In adults with type 2 diabetes and heart disease, a weekly injection of tirzepatide reduces the risk of heart-related death, heart attack, or stroke just as effectively as another drug called...
Mechanism
Synthesis from 1 study
Tirzepatide helps the body control blood sugar better and lose more weight than dulaglutide, which in turn reduces harmful fat buildup and inflammation in blood vessels. This makes it less likely for plaques to rupture or block arteries, preventing heart attacks and strokes — even though it does...
Most probable mechanism
Tirzepatide helps the body use insulin better and reduces hunger, leading to lower blood sugar and weight loss. This lowers fat buildup in blood vessels, reduces inflammation, and eases pressure on the heart, which together prevent heart attacks, strokes, and heart-related deaths.
Tirzepatide binds to and activates both GLP-1 and GIP receptors on pancreatic beta cells
Receptor activation increases insulin secretion and reduces glucagon release, lowering blood glucose levels
Lower blood glucose reduces oxidative stress and improves function of the blood vessel lining
Activation of GLP-1 and GIP receptors in the brain and fat tissue reduces appetite and increases fullness, leading to weight loss
Weight loss reduces fat around internal organs, lowering levels of inflammatory signals and improving fat metabolism
Improved lipid profile (lower triglycerides and LDL) and reduced blood pressure decrease plaque buildup and arterial stiffness
Reduced vascular inflammation and improved endothelial function stabilize atherosclerotic plaques and reduce clot formation
Lower cardiac workload and improved heart efficiency reduce the likelihood of heart attack and sudden cardiac death
