He describes the pain as tearing in nature. Medical history is positive for essential hypertension for 11 years. The patient has smoked 1015 cigarettes daily for the past 30 years. His temperature is 36.6C 97.8F, the heart rate is 107min, and the blood pressure is 17986 mm Hg in the right arm and 15772 mm Hg in the left arm. CT scan of the chest shows an intimal flap limited to the descending thoracic aorta. Which of the following best describes the most likely predisposing factor for this condition?? A: Abnormal elastic properties of the aorta, B: Coronary atherosclerosis, C: Aortic coarctation, D: Aortic atherosclerosis, E: Hypertensive urgency,  <response>: This is a clinical vignette describing a 59-year-old man with sudden onset of severe tearing chest pain between the shoulder blades. Key findings include longstanding hypertension, smoking history, asymmetric blood pressures in the arms, and a CT scan showing an intimal flap in the descending thoracic aorta. The question asks about the most likely predisposing factor for this condition. Based on the description, this patient most likely has an acute aortic dissection. The most common predisposing factor for aortic dissection is hypertension, which chronically injures the aortic wall. Smoking is also a risk factor. The asymmetric blood pressures and intimal flap on CT confirm the diagnosis.Choices A and E relate to hypertension but are less specific than choice D. Choices B and C are not predisposing factors for aortic dissection.D: Aortic atherosclerosis
