Definition of HF A syndrome associated with inadequate

performance of the heart.

Leading to neurohormonal and circulatory abnormalities

Adam KF et al. HFSA 2006 comprehensive heart failure guideline J Card Fail 2006; 12: e1-e122

Epidemiology

Heart failure is a major and growing cause of cardiovascular morbidity and mortality throughout the world

Approximately 5 million patients in USA have HF, and over 550 000 patients are diagnosed with HF for the first time each year.

HF is the primary reason for 12 to 15 million office visits and 6.5 million hospital days each year.

ESC Guideline for Diagnosis and Treatment Acute and Chronic Heart Failure , 2008

Causes of HF

• CAD• Hypertension• Valve disease (RHD, endocarditis)• Arrhythmias• Cardiomyopathy• Congenital heart disease• Pericardial Effusion

Systolic vs. Diastolic HF

Heart failure is a major and growing cause of cardiovascular morbidity and mortality throughout the world

Previously, it had often been assumed that most heart failure patients have underlying systolic dysfunction, which is responsible for their clinical presentation

It has become increasingly apparent over the last decade that many heart failure patients have a normal or nearly normal ejection fraction described as heart failure with preserved systolic function or preserved ejection fraction

HF-PEF affects primarily older patients, especially women; hypertension is the primary underlying condition, with CAD and prior MI being relatively infrequent

Hogg K, Swedberg K, McMurray J. J Am Coll Cardiol 2004; 43:317-327.

Systolic vs. Diastolic HF

Heart failure 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

Systolic HF vs HF-PEF: Signs and Symptoms

Givertz MM et al. In: Braunwald E, Zipes DP, Libby P, eds. Heart Disease, A Textbook of Cardiovascular Medicine. 7th edition. Philadelphia, WB Saunders. 2001;534-561.

CHF vs. AHF

Current management of acute coronary syndrome has resulted in an improved survival after acute myocardial infarction.

This fact has created a rapid growth in the number of patients currently living with chronic heart failure.

Decompensation of preexisting chronic heart failure may cause acute heart failure (AHF).

Eur Heart J 2005;26:384-416

• AHF is defined as the rapid onset of symptoms and signs, secondary to abnormal cardiac function

• Cardiac dysfunction can be related to systolic or diastolic, to abnormalities in cardiac rhythm or to preload and afterload mismatch

• It is often life threatening and requires urgent treatment

Definition of Acute Heart Failure

ESC guideline for Acute Heart Failure, 2005

Cause of Acute Heart Failure

Acute coronary syndrome, hypertensive crisis and other cardiac or non cardiac also precipitate an AHF.

CAD contributes to 60-70 % in elderly Cardiomyopathy, CHD, arrhythmia, myocarditis and

valve diseases found in young

AHF therefore has significantly become the single most costly medical syndrome in emergency.

Early diagnosis and vascularization prevent HF

Delay and inadequate treatment iireversible cardiomyocyte loss

Myocardial infarction leads to heart failure

Obstruction of coronary arteries leads to myocardial infarction (heart attack) with the associated death of cardiomyocytes

Regenerative capacity ? Not adequately compensate

Overloads the surviving myocardium and eventually leads to heart failure

Segers VF, Lee RT. Nature 2008; 451: 937-942.

Terminal differentiation of cardiomyocytes

Cardiac myocytes rapidly proliferate during fetal life but exit the cell cycle soon after birth in mammals1

The vast majority of adult cardiac myocytes the predominant form of growth postnatally is an increase in cell size (hypertrophy)2

This limits the ability to restore function after any significant injury2

1. Ahuja P, et al. Physiol Rev 2007; 87: 521–544. 2. Segers VF, Lee RT. Nature 2008; 451: 937-942.

Problem with Infarcted Heart

Current medical therapies of heart failure only delay progression of the disease

The only standard therapy for cardiomyocyte loss is cardiac transplantation

New discoveries on the regenerative potential of stem cells have transformed experimental research and led to an explosion in clinical investigation
