Final answer:
Urgent surgical intervention is the best approach to reduce the risk of postoperative organ and neurologic deficits in a patient with an acute type A aortic dissection and a history of CAD.
Step-by-step explanation:
In a patient with an acute type A aortic dissection and a history of coronary artery disease (CAD), the best approach to reduce the risk of postoperative organ and neurologic deficits would be urgent surgical intervention. While administration of aspirin, intravenous fluid resuscitation, and blood pressure control with antihypertensive medications are important considerations in managing cardiovascular disease, they are not the primary interventions to address the immediate and life-threatening issue of an aortic dissection. Urgent surgical repair is critical for survival and to prevent further complications, including organ and neurologic deficits. It is also important to note that long-term management may involve lifestyle changes, regular exercise, a diet low in sodium and saturated fats, and medications to handle underlying risk factors such as hypertension and cholesterol.
