Cardiotonic Agents

The impact of treatment on prognosis of patients with chronic congestive heart failure depends not only on pharmacological therapy but also on nonpharmacological aspects of patient management. Patient compliance, life style changes, salt and fluid restriction, detailed patient information and measures of self control greatly affect therapeutic efficacy.

Reactive oxygen species (ROS) are implicated in many pathogenic processes including the cardiovascular system. Detoxification of ROS by antioxidants (AO) therefore affords protection against such diseases. There is a growing body of evidence suggesting that antioxidants contribute to cardioprotection. Therefore, nine plants that are components of Ayurvedic formulations used for the therapy of cardiovascular diseases were investigated to determine whether antioxidant activity is one of the mechanisms by which these plants exert cardioprotection.

Lagenaria siceraria (Mol.) Standley fruit (bottle gourd), a commonly used vegetable in India is described as cardiotonic and as a general tonic in Ayurveda. Keeping in view the presence of free radical scavenging activity in L. siceraria and involvement of free radicals in the development of various disorders, present studies were designed to evaluate the ethanolic extract of L. siceraria fruit against the disorders where free radicals play a major role in pathogenesis.

Because Ayurvedic herbal preparations contain a myriad of compounds in complex matrixes, it is difficult to establish quality control standards for raw materials and to standardize finished Ayurvedic drugs. A novel, accurate, and valid fingerprint method was developed using HPLC for quality control of a traditional Ayurvedic Arjuna churna formulation, which is used as a cardiotonic drug.

The stem bark of Terminalia arjuna (Roxb.) is used by the Ayurvedic physicians in India for the treatment of various cardiovascular diseases, collectively referred to as hritroga. It has been extensively studied in animal models to demonstrate cardioprotective properties, ranging from positive inotropic- , hypolipdemic-, coronary vasodilatory- and antioxidant effects to induction of stress protein in heart. Various bioactive compounds, like triterpinoids, tannins, flavonoids and minerals have been isolated from the stem bark.

Herbal plants with antioxidant activities are widely used in Ayurvedic medicine for cardiac and other problems. Arjunolic acid is one such novel phytomedicine with multifunctional therapeutic applications. It is a triterpenoid saponin, isolated earlier from Terminalia arjuna and later from Combretum nelsonii, Leandra chaeton etc. Arjunolic acid is a potent antioxidant and free radical scavenger.

The bark of Terminalia arjuna (TA) has been used for centuries in ayurvedic medicine as cardiotonics for treatment of cardiac disorders. It became recently available as over-the-counter supplements marketed for maintaining a healthy heart. However, the cellular mechanism of its cardiotonic effect remains undefined. The present study was designed to investigate the physicochemical property and inotropic effect of the aqueous extract of TA bark (TA(AqE)) on adult rat ventricular myocytes in comparison with extracts prepared sequentially with organic solvents (organic extracts).

Ayurveda is an Indian system of medicine. Despite clinical efficacy, lack of scientific validation has limited the effective use of Ayurvedic drugs. Cardoguard is an Ayurvedic antihypertensive drug formulated by Nagarjuna Herbal Concentrates Ltd., Kerala, India. Left ventricular hypertrophy (LVH) is a modifiable risk factor, and regression of LVH reduces the propensity for adverse cardiovascular events. This study was taken up with the objective of evaluating the efficacy of Cardoguard in the prevention of cardiac remodeling.

OBJECTIVE: Immune and inflammatory signaling pathways, initiated by the innate response, are involved in myocardial ischemia/reperfusion (I/R) injury. Toll-like receptor (TLR) mediated MyD88-dependent NFkappaB pathways play a role in the induction of innate immunity. We have reported that glucan phosphate (GP) improved survival in experimental sepsis, which correlated with decreased tissue NFkappaB activation. In the present study, we report that GP rapidly induced cardioprotection against I/R injury in vivo.

Bromelain (Br), a proteolytic enzyme extracted from the stem of the pineapple, is known to possess anti-inflammatory activity and has been shown to reduce blood viscosity, prevent the aggregation of blood platelets, and improve ischemia-reperfusion (I/R) injury in a skeletal muscle model. We investigated the capacity of Br to limit myocardial injury in a global I/R model. Adult male Sprague-Dawley rats were divided into two groups: control (PBS) and Br at 10 mg/kg in PBS administered via intraperitoneal injection (twice/day) for 15 consecutive days.
