Heart failure
1 Heart failure
DEFINITION HEART FAILURE the pathophysiological state in which the heart is unable to pump blood at a rate commensurate with the requirement of the metabolizing tissues or can do so only from an elevated filling pressure. Usually caused by a defect in myocardial contraction(myocardial failure
2 DEFINITION • HEART FAILURE – the pathophysiological state in which the heart is unable to pump blood at a rate commensurate with the requirement of the metabolizing tissues or can do so only from an elevated filling pressure. – Usually caused by a defect in myocardial contraction (myocardial failure)
DEFINITION CONGESTIVE HEART FAILURE Clinical manifested as Pulmonary congestion Systemic congestion Inadequate tissure blood perfusion HEMODYNAMICALLY heart failure (cardiac dysfunction) is diagnosed when LVEDP>18mmHg or RVEDP>10mmHg
3 DEFINITION • CONGESTIVE HEART FAILURE – Clinical manifested as • Pulmonary congestion • Systemic congestion • Inadequate tissure blood perfusion • HEMODYNAMICALLY heart failure (cardiac dysfunction) is diagnosed when – LVEDP>18mmHg or – RVEDP>10mmHg
UNDERLYING CAUSES Primary myocardial dysfunction(systolic and/or diastolic) Cardiomyopathy Primary or secondary metabolic disturbances of myocardium Overloading of heart Pressure overloading Ⅴ olume overloading limited diastolic function
4 UNDERLYING CAUSES • Primary myocardial dysfunction (systolic and/or diastolic) – Cardiomyopathy – Primary or secondary metabolic disturbances of myocardium • Overloading of heart – Pressure overloading – Volume overloading – limited diastolic function
