Functional consequences of diminished myocardial oxygen delivery per beat in experimental heart failure

1

Heart failure is characterized by cardiac dysfunction leading to inadequate oxygen delivery to tissues, influenced by various genetic and environmental factors.
2

Coronary microvascular dysfunction is a significant predictor of major adverse cardiovascular events and is linked to myocardial fibrosis and myocyte death.
3

The study investigates how heart failure affects coronary blood flow, myocardial oxygen consumption, and contractile function using a swine model.
4

Findings suggest that heart failure reduces coronary vasodilation and autoregulatory capacity, impacting myocardial perfusion and oxygen delivery.
5

The research aims to clarify the relationship between coronary blood flow and heart failure progression, providing insights into potential therapeutic targets.
