A 70-year-old woman presents with heavy, crushing chest pain of 3-hour duration.  The pain is exacerbated with exertion and resolves with rest.  Past medical history is significant for type 2 diabetes.  She has a 40-year history of smoking (2 packs per week).  Current medications are metformin and canaglifozin (SGLT2 inhibitor) for management of her diabetes. Physical examination reveals an overweight individual with blood pressure 145/92 mm/Hg.  The remainder of the examination is within normal limits.  Laboratory studies are significant for severely depressed circulating HDL, increased total cholesterol and LDL, and mildly elevated triglycerides. ECG reveals T wave inversion, and serum Troponin is within the reference range.  A full workup confirms a diagnosis of acute coronary syndrome. 11. Which of the following is the strongest risk factor for this patient’s illness?

Calcium phosphate Ca3(PO4)2 is a mineral found in human bones and teeth.  Calcium phosphate has __________ oxygen atom(s) in every formula unit.

A 55-year old man is being evaluated by a cardiologist for exertional angina and dyspnea.  Past medical history is significant for poorly-controlled hypertension. Current medications are hydrochlorothiazide and Lisinopril (an ACE inhibitor). On physical examination, he is afebrile, blood pressure is 150/95 mm Hg, pulse is 90/min, and respiration rate is 16/min.  Auscultation of the chest demonstrates a late-peaking systolic murmur at the upper sternal border and delayed carotid pulses.  The lungs are clear.  Laboratory studies are within normal limits, including troponin. The ECG reveals mild left ventricular hypertrophy, which is confirmed by echocardiography. 13. Which of the following is the most likely diagnosis?
