Are there specific animal models used to study cardiometabolic disease induction methods?
Scientists rely on animal models to understand how diseases like heart failure and diabetes develop. These models often involve inducing obesity through diet, creating heart attacks, or using genetic changes to mimic human conditions. This approach helps researchers test new treatments before trying them on people.
What the research says
One common method involves feeding animals a specific diet to cause obesity and metabolic issues. Researchers have used this diet-induced approach in mice to study how intermuscular fat expands and causes disease 4. Another major method is inducing a heart attack, or myocardial infarction, in mice to see how the heart recovers or fails 5.
Researchers also use genetic tools to create models that mimic human disease risks. For example, scientists have studied mice with specific gene knock-outs or overexpression to see how these affect heart function after an injury 5. Additionally, studies have reviewed hundreds of papers to see how often researchers label their rodent models as having heart failure with preserved ejection fraction, a common type of heart disease 6.
Some models focus on the gut microbiome. Researchers use animals to study how changes in gut bacteria affect the host and lead to cardiovascular disease 7. These studies show that the gut bacteria in animals can influence disease risk in ways similar to humans.
