Write answer in between .Q:A 75-year-old woman presents to her physician with a cough and shortness of breath. She says that cough gets worse at night and her shortness of breath occurs with moderate exertion or when lying flat. She says these symptoms have been getting worse over the last 6 months. She mentions that she has to use 3 pillows while sleeping in order to relieve her symptoms. She denies any chest pain, chest tightness, or palpitations. Past medical history is significant for hypertension and diabetes mellitus type 2. Her medications are amiloride, glyburide, and metformin. Family history is significant for her father who also suffered diabetes mellitus type 2 before his death at 90 years old. The patient says she drinks alcohol occasionally but denies any smoking history. Her blood pressure is 13095 mm Hg, temperature is 36.5C 97.7F, and heart rate is 100min. On physical examination, she has a sustained apical impulse, a normal S1 and S2, and a loud S4 without murmurs. There are bilateral crackles present bilaterally. A chest radiograph shows a mildly enlarged cardiac silhouette. A transesophageal echocardiogram is performed and shows a normal left ventricular ejection fraction. Which of the following myocardial changes is most likely present in this patient?? A: Ventricular hypertrophy with sarcomeres duplicated in series, B: Macrophages with hemosiderin, C: Ventricular hypertrophy with sarcomeres duplicated in parallel, D: Asymmetric hypertrophy of the interventricular septum, E: Granuloma consisting of lymphocytes, plasma cells and macrophages surrounding necrotic,  <response>: This is a clinical vignette describing a 75-year-old woman with a chronic cough, shortness of breath, and symptoms that worsen when lying down. She has a history of hypertension and diabetes. On exam she has signs of heart failure including an S4, crackles, and cardiomegaly on CXR. An echocardiogram shows normal ejection fraction. The question is asking about myocardial changes that would explain her symptoms and exam findings. Based on the chronicity, cardiac enlargement, and heart failure symptoms, the most likely diagnosis is hypertensive heart disease leading to diastolic heart failure. Ventricular hypertrophy with sarcomeres duplicated in parallel is the type of myocardial change seen in pressure overload states like hypertension. The other choices describe changes seen in other conditions not supported by the vignette.C: Ventricular hypertrophy with sarcomeres duplicated in parallel
