Write answer in between .Q:A 63-year-old man undergoes workup for nocturnal dyspnea and what he describes as a choking sensation while sleeping. He also endorses fatigue and dyspnea on exertion. Physical exam reveals a normal S1, loud P2, and a neck circumference of 17 inches 43 cm normal 14 inches 35 cm. His temperature is 98.8F 37C, blood pressure is 12882 mmHg, pulse is 86min, and respirations are 19min. He undergoes spirometry, which is unrevealing, and polysomnography, which shows 16 hypopneic and apneic events per hour. Mean pulmonary arterial pressure is 30 mmHg. Which of the following complications is this patient most at risk for?? A: Aspiration pneumonia, B: Chronic obstructive pulmonary disease, C: Left ventricular failure, D: Pulmonary embolism, E: Right ventricular failure,  <response>: Based on the patients symptoms of nocturnal dyspnea, choking sensation while sleeping, fatigue, and dyspnea on exertion, as well as the physical exam findings of loud P2, increased neck circumference, and elevated mean pulmonary arterial pressure, this patient likely has obstructive sleep apnea. The polysomnography results confirming hypopneic and apneic events also support this diagnosis. Patients with untreated obstructive sleep apnea are at increased risk for developing pulmonary hypertension over time due to repetitive hypoxemia and intrathoracic pressure changes. This can lead to right ventricular failure.E: Right ventricular failure
