3 Heart Failure in the US Heart Failure Patients in US (Millions) ~ 6 million symptomatic patients, estimated 10 million in 2037 Incidence: About 550,000 new cases/year More deaths from heart failure than from all forms of cancer combined Prevalence is 1% between the ages of 50 and 59, progressively increasing to >10% over age 80 Over $35 billion/year (5% to 7% of total health care cost) American Heart Association Heart Disease and Stroke Statistical Update.

4 Classification I. Heart Failure with Reduced Ejection Fraction (HFrEF) II. Heart Failure with Preserved Ejection Fraction (HFpEF) a. HFpEF, Borderline Definition of Heart Failure Ejection Fraction 40% 50% 41% to 49% Description Also referred to as systolic HF. Randomized clinical trials have mainly enrolled patients with HFrEF and it is only in these patients that efficacious therapies have been demonstrated to date. Also referred to as diastolic HF. Several different criteria have been used to further define HFpEF. The diagnosis of HFpEF is challenging because it is largely one of excluding other potential noncardiac causes of symptoms suggestive of HF. To date, efficacious therapies have not been identified. These patients fall into a borderline or intermediate group. Their characteristics, treatment patterns, and outcomes appear similar to those of patient with HFpEF. b. HFpEF, Improved > 40% It has been recognized that a subset of patients with HFpEF previously had HFrEF. These patients with improvement or recovery in EF may be clinically distinct from those with persistently preserved or reduced EF. Further research is needed to better characterize these patients.

12 Practical System Recommendations COR LOE ICD therapy is recommended for primary prevention of SCD in selected patients with HFrEF at least 40 days post-mi with LVEF 35%, and NYHA class II or III symptoms on chronic GDMT, who are expected to live 1 year* I A CRT is indicated for patients who have LVEF 35%, sinus rhythm, LBBB with a QRS 150 ms ICD therapy is recommended for primary prevention of SCD in selected patients with HFrEF at least 40 days post-mi with LVEF 30%, and NYHA class I symptoms while receiving GDMT, who are expected to live 1 year* CRT can be useful for patients who have LVEF 35%, sinus rhythm, a non-lbbb pattern with a QRS 150 ms, and NYHA class III/ambulatory class IV symptoms on GDMT. CRT can be useful for patients who have LVEF 35%, sinus rhythm, LBBB with a QRS 120 to 149 ms, and NYHA class II, III or ambulatory IV symptoms on GDMT CRT can be useful in patients with AF and LVEF 35% on GDMT if a) the patient requires ventricular pacing or otherwise meets CRT criteria and b) AV nodal ablation or rate control allows near 100% ventricular pacing with CRT I I IIa IIa IIa A (NYHA class III/IV) B (NYHA class II) B A B B

13 Practical System Patient with cardiomyopathy on GDMT for >3 mo or on GDMT and >40 d after MI, or with implantation of pacing or defibrillation device for special indications LVEF <35% Evaluate general health status Acceptable noncardiac health Comorbidities and/or frailty limit survival with good functional capacity to <1 y Continue GDMT without implanted device Evaluate NYHA clinical status NYHA class I LVEF 30% QRS 150 ms LBBB pattern Ischemic cardiomyopathy QRS 150 ms Non-LBBB pattern NYHA class II LVEF 35% QRS 150 ms LBBB pattern Sinus rhythm LVEF 35% QRS ms LBBB pattern Sinus rhythm LVEF 35% QRS 150 ms Non-LBBB pattern Sinus rhythm QRS 150 ms Non-LBBB pattern NYHA class III & Ambulatory class IV LVEF 35% QRS 150 ms LBBB pattern Sinus rhythm LVEF 35% QRS ms LBBB pattern Sinus rhythm LVEF 35% QRS 150 ms Non-LBBB pattern Sinus rhythm LVEF 35% QRS ms Non-LBBB pattern Sinus rhythm Special CRT Indications Anticipated to require frequent ventricular pacing (>40%) Atrial fibrillation, if ventricular pacing is required and rate control will result in near 100% ventricular pacing with CRT Colors correspond to the class of recommendations in the ACCF/AHA Table 1. Benefit for NYHA class I and II patients has only been shown in CRT-D trials, and while patients may not experience immediate symptomatic benefit, late remodeling may be avoided along with long-term HF consequences. There are no trials that support CRT-pacing (without ICD) in NYHA class I and II patients. Thus, it is anticipated these patients would receive CRT-D unless clinical reasons or personal wishes make CRT-pacing more appropriate. In patients who are NYHA class III and ambulatory class IV, CRT-D may be chosen but clinical reasons and personal wishes may make CRT-pacing appropriate to improve symptoms and quality of life when an ICD is not expected to produce meaningful benefit in survival.

42 Aldosterone Antagonists I IIa IIb III Aldosterone receptor antagonists are recommended in patients with NYHA class II-IV and who have LVEF of 35% or less, unless contraindicated, to reduce morbidity and mortality. Patients with NYHA class II should have a history of prior cardiovascular hospitalization or elevated plasma natriuretic peptide levels to be considered for aldosterone receptor antagonists. I IIa IIb III Aldosterone receptor antagonists are recommended to reduce morbidity and mortality following an acute MI in patients who have LVEF of 40% or less who develop symptoms of HF or who have a history of diabetes mellitus, unless contraindicated.

43 Aldosterone Antagonists I IIa IIb III Creatinine should be 2.5 mg/dl or less in men or 2.0 mg/dl or less in women (or estimated glomerular filtration rate >30 ml/min/1.73m2) and potassium should be less than 5.0 meq/l. Careful monitoring of potassium, renal function, and diuretic dosing should be performed at initiation and closely followed thereafter to minimize risk of hyperkalemia and renal insufficiency. Check potassium and renal function: - 2 to 3 days after starting therapy - 1 week after starting therapy, AND - At least monthly for the first 3 months

51 Need for Improved Care Coordination #1 reason for hospitalization for people >65 years of age National 30 day readmission rate 25% Mortality 50% at 5 years, 34% at 1 year following a hospitalization Many HF hospitalizations are driven by gaps in the process of care rather than worsening pathophysiology Collins SP, et al. J Am Coll Cardiol 2013;61:121-6.

52 Transitions of Care I IIa IIb III Throughout the hospitalization as appropriate, before hospital discharge, at the first postdischarge visit, and in subsequent follow-up visits, the following should be addressed: a. initiation of GDMT if not previously established and not contraindicated; b. precipitant causes of HF, barriers to optimal care transitions, and limitations in postdischarge support; Of the patients in Utah with HF, 87% c. assessment of volume status and supine/upright hypotension with have adjustment 3 or more of HF chronic therapy, conditions, as appropriate; and d. titration and optimization 54% of have chronic 5 or oral more HF therapy; chronic conditions. e. assessment of renal function and electrolytes, where appropriate; f. assessment and management of comorbid conditions; g. reinforcement of HF education, self-care, emergency plans, and need for adherence; and h. consideration for palliative care or hospice care in selected patients.

53 Transitions of Care I IIa IIb III I IIa IIb III I IIa IIb III Multidisciplinary HF disease-management programs are recommended for patients at high risk for hospital readmission, to facilitate the implementation of GDMT, to address different barriers to behavioral change, and to reduce the risk of subsequent rehospitalization for HF. Scheduling an early follow-up visit (within 7 to 14 days) and early telephone follow-up (within 3 days) of hospital discharge is reasonable. Use of clinical risk prediction tools and/or biomarkers to identify patients at higher risk for postdischarge clinical events is reasonable.

54 Sodium Restriction Mixed data evaluating sodium restriction in HF Observational data = association between sodium intake and risk for hospitalization RCTs = lower sodium intake is associated with worse outcomes in HFrEF No study has been done in optimally treated patients I IIa IIb III Sodium restriction is reasonable for patients with symptomatic HF to reduce congestive symptoms.

59 Clinical Events and Findings Useful for Identifying Patients With Advanced HF Repeated ( 2) hospitalizations or ED visits for HF in the past year Progressive deterioration in renal function (e.g., rise in BUN and creatinine) Weight loss without other cause (e.g., cardiac cachexia) Intolerance to ACE inhibitors due to hypotension and/or worsening renal function Intolerance to beta blockers due to worsening HF or hypotension Frequent systolic blood pressure <90 mm Hg Persistent dyspnea with dressing or bathing requiring rest Inability to walk 1 block on the level ground due to dyspnea or fatigue Recent need to escalate diuretics to maintain volume status, often reaching daily furosemide equivalent dose >160 mg/d and/or use of supplemental metolazone therapy Progressive decline in serum sodium, usually to <133 meq/l Frequent ICD shocks

60 Mechanical Circulatory Support Patient selection and Evaluation 1. Does the patient have a reversible cause of heart failure? 2. Is the patient on the maximum/tolerated standard medical HF therapy? 3. Is the patient candidate for CRT-D? If yes, will it make a difference? 4. What is the patient s prognosis in the next year without MCS?(High risk for mortality 50%). 5. Does the patient have any irreversible co-morbidities that will affect quality of life and survival after MCS implantation? 6. Does the patient have adequate financial and psychosocial support, and safe living environment? 7. Does the patient have high risk behavior?
