The outcomes associated with heart failure after myocardial infarction are still poor. Both global and regional left ventricular (LV) remodeling are associated with the progression of the post-infarct patient to heart failure, but although global remodeling can be accurately measured, regional LV remodeling has been more difficult to investigate. Preliminary evidence suggests that post-MI assessment of LV mechanics using stress and strain may predict global (and possibly regional) LV remodeling. A method of predicting both global and regional LV remodeling might facilitate earlier, targeted, and more extensive clinical intervention in those most likely to benefit from novel interventions such as cell therapy.
心肌梗死后心力衰竭的预后仍然较差。整体和局部左心室(LV)重构与梗死后患者进展为心力衰竭有关,但尽管整体重构可以准确测量,但局部 LV 重构更难以研究。初步证据表明,使用应变和应力量化评估 MI 后 LV 力学可以预测整体(和可能的局部)LV 重构。预测整体和局部 LV 重构的方法可能有助于更早、更有针对性地对那些最有可能从细胞治疗等新干预措施中获益的患者进行广泛的临床干预。
