近年来国外对心肌梗塞后左室重构的发生发展过程、临床意义、可能的预防及治疗措施做了较详细的研究.左室重构在心肌梗塞后病人中较常见,是慢性持续进行性的病理生理过程,主要表现为心室容积扩大及心室构型改变。左室重构早期主要是梗塞扩张,远期为非梗塞段室壁增厚及延长.重构后的左室容积准确反映心功能,与病人的远期预后密切相关。梗塞后早期静滴硝酸酯类或卡托普利能减轻梗塞扩张,长期口服卡托普利可能减轻远期的左室重构,但能否改善病人远期存活率尚需进一步研究.
In recent years abroad, the occurrence and development of left ventricular remodeling after myocardial infarction, clinical significance, possible prevention and treatment measures to do a more detailed study. Left ventricular remodeling in patients with myocardial infarction is more common, chronic persistent progressive The pathophysiological process, mainly for the expansion of ventricular volume and ventricular configuration changes. Left ventricular remodeling is mainly the early expansion of infarction, the long-term non-infarction wall thickening and extension of the left ventricular volume after reconstructed accurately reflect cardiac function, and the patient’s long-term prognosis are closely related. Early intravenous infusion of nitrates or captopril after infarction can reduce infarction expansion, long-term oral captopril may reduce long-term left ventricular remodeling, but can improve the long-term survival of patients needs further study.
