Case 1 • 67 year old man • Presented with anterior wall MI in May. Underwent stent placement in the LAD. The other arteries were patent. • Echo demonstrated mildly-moderate decreased LV systolic function with anteroapical akinesis • Unremarkable recovery. Started on aspirin, plavix, simvastatin, atenolol 25mg and discharged home
November 1 • Acute onset of shortness of breath • Wife called Mada, • HR 94 BP 114/60 RR 28 sat 91% • Bibasilar crackles
Echo • Dilated LV with moderately-severely decreased function. • Anteroseptal and apical dyskinesis • Moderate-severe mitral regurgitation • Normal RV size and function • Mild pulmonary hypertension

Hospital Course • Admitted with a diagnosis of acute decompensated heart failure. • What is the first thing you do?
Comprehensive inhibition of neurohormonal activation • achieve euvolemia with diuretics and salt restriction • ACE-inhibitors • Beta-blockers (so far only carvedilol, bisoprolol and extended release metoprolol) • Careful spironolactone

If... • If the patient cannot tolerate ACE-inhibitor, ARB may be substituted (valsartan) • If the patient cannot tolerate beta blocker, ACE-I and ARB may be combined • Isosorbide and hydralazine can be considered in patients who cannot tolerate ACE-I
Now what should we do? • A. Cardiac catheterization to see if the stent is patent • B. Stress thallium to see if there is residual ischemia • C. Exercise echo to see if the mitral regurgitation and pulmonary hypertension worsen with exercise • D. Transesophageal echo to determine severity of mitral regurgitation
Other considerations • A. Put in a defibrillator • B. Put in a pacemaker to allow for target doses of beta blocker • C. Put in a biventricular pacemaker • D. Add amiodarone for the prevention of sudden cardiac death

Diastolic CHF – Goals of Therapy • Reduce preload • Decrease heart rate • Normalize blood pressure • Maintain atrial contraction • Improve relaxation • Cause regression of LVH • Decrease interstitial fibrosis • Treat ischemia • Decrease neurohumoral activation
In the ER • The patient was given IV beta blocker and digoxin, with slowing of his heart rate to the 80s. • Echo demonstrated : • Dilated atria • Normal LV chamber size with mild hypertrophy. Normal RV size and function • Normally functioning aortic prosthesis • Mild-moderate mitral regurgitation • Mild pulmonary hypertension
What do you do now? • A. Begin anticoagulation, and plan to cardiovert the patient in 3 weeks • B. Begin anticoagulation and plan for TEE cardioversion in the next few days • C. Begin anticoagulation, and initiate amiodarone therapy in preparation for cardioversion • D. Give digoxin in order to lead to spontaneous cardioversion
