Treating non-ST-segment elevation ACS. Pros and cons of current strategies

NSTE-ACS is a complex clinical event characterized by a variable degree of myocardial ischemia and triggered, in most patients, by a rupture of a vulnerable plaque that leads to acute intraluminal nonocclusive thrombosis. Traditionally, acute management strategies for NSTE-ACS have been aimed at identification of vascular areas with discrete atheroma and revascularization of the affected myocardium. Studies that have evaluated invasive strategies in NSTE-ACS suggest that the rates of hard clinical events are similar for both intensive medical treatment and early invasive management strategies. As shown recently in the Cooperative Cardiovascular Project study, intensive therapy with beta-blockers appears to be a viable management option that has comparable outcomes in most patients with NSTE-ACS. Although several different treatment strategies have been advocated in the management of NSTE-ACS, the available evidence-based information does not fully support some of these traditional approaches. Future prospective, well-controlled trials are needed to fully ascertain the role of invasive and other medical management strategies in patients with NSTE-ACS. Long-term aggressive management of established risk factors for CAD is unquestionably the most prudent and cost-effective therapeutic approach in the long-term management in patients recovering from NSTE-ACS.
