Cardiovascular Dangers of Excess Estrogen
Conventional medical dogma states that estrogen is cardio-protective while androgens are pro-atherogenic. This fallacy is based on the mere fact that men have higher levels of heart disease than women.
Excess estrogen in males has many harmful effects, and is definitely not cardio-protective. The following are just a few of the many research studies demonstrating the harmful cardiovascular effects of excess estrogen in males:
1) Increases Risk of Stroke.
After adjustment for age, hypertension, diabetes, adiposity, cholesterol, atrial fibrillation, and other characteristics were made in a group of 2,197 men aged 71 to 93 years of age, men with the highest blood levels of estradiol had a 2.2-fold greater risk of stroke, compared with those whose estradiol levels were lower. www .ncbi.nlm.nih.gov/pubmed/17310026
2) Increases carotid artery thickness.
In a study of 313 men whose average age was 58, carotid artery intima-media thickness was measured at baseline and then three years later. After adjusting for other confounding risk factors, higher levels of estradiol were associated with thickening of the carotid artery wall. Researchers concluded, "Circulating estradiol is a predictor of progression of carotid artery intima-media thickness in middle-aged men." jcem.endojournals.org/content/91/11/4433.full
3) Negatively affects lipids and other risk factors for CAD.
In an angiographic trial of coronary atherosclerosis in a group of men with stable coronary artery disease, significant positive correlations between estradiol levels and other known atherosclerotic risk factors was observed. Researchers concluded, "Our results indicate a possible role of estradiol in promoting the development of atherogenic lipid milieu in men with coronary artery disease." ncbi.nlm.nih.gov/pubmed/15860391
4) Promotes coronary atherosclerosis.
In another angiographic trial of coronary atherosclerosis in men aged 40-60 years, compared with healthy age-matched controls, men with coronary atherosclerosis had higher levels of estrone and a low level of testosterone in the presence of a high level of estradiol. Researchers concluded, "Low levels of total testosterone, testosterone/estradiol ratio and free androgen index and higher levels of estrone in men with coronary artery disease appear together with many features of metabolic syndrome and may be involved in the pathogenesis of coronary atherosclerosis."

5) Associated with heart attacks.
In a study of men having suffered an acute myocardial infarction (heart attack), a prior heart attack, and patients with normal coronary arteries, the results showed significantly higher levels of estradiol in both groups of heart attack patients compared with those without coronary disease. ncbi.nlm.nih.gov/pubmed/17435665
6) Increases Blood Pressure
Excessively high levels of estrogen cause production of superoxide, a potent free radical which damages cell structures and increases blood pressure.
