OVERVIEWCongestive Heart FailureIt is the inability of the hearth to pump sufficient blood to meet the needs of the tissues ofoxygen and nutrients. It means the patient has a fluid overload condition (congestion)2 Problems Encountered in CHF1.The ventricles cannot contract vigorously indicating its pumping problem2.Cannot relax or feel fully indicating a feeling problemEtiology1.Atherosclerosis of the coronary arteries – The primary cause of heart failure2.Cardiomyopathy – Dilated cardiomyopathy is the most common the most common typeof cardiomyopathy causes defuses cardiovascular necrosis or cell death in cardio muscleleading to decrease contractility3.Systemic or pulmonary hypertension – There will be an increase pressure in pulmonaryarea, this increases after load or there will be a resistance to ejection which increases thework load of the heart and it leads to hypertrophy (An increase growth of muscle, and ifthere will be increase in cardiac muscle it will impair the hearts ability to feel properlyduring diastole) just like in cardiomyopathy if muscles grow the ventricles will dilateleading now into the inability to feel fully.4.Valvular hearth disease –It will have malfunctions on your tricuspid valves andpulmonary valves because these valves ensure that blood flows in one direction. With thedysfunction blood have increasing difficulty moving forward, so there will be increasingpressure within the hearth and increasing cardiac work load leading to diastolic hearthfailureOther Causes – There are several systemic conditions that contribute to the development andseverity of heart failure.1.Increased metabolic rate (ex: fever, thyrotoxicosis)2.Iron overload (ex: from hemochromatosis)3.Hypoxia4.Anemia (serum hematocrit less than 25%)All of these conditions require an increase in cardiac output to satisfy the systemicoxygen demandClinical Manifestation
1.Systolic heart failure - which is characterized by a weakened heart muscle2.Diastolic heart failure - which is characterized by a stiff and noncompliant heart muscle,making it difficult for the ventricle to fillLeft Sided Heart FailurePulmonary congestions occur when the left ventricle cannot pump blood out of theventricle to the body.Right Sided Heart FailureWhen the right ventricle fails congestions of the viscera means the organs and theperipheral tissues dominates peripheral tissues (extremities) so the heart cant eject blood andcannot accommodate all blood that normally return to it from the venous circulation, so theincrease in venous pressure leads to jugular vein distention, so because of the failure of rightventricle to eject blood it come from superior and inferior vena cava it will cause distendedjugular vein (vein in neck).
