WHAT IS HEART FAILURE? • “HF is a complex clinical syndrome that can result from any structural or functional cardiac disorder that impairs the ability of the ventricle to fill with or eject blood. The cardinal manifestations of HF are dyspnea and fatigue, which may limit exercise tolerance, and fluid retention, which may lead to pulmonary and peripheral edema. Both abnormalities can impair the functional capacity and quality of life of affected individuals, but they may not necessarily dominate the clinical picture at the same time.” Evaluation and Management of Chronic Heart Failure in the Adult A Report of the ACC/AHA Task Force on Practice Guidelines February 2002 • Supply is less then demand • Failure of the heart as a pump
Systolic/Diastolic – does it matter? Systolic: • heart cannot contract normally and cannot pump enough blood into the arteries (EF<40%) Diastolic: • heart cannot relaxand fill normally and cannot pump enough blood into the arteries (EF>40%)
Left, right, or both? Right Heart Failure • Results in increased, systemic venous congestion and peripheral oedema Left Heart Failure • Results in pulmonary congestion
Different etiology – so what? • Many causes but clinical manifestations similar • Coronary artery disease is the underlying cause of HF in approximately two thirds of patients with ischemic left ventricular systolic dysfunction. • The remainder have nonischemic causes, e.g. hypertension, valvular disease, myocardial toxins, or myocarditis • or may have no discernible cause (e.g., idiopathicdilatedcardiomyopathy).
PHASE • Compensated phase • Supply temporarily meets the altered demand, no or very mild symtoms and signs • Decompensated heart failure: • new or worsening symptoms/signs of dyspnoea, fatigue or oedema leading to hospitalisation or unscheduled medical care
Terminology or just semantics? Congestive Heart Failure (CHF) • Heart failure withextra fluid in vessels and tissues Acute heart failure (AHF) • sudden initial episode of HF, severe symptoms; frequent pulmonary edema Chronic heart failure (CHF) – (chronic HF) • Slow process of myocardium destruction, often unnoticed, mild to moderate symptoms; frequent peripheral edema, may follow acute insult Acute exacerbation of chronic heart failure • Immediate and massive decompensation of the previously existing chronic heart
Current indication Acutely Decompensated Severe Low-output Chronic Pre-existing Symptomatic -24 hours? -Abruptly -Suddenly NYHA III-IV Cardiac – -EF<40% -CI<2.0 l/min/m2 -Cold Congestive Heart Failure (CHF)
ONSET Acute heart failure: • sudden onset of symptoms or signs of heart failure in a patient with no history of heart failure and previously normal cardiac function
ONSET Exacerbation of chronic heart failure: • patient with established diagnosis of heart failure who develops increasing signs or symptoms of the disease after a period of relative stability
Conceptual differences between acute and chronic heart failure • Chronic heart failure: • neurohumoral disease that responds to neurohumoral intervention • Remodeling, RAAS, cateholamines, PDE • Acute heart failure: • haemodynamic disease that responds to haemodynamic interventions
Acute de novo heart failure Myocardial infarction Arrhythmias Valve destruction Myocarditis Hypertensive crisis Cardiac surgery Decompensated chronic heart failure Myocardial ischaemia Arrhythmias Malcompliance Infections Salt overload Hypertension Classification and causes of heart failure Pulmonary oedema Low output heart failure (congestion) Cardiogenic shock
Differences between acute heart failure and decompensated Chronic HF Haemodynamics: AHF: RV +/- LV, normovolaemic Decompensation of Chronic HF: both RV and LV, increased EDV, hypervolaemic Prognosis: AHF: potentially reversible, stunning, sepsis Decompensation of Chronic HF: chronic disease

Levosimendan • Calcium sensitisation through bindingto troponin C • increases cardiac contractility and efficiency • Opening of ATP-sensitive potassium channels in vascular smooth muscles • pulmonary, coronary, systemic vasodilation
Calcium Sensitization by Levosimendan • No increase in cAMP • No increase in i/c calcium • No increase in energy consumption • No arrhythmogenicity • No impairment in relaxation • Anti-stunning effect • No antagonism by -blockers
Heart Failure LIDO study • 203 patients with severe HF, levo vs. dobut CASINO study • 299 patients low-output HF, levo vs. dobut vs. placebo. REVIVE-2 study • 600 patients. Levo vs placebo. Higher early mortality, but no difference at 90 days. SURVIVE trial 1327 patients, levo vs. dobutamine: No mortality difference at 180 days.
IHD and Cardiac surgery • RUSSLAN study • 504 patients with recent MI, levo vs. placebo. Trend to lower mortality at 180 days. • Small studies in cardiac surgery show levosimendan increases cardiac output and lowers SVR
Mostar study in 20 patients NYHA III-IV • aged 43-84, average 69 • All patients treated with ACE inhibitors, diuretic, beta blockers, aldosterone blockers, statins, and cardiotonics (digoxin chronically and dobutamin, dopamine in the shortly crisis period). • on follow-up1-3 day after infusion and 3 and 6 month, and 1-2-3 year after.
Levosimendan and NYHA Mean=-1.0000Std Dev=0.6124 P< 0.0001
Levosimendan and EFLV Mean=15.7059Std Dev=14.3952 P= 0.0004
Distrubtion of FS with levosimendan Med=0.0818 SD=0.0915 P= 0.002
Conclusion 1 • Experience from our practice shows that single dose of Levosimendan in patients with decompensated advanced heart failure produces significant improvement, which reflects in extension of life.
Conclusion 2 • Use of Levosimendan seams to be beneficial demonstrated by great benefit in the quality of life with better systolic function without any arrythmogenic effect.
Conclusion 3 • There are probably other benefits masked by uknown lusitropic and pleotropic influences of Levosimendan in the physiology and pathophysiology of heart and others systems of body.
Conclusion 4 • Almost all cases of death are results of co-morbidity disease, and are not related to levosimendan effect In the future • ICD device • Cardiac surgery • Transplantation
