3 Case description Mr D. 69 years is referred to the emergency unit of your hospital for severe dyspnoea. Symptoms worsened progressively the week before admission. Hx: Dilated cardiomyopathy discovered 6 years ago. Most recent evaluation 1 year ago: NYHA II.. ECG : sinus rhythm 85 bpm. QRS duration:90msec Echo doppler: diffuse hypokinesia.lvef=23%. LVEDD = 69mm. Treatment: furosemide 40mg od/ Ramipril 5mg od/ carvedilol l 12.5 mg bid.

5 Recent Hx: Clinical Case Since he felt tired, he stopped all his medications four days ago and had several diners in gastronomic restaurants (French cuisine!!) Physical examination: Weight: 76kgs (+4) Height: 168 cms HR = 85 bpm Rhythm regular. BP: 105/70 mm Hg Bilateral diffuse pulmonary crackles. S3 gallop. Bilateral l foot and ankle edema.

6 Clinical Case ECG: sinus rhythm 100 bpm QRS = 90msec X ray: CTR = Diffuse bilateral pulmonary edema Biology : Na + = 138meq/l. K + = 3.9 meq/l. S creatinine = 139 μm/l. Sa O 2 = 91%

8 Clinical Case What are the therapeutic options?

9 A. Salt restriction B. IV Loop Diuretics C. Resume previous treatments D. Add new medications E. Consider other procedures

10 What do ESC guidelines say?

11 Symptomatic heart failure + reduced ejection fraction Detect major Co-morbidities and Precipitating Factors Non-cardiovascular Anemia Pulmonary disease Renal dysfunction Thyroid dysfunction Diabetes Cardiovascular Ischemia/CAD Hypertension Valvular dysfunction Diastolic dysfunction Atrial fibrillation Ventricular dysrhythmia Bradycardia Yes Diuretic + ACE inhibitor (or ARB) Titrate t to clinical i l stability Betablocker Persisting signs and symptoms? ADD aldosterone antagonist t OR ARB No Yes Persisting symptoms? No QRS duration > 120 msec? LV ejection fraction < 35%? Yes No Yes No Consider: CRT or CRT-D Consider: digoxin, hydralazine/nitrate LVAD, transplantation Consider ICD No further treatment

12 ESC guidelines 2008 Weight monitoring : In case of sudden unenexpectedweight gain > 2 kgs in 3 days, patients may adjust their diuretic dose and should alert the health care team. Class I Level of evidence C Sodium intake: Sodium restriction is recommended in symptomatic HF and excessive intake of Na + should be avoided Class IIa Level of evidence C

13 Diuretics: ESC Guidelines 2008 Are recommended in HF patients with signs or symptoms of congestion. Class I, Level B In general, loop diuretics are required in moderate to severe HF. If the effect is not achievable despite rapid uptitration, continuous furosemide infusion can be considered.

14 ESC Guidelines 2008 ACE Inhibitors: Unless contra indicated or not tolerated, ACE-I should be used in all patients with symptomatic HF and LVEF<40 %. Class I, Level A

15 ACE-inhibitor trials in heart failure / LV- dysfunction - mortality Randomized large (>1000 patients), long-term (1 year) trials ACE-inhibitor vs placebo patients in 4 trials SAVE, AIRE, TRACE SOLVD Total Better ACE-inhibitor Worse Flather et al Lancet 2000

16 Beta Blockers: ESC Guidelines 2008 Unless contra indicated or not tolerated, abb should be used in all patients with symptomatic HF and LVEF< 40 %. Class I Level A. Patients should be clinically stable. Cautious initiation is possible in a recently decompensated patient provided that patient has improved with other treatments, is not dependent on an IV inotrope and can be observed in hospital >24 hours after initiation.

20 ESC guidelines on CHF 2005 Aldosterone receptor antagonist: Is recommended in addition to ACE-inhibition and beta-blockade blockade in heart failure after myocardial infarction with left ventricular systolic dysfunction and signs of heart failure to reduce mortality and morbidity (level of evidence B, class I).
