Heart Failure • Heart Failure _Mechanisms Heart Failure • CV Diseases-Review • Management of Heart failure Medical Surgical • Other Systems
C.H.F - Mechanisms • Connective Tissue Increased • Result: “Interstitial Heart Disease” • Altered: Systolic and diastolic function
CHF • Myocardial diseases • Coronary Artery Disease • Valvular disease • Interstitial Diseases
Lungs in C.H.F. (2) • Pulmonary lymphatics drain into Systemic veins. Elevated systemic venous pressure (in C.H.F.). Decreased lymphatic flow. Worsen pulmonary edema.
Mortality in C.H.F. • Prognosis: Poor • Severe Symptoms: 50% 1 year • Less Severe: 50% in 3-4 years
Complications of M .I. • Sudden Death -Arrhythmias • Acute Heart Failure • (Transmural Infarction) • (Subendocardial Infarction) • Mural Thrombosis • Myocardial Rupture : Free wall • I V Septum • Papillary Muscle • Left ventricular Aneurysm /Mural Thrombus • Chronic Congestive Heart Failure • Pericarditis

C.H.F - Mechanisms • ? Defects in membrane transport enzymes Na+ - K+ - ATPase, or Ca2+ • Sarcoplasmic Reticulum: Ca2+ uptake and release, defects • Myocardial beta-adrenergic receptors decreased
