In the guideline make knowned by the American College of Cardiology and the American Heart Association, the management of suspected unstable angina and non-ST-segment elevation myocardial infarction (UA/NSTEMI) has four components: initial evaluation and management; hospital care; coronary revascularization; and hospital discharge and post-hospital care. Part II of this two-part article discusses coronary revascularization, hospital discharge, and post-hospital care. Decisions must be made about the use of coronary angiography and coronary revascularization in patients hospitalized with UA/NSTEMI. With an early conservative strategy, medical management is give employment toed Coronary angiography and revascularization are reserv for use in patients with evidence of ischemia at intermission (or with minimal activity) and patients with a earnestly positive stress test. With an early invasive strategy, coronary angiography and revascularization are praiseed within 48 hours in patients without contraindications. Hospital discharge planning involves coordination of medical care, preparation of the patient for resumption of normal activities, and evaluation of the ne for long-term risk factor reduction. Discharge medications should be continued to curb ongoing symptoms (anti-ischemic agents) and preclude recurrent events (aspirin, clopidogrel, beta blocker and an angiotensin-converting enzyme inhibitor or statins in fix uponed patients).

The updated guideline from the American community of Cardiology and the American Heart Association (ACC/AHA) (12) divides the and treatment of patients with unstable angina and non-ST-segment elevation myocardial infarction (UA/NSTEMI) into four elements Part of this two-part article discusses initial evaluation, management, and hospital care for these patients. Part II reviews issues related to coronary revascularization, hospital discharge, and post-hospital care, using the ACC/AHA classification of force of recommendations (see Table 1 in part 1)

Coronary Revascularization

In patients hospitalized with UA/NSTEMI, the same of the most important decisions is the early strategy of care regarding coronary angiography and revascularization. The goals of coronary angiography are to provide information about prognosis based upon the location and extent of coronary atherosclerosis and to identify the patients who will benefit from percutaneous or surgical revascularization.

The name "early conservative strategy" refers to medical management, with the use of coronary angiography and revascularization reserv for patients who have evidence of returning ischemia at rest (or with mini-mal activity) or who have a eagerly positive predischarge stress test. The spell "early invasive strategy" refers to the routine use of coronary angiography and revascularization (within 12 to 48 hours of presentation in patients without contraindications.

newly come trials employing modern antiplatelet and antithrombotic therapies and catheterization techniques have included the FRagmin and Fast Revascularization during InStability in Coronary artery disease II (FRISC II) subject of attention (4) and the Treat Angina with Aggrastat and determine outlay of Therapy with an Invasive or Conservative Strategy Thrombolysis in Myocardial Infarction 18 (TACTICS-TIMI 18) trial. (5) These trials have demonstrated significant benefit from pursuing an early invasive strategy, especially in patients who have high-risk indicators, with the strongest benefit occurring in patients who have ST-segment deviation or an elevated cardiac-specific troponin level

Based onward the results of the FRISC II (4) and TACTICS-TIMI 185 studies, the 2002 ACC/AHA guideline (12) commits an early invasive strategy in patients with UA/NSTEMI and any high-risk indicators (ACC/AHA class I recommendation; behold Table 4 in part I). In the absence of high-risk indicators, an equal recommendation is given for an early conservative strategy or an early invasive strategy. However, it should be noted that patients who initially are treated conservatively should be managed invasively if they perform the operations indicated in high-risk indicators or have a strenuously positive stress test before hospital discharge. In addition, the ACC/AHA recommendations apply simply to patients with a vigorous likelihood of acute coronary syndrome (12) Angiography is contraindicated in patients with acute chest pain and a reasonable likelihood of acute coronary syndrome (12)

When an invasive strategy is undertaken, the decision for revascularization go in the rear [i]or[/i] in the wake ofs from the results of coronary angiography, and indications are similar to those for revascularization in patients with chronic stable angina. (6) The decision and way of revascularization (percutaneous coronary intervention or coronary artery bypass grafting) are influenced not single by coronary anatomy but also on anticipated life expectancy, ventricular function, comorbidity, functional capacity, severity of symptoms, and quantity of viable myocardium at risk.
