心力衰竭的临床后果,部分是由于加重心脏负担的继发性生理学变化所造成的。上述许多生理紊乱能用药物控制,从而提高心输出量,往往会获得满意的症状改善。由以下主要原因所引起的心力衰竭如甲亢、贫血或房颤,是可针对病因治疗的。药物治疗基础心力衰竭可通过控制液体潴留和改善心输出量来处理。泵功能的力学改善可以由降低心脏工作负荷而获得,包括控制心室肌在 The clinical consequences of heart failure are due in part to secondary physiological changes that exacerbate the burden of the heart. Many of the above-mentioned physiological disorders can be controlled with drugs, thereby increasing cardiac output, often with satisfactory symptomatic improvement. Heart failure such as hyperthyroidism, anemia or atrial fibrillation caused by the following main causes can be treated for the cause. Basic medical treatment of heart failure can be handled by controlling fluid retention and improving cardiac output. Mechanical improvement of pump function can be obtained by reducing heart workload, including control of ventricular muscle in
