Cardiovascular diseases (CVD) are a group of chronic conditions involved in blood vessels or the heart.
Depending on the location that has been affected, CVD can be classified into 6 main types including
* Ischemic heart disease, the most form of cardiovascular disease in the Western world caused by partial blockage of blood flow in the arteries, leading to reduced oxygenate blood circulation to the heart muscle.
* Strokes are caused by the reduced circulation of blood in the blood vessels of the brain due to blockage or breaking capillaries.
* Congenital heart disease is a condition caused by the defective structure of the heart arising because of a birth defect.
There are many factors associated with the risk of CVD. Epidemiologically, hypertension, high blood cholesterol, smoking, medical conditions such as diabetes, obesity, physical inactivity, family history, and women with PCOs are some CVD prevalent risks.
The more factors you have, your risk of CVD is higher compared to those with less.
Out of the aforementioned risk factors, some researchers in the examination of the risk of atherosclerosis increased at an alarming rate over the past few decades and suggested that CVD may be correlated to the promotion of a high-fat diet in the same period.
Dr. Frank M. Sacks said, ",...randomized controlled trials that lowered intake of dietary saturated fat and replaced it with polyunsaturated vegetable oil reduced CVD by ≈30%, similar to the reduction achieved by statin treatment".
And, "Prospective observational studies in many populations showed that lower intake of saturated fat coupled with higher intake of polyunsaturated and monounsaturated fat is associated with lower rates of CVD and of other major causes of death and all-cause mortality".
In other words, a long-term high-fat diet has a strong implication in elevating the onset of CVD.
Alliin (S-allyl-L-cysteine-S-oxide) is a phytochemical compound sulfoxide,. a derivative of the amino acid cysteine, belonging to the class of sulfur compounds, found abundantly in fresh garlic and onion.
With an aim to find a natural cardioprotective ingredient, researchers examined the effects of short-term treatment with two doses of CPSSA on cardiovascular risk factors associated with the metabolic syndrome, in comparison to the effects of allicin and captopril separately.
Allicin (8 mg/(kg day)) protected the heart function by significantly reducing insulin, triglycerides, and homocysteine concentrations and blood pressure compared to Captopril (50mg/(kg day)) which improved only on blood pressure and homocysteine.
Allylmercaptocaptopril (CPSSA), a new stable synthetic compound produced by the chemical reaction between allicin and the angiotensin-converting enzyme inhibitor captopril with low dose (5mg/(kg day)) lowered SBP but did not improve any other measured parameter, while treatment with a higher dose (50mg/(kg day)) significantly decreased blood pressure, triglycerides, and homocysteine concentrations.
In other words, allicin and captopril protect the heart synergetically by inhibiting the conditions associated with the risk of cardiovascular disease.
Based on the findings, Dr. the lead scientist wrote," The combined molecule CPSSA integrates the anti-hypertensive, lipid-lowering, and homocysteine-reducing effects of both allicin and captopril, making it a potential cardiovascular protective agent.".
Taken altogether, alliin used alone or combined with other herbal medicines may be considered supplements for the prevention and treatment of cardiovascular disease, pending the confirmation of the larger sample size and multicenter human study.
Intake of alliin in the form of supplements should be taken with extreme care to prevent overdose acute liver toxicity.
