What is heart failure?• Chronic Heart Failure (CHF):

– Heart failure is a complex syndrome in which abnormal heart function results in, or increases the subsequent risk of, clinical symptoms and signs of low cardiac output and/or pulmonary or systemic congestion.

• Acute Heart Failure Syndrome (AHF):– “gradual or rapid change in heart failure

signs and symptoms resulting in the need for urgent therapy”

Heterogeneity of AHF(ESC classification)

high BP, +/- preserved LV systolic fxn; increased sympathetic tone with ↑HR, vasoconstriction; may be euvolaemic or 

only mildly hypervolemic, and frequently with signs of pulmonary or systemic 

congestion 

Severe respiratory distress, ↑RR, orthopnea, rales.  O2 sats <90% RA prior to O2

Clinical and lab evidence of an ACS; ~15% of patients with an ACS have signs and symptoms of HF. Episodes of AHF are frequently assoc w/ or precipitated by arrhythmia (bradycardia, AF, VT).

Usually sys BP <90 mmHg or drop in MAP >30 mmHg and absent/low urine output. Organ hypoperfusion and pulmonary congestion develop rapidly

low output in absence of pulmonary congestion with increased JVP, w/ or w/out HSM, and low LV filling pressures

usually a hx of prog. worsening of known chronic HF on Rx, and evidence of systemic/pulmonary congestion. 

ESC 2008 and 2012A « bouillabaisse » …

The picture of AHF has changed with time …

• Years ago– Younger population– Predominance of unrevascularised AMI– Or old valvular diseases

• Prevalence of LV systolic dysfunction in patients with AHF• Nowadays

– Mean age 80 y– Altered arterial stiffness– Aged heart with low diastolic and systolic reserve – AF– Diabetes rates increase– ..

Epidemiology

– Clinical trials provide a biased wiew of the real incidence of HFpEF in ADHF

• Most of them have excluded pts with pEF• Exclusion of patients with rapide AF, severe renal failure or hypertension, infection, COPD, dementia, ischemia

• Which are frequent in HFpEF

– Registries dealing with patients hospitalized with HF mix pts with AHF and CHF

Reduced LV compliance response & Excessive Arterial stiffening

Conclusion

• AHF is frequent and associated with poor outcome

• Epidemiology has changed with time• HFpEF becomes the main cause of AHF hospitalizations

• Phenotype is different : age, BP, comorbities• Less difficult to treat ?• From a « marketing » viewpoint, this population should be the one to target …
