Initial approach to the patient who has chest pain.

The last decade has seen extraordinary advances in the cardiovascular arena, particularly in the evaluation and management of the patient who has acute coronary syndromes. From bedside markers of myocardial damage to drug-eluting stents, technical advances are proliferating. Efforts in developing an international registry for acute aortic dissection have helped elucidate the acute presentation, management, and prognosis of this uncommon but lethal disease. Finally, the multiple research efforts in coordinating clinical decision-making with serologic markers and advanced imaging for the diagnosis of pulmonary embolism is changing the approach to the patient at risk for thromboembolic disease.
