病理■心腔扩张■室壁变薄:弥漫性纤维斑痕形成-附壁血栓心肌细胞肥大,变性,纤维化
病 理 ▪心腔扩张 ▪室壁变薄:弥漫性 ▪纤维斑痕形成 ▪附壁血栓 ▪心肌细胞肥大,变性,纤维化
临床表现Symptoms of heartfailure-pulmonary congestion (left HF)dyspnea (rest, exertional, nocturnal)orthpneasystemic congestion (right HF)edema,nausea,abdominalpain,nocturia(起病隐匿,发病即表现为心功能不全,严重心衰)
临床表现 ⚫ Symptoms of heart failure –pulmonary congestion (left HF) dyspnea (rest, exertional, nocturnal), orthpnea –systemic congestion (right HF) edema, nausea, abdominal pain, nocturia (起病隐匿,发病即表现为心功能不全,严重心衰)
low cardiac output :fatigue and weakness>低血压(hypotension)>心动过速(tachycardia)>呼吸急促(tachypnea>猝死(suddendeath)》心律失常(cardiac arrythmia)
low cardiac output : fatigue and weakness ➢低血压 (hypotension) ➢心动过速(tachycardia) ➢呼吸急促(tachypnea) ➢猝死(sudden death) ➢心律失常(cardiac arrythmia)
