原始语种摘要: Abstract(#br)Background(#br)The left ventricular functional recovery by β-blocker therapy is now attributed to time-dependent biologic effects on cardiomyocytes.(#br)Methods and results(#br)To elucidate the cellular mechanism of these biologic effects, we treated 9 patients with dilated cardiomyopathy for 4 months with β-blockers and examined the gene expressions linked to an improvement of left ventricular ejection fraction (EF). Gene expressions of the biopsied right ventricular endomyocardium were assessed by real-time reverse transcription-polymerase chain reaction. A decrease in β-myosin heavy chain (1.23±0.49 versus 0.86±0.45, P <.05) was observed 4 months after the administration of β-blockers. The expression levels of both sarcoplasmic reticulum Ca 2+ ATPase (SERCA) (0.80±0.28...
