Definitions heart failure

各種定義

• Failure of heart to pump blood forward at rate sufficient to meet metabolic demands of peripheral tissues, or ability to do so only at abnormally high cardiac filling pressures
• Low output (↓ cardiac output) vs. high output (↑ stroke volume ± ↑ cardiac output)
• Left-sided (pulmonary edema) vs. right-sided (↑ JVP, hepatomegaly, peripheral edema)
• Backward (↑ filling pressures, congestion) vs. forward (impaired systemic perfusion)
• Systolic (inability to expel sufficient blood) vs. diastolic (failure to relax and fill normally)
• Reduced (HFrEF, EF <40%), mildly reduced (HFmrEF, EF 40–49%), & preserved (HFpEF, EF >50%); combination of systolic and diastolic dysfxn may occur regardless of EF
