Diabetic cardiomyopathy—What do we know about it?

World Journal of Cardiovascular Diseases 2013年第5期3卷 26-32页

Diabetic cardiomyopathy is defined as the presence of myocardial dysfunction in patients with diabetes in the absence of coronary artery disease, hypertension, or other known cardiac disease. Diabetes has been shown to affect the heart through various cellular mechanisms leading to enhanced myocardial fibrosis, left ventricular hypertrophy, systolic and diastolic dysfunction. With increasing incidence of type II diabetes mellitus, it has continuously rising health and financial implications in both developed and developing countries. Hyperglycaemia seems to be the main deriving force, and careful glycaemic control as well as early administration of neurohormonal antagonists currently remains the mainstay of therapy. Many newer treatment targets are currently being explored. Here we present a brief review of its pathophysiology, association with heart failure symptoms, and management strategies.

AIM To investigate the characteristics and outcomes of octogenarians who presented with ST-elevation myocardial infarction(STEMI) compared to non-octogenarians and to investigate the outcomes of octogenarians that received primary percutaneous coronary intervention(PCI) compared to those managed *** We performed a single center retrospective case controlled study. All octogenarians who presented with STEMI to a tertiary referring hospital between 2007 and 2012 were included. The subsequent non-octogenarian patient who presented with a STEMI following the octogenarian patient was assigned to the control group in a 1:1 manner. The outcomes measured were peri-procedural cardiac arrest, death on table, cerebrovascular accidents(CVA), in-hospital and 30-d mortality. RESULTS A total of 146 patients were analyzed. The octogenarian group had a higher percentage of females, higher overall comorbidities, higher Charlson Comorbidity Index score, worse renal function and were more likely to require residential care and home help. The octogenarian group were also less likely to have PCI attempted and had a longer symptom onset to PCItime. Mortality rate was high amongst octogenarians who presented with STEMI. However, those managed conservatively had a higher in-hospital and 30-d mortality rate CONCLUSION Octogenarians who presented with STEMI that were managed conservatively had a higher mortality rate compared to those who had primary PCI. Therefore,we propose that revascularization may be beneficial to patients in this age group.
