Y1 - 2018 N1 - T2 - Color Atlas and Synopsis of Heart Failure AB - A 55-year-old woman presented to your clinic for a follow-up. She was diagnosed with nonischemic cardiomyopathy diagnosed9 months ago after she presented to the emergency department (ED) with New York Heart Association (NYHA) class IV heart failure (HF) symptoms. Coronary angiography then revealed no obstructive coronary artery disease (CAD). Echocardiogram at the time of her initial evaluation revealed moderately dilated left ventricle, and global hypokinesis with an ejection fraction of 20%, with no gross valvular abnormalities. Cardiac magnetic resonance imaging (MRI) showed midwall fibrosis consistent with nonischemic cardiomyopathy. During her clinic visit, she reported symptoms of effort intolerance and exertional dyspnea with mild exertion. She denied resting or exertional chest pain. An echocardiogram at the time of her visit showed left ventricular ejection fraction (LVEF) of 25%. Her current medications include carvedilol 25 mg twice daily, lisinopril 10 mg twice daily, aldactone 25 mg by mouth once a day, Lipitor 80 mg by mouth once daily, Aspirin (ASA) 81 mg by mouth once daily, and Plavix 75 mg by mouth once daily. Electrocardiogram showed normal sinus rhythm, left bundle branch block with QRS duration of 155 ms. Blood Pressure is 90/60 mm Hg and heart rate is 70 beats per minute. Her cardiovascular examination was unremarkable. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/18 UR - accesscardiology.mhmedical.com/content.aspx?aid=1161018447 ER -
