Bromelain and Cardiovascular Risk Factors in Diabetes

Maelezo
According to American Heart Association (2010), heart disease and stroke are the No. 1 causes of death and disability among people with type 2 diabetes. At least 65% of people with diabetes die from some form of heart disease or stroke. Type 2 diabetes is associated with a two to fourfold increased incidence of ischemic cardiovascular events and markedly enhances the risk of stroke(Coutinho et al, 1999) due to a variety of associated risk factors that include high blood pressure, lipid disorders, high low-density lipoproteins (LDL) cholesterol, high triglycerides, low high-density lipoproteins (HDL) cholesterol, smoking, obesity, lack of physical activity and poorly controlled blood sugars(American Heart Association 2010).
Bromelain, a crude extract from the pineapple plant, was first introduced as a therapeutic compound in 1957 (Heinicke & Gortner, 1957). Heinicke et al. (1971) reported that bromelain was effective for use in cardiovascular diseases as an inhibitor of blood platelet aggregation, minimizing the risk of arterial thrombosis and embolism.
A literature review identified only three human studies (in Honolulu and Germany). In view of this review and the valuable therapeutic properties of bromelain to cardiovascular disease, there is a need for a study to confirm bromelain's use for cardiovasular disease.
This study is a randomized placebo control, parallel design, and double blind, pilot efficacy study which was carried out in Hebei Yiling Hospital, China. The study assessed the effects of 12 weeks of bromelain (1050mg/day) supplementation on plasma fibrinogen level compared to usual care. Study participants were type 2 diabetes who have a risk of developing cardiovascular disease.
