Heart Failure
• Heart Failure is a silently progressive condition
• Heart Failure (as is fever) is not a disease, it is a manifestation of distinct cardiovascular disorders
• We begin to look at the disorder at the end of ist naturalhistory – this is too late.
• Many patients at earlier/less severe stages fly „underthe radar“
• Different clinical projectories: Same EF, different speedsof progression – role of metabolomics, genomics etc.?

Refractory end-stage HF(200.000)
D
• Known structural heart disease• Shortness of breath and fatigue• Reduced exercise tolerance

C
• Previous MI• LV systolic dysfunction• Asymptomatic valvular disease
Asymptomatic HF(10 mil.)

Braunwald definition
A clinical syndrome caused by the inability of the heart to supply blood to the tissues commensurate to the metabolic needs
of that tissue, or is achieved so only at the expense of elevated filling pressures.

Principles of Diagnosis
1. Consider ! (Medical history, signs, symptoms)
1. Confirm (e.g., Natriuretic peptides, Echocardiography)
1. Assess clinical phenotype (e.g., HFrEF vs. HFpEF)
1. Assess etiology (Angiography, cMRI, Biopsy)
1. Risk stratification
1. Workup for targeted therapies

Definitions of HF
• HFrEF (reduced EF) EF <40%
• HFmEF (mildly impaired EF) EF 40-49%
• HFpEF (preserved EF) EF ≥50%
• New onset, transient, chronic
• Acute, worsening
• Left heart, right heart, combined

Assessment of cardiac remodeling:Targets for Therapy
1. Structural remodeling
- Left ventricular hypertrophy, left atrial volume (HFpEF)
- Left ventricular end-diastolic volume; end-systolic volume
- Regional wall motion abnormalities
- Fibrosis (late enhancement, T1 mapping)
- Vascular remodeling (CAD)
2. Functional remodeling
Diastolic function (E´, E/E´, LVEDP)
Systolic function (e.g. ejection fraction, strain)
3. Electrical remodeling
LBBB
Atrial fibrillation
Ventricular arrhythmia
4. Metabolic remodeling/ energetic function
- Mitochondrial dysfunction
- Myocardial substrate uilization

After completing acquisition of images (~3 minutes), resume ramped protocol
Ramp + 5 W m-1

Diagnosis of Heart Failure – A staged process
Risk assessment at
preclinical stage
Initial diagnostic workup
in symptomatic patients
• Clinical
assessment/Comorbidities
• Biomarkers (Cardiac +EOD)
• Echocardiography
• Stress test
Detailed workup in case of
uncertainity
• Stress echocardiography
• Invasive tests & hemodynamics
• Cardiac MRI
• Comorbidities
Underlying
pathophysiology & etiology
• Cardiac MRI +++
• Biopsy
• Scintigraphy
• SPECT, Molecular imaging (?)

Summary
• Heart failure is a syndromal disorder with multiple phenotypic expressions
• HF Diagnosis should be considered at all levels of care: Lay education, Nurse, GP, Internist, Cardiologists
• Screening for cardiac dysfunction in patients at risk
• Confirmation of HF diagnosis by objective diagnosticmeasures essential (ECG, echo, BNP)
• Minute further workup for the underlying phenotype(HFrEF vs HFpEF!) and etiology is crucial
• New diagnostic technologies allow better and targetedtherapies
