardiogram (ECG) changes and blood test results (a change in cardiac biomarkers such as troponin levels): [4] ST elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), or unstable angina.

As early as the 1980s, the college partnered with the American Heart Association to develop the first clinical practice guidelines for cardiovascular practice. In the 1990s, the college used the guidelines to lay the groundwork for studies documenting discrepancies best and actual cardiovascular practices.

The American Heart Association (AHA) is a nonprofit organization in the United States that funds cardiovascular medical research, educates consumers on healthy living and fosters appropriate cardiac care in an effort to reduce disability and deaths caused by cardiovascular disease and stroke.
Emergency bypass surgery for the treatment of an acute myocardial infarction (MI) is less common than PCI or thrombolysis. From 1995 to 2004, the percentage of people with cardiogenic shock treated with primary PCI rose from 27.4% to 54.4%, while the increase in coronary artery bypass graft surgery (CABG) was only from 2.1% to 3.2%.

Unstable angina is a type of angina pectoris [1] that is irregular or more easily provoked. [2] It is classified as a type of acute coronary syndrome. [3]It can be difficult to distinguish unstable angina from non-ST elevation (non-Q wave) myocardial infarction.
