Diabetes e o ecocardiograma
Diabetic patients were similar to nondiabetic patients with respect to left ventricular (LV) volume and ejection fraction but had higher LV mass index (104.1 ± 27.5 vs 97.1 ± 28.6 g/m2, P = .009), relative wall thickness (0.41 ± 0.08 vs 0.38 ± 0.07, P < .0001), and left atrial volume index (LAVi) (26.2 ± 8.1 vs 24.0 ± 8.2 mL/m2, P = .008)—all parameters that were significantly related to the risk of death or HF hospitalization . American Heart Journal Issue: Volume 162(4), October 2011, p 685–691 . Conclusions: After high-risk MI, diabetic patients were at higher risk of death or HF and demonstrated greater baseline LV mass index, relative wall thickness, and LAVi as well as greater left atrial enlargement at 20-month follow-up. These findings suggest greater baseline concentric remodeling and long-term elevation in LV diastolic pressure post-MI among diabetic patients, which may partially mediate this risk. . Estudo demonstra alterações da massa ventricular nos diabético com Infarto que implicam em pior prognóstico.
Ressalta a importância de um exame bem feito e capaz de definir o risco aumentado.
