This document provides an overview of heart failure management. It defines heart failure and describes its types and classifications. Symptoms include dyspnea and fatigue while signs include circulatory congestion or hypoperfusion. Treatment involves establishing a diagnosis, determining risk factors and severity, and taking a multidisciplinary approach. The main treatment goals are reducing mortality and morbidity by modifying risks, preventing disease progression, and improving quality of life. Guideline directed medical therapy includes diuretics, ACE inhibitors, beta blockers, MRAs, ARNIs, and SGLT2 inhibitors. Device therapies like ICDs and CRT can be used, and management depends on the ACC/AHA stages of heart failure.
Heart Failure with Preserved Ejection Fraction(HFpEF).ptxSarfraz Saleemi
Heart failure with preserved ejection fraction (HFpEF) is not one disease but a clinical syndrome presenting with symptoms of Heart Failure with a left ventricular ejection fraction (LVEF) ≥50 percent and evidence of cardiac diastolic dysfunction. (abnormal LV filling pattern and elevated filling pressures)
It is more common among older patients and women, and results from abnormalities of active ventricular relaxation and passive ventricular compliance. HFpEF should be part of differential diagnosis in patients with typical symptoms such as fatigue, weakness, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, edema and clinical signs of chronic heart failure. Echocardiography features of normal ejection fraction with impaired diastolic function confirm the diagnosis.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
3. Definition & Types of HF
Heart failure is a complex pathophysiological state. Failure of the heart to
pump sufficient amount of blood to fulfill the body demand or can do so at
the cost of raised filling pressure-LVEDP ( compensated HF).
When heart fails to maintain adequate cardiac output.
Symptoms-dyspnea and fatigue
Signs of circulatory congestion or hypoperfusion.
Classification:
Acute or Chronic Heart Failure
Left or Right Heart failure,
High output or Low output Failure,
Systolic & Diastolic Failure,
HFrEF & HFpEF.
4. Heart Failure Nomenclature
depending on Echo, RNVG, CMR.
There is up to 10% inter/intra-observer variability of EF.
EF in between 40-49% is Gray Zone.
5. HF Classification
ACC/AHA Stages of Heart Failure (HF) Compared to NYHA Functional Classification
HF Classification: Stages A-D
Disease Evolution & Progression
NYHA- Functional Classification
Class I-IV
Stage A: Patient at high risk for developing HF with
no structural disorder of the heart.
None
Stage B: Patient with structural disorder without
symptoms of HF
Class I: No symptoms with ordinary activity
Stage C: Patient with past or current symptoms of
HF associated with underlying structural heart
disease
Class II: Slight limitation of physical activity. Comfortable at rest, but
ordinary physical activity results in fatigue, palpitation, dyspnea, or
angina.
Class III: Marked limitation of physical activity. Comfortable at
rest, but less than ordinary physical activity results in
fatigue, palpitation, dyspnea, or angina.
Stage D: Patient with end-stage disease who
requires specialized treatment strategies
Class IV : Unable to carry out any physical activity without
discomfort. Symptoms of cardiac insufficiency may be
present even at rest
6. Management outline of HF r EF
• Establish a firm Diagnosis of HF, exclude the HF mimicking conditions(obesity,
Lung disease, CKD, CLD, anemia, drugs).
• Determine the risk factors/etiology, ppt factors, comorbidities and severity of HF.
• Precipitating factors- poor compliance to Rx, drugs-NSAIDs/steroid, anemia,
obesity, arrhythmias (AF), CAD, progression of pathology.
• Multidisciplinary approach( for Comorbidities)- Gen. practitioner
(GP),Internist, dietician, Diabetologist, pulmonologist, nephrologist, cardiac
rehabilitation, EPS.
• Objectives:
• Reduce Mortality (death), prolong life expectancy.
• Morbidity- symptoms, quality of life, exercise capacity, reduce HF hospitalization.
• Modification of risk factors/etiology and prevention of disease progression.

9.
10. Diuretics and MRA.
(Furosemide,Bumetanide,Torasemide, HTZ, Spironolactone, Eplerenone)
• Loop diuretics choice of drug for all HFrEF and congestion, should be
started first . S/E- E.I.
• ACE-I reduces the aldosterone secretion but it’s transient and with chronic
therapy with ACE-I, aldosterone level rapidly return to normal.
• MRA is indicated in HFrEF < 35%, NYHA- II-IV and patient is on other
standard Rx ( Diuretic, ACE-I & BB).
• MRA is C/I in CKD with S. Creatinine >2.5 mg/dl, CCR < 30 ml/mint.
• Check S. K+ after 3 days.
• Painful gynecomastia- 10-15%, Eplerenone is an option.
• MRA- diuretic , K sparer, ↓myocardial fibrosis.
11. ACE-I & ARB
• Overwhelming evidences of benefits of ACE-I in reducing mortality ,
increase the longevity, improve symptoms, HF hospitalization.
• Indicated in all patients with symptoms and asymptomatic patients with LVEF <40%.
• ACE-I inhibits Kininase , thereby reduce breakdown of bradykinin, that has
addition benefits in vasodilatation, over ARB.
• Should be started with low dose, preferable after with diuretics because if
diuretics are not used, fluid retentions from kidneys will attenuates the
effects of ACE-I and ARB.
• Dose should be increased gradually every 24-48 hrly ( c.f. to BB- 5-7 days
interval) till higher/recommended dose is not achieved.
• However before giving the highest dose of ACE-I, better to start BB, so that
BB can be used in adequate dose to reduce the HR without producing
hypotension.
• Higher the dose of ACE-I (BB), better the benefit. But it’s better to treat
with low/modest dose of both ACE-I & BB, than highest dose of any one of
these.
12. ACE-I and ARB.
• Abrupt withdrawal may deteriorate the symptoms, so should be avoided
except in life-threatening condition e.g. angioedema and hyperkaelemia.
• Blood pressure, renal function and S. K+ -monitoring after 1-2 wks.
specially if there in preexisting CKD.
• ARB are indicated only when ACE-I are not tolerated due to cough,
angioedema, skin rash.
• Losartan, valsartan(widely studied) and candesartan.
• Aliskiren-direct renin inhibitor- major trials fails to prove it’s benefit and
there not recommended as an alternative to ACE-I or ARB.
• Hydralazine and NO3- alternative if ACE-I & ARB both are not tolerated,
specially in African American black people.
13.
14. ARNI( ARB+ Neprilysin inhibitors)
Valsartan & Sacubitril.
Neurohumoral system modulation.
• RAAS inhibitors- so reduce vasoconstriction, H2O retention,
myocardial hypertrophy, fibrosis.
• Neprilysin Inhibitors- Slows degradation of natriuretic peptides,
bradykinin& adrenomedulin- thereby enhance diuresis, natriuresis, &
myocardial relaxation.
• Reverse ventricular remodeling (recovery/normalization or remission).
• ARNI- is included in GDMT.
• It should not be started within 36 hrs. of stopping ACE-I because of
angioedema.
15. Beta Blocker
• HF activation of autonomic nervous system, adrenergic activities (alfa ἀ
1, ß 1 & ß 2)
• ß ßlockers - Metoprolol>>antiarrhythmia,Carvidilol ( alfa : Beta blocking=
1:2)>>Antifailure, bisoprolol B1>B2=100,>>BA,COAD.
• Should be started at low dose and titrated very slowly 1-2 weekly, because
initiation and increase in dosing may produce fluid retention due to abrupt
withdrawal of adrenergic support from heart and circulation. So better to
start and optimize the diuretic before starting BB and ACE-I.
• Combination of BB and ACE-I at lower tolerated dose is better than
individual drug at higher dose.
• Even after BB if HR remain >70 bpm or if BB is contraindicated, Ivabradin is
indicated. >>low BP, BA.
16. SGLT 2 Inhibitors
Cana-, Dapa-, Empagliflozin, ertugliflozin
• Diabetic patients are at higher risk of HF compared with healthy persons.
• Sodium Glucose Co-transportert 2 (SGLT2)- is not included in GDMT. It’s an
beneficial adjunctive to GDMT in HFrEF.
• Anti-diabetic effect, Cardio protection, anti-failure, reno-protection.
• Reduce HbA1C, Diuresis, weight reduction.
• It promotes hepatic ketones synthesis ( Beta OH buterate), that is utilized
by myocardium and kidney and preferentially Oxidized with more energy
production by less O2 consumption ( FFA oxidation needs more O2
utilization).
• Na+/H exchanger 1 (NHE-1) produce cardiomyocyte injury and decreases
mitrochondrial Ca+decrease ATP production. DM and HF patients have
higher NHE-1 level. SGLT2 inhibitor inhibits the NHE-1 .
17.
18. Na/H+ Exchanger in myocyte
(HF & DM-express this system)-
myocyte injury, decrease mitochondrial ca+less ATP/energy.
19. Device therapy for CHF
• ICD- to prevent SCD.
• CRT-D/P.
• His bundle pacing & LB Pacing .
• Make QRS narrow and synchronize ventricular contraction.
• Slime- great looking. Wide QRS- worse prognosis-all cases.

Mode of Death of Heart Failure patients.
21. Wide QRS Duration (LBBB/IVCD)
• Approximately 30-50% of patients
with HF have abnormal ventricular
contraction and mechanical
dyssynchrony. Many of them are
LBBB.
• VEST Study reported QRS duration is
an independent predictor of
mortality in patients with Class II-IV
HF
• Relative risk associated with the
widest QRS (>220ms) was 5
times greater than narrowest
(<90ms)
22. Effect of Ventricular Dyssynchrony
• Dyssynchrony produces:
Ineffective ventricular Systole and reduced SVO => CO.
Impaired diastolic Filling/Diastolic dysfunction.
MR and TR.
In case of LBBB last segment of LV that is depolarized and contract is Lateral wall of LV
and anterolateral papillary muscle. So not only the synchronized contraction is lost but
also due to papillary muscle dysfunction variable degree of MR occurs , that further
decrease the effective SVO/CO.
Significant systolic improvement may be achieved by electrically stimulating the site of
late activation and improving the ventricular activation sequence.
Increase in LVEF from 25% to 30%, apparently seems to be 5%. But actually/absolutely it
is 20% improvement of cardiac contraction/SVO. Moreover with early lateral wall &
lateral papillary muscle contraction and LV synchronization MR also reduced , thereby
forward output increases.
