history is significant for right knee osteoarthritis He takes naproxen occasionally, to relieve knee pain.
He does not smoke or consume alcohol His BP is 165/75 mm Hg and PR is 70/min. The physical
examination showed a mild systolic ejection type murmur at the base of the heat to the right. An E-
KG revealed left ventricular hypertrophy and secondary ST segment and T wave change Moderate
left ventricular hypertrophy, without any flow abnormalities, was demonstrated on echocardiography.
The ejection fraction was 60%. What is the most probable cause of hypertension in this patient?

B. Elevated plasma renin activity
C. Aortic insufficiency
D. Increased cardiac output
E. Increased intravascular volume
2. A 32-year-old Caucasian female comes to the physician because of a one-week history of fatigue,
progressive worsening of shortness of breath and swelling of feet. She denies any chest pain She has

are 20/min Bilateral basal crackles, elevated jugular venous pressure, and 2+ bilateral pitting edema
of the ankles are noted Complete blood count is unremarkable. Transthoracic echocardiogram of her
heat will most likely show?
A. Concentric hypertrophy of the heart
