insuficiencia cardiaca, lo nuevo

Definition
• HF is a complex clinical syndrome that results
from any structural or functional impairment
of ventricular filling or ejection of blood.

Epidemiology
• The lifetime risk of developing HF is 20% at 40 years of age.
• HF incidence: >650 000 new HF cases diagnosed annually
• HF incidence increases with age, rising from approximately 20
per 1000 individuals 65 to 69 years of age to >80 per 1000
individuals among those >85 years of age.
• Mortality rates for HF remain approximately 50% within 5
years of diagnosis

NUMBER of PATIENTS
21 MILLION adults worldwide are
living with heart failure
This number is expected to
rise.1,2
REHOSPITALISATION
Heart failure is the NUMBER 1
cause of hospitalisation for
patients aged >65 years.4
MORTALITY
50% of heart failure patients die
within 5 years from diagnosis.5
COMORBIDITIES: The vast
majority of HF patients has 3 or
more comorbidities 3
ECONOMIC BURDEN
In 2012, the overall worldwide
cost of heart failure was nearly
$108 BILLION.6

• Prevalence of HFpEF among patients with a discharge diagnosis of HF increased from
38% to 54% from 1987–20011
• Increasing prevalence of HFpEF may be a consequence of growing recognition,
population aging and increases in hypertension and obesity2

The diagnosis of HFrEF requires three conditions to be satisfied
1. Symptoms typical of HF
2. Signs typical of HF
3. Reduced LVEF
The diagnosis of HFpEF requires four conditions to be satisfied
1. Symptoms typical of HF
2. Signs typical of HF
3. Normal or only mildly reduced LVEF and LV not dilated
4. Relevant structural heart disease (LV hypertrophy/LA enlargement) and/or
diastolic dysfunction

The diagnosis of HFpEF is more difficult than the diagnosis of HFrEF
Diagnosing HF

There are many treatment objectives for chronic HF
• Dickstein et al. Eur Heart J 2008;29:2388–442
• McMurray et al. Eur Heart J 2012;33:1787–847
Objectives of treatment for chronic HF
1. Prognosis • reduce mortality
2. Morbidity • relieve symptoms and signs
• improve QoL
• eliminate edema and fluid retention
• increase exercise capacity
• reduce fatigue and breathlessness
• reduce the need for hospitalization
• provide end of life care
3. Prevention • occurrence of myocardial damage
• progression of myocardial damage
• remodelling of the myocardium
• reoccurrence of symptoms and fluid
accumulation
• hospitalization

disease-modifying agents
• Important implications for clinical practice and HF guidelines
• Efficacy in treatment of HFpEF remains to be established
SALIENT FEATURES OF SGLT2 INHIBITORS

Device Therapy for HF
• Implantable cardioverter-defibrillator
• Cardiac resynchronization therapy
• Mechanical Circulatory Support
• Cardiac Transplantation

Digoxin: recommendation
• Digoxin can be beneficial in patients with HFrEF,
to decrease hospitalizations for HF
• treatment with digoxin for 1 to 3 months can improve
symptoms, HRQOL (Health Related Quality of Life),
and exercise tolerance in patients with mild to
moderate HF
• treatment with digoxin for 2 to 5 years had no effect
on mortality but modestly reduced the combined
risk of death and hospitalization
• Digoxin can be used only in patients who remain
symptomatic despite therapy with the
neurohormonal antagonists or in patients with AF

BACKGROUND
1Abraham WT
, et al. Lancet 2011:377:658-666.
• The burden of HF hospitalization (HFH) remains high despite
increasingly effective medical therapy
• Most HFH occur because of ‘congestion’ or elevated cardiac filling
pressures
• Increases in pulmonary artery (PA) pressures occur weeks in
advance of the signs and symptoms that prompt HFH
• Therapy guided by PA pressures in the randomized CHAMPION
study1 resulted in a 37% reduction in HFH rates and all cause
hospitalization (ACH)

• In the commercial setting, PA pressure-guided therapy for HF:
• Decreased PA pressures
• Decreased HF Hospitalizations
• Across sex and race
• Across all EF ranges
• Amongst 1-year survivors
• Decreased All-Cause Hospitalization
• PA pressure-guided therapy was safe with few device/system related
complications and a low rate of pressure sensor failure
CONCLUSIONS OF CHAMPION TRIAL

An overview of the presented novel therapeutic methods with
respect to their mechanism of action and latest stage of
clinical development
Machaj et al,. New therapies for the treatment of heart failure: a summary of recent accomplishments. Therapeutics and

Summary & Conclusions
• Prevalence of HF is fast assuming epidemic proportions
as evident by growing number of hospitalizations,
increased mortality & spiraling costs associated with it.
• Prognosis remains dismal as mortality is higher than
many malignancies.
• Diagnosis of HF is clinical but classification requires
ECHO assessment
• HFpEF comprises 50% of total HF cases
• Treatment of HFrEF is well established with
ACEi/ARB/ARNI, MRA, Beta blockers providing
substantial mortality benefit.
•

Contd..
• Specific therapy for HFpEF is still a distant dream & treating
co-morbid conditions remains only option.
• Device therapy like ICD, CRT & IHM are beneficial come at
expense of prohibitive cost.
• Newer drugs continue to evolve to combat the deadly
disease. Omecamtiv mecarbil, Vericiguat, Rolophylline,
Istaroxime are few examples.
• SGLT2 inhibitor is the new hope to millions of HF patients with
DM.
• A time may come when SGLT2 inhibitors will be routinely
used in HF patients irrespective of diabetic status.
