Vata dynamics with special reference to cardiac disorders - A cross-disciplinary approach

Vata is one of the fundamental patho-physiological entities with unique and dynamic properties. All actions inside the body, whether voluntary or involuntary, are governed by Vayu. Actions involved during natural physiological calls or urges, are involuntary, but partially under voluntary control. Classical texts from Ayurveda state that such natural urges (NU) should be strictly attended without disturbing their natural flow. Some urges can be intentionally or inadvertently initiated (Udiran) or suppressed (Dhaaran), redirecting the normal flow of Vayu, leaving scopes for severe morbidities in the heart causing cardiovascular disorders (CVD). Since Vata has unique attribute of Vega (locomotion) that moves in a specific direction, its intensities can be quantified with the help of modern techniques. Few studies have objectively evaluated the intensities of NU like belching, sneezing, expulsion of flatus, etc. during normalcy, which may help us to determine their altered activity during morbidity. In spite of such studies, their relevance to CVD is inadequately explored. Hence, this article addresses details of such NU that lead to CVD alone, from classical texts of Ayurveda, conventional medicines and technology that quantify their intensities. Citing research articles from various journals using keywords were done to understand their mechanism along with their intensities. It was found that objective estimation of few NU was performed extensively whereas some had limitations. Theories from the classical texts confirm that physiological NU, if allowed to flow freely without any impedance, assures good health. It would certainly benefit the mankind if their pathologic state is timely detected so as to prevent disease progression in CVD.
