Controversies in heart failure diagnosis
Dr. Frans Rutten, Utrecht, The Netherlands
Background
•
•
•
•
Disease of the elderly (1% of HF aged <65 years)
(Early) diagnosis of slow onset HF is in primary care
‘always’ left sided; only <1% cor pulmonale
Prevalence 1-1.5% (20-30 patients per practice)
• 30% with a GP’s HF label: No HF
• 30% of HF patients unknown
* never detected
* detected (much) later
in time course
ESC 2008 definition of heart failure
I. Symptoms typical of heart failure
and (not always!)
II. Signs typical of heart failure
and
III. Objective evidence of a structural
or functional abnormality of
the heart at rest
2005:
Only symptoms obligatory
Objective evidence of (left) ventricular dysfunction
- decreased LVEF (LVEF <45%)
: HFREF
- LV filling and relaxation abnormalities, ‘normal’ LVEF : HFPEF
When should we think of HF?
• Any patient with * shortness of breath
* exercise intolerance/fatigue
* peripheral oedema
Especially in:
• Elderly (oldest old, multimorbidity, ‘fragile’)
• Prior myocardial infarction, other CHD (HFREF)
• Diabetes type II
(HFPEF)
• Longstanding hypertension
(HFPEF)
• Atrial fibrillation, (suspected) valvular disease
• COPD (labeled as COPD and ‘really’ COPD). Every year!
• Renal dysfunction (eGFR<30-45 ml/min/1.73m²)
Diagnosing heart failure is not easy!

 65 years: multimorbidity
What is heart failure ?
a complex clinical syndrome
• (left) ventricular dysfunction with origin in heart :
HFREF
• (left) ventricular dysfunction in response to endothelial
dysfunction (DM, etc) and pressure overload (HT):
HFPEF
reduced ability of the ventricle(s) to fill with or eject blood
The heart is unable to provide sufficient cardiac output to satisfy
the metabolic needs of the body.

slowly increase in dyspnoea, fatigue
166/92, 92 bpm
acute dyspnoea, orthopnoea,
166/92, 92 bpm
Displaced apex, no fluid overload
raised JVP, crepitations,oedema
Symptoms
• breathlessness (with exercise)
• exercise intolerance
always
• Fatigue
• ankle oedema (chronic venous insufficiency)
not always!
• orthopnoea/paroxysmal nocturnal dyspnoea
- early phase
• Increased urinating at night (>2x)
- diuretic use
• weight gain (>2 kg/wk)
Signs
• crepitations
• raised JVP
fluid overload
• oedema
• apical impulse displaced or sustained
• S3 gallop
very rare
• heart murmur
not very typical
• tachycardia, irregular pulse

Essentials of clinical diagnostic models
• Signs or symptoms of fluid overload (diuretics, early phase)
• Displaced/broadened apical impulse
• murmur
in elderly persons, male sex, prior CAD, diabetes
Screening COPD:
• HR >90 bpm
• BMI >30 kg/m²
Additional tests
slow onset
acute onset
• test treatment with diuretics : NO
test treatment with diuretics ?
• ECG: when normal HF <10%
ECG: when normal HF <2%
• Chest X-ray ?
Chest X-ray ?
• NTproBNP: when normal HF <10%
NTproBNP: when normal HF <2%
Echocardiogram
valvular disease
LVH, CMP
wall motion abnormalities
other cardiac abnormalities
causes of HF

Hartfalen richtlijn. Hoes et al. 2010
Causes for elevated ntproBNP levels
acute dyspnoea
slow onset dyspnoea
• ACS
age >75 years
• pulmonary embolism
atrial fibrillation
• acute renal failure
renal dysfunction
• pulmonary artery hypertension
LVH
• sepsis
severe COPD
Conclusions
• Dyspnoea, exercise intolerance/ fatigue, ankle oedema: Always think of HF
• Signs or symptoms of fluid overload (diuretics, early phase)
• Displaces/broadened apical impulse, murmur
in elderly persons, male sex, prior CAD, diabetes

essentials
Additional tests: ntproBNP most valuable
Lower exclusionary cut-points ntproBNP for slow onset than acute onset HF
Echocardiogram for diagnosis AND cause(s) AND whether HFPEF/HFREF
Always consider cause of HF, especially treatable ones (valves)!!
