Protective effect of Galectin-3 inhibitor against cardiac remodelling in an isoprenaline-induced myocardial infarction in type 2 diabetes

Type 2 Diabetes mellitus (T2DM) has the potential to impair cardiac function and cause heart failure. We aimed to study the cardioprotective influence of Galactin-3 (Gal-3) inhibitor; modified citrus pectin (MCP) in isoprenaline induced myocardial infarction (MI) in T2DM rats. Forty rats were allocated into 4 groups; groups I and II served as control. T2DM was provoked in groups III and IV by serving them high fat diet followed by a single low dose of Streptozotocin (STZ), then group IV were administered MCP in drinking water for 6 weeks. Groups III and IV were then subcutaneously injected isoprenaline hydrochloride once daily on the last 2 successive days to induce MI. MCP restored echocardiographic parameters with significant decline in Gal-3 area % in cardiac tissue alongside protection against cardiac remodelling. our data showed that there is a protective potential for Gal-3 inhibitor (MCP) against cardiac injury in isoprenaline induced MI in T2DM.
