Definition:

Heart failure (functional impairment of ventricular filling and/or ejection of blood).

Congestive heart failure (clinal syndrome in which the heart is unable to pump enough blood to body). BP = CO x TPR

CO = HR x SV

SV depends on (preload, afterload, contractility). https://t.co/3KXCIgTu3U

Types of HF:

1-systolic heart failure

contractility decreased

⁃MI (anterior/ lateral)

⁃Dilated cardiomyopathy (floppy heart)

Preload increased with contractility decreased

⁃mitral regurgitation

⁃Aortic regurgitation

⁃Tachy / brady arrhythmia https://t.co/Tvh883rn7k

2-diastolic heart failure

Preload decreased

⁃MI

⁃Restrictive cardiomyopathy

⁃Constrictive pericarditis

⁃Cardiac tamponade

Afterload increase

⁃HTN

⁃Aortic stenosis

⁃Coarctation of aorta

⁃Hypertrophic obstructive cardiomyopathy https://t.co/JpSSurJrcy

3-Right side HF

Afterload increase

⁃pulmonary stenosis

⁃Pulmonary HTN

⁃Pulmonary Embolism

⁃Cor pulmonale

Preload increase

⁃tricuspid regurgitation

⁃Pulmonary regurgitation

Contractility decrease

⁃MI (inferior)

⁃Myocarditis https://t.co/bEYCGf1VIb
