Green Tea and Its Bioactive Epigallocatechin gallate EGCG in Reduced Risk and Treatment of Cardiovascular Diseases

Green tea containing bioactive polyphenols may have a strong implication in reduced risk and treatment of cardiovascular disease, some scientists postulated.

Cardiovascular disease is a chronic medical condition characterized by narrowed or blocked blood vessels that can lead to a heart attack including chest pain (angina) or stroke.

According to statistic, heart disease is the second leading cause of death, claiming more than 48,000 lives every year.in Canada.

In the differentiation of green tea bioactive polyphenols epigallocatechin gallate or EGCG in risk of cardiovascular disease researchers at the joint study lead by the Colorado State University found that application of EGCG activated the expression of the nuclear erythroid-2 like factor-2 (Nrf2) transcription factor in stimulated transcription of antioxidative genes in protection of cell against oxidative stress in induction of CVD.

Compared to statins, the conventional medicine may be effective in reduced heart attacks and strokes in people at moderate and high risk but it can also cause cancers and multi-drug resistance cancer, EGCG ameliorated the risk of CVD without giving rise to adverse effects.

Further analysis of EGCG efficacy in risk of cardiovascular disease and metabolic syndrome by searching literature published online of major scientific databases, from 1995 to 2017, scientists found that EGCG exhibits a wide range of therapeutic properties including associated with the inhibition of LDL cholesterol in reduced risk of plague accumulated in the arterial wall in elevated risk of atherosclerosis, attenuated angiotensin II (AngII) through inhibiting transcription factor NF-κB in induced abnormal enlargement, or thickening of the heart muscle, and reduced risk of highly oxidative enzyme myeloperoxidase(MPO) activity in promoted myocardial infarction, as level of myeloperoxidase(MPO) is considered as a biomaker used in assessment of risk of heart attack.


Additionally, EGCG also exerted significant and profound effects in the ameliorated risk of diabetes through lowering plasma glucose and glycated hemoglobin level, inhibited pro-inflammatory factors in elevated inflammation in the early phase of acute infection and chronic infection as well as blocking expression of ROS in stimulated free radical chain reaction through its antioxidant activity.



Dr. Eng QY, after taking into account of other confounders, siad, "EGCG shows different biological activities and in this review, a compilation of how this bioactive molecule plays its role in treating cardiovascular and metabolic diseases".

Moreover, in a total of 9 studies including 259,267 individuals satisfied the criteria and guideline included in the meta-analysis. by examining published literature in evaluated the association between green tea consumption, CVD, and ischemic related diseases. up to October 2014, researchers indicated that for a nongreen tea drinker, risk of CVD was 1.19, intracerebral hemorrhage was 1.24 and cerebral infarction was 1.15 in compared to people who drank <1 cup green tea per day.

Not surprisingly, people who drank 1-3 cups of green tea per day had a reduced risk of myocardial infarction 0.81, and stroke 0.64 in compared to those who drank <1 cup/day and who drank ≥4 cups/day had a reduced risk of myocardial infarction of 0.68 in compared to those who drank <1 cup/day.

And for people who consumed ≥10 cups/day of green tea were also shown to have lower LDL in compared to the group who drank <3 cups/day.

Dr. Pang J, the lead author at the final stage of the experiment said, "(The) meta-analysis provides evidence that consumption of green tea is associated with favorable outcomes with respect to risk of cardiovascular and ischemic related diseases".
The results finding of all studies confirmed that consumption of green tea is associated with favorable outcomes with respect to risk of cardiovascular disease as well as expression of various serum markers in the compilation of how green tea initiated protective activity against CVD.
