Recent Findings: Consumption of green tea has been inversely associated with the development and progression of cardiovascular diseases and cardiovascular risk factors [more consumption, less risk].
Mechanisms that have been suggested as being involved in the anti- atherosclerotic effects of green tea consumption primarily entail anti-oxidative, anti-inflammatory, anti-proliferative, and anti-thrombotic properties, as well as beneficial effects on endothelial function. [Atherosclerosis is buildup of plaque on the inner lining of arteries – “hardening” – which reduces ability of vessels to dilate as needed, and may play a role in blockages and thrombi (clots).]
Moreover, evidence exists for myocardial effects of tea constituents, including positive inotropic and anti-hypertrophic effects, and beneficial impact in myocardial ischemia-reperfusion injury. [Inotropic means to increase cardiac contraction strength/output, and anti-hypertrophic means to work against heart enlargement. Myocardial ischemia-reperfusion is when blood supply to heart tissue is blocked or diminished, then returns, resulting in inflammation and oxidative damage.]
Summary: Green tea represents a promising tool for the prevention of cardiovascular disorders.
