Objective: In Āyurveda, ‘Hṛudaya’ is much beyond the idea of muscular organ - Heart, established as both physiological and psychological head office, a pivotal functional centre. 1) To elucidate the fundamental role of Agni, Tridosha regulation and Mahābhūta interactions in functions of Hṛudaya. 2) To interpret unexplored and extended cardiovascular physiology through an Āyurvedic lens. Data Source: Charaka Samhita, Sushruta Samhita, Bhela Samhita, Ashtanga Sangraha, Ashtanga Hrudaya, Shabdakalpadruma. Review Methods: A textual and conceptual synthesis of cardiovascular physiology and classical Āyurvedic principles was undertaken. Stage wise functionality of Hṛudaya were analysed and interpreted for its Agni, Tridosha regulation and Mahābhūta interactions alongside corresponding biomedical mechanisms like electrical conduction and hemodynamic. Discussion and Results: There exists two states Hrudaya Viaksana and Mlanata (metabolically active and inactive states subjectable to diurnal variations). Hṛudaya Dhmana (pumping action of the Heart) is powered predominantly by Agni and Vāyu, supported by Prāṇa, Apana, Samānavāta, and Sadhaka Pitta, while Rasa Vikshepana (circulation of nutrients) involves Avalambaka Kapha enhancing the quality of Ahāra Rasa Gati. The sequential kinetic energy transfer in Srotas, governed by Akasha, Vayu and Agni Mahābhūta modulated by Jala and Pṛthvī circulates the transforming Ahara Rasa is. Disruptions in either of this led to multiple cardiovascular pathologies. Conclusion: Hṛudaya’s cardiovascular functions are deeply rooted in the synergistic interaction between Mahābhūtas reflected in functioning of Doṣas and, regulating the life-sustaining circulation and vitality. Thus, integrative model provides a holistic understanding of cardiac physiology, reinforcing the relevance of Āyurvedic insights in cardiovascular care.
