Drugs for ccf

Drugs for CCF

  • Heart failure is the progressive inability of the heart to supply adequate blood flow to vital organs.

  • It is classically accompanied by significant fluid retention.

  • It is a leading cause of mortality and morbidity.


Drugs for ccf1

Drugs for CCF

  • The most common symptoms of CCF includes shortness of breath, edema and fatigue.

  • Causes of heart failure includes Coronary artery disease (CAD), Hypertension, Diabetes, Mitral valve disease and Chronic alcohol.


Drugs for ccf2

Drugs for CCF


Drugs for ccf3

Drugs for CCF

  • Vasodilators – ACE Inhibitors

  • Diuretics

  • Beta blockers

  • Digoxin

  • Other Cardiac Inotropes – Dobutamine, Milrinone


Drugs for ccf4

Drugs for CCF

Angiotensin Converting Enzyme (ACE) Inhibitors :

  • ACE inhibitors improve mortality, morbidity, exercise tolerance, left ventricular ejection fraction.

  • Captopril, Lisinopril, Enalapril, Ramipril, Quinapril.

ACE Inhibitors for CCF


Ace inhibitors for ccf1

ACE Inhibitors for CCF


Drugs for ccf5

Drugs for CCF

Angiotensin Converting Enzyme (ACE) Inhibitors :

  • Reduction in arterial resistance (afterload)

  • Reduction in venous tension (preload)

  • Reduction in aldosterone secretion

  • Inhibition of cardiac and vascular remodeling


Drugs for ccf6

Drugs for CCF

Angiotensin Converting Enzyme (ACE) Inhibitors :

Adverse effects :

  • Dry irritating persistent cough

  • Hyperkalemia

  • Angioedema

  • Fetal toxicity


Drugs for ccf7

Drugs for CCF

Angiotensin Receptor AT-1 blockers (ARB) :

Losartan, Irbesartan, Candesartan

  • Competitive antagonists of Angiotensin II (AT-1).

  • No inhibition of ACE or Cough.


Drugs for ccf8

Drugs for CCF

Vasodilators :

  • Isosorbidedinitrate and hydralazine also used specially in patients who cannot tolerate ACE inhibitors.

  • Amlodipine and prazosin are other vasodilators can be used in CCF.

Drugs for CCF

Diuretics :

These are useful in reducing the symptoms of volume overload by

  • decreasing the extra cellular volume

  • decreasing the venous return


Drugs for ccf10

Drugs for CCF

Diuretics :

  • Loop diuretics like furosemide and bumetanide are the most effective and commonly used.

  • Thiazides are effective in mild cases only.


Drugs for ccf11

Drugs for CCF

Diuretics :Adverse effects :

  • Loop diuretics and thiazides cause hypokalemia.

  • Potassium sparing diuretics help in reducing the hypokalemia due to these diuretics.


Drugs for ccf12

Drugs for CCF

Potassium Sparing Diuretics : Spironolactone :

  • Aldosterone inhibition minimize potassium loss, prevent sodium and water retention, endothelial dysfunction and myocardial fibrosis.


Drugs for ccf13

Drugs for CCF

Spironolactone : Aldosterone antagonist

  • Spironolactone can be added to loop diuretics to modestly enhance the diuresis; more importantly, improve survival.


Drugs for ccf14

Drugs for CCF

Beta blockers for congestive cardiac failure :

  • Acts primarily by inhibiting the sympathetic nervous system.

  • Increases beta receptor sensitivity (up regulation).

  • Anti-arrhythmic properties.

  • Anti-oxidant properties.


Beta blockers in ccf

Beta blockers in CCF


Drugs for ccf15

Drugs for CCF

Beta blockers for CCF :

  • Start at low dose and monitor for bradycardia

  • Carvedilol and Metoprolol are the most commonly used for CCF amongst beta blockers


Drugs for ccf16

Drugs for CCF

Cardiac glycosides : Digoxin :

  • Inhibition of Na/K ATPase pump increase intracellular sodium concentration – eventually increase cytosolic calcium.

  • It restores the vagal tone and abolishes the sympathetic over activity.


Digoxin in ccf

Digoxin in CCF


Drugs for ccf17

Drugs for CCF

Cardiac glycosides : Digoxin :

  • Increase the refractoriness of AV node thus decrease ventricular response to atrial rate.

  • Digoxin is used as a first-line drug in patients with congestive heart failure who are in atrial fibrillation.


Drugs for ccf18

Drugs for CCF

Digoxin : Adverse effects / Precautions :

  • Nausea, vomiting, gynecomastia, visual disturbances and psychosis.

  • Ventricular bigeminy, AV block and bradycardia.

  • Amiodarone and verapamil can increase the plasma concentration of digoxin by inhibiting its excretion.


Drugs for ccf19

Drugs for CCF

  • Digoxin toxicity treatment:

  • Toxicity can be treated with higher than normal doses of potassium.

  • Digoxin antibody (digibind) is used specifically to treat life-threatening digoxin overdose.


Drugs for ccf20

Drugs for CCF

Cardiac Inotropes :

  • Phosphodiesterase III Inhibitors Positive inotropic and vasodilator – INO-DILATOR ; Eg., Milrinone

  • Dobutamine is a beta-1 agonist which increase contractility and cardiac output.


Drugs for ccf21

Drugs for CCF

Conclusion :

  • ACE inhibitors are cornerstone in the treatment of CCF.

  • Beta blockers are used in selected patients (mild/moderate failure, low dose)

  • Diuretics and digoxin are other drugs useful in CCF in select patients.
