Abstract:
Cardiovascular diseases (CVDs) are expanding at an alarming rate and people's propensity to develop them increases with age. Growing evidence indicates that sirtuins play a pivotal role in regulating a multitude of age-related diseases. Sirtuins are versatile molecules conserved from archaea to mammals. They are regulated by various metabolic and environmental stimuli. Seven sirtuin homologs (SIRT1-7) are present in mammals, with diverse cellular locations. Recent studies have delineated roles of sirtuins in regulating cardiac pathophysiological conditions under various stressors. SIRT1 is the most extensively studied sirtuin, while the role of other sirtuins in maintaining cardiac growth and function is still emerging. In this review we discuss the present understanding of the role of sirtuins in regulating pathophysiological conditions of the heart.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
